Problem-Based Learning Strategy Effect on Nurses' Knowledge and Patients' Health Behaviour Outcomes Post Myringoplasty

Abstract

Myringoplasty is a repair of tympanic membrane perforation to restore and improve hearing function. Health belief model (HBM) is the suggested tool to measure the effect of post-operative instructions using problem-based learning strategy on patients' to maintain hearing and health behaviour. A well prepared nursing staff provides long lasting instructions for patients. The study aimed to evaluate the effect of problem-based learning strategy on nurses' knowledge and patients' health behaviour outcomes post myringoplasty. Research design: A quasi-experimental research design was utilized to meet the aim of this study. Setting: The study was conducted in Aswan University Hospital at the Department of Ear Nose and Throat. Sample: all available nurses (30 nurses) who have been working in the study setting, and 60 adult patients admitted at the time of the data collection were included in the study setting. Three tools were used for data collection, tool (1): Assessment of nurses' knowledge sheet developed by the researcher, and tool (2): HBM sheet according to Ruba etal. (2016), tool (3):  assessment of patient complications sheet developed by the researcher. Results: in the present study, findings significant correlation of pre-operative nurses knowledge related to pre and post learning strategy P-value < 0.05. In addition there were a highly significant correlation of post-operative nurses knowledge related to pre and post learning strategy P-value< 0.001. As regard to health belief model there was significant correlation between pre learning strategy, post one month & after three months of post-operative instructions, in relation to HBM. Conclusion: Nurses' knowledge and skills differed with respect to the mean score. Introducing of problem-based learning strategy and hand out booklet were effective in improving the level of nurses’ knowledge regarding post-operative instructions of patients with myringoplasty. Notably it revealed that, satisfactory patients' outcomes post applying the strategy in relation to HBM. Recommendations: All nurses should be aware by instructions that given to patients' pre discharge and inform patients about them.
