What prompts patients to present with delirium?

PURPOSE

To explore the recognition, response and understanding of delirium in families and carers of hospitalised patients.

METHODS

All adults with delirium admitted to an acute medical unit were included. Delirium was diagnosed by a specialist geriatrician. The responder who sought medical advice for each patient was interviewed using a delirium recognition questionnaire. Vital status was ascertained at four months.

RESULTS

Sixty patients were included (mean age 85, SD 6.8 years). Reported symptoms included drowsiness and lack of responsiveness, though these were less commonly recognised as being due to delirium. 76% received medical advice within 24 h, although two responders took > 1 week. One-third of responders had never heard of delirium. Delirium knowledge among responders was variable.

CONCLUSION

Overall awareness and knowledge of delirium was poor. Community delirium education and public health initiatives may improve rapidity of recognition, delirium assessment, and potentially health outcomes.
