Artificial intelligence better than doctors at diagnosing treating patients

AI can think like a doctor, but faster and with more information, Indiana U. researchers find

Applying the same technologies used for voice recognition and credit-card fraud detection to medical treatments could cut costs and improve patient outcomes by almost 50%, according to new research.

The research by Indiana University found that using patient data with machine-learning algorithms can drastically improve both the cost and quality of health care through simulation modeling.

The computer models simulated numerous alternative treatment paths out into the future and continually planned and re-planned treatment as new information became available. In other words, it can "think like a doctor," according to the university.

This is not the first time artificial intelligence has been brought to bear on healthcare.

Last year, IBM announced that its Watson supercomputer would be used in evaluating evidence-based cancer treatment options for physicians, driving the decision-making process down to a matter of seconds. The Watson supercomputer was first offered to Cedars-Sinai's Samuel Oschin Comprehensive Cancer Institute in Los Angeles. Later that year, Watson was brought in to help Memorial Sloan-Kettering Cancer Center physicians diagnose and treat cancer patients.

The new research at Indiana University was non-disease-specific -- it could work for any diagnosis or disorder, simply by plugging in the relevant information. The research is aimed at addressing three issues related to health care in the U.S.: Rising costs expected to reach 30% of the gross domestic product by 2050; quality of care where patients receive the correct diagnosis and treatment less than half the time on a first visit; and a lag time of 13 to 17 years between research and practice in clinical care, the university said.

The research was performed by computer science assistant professor Kris Hauser and doctoral student Casey C. Bennett. The researchers used 500 randomly selected patients for the computer simulations.

The two researchers had access to clinical data, demographics and other information from 6,700 patients kept by the Centerstone Research Institute, a nonprofit provider of community-based behavioral health care. From 60% to 70% of the patients had major clinical depression diagnoses but also had chronic physical disorders including diabetes, hypertension and cardiovascular disease, which were used in the simulations.

Using real patient data, the researchers compared actual doctor performance and patient outcomes against computer decision-making models.
