The NZACA promotes excellence amongst its member homes that are situated throughout New Zealand


This section is a compendium of information relating to interRAI.

It includes links to documents and presentations that discuss using interRAI outputs to support care planning and quality improvement in ARC, links to reports that demonstrate the benefits of ARC to its residents and so support the NZACA’s government and public communications, and links to guidance on how to carry out interRAI assessments more efficiently.


Integrating interRAI in your care facility workshops

NZACA and interRAI Services are jointly conducting a series of workshops for ARC managers, care managers, clinical managers and lead interRAI RNs on how to further integrate interRAI into their care facilities’ operations.

The purpose of the workshops is to update managers and lead interRAI RNs on:

  • the opportunities for efficiency gains and other improvements linked to the interRAI process
  • the new InterRAI New Zealand National Standards – how these influence the assessment process
  • considerations for changes in Level of Care
  • how accessing the interRAI Home Care assessment can inform short term care planning in ARC
  • CAPs and Outcome measures, and their use
  • what the interRAI Quality indicators and Quarterly Reports for care facilities tell us

Caring for our older kiwis: the right place, at the right time

The NZACA engaged John McDougall, Data analyst in December 2016 to enhance the evidence base underpinning the aged residential care sector’s discussions with the Government.  The Caring for our older Kiwis report is based on analysis of interRAI assessment data.
One of the goals of the analysis was to show what happens to the health and social outcomes of an older person when they enter aged residential care. Because of this data analysis, we now have evidence that health and social outcomes significantly improve. The other goal was to evaluate the consistency of older people’s access to aged residential care across the DHB regions. First, we looked at access to aged residential care i.e. all care level combined. Next, we examined access of older individuals with very high support needs to hospital, dementia or psychogeriatric care levels within aged residential care. The analysis provides evidence of inconsistencies between DHBs in both.

The data provided to NZACA by interRAI New Zealand is anonymised, so neither the individuals nor their care facilities can be identified.  NZACA matched the assessments for a given (anonymised) individual and carried out longitudinal analysis of changes in their interRAI outcome scores.

The second presentation was given by an interRAI New Zealand team lead by Michele McCreadie, General Manager. The topic of the presentation was How we are all doing: interRAI and quality.  The presentation covers, first, the results of an investigation into interRAI data quality issues.  Second, it introduces interRAI Quality Indicators and how facility managers can interpret and make use of their confidential facility reports.

Completing interRAI assessments efficiently

Discussion at the integrating interRAI in your care facility workshops has revealed that some interRAI assessors are continuing to use outdated editions of the National Standards.  This may be contributing to some interRAI assessments taking longer than is necessary.  The National Standards give guidance on how to carry out assessments efficiently, for example, by keeping comments concise.
A new edition of the LTCF National Standards (dated October 2018) has been published by interRAI NZ and is available at
