Predictors of unit-level medication administration accuracy: microsystem impacts on medication safety

Area of Science:

• Nursing Science
• Patient Safety Research
• Healthcare Quality Improvement

Background:

• Nurses play a critical role in preventing medication errors during administration.
• Direct observation is a key method for assessing medication administration accuracy and safe practices.

Purpose of the Study:

• To investigate unit-level predictors influencing medication administration accuracy.
• To identify factors that impact nurses' adherence to safe medication administration practices.

Main Methods:

• A cross-sectional study design utilizing direct observation.
• Data collected from 124 adult patient care units, covering 15,600 medication doses.
• Analysis of unit characteristics and registered nurse (RN) hours of care.

Main Results:

• Distractions and interruptions were identified as primary causes of safe practice deviations.
• Unit characteristics and RN hours of care significantly influenced safe practices and medication administration accuracy.
• A 5% reduction in safe practice deviations could lead to a 46% decrease in medication errors, independent of staffing.

Conclusions:

• Enhancing nurses' adherence to safe medication administration practices is crucial for improving accuracy.
• Unit characteristics and staffing levels are modifiable factors that can significantly impact medication administration safety.
• Targeting safe practice deviations offers a promising strategy for substantial error reduction.
