About the Program

The Alaska Birth Defects Registry (ABDR) was established in 1996 under the Alaska Administrative Code (7 AAC 27.012).

Health care providers, hospitals, and other healthcare facilities are required to report to the ABDR when they have cared for a child with a congenital birth defect.

Public health surveillance systems such as the ABDR provide information on the occurrence and distribution of reportable health conditions within populations.

Registry Objectives

  • Estimate the prevalence of congenital anomalies within Alaska and investigate unusual patterns of occurrence.
  • Monitor the prevalence of birth defects in populations with identifiable or preventable exposures, and determine whether known exposures have increased the risk of birth defects.
  • Conduct analytic studies of high prevalence conditions to elucidate possible etiologies and prevention strategies.
  • Provide scientific foundation for evidence-based decision making.
  • Observe and evaluate the effects of interventions and policy changes.​

Registry Operations

ABDR conducts a modified passive surveillance system. Data collection relies on reporting by major hospitals, specialty clinics and medical record aggregators.

Surveillance is conducted as follows:

  • The reporting facility screens patient records for reportable ICD-10 codes and submits reports to the Registry.
  • Data includes: date of service, child’s name, birthdate, diagnosis information, and reporting agency information.
  • Unique individuals are linked to Vital Statistics data to establish in state birth.
  • Data is maintained for all unique individual and defect combinations reported.
  • Individuals with specific conditions are sampled and medical record reviews are completed to determine reporting error rates for conditions.
  • Individual data and personal identifiers are not released by the registry. Only summarized data are reported.
