Acute symptomatic complications among patients with advanced cancer admitted to acute palliative care units: A prospective observational study.

BACKGROUND

Limited information is available on the symptomatic complications that occur in the last days of life.

AIM: We documented the frequency, clinical course, and survival for 25 symptomatic complications among patients admitted to acute palliative care units.

DESIGN

Prospective longitudinal observational study.

MEASUREMENTS: Their attending physician completed a daily structured assessment of symptomatic complications from admission to discharge or death.

SETTING/

PARTICIPANTS

We enrolled consecutive advanced cancer patients admitted to acute palliative care units at MD Anderson Cancer Center, USA, and Barretos Cancer Hospital, Brazil.

RESULTS

A total of 352 patients were enrolled (MD Anderson Cancer Center = 151, Barretos Cancer Hospital = 201). Delirium, pneumonia, and bowel obstruction were the most common complications, occurring in 43%, 20%, and 16% of patients on admission, and 70%, 46%, and 35% during the entire acute palliative care unit stay, respectively. Symptomatic improvement for delirium (36/246, 15%), pneumonia (52/161, 32%), and bowel obstruction (41/124, 33%) was low. Survival analysis revealed that delirium (p < 0.001), pneumonia (p = 0.003), peritonitis (p = 0.03), metabolic acidosis (p < 0.001), and upper gastrointestinal bleed (p = 0.03) were associated with worse survival. Greater number of symptomatic complications on admission was also associated with poorer survival (p < 0.001).

CONCLUSION

Symptomatic complications were common in cancer patients admitted to acute palliative care units, often do not resolve completely, and were associated with a poor prognosis despite active medical management.
