Groups 2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code | Source |
|---|---|---|---|---|---|---|
| Group 1 | 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. | 103 | 7,352 | OG000 | ClinicalTrials.gov |
| Group 2 | 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 | 6,172 | 259,147 | OG001 | ClinicalTrials.gov |
