RESUMO

Importance: A publicly funded fertility program was introduced in Ontario, Canada, in 2015 to increase access to fertility treatment. For in vitro fertilization (IVF), the program mandated an elective single-embryo transfer (eSET) policy. However, ovulation induction and intrauterine insemination (OI/IUI)-2 other common forms of fertility treatment-were more difficult to regulate in this manner. Furthermore, prior epidemiologic studies only assessed fetuses at birth and did not account for potential fetal reductions that may have been performed earlier in pregnancy. Objective: To examine the association between fertility treatment and the risk of multifetal pregnancy in a publicly funded fertility program, accounting for both fetal reductions and all live births and stillbirths. Design, Setting, and Participants: This population-based, retrospective cohort study used linked administrative health databases at ICES to examine all births and fetal reductions in Ontario, Canada, from April 1, 2006, to March 31, 2021. Exposure: Mode of conception: (1) unassisted conception, (2) OI/IUI, or (3) IVF. Main Outcomes and Measures: The main outcome was multifetal pregnancy (ie, a twin or higher-order pregnancy). Modified Poisson regression generated adjusted relative risks (ARRs) and derived population attributable fractions (PAFs) for multifetal pregnancies attributable to fertility treatment. Absolute rate differences (ARDs) were used to compare the era before eSET was promoted (2006-2011) with the era after the introduction of the eSET mandate (2016-2021). Results: Of all 1 724 899 pregnancies, 1 670 825 (96.9%) were by unassisted conception (mean [SD] maternal age, 30.6 [5.2] years), 24 395 (1.4%) by OI/IUI (mean [SD] maternal age, 33.1 [4.4] years), and 29 679 (1.7%) by IVF (mean [SD] maternal age, 35.8 [4.7] years). In contrast to unassisted conception, individuals who received OI/IUI or IVF tended to be older, reside in a high-income quintile neighborhood, or have preexisting health conditions. Multifetal pregnancy rates were 1.4% (95% CI, 1.4%-1.4%) for unassisted conception, 10.5% (95% CI, 10.2%-10.9%) after OI/IUI, and 15.5% (95% CI, 15.1%-15.9%) after IVF. Compared with unassisted conception, the ARR of any multifetal pregnancy was 7.0 (95% CI, 6.7-7.3) after OI/IUI and 9.9 (95% CI, 9.6-10.3) after IVF, with corresponding PAFs of 7.1% (95% CI, 7.1%-7.2%) and 13.4% (95% CI, 13.3%-13.4%). Between the eras of 2006 to 2011 and 2016 to 2021, multifetal pregnancy rates decreased from 12.9% to 9.1% with OI/IUI (ARD, -3.8%; 95% CI, -4.2% to -3.4%) and from 29.4% to 7.1% with IVF (ARD, -22.3%; 95% CI, -23.2% to -21.6%). Conclusions and Relevance: In this cohort study of more than 1.7 million pregnancies in Ontario, Canada, a publicly funded IVF program mandating an eSET policy was associated with a reduction in multifetal pregnancy rates. Nevertheless, ongoing strategies are needed to decrease multifetal pregnancy, especially in those undergoing OI/IUI.

RESUMO

PURPOSE: The introduction of the time-lapse monitoring system (TMS) and the development of predictive algorithms could contribute to the optimal embryos selection for transfer. Therefore, the present study aims at investigating the efficiency of KIDScore and iDAScore systems for blastocyst stage embryos in predicting live birth events. METHODS: The present retrospective study was conducted in a private IVF Unit setting throughout a 10-month period from October 2021 to July 2022, and included the analysis of 429 embryos deriving from 91 IVF/ICSI cycles conducted due to infertility of various etiologies. Embryos incubated at the Embryoscope+ timelapse incubator were analyzed through the established scoring systems: KIDScore and iDAScore®. The main outcome measure was the comparison of the two scoring systems in terms of live birth prediction. Embryos with the higher scores at day 5 (KID5 score/iDA5 score) were transferred or cryopreserved for later use. RESULTS: Embryos with high KID5 and iDA5 scores positively correlated with the probability of successful live birth, with KID5 score yielding a higher efficiency in predicting a successful reproductive outcome compared to a proportionally high iDA5 score. KID5 demonstrated conservative performance in successfully predicting live birth compared to iDA5 score, indicating that an efficient prediction can be either provided by a relatively lower KID5 score or a relatively higher iDA5 score. CONCLUSION: The developed artificial intelligence tools should be implemented in clinical practice in conjunction with the conventional morphological assessment for the conduction of optimized embryo transfer in terms of a successful live birth.

