Step 1: Define the Research Question
The first step in conducting a systematic literature search is to clearly define the research question. In pharmacovigilance, the question often revolves around identifying new safety information for a specific drug or class of drugs. For example:
What are the new adverse effects associated with Drug X?
Are there any reports of drug-drug interactions involving Drug Y?
Step 2: Develop a Search Strategy
A well-thought-out search strategy is essential for ensuring that all relevant literature is captured. This strategy should include:
Keywords and Phrases: Identify relevant keywords, synonyms, and phrases that relate to the research question. Consider variations in spelling and terminology, especially in international contexts.
Boolean Operators: Use Boolean operators (AND, OR, NOT) to combine keywords effectively and refine the search.
Filters and Limits: Apply filters and limits to narrow down the search results. Common filters include publication date, language, study type, and population.
Database Selection: Choose the appropriate databases to search, based on the scope of the research question and the drug in question. In some cases, it may be necessary to search multiple databases to ensure comprehensive coverage.
Step 3: Execute the Search
With the search strategy in place, the next step is to execute the search on the selected literature review platform. This involves entering the search criteria into the platform, applying the relevant filters, and running the search across the chosen databases.
Step 4: Review and Refine Search Results
After executing the search, review the results to ensure that they are relevant and comprehensive. This step may involve refining the search strategy, such as adjusting keywords, adding new filters, or excluding irrelevant studies.
Screening: Use the platform’s screening tools to quickly assess the relevance of each result. Some platforms offer AI-driven screening features that can help prioritize the most relevant studies.
Duplicate Removal: Ensure that duplicate entries are identified and removed, particularly when searching across multiple databases.
Step 5: Document the Search Process
Documentation is a critical aspect of regulatory compliance. The entire search process, including the search strategy, keywords used, databases searched, and the number of results, should be thoroughly documented.
Search Log: Maintain a detailed search log that includes the date and time of the search, the search strategy, and any modifications made during the process.
Audit Trail: Use the platform’s audit trail features to document the search process, ensuring that it can be reviewed and verified by regulatory authorities if needed.
Exporting Results: Export the search results into a format that can be easily shared and reviewed by the pharmacovigilance team. Common formats include Excel, CSV, and PDF.
4. Assessing and Analyzing the Literature
Once the relevant literature has been identified, the next step is to assess and analyze the findings. This involves critically evaluating the studies to determine their relevance, quality, and impact on the drug’s safety profile.
Step 1: Critical Appraisal of Studies
Critical appraisal involves evaluating the methodology, results, and conclusions of each study to determine its validity and applicability to pharmacovigilance.
Study Design: Assess the study design to ensure it is appropriate for answering the research question. Randomized controlled trials (RCTs) and systematic reviews are generally considered high-quality evidence.
Bias and Confounding: Evaluate the risk of bias and potential confounding factors in the study. Studies with a high risk of bias may not provide reliable evidence.
Relevance to Pharmacovigilance: Determine the relevance of the study’s findings to the specific pharmacovigilance question. Not all studies will provide directly applicable information, so it’s important to focus on those that do.
