IN THIS ISSUE: FOCUS ON HEALTH SERVICES AND HEALTH DISPARITIES SPRING 2010

NERI’s new Institute for

Health Services and Disparities

Research, co-directed by

Lisa Marceau and John McKinlay,

builds upon decades of research on the

organization and use of health services,

while expanding the focus to include

health care disparities.

NERI’s many pioneering factorial experi-

ments concerning physician decision

making reveal health care disparities to

patient interactions with the health

care system. That is, they are “socially

constructed” as a result of doctors’

decision making with certain categories

of patient.

This research approach has deep theo-

retical roots and important implications

for programs designed to reduce or

eliminate health disparities. Focusing on

individual at-risk behaviors and increasing

access to care is unlikely to attack some

root causes of health disparities.

Current efforts often overlook the

“upstream” sociopolitical and economic

determinants of “downstream” health

care disparities. NERI’s approach, often

termed “healthy public policy,” shifts

the focus away from “downstream”

behavior (health education to reduce

risk factors) and even “midstream”

organizational approaches (reengineering

health care and improving access) to

“upstream” socio-political interventions

to improve population-level health.

Ever-widening health disparities are a major publichealth concern in the U.S. and many other countries.

An important example of this trend is disparities seen in the

prevalence of type 2 Diabetes Mellitus (T2DM), which afflicts

about 21 million adults in the US alone. Disparities in T2DM

are often thought to be “caused” by race and ethnicity, which

has spurred a well-intentioned search for genetic and bio-

physiological explanations.

NERI researchers, however, have shown that socioeconomic

status (SES), a potentially modifiable influence, has a much

stronger impact on the disparities in T2DM prevalence than

race or ethnicity. This suggests that the continuing focus on

NERI continues to

GROW

Despite the recession, NERI has continued to thrive and expand in new ways.

NERI has not cut or frozen salaries, it has granted a number of promotions,

and has maintained its merit increase program.

NERI is currently in the midst of a recruitment boom with about 12 positions open. In part,

this is because NERI is expanding the types of services it offers and the types of “customers”

it can work with. In addition, NERI was awarded a multi-million dollar grant for expanding

the Pediatric Heart Network Study. This unique project has allowed for internal

promotions and an expansion of current employee capabilities, while creating new positions

for external candidates, particularly those from the private sector who have experience and

capabilities in industry-sponsored research.

NERI’s Survey Research Center is experiencing an uptick in project work and is rapidly

hiring experienced field and telephone interviewers as it services a wide range of research

projects. The Data Management group, supervised by Patti Nash, has also expanded rapidly.

Six data managers have completed certification from the Society for Clinical Data

Management. Several also attended the annual data manager conference, which was held

in Seattle this year.

NERI has also seen significant growth in several other areas. Three PhD epidemiologists

were awarded funding for proposals submitted to the NIH. Karen Lutfey has created a new

center for Patient-Provider Relationships. The Institute for Epidemiology, directed

by Andre Araujo, has seen an increase in funding for on-going projects in collaboration with

several private companies.

This brief review and other research synopses in this newsletter provide a flavor of the exciting

new work getting underway at NERI.

Many aspects to these questions could

be explored, but here I want to consider

one simple, yet critically important,

aspect of this question: the common

confusion between the distribution of

a measure in the data and the sampling

distribution of its mean. These are

elements of every introductory statis-

tics class, and yet much confusion

arises simply because this distinction

is too often neglected.

First let’s quickly review the statistical

ideas. A measure of interest, such as

systolic blood pressure (SBP), has a

distribution in the population. We

rarely get to measure every individual’s

value, however, so we instead collect a

representative sample. This sample has

a mean, which is estimated as the sum

of the individual values divided by the

size (“n”) of the sample. The sample

also has a variance, which is defined as

the expected squared deviation of any

randomly chosen observation from the

sample mean. The square root of the

variance is known as the “standard

deviation,” and is a common measure

of the spread of the data around the

mean. If we took many independent

samples of size n, then the observed

sample mean values would have a

distribution of their own.

As long as the sample size n is not very

small, this sampling distribution will

be “normally” distributed, regardless

of the distribution of the original data.

(A “normal” distribution has the shape

of the familiar “bell-shaped curve.”)

The sampling distribution of the mean

also has a variance, usually referred to

as the “standard error of the mean.”

For a sample size n of any reasonable

size, this is much smaller than the

standard deviation of the original data.

In order to show using a statistical test

that one population mean is “signifi-

cantly” different from another, it is

necessary that the difference in the

two means be large in comparison with

their standard errors. Since the stan-

dard error gets smaller as the sample

size n gets larger, one can almost

always find a difference between two

means with a large enough sample size.

A “significant” difference in this sense,

however, does not correspond to a

difference that is large with respect to

the distribution of the actual data. This

is the point that is often overlooked in

the consideration of evidence of race

differences to medical treatments.

Let’s take the example of ACE

inhibitors — a class of medications

that lower blood pressure. It is widely

believed that ACE inhibition is less

effective for black patients than for

white patients, and this disparity in

therapeutic efficacy is mentioned in

most hypertension textbooks and

clinical guidelines. The British

Hypertension Society Guidelines even

When Should be a Factor in Determining Medical Treatment?

In 2005, the FDA approved the first “race-specific” drug, BiDil, a medication for heart failure targeted to blacks.

More race-targeted therapies are apparently in the development pipeline. But is it really true that medicine should

be practiced differently for one race of patient than another? Is race really more than skin-deep?

“Junk Sleep” and itsEffects on ChildrenSleep is an underappreciated health

habit…We all know that junk food is

unhealthy for our children, but so is junk

sleep. Healthy sleep is to the brain what

healthy food is to the body.

— Marc Weissbluth, MD

Poor sleep is an underappreciated

health habit and an unmet pub-

lic health problem. We all stay

up later than we should, get up earlier

than we’d like, and are awoken more

times than we care to admit in the

middle of the night. Research clearly

demonstrates that the cumulative

effects of poor sleep have significant

negative health impacts. Growing

evidence supports the fact that sleep

is an essential healthy behavior and a

key factor in disease prevention —

particularly in pediatric populations.

The importance of good sleep, however,

is continually under-appreciated by both

parents and health care professionals.

Unhealthy sleep habits in children

often impact negatively on mood,

behavior, attention, cognitive out-

comes, and on overall quality of life.

These apparent deficits may not always

be recognized by parents and may be

overlooked by providers as resulting

from inadequate sleep. A number of

factors give this issue particular

urgency, including:

• Inadequate sleep is increasingly preva-

lent in children, particularly in socio -

economically disadvantaged groups

• Poor sleep quality is linked to

impaired physical and mental health

and other unhealthy behaviors in

children

• Sleep habits are learned behaviors,

which are amenable to behavioral

change

• Healthy sleep behaviors adopted in

childhood may help prevent lifelong

problems

• Sleep disorders may be missed or

misidentified in the pediatric popula-

tion, which has important implica-

tions for subsequent clinical treat-

ment and management

To improve awareness of sleep problems

in children, NERI is collaborating

with pediatric physician Judith Owens

at the Alpert Medical School at Brown

University to produce a CME-accredited

web-based training program for primary

care providers and ultimately an

accompanying web site for parents.

