Practice Facilitation and Peer Coaching for Uncontrolled Hypertension Among Black Individuals: A Randomized Clinical Trial.

Importance: Rural Black participants need effective intervention to achieve better blood pressure (BP) control. Objective: Among Black rural adults with persistently uncontrolled hypertension attending primary care clinics, to determine whether peer coaching (PC), practice facilitation (PF), or both (PCPF) are superior to enhanced usual care (EUC) in improving BP control. Design, Setting, and Participants: A cluster randomized clinical trial was conducted in 69 rural primary care practices across Alabama and North Carolina between September 23, 2016, and September 26, 2019. The participating practices were randomized to 4 groups: PC plus EUC, PF plus EUC, PCPF plus EUC, and EUC alone. The baseline EUC approach included a laptop for each participating practice with hyperlinks to participant education on hypertension, a binder of practice tips, a poster showing an algorithm for stepped care to improve BP, and 25 home BP monitors. The trial was stopped on February 28, 2021, after final data collection. The study included Black participants with persistently uncontrolled hypertension. Data were analyzed from February 28, 2021, to December 13, 2022. Interventions: Practice facilitators helped practices implement at least 4 quality improvement projects designed to improve BP control throughout 1 year. Peer coaches delivered a structured program via telephone on hypertension self-management throughout 1 year. Main Outcomes and Measures: The primary outcome was the proportion of participants in each trial group with BP values of less than 140/90 mm Hg at 6 months and 12 months. The secondary outcome was a change in the systolic BP of participants at 6 months and 12 months. Results: A total of 69 practices were randomized, and 1209 participants' data were included in the analysis. The mean (SD) age of participants was 58 (12) years, and 748 (62%) were women. In the intention-to-treat analyses, neither intervention alone nor in combination improved BP control or BP levels more than EUC (at 12 months, PF vs EUC odds ratio [OR], 0.94 [95% CI, 0.58-1.52]; PC vs EUC OR, 1.30 [95% CI, 0.83-2.04]; PCPF vs EUC OR, 1.02 [95% CI, 0.64-1.64]). In preplanned subgroup analyses, participants younger than 60 years in the PC and PCPF groups experienced a significant 5 mm Hg greater reduction in systolic BP than participants younger than 60 years in the EUC group at 12 months. Practicewide BP control estimates in PF groups suggested that BP control improved from 54% to 61%, a finding that was not observed in the trial's participants. Conclusions and Relevance: The results of this cluster randomized clinical trial demonstrated that neither PC nor PF demonstrated a superior improvement in overall BP control compared with EUC. However, PC led to a significant reduction in systolic BP among younger adults. Trial Registration: ClinicalTrials.gov Identifier: NCT02866669.

The design and rationale of a multicenter real-world trial: The Southeastern Collaboration to Improve Blood Pressure Control in the US Black Belt - Addressing the Triple Threat.

BACKGROUND: Impoverished African Americans (AA) with hypertension face poor health outcomes. PURPOSE: To conduct a cluster-randomized trial testing two interventions, alone and in combination, to improve blood pressure (BP) control in AA with persistently uncontrolled hypertension. METHODS: We engaged primary care practices serving rural Alabama and North Carolina residents, and in each practice we recruited approximately 25 AA adults with persistently uncontrolled hypertension (mean systolic BP >140 mmHg over the year prior to enrollment plus enrollment day BP assessed by research assistants ≥140/90 mmHg). Practices were randomized to peer coaching (PC), practice facilitation (PF), both PC and PF (PC + PF), or enhanced usual care (EUC). Coaches met with participants from PC and PC + PF practices weekly for 8 weeks then monthly over one year, discussing lifestyle changes, medication adherence, home monitoring, and communication with the healthcare team. Facilitators met with PF and PC + PF practices monthly to implement ≥1 quality improvement intervention in each of four domains. Data were collected at 0, 6, and 12 months. RESULTS: We recruited 69 practices and 1596 participants; 18 practices (408 participants) were randomized to EUC, 16 (384 participants) to PF, 19 (424 participants) to PC, and 16 (380 participants) to PC + PF. Participants had mean age 57 years, 61% were women, and 56% reported annual income <$20,000. LIMITATIONS: The PF intervention acts at the practice level, possibly missing intervention effects in trial participants. Neither PC nor PF currently has established clinical reimbursement mechanisms. CONCLUSIONS: This trial will fill evidence gaps regarding practice-level vs. patient-level interventions for rural impoverished AA with uncontrolled hypertension.

