Healthcare-associated infections in Africa: a systematic review and meta-analysis of point prevalence studies.

The pooled point-prevalence of HAIs in Africa is more than two times higher than the rate reported in developed countries. The prevalence varied between the countries and was highest in the ICU and neonatal ICU/ward. Surgical site infection and bloodstream infection were the most common HAIs reported in African studies. Recent hospitalization, presence of peripheral vascular catheter and having diabetes mellitus were the strongest predictors of HAIs in African studies. Most of the HAIs are preventable with appropriate infection control measures and antimicrobial stewardship. Additional studies are needed especially in the Central African region. Future studies should be designed using standardized protocol and standardized definition to reduce heterogeneity among the studies.
