The International Classification of Disease, 10th Revision (ICD-10) did not include a code specific for Amyotrophic lateral sclerosis (ALS) until 2017. Instead, code G12.2 included both ALS and other motor neuron diseases (MND). Our objective was to determine US mortality rates for ALS exclusively by excluding other MND and progressive supranuclear palsy.
All mortality data coded as G12.2 under the pre-2017 rubric were obtained for 2011-2014. Deaths without ALS listed in one of the un-coded cause-of-death fields were excluded. ALS death rates per 100,000 persons were age-adjusted to the 2000 US standard population using the direct method.
The proportion of excluded records coded G12.2 but not ALS was 0.21, resulting in 24,328 ALS deaths. The overall age-adjusted mortality rate was 1.70 (95% CI 1.68-1.72). The rate among males was 2.09 (95% CI 2.05-2.12) and females was 1.37 (95% CI 1.35-1.40). The overall rate among whites was 1.84, blacks 1.03, and other races 0.70. For both sexes and all races, the rate increased with age and peaked among 75-79 year-olds. Rates tended to be greater in states at higher latitudes.
Previous reports of ALS mortality in the United States showed similar age, sex, and race distributions but with greater age-adjusted mortality rates due to the inclusion of other diseases in the case definition. When using ICD-10 data collected prior to 2017, additional review of multiple-cause of death data is required for the accurate estimation of ALS deaths.
直到 2017 年,国际疾病分类第十版(ICD-10)才为肌萎缩侧索硬化症(ALS)专门设置了一个代码。在此之前,代码 G12.2 同时包含 ALS 和其他运动神经元疾病(MND)。我们的目的是通过排除其他 MND 和进行性核上性麻痹,专门确定美国 ALS 的死亡率。
获取了 2011-2014 年期间根据旧分类规则下 G12.2 编码的所有死亡率数据。在未编码的死因字段中未列出 ALS 的死亡被排除在外。使用直接法,根据 2000 年美国标准人口对每 10 万人的 ALS 死亡率进行年龄调整。
被排除的记录比例为编码 G12.2 但不是 ALS 的占 0.21,导致 24328 例 ALS 死亡。总体年龄调整死亡率为 1.70(95%CI 1.68-1.72)。男性的死亡率为 2.09(95%CI 2.05-2.12),女性为 1.37(95%CI 1.35-1.40)。白人的总体死亡率为 1.84,黑人 1.03,其他种族 0.70。对于男性和女性以及所有种族,死亡率随着年龄的增长而增加,并在 75-79 岁年龄段达到峰值。在纬度较高的州,死亡率往往更高。
以前美国 ALS 死亡率的报告显示出相似的年龄、性别和种族分布,但由于在病例定义中包含了其他疾病,因此年龄调整后的死亡率更高。当使用 2017 年前收集的 ICD-10 数据时,需要对多病因死亡数据进行额外审查,以准确估计 ALS 死亡人数。
