The aim of this study was to determine whether a structured workshop for nurses promoting best practice technique for management of indwelling urinary catheters results in an improvement in knowledge on the subject. A one-group pre-post test quasi-experimental design using a convenience sample was used. Nurses attended a workshop utilizing interactive lecture approaches, and based on best practice technique for the management of indwelling urinary catheters. Participants (n = 30, 55% of those invited) completed a multiple choice question (MCQ) test, derived from topics to be covered in the workshop, prior to the intervention. The MCQ test was repeated after the workshop to assess retention and application of knowledge. There was a significant improvement in mean test scores after the workshop when compared with pre-workshop scores (mean = 16 center dot 9, SD = 1 center dot 1 vs. mean = 8 center dot 5, SD = 1 center dot 7, p < 0 center dot 001). It is concluded that interactive lecture workshops based on best practice techniques for the management of urinary catheterization help improve nurses' knowledge. Such educational initiatives also help to overcome deficiencies in initial nurse training where preparation for quality catheter care can be lacking. Within the limitations of a small-scale single-group study of a convenience sample, the information gained in this study will be valuable in helping to establish a baseline for further research. It may also help guide improvements in the implementation of policies for improved management of the care provided to people with an indwelling urinary catheter with the ultimate goal of enhancing safe and quality patient care.
