BACKGROUND The authors sought to identify the incidence, risk factors, and mortality impact of acute kidney injury (AKI) after general surgery using a large and representative national clinical data set. METHODS The 2005-2006 American College of Surgeons-National Surgical Quality Improvement Program participant use data file is a compilation of outcome(More)
A descriptive severity scoring system for injuries to the hand, distal to the carpus, has been designed. Each ray of the hand is assessed separately. Each ray's score is then multiplied by a weighting factor for that ray and added to the scores of the other rays to obtain a total score for the injury. This system has been tested on a series of specimen(More)
Biliary complications remain a significant problem following liver transplantation in the Model for End-Stage Liver Disease (MELD) era. We hypothesized that donor, recipient, and technical variables may differentially affect anastomotic biliary complications in MELD era liver transplants. We reviewed 256 deceased donor liver transplants after the(More)
OBJECTIVE To determine the utility of adding oral nonabsorbable antibiotics to the bowel prep prior to elective colon surgery. SUMMARY BACKGROUND DATA Bowel preparation prior to colectomy remains controversial. We hypothesized that mechanical bowel preparation with oral antibiotics (compared with without) was associated with lower rates of surgical site(More)
OBJECTIVE To assess the utility of full bowel preparation with oral nonabsorbable antibiotics in preventing infectious complications after elective colectomy. BACKGROUND Bowel preparation before elective colectomy remains controversial. We hypothesize that mechanical bowel preparation with nonabsorbable oral antibiotics is associated with a decreased rate(More)
BACKGROUND The authors sought to determine the incidence and risk factors for perioperative cardiac adverse events (CAEs) after noncardiac surgery using detailed preoperative and intraoperative hemodynamic data. METHODS The authors conducted a prospective observational study at a single university hospital from 2002 to 2006. All American College of(More)
Patient safety rounds (PSRs) were established at the University of Michigan Medical Center to improve patient safety by opening a new line of communication between the chief of staff and frontline caregivers. Patient safety rounds are biweekly, hour long meetings between the chief of staff and care givers on individual patient care units. In the past 4(More)
BACKGROUND The National Surgical Quality Improvement Project (NSQIP) has reduced morbidity rates in Veterans Affairs Hospitals. As the NSQIP methods move to private-sector hospitals, funding responsibilities will shift to the medical center. The objective of the current study was to calculate hospital costs associated with postoperative complications,(More)
BACKGROUND Liver transplantation for inherited metabolic disorders aims to save the patient's life when the disorder is expected to progress to organ failure, and to cure the underlying metabolic defect. METHODS We retrospectively analyzed 146 pediatric liver transplants (28 metabolic; 118 non-metabolic) performed between 1986 and 2000. RESULTS(More)
OBJECTIVES Validate a retrospective venous thromboembolism (VTE) risk scoring method, which was developed at the University of Michigan Health System and based on the Caprini risk assessment model, and assess the confounding effects of VTE prophylaxis. BACKGROUND Assessing patients for risk of VTE is essential to initiating appropriate prophylaxis and(More)
