Аннотация
BACKGROUND: Delirium is a common symptom following a traumatic brain injury that is often overlooked by healthcare professionals. Early detection of posttraumatic delirium is crucial to improving patient outcomes and quality of life. The 4 As Test (4AT: alertness, attention, abbreviated mental test-4, and acute mental changes) is a brief and rapid tool for delirium assessment with acceptable reliability and validity. However, the 4AT has not yet been translated for use in the Taiwanese population.
OBJECTIVE: To translate the 4AT into Traditional Chinese (TC-4AT), assess its reliability and validity, and explore the clinical effects of delirium in patients with a traumatic brain injury.
METHODS: This prospective observational study was conducted at the neurosurgery wards of 2 Taiwanese hospitals. Patients who were aged 20 years or older, were diagnosed with a traumatic brain injury, and had a Glasgow Coma Scale score between 13 and 15 were included. Interrater reliability was assessed, and validity was verified using criterion-related comparisons with the Short Confusion Assessment Method. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition criteria were employed to assess the sensitivity and specificity of the TC-4AT for screening posttraumatic brain injury delirium.
RESULTS: A total of 100 patients with an average age of 67 years were enrolled, of whom 10% were diagnosed with delirium based on the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition criteria. The interrater reliability of the TC-4AT was 1.00. Patients with delirium tended to have a longer hospital stay than those without delirium (13 days vs. 7 days) although the difference was nonsignificant (P = 0.28). In terms of criterion validity, patients diagnosed with delirium using the Short Confusion Assessment Method had a significantly higher score on the TC-4AT than those not diagnosed with delirium (P < 0.001). The receiver operating characteristic curve indicated that the optimal cutoff point was 4, with sensitivity, specificity, and area under the characteristic curve of 0.90, 0.94, and 0.96, respectively.
CONCLUSION: The TC-4AT is an accurate tool for delirium assessment that aids early detection and in informed decision-making in preventive care.
