Is Medication Adherence really a problem?

A PubMed search for: “Medication Adherence”

returned 5959 articles

Low adherence with prescribed treatments is very common. Typical adherence rates for

prescribed medications are about 50% with a range from 0% to over 100% - Sackett 1979

Even among groups of people thought to be most responsible (Company Executives,

Healthcare professionals, etc.), good medication adherence is barely above 50% - Burton

2010

“ Poor adherence to medication regimens accounts for substantial worsening of disease,

death, and increased health care costs in the United States. Of all medication-related hospital admissions in the United States, 33 to 69 percent are due to poor medication adherence, with a resultant cost of approximately $100 billion a year.” – Osterberg 2005

It’s a Win-Win situationThe Healthcare industry (Insurers, Hospitals,

etc) saves moneyPatients have better health outcomes (and less

hospitalizations)

Why Target Teenagers?

You Can’t Teach an Old Dog New Tricks

Actually you can, but it’s much more effective to teach a Young one

Adolescence, especially late adolescence, is associated with low medication adherence

One study looking at transplant recipients found that the rate of medication non-adherence among adolescent recipients is approximately 4 times higher than that among adult recipients – Fredericks

Why?

Teenage years are associated with…

Independence

Less Supervision

Less Guidance

Multiple Studies have shown a significant correlation between increased independence and decreased adherence in adolescents – Sawyer, Fredericks, Kovacs

RebellionConcerns about poor adherence in adolescents often result in protective parent behaviors, such as constant reminders to take their medication.

While parents hope the reminders will promote better adherence, their prompts are often interpreted by young people as unwarranted “nagging”, which often if not always has the opposite effect.

Why Target Newly Independent Teenagers?

“Medication adherence was significantly poorer in the newly transitioned cohort in comparison with pediatric and adult cohorts” - Fredericks

“Poorer adherence [in adolescents] was significantly related to older age” -

Fredericks

“Ages 17 – 19 are associated with the most amount of time being

noncompliant” – Kovacs

Newly Independent Teenagers have the worst medication adherence rates

“The developmental characteristics associated with adolescence, including the development of autonomy from family, assimilation with peers, separation from parents, and poorly developed abstract thinking and understanding of long-term consequences of present actions, are often difficult to balance with the behaviors required for optimal medication adherence.” - Fredericks

Prepare all you can, eventually they all do it…

Habit interventions gain power when they are applied during naturally occurring periods of change in [peoples’] lives - Verplanken 2006

Improving Medication Adherence

First we must discover WHY adherence is low

In addition to the teenager specific reasons…

Common reasons patients give include:

Adverse Effects

Poor / Confusing InstructionsForgetfulness

“Don’t Need It”

Too Expensive

Examples of Interventions that attempt to address 1 or more of these include…

Information Campaigns

“Information campaigns that successfully convey information do not necessarily change consumers’ behaviors.” – Verplanken

Several studies showed that “telling people about adverse effects of their medications did not affect their use of the medications.” - Haynes

The problem with these campaigns is the Disconnection between changing minds and changing behavior

SMS-based Interventions

Modest improvement in adherence

Addresses “Forgetfulness”

Limited to Simple Reminders

Patient compliance with antihypertensive medications has previously been boosted by using battery-powered radiofrequency identification (RFID) tags embedded in the lids of pill bottles or in medication blister packs. These RFID tags record each time the bottle is opened or a pill is popped from the blister pack. Now, pharmaceutical companies are pushing the boundaries further by producing ‘robo-pills’ containing tiny microchips. The microchips send a text message to patients’ phones if they fail to take their medication and are said to increase compliance by 30–80% - Roberts

Newer Approaches

Pill ‘n’ chipstackles non-compliance

In fact, many different interventions have been attempted

– More instruction for patients, e.g. verbal, written, or visual material

– Counseling about the patients’ target disease, the importance of therapy and compliance with therapy, the possible side-effects, patient empowerment, couple-focused therapy to increase social support

– Automated telephone, computer-assisted patient monitoring and counseling

– Manual telephone follow-up– Family intervention – Various ways to increase the convenience

of care, e.g. provision at the worksite or at home

– Involving patients more in their care through self-monitoring of their blood pressure

– Reminders, e.g. programmed devices and tailoring the regimen to daily habits

– Special ’reminder’ pill packaging

– Dose-dispensing units of medication and medication charts

– Appointment and prescription refill reminders

– Reinforcement or rewards for both improved adherence and treatment response, e.g. reduced frequency of visits and partial payment for blood pressure monitoring equipment

– Different medication formulations, such as tablet versus syrup

– Crisis intervention conducted when necessary, e.g. for attempted suicide, aggressive and destructive behavior

– Direct observation of treatments (DOTS) by health workers or family members

– Lay health mentoring– Augmented pharmacy services– Psychological therapy, e.g. cognitive

behavior therapy, multisystemic therapy– Mailed communications– Group meetings

…yet we continue to search for a better solution

Why iPhone?

For long-term treatments, no simple intervention, and only some complex ones, led to improvements in health outcomes.

They included combinations of more convenient care, information, counseling, reminders, self-monitoring, reinforcement, family therapy, psychological therapy, mailed communications, crisis intervention, manual telephone follow-up, and other forms of additional supervision or attention. – Haynes

The solution is complex…

The iPhone can do many of these things and more…

• Social (Facebook / Twitter / Other integration)• Reminders (Notifications)• Communicate with other devices (Bluetooth,

Wi-Fi)• Information (Internet)• And much more…

It’s with them CONSTANTLY

Keys to Success

For an iPhone App to improve Medication Adherence

BJ Fogg’s Behavior Model

Trigger

Make the iPhone DO SOMETHING at the right time

• Send push / local notifications• Add calendar events with alarms• SMS• MMS• CALL• (Email)

Motivate

Make the patient WANT to take their medication

• Utilize Game MechanicsImagine piloting a nanobot through the bodies of fictional cancer patients, destroying

cancer cells in your path, battling bacterial infections, and managing side effects. This is the Re-Mission game, developed for adolescents and young people with cancer, that hopelab.org believe will help them develop a positive attitude, learn about their cancer and has been shown to improve adherence. – Roberts

• Competition• Social

Ability

• Cheap / FREE• SIMPLE• Quick and easy to set up• Automate whatever possible• Consistency

In Conclusion…

Medication Adherence is a problem

Teenagers leaving home are especially at risk

They’re also at a point where interventions are most effective

A complex solution is needed

The iPhone has the capabilities to meet most of these needs and be successful

Thanks!
