The aim of this research project is to better understand and address the health needs and service requirements of people with multiple, complex needs under the purview of Community Living British Columbia (CLBC). The proposed research project will build on existing research and fill important gaps in knowledge regarding the health of people with a multiple complex needs designation and effective service delivery mechanisms at points of intersection with the healthcare system. This research project will advance CLBC's research efforts through two key objectives. The first is to better understand the health-related needs of this population, which includes an analysis of health-related contacts (type and frequency), outcomes, and costs associated with this population. In BC, much is not known about the health-related needs of this group. The second objective is to identify and learn from promising practices in BC – specifically, what is being done that works for this population and why, with particular attention to issues of sustainability and scalability. Although findings from CLBC's qualitative research highlight the need for significant systemic change in the delivery of services for people with multiple complex needs, it also identified "pockets of excellence" in BC where local or regional solutions have emerged as examples of practice excellence. Through this objective, I will focus on services that directly intersect with the healthcare system (e.g., acute care, residential detox/treatment, etc.) and address underlying social determinants of health, including, for example: homelessness, poverty, and issues of gender and race (indigenous people). The research will include an evaluation of selected services. In addition, an inventory of services for the multiple, complex needs people in BC will be developed.
