Glossary

A case presentation is a formal communication between health care professionals (e.g., physicians, pharmacists, nurses, therapists, nutritionists) providing a synthesis of a patient's clinical information. Components of a case presentation typically include identifying information, reason for consultation/admission, chief complaint (in the patient's own words), recent history, active medical problems, medications, allergies, social history, physical examination findings, relevant test results, assessment, and treatment plans.

Clinical Decision Support (CDS) Connect is a freely available web-based platform, including an authoring tool and a repository, enabling the CDS community to identify evidence-based care, translate and codify information into an interoperable health information technology standard, and leverage tooling to promote a collaborative model of CDS development.

Clinical Decision Support (CDS) Hooks is a Health Level Seven International® (HL7®) specification managed by the HL7 Clinical Decision Support (CDS) Workgroup providing a way to embed additional, near real-time functionality within a clinician’s workflow of an electronic health record. A specified event(s) within the clinician’s workflow triggers the CDS service, which gathers the appropriate specified data elements through secure Fast Healthcare Interoperability Resources® (FHIR®) services. By utilizing FHIR services, CDS Hooks provides interoperability between multiple stakeholders operating on different platforms.

The FHIR service app can return appropriate guidance, such as proposed alternative medication or formulary information. CDS Service vendors can test CDS Service functionality using the CDS Hooks Sandbox. More advanced functionality is under development, such as the multi-interested party Da Vinci Burden Reduction Project and provides use cases for alerts/notifications, prior authorization, and document exchange. The Agency for Healthcare Research and Quality's CDS Connect Project provides a web-based platform to assist with development of CDS artifacts and CDS Hooks.

The Certified Health Information Technology (IT) Product List (CHPL) is a comprehensive and authoritative listing of all certified health information technology that have been successfully tested and certified by the ONC Health IT Certification Program. All products listed on the CHPL have been tested by an ONC-Authorized Testing Laboratory (ONC-ATL) and certified by an ONC-Authorized Certification Body (ONC-ACB) to meet criteria adopted by the Secretary of the Department of Health and Human Services (HHS). For additional information on how to navigate the CHPL, please refer to the CHPL Public User Guide.

ClinFHIR is an open-source tool providing an educational environment and also allows health information technology developers to create or search for Fast Healthcare Interoperability Resources® (FHIR®)-based resources. It serves as a training tool to help people wanting to learn more about FHIR visualize how the parts combine to represent clinical information in a structured and coded manner. It also serves as a development tool with features to build some of the required artifacts, particularly as an aid to learning.

Clinical decision support is health information technology functionality building upon the foundation of an electronic health record to provide persons involved in care processes with general and person-specific information, intelligently filtered and organized, at appropriate times, to enhance health and health care.

Clinical decision support alert fatigue occurs when a clinician, after receiving too many alerts or reminders, begins to override or ignore further alerts without attending to them, thus potentially decreasing the care improvements expected from the tools.

The most commonly implemented clinical decision support (CDS) alerts prompt clinicians about guidance, e.g., drug-allergy, drug-drug, and drug-disease warnings, or provide dosing guidance. Passive CDS includes order sets, patient data reports, and documentation templates while active CDS includes rules and alerts usually delivered through computerized provider order entry or other functions of the electronic health records.

A clinical decision support (CDS) developer is an individual or organization that translates knowledge to a structured and/or executable tool aiding in making evidence-informed decisions about a patient’s health care. CDS developers may or may not be the original knowledge authors (e.g., guideline developers, subject matter experts) or the final implementers. They ensure accurate and consistent reflection of the original clinical knowledge in the appropriate standard coding schemes (e.g., Clinical Quality Language and terminologies such as Current Procedural Terminology and SNOMED CT), accounting appropriately for intellectual property and licensing.

Clinical decision support (CDS) implementation activities refer to configuration, customization, and other needed steps for health information technologies to function for a specific organization or group of end-users. For example, with CDS, the local implementation will consider end-user workflows to identify the points at which to present the CDS, determine which data fields in local databases will map to data fields that drive the CDS, and educate end-users about important features of the CDS. Typically, this involves translation of guideline recommendations from L3 to L4 or other local adaptation (localization) (See Levels of knowledge representation for CPG).

Clinical Document Architecture (CDA) is a popular, flexible markup standard developed by Health Level Seven International® defining the structure of certain patient medical records, such as discharge summaries and progress notes, as a way to better exchange this information between health care providers and patients.

Clinical information systems "are computer systems that provide immediate access to current patient data regarding clinical notes, medication history, laboratory reports, images, and reports either directly or via data networks. They are parts of a hospital information system, which facilitates direct patient care." Islam, M. M., Poly, T. N., & Li, Y-C. J. (2018). Recent advancement of clinical information systems: Opportunities and challenges. Yearbook of Medical Informatics, 27(1), 83–90. https://www.thieme-connect.com/products/ejournals/abstract/10.1055/s-0038-1667075

Clinical practice guidelines (CPGs) are systematically developed statements to assist clinician and patient decisions about appropriate health care for specific clinical circumstances. CPGs are statements that include recommendations intended to optimize patient care. They are informed by a systematic review of evidence and an assessment of the benefits and harms of alternative care options. Committee on Standards for Developing Trustworthy Clinical Practice Guidelines. (2011). Clinical practice guidelines we can trust. Institute of Medicine. https://www.ncbi.nlm.nih.gov/books/NBK209539/pdf/Bookshelf_NBK209539.pdf  

A clinical quality measure (CQM) is a mechanism used for assessing the degree to which a clinician competently and safely delivers clinical services appropriate for the patient in an optimal time frame. CQMs are a subset of the broader category of quality measures.

