Junior doctor posts may be scrapped in favour of nurse jobs as the Department of Health reorganises training for healthcare professionals

A briefing document by NHS Employers outlines Department of Health proposals to cut central funding given to hospitals to cover the base salaries of junior doctors.

At present 100 per cent of a first year junior doctor’s base salary (£23,000) is funded by the DH in recognition of the fact that they require almost constant supervision and training.

But under proposals circulated to teaching hospitals last week, only 80 per cent would be covered.

Funding to cover the salaries of junior doctors in their specialty training years would be drastically cut from 100 per cent for years three and four to 40 per cent and 25 per cent respectively. The changes mean hospital trusts would have to make up the rest of the salaries themselves.

The changes are being made to free up funding to better fund training places for nurses, midwives and all other healthcare professionals.

Discussions on the changes to the way clinical training is funded are being led by Medical Education England, which was set up after the 2007 debacle over junior doctor training posts when the new Medical Training Application Service was introduced.

A source close to Medical Education England said there were now concerns the proposals could “tip the balance” for some trusts, as they drop training posts for some specialties or dispense with junior doctors altogether.

A £15 set of electrodes could help doctors read a patient's mind during a general anaesthetic.

Not only will this ensure the patient is properly anaesthetised, but because doctors will be able to monitor the effect of the anaesthesia more accurately, this will reduce dosages, so patients will wake up less woozy, and cut the risk of overdose.

The pioneering device, known as cerebral function monitoring (CFM), means doctors can assess anaesthetic levels accurately first off - ensuring the patient remains asleep throughout the operation.

During the procedure, three silver electrodes are taped to the patient's forehead - these continually monitor brain function, relaying information back to the anaesthetic machine and a monitor. The new system helps the anaesthetist maintain regular brain signals, ensuring the anaesthetic is working effectively.

“This is incredibly exciting,” says Dr David Coates, consultant anaesthetist at Spire Hospital Bristol and Bristol Royal Infirmary, who has used CFM regularly and successfully.

“It allows constant finetuning of the amount of anaesthetic being delivered in a way we've never been able to do before.”

Reports from the department of anaesthesiology, Banaras Hindu University show there is an acute shortage of anaesthetists in India.

Dr Mathur, who is the general secretary of Indian Society of Anaesthesiologists (ISA), Varanasi Branch said that demand for fully trained and qualified anaesthesiologists in the country is ever increasing, he also emphasised the need for growing public awareness about recent advances in the field.

“One needs to understand that role of trained anaesthesiologists has diversified in recent years, and they are taking care of a number of super specialty health care services, especially the post-operative treatment of critical patients” he said. “Now, they offer services in various multi-speciality areas including neuro, paediatric and cardiac anaesthesia besides pain and palliative services to relieve pain of critically ill patients.”

However, his concern for shortage of trained anaesthesiologists in the region was also evident, as he indicated that the scarcity is leading to a situation, where critical cases are being handled by untrained staffs, inadequate to handle such emergency situation.

“These days anaesthesiolists are handling delicate health services like cardio-vascular and cardio-respiratory resuscitation and these services demand adequate training and pin point accuracy to read the situation. Similarly, other critical care services like ozone therapy also need training” Dr Mathur added.

Setting targets for NHS performance failed to win over the ‘hearts and minds’ of NHS staff, health secretary Andy Burnham has admitted.

Speaking to the Urban Institute think tank before a meeting with President Obama’s health taskforce, health secretary Andy Burnham said he understood why staff thought the drives signalled a lack of trust on the part of central Government.

But he also insisted that Labour had been right to introduce targets when it first came to power.

“Targets drove the system hard and were the right thing to do,” he said.

“Looking back now, I can see that the emphasis began to imply a lack of trust in staff at the frontline that became disempowering.”

Labour has been fiercely criticised for introducing what many view as an overwhelming number of targets, with patients groups suggesting the practice has caused less well-known issues to be ignored.

Mr Burnham said many of the targets would be scrapped over the coming months, but added that the 18-week operation guarantee would remain in place, as would the aim to see all patients entering A&E within four hours.

