A Midland ambulance service boss is to address delegates from across the world at a major conference in the United States this week on emergency medical systems.
Roger Thayne, chief executive of Staffordshire Ambulance Service, is being flown out by event organ-isers to the Coalition of Advanced Emergency Medical Systems Conference in Reno, Nevada.
The trust's chairman, Robert Lake, said the invitation was a direct result of the "regard and reputation held by Staffordshire Ambulance Service around the world".
He said: "Led by its chief executive Roger Thayne, it has taken the concept of the high performance system, adopted, adapted and refined its operation, to achieve its present success in providing the most cost-effective and recordbreaking life-saving service for the public than any other comparable ambulance service in the world."
Delegates are funding all Mr Thayne's expenses.
A trust spokesman added: "It is puzzling that with such recognition and accolades from outside the NHS ambulance sector, but in light of the proposals for future ambulance service provision, an old adage may apply to Roger: 'a prophet is without honour in his own country'."
