ABSTRACT The dental visit is a unique opportunity for tobacco control. Despite evidence of effectiveness in dental settings, brief provider-delivered cessation advice is underutilized.
To evaluate an Internet-delivered intervention designed to increase implementation of brief provider advice for tobacco cessation in dental practice settings.
Dental practices (N = 190) were randomized to the intervention website or wait-list control. Pre-intervention and after 8 months of follow-up, each practice distributed exit cards (brief patient surveys assessing provider performance, completed immediately after the dental visit) to 100 patients. Based on these exit cards, we assessed: whether patients were asked about tobacco use (ASK) and, among tobacco users, whether they were advised to quit tobacco (ADVISE). All intervention practices with follow-up exit card data were analyzed as randomized regardless of whether they participated in the Internet-delivered intervention.
Of the 190 practices randomized, 143 (75%) dental practices provided follow-up data. Intervention practices' mean performance improved post-intervention by 4% on ASK (29% baseline, adjusted odds ratio = 1.29 [95% CI 1.17-1.42]), and by 11% on ADVISE (44% baseline, OR = 1.55 [95% CI 1.28-1.87]). Control practices improved by 3% on ASK (Adj. OR 1.18 [95% CI 1.07-1.29]) and did not significantly improve in ADVISE. A significant group-by-time interaction effect indicated that intervention practices improved more over the study period than control practices for ADVISE (P = 0.042) but not for ASK.
This low-intensity, easily disseminated intervention was successful in improving provider performance on advice to quit. NCT00627185,

    ABSTRACT: Pharmacists are uniquely positioned within the community to provide smoking cessation counseling to their patients. However, pharmacists experience significant barriers to providing counseling, including limited time, reimbursement, and training in counseling techniques. We tested a computer-driven software system, "Exper_Quit" (EQ), that provided individually tailored interventions to patients who smoke and matching tailored reports for pharmacists to help guide cessation counseling. A two-phase design was used to recruit an observation-only group (OBS; n = 100), followed by participants (n = 200) randomly assigned to receive either EQ-assisted pharmacist counseling or EQ plus 8 weeks of nicotine transdermal patch (EQ+). Both treatment groups were scheduled to receive two follow-up counseling calls from pharmacists. Most participants in the EQ and EQ+ groups reported receiving counseling from a pharmacist, including follow-up calls, while none of the OBS participants reported speaking with the pharmacist about cessation. At 6 months, fewer OBS participants reported a quit attempt (42%) compared with EQ (76%) or EQ+ (65%) participants (p < .02). At 6 months, 7-day point-prevalence abstinence was 28% and 15% among the EQ+ and EQ groups, respectively, compared with 8% among OBS participants (p < .01), and EQ+ participants were twice as likely to be quit than were EQ participants (p < .01). A tailored software system can facilitate the delivery of smoking cessation counseling to pharmacy patients. Results suggest that EQ was successful in increasing (a) the delivery of cessation counseling, (b) quit attempts, and (c) quit rates. Pharmacists can play an important role in the effective delivery of smoking cessation counseling.

    ABSTRACT: To contribute towards reversing the tobacco pandemic, professional organisational alliances must reduce the wide international variability in the smoking rates among health-care professionals and students, and also address the gaps in tobacco cessation training and services. Ongoing international surveys for monitoring smoking rates could provide the impetus for these alliances to develop programs that reduce smoking rates among professional and lay populations. Health professional organisations must advocate for systematically implementing comprehensive tobacco cessation training programs. These programs can include both evidence-based interventions and experience-based learning innovations. These innovations can help individuals address the limitations of evidence-based guidelines. This shift from teaching individuals about changing-specific risk behaviours to engaging individuals to learn how to change any risk behaviour expands the reach and impact of behaviour change programs. Practitioners and staff need first-hand experience of these learning innovations before guiding patients through the same process. Using both evidence-based guidelines and experience-based learning methods, organisational leaders can develop professional alliances to create social movements that promote healthy habits in general. For example, they can develop voluntary learning programs in primary care and community settings that are led by patients and that are for patients. Such bottom-up approaches have greater potential yield in addressing gaps in health promotion and disease prevention, and particularly for tobacco cessation services. This strategy is a more feasible option for resource-limited, developing countries that cannot afford costly tobacco cessation programs.

    ABSTRACT: The Internet has become a regular part of daily life for the majority of people in many parts of the world. It now offers an additional means of effecting changes to behaviour such as smoking. To determine the effectiveness of Internet-based interventions for smoking cessation. We searched the Cochrane Tobacco Addiction Group Specialized Register, with additional searches of MEDLINE, EMBASE, CINAHL, PsycINFO, and Google Scholar. There were no restrictions placed on language of publication or publication date. The most recent search was in June 2010. We included randomized and quasi-randomized trials. Participants were people who smoked, with no exclusions based on age, gender, ethnicity, language or health status. Any type of Internet-based intervention was eligible. The comparison condition could be a no-intervention control or a different Internet site or programme. Methodological and study quality details were extracted using a standardised form. We selected smoking cessation outcomes at short term (one to three months) and long term (6 months or more) follow up, and reported study effects as a risk ratio with 95% confidence intervals. Only limited meta-analysis was performed, as the heterogeneity of the data for populations, interventions and outcomes allowed for very little pooling. Twenty trials met the inclusion criteria. There were more female than male participants. Some Internet programmes were intensive and included multiple outreach contacts with participants, whilst others relied on participants to initiate and maintain use.Ten trials compared an Internet intervention to a non-Internet based smoking cessation intervention or to a no intervention control. Six of these recruited adults, one recruited young adult university students and three recruited adolescents. Two trials of the same intensive automated intervention in populations of adult who smoked showed significantly increased cessation compared to printed self-help materials at 12 months. In one of these, all trial participants were provided with nicotine replacement therapy (NRT). Three other trials in adults did not detect significant long term effects. One of these provided access to a website as an adjunct to counselling and bupropion, one compared web-based counselling, proactive telephone-based counselling or a combination of the two as an adjunct to varenicline. The third only provided a list of Internet resources. One further short-term trial did show a significant increase in quit rates at 3 months. A trial in college students increased point prevalence abstinence after 30 weeks but had no effect on sustained abstinence. Two small trials in adolescents did not detect an effect on cessation compared to control, whilst a third small trial did detect a benefit of a web-based adjunct to a group programme amongst adolescents.Ten trials, all in adult populations, compared different Internet sites or programmes. There was some evidence that sites that were tailored and interactive might be more effective than static sites, but this was not detected in all the trials that explored this factor. One large trial did not detect differences between different Internet sites. One trial of a tailored intervention as an adjunct to NRT use showed a significant benefit but only had a 3-month follow up. One trial detected evidence of a benefit from tailored email letter compared to a non-tailored one. Trials failed to detect a benefit of including a mood management component (three trials), or an asynchronous bulletin board. Higher abstinence rates were typically reported by participants who actively engaged with the programme (as reflected by the number of log-ins). Results suggest that some Internet-based interventions can assist smoking cessation, especially if the information is appropriately tailored to the users and frequent automated contacts with the users are ensured, however trials did not show consistent effects.
