Abstract

Abstract title
International Committee for Monitoring Assisted Reproductive Technologies (ICMART) Preliminary World Report on ART, 2019

Study question
In 2019 what was the global utilization, effectiveness and safety of ART?

Summary answer
Globally, ART utilization and data collection continue to increase but with wide variations in utilization, effectiveness and safety.

What is known already
ICMART began ART global data collection in 1991. Utilization, effectiveness and safety have continuously improved with more cycles, higher pregnancy rates and lower multiple birth rates, the latter due to the transfer of fewer embryos. Frozen embryo transfer (FET) and donor egg cycles continue to increase. However, wide variations in practice and outcomes exist globally. Approximately 10 million ART babies have been born. ICMART has helped develop registries internationally. A new electronic data collection platform has been developed with the University of New South Wales (UNSW) in Sydney, Australia; nevertheless, data collection and quality remain challenging.

Study design, size, duration
Countries and regions annually collect ART data, some prospectively and others retrospectively. ICMART retrospectively requested data from all known global sources for 2019 and reviewed them for missing or incorrect data. The dataset was reviewed and corrected by ICMART, in partnership with UNSW for validation and analysis, then ICMART finalized the results tables. Standardized definitions from The International Glossary on Infertility and Fertility Care, 2017, and previously developed methods were used. Preliminary results are presented.

Participants/materials, setting, methods
The European IVF Monitoring Consortium (EIM), Latin American Network of Assisted Reproduction (REDLARA), Australian/ New Zealand Registry and African Network and Registry for ART (ANARA) submitted regional data, and other countries contributed national data, through standardized formats, to ICMART. A few individual clinics with no registry access also contributed. Data received were reviewed, corrected, and validated to the extent possible, analyzed and summarized by ICMART using descriptive statistics.

Main results and the role of chance
Data collection and analysis are ongoing, so the presented results are preliminary. The number of ART cycles continues to increase, but utilization is still highly variable among countries and regions. Regional and country differences persist in the age of women treated, number of embryos transferred, live birth rates, rate of multiple births, use of ICSI, cryopreservation cycles and other factors.
The role of chance is minimal. Actual global ART results are limited to reporting countries and clinics representing 90 to 95% of global cycles. However, this is a very large sample size from which imputation of total global results is performed.

Limitations, reasons for caution
Most, but not all, countries report to ICMART. Some countries have limited data and many countries have limited data validation. ICMART can perform only minimal verification of submitted data. Widespread adherence to consensus definitions provided in the Glossary takes time and requires translation into multiple languages. Standardization of validation and reporting is an ongoing process because of missing data and continuing changes in clinical practice.

Wider implications of the findings
ICMART World Reports standardize data, track trends, enable comparisons, stimulate questions and improve ART quality. Better understanding of ART increases societal acceptance and support for equitable access and ART research.