Funded through a Small Business

Innovation Research (SBIR) grant from

the National Institutes of Health, the

project aims to raise awareness of sleep.

Culturally Appropriate Messages

The new Sleep Habits project will:

• Identify existing systems for

recognizing age and culturally

appropriate screening and surveil-

lance of pediatric populations

• Emphasize the importance of early

detection of sleep problems in

children and the role of cultural

differences in infant sleep.

• Present strategies aimed at prevention

of sleep problems, with consideration

of culturally relevant differences

• Emphasize the importance of

culturally sensitive education for

both parents and providers

• Review the basic biology of sleep

and its relationship to one’s cultural

environment, beliefs, and values

A companion web site will target parents

with the goal of educating them about

the importance of good sleep habits for

their children. Importantly, this program

will include culturally and racially

diverse populations, recognizing that

the manifestations of unhealthy sleep

practices, sleep health promotion, and

“anticipatory guidance” during well

child visits must be presented within

diverse cultural contexts.

Blood Diseases a Focus of NERI Research Efforts

Thalassemia and sickle cell

disease are two common

diseases of the blood. Both

diseases produce a range of serious

symptoms and can shorten life span

and impair quality of life. Both also

can be treated with regular blood

transfusions, and yet this life-saving

treatment can damage the body by

causing iron overload in the heart,

liver and endocrine glands.

NERI is involved in a large number of

studies aimed to improve the diagnosis

and treatment of these two serious

diseases. Understanding the molecular

biology and genetics of thalassemia

and sickle cell disease as well as

gaining an understanding of standards

of care, patient clinical characteristics,

and life style attributes may ultimately

improve the quality of life for millions

of people around the world.

Thalassemia Research

Thalassemia is actually a group of

disorders that is caused by a wide

range of mutations in the genes that

code for hemoglobin, the molecule

in red blood cells that carries oxygen.

(Different kinds of mutations cause

sickle-cell disease, which is explored

later in this article.)

In July, 2000, the National Heart,

Lung, and Blood Institute (NHLBI)

led the founding of the Thalassemia

Clinical Research Network (TCRN),

a global network of clinical centers,

with NERI serving as the Data

Coordinating Center. The network

includes sites in Lebanon, Turkey,

England, Canada, and the United

States all of which have a high density

of people with thalassemias.

In addition to support from NHLBI,

the Thalassemia Clinical Research

Network gets important aid from

the Cooley’s Anemia Foundation

(CAF), a non-profit, privately-funded

organization named for Dr. Thomas

Benton Cooley, one of the early

pioneers in thalassemia research.

The CAF supports patients involved

in the TCRN by providing funds for

travel for patients to make hospital

visits to TCRN sites, for patient educa-

tion and patient training.

Four studies conducted by the

Thalassemia Clinical Research Network

will contribute to the scientific body

of knowledge for this set of diseases:

• Thalassemia Longitudinal Cohort

Registry will provide a long-term

understanding of standards of care,

quality of life, and detailed genotypic

and phenotypic characterizations.

• Low Bone Mass Observational

Study in Thalassemia will estimate

the prevalence of low bone mass in

thalassemia patients and will evaluate

the interaction of factors such as

endocrine and genetic influences

on bone metabolism in hopes of

identifying preventive strategies and

effective treatments.

• Pulmonary Hypertension in

Thalassemia Pilot Interventional

Drug Study with Comparison

to Controls will evaluate the safety

and efficacy of sildenafil to treat

pulmonary hypertension (PHT).

Thalassemia patients frequently

have undetected PHT, and this study

will compare how thalassemia

patients and those without PHT

respond to treatment.

• Pain in Thalassemia Descriptive

Studies will assess, using a survey,

the prevalence of pain in subjects

purpose of this study is to find out if

one treatment plan is better than the

other in controlling sickle cell pain.

NERI is also the Data Coordinating

Center for a second NHLBI study of

sickle cell disease. The primary purpose

of the PROACTIVE feasibility study is

to determine if it is possible to design

and complete a randomized trial to

assess the effectiveness of a transfusion

in preventing a pneumonia-like disorder

called acute chest syndrome (ACS).

The study will determine if patients

at high risk of ACS can be reliably

identified using specific values of a

special substance (sPLA2) in sickle cell

patients hospitalized with pain. This

preliminary study will also ascertain if

high risk patients can be enrolled in

a complex Phase III trial in sufficient

numbers to answer the question of

transfusion effectiveness.

Because of its involvement in many

studies of thalassemia and sickle cell

disease over the last two decades,

including the most recent ones high-

lighted here, NERI has become a

world leader in both fundamental and

clinical research into these diseases,

and is playing a pivotal role in the

effort to increase quality life expectancy

in these populations.

The studies mentioned in this article are supported by Thalassemia ClinicalResearch Network Cooperative Grant#U01 HL065238 and the Sickle Cell DiseaseClinical Research Network CooperativeGrant #U10 HL083721.

with transfusion and non-transfusion

dependent thalassemia. The Pain

in Transfusion sub-study will assess

whether reports of pain vary over

the transfusion cycle.

Sickle Cell Disease

Sickle cell disease is a group of inherited

disorders of red blood cells that affect

millions of people worldwide. Healthy

red blood cells are round, and carry

oxygen to all parts of the body. In sickle

cell disease, genetic mutations cause

the red blood cells to become hard and

sticky and look like a C-shaped farm

tool called a “sickle.” The sickle cells

die early, which causes a constant

shortage of red blood cells. Also, when

they travel through small blood vessels,

they get stuck and clog the blood flow.

This results in impaired circulation,

chronic ill health, and premature death.

The disease cannot be cured, but

treatments exist for the symptoms

and some of the complications of the

disease. Bone marrow transplants may

offer a cure in a small number of cases.

NERI serves as a Data Coordinating

Center for the IMPROVE trial,

sponsored by the NHLBI. This trial

is investigating the use of patient-

controlled analgesia (PCA), which is

where the patient is in control of his or

her pain medicine. In this study, two

different treatment PCA plans will be

used to treat people with sickle cell

disease who are admitted to the hospital

for a pain crisis, which is an attack of

pain caused by the clumping of blood

cells in some part of the body. The

Because of its involvement in manystudies of thalassemia and sickle cell disease, NERI has become a world leader in both fundamental andclinical research into these diseases.

the population-based prevalence of ED

and is still the only major longitudinal

study of ED.

