In pharmacovigilance, solicited reports refer to reports of adverse events or other drug-related problems that are actively requested, collected, and recorded as part of a structured data collection process. These reports differ from spontaneous reports, which are unsolicited and initiated by healthcare professionals, patients, or caregivers based on observations in routine clinical practice.
Key Characteristics of Solicited Reports:
- Structured Data Collection: Solicited reports are gathered through organized and planned data collection systems. These can include clinical trials, patient support programs, post-marketing surveillance studies, or other organized monitoring programs.
- Active Request for Information: Unlike spontaneous reports, where the information is volunteered, solicited reports are generated through active questioning about specific adverse events or outcomes.
- Part of a Defined Study or Program: These reports are typically part of a specific study protocol or a risk management plan. They are gathered as part of ongoing safety monitoring commitments made to regulatory authorities.
- Use in Safety Evaluation: Solicited reports are used to evaluate the safety profile of a drug. They can provide valuable data on adverse events, especially in controlled environments like clinical trials.
- Consistency in Data Collection: Since solicited reports are part of a structured approach, they often provide more consistent and comprehensive data compared to spontaneous reports.
- Regulatory Compliance: Solicited reporting can be a regulatory requirement for certain drugs, especially those with known safety concerns or those that are newly approved and under close safety scrutiny.
Examples of Solicited Reports Sources:
- Clinical Trials: Data collected from participants during a clinical trial, including both efficacy and safety data.
- Post-Marketing Surveillance Studies (Phase IV Trials): Studies conducted after a drug is approved and marketed, aimed at understanding long-term safety and effectiveness.
- Patient Registries: Specific databases designed to track outcomes in patients with particular conditions or treatments.
- Drug-Specific Programs: Such as patient support or drug monitoring programs where patients are regularly contacted and asked about their experiences with the drug.
Importance in Pharmacovigilance:
Solicited reports play a critical role in pharmacovigilance by providing systematic and detailed data on drug safety. They complement spontaneous reports by offering a more controlled and comprehensive view of potential adverse effects and help in the ongoing evaluation of the risk-benefit balance of medicinal products. However, because the data from solicited reports are collected under specific conditions or protocols, they might not fully represent the broader patient population or real-world use. Therefore, both solicited and spontaneous reports are important for a complete understanding of a drug’s safety profile.
