Description and validation of the Postoperative Discharge Recovery State outcome: a patient-partnered population-based cohort study
Authors' conclusion
The Postoperative Discharge Recovery State is a 5-level ordinal outcome that can be applied at key time points after surgery to quantify the proportion of patients in patient-prioritised discharge locations.

- Adults ≥65 yr having major, elective, noncardiac, non-orthopaedic surgery, Ontario, Canada, 2012–2022
- Participants
- 84,422 adults
- Outcome
- Postoperative Discharge Recovery State (5-level ordinal outcome)
- Follow-up
- POD 90
Methodological detailspopulation-based, patient-partnered, linked routinely collected data, internal-external validation
- Population-based
- Patient-partnered
- Linked routinely collected data
- Internal-external validation
Main finding
As reported in the abstract
Postoperative Discharge Recovery State distribution
- Dead
- 2718; 3.2%
- Hospitalised
- 1696; 2.0%
- In long-term care
- 179; 0.2%
- In rehabilitation
- 593; 0.7%
- At home
- 79 236; 93.9%
Observational data: associations, not effects.
Further findings
Construct validity and reliability
- Directionally expected associations with baseline characteristics supported construct validity
- Consistency in associations over time supported reliability
Convergent and predictive validity (days alive and at home)
- Convergent validity, ρ
- 0.373
- Predictive validity: fewer days at home with worse recovery state
Prespecified ordinal logistic regression model performance
- C-statistic
- 0.700
- Poor calibration; inadequate accuracy to support clinical use
