Abstract
Objective To assess the impact of rotavirus gastroenteritis on young children attending a paediatric hospital, their families and the health care system. Design Cross‐sectional descriptive survey. Setting New Children's Hospital (Royal Alexandra Hospital for Children), Sydney, New South Wales, 15 July to 4 October 1996. Participants Children aged under three years attending the Emergency Department with acute diarrhoea as the presenting symptom. Outcome measures Cases of rotavirus infection confirmed by enzyme‐linked immunosorbent assay by age; rotavirus serotype; gastroenteritis severity score; estimated costs to parents (lost pay or leave, travel, medication and other expenses) and to the health care system (visits to Emergency Department and other health care workers, hospital admissions). Results 280 children were recruited (73% of 384 children who met the inclusion criteria and 27% of the 1037 aged under three years with acute gastroenteritis). Rotavirus was detected in 188 of the 280 (67%); most isolates were serotype G1 (86% of the 174 serotyped). Of the 188 children with confirmed rotavirus infection 78% were aged 7‐24 months and 82% visited at least one other health care worker, usually a general practitioner. Seventy (37% of the 188) were admitted to hospital; 33 of these (47%) were aged 13‐24 months. Estimated mean total cost per episode of rotavirus gastroenteritis was $1744 for children admitted to hospital and $441 for children not admitted. The mean cost to families was $493 for children admitted to hospital and $228 for children not admitted. Conclusions Rotavirus gastroenteritis has a significant impact on young children, their families and the health care system. Prevention of severe disease through routine infant vaccination would be potentially cost‐effective.
