Summary
Singapore
Area of Science:
- Health Informatics
- Computer Science
Background:
- Singapore is implementing national e-health initiatives, notably the National Electronic Health Record (NEHR).
- Semantic interoperability is crucial for effective health data exchange.
Purpose of the Study:
- To describe the development and components of Singapore's Logical Information Model (LIM).
- To outline the approach for achieving semantic interoperability in Singapore's health information systems.
Main Methods:
- The Singapore LIM integrates international standards: ISO 13606-1, ISO 21090, and SNOMED CT.
- A logical design approach was employed to create interoperability artifacts.
- Mechanisms for unidirectional and bidirectional semantic interoperability were incorporated.
Main Results:
- A harmonized Logical Information Model (LIM) has been developed for Singapore's health records.
- The LIM effectively integrates international standards for data structure and terminology.
- The design approach facilitates the generation of interoperability artifacts.
Conclusions:
- The Singapore LIM is a key component for achieving semantic interoperability in national e-health initiatives.
- The model's foundation in international standards ensures a robust framework for health data exchange.
- The developed approach supports both unidirectional and bidirectional semantic interoperability.

01:29Issues And Trends In Healthcare Delivery System
The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.

01:20Integrated Healthcare System
An integrated healthcare system (IHS) is a set of organizations that provides for or arranges to provide coordinated and continuous service to a defined population. The IHS takes responsibility for that particular population's health status and outcome, both clinically and fiscally. An integrated healthcare system is a well-organized, well-coordinated, and collaborative network. The integrated delivery system is a network that connects different healthcare providers to deliver organized,...

01:26Methods Of Healthcare Delivery System
At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is limited...
