Title: Smoking Cessation Following Text Message Intervention in Pregnant Women
Brief Summary: The investigators propose an 18-month, randomized, open-label evaluation of the impact of texting to pregnant, underserved, cigarette smokers on smoking cessation rates. Patients will be eligible if they have a confirmed pregnancy, are English speaking, at least 18 years of age, are in the preparation stage of change and willing to set a quit date within 30 days and before 35 weeks gestation, and have a cellular phone that is capable of receiving text messages. Patients will be randomized to either the texting group or control group. A baseline carbon monoxide level will be obtained. The patient, regardless of group, will have the standard of care smoking cessation visit. If the pharmacist, physician, and patient deem that pharmacotherapy is appropriate, patient will receive nicotine replacement therapy patches or bupropion free of charge in 2-week intervals. Patients in the intervention group will receive text messages focused on smoking cessation and pregnancy. Patients will be seen on a bi-weekly schedule to obtain additional vouchers for patches or for bupropion, meet with the pharmacist, and complete a carbon monoxide exhalation test. These visits will be continued until the pharmacotherapy course is complete.
