In a recent study, we evaluated the possibility of involving non-physician health workers for non-communicable disease prevention and management in resource poor settings and demonstrated that task sharing with non-physician health workers is an effective strategy in reducing population average blood pressure.
We systematically identified evidence from well-conducted experimental studies in low and middle-income country settings and pooled outcome data on blood pressure reduction. We observed a gradient in population average blood pressure reduction with doctor-population ratio; higher the ratio better the results. Additionally, compared to community health-worker led interventions, interventions led by nurse, pharmacist or dietician were found to be more effective in reducing average blood pressure.
Consequently, we concluded that task-sharing interventions are effective in reducing blood pressure. However, long-term studies are needed to understand their potential impact on cardiovascular outcomes and mortality. Nevertheless, involving non-physician health-care workers in blood pressure control is an effective option in low-income and lower-middle income countries.
