Simulator Training: The Future?

Mike Larvin

RCS Director of Education

Professor of Surgery

University of Nottingham at Derby

Imitation of reality for research, testing,

training or education

Requires:

• valid source information

• simplifying approximations and assumptions

• validity, reliability, fidelity

Simulation

Technological triggers: Cold war

“Tennis for Two” (1957) Higinbotham (Brookhaven)

used missile trajectories

Sputnik 1 (1957)Launched atop a modified

ballistic missile

• UG: less practical surgery

• PG1-2: foundation years

• PGY3-4: core MRCS

• PGY5-8+: specialty FRCS

• Less experience, WTD

• New technologies to learn

• Patients and trainees have changed

Surgical training has changed

• medical errors kill 98,000 people annually

• $37 to $50 billion for adverse events

• resident 80h week, less direct interaction

• bioterrorism threats and crisis management

Public drivers US IOM 2004

Generation ‘X’ = most of you

• Followed ‘baby boomer’ generation

• Born 1961 to 1981, ‘13th US generation’ - premarital sex, atheistic, republican, less respect for parents and authority - greater formal education

Generation X: Tales for an Accelerated CultureDouglas Coupland, 1991

• Followed ‘Generation X’

• Born early 1980s to mid-1990s - rapid communication, peer orientation, instant gratification, stimulating work - family breakdown, tech-savvy, ‘open’

Hunter-Gatherers of the Knowledge EconomyDavid Berreby, 1999

Generation ‘Y’ = junior trainees

• Followed ‘Generation Y’

• Born early mid-1990s to 2000s - baby boomlet - highly connected, lifelong use of comms and media technologies such as WWW - “digital natives”: instant messaging, texting, MP3, mobile phones, YouTube

Grown Up Digital: How the Net Generation is Changing Your WorldDon Tapscott 2009

Generation ‘Z’ = coming soon

Trainees still require:

• Knowledge

they prefer e-learning• Skills

technical, decisions, comms: like simulation• Structure

curriculum and assessment: online is fine

STEP® Foundation and Core

• MMC and ISCP competences

• MRCS preparation

• 8 A4 printed modules

• e-learning, video, web simulation

• e-community and college days

• anatomy, physiology, history, behaviour,

physical findings

• cadavers, prosections, plastinates

• plastics

• animal tissue

Active simulation

‘Human in the loop’ simulation

Ideal when:

• real environment too expensive or risky

• need to learn in "safe" environment

• test mistakes in safety-critical systems

• ‘type change’ after basic pilot training

Interactive simulation

• ‘live’: real people, simulated kit, real world

hi-fidelity, samples likely performance

• ‘virtual’: real people, simulated kit and world

VR training

• ‘constructive’: sim people, kit and world

behavioural training and assessment

Training simulation types

• Sim Man 3g (Laerdel)

• life-sized mannequin

• responds to injected drugs

• programmed for life

threatening emergencies

• can be changed ‘on the fly’

High-fidelity live simulation

• 1985, K Semm’s

‘pelvi-trainer’

for laparoscopy

• Haptics included

ἅπτεσθαι - to “contact” or “touch”

Laparoscopy

• visual components by computer graphics

• touch components by haptic feedback

• input/output: force feedback

could be widely distributed via standard

web browsers with standard game joysticks

Virtual simulators

• 2010: Symbionix

‘Laparotrainer’

for laparoscopy

• Haptics not included

Laparoscopy

• Largest capital project since post-war rebuilding

Teaching suite

Lower cost simulation

• improved health outcomes, reduced errors

• reduced health care costs, enhanced quality

• better skills, lower malpractice rates

• more flexible training at correct pace

• allows practice and mistakes, improves skills

without consequence to the patient

Benefits

• Despite their

proven effectiveness,

junior surgeons usually

have to pay to attend courses

from their own pocket

Donaldson, 2009

Costs

Simulator training: the future?

• More simulation, improved models

• Expensive, collaboration makes sense

• Preparation for work-based training

• NOT a substitute for the ‘real thing’

• More versatile than patient-based training

• Useful in standardising assessment
