Ideal Data Structure
This diagram shows the ideal data structure for linking data across sources at the dialysis facility level. Each source file has a record for each facility, and the source file formats remain consistent over time. Fitting the pieces together for reporting and analysis is very easy using simple tools like Excel.

Fitting the pieces together requires in-depth content knowledge of the data structures, numbering schemes, variable definitions, and data quality pitfalls. Data joins are multivariate complex.
