Abstract: OBJECTIVE: We previously demonstrated the efficacy of a 6 week home based physical therapy (PT) intervention for people with moderate to severe rheumatoid arthritis (RA). This followup study determined if short term improvements were maintained to one year. METHODS: Participants in the short term study were randomly assigned to receive a PT intervention (education, exercise, and pain relief modalities) delivered by physiotherapists with advanced rheumatology training (Weeks 0 to 6) or to a wait list control group. The control group received the intervention between Weeks 6 to 12. Outcome measures included the Stanford Arthritis Self-Efficacy Scale (SES), the Arthritis Community Research and Evaluation Unit Rheumatoid Arthritis Knowledge Questionnaire (KQ), and a visual analog scale for pain. Disease activity measures (tender joints, grip strength, and morning stiffness) were also included. MANOVA was used to compare within-subject scores at baseline and at 12 and 52 weeks. Paired t tests were used to determine if 12 week changes were maintained at 52 weeks. RESULTS: Of the 127 protocol completers, 117 (92.1%) were available for the one year followup. For those measures that showed significant improvement in the randomized controlled trial (SES, KQ, morning stiffness), improvements at 12 weeks were maintained at 52 weeks (p > 0.010). CONCLUSION: Subjects who participated in a short term home based PT intervention delivered by specially trained therapists reported improved outcomes following treatment, and these improvements were maintained at one year followup. Future studies need to explore the relative contributions of education, exercise, home based care, therapist training, and reinforcement strategies in improving longterm outcomes in RA.

Abstract: OBJECTIVE: To estimate the incremental cost-effectiveness (ICE) of services from a primary therapist compared with traditional physical therapists and/or occupational therapists for managing rheumatoid arthritis (RA), from the societal perspective. METHODS: Patients with RA were randomly assigned to the primary therapist model (PTM) or traditional treatment model (TTM) for approximately 6 weeks of rehabilitation treatment. Health outcomes were expressed in terms of quality-adjusted life years (QALYs), measured with the EuroQol instrument at baseline, 6 weeks, and 6 months. Direct and indirect costs, including visits to health professionals, use of investigative tests, hospital visits, use of medications, purchases of adaptive aids, and productivity losses incurred by patients and their caregivers, were collected monthly. RESULTS: Of 144 consenting patients, 111 remained in the study after the baseline assessment: 63 PTM (87.3% women, mean age 54.2 years, disease duration 10.6 years) and 48 TTM (79.2% women, mean age 56.8 years, disease duration 13.2 years). From a societal perspective, PTM generated higher QALYs (mean +/- SD 0.068 +/- 0.22) and resulted in a higher mean cost ($6,848 Canadian, interquartile range [IQR] $1,984-$9,320) compared with TTM (mean +/- SD QALY -0.017 +/- 0.24; mean costs $6,266, IQR $1,938-$10,194) in 6 months, although differences were not statistically significant. The estimated ICE ratio was $13,700 per QALY gained (95% nonparametric confidence interval -$73,500, $230,000). CONCLUSION: The PTM has potential to be an alternative to traditional physical/occupational therapy, although it is premature to recommend widespread use of this model in other regions. Further research should focus on strategies to reduce costs of the model and assess the long-term economic consequences in managing RA and other rheumatologic conditions.

Abstract: OBJECTIVE: To compare the primary therapist model (PTM), provided by a single rheumatology-trained primary therapist, with the traditional treatment model (TTM), provided by a physical therapy (PT) and/or occupational therapy (OT) generalist, for treating patients with rheumatoid arthritis (RA). METHODS: Eligible patients were adults requiring rehabilitation treatment who had not received PT/OT in the past 2 years. Participants were randomized to the PTM or TTM group. The primary outcome was defined as the proportion of clinical responders who experienced a > or =20% improvement in 2 of the following measures from baseline to 6 months: Health Assessment Questionnaire, pain visual analog scale, and Arthritis Community Research and Evaluation Unit RA Knowledge Questionnaire. RESULTS: Of 144 consenting patients, 33 (10 PTM participants, 23 TTM participants) dropped out without completing any followup assessment, leaving 111 for analysis (63 PTM participants, 48 TTM participants). The majority were women (PTM 87.3%, TTM 79.2%), with a mean age of 54.2 years and 56.8 years for the PTM and TTM groups, respectively. Average disease duration was 10.6 years and 13.2 years for each group, respectively. At 6 months, 44.4% of patients in the PTM group were clinical responders versus 18.8% in the TTM group (chi(2) = 8.09, P = 0.004). CONCLUSION: Compared with the TTM, the PTM was associated with better outcomes in patients with RA. The results, however, should be interpreted with caution due to the high dropout rate in the TTM group.

Abstract: OBJECTIVE: To assess the difference in costs of home-based versus clinic-based physiotherapy (PT) for patients with rheumatoid arthritis (RA) from a societal perspective. METHODS: A cost analysis was performed using statistical and financial information provided by The Arthritis Society, Ontario Division, from April 1, 1997 to March 30, 1998. Cost estimates included treatment costs and costs borne by patients. A sensitivity analysis was conducted to examine the effect of altering the valuation of treatment time and patient employment status. RESULTS: Total costs per case were $210.87 for the home setting, and $183.87 for the clinic setting when patients were employed. Sensitivity analysis did not change the trend of the results. The estimated start-up costs for an arthritis clinic were between $302.90 and $652.40. From the perspective of the health care system, these costs would be recovered after serving 4 to 8 RA patients at a clinic. CONCLUSION: The findings suggest that ambulatory PT care is less costly than home-based services for people with RA based on The Arthritis Society model. Further studies should be conducted to examine the effectiveness and the possible adverse consequences of alternative settings for service delivery.
