French hospital database, called Programme de Médicalisation des Systèmes d'Information (PMSI), covers all hospital stays in France (>66 million inhabitants). The aim of this study was to estimate the positive predictive values (PPVs) of primary diagnosis codes of peripheral arterial and venous thrombosis codes in the PMSI, encoded with the International Classification of Diseases, 10th revision. Data were extracted from the PMSI database of Toulouse University Hospital, south of France. We identified all the hospital stays in 2015 with a code of peripheral arterial or venous thrombosis as primary diagnosis. We randomly selected 100 stays for each category of thrombosis and reviewed the corresponding medical charts. The PPV of peripheral arterial thrombosis codes was 83.0%, 95% confidence interval (CI): 73.9-89.1, and the PPV of correct location of thrombosis was 81.0%, 95% CI: 72.2-87.5. The PPV of pulmonary embolism was 99.0%, 95% CI: 93.8-99.9. The PPV of peripheral venous thrombosis was 95.0%, 95% CI: 88.2-98.1, and the PPV of correct location of thrombosis was 85.0%, 95% CI: 76.7-90.7. Primary diagnoses of peripheral arterial and venous thrombosis demonstrated good PPVs in the PMSI.
法国医院数据库名为“信息系统医学化计划”（PMSI），涵盖了法国所有住院病例（超过6600万居民）。本研究的目的是估计PMSI中采用国际疾病分类第10版编码的外周动脉和静脉血栓形成编码的初步诊断代码的阳性预测值（PPV）。数据从法国南部图卢兹大学医院的PMSI数据库中提取。我们确定了2015年所有以外周动脉或静脉血栓形成编码作为初步诊断的住院病例。我们为每种血栓形成类别随机选择了100例住院病例，并查阅了相应的病历。外周动脉血栓形成编码的PPV为83.0%，95%置信区间（CI）：73.9 - 89.1，血栓形成正确部位的PPV为81.0%，95%CI：72.2 - 87.5。肺栓塞的PPV为99.0%，95%CI：93.8 - 99.9。外周静脉血栓形成的PPV为95.0%，95%CI：88.2 - 98.1，血栓形成正确部位的PPV为85.0%，95%CI：76.7 - 90.7。外周动脉和静脉血栓形成的初步诊断在PMSI中显示出良好的PPV。
