NHS National Institute of Health Research -
The role of ambulance services has changed over the last few decades with the introduction of paramedics able to provide life-saving interventions, thanks to sophisticated equipment and treatments available. The number of 999 calls continues to increase, with adverse events theoretically possible with each one. Most patient safety research is based on hospital data, but little is known concerning patient safety when using ambulance services, when things can be very different. The objective of this research was to identify and map available evidence relating to patient safety when using ambulance services.
