Bicycle Safety<br />

CDC RECOMMENDS HELMETS<br />

The CDC recommends the use of a properly fitted<br />

helmet, when riding a bicycle, for all ages, to prevent<br />

head and brain injury in case of a crash (2017). Helmets<br />

not only protect against head and brain (TBI) injuries,<br />

which are the leading cause of morbidity and mortality,<br />

but other facial, ocular and dental injuries as well.<br />

Those wearing helmets during a wreck were found to<br />

have a 51% lower risk of TBI, 31% lower risk of facial<br />

fracture and 27% decrease in facial contusions and<br />

lacerations (Joseph et al. 2017).<br />

Cycling can be a fun form of recreation, exercise and<br />

transportation for the whole family to enjoy. However,<br />

cycling is not without risks. There were 840 bicyclists<br />

killed, in the United States, in 2016, (National Highway<br />

Traffic Safety Administration, NHTSA). Seven of these<br />

fatalities were in <strong>Nevada</strong> and accounted for 1.8%<br />

of total traffic fatalities (NHTSA, 2018). The <strong>Nevada</strong><br />

Department of Transportation shows 58% of these<br />

accidents were in the roadway, 13% on sidewalks<br />

and another 13% in intersections (2017). The majority<br />

of bicycle related deaths and one-third of non-fatal<br />

injuries are related to traumatic brain injuries (TBIs). TBIs<br />

tripled when injuries happened to riders not wearing<br />

helmets. In 2012, over 80,000 bicycle related head<br />

injuries were treated in emergency departments across<br />

the US. Helmets have been shown to decrease the risk<br />

of severe head and brain injury by 63-88% (Graves et<br />

al. 2014).<br />

AGE & GENDER RELATED STATISTICS<br />

While one might think children are the ones to<br />

most benefit from helmet use, children accounted for<br />

only 7% of bicyclists killed in traffic collisions in 2016.<br />

In this same time frame, men accounted for 84% of<br />

bicycle fatalities. The largest group of men were 50<br />

to 54 years old and 12% were 55 to 59. Men’s bicycle<br />

fatalities were 5.6 times higher than women’s (NHTSA,<br />

2018). A study conducted between 1997-2013 reported<br />

3.8 million bicycle injuries not ending in death. These<br />

numbers are thought to be just an estimate as only a<br />

fraction of accidents causing injuries are ever reported.<br />

The costs to society related to these statistics include<br />

medical costs, loss of work as well as life or quality of<br />

life. This study found the cost of non-fatal injuries to<br />

be $209 billion and fatalities $28 billion (Science Daily,<br />

2017). Joseph et al. (2017) found that over $2 billion US<br />

healthcare dollars are spent on TBI’s annually.<br />

BE SAFE<br />

• Wear a Proper Fit Helmet<br />

• Wear Light Reflective Clothing<br />

• Be Aware of Your Surroundings<br />

• Know the Law (NRS 484B.760-783)<br />

Bicyclists have the same rights and<br />

responsibilities as other drivers.<br />

HELMET SAFETY & FIT<br />

For helmets to be effective in protection, they must<br />

be a Consumer Product Safety Commission (CPSC)<br />

approved helmet. The CPSC is the standard required<br />

by law, in the United States, for bicycle helmets. This<br />

standard was put in place by the government in 1994<br />

and covers all helmets produced for the US, since 1999<br />

(Bicycle Helmets, 2017).<br />

The CPSC helmet must be properly fit and adjusted.<br />

If the helmet is not properly adjusted it is unstable and<br />

may wobble or rotate. Helmets are made with adjustable<br />

straps, many with an adjustment at the nape of the neck<br />

as well as under the chin affecting stability. Poor stability<br />

compromises the efficacy of the helmet on impact. In one<br />

particular study, children and adolescents were found to<br />

more often wear helmets incorrectly. The correct size,<br />

adjustments, angle or tilt and width of the helmet worn,<br />

was found to be detrimental in its effectiveness. The<br />

helmet should be adjusted to take out the instability, with<br />

straps fastened securely under the jaw.<br />

It is worth seeking fit guidance from a bicycle<br />

technician, in one of the many sports or bicycle shops<br />

in the area. Sufficient helmet fitting was found in less<br />

than half of retail stores (Thai, McIntosh & Pang, 2015).<br />

NURSES GET INVOLVED<br />

Nurses may get involved in one of the many school<br />

bicycle programs or create bicycle safety programs<br />

where they do not exist. Nurses have a wide range<br />

of outreach to educate patients, families and schools<br />

within our communities. For example, one trauma<br />

center was instrumental in developing a program to<br />

keep kids healthy and safe in their community. The<br />

program consists of bicycle safety books, DVD’s,<br />

video games, classroom educational programs as<br />

well as organizing an interactive bicycle safety rodeo.<br />

The safety program provided patients presenting to<br />

the emergency department after crashing, safety<br />

awards for wearing helmets. The positive recognition<br />

reinforces safe behavior (Elwell, Kulp & McCue, 2014).<br />
