Defining integration (again)
Economic approaches- markets vs. hierarchies vs. networks- transaction cost economics
(Williamson, 1975)
Organisational theory - integration/differentiation in organisationaldesign
- degree of co-ordination among unitswithin organisations

Integrated health care
‘Integrated care is a concept bringing together inputs, delivery, management and organisation of services related to diagnosis, treatment, care, rehabilitation and health promotion. Integration is a means to improve services in relation to access, quality, user satisfaction and efficiency’
(WHO, 2002)
![Page 5: Naomi Fulop: What can the evidence tell us](https://reader033.vdocuments.us/reader033/viewer/2022052905/55840657d8b42af00a8b5027/html5/thumbnails/5.jpg)

Need for integrated health care“The current care systems cannot do the job.Trying harder will not work, changing systems of care will.”
Need systems of care in which “clinician andinstitutions… collaborate and communicate toensure appropriate exchange of information andco-ordination of care”
(Institute of Medicine, Crossing the Quality Chasm, 2001)

Types of organisational integration
Vertical- combination of firms at different stages of the
production process, with a single firm producing the goods or services that either suppliers or customers could provide
Horizontal- combination of two or more firms producing similar
goods or services.

Drivers of vertical integration
Improve quality of care, esp for long term conditions
Savings in transaction costs (esp where integration of payer and provider)
Economies of scale and scope Managerial control

Types of vertical integration
where agencies involved at different stages of the care pathway are part of a single organisation
where payer and provider agencies are part of a single organisation
networks/virtual integration

Typologies of integration (1)
(Shortell, 1996, 2000)
Functional + Physician = Clinical
Integration of support, functions eg. Finance, HR, IT etc
Clinician alignment with aims of delivery system
Extent to which patient care services are co-ordinated across people, functions, activities and sites over time
![Page 11: Naomi Fulop: What can the evidence tell us](https://reader033.vdocuments.us/reader033/viewer/2022052905/55840657d8b42af00a8b5027/html5/thumbnails/11.jpg)

Typologies of integration (2)
Denis et al add: Normative integration – role of values Systemic integration – coherence of rules and
priorities
![Page 12: Naomi Fulop: What can the evidence tell us](https://reader033.vdocuments.us/reader033/viewer/2022052905/55840657d8b42af00a8b5027/html5/thumbnails/12.jpg)

How integration can occur
Three possible directions: Hospital trusts expand outwards and downwards Primary care trusts expanding outwards and
upwards Formation of new organisations of delivery
(Feachem and Sekhri, 2005)

Nature of the evidence
Limited – a lot on processes, less on outcomes Quite a lot from US More recently, evidence from other more
comparable health care systems Little large scale evaluation Evaluation of ‘boutique’ pilots (Ouwens et al, 2005)
![Page 14: Naomi Fulop: What can the evidence tell us](https://reader033.vdocuments.us/reader033/viewer/2022052905/55840657d8b42af00a8b5027/html5/thumbnails/14.jpg)

Summary of evidence (1) Summary of the impact of integration of payment and provision Most evidence from US (e.g. Burns and Pauly, 2002; Enthoven and Tollen, 2004) , but
also Italy, Canada and UK (Johri et al, 2003)
Perceived improved partnerships increased focus on case management and use of IT systems
important some increases in capacity are reported, but not quantified mixed evidence on admissions and lengths of stay (e.g. Evercare in
England) mixed evidence on costs, with little information available from the
NHS domain; and inconsistent information internationally.

Summary of evidence (2) Summary of the impact of integration of provision Evidence from US, UK, Sweden and the Netherlands (eg. Ouwens et al, 2005)
Models from England – Care Trusts, Unique Care Some evidence of strengthened partnerships organisational integration being hampered by lack of coordination at
national policy level some reports of improved capacity, e.g. personnel improved focus on governance and adherence to guidelines little evidence of impact on health outcomes limited evidence of impact on cost
![Page 16: Naomi Fulop: What can the evidence tell us](https://reader033.vdocuments.us/reader033/viewer/2022052905/55840657d8b42af00a8b5027/html5/thumbnails/16.jpg)
16
Summary of evidence (3) Summary of the impact of networks e.g. managed clinical networks in Scotland, Chains of
Care in Sweden mixed evidence: while some cases show improved
communication across organisations and with patients, others show key personnel resistant to role changes;
some evidence of improvements in care provision, but few statistically significant; and
little evidence of improvements in costs or health outcomes.

