THERP and SLIM for Human Reliability Assessment #HRA

I read about Technique for Human Error Rate Prediction (THERP) and Success Likelihood Index Method (SLIM) used for human reliability assessment (HRA).  These are technique used in other high reliability industries for: error identification, error quantification and error reduction.  Healthcare needs to learn from others to apply systems approach to reduce medical errors.

Engineering Amazing: Computer simulation can also help to transform the healthcare delivery

This is the next phase of medical simulation (2.0) for patient safety and quality care.  Modeling and Simulation is one of the most important systems engineering tools for analyzing complex systems.  It is also a prediction tool to estimate the performance of systems too complex for analytical solutions  or too expensive/danger to use “trial and error”.

Nuclear expert: After Japan, examine plants’ safety systems, not reactor design

From WSJ, The accident at the Fukushima Daiichi nuclear-power plant involved multiple system failures that cast doubt on the guiding principle of the nuclear power industry: that engineers can build enough redundancy into safety systems to overcome any threat.”

Aristotle’s words — “Probable impossibilities are to be preferred to improbable possibilities.” — should serve as a motto for engineers, reminding them to plan not just for rare events but also for contingencies that seem impossible.

Healthcare is in the process to transform the healthcare delivery, systems thinking is critical to deliver safety and quality care to patient every time and every day.

This is the key point from white paper Unmet Needs: Teaching Physicians to Provide Safe Patient Care published by Lucian Leape Institute at the National Patient Safety Foundation.

Re-Engineering to Create a Health Care System

Happy New Year !

Read post from ASU Healthcare Delivery and Policy Program and Healthcare Transformation Institute about the future of medicine. Along with other great programs from the county, Dartmouth Center for Health Care Delivery Science, Georgia Institute of Technology, Center for Operations Research in Medicine and HealthCare, Purdue University, Regenstrief Center for Healthcare Engineering, this new wave of system approach to address the quality and safety of healthcare delivery will have profound impact on medicine.   Looking forward to attend the coming 2011 IMSH meeting at New Orleans in two weeks and change ideas about how to expand the medical simulation beyond education.  The system integration using simulation has a great promise in the future to fundamentally change how the medicine is practiced.

Human Factors in Health Care

Just attend a meeting of Applying Human Factors in Health Care. Learned a lot from people from different perspectives: doctors, nurse, perfusionist, engineers, psychologists, etc. More and more people start to look this discipline on the impact of patient safety. There are several very interested questions discussed during the session: should all the cardiac surgeons using the same kind bypass tubing set to eliminate the potential human errors? Currently each hospital has its own customized tubing set. How should we design the system to help eliminate the potential human errors? How to find the balance between healthcare process standardization and provider’s own preference? How to use the simulation center as an institutional laboratory for quality safety experiment? Also found very good reviews of this topic by BMJ and University of Wisconsin.

Building a Better Delivery System: A New Engineering/Health Care Partnership

National Academy of Engineering and the Institute of Medicine published this book emphasized the need for two disciplines working together to address the health care and patient safety issues.
