Abstract
Background

Follow-up after hospital discharge of SARS-CoV-2 survivors represents a huge burden on the healthcare system. We attempt to assess the utility of symptoms and health-related quality of life questionnaire (SF-12) to identify SARS CoV2 pulmonary sequelae.

Methods

Prospective, non-interventional follow-up study. A cardiopulmonary exercise test, functional respiratory test (PFT), SF12 questionnaire were performed after hospitalization at six months after the first positive PCR smear.

Results

41 patients were included, female (39%), mean age 57.3±13.7 years. 70% persisted with symptoms. 46% presented a maximum oxygen consumption below 80% of predicted. SF-12 physical domain score was significantly reduced in patients with altered PFT (32.7 vs. 45.9; p<0.001) and obtained the best sensitivity and specificity to identify PFT alterations (AUC 0.862, Sensitivity 85.7%, Specificity 81.5%).

Conclusions

SF-12 questionnaire shows high sensitivity and specificity to detect SARS CoV2 survivors with pulmonary function alterations.

Resumen
Antecedentes y objetivos

El seguimiento tras el alta hospitalaria de los supervivientes de SARS-CoV-2 representa una enorme carga para el sistema sanitario. Intentamos evaluar la utilidad de los síntomas y el cuestionario de calidad de vida (SF-12) para identificar los pacientes con secuelas pulmonares por SARS-CoV-2.

Materiales y métodos

Estudio de seguimiento prospectivo observacional. Después de la hospitalización, a los 6 meses del primer frotis con PCR positiva se realizaron: una prueba de esfuerzo cardiopulmonar, pruebas funcionales respiratorias (PFR) y se aplicó el cuestionario SF-12.

Resultados

Se incluyó a 41 pacientes, el 39% eran mujeres, con una edad media de 57,3±13,7 años. El 70% persistía con síntomas. El 46% presentó un consumo máximo de oxígeno por debajo del 80% del predicho. La puntuación del dominio físico del SF-12 fue significativamente más baja en pacientes con PFR alteradas (32,7 vs. 45,9; p<0,001) y obtuvo la mejor sensibilidad y especificidad para identificar las alteraciones de las PFR (AUC 0,862; sensibilidad 85,7% y especificidad 81,5%).

Conclusiones

El cuestionario de calidad de vida SF-12 presenta una alta sensibilidad y especificidad para detectar a los sobrevivientes de SARS-CoV-2 con alteraciones de la función pulmonar.
