Delirium Measurement Info Cards

Example of info card PDF

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 We have developed info cards for tools used to assess delirium in adults, in both ICU and non-ICU settings, as well as in pediatric populations.

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 from subsequent studies that are not included in these cards. Where feasible, we have added selected references to additional review articles that include these instruments. The adult info card collection includes 22 assessment tools for delirium screening, diagnosis or severity, and 4 brief screening tools. The pediatric collection includes 5 pediatric delirium screening or diagnostic tools. Choose below to view the Adult or Pediatric Delirium Measurement Info Cards.
