Pakistan is host to one of the most protracted refugee situations in the world with some 1.3 million registered Afghan refugees in the country. Under current policies, refugees and Afghans are included in the national health system at the same conditions and costs as Pakistani nationals. There is a lack of disaggregated health data on refugees, leading to difficulties in monitoring refugee health status, access, and utilization of health services. To get a better picture and inform internal programming, UNHCR commissioned a health and utilization survey (HAUS), to measure health outcomes and access to health services for refugees in Pakistan. In addition, the survey assessed levels of knowledge of available healthcare services, identified barriers to access to healthcare and evaluated the impact of the discontinuation of the parallel health system on refugee communities. The survey was undertaken prior to the 2022 floods and therefore does not reflect the impact thereof.
