We sought to identify demographic or care process variables associated with increased 30-day readmission within the total hip and knee arthroplasty patient population. Using this information, we generated a model to predict 30-day readmission risk following total hip and knee arthroplasty procedures. Longer index length of stay, discharge disposition to a(More)
BACKGROUND The International Knee Documentation Committee (IKDC) Subjective Knee Evaluation Form is a patient-reported outcome with adult (1998) and pediatric (2011) versions validated at different ages. Prior longitudinal studies of patients aged 13 to 17 years who tore their anterior cruciate ligament (ACL) have used the only available adult IKDC, whereas(More)
BACKGROUND Up to 55% of total joint arthroplasty costs come from post-acute care, with large variability dependent on a patient's discharge location. At our institution, we identified a group of surgeons using a preoperative discharge planning protocol emphasizing the merits of home discharge. We hypothesized that using the protocol would increase patients'(More)
The effects of normothermic machine perfusion (NMP) on the postreperfusion hemodynamics and extrahepatic biliary duct histology of donation after cardiac death (DCD) livers after transplantation have not been addressed thoroughly and represent the objective of this study. Ten livers (5 per group) with 60 minutes of warm ischemia were preserved via cold(More)
BACKGROUND The clinical benefit of chronic suppression with oral antibiotics as a salvage treatment for periprosthetic joint infection is unclear. The purpose of this study was to compare infection-free prosthetic survival rates between patients who received chronic oral antibiotics and those who did not following irrigation and debridement with(More)
BACKGROUND Among nurses, skill retention after an electrocardiography blended-learning course is unknown. OBJECTIVES To compare 3- and 8-week electrocardiography test scores, compare scores by nurse and work characteristics and self-assessed electrocardiographic competence, and compare 1-year work retention with 3- and 8-week scores and change in scores(More)
BACKGROUND Two versions of the International Knee Documentation Committee (IKDC) Subjective Knee Evaluation form currently exist: the original version (1999) and a recently modified pediatric-specific version (2011). Comparison of the pediatric IKDC with the adult version in the adult population may reveal that either version could be used longitudinally.(More)
BACKGROUND Recent studies suggest that there is little benefit to routine preoperative staging CT of the thorax in colorectal cancer. OBJECTIVE The current study hypothesized that staging CT of the thorax is not mandated in all patients with colorectal cancer. DESIGN This study was a tertiary-care center retrospective observational study. PATIENTS(More)
PURPOSE Breast magnetic resonance imaging (MRI) is accepted as a useful adjunct to screening mammography for women at high risk for breast cancer. Nevertheless, concerns about false-positive findings remain, and data about MRI harms and yields are limited. The aim of this study was to quantify harms and yields of breast MRI over time in a large series of(More)
BACKGROUND AND OBJECTIVES Treatment of gastroesophageal reflux disease (GERD) with hiatal hernia in obese patients has proven difficult, as studies demonstrate poor symptom control and high failure rates in this patient population. Recent data have shown that incorporating weight loss procedures into the treatment of reflux may improve overall outcomes. (More)
