[Cost-benefit analysis of the implementation of automated drug-dispensing systems in Critical Care and Emergency Units].
OBJECTIVE
To determine monetary impact when traditional drug floor stocks are replaced by Automated Drug Dispensing Systems (ADDS) in the Medical Intensive Care Unit, Surgical Intensive Care Unit and the Emergency Room.


METHODS
We analysed four different flows considered to be determinant when implementing ADDS in a hospital environment: capital investment, staff costs, inventory costs and costs related to drug use policies.


RESULTS
Costs were estimated by calculation of the current net value. Its analysis shows that those expenses derived from initial investment are compensated by the three remaining flows, with costs related to drug use policies showing the most substantial savings. Five years after initial investment, global cash-flows have been estimated at 300.525 euros.


CONCLUSIONS
Replacement of traditional floor stocks by ADDS in the Medical Intensive Care Unit, Surgery Intensive Care Unit and the Emergency Room produces a positive benefit/cost ratio (1.95).
