Abstract:
A recent article in the New England Journal of Medicine describes the evolving reimbursement changes mandated by Medicare as a “coming battle” between primary care physicians and specialists.1 There has been very little to date in the critical care literature about these changes or how they might affect intensivists. In this article, we provide an overview of the legislative changes to Medicare, how they may affect physician reimbursement, and specifically how they might affect intensivists. It will be up to the critical care community to determine appropriate responses to this changing environment.

Abstract:
In a retrospective, single-center cohort of 50,314 adult surgical patients, we used readily available preoperative clinical data to model the number of major postoperative complications from none to ≥3. We included acute kidney injury; prolonged stay (>48 hours) in an intensive care unit; need for prolonged (>48 hours) mechanical ventilation; severe sepsis; and cardiovascular, wound, and neurologic complications.

Abstract:
We evaluated the performance of logistic regression, generalized additive models, naïve Bayes and support vector machines for forecasting postoperative sepsis and acute kidney injury. We assessed the impact of feature reduction techniques on predictive performance. Model performance was determined using the area under the receiver operating characteristic curve, accuracy, and positive predicted value.

Abstract:
We studied a single-center retrospective cohort of SAH patients hospitalized between 2000 and 2010 with follow-up until 2013. We classified patients who had an echocardiogram for clinically indicated reasons according to the predominate location of RLVD as classic SCM-apical form and variant SCM-basal form.


Abstract:
Acute kidney injury (AKI) is a serious complication, commonly occurring in the critically ill population, with devastating short- and long-term consequences. Despite standardization of the definition and staging of AKI, early recognition remains challenging given that serum creatinine level is a marker, albeit imperfect, of kidney function and not kidney injury.


Abstract:
On this background, a working group of the 15(th) Acute Dialysis Quality Initiative (ADQI) conference applied the consensus-building process informed by review of English language articles identified through PubMed search to address questions related to the opportunities, methodological requirements.


Abstract:
In a single-center cohort of 51,457 adult surgical patients undergoing major inpatient surgery, long-term cardiovascular-specific mortality was modeled using a multivariable subdistributional hazards model while treating any other cause of death as a competing risk and accounting for the progression to end-stage renal disease (ESRD) after discharge. Pre-existing CKD and ESRD, and postoperative AKI were the main independent predictors.

Abstract:
A single-center cohort of 3646 patients underwent inpatient vascular surgery from January 1, 2000, to November 30, 2010, at a tertiary care teaching hospital. To determine cause-specific mortality for patients undergoing vascular surgery, a proportional subdistribution hazards regression analysis was used to model long-term cardiovascular-specific mortality while treating any other cause of death as a competing risk.

Abstract:
We enrolled adult surgical patients at risk for AKI who were admitted to one of 39 intensive care units across Europe and North America. The primary end point was moderate-severe AKI (equivalent to KDIGO [Kidney Disease Improving Global Outcomes] stages 2-3) within 12 hours of enrollment.



Abstract:
Neurogenic stunned myocardium is a significant complication of subarachnoid hemorrhage. Diagnosis of neurogenic stunned myocardium is complicated by variable presentation. We present a case of a 23-year-old woman admitted with a subarachnoid hemorrhage from an arteriovenous malformation and associated aneurysm. Postoperatively, she developed pulmonary edema and mildly elevated cardiac biomarkers.


Abstract:
Perioperative acute kidney injury (AKI) is a common, morbid, and costly surgical complication. Current efforts to understand and manage AKI in surgical patients focus on prevention, mitigation of further injury when AKI has occurred, treatment of associated conditions, and facilitation of renal recovery. Lesser severity AKI is now understood to be much more common, and more morbid, than was previously thought.


Abstract:
Postoperative acute kidney injury (AKI) is not only one of the most common postoperative complications but is also associated with increased in-hospital mortality, decreased survival for up to 10 years after surgery and an increased risk for progression to chronic kidney disease and hemodialysis.


Abstract:
The elderly are particularly susceptible to trauma, and their outcomes are frequently dismal. Such patients often have complicated clinical courses and ultimately die of infection and sepsis. Recent research has revealed that although elderly subjects have increased baseline inflammation as compared with their younger counterparts.