Two recent papers from the MMAS

have added significant weight to the

contention that ED does, in fact,

predict CVD (see Figure 1) and CVD

death, even when statistically adjusted

for known cardiovascular risk factors.

Indeed, ED is as strongly related to

CVD as known high-risk conditions

such as hypertension or diabetes.

Data from these papers indicate that

the risk of CVD is about 40% higher

in men with ED.

The evidence linking ED and CVD

implies a common systemic vascular

etiology. This is based on the premise

Linking ErectileDysfunction andCardiovascular Disease

Erectile dysfunction (ED) is a

common condition estimated to

affect 10-20 million men in the

U.S. Increasing evidence suggests that

ED may be caused by changes to the

blood vessels in the penis. Half of all

ED cases in men over the age of 50 are

attributed to atherosclerosis or plaque

build-up in the blood vessels.

Scientists have speculated for years that

the onset of ED, insofar as it represents

damage to the arteries in the penis,

may provide an early warning sign of

impending coronary events. This has

important implications from a public

health standpoint, because sometimes

men die from a sudden cardiac event

who have had no signs of cardiovas-

cular disease (CVD).

Recent and ongoing research conducted

at NERI using data from the Massachusetts

Male Aging Study (MMAS) and the

Boston Area Community Health

(BACH) Survey has provided informa-

tion addressing the potentially impor-

tant issue of whether ED might serve

as a barometer for CVD.

The MMAS, which enrolled 1,709 men

between 40-79 years of age, is widely

considered a landmark study in the

fields of aging and endocrinology. Men

from the MMAS have been followed

over a period of about 15 years.

MMAS was the first study to report

that the early functional consequence of

atherosclerosis — loss of the capacity

of blood vessels to open up manifests

symptomatically earlier in the small

blood vessels of the penis than in larger

(e.g., heart) vessels. This is known as

the “artery-size” hypothesis.

Furthermore, there is strong evidence

that a dysfunction in the endothelial

cells of blood vessels, which is charac-

terized by reduced levels of nitric

oxide, is the likely biologic mechanism

underlying both ED and CVD. NERI

recently received a grant from the

National Institutes of Health (Principal

Investigator: Varant Kupelian) to con-

duct an ancillary study of the Boston

Area Community Health (BACH)

Survey to investigate this hypothesis.

The goal of the proposed research is to

provide the first systematic investigation

of the relationship between endothelial

dysfunction and ED in a large popula-

tion-based sample of men. About 400

subjects from the BACH Survey will

visit Dr. Joseph Vita’s Vascular Testing

Laboratory at the Boston University

School of Medicine for study assess-

ments. Endothelial function will be

measured in the brachial artery of the

forearm.

Erectile function will be assessed

using a validated self-report measure:

the International Index of Erectile

Function. The presence and extent

of endothelial dysfunction will be

compared to both severity of ED and

changes in erectile function over time.

The study will cost-efficiently draw on

the wealth of background demographic,

biomedical and psychosocial data on

the well-characterized cohort of the

parent BACH Survey.

NERI has a long and proud history of

making substantial contributions to

the field of urology, with MMAS and

BACH staff serving as the foundation.

The recent publications and recently-

awarded grant to NERI will add to

a growing literature on ways to

potentially identify men at risk for

the number one killer in the world:

cardiovascular disease.

This research is supported by Grant#DK080662 from the National Institute ofDiabetes and Digestive and Kidney Disorders.

Kids and Heart Disease:Speeding Clinical Discovery

It can take decades for the results

of basic laboratory research to be

translated into treatments available

to patients. This long delay is particu-

larly wrenching when the patients

are children. To speed the transfer of

laboratory (“bench”) research about

pediatric heart disease to clinical trials

and studies, the National Heart, Lung,

and Blood Institute has instituted a

translational research initiative called

the Bench to Bassinet Program. NERI

has been named the Coordinating

Center for the Program.

This multi-year, multi-million dollar

effort will establish two new research

consortia: the Cardiovascular

Development Consortium (CvDC)

and the Pediatric Cardiac Genomics

Consortium (PCGC). The CvDC aims

to generate and disseminate compre-

hensive data about the molecular

pathways that regulate cardiovascular

development. The goal of PCGC is to

identify genetic and epigenetic causes

of human congenital heart disease,

and relate genetic variants present in

the congenital heart disease patient

population to clinical outcomes.

The nine Research Centers in these

Consortia will align and interact with

the existing clinical research network,

the Pediatric Heart Network (PHN)

and its Data Coordinating Center,

which NERI has overseen and run for

the past 9 years. NERI will apply this

long-term experience to its new role

as organizer and manager of the

various facets of the Bench to Bassinet

Program. As part of its responsibilities,

NERI will provide information and

data systems support, administrative

and public websites, logistical and

meeting support, and contractual and

payment arrangements for selected core

research facilities. NERI’s work in the

Bench to Bassinet Program is led by

Sharon Tennstedt and Lynn Sleeper.

NERI has a unique understanding of

the challenges and solutions associated

with research in pediatric populations.

Fifty percent of NERI clinical trials and

registries include pediatric participants,

often with rare disorders, encompass-

ing over 22,000 subjects located in

roughly 500 national and international

research sites. NERI has served as the

coordinating center for the NHLBI

Pediatric Cardiomyopathy Registry

since 1994, and the Fall of 2009 began

in a similar role for an FDA-sponsored

Pediatric Cardiac Device Consortium.

In addition, NERI recently received a

grant from the federal Small Business

Innovation Research program to develop

a CME program prototype focused

on pediatric sleep. NERI’s pediatric

credentials also include the development

of the No More Hand-Me-Downs

campaign for the NHLBI. That program

is designed to raise awareness and

educate parents about pediatric clinical

research. For more information visit:

http://www.nhlbi.nih.gov/childrenand

clinicalstudies/index.php.

This research is supported by NHLBI grant#U01 HL098188.

The dictum “No good deed goes unpunished”

clearly applies to the ongoing controversy

surrounding recommendations of the US

Preventive Services Task Force (USPSTF), an independent

group of 16 private sector clinicians and scientists

appointed by the federal Department of Health and

The Mammogram Controversy

Human Services, which rigorously assesses ever-changing

evidence on medical care, and makes recommendations

based on explicit criteria.

Before reviewing the controversy that erupted from these

recommendations, here is some relevant statistical context.

According to the National Cancer Institute about

192,000 women in the U.S. will be diagnosed with breast

cancer and over 40,000 died of the disease in 2009.

Those sound like big numbers, but they translate to a

life-time risk of breast cancer of 2.86%. The risk that a

woman aged 40 will be diagnosed with invasive breast

cancer before her 50th birthday is 1.44%. And the risk

that a 40-year old woman will die of breast cancer before

her 50th birthday is tiny: 0.19%. And yet every year,

about 39 million women undergo mammograms in

the U.S., costing the health care system an estimated

$5 billion annually.

