Nosocomial infections: knowledge and source of information among clinical health care students in Ghana

BACKGROUND This study determined and compared the knowledge of nosocomial infections among clinical health care students at the College of Health Sciences, University of Ghana. METHODS Two hundred undergraduate health care students from four academic programs participated in the study. The study sample was drawn from each academic program by a simple random sampling technique using the class directory from each course. The Infection Control Standardized Questionnaire (ICSQ) was used to assess the knowledge of students about three main domains, ie, hand hygiene, nosocomial infections, and standard precautions. A maximum score of 50 was obtainable, and respondents with scores ≥70% were classified as having a satisfactory knowledge. The response on each item was coded numerically to generate data for statistical analysis. Comparison of knowledge on the domains among categories of students was assessed using the Kruskal-Wallis test, while associations between courses of study and knowledge about nosocomial infections were determined using the Chi-square test. All statistical tests had a significant level of 5% (P < 0.05) RESULTS Overall mean percentage score of the participants on ICSQ was 65.4 ± 2.58, with medical, physiotherapy, radiography, and nursing students recording mean percentage scores of 70.58 ± 0.62, 65.02 ± 2.00, 64.74 ± 1.19, and 61.31 ± 2.35, respectively. The main source of information about the prevention of nosocomial infections as cited by participants was their routine formal training in class. There was no significant association (P > 0.05) between course of study and knowledge of students about preventive measures for nosocomial infections. CONCLUSION The students sampled demonstrated moderate knowledge of nosocomial infections and this was acquired largely through formal classroom training. These findings underscore the need for more emphasis on education about this important source of infection in the clinical training curriculum.
