What Happens When Someone Has a Medical Emergency at Your Event?

medical emergency at event
The scenarios every event organiser fears – and why your choice of medical provider could make all the difference between life and death
A medical emergency at event can happen at any time. It’s 9:30 PM at your outdoor festival. The headline act is midway through their set when a 45-year-old man near the front barrier suddenly clutches his chest and collapses. The crowd around him starts shouting for help, phones are filming, and security is trying to clear a path.
What happens next depends entirely on the medical cover you’ve chosen for your event.
This isn’t a hypothetical scenario – it’s based on a real case from one of our events. And the difference between basic first aid response and professional CQC-registered medical cover could literally be the difference between life and death.

The Reality: Medical Emergencies Will Happen

As an event organiser, you might hope that serious medical emergencies won’t happen at your event. But hope isn’t a strategy, and the statistics are clear:
  • Large events (3,000+ attendees) typically see 3-5% medical presentation rates
  • Serious emergencies requiring hospital treatment occur at roughly 0.1-0.3% of events
  • Peak medical demand usually occurs in a single 1-2 hour window
  • Alcohol, heat, and crowd dynamics significantly increase emergency risk
The question isn’t whether medical emergencies will happen – it’s whether you’ll be prepared when they do.

Case Study 1: Chest Pain at a Music Festival

The Scenario: A 45-year-old male attendee collapsed with severe chest pain during a headline performance. Crowd density was high, lighting was poor, and the nearest hospital was 20 minutes away.
Basic First Aid Provider Response:
  • Security calls for first aid team
  • First aider arrives with basic kit
  • Takes pulse, checks breathing
  • Calls 999 and waits for ambulance
  • Limited pain relief options
  • No diagnostic capability
  • Total response time to definitive care: 35+ minutes
Basic First Aid Provider Response:
  • Security calls for first aid team
  • First aider arrives with basic kit after 8 minutes (crowd access difficulties)
  • Takes pulse, checks breathing, recognises chest pain
  • Calls 999 – this becomes a Category 2 call (serious but not immediately life-threatening)
  • NHS ambulance service target response time: 18 minutes (but often much longer due to current pressures)
  • First aider provides basic comfort measures while waiting
  • Actual ambulance arrival: 35 minutes (system under pressure, no available crews nearby)
  • NHS crew performs 12-lead ECG, recognises STEMI, establishes IV access
  • NHS crew would also bypass local A&E and go directly to cardiac centre (they know the system too)
  • Total time from collapse to specialist cardiac treatment: 87 minutes
CQC-Registered Provider Response (What We Did):
  • Paramedic on scene within 4 minutes
  • Patient safely moved to our ambulance using a carry chair (the crowd made stretcher access impossible)
  • Once in the ambulance: 12-lead ECG performed immediately, showing clear signs of a heart attack in progress
  • IV line established, strong pain relief administered to keep patient comfortable
  • Critical clinical decision: ECG showed this was a STEMI – a specific type of heart attack where a major artery is completely blocked
  • Hospital choice matters: We called the specialist cardiac centre directly (bypassing local A&E just like NHS crews would)
  • Direct phone call to the cardiac catheter lab with ECG results transmitted electronically
  • Hospital team prepared and waiting when we arrived
  • Total time from collapse to specialist cardiac treatment: 52 minutes
The 35-Minute Difference: Both our team and the NHS ambulance crew would make the same clinical decisions – recognising the STEMI and going directly to the cardiac centre. The critical difference is response time. Those 31 minutes (35 vs 4 minutes to get on scene) plus the additional time for crowd extrication and assessment add up to a 35-minute delay in getting life-saving treatment started.
In STEMI cases, every minute counts. The “door-to-balloon” target is 90 minutes from first medical contact to surgery. Starting that clock 35 minutes earlier can mean the difference between minimal heart damage and significant long-term disability.

