Risk factors for mortality and length of hospital stay in elderly burn patients are well established, but the influence of race and socioeconomic status has not been evaluated. This study evaluates the effect of neighborhood level socioeconomic indicators on burns risk, and determines whether race and neighborhood influence burn injury outcomes in the elderly. Data from the North Carolina Jaycee Burn Center was linked to United States Census Bureau block group socioeconomic data. The odds of death and increased length of hospital stay for European-Americans and Minorities were determined using logistic regression. Rates of burn were determined using Poisson regression, and multilevel modeling was used to evaluate the influence of neighborhood on outcomes. No significant differences in mortality were observed between European-American and Minority patients in individual (Minority OR 0.71; p=0.3200) and multilevel (0.72; p=0.4020) models. Minorities had significantly higher odds of increased length of hospital stay in individual (2.05; p=0.0020) and multilevel (2.55; 0.037) models. High proportions of rural households (RR=1.39; p=0.0010) and poverty (1.26; p<0.0001) were significantly associated with increased risk of burn. Additional investigation using larger databases will allow further elucidation of the contextual effects of socioeconomic status on burn in the elderly.
老年人烧伤患者的死亡率和住院时间的风险因素已经得到很好的确定，但种族和社会经济地位的影响尚未得到评估。本研究评估了社区层面社会经济指标对烧伤风险的影响，并确定种族和社区是否会影响老年人烧伤的结局。将北卡罗来纳州 Jaycee 烧伤中心的数据与美国人口普查局街区组社会经济数据相关联。使用逻辑回归确定欧洲裔美国人和少数族裔患者死亡和住院时间延长的几率。使用泊松回归确定烧伤发生率，并使用多层次模型评估社区对结局的影响。在个体（少数民族 OR 0.71；p=0.3200）和多层次（0.72；p=0.4020）模型中，欧洲裔美国人和少数民族患者的死亡率没有显著差异。少数民族患者在个体（2.05；p=0.0020）和多层次（2.55；0.037）模型中住院时间延长的几率显著更高。农村家庭比例高（RR=1.39；p=0.0010）和贫困（1.26；p<0.0001）与烧伤风险增加显著相关。使用更大的数据库进行进一步调查将有助于进一步阐明社会经济地位对老年人烧伤的背景影响。
