Baseline Characteristics of a Cluster Randomized Controlled Trial Targeting Hand Hygiene in Primary Healthcare in Burkina Faso and Mali.

OBJECTIVES

This study presents baseline characteristics of a cluster randomized controlled trial (cRCT) on hand hygiene in primary healthcare in Burkina Faso and Mali, addressing data gaps on hand hygiene practices in these settings.

METHODS

We implemented a two-arm cRCT in 48 primary healthcare facilities. Baseline data were collected (January-June 2023), followed by covariate-constrained randomization. We conducted covert hand hygiene observations, hand-rinse sampling for detection, and a survey on behavioral factors among healthcare workers. The primary outcome is observed handwashing rate.

RESULTS

Baseline data included 309 healthcare workers. Trial arms were balanced in hand hygiene adherence, behavioral factors, and contamination. Hand hygiene adherence was low (12%). contamination was very high in Burkina Faso (76%) and considerable in Mali (23%). Participants had a high intention to wash their hands (93%) but only a quarter could name all moments for hand hygiene.

CONCLUSION

Poor hand hygiene and contamination in our setting may heighten nosocomial infection risks. Interventions should address knowledge and build on high intentions to perform hand hygiene.
