Background: An estimated 9.6 million people died from cancer globally in 2018, which is a reflection of the quality of patients' end-of-life care and its costs. Aim: To estimate direct medical costs of the last 30 days of oncology patients admitted to an inpatient clinic and to evaluate factors associated with medical costs at the end of life. Design: Cost-of-illness study with data from a retrospective cohort. Setting/Participants: We included patients aged 18 and older who were diagnosed with incurable cancer and who were admitted to a tertiary hospital in Brazil between January 1, 2018 and December 31, 2019. Results: Our sample included 109 patients with an average age of 69 (61‒76). The median overall survival was 4.3 (.9‒12.9) months. The median cost per patient per day related to hospitalization was BRL 119 (73‒181)/United States dollars [USD] 21 (13‒33). The cost of medication was BRL 66 (40‒105)/USD 12 (7‒19), representing 55.46% of costs while that of materials and supplies was BRL 30 (18‒49)/USD 5 (3‒9). In the multivariate analysis, when the limitation of interventions was recorded in the medical record, the median cost is reduced by BRL 50 (USD 9) per patient per day. Conclusions: The median cost per patient per day was BRL 119 (73‒181). The recording of limitations of therapeutic interventions in the medical record was a predictor variable that influenced the final medical cost of patients, suggesting that medical practice and decision-making in end-of-life care impact costs.
