How is AI transforming the Healthcare industry?

Here are eight ways in which AI technology and solutions are helping drive the transformation of the healthcare industry:

1. It is expanding the field of medical research

The average time for a drug to travel from the lab to the market is 12 years in the United States. What’s even more astounding is that only five out of 5,000 drugs make it to the human testing phase, and just one in those five is approved for human consumption.

The lengthy research process comes with exorbitant costs. On average, it costs around US$ 359 million to develop a new drug and launch it in the market.

This is where AI is helping to speed up things. As mentioned earlier, AI solutions help streamline the drug research and discovery process, allowing pharma companies to launch their products faster than before. As the drug discovery time (from lab to patient) reduces, the manufacturing costs also drop significantly. Consequently, pharma companies can launch affordable drugs on the market.

2. It Aids Early Detection

AI technology plays a pivotal role in the early and accurate detection of various diseases, particularly cancer, during the early stages itself. The American Cancer Society maintains that a high percentage of mammograms deliver false results, which leads to 1 in 2 healthy women being wrongly diagnosed with breast cancer.

However, AI is helping combat this issue by reviewing and analyzing mammograms 30 times faster than traditional methods with 99% accuracy. Moreover, the increasing popularity of remotely controlled wearables and medical devices also help doctors supervise early-stage heart diseases, enabling them to cure the problems during the treatable stages
