BACKGROUND
Varicella is a common, highly contagious disease. It is usually benign but has potentially serious complications.
METHODS
To assess the clinical characteristics and the associated cost of varicella hospitalization, we reviewed the medical records of children hospitalized for varicella between 2001 and 2004. Children with coincidental varicella hospitalized for a different reason were excluded.
RESULTS
Of 1177 children with varicella attended at the emergency room, 101 (8.6 %) were hospitalized. The median age was 3.2 years (21 days to 18.9 years). Twenty-eight children had underlying disease. Thirty-seven children had no complications and the reason for admission was: a) risk of severe varicella (21 immunocompromised children, three neonates), and b) high fever or observation (13 cases). The 64 remaining children were admitted for 66 complications of varicella. The most common complications were skin/soft tissue infections (33 patients) and the leading cause was Streptococcus pyogenes (n = 13) and Staphylococcus aureus (n = 10) isolated in blood or the site of infection. Other complications were pneumonia (13 children), neurological (febrile seizures in nine, meningoencephalitis in two, acute disseminated encephalomyelitis in one, cerebellitis in one), hematological (neutropenia in one, Henoch-Schönlein purpura in one and thrombopenic purpura in three) and osteoarticular (synovitis in one and septic arthritis in one). One patient died of multiorgan failure. During the study period, the rate of emergency room visits due to varicella doubled and the number of admissions for complications tripled. The mean length of hospital stay was 6.8 days (range: 1-28 days) and the total associated cost was 397,314.14 Euro, excluding symptomatic treatment.
CONCLUSIONS
The high morbidity associated with varicella and its complications, as well as the high social costs of this disease, support the implementation of routine varicella vaccination. This could reduce the total number of cases, their severity, direct costs, generated by medical care, and indirect costs, generated by the disease and hospitalization.
