ICD-10 hospital discharge diagnosis codes were sensitive for identifying pulmonary embolism but not deep vein thrombosis

Hospital discharge data can be used for monitoring procedures and intensive care related to severe maternal morbidity

“…Our study is one of the first to estimate the validity of hospital administrative databases in Europe [15,19,26]. Although the only moderate validity of the hospital data means that research cannot be based exclusively on them, it appears likely that the system in France will improve.…”

“…They are relatively sparse in Europe. Such studies in France have covered the fields of oncology [4,10,23,24], intensive care [25], and vascular disease [26] but not obstetrics.…”

Comparative Analysis of Patients with Acute Coronary and Cerebrovascular Syndromes from the National French Hospitalization Health Care System Database

“…A further restriction was that our analyses were based on prospectively collected administrative data. Despite the fact that such an approach has been demonstrated to be reliable [21][22][23][24] , there may have been some coding errors. The diagnosis of ACS and CVS was made by practitioners and based on clinical examinations supported by complementary exams according to each hospital's resources, with various degrees of expertise in stroke or coronary artery disease.…”

The incidence of diabetes mellitus following pulmonary embolism: a retrospective cohort study

“…An ÔunlikelyÕ Wells score combined with a negative D-dimer test safely excludes PE in 20-40% of patients with suspected PE [10]. Of the remaining patients in whom a CT scan should be performed in order to either exclude or confirm PE, only 20-30% have a positive CT scan for PE [11]. CT scanning is thus indicated in the case of a ÔlikelyÕ Wells score or a positive D-dimer test [3].…”

“…The diagnosis of pulmonary embolism was derived from ICDcodes, which could raise concern about accuracy and may contribute to selection bias. However, Casez et al [11] recently showed that ICD discharge diagnosis codes yield sufficient sensitivity for identifying objectively confirmed PE. Furthermore, subjects diagnosed with DM and treated with diet only are not identifiable as DM subjects in our prescription drugbased database.…”
