The investigators will use multilevel multivariable regression analysis to measure the association of sex with provision of guideline-based perioperative care for hip fracture surgery in Ontario.
In 2013, the Ontario Ministry of Health and Longterm Care published a 'Quality Based Procedures' guideline for care of hip fracture patients. The adjusted association of sex with receipt of 5 perioperative processes of care that can be accurately measured in health administrative data within this guideline will be investigated.
