Adaptation of an Evidence-Based Diabetes Management Intervention for Delivery in Community Settings: Findings From a Pilot Randomized Effectiveness Trial.

Objective: To adapt an evidence-based intervention targeting diabetes management in adolescents with poorly controlled type 1 diabetes for use in a community setting by community health workers (CHWs) and to conduct pilot testing of the new intervention, REACH for Control (RFC). The study was conducted as a collaboration between university researchers and a federally qualified health center. Methods In a pilot effectiveness trial, feasibility and acceptability of RFC were evaluated based on participant enrollment, treatment dose, and consumer satisfaction. RFC effects on adolescent adherence, health outcomes, and quality of life were also assessed. The trial used a parallel group design. Families were randomized to 6 months of RFC plus standard medical care (n = 26) or standard care (SC) only (n = 24). Data were collected at baseline and 7-month posttest. A mixed-methods approach was used to analyze data. Results: Qualitative analyses suggested that caregivers viewed RFC and delivery of a home-based intervention by CHWs positively. Furthermore, adolescents who received RFC had statistically significant (p = .05) and clinically meaningful improvements in hemoglobin A1c (HbA1c) (0.7%) and reported significant improvements in quality of life from baseline to follow-up (p = .001). No significant changes were found for adolescents in standard medical care. However, while dose of primary intervention session delivered was acceptable, dose of follow-up sessions used for skills practice was low. Conclusions: Results provide preliminary support for RFC's acceptability and effectiveness to improve health status and quality of life when used in community settings serving high-risk, low-income families. Additional testing in a full-scale effectiveness trial appears warranted.

Comparison of community health worker-led diabetes medication decision-making support for low-income Latino and African American adults with diabetes using e-health tools versus print materials: a randomized, controlled trial.

BACKGROUND: Health care centers serving low-income communities have scarce resources to support medication decision making among patients with poorly controlled diabetes. OBJECTIVE: To compare outcomes between community health worker use of a tailored, interactive, Web-based, tablet computer-delivered tool (iDecide) and use of print educational materials. DESIGN: Randomized, 2-group trial conducted from 2011 to 2013 (ClinicalTrials.gov: NCT01427660). SETTING: Community health center in Detroit, Michigan, serving a Latino and African American low-income population. PARTICIPANTS: 188 adults with a hemoglobin A1c value greater than 7.5% (55%) or those who reported questions, concerns, or difficulty taking diabetes medications. INTERVENTION: Participants were randomly assigned to receive a 1- to 2-hour session with a community health worker who used iDecide or printed educational materials and 2 follow-up calls. MEASUREMENTS: Primary outcomes were changes in knowledge about antihyperglycemic medications, patient-reported medication decisional conflict, and satisfaction with antihyperglycemic medication information. Also examined were changes in diabetes distress, self-efficacy, medication adherence, and hemoglobin A1c values. RESULTS: Ninety-four percent of participants completed 3-month follow-up. Both groups improved across most measures. iDecide participants reported greater improvements in satisfaction with medication information (helpfulness, P = 0.007; clarity, P = 0.03) and in diabetes distress compared with the print materials group (P < 0.001). The other outcomes did not differ between the groups. LIMITATIONS: The study was conducted at 1 health center during a short period. The community health workers were experienced in behavioral counseling, thereby possibly mitigating the need for additional support tools. CONCLUSION: Most outcomes were similarly improved among participants receiving both types of decision-making support for diabetes medication. Longer-term evaluations are necessary to determine whether the greater improvements in satisfaction with medication information and diabetes distress achieved in the iDecide group at 3 months translate into better longer-term diabetes outcomes.

Changes in Self-management During the COVID-19 Pandemic Among Adults with Type 2 Diabetes at a Federally Qualified Health Center.

