Princess Diana's Death: Anniversary Brings French Health Care Into Focus - ABC News

Diana's last hour -- in cardiac arrest and bleeding to death -- was spent in a mobile medical unit parked a few hundred yards from Pitié-Salpêtrière Hospital, where an emergency team followed French protocol and administered treatment at the scene of the accident and en route to the hospital.

At the time, many people surmised that had a U.S. ambulance responded, Diana would have been rushed to the nearest emergency room, where a full set of professionals and diagnostic equipment might have revived her.

Colloquially known as "scoop and run," the U.S. system is grounded in studies that show a trauma victim's best chance for survival is reaching the operating room within 10 minutes.

Under the French system, "stay and play," a fully equipped medical ambulance with a doctor stabilizes the patient and then directs him or her to a specialized hospital, even if it is miles away.
