Using linking systems to build capacity and enhance dissemination in heart health promotion: a Canadian multiple-case...

The purpose of this paper is to examine the utility of linking systems between public health resource and user organizations for health promotion dissemination and capacity building, and to identify factors related to the success of linking systems. The design is a parallel-case study using key informant interviews and content analysis of project reports (synthesized qualitative and quantitative data) of three provincial dissemination projects of the Canadian Heart Health Initiative-Dissemination Phase. Each provincial project used linking activities with public health user groups including meetings, skill building, resources, collaboration, networking and research feedback to facilitate capacity building for and implementation of heart health promotion activities. This paper presents empirical examples of linking system designs, activities, and qualitative and quantitative changes in the public health user groups' health promotion capacity, program delivery and sustainability. The findings indicate enhanced health promotion skills, partnerships, resources, infrastructure, and increased programming and sustainability in the targeted public health organizations of all three provincial projects. Identified barriers to the success of linking systems included lack of appropriately skilled personnel, funds, buy-in and leadership. We conclude that linking systems can be flexibly used to build capacity and disseminate health promotion innovations, and suggest conditions for success.
