众所周知《国际疾病分类-9》(简称ICD-9)亚目的.9通常用于对不确定的诊断编码,所以.9编码的使用应该是有限度的。尤其是在第一诊断中的使用度不应超过特定的范围。但至今国内没有人对这一观点进行过量化研究,本文对我院近六年来4951个病种,129 302份住院病案的出院第一诊断进行分析比较,期望以其中26 806个第一诊断为.9的编码为切入点找到评价编码工作质量直观、合理的标准。 结果:1994年至1999年129 302份病案的编目情况见表1及表2。 It is well known that the sub-purpose .9 of the International Classification of Diseases (ICD-9) is usually used to code indeterminate diagnostics, so the use of .9 codes should be limited. In particular, the degree of use in the first diagnosis should not exceed a specific range. However, no one in China has conducted a quantitative study of this view. This article analyzes and compares the first diagnosis of 4951 cases and 129,302 inpatient cases in our hospital in the past six years, and expects 26,806 first diagnoses to be The .9 code is an entry point to find intuitive and reasonable criteria for evaluating coding quality. Results: The cataloging of 129,302 medical records from 1994 to 1999 is shown in Table 1 and Table 2.
