Smoking adversely influences comorbidities in rheumatoid arthritis (RA). The aim of this pilot study was to investigate whether smoking cessation is increased following a 3-month smoking cessation intervention tailored for people with RA.
39 current smokers with RA were recruited. Participants were randomized to receive the current local standard of care for smoking cessation (ABC: brief advice and subsidised nicotine replacement therapy) (control), or ABC+ additional smoking cessation advice for 3 months including face-to-face, telephone and email contact (intervention). Advice was tailored to participants' specific needs from a range of intervention tools focused on education about smoking and RA, pain control, exercise, coping, and support. The primary outcome was smoking cessation at 6 months. The secondary outcome was sustained reduction in smoking at 6 months. Disease and psychosocial characteristics of quitters and non-quitters were examined.
The overall smoking cessation rate was 24%. There was no significant difference in smoking cessation rates between the ABC and ABC+ groups (21% vs 26%; P=0.70). The mean number of cigarettes smoked daily reduced by 44% (P<0.001) but did not differ between ABC and ABC+ groups (mean reduction 47% vs 41%; P=0.72). Successful quitters had more years in education and had smoked less across their lifetime, but these differences were not statistically significant.
Smoking cessation in RA may lead to a reduced comorbid burden. The lack of added benefit of the tailored intervention suggests brief advice and NRT currently the best practice supporting people with RA who wish to quit smoking. This article is protected by copyright. All rights reserved.
