Retrospective analysis of electronic health records of patients with heart failure: the first Russian experience

Abstract

The article presents the first experience of analyzing the treatment quality of hospitalized patients with heart failure based on electronic health records (EHR). We analyzed EHR of patients hospitalized in three large hospitals in Kirov. The results of the analysis indicated insufficient detailed information in the EHR, which complicates analyzing the accuracy of diagnosis and therapy quality. In particular, attention is drawn to the disproportionate number of patients with heart failure with reduced and preserved ejection fractionю This, apparently, is due to the low prevalence of assessing brain natriuretic peptides and conducting Doppler echocardiography. A separate part of the analysis is devoted to assessing the therapy quality in patients with concomitant diabetes. Despite the study limitations, the presented results can be useful for improving the quality of EHR filling for performing further observational clinical trials.

Approaches to Assessing the Quality of Observational Studies of Clinical Practice Based on the Big Data Analysis

“…Это обусловлено, например, тем, что ЭМК заполняют разные врачи, и такие записи могут различаться по подробности и точности. Более того, по разным причинам некоторые данные могут быть пропущены, а сами данные отражают лишь те показатели, которые регистрируют в клинической практике [10]. Не так давно стали учитывать и данные, предоставляемые самими пациентами, включая оценку ими симптомов заболевания в условиях повседневной жизни.…”
