Patient safety in healthcare is essential, involving a variety of factors, of which the human factor is particularly significant. Healthcare professionals—physicians, nurses, or other staff—operate in complex environments that demand rapid and precise decisions.

However, the inevitability of human fallibility can lead to errors, even among the most experienced. Recognizing the importance of human factors is therefore vital to improving the quality and safety of care, reducing the risk of errors with severe impacts on patients.

Training and awareness regarding human factors are key. By integrating it into their practice, healthcare personnel can develop strategies to anticipate errors and strengthen risk management, establishing an environment where errors serve as learning opportunities. This article highlights the importance of human factors in healthcare, recognizes the sources of human errors, and suggests approaches to minimize them.

Understanding the importance of the human factor in healthcare

Medical errors: dimensions and impact

Medical errors represent a significant public health concern, with substantial repercussions for patients, healthcare professionals, and the healthcare system as a whole. Research indicates that medical errors are among the leading causes of death in the United States, responsible for approximately 400,000 preventable harms annually in hospitalized patients, and leading to over 200,000 deaths each year due to preventable errors.

They can include different types, such as diagnostic errors, medication errors, surgical errors, equipment failures, patient falls, hospital-acquired infections, and communication failures. These errors have a considerable impact on the health and well-being of patients, but also significantly affect the morale and mental health of the healthcare professionals involved. Indeed, the psychological consequences for professionals can be severe, ranging from anger to depression, and can include feelings of guilt, inadequacy, and even suicidal thoughts, particularly in the presence of a risk of litigation.

The contribution of non-technical skills to patient safety

Beyond technical skills, non-technical skills play a vital role in the safety and quality of care provided. Including communication, teamwork, situational awareness, and stress management, these skills are essential for preventing errors and promoting better patient outcomes.

In a crisis situation, the combination of technical and non-technical skills is essential to guarantee the quality and safety of care. Non-technical skills enable healthcare professionals to optimize their interaction with the environment, manage task interruptions, communicate effectively with colleagues, and make informed decisions in a context of pressure.

Human factors engineering, which considers the interactions between individuals, technologies, and the work environment, highlights the need to design systems and processes that take into account human capabilities and limitations. This includes the standardization of procedures, the use of checklists, and the reduction of dependence on individual vigilance, all aimed at minimizing the risk of errors and increasing patient safety.

Identify the main sources of human error in care.

Cognitive and psychological limitations

Healthcare professionals, despite their expertise and training, are subject to cognitive and psychological limitations that can influence their decision-making and performance. Cognitive biases, such as premature closure, confirmation bias, and sunk costs, are frequent examples of these limitations.

For example, a physician may accept a diagnosis without considering all possible differential diagnoses, or only seek information that confirms their initial diagnosis, rather than considering other possibilities.

In addition, the tunnel effect, or attentional tunneling, can occur when a professional's attention is too focused on one objective, preventing them from perceiving other important warning signals. This fixation of attention can be reinforced by pressure from the result, stress, alarms, and noise, and can occur at any time, even among experienced professionals.

Communication and collaboration failures

Failures in communication and collaboration between members of healthcare teams are another major source of human error. Studies have shown that over 70% of adverse events in healthcare are caused by communication failures.

These failures can include problems with information transmission, misunderstandings, and a lack of clarity in the roles and responsibilities of team members. Effective and respectful communication between physicians, nurses, and other healthcare professionals is essential to prevent these errors and ensure patient safety.

The effects of stress and fatigue on professional performance

Stress and fatigue are significant factors that can affect the performance of healthcare professionals. Excessive workload, extended work hours, and crisis situations can all contribute to physical and mental exhaustion.

These conditions can impair concentration, decision-making, and the ability to manage complex situations, thereby increasing the risk of errors. In addition, fatigue and stress can exacerbate cognitive biases and reduce situational awareness, which can have serious consequences for patient safety.

Strategies for minimizing human error in healthcare environments

Improving the training of medical staff on non-technical skills

Training medical staff on non-technical skills represents a crucial approach to reducing human errors in the healthcare sector. These skills, including communication, teamwork, leadership, and decision-making under pressure, play a determining role in ensuring the safety and quality of care provided. Training through clinical simulation is particularly beneficial, offering an ideal setting for refining these essential skills.

At the heart of multidisciplinary clinical simulation scenarios, teams can focus on improving these skills in realistic contexts, reinforcing their ability to manage critical events appropriately. In addition, the integration of continuing education programs focused on interpersonal skills, situation awareness, and stress management can play a significant role in minimizing errors. It is imperative that these programs are frequent and open to all healthcare stakeholders, ensuring continuous updating of knowledge on the latest clinical guidelines and best practices.

Development of a safety culture in healthcare facilities

Establishing a safety culture within healthcare facilities is essential for minimizing human error. This culture encompasses a set of common practices and perceptions within the organization, oriented towards patient safety.

It promotes a collaborative and non-punitive approach to errors, thus encouraging a fair culture where professionals are encouraged to report incidents without fear of repercussions. Approaches such as evaluating the safety culture and creating programs to improve its aspects can help structures detect and correct organizational and procedural flaws.

