Governments worldwide are facing the challenges of ageing populations. ◦ Europe – population aged >65 expected to rise
from 17% (2008) to 30% (2060) (Eurostat, 2008) ◦ NZ – population aged >65 expected to rise from
12.1% (2010) to 25% (2050) More elderly and fewer people to support
them (Dunstan & Thomson, 2006) Spending: 65+ (double), 75+ (triple), 85+
(8x) (OECD 2001)

“...people should be able to continue living in their own place of residence in their later years...” (Jorgensen et al. 2009)
New Zealand District Health Boards contract for support services to be provided to older people in their own homes based on their level of need
Traditional view ◦ Fee for service ◦ Output has been identified with inputs i.e.
resource provision (hours of care) ◦ Clinicians’ view – everyone is unique

The major problem in health care is to manage complexity (i.e. variety)
Therefore, our task was to identify factors that help reduce (or amplify) complexity in the context of Home-based Support Services.

…is a system that classifies patients into groups that are homogeneous in their use of resources (Palmer, 1996; Zbylot, Job, McCormick, Boulter, & Moore, 1995)
Case mix complexity - Diagnosis Related Groups (DRGs) (Fetter et al. 1980). DRGs were designed to be homogeneous units of hospital
activity (e.g. nursing, diagnostic services, procedures) the best-known classification system that are used in the
case-mix funding model

Qualitative interviews with regulators and providers ◦ Differing views on case mix complexity Severity & need for intervention (clinician) Resource intensity (regulator)
Collected quantitative data for 1,101 clients Holistic assessment tool ◦ ADL (e.g. bathing), Instrumental ADL (e.g. Ordinary
housework) Collection of activity and cost data

Attenuators – reduction of variety using typologies
Amplifiers – technology, information and
networks
Law of requisite variety for homeostasis
Informal carers, telemedicine, social
networks
Capacity Capabilities
The amount of appropriate selection that can be performed is limited by the amount of information available. More information might be wasted but less information results in arbitrary decisions. ◦ the greater the variety within a system, the greater
its ability to reduce variety in its environment through regulation. ◦ Only variety can destroy variety (in the system being
regulated).

‘Housework’ masks ‘shopping support’ (unable to drive, growing disability, risk of loneliness/isolation)
Demonstrate that homecare settings are potentially fruitful avenues for research on service provision and co-creation
“going to someone’s home and preparing a breakfast meal would be a relieving process (direct service provision), while providing a toaster so that the customer can provide self-service is an enabling (indirect service provision) process.” (Vargo & Lusch, 2007)

We draw on cybernetics and the law of requisite variety to identify and manage (attenuators and amplifiers) variety ◦ Influence on resource use and integration ◦ Influence the shape of the market
Role of informal helpers: a person co-creates on-going experiences with a patient. ◦ Various roles ◦ Mediated value proposition ◦ Reiterates the process of voluntary exchange
through collaborative relationships that create reciprocal value through the application of complementary resources.