Swine flu may create a shortage of intensive-care unit beds for U.K. children, leaving medical professionals struggling to cope in the pandemic, according to a report in today’s Archives of Disease in Childhood.

Doctors at Cambridge University and Addenbrooke’s Hospital estimated that 3.8 percent of under-15s hospitalized with swine flu in the U.K. will require intensive care. If just 2 percent of children who contract the illness require hospitalization, almost all of the U.K.’s available 303 pediatric ICU beds in 25 centers will be occupied, according to the findings. If 1 percent is hospitalized, half of the existing capacity will be filled, the researchers said.

“It appears inevitable that pediatric ICUs will experience significant additional pressure this winter from admissions due to the pandemic,” the authors, led by Ari Ercole of the Cambridge University Department of Anaesthesia, wrote in the journal.

The shortages may be more acute in some regions because the provision of ICU beds varies around the country, the researchers wrote. Hospitals in London, Yorkshire and the Humber and the Northeast are well equipped with pediatric ICU beds, while those in Wales, the southeast coast and east of England are not as well served, according to the report.

In October NICE said the National Health Service would save 600 million pounds per year if certain guidance was adhered to, and highlighted the relevant documents within which the claimed savings lay.

In a statement on its website, the cost-effectiveness body said it was publishing a range of recommendations pulled from its guidance which would benefit the NHS in "challenging" financial times, if they were adhered to.

NICE said over its 10-year existence, it had made 150 recommendations which could save the NHS money, either in direct cash terms or by using resources more effectively elsewhere.

The highlighted guidance included measures that entailed both spending money now to save spending more in the future and cutting ineffective treatments. It includes several which have a potential effect on drug use.

Giving very brief details of its reasoning with references to the full guidance, NICE said in the case of hypertension, its update recommended greater use of drugs to control the condition.

"Following the revised recommendations will cost more in drugs, but this is far outweighed by the predicted number of cardiovascular events that will be avoided if hypertension is better controlled," it said.

NICE's leaders, Andrew Dillon and Mike Rawlins had previously come under pressure from members of parliament investigating NHS spending for not finding enough procedures that the health service could simply stop carrying out to save money.

Up To 60% Of Patients With Chronic Pain Who Do Not Respond To Pharmacological Therapy Improve With Surgical Operations
Surgical operations for treating chronic pain may ameliorate symptoms and enhance the quality of life of up to 60% of patients that do not respond to therapy with pharmacological drugs. This was a conclusion drawn from the results gathered by specialists of the Pain Unit of the University Hospital of Navarra at the XV Annual Reunion of the European Society of Regional Anaesthesia and Pain Therapy (ESRA).

Organised in Pamplona by the Pain Unit of the University Hospital, the symposium brought together more than 600 specialists from all over the world in order to deal with the latest advances in the field of regional anaesthesia and pain therapy. This year’s meeting of ESRA brought together the greatest ever number of participants with a total of 241 scientific works presented in poster and video formats.

Combination of pharmacological treatment and surgery
Pain units have two approaches for treating chronic pain. On the one hand, therapy with pharmacological drugs, which include various medications such as analgesics, anti-inflammatory drugs, anti-epileptic drugs, anti-depressives, muscle-relaxing agents, opioids and opiate derivatives. The other focus involves minimally invasive surgical techniques. The combination of both treatments considerably enhances the therapeutic success of the persistent chronic pain.

Amongst the surgical techniques is the epidural approach with local locales anaesthetics and corticoids being administered for the treatment of lumbago and radicular pain, i.e. those pains produced in the nerve roots. The treatment of radicular lumbar pain, applied with central infiltrations — epidural via the transforaminal route — can obviate surgery in 60% of the patients, at the same time the percentage of these see their process of recovery accelerated in the context of acute pain.

Neuro-stimulation of the medulla: more than 70% with improvement
Another example of treatment applied at the University Hospital of Navarra is the group of techniques known as neuromodulation, amongst which is that of radiofrequency, involving the application of an electromagnetic field to the nervous tissue in order to annul the pain passing through the corresponding channels. In the case of neuropathic pain, the radiofrequency achieves long-term benefits spanning 35% to 70% of patients, according to the pathology being treated.

