National Quality Rating Database

Quantros' National Quality Rating Database (NQRD) includes virtually all general, acute, non-federal U.S. hospitals. The database incorporates ten (10) quarters of Medicare Fee for Service (FFS) claims data (January 2014 to June 2016) which runs approximately one (1) year behind the current calendar year. The NQRD includes information from the following publicly available datasets:

  • CMS Medicare Fee for Service claims data which provides the following outcome measures:
    • Actual Mortality Rate
    • Actual Complications Rate
    • Actual All-Site Readmissions Rate
    • Actual Patient Safety Indicator (PSI) Rate
    • Actual Inpatient Quality Indicator (IQI) Mortality Rate

Relying on data from CMS Medicare claims, Quantros applied five (5) separate regression models, which resulted in the addition of the following NQRD value-added data elements:

  • Expected Mortality Rate
  • Expected Complications Rate
  • Expected All-Site Readmissions Rate
  • Expected PSI Rate
  • Expected IQI Mortality Rate
  • Risk-Adjusted Mortality Index™ (RAMI™)
  • Risk-Adjusted Complications Index™ (RACI™)
  • Risk-Adjusted All-Site Readmissions Index™ (RARI™)
  • Risk-Adjusted PSI Index™ (RAPSI™)
  • Global Risk-Adjusted PSI Index™ (G-RAPSI™)
  • Risk-Adjusted IQI Mortality Index™ (RIMI™)

Centers for Medicare and Medicaid Services (CMS) Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) Database which provides patient satisfaction measures on:

  • Overall Hospital Rating
  • Doctor Communication
  • Nurse Communication
  • Staff Responsiveness
  • Medication Explanation
  • Pain Control
  • Hospital Environment (Quietness & Cleanliness)
  • Post-Discharge Information
  • Care Transition

Lastly, the NQRD provides state and national percentiles of performance for each quality measure using a z-value for determining the measure’s level of statistical significance and then calculating a standard score (z-score) to convert all data to a standard normal distribution.
