Although sexual violence is a pressing public health and safety issue, it has historically been challenging to monitor population trends with precision. Approximately 31% of incidents of sexual violence are reported to law enforcement and only 5% lead to an arrest1, making the use of law enforcement data challenging. Syndromic surveillance data from emergency departments provides an opportunity to use care-seeking to more accurately surveil sexual violence without introducing additional burdens on either patients or healthcare providers.

Prior to June 2016, there were 45 registered users of syndromic surveillance data in Washington State, with 29 (64.4%) representing 5 of Washington’s 35 local health jurisdictions and 16 (35.6%) at the state level. Of those registered users, 9 (8.8%) had logged into ESSENCE at least once in the 6 months before October 2016. In June 2016, the Washington State syndromic surveillance program began accepting Meaningful Use data and sought to increase its user base.
