Development and Application of a Quality Assessment Tool for Oncological Question Prompt Lists.

No specific quality criteria yet exist for question prompt lists (QPLs), so this study aims to develop a quality assessment tool to then use for an evaluation of online-available QPLs. An online search was conducted for German-language QPLs using different internet search engines and terms. A wide range of existing quality criteria for patient information was adapted to the field of QPLs to build an assessment tool and evaluate all identified QPLs by four independent raters. All new quality criteria were applicable to QPLs. The overall quality of 46 oncological QPLs was low, though the tool's subcategories were mostly fulfilled to over 80% by at least one QPL. For-profit organizations published lesser quality than medical organizations. The quality of breast- and prostate-cancer-specific QPLs was higher than that of general ones. High-quality QPLs could be created if more aspects were taken into account, but the available QPLs only focus on few quality aspects. The ambiguous results of effectiveness studies to date may be a result of vastly differing quality of the QPLs used for the interventions. The criteria provided in this study present a solid basis to assess the quality of QPLs. The creation of future QPLs as well as effectiveness studies should be more firmly based on quality criteria.
