The Future of Emergency Medicine Jonathon M. Sullivan MD, PhD Wayne State University Detroit Receiving Hospital
Purpose of this Lecture • Put away your pencils, class • This won’t be on the test • Raina Burke wouldn’t stop bugging me • Sullydog just wants to have fun • Some of us might actually learn something
Outline • Science fiction vs. futurism • How futurism (doesn’t) work • Identifying trends: • Technological trends • Sociological and demographic trends • Economic and political trends • Global trends (megatrends) • Summary (how I failed to predict the future)
Science Fiction vs. Futurism • “The difference between fiction and reality? Fiction has to make sense.” –Stephen King
Futurism • Historical antecedents • 19th century Comte's discussion of the metapatterns of social change • Early 20th century systems science in academia, • National economic and political planning: • France • Soviet Union and Eastern bloc countries. • Emerged as an academic discipline after WWII
Futurism • Two broad approaches: • American: “Quaterly Report/Bottom Line” mentality • applied projects • quantitative tools • systems analysis • analysis of complex, large scale systems and the interactions within those systems. • Identification of units, processes and structuresgame theory analysis and modeling—signficant $$$ apps • European: “What about our Great-Grandkids?” mentality • more speculative and interested in long-term future of humanity, planetary systems, etc • Increasing crossover
Futurism • An increasingly dismal science • Wild cards (Asimov’s Mule) • Butterfly effects (chaos theory) • Uncooperative markets • Uncooperative societies and electorates • Self-organizing systems • Singularities – point at which f(x) = ∞; also describes historical or technological discontinuities: • Advent of agriculture • Printing press • Internet • 9-11 • War, Famine, Plague, Bush • The odd asteroid
Futurism • Anticipatory thinking (futures) • Causal layered analysis (CLA) • Environmental scanning • Scenario method • Delphi method • Future history • Monitoring • Backcasting (eco-history) • Back-view mirror analysis • Cross-impact analysis • Futures workshops • Failure mode and effects analysis • Futures biographies • Futures wheel • Relevance tree • Simulation and modelling • Social network analysis • Systems engineering • Thinklets • Visioning • Trend analysis • Morphological analysis • Technology forecasting If you can’t dazzle ‘em with prophecy….
Futurism • The Delphi Method • An explicit approach developed by the Rand corporation for Defense/Strategic planning • Utilizes panels or pools of experts • Highly rigid methodology and information flow • Lousy track record

Enough CYA, Dog • Step One In This Fool’s Errand: • Identify Trends: • Technological trends • Sociological and demographic trends • Economic and political trends • Global trends (megatrends)
Technological Trends • Information Technologies • Artificial Life, Genetic Algorithms, Cellular Automata • Molecular biology, proteomics, computational protein folding • Artificial organs • Medical imaging • Materials science and nanotechnology • Drug delivery technologies for deep organ and organ-spec txs • Point-of-care testing • Resuscitative adjunts
Technological Trends: IT • More than just data storage and collection • Increasing penetration into EM is manifest • Pros: efficiency, safety, info availability • Cons: info overload, privacy concerns, infrastructure vulnerability • Important sub-trends: • Decreasing processor size • Moore’s law • Wireless networks • HIPAA considerations, security issues • Neural networks, diagnostic algorithms
Technological Trends: IT • Question: does more information = better care? • Available evidence casts grave doubt on such a presumption • Swan-Ganz Catheters • Question: does increased information increase the resolution of the retrospectoscope?
Tech Trends: ITInformation vs. Exformation • As disorder in a system increases: • The entropy of the system • increases • the amount of information “encoded” in the system • increases
Work Tech Trends: ITInformation vs. Exformation Information Entropy ↑ Work “Value Added”
Tech Trends: ITAccelerating Acceleration • Kurzweil: • Human technological progress tends to accelerate over the course of history • IT accelerates the rate of acceleration of technological progress • Have we passed the singularity? • 20 years ago, could we have predicted: • Internet porn, PDAs, MyYahoo!, the Y2K scare, SETI@home, CIS, genetic algorithms? • 10 or so years ago we actually DID predict: • The Internet would make everything perfect forever • email, dial-ups and Yahoo! would free China and N. Korea • Less paperwork for everybody! Yipee! • A sudden return to neolithic civilization at midnight, 12-31-1999 • (Cruz told me he was dissappointed when it didn’t happen) • A better informed public and more honest politicians • The Internet was going to change EVERYTHING! • Network evolution: emergent and unpredictable
Trends: IT Oppos.

All done. Back to patient care!
Trends: Bioimaging • Ultrasound • More compact: every doc with a unit • enhanced resolution • contrast materials • expanded utilization by EPs • Continued evolution of computed tomography • MRI • Magnetic resonance spectroscopy—more info about chemical and physical properties of a region than MRI • Multinuclear imaging—tweak nuclei other than H • Internal imaging
