Pilot Test of Connecting Pregnant Women who Smoke to Short Message Service (SMS) Support Texts for Cessation

Most pregnant women know that smoking poses serious risks to baby and mother, yet many still smoke. We conducted a large randomized controlled trial and found that an SMS text-delivered program helped about 10% of these women quit smoking. In this paper, we describe the feasibility of disseminating a text-based intervention to pregnant women who smoke. We tested dissemination in two ways from prenatal clinics and compared recruitment rates to those found in our large randomized controlled trial. The first method involved “direct texting” where study staff identified women who smoked and sent them a text asking them to text back if they wanted to receive texts to help them quit. The second involved “nurse screening” where clinic staff from county health departments screened women for smoking and asked them to send a text to the system if they wanted to learn more about the program. Our primary outcome was feasibility assessed by the number of women who texted back their baby’s due date, which served as “enrolling” in the texting program, which we compared to the recruitment rate we found in our large trial. Over 4 months, we texted 91 women from the academic health system. Of those, 17 texted back and were counted as “enrolled.” In the health departments, across the 4 months, 12 women texted the system initially. Of those, 10 were enrolled. This rate was similar to the rate enrolled in the randomized controlled trial. Two different methods connected pregnant women who smoke to a texting program. One of these methods can be automated further and have the potential of helping many women quit smoking with minimal effort. Clinical Trial # NCT01995097
