About the IHE Buyers’ Guide

IHE (Integrating the Healthcare Enterprise) does a great job of defining solutions that use best practices to address important use cases. Integration profiles define which actors must perform which transactions. Actor names are intentionally generic—such as Image Display or Image Manager/Archive, instead of common product names like PACS or RIS—so that the capability described can be claimed by a multitude of products (for example, a VNA).

The challenge for buyers is understanding which specific integration profiles and actor combinations are important for commercial products. Because of this confusion, buyers often ask vendors about support for integration profiles and actors within their products, that may not be necessary to achieve the buyer’s clinical and technical goals.

The IHE Buyers’ Guide tool allows the user to select one or more commercial products—PACS, VNA, RIS, and/or Enterprise Viewer—and it will produce a “heat map”, showing the most important integration profiles and actors from the IHE Radiology (RAD) and/or the IHE IT Infrastructure (ITI) domains.

Interactive Guide to IHE

Integration profile and actor combinations are rated as Very Important (red), Somewhat Important (orange), Not Important (yellow) or Not Applicable (grey).

Criteria for Integration Profile Inclusion in the IHE Buyers’ Guide

The tool is designed for use by buyers when procuring a system. It includes integration profiles that are stable and final (status of Final Text), and where there is some evidence that commercial products that support the integration profile are available on the market, or will be available very soon. If there is no commercial system available that supports an integration profile, including it as a requirement in an RFP is of low value.

IHE Buyers Guide Updates for 2016-2017

The following changes were made:

  • 2017: Digital Breast Tomosynthesis Extension (DBT Extension) integration profile was added to the tool for Enterprise Viewer, PACS, and VNA products.
  • 2016: Imaging Object Change Management (IOCM) integration profile was added as it is now in Final Text and there are products available on the market that support this profile.
  • 2016: The priority of the Image Manager/Archive actor for PACS and VNA for Radiation Exposure Monitoring (REM) was raised from Somewhat Important to Very Important to reflect buyers’ priorities.

Preview of IHE Integration Profiles Pending the IHE Buyers Guide

The following IHE integration profiles are not in a status of Final Text, so have not been added to the IHE Buyers’ Guide yet. The expected importance of each profile/actor combination for each product type is provided, as a preview. Integration Profiles are organized under their IHE Domain.

Priority (P) Legend:

IHE - Very ImportantVery Important

IHE - ImportantSomewhat Important

IHE - Not ImportantNot Important

Radiology (RAD) Domain

Scheduled Workflow (SWF.b)

This revision to SWF is in Trial Implementation. It is revised to require Actors to support HL7 v2.5 within relevant transactions. The importance for each actor within each product type specified in the IHE Buyers Guide remains the same, however.

Scheduled Workflow (SWF) with CP-222

This revision to SWF is in Final Text and the changes specified by CP-222 have been incorporated into the IHE Technical Framework Revision 14. It added several valuable attributes to existing transactions to make data values fully qualified and easier to transfer across enterprises. These attributes include Issuer of Accession Number and Institution Name and Institution Code Sequence. It also makes Issuer of Patient ID available in many transactions, such as Query Modality Worklist. The importance for each actor within each product type specified in the IHE Buyers’ Guide remains the same, however.

Mobile Access to Health Document for Imaging (MHD-I)

MHD-I is an extension to the ITI MHD profile with the additional support for imaging documents such as an imaging manifest. MHD-I provides access to DICOM instances via the WADO-URI and WADO-RS Retrieve methods.

Product Type

P

Actors
PACS IHE - Very Important Imaging Document Consumer
VNA IHE - Very Important Document Responder
Enterprise Viewer IHE - Very Important Imaging Document Consumer

Note: Those interested in MHD-I should monitor the progress of IHE CP-314 (link is to a Word doc on an FTP site) as it is intended to make significant revisions to this integration profile, including the use of a FHIR resource instead of a the JSON format manifest specified in the current profile.

Web-based Image Capture (WIC)

The Web-based Image Capture (WIC) profile provides a simple, lightweight, mobile-friendly mechanism to encode and send captured images, videos and evidence documents from a mobile device to an Image Manager so that these objects can be easily integrated into the rest of the imaging record.

Product Type P Actors
PACS IHE - Important Image Capturer
IHE - Important Image Manager/Archive
VNA IHE - Very Important Image Manager/Archive
Enterprise Viewer IHE - Very Important Image Capturer

Invoke Image Display (IID)

The Invoke Image Display profile allows the user of an Image Display Invoker, typically a non-image-aware system like an EHR, PHR or RIS, to request the display of studies for a patient, and have the display performed by an image-aware system like an Image Display (Enterprise Viewer).

Product Type P Actors
PACS IHE - Important Image Display
Enterprise Viewer IHE - Very Important Image Display

Digital Breast Tomosynthesis Extension (DBT Extension) 

The Digital Breast Tomosynthesis (DBT) Extension profile specifies the creation, exchange, and use of DBT images. It defines basic display capabilities that Image Displays are expected to provide, especially simultaneous review of 3D DBT and conventional 2D mammography images (FFDM).

As this profile has reached Final Text status, it has been added to the IHE Buyers’ Guide.

