Abstract | BACKGROUND AND OBJECTIVES: Quitting smoking after being diagnosed with
cancer could reduce the risk of disease advancement, minimize adverse treatment-
related effects, improve prognosis, and enhance the quality of life. Nevertheless,
many patients continue smoking after the diagnosis of cancer. We tested the
effectiveness of a smoking cessation intervention using risk communication approach
to help cancer patients quit smoking. METHODS: A randomized controlled
trial was conducted on 528 patients who continued smoking and had medical follow-
up at the out-patient clinics of the five major acute hospitals in Hong Kong,
with 268 randomly assigned into the experimental and 260 into the control group.
Subjects in the experimental group received health warnings of smoking based on
a specially designed leaflet and patient-centred counselling from a nurse counsellor
with emphasis on risk perceptions of smoking to cancer prognosis. Subjects in
the control group received only usual care. All were followed up by telephone at
1week, 1 month, 3 months, 6 months and 12 months to assess smoking status.
FINDINGS: About 72.9% of cancer patients were in the pre-contemplation stage of
quitting at baseline. On average, they smoked 13 cigarettes per day for more than
42 years with moderate nicotine dependence. The average age of the patients was
58.9 and more than 80% of them were male. No significant differences were found
in 6-month (15.7% vs 16.5%; p=0.78) and 12-month (14.9% vs 20.4%; p=0.10)
self-reported 7-day point-prevalence smoking abstinence between the intervention
and control group. However, difference was observed in self-reported 6-month
smoking reduction by at least 50%: 16.8% of patients in the intervention group and
12.3% in the control group reported reduced smoking at 6 months (Odds Raito
1.44; 95% CI 0.89-2.35; p=0.14). CONCLUSION: This risk communication intervention
was not effective for quitting but did increase smoking reduction in cancer
patients. Very few smoking cessation programs target cancer patients, and very
few healthcare professionals help this vulnerable group to quit smoking. Further
trials on more effective smoking cessation interventions are needed. |
