Effect of specific training course for competency in professional oral hygiene care in the intensive care unit: a quasi-experimental study for developing a standardized learning curve.

ABSTRACT

BACKGROUND: The development of evidence-based training standards can help improve the quality of educational programs for novice intensive care unit (ICU) nurses. This study was conducted to assess the application of a training course on competency development of nurses in relation to oral hygiene care in ICU patients and to develop a checklist for evaluating the competence performance. In addition, to achieve a certain level of oral hygiene competence, as well as to assess the relative importance of predicting factors and learning competency patterns in oral hygiene care, we used standard learning curve. METHODS: This quasi-experimental study with time series design was conducted on newly registered ICU nurses of a teaching hospital affiliated with Tehran University of Medical Sciences, Iran, between 2016 and 2018. In the first phase of this study, we designed a checklist to assess nurses' professional competence in oral hygiene care in three stages before, during, and after care. Then, in the second phase, the level of competence of nurses in repeated times of oral hygiene care was determined based on checklist items and recorded in the learning curve. RESULTS: The greatest increase of oral hygiene care competency due to repetition was observed in the first and fourth times of repetition in comparison to the subsequent and previous steps. In the linear regression model, demographic variables predicted 12-19% of changes related to skill scores in repetitions. CONCLUSION: According to the learning curve, newly registered ICU nurses can reach an acceptable competency after 6 repetitions of oral hygiene care.
