Resource Allocation: Literature monitoring is resource-intensive, requiring skilled personnel to review and interpret literature. Many companies struggle with allocating sufficient resources to this task while managing other pharmacovigilance activities.
Timeliness: Regulatory bodies often require that ADRs identified in the literature be reported within a specific timeframe. Delays in literature monitoring can lead to non-compliance and regulatory action.
Best Practices for Achieving Compliance in Literature Monitoring
To overcome these challenges and achieve compliance with literature monitoring, pharmaceutical companies can adopt several best practices:
1. Develop a Comprehensive Literature Monitoring Plan
A well-structured literature monitoring plan is the foundation of compliance. This plan should outline the following:
Scope: Define the scope of literature monitoring, including the types of literature to be monitored (e.g., clinical trials, case reports, reviews) and the databases and journals to be included.
Frequency: Determine how often literature searches will be conducted (e.g., weekly, monthly) based on the product's risk profile and regulatory requirements.
Search Strategy: Develop a robust search strategy that includes relevant keywords, MeSH terms, and Boolean operators to capture all relevant literature.
Roles and Responsibilities: Assign clear roles and responsibilities for literature monitoring, including who will conduct searches, review articles, and report findings.
2. Utilize Technology and Automation
Given the volume of literature to be reviewed, leveraging technology and automation can significantly enhance compliance:
Automated Literature Searches: Use automated literature search tools to conduct regular searches across multiple databases. These tools can help ensure that no relevant literature is missed and that searches are conducted consistently.
Artificial Intelligence (AI) and Machine Learning (ML): Implement AI and ML algorithms to filter and prioritize literature based on relevance and potential safety signals. These technologies can also assist in data extraction and interpretation, reducing the risk of human error.
Natural Language Processing (NLP): NLP can be used to process and analyze unstructured data in literature, such as free-text abstracts and full-text articles, to identify potential ADRs.
Wearable Technology: Integrating data from wearable devices into literature monitoring can provide real-time insights into drug safety and efficacy, particularly in post-market surveillance.
3. Ensure Data Integrity
Data integrity is paramount in literature monitoring. To ensure compliance:
