Preoperative geriatric consult or assessment
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.
