Quality Data Model (QDM)v5.6 to QI-Core R5 Mapping

This page is part of the Quality Improvement Core Framework (v5.0.0: STU 5) based on FHIR R4. This is the current published version. For a full list of available versions, see the Directory of published versions.

Introduction

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 2024) and QDM’s complete history can be found on the eCQI Resource Center. Most of the QDM concepts map directly to US Core R5, 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 R5 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.

Change from QI-Core 4.1.1 to QI-Core 5.0.0

QI-Core builds upon US Core and new US Core STU5 profiles include a number of changes that impact expression of requests for information. These include new observation profiles, change to referencing conditions and diagnoses, and addition of a ServiceRequest profile. QI-Core addresses these changes as follows:

1.Condition

  • a. QICore Condition Problems and Health Concerns Profile – this is basically a name change from the previously defined QICore Condition profile
  • b. QICore Condition Encounter Diagnosis Profile – this new profile, based on US Core STU5 Condition Encounter Diagnosis Profile is based upon the core FHIR Condition Resource and meets the U.S. Core Data for Interoperability (USCDI) v2 ‘Encounter Diagnosis’ requirements. To promote interoperability and adoption through common implementation, this profile defines constraints and extensions on the Condition resource for the minimal set of data to record, search, and fetch information about an encounter diagnosis. It identifies which core elements, extensions, vocabularies and value sets SHALL be present in the resource when using this profile. It provides the floor for standards development for specific uses cases.

2.Observations

QI-Core 5.0.0 includes 22 profiles based on the FHIR Observation resource, some including specific QI-Core constraints added to the US Core profiles, others used as specified by US Core. QI-Core also continues to include a generic QICore Observation profile to address findings not included in the specific profiles. The following list should help determine which QI-Core observation profile to use with each QDM datatype. The subsequent mapping tables provide more detail about how to address these new profiles when converting measures from QDM to QI-Core.

3.ServiceRequest – QI-Core 5.0.0 ServiceRequest adds constraints to the US Core STU5 ServiceRequest rather than the base FHIR 4.0.1 ServiceRequest.

Adverse Event

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:

  • AdverseEvent.event = fall
  • AdverseEvent.resultingCondition = fracture
  • AdverseEvent.suspectEntity = area rug

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.

Allergy/Intolerance

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.

Assessment

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. In previous versions of QI-Core, QDM Assessment category mapped directly to QICore Observation. Changes in US Core STU5 include several new observation-type profiles such that there are now six profiles providing greater specificity in defining observations. QI-Core inherits four of the observation profiles directly from US Core as no additional constraints are necessary:

QI-Core includes a profile based on US Core Observation Survey to address additional constraints (Must Support elements), and QI-Core retains a generic Observation profile to allow measure and CDS expressions requiring data not covered by the more specific profiles:

  • QICore Observation Survey – generally used with for evaluation surveys and assessment tools
  • QICore Observation Profile – used only if the specific observation is not addressed by one of the more specific observation profiles; for example, gestational age at birth as a standalone observation (i.e., not part of a survey or assessment tool).

Assessment, Order

Assessment, Order uses the ServiceRequest resource. The codes for ordering specific observations should reference the code element specified in the respective profile: QICore Observation Survey; US Core Observation Sexual Orientation, US Core Observation Social History, US Core Observation SDOH Assessment, US Core Smoking Status Observation, or QICore Observation.

Care Experience

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’s “Care Experience” maps to either one of two QI-Core profiles, dependent on the type of information desired:

  • QICore Observation Survey Profile – generally used with for evaluation surveys and assessment tools; if the care experience information is obtained using a survey, the QICore Observation Survey Profile is appropriate.
  • QICore Observation Profile – If care experience is expressed as a single finding or observation, the QICore Observation profile is appropriate.

Patient Care Experience

Care Goal

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.

Communication

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.

FHIR Communication Resource

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.

HL7 FHIR Procedure Resource

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.

