From legacy systems towards modern health information systems

Area of Science:

• Health Informatics
• Information Systems Engineering

Background:

• Legacy hospital information systems (HIS) often exhibit design weaknesses.
• Modern healthcare demands integration with new technologies like the internet and intranet.
• Evolving business conditions necessitate adaptable and updated HIS infrastructure.

Purpose of the Study:

• To describe a method for migrating legacy HIS to a modern HIS.
• To address the limitations of current systems and incorporate new technological requirements.
• To facilitate a gradual transition that accommodates emerging healthcare data standards.

Main Methods:

• A multilevel approach to data migration is proposed.
• The transition process is initiated with the doctor's workflow system.
• Focus on enabling gradual data transfer and integration of new standards.

Main Results:

• The initial phase of migrating the doctor's system yielded positive user feedback.
• The multilevel data approach appears effective for gradual system transition.
• Early results indicate the chosen migration strategy is on the right path.

Conclusions:

• The migration of legacy HIS to modern systems is a complex but necessary undertaking.
• A phased, multilevel data strategy is crucial for successful HIS modernization.
• Further solutions are required to manage the anticipated costs and timelines of HIS transition.
