Are 12-Hour Nursing Shifts Putting Patients and Nurses at Risk?

"A new study reveals the hidden dangers of long shifts and the importance of balanced nurse scheduling for quality care."


In the demanding world of healthcare, hospitals are constantly seeking ways to improve efficiency and manage costs. One common strategy has been the adoption of 12-hour shifts for nursing staff. The intention is clear: streamline operations, reduce shift overlaps, and provide consistent patient care. However, emerging research suggests that this approach might be a double-edged sword, potentially compromising both patient safety and the well-being of nurses.

A recent study published in the Journal of Nursing Management sheds light on the potential downsides of long nursing shifts. Researchers investigated the correlation between 12-hour shifts and sickness absence among nurses and healthcare assistants. The findings raise concerns about the sustainability and overall impact of these extended work periods.

As healthcare systems grapple with staffing shortages and financial pressures, it's crucial to examine the less obvious consequences of decisions made at the administrative level. Let's delve into this research and explore the critical balance between efficiency and quality in nursing care.

The Hidden Costs of 12-Hour Shifts: What the Research Reveals

The study, led by Chiara Dall'Ora and colleagues, analyzed data from over 600,000 shifts worked by nearly 2,000 nurses and healthcare assistants across 32 general inpatient wards in an acute hospital in England. The research team examined the relationship between shift patterns and subsequent sickness absence, categorizing absences as short-term (less than 7 days) or long-term (7 days or more).

The results indicated a significant association between working long shifts and increased sickness absence. Specifically, when more than 75% of shifts worked in the past 7 days were 12 hours in length, the odds of both short-term and long-term sickness episodes increased. Here's a breakdown of the key findings:
  • Increased Odds of Sickness: Nurses working predominantly 12-hour shifts had a higher likelihood of both short-term and long-term sickness absences.
  • Impact on Absence Length: The study distinguished between short-term and long-term absences, suggesting different underlying factors related to health and well-being.
  • Objective Data: Unlike previous studies relying on self-reported data, this research used routinely collected data, providing a more objective assessment of sickness absence.
These findings suggest that while 12-hour shifts might seem like an efficient solution, they could inadvertently lead to increased staff absences, potentially offsetting any cost savings. The implications for nursing management are significant, highlighting the need to carefully consider the impact of shift scheduling on staff health and productivity.

Re-evaluating Shift Patterns: Balancing Efficiency and Nurse Well-being

The study underscores the importance of creating work environments that support the health and well-being of nurses. While 12-hour shifts may offer some advantages in terms of scheduling flexibility and reduced shift overlaps, healthcare administrators must carefully weigh these benefits against the potential for increased sickness absence and decreased productivity. Implementing strategies to mitigate the negative impacts of long shifts, such as ensuring adequate rest breaks, managing workload, and promoting a supportive work culture, could help to create a healthier and more sustainable nursing workforce. Ultimately, the goal is to find a balance that promotes both efficiency and the delivery of high-quality patient care.
