Tracheostomy risk factors and outcomes after severe traumatic brain injury.
The researchers sought to determine risk factors associated with tracheostomy placement after severe traumatic brain injury (TBI) and subsequent outcomes among those who did and did not receive a tracheostomy. They concluded that age and insurance status are independently associated with tracheostomy placement, but not with mortality after severe TBI. Tracheostomy placement is associated with increased survival after severe TBI.

Switching generic antiepileptic drug manufacturer not linked to seizures: a case-crossover study.
The researchers estimated the risk of seizure-related events associated with refilling antiepileptic drugs (AED) with generic AEDs and the effect of switching between different manufacturers of the same generic drug. They found that among patients on a generic AED, refilling the same AED was associated with an elevated risk of seizure-related event; however, there was no additional risk from switching during that refill to a different manufacturer.

Postoperative 30-day readmission: time to focus on what happens outside the hospital.
The authors of this study aimed to understand the relative contribution of preoperative patient factors, operative characteristics, and postoperative hospital course on 30-day postoperative readmissions. They found that although postoperative readmissions are difficult to predict at the time of discharge, preoperative factors are the most important.

Use of hematopoietic growth factors and risk of thromboembolic and pulmonary toxicities in elderly patients with advanced ovarian cancer.
This study evaluated the risk of thromboembolic and pulmonary toxicities associated with hematopoietic growth factor (HGF) use (i.e., erythropoietin-stimulating agent [ESA] and/or colony-stimulating factor [CSF]) in a community-dwelling cohort of elderly patients with advanced ovarian cancer. An increased risk of thromboembolic events was observed in elderly patients with ovarian cancer who received ESA + CSF.

Variation in 60-day readmission for surgical-site infections (SSIs) and reoperation following spinal fusion operations for neuromuscular scoliosis.
The purpose of this study was to examine variation in hospital performance based on risk-standardized 60-day readmission rates for surgical-site infection (SSIs) and reoperation across 39 US Children's Hospitals. It found that reoperations were associated with an SSI in 70 percent of cases. Across hospitals, SSI and reoperation rates ranged from 1 percent to 11 percent and 1 percent to 12 percent, respectively.

Rethinking elective colectomy for diverticulitis: a strategic approach to population health.
The authors argue that a rethinking of elective colectomy should come from a patient-centered approach that considers the risks of recurrence, quality of life, patient wishes and experiences about surgical and medical treatment options as well as operative morbidity and risks.

Colonoscopy and risk of infective endocarditis in the elderly.
The authors estimated the risk of infective endocarditis (IE) after colonoscopy in individuals aged 70 to 79 without a history of colorectal cancer (CRC), endocarditis, or colectomy from a random 20% sample of Medicare beneficiaries. Their findings suggest that individuals without risk factors for IE and those without gastrointestinal symptoms did not have an elevated IE risk after colonoscopy. However, they found a modestly increased risk among individuals with risk factors for IE who undergo a polypectomy or a biopsy during a colonoscopy following recent symptoms.

Epidemiology of surgical site infection in a community hospital network.
The researchers described the epidemiology of complex surgical site infection (SSI) following commonly performed surgical procedures in community hospitals and to characterize trends of SSI prevalence rates over time for MRSA and other common pathogens. They found that the prevalence of MRSA SSI decreased from 2008 to 2012. This decrease in MRSA SSI prevalence led to an overall decrease in SSI prevalence.

Failure mode and effects analysis: a comparison of two common risk prioritisation methods.
The investigators compared a simplified scoring method with the traditional scoring method to determine the degree of congruence in identifying high-risk failures. They found that the simplified method did not result in the same degree of discrimination in the ranking of failures offered by the traditional method.

Laparoscopy decreases complications for obese patients undergoing elective rectal surgery.
This paper's goal was to determine whether obese patients undergoing laparoscopic rectal surgery experienced the same benefits as non-obese patients. The researchers found that laparoscopic rectal surgery is associated with fewer complications when compared to open rectal surgery in both obese and non-obese patients, and that obesity was an independent risk factor for postoperative complications.

Risks associated with anesthesia services during colonoscopy.
The researchers aimed to quantify the difference in complications from colonoscopy with vs without anesthesia services. They concluded that the overall risk of complications after colonoscopy increases when individuals receive anesthesia services. The widespread adoption of anesthesia services with colonoscopy should be considered within the context of all potential risks.

Comparative effect of contrast media type on the incidence of contrast-induced nephropathy: a systematic review and meta-analysis.
This review compared contrast-induced nephropathy (CIN) risk for contrast media within and between osmolality classes in patients receiving diagnostic or therapeutic imaging procedures. No differences were found in CIN risk among types of low-osmolar contrast media (LOCM). Iodixanol had a slightly lower risk for CIN than LOCM, but the lower risk did not exceed a criterion for clinical importance.

Nadir hematocrit on bypass and rates of acute kidney injury: does sex matter?
Recent literature has suggested that women, although more often exposed to lower nadir hematocrit (Hct), have a lower risk of postoperative renal dysfunction. The researchers assessed whether this relationship held across a large multicenter registry. They found that lower nadir Hct was associated with an increased risk of AKI, and the effect appears to be stronger among men than women.
