John Billings: Applying predictive risk approaches and models effectively

June, 2012

New York University Robert F. Wagner Graduate School of Public Service

APPLYING PREDICTIVE RISK APPROACHES

AND MODELS EFFECTIVELY

WHAT I’M GOING TO TALK ABOUT

• What not to do

• What to try to do

• An example of how we almost got it right, but in the end, not so much

WHAT NOT TO DO

• Don’t do it the way we do it in the U.S.

WHAT NOT TO DO

• Don’t do it the way we do it in the U.S. – Model development limitations

WHAT NOT TO DO

• Don’t do it the way we do it in the U.S. – Model development limitations – Intervention design flaws

WHAT NOT TO DO

• Don’t do it the way we do it in the U.S. – Model development limitations – Intervention design flaws – Intervention implementation flaws

WHAT NOT TO DO

• Don’t do it the way you do it in the U.K. [With noteable exceptions]

WHAT NOT TO DO

• Don’t do it the way you do it in the U.K. – Model development limitations

[With noteable exceptions]

WHAT NOT TO DO

• Don’t do it the way you do it in the U.K. – Model development limitations – Intervention design flaws

WHAT NOT TO DO

• Don’t do it the way you do it in the U.K. – Model development limitations – Intervention design flaws – Intervention implementation flaws

WHAT TO DO

• Model development limitations – Predict risks of expensive things you think you do something about

WHAT TO DO

• Model development limitations – Predict risks of expensive things you think you do something about – Make sure your data base has most of the key risk factors

WHAT TO DO

• Model development limitations – Predict risks of expensive things you think you do something about – Make sure your data base has most of the key risk factors – Recognize the trade-offs between model accuracy and sensitivity

WHAT TO DO

• Intervention design flaws – Design the intervention after the risk model has been developed

WHAT TO DO

• Intervention design flaws – Design the intervention after the risk model has been developed – Use data from model development to help design the intervention

WHAT TO DO

• Intervention design flaws – Design the intervention after the risk model has been developed – Use data from model development to help design the intervention – Recognize you are probably going to need more information

WHAT TO DO

• Intervention design flaws – Design the intervention after the risk model has been developed – Use data from model development to help design the intervention – Recognize you are probably going to need more information – Get the incentives right

WHAT TO DO

• Intervention implementation flaws – Roll it out in at least quasi-experimental mode

WHAT TO DO

• Intervention implementation flaws – Roll it out in at least quasi-experimental mode – Track “dosage” levels (who does what to whom and how)

WHAT TO DO

• Intervention implementation flaws – Roll it out in at least quasi-experimental mode – Track “dosage” levels (who does what to whom and how) – Avoid enrollment criteria “leakage”

WHAT TO DO

• Intervention implementation flaws – Roll it out in at least quasi-experimental mode – Track “dosage” levels (who does what to whom and how) – Avoid enrollment criteria “leakage” – Evaluate impact of the intervention as rigorously as possible

A SOMEWHAT IDEALIZED SUGGESTED APPROACH TO PREDICTIVE RISK MODELING AND EFFECTIVE IMPLEMENTATION

Step 1: See if you can develop a predictive model to identify patients with risks that you think you can do something about

Step 2: Learn as much as you can about these patients to help in designing the intervention(s)

- Use available administrative data

- Use available administrative data - Apply predictive model to real patients – interview a sample of

these patients (and their providers, families, caregivers, etc.)

THEN GET SOME SMART PEOPLE IN THE ROOM AND DESIGN THE INTERVENTION

Step 3: Implement/evaluate pilot projects based on this information

- Pilot with a quasi-experimental design (intervention/control) - Conduct “formative” evaluation during early phases of

implementation - Assess impact of intervention on outcomes/utilization

Step 4: Disseminate results/Scale it up if it works

HOW WE ALMOST GOT IT RIGHT, BUT THEN NOT SO MUCH

• NY Medicaid fee-for-service patients • Adult disabled • Not on Medicare (non-duals)

• Not in residential care

NEW YORK MEDICAID CHRONIC ILLNESS DEMONSTRATION PROJECT

• Used five years of historic paid claims records

• Predicted hospitalization in next 12 months

• Ran quarterly

Index Quarters

Year 4 Year 5 Year 3 Year 2 Year 1 Q1 Q2 Q3 Q4

• Prior hospital utilization by type – Number of admissions – Intervals/recentness

• Prior emergency department utilization • Prior outpatient utilization/claims

– By type of visit (primary care, specialty care, substance abuse, etc) – By service type (transportation, home care, personal care, etc)

• Diagnostic information from prior hospital and outpatient utilization – Chronic conditions (type/number) – Hierarchical grouping (Hierarchical Condition Categories - HCCs)

• Prior costs – Pharmacy – DME – Total

• Characteristics of the predominant hospital and primary care provider • Patient characteristics: Age, gender, race/ethnicity, eligibility category

THEN GET SOME SMART PEOPLE IN THE ROOM AND DESIGN THE INTERVENTION

SO WHAT’S IT GOING TO TAKE?

