Insights
Cameroon's performance-based financing (PBF) scheme had no impact on most essential medicines availability. However, PBF significantly reduced stock-outs of family planning medicines, particularly in rural areas.
Area of Science:
- Health economics
- Public health policy
- Pharmaceutical supply chain management
Background:
- Cameroon introduced a performance-based financing (PBF) scheme in 2011 to improve healthcare.
- Understanding the impact of PBF on essential medicines (EM) availability is crucial for public health.
Purpose of the Study:
- This study evaluated the effect of Cameroon's PBF intervention on the availability of essential medicines.
Main Methods:
- A randomized controlled trial was conducted across 205 health facilities in three regions.
- Data were collected at baseline (2012) and 36 months later, analyzing stock-outs over 30 days.
- Difference-in-difference regression models adjusted for covariates were used to estimate PBF's impact.
Main Results:
- The PBF intervention showed no significant effect on stock-outs for antenatal care drugs, vaccines, childhood illness drugs, or labor and delivery drugs.
- A significant 34% reduction in stock-outs of family planning medicines was observed (P=0.028).
- Effect heterogeneity was noted, with greater reductions in family planning medicine stock-outs in the North-West region and rural areas.
Conclusions:
- The PBF intervention in Cameroon had limited success in reducing overall essential medicines stock-outs.
- Partial implementation failures, including service disruptions and payment delays, likely contributed to the limited impact.
- Targeted improvements in family planning medicine availability were observed, suggesting potential for specific PBF successes.
Objective:
In 2011, the government of Cameroon launched its performance-based financing (PBF) scheme. Our study examined the effects of the PBF intervention on the availability of essential medicines (EM).
Methods:
Randomised control trial whereby PBF and three distinct comparison groups were randomised in a total of 205 health facilities across three regions. Baseline data were collected between March and May 2012 and endline data 36 months later. We defined availability of multiple EM groups by assessing stock-outs for at least one day over the 30 days prior to the survey date and estimated changes attributable to PBF using a series of difference-in-difference regression models, adjusted for relevant facility-level covariates. Data were analysed stratified by region and area to assess effect heterogeneity.
Results:
Our estimates suggest that PBF intervention had no effect on the stock-outs of antenatal care drugs (P = 0.160), vaccines (P = 0.396), integrated management of childhood illness drugs (P = 0.681) and labour and delivery drugs (P = 0.589). However, the intervention was associated with a significant reduction of 34% in stock-outs of family planning medicines (P = 0.028). We observed effect heterogeneity across regions and areas, with significant decreases in stock-outs of family planning products in North-West region (P = 0.065) and in rural areas (P = 0.043).
Conclusions:
The PBF intervention in Cameroon had limited effects on the reduction of EMs stock-outs. These poor results were likely the consequence of partial implementation failure, ranging from disruption and discontinuation of services to limited facility autonomy in managing decision-making and considerable delay in performance payment.
