The study sample was 2007 birth cohort from Taiwan's National Health Insurance (NHI). Cases were defined as children who had ICD-9-CM N-code 995.5x and E-code E960-E969 diagnosis codes from their discharge data. Then we conducted a retrospective nested case-control study to compare patterns of health service utilization between case and control subjects in the year before their first abuse diagnosis. The results demonstrated that the abused diagnosis cumulative incidence rate of 2007 birth cohort was 19 per 10 thousand persons.The most abuse type of first abuse diagnosis was other abuse type, and the most cases were first diagnosed in ED settings. The risk factors of child abuse were female, low-income households, living in low urbanization area. Within one year before the first abused diagnosis, the cases were more likely to have had injury-related ED visits, non-injury-related ED visits, and non-injury-related hospital admissions. Within one year after the first abused diagnosis, the percentage of injury-related health care utilization of children who first received abused diagnosis in the hospital admission settings was high, and the percentage of recurrent child abuseof children who first received abused diagnosis in the outpatient settings was high.
