QI-Core Implementation Guide
4.1.0 - release
This page is part of the Quality Improvement Core Framework (v4.1.0: STU 4) based on FHIR R4. The current version which supercedes this version is 4.1.1. For a full list of available versions, see the Directory of published versions 
The CMS Quality Data Model (QDM) has been used to express electronic clinical quality measures (eCQMs) in HQMF since 2012. QDM is a conceptual data model that has evolved based on feedback, testing and use. The current version (Version 5.6 for eCQM implementation 2023) and QDM’s complete history can be found on the eCQI Resource Center. Most of the QDM concepts map directly to US Core R4, FHIR R4 resources or extensions represented in QI-Core.
This version of QI Core updates mappings from QI-Core to QDM based on US Core R4 and FHIR R4 and QDM version 5.6. Reviewers can evaluate the comparisons, represented in the Mappings table for each QI-Core resource. Each mapping table shows the QI-Core concept in the left-hand column and the corresponding QDM datatype(s) and attributes in the left-hand column. Only QI-Core metadata concepts represented in QDM are included in the mapping tables. The effort mapped the intended meaning of each QDM datatype and attribute to a QI-Core resource metadata element. In some cases, multiple QDM datatypes map to a single QI-Core resource as indicated in the QI-Core mapping table.
In addition to the QI-Core to QDM comparisons presented with each QI-Core resource, this section of the implementation guide presents the mapping directly from QDM concepts. Thus, the IG provides a view of the mappings in both directions (QI-Core to QDM, and QDM to QI-Core). This section is divided into 55 sections, one for each QDM concept, or QDM datatype. Each QDM datatype includes a general description of the concept and a table mapping each of the QDM datatype-related attributes to QI-Core metadata elements. Refer to the eCQI Resource Center for the full QDM 5.6 documentation.
This QDM to QI-Core Mapping for the QDM Datatype “Adverse Event” has been updated from QDM 5.5 to QDM 5.6.
QDM defines Adverse Event as any untoward medical occurrence associated with the clinical care delivery, whether or not considered drug related. The concepts aligns with the FHIR R4 resource Adverse Event (http://hl7.org/fhir/adverseevent-definitions.html#AdverseEvent). The FHIR resource provides clearer expressivity as compared with QDM.
QDM includes an attribute code that represents the specific type of event that occurred, consistent with AdverseEvent.event.
QDM does not include an attribute to address the additional elements available in QI-Core: AdverseEvent.suspectEntity (the suspected cause), or the AdverseEvent.resultingCondition. As an example to differentiate these elements:
QDM version 5.6 (and earlier versions) only address one of these elements, the event. Therefore, QDM AdverseEvent code maps to AdverseEvent.event. Measure developers seeking to retrieve data about the cause of an AdverseEvent may be able to relate the occurrence timing of a potential causative event and the AdverseEvent.event timing. Further detail about the AdverseEvent will require use of FHIR or potentially a subsequent version of QDM after QDM 5.6.

This QDM to QI-Core Mapping for the QDM Datatype “Allergy/Intolerance” is updated from QDM 5.5 to QDM 5.6
Allergy is used to address immune-mediated reactions to a substance such as type 1 hypersensitivity reactions, other allergy-like reactions, including pseudo-allergy.
Intolerance is a record of a clinical assessment of a propensity, or a potential risk to an individual, to have a non-immune mediated adverse reaction on future exposure to the specified substance, or class of substance.

QDM defines Assessment as a resource used to define specific observations that clinicians use to guide treatment of the patient. An assessment can be a single question, or observable entity with an expected response, an organized collection of questions intended to solicit information from patients, providers or other individuals, or a single observable entity that is part of such a collection of questions.
Assessment, Performed uses the Observation resource. However, specifically for evaluating smoking status, use the specific QI-Core smoking status assessment profile inherited from US Core.

QDM defines Care Experience as the experience a patient has when receiving care or a provider has when providing care. QDM represents two kinds of care experience: Patient Care Experience and Provider Care Experience. While generally interpreted as patient or provider satisfaction, experience may also represent understanding, involvement and other factors about the care received or given. Most often organizations obtain such information using questionnaires. Use cases are welcome to help provide examples for us of this concept. The Care Experience concept best fits with the FHIR Observation resource.