Case Study 2: Acute Behavioural Disturbance at Electronic Dance Music Event

The Scenario: A 21-year-old male became extremely aggressive and agitated after suspected stimulant use at an electronic dance music festival. Security were called when he became violent toward other attendees. He was sweating profusely, hyperventilating, and making growling sounds – classic signs of Acute Behavioural Disturbance (ABD) brought on by chemical stimulants.
Basic First Aid Provider Response:
  • First aiders called to assist with “aggressive male”
  • Arrive to find security restraining patient face-down on ground
  • Patient extremely agitated, sweating, almost growling at those nearby
  • First aiders consider this primarily a security issue, attempt verbal de-escalation
  • 999 called – police advised they will attend but may be delayed
  • Patient remains restrained by several security officers for several minutes
  • Each time restraint is reduced, patient becomes violent again
  • After 8 minutes, patient suddenly becomes calm and quiet
  • On release, security find patient has stopped breathing – cardiac arrest from positional asphyxia
  • First aiders begin CPR, second 999 call made
  • Result: Preventable cardiac arrest, potential fatality
CQC-Registered Provider Response (What We Did):
  • First responder recognises ABD presentation immediately, calls for paramedic support
  • Clinical assessment: Stimulant-induced acute behavioural disturbance requiring chemical restraint
  • Paramedic works under PGD (Patient Group Direction) to administer IM diazepam 10mg
  • Patient positioned safely (not face-down) during restraint to prevent positional asphyxia
  • First dose partially effective – patient calmer but still agitated
  • Second dose IM diazepam administered after 15 minutes
  • Patient sufficiently calm to be sat upright and safely restrained
  • Transferred to stretcher and ambulance for safe transport to ED
  • Result: Patient conscious throughout, no cardiac arrest, safe outcome
The Critical Difference: ABD is a medical emergency, not a security problem. Patients in this state have altered brain chemistry from stimulant drugs and cannot be reasoned with or physically restrained safely for extended periods.
Positional asphyxia occurs when someone is restrained face-down – their own body weight restricts breathing, leading to cardiac arrest. Security staff aren’t trained to recognise this risk, but medical professionals are.
Our paramedic recognised that this patient needed chemical restraint (controlled sedation) rather than physical restraint. The IM diazepam calmed his brain chemistry enough to make him manageable without the life-threatening risks of prolonged physical restraint.
The Stark Reality: Without proper medical intervention, ABD cases frequently result in cardiac arrest from positional asphyxia during restraint. This isn’t security’s fault – they’re doing what they think is right. But ABD requires medical treatment, not security management.

Case Study 3: Synthetic Opioid Overdose – The Hidden Killer

The Scenario: Security report a “collapsed male” near the main stage. A 22-year-old is found unconscious with severely depressed breathing – only 4 breaths per minute. He’s unresponsive to verbal stimuli and has pinpoint pupils. His friends insist “he only took pills and ketamine” – they have no idea he’s consumed synthetic opioids mixed into other substances.
Basic First Aid Provider Response:
  • First aider recognises dangerously slow breathing rate
  • Calls 999 – Category 2 response, NHS ambulance target 18 minutes
  • Administers 100% oxygen via face mask
  • Patient continues to deteriorate – breathing becomes more laboured
  • First aider begins bag-valve-mask ventilation as patient approaches respiratory arrest
  • Critical problem: Without naloxone, patient will not recover regardless of breathing support
  • Actual ambulance arrival: 28 minutes (system pressures)
  • NHS crew arrives with naloxone, begins treatment
  • Total time from collapse to naloxone administration: 28+ minutes
  • Risk: Prolonged hypoxia, potential brain damage or cardiac arrest
CQC-Registered Provider Response (What We Did):
  • First responder on scene within 3 minutes, immediately recognises depressed respiratory rate
  • Intranasal naloxone 1.8mg administered immediately from response bag
  • Nasopharyngeal airway inserted to secure airway
  • Clinical support called, full set of observations obtained (BP, pulse, oxygen saturation)
  • Patient shows slight improvement but still critically unwell
  • Transferred to ambulance, IV access established
  • IV naloxone commenced – synthetic opioids require much higher doses than traditional heroin
  • Multiple doses administered: Total of 5 separate naloxone doses over 20 minutes
  • Patient closely monitored for re-sedation (naloxone wears off faster than synthetic opioids)
  • Emergency transfer to ED
  • Total time from collapse to first naloxone: 3 minutes
  • Patient outcome: Full recovery to normal consciousness
The Synthetic Opioid Reality: This patient had unknowingly consumed fentanyl analogues mixed into what he thought were party drugs. Synthetic opioids are now commonly found in pills sold as MDMA, cocaine, or other substances at festivals and events.
Why This Case Nearly Became Fatal:
  • Synthetic opioids are 50-100 times stronger than heroin
  • Users often don’t know they’ve taken opioids – they think they’ve taken something else
  • Standard naloxone doses often insufficient – synthetic opioids require multiple, higher doses
  • Re-sedation is common – naloxone wears off in 30-90 minutes, synthetic opioids last much longer
The 25-Minute Difference: Our immediate naloxone administration (3 minutes vs 28+ minutes) prevented:
  • Prolonged hypoxia (lack of oxygen to the brain)
  • Potential brain damage from oxygen deprivation
  • Cardiac arrest from respiratory failure
  • Death – synthetic opioid overdoses are frequently fatal without immediate intervention
The Hidden Epidemic: Synthetic opioid contamination of recreational drugs is now the leading cause of overdose deaths at music events. Users have no idea they’re at risk because they don’t think they’re taking opioids. Traditional drug education doesn’t prepare people for this threat.
Why Clinical Knowledge Matters:
  • Recognition: Identifying opioid overdose vs other causes of collapse
  • Immediate treatment: Having naloxone immediately available, not waiting for ambulances
  • Dosing expertise: Understanding that synthetic opioids need much higher naloxone doses
  • Monitoring: Watching for re-sedation and repeat dosing requirements
  • Equipment: IV access for more effective naloxone administration

