What is Health Services and Systems Research?

Welcome to the Signature Program in Health Services and Systems Research (HSSR) at Duke-NUS Medical School.
 
HSSR is established as a center of academic excellence for research and education on the organization, funding, and delivery of health services. Our focus is on public health and clinical service innovation in an increasingly complex and connected world.
 
HSSR employs a systems perspective to addressing critical health issues. Systems thinking cuts across all of our research priorities and recognizes the multiple leverage points and feedback loops involved. This includes health, social, economic, political, biological and other systems. Our core funding and mission requires us to conduct research that benefits Singapore. However, we also undertake related regional and international work that is consistent with Duke’s global health mission.

Latest initiative to support improved health outcomes in Asia launched
The IMS Institute for Healthcare Informatics has launched a new branch focused on supporting improved health outcomes across Asia. Duke-NUS Medical School is one of its collaborative partners.

 

Based in Singapore, the team leverages institutions from the public and private sector - a move supported by Economic Development Board (EDB) Singapore. “The shift from product-centric to patient-centric healthcare requires collaborative innovation between government, health professionals and businesses. Effective solutions to key healthcare challenges will have to incorporate data-driven insights, new technologies, and appropriate business models,” said Ms Ho Weng Si, director, Biomedical Sciences. “EDB welcomes IMS Institute Asia’s decision to co-innovate with partners in Singapore to accelerate healthcare transformation in Asia.”

 

In Asia, the IMS Institute activities will focus on three areas:

  • Mobilizing and advancing health services and systems research: The Institute will bring together leading policy advisors, educators, researchers and medical care providers to initiate research activities and apply evidence-based approaches to address key healthcare issues.
  • Developing new insights on disease burden in Asia: The Institute will connect clinical, economic and patient-reported outcomes data to provide all stakeholders with deeper insights for improving the care of patients and their treatment journey experience.
  • Advancing decision analytics in clinical practice and public policymaking: The Institute will support efforts by academia, clinicians, health administrators and policymakers to use real-world, data-driven decision analytics for more informed decision making and improved healthcare costs and outcomes.

In addition to Duke-NUS, the IMS Institute in Asia is collaborating with the National Cancer Centre Singapore, National University Hospital and InvitroCue Limited.

Public Lecture by Professor Mark S. Roberts on 'What does the value of modern medicine say about the $50,000 per QALY Threshold?'
The public lecture was held on 5 September 2016. This lecture was an evaluation of the value of modern medicine. There is an almost mythical value of $50,000 per quality-adjusted life year that is felt to be the level at which an intervention is “cost effective”. The origins of this number, and its validity was examined in the context of health care choices that can be observed in society. Click here to read more about Prof Roberts's presentation.
        

Public Lecture by Associate Professor Shalini Kulasingam on 'Combining decision modeling and epidemiologic studies to determine optimal cervical cancer control policies in the era of HPV vaccines'                      

The public lecture was held on 22 August 2016. In the lecture, Dr Shalini used a combination of modelling and epidemiology to illustrate predicted changes to cervical cancer in the era of HPV vaccines.

Public Lecture by Dr Akihiro Nishi on 'Social Inequality, Health, & Experimental Social Science'

The public lecture was held on 1 March 2016. Health inequality has been one of the most important topics in social science and medicine. In the lecture, Dr Nishi covered the general background of social inequality in health. He also presented his recent experimental work on visibility of wealth inequality at dynamic social networks (Nishi et al, 2015, Nature). He also discussed the future direction of experimental social science and its application into public health and health services research.                                                                              

 

Public Lecture by Dr Masayoshi Oka on 'Neighborhoods and Health: Concepts, Methods and Applications'

The public lecture was held on 6 October 2015.  The current state of knowledge about neighborhoods and their links to health encourages us to think that “where we live” matters to our health over and above “who we are.” A growing number of studies have demonstrated the associations of neighborhood physical and/or social characteristics with various health behaviors and health outcomes after accounting for individual socio-demographic characteristics (e.g., age, gender, race/ethnicity, income level, educational attainment, and/or employment status). In other words, the place of residence may either be beneficial or detrimental to our health. Hence, ignoring the possible role of neighborhoods may lead to an incomplete understanding of the determinants of health, and thus result in developing ineffective prevention and health promotion strategies. Dr Oka presented an interdisciplinary approach to the study of neighborhood effects on health. 

 
Public Lecture by Dr Sorapop Kiatpongsan on 'Spreading the Wealth and Health(care)'
The public lecture was held on 9 September 2015. The speaker shared findings from his recent publication and ongoing research on economic and health inequalities. His studies show how much people think CEOs and cabinet ministers should be paid and how people think the government should allocate healthcare spending to the rich and poor.
