['Hip-in-a-Day'].

backgroundIn 2017, the average length of stay for primary hip replacement patients in Germany was 10.2 days. In our hospital, we have been able to reduce the length of stay in the last 10 years to an average of 3.8 days.

objectivesSince September 2015, we offer the 'Hip-in-a-Day' program. This ultra-fast-track pathway consists of a hip arthroplasty procedure with the same day discharge of a well-prepared and explicitly selected patient with maximum intensive interdisciplinary care. The aim is to present the philosophy, treatment principles and daily routine during the pre-, intra- and postoperative phase. The challenges in the German health care system will be discussed. MATERIAL AND

methodsFrom September 2015 to November 2019, we operated on 97 patients (50 F: 47 M, ages: 43-77 years, ⌀ 55 years) who had undergone the Hip-in-a-Day pathway. All 97 patients received general anesthesia. Surgery was performed via the direct anterior approach (DAA) to the hip. Patients stayed in the day clinic less than 24 h after surgery. Of these, 30 patients were discharged on the day of surgery (⌀ 12 h stay), and 67 patients left the clinic the day after the operation (⌀ 20 h stay). Due to integrated health-care contracts with health-care providers, we were eligible to receive bundled reimbursement for this patient population.

resultsAll 97 patients completed the Ultra-Fast-Track pathway and were able to meet the discharge criteria within 24 h after surgery. 96 of the 97 (98.9%) patients were able to complete Hip-in-a-Day without readmission. One patient had to undergo revision surgery after 10 days due to cup loosening. All patients (100%) were very satisfied with the routine of the day and the fast discharge from the hospital.

conclusionThe aim of Hip-in-a-Day is to discharge patients within 24 h after surgery. The implementation of the setup at the day clinic is intensive interdisciplinary care of all participating departments, as well as the three cornerstones of anesthesiological management, minimally invasive surgical techniques and patient compliance. In our clinic, ultra-fast-track arthroplasty is routinely feasible and has produced great patient satisfaction. Statutory health-care providers should include short-stay hip arthroplasty into the DRG system, so that this care concept can be reimbursed and practiced nationwide in Germany.