• Multi-disciplinary approach for individualized needs assessment and care planning for participating patients

• Integrated/organized/coordinated health care delivery system – Primary care – Specialty care – Substance abuse/mental health services – Inpatient care – Etc, etc

• Integrated/organized/coordinated health care delivery system and linkage to social service delivery system – Primary care – Specialty care – Substance abuse/mental health services – Inpatient care – Community based social support programs/resources – Supportive housing for many – Etc, etc, etc, etc

• Integrated/organized/coordinated health care delivery system and linkage to social service delivery system

• Some sort of care/service-coordinator/arranger – With a reasonable caseload size – With a clear mission (to improve health and to reduce costs)

• Some sort of care/service-coordinator/arranger

• Core IT and analytic support capacity to… – Track patient utilization in close to real time – Mine administrative data and target interventions/outreach – Provide analysis of utilization patterns

• Identify trends/problems to continuously re-design intervention strategies • Provide feed-back to providers on performance

– Hospital admission rates – ED visit rates – Adherence to evidence based practice standards

– Support effective use of electronic medical records where available

• Core IT and analytic support capacity

• Ability to provide real time support at critical junctures – ED visit - prevention of “social admissions” – Hospital discharge - effective community support/management planning – Patient initiated - help for an emerging crisis

• Ability to provide real time support at critical junctures

• Incentives/reimbursement policies to encourage and reward “effective and cost efficient care” – Hospitals must have a shared interest in avoiding admissions – Reimbursement rates for OP services need to be related to their costs – Costs of social support need to be recognized – [No new money – any new/augmented services offset by IP savings]

• Ability to provide real time support at critical junctures

• Incentives/reimbursement policies to encourage and reward “effective and cost efficient care”

• Core IT and analytic support capacity ???

• Ability to provide real time support at critical junctures ???

• Incentives/reimbursement policies to encourage and reward “effective and cost efficient care” ???

• NY State legislature authorized $20M demonstration • After a competitive procurement process that took 13

months to implement, awards for 7 pilots March, 2009 • NYC sites had a goal of 500 patients, non-NYC 250 • Program provides $250/month for care coordination and

a “shared savings pool” • July, 2009: One pilot dropped out • August, 2009: Enrollment began in 6 remaining pilots • October, 2009 – July, 2011: sites received quarterly

enrollment refreshments

• Federal government would not allow randomization of patients into the initiative – All patients in a geographic area must have access to same set of

services unless obtain a “waiver” (18 months and politically “fraught”)

services unless obtain a “waiver” (18 months and politically “fraught”) – Brilliant solution: randomize zip codes (and tell federal government that

being implement only some areas of the state)

• The $48 billion NY Medicaid agency (equivalent in revenue to #57 on Fortune 500 list of U.S. companies) had no funds authorized to conduct an evaluation

– Local philanthropy provided limited funding – But not enough to survey patients or contact control group

• Sites had enormous difficulty locating patients for enrollment – Found and enrolled only 25% of eligible patients – State dropped risk score cut-off from 50 to 40 and finally to 30

• At least in part inspired by CIDP, US national health reform legislation (Affordable Care Act, aka “Obama Care”), authorized new “Medicaid Health Home Program”

• Federal government provides 90%-10% funding match for care coordination initiatives like CIDP for patients with multiple chronic conditions

• In New York, the 2,000+ CIDP program folded into the new Health Home initiative, with plans to ultimately expand to 700,000 patients

• Preliminary evaluation of CIDP expected sometime in next 12 months

WHAT NOT TO DO

WHAT TO DO

• Intervention implementation flaws – Roll it out in at least quasi-experimental mode – Track “dosage” levels (who does what to whom and how) – Avoid enrollment criteria “leakage” – Evaluate impact of the intervention as rigorously as possible
