Official title: A Feasibility Study of a Novel mHealth Clinical Decision Support Application to Enable Community Health Workers to Manage Hypertension With Remote Physician Supervision

Status Active, not recruiting

Clinical Trial Summary

This is a single group study assessing the feasibility of hypertension management by community health workers (CHWs) equipped with a mobile clinical decision support (CDS) application and working with remote physician supervision.

Clinical Trial Description

An estimated 1.13 billion people worldwide are currently living with hypertension, the leading preventable cause of death and disability. Two thirds of these patients live in low- and middle-income countries (LMIC). Treatment of hypertension has been found to be cost-effective in reducing morbidity and mortality across a broad range of settings. Despite this, less than 10% of patients with hypertension in LMIC have good control of their blood pressure. Health systems in LMIC, which are often focused on providing episodic care for acute illnesses and suffer from inadequate and poorly distributed health care infrastructure and workforce, are ill-equipped to address the rise in chronic non-communicable diseases (NCDs) such as hypertension. Governments and NGOs are increasingly turning to community health workers (CHWs) - lay people trained to carry out a variety of tasks and who often are from or have a close connection to the communities they serve - to help fill care gaps for hypertension and other NCDs in LMIC. In most cases, CHWs have played supportive (e.g. providing patient education) rather than direct care roles. While such programs have led to improved chronic disease outcomes, they still rely on clinic-based physicians, mid-level providers or nurses to directly provide medical management, and therefore do not address the essential problem of inadequate primary care infrastructure and workforce, particularly in rural areas. Overcoming this problem is key to reducing the growing burden of untreated hypertension in LMIC.

To solve this problem, the investigators are developing an innovative mobile application to assist CHWs in the treatment of hypertension in adults with remote physician supervision. This application is built on the widely-used CommCare platform and will provide clinical decision support (CDS) to CHWs based on protocols from the WHO and the International Society of Hypertension for antihypertensive medication initiation and titration, lifestyle counseling, and identification of patients requiring a higher level of care. The investigators will develop and test this approach in a rural area of Guatemala with poor primary care infrastructure and where the team has worked extensively in the past and has an ongoing collaboration with a local NGO, the San Lucas Mission, and affiliated CHWs. Through this collaboration, the investigators have developed and implemented a CHW-led rural diabetes program enabled by a CDS mobile application and have demonstrated that CHWs can safely and effectively manage diabetes using the application. The hypothesis is that the investigators will be able to adapt the model to hypertension management and are evaluating the feasibility of this approach with this pilot study. ;
