AI systems can give you a better treatment than your doctor


Scientists have come up with an artificial intelligence cure to treat patients with sepsis. The system has been developed from the Imperial College London.

The researchers developed the system have analysed them on more than one lakh patients in intensive care unit have been found effective.

According to a journal published in Nature Medicine, AI system is the most reliable treatment decisions than human doctors.

AI Clinician

The system developed to strategies the best treatments and prevent sepsis is called the AI Clinician.

This system could be used by the doctors to seek help on deciding the best treatment strategy for patients.

Effects of sepsis

Sepsis can drop blood pressure drastically, which can cause a decrease in blood pressure in the blood flow of organs and oxygen and can result in multiple organ failures.

Usually, doctors used to give extra fluid mostly the salt solution in order to keep the heart pumping and raise blood pressure.

Researchers have been testing this system for over 15 years to explore whether the recommendations of the AI system are actually effective and have helped to improve the health of the patient.

The researchers have also created an AI system that would help the doctors and assess them to decide the best treatment approaches.

Reinforcement Learning

Over 90 thousand patients were analysed in intensive care units with the system using the process called reinforcement learning.

In reinforcement learning, robots learn how to make decisions to get the best possible solution to the problem.

The AI Clinician followed each patient’s case and worked out the best strategy in improving the condition of the patient.

The result has revealed that about 98 per cent of the time the solutions and approaches suggested by the AI systems where more efficient and prominent than of the strategies suggested by the human doctors.

The researchers have also resulted that the rate of mortality was lowest in patients and the decision of giving doses of fluid and vasopressor matched the I system’s suggestions with the human doctors.
