It is incumbent on residency training programs to teach evidence-based strategies of mechanical ventilatory support to medical residents. Nonetheless a pervasive lack of satisfaction exists among resident physicians in the understanding of mechanical ventilation. We describe an effective model of mechanical ventilation education for in-training physicians.
We employed a 10 item questionnaire in multiple choice format that was administered twice to 24 medical residents, before and after a one hour tutorial on mechanical ventilation.The residents were equally distributed among the PG1, PG2 and PG3 years. The tutorial comprised a lecture with graphic display of mechanical ventilator waveforms, discussion of respiratory mechanics, recognition and management of mechanical ventilator related complications and concepts regarding settings for conventional modes of mechanical ventilation. All participants completed all parts of the pre-test and post-test questionnaires.
The post-test scores of all resident physicians improved substantially compared with the pre-test scores. The mean score on the pre-test was 5.1 (± 1.6 SD), while on post-test it was 6.4 (± 1.2 SD)[Signed Rank Test, p < 0.0001](add figures). Moreover, the smaller standard deviation of the mean post-test score meant that fewer scores were in the low range.
We provide a design of enhancing clinical competence in mechanical ventilatory support which can be applicable to all levels of residents in the training program. Effective methods of mechanical ventilation strategies can reduce the mortality, duration of ICU stay, complications and healthcare costs.
Clinical instructors of mechanical ventilation should update their curriculum to incorporate an effective teaching method such as suggested in this study. This method should be implemented at the begining of the monthly ICU rotation to provide the residents with a comprehensive ICU experience.
