At the Reference Meeting today, I mentioned the filters for healthcare quality and costs. They are found on the NICHSR (National Information Center on Health Services Research and Health Care Technology - whew!) website.
The website "provides specialized PubMed searches on healthcare quality and costs." "Results of searches on this page are limited to specific health services research areas (see definitions). " The "definitions" are hyperlinked and explain what is meant by that particular term.
The Categories are: Appropriateness / Process Assessment / Outcomes Assessment / Costs / Economics / Qualitative Research
Scope includes: Broad, sensitive search & Narrow, specific search.
The URL for the page is: http://www.nlm.nih.gov/nichsr/hedges/search.html
