MGMI — Mass Gathering Medicine, cited to source

A WORKING REFERENCE FOR MASS GATHERING MEDICINE · UPDATED WEEKLY FROM THE LITERATURE · —

Crowds are predictable.
The medicine that meets them should be too.

Three questions govern medical care at any mass gathering: what does the evidence say, what do the experts recommend, and what does the law require? This site answers all three — from — checked sources, the official guidance that shapes provision, a 51-jurisdiction atlas of the law, the cases that show what fails, and a curriculum that teaches it. For the physicians, medics, and planners who staff concerts, marathons, festivals, and stadiums.

Pillar One

The Literature

What the peer-reviewed evidence says. Every paper in the library carries a Crossref-verified DOI, a structured summary, and a “so what” for practice — organized by domain, with state-of-the-evidence syntheses across all twelve domains.

Library The Evidence Library Every indexed paper — searchable, filterable, each with a citation rail. The raw material of the field.

Canon The Landmark Collection The papers that built the field, annotated — from Arbon 2001 to the modern crowd-physics literature. Physician-reviewed selection, with reading pathways for medics, students, and directors.

Syntheses State of the Evidence What the models can and cannot do, domain by domain — where the evidence is strong, where it thins, and where prediction honestly ends. Twelve domains, including the white spaces.

Pillar Two

Expert Recommendations

What the organizations advise. Position statements, consensus documents, and official guidance from ACEP, NAEMSP, the Green Guide, the SGSA, WHO, and their peers — shelved, sourced, and dated, so you know whose recommendation you are standing on and how current it is.

Shelf The Guidelines Shelf Position statements and official guidance documents, each with issuing body, currency year, and canonical source link — the difference between a guideline and a rumor of one.

MGMI MGMI Expert Recommendations Where the shelf is silent or the evidence has outrun it: our own numbered recommendations, each argued from cited evidence and marked draft until physician review.

Method How Content Earns Publication DOI verification, evidence grading, and the review gate. Nothing publishes unreviewed; drafts say so.

Pillar Three

States & Municipalities

What the law requires. A complete state-by-state atlas of mass-gathering statutes and rules — triggers, physician mandates, permit mechanics — plus the municipal tier where cities set their own staffing tables. Researched from official legal sources, quoted verbatim, honest about the gaps.

States The 50-State Regulatory Atlas All 51 jurisdictions mapped — the survey is complete. Twenty-two carry real event-medical law in statute, with DC a twenty-third through permits — from Connecticut's 1 physician per 1,000 attendees to twenty clean none-founds. In physician review.

Cities The Municipal Tier Ten major metros surveyed: San Francisco's five-level EMS matrix, Chicago's MD-staffed-tent tier, Houston's ordinance adopting the ESA tables — and the striking silences (Los Angeles).

Context Medical Direction & Legal — the Evidence Jaslow found six states with mass-gathering laws in 1999. The atlas is the replication, a generation later — and the count has nearly quadrupled. Manuscript in preparation.

Pillar Four

Plan, Learn, Remember

The working tools: a calculator built only on models you can cite, a curriculum that teaches the field, and the case registry that keeps its hardest lessons.

Tools Planning Calculator & Composer Side-by-side predictions from verified published models only, with a citation on every line — then a staffing draft you can defend.

Learn The Event Medicine Rotation A twelve-subject curriculum with a live, interactive question bank — 303 items you can practice now, every one cited to the paper it was written from. Modules across EMS, nursing, and physician tiers; banks in physician review.

Registry Lessons-Learned Registry Hillsborough to Astroworld — ten structured case studies with timelines, contributing factors, and what changed. Minimum three sources per case. Published.
