Workplace injuries caused by commercial fishing winches-Alaska, 2000-2020
Victoroff TM , Case SL , Robertson LD , Syron LN . J Agromedicine 2023 28 (3) 1-11 OBJECTIVES: Deck machinery is a leading source of hospitalized injury for commercial fishing workers in Alaska. More detailed data are needed about the specific circumstances leading to injuries for developing targeted prevention efforts. METHODS: This study analyzed claims submitted to the Alaska Fisherman's Fund (AFF) to identify patterns among injuries in Alaska from commercial fishing winches. RESULTS: During January 1, 2000-November 1, 2020, 125 traumatic injuries from commercial fishing winches were identified, mainly occurring among males (94%), frequently among fishermen aged 30 years or younger (54%). Over 80% of winch injuries occurred in salmon fisheries. By gear type, 40% of injuries occurred on vessels using purse seine gear, 30% on vessels using drift gillnet gear, and 12% among set gillnet operators. Most injuries involved a fisherman having a body part caught in or compressed by a winch or cables attached to a winch (67%). Injuries mainly affected upper extremities including fingers (50% of cases) or hands/wrists (together 22% of cases). Injury severity was not formally assessed, but injuries ranged from contusions, sprains, and strains to finger or hand crushing injuries, upper limb amputation, skull fracture, spinal fracture, and chest trauma. Most cases involved fractures (23%), amputations (18%), lacerations (16%), and contusions (16%). Of all injuries, 51% were caused by anchor winches, 32% were caused by deck winches, 9% were caused by trailer winches, and 9% were caused by other types of winches. CONCLUSIONS: Practical solutions are needed for avoiding entanglement and struck-by hazards when operating fishing winches. Anchor winches warrant focused attention, having accounted for more than half of all winch injuries identified in this study. Engineering solutions, including emergency stop devices or other simple mechanical interventions depending on winch type, could help to avert potentially disabling injuries from winches. Administrative controls such as task-specific training for winches should be emphasized, especially for younger or less experienced commercial fishing crew, who may be at increased risk for injury. |
A novel staging system for caries severity in the primary dentition
Robertson LD , Beltran-Aguilar E , Dasanayake A , Phipps KR , Warren JJ , Hennessy TW . J Public Health Dent 2016 77 (1) 6-12 OBJECTIVES: Caries in the primary dentition (CIPD) has a high prevalence in U.S. children compared to other diseases, with substantial disparities among different population groups. Few reports correlate CIPD prevalence with clinical impairment of children's quality of life, such as tooth pain, speech delay or trauma to the child from operative restorations, which we collectively term morbidity. Likewise, current case definitions (ECC, S-ECC) and disease metrics (mean dmfs/dmft) are not helpful in assessing morbidity for individual or groups of children. We describe a construct to stage caries severity for children ages 0 -5, called "CIPD Levels." This metric is based on small interval age-group dmft scores, and has a direct link to current and predicted morbidity for the child. It is modeled after staging systems for medical diseases in which the various stages or levels are correlated with the probability of morbidity or mortality. METHODS: We created a matrix in which CIPD Levels 0-4 are assigned for dmft scores 0-7 depending on a child's age. CIPD Level-4 is the highest level, and frequently results in clinical adverse outcomes, including pain and extensive restorations. We next tested this matrix with data from a high-risk population. RESULTS: Among children with any cavitated caries at age <24 months, 82.8% reached the adverse outcomes threshold (CIPD Level-4) at age 36 months. For children with dmft = 0 at 24 months, 71.4% did not reach CIPD Level-4 at age 36 months. CONCLUSION: Our new metric is useful for quantifying disease burden from caries for high-risk children. |
