Hospital preparedness and clinical description of the 2009 influenza A (H1N1) pandemic in a Belgian tertiary hospital

We describe hospital preparedness, including costs, and clinical characteristics of the 2009 influenza A (H1N1) pandemic in adult patients in a Belgian tertiary care centre. A task force coordinated the overall management, including triage and hospitalisation. Between 1 June and 30 November 2009, 521 patients with influenza-like illness were admitted to the emergency ward. We reviewed data from 43 hospitalised patients with confirmed influenza A. Median age was 44 years (range: 21-79), with 84% patients having underlying disease. Eleven needed admission to intensive care unit (ICU) and one patient died. The financial impact of the epidemic was estimated at (sic)75,691, and approximately half of these costs were related to the enhanced infection control practices. The Belgian 2009 influenza A (H1N1) pandemic, as described in a cohort of 43 hospitalised patients, was associated with a relatively high ICU admission rate of 26% and a fairly typical mortality rate of 3%. This retrospective study may help us refine the management of future epidemics. (C) 2010 The Hospital Infection Society. Published by Elsevier Ltd. All rights reserved.
