The aim of this study is to analyze the health care costs of violence against women. For the study, we used a register-based approach where we identified victims of violence and assessed their actual health care costs at individual level in a bottom-up analysis. Furthermore, we identified a reference population. We computed the attributable costs, that is, the excess health care costs for victims compared to an identified reference population of nonvictims. Only costs within the health care sector were included, that is, somatic and psychiatric hospital costs, costs within the primary health care sector and costs of prescription pharmaceuticals. We estimated the attributable health care costs of violence against women in Denmark, using a generalized linear model where health care costs were modeled as a function of age, childbirth, and exposure to violence. In addition we tested whether socioeconomic status, multiple episodes of violence, and psychiatric contacts had any impact on health care costs. We found that the health care costs were about €1,800 higher for victims of violence than for nonvictims per year, driven mostly by higher psychiatric costs and multiple episodes of violence.
