“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

So we have to respond to this by putting in more resources into our hospital system, building new hospitals.

… get the whole system to be structured properly so that it will be adapted to cater for the ageing population. To structureit properly means we need step-down care.”

Picture taken from asiaone.com

And one key thing we must do with this step-down care is to link up our acute hospitals […] with community hospitals, so that you can have the best of both worlds. Prime Minister Lee Hsien LoongNational Day Rally 2009

Reference Architecture example: Goal State EMR

A conceptual goal state EMR system has been modeled to add context to the application architecture and integration pattern.

The conceptual goal state EMR’s capabilities are:

• Integration

• Clinical data sharing

• Reconciliation
