Certainly, the size of the hospital, or more precisely
the number of dispensed annual doses, matters. Keeping costs constant, return on investment within 10 years
was achieved with annual doses of at least 1.75 million.
However, it is likely that smaller hospitals would have
lower expenses as well. Also, the fact that bar coding of
unit-dose medications by manufacturers is now mandated
implies that a portion of the costs measured in this study (that associated with repackaging) might be
avoided or reduced
