Oslo Delirium Research Group

The group focuses upon different aspects of delirium in the elderly: Occurrence, risk factors, prognosis, prevention, treatment and pathophysiological mechanisms.

About us

Our main research focus on different aspects of delirium, or acute confusional state, in elderly people.

The group has studied delirium epidemiology and prognosis, carried out pharmacological and non-pharmacological intervention studies, and carried out studies in delirium pathophysiology.

The group members have comprehensive experience in sampling CSF and clinical data from patient cohorts.

We have established logistics for:

  • identifying hip fracture patients in the Emergency Department
  • providing consent from either the patient or a close relative
  • gathering proxy information on pre-fracture cognitive status by validated instruments
  • obtaining CSF and blood at the onset of spinal anaesthesia
  • monitoring the patients with validated tests during the perioperative phase regarding delirious symptoms, and
  • testing the patients cognitively at follow-up

Long-term goals

Through innovative research design, good utilization of the department's own patient materials, national and international networks and so on, we aim to develop into a leading European center for research on delirium.

In the years ahead, we will especially prioritize treatment research, epidemiology and research on pathophysiological mechanisms.

Our biobank spinal fluid samples from hip fracture patients who are well clinically mapped with respect to delirium represents a unique collection of biological materials, and we will therefore prioritize research on this to elucidate pathophysiological hypotheses in collaboration with basic scientists.

We have an ongoing recruitment of patients at several sites in Norway, and are continuously expanding our biobank.

Our group hosted the 12th annual meeting in the European Delirium Association at Hotel Bristol, Oslo November 16th – 17th 2017.
