Internet-Based Smoking Cessation for Operations Enduring Freedom and Iraqi Freedom (OEF/OIF) Veterans

2014-07-23 21:12:18 | BioPortfolio


The overarching aim of the study is to evaluate in a randomized trial the impact of an internet intervention compared to a standard clinic-based control group to promote smoking cessation among Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF) veterans.


Project Background: Veterans returning from Iraq and Afghanistan are smoking at high rates and are at elevated risk for the development of smoking related illness. Intensive speciality clinic-based tobacco cessation programs have high efficacy, are more cost effective than less intensive approaches, and are employed by most VA medical centers. These programs, however, are infrequently attended by veterans, limiting the impact on prevalence, disease burden, and economic costs of smoking. An internet-based smoking cessation intervention could be an effective, low-cost method to implement evidence based smoking cessation principles. The internet could significantly increase the impact of smoking cessation efforts over current approaches by avoiding barriers that limit utilization of existing clinic-based services.

Project Objectives: The goal of the study is to evaluate the impact of an internet-based intervention in comparison to standard VA speciality clinic-based care in promoting smoking cessation in returning veterans. Accordingly, the specific aims and hypotheses are:

AIM 1: To evaluate the impact of an internet-based smoking cessation intervention on rates of abstinence from cigarettes (self-reported 7-day point prevalent abstinence) at 3 months and 12-month post-treatment follow-ups.

Hypothesis 1: Abstinence rates will be significantly higher among veterans randomized to the web-based intervention than those randomized to VA specialty cessation care.

AIM 2: To evaluate the impact of an internet-based smoking cessation intervention on reach of smoking cessation treatment.

Hypothesis 2.1: Internet-based treatment will result in increased reach as measured by the proportion of patients who access care. Hypothesis 2.2: Internet-based treatment will result in engagement in treatment as measured by the proportion of patients that make at least one quit attempt.

AIM 3: To evaluate the relative cost-effectiveness of the standard specialty care intervention to the web-based intervention.

Project Methods: Proposed is a trial in which 410 OEF/OIF veteran smokers will be randomized to receive either an internet-based smoking cessation intervention and nicotine replacement therapy or referral to VA specialty smoking cessation care, which includes behavioral therapy, group counseling, telephone counseling, self-help materials, and choice of smoking cessation aid (pharmacotherapy).

Participating patients will be surveyed at 3 months post-intervention and at 12 months. The primary outcome of the trial is a 7-day point prevalence abstinence at the 3-month post intervention follow-up, as measured by self-report and verified by cotinine assay.

Medical and Biotech [MESH] Definitions

A decrease in the incidence and frequency of SMOKING. Smoking reduction differs from SMOKING CESSATION in that the smoker continues to smoke albeit at a lesser frequency without quitting.

An approach, process, or methodology which emphasizes credible evidence and the best available scientific knowledge, judiciously integrated to achieve the best possible outcomes in structural design. For example, the design of a new OUTPATIENT CLINIC might incorporate a review of published research on outpatient clinic design, decisions on similar past projects, along with interviews with staff and consumers.
