ALBUQUERQUE, N.M. — A veteran who collapsed in an Albuquerque Veteran Affairs hospital cafeteria — 500 yards from the emergency room — died after waiting 30 minutes for an ambulance, officials confirmed Thursday.

It took a half an hour for the ambulance to be dispatched and take the man from one building to the other, which is about a five-minute walk, officials at the hospital said.

Kirtland Air Force Medical Group personnel performed CPR until the ambulance arrived, VA spokesman Sonja Brown said.

Staff followed policy in calling 911 when the man collapsed on Monday, she said. “Our policy is under expedited review,” Brown said.

News of the man’s death spread Thursday at the Raymond G. Murphy VA Medical Center among veterans who were visiting for various medical reasons.

Lorenzo Calbert, 65, a U.S. Army veteran of the Vietnam War, said it was sad that a fellow veteran had to die so close to where he could have received help.

“There’s no reason for it,” he said. “They have so many workers. They could have put him on the gurney and run faster than that ambulance.”

Paul Bronston, a California emergency-room physician and chair of Ethics and Professional Policy Committee of the American College of Medical Quality, said it may sound ridiculous that staff had to call 911 but that practice is the standard at hospitals. Typically, an ambulance would arrive faster, and other factors can stall workers trying to rush patients to the emergency room on foot, he said.

“The question I would have (is) ... was there an AED (automated external defibrillator) on site as required?” he said. Bronston said 90 percent of those who collapse are afflicted by heart problems and an AED could help them.

It was not known what caused the man to collapse or whether an AED was nearby.

The death comes as the Department of Veterans Affairs remains under scrutiny for widespread reports of long delays for treatment and medical appointments and of veterans dying while on waiting lists.

A review last week cited “significant and chronic system failures” in the nation’s health system for veterans. The review also portrayed the struggling agency as one battling a corrosive culture of distrust, lacking in resources and ill-prepared to deal with an influx of new and older veterans with a range of medical and mental health care needs.

The scathing report by Deputy White House Chief of staff Rob Nabors said the Veterans Health Administration, the VA sub agency that provides health care to about 8.8 million veterans a year, has systematically ignored warnings about its deficiencies and must be fundamentally restructured.
