Mass-gathering medicine: creation of an online event and patient registry.

INTRODUCTION/PROBLEM: A review of the mass-gathering medicine literature confirms that the research community currently lacks a standardized approach to data collection and reporting in relation to large-scale community events. This lack of consistency, particularly with regard to event characteristics, patient characteristics, acuity determination, and reporting of illness and injury rates makes comparisons between and across events difficult. In addition, a lack of access to good data across events makes planning medical support on-site, for transport, and at receiving hospitals, challenging. This report describes the development of an Internet-hosted, secure registry for event and patient data in relation to mass gatherings.


Descriptive; development and pilot testing of a Web-based event and patient registry.


Several iterations of the registry have resulted in a cross-event platform for standardized data collection at a variety of events. Registry and reporting field descriptions, successes, and challenges are discussed based on pilot testing and early implementation over two years of event enrollment.


The Mass-Gathering Medicine Event and Patient Registry provides an effective tool for recording and reporting both event and patient-related variables in the context of mass-gathering events. Standardizing data collection will serve researchers and policy makers well. The structure of the database permits numerous queries to be written to generate standardized reports of similar and dissimilar events, which supports hypothesis generation and the development of theoretical foundations in mass-gathering medicine.
