Abstract

Objective The study assesses the validity of ICD-10 coded cardiovascular risk factors in claims data using gold-standard measurements from a population-based study for arterial hypertension, diabetes, dyslipidemia, smoking and obesity as a reference. Methods Data of 1941 participants (46 % male, mean age 58 +/- 13 years) of the Study of Health in Pomerania (SHIP) were linked to electronic medical records from the regional association of statutory health insurance physicians from 2008 to 2012 used for billing purposes. Clinical data from SHIP was used as a gold standard to assess the agreement with claims data for ICD-10 codes I10.- (arterial hypertension), E10.- to E14.- (diabetes mellitus), E78.- (dyslipidemia), F17.- (smoking) and E65.- to E68.- (obesity). Results A higher agreement between ICD-coded and clinical diagnosis was found for diabetes (sensitivity (sens) 84 %, specificity (spec) 95 %, positive predictive value (ppv) 80 %) and hypertension (sens 72 %, spec 93 %, ppv 97 %) and a low level of agreement for smoking ( sens 18 %, spec 99 %, ppv 89 %), obesity (sens 22 %, spec 99 %, ppv 99 %) and dyslipidemia (sens 40 %, spec 60 %, ppv 70 %). Depending on the investigated cardiovascular risk factor, medication, documented additional cardiovascular co- morbidities, age, sex and clinical severity were associated with the ICD-coded cardiovascular risk factor. Conclusion The quality of ICD-coding in ambulatory care is highly variable for different cardiovascular risk factors and outcomes. Diagnoses were generally undercoded, but those relevant for billing were coded more frequently. Our results can be used to quantify errors in population-based estimates of prevalence based on claims data for the investigated cardiovascular risk factors.
