Does patient accessible electronic health records (PAEHR) result in increased risk of threats and violence? This study was conducted one year after launching PAEHR in Uppsala to examine whether staff whose patients had gained access to the patient portal perceived greater risks of threats and violence, and were exposed to more threats and violence, than those whose patients had not yet gained access. A total of 174 (35%) professionals responded to a web survey. 83 were from the emergency department, whose patients had online electronic health record access, and 91 were from the psychiatric department, whose patients had not. 40% of all participating professionals believed that risks of threats and violence increase after launch. The results did not support a correlation with more incidents of threats and violence, and only one respondent reported that patient access had played any significant negative role in relation to an incident.
