Pilot trial of nicotine replacement therapy sampling in a dental care clinic

Abstract

Nicotine replacement therapy sampling (NRTS) refers to providing all smokers, regardless of interest in quitting, with free samples of over-the-counter NRT. NRTS has been shown to increase quit attempts and abstinence.We conducted a pilot trial with a goal to establish the feasibility and acceptability of NRTS in a dental clinic, where providing free samples is routine and universal.Participants (N = 30) completed a baseline survey and were randomized to receive or not receive a 2-week supply of NRT samples (14 mg patches and 4 mg lozenges) in a 3:1 ratio.We enrolled 30 of 50 potentially eligible patients, of whom 26 completed a 4-week follow-up survey. At follow-up, 61% of the NRT group reported use of the samples and 26% said they used more NRT obtained on their own. In the No NRT group, only one patient reported using NRT. No patients reported past week abstinence, but 43% of the NRT group vs. 29% of the No NRT group reported making a quit attempt lasting longer than 24 h.The pattern of results suggests that conducting a larger trial would be feasible and that the NRTS intervention was acceptable to dental patients.
