Implementation of an educational module on nosocomial infection control measures: a randomised hospital-based trial

摘要

Previous cross-sectional studies have reported limited knowledge and practices among nurses regarding controlling nosocomial infections (NIs). Even though health institutions offer many irregular in-service training courses to solve such issues, a three?year-nursing educational programme at institutions is not adequate to enable nurses to handle NIs. Therefore, this study aims to evaluate the implementation of an educational module on NIs control measures among Yemeni nurses. A single-blinded randomised hospital-based trial was undertaken involving 540 nurses assigned to two intervention groups and a waitlist group. Intervention group-1 received a face-to-face training course comprising 20?h spread over six?weeks and a hard copy of the module, while intervention group-2 only received the hard copy of the module “without training”. In contrast, the waitlist group did not receive anything during the period of collecting data. A self-administered NI control measures-evaluation questionnaire was utilised in collecting the data from the participants; before the intervention, at six?weeks and 3?months after the end of the intervention. The period of data collection was between 1st May and 30th October 2016. The results from collecting and analysing the data showed a statistically significant difference in the mean knowledge scores between the intervention groups that were detectable immediately post-intervention with a mean difference (MD) of 4.31 (P??0.001) and 3?months after the end of the intervention (MD?=?4.48, P??0.001) as compared to the waitlist group. Similarly, the results showed a statistically significant difference in the mean practice scores between the intervention groups immediately post-intervention (MD?=?2.74, P??0.001) and 3?months after the intervention (MD?=?2.46, P??0.001) as compared to the waitlist group. Intervention-1 (face-to-face training module) was more effective than intervention-2 (module only) in improving Yemeni nurses’ knowledge and practices regarding NI control measures compared to the waitlist group. The findings of this study found that intervention-1 could be offered to nurses in the form of an in-service training course every six?months. The NI course should also be included in nursing curricula, particularly for the three-year-nursing diploma in Yemen. Nosocomial infection educational module for nurses ISRCTN19992640 , 20/6/2017.
