title: [Cost-benefit analysis of a semi-automated process in the preparation of unit-doses by the Pharmacy Department].
abstract: 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.
  
  
  CONCLUSIONS
  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.
