The DHIS-2 data was used to assess the effect of NHIP on health service utilization, especially in terms of total visits and referral outs. The data was obtained from the DHIS-2 (Nepal’s national health information management system) through the Integrated Health Information Management Section under the Management Division, Department of Health Service (DHS) Nepal. We asked for the data on multiple variables. However, we only included few of them in our analysis based on our qualitative findings.
