Clinical Document Architecture (CDA) Standards for Public Health - Early Hearing Detection and Intervention (EHDI)

Communicable Diseases | EHDI

The goals of this project were to enable standardization of Early Hearing Detection and Intervention (EHDI)-related information exchanges by focusing on:

  • developing and testing interoperability standards for Health Information Technology (HIT) products used in EHDI information exchanges, and
  • deploying standards-based HIT solutions in State EHDI Programs

The project included two components:

HIT Standards for Early Hearing Detection and Intervention (EHDI)

PHDSC actively worked on developing two Integrating the Healthcare Enterprise (IHE). EHDI profiles: Early Hearing Detection and Intervention-Workflow Document (EHDI-WD) and to remodel the Early Hearing Care Plan (EHCP).

The Early Hearing Detection and Intervention-Workflow Document (EHDI-WD) Profile will enable execution of a standard workflow to collected data produced during the clinical care process and orchestrate the exchange of data between clinical and program-specific public health information systems.

The Early Hearing Care Plan (EHCP) defines a CDA content document to communicate care plan instructions to manage the detection and intervention of hearing loss in newborns and young children. It includes clinical content such as hearing screening results, the presence of risk indicators for hearing loss, suggested referrals for additional hearing health care, interventions, and instructions for management of the patient's care. The content defined for the ECHP document is pertinent for early hearing detection and intervention (EHDI) and Newborn Hearing Screening programs that exist in the United States and other countries such as England, Scotland and Australia.

EHDI CDA State Pilot Project

PHDSC, in partnership with the CDC Early Hearing Detection and Intervention (EHDI) Data Committee and with the support from CDC, collaborated with the North Dakota and Oregon EHDI Programs and 10 observer states in the design and implementation of two pilot projects to demonstrate electronic data exchange between clinical Electronic Health Record (EHR) Systems and public health EHDI information systems using the Health Level Seven (HL7) Clinical Document Architecture (CDA) standard.
