Roughly 28,000 people in England are resuscitated from out-of-hospital cardiac arrest each year, and in the overwhelming majority of those cases the first person to act is not a paramedic but a bystander or a trained volunteer. Basic life support training — the short, standardised course that teaches chest compressions, rescue breaths, and defibrillator use — is what turns an ordinary member of the public into someone capable of buying a patient the minutes they need before an ambulance arrives. In London, that training underpins the network of Community First Responder schemes that ambulance services rely on to close the gap between a 999 call and professional care.
This review exists to document what actually strengthens frontline health infrastructure across the capital, in the spirit of the original "Better Health for London" inquiry’s focus on prevention and the wider chain of care. Community resuscitation is a clear example: a low-cost, volunteer-driven layer of the system with a well-documented evidence base behind it.
What a Community First Responder Scheme Actually Does
Community First Responders (CFRs) are volunteers, coordinated by their local ambulance service, who are dispatched to nearby medical emergencies — most often suspected cardiac arrests, chest pain, choking, stroke, or serious falls — and arrive ahead of, or alongside, the ambulance crew. Most ambulance services state plainly that no prior medical background is required to join; the scheme’s own training is the qualification. Responders carry an automated external defibrillator, oxygen and basic airway equipment, and a mobile dispatch device that alerts them when a call comes in close to their location.
A parallel layer runs through the GoodSAM app, a dispatch platform used by ambulance services including the NHS in the UK. GoodSAM Cardiac alerts nearby trained responders — off-duty paramedics, nurses, doctors, and members of the public who have completed CPR training — the moment a cardiac arrest call comes in, on the basis that the closest trained person, not the closest ambulance, is usually the one who can start compressions first.
How Volunteers Get Their Basic Life Support Training
The training pathway is deliberately accessible. Resuscitation Council UK partners with GoodSAM to offer a free route in: its Lifesaver course, an interactive video-game-style module, teaches core CPR and defibrillator skills, after which a member of the public can register as a GoodSAM cardiac responder. The British Heart Foundation runs a parallel public-education initiative, Heartstart UK, teaching the same emergency life support skills to community groups, schools, and workplaces.
Formal Community First Responders go further. London Ambulance Service, for example, requires new CFRs to complete a five-day accredited course covering basic life support and defibrillation alongside patient assessment, airway management, and the recognition of common medical emergencies such as choking, stroke, and allergic reaction. Other ambulance trusts run comparable regulated courses. All require mandatory annual refreshers and ongoing e-learning, because resuscitation skills are known to decay without regular practice — a detail that matters as much as the initial course itself.
Does Bystander CPR and CFR Coverage Actually Improve Survival?
The evidence on bystander CPR itself is consistent and strong: observational studies suggest it can increase survival from cardiac arrest by two to four times, and survival odds fall by roughly 10% for every minute that passes without compressions or defibrillation. That arithmetic is why the "chain of survival" model treats the minutes before an ambulance arrives as the most decisive part of the whole emergency, not a waiting period before the real care begins.
National figures put that gap in context. Around 80% of out-of-hospital cardiac arrests happen in the home and only about 13% in public spaces, yet public-access defibrillators are used in fewer than one in ten cases even though over 70% of patients now receive some bystander CPR. Survival to hospital discharge in England sat at 7–8% between 2011 and 2014, and the more recent Out-of-Hospital Cardiac Arrest Outcomes registry, funded jointly by Resuscitation Council UK and the British Heart Foundation, found that fewer than one in twelve patients (7.8%) survive to 30 days. One regional service, South East Coast Ambulance Service, reported bystander CPR attempted in 79% of cases in 2022–23 and a 30-day survival rate of 9.5%, above the national average; where a defibrillator was used before the ambulance arrived, shock delivery came over four minutes sooner, and every patient successfully resuscitated by that earlier shock survived at least 30 days.
The role of formal CFR schemes specifically is more nuanced than the bystander-CPR headline figures suggest. Research reviewed by the National Institute for Health and Care Research found that while Community First Responders reliably improve prehospital response times and help ambulance services meet response targets, that faster arrival did not, on its own, translate into a measurable increase in survival from out-of-hospital cardiac arrest. The honest reading is that CFRs are one contributor to a system where bystander CPR and early defibrillation — whoever delivers them — are what actually change outcomes, and a well-trained volunteer network raises the odds that someone competent is on scene sooner.
The Chain of Survival, Link by Link
| Link | Typical actor | What it changes |
|---|---|---|
| Early recognition and 999 call | Bystander or family member | Starts the response clock; every minute of delay costs survival odds |
| Early bystander CPR | Untrained or briefly-trained public, CFR, or GoodSAM responder | Can double to quadruple survival odds versus no CPR |
| Early defibrillation | Public-access AED, CFR-carried AED, or ambulance crew | Shock delivered minutes sooner shows measurably better outcomes |
| Early advanced life support | Paramedics and hospital emergency teams | Stabilises and treats the underlying cause after return of circulation |
Why This Matters Across London’s Boroughs
Because the evidence points so clearly to the minutes before the ambulance arrives, the practical question for any city is not just how many paramedics it employs but how many of its residents can competently start compressions and reach for a defibrillator. Basic life support training, delivered at scale through free platforms like Resuscitation Council UK’s Lifesaver course, workplace and school programmes such as Heartstart UK, and formal Community First Responder schemes coordinated by London Ambulance Service, is the mechanism by which that capability gets distributed across a population rather than concentrated in a small number of professionals. As with the wider chain of survival, the return on this kind of low-cost, volunteer-based training tends to be judged less by any single statistic and more by how consistently it shows up, borough by borough, in the minutes that matter most.
