The Community Health Club (CHC) model is a community-based health promotion program that utilizes water, sanitation, and hygiene (WASH) education as the first stage of a longitudinal development process. Although the CHC model has been implemented in fourteen countries over 20 years, this is the first review of the literature describing the model’s outcomes and impact. We conducted a review of the literature that provided quantitative or qualitative evidence of CHC interventions focused on WASH in low- and middle-income countries. We identified 25 articles that met our inclusion criteria. We found six major outcomes: WASH behaviors and knowledge, social capital, collective action, health, and cost or cost-effectiveness. The most consistent evidence was associated with WASH behaviors and knowledge, with significant effects on defecation practices, hand washing behaviors, and WASH knowledge. We also found qualitative evidence of impact on social capital and collective action. CHCs catalyze favorable changes in WASH behaviors and knowledge, yielding outcomes commensurate with other WASH promotion strategies. This review provides insights into the model’s theory of change, helping identify areas for further investigation. The CHC model’s holistic focus and emphasis on individual and collective change offer promising potential to address multiple health and development determinants.

Although interventions that emphasize the role of knowledge in invoking behaviour change have recently become unpopular, the Community Health Club (CHC) model has demonstrated how group knowledge, consensus building, and peer pressure can be applied to achieve hygiene behaviour change. To date, the model has predominantly been implemented in rural settings, with limited testing in urban communities. In 2012, CHCs started in Haiti as a grassroots initiative, growing from six clubs in six Port-au-Prince communities to 66 clubs across 30 communities in 2015. This paper focuses on the 23 clubs formed between March 2012 and July 2014, when a retrospective process and outcome evaluation was conducted. Using a mixed methods study design, this evaluation used interviews with CHC facilitators and household surveys in three case neighbourhoods to assess how the CHC model was implemented and if differences exist between CHC graduates and non-members. The CHCs have successfully facilitated social bonding, while gradu...

COVID-19 challenged our healthcare systems and unsurprisingly, so did its vaccine. Chief among these were the uniquely politicized nature and logistical difficulties surrounding its deployment. Understanding provider attitudes toward the COVID-19 vaccines and their willingness/ability to deliver them is essential to developing an ideal vaccine distribution plan for Bexar County, Texas. An electronic survey was sent to providers serving adult patients across Bexar County. Membership includes representation from local hospitals, Bexar County Medical Society, and the San Antonio Metropolitan Health District's vaccination program. The survey measured provider attitudes toward the vaccines and asked logistical questions regarding patient hesitancy and clinic infrastructure. Responses were collected from 66 ZIP codes (90% of ZIP codes in the county), and 377 providers answered the survey. Respondents who were unlikely to recommend the vaccine (3%) shared concerns involving distrust of the vaccine manufacturing process. Recommendations made by physicians to support their vaccine administration efforts included broadening the reporting timeframe (n=35), providing trained support staff (n=18), and improving logistical support (n=14). Furthermore, responses showed that only 14.44% of provider facilities were able to meet originally published refrigeration requirements to store Pfizer's vaccines compared with 87.47% for Moderna's vaccines. Survey results were used to improve the efficiency of vaccination programs and address vaccine hesitancy through various avenues of information delivery. It is recommended to replicate the outcomes and applications of this study in other populations to improve the efficiency of vaccination programs and reduce vaccine hesitancy.