The COVID-19 pandemic affected how adults with diabetes perform self-management, and impacts may be greater among vulnerable populations. We assessed the impact of the pandemic on diabetes self-management among adults with type 2 diabetes at a Federally Qualified Health Center. Participants were surveyed by phone in Spanish and English from July to October of 2020. Most respondents (74%) were Latino and preferred to speak Spanish, with mean age of 54 years and mean HbA1c of 9.2%. Fifty-three percent reported less physical activity during the pandemic. While 43% had more difficulty obtaining healthy food, 38% reported eating more healthfully. Sixty-one percent had increased difficulty accessing medical care. Many felt more socially isolated (49%) and stressed (51%). Changes in diabetes self-management were both positive and negative for majority Latino patients in this low-resource community, which may require tailored approaches to mitigate negative impacts of the pandemic on physical and mental health.

Comparing the effectiveness of Family Support for Health Action (FAM-ACT) with traditional community health worker-led interventions to improve adult diabetes management and outcomes: study protocol for a randomized controlled trial.

BACKGROUND: Diabetes self-management education and support (DSMES) programs have struggled to deliver sustainable, effective support for adults with diabetes (AWDs) to improve self-management behaviors, achieve glycemic goals, and reduce risk for complications. One largely untapped resource for this support is AWDs' social networks. Fifty to 75% of AWDs have an unpaid family member or friend ("support person") who provides ongoing help with diabetes management. However, DSMES interventions to date lack structured and effective approaches to directly engage support persons in AWDs' diabetes management. METHODS: This parallel arm randomized trial is designed to determine the effectiveness of Family Support for Health Action (FAM-ACT), a novel community health worker (CHW)-delivered program focused on educating and supporting patients with type 2 diabetes (T2D) and their support persons (SPs), relative to an established, CHW-delivered, individual patient-focused DSMES and care management (I-DSMES) intervention. Both interventions were developed using a community-based participatory research (CBPR) approach. The study will be conducted in partnership with an urban Federally Qualified Health Center (FQHC) serving a low-income, Latino/a community, with target enrollment of 268 dyads consisting of an FQHC patient with T2D with high HbA1c and an SP. Patient-SP dyads will be randomized to receive FAM-ACT or I-DSMES over 6 months. The primary outcome is change in patient HbA1c from baseline to 6 months. Secondary patient outcomes include 12-month change in HbA1c, changes in patient blood pressure, diabetes self-management behaviors, diabetes distress, patient activation, diabetes self-efficacy, and perceptions of and satisfaction with SP support for diabetes. Secondary SP outcomes include self-efficacy for helping the patient with diabetes management and SP distress about the patient's diabetes. We also will assess the effect of the COVID-19 pandemic on patient's ability to manage diabetes. DISCUSSION: This study will inform scalable, evidence-based approaches that leverage family support to help AWDs improve and sustain self-management strategies that underpin optimal management of multiple diabetes complication risk factors. The protocol is designed for and evaluated with a low-income and predominantly Latino/a community, which may increase applicability to other similar communities. The COVID-19 pandemic presented several challenges to study protocol and intervention delivery; modifications made to address these challenges are described.

Using path analysis to model the process of change in HbA1c among African Americans and Latinos in a community health worker diabetes intervention.

OBJECTIVE: To examine which components of a culturally tailored community health worker (CHW) intervention improved glycemic control and intermediate outcomes among Latina/o and African American participants with diabetes. METHODS: The sample included 326 African American and Latina/o adults with type 2 diabetes in Detroit, MI. CHWs provided interactive group diabetes self-management classes and home visits, and accompanied clients to a clinic visit during the 6-month intervention period. We used path analysis to model the processes by which each intervention component affected change in diabetes self-efficacy, diabetes-related distress, knowledge of diabetes management, and HbA1c. RESULTS: The group-based healthy lifestyle component was significantly associated with improved knowledge. The group-based self-management section was significantly associated with reduced diabetes-related distress. Intervention class attendance was positively associated with self-efficacy. Diabetes self-management mediated the reductions in HbA1c associated with reductions in diabetes distress. CONCLUSIONS: Path analysis allowed each potential pathway of change in the intervention to be simultaneously analyzed to identify which aspects of the CHW intervention contributed to changes in diabetes-related behaviors and outcomes among African Americans and Latinas/os. PRACTICE IMPLICATIONS: Findings reinforce the importance of interactive group sessions in efforts to improve diabetes management and outcomes among Latina/o and African American adults with diabetes.