Likewise, at the ESRA Reunion specialists from the Pain Unit at the University Hospital provided data of the results obtained through neurostimulation of the medulla. With this technique an electric field is applied to channels that modulate or regulate transmission of pain with the goal of triggering a short circuit in this transmission in order to interrupt it. Percentages of enhancement obtained reach 90% of patients with migraines, 80% with vascular pain, 70% with neuropathic pain and 55% with lumbar pathologies.

Within the minimally invasive surgical techniques, there are other ways of periferally stimulating the nerve roots; iontophoresis, involving the administration of ionised medication through the dermis; and the administration of ionised medication through the intratecal route, i.e. within the space that surrounds the medulla, thus enabling greater efficacy and fewer side effects with reduced doses.

Advantages of the multidisciplinary approach to pain
The multidisciplinary approach to chronic pain has several advantages. Combining pharmacological treatment with minimally invasive surgical techniques, the final result is reached earlier and with enhanced efficacy. Moreover, greater patient satisfaction is achieved, as clinical improvement is earlier, return to work is earlier, as the re-incorporation to social and family life. Besides, this multidisciplinary approach reduces costs in health terms, avoiding patients having to go from one specialist to the other until finding a solution to their pain. On the contrary, at the Pain Unit, the patient is assessed by a number of specialists – orthopaedic surgeon, psychologist, rehabilitation expert, and so on – who determine the best treatment for each case. Currently, the tendency at the Pain Units involves combining pharmacological treatment, surgical techniques, psychotherapy and rehabilitation.

In the case of the University Hospital of Navarra, the Pain Unit is made up of a clinical pharmacologist, two anaesthetists, a family doctor, specialised nurses – always supported by psychiatrists, rehabilitation medics and other specialities, in traumatology. Applying surgical techniques in about 70% of the patient. Together with the accumulated experience, it is considered that this type of treatment provides better efficacy against persistent chronic pain.

Stroke Volume Variation Fails To Predict Fluid Responsiveness In Abdominal Surgery
Measuring stroke volume variation (SVV) using the FloTrac/ Vigileo system does not reliably predict fluid responsiveness in patients undergoing major abdominal surgery, researchers report.

Hypovolaemia during major abdominal surgery poses a constant threat for organ dysfunction and is associated with poor outcomes after surgery, explain Daniel Lahner, from Medical University of Vienna in Austria, and colleagues.

They investigated SVV as a possible predictor of hypovolaemia and fluid responsiveness using a device, FloTrac/ Vigileo, which determines the variation by arterial pulse contour analysis.

The researchers used the esophageal Doppler to measure fluid responsiveness in 20 patients undergoing major abdominal surgery. Fluid boluses of 250 ml each were administered in case of a decrease in corrected flow time to less than 350 ms.

The patients received 67 fluid boluses – 10 received 26 colloid boluses and 10 received 41 crystalloid boluses. Fifty-two of the 67 fluid boluses administered resulted in fluid responsiveness, defined as an increase in stroke volume index of more than 10%.

The results showed that SVV measured using FloTrac/Vigileo achieved an area under the receiver operating characteristic (ROC) curve of 0.512 in patients receiving colloid or crystalloid boluses.

Based on a cut-off point of 8.5% or above SVV predicted fluid responsiveness with a sensitivity of 77% and a specificity of 43%. The positive predictive value was 84% and the negative predictive value was 33%.

Lahner and team say that the sensitivity and specificity and the area under the ROC achieved in their study “underline the limited clinical usefulness of [the] FloTrac/Vigileo system obtained SVV threshold value as a predictor for fluid responsiveness.”

They therefore say more work is required before its clinical use can be recommended.

One failure to address is the recalibration interval, which the researchers say might be too long to accurately detect changes in SVV.

Children Can ‘Imagine Away’ Pain
Children can be taught to use their imagination to tackle frequent bouts of stomach pain, research shows.

A relaxation-type CD, asking children to imagine themselves in scenarios like floating on a cloud led to dramatic improvements in abdominal pain. The US researchers said the technique worked particularly well in children as they have such fertile imaginations.