Medical Emergency at Event: What Every Organiser Must Know

The Legal Reality: Your Duty of Care

When a serious medical emergency occurs at your event, several legal questions arise:
Did you provide adequate medical cover for the risks involved? Courts will examine whether your medical provision was appropriate for your event type, size, and risk profile.
Was your medical provider competent to handle the emergency? This includes both clinical competence and appropriate equipment/medication access.
Did you follow industry best practice? The Purple Guide increasingly recommends CQC-registered providers for larger events.
Could the outcome have been different with better medical cover? This is where the difference between basic first aid and professional medical cover becomes legally significant.

Insurance Implications: When Claims Arise

Your insurance provider will scrutinise your medical provision decisions if a serious incident occurs:

Questions They’ll Ask:

  • Was your medical provider appropriately qualified?
  • Did they have adequate insurance (medical malpractice, not just public liability)?
  • Were they CQC-registered for treatment of disease/injury?
  • Did you conduct a proper medical needs assessment?

The Financial Reality:

  • Medical negligence claims can exceed £1 million
  • Public liability may not cover clinical decision-making
  • Inadequate medical cover can void your event insurance

What Event Organisers Tell Us After Serious Incidents

“We never thought something like this would happen at our event. When it did, we realised how unprepared we were with basic first aid cover.”
“The difference in response was incredible. Our previous provider would have just called an ambulance and waited. Your team probably saved his life.”
“It was terrifying watching someone collapse at our festival. Knowing we had proper medical cover made all the difference – not just for the patient, but for our peace of mind.”

The Questions You Should Ask Your Medical Provider

Before your next event, ask potential medical providers:
Clinical Capability:
  • “What medications can you administer on-site?”
  • “Do you have ECG capability and clinical decision-making authority?”
  • “What’s your experience with drug-related emergencies?”
Emergency Response:
  • “How quickly can you get to any point on my site?”
  • “What’s your protocol for serious cardiac events?”
  • “How do you communicate with receiving hospitals?”
Qualifications and Insurance:
  • “Are you CQC-registered for treatment of disease/injury?”
  • “Do you carry medical malpractice insurance?”
  • “Who makes clinical decisions at my event?”
If they can’t answer these questions confidently, they’re not equipped to handle serious medical emergencies.

The Cost of Getting It Wrong

Human Cost:
  • Preventable deaths or permanent disability
  • Trauma for attendees who witness medical emergencies
  • Long-term impact on families affected
Financial Cost:
  • Medical negligence claims
  • Event cancellation or reputation damage
  • Insurance premium increases or coverage withdrawal
Legal Cost:
  • Health and Safety Executive investigations
  • Corporate manslaughter charges in extreme cases
  • Personal liability for event organisers

Prevention vs Response: The Complete Picture

Professional event medical cover isn’t just about responding to emergencies – it’s about preventing them:

Risk Assessment and Mitigation

  • Identifying site hazards that cause injuries
  • Crowd management to prevent crushing incidents
  • Environmental monitoring for heat-related illness

Early Intervention

  • Identifying unwell attendees before they become emergencies
  • Managing intoxication before it becomes dangerous
  • Treating minor conditions before they escalate

Preparedness

  • Pre-positioned resources for predicted peak demand
  • Direct communication with local hospitals
  • Coordination with police and other emergency services

Making the Right Choice for Your Event

The scenarios we’ve shared aren’t designed to frighten you – they’re real situations that professional event medical providers handle regularly. The question is whether your medical cover is prepared for these realities.
When choosing medical cover, remember:
It’s not about if serious emergencies will happen – it’s about when.
The difference between basic first aid and professional medical cover can be measured in minutes – and those minutes can mean everything.
Your choice of medical provider is ultimately a choice about the level of risk you’re willing to accept.

Frequently Asked Questions

How common are serious medical emergencies at events? Serious emergencies requiring hospital treatment occur at roughly 0.1-0.3% of large events. That means a 5,000-person event might see 5-15 serious cases.
What’s the most common serious emergency you see? Cardiac events, drug-related emergencies, and serious trauma from falls or crowd incidents are the most frequent serious presentations.
How do you decide when to call an ambulance vs treating on-site? Our senior clinicians make these decisions based on clinical assessment, patient stability, and treatment requirements. We can often provide definitive treatment on-site for many conditions.
