The independent effect of cancer on outcomes: a potential limitation of surgical risk prediction.
This study aims to compare the use of common risk models for benign versus malignant gastrointestinal disease. It found that the National Surgical Quality Improvement Program (NSQIP) prediction models less effectively evaluate the risk of death in cancer patients as compared to patients with benign disease. A diagnosis of cancer is independently associated with an increased risk of surgical complications.

Postoperative hemorrhage and hospital revisit after transoral robotic surgery.
The researchers investigated the incidence and complications related to postoperative hemorrhage (POH) after transoral robotic surgery (TORS). Using HCUP data, they found that the incidence of POH after TORS was low, and few of these patients had a severe complication related to this event. Medical comorbidity and tonsillar subsite may be independent risk factors for POH.

Electronically available comorbidities should be used in surgical site infection risk adjustment.
A multicenter retrospective cohort study of patients undergoing surgical procedures at 28 US hospitals was performed. The authors developed a well-performing risk adjustment model for surgical site infections (SSI) using electronically available comorbidities. Healthcare-associated infections, such as SSIs, are used by the Centers for Medicare and Medicaid Services (CMS) as pay-for-performance metrics. The authors recommended that comorbidity-based risk adjustment should be strongly considered by the Centers for Disease Control and Prevention and CMS to adequately compare SSI rates across hospitals.

Prevalence and predictors of postdischarge antibiotic use following mastectomy.
This study determined utilization, predictors, and outcomes of postdischarge prophylactic antibiotics after mastectomy with or without immediate breast reconstruction. The study conclude that prophylactic postdischarge antibiotics are commonly prescribed after mastectomy; immediate reconstruction is the strongest predictor. The authors recommended stewardship efforts in this population to limit continuation of prophylactic antibiotics after discharge are needed to limit antimicrobial resistance.

Safety and perioperative adverse events in pediatric endoscopic sinus surgery: an ACS-NSQIP-P analysis.
This study describes safety outcomes of pediatric endoscopic sinus surgery (ESS) to identify risk factors for 30-day postoperative adverse events using the National Surgical Quality Improvement Program-Pediatric (NSQIP-P) database. It concluded that urgent/emergent procedures carry the greatest risk of postoperative adverse events, and black children are significantly more likely to undergo higher acuity surgery than white children.

A kidney graft survival calculator that accounts for mismatches in age, sex, HLA, and body size.
Models were adjusted for year of transplant and donor and recipient characteristics, with particular attention to mismatches in age, sex, human leukocyte antigens (HLA), body size, and weight. These models were used to create a calculator of estimated graft survival for living donors. This calculator provides useful information to donors, candidates, and physicians of estimated outcomes and potentially in allowing candidates to choose among several living donors.

Population-based assessment of complications following surgery for thyroid cancer.
The researchers sought to determine thyroid cancer surgery complication rates and identify at-risk populations by using the Surveillance, Epidemiology, and End Results-Medicare database. They concluded that the rates of thyroid cancer surgery complications are higher than predicted, and patients with older age, more comorbidities, and advanced disease are at greatest risk.

A decision model to estimate a risk threshold for venous thromboembolism prophylaxis in hospitalized medical patients.
To determine a threshold for prophylaxis based on risk of venous thromboembolism, the researchers constructed a decision model with a decision-tree following patients for 3 months after hospitalization, and a lifetime Markov model with 3-month cycles. They found that the prophylaxis threshold was relatively insensitive to low-molecular-weight heparin cost and bleeding risk, but very sensitive to patient age and life expectancy.

Evaluating organizational factors associated with postoperative bariatric surgery readmissions.
This study evaluated the association between readmissions and several organizational factors, including compliance with best practices to reduce unplanned hospital visits, major complication rates, and the emergency department-sourced readmission rate. It concluded that bariatric centers with higher rates of major complications and sites with emergency departments that are less likely to treat and discharge patients are more likely to have higher readmission rates.

Estimating the risks of breast cancer radiotherapy: evidence from modern radiation doses to the lungs and heart and from previous randomized trials.
The researchers estimated the absolute long-term risks of modern breast cancer radiotherapy. They concluded that, for long-term smokers, the absolute risks of modern radiotherapy may outweigh the benefits, yet for most nonsmokers (and ex-smokers), the benefits of radiotherapy far outweigh the risks. Hence, smoking can determine the net effect of radiotherapy on mortality, but smoking cessation substantially reduces radiotherapy risk.

30-day hospital readmission following otolaryngology surgery: analysis of a state inpatient database.
Researchers sought to determine patient and hospital-level risk factors associated with 30-day readmission for patients undergoing inpatient otolaryngologic surgery. Approximately one out of 12 patients undergoing otolaryngologic surgery had a 30-day readmission. Readmissions occur across a variety of types of procedures and hospitals. Most of the variability was driven by patient-specific factors, not structural hospital characteristics.

Impact of body mass index and genetics on warfarin major bleeding outcomes in a community setting.
The researchers conducted a case-control study to evaluate the association between body mass index and major bleeding risk among patients receiving warfarin. They found that obese patients had significantly lower major bleeding risk relative to non-obese patients . An exploratory analysis indicated a statistically significant interaction between CYP4F2*3 genetic status and obesity.
