Public Health Data for Individual Patient Care: Mapping Poison Control Center Data to the C-CDA Consultation Note

We are developing a new process of health information exchange supported collaboration that leverages the HL7 consolidated CDA standard through four document types (consultation note, history and physical, progress note and discharge summary). The focus of the present study is the C-CDA consultation note template that will be submitted from poison control centers (PCC)s to emergency departments (EDs) with treatment recommendations. Specifically, we aimed to (i) create computable mappings between a poison control center database and the C-CDA consultation note template; and (ii) assess the extent and nature of information types that successfully map to discrete data elements in a poison control center database. The resulting template and mappings can be used to implement standards-based health information exchange between PCCs and EDs in the U.S. This is a part of the first formal effort to leverage health information exchange standards to support PCC-ED collaboration.
