Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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,

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Elective noncardiac surgery
Individuals having major noncardiac surgery following an elective hospital admission
Frailty index
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.
Emergency general surgery
Individuals having general surgery following an urgent hospital admission
Frailty index
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.
