An intensive care unit nurse in a small-town hospital on the Eastern Shore suspected that a patient had necrotizing fasciitis, the so-called "flesh-eating" disease.
The condition is rare. Even experienced intensive-care doctors seldom see it, and, since it was nighttime, no such physician was in the ICU. Pinning down the diagnosis was critical — and in this case Berlin's Atlantic General Hospital had backup.
A critical-care doctor 125 miles away was monitoring the patient's health via voice, video and high-speed data lines constantly streaming information about vital signs, medications, test results and X-rays, a telemedicine service known as University of Maryland eCare. The physician quickly verified that the patient had the deadly infection and arranged immediate transfer to another hospital with a surgeon who could remove the infected tissue.
Atlantic General is one of University of Maryland eCare's six original community hospital clients, which have a total of 72 ICU beds. At the end of last year, the program went live in three more Eastern Shore hospitals, adding 20 more ICU beds.
Studies have shown that patients do better and leave sooner from ICUs managed by intensivists, another term for critical-care doctors. But intensivists are in short supply nationwide, and small community hospitals like Atlantic General have a difficult time recruiting and retaining them, let alone paying their salaries. Connecting intensivists to small ICUs via telemedicine, proponents say, is the next best thing to hiring them.
Telemedicine, the exchange of medical information between sites via electronic communications, is being used not only by ICUs but by other hospital departments, home health agencies and private doctors' offices. But skeptics suggest that small ICUs might be able to improve care with less expensive measures. Telemedicine now costs hospitals roughly $40,000 to $50,000 a year for each covered bed. Initially, adaptation of telemedicine in ICUs nationwide was rapid, but a new study suggests it is slowing.
One of UM eCare's 20 intensivists monitors ICU patients from 7 p.m. to 7 a.m. weeknights and for 24 hours on Saturdays and Sundays. They're stationed at computers in eCare's COR — Central Operations Room — in the University of Maryland Medical Center. On weekdays, when the hospitals' critical care doctors are at work, eCare critical care nurses staff the COR computers.
Critical care specialist Atif Zeeshan and another intensivist work in Atlantic General's ICU from 7 a.m. to 7 p.m. on alternating weeks, and they're on call 24/7. Zeeshan said he was at first leery of telemedicine. Four years after his eight-bed ICU hooked up with eCare, Zeeshan is a believer. "There have been cases where lives were saved with eCare intervention," he said.
CareFirst BlueCross BlueShield helped establish eCare with a $3 million grant for capital expenses, such as computer and video connections. Participating hospitals pay an annual fee for each ICU bed. Other clients include Peninsula Regional Medical Center in Salisbury, Union Hospital in Elkton, Meritus Medical Center in Hagerstown, Calvert Memorial Hospital in Prince Frederick, MedStar St. Mary's Hospital in Leonardtown and UM Shore Medical Centers at Easton, Dorchester and Chestertown.
Zeeshan's initial skepticism isn't unusual.
"Nobody wants to be dictated to," acknowledged Marc Zubrow, a critical-care and lung specialist and University of Maryland eCare's medical director. "An absolutely huge part of my job," said Zubrow, is to "convince the local medical community that this will not negatively impact patient care and might possibly improve patient care."
Hospital representatives routinely visit the Baltimore COR, and Zubrow and members of his team regularly visit the community hospitals and "get very close with the local bedside people."
And sometimes to patients' families. Zubrow shared an eCare doctor's notes about an interaction with a patient's daughter (stripped of information that could have identified the patient). The woman, who'd flown in to be at her critically ill mother's bedside, arrived around 3 a.m. and spent a few minutes video-chatting with the eCare intensivist on duty.
"I told her that nothing we do medically is going to improve her mother's condition or meaningfully prolong her life," according to the doctor's notes. "I urged her to allow us to focus on treating her mother's pain and suffering. …I offered my support and told her I would speak with her again at any point tonight."
Community hospitals say telemedicine helps critically ill patients be treated close to home and family. Even with extra oversight, however, these hospitals still are not equipped to care for all critically ill patients, so telemedicine intensivists help them decide which patients should be transferred.
But Jeremy Kahn is skeptical. An associate professor of critical care, medicine and health policy at the University of Pittsburgh, he said assessing telemedicine's effectiveness in the ICU is tricky. Comparing mortality rates before and after implementation of telemedicine doesn't account for the fact that "outcomes in the ICU get better over time, no matter what," Kahn said.
A better comparison would be to other, less expensive, measures, such as using more non-physician providers — physician assistants and nurse practitioners — at ICU patients' bedsides, Kahn said.
While UM eCare is adding hospitals, Kahn said adoption of telemedicine in ICUs nationwide is slowing down. In a study published online in October by Critical Care Medicine, Kahn and his colleagues found that the number of U.S. hospitals using telemedicine in ICUs increased from 16, or 0.4 percent, in 2003, to 213, or 4.6 percent, in 2010, with usage doubling in the first four years but dropping to average growth of 8.1 percent in the last four.
"In an era of cost constraints, I feel we need to be simultaneously exploring cheaper ways to get the same outcome," Kahn said. "That's not to say we should not explore telemedicine."
