What we know Arthroplasty numbers keep increasing Physiotherapy is beneficial after arthroplasty Home-based rehabilitation is just as beneficial as supervised rehabilitation, including inpatient rehabilitation
What we don t know 1. The proportions of Australia arthroplasty patients receiving home-based program 2. Differences in physiotherapy participation between the public and private sector 3. The costs associated with physiotherapy participation to the funding system
Methods A multicentre prospective observational study, EPOC (Evidence-Based Processes and Outcomes of Care) involving 19 high volume public and private orthopaedic centres in Australia Enrolled primary total hip (THA) or total knee (TKA) arthroplasty patients with osteoarthritis Demographic details, medical history, baseline function and surgical data were obtained preoperatively with standardised pro-formae Telephone follow-up conducted at 35 and 90 days post-surgery evaluated rehabilitation received (type, duration, frequency) and complications information
Methods -continued Physiotherapy could be Inpatient rehabilitation only Inpatient rehabilitation and supervised outpatient sessions Supervised Outpatient sessions only Home-based program, monitored (up to two supervised session) or un-monitored Costs (2014/15 AUD) Inpatient rehabilitation per day = $967.29 (Australian Public Hospital Cost Report, 2013) Supervised outpatient per session = $74.90 (Commcare, 2015)
Results Cohort of 1618 patients Hip Replacement (THA) Knee Replacement (TKA) Public Funding Private Insurance Total 283 502 785 329 504 833 n=1618 Majority were female, elderly, overweight and had co-morbidities in both THA and TKA groups Public patients had higher BMI, shorter median lengths of stay after the procedure and more other lower limb and back problems. In the TKA group, public patients also had greater level of comorbidity. No differences were noted in age, gender, ASA score or surgical hip approach between public and private patients

Results Whole Cohort cont. No difference in major post-discharge complications between patients who had home based programs and those who had supervised therapy (11.7% vs. 9.8%, p=0.498). Public patients had fewer outpatient sessions, but longer lengths of stay in inpatient rehabilitation Curiously, 18% of THA and 34% of TKA patients were continuing supervised physiotherapy at 10 weeks (no difference between public/private).
Are there reasons to have supervised therapy???

What does it mean? A minority of patient receive the physiotherapy recommended by best practice evidence This costs Australian health systems millions of dollars Reconciling this evidence-practice gap is important in maintaining the sustainability of both public and private health systems in the face of increasing numbers of joint replacements