Effectiveness of a community health worker intervention among African American and Latino adults with type 2 diabetes: a randomized controlled trial.

OBJECTIVES: We tested the effectiveness of a culturally tailored, behavioral theory-based community health worker intervention for improving glycemic control. METHODS: We used a randomized, 6-month delayed control group design among 164 African American and Latino adult participants recruited from 2 health systems in Detroit, Michigan. Our study was guided by the principles of community-based participatory research. Hemoglobin A1c (HbA1c) level was the primary outcome measure. Using an empowerment-based approach, community health workers provided participants with diabetes self-management education and regular home visits, and accompanied them to a clinic visit during the 6-month intervention period. RESULTS: Participants in the intervention group had a mean HbA1c value of 8.6% at baseline, which improved to a value of 7.8% at 6 months, for an adjusted change of -0.8 percentage points (P < .01). There was no change in mean HbA1c among the control group (8.5%). Intervention participants also had significantly greater improvements in self-reported diabetes understanding compared with the control group. CONCLUSIONS: This study contributes to the growing evidence for the effectiveness of community health workers and their role in multidisciplinary teams engaged in culturally appropriate health care delivery.

A Community Participatory Approach to Identify Common Evaluation Indicators for Community Health Worker Practice.

BACKGROUND: Substantial evidence supports community health workers' (CHWs) contributions to improving health and reducing inequities. Common evaluation indicators can strengthen the evidence base and support the profession. OBJECTIVES: We describe the development of a 6-year community-academic partnership to identify common CHW process and outcome indicators. METHODS: Methods include interviews, focus groups and a survey conducted in Michigan, a Summit in Oregon, consultations at national conferences, and regular conference calls. RESULTS: Using popular education as a primary strategy, we have honed our original goal, identified a set of 20 recommended constructs, developed a national constituency with international connections, and obtained dedicated funding. CONCLUSIONS: Participatory identification, development, and uptake of a set of common indicators (CI) for CHW practice will allow data to be aggregated at multiple levels, potentially leading to more sustainable financing of CHW programs. Given that measurement drives practice, a set of common CHW indicators can help to preserve the flexibility and integrity of the CHW role.

Cost-Effectiveness of a Diabetes Self-Management Education and Support Intervention Led by Community Health Workers and Peer Leaders: Projections From the Racial and Ethnic Approaches to Community Health Detroit Trial.

OBJECTIVE: To simulate the long-term cost-effectiveness of a peer leader (PL)-led diabetes self-management support (DSMS) program following a structured community health worker (CHW)-led diabetes self-management education (DSME) program in reducing risks of complications in people with type 2 diabetes (T2D). RESEARCH DESIGN AND METHODS: The trial randomized 222 Latino adults with T2D to 1) enhanced usual care (EUC); 2) a CHW-led, 6-month DSME program and 6 months of CHW-delivered monthly telephone outreach (CHW only); or 3) a CHW-led, 6-month DSME program and 12 months of PL-delivered weekly group sessions with telephone outreach to those unable to attend (CHW + PL). Empirical data from the trial and the validated Michigan Model for Diabetes were used to estimate cost and health outcomes over a 20-year time horizon from a health care sector perspective, discounting both costs and benefits at 3% annually. The primary outcome measure was the incremental cost-effectiveness ratio (ICER). RESULTS: Over 20 years, the CHW + PL intervention had an ICER of $28,800 and $5,900 per quality-adjusted life-year (QALY) gained compared with the EUC and CHW-only interventions, respectively. The CHW-only intervention had an ICER of $430,600 per QALY gained compared with the EUC intervention. In sensitivity analyses, the results comparing the CHW + PL with EUC and CHW-only interventions were robust to changes in intervention effects and costs. CONCLUSIONS: The CHW + PL-led DSME/DSMS intervention improved health and provided good value compared with the EUC intervention. The 6-month CHW-led DSME intervention without further postintervention CHW support was not cost effective in Latino adults with T2D.

