The critical role of infection prevention overlooked in Ethiopia, only one-half of health-care workers had safe practice: A systematic review and meta-analysis

Abstract

Background: Effective infection prevention and control measures, such as proper hand hygiene, the use of personal protective equipment, instrument processing, and safe injection practicein the healthcare facilitiesare essential elements of patient safety and lead to optimal patient outcomes. In Ethiopia, findings regarding infection prevention practices among healthcare workers have been highly variable and uncertain. This systematic review and meta-analysis estimates the pooled prevalence of safe infection prevention practices and summarizesthe associated factors among healthcare workers in Ethiopia.

Methods: PubMed, Science Direct, Google Scholar, and the Cochran library were systematically searched. We included all observational studies reporting the prevalence of safe infection prevention practices among healthcare workers in Ethiopia. Two authors independently extracted all necessary data using a standardized data extraction format. Qualitative and quantitative analyseswere employed. The Cochran Q test statistics and I2 tests were used to assess the heterogeneity of the studies. A random-effects meta-analysis model was used to estimate the pooled prevalence of safe infection prevention practice.

Results: Of the 187 articles identified through our search, 10 studies fulfilled the inclusion criteria and were included in the meta-analysis. The pooled prevalence of safe infection prevention practice in Ethiopia was 52.2% (95%CI: 40.9-63.4). The highest prevalence of safe practice was observed in Addis Ababa (capital city) 66.2% (95%CI: 60.6-71.8), followed by Amhara region 54.6% (95%CI: 51.1-58.1), and then Oromia region 48.5% (95%CI: 24.2-72.8), and the least safe practices were reported from South Nation Nationalities and People (SNNP) and Tigray regions with a pooled prevalence of 39.4% (95%CI: 13.9-64.8). In our qualitative syntheses, the odds of safe infection prevention practice were higher among healthcare workers who had good knowledge and a positive attitude towards infection prevention. Also, healthcare workers working in facilities with continuous running water supply, having infection prevention guideline, and those received training were significantly associated withhigher odds of safe infection prevention practice.

Conclusions: Infection prevention practices in Ethiopia was poor, with only half of the healthcare workers reporting safe practices. Further, the study found out that there were regional and professional variations in the prevalence of safe infection prevention practices. Therefore, the need to step-up efforts to intensify the current national infection prevention and patient safety initiative as key policy direction is strongly recommended, along with more attempts to increase healthcare worker's adherence towards infection prevention guidelines.
