National assisted reproductive technology (ART) cycle linkage

Abstract

OBJECTIVE: To determine the feasibility of linking all ART cycles in the Society for Assisted Reproductive Technology Clinic Outome Reporting System (SART CORS) for 2004-08 and calculating per cycle and cumulative live birth rates.DESIGN: Historical cohort study.MATERIALS AND METHODS: Cycles reported to the SART CORS between January 1, 2004 and December 31, 2008 were included. Cycles were linked by woman's date of birth, last name, first name, and social security number (when present); linkages across clinics also included partner's name and sequence of ART outcomes, as needed. The following cycles were excluded from the final match: cancelled, research, no outcomes, gestational carriers, and embryo banking and no outcome reported. Cycles were limited to those up to and including the first live birth.Tabled 1Cycles of ARTLive Birth Deliveries in Each Cycle (N)Number of Women at Risk in Each Cycle (N)Live Birth Delivery Rate at Each Cycle (%)Cumulative Live Birth Deliveries (N)Cumulative Live Birth Delivery Rate Per Woman (%)1110,019306,56535.9110,01935.9236,518122,66929.8146,53747.8314,81050,86329.1161,34752.645,80021,29327.2167,14754.552,3559,14525.8169,50255.361,1004,14226.6170,60255.6≥77253,81919.0171,32755.9 Open table in a new tab CONCLUSION: This analysis demonstrates the feasibility of a national linkage of ART cycles, and the calculation of live birth rates per woman.
