In a delicate environment such as the emergency department, risk assessment is not merely a preventive measure: it is a strategic pillar for ensuring safety, compliance, and staff protection. Through advanced techniques, innovative technologies, and strict legal oversight, Argo supports healthcare facilities in creating safer environments.

When Tension Escalates: Recognizing Risk Signals

Violence against healthcare personnel often arises from factors such as prolonged waiting times, emotional stress, and overcrowding. Subtle yet unmistakable signs—such as a raised voice, whispered or explicit threats, nervous movements, tense stares, rigid postures, or invasion of personal space—are indicators that, if recognized in time, allow immediate de-escalation countermeasures to be initiated.

Numbers That Give Pause for Thought

With Law no. 113 of 14 August 2020, the National Observatory on the Safety of Healthcare and Social-Healthcare Professionals (ONSEPS) was established, with the aim of monitoring, studying, and promoting initiatives to ensure the safety of professionals.

By 31 March of each year, ONSEPS must submit to the government a report on the activities carried out during the previous months. One of these activities concerns the collection of regional data relating to the scale and frequency of violent incidents committed against healthcare and social-healthcare professionals. ONSEPS cooperates with the National Observatory of Best Practices, the General Directorates for Health Planning and Information Systems of the Ministry, and the National Agency for Regional Healthcare Services in order to collect data on violent incidents. These data derive from voluntary reporting by workers through the completion of a reporting form.

At the conclusion of the research, it emerged that during 2024:

• Over 18,000 assaults were recorded, involving approximately 22,000 workers, marking a +15% increase compared to 2023.
• Women represent over 60% of victims, with the most affected age group being 30–49 years.
• Nurses (55%) are more affected than physicians (17.3%) and social healthcare workers (9.5%).
• The perpetrators are mostly patients (67%), followed by caregivers (29%) and strangers (4%), with verbal aggression (70%) prevailing over physical aggression (24%).

These figures call for structured and proactive solutions.

Risk Factors in the Emergency Healthcare Context

International literature provides an in-depth analysis of the main risk factors related to violence against healthcare professionals. Specifically, it has been observed that young age and limited experience expose healthcare staff to greater risks due to a reduced ability to interpret warning signs. Moreover, triage is confirmed as the most dangerous activity, as it represents the first point of contact with patients. During triage, it is necessary to communicate with patients and assist them in the waiting room, as well as manage reactions to delays—activities that increase the risk of violence.

Patients presenting alcohol intoxication or substance abuse are at high risk of potential violence, increasing the risk for nurses of experiencing violence by six times. Patients with mental health issues also represent a high-risk group: long waiting times lead to overcrowding and high noise levels, creating an environment that is particularly hostile to managing this type of patient.

Finally, dissatisfaction with waiting times has been identified as a crucial trigger for violence, especially because patients often continue to wait even after being admitted to the specific department, for example for test results or specialist consultations.

Further research also provides a comprehensive overview of recent studies regarding the correlation between emergency department overcrowding and violence against nurses. The literature suggests that every individual has a psychological threshold beyond which waiting is no longer tolerated and that, once exceeded, may generate feelings of frustration and anger, potentially leading to violent behavior. Dissatisfaction and the perception of poor quality of care are additional factors that can increase patient anxiety and thus create a negative emergency department experience. These two factors are particularly emphasized in overcrowded situations, during which waiting times increase and patients’ sense of injustice grows.

Conversely, when patients perceive an atmosphere of order, clarity, and control, understanding increases and the likelihood of violence decreases.

Risk Assessment in Emergency Healthcare: Methodology and Prevention

Risk assessment applied to emergency departments is a methodical and multidimensional process aimed at identifying, analyzing, and evaluating threats that may compromise the safety of healthcare personnel, patients, and infrastructure. Unlike other contexts, the emergency hospital environment presents unique characteristics: a high influx of people in extreme emotional states, unpredictability of workload, the coexistence of patients and family members in limited spaces, and the need to ensure uninterrupted operational continuity.

Risk analysis must necessarily begin with a physical and functional mapping of the emergency department area, including: access points, triage areas, waiting rooms, transit corridors, short-stay rooms, drug and device storage areas, as well as any routes for patient transport. Each area must be evaluated based on parameters such as level of exposure, ease of intrusion, visibility, and the possibility of timely intervention.

In parallel, a procedural assessment is carried out: how patient flows are managed, how communication with family members is handled, how overcrowding situations are addressed, and what the average waiting times are in different time slots. These data, cross-referenced with the times and days when statistically more episodes of tension occur, as well as with environmental factors such as crowding, physical layout of spaces, and perception of incorrect triage prioritization, allow for the construction of a structured risk matrix combining probability and impact.

