RESUMO
Government of India introduced National Rural Health Mission in 2005-now transformed into National Health Mission (NHM), to bring about architectural reforms in health sector. In this study, we evaluate the overall impact of NHM on infant mortality at national and state level. Annual data on infant mortality rate (IMR) from 1990 to 2016 were obtained from Sample Registration System bulletins. With reporting year 2009 considered as cut-off point, a two-step segmented time series regression analysis was conducted. Estimates of pre-slope, post-slope and change at the point of intervention were computed by applying auto-regressive integrated moving average (1, 0, 0) while adjusting for trend and auto correlation. We found that while IMR reduced from around 80 to 34 per 1000 live births at the national level from 1990 to 2016, the annual rate of reduction increased from 1.6 per 1000 live births before NHM to 2.2 per 1000 live births after NHM. This is estimated to have averted 248,212 infant deaths in India, between 2005 and 2017. The rate of decline in IMR accelerated in 13 out of 17 larger states, most significantly in Andhra Pradesh, Gujarat, Assam, Haryana, Punjab and Uttar Pradesh. NHM has thus been successful in accelerating the overall rate of reduction in IMR in India. There is still a need to identify the determinants of variations at state level. We recommend strengthening of NHM in terms of funding and implementation.
