Experience with SI units in biochemistry.

Area of Science:

• Medical Laboratory Science
• Clinical Pathology
• Healthcare Administration

Background:

• The transition to Système International d'Unités (SI) for laboratory measurements was mandated for standardization.
• Previous conventional units of measurement presented challenges in international scientific communication and data comparison.

Purpose of the Study:

• To evaluate the feasibility and impact of implementing SI units in community hospital laboratories.
• To assess the medical staff's adaptation and the associated costs of adopting the SI system.

Main Methods:

• Instituted SI units for laboratory measurements starting January 1, 1975, at two community hospitals.
• Conducted pre-implementation education, distributed conversion materials, and updated laboratory systems.
• Surveyed medical staff regarding conversion habits and perceived difficulty after six months.

Main Results:

• The total cost for implementation was under $200.
• After six months, 16% of medical staff no longer converted SI units, while 78% occasionally converted.
• 25% found the changeover difficult, 49% found it a nuisance, and 26% found it easy.
• Patient safety was not compromised during the transition.

Conclusions:

• The adoption of SI units in community hospitals is feasible, cost-effective, and safe for patients.
• Medical staff adaptation to SI units requires time and support, with varying degrees of difficulty.
• Standardized laboratory measurements using SI units improve data consistency and reduce potential for errors.
