OPC data are available within the ESSENCE application to OHA syndromic surveillance staff. Sending OPC data into ESSENCE allows OHA staff to monitor timely OPC data in an automated, routine manner. When alerts are generated within the ESSENCE system, they are first assessed by syndromic surveillance staff. Those that require follow-up trigger a call between OHA and OPC. Oregon is the first state to use the NPDS web service to upload poison center data into ESSENCE.
