Variations in Anesthesia Care for Hip Fracture Surgery

Sources of Variation in Anesthesia Care for Hip Fracture Surgery and the Association With Outcomes

The investigators will use health administrative data to examine the variation of anesthesia type for hip fracture surgery, as well as sources of variation and predictors of variation.

To evaluate the sources of variance in utilization of neuraxial anesthesia the investigators will use multilevel multivariable modeling strategies. This will allow identification of sources of variation (hospital, vs physician, vs patient characteristics), as well as identification of independent predictors of neuraxial use at each of these three levels.

The investigators will also evaluate the independent association of hospital level variation in neuraxial use on our outcomes of interest using multilevel multivariable regression.

Inclusion Criteria:

• Had hip fracture surgery
• Admitted to hospital on a non-elective basis

Exclusion Criteria:

• Do not hold a valid provincial health insurance account
