This community based participatory project will evaluate a new day health program (DHP) in Toronto and answer the following questions: -What do people living with HIV (PHAs) identify as the important results the DHP should achieve? -What are the experiences of clinicians in providing care to clients with complicated health problems? How do clinicians improve the care clients receive at the DHP? -Does the DHP get the results that PHAs believe are important for their health and wellbeing? In 2016/2017, a new day health program (DHP) will open at Casey House Hospital in Toronto. The DHP was developed to 1) provide clinical care and ensure that all PHAs regardless of their background can access the program; 2) maintain and/or improve PHAs health status and quality of life; and 3) promote the best use of clinical resources. Our project is guided by an existing advisory group that provides guidance to the team in terms of which projects to conduct, how to conduct the projects, how to interpret what is found and who to direct the findings towards. We will also hire two peer research assistants (PRA) to work directly on the project and to help with to analyses, present findings and co-chair team meetings. To find out if the program works, we will collect and analyse data from clients of the program, clinicians who provide its services and medical records. To ensure others learn about what we find, we will host meetings in Toronto, present at conferences, write reports and scientific articles to reach as many PHAs, clinicians, policy makers and other researchers in Canada and the world.
