Context: Bihar aims to achieve a maternal mortality ratio (MMR) of less than 70 per 1, 00, 000 live births, towards achieving its Sustainable Development Goal. The same can be achieved through robust monitoring of the health programs in the state. The present study critically analyses the use of a mobile-based reporting system on achieving the SDG for the state. Aims: The study aims to assess the use of mobile phone-based reporting systems for Sustainable Development Goals. Thus, establishing the usefulness of a mobile-based reporting system. The study also explores the cost of running the project. Settings and Design: It is a quasi-experimental design. The study was conducted with Front Line Workers (FLW -Accredited Social Health Activist & Auxiliary Nurse Midwife) of two intervention blocks in the Saharsa District of Bihar. The two blocks were using mobile phones for reporting RMNCHA services. A total of 109 FLWs were contacted in Jul 2017. Methods and Material: Quantitative methods were used in the study. Two tools were administered to the respondents at the facility level. Statistical Analysis Used: The study compares the increase in the utilization of health care services from FY 13-14 to FY 16-17. The case is defined as the block in which the front-line workers use mobile phones for reporting and control is where the reporting is through paper-based mode. To arrive at a net difference, the study used the difference in a different technique to analyse the data. Data were obtained from the government reporting system. To corroborate the results, the mean values were calculated, by dividing the blocks of the district into two groups case and control. The step-down costing of the project was performed to arrive at the unit cost of implementation.
