There's also the perverse incentives in the american medico-legal system: surgeons get sued for not performing surgery, or performing surgery badly, but they rarely get sued for performing 'unnecessary' surgery unless its com

The problem with that anecdote is that its all with the benefit of hindsight. Certainly, in this instance, non-operative management was appropriate. But the more important question is what on average happens to the entire 'population&#

Look at the graph in figure 2 - the massive overlap in the interquartlie ranges suggests that any differene in the median values can be attributed to random variation within the samples, rather than a true difference in the populations. Als

There's a role for a human-machine hybrid, and indeed there are also quite complicated control systems in work in anaesthesia. As an example, syringe pumps which perform pharmacokinetic calculations: you enter the patient's height

A common comparison is drawn to flying a plane - its a proceduralised and mechanical process for a lot of the time, but occasionally unexpected things happen and you need knowledge and skills to react quickly and prevent serious injury and

ICU ventilators are surprisingly complicated machines, we've just brought some HAMILTON-C6 machines at work if you want an idea of the top of the line. Ventilating sick COVID patients, or indeed anyone with ARDS, is one of the most cha

Doesn't seem to be very helpful - In a multicenter cohort of 302 patients with MERS coronavirus, 92% of patients treated with BiPAP failed this modality and required intubation (Alraddadi 2019)

I'm an anaesthetics and intensive care trainee, so I know something about ventilation. The reason COVID-19 patients need to get ventilated is due to a failure of oxygenation - the infection causes direct lung injury (ARDS) which impair

That wouldn't be able to detect a heart attack, its to look for atrial fibrillation (AF), which is a long-term abnormality of heart rhythm associated with increased stroke risk

To properly rule out a heart attack you would need a) A twelve-lead EKG - which requires twelve wires to be connected to specific locations on your body and b) Blood tests Therefore for a consumer-grade device to properly rule out a heart a

A pulse oximiter measures the oxygen content of arterial blood in the peripheries. A heart attack is caused by a localised blockage of the arteries to the heart, causing reduced oxygen and nutrient delivery to an area of heart muscle. A hea

That robot performs sedation, not general anaesthesia. Sedation provides a slight depression in awareness and pain sensation, and is much easier than full general anaesthesia, in which the patient is completely paralysed, unconscious, and i

I saw an asthmatic woman in A+E today, all her blood tests were in the 'normal' range, does that mean she's well? No, she was very unwell. However the test results would either be normal in someone regardless of the severity

There are certainly handoff errors, but the vast majority of these can be avoided with a well structured handoff with safety-checks built in. The problems that make handoff bad include: 1) Handoff being done at the end of a long shift, so t

Medical histories are useful when thinking about diagnosis and management. The problem is that they're rarely accessible in a concise or summarized format. Medical systems produce huge amounts of paperwork, even a simple day trip to an
