An Integrated Self Management Programme to Improve Outcomes in Patients With Hand Osteoarthritis (OASIS-H)

Hand OsteoArthritis Self-management and Integrated Scheme (OASIS-H) to Improve Outcomes in Patients With Hand Osteoarthritis

The goal of this trial is to evaluate the efficacy of an integrated self-management programme in improving clinical outcomes in patients with hand osteoarthritis (OA).

This is an open-labelled, randomized controlled trial with an objective to determine the efficacy of an integrated self-management programme versus routine clinical care for participants with symptomatic hand OA.

Participants will be randomized into early intervention group and routine clinical care groups in a 1:1 ratio. Patients who randomized into early intervention group will receive 8 week integrated self-management programme delivered by occupational therapists and rheumatology nurse on hand OA management. Patients who randomized into routine clinical care group will receive usual clinical care for OA for 26 weeks and then receive an identical 8 weeks integrated self-management programme. The primary outcome is the improvement in pain at 26 weeks between the two groups.

Study Overview

• Status: Not yet recruiting
• Conditions: Hand Osteoarthritis
• Intervention / Treatment: Behavioral: Integrated self-management programme

Detailed Description

Background: Osteoarthritis (OA) of the hand is a common and potentially disabling condition with increasing prevalence in Hong Kong due to an aging population. The direct and indirect economic burden due to OA are substantial and this calls for an unmet need for more effective management for hand OA. Hand OsteoArthritis Self-management and Integrated Scheme (OASIS-H) is a self-management programme integrated with occupational therapy and rheumatology nurse education with an aim to improve outcomes in patients with hand osteoarthritis.

Objective: This is an open-labelled, randomized controlled trial to determine the efficacy of an integrated self-management programme versus routine clinical care for participants with symptomatic hand OA.

Hypothesis: The integrated programme will be more efficacious than routine clinical care in reducing pain and improving function in symptomatic OA hand in 6 months.

Methods: Consecutive patients who fulfilled the American College of Rheumatology Classification Criteria for hand OA with a pain score of ≥40 out of 100mm on visual analogue scale (VAS) will be included. Patient with secondary OA hand, unable to sign consent and with the use of systemic corticosteroid within 6 months will be included. Participants will be randomized in a 1:1 ratio into early intervention and routine clinical care groups. In the early intervention group, patients will participate in an eight-week integrated hand OA management programme within 1 month from randomization. The programme will consist of three self-management education sessions conducted by the occupational therapists and rheumatology nurses on pain management strategy, joint protection, group sharing and exercise, one telemedicine session, aids prescription and splintage fabrication. For patients randomized into the routine clinical care group, they will continue to receive routine medical care from the rheumatology clinic. At 6 months after randomization, patients in the routine clinical care group will crossover and receive an identical 8-week integrated hand OA management programme as the early intervention group. The primary endpoint is the change in finger pain in pain VAS at 6 months from baseline. Secondary endpoints include change in function measured by the functional index for functional index for hand OA, Short form health survey and health assessment questionnaire disability index, change in hand grip strength and dexterity at 6 months and 12 months. The primary endpoint will be analyzed by linear mixed models and the differences in pain over time between the two groups will be compared using linear regression model.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Pain visual analogue scale (VAS)	Pain VAS reflects the severity of pain in a score of 0-100. A lower score indicates less pain.	26 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in pain Visual Analogue Scale (VAS)	Pain VAS reflects the severity of pain in a score of 0-100. A lower score indicates less pain.	12weeks, 52 weeks
Change in Functional index hand osteoarthritis (FIHOA)	FIHOA reflects hand function with a score of 0 to 30. A lower score indicates better hand function	12 weeks, 26 weeks, 52 weeks
Change in Quick Disabilities of the Arm, Shoulder, and Hand (DASH) score	QuickDASH is a self-reported 11-itemed questionnaire in which the response options are presented as 5-point Likert scales. At least 10 of the 11 items must be completed for a score to be calculated and the scores range from 0 (no disability) to 100 (most severe disability)	12 weeks, 26 weeks, 52 weeks
Change in Australian/Canadian Hand Osteoarthritis Index (AUSCAN) 3.1	AUSCAN 3.1 hand osteoarthritis index is a self-administered questionnaire that assesses the three dimensions of pain, disability and joint stiffness in hand osteoarthritis using a battery of 15 questions. The score is expressed in 3 subscores: AUSCAN pain score (0 (least painful)-100 (most painful), the AUSCAN stiffness score (0: least stiffness-100: most stiffness), the AUSCAN function score (0: least function impairment-100: most severe function impairment)	12 weeks, 26 weeks, 52 weeks
Change in Short-form 36 items health survey	Short-form 36 items health survey measures 8 domains of health related quality of life. The score is expressed in 0 - 100. The higher the score the less disability i.e., a score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability.	26 weeks, 52 weeks
Change in hand grip strength	Hand grip strength measured by dynamometer	26 weeks, 52 weeks
Change in hand dexterity measurement	Hand dexterity measurement	26 weeks, 52 weeks
Radiographic changes	Measured by hand plain radiographs	52 weeks

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Adverse events	Adverse events	up to 52 weeks
Use of rescue pain medication	Use of rescue pain medication e.g. NSAIDS / steroids	up to 52 weeks
