Headphone use and pedestrian injury and death in the United States: 2004-2011. Inj Prev. 2012 Jan 16. [Epub ahead of print]
Uso de auriculares y lesiones y muerte de peatones en los Estados Unidos: 2004-2011
Este trabajo, aunque puede sobre representar los atropellos graves, a cambio no recoge casos de “casi accidente”, en los que el peatón evita lo colisión en el último momento, o en los que las consecuencias son leves.
En cualquier caso pone de manifiesto el peligro que representa estar aislado auditivamente del entorno, así como el factor distracción debido tanto a lo que se está oyendo como a la manipulación táctil del instrumento electrónico.
Background: The association between distraction caused by cell phone use while driving and driver/passenger fatalities has been documented, but the safety risks associated with headphone use by pedestrians remains unknown.
Objective: To identify and describe pedestrian-vehicle crashes in which the pedestrian was using headphones.
Methods: A retrospective case series was conducted by searching the National Electronic Injury Surveillance System, US Consumer Product Safety Commission, Google News Archives and Westlaw Campus Research databases for reports published between 2004 and 2011 of pedestrian injuries or fatalities from crashes involving trains or motor vehicles. Cases involving headphones were extracted and summarised. The likelihood of headphone involvement was graded on a three-tier scale based on the information found in the article or report.
Results: There were 116 reports of death or injury of pedestrians wearing headphones. The majority of victims were male (68%) and under the age of 30 (67%). The majority of vehicles involved in the crashes were trains (55%), and 89% of cases occurred in urban counties. 74% of case reports stated that the victim was wearing headphones at the time of the crash. Many cases (29%) mentioned that a warning was sounded before the crash.
Conclusions: The use of headphones with handheld devices may pose a safety risk to pedestrians, especially in environments with moving vehicles. Further research is needed to determine if and how headphone use compromises pedestrian safety.
