The increasing use of pediatric emergency facilities in the evening.

OBJECTIVES

In Japan, the demand for pediatric emergency medicine has been increasing, especially in the evening. The purpose of this study was to identify the reasons for overcrowding of pediatric emergency facilities in the evening.

METHODS

A population-based survey was conducted in Yokohama City, Japan, that targeted parents of children 1 or 3 years of age. These children participate in regular health checkups. Questionnaires about their child's illnesses and the pediatric emergency system were mailed to 30,000 parents of a child expected to undergo a health checkup between May 2004 and January 2005.

RESULTS

Data obtained from the completed questionnaires indicated that many parents noticed their child's illness or injury most frequently during the evening, when most medical facilities are closed. The peak period when parents noticed their child's illness was the evening (4:00 pm-12 midnight, 54.4%), followed by the daytime (8:00 am-4:00 pm, 30.3%) and then the nighttime (12 midnight-8:00 am, 15.3%). During all 3 periods, parents felt it difficult to judge their child's condition and thus many used emergency facilities unnecessarily.

CONCLUSIONS

The overcrowding of pediatric emergency facilities in the evening is likely due mainly to a mismatch between the peak time of children's illnesses and the office hours of pediatric clinics. Parents' difficulties in assessing their child's condition and anxiety over their child's illness and injuries seem to be other factors that contribute to this imbalance.
