6. Vision: Integrated Healthcare System
“What does it mean when we say our population will be older?
It means there will be more demand on healthcare because
older people are sick more often.
But this also means it is
a different pattern of healthcare
Picture taken from asiaone.com
So we have to respond to this by putting in more resources into
our hospital system, building new hospitals. “ And one key thing we must to
with this step-down care is
do
link up our acute hospitals […]
… get the whole system to be structured properly so that it will with community hospitals, so
be adapted to cater for the ageing population. To structure that you can have the best of
it properly means we need step-down care.” both worlds.

9. First Steps:
Electronic Medical Records Exchange (EMRX)
• Launched in April 2004
• Operating Principles
– Focus on improvement of patient care outcomes
• Other purposes such as research are secondary
– Living with Diversity
• Minimise impact on existing systems, lightest touch possible
• Standardise only where necessary
– Hybrid model
• Largely decentralised storage with some information
centralised
– Pragmatic & Incremental implementation
• Don’t aim for perfection
• Deploy quickly, learn and refine at next iteration
• Think BIG Start SMALL

Notes de l'éditeur
- small country, but big city- but even in this small place, we have great diversityAnd I think the greatest advantage that Singapore has is “It will be done”
As for the Health care services, - we have the full spectrum of health sectors: Primary, acute & intermediate, and Long term care. moreover, in each sector, the ownership is divided between numerous independent institutionsThusthe challesges for EA, What we have is quite a fragmented IT landscape - For example Multiple EMR systems in place at Hospitals, Polyclinics and Specialist Clinics , Minimal EMRs at GP and across Community Hospitals We have regional hospital partnering step down care institution,
At present, Singapore is organized into a 3 tiers pyramid With Tertiary Care be supported by the two local university, NUS, and Duke NUS..At the secondary care, each of the 4 zone, West, east, North and central will be anchored by a regional hospital, …A new model being employed in the recent time… 4 region….And finally at the Primary care , it is supported by Polyclinics, GPs, Community hospital and nursing home.This is where our jobs become interesting. For example, when KTPH was build, and under the new regional hub model, KTPH has a choice, and the path they choose is a mix from both cluster….And as we look across there are some interesting development… for example the paperless system uniquely developed….So as the healthcare eco-system and the model of care evolve, EA will face a bigger challenges with the 4 hubs continuous to evolve and the expected silver tsunami and still support the national driver to manage cost and information exchange between hospitals.
Singapore do have an over arching strategy going back to 2006, …
Adaptive Architecture – is this an oxymoron? Some will say that architecture does not adapt, technology does. However our experience is that architecting with an ‘ability to adapt’ mind set brings different principles to the fore that influences the nature of the final architecture deliverable.
We’ve introduced a passionate architecting style outside of the comfort zone of traditional enterprise architects. There is an art to mixing passion and architectural analytics skills to produce meaningful and credible results. The passionate style is also useful when engaging stakeholders, being able to vocalize and sell “the art of the possible” excites people, encouraging them to be involved and have a say.By it’s very nature innovation attracts risk. To address this we try to continue to evolve an environment that tolerates high risk, accepts the potential impacts of taking on risk and encourages brave decision making.
Our architecture team extends from one providing traditional architecting services into a more hybrid model that provides the skills needed to understand and create business transformation, innovation and strategy, and integrate them into architecture.
Our architecture team extends from one providing traditional architecting services into a more hybrid model that provides the skills needed to understand and create business transformation, innovation and strategy, and integrate them into architecture.
Our objective has been to provide meaningful supporting infrastructure and services that enable transformation and innovation.
The primary objective was never to develop a single, comprehensive target goal state – but to address future vulnerability and be adaptable to future requirements.
Solving Wicked ProblemsWe have entered a ‘VUCA’ world: Volatility, Uncertainty, Complexity and Ambiguity, and it’s becoming the norm for highly complex integrated eHealth programs. In response, we have actively established “problem solving” working groups, bringing together those who rise to the challenge of solving wicked problems.We strive to not only solve the EHR problem, but also consider the broader national connectivity, workflow and access problems that must be solved to enable true integrated health care.
Going forward we will continue to leverage on and extend the foundations delivered with NEHR phase 1. As I am presenting this, our teams in Singapore are planning future phases of NEHR implementation focusing on business intelligence, research, personalized healthcare and the extension of integrated care. Building a national information exchange capability that ensures access anywhere anytime in a flexible way to support changing models of care continues to be paramount.
We will be ‘brave’ going forward supporting innovative initiatives that make our clinicians lives easier, provide better outcomes for patients, continuously ensuring Singapore is at the forefront of eHealth.
