The impact of gout as described by patients, using the lens of The International Classification of Functioning, Disability and Health (ICF) : a qualitative study

Abstract

This project was supported by Arthritis New Zealand (grant reference R259 to WJT). The US data collection was funded by Pfizer (undertaken commercially by Adelphi Values). The NZ data collection was supported by the Maaori Gout Action Group of Counties Manukau District Health Board and the Auckland Rheumatology Fund (to KL). The Spanish data were collected with the direct support of the authors. The funders had no direct role in the conduct of the reported study, analysis of the data or writing of the manuscript.

The International Classification of Functioning, Disability and Health (ICF) aims to comprehensively describe the ways in which a person's health condition affects their life. This study aimed to contribute to the development of an ICF core set for gout through patient opinion derived from focus groups and interviews. We conducted a secondary qualitative analysis of data from three studies investigating the patient experience of gout. In total there were 30 individual interviews and 2 focus groups (N = 17) comprising 47 participants. We conducted thematic analysis of the textual data to extract meaning units, which were then linked to the ICF. A large number of ICF categories were relevant to patients with gout. Participants mentioned 93 third level categories, 17 of which were mentioned by more than 50% of patients. The most references for a single category was for b280, Sensation of pain, followed by personal factors (not yet categorised by the ICF). The most participants mentioned the environmental factor e355, Health professional support, followed by b280, Sensation of pain. The categories identified in this study as relevant to patients with gout highlight the severe pain associated with this disease, the impact on mobility and corresponding life areas. The roles of health professional support, medication, and personal attitudes to disease management are also reflected in the data. These results will contribute to the development of the ICF core set for gout.
