A systematic review of healthcare-associated infections in Africa: An antimicrobial resistance perspective.

BACKGROUND

Healthcare-associated infection (HCAI) is a global health challenge, not only as an issue of patient safety but also as a major driver of antimicrobial resistance (AMR). It is a major cause of morbidity and mortality with economic consequences.

OBJECTIVE

This review provides an update on the occurrence of HCAI, as well as the contribution of emerging AMR on healthcare delivery in Africa.

METHODS

We searched PubMed, Cochrane database, African Journals Online and Google Scholar for relevant articles on HCAI in Africa between 2010 and 2017. Preferred reporting items of systematic reviews and meta-analyses guidelines were followed for selection. Thirty-five eligible articles were considered for the qualitative synthesis.

RESULTS

Of the 35 eligible articles, more than half ( = 21, 60%) were from East Africa. spp., and spp. were the common pathogens reported in bloodstream infection, (catheter-associated) urinary tract infection, surgical site infection and healthcare-associated pneumonia. Among these various subtypes of HCAI, methicillin-resistant (3.9% - 56.8%) and extended-spectrum beta-lactamase producing Gram-negative bacilli (1.9% - 53.0%) were the most reported antimicrobial resistant pathogens.

CONCLUSION

This review shows a paucity of HCAI surveillance in Africa and an emergence of AMR priority pathogens. Hence, there is a need for a coordinated national and regional surveillance of both HCAI and AMR in Africa.
