Summary
Health outcome reporting for mass gatherings (MGs) is inconsistent, hindering event planning. Standardizing reporting is crucial for improving future event safety and medical care.
Area of Science:
- Disaster medicine
- Public health
- Event management
Background:
- Mass gatherings (MGs) health outcomes are often reported using case reports.
- Existing reports show significant variation in included data, making comparisons difficult.
- The extent of this reporting inconsistency has not been previously quantified.
Purpose of the Study:
- To analyze patterns in post-event medical reporting within the scientific literature.
- To identify and document inconsistencies in how mass gathering health outcomes are reported.
Main Methods:
- A systematic review of English-language case reports published between 2009 and 2018.
- Studies were sourced from Prehospital and Disaster Medicine (PDM) and Current Sports Medicine Reports (CSMR).
- A framework of 27 data categories was developed to analyze reporting consistency.
Main Results:
- 54 publications met inclusion criteria, with 42 being full case reports.
- Only 13 out of 27 data categories were consistently reported in over 50% of publications.
- Inconsistent terminology, variable data retrievability, and non-uniform reporting of event details, risks, and outcomes were observed.
Conclusions:
- Current case reports on mass gatherings are largely descriptive, lacking explanatory depth.
- Significant heterogeneity in reporting impedes the scientific advancement of MG planning and health outcome improvement.
- Standardizing reporting practices is essential to enhance the quality and utility of future event-related research.
