The impact of preoperative stroke on 1-year mortality and days at home alive after major surgery: an observational cohort study.

Objective: The lifetime risk of stroke is one in four people. As the population aged over 60 constantly expands, the impact of stroke on perioperative care is of increasing concern. This study investigates the effect of preoperative stroke on short- and long-term outcomes, hypothesizing that it decreases both 1-year mortality and days alive and at home up to 30 days after surgery (DAH30).

Days at home alive after major surgery in patients with and without diabetes: an observational cohort study.

Objective: We hypothesized that days at home alive up to 30 days after surgery (DAH30), a novel patient-centered outcome metric, as well as long-term mortality, would be impaired in patients with type 1 or 2 diabetes mellitus (DM) undergoing major surgery.

Methods: This cohort study investigated patients > 18 years with and without DM presenting for major non-cardiovascular, non-ambulatory surgical procedures at 23 hospitals in Sweden between 2007 and 2014. We identified 290,306 patients.

Risk factors for new antidepressant use after surgery in Sweden: a nationwide, observational cohort study.

Background: Whilst somatic complications after major surgery are being increasingly investigated, the research field has scarce data on psychiatric outcomes such as postoperative depression. This study evaluates the impact of patient and surgical factors on the risk of depression after surgery using the proxy measure of prescribed and collected antidepressants.

Methods: An observational, registry-based, national multicentre cohort study of individuals ≥18 yr of age who underwent noncardiac surgery between 2007 and 2014.