RESUMO

AIM: The present study aimed to estimate the total numbers of obstetric diseases diagnosed, total amounts of medical expenses claimed for obstetric diseases, their averages per livebirth, and yearly trends in Japan. METHODS: This is a secondary analysis of the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB) (data from 2015 to 2019). The target population was women of reproductive age (15-49 years old) with diseases in pregnancy, childbirth, and the puerperium, defined by having O codes according to the International Classification of Diseases 10th Revision. We calculated the numbers of obstetric diseases diagnosed, amounts of medical expenses claimed for obstetric diseases marked with the "main injury/disease decision flag," and the totals divided by the annual numbers of livebirths, by year and women's age group. RESULTS: From 2015 to 2019, both the numbers of obstetric diseases diagnosed and amounts of medical expenses claimed for obstetric diseases per livebirth were on an upward trend, whereas the total numbers of obstetric diseases diagnosed were decreased. Women in advanced age groups had a higher number of diagnoses and a higher amount of medical expenses for obstetric diseases per livebirth. "Preterm labour without delivery" had the highest amounts of medical expenses claimed for and the second highest numbers of diagnoses throughout the study period. CONCLUSIONS: This study suggests that pregnant women in Japan would have an increasing number of obstetric complications and necessary medical expenses year by year. Further study is warranted to elucidate these trends and identify possible mitigation measures.

RESUMO

INTRODUCTION: Puerto Rico (PR) has an ambiguous status within Centers for Disease Control and Prevention (CDC) public health monitoring and surveillance systems. However, as a U.S. territory, PR relies on federal health resource allocation processes that are informed by these data sources. This study sought to quantify the coverage of PR within CDC-supported systems compared with the 50 states, describe coverage across critical system-types, and assess the availability of data collection instruments in Spanish. METHODS: This cross-sectional observational study employed the method of data curation by identifying, collecting, and categorizing data primarily from web-based sources maintained by the CDC. Data were originally collected and coded from August 2021 to March 2022 and reviewed by two additional coders from October 2022 to March 2023. Each curated system was assessed to determine coverage of PR across five system-types (probability-based, case-based, administrative, registry, and multiple-source) compared with the 50 states. The availability of data collection instruments in Spanish was also assessed. RESULTS: Of 93 active CDC-supported systems assessed, results revealed that PR was not covered in 54% of CDC-supported systems. Comparatively, inclusive coverage of all 50 states was only lacking in 33% of CDC-supported systems. Of the 32 CDC-supported systems in PR that could be coded for language, only 53% had data collection instruments in Spanish. CONCLUSIONS: There are significant gaps in the coverage of PR within CDC-supported systems. Future efforts must be made to identify the reasons for this exclusion and increase the territory's representation within these essential public health data systems.

