The search strategies were specifically designed to capture articles that were guided by or derived HRQOL models that were further analyzed in detail by the reviewers.
The inclusion of articles within this period aimed to capture articles which were published following the emergence of a seminal paper [ 10] which set the standards for health care quality.
This search strategy also made it more likely that we would capture articles for which established indexing terms did not exist such as social determinants of health and healthy communities.
We will search four databases: Ovid MEDLINE, PubMed (past 12 months to capture articles not yet indexed in MEDLINE), Cochrane Database of Systematic Reviews (Cochrane Library, Wiley) and the Cochrane Database of Abstracts of Reviews of Effects (DARE).
The intent was to devise a sensitive search, so as to cast a wide net in order to capture articles in a range of disciplines where the terminology is not standardized.
The other strength is that our search allowed us to capture articles and studies from 1999 to the present, which is the time that HCII has been most widely used.
To ensure that we had captured all articles, we completed an additional hand search of the reference lists of all articles that had been extracted for full-text review.
