To identify differences in the incidence and severity of adverse drug events (ADEs) due to CNS depressant drugs among pediatric patients with and without surgery. The Japan Adverse Drug Events Study was a cohort study enrolling pediatric inpatients. Potential ADEs were identified by onsite review of medical charts, incident reports, and prescription queries. Two independent physicians classified ADEs and severity. We compared the incidence and characteristics of ADEs between pediatric patients with surgery (surgery group) and without surgery (non-surgery group). We evaluated severity of ADEs due to CNS depressant drugs among both groups. We enrolled 944 patients, 234 in surgery group and 710 in non-surgery group. A total of 480 ADEs due to any drugs occurred in 225 patients. Among 81 ADEs due to CNS depressant drugs, 42 ADEs were in surgery group, whereas 39 were in non-surgery group. The risk of fatal or life-threatening ADEs due to CNS depressant drugs was significantly higher than other drugs (12% vs. 2%, p < 0.001). In the surgery group, anesthetics led to 2 fatal or life-threatening, 8 serious, and 30 significant ADEs, whereas in the non-surgery group anesthetics led to 2 fatal or life-threatening, 5 serious, and 4 significant ADEs. Anesthetics were higher risk in the non-surgery group (p = 0.049). The risks of fatal and life-threatening ADEs were significantly higher with CNS depressant drugs than other drugs. Pediatric patients without surgery have higher risks of fatal or life-threatening ADEs due to anesthetics than those with surgery.
