The INITIATE Study: Initiating Nicotine Dependence Treatment for Smokers Admitted to Emergency Departments

Ottawa Heart Institute Research Corporation1,208 enrolled

Overview

The INITIATE Study is a randomized controlled trial that is testing an intervention designed to increase long-term abstinence among tobacco smokers seen in emergency departments (ED) and other high-volume hospital and community ambulatory care settings. The intervention includes a behavioural incentive and tailored follow-up support on long-term smoking abstinence, health, healthcare utilization, and cost. Tobacco-related illnesses cost the healthcare system millions each year. Quitting smoking improves smoking-related outcomes, like the onset or management of heart disease, stroke, lung diseases, and several cancers. There are approximately 16 million visits to Canadian EDs each year; an estimated 3-4 million of these involve smokers. Effective quit smoking interventions exist, but are underutilized. Few hospital EDs, community healthcare centers, and other inpatient and outpatient clinics in Canada offer tobacco-use interventions. In order for clinicians to offer quit smoking support, interventions need to be simple given the realities of these high-volume environments. Considering that stopping smoking improves health outcomes, that tobacco-use is an important cause of preventable ED use, and the volume of smokers, Canadian EDs and other high-volume hospital and community ambulatory care settings are a missed opportunity in the initiation of quit smoking support. Our intervention has been designed to optimize uptake and smoking abstinence by including the most effective evidence-based behavioural and drug-related approaches, removing specific barriers and challenges that smokers face when trying to quit (e.g., affordability, low confidence and motivation), while packaging the intervention in a quick-to-initiate manner, making it ideal for fast-paced, complex environments.