RESUMO

BACKGROUND: Medically assisted reproduction (MAR) is a challenging application area for health economic evaluations, entailing a broad range of costs and outcomes, stretching out long-term and accruing to several parties. PURPOSE: To systematically review which costs and outcomes are included in published economic evaluations of MAR and to compare these with health technology assessment (HTA) prescriptions about which cost and outcomes should be considered for different evaluation objectives. DATA SOURCES: HTA guidelines and systematic searches of PubMed Central, Embase, WOS CC, CINAHL, Cochrane (CENTRAL), HTA, and NHS EED. STUDY SELECTION: All economic evaluations of MAR published from 2010 to 2022. DATA EXTRACTION: A predetermined data collection form summarized study characteristics. Essential costs and outcomes of MAR were listed based on HTA and treatment guidelines for different evaluation objectives. For each study, included costs and outcomes were reviewed. DATA SYNTHESIS: The review identified 93 cost-effectiveness estimates, of which 57% were expressed as cost-per-(healthy)-live-birth, 19% as cost-per-pregnancy, and 47% adopted a clinic perspective. Few adopted societal perspectives and only 2% used quality-adjusted life-years (QALYs). Broader evaluations omitted various relevant costs and outcomes related to MAR. There are several cost and outcome categories for which available HTA guidelines do not provide conclusive directions regarding inclusion or exclusion. LIMITATIONS: Studies published before 2010 and of interventions not clearly labeled as MAR were excluded. We focus on methods rather than which MAR treatments are cost-effective. CONCLUSIONS: Economic evaluations of MAR typically calculate a short-term cost-per-live-birth from a clinic perspective. Broader analyses, using cost-per-QALY or BCRs from societal perspectives, considering the full scope of reproduction-related costs and outcomes, are scarce and often incomplete. We provide a summary of costs and outcomes for future research guidance and identify areas requiring HTA methodological development. HIGHLIGHTS: The cost-effectiveness of MAR procedures can be exceptionally complex to estimate as there is a broad range of costs and outcomes involved, in principle stretching out over multiple generations and over many stakeholders.We list 21 key areas of costs and outcomes of MAR. Which of these needs to be accounted for alters for different evaluation objectives (determined by the type of economic evaluation, time horizon considered, and perspective).Published studies mostly investigate cost-effectiveness in the very short-term, from a clinic perspective, expressed as cost-per-live-birth. There is a lack of comprehensive economic evaluations that adopt a broader perspective with a longer time horizon. The broader the evaluation objective, the more relevant costs and outcomes were excluded.For several costs and outcomes, particularly those relevant for broader, societal evaluations of MAR, the inclusion or exclusion is theoretically ambiguous, and HTA guidelines do not offer sufficient guidance.

RESUMO

Importance: While various policies to support couples experiencing infertility have been introduced due to the fertility rate rapidly dropping in developed countries, few large-scale nationwide cohort studies have evaluated the outcomes of assisted reproductive technology (ART) health insurance coverage policies. Objective: To evaluate ART health insurance coverage for multiple pregnancies and births in Korea. Design, Setting, and Participants: This population-based cohort study used delivery cohort data from the Korean National Health Insurance Service database between July 1, 2015, and December 31, 2019. A total of 1 474 484 women were included after exclusion of those who gave birth at nonmedical institutions and those with missing data. Exposure: Two 27-month periods were examined before and after the Korean National Health Insurance Service had begun covering ART treatment (preintervention period, July 1, 2015, to September 30, 2017; postintervention period, October 1, 2017, to December 31, 2019). Main Outcomes and Measures: Multiple pregnancies and multiple births were identified by International Statistical Classification of Diseases and Related Health Problems, Tenth Revision diagnosis codes. Total births were defined as the total number of babies born to each pregnant woman during the follow-up period. An interrupted time series with segmented regression was conducted to analyze the time trend and its change in outcomes. Data analysis was conducted between December 2, 2022, and February 15, 2023. Results: Of the 1 474 484 women eligible for the analysis (mean [SD] age, 33.2 [4.6] years), approximately 1.60% had multiple pregnancies and 1.10% had multiple births. After covering ART treatment, the likelihood of multiple pregnancies and multiple births was estimated to increase by 0.7% (estimate, 1.007; 95% CI, 1.004-1.011; P < .001) and 1.2% (estimate, 1.012; 95% CI, 1.007-1.016; P < .001) compared with before coverage. The probability of an increase in the number of total births per pregnant woman after the intervention was estimated to be 0.5% (estimate, 1.005; 95% CI, 1.005-1.005; P < .001). The relatively high-income class above the median income showed a decreasing trend in multiple births and total births before the intervention, but after the intervention, a significant increase was observed. Conclusions and Relevance: This population-based cohort study found that the possibility of multiple pregnancies and births in Korea significantly increased after the implementation of an ART health insurance coverage policy. These findings suggest that the development and coverage of policies to support couples experiencing infertility may help address low fertility rates.

RESUMO

Considerable costs are associated with infertility treatment, but little evidence is available on the main drivers of treatment costs. This cost analysis investigated key costs for treatment with assisted reproductive technology (ART) and the proportion of costs attributed to the acquisition of recombinant human follicle-stimulating hormone (r-hFSH) alfa originator for one fresh embryo transfer (ET) leading to a live birth in Spain, Norway, the UK, Germany, Denmark, South Korea, Australia, and New Zealand. The total costs for one ART cycle with a fresh ET leading to a live birth varied between countries (€4108-€12,314). Costs for pregnancy and live birth were the major contributors in European countries, and the costs of oocyte retrieval, monitoring during ovarian stimulation, pregnancy, and live birth were the top contributors in the Asia-Pacific countries, included in this analysis. Acquisition costs for r-hFSH alfa originator contributed to only 5%-17% of the total costs of one ART cycle with one fresh ET leading to a live birth.

