Abstract:
PURPOSE: Many patients in South Korea are brought to hospitals by ambulance. As such, bacterial contamination within the ambulance and their critical or semi-critical equipment may be dangerous, especially for immunocompromised patients. No previous studies have examined the distribution patterns of pathogenic bacteria in ambulances or the bacterial contamination rate associated with riding in an ambulance in South Korea. The purpose of this study was to determine the distribution of pathogenic bacteria species in ambulances, and to investigate the bacterial contamination rate associated with ambulances and their equipment, in South Korea. METHODS: Thirty ambulances (17 from private facilities and 13 from regional emergency centers) were enlisted for this study. We took 955 swabs and isolated the resulting bacteria. We surveyed the intervals between cleaning and disinfecting of the ambulances and their equipment. We compared the distributional of the bacterial species, following Spaulding's classification, between critical equipment (CE), semi-critical equipment (SCE) and non-critical equipment (NCE) in the ambulances, using the chi-square test. RESULTS: The ambulances were cleaned and disinfected every 5 and 8 days, respectively. The equipment was cleaned and disinfected once every 22 and 30 days, respectively. Of the 955 swabs, 159 (16.6%) were found to be contaminated by bacteria. Fourteen pathogenic bacteria were isolated from the CE and SCE, but no methicillin-resistant or vancomycin-resistant bacteria were found. CONCLUSION: Approximately 16.6% of the ambulances and their equipment were contaminated by bacteria, and pathogenic bacteria were found on both CE and SCE. Consequently, in South Korea, we find a risk associated with the hazard presented by bacterial contamination in ambulance CE and SCE.
