preventing ischemic heart disease with mhealth (mobile health), electronic decision support and community health workers

Conditions: Cardiovascular Diseases (CVD)

Summary: this is a cluster-randomized clinical trial (crct) designed to assess the effectiveness of a multicomponent strategy linking key aspects of the cardiovascular disease (cvd) care continuum across three provinces in argentina using using five primary components: a data management system linking a digital mhealth (mobile health) screening tool used by community health workers (chws), an electronic appointment scheduler which is integrated with the clinic electronic appointment system, point of care (poct) testing for lipids, a clinical decision support system for medication initiation, and a text message (sms) reminder system to improve treatment adherence and life-style changes.

954 eligible women and men aged 40-74 with high cvd risk living in the catchment area of 18 primary care clinics (pccs) in 3 different provinces (quilmes, la rioja, and san juan) in argentina will be recruited for the study. eighteen pccs will be randomized to either the usual care (control) arm or the intervention arm (3 usual care and 3 intervention pccs in each province). participants who reside in the catchment area of intervention pccs will receive the multicomponent intervention with central data management system linking digital mhealth (mobile health) screening tool for chws, electronic appointment scheduling which is integrated with the clinic electronic appointment system, point of care testing (poct) for lipids, clinical decision support for medication initiation, and a sms reminder system for adherence to medications and life-style changes, while participants who reside in the catchment area of usual care pccs will receive usual care with paper-based guidelines used by community health workers and providers. the recruitment goals are 477 persons in the intervention arm and 477 in the usual care arm. participants will be enrolled for a 12 month study period from baseline visit, and the primary outcome is mean difference in absolute 10-year cvd risk.