RESUMO

OBJECTIVE: to analyze the trend of incompleteness of the maternal schooling and race/skin color variables held on the Brazilian Live Birth Information System (SINASC) between 2012 and 2020. METHODS: this was an ecological time series study of the incompleteness of maternal schooling and race/skin color data for Brazil, its regions and Federative Units, by means of joinpoint regression and calculation of annual percentage change (APC) and average annual percentage change. RESULTS: a total of 26,112,301 births were registered in Brazil in the period; incompleteness of maternal schooling data decreased for Brazil (APC = -8.1%) and the Southeast (APC = -19.5%) and Midwest (APC = -17.6%) regions; as for race/skin color, there was a downward trend for Brazil (APC = -8.2%) and all regions, except the Northeast region, while nine Federative Units and the Federal District showed a stationary trend. CONCLUSION: there was an improvement in filling out these variables on the SINASC, but with regional disparities, mainly for race/skin color.

RESUMO

INTRODUCTION: Despite progress in recent years, full antenatal care utilization in India continues to be relatively low and inequitable, particularly between states and districts. In 2015-2016, for example, only 51% of women aged 15-49 in India attended antenatal care at least four times during pregnancy. Using data from the fifth iteration of India's National Family Health Survey, our study aims to explore factors related to the underutilization of antenatal care in India. MATERIALS AND METHODS: Data from the most recent live birth in the past five years among women aged 15-49 years were included in our analysis (n = 172,702). Our outcome variable was "adequate antenatal care visits", defined as four or more antenatal visits. Utilizing Andersen's behavioral model, 14 factors were identified as possible explanatory variables. We used univariate and multivariate binary logistic regression models to analyze the association between explanatory variables and adequate visits. Associations were considered statistically significant if p<0.05. RESULTS: Of the 172,702 women in our sample, 40.75% (95% CI: 40.31-41.18%) had an inadequate number of antenatal care visits. In multivariate analysis, women with less formal education, from poorer households and more rural areas had higher odds of inadequate visits. Regionally, women from Northeastern and Central states had higher odds of inadequate antenatal care utilization compared to those from Southern states. Caste, birth order, and pregnancy intention were also among the variables associated with utilization of antenatal care. DISCUSSION: Despite improvements in antenatal care utilization, there is cause for concern. Notably, the percentage of Indian women receiving adequate antenatal care visits is still below the global average. Our analysis also reveals a continuity in the groups of women at highest risk for inadequate visits, which may be due to structural drivers of inequality in healthcare access. To improve maternal health and access to antenatal care services, interventions aimed at poverty alleviation, infrastructure development, and education should be pursued.

RESUMO

Access to health care coverage during pregnancy and delivery allows women to receive the care needed to maximize the likelihood of a healthy pregnancy and baby (1). National birth certificate data on the principal source of payment for the delivery became available in 2016, when all states implemented the 2003 U.S. Standard Certificate of Live Birth. This certificate provides information on payment through private insurance; Medicaid; CHAMPUS, TRICARE, and other types of government insurance; and self-pay, which has been shown to reflect the uninsured status of the mother at the time of delivery (2). This report describes the principal source of payment for the delivery in 2021 overall and by maternal race and Hispanic origin, age, and education.