Lessons
Lesson 1. Integrate for the right reasons Objectives of integration need to be made explicit Is it to improve quality of care, reduce costs,
both? Can objectives be achieved in other ways? Are new services related to core business? –
unrelated diversification may not create real value (Burns and Pauly, 2002)
![Page 18: Naomi Fulop: What can the evidence tell us](https://reader033.vdocuments.us/reader033/viewer/2022052905/55840657d8b42af00a8b5027/html5/thumbnails/18.jpg)

Lessons Lesson 2. Don’t necessarily start by integrating
organisations Integration that focuses mainly on bringing organisations
together is unlikely to create improvements in care for patients.
Some evidence that more successful integration can be achieved through formal and informal clinical integration (King et al, 2001)
Excessive focus on patient pathways might lead to a loss of the benefits of overall service coordination, e.g. in managing co-morbidities.
![Page 19: Naomi Fulop: What can the evidence tell us](https://reader033.vdocuments.us/reader033/viewer/2022052905/55840657d8b42af00a8b5027/html5/thumbnails/19.jpg)

Lessons Lesson 3. Ensure local contexts are supportive of
integrationKey contextual elements: a culture of quality improvement a history of trust between partner organisations existent multidisciplinary teams local leaders who are supportive of integration personnel who are open to collaboration and innovation effective and complementary communications and IT
systems.
![Page 20: Naomi Fulop: What can the evidence tell us](https://reader033.vdocuments.us/reader033/viewer/2022052905/55840657d8b42af00a8b5027/html5/thumbnails/20.jpg)

Lessons
Lesson 4. Be aware of local cultural differences
significant challenge of bringing together organisational cultures that have, in many cases, evolved separately over decades.
e.g. seems to be particularly challenging when attempting to integrate health and social care
![Page 21: Naomi Fulop: What can the evidence tell us](https://reader033.vdocuments.us/reader033/viewer/2022052905/55840657d8b42af00a8b5027/html5/thumbnails/21.jpg)
21
Lessons
Lesson 5. Ensure that community services don’t miss out
Integration of acute and primary/community services may prove detrimental to primary/community services due to longstanding power imbalances esp with regard to distribution of resources (King et al, 2001)
Evidence that integration led from primary sector more successful than integration led from acute sector (Enthoven and Tollen, 2004; Burns and Pauly, 2002)
![Page 22: Naomi Fulop: What can the evidence tell us](https://reader033.vdocuments.us/reader033/viewer/2022052905/55840657d8b42af00a8b5027/html5/thumbnails/22.jpg)
22
Lessons
Lesson 6. Give the right incentives If trying to reduce use of hospital beds, need to
address PbR (e.g. through pooled budgets, sharing risks between primary care and hospitals)
Incentives for frontline staff required – raises issues e.g. for GP contract
![Page 23: Naomi Fulop: What can the evidence tell us](https://reader033.vdocuments.us/reader033/viewer/2022052905/55840657d8b42af00a8b5027/html5/thumbnails/23.jpg)
23
Lessons Lesson 7. Don’t assume economies of scope and
scale Potential economies of scope and scale are likely to take
time to achieve integration has seldom increased efficiency - evidence
from the US (e.g. Burns and Pauly, 2002; Robinson, 2004)
‘integration costs before it pays’ (Leutz, 1999) e.g. due to significantly different practices in organisations to be integrated
‘make or buy’ decision bigger problem for primary care taking over hospital services than hospitals undertaking ‘outreach’ – changes in technology
![Page 24: Naomi Fulop: What can the evidence tell us](https://reader033.vdocuments.us/reader033/viewer/2022052905/55840657d8b42af00a8b5027/html5/thumbnails/24.jpg)

Lessons
Lesson 8. Be patient Time required to implement effective integration
is a recurrent theme and is unsurprising given the changes required to address all six elements of integration.
Takes time to effect demonstrable changes in organisational structures, and to processes; and to have these filter down to outcomes.
![Page 25: Naomi Fulop: What can the evidence tell us](https://reader033.vdocuments.us/reader033/viewer/2022052905/55840657d8b42af00a8b5027/html5/thumbnails/25.jpg)
25
Key broader policy issues
Integration of payer and provider: problematic in NHS context – creates monopoly
Integration and system reform – how to deal with PbR?
Nature of GP contract and incentives/opening up of primary care market
Governance and regulation issues
![Page 26: Naomi Fulop: What can the evidence tell us](https://reader033.vdocuments.us/reader033/viewer/2022052905/55840657d8b42af00a8b5027/html5/thumbnails/26.jpg)

What we still need to know [1]
Impact on patient experience Development of ‘markers’ for improved processes of
care required e.g. no. interactions between patients and professionals (i.e. is fragmentation reduced?)
Impact on use of services Impact on costs Impact on outcomes – needs careful thought
![Page 27: Naomi Fulop: What can the evidence tell us](https://reader033.vdocuments.us/reader033/viewer/2022052905/55840657d8b42af00a8b5027/html5/thumbnails/27.jpg)
27
What we still need to know [2]
Need to be clear about different components of integration and what is having an impact i.e. interventions needs to be well-described
Some of the evidence comes from ‘boutique’ experiments or pilots – how far can these be ‘mainstreamed’?
What needs to happen to ‘mainstream’?
