Abstract
Background

There are few data on the clinical characteristics of COVID-19 patients who require blood transfusion. We aimed to investigate the clinical characteristics and indication for transfusion in COVID-19 patients seen during the epidemic's first wave.

Material and methods

Cross-sectional study that included all consecutive COVID-19 patients admitted to the Hospital Clínic of Barcelona, Spain, from mid-March to mid-May 2020.

Results

A total of 80 patients received 354 RBC units, 116 plasma units, and 48 platelet units. Median age was 71 years (IQR: 62–76), and 59 (74%) were males. In total, 138 of the 261 transfusion episodes that involved RBCs (59%) were related to spontaneous (n=94) or procedure-related (n=44) bleeding. Spontaneous bleeding was more frequent in the retroperitoneal space and the gastrointestinal apparatus. Tracheostomy with endotracheal intubation, surgical interventions, and cannulation of femoral vessels were the main procedures behind non-spontaneous bleeding. Most patients (91%) were on anticoagulants, mostly intermediate- or full-dose heparin.

Conclusion

Anticoagulation-related bleeding was a leading cause of blood transfusion in COVID-19 patients during the epidemic's first-wave.

Resumen
Introducción

Las características de los pacientes con COVID-19 transfundidos son poco conocidas. Nuestro objetivo fue investigar el perfil clínico y el motivo de la transfusión en los pacientes con COVID-19 vistos durante la primera ola de la epidemia.

Material y métodos

Estudio transversal que incluyó a todos los pacientes con COVID-19 transfundidos en el Hospital Clínic de Barcelona entre marzo y mayo de 2020.

Resultados

Ochenta pacientes recibieron 354 unidades de hematíes, 116 de plasma y 48 de plaquetas. La edad mediana fue de 71 años y 59 (74%) eran hombres. En total, 138 de los 261 episodios de transfusión de hematíes (59%) estaban relacionados con hemorragia espontánea (n=94: principalmente retroperitoneal y gastrointestinal) o con procedimientos invasivos (n=44: principalmente traqueostomía, cirugía, y canulación de vasos femorales). El 91% de los pacientes recibía tratamiento anticoagulante el día de la transfusión o los dos días previos, sobre todo heparina a dosis intermedia o completa.

Conclusión

El sangrado relacionado con la anticoagulación fue el motivo principal de transfusión en los pacientes con COVID-19.