RESUMO

INTRODUCTION: The World Health Organization recommended a set of five neonatal care practices that are most essential for good health of a newborn. As good essential newborn care (ENC) practice reduces the risk of neonatal morbidity and mortality, this paper focuses how women's multidimensional empowerment index is associated with this practice through the skilled antenatal care. To the best of knowledge, no such study has been conducted yet. The composite index of women's multidimensional empowerments was constructed using family decision, intimate partner violence, social status, healthcare access and economic status of women; and skilled antenatal care was defined if a pregnant woman received eight or more checkups during pregnancy from skilled health professionals. MATERIALS AND METHODS: Data extracted from Bangladesh Demographic and Health Survey, 2017-18 have been utilized in the study. A total of 2441 mothers have been considered who delivered their last live birth at home within three years preceding the survey. A mediation analysis was performed considering the structural equation modeling to find out the adjusted association of women's empowerment on both skilled antenatal care and good ENC practice, but the unadjusted associations were also checked using a chi-square test. To test the indirect as well as total effect of women's empowerment through skilled antenatal care on good ENC practice, bias-corrected standard errors were estimated using a bootstrapping sampling. RESULTS: Good ENC practice was considerably low in Bangladesh with 7.6% of newborns receiving the practice. Both adjusted and unadjusted analyses showed the significant association of women's empowerment with both skilled antenatal care and good ENC practice. The study revealed that the indirect effect of high empowerment through skilled antenatal care was greater than its direct effect on good ENC practice. CONCLUSION: This study explored that the prevalence of good ENC practice can be accelerated through women's empowerment, where skilled antenatal care plays an important mediating role in improving good ENC practice among highly empowered mothers. The study suggests that a woman should follow the latest guidelines recommended by WHO for antenatal care follow-up. Policymakers can modify some of the maternal and child health care interventions based on the research findings.

RESUMO

PURPOSE: The high cost of in vitro fertilization (IVF) procedures coupled with public availability of success rates may influence IVF practice patterns and success rates but may be mitigated by mandated insurance coverage for IVF procedures. This study examined associations of competition with IVF practice patterns and success rates by insurance mandate status. METHODS: We used publicly available 2018 National Assisted Reproductive Technology Surveillance System data from the CDC. We defined competition as distance to nearest clinic and number of clinics within certain radii. We used linear regression to explore associations of competition, insurance mandate status, and interactions between competition and mandate status with clinical practice patterns (e.g., percentage of cycles among patients < 35 years, percentage of cycles using ICSI, average number of embryos transferred) and IVF success rates (e.g., live birth rates). We also assessed the percentage of variation in outcomes explained by our models, R2. RESULTS: For practice patterns, the largest R2 value was 0.3518, meaning only 35.18% of the variability in the practice pattern variable was explained by competition and insurance mandate status. In most cases, the R2 values were less than 0.20, indicating little to no association. Less than 10% of the variability in success rates was explained by competition and insurance mandate status. CONCLUSION: The multiple regression analyses all yielded low R2 values, indicating weak associations. These encouraging results coincide with previous studies, suggesting that competition, even by insurance mandate status, does not have a strong association with IVF practice patterns or success rates.

RESUMO

Preeclampsia is defined as hypertension arising after 20 weeks of gestational age with proteinuria or other signs of end-organ damage and is an important cause of maternal and perinatal morbidity and mortality, particularly when of early onset. Although a significant amount of research has been dedicated in identifying preventive measures for preeclampsia, the incidence of the condition has been relatively unchanged in the last decades. This could be attributed to the fact that the underlying pathophysiology of preeclampsia is not entirely understood. There is increasing evidence suggesting that suboptimal trophoblastic invasion leads to an imbalance of angiogenic and antiangiogenic proteins, ultimately causing widespread inflammation and endothelial damage, increased platelet aggregation, and thrombotic events with placental infarcts. Aspirin at doses below 300 mg selectively and irreversibly inactivates the cyclooxygenase-1 enzyme, suppressing the production of prostaglandins and thromboxane and inhibiting inflammation and platelet aggregation. Such an effect has led to the hypothesis that aspirin could be useful for preventing preeclampsia. The first possible link between the use of aspirin and the prevention of preeclampsia was suggested by a case report published in 1978, followed by the first randomized controlled trial published in 1985. Since then, numerous randomized trials have been published, reporting the safety of the use of aspirin in pregnancy and the inconsistent effects of aspirin on the rates of preeclampsia. These inconsistencies, however, can be largely explained by a high degree of heterogeneity regarding the selection of trial participants, baseline risk of the included women, dosage of aspirin, gestational age of prophylaxis initiation, and preeclampsia definition. An individual patient data meta-analysis has indicated a modest 10% reduction in preeclampsia rates with the use of aspirin, but later meta-analyses of aggregate data have revealed a dose-response effect of aspirin on preeclampsia rates, which is maximized when the medication is initiated before 16 weeks of gestational age. Recently, the Aspirin for Evidence-Based Preeclampsia Prevention trial has revealed that aspirin at a daily dosage of 150 mg, initiated before 16 weeks of gestational age, and given at night to a high-risk population, identified by a combined first trimester screening test, reduces the incidence of preterm preeclampsia by 62%. A secondary analysis of the Aspirin for Evidence-Based Preeclampsia Prevention trial data also indicated a reduction in the length of stay in the neonatal intensive care unit by 68% compared with placebo, mainly because of a reduction in births before 32 weeks of gestational age with preeclampsia. The beneficial effect of aspirin has been found to be similar in subgroups according to different maternal characteristics, except for the presence of chronic hypertension, where no beneficial effect is evident. In addition, the effect size of aspirin has been found to be more pronounced in women with good compliance to treatment. In general, randomized trials are underpowered to investigate the treatment effect of aspirin on the rates of other placental-associated adverse outcomes such as fetal growth restriction and stillbirth. This article summarizes the evidence around aspirin for the prevention of preeclampsia and its complications.

