Evaluation of the US Food and Drug Administration Sentinel Analysis Tools in Confirming Previously Observed Drug-Outcome Associations: The Case of Clindamycin and Clostridium difficile Infection

    Basic Details
    Medical Product
    Health Outcome(s)
    clostridium difficile

    The Food and Drug Administration's Sentinel System developed parameterized, reusable analytic programs for evaluation of medical product safety. Research on outpatient antibiotic exposures, and Clostridium difficile infection (CDI) with non-user reference groups led us to expect a higher rate of CDI among outpatient clindamycin users vs penicillin users. The authors evaluated the ability of the Cohort Identification and Descriptive Analysis and Propensity Score Matching tools to identify a higher rate of CDI among clindamycin users. This evaluation produced an expected result and identified several potential enhancements to the Propensity Score Matching tool. This study has important limitations. CDI risk may have been related to factors other than the inherent properties of the drugs, such as duration of use or subsequent exposures.