QDM defines Care Goal as a defined target or measure to be achieved in the process of patient care, that is, an expected outcome. A typical goal is expressed as a change in status expected at a defined future time. That change can be an observation represented by other QDM categories (diagnostic tests, laboratory tests, symptoms, etc.) scheduled for some time in the future and with a particular value. A goal can be found in the plan of care (care plan), the structure used by many stakeholders to define the management actions for the various conditions, problems, or issues identified for the target of the plan. This structure, through which the goals and care-planning actions and processes can be organized, planned, communicated, and checked for completion, is represented in QDM as a Record Artifact in which Care Goal is found.

QDM defines Communication as the transmission, receipt, or acknowledgement of information sent from a source to a recipient, such as from one clinician to another regarding findings, assessments, plans of care, consultative advice, instructions, educational resources, etc. The following text from the FHIR Communication and Procedure Resources may help to differentiate when to use Communication.
This resource is a record of a communication. A communication is a conveyance of information from one entity, a sender, to another entity, a receiver. The sender and receivers may be patients, practitioners, related persons, organizations, or devices. Communication use cases include:
A reminder or alert delivered to a responsible provider
A recorded notification from the nurse to the on-call physician (or any other specified person) that a patient’s temperature exceeds a value
A notification to a public health agency of a patient presenting with a communicable disease reportable to the public health agency
Patient educational material sent by a provider to a patient
Unable to deliver lab results to ordering physician
Non-patient specific communication use cases may include:
A nurse call from a hall bathroom
Advisory for battery service from a pump
Boundaries and Relationships (Section 8.20.2) - Communication and Encounter
The Communication is about the transfer of information (which might or might not occur as part of an encounter), while Encounter is about the coming together (in person or virtually) of a Patient with a Practitioner. Communication does not deal with the duration of a call, it represents the fact that information was transferred at a particular point in time.
The phone calls involving the Patient should be handled using Encounter. Phone calls not involving the patient (e.g. between practitioners or practitioner to relative) that are tracked for billing or other purposes can use Communication to represent the information transferred but are not ideal to represent the call itself. A better mechanism for handling such calls will be explored in a future release.
The boundary between determining whether an action is a Procedure (training or counseling) as opposed to a Communication is based on whether there’s a specific intent to change the mind-set of the patient. Mere disclosure of information would be considered a Communication. A process that involves verification of the patient’s comprehension or to change the patient’s mental state would be a Procedure.

QDM defines Condition/Diagnosis/Problem as a practitioner’s identification of a patient’s disease, illness, injury, or condition. This category contains a single datatype to represent all of these concepts: Diagnosis. A practitioner determines the diagnosis by means of examination, diagnostic test results, patient history, and/or family history. Diagnoses are usually considered unfavorable, but they may also represent neutral or favorable conditions that affect a patient’s plan of care (e.g., pregnancy).

QDM defines Device as an instrument, apparatus, implement, machine, contrivance, implant, in-vitro reagent, or other similar or related article, including a component part or accessory, intended for use in the diagnosis, cure, mitigation, treatment, or prevention of disease and not dependent on being metabolized to achieve any of its primary intended purposes.
FHIR defines the Device Resource as a type of a manufactured item that is used in the provision of healthcare without being substantially changed through that activity. The device may be a medical or non-medical device.
FHIR and US Core further differentiate devices into two “classes”:
[Definition reference: Imam W. How to use ISO 13485:2016 to manage implantable devices, ISO 13485 Blog. July 4, 2016. Available at: https://advisera.com/13485academy/blog/2017/07/04/how-to-use-iso-134852016-to-manage-implantable-medical-devices/. Accessed 28 January 2020.]
The FHIR Device Resource addresses both implantable and non-implantable devices. US Core only references Implantable Device. QI-Core inherits Implantable Device from US Core and builds directly from FHIR for the QI-Core Device Resource.
QDM originally designed Device, Applied to allow access to documentation of device usage. However, evaluation over time indicates that all documentation about usage of a device occurs as an observation. Thus, information about an implanted pacemaker status check, utilization of a patient-use Continuous Positive Airway Pressure (CPAP) device, results from a glucometer, or use of a wheelchair or cane should use the QDM datatype, Assessment, Performed, or QI-Core Observation. Use of Device, Applied has been synonymous with Procedure, Performed, i.e., placement of or adjustment to a device.
“Device Applied” has been retired in QDM 5.6 in favor of using “Procedure, Performed” or “Assessment, Performed” as appropriate.

