After discharge from critical care, the mortality rate in the following year is low (7%). The risk of dying is maximum at 10e day (amounting to regarding 1%), then it clearly decreases continuously. Nearly 85% of these deaths occur within the first 50 days of discharge from critical care.
Another interesting fact: the rate of patients who died in the year following going to critical care for Covid is lower than that of patients with flufor all age groups (Figure 2).
The DREES specifies that “ total mortality at one year is of the same order of magnitude, 31% compared to 30% once morest patients admitted for influenza because intra-hospital mortality was higher among patients admitted to critical care for Covid (especially over 60s) ».
While several studies have shown that men infected with SARS-CoV-2 have a greater risk of death than women during hospitalization, this analysis does not find no significant association between gender and risk of death (at equivalent age, comorbidities and epidemic wave) once the patients have been discharged from hospital. Moreover, as expected, mortality increases with age and the level of pre-existing comorbidities. Finally, while the risk of death in hospital is greater in the second and third waves compared to the first, the risk of death one year following discharge is the same for the three epidemic waves.
