OBJECTIVE An accurate computable representation of food and drug allergy is essential for safe healthcare. Our goal was to develop a high-performance, easily maintained algorithm to identify medication and food allergies and sensitivities from unstructured allergy entries in electronic health record (EHR) systems. MATERIALS AND METHODS An algorithm was(More)
OBJECTIVES To confirm the utility of a 10-point Surgical Apgar Score to rate surgical outcomes in a large cohort of patients. DESIGN Using electronic intraoperative records, we calculated Surgical Apgar Scores during a period of 2 years (July 1, 2003, through June 30, 2005). SETTING Major academic medical center. PATIENTS Systematic sample of 4119(More)
OBJECTIVE To determine whether use of intermediate acting neuromuscular blocking agents during general anesthesia increases the incidence of postoperative respiratory complications. DESIGN Prospective, propensity score matched cohort study. SETTING General teaching hospital in Boston, Massachusetts, United States, 2006-10. PARTICIPANTS 18,579 surgical(More)
BACKGROUND Deep brain stimulation (DBS) is a proven treatment for various movement disorders resistant to medical management. Complications such as postsurgical infection can negate benefits and increase patient morbidity. We sought to better define risk factors for infection. METHODS We performed a review of DBS cases at our institution from January 1996(More)
BACKGROUND The aim of this study is to investigate how the Charlson Comorbidity Index (CCI) scores contribute to increased length of stay (LOS) and healthcare costs in hip fracture patients. MATERIALS AND METHODS Through retrospective analysis at an Urban level I trauma center, charts for all patients over the age of 60 years who presented with low-energy(More)
Use of anesthesia and the cold environment of an operating room inhibits thermoregulation in a patient body causing perioperative hypothermia. In the worst case, this situation may cause death. Maintaining normothermia is thus a key requirement during the perioperative period. In today's state-of-the-art, normothermia is maintained through a number of(More)
The surgical Apgar score predicts major 30-day postoperative complications using data assessed at the end of surgery. We hypothesized that evaluating the surgical Apgar score continuously during surgery may identify patients at high risk for postoperative complications. We retrospectively identified general, vascular, and general oncology patients at(More)
BACKGROUND Operative fixation of ankle fractures is common. However, as reimbursement plans evolve with the potential for bundled payments, it is critical that orthopedic surgeons better understand factors influencing the postoperative length of stay (LOS) in patients undergoing these procedures to negotiate appropriate reimbursement. We sought to identify(More)
