Brief Summary

The investigators designed a randomised multicenter clinical trial for patients with advanced cancer who are admitted to the medical oncology ward or high-care hospice. On admission all patients with advanced cancer will be asked to participate in this study. Consenting patients will be submitted to delirium observation screening according to the DOS. Subsequently DOS screening will be performed twice weekly until discharge. Each patient who's score is \> 3 (DOS positive) is showing significant symptoms of delirium and will be submitted to the revised Delirium Rating Scale (DRS-R-98) to confirm diagnosis. To test validity of the DOS scale for this particular population, each DOS positive score will be randomly matched with a patient with a DOS score \< 3 (DOSnegative) and this patient will also be submitted to DRS-R-98. When diagnosis of delirium is confirmed by DRS-98, patients will be randomised between treatment of delirium with olanzapine or haloperidol (usual care). Treatment in both groups will consist of identification and management of underlying aetiologies of delirium if possible and adding neuroleptic medication for symptom control. Patients who recover from their delirium episode as well as their caregivers will be asked to complete the Delirium Experience Questionnaire (DEQ) to assess recall of the delirium experience and the degree of distress related to the delirium episode.

Outcome Measures

Primary Outcomes (1)

  • DRS-R-98 severity rating score

    Primary endpoint for this trial is a DRS-R-98 severity rating score \<15,25, as this is a measure for establishing clearance of delirium.

    Until clearance of the delirium signs or for a maximum of 2 weeks

Secondary Outcomes (1)

  • Delirium resolution rate

    Until clearance of the delirium signs or for a maximum of 2 weeks

Study Arms (2)

Olanzapine

EXPERIMENTAL
Drug: Olanzapine

Haloperidol

ACTIVE COMPARATOR
Drug: Haloperidol

Interventions

After randomisation to olanzapine treatment, olanzapine will be started at an initial dose of 2,5 - 5 mg orally or intramuscularly, after 2 hours subsequent titration of dosage will be based on clinical judgement with a maximum of 20 mg per 24 hours divided over a maximum of 3 gifts. Sustenance dose will consist of half of the total titrated dose per 24 hours in one gift.

Also known as: Zyprexa
Olanzapine

After randomisation to haloperidol treatment, haloperidol dosing will be titrated, with repeated dosing of 0,5 - 2mg orally or subcutaneously every 40 minutes until signs of delirium diminish, with a maximum of 20 mg orally or 10 mg subcutaneously per 24 hours. Sustenance dose will consist of half of the total titrated dose per 24 hours in one or two gifts.

Also known as: Haldol
Haloperidol

Eligibility Criteria

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patient has been diagnosed with advanced cancer
  • Age ≥ 18
