About this study

The investigators will create a frailty index using health administrative data available for older people having surgery. The index will be based on the Canadian Study of Health and Aging Frailty Index and standard recommendations for creation of frailty indices.

Once derived the index will be tested to measure its association with outcomes, as well as its discrimination. Various representations of the frailty index will be tested (primary-as a continuous measure; secondary as a binary, categorical and fractional polynomial variable). Performance in subgroups will also be evaluated,

Treatment and study plan

Frailty index

Diagnostic Test

A frailty index composed of variables from health administrative data that cover multi-system health issues. Deficits will be coded as present or absent, and the number of deficits present will be divided by the total number of deficits present to provide an overall score between 0-1.

Primary outcomes

  1. Survival for One Year After Surgery

    Time frame: Date of surgery to 365 days after surgery

    Still being alive (no death date) in the registered persons database Outcome is binary, exposure is per 0.1 unit increase

Secondary outcomes

  1. Institutional Discharge

    Time frame: Date of surgery to date of hospital discharge, or up to one year after surgery (whichever comes first)

    Discharge to long term care or continuing care facility at the time of hospital discharge
