[Poor prognostic factors in patients hospitalized for COVID-19].

BACKGROUND: The clinical spectrum of COVID-19 varies from no or mild symptoms to pneumonia with fatal complications. The aim of the study was to find predictors of mortality and admission in the intensive care unit (ICU) in patients hospitalized for COVID-19. METHODS: Retrospective study of a cohort of patients admitted for COVID-19 between March 2020 and February 2021. Demographic, clinical, radiological and laboratory variables were described at admission. Independent predictors of mortality and ICU admission were identified by means of backward stepwise logistic regression and described in terms of odds ratio (OR) and 95% confidence interval (95%CI). RESULTS: A total of 883 patients were included, 51.8% men with a mean age of 68; 1.8% readmissions. 17.6% of patients died (n=154). The independent predictors of mortality were age (OR=1.071; 95%CI: 1.046-1.095), percentage of oxygen saturation (SatO2) (OR=0.938; 95%CI: 0.903-0.974), diastolic blood pressure (DBP, OR= 0.972; 95%CI: 0.955-0.989), creatinine (OR=1.516; 95%CI: 1.088-2.113), INR (OR=1.199; 95%CI: 1.012-1.419) and sodium (OR=1.082; 95%CI: 1.037-1.128). Eight percent of patients were admitted to ICU; the independent predictors were: male sex (OR=2.079; 95%CI: 1.099-3.935), age (OR=0.960; 95%CI: 0.942-0.979), SatO2 (OR=0.925; 95%CI: 0.889-0.962), creatinine (OR=1.551; 95%CI: 1.118-2.152) and C-reactive protein (CRP, OR=1.003; 95%CI: 1.000-1.007). CONCLUSION: The identification of independent predictors of mortality (age, SatO2, DBP, creatinine, INR, sodium) and ICU admission (sex, age, SatO2, creatinine, and CRP) allowed for the stratification of patients to adapt clinical care protocols to these findings, thereby improving medical decisions.

Factores de mal pronóstico en pacientes hospitalizados por COVID-19 / Poor prognostic factors in patients hospitalized for COVID-19

Fundamento: El espectro clínico de la COVID-19 varía entre sintomatología leve o ausente hasta neumonías con complicaciones mortales. El objetivo del estudio fue determinar los factores predictivos de mortalidad e ingreso en cuidados intensivos (UCI) en pacientes hospitalizados por COVID-19. Metodología: Estudio retrospectivo de una cohorte de pacientes ingresados por COVID-19 entre marzo de 2020 y febrero de 2021. Se describieron las variables demográficas, clínicas, radiológicas y analíticas al ingreso. Los predictores independientes de mortalidad e ingreso en UCI se identificaron mediante regresión logística por pasos hacia atrás y se describieron como odds ratio (OR) e intervalo de confianza al 95% (IC95%). Resultados: Se incluyeron 883 pacientes, 51,8% varones y edad media 68 años; el 1,8% reingresó. Fallecieron 154 pacientes (17,6%); los predictores independientes de mortalidad fueron: edad (OR=1,071; IC95%: 1,046-1,095), porcentaje de saturación de oxígeno (SatO2) (OR=0,938; IC95%: 0,903-0,974), tensión arterial diastólica (PAD, OR=0,972; IC95%: 0,955-0,989), creatinina (OR=1,516; IC95%: 1,088-2,113), INR (OR=1,199; IC95%: 1,012-1,419) y sodio (OR=1,082; IC95%: 1,037-1,128). El 8% de los pacientes ingresaron en UCI; las variables predictoras independientes fueron: sexo masculino (OR=2,079; IC95%: 1,099-3,935), edad (OR=0,960; IC95%: 0,942-0,979), SatO2 (OR=0,925; IC95%: 0,889-0,962), creatinina (OR=1,551; IC95%: 1,118-2,152) y proteína C reactiva (PCR, OR=1,003; IC95%: 1,000-1,007). Conclusiones: La identificación de predictores independientes de mortalidad (edad, SatO2, PAD, creatinina, INR, sodio) y de ingreso en UCI (sexo, edad, SatO2, creatinina y PCR) permite estratificar a los pacientes y adaptar los protocolos de atención clínica a estos hallazgos, mejorando las decisiones médicas.(AU)
