Non-pharmacological interventions significantly reduce surgical site infections.

A systematic review of 11 studies revealed that non-pharmacological interventions in Sub-Saharan Africa significantly decrease surgical site infections (SSI) by 15% to 95%. These interventions included improving adherence to protocols, policy changes, and implementing multimodal strategies. The effectiveness of these approaches varied based on patient characteristics, surgical urgency, and healthcare settings. Notably, multimodal interventions emerged as the most comprehensive and effective method in reducing SSI rates across various surgical populations.
