在基于医学数据库的研究中，Charlson共病指数常用于控制混杂因素。很少有研究的准确性，从这些数据库中获得的代码。我们研究了丹麦国家患者登记处（NRP）中ICD-10诊断编码对19种Charlson疾病的阳性预测值（PPV）。在1998年1月1日至2007年12月31日期间北方丹麦的所有住院患者中，NRP首次列出诊断为Charlson疾病，我们为每种疾病选择了50名医院接触者。我们回顾了出院小结和病历，以验证NRP诊断，并计算PPV作为确诊的比例。共审查了950份记录。19种Charlson条件的总体PPV为98.0%（95% CI; 96.9，98.8）。PPV范围为82.0%（95% CI; 68.6%，91.4%）（糖尿病伴糖尿病并发症）至100%（单侧97.5% CI; 92.9%，100%）（充血性心力衰竭、外周血管疾病、慢性肺病、轻度和重度肝病、偏瘫、肾病、白血病、淋巴瘤、转移性肿瘤和AIDS）。Charlson条件下NRP编码的PPV始终较高。
The Charlson comorbidity index is often used to control for confounding in research based on medical databases. There are few studies of the accuracy of the codes obtained from these databases. We examined the positive predictive value (PPV) of the ICD-10 diagnostic coding in the Danish National Registry of Patients (NRP) for the 19 Charlson conditions. Among all hospitalizations in Northern Denmark between 1 January 1998 and 31 December 2007 with a first-listed diagnosis of a Charlson condition in the NRP, we selected 50 hospital contacts for each condition. We reviewed discharge summaries and medical records to verify the NRP diagnoses, and computed the PPV as the proportion of confirmed diagnoses. A total of 950 records were reviewed. The overall PPV for the 19 Charlson conditions was 98.0% (95% CI; 96.9, 98.8). The PPVs ranged from 82.0% (95% CI; 68.6%, 91.4%) for diabetes with diabetic complications to 100% (one-sided 97.5% CI; 92.9%, 100%) for congestive heart failure, peripheral vascular disease, chronic pulmonary disease, mild and severe liver disease, hemiplegia, renal disease, leukaemia, lymphoma, metastatic tumour, and AIDS. The PPV of NRP coding of the Charlson conditions was consistently high.
