Abstract

Background: Outbreaks of healthcare-acquired infections have been linked to contaminated medical devices such as electronic thermometers, sphygmomanometers, stethoscopes, latex gloves, masks, neckties, white coats and other.

Objective: The aim of this study was to assess non-critical healthcare tools as a potential source of healthcare-acquired bacterial infections and associated factors in public health hospitals of Harar, eastern Ethiopia from March 2016 to February 2017.

Methods: A hospital-based cross-sectional study was conducted on 212 non-critical healthcare tools owned by different health professionals. The data were collected from each owner using self-administered questionnaire. Swab specimens were collected from 187 stethoscopes and 25 sphygmomanometers using sterile cotton tips. Bacterial investigation and antimicrobial susceptibility tests were performed using standard culture tests. The data were double entered into EPI-Data version 3.1 and exported into the Statistical Package for Social Sciences version 16 for analysis.

Result: The overall prevalence of non-critical healthcare tool contamination was 53.8%. A total of 137 bacterial strains were isolated. Staphylococcus aureus was the most frequent isolate (35%). Resistance to two or more different classes of antimicrobial was found to be 19.3%. The proportion of stethoscopes or sphygmomanometers contamination owned by the health professionals who were not cleaned regularly before and after examining each patient was found to be high (77%). The majority of non-critical healthcare tools used by health professionals working in the intensive care unit were contaminated (75%) followed by medical wards (73.5%).

Conclusion: This study confirmed that the majority of the stethoscopes and sphygmomanometers were contaminated with pathogenic bacteria known to be associated with healthcare-acquired infections. Most of the healthcare workers did not practice stethoscope and sphygmomanometers disinfection. Strict and careful decontamination of stethoscopes and sphygmomanometers need to be in place before use.

Keywords: Ethiopia; Harar; Stethoscopes; healthcare-acquired bacterial infections; sphygmomanometers.
