PURPOSE: To investigate if differences in antecedents of severe and nonsevere
medication errors exist. DESIGN: A longitudinal study of 6 months of data from
279 nursing units in 146 randomly selected hospitals in the United States (US).
METHODS: Antecedents of severe and nonsevere medication errors included work
environment factors (work dynamics and RN hours), team factors (communication
with physicians and nurses' expertise), person factors (nurses' education and
experience), patient factors (age, health status, and previous hospitalization),
and medication-related support services. Generalized estimating equations with a
negative binomial distribution were used with nursing units as the unit of
analysis. FINDINGS: None of the antecedents allowed predicting both types of
medication errors. Nurses' expertise had a negative and medication-related
support services had a positive association with nonsevere medication errors.
Nurses' educational level had a significant nonlinear relationship with severe
medication errors only: As the percentage of unit BSN-prepared nurses increased,
severe medication errors decreased until the percentage of BSN-prepared nurses
reached 54%. In contrast, RN experience had a statistically significant
relationship with nonsevere medication errors only and nursing units with more
experienced nurses reported more nonsevere medication errors. CONCLUSIONS: Severe
and nonsevere medication errors might have different antecedents. CLINICAL
RELEVANCE: Error prevention and management strategies should be targeted to
specific types of medication errors for best results.