It has been estimated that frequent stomach pain with no identifiable cause affects up to one in five children.

The research, published in the journal Pediatrics, follows on from studies showing hypnosis is an effective treatment for a range of conditions known as functional abdominal pain, which includes things like irritable bowel syndrome.

In this study, the children had 20 minute sessions of “guided imagery” - a technique which prompts the subject to imagine things which will reduce their discomfort.

One example is letting a special shiny object melt into their hand and then placing their hand on their belly, spreading warmth and light from the hand inside the tummy to make a protective barrier inside that prevents anything from irritating the belly.

The researchers, from the University of North Carolina and Duke University Medical Center, said a lack of therapists led them to the idea of using a CD to deliver the sessions.

Thirty children aged between six and 15 years took part in the study - half of whom used the CDs daily for eight weeks and the rest of whom got normal treatment. Among those who had used the CDs, 73.3% reported that their abdominal pain was reduced by half or more by the end of the treatment course compared with 26.7% in the standard care group.

In two-thirds of children the improvements were still apparent six months later.

It is not clear exactly how the technique works but studies have shown it is partly about reducing anxiety but there is also a direct effect on the pain response.

Some researchers think hypnosis-like techniques reduce “hypersensitivity” in conditions such as irritable bowel syndrome.

Study leader Dr Miranda van Tilburg said it was especially exciting that the children were able to use the technique on their own.

Such self-administered treatment is, of course, very inexpensive and can be used in addition to other treatments, which potentially opens the door for easily enhancing treatment outcomes for a lot of children suffering from frequent stomach aches.

“Children are very good at using their imagination - when you use this in adults you have to overcome a barrier first.”

Professor David Candy, a consultant paediatric gastroenterologist at Western Sussex Hospitals, said his team had tried hypnosis in a small group of children with severe abdominal pain problems and had 100% success rate.

He added they are now keen to try the guided imagery technique to see if they can replicate the US findings.

There is really a dearth of information on how to manage children with abdominal pain and it’s a very common problem which keeps children out of school.”

Endoscopic Ultrasound – Fine Needle Aspiration Feasible, Safe For Children
In the November issue of GIE: Gastrointestinal Endoscopy, a study examining endoscopic ultrasound (EUS) found that EUS and EUS-fine needle aspiration (FNA) is feasible and safe in paediatric patients, and may have a significant impact on paediatric gastrointestinal (GI), pancreatobiliary, and mediastinal diseases.

Although the role of EUS is well established in adult GI and pacreatobiliary disease, knowledge of EUS in children is limited. This is because of the relatively low incidence of pancreatobiliary and GI neoplasias, presumptive limitations in the size of EUS equipment and accessories, the need for general anaesthesia, and the lack of highly trained and experienced endosonographers in paediatric patients.

With the refinement of techniques and advances in endosonographic design, several case reports and studies found successful use of EUS in paediatric patients.

The aim of the current retrospective study was to describe clinical and demographic characteristics, indications, feasibility, safety, and impact of EUS in the paediatric patient population from two university hospitals.

All EUS procedures performed from September 2001 to September 2008 at the Oregon Health & Science University, Portland, Oregon, and the University of Utah School of Medicine, Salt Lake City, Utah were reviewed. Patients aged younger than 18 years were identified.

All EUS procedures were performed by experienced endosonographers who independently performed more than 1,000 EUS procedures in adults. All procedures were performed in facilities specialised in the care of adult patients.

Over the 7-year period, 40 of 6,724 EUS procedures were performed on 38 patients aged younger than 18 years. The procedure was successful in all patients and no complications related to sedation, EUS or EUS-FNA were encountered.

The study also found that standard adult EUS equipment and accessories could be used in all patients to successfully perform procedures in children aged three years or older.

Disorders of the pancreatobiliary system were the primary indication in the majority of the study cases (62.5%), which is in keeping with previous studies.

EUS allows the physician to avoid having to perform more invasive and higher risk procedures such as endoscopic retrograde cholangiopancreatography, laparoscopy, and mediastinoscopy.

Although standard-size instruments may be used even in younger children, the need for deeper levels of sedation and maintenance of a patent airway will frequently require the assistance of anaesthesia services.

