Patient characteristics of medical encounters at the Olympic Stadium during the Tokyo 2020 Olympic and Paralympic games[1]

Sekizaki Y, Hiden A, Yamamoto R, et al; Sasaki J · 2025 · Front Public Health

Summary

Retrospective analysis of nonathlete medical encounters at the Tokyo 2020 main Olympic Stadium (>3,000 nonathlete attendees under COVID spectator restrictions): 44 patients, dominated by heat-related illness and trauma; 7 (15.9%) required hospital transport. Timeline metrics: median 22 minutes to the on-site suite, 51 minutes under on-site care, 66 minutes total prehospital time. Attributes efficient triage and early treatment to specialized physicians and nurses stationed on site; linked hospital records captured downstream outcomes.

So what

A small but unusually complete Olympic-stadium dataset — it follows patients through to receiving hospitals and publishes the time intervals most event reports omit (22-min access, 51-min on-site care). The heat-and-trauma case mix at a summer Games echoes the endurance literature, and the timing benchmarks give planners rare numeric anchors for on-site care duration. Pairs with Fantou (Paris system-level) as venue-level Olympic ground truth for the LA28 planning cluster.

Key findings

  • Tokyo 2020 main stadium, nonathletes: 44 encounters, heat illness + trauma dominant
  • 15.9% required hospital transport; hospital records linked
  • Published time intervals: 22 min to suite, 51 min on-site care, 66 min prehospital
  • Specialist physicians/nurses on site credited for triage efficiency
  • Venue-level Olympic complement to the Paris system-level data; free PMC
