Yes, we can use blockchain technology for healthcare. It has diverse applications, and healthcare is also one of them. Particularly in Heathcare we can use it for securing patients records on blockchain which provides immutable and tamper proof record storage. Moreover, we can use blockchain for exchanging data among hospitals, diagnostic laboratories, pharmacy firms, and physicians using a single platform which eliminates data security issues and also enhance collaboration ensuring fast and secure data transfer which is critical in healthcare. I hope this helps.
