Objective: To evaluate the safety of omitting the conventional preoperative history and physical examination (H&P) for low-risk cataract surgery patients.
Design: Comparison of outcomes before and after the January 1, 2015 system wide implementation of a program that eliminated the conventional preoperative H&P for low-risk patients as identified by a 12-item risk stratification questionnaire.
Participants: Two separate groups of Winnipeg residents who had cataract surgery at the city's sole ophthalmological referral centre between July 1 and December 31, 2014 (preimplementation reference group) or between October 1, 2015 and March 31, 2016 (postimplementation intervention group).
Background: Cognitive impairment and deficits in functional performance are major concerns following surgery, particularly for older patients. The objective of this study was to examine predictors of postoperative cognitive and functional difficulties and explore the relationship between presurgery and postsurgery cognitive ability and functional performance.
Methods: 89 patients undergoing elective abdominal aortic aneurysm (AAA) surgery were administered a battery of cognitive measures preoperatively, at the time of discharge from hospital and 3 months postoperatively.
Background: Perioperative delirium is common in high-risk surgery and is associated with age, education, preoperative cognitive functioning, pre-existing medical conditions, and postoperative complications. We investigated these factors as well as lifestyle and demographic variables by using cognitive measures that were more sensitive than those used in previous studies.
Methods: Extensive medical and demographic data were collected on 102 patients between 41 and 88 years of age to identify comorbidities and lifestyle considerations preoperatively.
