Environmental variables and errors in the preparation and administration of medicines

Area of Science:

• Healthcare quality and safety
• Clinical pharmacy practice
• Environmental health in hospitals

Background:

• Medication errors pose a significant risk to patient safety in healthcare settings.
• Environmental factors in clinical settings are increasingly recognized as potential contributors to medical errors.
• Optimizing the hospital environment is crucial for ensuring safe medication practices.

Purpose of the Study:

• To investigate the association between environmental conditions and medication errors.
• To identify specific environmental factors influencing the preparation and administration of antibacterial medications.
• To assess the impact of noise, illumination, humidity, temperature, and physical space on medication safety.

Main Methods:

• An observational, cross-sectional study was conducted in two clinical units from August to December 2014.
• A sample of 265 medication doses was observed across different shifts.
• Environmental conditions (noise, illumination, humidity, temperature, physical space) were measured during medication preparation and administration.

Main Results:

• Inadequate physical space (3.8m²) was noted in one unit.
• Illumination, temperature, and noise levels fluctuated significantly across shifts and units, often exceeding recommended hospital standards.
• While environmental variations were observed, illumination and noise levels did not show a statistically significant correlation with dose errors or incorrect medication selection (p > 0.05).

Conclusions:

• Environmental variables, including physical space, illumination, temperature, and noise, may increase the likelihood of medication errors.
• The findings suggest that suboptimal environmental conditions can compromise medication safety during preparation and administration.
• Interventions to improve the hospital environment are warranted to reduce medication errors.
