Diagnostic Reasoning of Resident Physicians in the Age of Clinical Pathways

Management Protocol for Uncomplicated Peritonsillar Abscess: Standardizing Care and Improving Emergency Medicine Resident Confidence

INTRODUCTION

A peritonsillar abscess (PTA) is a frequent reason for a visit to the emergency department. As there are no current published guidelines for medical versus surgical management, attending physicians vary among management tendencies, generating uncertainty among resident physicians. This project established a standard of care for managing patients with PTA and provided clear management guidelines to the emergency department, in collaboration with the otolaryngology department, at a community academic hospital.

METHODS

Pre- and post-interventional, anonymous surveys were given to assess resident physician confidence in the management of PTA. A proposed management protocol was developed based on existing literature and approved by both the emergency medicine (EM) and otolaryngology (ENT) departments. The protocol was then disseminated during in-person didactic sessions to EM residents and ENT residents for use over a four-month interventional period.

RESULTS

The mean confidence level for all residents increased significantly after the implementation of the protocol (p<0.001). The increase in confidence level for "antibiotic selection for PTA" (p=0.72) and "inpatient PTA management" (p=0.20) was not statistically significant for the post-graduate year (PGY) 3 and 4 residents. The increase in confidence level was higher overall for PGY 1 and 2 residents (95% CI 2.25 ± 1.09, p<0.001) than for PGY 3 and 4 residents (95% CI 1.73 ± 1.09, p=0.003).

CONCLUSION

The implementation of a standardized protocol for the management of PTA proved to be an effective tool in assisting residents and improving their confidence. This study highlights the importance of establishing guidelines in clinical practice to promote consistent and evidence-based management strategies for PTA. By providing clear guidelines, this protocol enhances communication among healthcare providers and contributes to the delivery of high-quality care to patients with PTA.

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.