Involving Doctors In Equipment Choices Will Improve Patient Safety
Asking an anaesthetist to use equipment on a patient when they are unfamiliar with it is as bad as asking a pilot to fly a jumbo jet full of passengers when they are only used to DC10s.

That’s the view expressed by Dr John Carter, Chair of the working party behind the latest safety guidelines produced by the Association of Anaesthetists of Great Britain and Ireland (AAGBI).

The Association has introduced the guidelines, on the Safe Management of Anaesthetic Related Equipment, amid concerns that some of its members are being asked to use equipment they are unfamiliar with and played no role in choosing.

“Sometimes doctors will have equipment foisted on them because it is the cheapest equipment available” says Dr Carter, a consultant anaesthetist from Bristol.

“One of the reasons behind these guidelines is to make sure that the people who use the equipment have a real say in what is provided. I know of cases where anaesthetists recommended particular pieces of equipment and the hospital trusts bought other makes and models just because they were cheaper.

“It’s rather like expecting an airline pilot who has been trained to fly DC10s to turn up for work one day to find he’s got to take a jumbo jet up! Nobody would want to be in that situation on that plane and patients shouldn’t be put in the position of having an anaesthetist looking after them who is unfamiliar with the equipment he or she is using.”The AAGBI, which provides its members with advice on all aspects of patient safety, points out that about 20 per cent of the critical incidents in anaesthesia are thought to be down to equipment failure. Half of these are linked to user error or inappropriate use, indicating a lack of training in the correct use of equipment.

“Anaesthetists are encouraged to report any incident that may lead to a compromise in patient safety and the level of incident reporting is fairly high in anaesthesia” says Dr Carter. “That means that we have a fairly clear picture of the safety issues that arise and can make sure the guidance we produce focuses on those areas.”

The AAGBI’s ten-point action plan makes it clear that anaesthetists should be intimately involved in specifying what anaesthetic equipment should be used and in what their hospital trust chooses to buy.

“Making sure that staff receive adequate training is also essential and there should be an effective early warning system to ensure that any concerns are raised promptly and acted on,” says Dr Carter.

“These steps are vital to ensure that anaesthetists are using high-quality, safe equipment that enables them to provide safe care to their patients.

“We appreciate that cost needs to be a factor, but it is essential that it is not the driving force behind equipment decisions. Safety, quality and performance are top priorities and providing equipment that staff feel confident and competent using is paramount.”

Vexing Questions For Anaesthetists
How can postoperative delirium and postoperative cognitive dysfunction be avoided? How is it best to address the problem of epilepsy? How can anaesthetists cope better with a patient death under anaesthesia? These difficult questions were among many addressed by specialists at HAI 2009, the annual conference of the German Society for Anaesthesiology and Intensive Care Medicine (DGAI).

Postoperatively, delirium and cognitive dysfunction are serious problems. How can these events be avoided? The question is clearly significant, but why? Conference president Professor Claudia Spies MD spoke about this. She is a member of the executive committee of the Association of Scientific Medical Societies in Germany (AWMF) and managing director of Charité Centre of Anaesthesiology and Intensive Care Medicine, where she is in charge of several research groups examining postoperative delirium and postoperative cognitive dysfunction.

“In anaesthesiology and intensive care medicine both medical conditions are widely underestimated,” Professor Spies explained. “Studies have proved that postoperative delirium is associated with a high morbidity rate, and mortality within six months is three times higher. In addition, the complication rate is considerably higher and aftercare more complex. We still know very little about postoperative cognitive dysfunction. We recognised only recently, in 2006/2007, that it has a relatively high incidence. The extent of the problem becomes obvious when considering that patients cannot concentrate any more, are unable to work, or cannot live anymore in their former circumstances, for example, after intervention 30% of over 80-year-olds cannot. Therefore we think better strategies to indicate, treat and particularly prevent postoperative delirium and cognitive dysfunction, are absolutely essential.

