Background Previous studies have demonstrated that obesity is paradoxically associated with a lower risk of mortality after noncardiac surgery. This study will determine the impact modified metabolic syndrome (defined as presence obesity, hypertension, and diabetes) on perioperative outcomes. Methods based data from 310,208 patients in American College Surgeons National Surgical Quality Improvement Program database. We estimated separate multivariate logistic regression models for 30-day...
In Brief Objective: To develop and validate a new ICD-9 injury model that uses regression modeling, as opposed to simple ratio measurement, estimate empiric severities for each of the injuries in ICD-9-CM lexicon. Background: The American College Surgeons now requires International Classification diseases ninth Edition (ICD-9-CM) codes coding National Trauma Databank. Injury Severity Score (ICISS) is best-known risk-adjustment when are recorded using coding, would likely be used risk-adjust...
Shared decision making in surgical care requires a culture shift. For patients at high risk for adverse events after surgery, or cases with an equivocal risk–benefit balance, evidence-based may require input from multidisciplinary group of experts.
Hospital readmissions are believed to be an indicator of suboptimal care and the focus efforts by Centers for Medicare Medicaid Services reduce health cost improve quality. Strategies surgical may most effective if applied prospectively patients who at increased risk readmission. Hospitals do not currently have means identify high unplanned rehospitalizations.To examine whether American College Surgeons National Surgical Quality Improvement Program (ACS NSQIP) predicted major complications...
Background There is strong evidence that pain undertreated in black and Hispanic patients. The association between race ethnicity the use of epidural analgesia for labor not well described.

This retrospective cohort study was based on 81,883 women admitted childbirth 1998 2003. Results...
In Brief Objective: To develop a statistically rigorous trauma mortality prediction model based on empiric estimates of severity for each injury in the abbreviated scale (AIS) and compare performance this new with score (ISS). Summary Background Data: Mortality rates at centers should only be compared after adjusting differences severity, but no reliable measure currently exists. The ISS has served as standard anatomic 30 years. However, it relies individual severities assigned by experts...
Complications during central venous catheterization (CVC) are not rare and can be serious. The use of ultrasound (US) CVC has been recommended to improve patient safety.

To examine whether failure-to-rescue is an important mechanism driving outcome differences across low- and high-mortality hospitals caring for trauma patients.Reducing medical errors complications has become the focus of quality improvement efforts. Patients undergoing general vascular surgery in have similar rates but higher compared to patients low-mortality hospitals.Retrospective cohort study based on 54,713 patient records National Trauma Databank 2007. Hospitals were classified as...
Performance benchmarking requires accurate measurement of injury severity. Despite its shortcomings, the Injury Severity Score (ISS) remains industry standard 40 years after creation. A new severity measure, Trauma Mortality Prediction Model (TMPM), uses either Abbreviated Scale (AIS) or DRG International Classification Diseases-9th Rev. (ICD-9) lexicons and may better quantify compared with ISS. We performance TMPM ISS other measures in a single cohort patients.We included 337,359 patient...
