Nursing staffing, nursing workload, the work environment and patient outcomes

Area of Science:

• Nursing
• Patient Safety
• Healthcare Management

Background:

• Inadequate nurse staffing levels, particularly fewer registered nurses (RNs), are a persistent concern in healthcare settings.
• Increased workload and environmental instability within nursing units can potentially compromise patient care quality.
• Previous research suggests a correlation between nursing work environments and patient outcomes, but further investigation is warranted.

Purpose of the Study:

• To investigate the relationship between nurse staffing levels, workload, nursing unit environment, and patient outcomes on medical/surgical units.
• To identify specific factors within the nursing unit environment that contribute to adverse patient events.
• To provide evidence-based insights for improving patient safety through optimized nursing practices and environments.

Main Methods:

• A mixed-methods study was employed, integrating quantitative longitudinal data spanning five years with qualitative primary data collection.
• Data analysis focused on correlating nurse staffing ratios (specifically RNs), reported workload, and unit environmental stability with patient safety incidents.
• Patient outcomes, including falls and medication errors, were systematically tracked and analyzed.

Main Results:

• A significant association was found between reduced registered nurse (RN) staffing and an increase in patient falls.
• Higher nurse workload and unstable nursing unit environments were strongly correlated with a greater incidence of medication errors.
• The study identified specific environmental stressors that exacerbate the impact of staffing shortages on patient safety.

Conclusions:

• Decreased RN staffing, increased workload, and unstable nursing unit environments are critical risk factors for adverse patient outcomes, including falls and medication errors.
• Interventions aimed at improving nurse staffing levels and stabilizing unit environments are crucial for enhancing patient safety on medical/surgical units.
• Healthcare organizations must address these systemic issues to mitigate risks and improve the quality of care.
