Abstract
Purpose: To investigate the risk factors associated with medication errors and to compare the
incidence and types of voluntarily reported medication errors among adult intensive care unit (ICU) and
non-ICU patients at King Abdulaziz Medical City, Riyadh, Saudi Arabia.
Methods: The design of this study was retrospective. All voluntarily reported medication errors involving
adult patients (≥ 18 years) who were admitted into King Abdulaziz Medical City during the study period
(January 2012 to June 2013) were included in the study. Reported medication errors were classified as
ICU or non-ICU errors. Medication errors were also classified according to the node of medication use,
harm category, and type of medication errors.
Results: A total of 31,399 patients admitted into the hospital were included in the study, with 1,966 (6
%) admitted into the ICU and 29,433 (94 %) admitted into the non-ICU units. Overall, the incidence of
medication errors was 1.2 % (390/31,399), 1. Over half of the errors were administration-related (51 %).
The incidence of medication errors was 5.5 % (108/1,966) in ICU compared with 0.96 % (282/29,433) in
non-ICU units (p < 0.001. In both settings, prescribing errors, delay in drug administration and
dispensing extra dose were the most common medication errors. Higher risk for medication errors was
significantly associated with admission into ICU vs. non-ICU units [OR = 5.24, 95 % CI: (4.12, 6.65); p <
0.001] and with patients’ age ≥ 60 vs. < 60 years [OR = 1.48, 95 % CI: (1.19, 1.83); p < 0.001].
Conclusion: Medication errors are common in the health facility and occur during all stages of
medication use from prescribing to administration. Higher risk for medication errors is associated with
admission into the ICU and with patients’ age ≥ 60. Physician, pharmacists, and nurses need to be
vigilant, up-to-date, and continuously trained to reduce the incidence of medication errors.
