The Impact of Perioperative Geriatric Care on Outcomes After Elective Noncardiac Surgery

Completed

• Conditions: Aged; Epidemiology; Mortality; SURGICAL PROCEDURES, OPERATIVE
• Interventions: Procedure: Preoperative geriatric consult or assessment; Procedure: No Preoperative geriatric consult or assessment

• Registration Number: NCT02975375
• Lead Sponsor: Ottawa Hospital Research Institute

Brief Summary

The investigators will conduct a population-based study using health administrative data to evaluate the impact of preoperative geriatric consultation on postoperative outcomes in older patients having elective, non-cardiac surgery

Detailed Description

The investigators will use multilevel multivariable analyses to measure the association between preoperative geriatric assessment or consultation and outcomes after major elective non-cardiac surgery. Sensitivity analyses will be done to evaluate types and timing of geriatric care around surgery, as well as for effect modification based on patient and procedural factors.
