The Cost of a Learner in the Pediatric Emergency Department: A Comparison Across Two Pediatric Emergency Departments.

Objectives: Experimental learning is a foundation of medical education, but a learner in the pediatric emergency department impacts utilization, time and disposition metrics. Our study sought to compare the effect of a resident learner on metrics between 2 pediatric emergency departments.

Methods: This retrospective study was conducted in 2019 in 2 pediatric emergency departments of tertiary care hospitals.

Total Hospital Costs and Readmission Rate of Patient-Specific Instrument in Total Knee Arthroplasty Patients.

Despite advancements in surgical technique and component design, implant loosening, stiffness, and instability remain leading causes of total knee arthroplasty (TKA) failure. Patient-specific instruments (PSI) aid in surgical precision and in implant positioning and ultimately reduce readmissions and revisions in TKA. The objective of the study was to evaluate total hospital cost and readmission rate at 30, 60, 90, and 365 days in PSI-guided TKA patients.
