as someone who finished their epq last year, it is not a bad title as artificial intelligence has a lot of research online. however i would say specify what you mean by 'issues' and 'improve' the NHS.
whilst i assume you have only just started your epq project and can still leave it relatively broad, you definitely want to narrow it down to possibly focus on one certain issue or section of the NHS. you will find that when it comes to actually writing it, it will be hard to go into detail into multiple areas without going over your word count.
hope this helps
