Multicenter Study
Secondary overtriage: a consequence of an immature trauma system.
Trauma systems are designed to bring the injured patient to definitive care in the shortest practical time. This depends on prehospital destination criteria (primary triage) and interfacility transfer guidelines (secondary triage). Although primary undertriage is associated with increased costs and worse outcomes for selected injuries, secondary overtriage can overwhelm system resources and delay definitive care. The purpose of this study was to determine the incidence of secondary overtriage in a region without a formal trauma system. ⋯ A substantial proportion of transferred trauma patients require only brief diagnostic or observational care. Excessive overtriage calls for development of a regional inclusive trauma system with established primary and secondary triage guidelines to improve access to care and trauma system efficiency.

The protein kinase C (PKC) family consists of 12 isoforms, 6 of which have been found in human myocardium (PKC alpha, beta I/beta II, delta, epsilon, eta, and lambda/iota). These kinases function in regulation of contractility, ion channels, and in cellular protection or damage during ischemia-reperfusion injury. This study investigated the effects of controlled ischemia-reperfusion injury through cardioplegic arrest on PKC activity in patients undergoing cardiac surgery. ⋯ PKC delta and epsilon have previously been shown to mediate and protect, respectively, from ischemia-reperfusion injury after myocardial ischemia. Demonstration of increases in their activity after cardioplegic arrest provides support for their possible role in myocardial function after cardiac surgery. Isoform-specific modulators may be of potential therapeutic value in treating postoperative myocardial dysfunction.

Multicenter Study Comparative Study
Comparing outcomes after transthoracic and transhiatal esophagectomy: a 5-year prospective cohort of 17,395 patients.
Debate continues over whether transhiatal esophagectomy (THE) offers decreased morbidity and mortality compared with transthoracic esophagectomy (TTE). To definitively answer this question, we used the Nationwide Inpatient Sample database to compare morbidity and mortality after THE and TTE. ⋯ This large-volume, multicenter study constitutes the largest cohort in the literature to compare outcomes after THE and TTE. These findings indicate the outcomes after THE and TTE for esophageal disease are equivalent, although higher-volume centers will have lower morbidity and mortality.

There is great interest in efficiently evaluating health care quality, but there is controversy over the use of administrative versus clinical data methods. We sought to compare actual mortality with risk-adjusted expected mortality in a sample population calculated by two different methods; one based on preexisting administrative records and one based on chart reviews. ⋯ Risk-adjusted mortality estimates were comparable using administrative or clinical data. Minor performance differences might still have implications. Because of the potential lower cost of using administrative data, this type of algorithm can be an efficient alternative and should continue to be investigated.

Anastomotic leakage in colorectal surgery remains a major challenge because of its early and late consequences. ⋯ In right colectomy for cancer, preoperative nutritive support leading to regain of lost weight could reduce postoperative morbidity. Concerning left colectomy, if colonic cleanliness is poor, intraoperative colonic lavage should be done. When poor colonic cleanliness is associated with palliative resection and low distal rectal anastomosis, a protective stoma should be considered.
