Ethics approval and consent to participate
: The project has been approved by the Ethics Committee of the university hospital “Azienda Ospedaliero-Universitaria Meyer” of Florence on March 2017 (Hospital Institution Review board Cod 87). Data were obtained from an electronic database using ICD-9-CM. A specific informed consent was not considered necessary because this was a descriptive epidemiological study performed on administrative data, which are routinely collected from any hospitalized patient after obtaining his/her consent. Furthermore, no human experimentation was foreseen by the study and patient information was anonymized and de-identified prior to analysis.