CMS Measures Inventory Tool (CMIT) is the repository of record for information about CMS quality measures. CMS and its partners use the inventory to inform stakeholders, manage its measure portfolio, and guide measure development. The functions allow users to find measures quickly, compile and refine sets of related measures, identify measures across the continuum of care, and help coordinate measurement efforts across all conditions, settings, and populations.

The CMS consensus-based entity (CBE) assigns the CMS CBE identification number to a measure that has successfully gone through the CBE endorsement process. The CMS CBE Submission Tool and Repository (STAR) is the database of record of CBE-endorsed measures. 

The Medicare Improvements for Patients and Providers Act of 2008 requires the U.S. Department of Health and Human Services to contract with a consensus-based entity (CBE) regarding performance measurement. The CMS CBE endorses quality measures through a transparent, consensus-based process incorporating feedback from diverse groups of interested parties to foster health care quality improvement.

The CBE also convenes multi-interested party groups to discuss the Measures Under Consideration List as part of the pre-rulemaking process and reviews CMS's existing measure portfolio for possible change recommendations.

The CMS Data Element Library (DEL) is the centralized resource for CMS assessment instrument data elements (e.g. questions and responses) and their associated health information technology standards. It currently includes CMS's post acute care assessment instruments.

When a measure developer creates a new electronic clinical quality measure in the Measure Authoring Development Integrated Environment (MADiE), MADiE assigns the CMS eCQM identification to the new measure. The CMS eCQM ID is an essential data element when submitting eCQM data to CMS.

A CMS Electronic Health Record (EHR) Certification ID is a number generated by the Certified Health Information Technology (IT) Product List (CHPL) and used for reporting to CMS. It represents a single product or combination of products in the CHPL. The CMS EHR Certification ID is different from the CHPL product number. In the CHPL, this is the number generated when the hospital/clinician selects EHR Certification ID for a suite of products making up the hospital's/clinician's EHR solution. If a product changes, then a different CMS EHR Certification ID will be generated. The CMS EHR Certification ID is only unique to the product suite. If two different hospitals/clinicians happen to use the same products, then they will both have the same CMS EHR Certification ID.

CMS requires the CMS EHR Certification ID in several of its quality reporting programs. Check with individual quality reporting programs for requirements.

The CMS Measures Under Consideration Entry/Review Information Tool (CMS MERIT) is the web-based data collection portal allowing measure developers to submit candidate measures to CMS for consideration. The Tool walks the submitter through the process of providing information. Each submitter has a dashboard allowing them to track the progress of their submitted measure and to communicate with CMS through the comment function. The Tool also provides a view of all measures submitted for the current year. Another purpose of CMS MERIT is to give federal officials, the consensus-based entity multi-stakeholder groups, and other stakeholders more information as they review measures.

The CMS Measures Management System (MMS) Hub is a resource providing information about the MMS, guidance for measure developers (content previously found in the Blueprint), and quality measure-related news and events. It includes information on measure development, measure implementation, measure maintenance, tools, templates, opportunities to participate in public comment and technical expert panels, and more.

The CMS Quality Reporting Document Architecture (QRDA) Implementation Guides (IGs) are based on the Health Level Seven International® QRDA IGs. The CMS QRDA Category I IG is used for hospital CMS quality reporting programs. The CMS QRDA Category III IG is used for eligible clinician CMS quality reporting programs.

The CMS Quality Reporting Document Architecture (QRDA) Pre-Submission Validation Tools are resources offering QRDA validation tools available to submitters. The intent is to give users a single point of reference for these tools and assist them in selecting the most appropriate tool to meet their individual needs. The tools cover

• Cypress
• Hospital Quality Reporting System via Healthcare Quality Information System (HCQIS) Access Roles and Profile (HARP)

Code repositories are a file archive and web hosting facility providing secure storage for code and version control. 

A code system is a managed collection of concepts with each concept represented by at least one internally unique code and a human readable description, e.g., SNOMED CT.

A coding system is the symbolic arrangement of data or instructions in a computer program or the set of such instructions.

A comment period is the period of time the public has to respond to a request for public comment, such as a proposed rule, Request for Information, a new measure posted on the Measures Management System Hub, or some other document. The Administrative Procedure Act requires federal agencies to give the public an opportunity to participate in rulemaking. Executive Orders 12866 and 13563 provide guidance noting a comment period generally should be no less than 60 days, but the length of the comment period varies if not part of the rulemaking process.

A composite measure is a measure containing two or more individual measures, resulting in a single measure with a single score.
