Mentored implementation to initiate a diabetes program in an underserved community: a pilot study

A community health worker led diabetes self-management education program: Reducing patient and system burden

AIMS

Conduct a secondary analysis of the TIME (Telehealth-supported, Integrated Community Health Workers (CHWs), Medication access, diabetes Education) made simple trial (SIMPLE) to evaluate healthcare utilization and explore variables that may have influenced HbA1c.

METHODS

Participants (N = 134 [67/group]) were low-income, uninsured Hispanics with or at risk for type 2 diabetes mellitus. We included in-person and telehealth clinician visits, other visits, missed visits, orders placed, and guideline-adherence (e.g., vaccinations, quarterly HbA1c for uncontrolled diabetes). Using multivariable models, we explored for associations between HbA1c changes and these measures.

RESULTS

The control arm had higher missed visits rates (intervention: 45 %; control: 56 %; p = 0.007) and missed telehealth appointments (intervention: 10 %; control: 27.4 %; p = 0.04). The intervention group received more COVID vaccinations than the control (p = 0.005). Other health measures were non-significant between groups. Intervention individuals' HbA1c improved with more missed visits (-0.60 %; p < 0.01) and worsened with improved guideline-adherent HbA1c measurements (HbA1c: 1.2 %; p = 0.057). The control group had non-significant HbA1c associations.

CONCLUSIONS

Findings suggest that the SIMPLE trial's improved HbA1c levels stemmed from a CHW-driven intervention and not additional healthcare contact. Exploratory outcomes resulted in seemingly counterintuitive HbA1c associations with missed visits and guideline-adherent measurements; these may suggest that an intervention that enhances communication provides support to reduce the amount of follow-up needed by participants without sacrificing clinical improvements.

Use of Community Health Workers Among U.S. Male Latino Population: A Scoping Review

Community Health Workers (CHWs) are an effective strategy to address the health needs of specified communities. The purpose of this scoping review was to explore the use of CHWs to address the health needs of the Latino male population. This project used specific search terms to identify relevant articles from PubMed, PsycINFO, and Google Scholar. Eligible articles included studies, conducted in the U.S. and in English from 2010 to 2022, that assessed the use of CHWs among a predominantly male (≥ 50%) Latino population. Twenty articles consisting of 13 interventions were identified for review and were further categorized into male-only participant samples (n = 10) and mixed-gender but predominantly-male participant samples (n = 10) for synthesis. Male-only participant samples focused on occupational health and participant's social support and networks. Predominantly-male, mixed-gender participant sample interventions were disease-centered and emphasized the longitudinal support of CHWs as well as social networks. Of the 13 interventions reviewed, almost all (n = 10) utilized existing social networks for engagement and nearly half (n = 6) employed community-based participatory research (CBPR) principles. Findings suggest that recruiting CHWs from within existing social networks and using CBPR are important factors for successful health promotion among male Latinos.

Systematic Review Examining the Behavior Change Techniques in Medication Adherence Intervention Studies Among People With Type 2 Diabetes

BACKGROUND

Although previous systematic reviews have studied medication adherence interventions among people with Type 2 diabetes (PwT2D), no intervention has been found to improve medication adherence consistently. Furthermore, inconsistent and poor reporting of intervention description has made understanding, replication, and evaluation of intervention challenging.

PURPOSE

We aimed to identify the behavior change techniques (BCTs) and characteristics of successful medication adherence interventions among PwT2D.

METHODS

A systematic search was conducted on Medline, Embase, CINAHL, PsycINFO, Cochrane Central Register of Controlled Trials, Web of Science, and Scopus. Studies were included if they were randomized controlled trials with BCT-codable interventions designed to influence adherence to anti-diabetic medication for PwT2D aged 18 years old and above and have medication adherence measure as an outcome.

RESULTS

Fifty-five studies were included. Successful interventions tend to target medication adherence only, involve pharmacists as the interventionist, contain "Credible source" (BCT 9.1), "Instruction on how to perform the behaviour" (BCT 4.1), "Social support (practical)" (BCT 3.2), "Action planning" (BCT 1.4), and/ or "Information about health consequences" (BCT 5.1). Very few interventions described its context, used theory, examined adherence outcomes during the follow-up period after an intervention has ended, or were tailored to address specific barriers of medication adherence.

