Background: The ever-increasing complexity and demand for antineoplastic therapy necessitates innovative solutions to improve the accuracy and safety of drug preparation. Objective: To evaluate the utilization of an advanced robotic chemotherapy drug compounding system (APOTECAchemo) at a Community Cancer Center (CCC), examining accuracy, efficiency, and staff perceptions. Methods: This single-center, retrospective study evaluated the preparation of 7 intravenous (IV) antineoplastics at a CCC over a 1-year period. We compared manual methods with the APOTECAchemo system. The primary measure of accuracy was the absolute drug error percentage, with a comparison of pass and fail rates. Secondary endpoints included the overall use of APOTECAchemo for all IV antineoplastic preparations and average preparation times. An end-user satisfaction survey gathered feedback from pharmacists and pharmacy technicians. Results: A total of 8210 doses were prepared at the CCC, with 52.1% compounded by APOTECAchemo and 47.9% manually. Of these, the CCC prepared 5526 doses of the 7 routinely compounded antineoplastics. APOTECAchemo prepared 3851 (69.7%) doses, while manual compounding accounted for 1675 (30.3%) doses. The average absolute drug error was 1.44% (95% CI, 1.35-1.53) with robot compounding versus 1.17% (95% CI, 1.03-1.32) with manual ( P < 0.001). The overall failure rate was 0.72%. There were 25 failed doses (0.45%), with 8 (0.2%) failures attributed to APOTECAchemo and 17 (1%) to manual compounding ( P < 0.001). The average dose preparation time was longer with APOTECAchemo compared with manual methods. The end-user satisfaction survey indicated a positive reception toward APOTECAchemo. Conclusions: Our study demonstrates the successful implementation, extensive utilization, and high accuracy of both APOTECAchemo and manual compounding methods in the preparation of routinely administered antineoplastics at a CCC.
