The following aggregate data elements are required to be entered for all measures:
Hospital Sample Size
Name: | Hospital Sample Size |
Aggregated For: | All Measures |
Definition: | The count of the number of episodes of care (EOC) records identified 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. This includes both Medicare and Non-Medicare patients in this count. If the hospital’s Quarterly Sampling Frequency = 'Not Sampling' or the measure is not eligible for sampling, the Hospital Sample Size will = the Initial Population. Each measure / measure set’s sample size requirements are outlined in the appropriate version of the Joint Commission’s Specification Manual for Joint Commission National Quality Measures or the Center for Medicare & Medicaid Services' Hospital Outpatient Quality Reporting Specifications Manual. |
Allowable Values: | 1 through 10,000,000 (whole numbers only) Note: Given only aggregate data is being submitted, the Sample Size should not be defaulted to zero when the hospital has Five or Fewer Discharges for the quarter. The actual Hospital Sample Size and remainder of the data elements must be entered. |
