Feasibility of day-case total hip arthroplasty: a single-centre observational study.

INTRODUCTION: Recent reports indicate that total hip arthroplasty (THA) can be further accelerated and might be managed as day-case. This could provide benefits to health care expenditure, lower patient risks and change patient satisfaction. We evaluated the feasibility, efficacy, safety and patient satisfaction of same-day (<12 hours) THA operation and discharge.

METHODS: Consecutive patients were screened for eligibility (primary THA, ASA 1 or 2 physical status) and the presence of a support person to follow the patient for 48 hours postoperatively in an observational study. THA was managed as day-case (<12 hours) through patient selection, preoperative patient education programme, light spinal anaesthesia, low opioid usage, and early mobilisation. Efficacy and logistics were analysed and compared to current accelerated practice. Patient satisfaction was compared to existing fast-track THA and elective surgery cohorts.

RESULTS: 29 consecutive patients were screened and 20 participated (69%). 17/20 patients (85%) were released on the day of surgery. There were no serious adverse events or complications, and no infections or readmission at 6-week follow-up. Patient overall satisfaction rating (1-5) was high (4.75), higher than in a 301-patient cohort (4.53) (THA and total knee arthroplasty) from the same centre (p = 0.23), and higher than in a national, elective surgery cohort (4.3) (p = 0.04).

CONCLUSIONS: We report the feasibility of day-case THA. Safety, complications and overall patient acceptance were satisfactory. Light spinal anaesthesia facilitated quick transit through postanaesthesia care unit to early mobilisation. Support persons and patient education may play a part in high patient acceptance of day-case surgery.
