CPI training is a workplace safety program developed by the Crisis Prevention Institute that teaches healthcare workers how to de-escalate aggressive or agitated behavior and, when absolutely necessary, physically intervene to protect patients and staff. The program’s full name is Nonviolent Crisis Intervention, and it’s one of the most widely used crisis prevention curricula in hospitals, psychiatric facilities, and emergency departments across the United States.
The core idea is straightforward: give staff a shared framework for recognizing when a situation is escalating and responding in a way that keeps everyone safe, with physical restraint treated as a last resort rather than a first response.
What the Training Actually Covers
CPI training is built around a four-stage model of how crises develop. Each stage describes what the person in crisis is experiencing and what the staff member should do in response.
- Anxiety. The person’s behavior changes noticeably. They may seem restless, irritable, or withdrawn. Staff are taught to respond with empathy and a calm tone to address the anxiety before it builds.
- Defensive behavior. If anxiety isn’t resolved, the person starts to feel challenged or threatened. They might pace, raise their voice, or refuse to cooperate. The trained response here is to give clear, simple directions that help the person feel safe and regain composure.
- Risk behavior. At this stage, the person’s actions could harm themselves or others. Staff practice safety interventions designed to maximize protection while minimizing harm.
- Tension reduction. After the peak of a crisis, the body depletes its physical and emotional energy. This is the window for reconnecting with the person, rebuilding trust, and debriefing both the individual and the staff involved.
The model gives every trained staff member a common vocabulary. When a nurse says a patient is at the “defensive behavior” stage, everyone on the team knows what that means and what the appropriate response looks like.
Three Levels of Training
Not every healthcare worker needs the same depth of training. CPI structures its program into three tiers based on the level of risk a role involves.
Verbal Intervention focuses entirely on communication. Staff learn a de-escalation framework and proactive verbal strategies for calming disruptive behavior. This level suits roles with lower physical risk, like administrative staff or outpatient clinicians.
Nonviolent Crisis Intervention adds safe disengagement and physical intervention skills on top of the verbal foundation. This is the standard level for most bedside healthcare workers, including nurses, patient care technicians, and support services staff.
NCI With Advanced Physical Skills is designed for higher-risk roles where staff regularly encounter physically aggressive behavior. It includes everything from the previous two tiers plus advanced techniques for managing dangerous situations. Emergency department and inpatient psychiatric staff often train at this level.
Who Needs It and How Often
Hospitals typically require CPI training across a broad range of roles. At UCSF Health, for example, the program covers doctors, nurses, patient care assistants, and support services staff. The specific departments that mandate it vary by institution, but emergency departments, behavioral health units, and inpatient floors with high patient acuity almost always require it.
Certified Instructors, the in-house staff who teach the program to their colleagues, must attend renewal training through CPI every two years to maintain their certification. CPI recommends that general staff receive refresher training every 6 to 12 months, though the exact frequency depends on hospital policy. This ongoing cycle matters because skills like verbal de-escalation and physical safety techniques degrade without practice.
Why Hospitals Invest in It
Workplace violence in healthcare is a serious and growing problem. Nurses, emergency physicians, and psychiatric staff face assault rates far higher than workers in most other industries. CPI training gives organizations a structured way to reduce those incidents.
The results can be significant when leadership commits to the program. At CHRISTUS Southern New Mexico, staff injuries from violent incidents dropped from 20 in 2022 to 12 in 2023 to just 7 in 2024, a 65% reduction over two years. The hospital credited the improvement to a combination of CPI training and genuine leadership support for the program’s principles.
The training also helps hospitals meet federal regulatory requirements. CMS (the agency that oversees Medicare and Medicaid) requires hospitals to train staff in specific competencies before they can be involved in any restraint or seclusion situation. Those competencies include identifying behavioral triggers, using nonphysical intervention skills, choosing the least restrictive intervention possible, recognizing signs of physical distress like positional asphyxia during restraint, and monitoring a restrained patient’s respiratory and circulatory status. CPI’s curriculum maps directly onto these requirements, which is a major reason hospitals adopt it.
What a Training Session Looks Like
CPI’s teaching approach is hands-on rather than lecture-based. The program uses a learning theory called constructivism, which means participants build new skills on top of their existing experience rather than memorizing definitions. Sessions include case studies drawn from real-world scenarios, interactive group discussions, and physical practice of disengagement techniques for the tiers that include them.
The most recent version of the curriculum, the 3rd Edition, made deliberate changes to strip out academic jargon. Previous editions used terms like “haptics” and “kinesics” to describe types of nonverbal communication. The updated program dropped those terms entirely, focusing instead on whether staff can actually apply the concepts. The 3rd Edition also added a new module on the brain-body connection during crisis, drawing on current research in trauma and neuroscience to help staff understand why people behave the way they do when they feel threatened.
Initial training typically takes one to two days depending on the tier. Refresher sessions are shorter, designed to reinforce key skills and correct any drift from the original techniques. Staff are expected to demonstrate competency, not just attend, and hospitals document successful completion in personnel records as required by CMS.
The Emphasis on Restraint as a Last Resort
One of the defining features of CPI’s philosophy is that physical restraint should only happen during a behavioral emergency when someone is at immediate risk of harm. The entire program structure reinforces this: staff spend the majority of training time on prevention and verbal strategies. Physical techniques come last in the curriculum and are framed explicitly as what you do when everything else has failed.
This isn’t just philosophy. Federal regulations require hospitals to document and justify every use of restraint or seclusion, and accrediting bodies like The Joint Commission actively push for restraint reduction. Training programs that teach staff to intervene earlier in the crisis cycle, during the anxiety or defensive behavior stages, directly reduce the number of situations that ever reach the point where physical intervention becomes necessary.
