Role of procedural intervention and acute illness in veterans affairs smoking cessation program referrals: A retrospective study

INTRODUCTION: Tobacco use remains pervasive amongst veterans. Unfortunately, the negative impact on postoperative outcomes may preclude surgeons from offering operative intervention to veterans who smoke. As such, a major health event may provide added incentive to quit. We sought to describe the role of acute illness and interventional specialist involvement in Veterans Affairs Smoking Cessation Program referrals compared to primary care wellness initiatives. METHODS: We retrospectively reviewed consultations to the pharmacy-led Smoking Cessation Program (SCP) at the Middleton Memorial VA Hospital from 2017 to 2019. Consultations placed during the last three months were categorized based on the source of referral: primary care, acute care, and interventional specialties. Descriptive statistics were used to assess rates of veteran engagement based on referral source. Consultation completion was used as a proxy for veteran engagement. RESULTS: A total of 2993 new SCP consultations were placed during the study period. Overall, veteran engagement rose from 43% in 2017 to 53% in 2019. In recent months, there were 282 SCP referrals. While only 19 (7%) of these referrals were placed by interventional specialties – primarily cardiology and thoracic surgery – the rate of veteran engagement was 63%. The majority of referrals (65%) were placed by primary care providers with an engagement rate of 68%. In contrast, only 42% of consultations placed in the context of an acute illness were completed. CONCLUSIONS: In our study, primary care directed smoking cessation referrals were most prevalent and resulted in the highest completion rates. The presence of an acute illness in isolation failed to impact program success. However, while surgeon-initiated referrals were meager in number, the engagement rate approached that of primary care. This finding suggests that surgeons play a powerful role in influencing patient behavior that may be harnessed to augment success of existing smoking cessation programs.
