Case Management Modeling and Notation (CMMN)

Case Management Modeling and Notation “is a graphical notation used for capturing work methods that are based on the handling of cases requiring various activities that may be performed in an unpredictable order in response to evolving situations.” Visual Paradigm. (n.d.). What is case management and modeling notation (CMMN). Retrieved September 13, 2023, from

Case presentation

A case presentation is a formal communication between health care professionals (e.g., physicians, pharmacists, nurses, therapists, nutritionists) that gives 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.

Change Review Process (CRP)

The Change Review Process (CRP) provides electronic clinical quality measure (eCQM) users the opportunity to review and comment on draft changes to the eCQM specifications and supporting resources under consideration by the measure steward. CMS conducts the CRP through the Office of the National Coordinator for Health Information Technology Project Tracking System (Jira) website. The goal of the CRP is for eCQM implementers to comment on the potential impact of changes to eCQMs so CMS and measure stewards can make improvements to meet CMS’s intent of minimizing provider and vendor burden in the collection, capture, calculation, and reporting of eCQMs. To participate in the CRP, users must have a Jira account and log into the eCQM Issue Tracker where the eCQM developer posts specific CRP tickets for public comment and voting. Users can sign up for an account on the login in page.

Clinical decision support (CDS)

Clinical decision support (CDS) is health information technology functionality that builds 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 (CDS) implementation activities

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).

Clinical decision support (CDS) alert fatigue

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.

Clinical decision support (CDS) alerts

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.

Clinical decision support (CDS) artifacts

Clinical decision support (CDS) artifacts are items representing medical knowledge from various knowledge sources (e.g., clinical guidelines, peer-reviewed articles, local best practices, and clinical quality measures). The artifacts can take many forms, but the goal is to create computable, interoperable translations using Clinical Quality Language. As of September 2023, there are 76 CDS artifacts found in the Repository. A variety of organizations, including federal agencies, contribute CDS artifacts to the Repository and they span a number of topics including anatomy, health care, and diseases.

Clinical decision support (CDS) developer

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 Document Architecture (CDA)

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. Wallask, S. (n.d.). Clinical document architecture (CDA). TechTarget: Health IT. Retrieved September 13, 2023, from

Clinical information systems (CIS)

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.

Clinical practice guidelines (CPG)

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.  

Clinical quality measure (CQM)

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 Consensus-Based Entity (CBE)

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 stakeholders to foster health care quality improvement.

CMS Data Element Library (DEL)

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.

CMS National Quality Strategy (NQS)

The CMS National Quality Strategy (NQS) is a long-term initiative with the aim to promote the highest quality outcomes and safest care for all individuals. The CMS NQS has four priority areas: Outcomes and Alignment, Equity and Engagement, Safety and Resiliency, and Interoperability and Scientific Advancement.

Comment period

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.

Communication or health communication activities

Communication activities are the study and use of communication strategies to inform and influence individual and community decisions affecting health. Health communications link the fields of communication and health and are increasingly recognized as necessary elements to improve personal and public health. Examples of communication activities include traditional (e.g., print through manuscripts, professional presentations, issue briefs, white papers, television, radio media) and non-traditional (e.g., social marketing techniques and social media platforms) methods of communication to present and disseminate information, such as clinical guidelines to encourage their use and adherence. For more information see Centers for Disease Control and Prevention's Gateway to Health Communication.
