24 hours stay after hip replacement – Implementation of a patient-centered time-based fast-track program

Background and purpose — The length of stay after total hip arthroplasty has been reduced to 2–4 days after implementing fast-track surgery. We investigated whether a new time-based patient-centered primary direct anterior approach (DAA) total hip arthroplasty (THA) treatment protocol in a specialized clinic, with a planned length of stay of about 24 hours, could be achieved in all patients or only in a selected group of patients.

Patients and methods — We analyzed prospectively collected data in a cohort of 378 consecutive patients who underwent a primary direct anterior THA as a patient-centered time-based procedure between March 1, 2012 and December 31, 2015. Patients with complicated medical comorbidity and those over the age of 85 were excluded from the study. The average length of stay was recorded and all complications, re-admissions, and reoperations were registered and analyzed. The primary outcome measures were length of stay and complication rate, at discharge and 90 days postoperatively.

Results — The average length of stay for all patients was 26 hours. All patients were discharged from the clinic on the day after the operation and were able to continue their recovery at home or in a rehabilitation facility. The overall complication rate within 3 months of surgery was 6%. The 3-month re-admission rate and the 3-month reoperation rate were both 2%.

Interpretation — Performing a time-based, patient-centered fast-track program for DAA total hip arthroplasty can result in a standardized length of stay of about 24 hours and a high level of patient satisfaction with few complications, re-admissions, and reoperations.
