An evaluation of infection control in private and public sector intensive care units in South Africa.

ABSTRACT

BACKGROUND: Appropriate infection control policies and practices are key to reducing the risk of healthcare-associated infections in patients in intensive care units (ICUs). OBJECTIVE: To evaluate infection control in ICUs using the Infection Control Assessment Tool (ICAT). METHODS: Six public and five private adult ICUs were included. Seven modules from the ICAT were administered including ICU, hand hygiene, and isolation and standard precautions. Modules were scored on a quantitative scale as per the tool guidelines and trained independent nurses observed practices. RESULTS: All ICUs reported to have a 11 nurse-to-patient ratio. One public ICU did not have the required 12 hand wash basin-to-bed ratio. We observed 100% adherence to handwashing or alcohol rub at each of the five moments of hand hygiene; however, the correct amount of alcohol rub was used in only 2% (n = 2) of the 117 observations. The median score for isolation and standard precautions was 79%. DISCUSSION: There was good infection control practice in ICUs. However, ICUs did not have isolation policies for all the infections listed in the ICAT and did not screen visitors to the ICU. We identified shortcomings in the ICAT and a more suitable tool is required for our healthcare setting.
