Approach for Electronic Medical Record Data Analysis

As the healthcare environment is being digitalized and changed rapidly, research using medical big data increasing. One of most applicable electronic records which can provide a large amount clinically practical meaning. Electronic include patient’s demographic information, laboratory test results, imaging biosignal data. In this article, we support for wide variety researchers in their efforts to use record accurately usefully work. From basic concept challenging aspects like integration between multiple institutions are described. Also, examples each type covered; structured such as numeric unstructured images, biosignals narrative text. Using these kinds records, analyses processed by cleansing, transforming, reducing order. Many variables exposure outcome interest, covariate design be chosen during preprocessing. many machine-learning-based studies well epidemiologic-based have been conducted various frameworks proposed. However, quality management standardization multicenter analysis still remaining tasks.
