Objective: To determine in monetary terms the effect of implementing a semi-automated procedure for preparation of drugs for unit dose distribution.
Methods: The current net value was estimated for three different flows involved in the evaluation of semi-automated drug storage and retrieval systems used in the unit dose distribution area in a hospital: capital investment, staff costs and structural costs related to physical space occupied.
Results: Implantation of the new work procedure produced an annual saving of 32,390 euro in staff costs and 5,645 euro in structural costs. Global cash flow has been estimated in -96,565 euro for a five year amortization period, with a benefit/cost ratio of 2.19.
Conclusion: Replacement of traditional unit dose cart filling systems by a semi automated procedure presents a positive benefit/cost ratio and initial investment is paid off in 44 months.
