Official title

A Pilot Study of the Psychometric Properties of the "Stanford Proxy Test for Delirium" (S-PTD): a New Screening Tool for the Detection of Delirium

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Although there are several tools available for the screening of delirium among the medically ill, they all have some limitations. First, none of the available tools have been validated against newly developed and published DSM-5 (Diagnostic and Statistical Manual) or ICD-10 (International Statistical Classification of Diseases and Related Health Problems) criteria. Additionally, all the screening/diagnostic tools presently available have the same limitation, they all require significant patient involvement and participation (e.g., questions and activities) in order to complete the assessment. By definition, delirium is a neuropsychiatric disorder characterized by disturbance in attention and awareness, and additional disturbance in cognition (e.g., memory deficit, disorientation), language, visuospatial ability, or perception. The intrinsic characteristics of delirium seem to interfere with the patient's ability to participate and complete many of the tasks associated with delirium evaluation itself. Finally, most available tools seem to narrowly focus on some neurocognitive areas of delirium, but not being comprehensive enough. In contrast, the S-PTD is designed so it can be completed by the nursing staff caring for the patients, the medical personnel most intimately involved with the care and aware of the behaviors exhibited by the patient during the course of their hospital stay. The idea is that nurses will complete the screening tool (hence the term "by proxy"), based on the behaviors and interactions observed during the course of a conventional "nursing shift", to determine whether the patient meets current neuropsychiatric criteria for the diagnosis of delirium.