QDM defines Diagnostic Study as any kind of medical test performed as a specific test or series of steps to aid in diagnosing or detecting disease (e.g., to establish a diagnosis, measure the progress or recovery from disease, confirm that a person is free from disease). The QDM differentiates diagnostic studies from laboratory tests in that diagnostic studies are those that are not performed in organizations that perform testing on samples of human blood, tissue, or other substance from the body. Diagnostic studies may make use of digital images and textual reports. Such studies include but are not limited to imaging studies, cardiology studies (electrocardiogram, treadmill stress testing), pulmonary-function testing, vascular laboratory testing, and others.
Thus far, consensus opinion suggests that the FHIR Observation Resource best fits the diagnostic study use case for querying clinical data to retrieve information about the event and/or the result of the study. Individual studies may use the US Core DiagnosticReport-note (http://hl7.org/fhir/us/core/StructureDefinition-us-core-diagnosticreport-note.html) to provide information about an individual study (e.g., a cardiac ultrasound, MRI, etc.) although some have considered use of other reporting resources and artifacts. Since new studies regularly become available and the nature of existing studies change over time, a complete list of studies to reference a desired result cannot be assured. Therefore, a quality measure or clinical decision support (CDS) artifacts seeking a specific result value should use the Observation resource to request a retrieve of the result value desired. This practice will enable implementers to determine which is the best source for the desired observation. LOINC observable entities may indicate specific methods for determination of results. Measure and CDS developers can reference direct reference codes or value sets using the such LOINC codes to specify the type of testing considered acceptable to provide sufficient fidelity to their requests.

