The Erie County Health Department partnered with HealtheLink in 2011 to access the HealtheLink repository of patient data in order to obtain demographic and treatment information for patients with positive lab results. The New York State Health Department provides reports to local health departments on positive lab results that require public health follow-up. Erie County Health Department uses the HealtheLink master patient index (MPI) to locate cases and clinical information to verify patient treatment. HealtheLink provides primary and alternate contacts along with alternate phone numbers from their MPI. Using the HealtheLink virtual health record, Erie County Health Department can confirm the disease diagnosis, review pending labs and lab results, view radiology results, and evaluate a full clinical picture of a patient’s course of illness. In the first six months of 2015, the Erie County Health Department made 20,000 queries to the HealtheLink virtual patient record.
