Imagine if we could leverage existing infrastructure to enhance how we better manage and support patients with chronic disease in the community? Three of the most common chronic diseases worldwide are Diabetes Mellitus (DM), Congestive Heart Failure (CHF) and Chronic Obstructive Pulmonary Disease (COPD). These diseases are on the rise and currently cost the Canadian health care system billions of dollars every year including the cost of unnecessary hospitalizations and ED visits. The current structure of the health care system does not have the capacity to effectively care for these patients in the future. Paramedics are currently employed 24-7 to provide Emergency Medical Services (EMS) in urban, rural and settings across Canada. They are highly trained health care practitioners that are connected to and mobile in the community and currently work in a medically delegated act model with physicians where they regularly rely on independent judgment giving them a significant advantage in assessing patients. The evidence already tells us that collaborative Chronic Care Models can improve patient outcomes and decrease overall health care utilization. What if we leveraged this incredible resource to enhance patient care in the community setting? We hypothesize that training paramedics in chronic disease management and having them conduct home visits to assess and treat patients under medical delegation of the patients' primary care physicians will reduce the rate of acute care hospitalization and, ED visits, EMS utilization, and Family Health Team (FHT) utilization for COPD, DM and CHF patients.

So how do we find out if it works? We propose a randomized controlled trial (Level 1 evidence) to rigorously study the effectiveness of community paramedicine model versus standard care. The primary study question is whether non-emergency community paramedics conducting home visits to undertake assessments and evidence-based treatments of patients under the medical delegation of primary care physicians will decrease the rate of hospitalization for chronic disease patients. Our intervention will be applied in select Ontario Family Health Team (FHT) patients diagnosed with COPD, CHF and DM. We plan to randomize 695 patients: patients randomized to the intervention group will be assessed and treated during home visits by community paramedics. Patients randomized to the control group will continue to receive usual care from the participating Family Health Teams. The number of hospitalizations, hospital length of stay, ED visits, EMS utilization and cost-effectiveness will be compared using existing administrative databases. We have been doing a feasibility trial since March of 2013 to confirm our recruitment and data collection approaches.

The intent of the Partnerships for Health System Improvement (PHSI) program is to strengthen Canada's health care system through collaborative, applied and policy-relevant research. Our project has been developed in strong partnership with Centennial College; Central Community Care Access Centre; York Region Emergency Medical Services; Health For All Family Health Team; Markham Family Health Team; Rescu, Li Ka Shing Knowledge Institute, St. Michael's Hospital; and the Sunnybrook Centre for Prehospital Medicine. We have also partnered directly with the Primary Care Branch of the Ministry of Health and Long Term Care to ensure a fruitful integrated knowledge translation plan at the policy level. By engaging all of the key stakeholders upfront we have already created the necessary linkages to make this health system innovation possible.

If found to be effective, the simplicity of the community paramedicine model allows it to be scalable in various ways for EMS services across the country. It could also be expanded to include management of several other conditions. Funding is only getting tighter and health care capacities will be increasingly challenged in the coming years - innovation in how we use existing resources is the future of health system improvement. Community paramedicine is a perfect example of this type of innovation and our project will provide the evidence needed by decision makers and knowledge users to significantly impact primary care policy making for the future.
