Health Results-Based Financing Impact Evaluation 2012
Baseline Household Survey
Central African Republic
Scaling-up of performance-based financing (PBF) has never been systematically evaluated in Central African Republic (CAR) on any meaningful scale. As such, this Impact Evalution's larger policy objectives are to:
(a) identify the impact of PBF on maternal and child health (MCH) service coverage and quality,
(b) identify key factors responsible for this impact, and
(c) assess cost-effectiveness of PBF as a strategy to improve coverage and quality.
In doing so, the results from the impact evaluation will be useful to designing national PBF policy in CAR and will also contribute to the larger body of knowledge on PBF. The evaluation will rely on two main sources of data:
1. Household surveys: A household survey will be implemented at baseline (i.e., before implementation of PBF begins), and at endline (i.e., after PBF has been implemented for two years).
2. Facility-based surveys: A facility-based survey will be implemented at baseline and at endline.
The main targeted outcomes fall into two main groups:
(a) Maternal and Child Health Service coverage indicators and
(b) Quality of care indicators.
The study is a blocked-by-region cluster-randomized trial (CRT), having a pre-post with comparison design. The team relied primarily on experimental control to answer the main research questions for this study. The study will also include a qualitative component at endline to probe deeper for explanations or explore specific issues that are relevant to PBF.
Note: The Health Facility Baseline Survey is available online under Impact Evaluation Surveys Collection. The study is titled "Central African Republic Health Results-Based Financing Impact Evaluation 2012, Health Facility Baseline Survey."
Kind of data
Sample survey data [ssd]
Seven prefectures in the 2nd, 3rd, 4th and 6th regions of CAR covering a total population of approximately 2.5 million.
Unit of analysis
The target population for the household baseline survey is households with at least one pregnant woman or a woman with a child who was born during the two years preceding the survey.

To select the households, a catchment area was established for each of the 97 Health Centers and 145 Health Posts. No more than 20 households were randomly selected for survey in the catchment area of each selected health facility.
Since the study was a cluster-randomized trial, the sample size estimation had to take into account design effects. In total, there were approximately 242 clusters defined by Health Centers and Health Posts (i.e., each facility constitutes a cluster) and at least 80 health facilities in each of the three study groups. This tally does not include the 9 prefecture hospitals which were not to be randomly assigned.
The survey was administered to women in sampled households who have delivered a baby within the two years preceding the survey. In addition, the survey teams weighed and measured the height of all children aged under 5 years, mothers of children less than 2 years, and pregnant women who were present in the household during the survey team's visit.
Dates of collection
Mode of data collection
The household questionnaire is composed of two parts: the first is a household survey for all members of the household, while the second part is specifically for women between 15-49.
In addition to the questionnaires, the survey teams did the following:
- Weigh and measure the height of all children aged under 5 years, mothers of children less than 2 years, and pregnant women who were present in the household during the survey team's visit.
