Multiple imputation of missing race/ethnicity information in the National Assisted Reproductive Technology Surveillance System
Zhang Y , Kissin DM , Liao KJ , DeSantis CE , Yartel AK , Gutman R . J Womens Health (Larchmt) 2023 Background: Missing race/ethnicity data are common in many surveillance systems and registries, which may limit complete and accurate assessments of racial and ethnic disparities. Centers for Disease Control and Prevention's National Assisted Reproductive Technology (ART) Surveillance System (NASS) has a congressional mandate to collect data on all ART cycles performed by fertility clinics in the United States and provides valuable information on ART utilization and treatment outcomes. However, race/ethnicity data are missing for many ART cycles in NASS. Materials and Methods: We multiply imputed missing race/ethnicity data using variables from NASS and additional zip code-level race/ethnicity information in U.S. Census data. To evaluate imputed data quality, we generated training data by imposing missing values on known race/ethnicity under missing at random assumption, imputed, and examined the relationship between race/ethnicity and the rate of stillbirth per pregnancy. Results: The distribution of imputed race/ethnicity was comparable to the reported one with the largest difference of 0.53% for non-Hispanic Asian. Our imputation procedure was well calibrated and correctly identified that 89.91% (standard error = 0.18) of known race/ethnicity values on average in training data. Compared to complete-case analysis, using multiply imputed data reduced bias of parameter estimates (the range of bias for stillbirth per pregnancy across race/ethnicity groups is 0.02%-0.18% for imputed data analysis, versus 0.04%-0.66% for complete-case analysis) and yielded narrower confidence intervals. Conclusions: Our results underscore the importance of collecting complete race/ethnicity information for ART surveillance. However, when the missingness exists, multiply imputed race/ethnicity can improve the accuracy and precision of health outcomes estimated across racial/ethnic groups. |
State insurance mandates and racial and ethnic inequities in assisted reproductive technology utilization
Korkidakis A , DeSantis CE , Kissin DM , Hacker MR , Koniares K , Yartel A , Adashi EY , Penzias AS . Fertil Steril 2023 121 (1) 54-62 OBJECTIVE: To examine whether the (1) scope of state-mandated insurance coverage for assisted reproductive technology (ART), and (2) proportion of the population eligible for this coverage, are associated with reductions in racial/ethnic inequities in ART utilization. DESIGN: National cross-sectional, ecologic study. SUBJECTS: We employed estimates from the U.S. Census Bureau of all women 20-44 years of age living in the U.S. in 2018. The number of women who initiated an ART cycle during that year that was reported to the U.S. Centers for Disease Control and Prevention (CDC) was obtained from the National ART Surveillance System (NASS). EXPOSURE: State mandates were classified by scope of required coverage for fertility services: Comprehensive, Limited, and No Mandate. MAIN OUTCOMES MEASURES: Race and ethnic-specific ART utilization rates, defined as number of women undergoing ≥1 ART cycles per 10,000 women, were the primary outcome. As state mandates do not apply to all insurance plans, Comprehensive Mandate utilization rates were recalculated using denominators corrected for the estimated proportions of populations eligible for coverage. RESULTS: Across all mandate categories, Non-Hispanic (NH) Asian and NH White populations had the highest ART utilization rates, whereas the lowest rates were among Hispanic, NH Black, and NH Other/Multiple Races populations. As compared to the NH Asian reference group, the NH Black population had smaller inequities in the Comprehensive Mandate group than the No Mandate group (Rate Ratio [RR 0.33 [0.28-0.38] versus RR 0.23 [0.22-0.24]). Using the Comprehensive Mandate group for each race/ethnicity as reference, the NH Black and NH Other/Multiple Races populations had the largest relative differences in utilization between the No Mandate and Comprehensive Mandate groups (RR 0.39 [0.37-0.41] and 0.33 [0.28-0.38], respectively). Within the Comprehensive Mandate group, the disparities in the Hispanic and NH Black populations moved towards the null after correcting for state-mandated insurance eligibility. CONCLUSIONS: Racial/ethnic inequities in ART utilization were reduced in states with comprehensive infertility coverage mandates. Inequities were further attenuated after correcting for mandate eligibility. Mandates alone, however, were not sufficient to eliminate disparities. These findings can inform future strategies aimed at improving ART access under a social justice framework. |
Embryo donation: national trends and outcomes, 2004-2019
Lee JC , DeSantis CE , Boulet SL , Kawwass JF . Am J Obstet Gynecol 2022 228 (3) 318 e1-318 e7 BACKGROUND: In 2016, the US Food and Drug Administration amended existing regulations to increase access to donated embryos for reproductive use. Current information regarding the characteristics and outcomes of embryo donation cycles could benefit patients and providers during counseling and decision making. OBJECTIVE: This study aimed to examine the trends in the utilization of embryo donation, pregnancy rates, and live birth rates per transfer between 2004 and 2019 and to describe the recipients of donated embryos and outcomes of frozen donated embryo transfer cycles during the most recent time period, that is, 2016 to 2019. STUDY DESIGN: We conducted a retrospective, population-based cohort study of frozen donated embryo transfer cycles in United States fertility clinics reporting to the National Assisted Reproductive Technology Surveillance System during 2004 to 2019. The trends in the annual number and proportion of frozen donated embryo transfers, pregnancy rates, and live birth rates from 2004 to 2019 were described. During 2016 to 2019, the rates of cycle cancellation, pregnancy, miscarriage, live birth, singleton birth, and good perinatal outcome (delivery ≥37 