This study was undertaken (i) to determine in-hospital case-fatality rates (CFRs) by severity using body part(s) affected as a proxy, and (ii) to examine the trends in hospitalized burns regarding CFRs. The study used the Health Service Cost Review Commission non-confidential Maryland hospital discharge data for the years 1981-90. CFRs were computed as percentages of hospitalized burns that died. Chi-square tests were used to assess homogeneity for categorical variables and to examine linear trends. The CFR for hospitalized burns was 2.9 per cent. CFR was highest among the elderly (13.1 per cent) and for burns affecting multiple specified sites (7.4 per cent), and lowest among children (1.1 per cent) and for upper limb burns (0.22 per cent). Burn CFR increased overall by 59 per cent for 1981-90, with a decreasing rate only in children. However, after controlling for age and degree of burn no significant change in trend in CFRs over the 10-year period was evident. The findings demonstrate that while child burn fatality seems to have declined, the elderly continue to have high CFR for burns regardless of the body part affected, and that the CFRs for hospitalized burns remained constant between 1981 and 1990 in Maryland despite considerable advances in treatment.
（i）以受影响的身体部位为替代指标，按严重程度确定住院病死率（CFR）；（ii）研究住院烧伤患者病死率的变化趋势。该研究使用了健康服务成本审查委员会提供的1981 - 1990年马里兰州医院非保密出院数据。CFR计算为住院烧伤死亡病例的百分比。卡方检验用于评估分类变量的同质性并检验线性趋势。住院烧伤患者的CFR为2.9%。CFR在老年人中最高（13.1%），在影响多个特定部位的烧伤中也较高（7.4%），而在儿童中最低（1.1%），在上肢烧伤中最低（0.22%）。1981 - 1990年期间，烧伤CFR总体上升了59%，仅儿童的CFR呈下降趋势。然而，在控制年龄和烧伤程度后，10年间CFR的趋势没有明显变化。研究结果表明，虽然儿童烧伤死亡率似乎有所下降，但老年人无论烧伤身体部位如何，病死率仍然很高，而且尽管治疗取得了显著进展，但1981年至1990年期间马里兰州住院烧伤患者的CFR保持不变。
