The study followed the approaches outlined by the PRISMA flow diagram and checklist, Meta-analysis of Observational Studies in Epidemiology (MOOSE) consensus statement and the Cochrane Handbook for Systematic Reviews of Interventions. Databases searched included PubMed, Google Scholar, ScienceDirect and the Cochrane Database of Systematic Reviews from January 1999 – December 2013. For search terms, we used a combination of controlled vocabulary and keyword terms representing delirium prevention, delirium intervention, targeted multi-component intervention, multi-component intervention, non-pharmacologic intervention, and Hospital Elder Life Program. Utilizing our systematic literature search strategy, 2334 articles were found. Of these, 2098 were excluded based on our screening criteria for relevance, language, age range, or non-human study subjects. A further 189 were excluded after full review yielding 46 articles which met our initial screening criteria. Upon further review, 32 of these did not meet our second-level inclusion criteria which required delirium prevention (not treatment), validated delirium assessment methods, multi-component non-pharmacologic interventions.
