144 Background: Patients with hematological malignancies are subjected to unique disease and therapy related complications that can lead to a substantial burden for them and their site of care. The emergency department has been the main gateway to acute care delivery for cancer patients, however, more recently cancer urgent care centers have been established to meet their specific care needs. This study describes the demographics and disease related characteristics of patients presenting to cancer urgent care centers and whether the visit prevented utilization of the emergency department. Methods: We performed a retrospective chart review of patients diagnosed with hematological malignancies seen in the cancer urgent care center at Henry Ford Cancer Institute between January 1, 2021, to December 31, 2022. We evaluated their demographics by race and gender, and then characterized them based on whether they were on active treatment during their visit, receiving standard of care or a clinical trial, and if they were early or late in their treatment course. Early treatment course was defined as within the first 2 cycles of therapy. We also evaluated the reason for their visit, and if an emergency department visit was prevented or not. Results: A total of 270 patients diagnosed with a hematological malignancy presented to the cancer urgent care center. 139 (51.5%) patients were male, and 141 (48.5%) were female. In terms of race, 145 (53.7%) were African American, followed by 72 (26.7%) Caucasian, with 53 (19.6%) of other races. The most common presenting reasons were gastrointestinal symptoms (63 patients [23.3%]), infectious symptoms (52 patients [19.3%]), and hematological symptoms (47 patients [17.4%]). 184 (68.1%) patients were on active treatment during their visit. Of these, 89 (33%) presented early in their treatment course. 227 patients (84%) were on standard of care treatment for their respective malignancy during the time of visit. 194 (71.9%) patient visits to the cancer urgent care prevented an emergency department visit. Conclusions: Our data demonstrates the major role of a cancer urgent care within a cancer care network. It showcases the large volume of patients with hematological malignancies that were seen in our cancer urgent care, and nearly 72% of these patients had an emergency department visit that was prevented. We will be further studying the seeming disparity in the racial proportion of such patients when compared to the race mix within the population as a whole.
