Such cockpit rules, and other strategies lend themselves well to healthcare. During the critical phases of a flight, pilots must refrain from all non-essential conversation to avoid unnecessary distractions. Minimising distractions is also particularly important. Those who are revealed to be challenged in making right-left decisions, would at least have this deficiency flagged up and could apply extra vigilance in certain situations. We need to develop strategies to reduce such error-provoking situations and to raise student and teacher awareness of the fact that some individuals are more prone to right-left confusion.Īs the people at risk often don’t think they have a problem, testing of the ability to discriminate against right-left discrimination – for example through online psychometric tests – could be offered to students to measure their ability. In healthcare, training – starting at an undergraduate level – needs to make students mindful of the challenges of making right-left decisions and the impact that distractions can have on such critical decisions. It appears however that these techniques remain fallible and fail to combat this issue in all cases. Those who have difficulty in telling right from left often develop their own techniques – for example placing their left thumb at right angles to their index finger to make an “L” representation for their “left” side. So many students thought they were good at distinguishing right from left when, objectively measured, they weren’t. The “distraction effect” was greater for older and female students.Īn individual’s ability to self-determine how well they could distinguish right from left was also often imprecise.

Asking them a series of questions while they were trying to distinguish right from left had an even greater impact. Even the background noise of a ward environment was enough to throw some medical students off when making right-left judgements. While objectively measuring 234 medical students' ability to distinguish right from left, we subjected them to the typical ambient noise of a ward environment and interrupted them with clinical questions. In research we published in Medical Education, we explored the impact of such interruptions on medical students’ ability to correctly discriminate right from left. Doctors are often subject to distractions while working receiving telephone calls, cardiac monitors bleeping, taking questions from colleagues, patients and their relatives – the clinical environment can be very challenging. Hospitals and other health settings are busy and complex places to work in. The literature would appear to suggest that men demonstrate a greater degree of visuo-spatial function.ĭistinguishing right from left also never occurs in isolation. Evidence would suggest that right-left confusion is more common in women.
While there are systems, checks and balances in place to anticipate and minimise these kinds of mistakes, when they do occur, human error is often at the root of the cause.Įrror is an inherent characteristic of human behaviour – sometimes we just get things wrong – but left-right ones may be more than a one-off accident. Some of the most tragic errors in medicine have been when surgery was performed on the wrong side of a patient: removing the wrong kidney or amputating the wrong leg. It’s hardly the end of the world if you take the wrong direction on a journey, but there are many situations where confusing right from left can have devastating consequences. So correctly distinguishing right from left in a patient also involves the visuo-spatial function of mentally rotating images. One further problem facing the health profession is that when a doctor or nurse faces a patient, their right-side is on the patient’s left-side.
You can take a test here to see how well you do. For some it is second nature but for others a considerable challenge. Left-right discrimination is a complex neuro-psychological process involving several higher neurological functions such as the ability to integrate sensory and visual information, language function and memory. If so, you’re not on your own – a significant proportion of our population has difficulty in telling right from left. Do you ever have trouble telling right from left? For example you’re taking a driving lesson and the instructor asks you to take a left turn and you pause, struggling to think of which way is left.
