The modest stethoscope has joined the Artificial Intelligence revolution, tapping into the power of machine learning to help health-care providers screen for diseases of the heart and lung.
Since its adoption more than 200 years ago, the stethoscope has served as both a routine exam tool and a visible reminder of the doctor’s training. It is recognizable worldwide and, for most clinicians, has remained an analogue instrument. The first electronic stethoscopes were created more than 20 years ago and feature enhancements to amplify sound and allow for digital recording.
The risks include limitations in performance if AI models are not properly trained. The accuracy of the AI algorithm depends on the collection of sufficient data that is representative of the population at large. “This technology has to be validated across a variety of murmurs in a variety of clinical environments and situations,” says Andrew Choi, Professor of Medicine and Radiology at George Washington University. “Many of our patients are not the ideal patients,” he adds, noting that initial validation typically involves patients with clear heart sounds.
The subconscious transfer of decision-making to an automated system is called automation bias, one of many cognitive biases the health-care provider must confront. There are many reasons providers mayand uncritically accept the heuristics of AI, including inexperience, complex workloads and time constraints, according to a systematic review of the phenomenon.
“I want to stay connected to the patient. I take pride in my patient examinations,” he says. “I think that’s one of the important things we provide to patients in the primary care setting, and I’m not looking to sever that part of the relationship.”The former owners of a home on Vancouver's west side have continued living in it despite selling it for nearly $4 million last June.
