Abstract

Background

The study aimed to describe patient characteristics and outcomes by PaO₂/FiO₂ (PAFI) and degree of inflammation.

Methods

Retrospective cohort study with data on patients collected from March 1^st, 2020 to March 1^st,2023, from the Spanish SEMI-COVID-19 Registry. Non-nosocomial patients with data on PAFI (<100 vs. 100-200 vs. 200-300 vs. >300) who received corticosteroids (CS) for COVID-19 in the first 48 h of admission were included in the study. 5,314 patients met the inclusion criteria for the present study. The primary outcome was in-hospital mortality.

Results

Higher in-hospital mortality was found in the groups with PAFI< 100 (51.5% vs. 41.2% vs. 25.8% vs. 12.3%, P<.001). They also required more NIMV, IMV, and ICU admission, and had longer hospital stays. Those patients with PAFI>300 and 4-5 high-risk criteria presented higher mortality than the patients with PAFI 200-300 and only 1-2 criteria of analytical inflammation. Risk factors associated with higher in-hospital mortality were age (OR = 1.06; 1.05-1.06), moderate (OR = 1.87; 1.49-2.33) and severe (OR = 2.64; 1.96-3.55) degree of dependency, dyslipidemia (OR = 1.20; 1.03-1.39), higher Charlson index (OR = 1.19; 1.14-1.24), tachypnea on admission (2.23; 1.91-2.61), the higher number of high-risk criteria on admission, and lower PAFI on admission. Female gender (OR = 0.77; 0.65-0.90) and the use of RDSV (OR = 0.72; 0.56-0.93) were found to be protective factors.

Conclusions

The lower the PAFI and the higher the degree of inflammation in COVID-19, the higher the in-hospital mortality. Inflammatory escalation precedes respiratory deterioration and should serve as an early predictor of severity to deciding the use of anti-inflammatory/immunosuppressive therapy.

期刊介绍： Revista Clínica Española published its first issue in 1940 and is the body of expression of the Spanish Society of Internal Medicine (SEMI). The journal fully endorses the goals of updating knowledge and facilitating the acquisition of key developments in internal medicine applied to clinical practice. Revista Clínica Española is subject to a thorough double blind review of the received articles written in Spanish or English. Nine issues are published each year, including mostly originals, reviews and consensus documents.
