Introduction
Duplicate reports are a regular challenge in pharmacovigilance case processing, encountered by professionals.
This blog aims to gain a understanding of duplicates and their global impact on pharmacovigilance datasets.
We’ll discuss methods for:
- detecting
- confirming, and
- managing duplicate cases, offering guidance for organizations navigating this issue.
What Are Duplicates?
Duplicates refer to where a case file exists in many versions, that contains similar information that from the same source.
In other words, a duplicate referred as a report of the same individual. And the case submitted by a primary source, detailing suspected adverse reactions.
It associated with one or more medicinal products for a specific patient at a given time.
Managing duplicate reports generally involves three key steps:
- Detection of Duplicates: Identifying potential duplicates within the dataset.
- Confirmation of Duplicates: Verifying that the identified reports indeed refer to the same case.
- Management of Duplicates: Taking appropriate actions to handle the duplicates effectively.
Possibilities of Duplicates
Despite the efforts in reporting, duplicate submissions are an inevitable aspect of pharmacovigilance.
An individual case may reported by different sources through various channels. It often leading to inconsistencies in how the information is processed.
This complexity makes it challenging to identify these reports as duplicates.
To effectively manage duplicate reporting, organizations must install robust mechanisms for detection.
Rather the system used for collecting and consolidating Individual Case Safety Reports (ICSRs).
Common Causes of Duplicate Reports
Some frequent scenarios that lead to duplicate reports include:
- A consumer and a healthcare professional independently reporting the same adverse reaction.
- Multiple healthcare professionals treating the same patient submitting reports for the same reaction.
- Submission to both the marketing authorization holder and a competent authority within a Member State.
- Literature reports detailing the same reaction occurrence for generic medications.
“In the world of data, duplicates are the shadows that obscure the truth.”
Challenges in finding duplicates
Identifying potential duplicates in individual case collections presents significant challenges.
Often, duplicates submitted by many sources or processed through various reporting systems, resulting in discrepancies in case information.
For example:
- Different terminologies may used to code the same incident.
- Patient details may different, due to differing personal data protection regulations across Member States.
- Additionally, while coding the absence of an international standard for medicinal product identification can lead to inconsistencies.
This complexity necessitates careful and systematic approaches to effectively manage and identify duplicates.
Impact of Duplicates
- Duplicate reports of suspected adverse reactions can create significant challenges for analyzing signals in pharmacovigilance databases.
- They can complicate the interpretation of safety data and hinder effective decision-making in drug safety assessments.
How to Avoid Duplicates?
- Routine Screening: Databases should be regularly screened to detect and eliminate duplicate cases.
- Collaborative Management: Detection and handling of duplicates by competent authorities and marketing authorization holders are crucial for effective case management.
- Regular Review: Databases should be often reviewed to identify duplicates. Every newly received Individual Case Safety Report (ICSRs) treated as a chance of potential duplicate before letting in to the database.
- Linking Reports: Establishing a system to populate ‘Linked Reports’ can help maintain clarity and organization within the dataset.
Managing Duplicates
Duplicate cases are typically managed by merging two or more reports into a single master case. This process can follow one of two approaches:
- Allocation of a Master Case is based on one of the existing cases to merge.
- Creation of a Master Case is by combining all information from the subordinate duplicate cases, ensuring never missed..
Key Takeaways
Duplicates can be prevented by regular screening and thorough review of ICSR case management.
Establishing a system for linking related reports can enhance clarity and organization within pharmacovigilance datasets.
Duplicates are not just another case processed, it hinders your productivity, public safety delays, doubles the work.
Duplicates ca n be effectively managed and reduced by the way beginning at book-n process.
