Measure	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: 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: No assessment or consult billed in the 4 months before surgery
