Abstract

ImportanceInformation about the severity of Omicron is scarce.ObjectiveTo report the respective risk of ICU admission in patients hospitalized with Delta and Omicron variants and to compare the characteristics and disease severity of critically ill patients infected with both variants according to vaccination status.DesignAnalysis from the APHP database, called Reality, prospectively recording the following information in consecutive patients admitted in the ICU for COVID-19: age, sex, immunosuppression, vaccination, pneumonia, need for invasive mechanical ventilation, time between symptom onset and ICU admission, and in-ICU mortality. Retrospective analysis on an administrative database, “Système d’Information pour le Suivi des Victimes” (SI-VIC), which lists hospitalized COVID-19 patients.Setting39 hospitals in the Paris area from APHP group.ParticipantsPatients hospitalized from December 1, 2021 to January 18, 2022 for COVID-19.Main outcomes and measuresRisk of ICU admission was evaluated in 3761 patients and Omicron cases were compared to Delta cases in the ICU in 888 consecutive patients.ResultsOn January 18, 45% of patients in the ICU and 63.8% of patients in conventional hospital units were infected with the Omicron variant (p < 0.001). The risk of ICU admission with Omicron was reduced by 64% than with Delta (9.3% versus 25.8% of cases, respectively, p < 0.001). In critically ill patients, 400 had the Delta variant, 229 the Omicron variant, 98 had an uninformative variant screening test and 161 did not have information on variant screening test. 747 patients (84.1%) were admitted for pneumonia. Compared to patients infected with Delta, Omicron patients were more vaccinated (pConclusion and relevanceCompared to the Delta variant, the Omicron variant is less likely to result in ICU admission and less likely to be associated with pneumonia. However, when patients with the Omicron variant are admitted for pneumonia, the severity seems similar to that of patients with the Delta variant, with more immunocompromised and vaccinated patients and no difference in adjusted in-ICU mortality. Further studies are needed to confirm our results.

Abstract

Los estados de salud son resultado del efecto de los múltiples factores sociales determinantes de la salud. Las inequidades en salud aparecen como consecuencia de la interacción adversa de dichos factores determinantes, que llevan a disparidades en salud entre diversas poblaciones y entre integrantes de una misma población, las cuales pueden catalogarse como injustas y evitables. Aunque la población europea ha alcanzado altos niveles de salud y esperanza de vida como nunca antes, las inequidades en salud entre y dentro de los países europeos se encuentran aun ampliamente extendidas y en incremento en algunas áreas. La crisis económica actual, además, muestra impactos negativos significativos sobre los factores determinantes sociales de la salud y, por consiguiente, sobre la salud de las poblaciones. Adicionalmente, la información actual sugiere que las respuestas gubernamentales de varios países europeos ante la crisis fallaron en su objetivo de proveer soluciones integrales y sostenibles, en la medida en que estas no toman en cuenta a la salud. Sin embargo, los sistemas de salud, sociales y económicos sólidos parecen actuar preventivamente ante los efectos negativos sobre los factores sociales determinantes de la salud y sobre la salud misma. Por otra parte, el desarrollo de estructuras gubernamentales intersectoriales y de estrategias como la evaluación de impacto en salud, pueden fomentar la reducción de disparidades en salud consideradas como injustas.
