Background: While recent advances in asthma management have enabled adequate control to be frequently achieved in outpatient settings, children whose asthma remains poorly controlled despite outpatient treatment are often referred to extended-stay hospitals. The aim of the present study was to examine trends concerning extended-stay hospitalization and to evaluate the present status of this approach.
Methods: A retrospective study was conducted to assess changes in the number of admissions among 408 children with extended stays at Kamiamakusa General Hospital between 1989 and 2005.
