Study information

Scientific title

Enhancing Oral Health Professionals' competencies in Tobacco Use Prevention and Cessation: A randomised controlled community-based trial



Study hypothesis

The main hypothesis is that an educational training intervention that includes information on
1. tobacco use and oral health
2. tobacco dependence as a chronic condition
3. treatment options for tobacco dependence
4. the practice guideline "Treating Tobacco Use and Dependence"
will reduce the barriers and facilitate the delivery of tobacco dependence counselling and treatment by oral health professionals to their patients if the administration of health centres enables and motivates them to do so.

Ethics approval

1. Ethical Committee of Tampere Hospital District approved on the 7th of November 2009 (ref: R08108)
2. Ethical Committee of Vaasa Hospital District approved on the 14th of October 2009 (ref: 9/2008)

We compare the effects of two interventions on the implementation of the Clinical Practice Guideline "Treating Tobacco Use and Dependence" among dental practitioners. Dental clinics participating in this study will be primary care dental centres in the cities of Vaasa and Tampere, Finland. All dental clinics in Vaasa (about 12 clinics) and Tampere (about 34 clinics) health centres will participate with no exceptions. Dental clinics will be randomly assigned to one of three groups, so that the three groups have an equivalent number of clinics assigned. Before intervention, principles of documenting patientsÂ’ tobacco use into medical records are instructed to all clinics. The intervention components to be tested are as follows:
Group A: Controls (Routine Care)
Group B: Educational Intervention
Group C: Educational Intervention + Monetary incentives

The educational intervention was exactly the same for both groups B and C. The total duration of the educational intervention was seven hours administered during one day from 8:00 a.m. to 3:00 p.m. Five hours of intensive training, included lectures, Q&A sessions, multi-media demonstrations, and a role play session with standard patient cases where the students were working in smaller groups. During the coffee and lunch breaks the students had an opportunity to study a selection of self-help materials and nicotine replacement therapy options in treatment of tobacco dependence. Study material included a binder with hand-outs of each teaching session as well as of the patient cases and a wide range of internet based sources of relevant information with the links for each site provided. All these materials were entered also to the project web site to be accessible in electronic format later on for participants of the educational intervention (username and password given).
Teaching modules included
1. Epidemiology of tobacco use and its health consequences
2. Role of oral health professionals in prevention and cessation of tobacco use
3. Tobacco dependence
4. Pharmacological treatment of tobacco dependence
5. Non-pharmacological treatment of tobacco dependence
6. How to implement the 6Ks in oral health practice (Finnish modification of the 5 As Clinical Practice Guideline "Treating Tobacco Use and Dependence")
7. Youth and tobacco
8. Resources and self help materials
9. Standard patient cases session. It took place in three groups (being mentored by one of the teachers plus one assistant). There were six standard patient cases (2 female/ 4 male; 2 adolescent/4 adult; 4 cigarette smokers/2smokeless tobacco users) played out by professional actors and/or students. There was a written protocol and time schedule to follow in each group to ensure that each participant of the educational intervention had an opportunity to practice tobacco dependence counseling at least once and that all patient cases could be practiced in every group. After the small group sessions, all the participants were invited back to the lecture setting where the teachers gave feed-back for possible solutions for each patient case treatment and counseling.
