In this report, we describe a novel training model that simulates the life-threatening injuries that confront trauma surgeons. An alternative to living laboratory animals, this inexpensive and readily available model offers good educational value for the acquisition and refinement of surgical skills that are specific to trauma surgery.
INTRODUCTION: To evaluate the impact of high body mass index (BMI) on perioperative outcomes following hysterectomies reported to the National Surgical Quality Improvement Program (NSQIP). METHODS: Retrospective analysis of NSQIP database Participant Use Data File (PUF) from 2012 to 2016. Patient characteristics and perioperative complications were evaluated across BMI groups, combining normal and overweight (N/O) group, and utilizing standard definitions for class I, II and III obesity. ICD 9/10 and CPT codes were utilized. Patients were stratified into four groups based on benign vs. malignant diagnosis, and open vs. minimally invasive (MIS) procedure. Exclusion criteria were invalid CPT codes, BMI < 18, or missing data. Cochran-Armitage trend tests were used to examine linear trends in rates across increasing BMI category. RESULTS: Of 202,929 hysterectomies, 173,669 (85.6%) were eligible for analysis. Increases in obesity over time were noted with 50.5% classified as obese in 2016 vs. 46.5% in 2012 (p<0.001). For all procedures, as BMI category increased the rate of wound complication increased. In benign disease, overall complication rates also increased with BMI (MIS: 7.7% in normal BMI to 9.31% in class III, Open: 14% to 22.4%; p < 0.001). In open procedures, wound, sepsis, and readmission rates increased for obese patients, regardless of diagnosis (p < 0.001). CONCLUSION: Hysterectomy procedures for obese women were associated with increased perioperative complications. Obese patients had higher rates of wound complications regardless of surgical approach or diagnosis, and had higher rates of sepsis and readmission in open procedures regardless of diagnosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