HEALTH SERVICES AND HEALTH DISPARITIES

ON NOVEMBER 16, 2009, THE TASK FORCE:

• Reversed a recommendation made in 2002, and said

that women in their 40s should stop having annual

mammograms, except for a small group known to be

at high risk for breast cancer

• Recommended that women aged 50-74 should have

mammograms every 2 years rather than every year

• Said that breast self-examinations produce no

significant medical benefit and that doctors should

not teach women to perform them

Page 10: EXPLORIN G HEALT H CARE DISPARITIES N

HEALTH SERVICES AND HEALTH DISPARITIES

10

The new guidelines sparked immediate,

and heated, controversy from practically

every quarter. Patient advocacy groups

and some breast cancer experts and

scientists welcomed the new guide-

lines, noting that mammograms

produce false-positive results in about

10% of cases, causing anxiety and

prompting many women to undergo

follow-up testing, sometimes disfigur-

ing biopsies, unnecessary surgery,

harmful radiation and chemotherapy.

But many groups, such as The

American Cancer Society, vigorously

defended the old guidelines saying they

have reduced mastectomies and saved

thousands of lives annually. Physician’s

unions and professional societies, too,

reflexively denounced the new guide-

lines, as did many prestigious medical

centers. Cancer survivors and their

families presented personal moving

accounts of how mammography has

saved lives. Needless to say, the makers

of mammography machines were

apoplectic.

In due course, the current controversy

will die down, and the USPSTF recom-

mendations are likely to be viewed

as the gold standard and followed.

Medicare, for example, generally

adopts panel recommendations when

it makes coverage decisions for seniors,

and private insurers usually follow

suit. The new guidelines are expected

to alter the grading system for private

health plans. The National Committee

for Quality Assurance has already

announced the way in which it grades

private insurers will change as a result

of the new guidelines.

In the meantime, there are some

compelling lessons to be gleaned from

this episode.

Lesson OneThe acceptability of new guidelines

depends more on the preservation of

stakeholder interests and political

considerations than on the quality of

scientific evidence. While lip service is

given to the sanctity of evidence-based

medicine, the best new evidence will

be disparaged and dismissed if it runs

counter to established interests.

Lesson TwoThe development of clinical guidelines

needs to be completely overhauled.

Unlike every interest group either

opposed to or in support of the new

mammography guidelines, the USPSTF

has no dog in the hunt. The task force

is independent, nonpartisan, and

comprises well-intentioned respected

scientists who are prepared to under-

take public service for minimal reward,

often at considerable personal and

professional cost. This is not the case

for many other clinical guidelines

which are heavily influenced by the

pharmaceutical industry and special

interest groups.

Guidelines should be developed with

federal sponsorship by independent

scientists with no interest in a particular

outcome. The independent National

Institute for Health and Clinical

Excellence (NICE) in the

UK provides a model

for how things could

be done in the U.S.

Given public confusion

continued from page 9

and anxiety surrounding the release

of guidelines and results of other

federal initiatives, the means of their

effective dissemination is as important

as the method of their independent

development.

Lesson ThreeThe way in which guidelines are cur-

rently developed (with heavy influence

of various interests) and in many cases

disparaged (if challenging the status

quo and prevailing interests) makes

a mockery of the laudable goal of

evidence-based medicine. The success

or failure of clinical guidelines is

presently determined by political

processes, not by the quality of the

science dispassionately analyzed

by qualified independent experts.

Appropriate support from federal

sponsors is a sine quo non.

In an ironic postscript — on the same

day USPSTF members were being

interrogated by a congressional

committee, the results of a new Dutch

study revealed that mammographic

screening doubles the risk of breast

cancer among high-risk women and

the researchers urge avoidance of

repeated exposure, especially at younger

ages. If the USPSTF had included these

latest data from the Netherlands would

it have made any difference?

race/ethnicity as the primary determi-

nants of T2DM disparities overempha-

sizes the importance of biomedical

factors and diverts efforts from more

important and potentially modifiable

social determinants.

Diabetes disparities likely result from

many different influences including:

• Structural (e.g., SES)

• Demographic (e.g., age and gender)

• Environmental (e.g., neighborhood

location and accessibility of

medical care)

• Behavioral (e.g., nutrition and

physical activity)

• Bio-physiologic (e.g., insulin resistance

and inflammatory processes)

• Genetic (e.g. family history)

Employing a multi-level approach,

NERI is beginning a large, community-

based epidemiologic study to disentan-

gle the relative contribution of these

different influences on T2DM disparities.

The research has several distinguishing

features. Because it is not clear when

in the natural progression of T2DM

disparities first becomes evident, our

study is uniquely focusing “upstream”

at the early pre-diabetes stage of the

condition. As illustrated in Figure 1

(on the cover), although there may be

some race/ethnic (or socio-economic)

differences in the pre-diabetes phase

of this disease (sometimes termed the

“Metabolic Syndrome”) these differ-

ences may be amplified by variations in

clinical decision making after patients

access the health care system.

Thanks in part to NERI research, it

is now known that widely-used race/

ethnic classifications do not accurately

characterize genetically distinct sub-

populations. The race label “African-

American” for example, does not

define a unique genotype, whereas

the geographical origin of a person’s

ancestors may.

With clinical colleagues at the

Massachusetts General Hospital

(Harvard Medical School) NERI

researchers are now able to identify

a set of genetic markers that align

with a person’s geographic ancestry.

These markers can then be used to

help characterize the genome of

people with mixed ancestries, which

will improve the accuracy of estimates

for the genetic component of a

person’s risk for T2DM. These are

Getting to the Root of Diabetes Disparities

This effort requires broad multi disciplinary expertise and an ecumenical approach to research,

minimally including observational surveys, experimental studies and careful qualitative analyses.

NERI’s perspective is illustrated by two new NIH-supported studies — an experiment examining

clinical decision making when different types of patients, who have been activated by direct-

to-consumer advertising, request specific pain medications, and an epidemiologic study of the

multi-level contributions to race/ethnic disparities in pre-diabetes.

This newsletter features articles on these and other research efforts designed to improve thedelivery of effective and equitable health care and understand root causes of health disparities.

called ancestry-informative markers

(AIMs) and they allow researchers to

reliably estimate ancestry proportions

for an individual. They represent a

truly unique feature of NERI’s health

disparities research.

The potential implications of this study

are enormous. By focusing on risk

states preceding the onset of T2DM,

the study will contribute to the under-

standing of upstream disparities. In

addition, the study results may help

prioritize strategies for primary and

secondary prevention of T2DM.

By including neighborhood effects, it

will clarify the role of environmental

influences on the creation of T2DM

disparities, and with the inclusion of

bio-physiologic influences such as

AIMs, it will enhance understanding of

basic disease processes and pathways.

