Laika is an open source electronic health record (EHR) testing framework that was designed and developed by the MITRE Corporation. Laika analyzes and reports on the interoperability capabilities of EHR systems. This includes the testing for certification of EHR software products and networks. To support EHR data interoperability testing, Laika is designed to verify the input and output of EHR data against nationally recognized data and transport standards.

The National Proposed Rulemaking (NPRM) for EHR Incentives issued by CMS provides a reimbursement incentive for eligible professionals (EP) and eligible hospitals that are successful in becoming “meaningful users” of an electronic health record (EHR). Included are a number of measures pertaining to clinical quality of a patient population.

A collection of standards, protocols, legal agreements, specifications, and services that enables the secure exchange of health information over the internet. The NHIN is a key component of the nationwide health information technology strategy and will provide a common platform for health information exchange across diverse entities, within communities and across the country, helping to achieve the goals of the HITECH Act.

The 2006 Tax Relief and Health Care Act required the establishment of a physician quality reporting system, including an incentive payment for eligible professionals (EPs) who satisfactorily report data on quality measures for covered professional services furnished to Medicare beneficiaries during the second half of 2007. CMS named this program the Physician Quality Reporting Initiative (PQRI). The PQRI was further modified as a result of the Medicare, Medicaid, and SCHIP Extension Act of 2007 and the Medicare Improvements for Patients and Providers Act of 2008

The HL7 Quality Reporting Document Architecture standard.

A QRDA Category I report is an individual patient-level quality report. Each report contains quality data for one or more quality measures, where the data elements in the report are defined by the particular measure(s) being reported on. A QRDA Category I report contains raw applicable patient data. When pooled and analyzed, each report contributes the quality data necessary to calculate population measure. The current version of the CMS EHR Warehouse accepts only QRDA Category I reports.

A QRDA Category III report is an aggregate quality report. Each report contains calculated summary data for one or more measures for a specified population of patients within a particular health system over a specific period of time. Whereas a QRDA Category I report contain data for individual patients, a QRDA Category III report only contains calculated data (e.g., number of meeting numerator criteria, number of meeting denominator criteria) on the population.