QDM defines Encounter as an identifiable grouping of healthcare-related activities characterized by the entity relationship between the subject of care and a healthcare provider; such a grouping is determined by the healthcare provider. A patient encounter represents interaction between a healthcare provider and a patient with a face-to-face patient visit to a clinician’s office, or any electronically remote interaction with a clinician for any form of diagnostic treatment or therapeutic event.
Implementation considerations must be considered when referencing encounter periods (start to end time). Some clinical sites may leave Encounters “open” until all documentation has been completed which may take 72 hours or more. However, the actual encounter may have lasted for a much shorter time period (e.g., 15 minutes for an ambulatory encounter). This issue is addressed in The Office of the National Coordinator for Health IT (ONC) Issue Tracking System as item QDM-235. Two approaches clinical sites have used to manage this issue include:
Include a patient check-in and check-out time as part of the visit documentation. These times represent when the patient arrives and leaves, respectively, and these times are used for the Encounter relevant period. However, patient arrival at a location does not necessarily mean the start of the encounter (e.g. a patient arrives an hour earlier than he or she is actually seen by a practitioner).
Default an Encounter end as 23:59 on the date of the Encounter date if it is left open to allow completion of documentation and update the end time if the practitioner closing the chart enters a specific time that the encounter ended.
Undoubtedly, other clinical sites have implemented other solutions to documenting end times for ambulatory visits. Quality measure and clinical decision support (CDS) artifact authors should consider such issues when testing the validity and reliability of retrieved responses to data queries.
Encounter.diagnosis refers to the list of diagnosis/diagnoses relevant to the encounter. The Encounter.diagnosis.use value differentiates if the diagnosis is the admission diagnosis (AD), the discharge diagnosis (DD), the chief complaint (CC), a comorbidity diagnosis (CM), a pre-op diagnosis (pre-op), a post-op diagnosis (post-op) or a billing diagnosis (billing).
Some quality measures used to evaluate care provided in hospital settings use concepts to define principal diagnosis and present on admission:
Principal diagnosis is defined as the condition that, after study, was determined to be the principal cause of the admission. QDM version 5.5 addresses that concept using the US Core concepts Encounter.diagnosis.use value=billing with an diagnosis.rank=1.
Present on admission (POA) is an indicator assigned to Inpatient Encounter diagnoses and is used in quality and patient safety measures. QDM version 5.5 references this indicator as a component of each Encounter, Performed diagnosis The US Core and FHIR Encounter resources do not address present on admission. However, the FHIR Claim resource includes a claim.diagnosis.onAdmission element referencing similar terms as the US UB-04 claim form to indicate present on admission – yes (y), no (n), unknown (u), and undetermined (w). QI-Core includes an extension on Encounter.diagnosis to reference the onAdmission element, thus enabling specification of an Encounter.diagnosis that is present on admission.
Principal procedure is the procedure performed for definitive
treatment rather than diagnostic or exploratory purposes, or which
is necessary to take care of a complication.
[https://manual.jointcommission.org/releases/TJC2015B/DataElem0685.html] Principal procedure defines a procedures relationship to an encounter
(most often an inpatient encounter). It has not relationship to the
inherent nature of the procedure. Therefore, QI-Core includes an
extension modeling Encounter.procedure in the same way as
Encounter.diagnosis. The Encounter.procedure has a code to indicate
the procedure code and a rank to indicate its ordinality such that
rank=1 identifies the procedure as a principal procedure.
Elective procedure is another concept used in quality measurement, especially in hospital measures. A specific measure may have interest in evaluating care provided for elective procedures (e.g., hip surgery due to osteoarthritis) while excluding emergency, non-planned procedures (e.g., hip surgery due to acute fracture). The procedure code does not necessarily allow differentiation of the two concepts. A ServiceRequest.priority does have the ability to differentiate the urgency with which the request (or order) should be fulfilled. However, there is no element within the FHIR Procedure resource to address the issue. Encounter.priority allows specification of whether the encounter is elective. Since the Encounter.procedure can be linked to the ServiceRequest with its priority, there is no need to add a specific extension in QI-Core for Encounter.procedure.priority. Therefore, there is no direct mapping from the QDM Procedure priority attribute to QI-Core and measures considering the concept should reference QDM’s Encounter, Order with its priority.

QDM defines Immunization as vaccines administered to patients in healthcare settings but does not include non-vaccine agents. The FHIR Immunization Recommendation resource is specifically designed to provide an immunization forecast from a forecasting engine to a provider, basically to carry clinical decision support recommendations specific to immunizations and, therefore, is not consistent with the intent of the QDM datatype “Immunization, Order” or “Immunization, Administered.” The FHIR Immunization Evaluation references an appraisal of an immunization that was administered to determine if it is valid with respect to the expected immunization schedule. The US Core Immunization profile is most consistent with the QDM datatype Immunization, Administered. The mapping tables provided include mapping from QDM Immunization, Administered and a reference to the FHIR Immunization Evaluation resource. Note, the mapping table includes additional metadata about immunizations that QDM does not address, but that may be relevant to quality measures or clinical decision support (CDS) artifacts.

