Task 1: Introduction: Limitations of CMS data

Before you begin an analysis using the National Health and Nutrition Examination Survey (NHANES) and Centers for Medicare & Medicaid Services (CMS) linked data, it is important to consider a variety of analytic issues.  In this task some data limitations for you to consider prior to data analysis will be discussed (e.g., gaps in coverage, lack of claims data, unreported costs, and differences in state Medicaid programs).
