Clinical outcomes by supplemental oxygen use in remdesivir-treated, hospitalised adults with COVID-19 - 15/10/23
Highlights |
• | Real-world study of hospitalised COVID-19 patients treated with remdesivir. |
• | Higher mortality and longer hospitalisation in HFO compared to LFO and NSO groups. |
• | Early initiation (upon admission) of remdesivir has mortality benefit. |
• | Remdesivir use and outcomes differed by country. |
Abstract |
Background |
Clinical trials show different effects of remdesivir on clinical outcomes relative to COVID-19 severity at hospital admission; in Europe, there are few real-world data.
Methods |
A multicentre, multinational retrospective cohort study in adult patients hospitalised with PCR-confirmed COVID-19 was conducted to understand remdesivir clinical use in different countries and to describe outcomes for patients receiving remdesivir stratified by oxygen use. Primary endpoints were all-cause mortality at day 28 and hospitalisation duration. Patients were categorised by baseline disease severity: no supplemental oxygen (NSO); low flow oxygen ≤ 6 litres (l)/minute (LFO); high flow oxygen > 6 l/minute (HFO).
Results |
Four hundred and forty-eight (448) patients (72 [16.1%] HFO; 295 [65.8%] LFO; 81 (18.1%] NSO) were included; median age was 65 years and 64% were male. Mortality was higher in patients on HFO (rate 23.6%) compared to LFO (10.2%; p = 0.001) or NSO (6.2%; p = 0.002). Duration of hospitalisation was longer in patients on HFO (13 days) compared to LFO (9 days; p = 0.003) and NSO (9 days; p = 0.021). Patients who initiated remdesivir ≥ 2 days compared to within a day of hospitalisation had a 4.2 times higher risk of death, irrespective of age, sex, comorbidities, and oxygen support at baseline. Requirement for mechanical ventilation/ECMO and readmission within 28 days of discharge was similar across groups. Remdesivir use and outcomes differed by country.
Conclusions |
A higher mortality rate and duration of hospitalisation was seen in remdesivir-treated COVID-19 patients on HFO compared to LFO and NSO. Initiation of remdesivir upon admission as opposed to delayed initiation has a mortality benefit.
