Prescriptions for Buprenorphine in Michigan Following an Education Intervention.

Importance: Buprenorphine is an underused treatment for opioid use disorder (OUD) that can be prescribed in general medical settings. Founded in 2017, the Michigan Opioid Collaborative (MOC) is an outreach and educational program that aims to address clinician and community barriers to buprenorphine access; however, the association between the MOC and buprenorphine treatment is unknown. Objective: To evaluate the association between MOC service use and county-level temporal trends of density of buprenorphine prescribers and patients receiving buprenorphine. Design, Setting, and Participants: This cohort study exploited staggered implementation of MOC services across all Michigan counties. Difference-in-difference analyses were conducted by applying linear fixed-effects regression across all counties to estimate the overall association of MOC engagement with outcomes and linear regression for each MOC-engaged county separately to infer county-specific results using data from May 2015 to August 2020. Analyses were conducted from September 2021 to November 2023. Exposures: MOC engagement. Main Outcomes and Measures: County-level monthly numbers of buprenorphine prescribers and patients receiving buprenorphine (per 100 000 population). Results: Among 83 total counties, 57 counties (68.7%) in Michigan were engaged by MOC by 2020, with 3 (3.6%) initiating engagement in 2017, 19 (22.9%) in 2018, 27 (32.5%) in 2019, and 8 (9.6%) in 2020. Michigan is made up of 83 counties with a total population size of 9 990 000. A total of 5 070 000 (50.8%) were female, 1 410 000 (14.1%) were African American or Black, 530 000 (5.3%) were Hispanic or Latino, and 7 470 000 (74.7%) were non-Hispanic White. The mean (SD) value of median age across counties was 44.8 (6.4). The monthly increases in buprenorphine prescriber numbers in the preengagement (including all time points for nonengaged counties) and postengagement periods were 0.07 and 0.39 per 100 000 population, respectively, with the absolute difference being 0.33 (95% CI, 0.12-0.53) prescribers per 100 000 population (P = .002). The numbers of patients receiving buprenorphine increased by an average of 0.6 and 7.15 per 100 000 population per month in preengagement and postengagement periods, respectively, indicating an estimated additional 6.56 (95% CI, 2.09-11.02) patients receiving buprenorphine per 100 000 population (P = .004) monthly increase after engagement compared with before. Conclusions and Relevance: In this cohort study measuring buprenorphine prescriptions in Michigan over time, counties' engagement in OUD-focused outreach and clinician education services delivered by a multidisciplinary team was associated with a temporal increase in buprenorphine prescribers and patients receiving buprenorphine.

The Counseling Older Adults to Control Hypertension (COACH) trial: design and methodology of a group-based lifestyle intervention for hypertensive minority older adults.

The disproportionately high prevalence of hypertension and its associated mortality and morbidity in minority older adults is a major public health concern in the United States. Despite compelling evidence supporting the beneficial effects of therapeutic lifestyle changes on blood pressure reduction, these approaches remain largely untested among minority elders in community-based settings. The Counseling Older Adults to Control Hypertension trial is a two-arm randomized controlled trial of 250 African-American and Latino seniors, 60 years and older with uncontrolled hypertension, who attend senior centers. The goal of the trial is to evaluate the effect of a therapeutic lifestyle intervention delivered via group classes and individual motivational interviewing sessions versus health education, on blood pressure reduction. The primary outcome is change in systolic and diastolic blood pressure from baseline to 12 months. The secondary outcomes are blood pressure control at 12 months; changes in levels of physical activity; body mass index; and number of daily servings of fruits and vegetables from baseline to 12 months. The intervention group will receive 12 weekly group classes followed by individual motivational interviewing sessions. The health education group will receive an individual counseling session on healthy lifestyle changes and standard hypertension education materials. Findings from this study will provide needed information on the effectiveness of lifestyle interventions delivered in senior centers. Such information is crucial in order to develop implementation strategies for translation of evidence-based lifestyle interventions to senior centers, where many minority elders spend their time, making the centers a salient point of dissemination.
