BACKGROUND: @entity683 infections can lead to @entity5131 , @entity1729 or facilitate co- @entity281 by other pathogens. @entity683 is associated with the exacerbation of chronic conditions like @entity6 and @entity65 and consequently, these result in acute hospitalizations. This study estimated the number, proportions and costs from a payer perspective of hospital admissions related to severe @entity1729 . METHODS: We analyzed retrospectively, a database of all acute inpatient stays from a non-random sample of eleven hospitals using the Belgian Minimal Hospital Summary Data. Codes from the International Classification of Diseases, Ninth Revision, Clinical Modification was used to identify and diagnose cases of @entity55 and @entity683 (PI), respiratory and circulatory (RC), and the related complications. RESULTS: During 2002-2007, we estimated relative hospital admission rates of 1.69% (20960/1237517) and 21.79% (269634/1237517) due to primary PI and RC, respectively. The highest numbers of hospital admissions with primary diagnosis as PI were reported for the elderly @entity1 group (n   =   10184) followed by for @entity1 below five years of age (n   =   3451). Of the total primary PI and RC hospital admissions, 56.14% (11768/20960) and 63.48% (171172/269634) of cases had at least one possible @entity683 -related complication with the highest incidence of complications reported for the elderly @entity1 group. Overall mortality rate in @entity1 with PI and RC were 9.25% (1938/20960) and 5.51% (14859/269634), respectively. Average lengths of hospital stay for PI was 11.6        12.3  days whereas for RC it was 9.1        12.7  days. Annual average costs were 20.2 and 274.6 million @entity7634 for PI and RC hospitalizations. Average cost per hospitalization for PI and RC were 5779 and 6111 @entity7634 (2007), respectively. These costs increased with the presence of complications (PI: 7159, RC: 7549 @entity7634 ). CONCLUSION: The clinical and economic burden of primary @entity683 hospitalizations in Belgium is substantial. The elderly @entity1 group together with @entity1 aged <18  years were attributed with the majority of all primary PI and RC hospitalizations. TRIAL REGISTRATION: Not applicable.
