A consensus-based core data set was developed to assess long-acting and permanent contraceptive performance. This Women's Health Technology Coordinated Registry Network (WHT-CRN) initiative will improve contraceptive safety and effectiveness evaluations.
Area of Science:
- Reproductive Health
- Medical Device Technology
- Health Informatics
Background:
- A multistakeholder expert group was convened under the Women's Health Technology Coordinated Registry Network (WHT-CRN).
- The group aimed to establish a national infrastructure for capturing the performance of long-acting and permanent contraceptives.
- Key objectives included defining the role and feasibility of the CRN and identifying essential data elements for assessing contraceptive technologies.
Purpose of the Study:
- To achieve consensus on a core minimum data set for the Women's Health Technology Coordinated Registry Network (WHT-CRN).
- To identify critical data elements for evaluating the safety and effectiveness of contraceptive medical products.
- To lay the foundation for a national infrastructure to capture contraceptive performance data.
Main Methods:
- A Delphi survey method was employed with a multistakeholder expert panel.
- Anonymously administered surveys were conducted over a 6-month period, with iterative analysis and discussion.
- Consensus was achieved through multiple rounds of surveys and conference calls.
Main Results:
- Twenty-three experts participated in the Delphi process, with high participation rates (83% and 100% in rounds 1 and 2).
- Consensus was reached on 121 core data elements.
- These elements encompass a comprehensive range of information, including patient history, procedure details, product specifics, complications, and outcomes related to safety and effectiveness.
Conclusions:
- A consensus-based core data set was successfully established by the WHT-CRN expert group.
- This data set will facilitate the study of current and future contraceptives.
- The identified data elements are crucial for informing patient and provider decisions and improving the understanding of contraceptive safety and effectiveness.

Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...
Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
Pharmacovigilance
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
In some cases, there...
Prescription, Nonprescription and Orphan Drugs
The misuse and addiction to prescription drugs is a growing problem that can affect people of all age groups, specifically teenagers. This can happen when prescription medications are used in ways not intended by the prescriber, such as taking someone else's prescription or using medication for...
Drug Administration and Therapy Phases: Overview
The pharmaceutical phase focuses on leveraging the physicochemical properties of the drug to design and manufacture an effective product. Variants include orally administered tablets or capsules, topical creams or ointments, and parenteral-delivery solutions or emulsions.
