Spontaneous Case Reports
- Definition:
  - Healthcare professionals report observed adverse drug interactions to regulatory agencies or pharmacovigilance centers.
- Advantages:
  - Real-World Data: Reflects actual clinical scenarios.
  - Early Warning Signals: Can identify rare or unexpected interactions.
- Limitations:
  - Underreporting: Not all cases are reported.
  - Lack of Control Group: Difficult to establish causality.
- Process:
  - Reporting Systems: Use of forms or online systems to submit reports.
  - Data Analysis: Agencies analyze reports for patterns and signals.
Record Linkage Studies
- Definition:
  - Linking data from various databases (e.g., prescription records, hospital admissions) to identify associations between drug use and adverse events.
- Advantages:
  - Large Sample Sizes: Access to extensive population data.
  - Longitudinal Analysis: Can study long-term effects.
- Limitations:
  - Data Quality: Accuracy depends on the quality of records.
  - Confounding Factors: Potential for bias without randomization.
- Process:
  - Data Collection: Gathering information from electronic health records.
  - Statistical Analysis: Using epidemiological methods to identify associations.
