Hypothesis
Which of the two delirium observation screening scales, the NEECHAM Confusion Scale or the Delirium Observation Screening (DOS) scale, has the best discriminative capacity for diagnosing delirium and which is more practical for daily use by nurses?
Conclusion
Nurses found the DOS scale significantly easier to use and more relevant to their practice compared to the NEECHAM scale.
Supporting Evidence
- The sensitivity and specificity of both scales were high, indicating their effectiveness in identifying delirium.
- Nurses rated the DOS scale as significantly easier to use than the NEECHAM scale.
- Delirium was diagnosed in 10.3% of the patients observed.
Takeaway
This study looked at two tools that help nurses spot confusion in older patients. The nurses liked one tool better because it was easier to use.
Methodology
The study was conducted on four wards of a university hospital where 87 patients were observed for symptoms of delirium using both scales.
Potential Biases
Nurses' prior knowledge of patients' conditions could influence their observations and ratings.
Limitations
The study was conducted at a single site with a small sample size, which may limit the generalizability of the findings.
Participant Demographics
Patients were aged 70 years and older, with an average age of 79 years, and 52% were female.
