Beneficiaries' perspectives on improved oral health and its mediators after Medicaid expansion in Michigan: a mixed methods study.

OBJECTIVE: To investigate self-reported improved oral health and its mediators, and job-related outcomes, of Medicaid expansion beneficiaries in Michigan. METHODS: This cross-sectional mixed-methods study of adult "Healthy Michigan Plan" (HMP) Medicaid expansion beneficiaries included qualitative interviews with a convenience sample of 67 beneficiaries enrolled for ≥6 months, a stratified random sample survey of 4,090 beneficiaries enrolled for ≥12 months; and Medicaid claims data. We examined unadjusted associations between demographic variables and awareness of dental coverage, self-reported dental care access, dental visits, and self-reported oral health; and between improved oral health and job seeking and job performance. Multivariate analysis examined factors associated with self-reported oral health improvement, adjusting for sociodemographic characteristics, prior health insurance, and having at least one dental visit claim. RESULTS: Among surveyed beneficiaries, 60 percent received ≥1 dental visit and 40 percent reported improved oral health. Adjusted odds ratios (aOR) for improved oral health were higher for African-American beneficiaries [aOR = 1.61; confidence interval (CI) = 1.28-2.03] and those previously uninsured for ≥12 months (aOR = 1.96; CI = 1.58-2.43). Beneficiaries reporting improved oral health were more likely to report improved job seeking (59.9 percent vs 51 percent; P = 0.04) and job performance (76.1 percent vs 65.0 percent; P < 0.001) due to HMP. Interviewees described previously unmet oral health needs, and treatments that improved oral health, functioning, appearance, confidence, and employability. CONCLUSION: Michigan's Medicaid expansion contributed to self-reported improved oral health, which was associated with improved job outcomes. Policymakers should consider the importance of Medicaid dental coverage in reducing oral health disparities and improving the health and socioeconomic well-being of low-income adults and communities when considering this optional benefit.

Self-Reported Health Status Improved For Racial And Ethnic Minority Groups After Michigan Medicaid Expansion.

Addressing health inequities for racial and ethnic minority populations is challenging. After passage of the Affordable Care Act, Michigan launched its Healthy Michigan Plan, which expanded Medicaid eligibility in the state. Our evaluation of the expansion provided the opportunity to study its impact on racial and ethnic minority groups, including Arab American and Chaldean American enrollees, an understudied population. Using data from telephone surveys collected in 2016, 2017, and 2018, we conducted an analysis to study the plan's impact on access to a regular source of care and health status among racial and ethnic minority groups. More than 90 percent of respondents of all racial and ethnic groups reported having a regular source of care after plan enrollment compared with 74.4 percent before enrollment. Respondents who identified as non-Hispanic White, African American, and Hispanic reported improvements in health status after plan enrollment. Our study demonstrates the potential of health insurance access to narrow health inequities between racial and ethnic groups.

Examination of Changes in Health Status Among Michigan Medicaid Expansion Enrollees From 2016 to 2017.

