Nursing shortages and patient outcomes

Area of Science:

• Healthcare Management
• Nursing Economics
• Patient Safety

Background:

• Nurse shortages are a growing concern in healthcare systems globally.
• The impact of nursing staff levels on patient outcomes requires further investigation.

Purpose of the Study:

• To quantify the effect of nurse shortages on inpatient mortality.
• To analyze the differential impact of shortages based on nurse qualifications and patient severity.

Main Methods:

• Utilized novel high-frequency data to analyze the relationship between nursing staff absence and patient mortality.
• Differentiated analysis based on nurse qualification levels (degree-qualified vs. nursing assistants).

Main Results:

• Shortages of degree-qualified nurses increase inpatient mortality odds by approximately 10%.
• No significant mortality impact was found from shortages of nursing assistants.
• Increased firm-specific experience for qualified nurses correlates with reduced mortality.
• Adverse effects are more pronounced in patients with lower clinical severity, especially sepsis.

Conclusions:

• The qualification and experience of nursing staff are critical determinants of patient survival.
• Targeted staffing of degree-qualified nurses is essential for mitigating mortality risks.
• Hospital policies should focus on retaining experienced, qualified nurses to improve patient safety.
