Inpatient hospitalizations in women with and without assisted reproductive technology live birth

Purpose

The aim of this study is to evaluate frequency of hospitalization before, during, and after assisted reproductive technology (ART) treatment by cycle outcome.

Methods

Six thousand and one hundred thirty women residing in Massachusetts undergoing 17,135 cycles of ART reported to the Society for Assisted Reproductive Technology Clinic Outcome Reporting System (SARTCORS) from 2004 to 2011 were linked to hospital discharges and vital records. Women were grouped according to ART treatment cycle outcome as: no pregnancy (n = 1840), one or more pregnancies but no live birth (n = 968), or one or more singleton live births (n = 3322). Hospital delivery discharges during 1998–2011 were categorized as occurring before, during, or after the ART treatment. The most prevalent ICD-9 codes for non-delivery hospital discharges were compared. Groups were compared using chi square test using SAS 9.3 software.

Results

The proportion of any hospitalization was 57.0, 58.3, and 91.3% for women with no pregnancy, no live birth, and ART singleton live birth, respectively; the proportion of non-delivery hospitalizations was 30.4, 31.0, and 28.3%, respectively. The non-ART delivery proportion after ART treatment did not differ by group (33.4, 36.2, and 36.9%, respectively, p = 0.17). Most frequent non-delivery diagnoses (including fibroids, obesity, ectopic pregnancy, depression, and endometriosis) also did not differ by group. A secondary analysis limited to only women with no delivery discharges before the first ART cycle showed similar results.

Conclusions

All groups had live birth deliveries during the study period, suggesting an important contribution of non-ART treatment or treatment-independent conception to overall delivery and live births. Hospitalizations not associated with delivery suggested similarity in morbidity for all ART patients regardless of success with ART treatment.
