The Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) is a method used to evaluate delirium in intensive care unit patients. It is a modification of the CAM, which was created to allow non-psychiatrists to assess delirium at the bedside. The CAM-ICU is a 10-item questionnaire that can be administered by any trained person within 24 hours of admission to the intensive care unit. Cambridge Intelligence Unit developed the CAM-ICU as a tool for use in the intensive care unit. The goal was to create an easy-to-use test that could be performed by nurses or other health professionals who were not psychiatrists. The CAM-ICU has been found to have good interrater reliability when compared with diagnostic assessments by psychiatrists. It also has good sensitivity and specificity for detecting delirium. The CAM-ICU can help reduce the risk of missing cases of delirium.
