Developing a diabetes prevention education program for community health care workers in Thailand: translation of the knowledge to at-risk people

Competency-based education and training for Community Health Workers: a scoping review

BACKGROUND

Community Health Workers (CHWs) play a critical role in supporting the delivery of health services globally. Competency-based learning programs can improve the transfer of learning to practice. This scoping review aims to characterize the published literature on competency-based education as an instructional and curricular strategy in community health worker training programs. We conducted a scoping review of the literature to identify how, by who, and in what ways CHWs are trained using competency-based education; and to characterize the extent of available evidence, as well as the gaps in that evidence.

METHODS

We conducted a review of the peer-reviewed literature on CHW competency-based education and training published between January 2010 to March 2023, drawing from four databases: EMBASE, OVID Medline, Web of Science, and CINAHL. We followed the PRISMA guidelines for scoping reviews. A total of 713 articles were reviewed and 236 were included for extraction based on the inclusion and exclusion criteria. Due to methodological heterogeneity, results were analyzed and synthesized only through a descriptive approach.

RESULTS

The literature on competency-based CHW education and training is most voluminous in high income contexts, primarily the USA. Overall, the included studies described very small-scale training interventions. Study types included observational (qualitative, quantitative, mixed methods, case studies) intervention or experimental studies, systematic or scoping reviews, and literature reviews. The most common practice area included was 'promotive and preventive services', whereas 'personal safety' was the rarest. Learning programs tailored to CHWs with low-literacy, content tailored to local cultural contexts, and curricula that were co-designed with CHWs were identified in the literature as effective strategies for converting learning to practice. Information on institutional support for CHWs was not provided in most of the articles reviewed. While the focus of our review was on education and training and not broader supports for CHWs, we still found it notable that training was usually discussed in isolation from other related supportive factors, including professionalization and career progression.

CONCLUSIONS

We found considerable academic interest in utilizing competency-based education to support CHWs and improve their work, yet this exploration was largely limited to smaller, ad hoc programs, in high income settings. Learning programs should be tailored to the realities and practice requirements of CHWs. Further work should illuminate the extent to which the design and delivery of education and training activities lead to acquiring and maintaining the requisite competencies.

Scaling up structured lifestyle interventions to improve the management of cardiometabolic diseases in low-income and middle-income countries: a systematic review of strategies, methods and outcomes

Introduction

Cardiometabolic diseases (CMDs), the leading causes of death in low-income and middle-income countries (LMICs), are proven to be mitigated through structured lifestyle interventions (SLIs-dietary changes, physical activity, tobacco cessation and alcohol intake), but the challenge lies in scaling them up in LMICs. Therefore, we undertook a systematic review to identify the strategies, methods and outcomes used in scaling up SLI programmes to improve cardiometabolic outcomes in LMICs.

Methods

We searched studies implementing scale-up strategies (delivery approaches enhancing an intervention's adoption, implementation and sustainability), methods (theories, models and frameworks) and present outcomes (feasibility, fidelity, etc) following the Proctor E framework. We searched six databases to identify studies published in English with no time restriction, guided by the Setting, Perspective, Intervention, Comparison and Evaluation framework. Quality assessment was performed using the Cochrane risk-of-bias, National Institutes of Health and Joanna Briggs Institute tools. Given the heterogeneity of the outcome measures, we conducted a narrative synthesis of the extracted information.

Results

Out of the 26 studies included, 18 (69%) adapted SLI interventions to suit local contexts. Strategies such as system integration, strengthening facility services and training led to up to 100% attendance of participants. Notably, only four studies (15%) used theories, models and frameworks for the full scale-up process, which is crucial for large-scale implementation in resource-limited settings. 15 (58%) studies reported the feasibility of scale-up, whereas 7 (27%) reported no significant differences in lifestyle behaviours or CMD biomarkers.

Conclusions

Early community and local stakeholders' engagement is crucial for codeveloping strategies for the scale-up of SLIs. Conducting readiness assessments and system integration are all essential considerations for improving scale-up outcomes. Additionally, we strongly recommend using suitable frameworks to guide the scale-up of SLIs to maximise the benefit for the population.

