Abstract
A computerized decision support program for isolation precaution was developed based on a conceptual framework of the problem-solving process for appropriate isolation precaution measures by certified nurses in infection control (CNICs). This study evaluated the effectiveness of the program for infection control practices of novice CNICs and health care-associated infections (HAIs). A randomized controlled trial was conducted with 187 novice CNICs. Finally, 28 CNICs participated after providing informed consent. The baseline and intervention periods were from January to April 2012 and from May to August 2012, respectively. The experimental group was asked to use the computerized decision support program in their infection control practices during the intervention period. Data of infection control practices and HAIs were collected from both groups. No significant differences in the incidence rate of methicillin-resistant Staphylococcus aureus (MRSA) and Clostridium difficile infection (CDI) and number of outbreaks were found between the 2 groups. The program was used for 92 HAI cases and was considered helpful in 72 cases. Based on the analysis of descriptive data, the program was useful for novice CNICs in infection control practices for risk assessment of infection, decision and implementation of isolation precautions, support for decision making, and as a reference and educational tool.
