The article recently published by TT Aye et al. (2024) in Health Policy and Planning is a major contribution to understanding the medium-term (5 years) effects of the free healthcare policy introduced in 2016 in Burkina Faso. The study makes rigorous use of interrupted time series with a non-equivalent control group and presents a wealth of information on the methodology used. Remarkably, numerous sensitivity analyses were conducted to strengthen the credibility of the results and limit the risk of bias.Three salient conclusions are presented: (1) free healthcare had no effect on the proportion of pregnant women who gave birth in a health center, either immediately or after 5 years; (2) free healthcare led to an immediate and significant increase in the rate of consultations for children <5 years of age and; (3) after this immediate increase, free healthcare led to a gradual decrease in the rate of consultations for children <5 years in the medium term. We believe it is essential to highlight some important nuances regarding these conclusions and highlight some methodological issues.
