Missing the first post-operative visit is an independent risk factor for 90-day complication and re-admission following hip fracture surgery.

Abstract

Knowing the risk factors for poor outcomes following hip fracture surgery is necessary for appropriate patient care. The objective of this study was to determine if the first post-operative visit (POV) following hip fracture surgery is a risk factor for increased mortality, complications, and re-admissions. This was a retrospective review of 285 patients who underwent operative fixation of a hip fracture at an academic acute care hospital. Outcome measurements were 90-day and one year mortality, 90-day complications, and 90-day re-admission rates in patients who missed or attended their first post-operative visit following hip fracture surgery. 279 patients met inclusion criteria and had sufficient data for analysis, of which 213 (76.3%) made their first post-operative visit. 90-day and one-year mortality were significantly higher in the patients who missed their first POV (31.8% vs. 4.2%; 51.5% vs. 12.7%). Independent risk factors for 90-day complications were missing the first POV, coronary artery disease, and lower pre-injury status (ORs = 10.65, 2.80, 7.89, respectively). Independent risk factors for 90-day re-admission were missing the first POV, chronic obstructive pulmonary disease on home oxygen, and lower re-injury status (ORs = 8.04, 5.44, 5.47, respectively). Missing the first POV was the strongest independent risk factor for 90-day complications and 90-day readmission. Patients who miss their first POV have significantly higher 90-day and one year mortality rates.
