In 2013, the German-Cambodian Social Health Protection Project (SHPP) implemented by GIZ commissioned a survey to gather evidence on the effectiveness and efficiency of integrated social health protection schemes (ISHPS) for the poor on the utilisation of health services and associated financial protection, in four GIZ-supported operational districts (ODs). A first round of data collection was conducted between November 2013 and March 2014, with a second round planned for 2014-2015. Due to the similar objectives of this survey with the WB-initiated HEF Utilization Survey, GIZ and WB agreed to cooperate on producing similar instruments, sampling, data collection and analysis for the two studies, fielded simultaneously in 2015. It thus enabled a comparison of these GIZ-supported schemes with other HEFs in Cambodia, as well as the initial baseline.
After winning the public bid for the HEF Utilization Survey, Angkor Research was awarded the contract for the Complementary Survey from GIZ. Angkor Research was responsible for all components of the data collection and data management, including: initial research design and literature review; sampling methodology, framework and selection (including longitudinal matching of baseline households); instrument design, translation and pre-testing; national ethical approval (NECHR); field data collection; data entry and data management; transcription, translation and coding of all qualitative data; quantitative and qualitative data analysis; and report writing.
The Complementary Survey was also longitudinal, with tracking and follow-up interviews with baseline respondents. The quantitative household survey was conducted with 1,889 households, with a two-tiered control arm, and segregated by distance to the nearest public health facilities. Care was taken to ensure alignment of all survey instruments and sampling procedures between the two projects, and with the previous baseline survey. Additional qualitative in-depth interviews (IDIs) were conducted with 56 key informants including ISHP members, HEF operators, public hospital/health center directors and doctors, and village health support group volunteers. The quantitative household survey was conducted among 1,745 households, including 1,521 households matched from the baseline. The response rate was 92.4%, and individual interviewers completed an average of 5.8 interviews per day.
