Teaches students how to use health data, like electronic health records (EHR), hospital discharge records, and administrative claims (e.g., Medicare), for epidemiologic studies. Students will gain an understanding of how health data are generated through healthcare utilization and claims for reimbursement sent to payors from physicians, hospitals, and pharmacies. Students will also learn about coding nomenclature, including ICD-10-CM diagnosis codes, ICD-10-CM and CPT procedure codes, and medication coding systems. Students will be given access to a sample of health data to learn how to identify patient populations, identify comorbidities and other measures of health and healthcare utilization, and conduct studies on healthcare utilization and outcomes. Students will also learn about current hot topics in health data, including common data models, how social determinants of health can impact health data and introduce bias, risk prediction and AI, and data linkage.
