Multidose vials versus single-dose vials: a study in sterility and cost-effectiveness
Abstract:
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.
Insights
Multidose injectable vials showed minimal bacterial contamination risk in nursing stations. However, their use as a cost-saving measure compared to single-dose vials was not consistently effective.
Area of Science:
- Microbiology
- Healthcare Economics
- Pharmacy Practice
Background:
- Multidose vials are commonly used in healthcare settings.
- Concerns exist regarding microbial contamination and cost-effectiveness.
Purpose of the Study:
- To assess the sterility of multidose injectable vials in nursing stations.
- To evaluate the cost-effectiveness of multidose vials versus single-dose vials.
Main Methods:
- Collected 197 multidose vials from 10 nursing stations for sterility testing.
- Conducted experimental contamination studies.
- Compared the cost-effectiveness of multidose and single-dose vials.
Main Results:
- Bacterial contamination of multidose vials was not found to be a significant hazard.
- The use of multidose vials did not consistently prove to be a cost-containment strategy.
Conclusions:
- Multidose vials appear safe from a contamination perspective in this setting.
- Healthcare facilities should carefully evaluate cost-saving claims associated with multidose vial usage.