Racial/Ethnic Discrimination and Diabetes-Related Outcomes Among Latinos with Type 2 Diabetes.

Discrimination is associated with adverse health outcomes, but few studies have examined the association of discrimination with diabetes-related outcomes including mental health and glycemic control, particularly for immigrant and US-born Latinos. We analyzed survey data (n = 222) collected at baseline of a diabetes intervention. Using multiple linear regression, we examined the association of racial/ethnic discrimination with depressive symptoms, diabetes-related distress, and HbA1c, and variation in these associations by nativity and, for immigrants, length of US residence. Racial/ethnic discrimination was positively associated with depressive symptoms (b = 2.57, SE = 0.45, p < 0.01) and diabetes-related distress (b = 0.30, SE = 0.09, p < 0.01). We could not reject the null hypothesis of no cross-sectional association of racial/ethnic discrimination with HbA1c (b = - 0.27, SE = 0.18, p = 0.14). Although racial/ethnic discrimination did not directly affect HbA1c, racial/ethnic discrimination had a significant mediating effect on HbA1c through diabetes-related distress (p = 0.02). Results suggest that racial/ethnic discrimination is detrimental for health for Latinos with diabetes.

When is social support important? The association of family support and professional support with specific diabetes self-management behaviors.

BACKGROUND: Social support is associated with better diabetes self-management behavior (SMB), yet interventions to increase family and friend support (FF support) have had inconsistent effects on SMB. OBJECTIVE: To test whether FF support differentially affects specific SMBs and compare the influence of support from health professionals and psychological factors on specific SMBs to that of FF support. DESIGN: Cross-sectional survey of people with diabetes recruited for a self-management intervention PARTICIPANTS AND SETTING: One hundred sixty-four African-American and Latino adults with diabetes living in inner-city Detroit MEASUREMENTS AND MAIN RESULTS: For every unit increase in FF support for glucose monitoring, the adjusted odds ratio (AOR) of completing testing as recommended was 1.77 (95% CI 1.21-2.58). FF support was not associated with four other SMBs (taking medicines, following a meal plan, physical activity, checking feet). Support from non-physician health professionals was associated with checking feet [AOR 1.72 (1.07-2.78)] and meal plan adherence [AOR = 1.61 (1.11-2.34)]. Diabetes self-efficacy was associated with testing sugar, meal plan adherence, and checking feet. Additional analyses suggested that self-efficacy was mediating the effect of FF support on diet and checking feet, but not the FF support effect on glucose monitoring. CONCLUSIONS: The association between FF support and SMB performance was stronger for glucose monitoring than for other SMBs. Professional support and diabetes self-efficacy were each independently associated with performance of different SMBs. SMB interventions may need to differentially emphasize FF support, self-efficacy, or professional support depending on the SMB targeted for improvement.

Effectiveness of a Community Health Worker-Led Diabetes Intervention among Older and Younger Latino Participants: Results from a Randomized Controlled Trial.

Diabetes management for older Latino adults is complex, given a higher incidence of multiple coexisting medical conditions and psychosocial barriers to self-management. Community health workers (CHWs) may be effective in reducing these barriers. The REACH Detroit CHW randomized controlled intervention studies with Latino/as with diabetes found improvements in self-management behaviors and glucose control after participating in a CHW-led intervention. Using data from the REACH Detroit Partnership's cohort 3, this study used descriptive statistics and multiple linear regression analyses to evaluate whether the six-month CHW intervention had a greater effect on older Latino/as (ages 55 and older) than younger participants between baseline and post-intervention follow-up at six months. There were significant intervention effects by age group that varied by outcome. Compared to a control group that received enhanced usual care, there were statistically significant intervention effects demonstrating greater self-efficacy scores 1.27 (0.23, 2.32); p < 0.05, and reductions in HbA1c 1.02 (-1.96,-0.07); p < 0.05, among older participants in the CHW intervention, and increases in diabetes support 0.74 (0.34, 1.13); p < 0.001; and understanding of diabetes management 0.39 (0.08, 0.70); p < 0.01 among younger participants.

