Area of Science:

  • Hospital Pharmacy
  • Medication Safety
  • Nursing Practice

Background:

  • Danish hospitals commonly use ward-based medication supply systems managed by nursing staff.
  • This study aimed to quantify dispensing errors and identify associated risk factors in these systems.

Purpose of the Study:

  • To determine the frequency of medication dispensing errors in hospital wards.
  • To identify key risk factors contributing to these errors.

Main Methods:

  • A cross-sectional study was conducted across five hospital wards.
  • Random samples of dispensed medications were compared against original drug orders.

Main Results:

  • The overall dispensing error rate was 1.8% (42 errors out of 2360 opportunities).

  • Omissions constituted 55% of all detected errors.
  • Errors were significantly associated with scheduled administration times, ward type, and the quantity of doses dispensed.

    • Conclusions:

    • Approximately 1.8% of medications are dispensed with errors, with omissions being prevalent.
    • The number of nurses involved in dispensing did not impact the error rate.
    • Reducing poly-pharmacy and analyzing low-error ward procedures may decrease dispensing errors.
