How to identify existing literature on patients’ knowledge, views, and values: the development of a validated search filter
Keywords:Patient Preference, Patient Participation, Patient Rights, Patient-Centered Care, Information Storage and Retrieval/Methods, Sensitivity and Specificity
Objective: The research sought to establish validated search filters for retrieval of studies on patients’ knowledge and values.
Setting: 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.
