Delirium symptoms

Delirium in advanced cancer requires urgent palliative care referral and emergency response

Across 2 studies involving over 689 patients and 60 international experts, delirium emerges as a critical emergency in advanced cancer. A cohort study of 689 advanced cancer patients in home palliative care found delirium and loss of consciousness among the most frequent triggers for emergency calls, with 17.1% of patients (145 of 689) generating 176 emergency contacts over 7 months. Pharmacological intervention at home managed most cases satisfactorily without hospital transfer. An international Delphi consensus statement with 60 palliative care experts across 3 rounds established delirium as 1 of 11 major referral criteria for outpatient specialty palliative cancer care, achieving over 70% expert agreement alongside spinal cord compression and brain metastases. Caregivers should treat new-onset confusion, agitation, or altered consciousness in cancer patients as an urgent signal requiring immediate professional evaluation.

In the international Delphi consensus study with 60 experts rating 61 criteria over 3 rounds, delirium achieved the pre-defined consensus threshold of 70% or more agreement. It was established as 1 of 11 major referral criteria for outpatient specialty palliative cancer care, alongside other acute conditions such as spinal cord compression and brain or leptomeningeal metastases.

Among 689 advanced cancer patients in home palliative care, delirium and loss of consciousness ranked among the most frequent reasons for 176 emergency calls made by 145 patients (17.1%) over 7 months. Emergency calls were primarily made by relatives, with a mean of 2.2 family members (SD 1.5) present during home visits. Calls were considered justified by physicians in most cases. Pharmacological intervention at home was the primary management strategy and was rated satisfactory in the majority of cases, supporting that these emergencies can often be handled without hospital transfer.
