Average YPLL per Death
Unintentional injury is a leading cause of death in the United States. While many events resulting in injury and death may be accepted as accidents, it is important to understand they are predictable and preventable. Preventing unintentional injuries and reducing their consequences is a public health goal for the nation and Idaho.
Get Healthy Idaho includes unintentional injury death as a priority, specifically motor vehicle accidents, unintentional falls, and accidental poisoning/drug overdose.
The Centers for Disease Control and Prevention (CDC) defines unintentional injury as “the physical damage that results when a human body is suddenly subjected to energy in amounts that exceed the threshold of physiologic tolerance-or else the result of a lack of one or more vital elements, such as oxygen”.(1) The most common unintentional injuries in the United States are motor vehicle accidents, suffocation, drowning, poisoning, fire/burns, falls, and sports and recreation. The consequences of these include significant impacts on well-being, premature death, poor mental health, and significant healthcare costs.
An individual’s risk of injury and violence may be impacted by many social, personal, economic, and environmental factors.(2) For example, the physical environment, both in the home and community, can affect the rate of injuries related to falls, fires, burns, road traffic incidents, drowning, and violence. Understanding social determinants of health and how they contribute to disparities in injury and violence is key to improving the health and safety of all Americans.
Idaho Unintentional Injury Data
Vital Statistics reports accidents (unintentional injury) as the fourth leading cause of mortality in Idaho. There were 878 unintentional deaths in Idaho in 2017. Sixty-eight percent of deaths were non-transport accidents, while 32 percent were transport-related. Males accounted for 62 percent of all unintentional deaths.(3)
Unintentional injuries were the leading cause of death in Idaho residents 0-44 years of age and 65-85 years of age and older. Motor vehicle crashes were the leading cause of death in ages 1-24 and accidental poisoning was the leading cause of death in ages 25-54. Of the non-transport accidents, the leading cause of mortality was accidental falls (242), accidental poisoning and exposure to noxious substances (200), and accidental poisoning by drugs and other biological substances (184). Idahoans aged 65 and older suffered 88 percent of fall deaths in 2017.
Accidental Drug Poisoning Deaths
Idaho has experienced steadily increasing numbers of drug-overdose deaths that has generally mirrored the national trend. From 2014 to 2018, 1,167 Idaho residents died from a drug overdose. Opioids were frequently implicated in Idaho resident drug-overdose deaths. From 2014 to 2018, 58.7 percent (538) of drug-overdose deaths, in which one or more specific drugs were identified, involved opioids. The actual number of drug-overdose deaths involving opioids is almost certainly underestimated because 21.5 percent of drug-overdose deaths reported no specific drugs.
UNINTENTIONAL INJURY RISK REDUCTION STRATEGIES
Reducing Accidental Motor Vehicle Injury Deaths in Children
Motor vehicle deaths are a leading cause of death among children in Idaho and the United States. According to the CDC, in 2017, 49 percent of 8—12 year children were not buckled up, compared to 36 percent of 4—7 year old’s and 22 percent of children less than 4 years old (with restraint use).4 Almost 50 percent of children riding with unbelted drivers were also unrestrained.(5) Buckling children in age– and size-appropriate car seats, booster seats, and seat belts reduces the risk of serious and fatal injuries. Car seat use reduces the risk for injury in a crash by 71—82 percent for children, when compared with seat belt use alone. Booster seat use reduces the risk for serious injury by 45 percent for children aged 4—8, when compared with seat belt use alone.(6) For older children and adults, seat belt use reduces the risk for death and serious injury by approximately half.(7)
Reducing Accidental Poisoning Deaths
A poison is a substance that can cause illness, injury, or death. They can be swallowed, inhaled, or absorbed through the skin. Adult poisonings are usually drug related and result from overdoses of illegal drugs and legal drugs taken for non-medical reasons, poisoning from legal drugs taken in error or at the wrong dose, and unanticipated effects from prescription drugs for medical and non-medical reasons.(8)
The best ways to prevent accidental drug overdose deaths are to increase access to substance abuse treatment services, increase and maximize use of prescription drug monitoring programs, which are state-run databases that track prescriptions for controlled substances and can help improve opioid pain reliever prescribing, inform clinical practices, and protect patients at risk, and consideration of policy options in relation to pain clinics to reduce prescribing practices that are risky to patients.(9)
Reducing Unintentional Fall Injuries and Deaths
Unintentional falls are not an inevitable consequence of aging and can be prevented. Therefore, it is important to take measures to prevent and reduce risk factors for falls throughout older life stages.(10)
According to the CDC, fall risk factors include lower body weakness, Vitamin D deficiency, difficulty with walking and balance, medicines that affect balance, vision problems, foot pain or poor footwear, and hazards in the home. Most falls are caused by a combination of these factors. To prevent falls, programs such as Idaho’s Fit and Fall Proof™ exercise program are important to help older adults maintain the strength, balance, and mobility needed for normal daily activities. Additional measures include a physician evaluation of fall risk, having vision and balance checked and medications reviewed, and ensuring the home environment is safe from trip and fall hazards, such as poor lighting, loose cords and rugs.(11)
