Abstract

The aim of this study is to assess the potential effectiveness, acceptability and feasibility of a brief smoking cessation intervention delivered as part of cervical screening. A cluster randomised controlled trial was conducted with clinic week as the unit of randomisation, comparing a group (n=121) receiving brief smoking cessation advice supplemented with written information given by practice nurses during cervical smear test appointments, with a group (n=121) not receiving this advice. Outcomes were intention to stop smoking (potential effectiveness); intention to attend for future cervical screening (acceptability); duration of intervention (feasibility). 172/242 (71%) and 153/242 (63%) participants completed 2-week and 10-week follow-ups, respectively. Compared to women in the control group, those in the intervention group had higher intentions to stop smoking at 2-weeks (adjusted mean difference 0.51, 95% CI: -0.02 to 1.03, P=0.06) and 10-weeks (adjusted mean difference 0.80, 95% CI 0.10 to 1.50, P=0.03). The two groups had similarly high intentions to attend for future screening. Consultations in the intervention arm took a mean of 4.98 min (95% CI: 3.69 to 6.27; P<0.001) longer than the control arm. In conclusion, brief smoking cessation advice given by practice nurses as part of cervical screening seems acceptable, feasible and potentially effective. Evidence is lacking on the effectiveness and cost effectiveness of this intervention in achieving biochemically validated smoking cessation.