CONCLUSION

We identified specific BCTs and characteristics that are commonly reported in successful medication adherence interventions, which can facilitate the development of future interventions. Our review highlighted the need to consider and clearly describe different dimensions of context, theory, fidelity, and tailoring in an intervention.

Effectiveness of shared medical appointments delivered in primary care for improving health outcomes in patients with long-term conditions: a systematic review of randomised controlled trials

OBJECTIVES

To examine the effectiveness of shared medical appointments (SMAs) compared with one-to-one appointments in primary care for improving health outcomes and reducing demand on healthcare services by people with one or more long-term conditions (LTCs).

DESIGN

A systematic review of the published literature.

DATA SOURCES

Six databases, including MEDLINE and Web of Science, were searched 2013-2023. Relevant pre-2013 trials identified by forward and backward citation searches of the included trials were included.

ELIGIBILITY CRITERIA

Randomised controlled trials of SMAs delivered in a primary care setting involving adults over 18 years with one or more LTCs. Studies were excluded if the SMA did not include one-to-one patient-clinician time. All countries were eligible for inclusion.

DATA EXTRACTION AND SYNTHESIS

Data were extracted and outcomes narratively synthesised, meta-analysis was undertaken where possible.

RESULTS

Twenty-nine unique trials were included. SMA models varied in terms of components, mode of delivery and target population. Most trials recruited patients with a single LTC, most commonly diabetes (n=16). There was substantial heterogeneity in outcome measures. Meta-analysis showed that participants in SMA groups had lower diastolic blood pressure than those in usual care (d=-0.086, 95% CI=-0.16 to -0.02, n=10) (p=0.014). No statistically significant differences were found across other outcomes. Compared with usual care, SMAs had no significant effect on healthcare service use. For example, no difference between SMAs and usual care was found for admissions to emergency departments at follow-up (d=-0.094, 95% CI=-0.27 to 0.08, n=6, p=0.289).

CONCLUSIONS

There was a little difference in the effectiveness of SMAs compared with usual care in terms of health outcomes or healthcare service use in the short-term (range 12 weeks to 24 months). To strengthen the evidence base, future studies should include a wider array of LTCs, standardised outcome measures and more details on SMA components to help inform economic evaluation.

Preparing Community Health Workers to Empower Latino(a)s With Diabetes: A Real-World Implementation Study

PURPOSE

The purpose of the study was to evaluate the delivery of diabetes self-management education (DSME) to Latino(a) adults by community health workers (CHWs).

METHODS

Investigators developed an evidence-based, bilingual (Spanish/English) diabetes education curriculum and trained 10 CHWs on its content. CHWs then implemented the curriculum in 6-month diabetes group visit programs for low-income Latino(a)s with type 2 diabetes in nonacademic 501(c)3 community clinics. Investigators evaluated efficacy of the training through successful implementation, measured by participant group visit acceptance and attendance.

RESULTS

Participants (n = 70) reported high levels of program satisfaction (3.8/4.0), improvement in quality of life (9.7/10), meeting of individual needs (3.8/4.0), and acceptability (9.7/10.0). Content analyses revealed that 87.1% of participants would not change the program or wanted to extend it. Participant attendance was 81.6%.

CONCLUSIONS

Investigators demonstrated the ability to develop a training that nonmedical personnel (CHWs) successfully implemented in a real-world study. This study provides a curricular framework for CHW-led education that may serve as a template to extend to other diseases and populations.

Implementation and Evaluation of a mHealth-Based Community Health Worker Feedback Loop for Hispanics with and at Risk for Diabetes

BACKGROUND

Gaps in accessibility and communication hinder diabetes care in poor communities. Combining mobile health (mHealth) and community health workers (CHWs) into models to bridge these gaps has great potential but needs evaluation.

