Qualitative study informing the development and content validity of the HAND-Q: A modular patient-reported outcome measure for hand conditions

Objectives The purpose of this study was to identify and understand the issues that are relevant to patients with hand conditions. The data were used to develop a patient-reported outcome measure (PROM) for adults with hand conditions (HAND-Q) and refine it with input from patients and clinician experts. Design Semistructured qualitative interviews were used to understand what matters to patients. Cognitive debriefing was used to refine preliminary HAND-Q scales. Setting Hand clinics in tertiary healthcare centres in Canada, Australia and USA. Participants Eligible participants were English-speaking adults who had experienced hand surgery in the preceding 12 months and were at least 4 weeks post-hand surgery A total of 62 in-depth interviews (females, n=34; mean age=65 years) were conducted to develop an item pool and draft the HAND-Q scales. The preliminary scales were refined through cognitive debriefing interviews with 20 participants and feedback from 25 clinician experts. All interviews were audiorecorded, transcribed verbatim and coded using a line-by-line approach. Results Qualitative data were organised into two top-level domains of health-related quality of life and satisfaction with treatment outcomes. The scales were refined iteratively, and the field-test version included 319 unique items and 20 independently functioning scales. Conclusions The HAND-Q is a comprehensive PROM developed using extensive patient and clinician expert input, following established guidelines for PROM development and validation. In the next phase, the psychometric properties of the HAND-Q will be established in an international field test, following which the HAND-Q will be available for use in clinical research and practice.
