Multidose vials versus single-dose vials: a study in sterility and cost-effectiveness.
A total of 197 multidose injectable vials were collected from 10 different nursing stations and evaluated for sterility. Experimental contamination studies were undertaken, and the cost-effectiveness of multidose vials was compared with that of single-dose vials. Our results showed that bacterial contamination of multidose injectable vials was not a significant hazard; in addition, contrary to common belief, the use of multidose vials was not always successful as a cost-containment measure.