The threat modeling framework includes scenarios such as verbal aggression, physical threats, use of improvised weapons, attempts to access restricted areas, damage to critical infrastructure (electrical panels, diagnostic equipment), and theft of drugs or medical devices. Each scenario is weighted in terms of existing vulnerabilities (lack of physical safeguards, long response times, staff not trained in de-escalation) and countermeasures already implemented.

The value of risk assessment lies in the transition from a reactive to a proactive approach: the goal is not only to respond to incidents, but to reduce the likelihood of their occurrence by integrating training, architecture, technologies, and policies into a single strategic framework.

Advanced Security Technologies: Access Control, IoT, Predictive AI

The technological infrastructure of a modern emergency department can become a security multiplier if properly designed and managed. This is not merely about installing cameras or access control systems, but about building an integrated ecosystem of detection, prevention, and response. An essential countermeasure is represented by access control systems: RFID badges, electronic locks, biometric systems, or facial recognition can limit access to highly critical areas (emergency rooms, pediatric areas, drug storage), preventing intrusions. Some systems integrate access control with peak-time management, allowing the rigidity of barriers to be modulated based on operational pressure.

Wearable alert devices worn by staff allow a silent signal to be sent in case of threat, geolocating the operator in distress. These tools, if connected to an internal security control room, can be integrated with local law enforcement for direct intervention. IoT sensor technology represents an additional level of protection: environmental sensors to detect movement in restricted areas, people counters to prevent overcrowding, microphones to identify abnormal noise peaks associated with conflict situations. Finally, AI-based predictivity opens even more proactive scenarios: by analyzing patient flows, weather conditions, local events, and historical incident data, it is possible to estimate when the level of risk will increase and prepare a reinforcement of security measures. This enables more efficient use of resources and a targeted response.

How to Act During an Aggression: Operational Protocols and De-escalation

When a threat materializes, the priority is to contain the immediate risk and protect the people involved. At this stage, the risk assessment activity must have produced standard operating procedures that are clear and applicable within short timeframes. In 2019, the Joint Commission published a guide presenting several de-escalation and intervention models for managing aggressive patients. By definition, de-escalation is a set of strategies, techniques, and methods that can be used to reduce patient aggression and agitation.

1. Immediate activation of an internal alarm code, alerting all personnel involved in managing security emergencies. The response may include securing areas by closing access points, blocking elevators, and diverting the flow of people toward safe zones. Operators must be trained in de-escalation techniques.
2. Use of de-escalation techniques based on models such as Dix & Page or Turnbull et al., with a flexible, clear, and reassuring approach. The Dix and Page and Turnbull et al. models focus on three interdependent components: assessment, communication, and tactics. The core of these models is constant monitoring of the aggressor through requests for feedback. Furthermore, the authors emphasize the importance of flexibility on the part of the de-escalator, who must be able to tailor the approach, as what may calm one person may inflame another.
3. In situations of imminent physical threat, the protocol provides for the immediate intervention of internal security and, if necessary, activation of a direct connection with law enforcement. Spaces must be designed to facilitate intervention.
4. Post-event debriefing: collection of testimonies, analysis of response times, evaluation of countermeasures, and updating of the security plan. At the same time, involved staff must have immediate access to post-event psychological support to mitigate stress and prevent long-term consequences such as burnout or post-traumatic stress disorder.

The Future of Emergency Department Security with Argo’s EWS

Security in emergency departments is evolving toward an integrated, predictive, and people-centered model, in which healthcare professionals, risk management experts, healthcare cybersecurity specialists, technologists, and institutional decision-makers cooperate. Reacting is no longer sufficient: it is necessary to anticipate risk, transforming security into a structural element of healthcare governance.

One of the main challenges will be precisely this shift—from a reactive approach to a proactive strategy based on accurate risk analysis, integrated from the design phase of departments, into staff training, and into daily operational planning. In this context, innovation plays a crucial role: predictive systems based on artificial intelligence, smart infrastructures, wearable technologies, and advanced sensors make it possible to promptly intercept escalation signals and activate immediate containment measures. However, technology alone is not enough: investing in human skills is essential. Assertive communication, stress management, and effective de-escalation techniques must become an integral part of every healthcare professional’s operational toolkit.

From this perspective, Argo has developed EWS – Early Violence Warning, a proprietary early threat detection system. Through the integration of artificial intelligence, environmental sensors, and behavioral analysis, EWS is able to identify risk signals at an early stage and activate targeted de-escalation countermeasures. By processing real-time data—including triage data, environmental indicators, and historical information on violent incidents—EWS enables the transformation of security management from reactive to structural, improving the protection of healthcare personnel and enhancing the overall quality of the care environment.

With EWS, Argo confirms its commitment to safeguarding hospital security and to disseminating advanced technological solutions, always in compliance with regulations and inspired by the highest standards of integrity and confidentiality.