Characteristics and Outcomes of Community Health Worker Training to Improve the Prevention and Control of Cardiometabolic Diseases in Low and Middle-Income Countries: A Systematic Review

Community health workers (CHWs) play an important role in controlling non-communicable diseases in low- and middle-income countries. The aim of this review was to describe the characteristics and outcomes of CHW training programs that focused on the prevention and control of cardiometabolic diseases in low- and middle-income countries (LMICs). Medline, CINAHL Complete, Academic Search Complete, Directory of Open Access Journal, ScienceDirect, ERIC, Gale Academic, and OneFile). Studies that described the training programs used to train CHWs for prevention and control of cardiovascular diseases and type2 diabetes mellitus in LMICs. Only studies that evaluated the outcomes of training programs in at least one of the 4 levels of Kirkpatrick's training evaluation model were included in the review. CHWs who underwent training focused on the prevention and control of cardiovascular disease and type 2 diabetes mellitus. We summarized the resulting evidence using qualitative synthesis through a narrative review. Training outcomes were assessed in relation to (1) CHW reactions to training, their degree of learning, and their behaviors following training, and (2) changes in biochemical and anthropometric indicators in target populations following the CHW program implementation. PROSPERO (CRD42020162116). Thirty-two studies were included. Methods used to train CHWs included: face-to-face lectures, interactive group activities, and blended teaching with online support. Training focused on identifying people with elevated risk of cardiometabolic diseases and their risk factors as well as supporting people to adopt healthy lifestyles. Many studies that utilized trained CHWs did not publish CHW training methods and evaluations, and therefore could not be included in this study. Training programs resulted in an increase in knowledge and skills among CHWs demonstrating that there are certain activities that can be shifted to CHWs following training.

Community-based educational interventions for prevention of type II diabetes: a global systematic review and meta-analysis

PURPOSE

Our objective was to estimate the change in community-based education interventions throughout the world that may effectuate in risk parameters of type II diabetes (T2D), including the diabetes incidence rate, fasting blood glucose, hemoglobin A1C, body mass index, waist circumference, and systolic and diastolic blood pressure.

METHODS

A comprehensive search for globally eligible studies was conducted on PubMed, Embase, ProQuest, CINAHL nursing & allied health source, Cochrane Library, Google Scholar, conference proceedings, and reference lists. Data were extracted using JBI standardized data extraction tool. The primary outcome variables were diabetes incidence rate, fasting blood sugar (FBS), hemoglobin A1c (HbAlc), body mass index (BMI), waist circumference (WC), systolic/diastolic blood pressure (s/d BP). Random-effects meta-analysis and sub-group analyses were conducted.

RESULTS

Nineteen interventional studies were included in the review, and ten studies were pooled in the meta-analysis (n = 16,106, mean age = 41.5 years). The incidence rate of T2D was reported in three trials, within which the risk of developing T2D was reduced by 54.0% in favor of community-based educational interventions, (RR = 0.54, 95% CI = 0.38-0.75; p < 0.001). In eleven (n = 11,587) and six (n = 6416) studies, the pooled mean differences were - 0.33 (95% CI: - 0.45 to - 0.20, p < 0.0001) and - 0.15 (95% CI: - 0.28 to - 0.03, p < 0.0001) for FBS and HbA1c levels, respectively. Positive significant effects were observed on reducing BMI [pooled mean difference = - 0.47 (95% CI: - 0.66 to - 0.28), I² = 95.7%, p < 0.0001] and WC [pooled mean difference = - 0.66 (95% CI: - 0.89 to - 0.43), I² = 97.3%, p < 0.0001]. The use of theoretical frameworks was found to provide a 48.0% change in fasting blood sugar.

CONCLUSIONS

Based on a comprehensive data collection of about 16,106 participants and reasonable analyses, we conclude that educational interventions may reduce diabetes incidence by 54.0%, particularly through reductions in fasting blood glucose, body mass index, and waist circumference. The diabetes risk parameters may favorably improve irrespective of the duration of intervention, at as low as 6 months. The application of theoretical frameworks while designing educational interventions is also encouraged.