This safety culture also promotes transparency, accountability, and commitment at all levels of the organization, from caregivers to leaders, thereby facilitating the implementation of necessary improvements and adopting a proactive approach to patient safety.

Using technology to support clinical decision-making

The adoption of advanced technologies can play a decisive role in supporting clinical decision-making and reducing human error. The application of evidence-based practices, supported by rigorous clinical research, can be facilitated through computerized clinical decision support systems. These systems help healthcare professionals adopt standardized treatment protocols, monitor medication prescriptions, and identify early warning signs of adverse events.

In addition, technology improves communication and coordination among members of the care team. Care management tools and health information systems optimize information sharing and mitigate communication errors. Robust cybersecurity is also essential for protecting patient data and preventing cyber risks that could compromise the safety of care.

The importance of learning from mistakes: creating a blame-free environment

Encourage the reporting of incidents and near misses

Establishing a blame-free environment within healthcare facilities is essential to encourage the reporting of incidents and near-incidents. When healthcare professionals feel safe reporting adverse events without fear of reprimand or judgment, they are more likely to share their experiences, thereby facilitating rigorous evaluation and continuous improvement of procedures. This strategy promotes a culture of transparency and collective responsibility, where mistakes are seen as learning opportunities rather than individual failures.

Anonymous or confidential reporting mechanisms can play a significant role in increasing the volume of incident reports, allowing for more precise detection of systemic flaws and risks. This preventive approach is essential for implementing corrective measures before significant errors emerge, thereby contributing to enhancing the safety and quality of care provided.

Analysis of adverse events: lessons learned

The meticulous dissection of adverse events is an essential pillar in the learning process from errors, as well as in the optimization of care methods. This investigation, often carried out using structured tools such as the fault tree or the ALARM method, is vital to clarify the deep origins of malfunctions and to reveal both the immediate and subsequent failures of the delivery network.

Through a scrupulous and objective examination of incidents, healthcare teams are able to extract fundamental lessons that will guide the necessary adjustments to avoid the repetition of these same errors.

These retrospective evaluations must be carried out in consultation, involving each stakeholder in the event, to ensure a comprehensive understanding of the circumstances and factors contributing to the error. It is imperative that the conclusions of these investigations be communicated within the team and the institution, in order to foster a culture of continuous learning and patient safety.

Promoting a systemic approach to understanding errors

To truly grasp and leverage errors, it is critical to adopt a systemic view. This involves perceiving errors not as isolated failures, but as symptoms of shortcomings within the healthcare system.

This approach encompasses the organizational, environmental, and human elements that fuel errors, such as work protocols, operational load, available resources, and organizational culture.

Using analytical tools such as cause-and-effect diagrams (Ishikawa diagrams) or the 5M/6M (Management, Milieu, Manpower, Material, Method), teams are able to identify and examine the multiple facets of the system contributing to the error. This systemic approach is essential for establishing comprehensive and sustainable corrective solutions, aimed at improving the safety and quality of care in a holistic manner.

The future of human factors management in healthcare

The application of behavioral science and ergonomics.

The future approach to human factors in healthcare will be significantly shaped by the rigorous application of behavioral science and ergonomics. These fields of study are essential for analyzing and optimizing the relationship between healthcare professionals, patients, and their work environment. Ergonomics, in particular, is essential for designing systems and procedures that take human characteristics into account, thereby reducing errors while enhancing patient safety.

Entities such as the Human Factors in Healthcare Association are dedicated to unifying simulation-based and human factors-focused educational programs to improve the quality and safety of care provided. This approach promotes research on human and organizational dynamics while supporting educational initiatives that apply the principles of ergonomics and behavioral sciences.

Integration of artificial intelligence tools to predict and prevent errors

The adoption of artificial intelligence (AI) tools is a major focus in the future development of human factors management in healthcare. AI has the capacity to analyze large quantities of data to identify anomalies, propose alternative diagnoses, and verify that appropriate examinations are requested. This technology has the potential to drastically reduce diagnostic and therapeutic errors, while improving patient care pathways.

AI algorithms also play an important role in predictive medicine, examining genetic data, lifestyles, and medical histories to identify at-risk individuals even before symptoms emerge. This strategy makes it possible to act upstream with targeted interventions and tailored preventions, thereby reducing the incidence of severe pathologies.

Leadership in healthcare safety: a key role for managers

Leadership in healthcare safety stands as a pillar in the future vision of human factors management. It is imperative that managers and leaders of healthcare infrastructures cultivate a safety culture in which errors are perceived as opportunities for improvement rather than individual failures. They are required to foster transparency, accountability, and active participation at all levels of the organization to propel the safety and quality of care.

Effective management also requires the development of policies and procedures that encourage team collaboration, effective communication and the use of AI tools to support clinical decisions. Managers must also invest in the ongoing professional development of healthcare staff in soft skills, and in the systematic review of incidents to identify and rectify systemic problems.
