Organizational and Safety Culture Determinants of Nurses’ Psychosocial Well-being: A Hierarchical Multiple Regression Study in Greek Tertiary Hospitals
This cross-sectional study of Greek tertiary hospital nurses reveals that organizational factors like staffing levels, workflow interruptions, and electronic medication systems, alongside patient safety culture dimensions, significantly shape nurses' psychosocial well-being, highlighting the need for adequate staffing and supportive leadership to mitigate risks and sustain high-quality care.

In the high-stakes environment of a hospital, the well-being of the nursing staff is not merely a matter of personal comfort; it is a fundamental pillar of patient safety. When nurses face overwhelming workloads, constant interruptions, or a lack of support, their ability to make clear clinical decisions can falter, potentially leading to medication errors or missed care. Researchers have long understood that the psychological atmosphere of a workplace—often called the "safety culture"—plays a critical role in how staff perform. This culture includes how teams communicate, how leaders respond to mistakes, and whether staff feel safe reporting problems without fear of punishment. However, the specific ways these organizational factors mix with daily tasks, such as administering medicine or using electronic record systems, to shape a nurse's mental health have remained somewhat unclear, particularly within the Greek healthcare system.
To untangle this complex web, a team of researchers from Greek universities conducted a large-scale survey involving 514 nurses across four major tertiary hospitals. These are large medical centers that handle the most complex cases, often serving as the backbone of regional healthcare. The study took place over more than a year, from late 2022 through the end of 2023. The researchers asked nurses to fill out detailed questionnaires about their daily experiences. They measured ten specific aspects of their psychological well-being, ranging from how fast they felt they had to work and how emotionally drained they felt, to their job satisfaction and sense of security in their roles. They also gathered data on the hospital environment, including whether the unit used electronic systems to manage medicines, how often nurses were interrupted while giving medication, and how strong the team's safety culture was. By using a statistical method that allowed them to look at all these factors at once, the team could see which elements of the work environment were most strongly linked to how nurses felt.
The results revealed a landscape of connections that were often surprising and sometimes contradictory. For instance, the presence of an electronic system for managing medications was a double-edged sword. On one hand, nurses working in units with these systems reported feeling a slower, more manageable work pace and less burnout, likely because the technology helped organize information and reduce confusion. On the other hand, these same nurses reported higher levels of role conflict—feeling torn between different expectations—and a greater sense of job insecurity. This suggests that while the technology might streamline some tasks, its introduction can also create new anxieties or blur the lines of responsibility if not accompanied by clear training and support.
Interruptions emerged as a significant disruptor of well-being. Nurses who reported being frequently distracted or interrupted while administering medication described higher emotional demands, more conflict between their work and personal lives, and lower job satisfaction. It appears that the constant breaking of concentration required to manage these interruptions takes a heavy toll on a nurse's mental resources. Conversely, the application of critical thinking before carrying out medical orders was linked to lower emotional demands and higher job satisfaction, highlighting the value of nurses feeling empowered to pause and verify their actions.
The study also shed light on the role of education and leadership. Nurses who participated in frequent continuing education programs reported higher work paces and emotional demands, which the researchers suggest might indicate that these programs are often added to already full schedules without providing the necessary time or staffing to absorb them. However, these same programs were linked to lower burnout, suggesting that professional growth is a powerful buffer against exhaustion, provided it is supported by the organization. Leadership and safety culture showed a similarly nuanced picture. Strong teamwork and open communication were generally positive, yet in some statistical models, they appeared alongside higher levels of conflict or lower leadership satisfaction. The researchers caution that this does not mean teamwork causes conflict; rather, it may be that in units where problems are already visible and being addressed, staff are more likely to report both the existence of conflict and the efforts to solve it.
Perhaps the most striking finding concerned the perception of staffing. When nurses felt that their units were well-staffed, it was associated with lower burnout and better safety outcomes. Yet, in the complex statistical models, higher ratings of staffing adequacy were sometimes linked to lower job satisfaction and engagement. The authors explain this not as evidence that having more staff makes nurses unhappy, but rather as a reflection of how different factors overlap. It is possible that in units where staffing is perceived as adequate, the expectations for performance are also higher, or that the measure of "adequate staffing" captures a different reality than the simple count of nurses on the floor. The study explicitly notes that these associations do not prove that good conditions cause bad feelings; instead, they highlight how deeply intertwined these variables are.
Ultimately, the research paints a picture of a profession where well-being is shaped by a delicate balance of resources, technology, and culture. The findings suggest that protecting nurses' mental health requires more than just hiring more staff or installing new computers. It demands a holistic approach where technological tools are introduced with clear guidance, where education is integrated into the workflow rather than added on top of it, and where safety culture is built on trust and non-punitive responses to errors. The study concludes that when nurses work in conditions that support their psychological safety, the entire hospital system becomes safer for patients. The message is clear: the quality of care a patient receives is inextricably linked to the quality of the environment in which the nurse works.
