Using Online Simulation of Pediatric Musculoskeletal Cases to Evaluate How Knowledge of Costs Affects Diagnostic...

Rising healthcare costs have emphasized the need to teach cost-conscious care in graduate medical education.

To teach high-value care and diagnostic evaluation of pediatric musculoskeletal complaints to residents and rotating medical students through online cases.

Six online cases were developed and tested at the University Hospitals Cleveland Medical Center. Learners completed modules in one of two groups, those who saw itemized costs of diagnostic tests or those who did not. All learners completed a post-simulation survey. Measured outcomes included presumed diagnosis, cost of evaluation, tests ordered, and perceptions toward high-value care. Simulation outcomes were assessed using paired t-tests. Survey data was analyzed with Chi-squared tests. Outcomes separated by training year were analyzed using ANOVA and post-hoc Tukey test.

Thirty-nine residents and medical students participated and were randomly assigned to complete the cases with costs (n = 19) or no costs (n = 20) displayed during workup. Overall, learners who saw costs spent less money on diagnostics ($1511.11 mean per learner versus $2311.35, p = 0.01). Arrival at the correct diagnosis was associated with lower costs in 3 of 6 cases. When compared to the no cost group, learners in the costs group reported feeling more knowledgeable about the price of diagnostic tests (p = 0.04) and were more likely to factor costs into their practice moving forward (p = 0.03). Third year or above residents demonstrated a statically significant increase in correctly diagnosed cases as opposed to medical students.

Interventions that challenge learners to integrate costs into decision-making can potentially change future practice.
