Optimizing chemotherapy clinic pharmacy operations: a scheduling approach for efficient medication preparation

The quality of service in a chemotherapy clinic is contingent upon the meticulous preparation of medicines, which must be served in the right quantities and on time. Considering the high hazards and costs associated with chemotherapy drugs, it becomes imperative to optimize their preparation. A scheduling method was therefore developed for the manufacture of drugs in a chemotherapy clinic, aimed at reducing patient waiting times and minimizing preparation costs. This involves the utilization of a linear programming model for scheduling approximation, coupled with a lexicographical approach. The objective is to minimize both the maximum task delay during a production day and the associated costs of raw materials and overall delays. The obtained solution is then reconstructed to explicate the scheduling details and establish a timetable in adherence to clinic constraints. This reconstruction facilitates not only the reduction of delays but also enhances productivity at reduced costs. This scheduling method contributes to a more efficient and cost-effective workflow in chemotherapy clinics, ultimately leading to improved patient care and resource utilization.
