In the days and weeks after the Canterbury earthquake, emergency response teams needed to be able to identify and support people who were at risk of adverse outcomes from a health perspective.
These people were not acutely injured during the earthquake itself. They were a potentially sizeable population of frail elderly living in the community in their own homes. They often have multiple co-morbidities and due to their low resilience could have ‘tipped over’ into needing acute care services very rapidly.
The implementation of interRAI, a national assessment tool being used by all District Health Boards allowed Canterbury DHB to receive prioritised lists from the national interRAI data warehouse, of ‘at risk’ elderly to assist the response teams to target their services.
In addition, subsequent to the earthquake a number of elderly people were moved from their homes and residential care facilities to other parts of the country. The national interRAI system was able to seamlessly move assessment and care plan records to the receiving District Health Board so that the receiving services could continue care appropriately.

A Novel Use of a Clinical System to Assist Emergency Teams to Support the Frail and Vulnerable Elderly after the Canterbury Earthquake
1. A novel use of a clinical assessment system to assist
emergency teams to support the frail and vulnerable
elderly after the Canterbury earthquake

2. Describe the system
interRAI
How it is used today in New Zealand
How interRAI information was used
post earthquake
3. interRAI - clinical assessment and care
planning methodology
interRAI (www.interRAI.org) is a not for
profit collaborative network of 60
researchers and health/social service
professionals in over 30 countries
Their goal is to promote evidence-based
clinical practice and policy decisions
through the collection and interpretation
of high quality data about the
characteristics and outcomes of persons
served across a variety of health and
social services settings.
4. Single assessment framework – many areas of
health care
At least 80% of items common across the suite:
Contact Assessment (screener assessment)
Home Care
Long Term Care Facility
Assisted Living
Acute Care
Post Acute Care
Mental Health Care
Community Mental Health
Palliative Care
Quality of life
5. If you are going to assess somebody make sure
you cover at least these domains...

11. At risk population (s) post earthquake
Frail elderly...
Frailtyencompasses many dimensions including but
not limited to; functional capability, physiological
reserve, cognitive performance, disease
progression and disease instability.
.....who are also vulnerable
Vulnerability encompasses dimensions such as
whether someone lives alone, the strength of their
support networks both formal and informal,
loneliness and the persons cognitive performance
(especially in relation to decision making).

“if the RAI-HC is fully rolled Hirdes sends draft algorithm
out in Christchurch and you are code to NZ group
able to obtain person-level
outputs, you should be able to
get a list of vulnerable seniors
who may be in need of extra
help at this point”.

15. Initial NZ Earthquake Algorithm (Principles)
(Source: Back of Napkin)
Identify those with immediate (emergent) risk
with limited caregiver support
a) Isolated or distressed caregiver
b) Vulnerable (and frail)
Twitter: @interRAI_Hirdes
16. The risk profile (Source: Back of Napkin)
Lives alone, no primary helper, any signs of caregiver
distress, poor vision, difficulty with meal
preparation, difficulty with managing medications
Had Cognitive Performance Score (CPS) of >2.
the CPS score is an interRAI outcome measure scored from 1-6 where 1= no
cognitive impairment and 3-6 = moderate to severe cognitive impairment.
Elements that make up the CPS score include decision making ability, memory
loss, ability to make self understood and ability to manage eating. A score of >2
indicates early onset of cognitive issues eg memory loss.
Had CHESS score > 2
the CHESS score is an interRAI ‘frailty/stability’ measure scored 1-5 where 1=
person is stable and 5= highly unstable. Elements that make up the CHESS score
include presence of vomiting, oedema, shortness of breath, weight loss, decrease
in food or fluid, insufficient fluid intake, decline in ADLs, decline in decision
making and any end stage disease.
Had ADL score >2
The ADL score is scored from 1 – 6 where 1= no problems with ADL and 6 = fully
dependent in washing and dressing, toileting , eating and locomotion.
17. Clinical prioritisation (Source: Back of Napkin)
Many items common across most clients, the data was
grouped based on the outcome scores to support quicker
prioritisation
Group 1 (most likely highest priority)
all those WHERE CPS > 2 AND CHESS >2 AND ADL >2 –
approximately 100 people
Group 2 (most likely next priority)
all those WHERE score >2 in ANY two of: CPS OR ADL
OR CHESS - approximately 250 people
Group 3 (most likely next priority)
All those WHERE score >2 in ANY one of: CPS OR ADL
OR CHESS – approximately 400 people

“Add diabetes and ver[y] advanced age. Great idea. I suggested this
for Katrina but no one listened”
Feb 23/11 3:26 am (Downes)
“Nigel & the Canterbury response teams have now had a copy of
the list of vulnerable seniors.What a great international effort and one
based on real life up to date accurate person level data”
Within 24 hours a great set of data for use
