Predictors of mortality for preterm infants with intraventricular hemorrhage: a population-based study.
This study examined the risk factors for mortality in preterm infants with intraventricular hemorrhage (IVH). An overall inpatient mortality occurred in 10% of the cohort of 7437 preterm infants born between 2005 and 2014. Mortality risk was independently associated with a variety of factors including male sex, Asian race, lower gestational age, higher IVH grade, gastrotomy, tracheostomy, and shunt infection.

High-risk colorectal surgery: what are the outcomes for geriatric patients?
This study examines the national burden and age-specific outcomes of previously defined high-risk colorectal procedures (HRCP) in geriatric patients using the 2014 National Inpatient Sample. The authors found that outcomes after HRCP are worse for older patients and for nonelective cases. They suggest that this information can inform preoperative counseling and targeted quality improvement projects.

Association of inferior vena cava filter placement for venous thromboembolic disease and a contraindication to anticoagulation with 30-day mortality.
Despite the absence of data from randomized clinical trials, professional societies recommend inferior vena cava (IVC) filters for patients with venous thromboembolic disease (VTE) and a contraindication to anticoagulation therapy. Prior observational studies of IVC filters have suggested a mortality benefit associated with IVC filter insertion but have often failed to adjust for immortal time bias. The purpose of this study was to determine the association of IVC filter placement with 30-day mortality after adjustment for immortal time bias.

Current state of empyema management.
The goal of this study was to examine current treatment practices and outcomes for inpatient treatment of empyema. A comprehensive, longitudinal data set from the New York State Inpatient Database, encompassing an entire state cohort of hospitalized patients, was used. The cohort included 4,095 patients who were undergoing intervention for primary empyema and were discharged 2009 to 2014 with chest tube, video-assisted thoracoscopic surgery (VATS) decortication and drainage, or open drainage and decortication. Patients were categorized into these three groups by definitive treatment during their initial hospitalization. The findings indicate that patients who were managed with chest tubes showed higher readmission and reintervention rates, suggesting that some of these patients may benefit from earlier definitive surgical intervention.

Population-based approaches to treatment and readmission after spinal cord injury.
Recent studies in surgical and non-surgical specialties have suggested that patients admitted on the weekend may have worse outcomes. It is unclear whether this extends to patients with spinal cord injury (SCI). This study was designed to evaluate factors for readmission after index hospitalization for spinal cord injury. The study’s results suggested that the weekend effect, described previously in other patient populations, may not play as important a role in patients with SCI.

The impact of hospital volume on racial differences in complications, readmissions, and emergency department visits following total joint arthroplasty.
This study evaluates the impact of hospital volume on racial differences in outcomes following joint replacement. The study authors concluded that adjusting for hospital volume does not alter the risk of readmissions and ED use associated with minority race/ethnicity, suggesting that hospital volume alone may be insufficient to explain racial differences in outcome.

Trends in tracheostomy for mechanically ventilated patients in the United States, 1993-2012.
This study investigated trends in tracheostomy use, timing, and outcomes in the United States. It found that over the past two decades, tracheostomy use rose substantially in the United States until 2008, when use began to decline. In addition, there was an observed dramatic increase in discharge of tracheostomy patients to long-term care facilities.

Complications and resource use associated with surgery for Chiari Malformation type 1 in adults: a population perspective.
This study examined the complications and resource use associated with adult CM-1 surgery using administrative data. It concluded that complications after CM-1 surgery are common, and surgical complications are more frequent than medical complications. Also, certain comorbidities and demographic characteristics are associated with increased risk for complications.

Delayed-onset cytomegalovirus disease coded during hospital readmission in a multicenter, retrospective cohort of liver transplant recipients.
The researchers sought to determine the risk factors and outcomes of delayed-onset CMV disease among a representative cohort of liver transplant recipients from multiple centers. They found that delayed-onset CMV disease coded during hospital readmission occurred more commonly than early-onset CMV disease and that prior transplant failure or rejection was a risk factor for delayed-onset CMV disease.

Nationwide comparative impact of thoracic endovascular aortic repair of acute uncomplicated type B aortic dissections.
The objective of this study was to evaluate the impact of thoracic endovascular aortic repair (TEVAR) on mortality, morbidity, length of stay (LOS), and discharge status on patients with acute uncomplicated Type B aortic dissections (TBAD). It found that TEVAR for acute uncomplicated TBAD was associated with similar in-hospital mortality and renal failure as compared to medical management.
