Since the start of the COVID-19, Italy, and particularly the Northern region, Lombardia, has initially been the centre of the most numerous reports of confirmed cases of COVID-19 since the spread of the infection to Europe, reaching 5469 cases out of 9172 total cases in Italy (corresponding to 0.054% of the region population) within 2 weeks from the identification of the first Italian case at the end of February 2020. Data updated at 25 March 2020 reported 7503 deaths out of 57521cases in Italy. The overall number of patients requiring admission to hospital reached 23112, with another 3489 needing intensive care unit (ICU) management (4). The "Fondazione IRCCS Policlinico San Matteo" Pavia's main teaching and research hospital has become one of the main COVID Centers for the treatment of the disease. Several departments have been reassigned to the sole hospitalization of COVID-19 patients in addition to the Infectious Disease Department and the Intensive Care (ICU). Moreover, a dedicated emergency room (ER) has been set up.

All these measures have given rise to a large amount of clinical, imaging and laboratory data originating from different sources as well data regarding to type and length of stay in each of the ER, medical departments and ICU, that are of use for diagnostic and prognostic purposes. Also the Fondazione IRCCS Policlinico San Matteo has information obligations towards the Regional (Regione Lombardia) and National (Istituto Superiore di Sanità, ISS) authorities.

For these reasons we plan to set up a structured registry to collect these information on our Covid-19 patients using the secured REDCap platform resident on a server of the local Informative Services.
