The relationship between type of telephone service and smoking cessation among rural smokers enrolled in quitline tobacco dependence treatment

摘要

Quitlines are successful tools for smoking cessation, but no known study has examined whether type of phone service (cell phone only (CPO) vs. landline (LL)) impacts quitline utilization, quit attempts, and sustained cessation. This report details an observational study examining the association between phone service and quitline utilization and cessation among Ohio Appalachian adults willing to quit smoking and enrolled in a cessation trial from 2010 to 2014. A secondary analysis was conducted with data obtained from smokers enrolled in the Ohio Tobacco Quitline arm of a group randomized trial (n=345). The intermediate outcome variables included number of calls, cumulative total call length, average call length, verified shipments of NRT, and 24-hour quit attempt. The primary outcome measure was biologically confirmed 7-day point prevalence abstinence from tobacco at 3, 6, and 12months post treatment. Participants with LL service, on average, made almost one more call to the quitline and spoke 17.2min longer over the course of treatment than those with CPO service. Those with LL service were more likely to receive a second 4-week supply of NRT. Phone service status was not associated with average quitline call length, receiving at least one NRT shipment, having made one quit attempt at the end of treatment, or biochemically confirmed abstinence at 3, 6, or 12-month follow-up. Participants with LL services completed more counseling calls, accrued a longer cumulative length, and received more NRT when compared with CPO service participants. However, type of phone service did not deter abstinence outcomes. Highlights ? More calls for those with landline (LL) compared to cell only (CPO) phone access ? Cumulative treatment call time higher for those with LL compared to CPO access ? Receipt of 2nd 4-wk NRT supply more likely for those with LL compared to CPO access ? Average quitline call length was not related to LL vs. CPO phone service access. ? Abstinence 3, 6, and 12months post-baseline were similar by LL vs. CPO phone access.
