Estimation of the number of children with cerebral palsy using nationwide health insurance claims data in Japan

Abstract

Our estimation of CP prevalence per 1000 population at age 5 to 9 years lay in the higher range of figures from previous studies in Japan, and was close to figures reported by European countries.

Cesarean section rates and local resources for perinatal care in Japan: A nationwide ecological study using the national database of health insurance claims

“…The use of the JNDB is a practical and inexpensive approach for estimating basic national statistics. 44,45 Our study has some limitations. First, prefectural CS rates might have been different from true CS rates because the number of births based on newborn residence was used as a denominator.…”

“…Further, the calculated number of CS performed in September and the the number based on existing triennial government data were similar (16 100 in the present data of 2013 and 16 797 in existing data of 2014), suggesting that both our data and the existing triennial data are a reliable reflection of the true CS rate in Japan. The use of the JNDB is a practical and inexpensive approach for estimating basic national statistics …”

Preoperative oral care and effect on postoperative complications after major cancer surgery

“…This was a retrospective observational cohort study carried out using data from the National Database of Health Insurance Claims in Japan. The details of this database have been described elsewhere. Briefly, it is an all‐patient administrative claims database developed by Japan's Ministry of Health, Labour and Welfare that covers more than 126 million people and 1·9 billion claims annually.…”

Current Status of the Obstetric Compensation System for Cases of Cerebral Palsy at a General Hospital in Tochigi, Japan

“…The prevalence of cerebral palsy is reported to be approximately 2 per 1000 live births. 1,2,11,12 Since about 1 million babies were born annually until 2015, the number of children with cerebral palsy was estimated to be approximately 2000 in this country. However, the average number of children certified as being eligible for the JOCSC was 374 between 2009 and 2013, being much lower as compared to the estimated number of children with cerebral palsy.…”