weeks, birthweight ≥2500 g) of frozen donated embryo transfers were also calculated. Transfer and pregnancy outcomes stratified by oocyte source age at the time of oocyte retrieval were also described. RESULTS: From 2004 to 2019, there were 21,060 frozen donated embryo transfers in the United States, resulting in 8457 live births. During this period, the annual number and proportion of frozen donated embryo transfers with respect to all transfers increased, as did the pregnancy rate and live birth rate. Among all initiated cycles during 2016 to 2019, the cancellation rate was 8.2%. Among 8773 transfers with known outcomes, 4685 (53.4%) resulted in pregnancy and 3820 (43.5%) in live birth. Among all pregnancies, 814 (17.4%) resulted in miscarriage. Among all live births, 3223 (84.4%) delivered a singleton, of which 2474 (76.8%) had a good perinatal outcome. The clinical pregnancy rate and live birth rate per frozen donated embryo transfer decreased with increasing age of oocyte source. CONCLUSION: The outcomes of embryo donation cycles reported in this national cohort may aid patients and providers when considering the use of donated embryos. |
Factors associated with large-for-gestational-age infants born after frozen embryo transfer cycles
Roshong AJ , DeSantis CE , Yartel AK , Heitmann RJ , Kissin DM , Pier BD . F S Rep 2022 3 (4) 332-341 Objective: To examine trends of frozen embryo transfer (FET) proportions and large-for-gestational-age (LGA) incidence and determine risk factors for LGA infants after FET. Design: Retrospective cohort study. Setting: Not applicable. Patient(s): Frozen embryo transfer cycles. Intervention(s): None. Main Outcome Measure(s): Singleton LGA infant. Result(s): The percentage of FETs increased from 20%–74% of transfers, whereas the rate of LGA among FET singleton births decreased from 18%–12% during 2004–2018. In a subanalysis of 127,525 FET-associated singleton live births during 2016–2018, patient factors associated with LGA were higher-than-normal maternal body mass index (body mass index [BMI], 25.0–29.9 kg/m2; adjusted relative risk [aRR], 1.31; 95% confidence interval [CI], 1.26–1.36; BMI, 30.0–34.9 kg/m2; aRR, 1.48; 95% CI, 1.41–1.55; and BMI, >35 Kg/m2; aRR, 1.68; 95% CI, 1.59–1.77) and ≥1 prior birth vs. none. Low maternal BMI (<18.5 vs. 18.5–24.9 kg/m2) and cycles involving patients who were non-Hispanic (NH) Asian/Native Hawaiian/Pacific Islander, NH Black, or Hispanic (compared with NH White) were at lower risk of LGA infants. Cycle factors associated with LGA included gestational carrier use (aRR, 1.25; 95% CI, 1.16–1.34) and donor sperm (aRR, 1.17; 95% CI, 1.10–1.25). Conclusion(s): Although the number and proportion of FET cycles increased from 2004–2018, the rate of LGA after FET decreased. Maternal BMI, parity, and race/ethnicity were the strongest risk factors for LGA infants after FET. © 2022 |
The association of state insurance coverage mandates with Assisted Reproductive Technology Care discontinuation
Lee JC , DeSantis CE , Yartel AK , Kissin DM , Kawwass JF . Am J Obstet Gynecol 2022 228 (3) 315 e1-315 e14 BACKGROUND: Insurance coverage for fertility services may reduce the financial burden of high-cost fertility care such as assisted reproductive technology and improve its utilization. Patients who exit care after failing to reach their reproductive goals report higher rates of mental health problems and a lower sense of well-being. It is important to understand the relationship between state-mandated insurance coverage for fertility services and assisted reproductive technology care discontinuation. OBJECTIVE: This study aimed to assess whether state-mandated insurance coverage for fertility services is associated with lower rates of care discontinuation after an initial assisted reproductive technology cycle that did not result in a live birth. STUDY DESIGN: This is a retrospective, population-based cohort study using data from United States fertility clinics reporting to the National Assisted Reproductive Technology Surveillance System during 2016 and 2018. Patients who began their first autologous assisted reproductive technology cycle during 2016 and 2017 and did not have a live birth were included. We describe the rate of assisted reproductive technology care discontinuation (no additional cycle within 12 months of the previous cycle's date of failure). Multivariable analyses were conducted to evaluate factors independently associated with care discontinuation, including the scope of fertility services included in state coverage mandate at assisted reproductive technology cycle initiation that were as follows: comprehensive (>/=3 assisted reproductive technology cycles), limited (1, 2, or an unspecified number of assisted reproductive technology cycles), mandate not including assisted reproductive technology, and no mandate. RESULTS: Among 91,324 patients who underwent their first autologous assisted reproductive technology cycle that did not result in live birth, 24,072 (26.4%) discontinued care. Compared with patients who lived in states with mandates for comprehensive assisted reproductive technology coverage, those in states with mandates for fertility services coverage that did not include assisted reproductive technology or states with no mandate were 46% (adjusted relative risk, 1.46; 95% confidence interval, 1.31-1.63) and 26% (adjusted relative risk, 1.26; 95% confidence interval, 1.15-1.39) more likely to discontinue care, respectively, after controlling for patient and cycle characteristics. Increasing patient age, distance from clinic >/=50 miles, previous live birth, fewer oocytes retrieved, and not having embryos cryopreserved were also associated with higher rates of discontinuation. Non-Hispanic Black, non-Hispanic Asian, and Hispanic patients had higher rates of care discontinuation than non-Hispanic White patients regardless of the existence or scope of state-mandated assisted reproductive technology coverage. CONCLUSION: Comprehensive state-mandated insurance coverage for assisted reproductive technology is associated with lower rates of assisted reproductive technology care discontinuation. |
