Time-sensitive, critical surgical illnesses require care at specialized centers. Trauma systems facilitate patient transport to designated trauma centers, but formal systems for nontraumatic critical illness do not exist. We created the critical care resuscitation unit to expedite transfers of adult critically ill patients with time-sensitive conditions to a quaternary academic medical center, hypothesizing that this would decrease time to transfer, increase transfer volume, and improve outcomes. ⋯ The critical care resuscitation unit dramatically increased the volume of critically ill surgical patients. It decreased transfer times, increased volume, and, for those who required urgent operation, decreased time from initial referral to operating room. This benefit seems to be most marked in patients needing urgent operation. This might be a paradigm shift expediting the transfer of patients with time-sensitive critical illness to an appropriately resourced specialty center.

Colorectal surgical site infections (C-SSIs) are a major source of postoperative morbidity. Institutional C-SSI rates are modeled and scrutinized, and there is increasing movement in the direction of public reporting. External validation of C-SSI risk prediction models is lacking. Factors governing C-SSI occurrence are complicated and multifactorial. We hypothesized that existing C-SSI prediction models have limited ability to accurately predict C-SSI in independent data. ⋯ Published C-SSI risk prediction models do not accurately predict C-SSI in our independent institutional dataset. Application of externally developed prediction models to any individual practice must be validated or modified to account for institution and case-mix specific factors. This questions the validity of using externally or nationally developed models for "expected" outcomes and interhospital comparisons.

Laparoscopic appendectomy is typically associated with inpatient hospitalization averaging between 1 and 2 days. In July 2010, a prospective protocol for outpatient laparoscopic appendectomy was adopted at our institution. Patients were dismissed from the post-anesthesia recovery room or day surgery if they met certain predefined criteria. Patients admitted to a hospital room as either full admission or observation status were considered failures of outpatient management. ⋯ Outpatient laparoscopic appendectomy can be performed with a high rate of success, low morbidity, and low readmission rate. This protocol has withstood the test of time. Widespread adoption has the potential for substantial health care savings.

Observational Study
Provider Bias Impacts Tidal Volume Selection and Ventilator Days in Trauma Patients.
The ARDSnet (Acute Respiratory Distress Syndrome Clinical Network) study demonstrated that low tidal volume (Vt) reduces mortality from ARDS. It is unknown whether low Vt is beneficial in at-risk trauma patients. We hypothesized that Vt selection would be low in accordance with ARDSnet criteria and that subsequent outcomes would be improved. ⋯ Trauma patients receiving high Vt were shorter, had higher BMI, and were more likely to be female. The consequences included longer ICU stays and more ventilator days. Formal calculation of PBW and subsequent Vt is advocated.

Although it is a useful metric for preoperative risk stratification, frailty can be difficult to identify in patients before surgery. We sought to develop a preoperative frailty-risk model combining sarcopenia with clinical parameters to predict 1-year mortality using a cohort of patients undergoing gastrointestinal cancer surgery. ⋯ Sarcopenia was combined with clinical factors to generate a composite risk-score that can be used to identify frail patients at greatest risk for 1-year mortality after gastrointestinal cancer surgery.