Importance: Evidence about the health benefits of Medicaid expansion has been mixed and has largely come from comparing expansion and nonexpansion states. Objective: To examine the self-reported health of enrollees in Michigan's Medicaid expansion, the Healthy Michigan Plan (HMP), over time. Design, Setting, and Participants: A telephone survey from January 1 to October 31, 2016 (response rate, 53.7%), and a follow-up survey from March 1, 2017, to January 31, 2018 (response rate, 83.4%), were conducted in Michigan, which expanded Medicaid in 2014 through a Section 1115 waiver permitting state-specific modifications. Four thousand ninety HMP beneficiaries aged 19 to 64 years with at least 12 months of HMP coverage and at least 9 months in a Medicaid health plan were eligible to participate. Data were analyzed from April 1 to November 30, 2018. Main Outcomes and Measures: Surveys measured demographic characteristics and health status. Analyses included weights for sampling probability and nonresponse. Comparisons between 2016 and 2017 included those who responded to both surveys (n = 3097). Results: Of the 3097 respondents to the 2017 follow-up survey, 2388 (77.1%) were still enrolled in HMP (current enrollees) and 709 (22.9%) were no longer enrolled when surveyed (former enrollees). Among all follow-up respondents, a weighted 37.5% (95% CI, 35.3%-39.9%) were aged 19 to 34 years, 34.0% (95% CI, 31.8%-36.2%) were aged 35 to 50 years, and 28.5% (95% CI, 26.7%-30.3%) were aged 51 to 64 years; 53.0% (95% CI, 50.8%-55.3%) were female. Respondents who reported fair or poor health decreased from 30.7% (95% CI, 28.7%-32.8%) in 2016 to 27.0% (95% CI, 25.1%-29.0%) in 2017 (adjusted odds ratio [AOR], 0.66 [95% CI, 0.53-0.81]; P < .001), with the largest decreases observed in respondents who were non-Hispanic black (from 31.5% [95% CI, 27.1%-35.9%] in 2016 to 26.0% [95% CI, 21.9%-30.1%] in 2017; P = .009), from the Detroit metropolitan area (from 30.7% [95% CI, 27.0%-34.4%] in 2016 to 24.9% [95% CI, 21.6%-28.3%] in 2017; P = .001), and with an income of 0% to 35% of the federal poverty level (from 37.6% [95% CI, 34.2%-40.9%] in 2016 to 32.3% [95% CI, 29.1%-35.5%] in 2017; P < .001). From 2016 to 2017, the mean number of days of poor physical health in the past month decreased significantly from 6.9 (95% CI, 6.5-7.4) to 5.7 (95% CI, 5.3-6.0) (coefficient, -6.10; P < .001), including among current (from 7.0 [95% CI, 6.5-7.5] to 5.6 [95% CI, 5.1-6.0]; P < .001) and former (from 6.8 [95% CI, 5.9-7.7] to 5.8 [95% CI, 5.0-6.7]; P = .02) enrollees, those with 2 or more chronic conditions (from 9.9 [95% CI, 9.3-10.6] to 8.5 [95% CI, 7.8-9.1]; P < .001), across all age groups (19-34 years, from 4.3 [95% CI, 3.7-4.9] to 3.0 [95% CI, 2.5-3.5]; P < .001; 35-50 years, from 8.2 [95% CI, 7.3-9.0] to 6.9 [95% CI, 6.1-7.7]; P = .002; 51-64 years, from 9.0 [95% CI, 8.2-9.8] to 7.6 [95% CI, 6.9-8.3]; P = .001), and among non-Hispanic white (from 7.5 [95% CI, 7.0-8.1] to 6.1 [95% CI, 5.6-6.6]; P < .001) and black (from 5.9 [95% CI, 5.1-6.8] to 4.4 [95% CI, 3.6-5.1]; P < .001) respondents. No changes in days of poor mental health or usual activities missed owing to poor physical or mental health were observed. Conclusions and Relevance: These findings suggest that HMP enrollees in Michigan have experienced improvements in self-reported health over time, including minority groups with a history of health disparities and enrollees with chronic health conditions.

Association of Medicaid Expansion With Enrollee Employment and Student Status in Michigan.

Importance: Medicaid community engagement requirements (work, school, job searching, or community service) are being implemented by several states for the first time, but the association of Medicaid coverage with enrollees' employment and school attendance is unclear. Objective: To assess longitudinal changes in enrollees' employment or student status after Michigan's Medicaid expansion. Design, Setting, and Participants: This survey study included 4090 nonelderly, adult Healthy Michigan Plan enrollees from March 1, 2017, to January 31, 2018. Main Outcomes and Measures: Self-reported employment or student status. Proportionate sampling was stratified by income and geographic region. Mixed-effects regression models with time indicators were used to assess longitudinal changes in the proportion of enrollees who were employed or students. Results: The response rate for the initial survey was 53.7% and for the follow-up survey was 83.4%. Of the 3104 respondents to the 2017 follow-up survey (mean [SD] age in 2017, 42.2 [13.0] years; 1867 [53.0%] female), 54.3% were employed or students in 2016, and this number increased to 60.0% in 2017 (percentage point change, 5.7; P < .001). Non-Hispanic black enrollees had significantly larger gains in employment or student status compared with non-Hispanic white enrollees (percentage point change, 10.7 vs 3.5; P = .02). Changes in employment or student status were not associated with improved health status. Conclusions and Relevance: Employment or student status increased from 2016 to 2017 among Michigan Medicaid expansion enrollees. These findings provide information about whether Medicaid coverage or community engagement requirements are best to promote the desired outcomes of employment and student status.

