Abstract 3736: Assessment of tobacco use within 30 days increases referral for cessation support

Abstract

Background: Cancer patients who self-report tobacco use within the past 30 days are at high risk for relapse and benefit from cessation support. However, there is little data on whether assessment of tobacco use within the past 30 days increases referral rates to a cessation program across cancer disease sites. Methods: Structured tobacco assessments were administered to 426 new adult patients in a Radiation Oncology clinic at a single institution. Multiple logistic regression was used to assess if clinical aspects of cancer diagnosis (age, gender, race, disease site [head/neck or thoracic {HNT} vs. other], stage [advanced vs. early], and purpose [curative vs. palliative]) affected cessation service referral rates identified using assessment of tobacco use within the past 30 days. Results: Complete medical and tobacco use data were compiled for 387 adult cancer patients (91%). Of these, 147 (38%) were women, 259 (67%) were Caucasian, 115 (30%) were black, 177 (46%) were diagnosed with HNT cancer, and 289 (74%) were being considered for curative cancer treatment. Ever smoking was reported in 273 patients (71%), and 83 (21%) reported current smoking everyday or some days. In 180 former smokers who reported time since last cigarette, 21 (12%) reported smoking within with past 30 days and 9 (7%) of these reported smoking within the past day or week. In 21 patients who were identified for cessation support through evaluation of smoking within the past 30 days, 6 (29%) were women, 7 (33%) were black, 15 (71%) were being considered for curative treatment, and 15 (71%) were diagnosed with a HNT cancer. Multiple logistic regression identified that younger age (10 yr OR 2.41, 95% CI 1.47 - 3.98) and HNT cancer (OR 8.13, 95% CI 2.2-30.3) but not gender, race, stage, and purpose were significantly associated with referral based on assessment of tobacco use within the past 30 days. Identification of smoking within the past 30 days increased cessation referrals by 25% from 83 to 114 patients. Conclusions: Assessment of tobacco use within the past 30 days increased referrals to a smoking cessation program from a Radiation Oncology clinic using a standardized tobacco assessment. In clinical trials and practice, including this question has particular benefit for younger patients and patients with head/neck or thoracic tumors.
