Why the syndrome was created:
CDC staff were interested in understanding new uses for syndromic surveillance data, particularly in relation to maternal health and health-seeking behavior for pregnant women. Given this, CDC develop a syndrome definition to identify pregnancy, delivery, and pregnancy loss visits. These topics were picked after consideration of the overlapping health-seeking behaviors for pregnancy, delivery, and pregnancy loss, and the difficulty in differentiating between them based on chief complaints and Discharge diagnoses.
Data sources the syndrome was used on (e.g., emergency room, EMS, air quality):
Emergency room
Fields used to query the data (e.g., chief complaint, discharge diagnosis, triage notes):
Chief complaint, discharge diagnosis
