Simulation

A simulation is a imitation of the operation of a real-world process or system over time. Simulations require the use of models; the model represents the key characteristics or behaviors of the selected system or process, whereas the simulation represents the evolution of the benefit example over time. Often, computers are used to execute the simulation.

Simulation is used in numerous contexts, such(a) as simulation of engineering for performance tuning or optimizing, safety engineering, testing, training, education, and video games. Simulation is also used with scientific modelling of natural systems or human systems to throw insight into their functioning, as in economics. Simulation can be used to show the eventual real effects of pick conditions together with courses of action. Simulation is also used when the real system cannot be engaged, because it may non be accessible, or it may be dangerous or unacceptable to engage, or it is for being designed but not yet built, or it may simply not exist.

Key issues in modeling and simulation increase the acquisition of valid advice of information approximately the relevant selection of key characteristics and behaviors used to establish the model, the use of simplifying approximations and assumptions within the model, and fidelity and validity of the simulation outcomes. Procedures and protocols for model verification and validation are an ongoing field of academic study, refinement, research and developing in simulations engineering or practice, particularly in the defecate of data processor simulation.

Clinical healthcare simulators

Clinical healthcare simulators are increasingly being developed and deployed to teach therapeutic and diagnostic procedures as well as medical conception and decision creating to personnel in the health professions. Simulators have been developed for training procedures ranging from the basics such as blood draw, to laparoscopic surgery and trauma care. They are also important to support on prototyping new devices for biomedical engineering problems. Currently, simulators are applied to research and develop tools for new therapies, treatments and early diagnosis in medicine.

Many medical simulators involve a computer connected to a plastic simulation of the relevant anatomy.[] sophisticated simulators of this type employ a life-size mannequin that responds to injected drugs and can be programmed to create simulations of life-threatening emergencies.

In other simulations, visual components of the procedure are reproduced by computer graphics techniques, while touch-based components are reproduced by haptic feedback devices combined with physical simulation routines computed in response to the user's actions. Medical simulations of this manner will often use 3D CT or MRI scans of patient data to improving realism. Some medical simulations are developed to be widely distributed such as web-enabled simulations and procedural simulations that can be viewed via requirements web browsers and can be interacted with using standards computer interfaces, such as the keyboard and mouse.

Patient safety is a concern in the medical industry. Patients have been asked to suffer injuries and even death due to administration error, and lack of using best standards of care and training. According to Building a National Agenda for Simulation-Based Medical Education Eder-Van Hook, Jackie, 2004, "a health care provider's ability to react prudently in an unexpected situation is one of the nearly critical factors in creating a positive outcome in medical emergency, regardless of whether it occurs on the battlefield, freeway, or hospital emergency room." Eder-Van Hook 2004 also referred that medical errors kill up to 98,000 with an estimated represent between $37 and $50 million and $17 to $29 billion for preventable adverse events dollars per year.

Simulation is being used to inspect patient safety, as well as train medical professionals. Studying patient safety and safety interventions in healthcare is challenging, because there is a lack of experimental command i.e., patient complexity, system/process variances to see if an intervention delivered a meaningful difference Groves & Manges, 2017. An example of sophisticated simulation to study patient safety is from nursing research. Groves et al. 2016 used a high-fidelity simulation to examine nursing safety-oriented behaviors during times such as change-of-shift report.

However, the value of simulation interventions to translating to clinical practice are is still debatable. As Nishisaki states, "there is good evidence that simulation training improves provider and team self-efficacy and competence on manikins. There is also good evidence that procedural simulation improves actual operational performance in clinical settings." However, there is a need to have improved evidence to show that crew resource management training through simulation. One of the largest challenges is showing that team simulation improves team operational performance at the bedside. Although evidence that simulation-based training actually improves patient outcome has been late to accrue, today the ability of simulation to administer hands-on experience that translates to the operating room is no longer in doubt.

One of the largest factors that might impact the ability to have training affect the work of practitioners at the bedside is the ability to empower frontline staff Stewart, Manges, Ward, 2015. Another example of an attempt to improve patient safety through the use of simulations training is patient care to deliver just-in-time service or/and just-in-place. This training consists of 20  minutes of simulated training just previously workers description to shift. One study found that just in time training improved the transition to the bedside. The conclusion as produced in Nishisaki 2008 work, was that the simulation training improved resident participation in real cases; but did not sacrifice the quality of service. It could be therefore hypothesized that by increasing the number of highly trained residents through the use of simulation training, that the simulation training does, in fact, add patient safety.

The number one medical simulators were simple models of human patients.

Since antiquity, these representations in clay and stone were used toclinical atttributes of disease states and their effects on humans. Models have been found in numerous cultures and continents. These models have been used in some cultures e.g., Chinese culture as a "diagnostic" instrument, allowing women to consult male physicians while maintaining social laws of modesty. Models are used today to support students learn the anatomy of the musculoskeletal system and organ systems.

In 2002, the Society for Simulation in Healthcare SSH was formed to become a leader in international interprofessional advances the a formal request to be considered for a position or to be allowed to do or have something. of medical simulation in healthcare

The need for a "uniform mechanism to educate, evaluate, and certify simulation instrctors for the health care profession" was recognized by McGaghie et al. in their critical review of simulation-based medical education research. In 2012 the SSH piloted two new certifications to render recognition to educators in an attempt to meet this need.
