Importance The human and financial costs of treating surgical site infections (SSIs) are increasing. The number of surgical procedures performed in the United States continues to rise, and surgical patients are initially seen with increasingly complex comorbidities. It is estimated that approximately half of SSIs are deemed preventable using evidence-based(More)
Matching for several nominal covariates with many levels has usually been thought to be difficult because these covariates combine to form an enormous number of interaction categories with few if any people in most such categories. Moreover, because nominal variables are not ordered, there is often no notion of a "close substitute" when an exact match is(More)
OBJECTIVE To study the medical and financial outcomes associated with surgery in elderly obese patients and to ask if obesity itself influences outcomes above and beyond the effects from comorbidities that are known to be associated with obesity. BACKGROUND Obesity is a surgical risk factor not present in Medicare's risk adjustment or payment algorithms,(More)
OBJECTIVE To investigate the association between obesity and perioperative acute kidney injury (AKI), controlling for preoperative kidney dysfunction. BACKGROUND More than 30% of patients older than 60 years are obese and, therefore, at risk for kidney disease. Postoperative AKI is a significant problem. METHODS We performed a matched case-control study(More)
BACKGROUND To improve access to breast reconstruction for mastectomy patients, the United States enacted the Women's Health and Cancer Rights Act in January of 1999. The objective of the current study was to evaluate the impact of this legislation on patients with different insurance plans. METHODS Women aged ≥18 years who underwent mastectomy for cancer(More)
The presence of lymph node (LN) metastases in papillary thyroid cancer (PTC) has limited prognostic utility for predicting disease-specific survival. Pathologic features of the LNs beyond their presence and location do not factor into the AJCC staging system. Most LN metastases are microscopic. The natural history of patients with PTC and clinically evident(More)
AIM The study aimed to evaluate the relationship between insurance status and the management and outcome of acute diverticulitis in a nationally representative sample. METHOD A retrospective cohort analysis of a nationally representative sample of 1 031 665 hospital discharges of patients admitted for acute diverticulitis in the 2006-2009 Nationwide(More)
Interhospital transfer (IHT) is associated with mortality in medical and mixed intensive care units (ICUs), but few studies have examined this relationship in a surgical ICU (SICU) setting. We hypothesized that IHT is associated with increased mortality in SICU patients relative to ICU patients admitted within the hospital. We reviewed SICU and transfer(More)
OBJECTIVE Medical school does not specifically prepare students for surgical internship. Preinternship courses are known to increase confidence in multiple key areas. We examined the immediate effect and durability of effect of a surgical pregraduation preparatory course or "boot camp" on provider confidence in technical and medical management skills. (More)
This paper presents a new method for optimal matching in observational studies based on mixed integer programming. Unlike widely used matching methods based on network algorithms, which attempt to achieve covariate balance by minimizing the total sum of distances between treated units and matched controls, this new method achieves covariate balance(More)
