How to identify existing literature on patients' knowledge, views, and values: the development of a validated search filter.
OBJECTIVE
The research sought to establish validated search filters for retrieval of studies on patients' knowledge and values.


METHODS
Two nonprofit organizations in the Netherlands were studied for guideline development.


METHODS
An existing filter was adapted to three bibliographic interfaces. After defining the scope, a reference database was built for the development of the new filters. The performance of the new filters was validated in different disease categories.


RESULTS
Sensitivity, specificity, precision, negative predictive value, and accuracy were (%): 90.5/98/77/99.2/97 (MEDLINE-Ovid), 90.1/98.8/79.3/99.5/98.3 (PubMed), and 93.1/98.4/81.8/99.6/98.7 (Embase).


CONCLUSIONS
The filters provide pragmatic tools for searching for patients' issues. Further optimization and validation is recommended.
