House-To-House Survey vs. Snowball Technique for Capturing Maternal Deaths in India: A Search for a Cost-Effective Method‪.‬

Background & objectives: Estimation of maternal mortality has been difficult because of large sample size requirement. A study using snowball technique for identification of households where maternal death has taken place and its related causes was conducted. We present here the feasibility of carrying out the snowball technique for capturing maternal deaths as against house-to-house survey and to obtain the estimates of maternal mortality ratio (MMR) in some selected States of India. Methods: Five states representing high MMR (Uttar Pradesh), medium MMR (Maharashtra, Karnataka, Uttranchal) and low MMR (Delhi) were selected. A total of 8 PHCs and 3 (UFS) were covered. Study used both house-to-house survey and snowball technique to enumerate the maternal deaths in the selected PHCs in rural area and urban frame survey (UFS) in urban area.