Outcomes at 18 Months From a Community Health Worker and Peer Leader Diabetes Self-Management Program for Latino Adults.

OBJECTIVE: This study evaluated the effectiveness of a community health worker (CHW) diabetes self-management education (DSME) program, followed by two different approaches to maintain improvements in HbA1c and other clinical and patient-centered outcomes over 18 months. RESEARCH DESIGN AND METHODS: The study randomized 222 Latino adults with type 2 diabetes and poor glycemic control from a federally qualified health center to 1) a CHW-led, 6-month DSME program or 2) enhanced usual care (EUC). After the 6-month program, participants randomized to the CHW-led DSME were further randomized to 1) 12 months of CHW-delivered monthly telephone outreach (CHW-only) or 2) 12 months of weekly group sessions delivered by peer leaders (PLs) with telephone outreach to those unable to attend (CHW+PL). The primary outcome was HbA1c. Secondary outcomes were blood pressure, lipid levels, diabetes distress, depressive symptoms, understanding of diabetes self-management, and diabetes social support. Assessments were conducted at baseline and at 6, 12, and 18 months. RESULTS: Participants in the CHW intervention at the 6-month follow-up had greater decreases in HbA1c (-0.45% [95% CI -0.87, -0.03]; P < 0.05) and in diabetes distress (-0.3 points [95% CI -0.6, -0.03]; P < 0.05) compared with EUC. CHW+PL participants maintained HbA1c improvements at 12 and 18 months, and CHW-only participants maintained improvements in diabetes distress at 12 and 18 months. CHW+PL participants also had significantly fewer depressive symptoms at 18 months compared with EUC (-2.2 points [95% CI -4.1, -0.3]; P < 0.05). Participants in CHW-led DSME had significant improvements in diabetes social support and in understanding of diabetes self-management at 6 months relative to EUC, but these intervention effects were not sustained at 18 months. CONCLUSIONS: This study demonstrates the effectiveness of a 6-month CHW intervention on key diabetes outcomes and of a volunteer PL program in sustaining key achieved gains. These are scalable models for health care centers in low-resource settings for achieving and maintaining improvements in key diabetes outcomes.

The development, implementation, and process evaluation of the REACH Detroit Partnership's Diabetes Lifestyle Intervention.

PURPOSE: The purpose of this article was to describe the development, implementation, and process evaluation findings of a culturally tailored diabetes lifestyle intervention for African Americans and Latinos. METHODS: African American and Latino adults with type 2 diabetes from 3 health care systems in Detroit, Michigan, participated in diabetes lifestyle intervention of the Racial and Ethnic Approaches to Community Health Detroit Partnership. The intervention curricula were culturally and linguistically tailored for each population. Trained community residents delivered the curricula in 5 group meetings aimed at improving dietary, physical activity, and diabetes self-care behaviors of study participants. The aims of the process evaluation were to assess participant satisfaction with the intervention, utility, and applicability of information and cultural relevance of intervention materials. Content analysis was used to analyze qualitative data. Matrices were developed along thematic lines, and common themes were determined by grouping responses by question. RESULTS: Ninety-eight percent of participants attended 1 or more intervention classes; 41% attended all 5 meetings. Attendance rates ranged from 59% to 88% for individual meetings. Participants reported that program information and activities were useful, culturally relevant, and applicable to diabetes self-management. Participants also appreciated the convenient community location for meetings and the social support received from other participants. CONCLUSIONS: A community-based, culturally tailored diabetes lifestyle intervention delivered by trained community residents was associated with high participant satisfaction and retention.

Does Racial/Ethnic Identity Influence the Effectiveness of a Community Health Worker Intervention for African American and Latino Adults With Type 2 Diabetes?

