There's no straightforward way to separate the specialization from the hospital name, but with some assumptions, you could perhaps use perl
to do this:
perl -pe 's/^(\S+\s+\S+\s+\S+).+experience\s([^\t]+?)\s+(\b[A-Z0-9]{2}[^\t]+?|(?:(?!\b[A-Z0-9]{2})[^\t])*)\s+\t\s+([^,]+,).+?(INR.+?PM)\s+.*/\1,\2,\3,\4\5/' file

And since it's perl based regex, you can use regex101 to get a glimpse of how it works through the regex debugger. The regex is quite straightforward, but the fact that there are many parts can make it appear daunting.
Warning: The above is able to separate the specialization based on two things:
- It tries to find the first occurrence of space followed by two uppercase characters or digits and starts matching as the hospital name when it finds it; or
- If there are no consecutive uppercase characters or digits, it takes only the first word as the specialization and the rest as the hospital name.
I know it might not solve the complete problems as there are always lines that won't fit the above rules, but that can get you started on cleaning these up. If there is anything incorrectly separated (i.e. when the specialization consists of more than 1 word and the hospital name doesn't have two consecutive upper/digit) you will have one word of the specialization correctly placed, and the rest in the hospital name.
