Event Medical Cover Calculator

Plan safer events with a clearer understanding of your medical needs

No two events carry exactly the same risks. Attendance, venue type, audience profile, activities, location and access to local healthcare can all affect the level of medical provision required.

The Rapid EMS Event Medical Cover Calculator provides an initial indication of the people, vehicles and facilities that may need to be considered when planning your event.

It uses a recognised event-risk scoring approach to help you begin the planning process. The result should be treated as guidance rather than a final specification.

Why medical planning matters

Effective event medical cover involves more than placing a first aider or ambulance at the venue. Organisers need to consider:

  • The number and type of people attending
  • Activities that could cause illness or injury
  • Alcohol and recreational drug use
  • Previous casualty data
  • How long the event will last
  • Queuing and overnight attendance
  • Travel time to the nearest emergency department
  • Suitable facilities for assessing and treating patients
  • How patients would be transported if further care were required

The Health and Safety Executive recommends including members of the public—not only employees—in an event’s first-aid, medical and ambulance needs assessment. Organisers should also consider how emergency services will be contacted and how patients would be transferred to hospital.

Ambulance provision and CQC registration

In England, providers carrying out regulated ambulance transport or treatment activities may need to be registered with the Care Quality Commission. CQC guidance explains that transporting a patient within an event site is treated differently from transporting that person away from the event or to hospital. The vehicles being used, the destination and any treatment provided during transport can all affect the registration requirements. When comparing medical providers, organisers should confirm that each provider holds the registrations appropriate to the services being offered. Check the latest CQC guidance for ambulance services. View Rapid EMS on the CQC website.

On-site treatment and patient transport

An ambulance may form an important part of an event medical plan, but it should not automatically be treated as the event’s only clinical facility. Depending on the size and risk profile of the event, the medical plan may need to include a dedicated first-aid post, treatment area or medical centre. This provides an appropriate place to assess and care for patients while helping ensure that transport resources remain available when required. If an ambulance leaves the venue with a patient, the remaining medical provision must still be sufficient to maintain safe cover.

Understanding event tiers

The tier descriptions below offer a broader way to think about event complexity. Attendance is only one consideration: a smaller event with hazardous activities or a higher-risk audience may require more support than a larger, lower-risk gathering.

Tier 1:
Small, straightforward events

Tier 1 generally covers short, low-risk events at which serious illness, injury or hospital transfer is unlikely.

Typical characteristics may include:

  • A duration of a few hours
  • Fewer than 500 attendees
  • Low-risk activities
  • Little or no alcohol consumption
  • Little likelihood of recreational drug use
  • A very low probability of hospital referral
  • Depending on the medical needs assessment, appropriate arrangements may include a suitable first-aid kit, someone competent to use it, access to a defibrillator and a clear procedure for contacting emergency services.

Tier 2:
Lower-risk events requiring dedicated first aid

Tier 2 events are often larger or longer than Tier 1 events and may fall within local-authority licensing arrangements.

Typical characteristics may include:

  • A duration of several hours or up to one day
  • Up to approximately 2,000 attendees
  • Activities presenting a relatively low risk of illness or injury
  • Social alcohol consumption
  • Hospital transfer remaining unlikely
  • Provision may include a dedicated first-aid resource, an appointed medical lead, trained first responders and healthcare professionals. An appropriately crewed ambulance may be required where transfers are reasonably foreseeable.

Tier 3:
Events with a foreseeable clinical demand

Tier 3 events normally present a moderate level of risk and require a dedicated medical operation.

Typical characteristics may include:

  • An event lasting longer than one day
  • Up to approximately 5,000 attendees
  • Activities with a moderate risk of injury or illness
  • A realistic likelihood of alcohol or drug-related presentations
  • Foreseeable referrals to hospital

Provision may include an experienced clinical lead, registered healthcare professionals, first responders, treatment facilities and suitably crewed ambulances.

Tier 4:
Large or complex events

Tier 4 covers events where the scale, duration or activities are likely to produce a significant medical workload.

Typical characteristics may include:

  • A duration of one or more days
  • Up to approximately 10,000 attendees
  • Activities carrying a significant risk of injury or illness
  • Expected alcohol or drug-related presentations
  • A likelihood that some patients will require hospital care
  • These events will normally require a structured medical operation led by an experienced registered healthcare professional. Resources may include doctors, nurses, paramedics, first responders, ambulances, treatment facilities and supporting command arrangements.

Tier 5:
Major or particularly high-risk events

Tier 5 includes mass gatherings and smaller events whose activities or audience profile create unusually high risks.

Typical characteristics may include:

  • More than 10,000 attendees
  • An event lasting several days
  • High-risk activities
  • Significant anticipated alcohol or drug-related demand
  • Expected hospital transfers
  • Complex operational or logistical requirements

A comprehensive medical service is normally required. This may include a senior clinical lead, multidisciplinary healthcare teams, first responders, multiple ambulances, dedicated treatment facilities and medical control personnel.

Your calculator result is a starting point

A numerical score cannot capture every feature of an event. Weather, site layout, crowd movement, safeguarding requirements, emergency access, local hospital capacity and previous event data may all change the final recommendation.

The level of cover should ultimately be determined through a documented medical needs assessment. That assessment can then inform a detailed medical plan covering staffing, equipment, facilities, communications, patient records, emergency procedures and hospital transport.

1. Describe your event

Select the options that best reflect the event, venue, audience, expected attendance and surrounding healthcare provision.

2. Review the risk score

Your score updates as you make selections. Additional hazards increase the score, while certain on-site clinical facilities may reduce it.

3. View the indicative provision

The result provides a starting point for considering first responders, healthcare professionals, ambulances and supporting resources.

4. Arrange a professional assessment

The calculator cannot account for every factor. Rapid EMS can review the event in more detail and prepare an assessment and operational medical plan.