BACKGROUND: Community health worker (CHW) interventions are known to be an effective strategy to improve health behaviors and outcomes in relation to diabetes, particularly for racial/ethnic communities. Although understanding the function of identity with same race/ethnicity among clients of CHW interventions could contribute to more effective program design, few studies have explored whether levels of racial/ethnic identity among participants can influence the effectiveness of CHW interventions. AIMS: We tested the relationship between level of racial/ethnic identity and changes in hemoglobin A1c and diabetes self-efficacy among low-income African American and Latino adults with type 2 diabetes who participated in a CHW intervention. METHODS: Data came from a randomized controlled trial of the CHW intervention with a 6-month delayed control group design for 164 African American and Latino adults in Detroit, Michigan. Racial/ethnic identity was created from two items and classified into high, moderate, and low. We combined the two arms (immediate and delayed) into one because there was no significant difference in baseline characteristics, other than age and postintervention self-efficacy, and multivariable linear regression models were applied in the analysis. RESULTS: Possession of high racial/ethnic identity was associated with greater improvement both in hemoglobin A1c and diabetes self-efficacy at 6 months. Moreover, among those with high hemoglobin A1c at preintervention, higher racial/ethnic identity had a greater impact on hemoglobin A1c improvement, compared with those with lower identity. CONCLUSIONS: This study suggests the importance of considering racial/ethnic identity of the participants in designing and operating the CHW intervention for racial/ethnic minority population.

An Exploratory Study of the Impact of Gender on Health Behavior Among African American and Latino Men With Type 2 Diabetes.

This study explores gender values and beliefs among Latino and African American men with diabetes and examines how these values and beliefs may influence their health behaviors. Participants were recruited from individuals who participated in one of three Racial and Ethnic Approaches to Community Health Detroit Partnership diabetes self-management interventions. One focus group was conducted with African American men ( n = 10) and two focus groups were conducted with Latino men ( n = 12) over a 3-month period. Sessions lasted 90 minutes, were audiotaped, and analyzed using thematic content analysis techniques. Two themes emerged that characterize gender identity and its relationship to health behavior in men: (a) men's beliefs about being men (i.e., key aspects of being a man including having respect for themselves, authority figures, and peers; fulfilling the role as breadwinner; being responsible for serving as the leader of the family; and maintaining a sense of chivalry) and (b) influence of gender values and beliefs on health behavior (i.e., the need to maintain a strong image to the outside world, and the need to maintain control of themselves served as barriers to seeking out and engaging in diabetes self-management behaviors). Results suggest that gender values and beliefs may have implications for how health behaviors among men with diabetes. Future research should study the direct impact masculine identity has on health behaviors among men with diabetes.

Diabetes-specific emotional distress among African Americans and Hispanics with type 2 diabetes.

This study examines baseline levels and correlates of diabetes-related emotional distress among inner-city African Americans and Hispanics with type 2 diabetes. The Problem Areas in Diabetes (PAID) scale, which measures diabetes-related emotional distress, was administered to 180 African American and Hispanic adults participating in the REACH Detroit Partnership. We examined bivariate and multivariate associations between emotional distress and biological, psychosocial, and quality of health care variables for African Americans and Hispanics. Scores were significantly higher among Hispanics than African Americans. Demographic factors were stronger predictors of emotional distress for Hispanics than for African Americans. Daily hassles, physician support, and perceived seriousness and understanding of diabetes were significant for African Americans. Understanding the personal, family and community context of living with diabetes and conducting interventions that provide support and coping strategies for self-management have important implications for reducing health disparities among disadvantaged racial and ethnic groups.

Chronic disease - related behaviors and health among African Americans and Hispanics in the REACH Detroit 2010 communities, Michigan, and the United States.

OBJECTIVES: To compare chronic disease risk factors and their correlates for African American and Hispanic residents of REACH Detroit, Michigan, and the United States. METHOD: Behavioral Risk Factor Survey data from 2001-2003 were used for comparisons and regression models. RESULTS: Several chronic disease risk factors were more prevalent among REACH Detroit residents than their Michigan and U.S. counterparts. In REACH Detroit, greater fruit and vegetable consumption was associated with more than high school education and older age among Hispanics, and meeting exercise guidelines and older age among African Americans. Less than high school education, smoking, and male gender were associated with lower consumption among African Americans. Greater physical activity was associated with younger age, male gender, and more fruit and vegetable consumption among African Americans, and unemployment among Hispanics. CONCLUSIONS: Surveillance of health behaviors in high-risk communities contributes to planning interventions and policies for reducing racial and ethnic disparities.

