The 21st-Century Health Care Systems
• Quality as a system feature.
• Goals: safety, effectiveness, patient-centeredness, timeliness, efficiency, quality and equity.
• Three guiding strategies: patient-centered, knowledge-based, and careflow-based systems.

Knowledge Management
The goal of KM is to improve organizational performance by enabling individuals to capture, share, and apply their collective knowledge to make optimal decisions ….. in real time, that is to take actions that will affect the outcomes.

Do we want to build, pay for, and maintain Information systems
without having Informatics Standards?

Two things about the future …

time
Technological change & advances
present
predictions
Regarding change and technological advances … we tend to over-estimate them in the short-term & under-estimate them in the longer-term
![Page 16: Healthcare needs information systems ! ICTExpo 2005 Do more with less William Grimson 14 th April 2005.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649ebc5503460f94bc4d63/html5/thumbnails/16.jpg)
Life cycle costs
• Full life cycle costs need to be considered as well as all the risks over that period
• For cost containment it is essential that alternatives are considered … i.e. looking well into the future to assess impacts and hence inform current decision-making

we need a vision, we need to plan, we need to have a rational
approach …and we need Standards?
![Page 19: Healthcare needs information systems ! ICTExpo 2005 Do more with less William Grimson 14 th April 2005.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649ebc5503460f94bc4d63/html5/thumbnails/19.jpg)
Addressing the Issues
• Information role of the Health Information and Quality Authority (HIQA)
• Information access and governance• Information standards• Information deficits and developments• The Electronic Healthcare Record• ICT• Information and service planning
![Page 20: Healthcare needs information systems ! ICTExpo 2005 Do more with less William Grimson 14 th April 2005.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649ebc5503460f94bc4d63/html5/thumbnails/20.jpg)
Information Standards (HIQA)
• National Health Information Standards Framework (Action 19)– Data standards– Technical standards– Quality standards
• Indicator standards (Action 20)• Quality assurance of information to public
(Action 21)
![Page 21: Healthcare needs information systems ! ICTExpo 2005 Do more with less William Grimson 14 th April 2005.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649ebc5503460f94bc4d63/html5/thumbnails/21.jpg)
The Electronic Healthcare Record (HIQA)
• EHRs will be implemented on a phased basis (Action 15)– Defined and adopted through inclusive process– Implementation sites with supporting ICT
infrastructure– National roll-out in line with multi-annual ICT action
plan
![Page 22: Healthcare needs information systems ! ICTExpo 2005 Do more with less William Grimson 14 th April 2005.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649ebc5503460f94bc4d63/html5/thumbnails/22.jpg)
ICT (HIQA)
Multi-annual ICT action plan (Action 22)– Build on work of HeBe plan– Develop in cooperation with HSE and DoHC– Ensure standard approach and VFM– Support national solutions (eg SAPS,PPARS)– Enable fast and secure communications infrastructure through
VPN– Support and enable eHealth applications and development of
Electronic Healthcare Records (EHRs)– Address digital divide
![Page 23: Healthcare needs information systems ! ICTExpo 2005 Do more with less William Grimson 14 th April 2005.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649ebc5503460f94bc4d63/html5/thumbnails/23.jpg)
The Pace of Progress
It is important to note that many of the critical actions in the Strategy will be achievable through relatively modest new investment. Examples include improved use of existing information and introduction of governance framework…..Other initiatives are more heavily dependent upon investment decisions and the overall pace of new developments in the wider health system…These include investment in major ICT solutions… However, it is clear that ongoing consultation and partnership with all stakeholders will be of central importance to the implementation process throughout. (NHIS, Chapter 16, Implementation Phases)

Standards authorities
![Page 25: Healthcare needs information systems ! ICTExpo 2005 Do more with less William Grimson 14 th April 2005.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649ebc5503460f94bc4d63/html5/thumbnails/25.jpg)
National Standards Authority of Ireland (NSAI)- HISC
To contribute to the development of European or International standards for patient and hospital information systems, specifically through participation in the work of CEN TC 251, ISO TC 215, and HL7; and to advise NSAI in regard to the need for National standards in this area.
![Page 26: Healthcare needs information systems ! ICTExpo 2005 Do more with less William Grimson 14 th April 2005.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649ebc5503460f94bc4d63/html5/thumbnails/26.jpg)
National Standards Authority of Ireland (NSAI)- HISC
More specifically the role of HISC is to: 1. Increase awareness of the role and purpose of Health Informatics Standards in the overall delivery of healthcare in Ireland. 2. To provide a mechanism by which Ireland is represented at appropriate Standards organisations and activities.3. To act as a conduit to bring back information and assess the impact of future requirements and regulations on the Irish situation.