A community-engaged approach to understanding environmental health concerns and solutions in urban and rural communities.

BACKGROUND: Focus groups and workshops can be used to gain insights into the persistence of and potential solutions for environmental health priorities in underserved areas. The objective of this study was to characterize focus group and workshop outcomes of a community-academic partnership focused on addressing environmental health priorities in an urban and a rural location in Alabama between 2012 and 2019. METHODS: Six focus groups were conducted in 2016 with 60 participants from the City of Birmingham (urban) and 51 participants from Wilcox County (rural), Alabama to discuss solutions for identified environmental health priorities based on previous focus group results in 2012. Recorded focus groups were transcribed and analyzed using the grounded theory approach. Four follow-up workshops that included written survey instruments were conducted to further explore identified priorities and determine whether the priorities change over time in the same urban (68 participants) and rural (72 participants) locations in 2018 and 2019. RESULTS: Consistent with focus groups in 2012, all six focus groups in 2016 in Birmingham identified abandoned houses as the primary environmental priority. Four groups listed attending city council meetings, contacting government agencies and reporting issues as individual-level solutions. Identified city-level solutions included city-led confiscation, tearing down and transferring of abandoned property ownership. In Wilcox County, all six groups agreed the top priority was drinking water quality, consistent with results in 2012. While the priority was different in Birmingham versus Wilcox County, the top identified reason for problem persistence was similar, namely unresponsive authorities. Additionally, individual-level solutions identified by Wilcox County focus groups were similar to Birmingham, including contacting and pressuring agencies and developing petitions and protesting to raise awareness, while local policy-level solutions identified in Wilcox County included government-led provision of grants to improve septic systems, and transparency in allocation of funds. Workshops in 2018 and 2019 further emphasized water quality as the top priority in Wilcox County, while participants in Birmingham transitioned from abandoned houses as a top priority in 2018 to drinking water quality as a new priority in 2019. CONCLUSIONS: Applying a community-engaged approach in both urban and rural locations provided better understanding of the unique opportunities and challenges for identifying potential interventions for environmental health priorities in both locations. Results can help inform future efforts to address locally defined environmental health issues and solutions.

Heat-Health Behavior Change During Summer 2020 in African American Alabama Residents.

To investigate how heat-health behaviors changed in summer 2020 compared with previous summers, our community-academic partnership conducted telephone surveys to collect data on cooling behaviors, safety concerns, and preferences for cooling alternatives for 101 participants living in Alabama. Participants indicating they would visit cooling centers declined from 23% in previous summers to 10% in summer 2020. The use of cooling centers and other public spaces may be less effective in reducing heat-related illness because of safety concerns amid the COVID-19 pandemic and police brutality.

Peer coach delivered storytelling program improved diabetes medication adherence: A cluster randomized trial.

BACKGROUND: Because medication adherence is linked to better diabetes outcomes, numerous interventions have aimed to improve adherence. However, suboptimal adherence persists and necessitate continued research into intervention strategies. This study evaluated the effectiveness of an intervention that combined storytelling and peer support to improve medication adherence and health outcomes in adults with diabetes. METHODS: Living Well with Diabetes was a cluster randomized controlled trial. Intervention participants received a six-month, 11-session peer-delivered behavioral diabetes self-care program over the phone. Control participants received a self-paced general health program. Outcomes were changes in medication adherence and physiologic measures (hemoglobin A1c, systolic blood pressure, low-density lipoprotein cholesterol, body mass index). RESULTS: Of the 403 participants with follow-up data, mean age was 57 (±SD 11), 78% were female, 91% were African American, 56.4% had high school education or less, and 70% had an annual income of < $20,000. At follow-up, compared to controls, intervention participants had greater improvement in medication adherence (ß = -0.25 [95% CI -0.35, -0.15]). Physiologic measures did not change significantly in either group. Intervention participants had significant improvements in beliefs about the necessity of medications (ß = 0.87 [95% CI 0.27, 1.47]) concerns about the negative effects of medication (ß = -0.91 [95% CI -1.35, -0.47]), and beliefs that medications are harmful (ß = -0.50 [95% CI -0.89, -0.10]). In addition, medication use self-efficacy significantly improved in intervention participants (ß = 1.0 [95% CI 0.23, 1.76]). 473 individuals were enrolled in the study and randomized. DISCUSSION: Living Well intervention resulted in improved medication adherence, medication beliefs, and medication use self-efficacy but not improved risk factor levels.

