Tobacco Quit Line Re-enrollments for the Underserved

August 10, 2015 updated by: Consumer Wellness Solutions

Re-engagement in Evidence-based Quit Line Treatment for Low Income Smokers

The purpose of this proposed study is to develop, refine and test the use of Interactive Voice Response (IVR) technology as a means of increasing re-engagement of low income smokers in telephone support for tobacco cessation (quit lines). If this strategy proves to be acceptable and feasible, it may offer a technological solution to increase access to and utilization of a widely available evidence-based form of behavioral treatment for low income smokers.

The primary aims of this research are to:

  1. Develop an IVR system that delivers tailored audio messages to increase low income smokers' re-engagement in treatment offered by two state quit lines (Washington and Indiana). The investigators will develop: a) a menu of audio messages that can be delivered by an IVR system; b) an IVR algorithm (i.e., a set of decision rules) to make proactive automated calls to deliver brief, tailored messages for re-engaging low income smokers who previously used the quit line.
  2. Evaluate the feasibility and efficacy of an IVR system as a tool to re-engage low income smokers into quit line treatment measured by number of IVR calls answered, number of smokers who re-engage in treatment and satisfaction with IVR calls. Hypothesis 2.1 - It is hypothesized that the rates of re-engagement into treatment among those receiving the IVR intervention will be higher than smokers not proactively invited to re-engage in quit line services.

Detailed Description

We propose a randomized controlled trial to compare re-engagement into quit line treatment between low income smokers receiving IVR intervention to re-engage into treatment through quit line services and those receiving usual care (no intervention to re-engage). Subjects will be recruited from two state quit lines (Washington (WA) and Indiana (IN)). WA and IN were selected because they both contract with Free & Clear for quit line services and have supported research collaborations in the past. Both states have agreed to participate in this study. Three thousand subjects will be randomized to the intervention or usual care prior to entry into the IVR calling database. This sampling frame was defined based in our past research experience in using similar method to re-engage low income smokers from ethnic populations and assumed a high proportion of invalid phone numbers and difficulties on successfully reaching individuals even after several call attempts. In our previous re-engagement study, 29% of the phone numbers provided by quit line users were invalid 12 months later and 38% of the subjects were never reached after five attempted calls. Therefore, in this study we are anticipating successfully reaching 30% of the sample.

This is a feasibility study and the main outcome is re-engagement into treatment, measured by re-enrollment into quit line support after receiving the IVR intervention. Process measures are IVR calls answered and satisfaction with IVR calls. Thirty-day point prevalence abstinence at 6 months after intervention will be also measured, as a way to preliminarily evaluate the efficacy of this intervention.

The target population of this study is low income smokers, defined as being a Medicaid recipient or uninsured by the time of their first enrollment into quit line treatment. This working definition for eligibility criterion was chosen because health insurance status is routinely assessed in the provision of quit line services and it is a good proxy indicator of income.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Double

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Life Style Counseling
For individuals who report being quit, a brief congratulatory message will be delivered, independent of each arm of the study they were randomized to. For individuals who report not being quit and are randomized to the intervention condition, tailored messages are delivered via the IVR system. The automated calls would include an assessment of the individual's interest in another quit attempt and deliver brief, tailored messages to perceived barriers for re-engaging into treatment. The system is programmed to transfer the caller to a live quit line counselor if the individual is willing to re-engage in cessation treatment.
If individuals report having any smoking in the previous 30 days, the IVR will deliver questions to identify barriers to quit line re-enrollment and motivational messages to promote the re-enrollment
Active Comparator: Life Counseling
For individuals who report being quit, a brief congratulatory message will be delivered, independent of each arm of the study they were randomized to. For individuals who report still smoking the IVR will thank them for their time and the call will end.
If individuals report any smoking in the last 30 days the IVR will thank them for their time and the call will end
