Factors affecting health care utilization for children in Japan

Abstract

Background and objective: Studies on the ecology of medical care for children have been reported only from the United States. Our objective was to describe proportions of children receiving care in 6 types of health care utilization seeking behaviors in Japan on a monthly basis and to identify care characteristics.

Methods: A population-weighted random sample from a nationally representative panel of households was used to estimate the number of health-related symptoms, over-the-counter medicine doses, and health care utilizations per 1000 Japanese children per month. Variations in terms of age, gender, socioeconomic status, and residence location were also examined.

Results: Based on 1286 households (3477 persons including 1024 children) surveyed, on average per 1000 children, 872 had at least 1 symptom, 335 visited a physician's office, 82 a hospital-based outpatient clinic, 21 a hospital emergency department, and 2 a university-based outpatient clinic. Two were hospitalized, and 4 received professional health care in their home. Children had 2 times more physician visits and 3 times more emergency visits than adults in Japan, and Japanese children had 2.5 times more physician visits and 11 times more hospital-based outpatient clinic visits than US children. Pediatric health care utilization is influenced significantly by age but not affected by income or residence location in Japan.

Conclusions: Compared with the data from the United States, more children in Japan visit community physicians and hospital-based outpatient clinics. Results of this study would be useful for further delineation of health care utilization of children in the context of a health care system unique to Japan.