Development of a Community Health Worker-Delivered Cognitive Behavioral Training Intervention for Individuals With Diabetes and Chronic Pain.

Cognitive behavioral therapy (CBT) programs have the potential to improve quality of life in individuals with chronic pain and diabetes. Rural communities often lack the infrastructure necessary to implement such programs. CBT traditionally requires trained therapists, who are rarely available in these areas. An alternative may be programs delivered by community health workers (CHWs). We present an iterative developmental approach that combined program adaptation, pretesting, and CHW training processes for a CBT-based diabetes self-care program for individuals living with diabetes and chronic pain. Collaborative intervention refinement, combined with CHW training, is a promising methodology for community-engaged research in remote, underresourced communities.

Implementation of HPV vaccination guidelines in a diverse population in Los Angeles: Results from an environmental scan of local HPV resources and needs.

Research shows that vaccination against human papillomavirus (HPV) infection is one of the most effective methods for reducing risk for cervical cancer; it also protects against other HPV-related cancers. Controversies exist regarding HPV vaccination in several communities; which may in part explain why although rates of HPV vaccination are increasing nationwide, Los Angeles County (LAC) data show that many adolescents are still not vaccinated. These adolescents remain at high-risk for infection. Using community-based participatory principles, we conducted an environmental scan that included a literature review, the development of a community advisory board, community feedback from HPV community meetings, and interviews with stakeholders to understand attitudes toward HPV vaccination and their impact in follow through with HPV vaccines. Twenty-eight key stakeholders participated in our coalition comprised of community organizations and clinics with strong ties to the local community. This is the only coalition dedicated exclusively to improving HPV vaccine uptake in LAC. Of these, twenty-one participated in an environmental scan via qualitative interviews about HPV vaccination programs, service delivery priorities, and proposed steps to increase HPV vaccination uptake in LAC. The environmental scan revealed targets for future efforts, barriers to HPV uptake, and next steps for improving local HPV vaccination uptake rates. The environmental scan also identified local HPV vaccination interventions and resources. Although LAC has developed important efforts for vaccination, some interventions are no longer being implemented due to lack of funds; others have not been evaluated with sufficient outcome data. The risk for cervical and other HPV-related cancers could be greatly reduced in LAC if a multilevel, multicultural, and multilingual approach is taken to better understand rates of HPV vaccination uptake, particularly among racial/ethnic minorities and LGBTQ youth. Our environmental scan provides guidance on attitudes toward vaccination, and how best to address the needs of LAC families and providers.

Peer Coaches to Improve Diabetes Outcomes in Rural Alabama: A Cluster Randomized Trial.

PURPOSE: It is unclear whether peer coaching is effective in minority populations living with diabetes in hard-to-reach, under-resourced areas such as the rural South. We examined the effect of an innovative peer-coaching intervention plus brief education vs brief education alone on diabetes outcomes. METHODS: This was a community-engaged, cluster-randomized, controlled trial with primary care practices and their surrounding communities serving as clusters. The trial enrolled 424 participants, with 360 completing baseline and follow-up data collection (84.9% retention). The primary outcomes were change in glycated hemoglobin (HbA1c), systolic blood pressure (BP), low density lipoprotein cholesterol (LDL-C), body mass index (BMI), and quality of life, with diabetes distress and patient activation as secondary outcomes. Peer coaches were trained for 2 days in community settings; the training emphasized motivational interviewing skills, diabetes basics, and goal setting. All participants received a 1-hour diabetes education class and a personalized diabetes report card at baseline. Intervention arm participants were also paired with peer coaches; the protocol called for telephone interactions weekly for the first 8 weeks, then monthly for a total of 10 months. RESULTS: Due to real-world constraints, follow-up was protracted, and intervention effects varied over time. The analysis that included the 68% of participants followed up by 15 months showed only a significant increase in patient activation in the intervention group. The analysis that included all participants who eventually completed follow-up revealed that intervention arm participants had significant differences in changes in systolic BP (P = .047), BMI (P = .02), quality of life (P = .003), diabetes distress (P = .004), and patient activation (P = .03), but not in HbA1c (P = .14) or LDL-C (P = .97). CONCLUSION: Telephone-delivered peer coaching holds promise to improve health for individuals with diabetes living in under-resourced areas.
