Our objective was to describe respiratory disease hospitalizations among children in a community of Seoul, Republic of Korea. Discharge data (January 1995-December 2005) from Guro Hospital (Seoul, Republic of Korea) were collected from the hospital medical records office. Respiratory virus test results (March 2004-December 2005) and hospitalization charges to the National Health Insurance Corporation (January 2002-December 2005) were provided by hospital laboratory and administrative departments. Variations in hospitalizations, test results and total hospitalization-associated medical charges were described by age, clinical complaint, discharge month and length of stay. Over the 11-y period, 4247 paediatric hospitalizations for lower respiratory disease occurred. Semi-annual epidemics were identified in October-December and April-May. Among a subset (n=400) of patients, 48% had respiratory syncytial virus, 16% parainfluenza virus, 19% influenza viruses and 17% adenovirus infection. On admission, children had respiratory problems (53%), fever (39%), or other systemic problems (8%). The median charge of a lower respiratory disease hospitalization was highest in January ($1334) and lowest in October ($1076). Median hospitalization charges were highest among children 8-15 years of age compared with younger children
