This paper examines the quality of routinely collected information in an Iranian hospital in a trial of casemix classification. Australian Refined Diagnosis Related Groups (AR-DRG) were used to classify patient episodes. There were 327 DRGs identified, of which 20% had only 1 case. The grouper program identified invalid records for 4% of total separations. Approximately 4.5% of cases were classified into error DRGs and 3.4% were ungroupable. No complication and comorbidity effects were identified with 93% of total cases. R2 (variance in length of stay explained) was 44% for untrimmed cases, increasing to 63%, 57% and 58% after trimming by L3H3, IQR and 10th-95th percentile methods respectively.
本文考察了伊朗一家医院在病例组合分类试验中常规收集信息的质量。使用澳大利亚精细化诊断相关分组 (AR-DRG) 对患者病例进行分类。共确定了 327 个 DRG，其中 20%只有 1 例。分组程序为 4%的总出院病例识别出无效记录。大约 4.5%的病例被归入错误 DRG，3.4%的病例无法分组。93%的病例未发现并发症和合并症影响。未修剪病例的 R2（解释住院时间方差）为 44%，分别使用 L3H3、IQR 和 10 百分位-95 百分位方法修剪后，增加至 63%、57%和 58%。
