Clinical Pathway Adherence and Missed Diagnostic Opportunities Among Children with Musculoskeletal Infections

INTRODUCTION

Clinical care pathways (CPs) integrate best evidence into the local care delivery context to promote efficiency and patient safety. However, the impact of CPs on diagnostic performance remains poorly understood. The objectives of this study were to evaluate adherence to a musculoskeletal infection (MSKI) diagnostic CP and identify recurrent failure points leading to missed diagnostic opportunities (MDOs).

METHODS

Retrospective chart review was performed from January 2018 to February 2022 for children 6 months to 18 years of age who had an unplanned admission for MSKI after being evaluated and discharged from the pediatric emergency department (PED) for related complaints within the previous 10 days. MDOs were identified using the Revised Safer Dx. Demographic and clinical characteristics of children with and without MDOs were compared using bivariate descriptive statistics. An improvement team reviewed the diagnostic trajectories of MDOs for deviations from the MSKI CP and developed a fishbone diagram to describe contributing factors to CP deviations.

RESULTS

The study identified 21 children with and 13 children without MSKI-associated MDOs. Children with MDOs were more likely to have an initial C-reactive protein value > 2 mg/dL (90.0% vs. 0%, p = 0.01) and returned to care earlier than children without MDOs (median 2.8 days vs. 6.7 days, p = 0.004). Factors contributing to MDOs included failure to obtain screening laboratory tests, misinterpretation of laboratory values, failure to obtain orthopedic consultation, and failure to obtain definitive imaging.

CONCLUSION

Several recurrent deviations from an MSKI diagnostic CP were found to be associated with MDOs. Future quality improvement efforts to improve adherence to this MSKI CP may prevent MDOs.

Virtual Reality vs. High-Fidelity Mannequin-Based Simulation: A Pilot Randomized Trial Evaluating Learner Performance

Background Virtual Reality (VR) simulation has been found to be useful in learning technical and non-technical skills. However, empirical data about its efficacy in clinical education are limited. This pilot study compares the efficacy of VR to mannequin-based simulation for learners managing status epilepticus (SE). Methods Pediatric and emergency medicine interns at an academic tertiary care referral center were randomized to either VR (intervention, using an Oculus Rift^Ⓡ (Occulus from Facebook, Facebook Inc., USA)) or mannequin-based (control) simulation for the same SE scenario. The control group participated in two mannequin-based simulation sessions while the intervention group had a VR session followed by a mannequin-based session. Sessions were one-one with an instructor and held three months apart. Performance was assessed by measuring the time-to-critical actions during the second session. Results Of 42 interns, 22 were in the intervention group and 20 in the control group. There was no statistical difference in time-to-critical actions for VR vs. standard groups; for example, VR times (in seconds) compared to standard times were 18.1 (SD 10.5) and 18.9 (SD 15.8) (p=.90) for oral suction, and 61.6 (SD 24.8) and 62.8 (SD 26.9) (p=.82) for IV lorazepam completion. Conclusion This pilot trial suggests that VR is feasible for clinical simulation. We did not find a significant difference between the two groups in learner performance. Larger studies are needed to corroborate our findings, investigate the best applications of VR in clinical training, and determine if it could lead to more rapid learning at a lower cost.
