Efficacy of a tobacco quitline among adult cancer survivors.

ABSTRACT: The purpose of the study (conducted 2010-2013) was to determine the efficacy of two common types of tobacco quitlines in adult cancer survivors who regularly smoked cigarettes.Adult onset cancer survivors in Memphis, Tennessee (n=427, 67% female, 60% Caucasian) were randomized either to a Proactive (i.e., counselor-initiated calls) or Reactive (i.e., participant-initiated calls) quitline. Both conditions also received nicotine replacement therapy. The primary outcome was biochemically-verified (i.e., salivary cotinine) smoking cessation.While 12-month self-reported abstinence was consistent with other published studies of smoking cessation (22% and 26% point prevalence abstinence for Proactive and Reactive conditions, respectively), 48% of participants who were tested for cotinine failed biochemical verification, indicating a considerable falsification of self-reported cessation. Adjusted cessation rates were less than 5% in both intervention conditions.Our results are consistent with other studies indicating that traditional smoking cessation interventions are ineffective among cancer survivors. Moreover, self-reports of cessation were unreliable in cancer survivors participating in a quitline intervention, indicating that future studies should include biochemical verification. Given the importance of smoking cessation among cancer survivors and low cessation rates in the current study, it may be necessary to design alternative interventions for this population.

Project description:IntroductionQuitlines are effective in helping smokers quit, but pediatrician quitline referral rates are low, and few parents who smoke use the service. This study compared enrollment of parents who smoke in the quitline using electronic referral with that using manual referral.Study designThe study was designed as a pragmatic RCT.Setting/participantsParticipants were recruited from one large, urban pediatric primary care site in Philadelphia, Pennsylvania with a high percentage of low-income families. Participants included adult parents who smoked and were present at their child's healthcare visit.InterventionPediatricians screened for tobacco use; smokers were given brief advice to quit and, if interested in quitting, were referred to the quitline. The eReferral ("warm handoff") involved electronically sending parent information to the quitline (parent received a call within 24-48 hours). Control group procedures were identical to eReferral, except the quitline number was provided to the parent. Data were collected between March 2017 and February 2018 and analyzed in 2018.Main outcome measuresThe primary outcome was the proportion of parents enrolled in quitline treatment. Secondary outcomes included parent factors (e.g., demographics, nicotine dependence, and quitting motivation) associated with successful enrollment. Number of quitline contacts was also explored.ResultsDuring the study period, in the eReferral group, 10.3% (24 of 233) of parents who smoked and were interested in quitting enrolled in the quitline, whereas only 2.0% (5 of 251) of them in the control group enrolled in the quitline-a difference of 8.3% (95% CI=4.0, 12.6). Parents aged ≥50 years enrolled in the quitline more frequently. Although more parents in the eReferral group connected to the quitline, among parents who had at least one quitline contact, there was no significant difference in the mean number of quitline contacts between eReferral and control groups (mean, 2.04 vs 2.40 calls; difference, 0.36 [95% CI=0.35, 1.06]).ConclusionsSmoking parent eReferral from pediatric primary care may increase quitline enrollment and could be adopted by practices interested in increasing rates of parent treatment.Trial registrationThis study is registered at www.clinicaltrials.gov NCT02997735.
