Abstract

Objective: To estimate the incidence of influenza infection with a rapid diagnostic test in patients hospitalized in an intensive care unit (ICU) during the epidemic periods of two consecutive winters (2005-2006). Methods: This study tested nasal aspirate of all patients admitted to the ICU for acute respiratory failure during the influenza epidemic period with the QuickVue® influenza rapid diagnostic test. Results: The study included 39 patients: 22 men and 17 women. Their mean age was 69.7 ± 13 years, their mean SAPS II score 54 ± 21, their mean length of stay 14.7 ± 20 days, and 43.5% had been vaccinated against influenza. The mortality rate was 33.3% (n = 13). Four patients (10.2%) had a positive QuickVue test and were considered to have influenza associated with their primary diagnosis: pneumococcal pneumonia, haemophilus pneumonia, acute bronchitis, and acute bronchitis with acute cardiogenic edema. These patients were older than those with a negative test (80 ± 7 versus 68 ± 13 years, p = 0.02). Their SAPS II, length of stay and mortality rate did not differ statistically from those with negative results. Chronic heart failure (but not COPD or non-vaccination) was more frequent in these patients (p = 0.01). Discussion: Several published studies report a satisfactory specificity and sensitivity for QuickVue®. With this test, we estimated the incidence of influenza in patients hospitalized in our ICU for acute respiratory failure during flu epidemics at around 10%, close to that reported in previous studies.{A textbox is presented}.
