Background:
Seafarers are an understudied and essential workforce, isolated from medical care. This study describes injuries, illness, and risk factors for resultant disability in one shipping company with a majority of American seafarers.
Methods:
The study used a telemedicine database of injury and illness incidence in seafarers, and applied descriptive statistical methods and logistic regression modeling.
Results:
Illnesses were more frequently reported than injuries (860 vs 479). The overall injury rate was 113 per 1000 person-years, and the overall illness rate was 211 per 1000 person-years. Seafarer ratings had higher risk for disability compared to officers (OR = 1.60; 95%CI 1.17, 2.18), and incidents on dry cargo ships (OR = 2.70; 95%CI 1.49, 4.91) and articulated tug-barges (ATBs) (OR = 2.21; 95%CI 1.26, 3.86) had higher disability risk compared to container vessels.
Conclusion:
Additional research in this vital American workforce may be useful to confirm these findings forming a basis for preventive interventions.

Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...
