However, the cost of this strategy is unknown.Objective: We examined total cost of HFOT treatment compared with COT in real-world setting.Methods: We conducted a post-trial-based cost analysis from the perspective of a managed competition healthcare system, using actual records of billed costs. Cost categories include general ward, intensive care unit, procedures, imaging, laboratories, medications, supplies, and others.Results: A total of 188 participants (mean age 60, 33% female) were included. Average costs (and standard deviation) in the HFOT group were USD $7992 (7394) and in the COT group USD $ 10,190 (9402). Differences, however, did not reach statistical significance (P=0.093). However, resource use was always less costly for the HNFO group, with an overall percentage decrease of 27%. Two categories make up 72% of all savings: medications (41%) and intensive care unit (31%).Conclusion: For patients in ICU with severe COVID-19 the cost of treatment with HFOT as compared to COT is likely to be cost-saving due to less use of medications and length of stay in ICU.Keywords: SARS-CoV-2, COVID-19, cost analysis, economic evaluation, high-flow nasal oxygen, conventional oxygen therapy, high-flow oxygen therapy, clinical trial, cost, Colombia |
