Detailed narrative of logic

1. This logic begins with the PDC Measure Fills synthetic object which is one record per patient - calendar date - ingredient triple for a targeted PDC medication; includes information on the medication therapy episode containing that fill.
2. Next, for each episode in PDC Measure Fills, the distinct count of fills for Oral Antidiabetics, Oral ACEI/ARBs, and Statins are calculated.
3. Finally, the object is collapsed to records containing at least one active (in-supply) medication.
