The "Hip-in-a-Day" program enables same-day discharge for select hip replacement patients, significantly reducing hospital stays. This ultra-fast-track approach demonstrates high patient satisfaction and feasibility for routine care.
Area of Science:
- Orthopedic Surgery
- Arthroplasty
- Patient Care Pathways
Background:
- Average hip replacement length of stay in Germany was 10.2 days in 2017.
- Our hospital reduced average stay to 3.8 days over 10 years.
- Development of an ultra-fast-track program for hip arthroplasty.
Purpose of the Study:
- Present the philosophy, treatment principles, and daily routine of the 'Hip-in-a-Day' program.
- Detail the pre-, intra-, and postoperative phases of the ultra-fast-track pathway.
- Discuss challenges within the German healthcare system for short-stay hip arthroplasty.
Main Methods:
- 97 patients (43-77 years) underwent the 'Hip-in-a-Day' pathway from Sep 2015 to Nov 2019.
- All patients received general anesthesia and direct anterior approach (DAA) hip surgery.
- Patients discharged within 24 hours; 30 on surgery day (12h avg), 67 next day (20h avg).
Main Results:
- All 97 patients met discharge criteria within 24 hours.
- 98.9% (96/97) completed the program without readmission.
- 100% patient satisfaction reported with the fast discharge process.
Conclusions:
- 'Hip-in-a-Day' aims for discharge within 24 hours post-surgery.
- Successful implementation relies on interdisciplinary care, anesthesiology, minimally invasive surgery, and patient compliance.
- Ultra-fast-track arthroplasty is feasible, yielding high patient satisfaction; calls for inclusion in DRG system for reimbursement.