QDM’s approach to defining information about participants In the healthcare process by defining Individual Characteristics. These properties of a patient, clinician, provider, or facility include demographics, behavioral factors, social or cultural factors, available resources, and preferences. Behaviors reference responses or actions that affect (either positively or negatively) health or healthcare. Included in this category are mental health issues, adherence issues unrelated to other factors or resources, coping ability, grief issues, and substance use/abuse. Social/cultural factors are characteristics of an individual related to family/caregiver support, education, and literacy (including health literacy), primary language, cultural beliefs (including health beliefs), persistent life stressors, spiritual and religious beliefs, immigration status, and history of abuse or neglect. Resources are means available to a patient to meet health and healthcare needs, which might include caregiver support, insurance coverage, financial resources, and community resources to which the patient is already connected and from which the patient is receiving benefit. Preferences are choices made by patients and their caregivers relative to options for care or treatment (including scheduling, care experience, and meeting of personal health goals) and the sharing and disclosure of their health information.
FHIR more effectively represents these concepts in the Level 3 Administration Module – base data that is linked into other modules for clinical content, finance/billing, workflow, etc. The Administration Module specifies information about the patient, related person, practitioner and organization that is the basis of healthcare-related interactions such as encounters. QDM version 5.5 adopted a similar approach to such information by adding a new concept called Entities. Entities represent concepts that can be used to specify details about an actor (or performer) participant in any activity represented by a QDM datatype. These entities are analogous to the FHIR resources Patient, RelatedPerson, Practitioner, and Organization, respectively called Patient, CarePartner, Practitioner and Organization in QDM. The mapping tables show these direct relationships to FHIR resources. However, to maintain backward compatibility with prior QDM versions, QDM 5.5 retains the concept of Patient Characteristics for some metadata about a patient; most of these characteristics map directly to metadata elements in the FHIR Patient resource. QDM 5.5 removed the Provider Characteristics QDM datatype in favor of the Practitioner and Organization entities since there had been little, if any, use of these QDM elements.
Accommodating patient-related metadata requires QI-Core extensions for several elements including:
QDM 5.5 also added a new QDM datatype Related Person to allow reference to an individual who has a personal or non-healthcare-specific professional relationship with a patient. Modeled the same as the CarePartner entity, the Related Person is an individual from whose record clinical information should be retrieved to support care provided to the index patient.
Example 1: An infant’s gestational age at the time of birth may be calculated as the difference between the days between the mother’s estimated date of delivery (EDD) and the actual birth date. The mother’s EDD might be entered directly on the infant’s record as an observable entity about a Related Person (the infant’s mother). Alternatively, a cross-context query might request the information from the Related Person’s (mother’s) record.
Example 2: An organ recipient risk factor may include a donor’s positive Hepatitis C antibody result. The result relates to the donor (Related Person) whether that result is present on the recipient’s record or if the a cross-context query to the donor’s record retrieves the information.

QDM defines Intervention as a course of action intended to achieve a result in the care of persons with health problems that does not involve direct physical contact with a patient. Examples include patient education and therapeutic communication.
FHIR references both of these concepts using the Procedure resource, specifically noting a process that involves verification of the patient’s comprehension or to change the patient’s mental state would be a Procedure. Therefore, both QDM datatypes, Procedure and Intervention are included in this section of the QDM to QI-Core mapping especially since all of the QDM attributes for each of these QDM datatypes are identical.

QDM defines Laboratory Test as a medical procedure that involves testing a sample of blood, urine, or other body fluids or specimens. Tests can help determine a diagnosis, plan treatment, check to see if treatment is working, or monitor the disease over time. This QDM data category for Laboratory Test is only used for information about the subject of record.
Thus far, consensus opinion suggests that the US Core Observation-Lab Profile best fits the laboratory test use case for querying clinical data to retrieve information about the event and/or the result of the study. Individual studies may use the US Core DiagnosticReport-lab (http://hl7.org/fhir/us/core/StructureDefinition-us-core-diagnosticreport-lab.html) to provide information about an individual laboratory test although some have considered use of other reporting resources and artifacts. Each laboratory test may be ordered individually or in a panel. Many use panels for convenience for ordering laboratory tests. Since new laboratory panels regularly become available and the myriad of potential laboratory panels available, a complete list cannot be assured. Therefore, a quality measure or clinical decision support (CDS) artifacts seeking a specific result value should use the US Core Observation-Lab profile to request a retrieve of the result value desired. This practice will enable implementers to determine which is the best source for the desired observation. LOINC observable entities may indicate specific methods for determination of results. Measure and CDS developers can reference direct reference codes or value sets using the such LOINC codes to specify the type of testing considered acceptable to provide sufficient fidelity to their requests.

