evidence: The aging motorcyclist: a comparative epidemiologic study on pattern and severity of injury - PMID: 22743387 - DOI: 10.1097/TA.0b013e31824acc08 The aging motorcyclist: a comparative epidemiologic study on pattern and severity of injury [...] Conclusions: Advanced age demonstrated correlation with prolonged hospital stay and requirement of more aggressive medical care. An increased risk of mortality was demonstrated for the older motorcyclist. However, age alone did not affect the severity or distribution of orthopedic injuries in this study. As the motorcycle riding population ages, it is important to understand the injuries and hospital course of these patients, along with the increased mortality rates and health care expenditure burden which can be expected.
