Objective:
To develop and validate a preoperative frailty index (pFI) for use in population-based health administrative (HA) data.
Summary Background Data:
Frailty is a robust predictor of adverse postoperative outcomes. Population-level frailty measures used in surgical studies have significant methodological limitations. Frailty indices (FIs) are a well-defined approach to measuring frailty with well-described methods for development and evaluation. An appropriate preoperative FI in HA data has not been derived or evaluated.
Methods:
Retrospective cohort study using linked HA data in Canada. We identified people> 65 years (2002–2015) who had major elective or emergency surgery. Standardized methods were used to construct a 30-variable pFI. Unadjusted and multilevel, multivariable adjusted models were used to measure the association of the pFI with 1-year mortality and institutional discharge. Elective …
