Oncology and Palliative Care Integration Model: A Cost Analysis Study in a Brazilian Hospital Setting.

Background: In 2019, the São Paulo State Cancer Institute (ICESP) implemented a novel model integrating Oncology with Palliative Care specialists. We evaluated the impact of this model on healthcare resource utilization and costs. Methods: We analyzed data from all patients who passed away in February (1 month prior to implementation) and November (8 months after model implementation group) at ICESP, Brazil. Healthcare utilization data, including emergency department visits, hospital and intensive care unit admissions, chemotherapy, and radiotherapy use, were retrieved from Electronic Medical Records. Unit cost values were obtained from the administrative database. Results: A total of 198 patients who died in February and 196 in November were included in the analysis. Groups exhibited similarities in sex, age, ECOG, cancer type, previous outpatient palliative care consultations, and place of death (ward: 56.6% pre-intervention, 50% post-intervention). The mean cost per patient was US$13,226.29 pre-intervention and US$11,445.82 post-intervention (P = .007). Statistically significant differences were noted in days hospitalized in the surgical ward (227 vs 115), emergency department visits (233 vs 45), chemotherapy sessions (140 vs 26), and radiotherapy sessions (146 vs 10). Excluding outpatient treatments, the total costs for chemotherapy and radiotherapy in the last 30 days of life were US$16,924.45 pre-intervention and US$7851.65 post-intervention. Reductions were more pronounced in patients with ECOG 3-4 (P = .039). Conclusion: Our data suggests that the integration model was associated with a reduction in potentially inappropriate treatments during the last month of life, leading to decreased healthcare utilization and costs.
