Impact of accountable care organizations on acute cholecystitis outcomes in the Rio Grande Valley.

Background: Accountable care organizations through the Affordable Care Act are to improve Medicare beneficiaries' health while reducing costs. We hypothesize that this model may shift care, disease burden, and costs to nonaffiliated hospital facilities in patients with acute cholecystitis.

Methods: A retrospective difference-in-differences analysis was performed to compare severity, postoperative complications, diagnostic modality, length of stay, and costs in patients with acute cholecystitis from a post-accountable care organization implementation period (January 2014 through December 2015) to a pre-accountable care organization period (January 2011 through December 2012).

Sleeve gastrectomy and Roux En Y gastric bypass: current state of metabolic surgery.

Purpose Of Review: Roux En Y gastric bypass (RYGB) is considered the bariatric gold standard. Recently, sleeve gastrectomy has gained significant popularity. Early evidence suggests sleeve gastrectomy as a well tolerated and efficacious alternative to RYGB.

Impact of a blood conservation program on 30-day morbidity and mortality: a cohort study.

Background: There are little published data on outcomes of blood conservation (BC) patients after noncardiac surgery. The objective of this study was to compare the surgical outcomes of patients enrolled in our BC program with that of the general population of surgical patients.

Methods: BC patients at our institution undergoing various surgical procedures were identified from the 2007-2009 National Surgical Quality Improvement Program database and compared with a cohort of conventional care (CC) patients matched by age, gender, and surgical procedure.

Preoperative anemia is an independent predictor of postoperative mortality and adverse cardiac events in elderly patients undergoing elective vascular operations.

Objective: The objective of this study was to assess the impact of preoperative anemia (hematocrit <39%) on postoperative 30-day mortality and adverse cardiac events in patients 65 years or older undergoing elective vascular procedures.

Background: Preoperative anemia is associated with adverse outcomes after cardiac surgery, but its association with postoperative outcomes after open and endovascular procedures is not well established. Elderly patients have a decreased tolerance to anemia and are at high risk for complications after vascular procedures.

FAST scan: is it worth doing in hemodynamically stable blunt trauma patients?

Background: During the last decade, focused assessment with sonography for trauma increasingly has become the initial diagnostic modality of choice in trauma patients. It is still questionable, however, whether its use results in the underdiagnosis of intra-abdominal injury. It also remains doubtful whether a positive focused assessment with sonography for trauma affects clinical decision making in hemodynamically stable blunt trauma patients as evidenced through abdominal computerized tomography use.
