The Increasing PV Obligations of Scientific Literature
Scientific literature is a significant source of information for the monitoring of the safety profile of medicinal products, particularly in relation to the detection of new safety signals or emerging safety issues. However, the monitoring of literature with respect to pharmacovigilance is a huge undertaking, involving investment of excessive time, effort and cost for sifting through high volumes of multi-disciplinary journals.
With global regulations constantly shifting and with the level of scientific literature progressively increasing, pharmacovigilance teams are under continued pressure to create literature strategies that are both comprehensive and flexible. Therefore, establishing the right process from the outset is fundamental to ensure that compliance deliverables are met. Here are 5 points to consider when developing a literature review process:
1. Where to look
The type of medicinal product (drug, medical device) should determine what type of database to use however, most well-known databases such as Medline or Embase cover most scientific and medical journals.
2. Developing a search strategy
Author abstracts are not always consistent in the choice of words relating to pharmacovigilance concepts thus, applying a search strategy will help to eliminate background noise, giving focus to scientific publications that are most relevant to pharmacovigilance. It is important to know your product and what you are trying to achieve; the highest recall for a search would be to enter the medicinal product name and active substance name (in all their variants) only. In practice, additional text can be added to increase precision. It is always good practice to retain a record of the search construction, the database used and the date the search was run.
3. Creating a process
Following a decision on the type of database to be used and the search strategy, consideration should be given to the details of the literature process such as; the screening process, implementing quality review checks to ensure that the primary reviewer is identifying the relevant articles, storage systems such as repositories, methods for the ordering of full articles and the management of translations and so on. Once a process has been established it should be clearly outlined in an SOP.
4. Testing phase
Initial testing should be conducted to check that relevant records are not omitted. Term selection should be relevant to the database used and the subject of the search and/or medicinal product. Recorded confirmation that the search results have been tested will assist in demonstrating that there is a systematic approach to collecting information about suspected adverse reactions from literature sources.
5. Appropriately trained staff
It is expected that the person reviewing the results of a search is trained to identify articles of relevance. A common issue in selecting relevant articles from the results of a search is that often this process is conducted for the purposes of identification of ICSRs only. Whereas the review should also be used for collating articles of safety information for example, to support PSURs. Having an appropriately trained team will mitigate the risk of missing important information.
As literature is the one of the largest sources available for the collection of safety information it is crucial that careful planning is allotted to the development of an adequate process.
