Why Don’t Information Industries Make a Greater Impact on Care Delivery?

Dr. Terry Young , Professor of Healthcare Systems, School of Information Systems, Computing and Mathematics, Brunel University

He and Dr. James Fackler published a paper  Why healthcare professionals are slow to adopt modeling and simulation?  to explore the reason for slow adoption of the computer modeling and simulation in healthcare.

Professo Young is also the co-founder of the Cumberland Initiative, a network of leading clinicians, managers, modellers, academics and industry specialists who are pioneering the modeling and simulation approach in the NHS. Lord Norman Warner, former Health Minister for NHS reform said in a press conference. 

“We will only do something different if we have an analytical base to enable people to change,” argued Lord Warner. “The problem in the NHS is, unless local people are confronted with overwhelming evidence that something has to be done and there is another way, in many places they don’t change their institutional behaviour.” 

The NHS is a very conservative organisation in many places. But where we are now, we badly need the kind of initiative that Cumberland is showing. The traditional thing you do is try and gee up doctors and managers but we need a bit of an injection of data collection and analysis.”

Learn from operation research to apply simulation tools for systems and organizational changes in healthcare

Looking forward to learn from #informs2013 to unleashing the promise of #simulation for healthcare transformation though systems modeling & simulation.  Society of Simulation in Healthcare, world largest multidisciplinary and multispecialty organization, seeks to improve performance and reduce errors in patient care through the use of various simulation modalities.  The main purpose of simulation application in healthcare include:  education, assessment, research and healthcare system integration.   Recently,  we established  Healthcare Systems Modeling & Simulation Affinity Group for those who are  interested of  systems integration.

Our mission : Develop and use modeling and computer simulation resources with a systems engineering-based approach to design and evaluate (system) solutions that will improve patient safety, quality of care, and cost effectiveness in healthcare.

Please fill out the survey if you are interest to join our group.  We also have a LinkedIn group for discussions and sharing ideas.    I am looking forward to learn more from you.  Thank you !


“A Systems Approach to Improve Bedside Patient Rescue (BPR) on Hospital Floor ” presentation at INFORMS Healthcare 2013

Xiaolei Xie presented our work at INFORMS Healthcare 2013 Conference 

A Systems Approach to Improve Bedside Patient Rescue (BPR) on Hospital Floor 

Xiaolei Xie, Yue Dong, Jeanne Huddleston, Jingshan Li, Thomas Rohleder, Colleen Swartz

Abstract: In this paper, a systems approach is presented to improve operations related to bedside patient rescue (BPR) process. A five-module (triage, patient, floor, RRT and ICU) framework is proposed to systematically study the correlations and interactions among all the factors related to BPR. Under this framework, simulation model using ARENA has been developed, which provides a quantitative tool for medical professionals to improve BPR process.

INFORMS Healthcare 2013

I am at Chicago to attend the second INFORMS conference on healthcare operations research, systems engineering and analytics. INFORMS HEALTHCARE 2013.  The Institute of Operations Research and Management Science (INFORMS) is largest professional society in the world for professionals in the field of operations research (O.R.), management science, and analytics.

Computer simulation has been purposed as a “third branch of science beyond experimentation and theory” published in Science  1992. It is one of most common systems engineering tool for process analysis and system optimization by many industries including those high reliability industries (aviation, nuclear power stations, etc.).  Most recent review about Computer Simulations in Science can be found from  Winsberg, Eric, “Computer Simulations in Science”, The Stanford Encyclopedia of Philosophy (Summer 2013 Edition), Edward N. Zalta (ed.)

Healthcare application of computer simulation can be found from listed papers below

SSH Systems Engineering based Simulation Affinity Group

Happy New Year! IMSH 2013 is coming up in less than two weeks, and I look forward to seeing everyone in Orlando.Many SSH members have a special interest in using various simulation tools (computer simulation, mannequins, etc.) to study the interactions between three major entities of the healthcare delivery system (and sub-systems): patients, providers, and processes.

A few years ago, I started to think about what is the connection between various simulation tools and its application to study complex systems after I read Dr. Stephen Small’s paper Simulation Applications for Human Factors and Systems Evaluation”  With an opportunity to learn from a Professor of Industrial Engineering (Dr. Huitian Lu) , I started using computer modeling to define, measure and analyze the complexities of a healthcare setting. So far, my simulation projects have been primarily focused on using systems engineering approach and computer modeling and simulation for (ICU care) process improvement in the complex healthcare delivery System of Systems.

This is also one of the key applications of simulation that has great potential to transform healthcare delivery. I know many of you have done amazing work related to this area. But we don’t yet have a formal group to discuss this topic in IMSH. So I decided to create the “System Engineering based Simulation Affinity Group” and invite you to join me to learn and share each other’s work and then disseminate the knowledge to the SSH community and beyond.

The inaugural meeting of this affinity group will take place at IMSH 2013 in Orlando. The time and location has been set as follows:

  • Date: Sunday, January 27, 2013
  • Time: 5:00 PM – 6:00 PM
  • Room Location: Peabody Hotel Columbia 37

Please consider joining this event. Feel free to invite others who might be interested in this topic.

Please let me know you have any comments or suggestions. Thank you for your consideration! See you soon in Orlando.

“In Praise of Fresh Air” and Medical Simulation 2.0

Finished the #IMSH2012  this Wednesday Feb 1. On my way home, ads inside newspaper did got my attention and inspiration.  That was the new brand and logo promotion from J.C. Penney by Ron Johnson (previous Apple executive) (Disclosure,  I don’t have  personal financial conflict of interest).  The key message is ” In praise of fresh air”.  The IMSH2012 draw near 3000 people around the world.   Beyond the fresh air we had at San Diego, I had chance to talk old and new friends.  Their insights made me thinking: What is the next 10 years for medical simulation community?
