Can we better detect suffering in unresponsive cancer patients?

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Patient Inclusion Criteria: 1. Patients with advanced cancer. Advanced cancer is defined as locally invasive, metastatic or recurrent cancer. Hematologic malignancies will also be included. 2. Patients who are admitted to the acute palliative care unit (APCU) at MD Anderson Cancer Center. 3. Patients who are unable to respond to questioning in the past 24 hours as determined by the attending physician, fellow physicians, or nursing staff of the APCU. 4. Patients who are considered to be actively dying, as defined as likely to die during the admission and not regain consciousness. The physical exam findings that will be utilized to help define those patients who are actively dying may include one but not limited to one of the following symptoms: pulseless of the radial artery, Cheyne-stokes breathing, peripheral cyanosis, apnea periods, respiration with mandibular movement, turbulent airway noise produced on inspiration and/or expiration due to airway secretions commonly known as the "death rattle", and loss of nasolabial folds The presence of these signs will be based on the reporting of the attending physician, fellow physicians or nursing staff of the APCU. 5. Patients who have an unpaid adult caregiver at bedside age 18 years or older, who is willing and able to provide informed consent and who has been present at bedside for at least 3 hours a day. Patient Exclusion Criteria: 1. Patients who had a hyperactive or mixed delirium in which they either had high level of arousal due to delirium or had mixed episodes of arousal and agitation with periods of unresponsiveness. 2.
