This research explored the usage of activity codes introduced into the International Statistical Classification of Diseases and Related Health Problems, Tenth revision, Australian Modification (ICD-10-AM) Third Edition and examined the data quality of activity coding, explicitly, completeness and specificity. Injury separations for years 2001/02 to 2005/06 specifying a 'true injury' were extracted for descriptive analyses. Part A investigated the usage of activity codes and compared the usage of the 236 activity codes available in the Activity block (U50-U73) present in the ICD-10-AM Third Edition against the 16 codes present in the second edition. Part B examined the level of completeness of external cause coding and the degree of activity coding specificity in the 2005/06 dataset. It was found that the additional activity codes were used extensively with only 46 codes seldom assigned. Codes present in the second edition were extensively used in the third and fourth editions and the new additional activity codes represent 10% of all activity codes assigned per year. All five datasets demonstrated high levels of completeness, recording completeness levels greater than 97%, where missing activity codes attributed to the majority of missing codes. Fourteen out of the 24 activity categories demonstrated a strong reliance on non-specific codes and Team ball sports and Wheeled non-motor sports illustrated that activity codes assigned lacked detail in the code. Clinicians and coders need to acknowledge the importance of quality clinical documentation for research and policy-making purposes so that circumstances surrounding injury events can be coded to the highest level of specificity to improve injury prevention and control activities. Missing activity codes and the abundance of non-specific coding hinders the usefulness of the data.
本研究探讨了在国际疾病分类第十版澳大利亚修订版（ICD-10-AM）第三版中引入的活动代码的使用情况，并检查了活动编码的数据质量，特别是完整性和特异性。对于 2001/02 年至 2005/06 年指定“真实损伤”的损伤分离数据，我们进行了描述性分析。第一部分调查了活动代码的使用情况，并将第三版 ICD-10-AM 中活动块（U50-U73）中可用的 236 个活动代码的使用情况与第二版中的 16 个代码进行了比较。第二部分检查了 2005/06 年数据集中外因编码的完整性水平和活动编码特异性程度。结果发现，新增的活动代码得到了广泛的应用，只有 46 个代码很少被分配。第二版中的代码在第三版和第四版中得到了广泛应用，新增的活动代码占每年分配的活动代码的 10%。所有五个数据集都表现出了很高的完整性水平，记录的完整性水平都大于 97%，其中大部分缺失的活动代码归因于缺失的代码。在 24 个活动类别中，有 14 个类别强烈依赖于非特异性代码，团队球类运动和轮式非机动运动表明，分配的活动代码缺乏细节。临床医生和编码员需要认识到高质量临床文档对于研究和决策制定的重要性，以便能够以最高的特异性对损伤事件进行编码，从而提高损伤预防和控制活动的效果。缺失的活动代码和大量非特异性编码阻碍了数据的可用性。
