A TBI is caused by a bump, blow or jolt to the head or a penetrating head injury that disrupts the normal function of the brain. Not all blows or jolts to the head result in a TBI. The severity of a TBI may range from “mild,” i.e., a brief change in mental status or consciousness to “severe,” i.e., an extended period of unconsciousness or amnesia after the injury. The majority of TBIs that occur each year are concussions or other forms of mild TBI.2

Clinical Diagnosis and Management

Clinicians play a key role in helping to identify, diagnose and manage traumatic brain injuries (TBIs). They can also help improve patient outcomes when a TBI is suspected or diagnosed by implementing early management and appropriate referral.

Prevention

What Can I do to Help Prevent Traumatic Brain Injury?

There are many ways to reduce the chances of sustaining a traumatic brain injury, including:

• Buckling your child in the car using a child safety seat, booster seat, or seat belt (according to the child's height, weight, and age).
• Wearing a seat belt every time you drive or ride in a motor vehicle.
• Never driving while under the influence of alcohol or drugs.
• Wearing a helmet and making sure your children wear helmets when:
• Riding a bike, motorcycle, snowmobile, scooter, or all-terrain vehicle;
• Playing a contact sport, such as football, ice hockey, or boxing;
• Using in-line skates or riding a skateboard;
• Batting and running bases in baseball or softball;
• Riding a horse; or
• Skiing or snowboarding.
• Making living areas safer for seniors, by:
• Removing tripping hazards such as throw rugs and clutter in walkways;
• Using nonslip mats in the bathtub and on shower floors; Installing grab bars next to the toilet and in the tub or shower;
• Installing handrails on both sides of stairways;
• Improving lighting throughout the home; and
• Maintaining a regular physical activity program, if your doctor agrees, to improve lower body strength and balance.
• Making living areas safer for children, by:
• Installing window guards to keep young children from falling out of open windows; and
• Using safety gates at the top and bottom of stairs when young children are around.
• Making sure the surface on your child's playground is made of shock-absorbing material, such as hardwood mulch or sand.

TRAUMATIC INCIDENT STRESS

Emergency workers must respond quickly to natural disasters, such as earthquakes or hurricanes, and to manmade disasters, such as technological failures or terrorist attacks. These workers are at risk of experiencing stress from what psychologists refer to as a traumatic incident. A traumatic incident is one that may involve exposure to catastrophic events, severely injured children or adults, dead bodies or body parts, or a loss of colleagues. NIOSH recommends that all workers involved in response activities help themselves and their coworkers and reduce the risk of experiencing stress associated with a traumatic incident by utilizing simple methods to recognize, monitor, and maintain health on-site and following such experiences.

Symptoms of Stress

Workers may experience physical, cognitive, emotional, or behavioral symptoms of stress. Some people experience these reactions immediately at the scene, while for others symptoms may occur weeks or months later.

Physical symptoms

Workers experiencing any of the following symptoms should seek IMMEDIATE medical attention:

• Chest pain
• Difficulty breathing
• Severe pain
• Symptoms of shock (shallow breathing, rapid or weak pulse, nausea, shivering, pale and moist skin, mental confusion, and dilated pupils)

Workers may also experience the following physical symptoms. If these symptoms occur over time or become severe, workers should seek medical attention. Additional physical symptoms include:

• Fatigue
• Nausea/vomiting
• Dizziness
• Profuse sweating
• Thirst
• Headaches
• Visual difficulties
• Clenching of jaw
• Nonspecific aches and pains

Cognitive symptoms

If these symptoms occur on the scene workers may not be able to stay clearly focused to maintain their own safety or to rescue injured victims. Workers may experience momentary cognitive symptoms; however, if symptoms are chronic or interfere with daily activities, workers should seek medical attention. These symptoms include:

• Confusion
• Disorientation
• Heightened or lowered alertness
• Poor concentration
• Poor problem solving
• Difficulty identifying familiar objects or people
• Memory problems
• Nightmares

Emotional symptoms

Strong emotions are ordinary reactions to a traumatic or extraordinary situation. Workers should seek mental health support from a disaster mental health professional if symptoms or distress continue for several weeks or if they interfere with daily activities. Emotional symptoms include:

• Anxiety
• Guilt
• Denial
• Grief
• Fear
• Irritability
• Loss of emotional control
• Depression
• Sense of failure
• Feeling overwhelmed
• Blaming others or self
• Severe panic (rare)

Behavioral symptoms

As a result of a traumatic incident, workers may notice the following behavioral changes in themselves or coworkers:

• Intense anger
• Withdrawal
• Emotional outburst
• Temporary loss or increase of appetite
• Excessive alcohol consumption
• Inability to rest, pacing
• Change in sexual functioning

Recommendations to Monitor and Maintain Health On-Site

Responders need to take care of their own health to maintain the constant vigilance they need for their own safety. Responders must be able to stay focused on the job in the dynamic, changing emergency environment. Often responders do not recognize the need to take care of themselves and to monitor their own emotional and physical health. This is especially true if recovery efforts stretch into several weeks. The following guidelines contain simple methods for workers and their team leaders to help themselves and their team members. These guidelines should be read while at the site and again after workers return home.

