Diversion of controlled substances in the perioperative setting is an ongoing challenge, with consequences for patients, anesthesiologists, perioperative staff, and health care facilities alike. Perioperative environments are at high risk for diversion, since controlled substances are frequently handled in these settings, with varying levels of oversight. In this narrative review, we summarize strategies for preventing diversion of controlled substances in perioperative settings (i.e., operating rooms, endoscopy suites, and postanesthesia recovery units). ⋯ Although awareness of perioperative controlled substance diversion has been improving, there are too few data to suggest an optimal approach. Anesthesia departments will need to work collaboratively with hospital pharmacies and actively select strategies that are reasonable given local resources.

Randomized Controlled Trial
A model to predict level of adherence to prehabilitation in older adults with frailty having cancer surgery.
Preoperative exercise could improve postoperative outcomes for people with frailty; however, little is known about how to predict older people's adherence to exercise before surgery (i.e., prehabilitation) programs. Our objective was to derive and validate a model to predict prehabilitation adherence in older adults living with frailty before cancer surgery. ⋯ A prespecified multivariable model may help to explain a modest degree of variation in prehabilitation adherence in older people with frailty. While this model is an important step toward personalizing prehabilitation support, this study was limited by a small sample size and future research is needed to better understand personalized prediction of prehabilitation adherence in older people with frailty.

Randomized Controlled Trial Observational Study
Accuracy of the Nova StatStrip® glucometer in patients undergoing major abdominal surgery: an observational study.
While the Nova StatStrip® Glucose Hospital Meter System (Nova Biomedical, Waltham, MA, USA) is approved for point-of-care testing (POCT) in critically ill patients, its use during major abdominal surgery has not been evaluated. The purpose of this study was to assess the accuracy of the Nova StatStrip glucometer in patients undergoing major hepatobiliary procedures using the Parkes error grid (ISO15197:2013) and criteria defined by the Clinical and Laboratory Standards Institute (CLSI) POCT12-A3 guideline. ⋯ ClinicalTrials.gov (NCT01528189); registered 7 February 2012.

The extent to which postoperative hypotension contributes to renal injury remains unclear, much less what the harm thresholds might be. We therefore tested the primary hypothesis that there is an absolute hypotensive arterial pressure threshold for acute kidney injury during the initial seven days after noncardiac surgery. ⋯ Postoperative hypotension, defined as the lowest postoperative mean arterial pressure < 80 mm Hg, was associated with acute kidney injury after noncardiac surgery. A prospective trial will be required to determine whether the observed association is causal and thus amenable to modification.

Patients undergoing lung resection are at increased risk for acute kidney injury (AKI) in the immediate postoperative period, with important consequences for longer term morbidity and mortality. Lung resection surgery has unique considerations that could increase the risk of AKI, including lung resection volume, duration of one-lung ventilation (OLV), and intraoperative fluid restriction. Yet, specific risk factor data are lacking. The objective of this study was to identify independent risk factors for early AKI after lung resection surgery. ⋯ Acute kidney injury occurs frequently after lung resection surgery and is associated with increased risk of postoperative complications. Increased duration of OLV may be a risk factor for AKI in this population.
