health care and population development
“Population ageing is unprecedented, a process
without parallel in the history of humanity. … At the
world level, the number of older persons [persons
aged 60 years or over] is expected to exceed the
number of children [persons under age 15] for the
first time in 2045. … Population ageing … is
affecting nearly all the countries of the world.”

Affairs, Population Division. World population ageing 2009.

health care and population development
“In 2000, the population aged 60 years or over
numbered 600 million, triple the number present in
1950. In 2009, the number of older persons had
surpassed 700 million. By 2050, 2 billion older
persons are projected to be alive, implying that
their number will once again triple over a span of
50 years.”

some lessons learned (2)
• activities of persons (also) at home are increasingly getting correlated to health care
• developments on ambient assisted living and smart homes, not considering this, may be limited
• developments in health care (diagnostics, therapy, financing, …), not considering this, may be limited
• basic research is needed in many fields
• early translational activities and joint projects with those institutions, providing technology and services is needed

on HET Reinhold Haux 36
some lessons learned (3) – HET
• in the sensor-enhanced environment ‘classical’ standards for the electronic health records have limits
• analysing (e.g. acceleration) sensors for e.g. fall risk prediction is getting advanced and methodology from signal processing can well be used
• existing methods for analysing data from multiple different sources are not yet satisfactory
• in addition to data protection and privacy issues, legal matters on such sensor systems as ‘medical products’ have to be solved
• considerable research is still needed for appropriately connecting homes (and home-based services) to those of hospitals, …

on HET Reinhold Haux 37
some lessons learned (4) – (sensor-enhanced) HIS
• although the need for collaboration of health care organizations is unanimously seen, the organizational framework is still fragile
• also, some services needed, do not fit well to a certain institution
-> foundation of the Lower Saxony Bank of Health
• information management concerning multiple independent organization is different
• HIS architectures can well benefit from IHE approaches, which are meanwhile in practise and are able to consider existing “legacy systems”
• education of craftsmen and other professions involved in the context of home care is crucial

(also) through HET...
• ... a person's living environment will become the future place

• ... new diagnostic and therapeutic opportinities exist for
many clinical disciplines
• ... save(‘intelligent‘) living/ AAL, medical and nursing care