Gaining a multilevel understanding of

the development and amplification of

disparities in diabetes will arm health

care providers, researchers and policy

makers with a broad set of tools to

intervene at the appropriate level and

with the appropriate audience.

This research is funded with grant#DK080786 from the National Institute ofDiabetes and Digestive and Kidney Diseases.

The Center grows out of

ongoing work being done in

the Institute on Health Services

and Disparities Research. The patient-

provider relationship has changed a

great deal in recent decades, and as

a result has become increasingly

important for understanding health

services and disparities.

The importance of the patient-provider

relationship has long been recognized.

Fifty years ago, sociologist Talcott

Parsons developed the concept of the

“sick role” to explain patients’ roles

and social expectations when they were

sick. The sick role was a temporary

status taken in response to acute

symptoms. The patient was released

from social obligations while recovering,

but was also morally obligated to seek

help from an expert and follow medical

advice for how to get better. This por-

trait of a passive patient responding to

an authoritative medical doctor helped

set an agenda for research on related

topics such as health care utilization,

help-seeking, and treatment compliance

(later renamed “adherence” or

“concordance”).

These research agendas were driven in

part by modernist ideologies reflecting

the prominence of medical science and

emphasizing the importance of medical

intervention. The perspective was that

patients would experience desired

positive health outcomes if they would

just act rationally by seeking help and

follow the advice of their health care

providers. This emphasis on medical

authority was complemented by

homogeneity in the educational and

professional pipelines that produced

health care, including who trained to

be physicians (white men), their options

for types of professional positions

(physicians) and the types of environ-

ments in which they would work

(fee-for-service, often solo practice).

Together, these ideologies and

professional systems contributed to

a “Marcus Welby” model of patient-

provider relationships in which the

physicians were the experts and

patients were expected to be passive

consumers of this expertise.

Today, however, many of these factors

have changed, and the patient-provider

relationship is no longer viewed as a

simple conduit for doctors to give

patient information. For starters,

the terminology has changed: “doctors”

have become “providers” and“patients”

have become “clients” or “consumers.”

The biology has also changed: the

epidemiologic transition observed in

western countries has led to increased

chronic illness and lower morbidity

and mortality associated with acute,

infectious disease.

As a result, public health and medical

efforts are increasingly focused on pre-

ventative and palliative care rather than

waiting to treat acute symptoms after

they appear. With advances in medical

knowledge and testing, definitions of

what it means to be sick have also

expanded. More conditions are medical-

ized (i.e. “shift work sleep disorder”),

and people who are not ill but are

at risk for a condition can become

“patients” in the health care system.

At the same time, patients now often

bring their own expertise and initiative

to the relationship. They have

New Center Examines the

Patient-Provider RelationshipNERI has launched a new research initiative called

the Center on Patient-Provider Relationships,

which will expand this long-standing scientific focus.

increased access to health-related

information through the internet and

direct-to-consumer advertising, both of

which help shift the content of medical

knowledge from the physician’s head

and medical books to widely available

venues that patients can access and

use. Furthermore, consumerist atti-

tudes encourage patients to actively

use this information in their own best

interests.

These circumstances make “patient-

hood” a longer-term condition (poten-

tially life-long), and more expansive

insofar as it includes a wider range of

indicators (rather than just “symptoms”

that make a person feel sick), and

requires more self-care and more sur-

veillance for potential developments.

Under such conditions, it is less possible

for patients to be temporarily dismissed

from their daily responsibilities —

instead, sickness (or potential sickness)

become integrated into everyday life.

To the extent that these broader defini-

tions reach all members of society,

this vigilance against potential sickness

requires increased mutual support

and cooperation from family members

and friends.

Large-scale organizational changes

in the health care system also have

implications for the patient-provider

relationship. The rise of managed care

in the US was accompanied by increased

emphasis on evidence-based medicine

and the emergence of Bayesian decision

making as the dominant approach to

medical statistics in the 1970s. These

changes further contributed to a sense

that outcomes and actions were no

longer defined by providers based on

their professional expertise, but rather

by managed care incentive structures,

reimbursement mechanisms, and

practice guidelines derived from

evidence-based medicine. These

changes led to changes in thinking

about how to measure variations,

mistakes, and health care disparities.

Given these conditions, more attention

has been paid to exactly what happens

in the allotted time patients and

providers have together. Bias in physi-

cian decision making, including

intended and subconscious overreliance

on patient demographics in making

diagnostic and treatment decisions,

make up an increasing portion of

research in patient-provider relation-

ships. Results consistently show

variations by patient characteristics,

provider attributes, health care systems,

and country, even when patients’

presenting symptoms are identical.

Topics such as miscommunication,

discrimination, diagnostic uncertainty,

and responses to stigma are all consid-

ered potential keys to understanding

sources of health disparities stemming

from within the medical encounter.

The new Center is already actively

engaged in exactly this type of

research. The National Institute on

Mental Health has funded a major

study of how physician decisions

regarding the diagnosis and treatment

of diabetes varies when the patient has

a stigmatizing comorbidity such as

schizophrenia or depression. But this

is just a start. In the years to come,

the Center on Patient-Provider

Relationships expects to play a major

scientific role in this critical aspect

of the overall health care system.

This research is supported by grant#MH081824 from the National Institute of Mental Health.

Patients now often bring their own expertise and initiative to the relationship.

HEALTH SERVICES AND HEALTH DISPARITIES

Effective Primary Health Care (PHC) appears

essential to both individual and population

health. An ongoing relationship with a specially

trained generalist physician, who is accessible

and provides comprehensive care, is something

everyone prefers, once it is experienced.

For many different reasons, primary health care is under

serious threat in the US, perhaps even heading towards

extinction. The term “crisis” has been used to capture the

present situation. Recognizing the important contribution

of PHC for both individual and population health, can we

“Save Dr. Ryan”?

First, let’s consider what will almost certainly not save

“Dr. Ryan”. Simply rewrapping traditional PHC in well-

intentioned concepts and calling it something else is unlikely

to work. In the past few decades concepts such as a “Medical

Home,” or a “Patient-Centered Medical Home” and later

“An Advanced Medical Home” were developed as “innovative”

approaches to the organization and delivery of PHC.

14

HOW DO WE SAVE DR.RYAN ?“ ”Important stakeholders including legislators, private

foundations, large employers, patient groups, and certainly

organized medicine, have championed the “Medical Home”

as the centerpiece of a “new” approach to the delivery of

health care, and more recently even health care reform.

A medical home is not a place, like a house or a hospital,

but rather an approach to providing PHC. Ideally, and at a

minimum, PHC delivered through the medium of a Medical

Home should be: accessible, continuous, comprehensive,

family centered, coordinated, compassionate, and culturally

appropriate.

