Underreporting of Reported (S)AEs
Underreporting of Reported (S)AEs
| Type of indicator | Risk |
|---|---|
| Risk Category | Safety |
| Golden KRI | YES |
| Therapeutic Area | General |
| IF Risk-Event | (S)AE underreporting happens |
| DUE TO Risk Causes | Various reasons |
| THEN Risk Impact MAY RESULT | Poor data integrity, jeopardy of Subject safety |
| Risk Indicator | Underreporting of Reported (S)AEs |
| Metric | Percent of Difference of Rate of (S)AE For Site And Average Rate For Study (Negated) |
| Unit | % |
| What level should be measured | Study, Country, Site |
| Purpose | Monitoring safety is critical in a clinical trial. By monitoring the number of (S)AEs reported per participant visit and comparing between sites, it is possible to detect sites that are either reporting unusually high or low levels of (S)AEs. These outlier sites need investigation as it may be that the protocol is not being followed (e.g., the same AE is being reported multiple times, multiple AEs are being reported as one AE), or that the trial participants at those sites are generally healthier (or less healthy) than at other sites. Investigation is needed to determine if further follow-up and correction is required. |
| Description | This KRI monitors whether a site is reporting a relatively low number of (S)AEs compared with other sites in the trial. The KRI alarms if the rate is too high (or low) compared with other sites. |
| Formula | Calculate the percent of absolute difference between Rate of AE (at the study level) and Rate of AE (in entity) relatively to the former. KEITH QUESTION: Isn't this the same KRI as over-reporting? It's just a different threshold on the same KRI i.e. one KRI with an upper and lower threshold? |
| Suggested Thresholds - High | <70 % |
| Suggested Thresholds - Medium | <80 % |
