目的探讨一种可用于对玻璃体切除手术病例进行大样本临床研究的疾病分类方法。方法对429例玻璃体切除手术连续病例的全部ICD-10编码进行分析和归类,统计方法使用描述性统计、频次分析。结果将全部玻璃体切除手术疾病分为相互独立的10类:(1)眼外伤,(2)糖尿病相关眼病,(3)眼内肿瘤,(4)非外伤性眼内炎,(5)视网膜脱离,(6)无视网膜脱离的玻璃体视网膜病变,(7)黄斑病变,(8)白内障/晶体病变,(9)青光眼,(10)其他。ICD编码的出现频次和条目数分别反映了各类疾病在玻璃体切除手术病例中的普遍性和内在病变多样性。结论基于ICD编码的手术疾病分类方法简明、合理,反映了玻璃体切除手术的疾病特征和复杂性,可有效用于对玻璃体切除手术病例的大样本临床研究。
OBJECTIVE: To investigate a method of classification of diseases which can be used in large sample clinical study of vitrectomy cases. Methods All ICD-10 codes of 429 consecutive cases of vitrectomy were analyzed and categorized. Statistical methods used descriptive statistics and frequency analysis. Results All the vitrectomy surgeries were divided into 10 categories: (1) ocular trauma, (2) diabetic related ophthalmopathy, (3) intraocular neoplasms, (4) nontraumatic endophthalmitis, (5) retinal detachment , (6) vitreoretinopathy without retinal detachment, (7) maculopathy, (8) cataracts / crystallography, (9) glaucoma, (10) others. The occurrence frequency of ICD codes and the number of entries respectively reflect the universality and intrinsic lesion diversity of various diseases in vitrectomy cases. Conclusion The classification of surgical diseases based on ICD coding is concise and reasonable and reflects the characteristics and complexity of the vitrectomy surgery. It can be effectively used in the clinical study of large sample of vitrectomy cases.
