Hepatic resection is associated with substantial morbidity and resource use. To contain costs and improve outcomes, recent health care regulations focus on reducing hospital readmissions while using readmission rates as a quality measure. The goal of this investigation was to characterize the incidence, patterns, and risk factors for readmission after resection for hepatocellular carcinoma. ⋯ Early readmission after hepatectomy remains relatively common. Postoperative complications and patient comorbidities are the dominant factors in readmission, and we must be mindful of those patients at increased risk for readmission.

Readmission after complex gastrointestinal surgery is a frequent occurrence that burdens the health care system and leads to increased cost. Recent studies have demonstrated 30- and 90-day readmission rates of 15% and 19%, respectively, following pancreaticoduodenectomy. Given the psychosocial issues often associated with chronic pancreatitis, we hypothesized that readmission rates following surgery for chronic pancreatitis would be higher than previously reported for pancreaticoduodenectomy. ⋯ To our knowledge, our data represent the first report demonstrating very high readmission rates after surgery for chronic pancreatitis, more than double the previous rates reported for pancreaticoduodenectomy. This cohort of patients requires extensive discharge planning focused on pain control, nutritional optimization, and close postoperative monitoring.

Hemorrhagic shock leads to a complex cascade of metabolic and hormonal processes that may result in hypoperfusion, end organ damage, and death even when blood pressure is restored. Studies have shown that morbidity and mortality could be attributable to a diminished availability of endothelial-derived nitric oxide (eNO). It is unclear whether adequate levels of citrulline (CIT) and arginine (ARG)--the precursors of eNO synthesis--are available to sustain the eNO needed to maintain adequate perfusion in severe shock. An indirect measure of eNO is the ratio between the levels of ARG and its inhibitor asymmetric dimethylarginine (ARG/ADMA). The purpose of the study was to identify the temporal impact of the ARG/ADMA ratio, ARG, CIT, and ADMA in response to hemorrhage and crystalloid fluid resuscitation by the use of a porcine model of severe hemorrhagic shock. ⋯ Our results suggest that a sufficient decrease in MAP during hemorrhagic shock is associated with a subsequent increase in IL-6, persisting impairment of end organ perfusion, and evidence of ongoing eNO deficit and an increase in ADMA despite resuscitation. The ARG/ADMA ratio reflects both of these parameters and corresponds to the increase in IL-6 and persistent ischemia after resuscitation. We propose that the mechanism of IL-6 increase in trauma derives from eNO deficiency, and the ARG/ADMA ratio more accurately depicts the pathologic mechanism responsible for increased morbidity and mortality in trauma.

Although hospital variation in costs and outcomes has been described for patients undergoing operation, the relationship between them is unknown. The purpose of this study was to evaluate this relationship among patients undergoing colon resection for cancer and identify characteristics of "high-quality, low-cost" hospitals. ⋯ Hospital costs are not correlated with outcomes in this population. More work is needed to identify means of providing high-quality care at lesser costs.

The goal of this study was to examine how industrial process improvement techniques could help streamline the preoperative workup. ⋯ Utilizing process improvement methodology, surgery patients can benefit from an improved, streamlined process with significant reduction in wait time from call to initial consult and initial consult to surgery, with reduced cancellations. This generalized process has resulted in increased practice throughput and efficiency and is applicable to any surgery practice.