Do pre-existing diabetes social support or depressive symptoms influence the effectiveness of a diabetes management intervention?

OBJECTIVE: Examine influences of diabetes-specific social support (D-SS) and depressive symptoms on glycemic control over time, among adults randomized to a diabetes self-management education and support (DSME/S) intervention or usual care. METHODS: Data were from 108 African-American and Latino participants in a 6-month intervention trial. Multivariable linear regression models assessed associations between baseline D-SS from family and friends and depressive symptoms with changes in HbA1c. We then examined whether baseline D-SS or depression moderated intervention-associated effects on HbA1c. RESULTS: Higher baseline D-SS was associated with larger improvements in HbA1c (adjusted ΔHbA1c -0.39% for each +1-point D-SS, p=0.02), independent of intervention-associated HbA1c decreases. Baseline depressive symptoms had no significant association with subsequent HbA1c change. Neither D-SS nor depression moderated intervention-associated effects on HbA1c. CONCLUSIONS AND PRACTICE IMPLICATIONS: Diabetes self-management education and support programs have potential to improve glycemic control for participants starting with varying levels of social support and depressive symptoms. Participants starting with more support for diabetes management from family and friends improved HbA1c significantly more over 6 months than those with less support, independent of additional significant DSME/S intervention-associated HbA1c improvements. Social support from family and friends may improve glycemic control in ways additive to DSME/S.

The Role of Evaluation in Developing and Sustaining Community Health Worker Coalitions: The Example of the Michigan Community Health Worker Alliance.

Community health workers (CHWs) have demonstrated effectiveness in improving health outcomes and addressing health inequities. Statewide CHW coalitions are supporting expansion of the CHW workforce and influencing health policy. Evaluations can play a key role in sustaining coalitions. This article discusses how evaluation has informed the development, processes, and initiatives of the Michigan Community Health Worker Alliance. We highlight the Michigan Community Health Worker Alliance's internal process evaluation, a statewide survey of CHW programs, and other evaluation activities to illustrate how CHW coalitions can use participatory evaluation to develop and reinforce coalition strengths and accomplish mutual goals.

Comparative effectiveness of peer leaders and community health workers in diabetes self-management support: results of a randomized controlled trial.

OBJECTIVE: To compare a peer leader (PL) versus a community health worker (CHW) telephone outreach intervention in sustaining improvements in HbA1c over 12 months after a 6-month diabetes self-management education (DSME) program. RESEARCH DESIGN AND METHODS: One hundred and sixteen Latino adults with type 2 diabetes were recruited from a federally qualified health center and randomized to (1) a 6-month DSME program followed by 12 months of weekly group sessions delivered by PLs with telephone outreach to those unable to attend or (2) a 6-month DSME program followed by 12 months of monthly telephone outreach delivered by CHWs. The primary outcome was HbA1c. Secondary outcomes were cardiovascular disease risk factors, diabetes distress, and diabetes social support. Assessments were conducted at baseline, 6, 12, and 18 months. RESULTS: After DSME, the PL group achieved a reduction in mean HbA1c (8.2-7.5% or 66-58 mmol/mol, P < 0.0001) that was maintained at 18 months (-0.6% or -6.6 mmol/mol from baseline [P = 0.009]). The CHW group also showed a reduction in HbA1c (7.8 vs. 7.3% or 62 vs. 56 mmol/mol, P = 0.0004) post-6 month DSME; however, it was attenuated at 18 months (-0.3% or -3.3 mmol/mol from baseline, within-group P = 0.234). Only the PL group maintained improvements achieved in blood pressure at 18 months. At the 18-month follow-up, both groups maintained improvements in waist circumference, diabetes support, and diabetes distress, with no significant differences between groups. CONCLUSIONS: Both low-cost maintenance programs led by either a PL or a CHW maintained improvements in key patient-reported diabetes outcomes, but the PL intervention may have additional benefit in sustaining clinical improvements beyond 12 months.
