2. Methodology

A literature search was undertaken using a range of methods, including accessing key academic databases. ‘Grey’ literature of relevance to the study including policy documents and unpublished primary research was also accessed, with advice from a Research Advisory Group and interviews with key informants. In addition, contact was made with homecare managers to identify unpublished, locally commissioned work. Each source was analysed with the assistance of a Data Extraction Form that assisted the researchers to assess the quality of the research methodology adopted in each study and its relevance to the topic.
