Dummy patient helps train medics in Berkshire

A new operating theatre, set up to train medical staff in Berkshire, features one of the most advanced dummy patients so trainees can carry out mock operations. The pupils react to light, and it has breath and heart sounds, allowing any type of emergency to be simulated. The idea is to recreate emergencues that medics don't usually see. 

BBC South's health correspondent David Fenton had a go on the dummy, who has been named Davina. Watch the BBC report at http://tinyurl.com/yzxlxra

New strategies may cut screening errors

A study in Current Biology has found a possible way to cut the number of mistakes made by medical staff looking for breast and cervical cancers. US researchers found that the time spent and errors made made during a visual search for target items in X-ray images varied according to the chances of finding the target.

"If you are trying to find 20 cases of breast cancer from 40 mammograms, you'll find more of them than if you look for the same 20 cases from 2,000 mammograms", said lead author, Jeremy Wolfe of Harvard Medical School. 

The authors say that doing a booster exercise before starting work helps them to visualise what they are looking for and improves their search success rate in the subsequent session. 

Richard Evans, Chief Executive of the Society of Radiographers said: "I look forward to seeing more details about this research, but radiographers would welcome techniques which help ensure the best possible standards." He pointed out that the NHS already monitors the performance of everyone involved in breast screening through a regular audit. Source: BBC, 16 January, 2010. tinyurl.com/yg4mson

NHS faces 'potentially serious problems' from wrong prescriptions

The Telegraph reports on the problems faced by junior doctors, who fill out five or six prescription forms on average during their  time in medical school only to have to complete dozens on their first day on the wards. The inadequate preparation contributes to errors that could harm patients - such as omitting drugs, wrong doses, not taking account of a patient's allergies, illegible handwriting or ambiguous orders. According to the General Medical Council 10 per cent of all prescriptions issued by doctors contained such errors. 

Now the British Pharmacological Society (BPS) is calling for an exam for medical students and a "prescribing simulator" complete with virtual patients to be introduced to the curriculum so that medics are better prepared when they start in hospitals. Professor Simon Maxwell, chairman of the BPS, said: "We would not accept this kind of error rate in other industries such as aviation. It is a recipe for problems."

Nearly one in 10 prescriptions has mistakes


Nearly one in 10 hospital prescriptions contains a mistake, ranging from the minor to the potentially lethal, according to research commissioned by the General Medical Council. However, very few errors would have caused serious harm. The research team, led by Professor Tim Dornan of the University of Manchester, examined the issue amid rising fears inexperienced doctors were making prescription errors which could, at worst, result in a patient dying. 

The team examined 124,260 prescriptions across 19 hospitals - and found just under 9% contained errors. Of these 11,077 errors, overwhelmingly intercepted and corrected before reaching the patient, about 2% contained potentially lethal instructions - such as failing to take account of a patient's allergies. More than half involved errors in which a patient's medication was not prescribed and 40% were involved illegible or ambiguous prescriptions.

Very few of these mistakes caused actual harm to a patient because on the whole they were stopped by senior doctors, nurses - and in particular pharmacists. But the study did not find doctors fresh out of medical school were making the most mistakes - as has often been suggested,

"The research shows the complexity of the circumstances in which errors occur and argues against education as a single quick-fix solution”, said Professor Dornan. However, the GMC is calling for a UK-wide standard prescription chart as exists in Wales. Support for the idea is provided by Professor Peter Rubin (chairman of the GMC), Dr Hamish Meldrum (British Medical Association), and Joyce Robins (Co-Director of Patient Concern). A Department of Health spokesman said it would continue to look into the benefits of electronic prescribing system. 

However, Professor Simon Maxwell, of the British Pharmacological Society said he was “dismayed at the suggestion that improved education and training is not a central part of the solution. There is plenty of evidence from around the world to show that when appropriate education and training are delivered, prescribing improves." Source: BBC, 3 December 2009. http://tinyurl.com/ydfbepb

Intensive care errors ‘frequent’

Errors in the administration of injected medication occur frequently in intensive care units, a study of 113 units across 27 countries suggests. Over a 24-hour period, 441 patients out of 1,300 were subject to errors, and seven suffered permanent harm. Nearly half of the affected patients suffered more than one mistake. The most frequent errors related to the wrong time of administration and missing doses. Stress, tiredness, recent changes in the drug’s name, poor communication, and protocol violations were cited as contributing factors. Lead researcher Dr Andreas Valentin recommended error reporting systems and routine checks at shift changes. The Intensive Care Society said many units had developed patient safety training programmes, including measures to learn from ‘near misses’. Work was also under way to standardise concentrations of some drugs for critically ill patients, refine the use of antibiotics and minimise the risk of adverse drug reactions.
