Author Information
Author(s): Thomas G. Pellar, James F. Tuckerman, A. Ralph Henderson
Primary Institution: University Hospital (University of Western Ontario)
Hypothesis
Can a standardized MUMPS program reduce calculation errors in laboratory sample dilution?
Conclusion
The implementation of a new dilution routine has completely eliminated serious and trivial errors in sample dilution calculations.
Supporting Evidence
- Initial error rates for serious errors were 8% and trivial errors were 4%.
- Post-implementation surveys showed no serious or trivial errors.
- The program was accepted and used by all laboratory staff with little hesitation.
Takeaway
This study shows that using a special computer program can help lab workers avoid mistakes when mixing samples.
Methodology
The study involved implementing a MUMPS program for dilution calculations and tracking errors before and after its introduction.
Limitations
The study does not address potential errors in other laboratory processes outside of dilution calculations.
Participant Demographics
Laboratory staff at University Hospital, London, Ontario, Canada.