Diagnosis

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).

Based on changes in US Core STU5, QI-Core now has two methods for expressing conditions, QICore Condition Problems and Health Concerns Profile, and QICore Condition Encounter Diagnosis Profile. Please reference the respective profile pages for explanation of the rationale for using each of these profiles. Briefly, the Condition Problems and Health Concerns Profile meets the US Core Data for Interoperability (USCDI) version 2 ‘Problems’ and ‘Health Concerns’ and SDOH Problems/Health Concerns requirements. The Condition Encounter Diagnosis Profile further meets the USCDI v2 requirement to define Encounter Diagnosis.

Device

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”:

  • Devices that interact with the human body but do not stay in it are referred to as non-implantable medical devices.
  • Implantable devices are those which stay in the human body with a medical objective for an extended period of time, or even a lifetime.

[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.

Device, Applied

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.

Diagnostic Study

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.

QI-Core has added specific constraints on US Core STU5 additional profiles that address such non-laboratory tests:

  1. QICore Observation Clinical Test Result – non-laboratory, non-imaging tests; this profile is sufficiently broad that it should be used instead of the QI-Core Observation profile for all non-laboratory, non-imaging test results
  2. QICore Observation Imaging Result – imaging study results

Diagnostic Study, Order

“Diagnostic Study, Order” should reference orders for studies that will generate results for activities that meet criteria for Observation Clinical Test or Observation Imaging Result profiles.

Diagnostic Study, Performed

Individual studies may use the US Core DiagnosticReport Profile for Report and Note Exchange 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 QICore Observation Clinical Test Result or the QICore Observation Imaging Result 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 such LOINC codes to specify the type of testing considered acceptable to provide sufficient fidelity to their requests.

Encounter

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.

Encounter Timing

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.

Immunization

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.

Individual Characteristics

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:

  • Clinical Trial – Patients may be excluded from some quality measures or clinical decision support (CDS) workflows if they are participating in clinical trials. It is often necessary to determine the nature of the trial as exclusions may only apply if the clinical trial addresses the same clinical condition as the measure or CDS artifact, or if treatments potentially used in the clinical trial or the measure or CDS intervention conflict.

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.

Intervention

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.

Procedure Vs Intervention

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.

QI-Core references procedure.priority based on the relationship of the procedure to the Encounter; hence, Encounter.procedure (which is an extension).

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.

Laboratory Test

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.

Rather than directly referencing the US Core Laboratory Result Observation Profile, QI-Core 5.0.0 builds on that profile to add further constraint requirements as QICore Laboratory Result Observation. The reason for this approach is to assure Must Support elements for the interpretation element, specific result datatypes, and specific references.

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 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.

Laboratory Test, Order

“Laboratory Test, Order” should reference orders for studies that will generate results for activities that meet criteria for Observation Lab Result.

Medication

QDM defines Medication as clinical drugs or chemical substances intended for use in the medical diagnosis, cure, treatment, or prevention of disease. Medications are defined as direct referenced values or value sets containing values derived from code systems such as RxNorm. QDM defines five contexts for Medication, each of which is listed below referencing the US Core or FHIR resource which provides the expected context:

Medication, Active

This QDM context correlates with a medication on a patient’s active medication list. In QI-Core STU3, Medication, Active was mapped to MedicationStatement. However, consistent with US Core R4 Update, medication list should use MedicationRequest and not MedicationStatement. The mapping table provides guidance about how to use MedicationRequest.requester to specify medications ordered directly, those reported by a physician and those reported by the patient for a medication list.

The MedicationRequest SHALL include all prescribed and “self-prescribed” medications reported by the Provider, Patient or Related Person.

