Pneumonia, an infection in the lungs that causes difficulty breathing, is most commonly diagnosed through chest X-rays.

Typically, those chest X-rays are read by radiologists, but mean that in the future, it could be harder to get a diagnosis promptly.

Early and accurate diagnosis of pneumonia is important as it accounts for about 15% of deaths in children younger than 5 years old, according to the .

That鈥檚 where machine learning comes in, said Sridhar Tayur, Ford Distinguished Research Chair and University Professor of Operations Management in 麻豆村鈥檚 Tepper School of Business.

鈥淢achine learning is used for prediction, and in health care we want to predict if somebody has a disease or not,鈥� he said. 鈥淚f you give enough examples of images that have pneumonia and not pneumonia, because there are two cases, this is called binary classification.鈥�

Tayur and a team of researchers studied a technique called support vector machine for classification using quantum-inspired computing, then compared it to other methods in a recent titled 鈥淧neumonia detection by binary classification: classical, quantum, and hybrid approaches for support vector machine.鈥�

鈥淲e showed that it is pretty competitive,鈥� he said. 鈥淚t makes fewer mistakes, and it takes less time.鈥�

A summary of this research was also in the same issue that describes another application in health care in the area of Cancer Genomics.

How can quantum computing be applied to health care?

Tayur founded the Quantum Technologies Group at Carnegie Mellon to better understand and apply quantum computing methods to industries such as health care.

鈥淧eople are always looking for more efficient ways of solving problems and novel methods and technologies to tackle it,鈥� he said.

In the mid-20th century, scientists who led the first quantum revolution changed the world with advances such as the transistor, laser and atomic clock. While hardware to compute using qubits 鈥� which are the building blocks of quantum computing 鈥� is still in development, simulators can tackle problems of realistic size with specially tailored algorithms, which is why this approach is known as quantum-inspired computing.

鈥淎ssuming that qubit devices of larger size and lower errors are going to be developed, we can simulate them on a regular computer right now,鈥� Tayur said.

What are the challenges facing health care in adopting AI?

These technologies, however, are still at the leading edge of considerations when it comes to the application of artificial intelligence in health care.

To do so, the industry has four challenges ahead of it, as Tayur with Tinglong Dai of Johns Hopkins Carey Business School: physician buy-in, patient acceptance, provider investment and payer support.

To achieve these goals, any AI applied to health care systems should consider how physicians will integrate it into their practices, and then review how patients perceive the role of AI in health care delivery.

鈥淲e wrote that paper in 2022, but things haven鈥檛 changed that much. It鈥檚 not just about building a better mousetrap, it鈥檚 about getting people to use that mousetrap,鈥� he said, referencing that success comes from simply designing the best product.

Tayur explained that have been approved by the FDA, but wide adoption of these technologies is still just beginning, in part because of the state of the health care industry and where financial incentives lie.

鈥淗aving a good product is necessary, but it鈥檚 not sufficient,鈥� he said. 鈥淵ou still need to figure out how people are going to use it, and who is going to pay for it.鈥�

Another major consideration is liability. When it comes to devices, a company might encourage doctors to adopt them, but what happens if the device gives a faulty diagnosis or a doctor gives an incorrect interpretation of the data from the device? What happens if the physician disagrees with the AI recommendation?

鈥淚n the paper, we talk about the fact that you have to figure out the business case, both risk and reward, along with training and upfront investments in adopting the technology,鈥� he said.

In applying elements of AI and quantum computing to health care, Tayur said while at least some progress has been made, there is still a long way to go.

鈥淢any times, what happens is a lot of the AI in health care is derived by scientists and research physicians,鈥� he said. 鈥淲hat they need is a business person who is less enamored by the mousetrap and more sensitive to the patient journey and commercial viability.鈥�
