Events involving a high number of participants should be planned and implemented with the primary objective of guaranteeing the highest possible level of safety, which is ever more essential in the recent years due to the risk of terrorism, violence, and highly transmissible pathogens like coronavirus disease 2019 (COVID-19).The aim of this study was describing health care management of the Vasco Modena Park July 1, 2017 concert by the artist Vasco Rossi that involved 220,000 participants, more than doubling the population of Modena (Italy), the city hosting the event.Data were retrospectively collected from all health care registers used during the concert. Descriptive data regarding the event were recorded, as well as the medical records generated by the advanced medical posts.For analysis, patients were divided into two groups: the LOW-Severity (admission code green) and HIGH-Severity (admission codes yellow and red). The number of patients within the inclusion period was 1,088; there were 953 green discharge codes (97.74%), 16 yellow (1.64%), and six red (0.61%). Patients who needed a second-level assessment were 5.85% (57 events). HIGH-Severity patients needed to be further evaluated in 45.45% of the cases versus 4.93% of the LOW-Severity patient group (P value <.001).The health care management proved adequate to the number of participants and the severity of patients. Descriptive data reported add the mass-gathering database useful for further events.
