Abstract

Purpose
Many studies using a common data model (CDM) have recently been reported. This study aims to determine the prevalence and clinical characteristics of vancomycin-associated adverse drug reactions (ADRs) using CDM and to identify its usefulness in ADRs.
Methods
This study was conducted from the OMOP-CDM (Observational Medical Outcomes Partnership-CDM) version 5.3 database of Convergence Medical Institute of Technology, Pusan National University Hospital. The study cohort was defined as patients who had taken vancomycin for more than 7 days and had normal blood tests within 1 week before administration. ADRs included neutropenia, eosinophilia, thrombocytopenia, drug-induced liver injury, and acute kidney injury.
Results
The most frequent ADR to vancomycin was thrombocytopenia (18.32%), followed by neutropenia (7.81%), acute kidney injury (5.85%), eosinophilia (5.32%), and drug-induced liver injury (4.15%). The baseline hematologic values were closer to the reference value of ADR definition in patients who developed ADRs than those without ADRs, even though the values were within the normal range. Acute kidney injury was common in males and the patients had high vancomycin trough concentrations. The period of vancomycin exposure was longer in the ADR groups. The incidence of new adverse reactions was highest for thrombocytopenia, and it was higher in males than in females, except for neutrophilia.
Conclusion
This study examined the prevalence, incidence rates, and clinical features of vancomycin-associated ADR using CDM. A CDM could serve as a significant data source for monitoring ADRs.
