Pre-referral rectal artesunate: no cure for unhealthy systems

Pre-referral rectal artesunate suppositories can save the lives of children with severe malaria if patients receive adequate post-referral care. A multi-country randomised controlled trial reporting on the efficacy of rectal artesunate informed the current WHO guidelines. In October, 2022, we reported on the findings of the Community Access to Rectal Artesunate for Malaria (CARAMAL) project, a carefully monitored roll-out of quality-assured rectal artesunate into established community-based health-care systems in DR Congo, Nigeria, and Uganda. The aim of the project was to understand the challenges involved in the successful real-world implementation of pre-referral rectal artesunate and to inform subsequent scale-up in endemic countries. In our study, we found that children treated with pre-referral rectal artesunate in routine clinical practice did not have an increased chance of survival, most likely explained by shortfalls along the continuum of care. A substantial proportion of the more than 6200 severely ill children that were followed up 28 days after treatment initiation did not receive comprehensive severe malaria care, either due to an incomplete referral to a secondary facility, or due to incomplete post-referral treatment. The observational study design allowed for a realistic assessment of the obstacles involved in implementing pre-referral rectal artesunate in settings where malaria mortality remains high. Without improving the entire continuum of care, children will continue to die from severe malaria and promising interventions will fail to meet their full potential.