“In anaesthetic recovery rooms 15-50% of patients are affected by postoperative delirium, but only about 2-3% of German hospitals screen for delirium in the recovery room. In the intensive care unit (ICU) the situation is more dramatic: about 30-80% of patients needing artificial respiration suffer delirium, but in two thirds of cases it goes unrecognised.

“Preliminary findings indicate that 30% of patients aged 18-59 years old have a cognitive disorder at hospital discharge and at least 5% of discharged patients have it after three months. Older patients are more affected: 40% after hospital discharge and 12% after three months.”

Professor Spies pointed out that there are potential causes of postoperative delirium. “In many cases a delirium indicates an incipient infection. However, other reasons, or an accumulation of different reasons, can cause it, such as a lack of special drugs, or alcohol in addicted patients, too much or little intra- and postoperative fluid volume, a lack of intra- or postoperative pain therapy, and so forth. To know more about the causes for postoperative cognitive dysfunction we still need more research. Certainly postoperative delirium can entail a long-term cognitive dysfunction.”

How are these problems best treated? “The most important is to detect a delirium as soon as possible. Then a different diagnosis and an adequate treatment should take place. An incipient infection, for example, should be treated with antibiotics. In addition, drugs should be given that counteract the symptoms of delirium to decrease the stress. In the case of postoperative cognitive dysfunction it is generally too late to medicate.

How can such cases be prevented? Professor Spies believes that, due to the high incidence and low detection rate of postoperative delirium, world- and nationwide routine screenings are needed and that these should be “… in line with actual guidelines, for example the Nurses Delirium Screening Scale (Nu-DESC), which is a measuring instrument for the clinical diagnostics of delirium. It is quickly operable, care-based and thus can be easily integrated into everyday routine. Besides we should concentrate in prevention. We found out, that the duration of sobriety prior to surgery and the choice of intra-operative opioid reduce the incidents of postoperative delirium. In terms of postoperative cognitive dysfunction, we need more research.”

Epilepsy - Until now the problem of an epileptic fit occurring during anaesthesia has also received little attention. Anaesthetist Dr Ingrid Rundshagen, Associate Professor at the Charité University of Medicine Berlin, pointed out that there is still a lack of research on the proconvulsive effect of anaesthetics. Worldwide the incidence of epileptic fits ranges between 0.3 to 0.5% and 5-10% of people suffer a convulsion in their lifetime. To reduce the risk of convulsions during surgery Professor Rundshagen said it is absolutely necessary to know exactly which anaesthetic could provoke them, requiring an evidence-based, randomised survey with EEG monitoring.

Deaths during anaesthesia - What happens if a patient dies during anaesthesia? Addressing a packed auditorium, Professor Hinnerk Wulf (Philipps University Hospital, Marburg) revealed that, unlike emergency, intensive care and palliative care specialists, in the case of a death during treatment anaesthetists still have no adequate support. In addition this issue is widely disregarded in academic studies and post graduate courses. The professor quoted one study which revealed that 92% of anaesthetists experienced the death of a patient during anaesthesia and 11% reported that this had a long-term impact of their work. In fact, the follow-up care for anaesthetists depends only upon the personal initiatives of colleagues or a superior.

Prof. Wulf interestingly proposed learning from German railways. In a lecture given by psychologist Viola Margraf, of the German Railways (DB) health service division, she explained that every train driver is statistically confronted twice in his/her career with a suicide – and two to three humans commit suicide every day on DB rails.

Thus, 15 years ago, the DB health service developed a treatment concept for distressed train drivers. This addresses three areas: prevention, intervention and after-care. Prevention provides every train driver with special stress and conflict management for two days. Intervention provides concrete instruction as to how to act if faced with a suicide; the train driver immediately comes under the care of a supervisor. Aftercare offers a voluntary counselling interview with a psychologist.

Quoting an internal study, she said that working days lost due to a reaction to a suicide could be reduced from 22.9% to 13.8% due to this model.

The intense interest among participating anaesthetists and the numerous contributions demonstrated a clear need to address the important issue of patient deaths during anaesthesia.