OBJECTIVE

To evaluate a mHealth-based, Participant-CHW-Clinician feedback loop in a real-world setting.

DESIGN

Quasi-experimental feasibility study with intervention and usual care (UC) groups.

PARTICIPANTS

A total of 134 participants (n = 67/group) who were all low-income, uninsured Hispanics with or at-risk for type 2 diabetes.

INTERVENTION

A 15-month study with a weekly to semimonthly mHealth Participant-CHW-Clinician feedback loop to identify participant issues and provide participants monthly diabetes education via YouTube.

MAIN MEASURES

We used pre-defined feasibility measures to evaluate our intervention: (a) implementation, the execution of feedback loops to identify and resolve participant issues, and (b) efficacy, intended effects of the program on clinical outcomes (baseline to 15-month HbA1c, systolic blood pressure (SBP), diastolic blood pressure (DBP), and weight changes) for each group and their subgroups (at-risk; with diabetes, including uncontrolled (HbA1c ≥ 7%)).

KEY RESULTS

CHWs identified 433 participant issues (mean = 6.5 ± 5.3) and resolved 91.9% of these. Most issues were related to supplies, 26.3% (n = 114); physical health, 23.1% (n = 100); and medication access, 20.8% (n = 90). Intervention participants significantly improved HbA1c (- 0.51%, p = 0.03); UC did not (- 0.10%, p = 0.76). UC DBP worsened (1.91 mmHg, p < 0.01). Subgroup analyses revealed HbA1c improvements for uncontrolled diabetes (intervention: - 1.59%, p < 0.01; controlled: - 0.72, p = 0.03). Several variables for UC at-risk participants worsened: HbA1c (0.25%, p < 0.01), SBP (4.05 mmHg, p < 0.01), DBP (3.21 mmHg, p = 0.01). There were no other significant changes for either group.

CONCLUSIONS

A novel mHealth-based, Participant-CHW-Clinician feedback loop was associated with improved HbA1c levels and identification and resolution of participant issues. UC individuals had several areas of clinical deterioration, particularly those at-risk for diabetes, which is concerning for progression to diabetes and disease-related complications.

Interventions to tackle health inequalities in cardiovascular risks for socioeconomically disadvantaged populations: a rapid review

INTRODUCTION

Cardiovascular disease (CVD) has shown significant health inequalities for people with low socioeconomic status associated with more risk factors. This review was to synthesize interventions that targeted CVD risks and outcomes among socioeconomically disadvantaged populations and to understand the impact associated with these interventions.

SOURCES OF DATA

Cochrane CENTRAL, MEDLINE, Embase, PsycINFO and CINAHL were searched for records published in the last decade using a systematic search strategy, complemented by screening the reference lists and citation indexes. Nineteen studies were included and a narrative synthesis with the effect direction plot was undertaken in which studies, interventions, participants and outcomes were examined according to the intervention type focusing on behaviours, lifestyle, education, medication and monitoring.

AREAS OF AGREEMENT

No universal definition of disadvantaged socioeconomic status was used with common factors relating to racial/ethnic minorities, low income and low or no health insurance. Mixed effects of interventions were reported on clinical outcomes including weight, body mass index, blood pressure, glycated haemoglobin and cholesterol.

AREAS OF CONTROVERSY

Inconsistent effect was reported due to a large variety of settings, participants and intervention components although they are considered necessary to address the complex health needs of socioeconomically disadvantaged populations.

GROWING POINTS

There is inadequate evidence to determine whether any of the intervention types are effective in optimising lipids management for socioeconomically disadvantaged populations.

AREAS TIMELY FOR DEVELOPING RESEARCH

Research is needed with mixed evidence using real world evaluation and lived experience combined with health economic evaluation, on both mental and physical health outcomes.

Determining call-to-entry rate and recruitment barriers in clinical studies for community clinics serving low-income populations: a cohort study

BACKGROUND

Recruitment for clinical studies is challenging. To overcome barriers, investigators have previously established call-to-entry rates to assist in planning. However, rates specific to low-income minority populations are needed to account for additional barriers to enrolment these individuals face.

