Randomized Controlled Trial Multicenter Study
Enhancement of surgical informed consent by addition of repeat back: a multicenter, randomized controlled clinical trial.
In this randomized, controlled, unblinded trial, we sought to test Repeat Back's (RB) effect on comprehension following informed consent discussions. ⋯ RB implemented within an electronic informed consent system improved patient comprehension. The additional time required was acceptable to providers. RB should be considered as an enhancement to surgical informed consent.This clinical trial was registered at http://www.clinicaltrials.gov (Identifier NCT00288899).

Randomized Controlled Trial Multicenter Study
Warming and humidification of insufflation carbon dioxide in laparoscopic colonic surgery: a double-blinded randomized controlled trial.
We aimed to test the hypothesis that warming and humidification of insufflation CO2 would lead to reduced postoperative pain and improved recovery by reducing peritoneal inflammation in laparoscopic colonic surgery. ⋯ Warming and humidification of insufflation CO2 does not attenuate the early inflammatory cytokine response, and confers no clinically significant benefit in laparoscopic colonic surgery.

Multicenter Study
Effect of a 19-item surgical safety checklist during urgent operations in a global patient population.
To assess whether implementation of a 19-item World Health Organization (WHO) Surgical Safety Checklist in urgent surgical cases would improve compliance with basic standards of care and reduce rates of deaths and complications. ⋯ Implementation of the checklist was associated with a greater than one-third reduction in complications among adult patients undergoing urgent noncardiac surgery in a diverse group of hospitals. Use of the WHO Surgical Safety Checklist in urgent operations is feasible and should be considered.

Randomized Controlled Trial Multicenter Study
Maximal sterile barrier precautions do not reduce catheter-related bloodstream infections in general surgery units: a multi-institutional randomized controlled trial.
To investigate whether maximal sterile barrier precautions (MSBPs) during central venous catheter (CVC) insertion are truly effective in preventing catheter-related bloodstream infections (CRBSIs) in patients in general surgical units. ⋯ This study is larger in sample size than the one performed by Raad et al and could not demonstrate better prevention of CRBSIs by MSBP compared with SSBP. A large randomized controlled trial or at least a meta-analysis of any other studies in the literature is necessary to reach to a conclusion on this issue.

Randomized Controlled Trial Multicenter Study Comparative Study
Morbidity and mortality of laparoscopic gastrectomy versus open gastrectomy for gastric cancer: an interim report--a phase III multicenter, prospective, randomized Trial (KLASS Trial).
The aim of this study was to evaluate the safety of this trial with respect to morbidity and mortality. ⋯ There was no significance difference in the morbidity and mortality between the 2 groups. Therefore, we conclude that this trial is safe and is thus ongoing.
