BRONCHITIS, RECRUITMENT
As shown in supplementary Table Participating health professionals indicated that many of their patients met eligibility criteria for the STOP RCT. However, several comments on barriers for recrutment were reported in Fig. 
Perceptions reported health professionals participating in the STOP RCT concerning barriers for recruitmenet, and constraints relative to study organizationFor tobacco-cessation specialists other types of barriers to recruitment were identified:“We are already doing too much smoking cessation (we are even proactive; we teach medical students on rotation to prescribe patches to smokers who come for bronchitis, even if they don’t ask for it, in the belief that this proactive approach described in some studies will lead patients to at least try and discuss the experience with a doctor). Therefore, recruitment [for the STOP RCT] is not easy. In the health center where we already do a lot of smoking cessation (the doctors and the specialized nurse); thus the majority of eligible patients encountered already have patches or had already been offered them in the past year.”“Very often my patients are already on NRT so it is rather difficult to recruit new ones.”
