Brief Summary

Delirium is an acute brain-organic syndrome: its clinical manifestation and form are results of a highly complex pathophysiology. Delirium is a serious clinical problem in hospitalized adults. It is the most common neuropsychiatric complication of hospitalization and is associated with high patient burden, increased morbidity and mortality, prolonged length of stay, higher costs, and institutionalization. An early, accurate diagnosis as well as an adequate management are critical to the continued health and functional independence of the affected patients. Prevention strategies contain pharmacological and non-pharmacological interventions. However, their clinical success (effectiveness) is limited and the evidence for the use of pharmacological interventions for the prevention or management of delirium is scarce. The prediction of delirium has become a new promising topic in clinical research. New approaches like the implementation of wearable sensors, in particular wearable accelerometer devices to record movements related to delirium are promising. In this study, the study procedure only includes wearing a consumer-grade sensor on the wrist of the not-dominant hand. This way, vital parameters are measured in order to identify patterns.

Patients will be enrolled if they agree to participate and provide written informed consent.

You may qualify if:

  • Female and male inpatients aged 65 years or older
  • Cognitive ability to understand, consent to and participate in the study
  • Fluent in German
  • Provision of written informed consent

You may not qualify if:

  • The presence of acute delirium,
  • or a delirium diagnosis made within the last 4 weeks prior to hospitalization,
  • The likelihood of an alcohol withdrawal delirium (CAGE Score \>1)
  • Limited knowledge of the German language
