Formatted Abstract/Summary
Objective(s): The 2006 OARSI Guidelines for hand OA clinical trials, recognised the potential value of an aesthetic damage assessment, but acknowledged the absence of any existing outcome measure. In order to address this deficiency, a hexadimensional Patient Reported Outcome Measure (PROM) of the aesthetic impact of hand OA, termed the Hand-Osteoarthritis Aesthetic Damage Index (HADIX), has been developed.
Material & Methods: This study forms part of a larger longitudinal initiative involving clinical profiling, digital photography and radiography. Following a literature review, the prototype HADIX questionnaire was developed, piloted and refined based on a sample of subjects with hand OA, who were interviewed and responded to structured closed and open ended questions. The main study involved 52 subjects with hand OA (47 females and 5 males), fulfilling Altman Criteria for hand OA, mean age 67.4 yrs  (min048 yrs; max084 yrs; SD08.7), mean duration of hand OA symptoms 10.8 yrs (Min 0 0.25 yrs; Max045 yrs; SD09.0).
Results: HADIX1—Subject’s rated self concern (mean0 3.9), ahead of concern for others in different social settings (0-10* scale). HADIX2—Global assessment of overall appearance (mean04.5–4.8) (1–7* scale). HADIX3—Level of concern regarding joint damage/deformity (mean Left 15.3, Right 17.3) (0–64* scale). HADIX4—Subject’s ranked the relative importance of having normally appearing hands (vs. 4 other health state attainments) as low (mean 4.88) (1*–5 scale). HADIX5—Subject’s level of satisfaction with the overall appearance of OA-affected hand joints was 4.16(1–7* scale). HADIX6—Acceptability to the subject of the appearance of their hands remaining in the current state for the rest of their life (Right 82%, Left 90%). [*0high impact end of scale]
Conclusion(s): HADIX provides a novel approach to the evaluation of the aesthetic impact of hand OA. While initial observations suggest that aesthetic impact may be of lower relative importance than pain, function, stiffness and strength improvements, nevertheless HADIX 1, 2 and 3 scores suggest the aesthetic impact of hand OA is generally negative.