OBJECTIVE

To obtain a call-to-entry rate in a low-income uninsured Hispanic population with chronic disease.

METHODS

We used data from four of our randomised clinical studies to determine the call-to-entry rate for individuals (n=1075) with or at risk for type 2 diabetes: participants needed/potential participants contacted=recruitment rate (yield). Research staff contacted potential participants to enrol in a study that evaluated 6 month diabetes programmes at community clinics from 2015 to 2020. We recorded call-to-entry rates, reasons for declining the study, show rates, and attrition.

RESULTS

The call-to-entry rate was 14.5%. Forty per cent of potential participants could not be contacted, and 30.6%, 19.1%, and 5.4% responded yes, no, and maybe, respectively. No show percentages were 54% for yes and 91.4% for maybe responders. The majority (61.6%) declined due to inability to attend; reasons to decline included work (43%), eligibility (18%), transportation (10%), out of town (9%), did not think they needed the programme (7%) and other/unknown (14%). Being a physician predicted inability to reach participants (adjusted OR 2.91, 95% CI 1.73 to 4.90). Attrition was 6.8%.

CONCLUSIONS

We described a call-to-entry rate and detailed recruitment data, including reasons to decline the study. This valuable information can assist investigators in study planning and overcoming enrolment barriers in low-income populations. Telehealth-based or strategies that limit transportation needs may increase participant involvement.

Electronic health strategies to improve medication adherence in patients with cardiometabolic disease: current status and future directions

PURPOSE OF REVIEW

Enabled by widespread technological advancements, electronic health (eHealth) strategies have expanded rapidly over the last decade, presenting opportunities to support self-management including medication adherence for cardiometabolic disease control. eHealth can minimize access barriers to medications, enable timely assessment and shared decision-making, and provide medication reminders and health data feedback. This review summarizes current evidence for effectiveness of eHealth strategies for improving medication adherence in patients with hypertension, type 2 diabetes, and/or hyperlipidemia, and identifies priorities for future research.

RECENT FINDINGS

Current research supports the effectiveness of eHealth strategies to improve medication adherence and clinical outcomes for cardiometabolic disease. Although patient acceptability of eHealth strategies is generally high, engagement may decline over time. In addition, differences in effectiveness across intervention characteristics and sociodemographic groups are understudied, limiting generalizability and tailoring of interventions to local health system resources, culture, and patient needs or preferences.

SUMMARY

eHealth is a promising tool for addressing low medication adherence. Further work incorporating rigorous evaluation, assessment of patient engagement over time and effectiveness of intervention characteristics and components, and a health equity lens addressing eHealth use in vulnerable groups will increase understanding of the full potential of eHealth for improving medication adherence in diverse patients with cardiometabolic disease.

Feasibility and Acceptability of the HOME Model to Promote Self-Management Among Ethnic Minority Elderly with Type 2 Diabetes Mellitus in Rural Thailand: A Pilot Study

Introduction:

Ethnic minority elderly (EME) people are recognized as a vulnerable group who have higher prevalence of type 2 diabetes mellitus (T2DM) than the majority of the population. The aim of this study was to explore the feasibility, acceptability, and effect of the HOME model (Home intervention; Online monitoring; Multidisciplinary approach; and Equity and education) specifically for enhancing self-management activities, glycemic control, and satisfaction of EME with T2DM in rural areas in Thailand.

Methods:

In this quasi-experimental study, a single group used a pre-test and post-test, which were conducted as a pilot study to examine the effect of the HOME model.

Results:

Overall, 23 dyads of EME with T2DM and their family caregivers completed the 12-week intervention. They reported that the HOME model was helpful and motivating, and they reported satisfaction with the service provided. EME with T2DM showed significant reduction of blood glucose level, and significant improvement in self-management activities, happiness, and satisfaction compared with baseline. Family caregivers had also significant improvements in happiness and reported satisfaction with the HOME model.

Conclusion:

The primary evidence suggested that the HOME model was acceptable and feasible for EME with T2DM and their families in rural Thailand.
