Public health surveillance systems should be evaluated periodically to ensure systems are effectively and efficiently monitoring issues of public health importance. This is particularly difficult regarding the surveillance of intimate partner violence (IPV), which utilizes many disparate sources of data due to the complex nature of IPV and limited available resources. Using CDC’s “Updated Guidelines for Evaluating Public Health Surveillance Systems,” the Minnesota Department of Health (MDH) developed a mixed-methods evaluation of the statewide IPV surveillance system. Qualitative and quantitative methods were used to assess how disparate data sources create an integrated IPV surveillance system in Minnesota. Discussion will focus on how a mixed-methods evaluation was developed, why this methodology was appropriate, and how other states or agencies can apply the lessons learned in Minnesota to improve IPV surveillance systems.Eval19, 2019 Conference