There are claims that widespread implementation of medical

homes would decrease health care costs by 5.6% annually

(approximately $67 billion), with substantial improvement

in the quality of care provided and reductions in health

disparities. We certainly hope these things will happen.

A limited evaluation of medical homes is presently underway,

however this does not include appropriate experimentation

(e.g. cluster randomization of participating practices to

appropriate comparisons), hence it is unlikely to produce

results robust enough to inform evidence-based policy.

• Primary care physicians (PCPs) express high levels of workplace discontent

• Most medical students avoid PHC and instead choose careers in more lucrative medical specialties

• Non-physician health workers now venture on turf once the exclusive domain of PCPs

• The inaccessibility of PCPs is reported by patients and repeatedly confirmed by independent surveys

• Lacking any (or adequate) health insurance, millions of people have no PCP and seek care

from retail clinics or inappropriately use emergency departments for everyday medical needs

ROOTS OF THE CRISIS IN PRIMARY CARE

Newly empowered patients tell their PCPs what they have

and what treatment they expect. The inexorable increase in

medical information and resulting specialization continues

to threaten the basis of generalist medicine. Most PCPs are

now corporatized salaried employees who manifestly advance

organizational needs, resulting in some erosion of patient

trust. Primary care delivered by nurse practitioners in retail

clinics now offers an effective, cost efficient, and satisfying

alternative to traditional PHC for many routine medical

problems (which constitute the bulk of a highly trained and

costly doctor’s workload).

The recent health care reform debate in the US reveals the

modern state more responsive to macro economic interests

than the protection of well-established prerogatives of the

medical profession. With few notable exceptions, most

PCPs and PHC stakeholders appear, perhaps understandably,

“heads down” and focused on the more immediate features

of care inherent in the notion of a medical home, with their

backs to the underlying forces which threaten the future of

PHC in the US.

Improving access and continuity, payment reform, changes

to the medical curriculum, and practice-level improvements

like the introduction of electronic records, and introduction

of online tools to help patients manage information and make

more informed decisions are all worthwhile improvements.

But even if successfully introduced they are unlikely to save

“Dr. Ryan.”

While hoping PHC in the US may be reinvigorated by the

medical home initiative it is reasonable to ask if the medical

home represents any fundamental or structural change.

Many PCPs claim to have provided this type of care for

ages. And despite expressions of patient-centeredness, many

elements of medical homes appear designed to protect and

advance PCP interests — for example, they require “a personal

physician, physician-directed medical practice, and enhanced

access and adequate payment.” The physician remains the

captain of the team, despite its composition and the nature

of the patient’s illness.

Doubtless, the organization, financing, and delivery of PHC

in the US can be substantially improved, but the “changes”

presupposed by the notion of a medical home are unlikely

to bring this about. The medical home represents a repackag-

ing of traditional facets of PHC which preserve dominant

physician and organizational interests and actually represent

very little change at all. By itself, the medical home is unlikely

to save “Dr. Ryan.”

Any true solution to this complex issue must start with

recognition of the underlying causes and a deep understanding

of the magnitude of the problem. The more important origins

of the demise of PHC are social and political. Health and

medical care are now considered to be like other commodities,

to be bought and sold. Medical information and increasingly

medical care itself is available from the internet.

• Some PHC is increasingly available online

• PCPs appear relegated to a gate-keeping function

• The inflation-adjusted income of PCPs continues to decline

NERI’S WORK ON THE FUTURE OF PRIMARY CARE DOCTORING, OUR SAVING DR. RYAN PROJECT, HAS TWO ESSENTIAL FEATURES:• Recognition that PHC is essential to the health of both individuals and the general population• Identification of the upstream social, political and economic factors, which constitute both the greatest threats

to PHC and also offer promise for policy-level interventions to save PCPs

go so far as to state that blacks should

have first line treatment with calcium-

channel blockers or thiazide diuretics,

whereas Whites should be treated first

with ACE-inhibitors, angiotensin

receptor blockers, or b-blockers. The

authors of these guidelines justify the

recommendation by citing the “signifi-

cant” differences in the mean blood

pressure responses between these two

race groups that have been published

in the scientific literature. But let’s

examine this “difference” a little bit

more carefully.

Meta-analysis of randomized trials

including US blacks and whites who

were given monotherapy with ACE

inhibitors shows that the mean systolic

blood pressure (SBP) response for

blacks is about 4 millimeters of

mercury (mmHg) less than for whites.

Nonetheless, while this difference in

population means is highly statistically

significant, it is a small difference

compared to observed within racial-

group variability. Whites have a mean

SBP decline in response to treatment

of nearly 11 mmHg, but the standard

deviation is more than 12 mmHg. Since

these mean responses have “normal”

distributions, this latter number

indicates that about two-thirds of SBP

change values for whites obtained

from a random sample will fall between

-1 and 23 mmHg (i.e. ± 1 standard

deviation). For blacks, the mean SBP

response is 7 mmHg, while the stan-

dard deviation is 15 mmHg. Thus,

racial differences are quite small com-

pared with the variation within each

race group (See Figure 1). This implies

that knowing which group a patient

belongs to tells a clinician little about

their individual response to treatment.

Based on this simple example, there-

fore, statistical reasoning would not

support race-based clinical decision

making when it comes to treating

hypertension. This is consistent with

other lines of evidence that strongly

suggest problems with a race-based

approach. To begin with, racial groups

are defined in terms of social and

cultural affiliations, and therefore are

naturally imbued with the associations

gleaned from everyday life in American

society. This makes them a poor choice

for serving as biomedical quantities

because they naturally suggest to the

clinician the patterns of traits and

characteristics that are linked in the

popular imagination to the group,

even when these are inaccurate.

Various experimental trials have docu-

mented under controlled conditions

the irrational and inappropriate use

of racial identity in medical decision-

making. For example, a 1988 experi-

ment by Loring and Powell provided

dummy psychiatric case presentations

that were intended to represent

undifferentiated schizophrenia, and

labeled these as coming from patients

who were black or white and male or

female. The profiles were then assigned

continued from page 3

When Should Race be a Factor in Determining Medical Treatment?

a diagnosis by psychiatrists who

returned questionnaires through the

mail. Black patients, especially black

men, were much more likely to be

assigned the diagnosis of paranoid

schizophrenia, indicating that clinicians

perceived in these descriptions greater

degrees of violence, suspiciousness and

dangerousness than for the identical

white patients.

More fundamentally, it is well known

that racial classification is only trivially

correlated with genetic variability. It

is therefore unsurprising that biologic

traits relevant for medical decision-

making tend to be largely overlapping

across racial groups, and that race is

thus largely uninformative in diagnosis,

prognosis and treatment. In the simple

example of antihypertensive treatment

with ACE-inhibition, we saw that

although there is a “significant” differ-

ence in blood pressure response to

the medication between race groups,

this difference is too small (relative to

within-group variability) to be applied

clinically to decisions involving an

individual patient.

