Definition:

Indicates the number of episode of care (EOC) records identified for a hospital with Medicare listed as a payment source for a hospital to perform data abstraction on. This count is after the appropriate sampling methodology, if any, has been applied for the specific time period.

Notes for discharge measures (eg. HBIPS-1, 4, PC-01):

If the hospital is sampling the discharge measures, then the Sample Size – Medicare Only should be equal or less than the Initial Patient Population Size – Medicare Only for the set, stratum, or sub-population.
If the hospital is not sampling the discharge measures, then the Sample Size – Medicare Only will equal the Initial Patient Population Size – Medicare Only for the set, stratum, or sub-population.

Notes for HBIPS event measures (HBIPS-2 and 3):

Hospitals may not sample the HBIPS event measures. For these two measures, the Sample Size – Medicare Only equals the Initial Patient Population Size – Medicare Only for the set, stratum, or sub-population.
