Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Preoperative geriatric consult or assessment

Patients who have a geriatric assessment of consult billed in the 4 months before surgery

Preoperative geriatric consult or assessment

Intervention Type PROCEDURE

A preoperative geriatric consult or assessment will be considered to be present if such a consult or assessment is billed by a geriatrician for a patient in the cohort within 4 months preceding surgery. For the primary analysis we will collapse both geriatric consultations and comprehensive geriatric assessments into a single exposure level.

No Preoperative geriatric consult or assessment

Patients who do not have a geriatric assessment of consult billed in the 4 months before surgery

No Preoperative geriatric consult or assessment

Intervention Type PROCEDURE

No assessment or consult billed in the 4 months before surgery
