Association of preoperative anaesthesia consultation prior to elective noncardiac surgery with patient and health system outcomes: a population-based study.

Background: Surgical volumes and use of preoperative anaesthesia consultations are increasing. However, contemporary data estimating the association between preoperative anaesthesia consultation and patient (days alive and at home [DAH], mortality) and system (costs, length of stay, and readmissions) outcomes are not available.

Methods: We conducted a population-based comparative effectiveness study using linked health administrative data among patients aged ≥40 yr who underwent intermediate-risk to high-risk elective, inpatient, noncardiac surgery in Ontario, Canada (2009-17).

A systematic review of perioperative clinical practice guidelines for care of older adults living with frailty.

Background: Perioperative frailty is prevalent and requires complex management, which could be guided by clinical practice guidelines (CPGs). The objective of this systematic review was to identify and synthesise CPGs that provide perioperative recommendations specific to older adults living with frailty.

Methods: After protocol registration, we performed a systematic review of CPGs.