RESUMO

The aim of this retrospective cohort study is to establish whether strategies favoring frozen-thawed embryo transfer (FET) have an impact on differences in cumulative live birth rate (CLBR), weighted mean cost per live birth, and multiple pregnancy rate (MPR) between fertility clinics. Data were extracted from the Assisted Reproductive Technology (ART) Italian National Registry and refer to classical IVF or intracytoplasmic sperm injection (ICSI) cycles performed in 2018 in public funded Lombardy region fertility clinics. Propensity to FET cycles was expressed with the so-called freezing tendency index (FTI): [(No. of FETs + No. of transfers of embryos obtained from frozen-thawed oocytes) / (No. of fresh ETs + No. of canceled IVF cycles + Numerator)] × 100. Fertility clinics were divided according to their FTI: group A (FTI: 0-20%); group B (FTI: 20-40%); and group C (FTI: 40-60%). Groups A, B, and C included 6, 8, and 8 fertility clinics, respectively. The CLBR (95% CI) per started COH cycle was 13.1% (11.8-14.5%) in group A, 19.6% (18.6-20.7%) in group B, and 27.8% (26.8-28.9%) in group C (p < 0.0001). The weighted mean live birth cost was 32,770 ± 10,662 € in group A, 25,863 ± 11,510 € in group B, and 20,426 ± 3788 € in group C (p < 0.0001). The MPR (95% CI) was 15.4% (12.1-19.4%) in group A, 10.2% (8.7-12.1%) in group B (p = 0.0065), and 6.3% (5.2-7.6%) in group C (p = 0.0001). In conclusion, our results suggest that strategies favoring FET cycles are associated with an increased CLBR, a decreased weighted mean cost per live birth, and a decreased MPR.

RESUMO

OBJECTIVE: To quantify the proportion of annual assisted reproductive technology (ART) cycles performed at private equity-affiliated fertility practices and to test for differences in services and success rates between private equity-affiliated and nonaffiliated practices. DESIGN: Cross-sectional analysis of national data set. SETTING: Not applicable. PATIENT(S): None. INTERVENTION(S): Not applicable. MAIN OUTCOME MEASURE(S): The primary outcome measures were the volume of ART cycles performed, the percentage of retrievals resulting in live births, and the percentage of transfers resulting in live births. The secondary outcomes included the median income of the practice location, the use of preimplantation genetic testing, the clinical service availability, and the patient reasons for seeking treatment. RESULT(S): Of the practices listed on the Centers for Disease Control's 2018 Fertility Clinic Success Rates Report, 14.7% had a private equity affiliation. Of the 305,883 ART cycles performed in 2018, 29.3% (89,535) occurred at private equity-affiliated practices. Patients at private equity-affiliated practices were 6.75% (95% confidence interval [CI], -10.15%, -3.36%) less likely to initiate a cycle due to male factor infertility, and 10.60% (95% CI, 3.49, 17.76) more likely to use preimplantation genetic testing before embryo transfer. No statistically significant differences were found in success rates among women aged <35 years. The average median household income (standard error) in zip codes with private equity-affiliated practices compared with nonaffiliated practices was $83,610 ($35,990) and $72,161 ($32,314), respectively. CONCLUSION(S): A major portion of fertility practices in the United States are private equity-affiliated, and these practices perform an even greater portion of ART cycles in the United States each year. Fertility appears to be the medical specialty with the greatest market share owned by private equity. Our findings corroborate preliminary research, which forecasts the increasing involvement and consolidation by private equity in fertility. Future research should continue monitoring for differences in outcomes, financing, case mix, service use, and accessibility.

