About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • >65
  • Resident of Ontario
  • Having elective non-cardiac surgery (inpatient admission)

Exclusion criteria

  • Residing in a nursing home or long term care facility at baseline

Treatment and study plan

Preoperative geriatric consult or assessment

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

Procedure

No assessment or consult billed in the 4 months before surgery

Primary outcomes

  1. Number of Participants With All-Cause Mortality at 90-days

    Time frame: date of surgery to 90 days after surgery

    Death from any cause in the 90 days after surgery

Secondary outcomes

  1. Patient Safety Event

    Time frame: From surgery to hospital discharge (on average 6 to 7 days)

    Any Type 2 diagnostic code for a patient-safety event

  2. Hospital Length of Stay

    Time frame: date of surgery to date of hospital discharge, or 365 days after surgery, whichever comes first

  3. Non-independent Discharge Location

    Time frame: date of surgery to date of hospital discharge, or 365 days after surgery, whichever comes first

    Discharge disposition from hospital record that is not a home discharge without support

  4. 30-day Hospital Readmission

    Time frame: Date of discharge (on average 6 to 7 days) to 30 days after discharge (on average 5 weeks)

    New acute care hospitalization within 30-days of discharge from the index hospitalization