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.

Engagement with Health Risk Assessments and Commitment to Healthy Behaviors in Michigan's Medicaid Expansion Program.

BACKGROUND: Health risk assessments (HRAs) and healthy behavior incentives are increasingly used by state Medicaid programs to promote enrollees' health. OBJECTIVE: To evaluate enrollee experiences with HRAs and healthy behavior engagement in the Healthy Michigan Plan (HMP), a state Medicaid expansion program. DESIGN: Telephone survey conducted in Michigan January-October 2016. PARTICIPANTS: A random sample of HMP enrollees aged 19-64 with ≥ 12 months of enrollment, stratified by income and geographic region. MAIN MEASURES: Self-reported completion of an HRA, reasons for completing an HRA, commitment to a healthy behavior, and choice of healthy behavior. KEY RESULTS: Among respondents (N = 4090), 49.3% (95% CI 47.3-51.2%) reported completing an HRA; among those with a primary care provider (PCP) (n = 3851), 85.2% (95% CI 83.5-86.7%) reported visiting their PCP during the last 12 months. Most enrollees having a recent PCP visit reported discussing healthy behaviors with them (91.1%, 95% CI 89.6-92.3%) and were more likely to have completed an HRA than enrollees without a recent PCP visit (52.7%, 95% CI 50.5-52.8% vs. 36.2%, 95% CI 31.7-41.1%; p < 0.01). Among enrollees completing an HRA, nearly half said they did it because their PCP suggested it (45.9%, 95% CI 43.2-48.7%), and most reported it helped their PCP understand their health needs (89.7%). Awareness of financial incentives was limited (28.1%, 95% CI 26.3-30.0%), and very few reported it as the primary reason for HRA completion (2.5%, 95% CI 1.8-3.4%). Most committed to a healthy behavior (80.7%, 95% CI 78.5-82.8%), and common behaviors chosen were nutrition/diet (57.2%, 95% CI 54.2-60.2%) and exercise/activity (52.6%, 95% CI 49.5-55.7%). CONCLUSIONS: In the Healthy Michigan Plan, PCPs appeared influential in enrollees' completion of HRAs and healthy behavior engagement, while knowledge of financial incentives was limited. Additional study is needed to understand the relative importance of financial incentives and PCP engagement in impacting healthy behaviors in state Medicaid programs.

Primary Care, Health Promotion, and Disease Prevention with Michigan Medicaid Expansion.

BACKGROUND: Medicaid expansion in Michigan, known as the Healthy Michigan Plan (HMP), emphasizes primary care and preventive services. OBJECTIVE: Evaluate the impact of enrollment in HMP on access to and receipt of care, particularly primary care and preventive services. DESIGN: Telephone survey conducted during January-November 2016 with stratified random sampling by income and geographic region (response rate = 53.7%). Logistic regression analyses accounted for sampling and nonresponse adjustment. PARTICIPANTS: 4090 HMP enrollees aged 19-64 with ≥ 12 months of HMP coverage MAIN MEASURES: Surveys assessed demographic factors, health, access to and use of health care before and after HMP enrollment, health behaviors, receipt of counseling for health risks, and knowledge of preventive services' copayments. Utilization of preventive services was assessed using Medicaid claims. KEY RESULTS: In the 12 months prior to HMP enrollment, 33.0% of enrollees reported not getting health care they needed. Three quarters (73.8%) of enrollees reported having a regular source of care (RSOC) before enrollment; 65.1% of those reported a doctor's office/clinic, while 16.2% reported the emergency room. After HMP enrollment, 92.2% of enrollees reported having a RSOC; 91.7% had a doctor's office/clinic and 1.7% the emergency room. One fifth (20.6%) of enrollees reported that, before HMP enrollment, it had been over 5 years since their last primary care visit. Enrollees who reported a visit with their primary care provider after HMP enrollment (79.3%) were significantly more likely than those who did not report a visit to receive counseling about health behaviors, improved access to cancer screening, new diagnoses of chronic conditions, and nearly all preventive services. Enrollee knowledge that some services have no copayments was also associated with greater utilization of most preventive services. CONCLUSIONS: After enrolling in Michigan's Medicaid expansion program, beneficiaries reported less forgone care and improved access to primary care and preventive services.

