This study aims to describe primary hip fracture surgeries and to identify patient-related and perioperative risk factors affecting outcomes. It will utilize data from the Swedish Perioperative Registry (SPOR) and the Swedish National Patient Register to track epidemiological changes, treatment outcomes, and perioperative factors.

Hip fractures, a significant health concern among the elderly, necessitate hospitalization and surgical intervention, with high mortality and morbidity rates within the first year post-surgery. The study will retrospectively analyze records of approximately 90,000 patients over 18 who underwent hip fracture surgery between 2018 and 2022. Key factors such as age, sex, preoperative health status, and perioperative care methods will be evaluated to determine their impact on complications, reoperation rates, and survival.

This research could inform future clinical practices and policies, aiming to optimize the treatment and management of elderly patients with hip fractures.

Inclusion Criteria:

- Patients aged 18+ with hip fractures, identified through ICD code S72*, who underwent surgery during the study period.

Exclusion Criteria:

• Patients without a Swedish personal identification number, as this is necessary to link data across registers.

Patients aged 18 years and older who underwent hip fracture surgery and were recorded in SPOR from January 1, 2018, to December 31, 2022.
