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.
