ABSTRACT
Aims: Traumatic injury is one of the leading causes of death in all age groups. Ensuring adequate and effective access to trauma centers is key to improving the quality of care for injured patients. This study evaluates the spatial accessibility of Ohio trauma centers and identifies potentially underserved Ohio counties. Study Design: A gravity based accessibility model using a Geographic Information System (GIS) was implemented. Place and Duration of Study: The study was conducted in Nationwide Children’s Hospital in 2015. Methodology: A gravity based accessibility model using a Geographic Information System (GIS) was adapted to incorporate US census data, trauma center location data, and trauma center utilization data to quantify accessibility to trauma centers at both the zip code and county levels. An underserved index was developed to identify the location and clustering pattern of underserved regions within the state. Results: Most served counties were about 10 times more served than an average county while least served counties were about 4 times less served than an average county. Conclusion: Findings of this study are potentially useful for evaluating regionalized trauma care and provide evidence for trauma care system improvements.
ABSTRACT
Objective To explore the risk factors on cases regarding work-related acute pesticide poisoning among farmers of Jiangsu province.Methods A population-based,1 ∶ 2 matched case-control study was carried out,with 121 patients as case-group paired by 242 persons with same gender,district and age less then difference of 3 years,as controls.Cases were the ones who had suffered from work-related acute pesticide poisoning.A unified questionnaire was used.Data base was established by EpiData 3.1,and SPSS 16.0 was used for both data single factor and multi-conditional logistics regression analysis.Results Results from the single factor logistic regression analysis showed that the related risk factors were:lack of safety guidance,lack of readable labels befores praying pesticides,no regression during application,using hand to wipe sweat,using leaking knapsack,body contaminated during application and continuing to work when feeling ill after the contact of pesticides.Results from multi-conditional logistic regression analysis indicated that the lack of safety guidance (OR=2.25,95％ CI:1.35-3.74),no readable labels befores praying pesticides (OR=1.95,95％ CI:1.19-3.18),wiping the sweat by hand during application (OR=1.97,95％CI:1.20-3.24)and using leaking knapsack during application (OR=1.82,95％ CI:1.10-3.01) were risk factors for the occurrence of work-related acute pesticide poisoning.Conclusion The lack of safety guidance,no readable labels befores praying pesticides,wiping the sweat by hand or using leaking knapsack during application were correlated to the occurrence of work-related acute pesticide poisoning.
