Abstract
The new version of DSM-5 provides nearly the same criteria as DSM-IV for delirium with an exception. The DSM-5 requires a disturbance in awareness while DSM-IV, a disturbance in consciousness. Awareness is not the same as consciousness. In this study we examined the concordances between awareness and consciousness and the agreement between DSM-5 and DSM-IV. All acute medical admissions 70 years and over. Exclusion criteria: terminal phase of illness, severe aphasia, intubated. Those included were assessed on Day 1, 3, 7, 10 of their admission. During the assessment each individual was tested with: MoCA, DRS-98R, CAM, RASS and the subscale of levels of consciousness and awareness of surroundings from RCDS; APACHE II, CAPE and BARTHEL index. Demographic data and a medication list were also recorded. 123 participants; Mean age: 81.3 SD (6.7) range 70-100 years old Females 60(48.9%) Delirium according CAM 21 (17.1%) Delirium 23 (18.7%) Subsyndromal delirium 28 (22.8%) No delirium 72 (58.5%) Previous cognitive decline: 76 (61.8%) RCDS (awareness and consciousness) Mean awareness: 0.4, SD (0.8) Mean consciousness 0.4 SD (0.8). Correlation (agreement) between awareness and consciousness Kendal's Tau =260, p=0.026 Using the awareness definition of delirium 8 participants with full awareness of surroundings have been indentified as delirious according to DRS 98, while using the consciousness definition 12 participants where indentify as delirious. DSM-IV and DSM-5 detect two slightly distinct populations with delirium. Awareness and consciousness are not the same. DSM-5 is more restrictive in indentifying delirium.
