Abstract
Introduction: Recently there has been much interest in minimally invasive hip surgery, with less attention being directed to maximising the potential benefits of this type of surgery. We have developed a new multidisciplinary program for patients undergoing total hip replacement in order to facilitate an overnight hip replacement service.
Methods: The program involves a pre-operative regimen of education and physiotherapy, a modified anaesthetic technique, a minimally invasive surgical approach and a portable local anaesthetic pump infusion for post-operative pain control. Strict inclusion and exclusion criteria were developed based on age, medical status and social circumstances. Patients were mobilised on the day of their operation and discharged home with an ‘outreach team’ support network. No patient complained that their discharge was too early. Independent evaluation was performed using the Oxford Hip Questionnaire, the Merle d’Aubigne clinical rating system and Visual Analogue Pain Scores.
Results: Thirty seven patients underwent total hip replacement using the new protocol.
The average length of stay was 1.2 days. The mean pain score on discharge was 1.3/10. The Oxford Hip Questionnaire and Merle d’Aubigne scores were comparable to patients who underwent surgery prior to the introduction of the new protocol. Minimising in-patient stay for total hip replacement benefits the patient by reducing exposure to nosocomial infection and expediting the return to a normal environment for faster rehabilitation. This new program allows patients undergoing total hip replacement to be discharged after 1 night post operatively without compromising safety or quality of care.
Conclusion: Minimally invasive surgery with a suitable infrastructure can be used to dramatically reduce the length of stay in suitable patients. This can be achieved reliably, safely and with high patient satisfaction. In order to gain the benefit of Minimally Invasive Surgery we recommend introducing this type of comprehensive program.
