Trial summary

Investigators will examine trends in ART use in BC specifically. The use of ART has drastically changed the management of infertility, with worldwide estimates exceeding 1.8 million ART cycles in 2010 alone. Moreover, an excess of six million children have been conceived using ART. Read more about this study

About this study

Investigators will examine trends in ART use in BC specifically. The use of ART has drastically changed the management of infertility, with worldwide estimates exceeding 1.8 million ART cycles in 2010 alone. Moreover, an excess of six million children have been conceived using ART. Although various countries have published their live birth rates associated with common ART treatment strategies, British Columbia has yet report on its rates. With varying differences in ART practices, whether clinical or laboratory, it is expected live birth rates due to ART to vary depending on region analyzed. Analyzing the live birth rate in BC would not only allow for a benchmark for assessing future improvement, and trends in infertility diagnosis and management, but also allow for comparison to other provinces and countries. The aim of this part of the study is to describe ART cycle contribution to live birth rate in BC from April 2008 to March 2018, which has not been addressed in the literature as of yet. Not only will it give healthcare providers and patients information about this emerging approach to infertility but also provide a impetus for healthy policy makers to adopt a model for partially or fully publicly funded ART, as seen in Ontario and soon Quebec.

Read the detailed description

Perinatal Services BC maintains a current database on live births, antepartum, intrapartum and postpartum outcomes; including details of ART if used to conceive. Live birth rate, for the purposes of this study, will be defined as the birth of at least one live born baby, with the birth of twins or higher order multiples considered as one live birth. The birth rate for ART will be taken as a proportion for birth rate from ART over total birth rate for given calendar year and the overall period of analysis. Data from April 1 2008 to March 31 2018 on autologous ART treatment cycles and outcomes will be extracted from this database, with approval. Overall proportion of ART contributing to live birth rate will be analyzed as well as sub categorical analysis based on age (younger than 30, 30-34 years, 35-39 years, 40-44 years, and 45 years and older). Only nulliparous women will be included in this study.

Moreover, data will be analyzed by calendar year in which baby from ART delivered to evaluate overall trends in ART outcomes. The total live birth rate for all of BC will serve as the denominator.

Although the data will be reviewed and rules interpreted by the principal investigator of this study, a biostatistician will be hired to carry out the necessary statistical analysis.

Questions about this trial

What is this clinical trial studying?

An observational study of Assisted Reproductive Techniques, run by University of British Columbia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 13 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Live birth rate (time frame: Date of delivery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Dec 2024.