Many people know that they

ought to think ahead and

create documents that clearly

express their values and preferences

about medical care in the event they

cannot do so themselves. But this is

often easier said than done. For one

thing, decisions must be made about

diseases (e.g. dementia) about which

people may be unclear.

In addition, choices must be made

about medical treatments, such as

mechanical ventilation, which may also

be unfamiliar. Finally, it can be difficult

to find the right forms to fill out and

to know how those forms need to be

tailored for particular states.

A project recently undertaken by NERI

is aimed at overcoming these barriers

in order to make advance care planning

easier. A prototype interactive video

decision aid has been developed that

presents documentary films of patients

with several end-stage health condi-

tions and various types of end-of-life

“I didn’t realize thatyou could make all of these decisions. If I had a stroke likemy mother and lost my speech, I would wantothers to know my wishes.”

care or treatments. These films are

complemented by dramatic films that

model effective communication with

health providers and family about

preferences for end-of-life care. The

decision aid is presented on a tablet

computer to facilitate use in a busy

health care setting. Users are also able

to complete an advance care document

that can be uploaded electronically to

their medical record and printed out.

The decision aid has been developed

by Sharon Tennstedt and Angelo

Volandes, MD, at Massachusetts

General Hospital.

Feasibility testing of the prototype in

a primary care setting shows that this

interactive decision aid is likely to help

people make more informed choices

in advance care planning, and offers

some significant benefits above and

beyond that offered by traditional

print materials or verbal discussions

held with health care providers.

This project is funded by NIH grant#NR010825.

Making Better DecisionsAbout End-of-Life Care

Completed: Online Training Course About PTSDAs reported in NERI’s 2009 newsletter, there is a tremendous and continuing

need for high-quality mental health services. This is particularly true for

individuals suffering from Post-Traumatic Stress Disorder (PTSD). Cognitive

Behavioral Therapy (CBT), which is a well-known and effective form of

psychotherapy, is not as widely used with PTSD patients, perhaps because of

the intensity of the training required.

To address this need, NERI has recently completed a comprehensive online

training course on CBT as it is used for patients with PTSD. The goal is to

remove the well-known barriers to learning the skills needed for using CBT

with these clients. Development of the course has been successfully completed,

and evaluation of the program has begun, with the enrollment of participants

who work within the Veterans Affairs (VA) system. After completion of the

study, the online training course is planned to be opened for broader access.

This study is funded by Department of Defense grant #W81XWH-08-2-0089.

The Boston Area Community

Health/Bone (BACH/Bone)

Survey is an observational

research study of musculoskeletal

health conducted among 1,219 racially

and ethnically diverse men aged 29-80

years. Subjects for this study were

recruited from the parent study, BACH.

The baseline BACH/Bone examinations

occurred between 2002 and 2005.

NERI recently received a grant from

the National Institute on Aging

(Principal Investigator: Andre Araujo)

to conduct a second examination of the

BACH/Bone Survey cohort. These

examinations are scheduled to begin

early in 2010.

The BACH/Bone Survey represents a

comprehensive effort to understand

the fundamental causes of racial and

ethnic differences in markers of the

two primary ‘upstream’ determinants

of fracture: loads applied to bone and

bone fragility. This is particularly

important for the study of osteoporosis,

since persons with the disease often

feel no symptoms until a fracture occurs.

Furthermore, it recognizes the fact that

fractures have two main determinants

which may interact with one another:

events that apply extreme force to the

bone (e.g., falls) and weakness of the

bone material itself (see Figure 1 for

the conceptual model that informs the

research).

Therefore, to understand racial and

ethnic differences in fracture rates,

it is critical to consider factors that

influence loads that are applied to bone

(e.g., fall risk, body composition and

physical function) as well as factors that

influence bone strength and quality

(e.g., the bone’s tissue density, material

arrangement, and microstructure).

In the second examination, subjects

will once again visit the General

Clinical Research Unit at the Boston

University School of Medicine (BUSM),

where they will have bone density

tests performed. This will therefore

represent one of the few studies with

the ability to compare longitudinal

rates of bone loss among men of

different racial and ethnic groups.

While at the Research Unit, subjects

will also be scanned with a machine

that was recently acquired through the

NIH grant that uses high-resolution

peripheral quantitative computed

tomography (HR-pQCT) to estimate

bone quality on a microscopic level.

The use of this device is one of the

unique aspects of the BACH/Bone

Survey. There are very limited data on

bone microarchitecture in population-

based studies and no data that examine

racial and ethnic differences in bone

microarchitecture.

In addition, during the second exami-

nation, the portion of the protocol

assessing loads applied to bone will be

greatly expanded to include a compre-

hensive assessment of balance, muscle

strength, walking speed, and other

tests of physical function. These

measurements will be performed at

the Laboratory of Exercise Physiology

and Physical Performance at BUSM.

The BACH/Bone study is poised to

make substantial contributions to our

understanding of the elusive mechanisms

underlying racial and ethnic differences

in bone fragility. Ultimately, the study

could provide insights that will inform

the development of fracture prevention

strategies as well as rational approaches

to resource allocation.

The BACH/Bone Survey is funded by grant#AG020727 from the National Institute on Aging.

Chronic pain is a costly, debili-

tating condition that ripples

through all aspects of a

patient’s life. Work and family roles

can change, and overall physical and

emotional health can be impaired.

There has been growing interest by

health care organizations to encourage

providers to better monitor and treat

intractable pain in the face of mounting

pressures to do more in less time.

Allowing patients to monitor and

record their pain levels with electronic

diaries (EDs) has been recognized as

one possible solution to better pain

management and treatment. The focus

of these efforts has been on improving

how pain is documented so that

providers can better manage the

patient’s pain. Little research, however,

has looked at how the use of EDs

might directly impact the patient’s own

attitude and perception of their pain.

NERI, in collaboration with Robert

Jamison of the Brigham and Women’s

Pain Management Center, recently

conducted a study to explore this

question — and found surprising

results. Qualitative interviews with

patients who took part in a larger

randomized trial, uncovered some

key findings that suggest previously-

unrecognized benefits of using EDs:

• Use of electronic diaries

improved patient understanding

and acceptance of their pain

• Improved self-management

• EDs reduced patient reliance

on medical treatments

• EDs were easy to use and

• Patients reported changing their

behavior

These findings challenge the notion

that electronic tracking will necessarily

result in improving medical treatments.

Instead, the findings suggest that

patients who track their pain using

EDs may better understand how to

cope with their condition through

increased awareness of their pain.

This greater understanding can have

positive benefits such as improved

patient-doctor communication, and

a greater tolerance for the way pain

affects daily life. In essence, appropriate

treatment may be better supported

when patients better understand their

pain. These results provide a new

perspective on the utility of electronic

tools for reducing health care costs

and improving patient quality of life.

