Effect of state insurance mandates on racial/ethnic disparities in the utilization and outcomes of donor oocyte-assisted reproductive technologies.

Objective: To characterize racial/ethnic disparities in donor oocyte-assisted reproductive technology (ART) nationwide and examine the impact of state insurance mandates on disparities in utilization and outcomes.

Design: Retrospective cohort study.

Setting: Donor oocyte ART cycles in the United States (US).

Patient(s): Women who underwent donor oocyte ART in 2014-2016, as reported to the Society for Assisted Reproductive Technology Clinic Outcome Reporting System.

Intervention(s): Race/ethnicity of oocyte recipients.

Main Outcome Measure(s): Live birth through 1 or more donor oocyte ART cycles in 2014-2016 per recipient.

Result(s): We analyzed 44,033 donor ART cycles performed for 28,157 oocyte recipients, 99.2% (27,919/28,157) of whom were aged 25-54 years. Race/ethnicity data were reported for 61.4% (17,281/28,157) of the recipients. Among recipients aged 25-54 years with race data, 65.8% (11,264/17,128) identified as non-Hispanic White, whereas 58.9% were White among women aged 25-54 in the 2016 US census. In contrast, Black recipients comprised 8.3% of those aged 25-54 years with race data, compared with 13.7% nationwide. Among White recipients, 7.0% (791/11,356) lived in states with donor ART mandates (Massachusetts/New Jersey), compared with 6.5% (93/1,439) of Black recipients, 8.1% (108/1,335) of Hispanic recipients, and 5.8% (184/3,151) of Asian recipients. Black recipients had a higher median age and body mass index and were more likely to have uterine factor infertility. White recipients had the highest cumulative probability of live birth in the nonmandate (64.6%, 6,820/10,565) and mandate (69.5%, 550/791) states, followed by Asian recipients (nonmandate, 63.4% [1,881/2,967]; mandate, 65.2% [120/184]), Hispanic recipients (nonmandate, 60.5% [742/1,227]; mandate, 68.5% [74/108]), and Black recipients (nonmandate, 48.7% [655/1,346]; mandate, 48.4% [45/93]). The multivariable Poisson regression adjusting for donor's age and recipient's age, body mass index, nulliparity, history of recurrent pregnancy loss, diminished ovarian reserve, tubal factor and uterine factor infertility, prior ART treatment, use of preimplantation genetic testing, cumulative number of embryos transferred, use of blastocysts, and frozen-thawed transfers, demonstrated that Black recipients had a lower cumulative probability of a live birth than White recipients (relative risk [RR], 0.82; 95% confidence interval [CI], 0.77-0.87), as were Hispanic recipients (RR, 0.93; 95% CI, 0.89-0.99) and Asian recipients (RR, 0.96; 95% CI, 0.93-0.99). These disparities were not modified by state mandate for donor ART.

Conclusion(s): State mandates for donor oocyte ART in their current forms are insufficient in decreasing racial/ethnic disparities.