The MedicationDispensed.status is fixed to “declined” which is defined as “The dispense was declined and not performed.” Considering the clinical workflow, only the pharmacist likely performs the “decline” status - based on medication interaction or on failure of insurance authorization (perhaps due to patient declining when the cost/co-pay is identified). But the patient would not enter the status, only the pharmacist would do so. The use case likely still works for the measure developer intent (that a valid reason exists for not dispensing the medication). However, if the measure developer wants to address patient’s decisions to avoid dispensing, the patient will likely not show up at the pharmacy for the medication to be dispensed - hence, there will be no dispensing event. The best way to capture that scenario may be to assure the MedicationRequest includes a Patient reason.

QDM defines Physical Exam as the evaluation of the patient’s body and/or mental status exam to determine its state of health. The techniques of examination can include palpation (feeling with the hands or fingers), percussion (tapping with the fingers), auscultation (listening), visual inspection or observation, inquisition and smell. Measurements may include vital signs (blood pressure, pulse, respiration) as well as other clinical measures (such as expiratory flow rate and size of lesion). Physical exam includes psychiatric examinations.
US Core defines a resources for vital signs (referencing the FHIR Vital Signs Profile) and three additional profiles – Pediatric-BMI-for Age, Pediatric Weight for Height and Pulse Oximetry. Other observations that meet the QDM definition of Physical Exam, Performed use the FHIR Observation resource.

QDM defines Procedure as an act whose immediate and primary outcome (post-condition) is the alteration of the physical condition of the subject. A procedure may be a surgery or other type of physical manipulation of a person’s body in whole or in part for purposes of making observations and diagnoses or providing treatment.
FHIR references both of these concepts using the Procedure resource, specifically noting a process that involves verification of the patient’s comprehension or to change the patient’s mental state would be a Procedure.
Some use cases have considered differentiating a FHIR Procedure Resource from a FHIR core Task Resource. For example, should a request to perform medication reconciliation be classified as a Task or a Procedure? The FHIR Procedure Resource Boundaries and Relationships (Section 9.3.2) provides some distinction between a Task and a Procedure:
A Task is a workflow step such as cancelling an order, fulfilling an order, signing an order, merging a set of records, admitting a patient. Procedures are actions that are intended to result in a physical or mental change to or for the subject (e.g. surgery, physiotherapy, training, counseling). A Task resource often exists in parallel with clinical resources. For example, a Task might request fulfillment of a ServiceRequest ordering a Procedure.
Based on the guidance provided above, the workflow step to reconcile medication lists may be considered a Task to perform the Procedure that includes reviewing the medication list with the patient to assure it is correct and to education the patient about proper medication usage.
The sponsoring work group is specifically seeking feedback on the following suggestions for use of Task rather than Procedure for workflow steps that require attestation such as medication list review or reconciliation: Example: A workflow step to review or to reconcile medication lists may be considered a Task to perform the Procedure that includes reviewing the medication list with the patient to assure it is correct and to educate the patient about proper medication usage. Thus, a Task can reference the Task.focus as a procedure.
QDM 5.6 does not address Task; therefore, there is no direct mapping from QDM Intervention or Procedure to the FHIR Task resource. The mapping presented is from QDM to QI-Core referencing the FHIR Procedure resource.
Consistent with the method for specifying QDM’s concept negation rationale, a TaskNotDone is represented with the following content:
QDM 5.6 includes a new attribute for Procedure: priority with the following definition:
Priority indicates the urgency of the procedure or the encounter referenced. In [electronic clinical quality measures] (eCQMs) the priority attribute will help specify elective from urgent encounters (e.g., hospital admissions) or procedures. Priority is a codeable concept (i.e., may use a direct reference code or a value set). For example, priority is used to express an elective procedure or encounter from an emergency procedure or encounter.
As noted in the QDM to QI-Core Mapping for Encounter-Related Diagnoses and Procedures, a specific measure may have interest in evaluating care provided for elective procedures (e.g., hip surgery due to osteoarthritis) while excluding emergency, non-planned procedures (e.g., hip surgery due to acute fracture). The procedure code does not necessarily allow differentiation of the two concepts. A ServiceRequest.priority does have the ability to differentiate the urgency with which the request (or order) should be fulfilled. However, there is no element within the FHIR Procedure resource to address the issue. Encounter.priority allows specification of whether the encounter is elective. An encounter with Encounter.priority = elective and an Encounter.extension.extension:rank.value[x] = 1 addresses the need to specify an elective encounter with a principal procedure. Therefore, based on the current use case QI-Core has not added an extension to address Procedure.priority and, as a result, there is no direct mapping from the QDM Procedure priority attribute to QI-Core.

