Hospitals Face Severe Disruption From Swine Flu

NEW YORK (ASRN.ORG)- Swine flu may hospitalize 1.8 million patients in the U.S. this year, filling intensive care units to capacity and causing “severe disruptions” during a fall resurgence, scientific advisers to the White House warned. 

Swine flu, also known as H1N1, may infect as much as half of the population and kill 30,000 to 90,000 people, double the deaths caused by the typical seasonal flu, according to the planning scenario issued by the President’s Council of Advisers on Science and Technology. Intensive care units in hospitals, some of which use 80 percent of their space in normal operation, may need every bed for flu cases. 

The virus has sickened more than 1 million people in the U.S., and infections may increase this month as pupils return to school. “If swine flu patients fill too many beds, hospitals may be forced to put off elective surgeries such as heart bypass or hernia operations,” said James Bentley with the American Hospital Association. 

“If you have 1.8 million hospital admissions across six months, that’s a whole lot different than if you have it across six weeks,” said Bentley.

The scenario projections were “developed from models put together for planning purposes only,” said Tom Skinner, a spokesman for the CDC. “At the end of the day, we simply don’t know what this upcoming flu season is going to look like. It could be severe, it could be mild, we just don’t know.”

Past Pandemics

The models were based on past pandemics, and the CDC is working on new projections based on the latest data gathered from swine flu patients, Skinner said. Those estimates should be available “soon,” he said, without further specifying. 

President Barack Obama was urged by his scientific advisory council to speed vaccine production as the best way to ease the burden on the health care system. Initial doses should be accelerated to mid-September to provide shots for as many as 40 million people. Members also recommended Obama name a senior member of the White House staff, preferably the homeland security adviser, to take responsibility for decision-making on the pandemic. 

“This isn’t the flu that we’re used to,” said Kathleen Sebelius, U.S. health and human services secretary. “The 2009 H1N1 virus will cause a more serious threat this fall. We won’t know until we’re in the middle of the flu season how serious the threat is, but because it’s a new strain, it’s likely to infect more people than usual.”

Clinical Trials 

Data from clinical trials to assess the safety and effectiveness of swine flu vaccines will start to become available in mid-September. Full results from the two-dose trials won’t be available until mid-October. 

“We are making every preparation effort assuming a safe and effective vaccine will be available in mid-October,” Sebelius said today at the CDC’s Atlanta offices. 

H1N1 has already reached more than 170 countries and territories in the four months since being identified. Swine flu causes similar symptoms as seasonal strains. It has so far resulted in worse than normal flu seasons, with increased hospitalizations and cases of severe illness. 

New Zealand and Australia, in the midst of their normal flu seasons, have reported intensive care units taxed to capacity by swine flu patients. The experience provides clues to what the U.S., Europe and Japan may see when the H1N1 virus returns.

President’s Advisers 

The president’s advisory council describes as a “plausible scenario,” that 30 percent to 50 percent of the U.S. population will be infected in the fall and winter. As many as 300,000 patients may be treated in hospital intensive care units, filling 50 percent to 100 percent of the available beds, and 30,000 to 90,000 people may die. 

“This is a planning scenario, not a prediction,” according to the report. “But the scenario illustrates that an H1N1 resurgence could cause serious disruption of social and medical capacities in our country in the coming months.” 

Peter Gross, chief medical officer at Hackensack University Medical Center, said if the group’s scenario comes true, “I think every hospital in America is going to be in a crunch. We’ll be hard pressed to deal with those predictions,” he said. 

‘Overblown’ Estimates 

The estimates seem “overblown,” Gross said, given that swine-flu outbreaks in 1968 and 1957 failed to cause as many deaths, even with medical technology and disease surveillance less advanced than today.

“Influenza, you can make all the predictions you want, but it’s more difficult than predicting the weather,” Gross said. “If influenza was a stock, I wouldn’t touch it.” 

The 775-bed hospital is planning for an outbreak, upping its order of flu medications and discussing where to put patients if the worst occurs, Gross said. 

New Estimates 

Seasonal flu usually kills about 36,000 Americans. Swine flu causes more severe illness needing hospitalization among younger people than seasonal flu, while leaving people 65 and older relatively unscathed. 

The median age of those with the pandemic virus has been 12 to 17 years. 

Disease Burden 

About 100 million people in the U.S. get the annual flu shot. Pregnant women, who have “a disturbingly high burden of disease” from swine flu, only get vaccinated for seasonal flu about 15 percent of the time. Pregnant women are a top priority for vaccinations. 

Seasonal flu usually kills about 36,000 Americans. Swine flu causes more severe illness needing hospitalization among younger people than seasonal flu, while leaving people 65 and older relatively unscathed. 

“People who get infected with this strain happen to be the healthiest members of our society,” 

The H1N1 strain is genetically related to the 1918 Spanish Flu that killed an estimated 50 million people. Variations of the Spanish Flu circulated widely until about 1957, when they were pushed aside by other flu strains. People whose first exposure to a flu virus was one of those Spanish Flu relatives may have greater immunity to the current pandemic.
