Use of Medication at the Roskilde (Denmark) Music Festival 2015 - A Prospective Observational Study of 15,133 Treated Attendees.

Background: Outdoor music festivals (OMFs) attract large numbers of guests and benefit from the help of large numbers of volunteers. Studies have previously described the injury patterns at OMFs, but no studies have described the use of medication and sales from on-site pharmacies at a large OMF.

Method: The usage of medication and prescriptions in the Medical Health Care Organization (MHCO), including sales from the on-site pharmacy, at the Roskilde (Denmark) Festival 2015 were prospectively recorded.
