HISO 10072.1:2022 Bowel Screening Histology Data Standard

The National Bowel Screening Programme (NBSP) is a free programme for men and women aged 60–74 years who are eligible for publicly funded health care. The primary objective of bowel screening is to reduce the mortality rate by diagnosing and treating bowel cancer at an earlier, more treatable stage. The introduction of the NBSP in New Zealand followed a successful six-year pilot.

The new NBSP information technology system is called the National Screening Solution (NSS). This system will enable easy management of the bowel screening pathway, support planning and management of participants, monitor safety and quality, and enable ongoing evaluation of the programme. The NSS is a long-term strategic solution that can be extended to support future population health initiatives.

HISO 10072.1:2019 Bowel Screening Histology Data Standard identifies and describes the data elements that the laboratories contracted to perform NBSP histology services need to capture in their information systems. This data will support the monitoring, operation and quality of the NBSP and may also be used for research and education purposes.

The standard is designed to ensure that consistent information is sent from contracted laboratories to the NSS.

This standard should be read in conjunction with the implementation guide: HISO 10072.2:2019 Bowel Screening Messaging Implementation Guide.

Adoption plan

The National Bowel Screening Programme will be working with the current bowel screening providers and laboratory information system vendors to implement the standards. They will also work with new vendors, laboratories and district health boards as they come on board with the Bowel Screening Programme over the next year.

A review may be required in one year to ensure the standards are fit for purpose, based on implementation experience.  

An indicative timeframe of two years to adopt the standards will be included in the Laboratory Information Standards Adoption Roadmap. HISO will work with the National Bowel Screening Programme to track the level of adoption by laboratories, vendors and district health boards. 

HISO 10004:2022 New Zealand Pathology Observation Code Sets

The New Zealand Pathology Observation Code Sets (NZPOCS) standard comprises code sets for ordering and reporting laboratory tests and results. HISO maintains NZPOCS in partnership with the National Pathology and Laboratory Round Table.

The code sets are based on international standards Laboratory Observation Identifiers Names and Codes (LOINC) and SNOMED CT, and cover all commonly performed pathology tests in biochemistry, haematology, immunology, microbiology, virology/serology and toxicology. NZPOCS will be extended to new test types such as molecular tests and multidrug-resistant organism screening tests.

NZPOCS April release

Coding for COVID-19 lab tests

LOINC codes are continuously being created in response to the COVID-19 pandemic. The LOINC codes that are developed between release cycles have a status of ‘special use’. The codes are still in development and are subject to change, prior to being included in a scheduled release. The NZPOCS list includes some of these codes.

See the LOINC website for more information on the COVID-19 test codes.

Microorganism code set

NZPOCS now has a microorganism code set that includes all 18,000 concepts in the SNOMED microorganism hierarchy. The code set is published in the SNOMED NZ Edition.

This choice of code set of was agreed in 2018 between HISO, the National Pathology and Laboratory Round Table and the New Zealand Microbiology Network. Laboratory information managers and their industry partners were consulted on the changes at the time.

The code set considerably extends the Royal College of Pathology of Australasia (RCPA) microorganism code set of about 3000 concepts, to provide better cover and avoid difficulties in using and maintaining a restricted set. We will work with our RCPA partners when requesting additions to the microorganism content in SNOMED.

A related decision concerns how resistance mechanisms such as methicillin resistant staphylococcus aureus (MRSA), extended spectrum beta lactamase (ESBL) and vancomycin resistant enterococcus (VRE) are recorded. In these cases, the decision is to code the microorganism and the resistance mechanism as separate data elements in the report. Resistance mechanism should be coded as a SNOMED concept under Infection caused by resistant organism (disorder). We will work with RCPA on any additions needed.

HISO's expectation is that SNOMED will be implemented in all systems exchanging laboratory information, for end-to-end interoperability that doesn’t depend on mapping. This applies to laboratory information systems and repositories, infection control systems and clinical information systems.

SNOMED NZ Edition

The SNOMED NZ Edition can be downloaded in standard release file format from the SNOMED Member Licensing and Distribution Service. Laboratory information systems need to be loaded with each new release to stay up-to-date with the microorganism code set.

Other developing content in the SNOMED NZ Edition includes the RCPA laboratory order code set.

The SNOMED browser and the SNOMED reference set tool are available to end users and developers for viewing and downloading content such as the microorganism code set.

HISO 10008.4:2020 COVID-19 Messaging Implementation Guide

This is an implementation guide that provides details for using electronic messaging to submit COVID-19 laboratory results into the COVID-19 result repository. 

This document details the specific structure for electronic messages using the HL7 version 2.4 messaging standard. The implementation guide is designed to ensure that laboratory test results are submitted into the repository in a structured and consistent way.

This document is published as a draft standard that will be updated to reflect new requirements, as they emerge.

HISO 10008.3:2019 Notifiable Disease Messaging Implementation Guide

This implementation guide forms part of HISO 10008: Pathology and Radiology Implementation Guide and Messaging standard. The guide provides assistance in the development of applications using structured messaging to specifically report notifications into the Electronic Notifiable Disease Messaging System (ENDMS).

This document presents guidelines for sending HL7 version 2.4 messages and covers:

  • specific use of message segments where there are alternative uses, and the enforcement of optional fields that are required for the ENDMS
  • provision of technical information required for a health provider (or their system vendor) to make all the necessary system changes to support the ENDMS.

Note: This standard was updated on 8 July 2022 to include a disease code for Monkeypox in order that systems are able to report instances of this disease to ESR if needed.

 

HISO 10008.1:2015 Pathology and Radiology Implementation Guide

This implementation guide forms part of the standard HISO 10008, which details the structure of electronic messages for Pathology and Radiology orders and results. The guide provides assistance and guidance for implementers.

The guide should be read in conjunction with HISO 10008.2:2015 Pathology and Radiology Messaging Standard.

This standard provides data definitions and includes the data segments and data elements that are mandatory (required), optional or conditional (required, based on a condition), together with a commentary and relevant notes for usage in the New Zealand health environment.

HISO 10008.2:2015 Pathology and Radiology Messaging Standard

This standard details the structure of electronic messages for Pathology and Radiology orders and results. It is based on HL7 version 2.4.

This standard provides consistent data definitions and includes the data segments and data elements that are mandatory (required), optional or conditional (required, based on a condition), together with a commentary and relevant notes for usage in the New Zealand health environment.