Control the organization and pace of the rescue and recovery efforts

• Pace yourself. Rescue and recovery efforts at the site may continue for days or weeks.
• Watch out for each other. Coworkers may be intently focused on a particular task and may not notice a hazard nearby or behind.
• Be conscious of those around you. Responders who are exhausted, stressed, or even temporarily distracted may place themselves and others at risk.
• Take frequent rest breaks. Rescue and recovery operations take place in extremely dangerous work environments. Mental fatigue, particularly over long shifts, can greatly increase emergency workers' risk of injury.

Maintain adequate nutrition and rest

• Eat and sleep regularly. Maintain as normal a schedule as possible and adhere to the team schedule and rotation.
• Drink plenty of fluids such as water and juices.
• Try to eat a variety of foods and increase your intake of complex carbohydrates (for example, breads and muffins made with whole grains, granola bars).
• Whenever possible, take breaks away from the work area. Eat and drink in the cleanest area available.

Monitor mental/emotional health

• Recognize and accept what you cannot change—the chain of command, organizational structure, waiting, equipment failures, etc.
• Talk to people when YOU feel like it. You decide when you want to discuss your experience. Talking about an event may be reliving it. Choose your own comfort level.
• If your employer provided you with formal mental health support, use it!
• Give yourself permission to feel rotten: You are in a difficult situation.
• Recurring thoughts, dreams, or flashbacks are normal—do not try to fight them. They will decrease over time.
• Communicate with your loved ones at home as frequently as possible.

Recommendations to Maintain Health Following the Incident

Over time, workers' impressions and understanding of their experience will change. This process is different for everyone. No matter what the event or an individual's reaction to it, workers can follow some basic steps to help themselves adjust to the experience:

• Reach out—people really do care.
• Reconnect with family, spiritual, and community supports.
• Consider keeping a journal.
• Do not make any big life decisions.
• Make as many daily decisions as possible to give yourself a feeling of control over your life.
• Spend time with others or alone doing the things you enjoy to refresh and recharge yourself.
• Be aware that you may feel particularly fearful for your family. This is normal and will pass in time.
• Remember that "getting back to normal" takes time. Gradually work back into your routine. Let others carry more weight for a while at home and at work.
• Be aware that recovery is not a straight path but a matter of two steps forward and one back. You will make progress.
• Appreciate a sense of humor in yourself and others. It is okay to laugh again.
• Your family will experience the disaster along with you. You need to support each other. This is a time for patience, understanding, and communication.
• Avoid overuse of drugs or alcohol. You do not need to complicate your situation with a substance abuse problem.
• Get plenty of rest and normal exercise. Eat well-balanced, regular meals.

National Occupational Injury Symposium (NOIRS)
The National Occupational Injury Research Symposium (NOIRS) provides a forum for researchers to share their findings related to traumatic occupational injuries. NIOSH, in partnership with the Liberty Mutual Research Institute for Safety and the National Safety Council, hosted NOIRS 2011 on October 18, 19, and 20, 2011.
In 2010, there were an estimated 139,064,000 civilian workers in the U.S. private and public sector employed labor force, according to the Bureau of Labor Statistics Current Population Survey. Each day, many of these workers suffer injury, disability, and death from workplace incidents. In 2010, more than 4,500 U.S. workers died from occupational injuries. Although difficult to enumerate, annually about 49,000 deaths are attributed to work-related illnesses. In 2010, an estimated 3.9 million workers in private industry and state and local government had a nonfatal occupational injury or illness. Of those workers, 2 million were transferred, placed on work restrictions, or took time away from work. In the same year an estimated 2.6 million workers were treated in emergency departments for occupational injuries and illnesses, and approximately 110,000 of these workers were hospitalized (NIOSH, unpublished data, 2012).
Each year occupational injuries and illnesses cause employers, workers, and society to pay tremendous costs for workers’ compensation and other insurance, medical expenses, lost wages and productivity, and the personal and societal costs associated with day to day living for injured and ill workers.  In 2009, employers spent $74 billion on workers' compensation insurance alone.
