Plain English Summary

Background and study aims
This study will evaluate the impact of results-based financing (RBF) on priority maternal and child health services in rural districts of Zambia. RBF is an output-based financing mechanism where the health providers receive financial incentives on achieving a pre-agreed set of services upon verification of the achieved results. The overall objective of the HRBF is to increase access to, and the use of, key maternal and child health interventions. The impact evaluation will generate valuable evidence to determine whether this goal is attainable under the proposed policies. In addition, the impact evaluation will contribute to the government’s intentions to strengthen Central and Province-level capacities for evidence-based policy and program management for improving maternal and child health (MCH).The study will address the following three primary research questions: (a) What is the causal effect of the Zambian HRBF on the population health indicators of interest specifically on maternal and child health? (b) Do higher incentive payments in rural/remote areas result in increased health outcomes and greater retention of staff? (c) How does the likelihood of audit/external verification of results affect the accuracy of reported data?

Who can participate?
Participating health facilities from 30 rural districts triplet-matched on key health systems and outcome indicators and randomly allocated to three arms with ten districts per arm.

What does the study involve?
This study tests the effectiveness of RBF in comparison with input (equivalent) financing, and business-as-usual. Within each rural province, a triplet of districts with similar characteristics has been selected. Thus, 30 rural districts (10 triplets) have been selected from all rural provinces in the country. Within each matched triplet, districts have been randomly allocated to implement one of the three interventions (RBF, equivalent financing or business-as-usual). All health facilities (excluding private-for-profit) in these 30 districts participate in this study. Health facilities within the RBF intervention will receive RBF incentives every quarter conditional on their performance on a set of indicators related to maternal and child health. The facilities will receive incentives on achieving quantity (volume of services) and quality (adherence to national standards of care). Remote facilities in addition will receive a remoteness bonus. Health facilities within the equivalent financing intervention will receive resources matching with the RBF incentives. However, these resources will not be conditional on performance. Health facilities within the business-as-usual intervention will not receive any additional resources or inputs. The study measures the outcomes of the interventions at the population and health facility levels. The outcomes will be measured through two rounds of surveys involving health facilities and households within the catchment areas of these facilities selected for this intervention. The first round of survey was completed before the interventions were implemented and the second round of survey will be undertaken after the completion of the implementation. The study will also employ qualitative surveys and cost-effectiveness analysis.

What are the possible benefits and risks of participating?
Health facilities in the RBF intervention and the equivalent financing groups will benefit from financial resources tied with performance and not conditional on performance, respectively. There are no adverse effects or risks of this intervention.

Where is the study run from?
There are 523 health facilities from 30 rural districts participating in this study. The implementing agency is the Ministry of Health, Zambia.

When is study starting and how long is it expected to run for?
The intervention started in April 2012 and is expected to continue until July 2015.

Who is funding the study?
Governments of Norway and the UK through the Health Results Innovation Trust Fund administered by the World Bank.

Maternal and child health


Health facilities within RBF districts will receive incentives every quarter based on attaining:
