High-Fidelity Simulation Curriculum for Training Residents in Noninvasive Respiratory Support.

Background

The coronavirus disease (COVID-19) pandemic highlighted the importance of physicians managing patients with noninvasive respiratory support (NIRS), including noninvasive ventilation (NIV) and high-flow nasal cannulas (HFNCs), emphasizing the need for thorough education on these modalities.

Objective

To determine the effect of a novel simulation-based curriculum on improving the equipment familiarity and understanding of the physiology and application of NIRS among internal medicine residents.

Methods

The curriculum consisted of a didactic session on the clinical application of NIRS, a case-based scenario on NIV using high-fidelity simulation, and a debrief session. Learners filled out surveys before and after the session to evaluate changes in objective knowledge of and subjective comfort with NIRS. P values were calculated using independent two-sample t tests.

Results

Most residents (85.6%; n = 101) confirmed never having received a formal training in NIRS. At baseline, 34.7% (n = 41) and 24.6% (n = 29) felt "comfortable" or "very comfortable," respectively, using NIRS, which improved to 91.5% (n = 108) and 89% (n = 105) after the session (P = 0.001). A statistically significant improvement in clinical knowledge was demonstrated after the session (P < 0.05), with residents correctly recognizing all three indications for bilevel positive airway pressure (BiPAP) (87.2% to 98.3%, 56% to 67.8%, and 21.2% to 55.1%), contraindications to BiPAP (81.4% to 90.7%), appropriate adjustment of BiPAP (30.5% to 73.7%), and HFNC settings (68.6% to 79.7%). Following the curriculum, postgraduate year (PGY)-1 (PGY-1)s' knowledge was increased beyond the baseline of the PGY-2/3s who trained in New York during the pandemic (mean score change 50.6% to 72.1% for PGY-1s, 61.5% to 75.7% for PGY-2/3s). Three-month retention surveys revealed consistent learner satisfaction and learner retention in all aspects.

Conclusion

Our 1-hour high-fidelity simulation-based curriculum significantly enhanced medical residents' knowledge, skills, and confidence in using NIRS for acute respiratory failure, with particularly notable benefits for those in the early years of training. Such a simulation-based curriculum could potentially lead to better hospital resource allocation and improved patient outcomes.
