Errors remaining in unit dose carts after checking by pharmacists versus pharmacy technicians.

The accuracy of pharmacists and pharmacy technicians in checking unit dose carts was compared. One-half of the unit dose patient medication drawers, for a 92-bed medicine service in a 450-bed teaching hospital, were checked by pharmacy technicians and the remaining by pharmacists. These drawers then were checked again to determine the number and type of checking errors committed by technicians and pharmacists. During the 10-day study, carts checked by pharmacists contained over twice as many errors (1.85%) as similar carts checked by technicians (0.87%). The results suggest that pharmacy technicians could probably be trained to perform the cart-checking task in unit dose drug distribution systems. Time-extended studies should be done to determine if technician performance is maintained after the novelty of the task wears off.
