Research Relevance

The Canadian Institute for Research on Health Services found that 80% of costs are attributable to 10% of the population. Many of these patients with chronic disease are frequent users of services because of their complex needs and present poorer indicators of health and a high mortality rate. This represents a priority issue for the health system as well as for these patients

V1SAGES Program

The V1SAGES Program, led by Dr. Hudon proposes to increase our understanding of the needs of these frequent users of services, and to develop, implement and evaluate innovative approaches in primary care, such as case management, to improve car for frequent users of health services through partnerships between helping professionals in health and social services and community organizations. This work presents great potential to improve the efficiency of the health care system.
