Longitudinal Electronic Cigarette Use Among Patients Recently Diagnosed With Cancer Enrolled in a Smoking Cessation Trial.

INTRODUCTION: Many cancer patients who smoke report concurrent e-cigarette use. Using a mixed-methods approach, we aimed to (1) describe longitudinal e-cigarette use over 6 months after a cancer diagnosis and (2) assess the association between e-cigarette use and smoking cessation, among cancer patients in a smoking cessation trial. AIMS AND METHODS: Data were from a 2-site randomized controlled trial of Standard (brief counseling) versus Intensive treatment (sustained counseling plus smoking cessation medication) in individuals who smoke recently diagnosed with cancer. Participants (n = 303) reported e-cigarette use at baseline, 3 months, and 6 months. Biochemically-verified past 7-day cigarette abstinence was collected at 6 months. Qualitative interviews at 6 months explored factors related to e-cigarette use. RESULTS: E-cigarette use prevalence was highest between baseline and 3 months (16%) and declined over time. Participants using e-cigarettes at follow-up had higher baseline cigarette dependence and smoked more heavily. Multivariable analyses found no significant association between follow-up e-cigarette use and 6-month cigarette abstinence. E-cigarette use at follow-up was higher in the Standard versus Intensive treatment group (p = .003 and .001 at 3 and 6 mo, respectively). Smoking cessation and health concerns were primary reasons for using e-cigarettes. CONCLUSIONS: Among individuals who smoke recently diagnosed with cancer and enrolled in a smoking cessation intervention trial, e-cigarette use during trial participation was not associated with smoking abstinence. Individuals who chose to use e-cigarettes were less likely to be receiving intensive cessation support as part of the trial. Further studies are needed to evaluate the association between e-cigarette use and smoking cessation in cancer patients. IMPLICATIONS: E-cigarette use was not associated with cigarette abstinence at 6 months among adults who smoke recently diagnosed with cancer enrolled in a smoking cessation trial. Individuals with easier access to evidence-based smoking cessation treatment may be less likely to use e-cigarettes.

Investigating documentation of alcohol and non-medical substance use in oncology treatment: an electronic health record review.

PURPOSE: Little is known about non-tobacco substance use (SU) and its treatment in cancer patients. National guidelines address tobacco only, and assessment of SU in cancer patients is not standardized. It is not clear how oncology clinicians assess, document, and follow-up on SU. METHODS: We conducted an electronic health record review of patients enrolled in a smoking cessation trial at one large hospital site (N = 176). Chart review of oncology treatment notes assessed whether SU assessment was documented, the content of the documentation/assessment (e.g., frequency of use), and details about documentation (e.g., where/who documented). RESULTS: Sixty-nine percent (121/176) of cancer patients had SU documented. Many patients (42%, 74/176) had only one substance documented; 66% (116/176) had alcohol use documented. For a substantial minority of patients (43/176; 24%), the provider did not specify the substance assessed (e.g., "drug use," "illicits"). SU was primarily documented by physicians (84%, 102/121), in routine progress notes (56%, 68/121), in the "social history" section of the note (84%, 102/121). Only 4 patients had a documented SU follow-up plan. When examining the subset of patients who reported problematic alcohol use (N = 27), the content of documentation was inconsistent (e.g., number of drinks/day vs. qualitative descriptors of use). CONCLUSIONS: About 1/3 of oncology patients did not have SU assessment documented. SU other than alcohol use was infrequently documented, many clinicians documented SU but did not specify substance type, and few clinicians documented a follow-up plan for problematic SU. Oncology settings should utilize standardized assessment and referral for SU treatment.

Examining the effects of stress and psychological distress on smoking abstinence in cancer patients.

INTRODUCTION: Cancer patients who smoke report more stress and psychological distress than patients who do not smoke. It is unclear how these emotional symptoms may modify smoking behavior in cancer patients. We examined the influence of a smoking cessation intervention for cancer patients on stress and distress, and the effects of these symptoms on smoking abstinence. METHODS: Mixed-methods secondary analysis of data from the Smokefree Support Study, a two-site randomized controlled trial examining the efficacy of Intensive (IT; n = 153) vs. Standard Treatment (ST; n = 150) for smoking cessation in newly diagnosed cancer patients. Stress coping, perceived stress, distress, and anxiety were self-reported at baseline, 3, and 6 months. Abstinence was biochemically-confirmed at 6 months. A subset of patients (n = 72) completed qualitative exit-interviews. RESULTS: Patients were on average, 58 years old, 56% female, and smoked a median of 10 cigarettes/day. There were no significant treatment group × time interactions or main effects of treatment group on stress or distress measures (p's > 0.05), however there were significant main effects of time suggesting symptom improvements on each measure in both study groups (p's < 0.05). In adjusted logistic regression models, lower levels anxiety at 3 months predicted confirmed smoking abstinence at 6 months (p = .03). Qualitatively, at 6 months, patients reported their stress and smoking were connected and that the cessation counseling was helpful. CONCLUSIONS: Cancer patients enrolled in a smoking cessation trial report decreases in stress, distress and anxiety over time, and anxiety symptoms may impact smoking cessation success at follow-up resulting in an important intervention target.

Examining the effects of problematic alcohol use on cigarette abstinence in recently diagnosed cancer patients enrolled in a cessation trial: A secondary analysis.

AIMS: Among people with cancer, dual alcohol and tobacco use increases risk for morbidity and mortality. Most smoking cessation clinical trials with this patient population have excluded individuals with problematic alcohol use. This investigation examined whether problematic alcohol use affects smoking cessation in cancer patients. METHODS: Mixed-methods secondary analysis of data from the Smokefree Support Study, a randomized-controlled trial examining the efficacy of Intensive (IT; n = 153) vs. Standard Treatment (ST; n = 150) for smoking cessation in newly diagnosed cancer patients. Problematic alcohol use was assessed at enrollment using the Cut-Down-Annoyed-Guilty-Eye-Opener (CAGE), weekly frequency of alcohol use and binge drinking measures. Alcohol use was categorized as: no current alcohol use, moderate and problematic use. The primary outcome was biochemically-confirmed cigarette abstinence at 6-months. A subset of patients (n = 72) completed qualitative exit-interviews. RESULTS: Among all participants, biochemically-confirmed cigarette abstinence rates were 25% (n = 32), 28% (n = 27), and 36% (n = 20) for participants reporting no current alcohol use, moderate use, and problematic use, respectively (p = 0.33). In logistic regression analysis, neither problematic alcohol use (AOR = 0.96, 95% CI = 0.35-2.67, p = .94) nor the problematic use by study arm interaction (AOR = 2.22, 95% CI = 0.59-8.39, p = .24) were associated with biochemically-confirmed 6-month abstinence. Qualitatively, participants reported that drinking alcohol triggers urges to smoke. CONCLUSION: Newly diagnosed cancer patients reporting problematic alcohol use were not less likely to quit smoking than those without. Additional research is needed to investigate whether problematic alcohol users may benefit from smoking and alcohol behavior change interventions at the time of cancer diagnosis.
