Predictive analysis of economic and clinical outcomes in total knee arthroplasty: Identifying high-risk patients for increased costs and length of stay.

Purpose: The purpose of this study was to predict high-risk patients who experience significant increases in hospital charges and length of stay (LOS) following specific postoperative complications.

Methods: This study analyzed over two million patients from the Nationwide Inpatient Sample database undergoing elective total knee arthroplasty (TKA) for primary osteoarthritis. Baseline demographics, clinical characteristics and incidence of postoperative complications were examined.

Nationwide community based emergency centers reveal scale of hand trauma.

Introduction: This study describes the characteristics of hand trauma treated in community-based emergency centers (CBECs) in Israel. It was hypothesized that the rate of hand trauma, as well as patient and injury characteristics, would differ from a recent study of patients treated in hospital emergency departments (EDs) in Jerusalem.

Methods: Data on all hand injury patients treated at any of the CBECs belonging to a large nationwide chain in 2017 were retrieved from the electronic medical records of the treatment centers, including demographic and clinical characteristics.
