3.0Capability Specifications

3.1 Capabilities Overview

This section provides an overview of Capabilities including typical topologies, descriptions of Service Collaborations used in Capabilities and global constraints applied to all Capabilities.

3.1.1 Introduction

This section provides guidance and specifications for implementing Capabilities and underlying Service Collaborations that are supported by EHR systems. In addition there is a brief description of network topologies that can be supported by Capabilities.

Capability Specifications can be implemented by EHR systems to fulfill business requirements, such as those described in the ARRA. Capabilities are implementable business services that specify interoperable information exchanges using HITSP constructs. Capabilities may be combined by an Interoperability Specification to address more inclusive requirements for example, support for the formal process of medication reconciliation can be addressed when HITSP/CAP118 Communicate Hospital Prescription is associated with HITSP/CAP119 Communicate Structured Document (medications and allergies).

Each Capability section defined later in this section contains an overview, the participating systems, a list of the HITSP constructs used and a detailed design section including constraints and interfaces. All Capabilities are based on EHR system information exchanges that are defined in the existing HITSP Interoperability Specifications.

3.1.2 Typical Topologies supported by Capabilities

Topologyis the arrangement or mapping of networked Systems, especially the physical (real) and logical (virtual) interconnections between Systems. A Health Information Exchange(HIE) is a special network system that provides intermediary services, such as directories, registries or translations. Networks exhibit both a physical topology and a logical topology. Figure 3-1 Typical Network Topologies illustrates possible interconnections between systems employing HITSP Specifications.

Figure 3-1 Typical Network Topologies

The following matrix portrays which of the typical network topologies in the U.S. are addressed within each Capability. Within each cell, a Y indicates that the topology is addressed while an N indicates that the topology is not supported/not necessary.

Type of Constraint

Systems store patient data as an encounter. A patient has one to many encounters linked into episodes of care. Each encounter holds documents. Each document holds data. This is analogous to each encounter being a report holding many paper document sections and each document section containing many data elements. An episode of care contains many reports on the same incident. The file folder also contains incident information on the same topic (e.g., patient). We assume data are communicated in both document and message forms

Assumption

Ability to identify and request corrections to errors is available

Pre-Condition

Ability to apply notes, corrections and comments on original entries is available

Pre-Condition

Table 3-28 Constraints and Assumptions

Constraint

Type of Constraint

Systems store patient data as an encounter. A patient has one to many encounters linked into episodes of care. Each encounter holds documents. Each document holds data. This is analogous to each encounter being a report holding many paper document sections and each document section containing many data pieces. An episode of care contains many reports on the same incident. The file folder also contains incident information on the same topic (e.g., patient). We assume data are communicated in both document and message forms

Assumption

Ability to identify and request corrections to errors is available

Pre-Condition

Ability to apply notes, corrections and comments on original entries is available

Pre-Condition

Appropriate standards are developed, approved, and widely adopted supporting data content and structure, allowing universal access by compliant systems

Pre-Condition

Core datasets are defined and adhered to

Pre-Condition

Method to query other organizations for data and matching to the consumer is available

Pre-Condition

If physical media is used for the transport, when the media is read the consent directives stored on the portable media need to be enforced by the portable media importer. The validity of these content directives may need to be checked

Post-Condition

HITSP/C34 Patient Level Quality Data Message

The HITSP Patient Level Quality Data Message Component supports the process of sending patient data from a Quality Message Sender to a Quality Message Receiver for further analysis and aggregation. Patient data are captured as part of the normal process of care performed by healthcare providers such as hospitals, emergency departments and outpatient clinics

HITSP/SC112 Healthcare Document Management

The HITSP Healthcare Document Management Service Collaboration provides the ability to share healthcare documents using a set of topologies, such as Media, e-Mail, Point-to-Point, Shared within a Health Information Exchange, and Shared within a larger community (made up of potentially diverse Health Information Exchanges)

HITSP/SC115 HL7 Messaging

The HL7 Messaging service collaboration provides the capability to send and receive HL7 messages. The Service Collaboration applies the necessary Security and Privacy constructs

HITSP/C26 - Nonrepudiation of Origin

The Nonrepudiation of Origin Component provides the mechanisms to support Nonrepudiation of Origin, which refers to both the proof of the integrity and origin of documents in a high-assurance manner, which can be verified by any party. This Component does not provide Nonrepudiation of Receipt

3.14.2.5 Capability Options

Note that subsets of the data content can be sent as appropriate for the application; but the system must be able to address the entire data content. Note that transport options can be addressed.

3.15 HITSP/CAP130 Communicate Quality Measure Specification

3.15.1 Overview

This capability addresses interoperability requirements for an EHR-compatible, standards-based quality measure. In the measure specification, needed patient encounter data elements are identified so they can be extracted from local systems and from longitudinal data available through other sources such as a Health Information Exchange (HIE). The measure specification also includes various sets of exclusion/inclusion criteria to identify which patients to include in calculation of the measure. This capability may use Value Set Sharing.

3.15.2.2 Constraints and Assumptions

This section provides an overview of the constraints (i.e., Assumptions, Pre-conditions, Post-conditions, Triggers) associated with the Capability.

Table 3-78 Constraints and Assumptions

Constraint

Type of Constraint

Hospitals and clinicians will only receive measures applicable to their population

Pre-condition

New measure or updated measure is ready to be communicated to publish, record, send, or review

Trigger

Quality measures are provided with sufficient specification to enable the electronic upload and processing of queries without the need for local interpretation. Limitation on potentially ambiguous criteria should be part of the measurement endorsement process. Measures are unambiguous, well-defined

Description

HITSP/C26 - Nonrepudiation of Origin

The Nonrepudiation of Origin Component provides the mechanisms to support Nonrepudiation of Origin, which refers to both the proof of the integrity and origin of documents in a high-assurance manner, which can be verified by any party. This Component does not provide Nonrepudiation of Receipt

HITSP/C106 Measurement Criteria Document

This Component supports communication of a quality measure (aka an "eMeasure"). Clinical concepts (e.g. "atrial fibrillation", "coronary artery disease") and parameters (e.g. "numerator", "denominator") in an eMeasure are formally defined to support consistent and unambiguous interpretation. The eMeasure is standardized as a structured document, where one can capture the complete narrative of the measureand a formalized computable representation of statements

HITSP/SC108 Access Control

The HITSP Access Control Service Collaboration provides the mechanism for security authorizations which control the enforcement of security policies including: role-based access control, entity based access control, context based access control, and the execution of consent directives
