BACKGROUND
This study describes rates of non-fatal fall-injury emergency department (ED) visits and hospitalisations before and after the US 2015 transition from the 9th to 10th revision of the International Classification of Diseases, Clinical Modification (ICD-9-CM to ICD-10-CM).
METHODS
ED visit and hospitalisation data for adults aged 65+ years were obtained from the 2010-2016 Healthcare Cost and Utilisation Project. Differences in fall injury rates between 2010 and 2014 (before transition), and 2014 and 2016 (before and after transition) were analysed using t-tests.
RESULTS
For ED visits, rates did not differ significantly between 2014 and 2016 (4288 vs 4318 per 100 000, respectively). Hospitalisation rates were lower in 2014 (1232 per 100 000) compared with 2016 (1281 per 100 000).
CONCLUSION
Increased rates of fall-related hospitalisations could be an artefact of the transition or may reflect an increase in the rate of fall-related hospitalisations. Analyses of fall-related hospitalisations across the transition should be interpreted cautiously.
背景
本研究描述了美国在 2015 年从国际疾病分类第 9 修订版临床修正版（ICD-9-CM）过渡到第 10 修订版（ICD-10-CM）前后非致命性跌倒损伤急诊（ED）就诊和住院的发生率。
方法
从 2010 年至 2016 年医疗保健成本和利用项目中获得了 65 岁以上成年人的 ED 就诊和住院数据。使用 t 检验分析了 2010 年至 2014 年（过渡前）和 2014 年至 2016 年（过渡前和过渡后）之间跌倒损伤发生率的差异。
结果
对于 ED 就诊，2014 年和 2016 年之间的发生率没有显著差异（分别为每 100000 人 4288 次和 4318 次）。2014 年的住院率（每 100000 人 1232 次）低于 2016 年（每 100000 人 1281 次）。
结论
与跌倒相关的住院率增加可能是过渡的一个人为因素，也可能反映了与跌倒相关的住院率的增加。对过渡期间与跌倒相关的住院率的分析应谨慎解释。
