Electronic Laboratory Reporting (ELR)

Historically, communicable disease reporting to state and county health departments was paper-based, relying heavily on FAX, telephone and snail mail. Today's sophisticated laboratory information systems bring an opportunity to move toward more timely and efficient electronic laboratory reporting. ELR data are critical to Public Health disease surveillance programs and thus to population health.

The Oregon ELR Project provides a one-stop dropoff point for laboratories to submit reportable data using electronic data interchange. In this system, the Public Health Division functions as an electronic hub to accept, route, and process electronic HL7 messages containing lab and clinical data.

Public Health Meaningful Use

ELR is a required Meaningful Use measure for Eligible Hospitals in Oregon. To meet MU requirements, laboratory data must be sent from an ONC certified EHR (which usually includes Laboratory Information Systems (LIS)). Read more about Oregon Public Health Meaningful Use...
