Health Risk Assessments in Michigan's Medicaid Expansion: Early Experiences in Primary Care.

INTRODUCTION: Michigan is one of 3 states that have implemented health risk assessments for enrollees as a feature of its Medicaid expansion, the Healthy Michigan Plan. This study describes primary care providers' early experiences with completing health risk assessments with enrollees and examines provider- and practice-level factors that affect health risk assessment completion.

METHODS: All primary care providers caring for ≥12 Healthy Michigan Plan enrollees (n=4,322) were surveyed from June to November 2015, with 2,104 respondents (55.5%). Analyses in 2016-2017 described provider knowledge, attitudes, and experiences with the health risk assessment early in Healthy Michigan Plan implementation; multivariable analyses examined relationships of provider- and practice-level characteristics with health risk assessment completion, as recorded in state data.

RESULTS: Of the primary care provider respondents, 73% found health risk assessments very or somewhat useful for identifying and discussing health risks, although less than half (47.2%) found them very or somewhat useful for getting patients to change health behaviors. Most primary care provider respondents (65.3%) were unaware of financial incentives for their practices to complete health risk assessments. Nearly all primary care providers had completed at least 1 health risk assessment. The mean health risk assessment completion rate (completed health risk assessments/number of Healthy Michigan Plan enrollees assigned to that primary care provider) was 19.6%; those who lacked familiarity with the health risk assessment had lower completion rates.

CONCLUSIONS: Early in program implementation, health risk assessment completion rates by primary care providers were low and awareness of financial incentives limited. Most primary care provider respondents perceived health risk assessments to be very or somewhat useful in identifying health risks, and about half of primary care providers viewed health risk assessments as very or somewhat useful in helping patients to change health behaviors.
