Plain English Summary

Background and study aims
Stopping smoking can be very difficult for some people, and many people wanting to quit smoking might need a lot of advice and encouragement. Primary health care (PHC) providers, such as GPs, are one of the main points of contact for people wanting to quit smoking. GPs can help by providing advice ranging from available nicotine replacement therapies (gum, patches, e-cigarettes) to putting people in touch with group support programmes. The TiTAN Project is a programme dedicated to developing a PHC tobacco dependence treatment (TDT) network in Crete, Greece. TiTAN aims to provide PHCs with additional tools and training that they can use to help their patients successfully quit smoking. The aim of this study is to see how successful GP practices participating in the TiTAN programme are in helping their patients quit smoking, compared to GP practices providing standard stop-smoking advice. This study will also see how successful participating GP practices are at promoting the programme’s values and providing patients with the best stop-smoking tools.

Who can participate?
Adult smokers attached to participating GP practices.

What does the study involve?
Participating GP practices are allocated into one of two groups. Those in group 1 (intervention group) are GP practices attached to the University of Crete research network. Group 1 GP practices adopt the TiTAN-Crete Global Bridges programme, and use their training to encourage and inform smokers attached to their practice about stopping smoking. A cross-section of smokers attached to group 1 GP practices is surveyed before the programme starts; a different cross-section of smokers is surveyed 2-4 months after the start of the programme. Those in group 2 (control group) are GP practices from the city of Rethymno, Crete. Group 2 GP practices provide smokers attached to their practices with standard treatment for stopping smoking. A cross-section of smokers attached to group 2 GP practices is surveyed before the programme starts. Surveys are completed by all participating GP practices at the start of the study, then again 4 months later.

What are the possible benefits and risks of participating?
There are no direct risks or benefits to participants.

Primary care tobacco treatment training network in Crete: a before and after study



Study hypothesis

The intervention program will increase primary care providers':
1. Attitudes, beliefs, perceived behavioural control and intentions towards the delivery of evidence-based smoking cessation treatments compared to control practices
2. Rates at which they deliver evidence-based smoking cessation treatments to smokers compared to control practices

Smoking cessation


The intervention program involves key opinion leaders, training, office support tools and coaching. The program has a core session which is followed up by 4 shorter booster sessions. Booster sessions are given over a 2-4 month period following the initial core session:
1. Core session content is composed of 2/3 theory and 1/3 practical (on the job). Core content includes: the burden of tobacco control in Greece, evidence-based tobacco treatment practices in primary care, first-line pharmacotherapies, behavioural counselling techniques for use in busy clinical settings, strategies for intervening with patients ready and not ready to quit smoking, special populations, setting up your practice for success, your role as clinician-advocate in tobacco control. Special emphasis will be placed upon training the primary health care (PHC) providers in overall tobacco control so that they develop the knowledge to act as policy advocates at a regional and national level. The program will employ teaching techniques such as role-play and case study approaches known to enhance up-take into practice.
2. Booster sessions are designed to reinforce the adoption of new practice behaviours and offer skill-based training, including case-based training focused on patients within a provider’s own practice. Local faculty (opinion leaders) as well as international Global Bridges faculty will deliver program training and tailor its content to meet local needs. Participating clinicians will be provided with the necessary tools (tobacco use screener, provider consult form, patient self-help materials) to support their engagement of the program.

Primary outcome measure

1. Program adoption: participation in TiTAN-Crete Global Bridges training program components and use of the Global Bridges Project Toolkit
2. Provider knowledge: knowledge of evidence-based tobacco treatment guidelines will be assessed using a brief 5-10 item knowledge assessment developed by project team
3. Theory of planned behavior constructs: attitudes, beliefs, control beliefs, subjective norms, normative beliefs, perceived behavioral control, intentions in next 6-months related to tobacco treatment delivery will be assessed using a pre-/post-intervention provider survey
4. Provider performance in the delivery of cessation treatments: performance in the delivery of each of the 3As ('ask, advise, assess') will be assessed via exit interview with eligible patients. The survey will ask participants to respond yes/no/don’t know regarding whether their PHC provider asked them about their smoking status (ask), advised them to quit smoking (advise), assessed their readiness to quit (assess), provided assistance with quitting (assist), prescribed pharmacotherapy, provided self-help materials and arranged follow-up support (arrange).

Secondary outcome measures

PHC provider satisfaction with the program and sustainability of the program will be assessed by survey at the end of trial. Providers will be asked to report on the quality of global bridges training program, quality of in-practice support, quality support materials, feasibility of maintaining tobacco treatment delivery in 80% of patients, barriers, suggestions for improvement and suggestions for continued engagement of primary care practitioner network.
