Abstract

OBJECTIVE:

The assessment of health-related quality-of-life (HRQoL) in rheumatoid arthritis (RA) is becoming increasingly common in both research and clinical practice. One of the most widely used tools for measuring HRQoL is the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36). We conducted a systematic review examining the impact of RA on HRQoL, measured through the SF-36.

METHODS:

MEDLINE and Embase were searched for observational studies reporting mean and standard deviation scores for each domain of the SF-36 in adult RA patients. Studies were reviewed in accordance with PRISMA guidelines, and a random-effects meta-analysis was performed.

RESULTS:

In total, 31 studies were eligible for inclusion in the meta-analysis, including 22,335 patients. Meta-analyses found that pooled mean HRQoL score for the SF-36 physical component summary was 34.1 (95% CI: 22.0-46.1) and mental component summary was 45.6 (95% CI: 30.3-60.8). Increased age was associated with reduced physical function and physical component summary (PCS) scores but improved mental health and mental component summary (MCS) scores. Female gender was associated with improved scores on role physical, bodily pain and PCS but reduced mental health and MCS scores. Longer disease duration was associated with improved MCS. Patients with RA have a substantially reduced HRQoL in comparison to both other physical illnesses and in comparison to normative datasets from UK and USA populations.

CONCLUSIONS:

RA has a substantial impact on HRQoL. This supports recent NICE guidelines stipulating that RA patients should be regularly assessed for the impact their disease has on HRQoL and appropriate management provided.
