Assessing the impact of an electronic chemotherapy order verification checklist on pharmacist reported errors in oncology infusion centers of a health-system.

Purpose: Chemotherapies are medications with narrow therapeutic indices and potential for severe adverse events that account for at least 1 to 3% of medication errors in all adult and pediatric oncology patients. The use of an electronic chemotherapy order verification (ECOV) checklist can standardize the steps of chemotherapy verification by pharmacists, which can potentially increase medication error detection at the point of dispensing. This study evaluated the implementation of a standardized chemotherapy order verification checklist on pharmacist error reporting, particularly good-catches or near-misses type errors.
Methods: This retrospective, quasi-experimental, pre-/post-analysis of internal voluntary medication errors reported from 12 University Hospitals Seidman oncology infusion centers from June 2022 through December 2022. Error reports, categorized based on severity, were compared pre/post-implementation of the ECOV checklist.
Results: A total of 62 and 71 cases of medication errors were reported in the pre-intervention and post-intervention periods, respectively. The rate of pharmacy reported medication errors was 2.4 times greater in the post-intervention period of the ECOV checklist ( p  < 0.006). Pharmacy reported errors increased among all error severities reported. However, the finding did not deduce a statistically significant difference ( p  < 0.244).
Conclusion: This study demonstrates the effectiveness of implementing the ECOV checklist in increasing the rate of pharmacy reported medication errors. The checklist was designed to complement existing pharmacist workflow and provide a source of documentation for steps of sequential pharmacist evaluation.
