Abstract

Background: Discharge to an inpatient care facility (skilled-care or rehabilitation) has been shown to be associated with adverse outcomes following elective total joint arthroplasties. Current evidence with regard to hip fracture surgeries remains limited.

Methods: The 2015-2016 ACS-NSQIP database was used to query for patients undergoing total hip arthroplasty, hemiarthroplasty and open reduction internal fixation for hip fractures. A total of 15,655 patients undergoing hip fracture surgery were retrieved from the database. Inpatient facility discharge included discharges to skilled-care facilities and inpatient rehabilitation units. Multi-variate regression analysis was used to assess for differences in 30-day post-discharge outcomes between home-discharge versus inpatient care facility discharge, while adjusting for baseline differences between the 2 study populations.

Results: A total of 12,568 (80.3%) patients were discharged to an inpatient care facility. Discharge to an inpatient care facility was associated with higher odds of any complication (OR 2.03 [95% CI, 1.61-2.55]; p < 0.001), wound complications (OR 1.79 [95% CI, 1.10-2.91]; p = 0.019), cardiac complications (OR 4.49 [95% CI, 1.40-14.40]; p = 0.012), respiratory complication (OR 2.29 [95% CI, 1.39-3.77]; p = 0.001), stroke (OR 7.67 [95% CI, 1.05-56.29]; p = 0.045, urinary tract infections (OR 2.30 [95% CI, 1.52-3.48]; p < 0.001), unplanned re-operations (OR 1.37 [95% CI, 1.03-1.82]; p = 0.029) and readmissions (OR 1.38 [95% CI, 1.16-1.63]; p < 0.001) following discharge.

Conclusion: Discharge to inpatient care facilities versus home following hip fracture surgery is associated with higher odds of post-discharge complications, re-operations and readmissions. These results stress the importance of careful patient selection prior to discharge to inpatient care facilities to minimise the risk of complications.

Keywords: 30-day readmissions; Discharge destination; hip fracture; reoperations.
