IntroductionThe aim of this study was to evaluate the impact of a pre-operative education programme on length of hospital stay after surgery for primary and revision knee arthroplasty patients. The programme was introduced at our hospital in October 2006 to encourage patients to play an active role in their recovery process after surgery.Patients And MethodsA multidisciplinary team educated knee arthroplasty patients about their care pathway, knee surgery, pain management, expected discharge goals, in-patient and out-patient arthroplasty rehabilitation. Prospective data were collected from 472 consecutive patients who underwent (primary or revision) knee arthroplasty in the period between January 2006 and November 2007. Patients were separated into two groups, one that received conventional pre-operative treatment (n = 150; Conventional group) and another that received the pre-operative education (n = 322; Education group). Length of hospital stay was compare using the Mann Whitney U test. In-patient complications, hospital re-admissions within 24 h and 3 months of hospital discharge were compared using the chi-squared test.ResultsThe mean length of stay was significantly reduced from 7 days in the Conventional group to 5 days in the Education group (P < 0.01). In addition, 20% more patients were discharged early (within 1-4 days) in the Education group compared to the Conventional group (P < 0.01). There was no difference in the percentage of in-patient complications and re-admissions in 24 h (P = 1.00) and 3 months of discharge (P = 0.92) between the two groups.ConclusionsThe results suggest that pre-operative education is a safe and effective method of reducing length of stay for knee arthroplasty patients.