Management of Radiology Report Template (MRRT)

This workflow profile concerns the use of imaging report templates to create diagnostic imaging reports. This profile distinguishes between report authoring templates, which are templates used by Radiologists to guide the creation of a clinical imaging report, and report instance templates, which describe technical constraints on the structure and content of imaging report instances, such as the constraints described in and XML schema or the HL7® Clinical Document Architecture. This profile applies to the former, report authoring templates, and describes methods for the formatting of imaging report templates and the management of their transport between template libraries and report creation systems. Specifically, this profile describes an enhanced feature set for report authoring templates, delineates how such templates from a vendor-agnostic template library could be used immediately by a reporting system, and provides a format for migration of templates between reporting systems.

Product Type P Actors
PACS IHE - Not Important Report Template Manager
IHE - Not Important Report Template Creator
IHE - Not Important Report Creator
VNA IHE - Not Important Report Template Manager
RIS IHE - Important Report Template Manager
IHE - Important Report Template Creator
IHE - Important Report Creator
Enterprise Viewer IHE - Not Important Report Creator

Note: The priority for Report Template Manager and Report Template Creator are not rated as a higher priority as these are likely to be provided by an online service, such as RadReport.org, rather than an on premise system.

Clinical Decision Support – Order Appropriateness Tracking (CDS-OAT)

This profile is intended to propagate the Clinical Decision Support and Appropriate Use Criteria (AUC) information throughout the existing Radiology Scheduled Workflow transactions. It is designed to work with the CDS Profile in IHE Patient Care Coordination (PCC) – Guideline Appropriate Ordering (GAO), which focuses on obtaining the CDS information and the interaction between the Order Placer and the CDS system.

Product Type P Actors
RIS IHE - Important Order Placer
IHE - Important DSS/Order Filler
IHE - Important Report Manager
IHE - Important Charge Processor

Note: As mentioned here, there was a delay by PAMA in the date for the required use of CDS.

Information Technology Infrastructure (ITI)

Mobile Access to Health Document (MHD)

The Mobile access to Health Documents (MHD) profile defines one standardized interface to health documents (a.k.a. an Application Programming Interface (API)) for use by mobile devices so that deployment of mobile applications is more consistent and reusable within a single policy domain. MHD can be used to allow mobile devices, or other resource-constrained systems, access to an XDS Repository, but MHD transactions are not specifically tied to XDS; some of the system implementations envisioned may interface directly to an organizational EHR, or a multi-national PHR.

Product Type P Actors
PACS  IHE - Very Important Document Consumer
VNA  IHE - Important Document Responder
RIS  IHE - Very Important Document Source
 IHE - Very Important Document Consumer
Enterprise Viewer  IHE - Very Important Document Consumer

Patient Identifier Cross-reference for Mobile (PIXm)

The PIXm profile exposes the functionality of a Patient Identifier Cross-reference Manager to mobile applications and lightweight browser applications.

Product Type P Actors
PACS  IHE - Important PIX Consumer
VNA  IHE - Important PIX Consumer
Enterprise Viewer  IHE - Important PIX Consumer

Note: If any of the above systems are expected to interface with a PIX Manager that supports PIXm, the priority would obviously be Very Important.

Patient Demographics Query for Mobile (PDQm)

The PDQm profile exposes the functionality of a patient demographics supplier to mobile applications and lightweight browser applications.

Product Type P Actors
PACS  IHE - Important Patient Demographics Consumer
VNA  IHE - Important Patient Demographics Consumer
Enterprise Viewer  IHE - Important Patient Demographics Consumer

Note: If any of the above systems are expected to interface with a Patient Demographics Supplier that supports PDQm, the priority would obviously be Very Important.

XDS Metadata Update

This supplement updates the XDS and XDR profiles to add support for the updating and deleting of metadata.

Product Type P Actors
PACS  IHE - Very Important Document Administrator
VNA  IHE - Very Important Document Administrator
 IHE - Important Document Registry
RIS  IHE - Important Document Administrator
Enterprise Viewer  IHE - Not Important Document Administrator

Note: Any system that is a Document Source actor in XDS should also be a Document Administrator actor. If a VNA is an XDS Document Registry actor, then its priority would be Very Important.

Mobile Alert Communication Management (mACM)

The mACM profile provides the infrastructural components needed to send short, unstructured text alerts to human recipients and records the outcomes of any human interactions upon receipt of the alert. The mACM Profile additionally allows for a feedback mechanism to determine the status of an alert through the use of alert statuses. This profile limits to two use cases:

  • Crisis Response: Covers the distribution of notifications to health workers.
  • Care Reminders: Covers the distribution of notifications to care givers and subjects of care based on upcoming or missed appointments as defined, medication reminders and other similar patient care reminders.
Product Type P Actors
PACS  IHE - Not Important Alert Reporter
VNA  IHE - Not Important Alert Reporter
RIS IHE - Not Important Alert Aggregator
Enterprise Viewer IHE - Not Important Alert Reporter

Note: It is expected that these capabilities are more likely sought in an EHR system, but depending on the intent, the priority may be higher for some buyers.

Internet User Authorization (IUA)

IHE - Important Important for any system using a RESTful API.
