Using documents to investigate links between implementation and sustainability in a complex community intervention: The PRISM study

Abstract

The increasing imperative to find what works in health services has meant a rise in research trialing interventions deemed 'complex'. While the strength of these interventions comes from taking a 'whole of problem' approach using multiple and inter-linking strategies, ways of examining implementation are under-explored. Building sustainability is an important part of implementing complex intervention research, but this too has received little exploration in the implementation literature. This paper explores issues of implementation and sustainability by examining the case of PRISM (Program of Resources, Information and Support for Mothers), a community randomised trial in Victoria, Australia..
