Medical trauma

More than half of ICU survivors have new or worsening problems with their body, thinking or mental health afterwards. This is called post-intensive care syndrome, or PICS.

Things can happen very fast in an emergency, with little time to understand or agree to what is happening. Afterwards, people may feel shocked, confused or as if they lost control of their own body.

A serious diagnosis can be traumatic in itself. Studies of people with cancer show that some develop PTSD-like stress symptoms, especially after treatment or if cancer comes back.

Birth can be one of the most intense medical experiences a person goes through. Birth partners who were there can be affected too.

Medical trauma doesn’t always come from one big event. It can also build from many painful or frightening experiences over time.

Feeling powerless or ignored during care can be just as hard as the illness itself. Afterwards, many people find it harder to trust care teams or health systems.

Physical problems are the most common part of PICS, affecting about 46% of survivors in a 2025 review.

The NHS lists weakness, stiffness, fatigue, loss of appetite, weight loss and sleep problems after intensive care. Some people need rehabilitation.

About 1 in 3 ICU survivors have problems with thinking or memory afterwards.

These problems can be frustrating and frightening. Tell your clinical provider so they can check what’s happening and suggest support.

About 1 in 3 ICU survivors have mental health effects afterwards. The NHS lists depression, anxiety and PTSD among possible lasting effects of intensive care.

Some people also feel guilty for causing their family so much worry.

ICUsteps explains that vivid dreams in intensive care can feel very real, and some people dream of being trapped or hurt. These may be linked to the tubes and equipment used in the ICU.

The fear from these dreams can last for weeks after leaving the ICU.

Hallucinations and nightmares are common in intensive care and are often called ICU delirium. Some people feel suspicious or frightened of staff while confused. This usually fades over time.

It is normal not to remember everything. Flashbacks can happen too, and sounds, smells or sights, like a beeping machine, can set them off.

Some hospitals and families keep a diary while a person is in intensive care. Many survivors find reading it helpful when they feel ready.

In a trial across six European countries, survivors who got a diary of their ICU stay developed new PTSD less often (5%) than those who didn’t (13%).

At follow-up clinics, some people can see the ICU and staff again and ask questions about their care. Bringing someone you trust can make it less frightening.

A review of 24 studies found that about 12% of people who had a heart attack or similar heart event had significant PTSD symptoms afterwards.

Some people become very watchful of every heartbeat or twinge, or afraid to exercise. Talk with your care team about cardiac rehab and about how you’re feeling.

Waking up in pain, with tubes, or to news that things didn’t go as planned can be a shock. Asking your team to explain what happened can help the memory make more sense.

Changes in how your body looks or works are a common secondary stress after medical trauma. It can take time to feel at home in your body again.

Linked to more stress symptoms (NCI)

• A past history of trauma
• Cancer coming back
• High distress around the time of diagnosis
• Less support from others
• Ongoing pain or physical symptoms

People who feel more supported tend to have fewer stress symptoms. Clear, timely health information and good relationships with care staff may also protect.

Many people feel anxious in the days before a scan or check-up. Planning something comforting for waiting days, and someone to call when results come, can help.

ISTSS lists missed visits and not following through on care as signs of medical trauma.

Avoiding care is understandable, but it can put your health at risk. Telling your care team that appointments are hard for you can help them change how they work with you.

Strong distress or agitation during visits can be a sign that past care was traumatic.

Some people go along with everything and just want exams or procedures to be over quickly. ISTSS notes this can also be a sign of medical trauma.

Being on high alert about your body, your care team or the health system is another sign ISTSS describes.

Some people freeze, stop talking, or find it hard to make decisions or understand what they’re told. Some turn to alcohol or substances to cope.

In one study of people treated for cancer as children, about 1 in 5 had PTSD at some point after treatment ended. Feeling unsure about their illness and future was linked to more stress symptoms.

What helps children (D-E-F)

• Distress: ask about pain, fears and worries, and ease them
• Emotional support: think about who and what the child needs right now
• Family: remember the family’s stress and strengths

Pediatric medical trauma includes the reactions of parents, not only children.

Parents often hold it together during a crisis and fall apart later. That is a normal reaction to prolonged fear.

Experts agreed that post-intensive care syndrome can affect family members as well as the patient. This is sometimes called PICS-F.

Sitting by a bed for days, making hard decisions and fearing the worst can leave lasting anxiety, low mood or traumatic stress.

PTSD after intensive care is treatable. Therapies such as EMDR aim to reduce trauma symptoms.

ICUsteps runs an online community and local support groups for intensive care survivors and families. Many hospitals and condition-specific charities run similar groups.

Telling a new care team what was hard before lets them adjust. Health workers are encouraged to explain what’s coming, offer choices, and repair quickly when something goes wrong.
