Flu confirmations in hospital respiratory patients soared during pandemic
An influenza diagnosis was confirmed far more often in patients hospitalized for respiratory illness in Canada during the 2009 H1N1 flu pandemic than during the preceding 6 years, according to a report published today in Influenza and Other Respiratory Viruses. The researchers, from Ottawa and Toronto, note that the number of hospital admissions in which flu is confirmed is considered much lower than the true number of hospital cases caused by flu. The team examined the Canadian Discharge Abstract Database for April 2003 through March 2010 for information on all patients admitted with any respiratory condition. For the years preceding the pandemic—April 2003 through April 2009—they estimated that flu was confirmed in only 1 of every 6.4 admissions attributed to seasonal flu. But during the pandemic—May 2009 through March 2010—they estimated that flu was confirmed in 1 of every 1.6 admissions attributed to the pandemic virus. "Case ascertainment was much improved during the pandemic period, with under ascertainment of admissions due to H1N1/2009 limited primarily to patients with a diagnosis of pneumonia," the report says.
