Tobacco cessation in dental settings: research findings and future directions

A randomised controlled trial of a smoking cessation intervention delivered by dental hygienists: a feasibility study

BACKGROUND

Tobacco use continues to be a global public health problem. Helping patients to quit is part of the preventive role of all health professionals. There is now increasing interest in the role that the dental team can play in helping their patients to quit smoking. The aim of this study was to determine the feasibility of undertaking a randomised controlled smoking cessation intervention, utilising dental hygienists to deliver tobacco cessation advice to a cohort of periodontal patients.

METHODS

One hundred and eighteen patients who attended consultant clinics in an outpatient dental hospital department (Periodontology) were recruited into a trial. Data were available for 116 participants, 59 intervention and 57 control, and were analysed on an intention-to-treat basis. The intervention group received smoking cessation advice based on the 5As (ask, advise, assess, assist, arrange follow-up) and were offered nicotine replacement therapy (NRT), whereas the control group received 'usual care'. Outcome measures included self-reported smoking cessation, verified by salivary cotinine measurement and CO measurements. Self-reported measures in those trial participants who did not quit included number and length of quit attempts and reduction in smoking.

RESULTS

At 3 months, 9/59 (15%) of the intervention group had quit compared to 5/57 (9%) of the controls. At 6 months, 6/59 (10%) of the intervention group quit compared to 3/57 (5%) of the controls. At one year, there were 4/59 (7%) intervention quitters, compared to 2/59 (4%) control quitters. In participants who described themselves as smokers, at 3 and 6 months, a statistically higher percentage of intervention participants reported that they had had a quit attempt of at least one week in the preceding 3 months (37% and 47%, for the intervention group respectively, compared with 18% and 16% for the control group).

CONCLUSION

This study has shown the potential that trained dental hygienists could have in delivering smoking cessation advice. While success may be modest, public health gain would indicate that the dental team should participate in this activity. However, to add to the knowledge-base, a multi-centred randomised controlled trial, utilising biochemical verification would be required to be undertaken.

Tobacco use quitline enrollment through dental practices

BACKGROUND

Time and resource constraints limit the ability of oral health care professionals to help patients quit smoking. Opportunities exist for dental providers to help patients who smoke by enrolling them in tobacco use quitlines. The authors conducted a pilot study to investigate whether such referrals were feasible and effective.

METHODS

The authors randomly assigned eight general dental practices to provide either brief counseling regarding smoking cessation or brief counseling along with referrals to a tobacco use quitline for patients receiving routine dental hygiene care who reported that they were currently smoking cigarettes.

RESULTS

The authors enrolled 82 patients (60 in the tobacco use quitline group, 22 in the brief counseling group). At six months, the self-reported, seven-day point prevalence tobacco use abstinence rates were 25.0 percent (15 of 60 patients) in the tobacco use quitline group and 27.3 percent (six of 22 patients) in the brief-counseling group (P approximately 1.0). Twenty-eight (47 percent) of 60 subjects in the tobacco use quitline group completed the initial tobacco use quitline consultation. Abstinence rates among subjects in the quitline group were higher if they completed more telephone consultations.

CONCLUSIONS

Referral to a tobacco use quitline by dental practices is a feasible strategy for helping patients quit smoking if efficient links between the dental practice and the tobacco use quitline can be established. Research is needed to evaluate whether it is more effective than standard clinical interventions for tobacco use cessation.

CLINICAL IMPLICATIONS

Dental practitioners with limited time and other resources can assist patients who smoke by referring them to a tobacco use quitline.

A web-based smoking cessation and prevention curriculum for medical students: why, how, what, and what next

This paper summarises some major developments in medical education relating to the health risks of tobacco and to training in tobacco cessation and prevention strategies, and discusses some of the barriers to training. We also describe a project whose purpose was to design, implement and evaluate a web-based self-study tobacco curriculum for medical students to teach medical students to assist smokers to quit and to counsel non-smoking adolescents not to start smoking. This curriculum addresses some of the barriers, namely lack of curriculum time, lack of access to materials and experts, and relevance of the materials. The project was designed and evaluated at two medical schools in Georgia: Morehouse School of Medicine and Mercer University School of Medicine. A curriculum on tobacco control strategies and techniques designed for use in clinical settings was made available to first-year medical students as interactive computer-based tutorials. The curriculum, based on the US Public Health Service Clinical Guideline for Treating Tobacco Use and Dependence, was divided into two parts: the tutorial and practicum sections. Pre- and post-exposure measures were collected for the evaluation. The mean differences for correctly answered knowledge items in the two schools were similar: mean for Morehouse was +2.07 and for Mercer +1.67, indicating improvements in knowledge for both schools. There were statistically significant improvements in all categories of self-rated ability to perform six counselling skills, except for Mercer students for the 'Ask' skill category (p=0.069). The amount of exposure (measured only at Morehouse) was not related to overall change in scores but was associated with self-reported improvement in skill in assisting patients to quit smoking, confidence in counselling patients not interested in quitting, and confidence in counselling teens. The web-based curriculum successfully improved the students' self-rated counselling skills. Given the need and desire on the part of practitioners for training, the curriculum may be found useful by practising physicians and other health-care professionals who wish to improve their skills in smoking prevention and cessation.
