Randomized Controlled Trial Meta Analysis Comparative Study
Bisoprolol and fluvastatin for the reduction of perioperative cardiac mortality and myocardial infarction in intermediate-risk patients undergoing noncardiovascular surgery: a randomized controlled trial (DECREASE-IV).
This study evaluated the effectiveness and safety of beta-blockers and statins for the prevention of perioperative cardiovascular events in intermediate-risk patients undergoing noncardiovascular surgery. ⋯ Bisoprolol was associated with a significant reduction of 30-day cardiac death and nonfatal MI, while fluvastatin showed a trend for improved outcome.

Randomized Controlled Trial Comparative Study
Midline versus transverse incision in major abdominal surgery: a randomized, double-blind equivalence trial (POVATI: ISRCTN60734227).
There are 2 main types of access for patients requiring major open, elective abdominal surgery: the midline or the transverse approach. The aim of this study is to compare both approaches by focusing on postoperative pain, complications, and frequency of incisional hernias. ⋯ The decision about the incision should be driven by surgeon preference with respect to the patient's disease and anatomy.

To determine the in-hospital mortality rates for patients undergoing colorectal resection for malignant or benign conditions, and to identify risk factors for in-hospital death, particularly the relationships with surgeon and hospital volume. ⋯ This large, population-based study suggests that surgeons who perform high volumes of colorectal resections achieve lower in-hospital mortality rates than surgeons with low volumes, whereas the hospital volume does not influence mortality.

To develop and validate a new ICD-9 injury model that uses regression modeling, as opposed to a simple ratio measurement, to estimate empiric injury severities for each of the injuries in the ICD-9-CM lexicon. ⋯ Because TMPM-ICD9 uniformly out-performs ICISS and the SWI model, it should be used in preference to ICISS for risk-adjusting trauma outcomes when injuries are recorded using ICD9-CM codes.

To test the construct validity of the Observational Teamwork Assessment for Surgery (OTAS) tool. ⋯ OTAS exhibits adequate construct validity as assessed by consistency in the scoring by expert versus novices-ie, expert raters produce significantly more consistent scoring than novice raters. Further validation should assess the learning curve for novices in OTAS. Relationships between OTAS, measures of technical skill, and behavioral responses to surgical crises should also be quantified.
