Vall d'Hebron University Hospital has been, and still is, one of the reference centers during the COVID-19 pandemic. During these last months, it has been the hospital with the highest number of hospitalizations in Catalonia due to this cause, and it has also hosted the largest number of people in its ICU. In parallel, the research activity has not stopped, as this large number of patients has given the opportunity to professionals in the Vall d'Hebron Hospital Campus to obtain a high volume of data in order to investigate and gain knowledge about SARS-CoV-2.A good example of this scientific activity is the publication of more than 80 papers on COVID-19 with the participation of professionals from Vall d'Hebron since the beginning of the pandemic until today. This number, which is still growing day by day, makes Vall d'Hebron the second hospital in the State with the most publications on COVID-19. The first of these articles was published on March 25, which shows that, in an emergency situation like this, researchers have been working to understand more about the virus as quickly as possible.These publications cover multiple approaches to the virus and the disease, both from the point of view of clinical care and also basic research, and with the participation of multiple services and research groups. These include results of studies led by professionals from Vall d'Hebron, collaborations with other centers and hospitals, and also consensus documents as a result of the participation in national and international scientific societies.The publication of the papers includes some high impact journals such as American Journal of Respiratory Critical Care Medicine, Annals of Surgery, BJOG An International Journal of Obstetrics and Gynaecology, Intensive Care Medicine or The Lancet Oncology. All of them have been published open access, as a result of an international agreement between scientific publishers in the context of COVID-19 to promote the exchange of information among all professionals working in the fight against SARS-CoV-2.
