Hypothesis
The study investigates the incidence of delirium and related factors among older adults in a neurological ICU during the COVID-19 pandemic.
Conclusion
The incidence rate of delirium among older adults in the neurological ICU was found to be 16.9%, with several significant factors identified.
Supporting Evidence
- The incidence rate of delirium was 16.9%.
- 49.8% of patients were categorized as subsyndromal delirium.
- Dexmedetomidine use was identified as a significant factor affecting delirium.
- Longer ICU stays increased the odds of developing delirium.
- Blood urea nitrogen levels were significantly associated with delirium.
- Visual impairment was found to be a risk factor for delirium.
- Older age was associated with a higher risk of delirium.
Takeaway
Older people in the ICU can get confused, and this study looked at why that happens, finding that certain medications and health issues make it more likely.
Methodology
A retrospective study using electronic medical record data and logistic regression analysis.
Limitations
The study is limited to a single tertiary hospital and may not be generalizable to all settings.
Participant Demographics
