Why the study?
Task sharing for hypertension management could be useful in understaffed, resource-poor health systems, but its effectiveness in low-income and middle-income countries needed assessment.
Does task sharing with non-physician health-care workers improve blood pressure control in adults in low-income and middle-income countries?
Does task sharing with non-physician health-care workers improve blood pressure control in adults in low-income and middle-income countries?
Task-sharing with non-physician healthcare workers is an effective strategy for reducing blood pressure in resource-poor settings.
Supports task-sharing with non-physician workers to improve BP control in LMICs; extends evidence base for scalable hypertension strategies.
BACKGROUND: Task sharing for the management of hypertension could be useful for understaffed and resource-poor health systems. We assessed the effectiveness of task-sharing interventions in improving blood pressure control among adults in low-income and middle-income countries. METHODS: We searched the Cochrane Library, PubMed, Embase, and CINAHL for studies published up to December 2018. We included intervention studies involving a task-sharing strategy for management of blood pressure and other cardiovascular risk factors. We extracted data on population, interventions, blood pressure, and task sharing groups. We did a meta-analysis of randomised controlled trials. FINDINGS: =80%). The overall quality of evidence based on GRADE criteria was moderate for systolic blood pressure, but low for diastolic blood pressure. INTERPRETATION: Task-sharing interventions are effective in reducing blood pressure. Long-term studies are needed to understand their potential impact on cardiovascular outcomes and mortality.
