Background Terminally ill patients admitted to a hospital with noncancer conditions may miss palliative care (PC) service opportunities. This study aimed to examine the utilization of PC services among these hospitalized patients. Methods We conducted a cross-sectional study using the electronic medical records of noncancer patients admitted to internal medicine wards, intensive care units (ICUs), and cardiac intensive care units (CICUs). The patients meeting the Supportive and Palliative Care Indicators Tool (SPICT) criteria needed PC, and the patients who had advanced care plans or received PC consultations received PC services. We reported the proportions of patients with PC needs and PC services and their associated factors with the crude and adjusted odds ratios. Results Of 459 patients, 49.9% were female, and 92.6% were discharged alive. The mean age was 63 years old, and the average length of stay was 10 days. Additionally, 61.7% needed PC according to the SPICT criteria, but none of these patients received PC services. Patients with dementia/frailty, kidney disease, and heart disease had the highest rate of PC underutilization (100%, 96.8%, and 91.3%, respectively). Age, number of discharge medications, and length of stay were associated with needing PC, but some associations disappeared after the subgroup analysis. Conclusion None of the terminally ill noncancer patients in our study received PC services. The patients with dementia/frailty, kidney disease, and heart disease underutilized the services. A long length of stay and many discharge medications were associated with the PC needs and can be used to assess the PC needs.
