Abstract
Health care-associated infections (HAIs) are a major threat to patient safety and quality care. However, they are avoidable by implementing evidence-based infection prevention and control (IPC) measures. This review evaluated the evidence of the effectiveness of IPC interventions in reducing rates of HAIs in health care settings in Africa. We searched several databases: CENTRAL, EMBASE, PUBMED, CINAHL, WHO IRIS, and AJOL for primary studies reporting rates of the 4 most frequent HAIs: surgical site infections, central line--associated bloodstream infections, catheter-associated urinary tract infections, ventilator-associated pneumoniae, and increase in hand hygiene compliance. Two reviewers appraised the studies and PRISMA guidelines were followed. Out of 4,624 studies identified from databases and additional sources, 15 studies were finally included in the review. Themajority of studies were of pre- and post-test study design. All the studies implemented a combination of interventions and not as stand-alone components. Across all included studies, an improvement was reported in at least 1primary outcome. Our review highlights the potential of IPC interventions in reducing HAIs and improving compliance with hand hygiene in health care facilities in Africa. For future research, we recommend more pragmatic study designs with improved methodological rigor.
