Hypothesis
What is the incidence of delirium in patients admitted to three intensive care units of a teaching hospital?
Conclusion
Delirium is a common disorder in ICUs, and specific tests should be used regularly for accurate diagnosis and treatment.
Supporting Evidence
- The incidence of delirium was found to be 21.4% among the patients studied.
- 88.9% of patients developed delirium within the first 5 days in the ICU.
- Patients with delirium had a longer average stay in the ICU compared to those without.
Takeaway
Delirium is when patients get confused in the hospital, and it happens a lot in intensive care units. Doctors need to check for it more often.
Methodology
Patients were evaluated daily using the CAM-ICU tool, and the study assessed the correlation of clinical suspicion with the CAM-ICU diagnosis.
Potential Biases
Potential bias in clinical diagnosis by attending physicians, medical residents, and nurses.
Limitations
The study was limited to three ICUs and a relatively small sample size.
Participant Demographics
Patients admitted to three intensive care units in a teaching hospital in Brazil.