RESUMO

AIM: Due to the lack of national perinatal registries, population-wide descriptive statistics on cesarean deliveries in Japan are unknown. We aim to describe cesarean deliveries for overall and multiple pregnancies using the Japan National Database of health insurance claims. METHODS: We calculated the national and prefectural cesarean delivery rates for overall and multiple pregnancies in 2014. We described maternal morbidities (e.g., blood transfusion) and the place and type of the institutions providing prenatal and perinatal care. RESULTS: The national cesarean delivery rates were 18.6% overall and 82.7% for women with multiple pregnancies. Prefectural cesarean delivery rates for overall and multiple pregnancies varied from 12.5% to 24.2% and from 49.2% to 100%, respectively, showing a moderate positive correlation (r = 0.59, p < 0.001). Overall, 1.4% of cesarean patients received an allogeneic blood transfusion, compared to 3.2% for those with multiple pregnancies. In addition, 65.9% of overall cesarean deliveries occurred at hospitals with ≥20 beds, whereas 94.6% of cesarean patients with multiple pregnancies delivered at hospitals. Older patients were more likely to receive their cesarean section at a different institution than their first visit within the same prefecture, but trans-prefectural movement during pregnancy covered by health insurance was most frequent among those in their early thirties: 7.0% overall and 10.7% for multiple pregnancies. CONCLUSIONS: The overall cesarean delivery rate in Japan was optimal, but the rate was high for multiple pregnancies, with large regional differences. Data on patient movement across institutions and areas would help to improve the perinatal care system.

RESUMO

Advanced maternal age (AMA) is a growing trend world-wide and is traditionally defined as childbearing in women over 35 years of age. The purpose of our study was to determine the maternal age group within the Korean population, in which the risk of early neonatal mortality is increased. Korean birth and mortality data from 2011 to 2015 were used to estimate the influence of maternal age on the risk of early neonatal mortality. A Poisson regression was used for the analysis of multiple clinical variables such as year of delivery, maternal age, gestational age, infant gender, birth weight, multiple birth, parity, and socioeconomic variables. Furthermore, a generalized additive model was used to determine the maternal age at which the risk for neonatal mortality increases. We included 2,161,908 participants and found that 49.4% of mothers were 30-34 years of age at delivery. The proportion of mothers aged 35 and above increased over the 5-year analysis period. A maternal age lower than 29 years or higher than 40 years was associated with a relatively higher risk of early neonatal mortality. The trend and magnitude of the age-related risk on early neonatal mortality were independent of maternal socioeconomic factors such as living in an obstetrically underserved area, education level, and employment status. Furthermore, we showed that the risk for early neonatal mortality was higher until the maternal age of 28. However, there were no significant changes in the risk between the age of 35 and 40 years. According to recent national-wide data, age-related risk for early neonatal mortality is only apparent for mothers ≥ 40 years old whereas, age between 35 and 39 are not at increased risk for early neonatal mortality, despite being classified as AMA.

RESUMO

The health of children born through assisted reproductive technologies (ART) is particularly vulnerable to policy decisions and market forces that play out before they are even conceived. ART treatment is costly, and public and third-party funding varies significantly between and within countries, leading to considerable variation in consumer affordability globally. These relative cost differences affect not only who can afford to access ART treatment, but also how ART is practiced in terms of embryo transfer practices, with less affordable treatment creating a financial incentive to transfer more than one embryo to maximize the pregnancy rates in fewer cycles. One mechanism for reducing the burden of excessive multiple pregnancies is to link insurance coverage to the number of embryos that can be transferred; another is to combine supportive funding with patient and clinician education and public reporting that emphasizes a "complete" ART cycle (all embryo transfers associated with an egg retrieval) and penalizes multiple embryo transfers. Improving funding for fertility services in a way that respects clinician and patient autonomy and allows patients to undertake a sufficient number of cycles to minimize moral hazard improves outcomes for mothers and babies while reducing the long-term economic burden associated with fertility treatments.