The elective nature of a procedure can also be referenced based on the elective nature of an Encounter (Encounter.priority) for which the respective procedure is a principal procedure. The concept may also be addressed as an Encounter, Order or Procedure, Order (both using ServiceRequest) and ServiceRequest.priority. |

Therefore, the procedure resource does not have a reference to author dateTime. Author dateTime can reference a report about the procedure or an observation describing that result (e.g., Observation with metadata Observation.partOf procedure). However, Procedure.statusReason needs to address a dateTime that it is recorded. |

QDM defines Substance as a homogeneous material with definite composition that includes allergens, biological materials, chemicals, foods, drugs and materials. QDM distinguishes between medications from non-medication substances by separately listing medication datatypes. Substance may or may not have a code or be classified by a code system such RxNorm. Examples of a substance may include environmental agents (e.g., pollen, dust) and food (e.g., vitamins). Where a substance can be addressed using medication terminology (e.g. egg albumin) used the Medication mappings listed in this QDM-to-QI-Core section.
FHIR defines substance as a homogeneous material with a definite composition. Medications are classified as substances. However, to reference other substances, especially using the SubstanceDefinition resource is challenging since the resource is still undergoing development.
Ideally, use of a substance-related resource should be driven by use cases and examples. Two such use cases currently exist in the quality measure community::
To provide some context and guidance, this QDM-to-QI-Core mapping includes reference to the QDM datatypes Substance, Order and Substance, Recommended using the NutritionOrder resource. As noted in the second example provided, the resource is relatively new and it allows expressions to address only the type of diet ordered, not the foods or substances administered to a patient.
The CQI Workgroup suggests use of the Procedure resource for QDM’s Substance, Administered for nutritional and other non-medication substances. Indicate the procedure (e.g., oral feeding) and the Procedure.UsedCode to indicate the direct reference code or value set indicating the expected nutritional element expected. There is no current known eCQM use case or common practice for documenting NutritionOrder “negation rationale”. Further, the only expressed use cases for substance other than those that are modeled similar to medications are nutritional substance administered (human breast milk) and biologically-derived product administration (blood) - both of these use cases can use the Procedure resources as noted. Further work in base FHIR will advise how to reference specific administration details in QI-Core.

QDM defines Symptom as an indication that a person has a condition or disease. Some examples include headache, fever, fatigue, nausea, vomiting, and pain. Symptoms are subjective manifestations of the disease perceived by the patient. As an example to differentiate symptom from finding, the patient’s subjective symptom of fever is distinguished from the temperature (a finding). For a finding, there is either a source of a temperature-measuring device together with a recorder of the device (electronically) or an individual (healthcare provider, patient, etc.).
Note: Definitions regarding symptom on the FHIR condition resource Boundaries and Relationships (Section 9.2.2: http://hl7.org/fhir/condition.html):
[The Condition] resource is not typically used to record information about subjective and objective information that might lead to the recording of a Condition resource. Such signs and symptoms are typically captured using the Observation resource; although in some cases a persistent symptom, e.g. fever, headache may be captured as a condition before a definitive diagnosis can be discerned by a clinician. By contrast, headache may be captured as an Observation when it contributes to the establishment of a meningitis Condition.
Use the Observation resource when a symptom is resolved without long term management, tracking, or when a symptom contributes to the establishment of a condition.
Use Condition when a symptom requires long term management, tracking, or is used as a proxy for a diagnosis or problem that is not yet determined.
Based on the FHIR referenced provided above, the QDM datatype Symptom maps to the FHIR Observation resource.
