Does home-based screening improve hypertension diagnosis, treatment and control? A regression discontinuity analysis in urban India
As part of India’s efforts to expand primary healthcare services, several state governments are implementing or considering home-based hypertension screening programmes to improve population-wide diagnosis and blood pressure (BP) control rates. However, there is limited evidence on the effectiveness of home-based screening programmes in India. Using six waves of population-representative cohort data (N=15574), we estimate the causal effect of a h…