European Hospitals Test Anaesthetists’ Skills On Computers, Not People, Using SensAble’s Haptic Devices
Pan-European clinical trials led by Cork University Hospital assesses whether lumbar puncture skills can be accurately assessed on computers, at zero risk to patients

SensAble Technologies, Inc., announced that its customer, the Cork University Hospital, is leading clinical trials in two European hospitals using a haptically-enabled computer simulation system for testing physician competency in administering spinal anaesthesia. SensAble is a manufacturer of haptic devices and toolkits, and its PHANTOM® force-feedback haptic devices and programming technologies were used to develop this simulator. The clinical trials at Cork University Hospital in Ireland and the University of Pecs in Hungary explore whether virtual reality simulations can accurately assess high-risk clinical skills without the need for physicians to practice on patients.

With spinal procedures potentially causing irreversible injury to patients, and an adverse affect rate of up to 30 percent - from spinal headaches to cardiac arrest, neurological impact and even death1 - they present a compelling case for the role of computer-based simulators to train physicians on procedures that require a delicate sense of touch. The trials are the culmination of a two-year project, Medical Competency Assessment Procedure (MedCAP), financially supported by the European Commission through the Lifelong Learning Programme, Leonardo da Vinci sub programme. If successful, MedCAP’s creators envision future teaching and testing applications in other specialties.

“Placing a fine needle very close to the spinal cord requires the operator to feel very small changes in resistance as the needle tip passes through each anatomical structure. Traditionally this has been learned by practising on patients under supervision. Clearly that is not ideal. Furthermore, in today’s clinical setting, medical trainees have fewer opportunities to practice,” said Prof. George Shorten, director of the anaesthesia department at Cork University Hospital. “We can’t assume that practitioners can perform high-risk procedures just because they have been licensed for a certain number of years, or because they answered questions correctly on an exam. Touch-enabled computer simulators allow a variety of clinical cases to be presented, and provide objective and quantifiable metrics which together describe physician competence. These learning opportunities pose zero risk to patients while physicians demonstrate competency.”

Led by the Cork University Hospital, the MedCAP team developed a virtual reality computer-based simulator with which anesthetists hold a SensAble haptic device – like a high-precision Nintendo Wii – as 3D computer screens direct them to perform a lumbar puncture procedure. The haptic device literally pushes back on the user’s hand so they feel surface tension as the spinal needle meets the skin; a “pop” as it punctures the skin; and the different viscosities of tissue, ligaments, cerebrospinal fluid and dura mater, the tough outer layer of the meninges surrounding the spinal cord. Should trainees puncture too far and enter the other meninges or the spinal cord itself - or puncture only into the skin - they feel different sensations and receive immediate alarms and on-screen error messages.

In the clinical trials, groups of skilled anaesthetists and residents-in-training must perform a lumbar puncture on six virtual patients who present at different ages and complications, and answer a battery of clinical care questions. The simulator is blind to the user’s experience level, merely recording and scoring them on nearly 200 competencies and calculating a score that suggests the user is either a knowledgeable practitioner, or a trainee. Users receive detailed feedback on their performance, so that they can practise any areas of weakness until they achieve competency. Once clinical trials are completed this fall, results are expected to show that the practicing anaesthetists score better than residents-in-training - suggesting the simulator is a valid competency assessment tool.

“It’s not enough to train specialists with the traditional ‘do one, see one, teach one’ approach to learning by apprenticeship on patients,” said Erik Lovquist, researcher at the University of Limerick’s Interactive Design Center, who was technical lead of the collaboratively developed haptically enabled simulator. “The MedCAP-system offers the potential to assess competence of those performing other high stakes medical procedures in a valid and reliable way”.

The MedCAP partnership includes the Interaction Design Centre, University of Limerick, Ireland and the University Graz, Austria as well as the clinical centers in Cork and Pecs. Its approach is based on the competence-based knowledge space theory, developed by Dietrich Albert and the team at the University of Graz.

“With today’s haptic devices and toolkits it’s possible to create computer-based systems that mimic and quantify even the most subconscious aspects of human touch,” said Dr. David Chen, chief technology officer of SensAble Technologies. “The MedCAP project showcases the invaluable role that haptically-enabled simulators can play in medical certification, beyond its already – demonstrated role in training – and the sophistication that SensAble’s haptics technology allows.”
