Standardized rate of hospitalization for violent injuries among different generations in counties and cities in Taiwan from 2000 to 2015.

This study aimed to understand the distribution of the standardized rate of hospitalization for violent injuries in counties and cities in Taiwan. The ICD-9 diagnosis code N-codes 995.5 (abused child) and 995.8 (abused adult) or E-code E960-E969 (homicide and intentional injury by others) were defined as research cases. The study analyzed the standardized medical treatment rate of children and adolescents aged 0 to 17, adults aged 18 to 64, and older adults over 65 years old suffering from violence for the first time. During the 15-year period, the counties and cities with the highest rate of medical treatment for violent injuries among children (unit: per 105 people) were Pingtung County (33.1 males, 22.9 females), Lienchiang County (8.8 males, 9.8 females), and New Taipei City (8.2 males, 8.8 females). For adults, Pingtung County (73.2 males, 36.8 females), New Taipei City (26.0 males, 14.3 females), and Yunlin County (19.7 males, 7.7 females) registered the highest rates. For older adults, Pingtung County (33.6 persons), New Taipei City (12.5 persons), Yun Lin County (11.2 persons), and Taichung City (9.2 persons) registered the highest rates. The highest rates of older female adults receiving treatment were recorded in Pingtung County (15.1 persons), Yunlin County (9.0 persons), Taichung City (5.5 persons), and New Taipei City (5.1 persons). With the Poisson regression model, the relative risk ratio of seeking medical care owing to violence in Pingtung County (reference: Taipei City) was 25.1 times for children, 20.1 times for adults, and 11.7 times for older adults. The counties and cities with higher rates of violent medical treatment for adults and older adults during the 15-year period were Pingtung County, New Taipei City, and Yunlin County. For children and adolescents, Pingtung County, Lienchiang County, and New Taipei City recorded the highest rates. Pingtung County had the highest risk of sexual violence. These results may be related to the local industrial structure, demographic composition, and other characteristics explained in the text.
