1.0 Introduction

1.1 Overview

The goals supported by this Transaction specification are the following:

Transmission of complete, preliminary, final and updated laboratory results to the EHR system (local or remote) of the ordering clinician and providers of care

Transmission of complete, preliminary, final and updated laboratory results (or notification of the availability of laboratory results) to the EHR system (local or remote)

This Transaction is the result of an assessment of the current practices in electronic laboratory results reporting and the requirements of the Electronic Health Records Laboratory Result Reporting Use Case. In order to encourage rapid and widespread adoption of this Transaction, HITSP placed emphasis on the operations and process flows of current implementations and the ease with which current implementations can become compliant. Health Level (HL7) Version 2.x [1] message-based laboratory result reporting is the most common electronic interface in existence today and HITSP did not want to invalidate those interfaces.

This Transaction is an initial step in establishing a baseline of performance for all stakeholders. It raises everyone to a modern version of HL7 2.x and establishes some discipline in identity management and vocabulary.

1.4 Conformance

This section describes the conformance criteria, which are objective statements of requirements that can be used to determine if a specific behavior, function, interface, or code set has been implemented correctly.

1.4.1 Conformance Criteria

In order to claim conformance to this construct specification, an implementation must satisfy all the requirements and mandatory statements listed in this specification, the associated HITSP Interoperability Specification, its associated construct specifications, as well as conformance criteria from the selected base and composite standards. A conformant system must also implement all of the required interfaces within the scope, subset or implementation option that is selected from the associated Interoperability Specification.

Claims of conformance may only be made for the overall HITSP Interoperability Specification or Capability with which this construct is associated.

1.4.2 Conformance Scoping, Subsetting and Options

A HITSP Interoperability Specification must be implemented in its entirety for an implementation to claim conformance to the specification. HITSP may define the permissibility for interface scoping, subsetting or implementation options by which the specification may be implemented in a limited manner. Such scoping, subsetting and options may extend to associated constructs, such as this construct. This construct must implement all requirements within the selected scope, subset or options as defined in the associated Interoperability Specification to claim conformance.
