A one-year prospective survey was conducted to study the incidence of and potential risk factors for farm-related injuries in Eastern Ontario. One hundred and seventeen dairy and beef farms were surveyed using a personal interview. Information was collected on demographic characteristics of the farm owners, workers, and families; characteristics of the farm operations; and information on behaviors potentially affecting injury risk. Monthly telephone contact was then maintained with the farms for one year in order to document all farm-related injuries. Overall and specific injury rates were calculated. Treatment patterns for these injuries were described. The statistical significance of several potential risk factors for injury was evaluated; assessment of relative risk estimates (RR) and adjustment for confounding factors was done using logistic regression analysis. The overall farm injury rate was 7.0 persons injured per 100 person-years (95% C.I.: 4.9,9.1, n = 547). Common patterns of injury by ICD-9-E-Code included accidents caused by farm machinery (E919.0), accidental falls (E880-8), and injuries caused by animals (E906). Variables found in multivariate logistic models to be predictive of injury occurrence were living on a beef farm (RR = 2.5; p = 0.01); increased farm work experience (trend: p less than 0.01); full-time exposure to farm work (RR = 2.5; p = 0.04); and, in farm owners, the use of prescriptions medications (RR = 2.7; p = 0.07). Forty-six percent of the farm-related injuries were treated in a hospital-based emergency department (ER). Efforts to monitor the incidence of farm injuries using an ER-based information system have the potential to significantly under-estimate the scope of the regional farm injury problem in Eastern Ontario.
开展了一项为期一年的前瞻性调查，以研究安大略省东部与农场相关伤害的发生率及潜在风险因素。通过个人访谈对117个奶牛场和肉牛场进行了调查。收集了有关农场主、工人及其家庭的人口统计学特征；农场经营的特征；以及可能影响伤害风险的行为信息。随后，与这些农场保持了为期一年的每月电话联系，以记录所有与农场相关的伤害情况。计算了总体伤害率和特定伤害率，并描述了这些伤害的治疗模式。评估了几种潜在伤害风险因素的统计学意义；使用逻辑回归分析对相对风险估计值（RR）进行了评估，并对混杂因素进行了校正。农场总体伤害率为每100人年有7.0人受伤（95%置信区间：4.9, 9.1；n = 547）。根据国际疾病分类第九版扩展编码（ICD-9-E-Code），常见的伤害类型包括农场机械导致的事故（E919.0）、意外跌倒（E880 - 8）以及动物造成的伤害（E906）。在多变量逻辑模型中发现可预测伤害发生的变量包括：居住在肉牛场（RR = 2.5；p = 0.01）；农场工作经验增加（趋势：p < 0.01）；全职从事农场工作（RR = 2.5；p = 0.04）；以及农场主使用处方药（RR = 2.7；p = 0.07）。46%的与农场相关伤害在医院急诊科（ER）接受治疗。利用基于急诊科的信息系统监测农场伤害发生率的努力，有可能显著低估安大略省东部地区农场伤害问题的范围。
