There is considerable variability in delirium measurement tools, with a wide variety of instruments for screening, diagnosis and severity available for clinical and research use. As a result, it can be difficult for researchers and clinicians to choose a tool that is most appropriate for their purpose. To assist with this issue, we created “info cards” that provide a standardized summary of commonly used delirium measurement tools that were identified through a systematic review and an online survey that we conducted in 2017. To submit information about a delirium instrument not included in this list, contact us at email@example.com.
About the info cards:
These cards are populated with information from each instrument’s original validation study. Thus, there may be additional test performance characteristics or other information about each instrument that are not included in these cards. Where feasible, we have added selected references to additional review articles that include these instruments.
