Phenomenological subtypes of delirium in older persons: patterns, prevalence, and prognosis
Yang FM, Marcantonio ER, Inouye SK, Kiely DK, Rudolph JL, Fearing MA, Jones RN.. Psychosomatics, 2009-05-01
Topic: Risk, prevention and care in population studies
Background Delirium is an acute confusional state that is common, preventable, and life-threatening. Objective The authors investigated the phenomenology of delirium severity as measured with the Memorial Delirium Assessment Scale among 441 older patients (age 65 and older) admitted with delirium in post-acute care. Methods Using latent class analysis, they identified four classes of psychomotor-severity subtypes of delirium: 1) hypoactive/mild; 2) hypoactive/severe; 3) mixed, with hyperactive features/severe; and 4) normal/mild. Results Among those with dementia (N=166), the hypoactive/mild class was associated with a higher risk of mortality. Among those without dementia (N=275), greater severity was associated with mortality, regardless of psychomotor features, when compared with the normal/mild class. Conclusion The data suggest that instruments measuring delirium severity and psychomotor features provide important prognostic information and should be integrated into the assessment of delirium.
Key findings
- Results Among those with dementia (N=166), the hypoactive/mild class was associated with a higher risk of mortality.
- Among those without dementia (N=275), greater severity was associated with mortality, regardless of psychomotor features, when compared with the normal/mild class.
- Conclusion The data suggest that instruments measuring delirium severity and psychomotor features provide important prognostic information and should be integrated into the assessment of delirium.

How this study scored 45/100
Published in a peer-reviewed journal. Scored zero for study design, effect reported and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 26 of the 58 points we could judge it on, which is 45 out of 100.