  • SHALL use reported[x] to indicate the MedicationRequest record was captured as a secondary “reported” record rather than an original primary source-of-truth record. It may also indicate the source of the report
  • When recording “self-prescribed” medications SHALL use intent = “plan”
  • When recording “self-prescribed” orders, SHOULD use the requester to indicate the Patient or RelatedPerson as the prescriber

Medication, Administered

This QDM context correlates with a record of a patient consuming or otherwise being administered a medication. It references individual medication administration events and, therefore, may not reference frequency of administration. Note that a separate QDM and US Core profile address Immunization, Administered.

This QDM context specifically references the discharge medication list provided to a patient at the time of discharge from an inpatient setting. The list may include reference to new prescriptions sent to a pharmacy for dispensing and self-administration after discharge. It may also include over-the-counter medications and those medications already present in the patient’s home for which new prescriptions are not necessary.  The QDM Medication, Discharge concept is mapped to MedicationRequest as a request to the patient to take the medication with MedicationRequest.intent = plan and MedicationRequest.setting = discharge.

MedicationRequest.intent should always be order even if the medication is patient reported and the order is not processed as an e-prescription. The reporter is specified as MedicationRequest.reported[x] which is a reportedBoolean and uses reportedReference (patient, practitioner, practitionerRole, relatedPerson, organization).

This change should also be used to reference the mapping from QDM Medication, Order which can address order or recommended.

Negation Rationale for Medication, Dispensed

Use QICoreMedicationDispenseNotDone, which contains:

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.

Medication, Order

This QDM context references the QI-Core MedicationRequest resource with MedicationRequest.intent = order and MedicationRequest.setting as the most appropriate for the intended meaning of the quality measure or clinical decision support (CDS) expression.

Physical Exam

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 STU5 added twelve observation profiles that address specific elements of physical examinations. The previous version inherited the FHIR Vital Signs Profile; in version STU5, US Core created specific profiles for each of those vital sign elements, resulting in a Vital Signs Profile with 12 component profiles that meet the definition of QDM “Physical Examination”. The following table lists each profile and the respective data element codes referenced in each of those profiles.

Procedure

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.

Procedure Vs Intervention

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.

Procedure Vs Task

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:

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:

  • Task.status with valueset-task-status constrained to “rejected” (The potential performer who claimed ownership of the task has decided not to execute it prior to performing any action.)
  • Task.statusReason binding to Negation Reason Codes (extensible)
  • Task.code (Codes to identify how the task manages fulfillment of activities - the specific choice depends on the measure context) the direct reference code, it needs a cardinality of 1..1 and binding to the code or value set (it would need a notDoneValueSet URL: notDoneValueSet to reference the value set not performed
  • Task.focus to reference the Resource (likely procedure) the task was acting on
  • Task.encounter (Healthcare event during which this task originated)
  • Task.for (Beneficiary of the Task) Reference (qicore-patient)
  • Task.executionPeriod for the period/dateTime - the timing the task was rejected and the reason.

Procedure Priority

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.

Substance

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::

  • Determination that blood products (a biological product in FHIR resources) are ordered or are administered within specific time relationships to other data elements – The FHIR Resource, BiologicallyDerivedProduct, possibly using Procedure and ServiceRequest might have promise. However, the resource is still in development. Therefore, until further information is available, rather than expressing the QDM datatype Substance, Administration to address administration of blood transfusion, quality measure and clinical decision support (CDS) authors should consider using the procedure resource with a code representing transfusion.
  • Determination that human breast milk is used exclusively to feed newborn infants during the initial stay in the hospital after birth – Currently, FHIR includes a NutritionOrder resource to reference a request for a specific diet, or supplements to a diet. However, a resource for documenting administration of nutrition-related substances is still in development. Therefore, for this use case a quality measure or a clinical decision support (CDS) author could reference a NutritionOrder for an exclusive breast milk diet for the infant; however, such an expression could not reference clinical intake and output records to determine if anything other than human breast milk was administered to the infant. Moreover, classification of human breast milk requires clarification as to whether it is a BiologicallyDerivedProduct, or if it should be referenced as a Substance.

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.

Symptom

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.
