Measurement Approach

WCHQ Measurement Approaches

WCHQ publicly reports a broad collection of health care performance measures that evaluate ambulatory and hospital care.

Measures are publicly reported at WCHQ.org.

WCHQ member organizations — which include health systems, medical and dental groups and hospitals — voluntarily collect and submit data related to the services that they provide. WCHQ validates the data, ensuring that it accurately reflects evidence-based standards. WCHQ then publishes the results so health care providers, purchasers and consumers can compare the performance of member organizations.

Public reporting has been shown to stimulate and catalyze improvement and encourage greater efficiency among health care providers.

WCHQ's Unique Approach: All Patients, All Payers

Many other health care reporting organizations rely exclusively on administrative claims from commercial insurers to create their performance measures. Such claims-based reports exclude Medicare, Medicaid and self-pay patients, which account for nearly 50 percent of clinical practice.

Physicians, data analysts and improvement specialists from the WCHQ membership have developed ambulatory care specifications that capture all patients and all payers. By uniting claims, clinical and patient data, WCHQ tracks each provider's entire practice. This comprehensive approach enables WCHQ to create a sophisticated measure set that evaluates both clinical processes and intermediate outcomes, such as A1c and blood pressure.

Innovative Data Submission

WCHQ created an innovative submission tool that allows WCHQ member organizations to directly submit patient-level data files for processing and reporting.

This data submission tool provides important benefits for WCHQ members:

  • Time savings when querying and aggregating data;
  • Increased efficiency during data validation;
  • Reduced programming burden; and,
  • Ready access to patient level data for internal testing and reporting.

When members submit data, they create a global file of patient demographic, encounter and clinical data. This global file encompasses data from all available sources, including electronic health record software, billing systems, lab information and medication lists.

Once WCHQ members upload their global data, the WCHQ system's centrally programmed measure specifications calculate performance results for both public reporting on the WCHQ website and custom reporting within member organizations.

The WCHQ data submission and storage processes comply with HIPAA regulatory requirements, as verified by independent audit.
