OBJECTIVE To evaluate whether the Delirium Diagnostic Tool-Provisional (DDT-Pro), a 0-9 point scale with three items each representing symptoms from delirium's three core domains, differentiates subsyndromal delirium (SSD) from delirium and no delirium. METHODS We applied cluster analyses of DDT-Pro scores from 200 consecutive inpatients using three reference standards for delirium diagnosis to determine DDT-Pro cutoff values for delirium, SSD and no delirium groups. Clinical validators and…

Validation of the Delirium Diagnostic Tool-Provisional (DDT-Pro) in a skilled nursing facility and comparison to the 4 'A's test (4AT).
DDT-Pro is valid to detect delirium in SNF population where simple, structured tools with high sensitivity are needed and may have advantages over the 4AT.


Validation of the Delirium Diagnostic Tool-Provisional (DDT-Pro) With Medical Inpatients and Comparison With the Confusion Assessment Method Algorithm.
The Delirium Diagnostic Tool-Provisional had high validity and reliability in provisional delirium diagnosis by physicians and nonexpert clinicians, although further validation is warranted before widespread use can be recommended.
Frequency of delirium and subsyndromal delirium in an adult acute hospital population.
Background The frequency of full syndromal and subsyndromal delirium is understudied. Aims We conducted a point prevalence study in a general hospital. Method Possible delirium identified by testing
Initial validation of a brief provisional diagnostic scale for delirium
The DDT-Pro is supported as a measure of delirium following ABI, and further validation in ABI and other medical populations is recommended.
Subsyndromal delirium in the intensive care setting: Phenomenological characteristics and discrimination of subsyndromal delirium versus no and full-syndromal delirium
Phenomenologically, subsyndromal delirium was found to be distinct from and intermediate between noDelirium and full-syndromaal delIRium, indicating that the phenomenology of subsyNDromaldelirium is closer to full- Synderland deliria.
Validation of the Delirium Rating Scale-revised-98: comparison with the delirium rating scale and the cognitive test for delirium.
The DRS-R-98 is a valid measure of delirium severity over a broad range of symptoms and is a useful diagnostic and assessment tool that is ideal for longitudinal studies.
Phenotype of subsyndromal delirium using pooled multicultural Delirium Rating Scale--Revised-98 data.
SSD is intermediate in severity between nondelirious controls and full syndromal delirium, but its phenotype is more like delirial, and possible inclusion in DSM-V.
Comparison of diagnostic classification systems for delirium with new research criteria that incorporate the three core domains.
TMF research diagnostic criteria performed well, with more balanced sensitivity and specificity and the highest likelihood ratio for delirium identification, and may have advantages in biological research where delineation of this syndrome is important.
Delirium Phenotype by Age and Sex in a Pooled Data Set of Adult Patients.
A two-factor structure for delirium phenomenology, regardless of age and sex, was confirmed, with few significant differences between etiological groups.
Performance of the Delirium Rating Scale-Revised-98 Against Different Delirium Diagnostic Criteria in a Population With a High Prevalence of Dementia.
The DRS-R98 performs well despite differences across classification systems perhaps because it broadly assesses phenomenology, even in this population with a high prevalence of dementia.
Features of subsyndromal and persistent delirium
Full syndromaldelirium differs from subsyndromal delirium over time by greater severity of many cognitive and non-cognitive symptoms.
