Study information
| Study design | The trial is a pragmatic, randomised, single blind study and a pilot for a potentially larger project. |

| Primary study design | Interventional |
| Secondary study design | Randomised controlled trial |

| Study type | Quality of life |
| Scientific title | |
| Study acronym | 7OAKS-ESCAPE |
| Study hypothesis | 1. For patients with chronic knee pain a rehabilitation regimen delivered in the community with regular follow-up reduces pain and disability better than routine physiotherapy and these benefits are maintained over time 2. The rehabilitation regimen reduces healthcare utilisation and is ultimately less costly than routine physiotherapy |
| Ethics approval(s) | The study was approved by the Maidstone & Tunbridge Wells Local Ethics Committee on the 18th December 2003 (ref: 149/9/03). |
| Condition | Chronic knee pain, osteoarthritis |
| Intervention | Interventions: Group one: Innovative exercise and education programme - this is a course of ten sessions each consisting of some education and some exercise Group two: Routine physiotherapy Outcome evaluation: Outcome measures at baseline and at 12-month follow-up assessment will be summarised using appropriate descriptive statistics. Primary analyses will be by intention-to treat. The level of significance will be set at p<0.05. The effect of the intervention on the Western Ontario and McMasters Universities Osteoarthritic Index (WOMAC) functional score will be assessed, first, by investigating whether outcomes differ significantly overall by groups. These analyses will be adjusted for baseline measures. The following additional analyses are planned. Two tests of interaction will be carried out to investigate whether the effect intervention is influenced by: 1. Depression (Hospital Anxiety and Depression [HAD] score), or 2. Self-efficacy (Arthritis Self-Efficacy Score) For all outcomes, both unadjusted (adjusting only for the baseline measure) and adjusted analyses (adjusting for other potential confounding factors) will be carried out; the latter will be interpreted as 'sensitivity analyses' to explore the robustness of the unadjusted analyses to possible confounding. Finally, process variables characterising the success with which the intervention was delivered (e.g. compliance) will be included in analyses of WOMAC functional score only, in order to interpret better the overall effects of the intervention. Economic evaluation: The primary economic evaluation will be a cost-effectiveness analysis comparing changes in the primary outcome (WOMAC) and total societal costs for each group. The secondary economic evaluation will be a cost-utility analysis based on utility weights associated with EuroQoL Health Survey (EQ-5D) health states. Cost-effectiveness acceptability curves will be employed for both the cost-effectiveness and cost-utility analyses in order to better inform decisions about the relative cost-effectiveness of the three treatments. Supplementary evaluation will take the form of a cost-consequences analysis, examining total and component costs alongside all outcomes. The data analyses would be conducted in a manner consistent with those employed in the clinical evaluation (for example, on an intention-to-treat basis, and adopting the same conventions with respect to cluster randomisation, missing items scores, missing observations etc.). Cost differences between groups will be tested using the student's t-test. Cost data are often skewed, violating the normality assumption underpinning the validity of the t-test. If this is the case, bootstrap replications of the original data will be performed to check the robustness of the t-test results. Sensitivity analyses will be performed to check the assumptions made in the cost calculations and analyses. In addition, the EuroQoL will enable calculation of cost per Quality Adjusted Life Year (QALY) for the interventions. |
