Randomized Controlled Trial Multicenter Study
Anaesthetic depth and delirium after major surgery: a randomised clinical trial.
Postoperative delirium is a serious complication of surgery associated with prolonged hospitalisation, long-term cognitive decline, and mortality. This study aimed to determine whether targeting bispectral index (BIS) readings of 50 (light anaesthesia) was associated with a lower incidence of POD than targeting BIS readings of 35 (deep anaesthesia). ⋯ ACTRN12612000632897.

Randomized Controlled Trial
Effect of Hypotension Prediction Index-guided intraoperative haemodynamic care on depth and duration of postoperative hypotension: a sub-study of the Hypotension Prediction trial.
Intraoperative and postoperative hypotension are associated with morbidity and mortality. The Hypotension Prediction (HYPE) trial showed that the Hypotension Prediction Index (HPI) reduced the depth and duration of intraoperative hypotension (IOH), without excess use of intravenous fluid, vasopressor, and/or inotropic therapies. We hypothesised that intraoperative HPI-guided haemodynamic care would reduce the severity of postoperative hypotension in the PACU. ⋯ Intraoperative HPI-guided haemodynamic care did not reduce the TWA of postoperative hypotension.

Specialist training bodies continue to devise innovative methods of gathering information on trainee workplace performance to meet the requirements of competency-based medical education. We reviewed recent innovations in workplace-based assessment (WBA) tools to identify strengths, weaknesses, and trade-offs inherent in their design and use. ⋯ Our synthesis of the literature on innovative WBAs provides a framework for categorising tool characteristics across seven dimensions, systematically teasing apart the considerations in design and use of workplace assessments. It also draws attention to the trade-offs inherent in tool design and selection, and enables a more deliberate consideration of the tool characteristics most appropriate to the local context.

Review
Morbidity, mortality, and systems safety in non-operating room anaesthesia: a narrative review.
Non-operating room anaesthesia (NORA) describes anaesthesia delivered outside a traditional operating room (OR) setting. Non-operating room anaesthesia cases have increased significantly in the last 20 yr and are projected to account for half of all anaesthetics delivered in the next decade. In contrast to most other medication administration contexts, NORA is performed in high-volume fast-paced environments not optimised for anaesthesia care. ⋯ Despite relatively few attempts to quantify safety concerns, it was possible to find a range of systems safety concerns repeated across multiple studies, including insufficient lighting, noise, cramped workspace, and restricted access to patients. Old and unfamiliar equipment, lack of team familiarity, and limited preoperative evaluation are also commonly noted challenges. Applying a systems view of safety, it is possible to suggest a range of methods to improve NORA safety and performance.