Diagnosis and Care of Chronic Health Conditions Among Medicaid Expansion Enrollees: a Mixed-Methods Observational Study.

BACKGROUND: It is uncertain how Medicaid expansion under the Affordable Care Act influences the diagnosis of chronic health conditions, and the care and health of enrollees with chronic conditions. OBJECTIVE: Describe the prevalence of new and pre-existing chronic health conditions among Medicaid expansion enrollees. Examine whether perceived changes in specific types of access and self-rated health status differed between enrollees with chronic conditions and those without. Examine how gaining Medicaid coverage affected chronic disease management and well-being. DESIGN: Mixed-methods study including a telephone survey and semi-structured interviews. SETTING: Michigan's Medicaid expansion, the "Healthy Michigan Plan" (HMP). PARTICIPANTS: 4090 survey respondents (response rate 54%) with ≥ 12 months HMP enrollment and 67 interviewees with ≥ 6 months enrollment. MAIN MEASURES: Self-reported chronic condition diagnoses, changes in physical/mental health, and healthcare access. Descriptive survey data were adjusted for survey design and nonresponse. Semi-structured interview questions about how gaining HMP coverage led to changes in health status. KEY RESULTS: Among enrollees, 68% had a self-reported diagnosis of a chronic health condition; 42% of those were newly diagnosed since HMP enrollment. In multivariable models, enrollees with chronic conditions were significantly more likely to report improved physical (adjusted odds ratio (aOR) 1.70, 95% CI (1.40, 2.07)) and mental health (aOR 1.75, (1.43, 2.15)) since HMP enrollment than enrollees without chronic conditions. Among enrollees with chronic conditions, the strongest predictors of improvements in health were having seen a primary care physician, improved mental health care access, and improved medication access. Interviewees with chronic conditions described how increased access to health care led to improvements in both physical and mental health. CONCLUSIONS: Enrollees with expanded Medicaid coverage commonly reported detection of previously undiagnosed chronic conditions. Perceived health status and access improved more often among enrollees with chronic health conditions. Improved access was associated with improved physical and mental health among this vulnerable group.

Changes in Health and Ability to Work Among Medicaid Expansion Enrollees: a Mixed Methods Study.

BACKGROUND: Michigan expanded Medicaid under the Affordable Care Act (Healthy Michigan Plan [HMP]) to improve the health of low-income residents and the state's economy. OBJECTIVE: To understand HMP's impact on enrollees' health, ability to work, and ability to seek employment DESIGN: Mixed methods study, including 67 qualitative interviews and 4090 computer-assisted telephone surveys (response rate 53.7%) PARTICIPANTS: Non-elderly adult HMP enrollees MAIN MEASURES: Changes in health status, ability to work, and ability to seek employment KEY RESULTS: Half (47.8%) of respondents reported better physical health, 38.2% better mental health, and 39.5% better dental health since HMP enrollment. Among employed respondents, 69.4% reported HMP helped them do a better job at work. Among out-of-work respondents, 54.5% agreed HMP made them better able to look for a job. Among respondents who changed jobs, 36.9% agreed HMP helped them get a better job. In adjusted analyses, improved health was associated with the ability to do a better job at work (aOR 4.08, 95% CI 3.11-5.35, p < 0.001), seek a job (aOR 2.82, 95% CI 1.93-4.10, p < 0.001), and get a better job (aOR 3.20, 95% CI 1.69-6.09, p < 0.001), but not with employment status (aOR 1.08, 95% CI 0.89-1.30, p = 0.44). In interviews, several HMP enrollees attributed their ability to get or maintain employment to improved physical, mental, and dental health because of services covered by HMP. Remaining barriers to work cited by enrollees included older age, disability, illness, and caregiving responsibilities. CONCLUSIONS: Many low-income HMP enrollees reported improved health, ability to work, and job seeking after obtaining health insurance through Medicaid expansion.
