Abstract

Background
Gout affects 2.5% of adults in the UK but is often poorly managed. It can impair health-related quality of life (HRQOL), yet little is known about which people with gout are at risk of worse outcomes. We investigated factors associated with change in HRQOL over a three-year period in people living with gout in primary care.

Methods
People with gout registered with 20 general practices in the West Midlands completed the Gout Impact Scale (GIS), Short-Form-36 Physical Function subscale (PF10) and health assessment questionnaire disability index (HAQ-DI) at five time-points (baseline & 6, 12, 24 and 36 months) via postal questionnaire. Linear mixed modelling (LMM) with multivariate adjustment for baseline and time-varying covariates was used to investigate gout-specific, comorbid and socio-demographic factors associated with change in the Concern Overall (GIS-CO), PF10 and HAQ-DI over three years. Higher scores are worse for GIS-CO and HAQ-DI, but better for PF10.

Results
Of 1,184 baseline respondents, 818 (80%), 721 (73%), 696 (75%), 605 (68%) responded at 6, 12, 24 and 36 months respectively. Mean age (SD) at baseline was 65.6 (12.5) years. 990 (84%) were male, 494 (42%) reported >2 gout flares in the previous year, 624 (54%) were taking allopurinol and 318 (27%) had an eGFR<60mL/min/1.73m2. Factors identified as being associated with a deterioration in HRQOL over three years (table), were gout flare frequency (GIS-CO, PF10), history of oligo/polyarticular flares (GIS-CO, HAQ-DI), having a flare currently (GIS-CO), allopurinol use (PF10), having body pain (GIS-CO, PF10, HAQ-DI), higher pain severity (GIS-CO, PF10, HAQ-DI), number of comorbidities (PF10), eGFR <60mL/min/1.73m2 (PF10, HAQ-DI), anxiety (GIS-CO), depression (PF10, HAQ-DI), and older age (PF10, HAQ-DI). Factors associated with an improvement in HRQOL were longer gout duration (GIS-CO), older age (GIS-CO), lower socioeconomic deprivation (PF10, HAQ-DI) and more frequent alcohol consumption (PF10, HAQ-DI).
