State Medicaid Grant: Striving to Quit. (Status: Data under analysis for dissemination) Wisconsin received a five-year, $9.2 million grant from the federal CMS to help Medicaid recipients quit smoking. The project, called Striving to Quit, is designed to test the effects of incentives on engagement in smoking cessation treatment and quitting behavior among adult BadgerCare (Medicaid) members who smoke. It included two distinct evidence-based approaches to smoking cessation. The first focused on linking adult BadgerCare Plus members to the Wisconsin Tobacco Quit Line (WTQL), where participants received up to five proactive coaching calls (plus additional calls initiated by the participant). The second focused on linking adult BadgerCare Plus members who were pregnant with intensive cessation counseling and support via First Breath (FB), a smoking cessation program of the Wisconsin Women’s Health Foundation (WWHF), and additional postpartum services. Postpartum services included four home visits and five support phone calls up to 6 months after delivery. In each of the focus areas, WTQL and FB, half of the enrolled members received financial incentives for participating in counseling services and for quitting. The WTQL component of Striving to Quit served up to 2,000 members who smoked. Members enrolled in Striving to Quit via a referral from participating clinics in South Central and Northeastern Wisconsin. Additionally, members who resided in participant counties (Dane, Milwaukee, Racine, Kenosha, Brown, Winnebago, Portage, Marathon, Oneida, Vilas, Oconto, Forest, Fond du Lac and La Crosse) could also call the WTQL to enroll. FB enrolled approximately 1,250 pregnant members who smoked and lived in 17 counties throughout the state. This grant offered a tremendous opportunity to improve the health of thousands of Wisconsin residents with low incomes and discover whether financial incentives increase rates of smoking cessation among BadgerCare Plus members.

Can Smartphone Games Help Smokers Quit? (Status: Data under analysis for dissemination) Most smokers who try to quit do not succeed. Even if they use evidence-based treatment, only approximately 10% to 30% achieve long-term abstinence. It is known that strong craving for cigarettes is a powerful reason many smokers fail in their quit attempts. Unfortunately, medication and cessation counseling are only modestly successful in quelling craving. The objective of the research was to determine whether smartphone games can help smokers distract themselves, suppress their cravings, and increase their chances of quitting. Sept. 2013-June 2016. The $20,000 grant from a UW-CTRI Developmental Pilot Grant was part of UW-CTRI's NIH P50 Center Grant. The $6,000 grant was from a UW Department of Family Medicine Small Grant.

Advancing Tobacco Research by Integrating Systems Science and Mixture Models. This project advanced knowledge of how different smoking-cessation treatments worked, for whom, and when. Dr. Stephanie Lanza of Penn State was the lead investigator and Dr. Megan Piper, UW-CTRI associate director of research, was a co-investigator on this R01 grant from the National Cancer Institute. Researchers from The Methodology Center at Penn State integrated time-varying effect models and latent class analysis in order to identify subgroups of smokers who experienced the process of nicotine withdrawal differently. Latent class analysis allowed researchers to gauge the impact of exposure to patterns of multiple risks, as well as the antecedents and consequences of complex behaviors, so that interventions could be tailored to target the subgroups that will benefit most. Results from the project informed the construction of interventions that (1) are tailored to the individual and that (2) adapt to participant response over time. Importantly, the overall impact of this project extended far beyond the proposed analysis; the project’s full potential for accelerating the pace of smoking-cessation research was realized as a result of programmatic dissemination efforts of important new analytic methods to tobacco researchers. Sept. 2013-Aug 2015, $63,000. Funded by NCI. Dr. Stephanie Lanza, PI. Dr. Megan Piper, co-I.

Primary Care Research Fellowship. Dr. Tanya Schlam was a Primary Care Research Fellow, supported by a National Research Service Award (T32 Postdoctoral Training Grant) from the Health Resources and Services Administration to the University of Wisconsin Department of Family Medicine. July 2012-June 2015. Funded by the Health Resources and Services Administration. Dr. Bruce Barrett, PI.
