“…36 Staff contacted proxies to verify abstinence among participants who did not provide cotinine or CO. At the time of study implementation, proxy verification was considered a valid method for confirming abstinence. 37–39 A recent analysis of proxy verification in a clinical trial suggests it is no more valid than self-report. 40 To examine the impact of proxy verification, the proportions of patients who verified abstinence via cotinine, CO, and proxy are reported.…”

Introduction Few hospitals treat patients’ tobacco dependence. To be effective, hospital-initiated cessation interventions must provide at least 1 month of supportive contact post-discharge. Study design Individually randomized clinical trial. Recruitment commenced July 2011; analyses were conducted October 2014–June 2015. Setting/participants The study was conducted in two large Midwestern hospitals. Participants included smokers who were aged ≥18 years, planned to stay quit after discharge, and spoke English or Spanish. Intervention Hospital-based cessation counselors delivered the intervention. For patients randomized to warm handoff, staff immediately called the quitline from the bedside and handed the phone to participants for enrollment and counseling. Participants randomized to fax were referred on the day of hospital discharge. Main outcome measures Outcomes at 6 months included quitline enrollment/adherence, medication use, biochemically verified cessation, and cost effectiveness. Results Significantly more warm handoff than fax participants enrolled in quitline (99.6% vs 59.6%; relative risk, 1.67; 95% CI=1.65, 1.68). One in four (25.4% warm handoff, 25.3% fax) were verified to be abstinent at 6-month follow-up; this did not differ significantly between groups (relative risk, 1.02; 95% CI=0.82, 1.24). Cessation medication use in the hospital and receipt of a prescription for medication at discharge did not differ between groups; however, significantly more fax participants reported using cessation medication post-discharge (32% vs 25%, p=0.01). The average incremental cost-effectiveness ratio of enrolling participants into warm handoff was $0.14. Hospital-borne costs were significantly lower in warm handoff than in fax ($5.77 vs $9.41, p<0.001). Conclusions One in four inpatient smokers referred to quitline by either method were abstinent at 6 months post-discharge. Among motivated smokers, fax referral and warm handoff are efficient and comparatively effective ways to link smokers with evidence-based care. For hospitals, warm handoff is a less expensive and more effective method for enrolling smokers in quitline services.

“…[27] We also conducted validation via proxy report from a significant other among quitters who did not return a salivary sample. [28] Secondary outcomes at 3, 6, and 12 months included self reported point prevalence abstinence; frequency and duration of quit attempts; average number of cigarettes smoked per day; and prolonged abstinence. Prolonged abstinence as defined in this study included a “grace period” of 1-month at the beginning of treatment to allow the treatment to take effect (i.e.…”

Introduction In rural America cigarette smoking is prevalent, few cessation services are available, and healthcare providers lack the time and resources to help smokers quit. This paper describes the design and participant characteristics of Connect2Quit (C2Q), a randomized control trial (RCT) that tests the effectiveness and cost-effectiveness of integrated telemedicine counseling delivered by 2-way webcams mounted on desktop computers in participant's physician office examining rooms (ITM) versus quitline counseling delivered by telephone in participant's homes (Phone) for helping rural smokers quit. Methods/Design C2Q was implemented in twenty primary care and safety net clinics. Integrated Telemedicine consisted of real-time video counseling, delivered to patients in their primary care physician's (PCP) office. Phone counseling, was delivered to patients in their homes. All participants received educational materials and guidance in selecting cessation medications. Results The 566 participants were predominantly Caucasian (92%); 9% were Latino. Most (65%) earned < 200% of federal poverty level. One out of three lacked home internet access, 40% were not comfortable using computers, and only 4% had been seen by a doctor via telemedicine in the past. Hypertension, chronic lung disease, and diabetes were highly prevalent. Participants smoked nearly a pack a day and were highly motivated to quit. Discussion C2Q is reaching a rural low-income population, with comorbid chronic diseases, that would benefit greatly from quitting smoking. ITM is a good delivery model, which integrates care by holding counseling sessions in the patient's PCP office and keeps the primary care team updated on patients’ progress.

“…Validation studies of this method have shown proxies to be accurate when evaluated against self-report. 7,8 The success of proxy informants in surveillance research has prompted the use of proxy verification to corroborate self-report in a few studies of smoking cessation interventions. [9][10][11] However, there are important differences between the two types of studies that may render proxy informants less accurate in cessation research.…”

Introduction: Biochemical confirmation (BC) of self-report is the gold standard of evidence for abstinence in smoking cessation research, but difficulty in obtaining samples may bias estimates of quit rates. Proxy confirmation (PC) has not been validated in cessation trials. We assessed the feasibility and validity of PC in a cessation trial for hospitalized smokers. Methods: We enrolled 402 daily cigarette smokers during a hospital admission. At enrollment, participants provided demographics, smoking history, and named proxies to confirm their smoking status at follow-up. Participants provided self-reported (SR) 7-day tobacco abstinence by telephone at 6 months post-discharge. SR quitters were asked to mail a saliva sample for BC. Incentives were offered for survey completion ($20) and returned samples ($50). We called proxies for all those with SR to obtain PC. Quit rates were calculated with missing data indicating smoking. We assessed associations of nonresponse with baseline characteristics using chi-squared tests and logistic regression. We calculated the sensitivity and specificity of PC in detecting smokers as determined by BC. Results: All patients named at least one proxy. Response rates were 82% for SR, 84% for PC, and 69% for BC. Observed participant characteristics were unrelated to provision of sample for BC. Estimated quit rates were 35% for SR, 27% for SR + PC, 21% for SR + BC and 27% for SR + BC or PC. Sensitivity of PC was not higher than SR (73% vs. 77%); specificity was lower (84% vs. 100%). Conclusion: PC was feasible but not superior to self-report in a cessation trial.
