Using simulators to train surgeons makes them quicker and better, a study shows.

Computer simulators are used in the NHS, but they are not widespread

The Danish research comes after calls to introduce strict guidelines for NHS doctors.

Unlike many other countries the use of simulators is not a formal part of the training process.

But the Copenhagen University Hospital team said it should be after monitoring the performance of 24 junior doctors carrying out keyhole surgery（锁眼切口手术）.

The researchers put the obstetrics（助产术） and gynaecology（妇科医学） medics in two groups - one which had the traditional training of working alongside doctors and tutoring and another which supplemented this with seven hours simulator training.

They found that those that used the computer simulators were twice as quick, taking just 12 minutes to complete the operation on a patient.

They also carried out better procedures, according to a points system used to judge the quality of the work.

Lead researcher Christian¹ Rifbjerg Larsen said: "Simulator training should be incorporated into the curriculum for all surgical² trainees⁴ before they embark⁵ on patient procedures.

"This can potentially improve patient safety and improve operation room efficiency."

The publication of the study in the British Medical Journal comes after Sir Liam Donaldson, England's chief medical officer, called for more simulation training in the NHS.

In his annual report in March, he said simulators "reduce errors and make surgery much safer".

Guidelines

Simulators are already used in the NHS for everything from practising surgery to administering drugs.

But unlike other countries, such as Israel, there are no strict guidelines about how much time doctors should spend on them.

The British Medical Association is also keen on increased use of simulators, although it has said real-life training with consultants⁶ should not be compromised.

Roger Kneebone, an expert in surgical education at Imperial College London, agreed.

He said: "Simulation offers obvious benefits. Sophisticated virtual reality simulators can provide anatomically realistic recreations of many operations."

But he added trainee³（练习生，新兵） surgeons also needed to develop communication and leadership skills as well as be ready for the unexpected - all of which required different training to simulators.

Health Minister Lord Darzi said high quality training is essential.

"In my own career as a surgeon I have seen the huge benefits which innovations in surgical simulation have made possible so I am pleased but not surprised by these findings which we welcome.

"We are working with NHS colleagues to develop a new strategy for simulation-based training in order to ensure the best training for doctors and the best quality of care for our patients."
