Cost analysis of singleton versus twin pregnancies after in vitro fertilization.

OBJECTIVE: To determine the difference in costs between singleton and twin pregnancies after IVF treatment from pregnancy to 6 weeks after delivery from a health care perspective. DESIGN: Retrospective cost analysis. SETTING: IVF department at the University Medical Center Nijmegen, The Netherlands. PATIENT(S): A representative sample of singleton and twin pregnancies after IVF treatment between 1995 and 2001 at the University Medical Center Nijmegen. INTERVENTION(S): IVF with or without intracytoplasmic sperm injection and with or without cryopreservation. MAIN OUTCOME MEASURE(S): Medical costs per singleton and twin pregnancy after IVF. RESULT(S): In patients pregnant with twins, the incidence of hospital antenatal care, complicated vaginal deliveries, and cesarean sections was higher and was associated with more frequent and longer maternal and neonatal hospital admissions. Maternal and neonatal hospital admissions were the major cost drivers. The medical cost per twin pregnancy was found to be more than five times higher than per singleton pregnancy, 13,469 and 2,550, respectively. CONCLUSION(S): The medical cost per twin pregnancy was more than 10,000 higher than per singleton pregnancy. A reduction in the number of twin pregnancies by elective single ET will save substantial amounts of money. This money might be used for the additional IVF cycles that will probably be needed to achieve similar success rates between single ET and two-embryo transfer
