Introduction
The Ministry of Health (MOH) believes in ensuring quality and affordable basic medical services for all. Singapore’s healthcare system is designed to ensure that everyone has access to different levels of healthcare in a timely, cost-effective and seamless manner.
Despite the efforts mentioned above, there are growing signs of unequal wealth distribution in Singapore. Our project seeks to test out whether the same level of healthcare accessibility is provided to all planning areas in Singapore despite this phenomenon. This inquiry is supported by various data visualization, statistical and predictive techniques to arrive at a conclusion.
Background
Overview of Singapore's Healthcare Landscape
Singapore is one of the most developed state in Asia and the world (as measured by GDP per capita). Its healthcare spending per capita is one of the highest in Asia and the world, which means that the majority of the population is likely to enjoy good quality healthcare. This can be largely attributed to the core philosophy of the MOH's beliefs in ensuring quality and affordable basic medical services to all.
Singapore’s healthcare system is designed to ensure that everyone has access to different levels of healthcare in a timely, cost-effective and seamless manner. The key policies enabling this includes:
- Improving access to healthcare in the community: Increase acute beds by 1,700 and community hospital beds to 3,000 by 2020, Investment in primary care infrastructure (polyclinics, community health centres)
- Enhancing key enablers including technology and manpower: Adding 30,000 more healthcare workers by 2020 and adopting digital technologies such as AI
- Strong financing policies to ensure healthcare costs remain affordable to the masses. This includes policy packages like the Pioneer Generation Package (subsidies for elderly medical care), MediShield Life (universal insurance coverage) and the Community Health Assistance Scheme (means-tested subsidies on primary care).
Motivation
Despite these efforts, there are growing signs of unequal wealth distribution in Singapore. We intend to test out whether healthcare access is provided to all planning areas in Singapore despite differences in income levels (per planning are) and also whether there is appropriate healthcare coverage for the ageing population.
Objective
To assess the status of Singapore’s accessibility to healthcare based whether the existing healthcare facilities and social support meets the demands of the poorer income groups and ageing population. Based on the results, we hope to conclude that either (a): There is no significant difference in accessibility despite geographical differences in income and age groups across the island or (b): there is significant difference in accessibility correlating to geographical differences in income and age groups across the island.
Visual Data Exploratory
- Develop a visual layout of Singapore’s wealth distribution (monthly household income) on a geospatial basis
- Layer on age distribution across the planning areas
- Develop a visual layout of Singapore’s healthcare network (primary, tertiary, community, aged homes) on a geospatial basis
- Explore mapping over elderly friendly zones / wheelchair friendly zones that allow elderly access to nearest healthcare facilities
- Explore availability of further social support including but not limited to Family Service Centres, Resident Centres.
- To highlight primary care facilities with lower income social support such as CHAS, PG etc.
Interactive Visualisation Result
From policymaker point of view:
- oversight of healthcare and social support demand vs. healthcare supply and facilities
- able to pinpoint locations whereby there may be healthcare accessibility gaps
From everyday Singaporean point of view:
- overview of all healthcare facilities providing all levels of care
- able to toggle to the nearest healthcare facility
- able to view the social support provided in the planning area
