Objective
Determine whether performance and
improvement over time on three
antidepressant medication management
(AMM) measures in HEDIS differ by how
health plans organize, finance, and
administer behavioral health care.
Context
• HEDIS AMM measures overall are low
compared to other HEDIS measures
• AMM measures are generally not
improving over time (unlike other measures)
• Most privately insured individuals are in
managed care
• Need to learn what health plan features are
associated with better performance
HEDIS Antidepressant Medication Management
(AMM) Measures
• Effective Acute Phase Treatment
• Effective Continuation Phase Treatment
• Optional Practitioner Contact
Health Plan Domains
• Organization
• Provider
• Consumer
Research Design Overview
• Linkage of two datasets: Brandeis
Health Plan Survey and NCQA’s HEDIS
and CAHPS data
• Analyzing relationships between key
plan characteristics and performance on
AMM measures
• Both cross-sectional and longitudinal
(1999 to 2003) analyses
Data and Sample
Brandeis Survey: 2003 health plan survey on alcohol,
drug, and mental health services. Nationally representative,
linked to 60 Community Tracking Study market areas. N =
368 (812 products). Response rate = 83%.
NCQA: 2003 health plan participants in HEDIS.
N = 300.
Study Sample: All health plans present in both datasets.
N = 183 plans, covering 361 HMO and POS products.
Analytic Approach
• Describe health plans’ 2003 performance
on the three HEDIS AMM measures and
relationship with key plan characteristics
• Conduct multivariate analysis to control for
effects of other health plan and market
variables.
Effective Acute Phase Treatment
Percentage of eligible members who received
effective acute phase treatment after a new
episode of depression by remaining on
antidepressant medication during the first 12
weeks following diagnosis
• Mean
= 59.5%
• 10th percentile = 53.6%
• 90th percentile = 66.2%
Effective Continuation Phase Treatment
Percentage of members who received effective
continuation phase treatment by remaining on
antidepressant medication continuously in the 6
months after the initial diagnosis and treatment.
• Mean
= 42.9%
• 10th percentile = 37.8%
• 90th percentile = 50.5%
Optimal Practitioner Contact
Percentage of eligible members who received at
least 3 follow-up office visits with PCP or mental
health provider in the 12-week acute treatment
phase after diagnosis of depression and
prescription of antidepressant medication.
• Mean
• 10th percentile
• 90th percentile

Conclusions
• Patient cost sharing and choice of
SSRIs affect HEDIS AMM
performance
• Individual feedback to providers helps
• Some approaches geared towards
improving quality seem to do so
(disease management)
• Others (e.g., PCP/BH coordination)
raise more questions
