The likelihood of hospital ICU use in the last month of life was influenced by several patient characteristics. Male patients were more likely to use ICU care (adjusted odds ratio [AOR], 1.11; 95% CI, 1.05-1.16) (Table 2). ICU use decreased sharply with age. Compared with married patients, single patients were significantly more likely to use ICU care, but divorced, separated, and widowed patients used significantly less. Comorbidity level incrementally increased the propensity of ICU use. Compared with patients with lung cancer (Taiwan’s leading cause of cancer death), patients with hepatoma and pancreatic or bile duct cancers were less likely to use ICU care (AOR, 0.52; 95% CI, 0.47-0.57, vs AOR, 0.70; 95% CI, 0.60-0.82, respectively). However, patients with hematologic malignancies and esophageal cancer were significantly more likely to use ICU care (AOR, 2.75; 95% CI, 2.46-3.07, vs AOR, 1.65; 95% CI, 1.45-1.89, respectively). Cancer patients with a distant-metastatic disease were less likely to use ICU care before death (AOR, 0.60; 95% CI, 0.55-0.65). Increasing postdiagnosis survival substantially decreased the propensity for using ICU care at EOL.
