Assessment of knowledge and practices of healthcare workers towards infection prevention and associated factors in healthcare facilities of West Arsi District, Southeast Ethiopia: a facility-based cross-sectional study

Abstract

Abstract Background The prevention of healthcare associated infections is central to the provision of safe, high quality healthcare. Infections acquired in healthcare facilities are a major public health concern, contributing to increased morbidity, mortality, and cost in both developed and developing countries. Although most of these infections can be prevented with relatively inexpensive infection prevention and control measures in many developing countries, in sub-Saharan African healthcare facilities have no effective infection prevention programs. Additionally, there is limited information on healthcare worker infection prevention knowledge and practice in countries such as Ethiopia. The aim of this study was to assess the knowledge and practices of healthcare workers with respect to infection prevention and associated factors in healthcare facilities in southeast Ethiopia. Methods A facility-based cross-sectional study design was used to study healthcare workers in the southeast, Ethiopia. Multi-stage sampling was employed to select 680 healthcare workers from 30 randomly selected healthcare facilities. Data was collected using a self-administered structured questionnaire. Descriptive statistics were computed. Multivariable logistic regression was performed to identify factors associated with healthcare workers infection prevention knowledge and practice. Results A total of 648 healthcare workers participated in this study, for a response rate of 95.3%. Of these, 53.7% (95% CI: 49.8, 57.4%) and 36.3% (95% CI: 32.4, 40.1%) of the respondents were assessed as knowledgeable and reported safe infection prevention practices respectively. The likelihood of self-reporting safe infection prevention practice significantly increased if healthcare workers had received training (AOR = 5.31; 95% CI: 2.42,11.63) and had infection prevention guidelines available (AOR = 3.34; 95% CI: 1.65, 6.76). Healthcare workers were more likely to have infection prevention knowledge if they worked longer ten years or more (AOR = 3.41; 95% CI: 1.22, 9.55); worked in facilities with infection prevention committees (AOR = 1.78; 95% CI: 1.01, 3.13), had infection prevention guidelines available (AOR = 2.44; 95% CI: 1.45, 4.12); had training (AOR = 5.02; 95% CI: 1.45, 8.59). Conclusions Inadequate infection prevention knowledge and unsafe practices were frequent among study participants, reflecting a potentially common problem at public healthcare facilities in southeast Ethiopia. Healthcare workers have better knowledge and safer practices if they had received infection prevention training and had infection prevention guidelines in their workplace. Interventions should be designed to consider these identified factors.
