Swiss Operation Classification (CHOP)

As part of the Medical Statistics of Hospitals, all inpatient hospital stays are recorded. The survey, which is carried out in all hospitals and clinics, includes not only administrative data and sociodemographic characteristics of patients, but also diagnoses and treatments. To capture this information, two medical classifications are used. This is the ICD-10-GM for diagnoses and the Swiss surgical classification (CHOP) for treatments. Encoding of diagnoses and treatments is subject to precise guidelines. The Medical Classifications section of the BFS edits, reviews and adapts these guidelines at best, maintains the above classifications and supports all those involved in coding. The versions 2024 of the systematic and alphabetical registers of the CHOP will enter into force on 1 January 2024 in Switzerland. These directories appear in German, French and Italian as well as in various formats (PDF, CSV, Print). The German version of the systematic directory is the reference version.作为医院医疗统计工作的组成部分，本数据集收录所有住院患者的住院诊疗记录。本次调研覆盖全瑞士所有医院与诊所，采集内容不仅包含患者的行政数据与社会人口学特征，还涵盖患者的诊断与治疗信息。为完整采集上述信息，本次统计采用两套医学分类标准：诊断编码采用ICD-10-GM，治疗编码采用瑞士手术分类标准（CHOP）。诊断与治疗信息的编码工作需遵循严格的规范指南。瑞士联邦统计局（BFS）下属的医学分类部门负责对上述指南进行修订、审核与完善，维护前述两套分类标准，并为所有参与编码工作的人员提供支持。CHOP 2024版系统分类与字母索引目录将于2024年1月1日在瑞士正式生效。该目录提供德语、法语、意大利语三个语言版本，并支持PDF、CSV、印刷版等多种格式。系统分类目录的德语版本为官方参考版本。
