Is it wise to get real on a startup idea when you have no background on the subject....
There are tons of "ideas" in this space. It has slow adoption because of high barriers by the end user. You will need a ton of cash even if your platform is unique. You need to vet yours before you go further. Having a partner who does understand this space will be crucial to your plan.
The main challenges in healthcare sector is the unbelievable amount of bureaucracy you will face and the fragmented nature of digitalization in healthcare. You would have to integrate data coming from an immense variety of sources, and they will be locked behind language and access barriers. Think global, that's what we are doing here anyway, but act local, e.g. start with the hospitals in your city. You will definitely need people to open doors for you, too, you will find it to be more conservative as well.
The simple answer is no. As @Dane says, this particular industry has a high barrier to entry for many reasons. It also has a lot of problems that still need to be solved. You don't need a medical background, but you do need to keenly understand how the medical records business operates. You can learn this, either through extensive research, or you can temporarily go work for a company in the industry you wish to serve.
Consider that you might be able to find a company interested in adopting your ideas (once you have turned them into a plan) and that you could advance inside a company like that, managing the service as a new product for the company. But for credibility sake, you will need some experience in the industry before a company is going to take your idea very seriously.
Starting independently in medical records management, as already said, is likely going to require a lot of money. So if you have a lot of money, great. You can hire some people with more direct experience to help you with some of that money.
People who have a passion project typically take the time to get involved in the industry to learn. When I wanted to build hotels, I went to work for a hotel company for a year, I also worked for a hotelier trade association, and in that process, I learned that I really didn't want to build hotels. But what I did find was a different opportunity, and a method of pursuing it.