NERI has been at the forefront

of research into the ways that

patient characteristics influ-

ence diagnoses and clinical decision

making. Such things as a patient’s

gender, race, age, and perceived socio-

economic status can produce variations

in treatment that are unrelated to the

actual symptoms presented.

The Veteran’s Administration (VA)

realized several years ago that gender-

based variations in treatment might

be a significant issue since VA patients

have, until recently, typically been

male.

To improve gender-awareness, the

VA worked with NERI to develop a

CD-based training program called

Caring for Women Veterans. The

program’s efficacy was assessed through

care. If a disease is etiologically related

to social affiliations and environments,

then race could be treated as a real

and consequential part of a patient’s

history and circumstances, with

important implications for a wide

range of experiences and exposures.

The existing track record for appropri-

ate consideration of race in medicine

is not very encouraging thus far,

however, and one may doubt whether

a social variable with such profound

historical connotations can ever be

used dispassionately, without invoking

all the irrational debris of its sordid use

continued from page 16 as an instrument of social oppression.

Nonetheless, the standard for modern

medicine should be clear. Medical

uses of racial classification should be

viewed suspiciously until justified by

compelling evidence. The traditional

practice of using racial descriptive

labels reflexively for all patients,

for example, should be reconsidered.

Just as race-specific newborn screening

for sickle cell trait in the US was

examined and ultimately abandoned

as unwarranted, so too should racial-

ized guidelines for treatment, such

as those of the British Hypertension

Society, unless or until it can be shown

that such recommendations provide a

real benefit for patients and clinicians.

The Times They Are a Changin’: Women in the VApretest-posttest equivalent control

group evaluation at the VA. A key

study outcome demonstrated that

this training increased sensitivity and

knowledge of gender issues within

VA staff. Because of the importance of

addressing this need, the VA is once

again working with NERI to transfer

the CD-based training to a web-based

application. The new Caring for

Women Veterans training program

will greatly expand access to this

important information within the VA

and is an example of NERI’s commit-

ment to translating basic research

into real-world actions that make a

difference in people’s lives.

NERI Gives Back to the CommunityOne man and his car came to pick up the presents that had

been bought and wrapped by NERI employees for the 2009

Snow Kids Gift Drive. He took one look at the massive pile

and reached for his cell phone. One car was clearly not going

to be enough!

In the end, it took 4 cars to transport the more than 150 gifts

donated by NERI staff. As in the past, NERI worked with the

local Department of Social Services, which identified families

in need and detailed how NERI staff could help. This year

NERI provided five area families with gifts for 22 children,

ages 2 to 15. Gifts included toys, musical instruments,

clothes, household items, and gift cards.

Ensuring High-Quality Clinical Data Management

Averitable Amazon of clinical data pass through

NERI computers every year. Managing these data,

analyzing them, and presenting them for external

use is a massive challenge that NERI has consistently

met over the years. One way NERI does this is by adhering

to a set of principles known as Good Clinical Data

Management Practices (CGDMP) which are maintained

by The Society for Clinical Data Management (SCDM).

The SCDM is dedicated to advancing the discipline

through education and a commitment to the highest

standards of clinical data management practices.

The SCDM has established a certification exam to enhance

the credibility of its guidelines and clinical data managers

who pass the exams. The exams are rigorous and test

a manager’s knowledge in a variety of areas including

protocol review, case report form (CRF) design, external

data quality, metrics and adverse event review and

reconciliation. Once an eligible data manager has passed

the exam and been accredited, he or she is recognized

in the clinical research world as trained, qualified, and

committed to the clinical data management profession.

All NERI clinical data managers are members of the

SCDM and take advantage of training opportunities offered

by the organization. To date, seven NERI clinical data

managers have passed the SCDM exam and are Certified

Clinical Data Managers.

Opening New Career Paths at NERIIn its ongoing efforts to

create a dynamic workplace

that can respond to the

energy and talents of moti-

vated staff members, NERI

has recently implemented a

series of changes to the way

staff can advance profession-

ally. For example, a dual

career “ladder” has been created, which can help staff who

are currently on scientific or research career paths take

positions in management. In addition, job descriptions and

some job titles have been revised so that they conform to

industry and government standards. Staff members who do

not currently have a PhD can now progress on the manage-

ment side of the “ladder” with existing MS or BS degrees. By

opening up new career paths and new opportunities, NERI

will be able to retain and support staff members who want to

broaden their experience or grow into new responsibilities.

NERI: Committed to Leading-Edge Computer Training

Computer hardware and software continually evolve, and NERI has

long been committed to helping its staff keep pace with an in-house

computer training program. This program has played a vital role in

keeping NERI employees well-versed in current technology and practices,

helping to keep staff at the top of the class when competing for research and

scientific business opportunities.

For the past decade, NERI’s computer training program has been led by

Michael Maurao. An example of the program’s strengths is its support of

NERI’s industry-leading data management system software, ADEPT. Maurao

and his team have developed a series of courses aimed at those people who

use the system the most: NERI’s data managers. Each new data manager

participates in a Data Management Certification Program composed of various

classes taught by several different employees with past or present experience

with ADEPT.

Many of the courses are interactive and require class participants to immerse

themselves in the role of a data manager and they thus experience ADEPT

on a first-hand basis. Because those teaching the courses have had such deep

experience with the system, new data managers are presented with living

resources to help guide them on the path of certification.

Many other types of courses are available as well, some required, others

available as options to any staff member interested in honing existing skills or

learning new software tools and programs. NERI’s commitment to computer

training is one reason it is so highly-regarded in the research community, and

a reason its staff retention rates are so high.

NERI a Major Presence at AUA MeetingStaff from NERI’s Institute forEpidemiology will give seven presen-tations at the 2010 AmericanUrological Association (AUA) AnnualMeeting, to be held in San Franciscothis year. The Annual Meeting isbilled as “the world’s largest gather-ing of urologists and researchers.” It is a key part of the AUA’s ongoingmission to further urological healthcare through continuing educationprograms and presentation of the latest research to its over 16,000members.

The seven presentations draw on threeimportant research studies developedand led by NERI investigators: theMassachusetts Male Aging Study; the Boston Area Community HealthSurvey; and the HypogonadismScreener Development Project.

In addition, one of the presentationswill feature an analysis of the Third National Health and NutritionExamination Survey. Three of theseven presentations were selected as podium presentations and coverthe following topics: erectile dysfunc-tion as a predictor of cardiovascular disease; nocturia as a marker ofincreased mortality risk; and urologicpain symptoms.

NERI Leads in SBIR GrantsA recent ranking of companies mostsuccessful in being awarded SmallBusiness Innovation Research (SBIR)Phase II grants from the NationalInstitutes of Health reveals that NERIwas #2 in the nation for the period1992-2005, a testament to NERI’scommitment to high-quality researchand dissemination of research findings.
