The Business Insider article you link to is saying exactly the same things as the articles I cite about what happened in the USA in 2018: makeshift wards, extraordinary measures, more and more patients needing ventilation. That's what it looks like when a lot of patients turn up sick with pneumonia at once.
Videos are dramatic but not enough to understand what's going on by themselves. You realise that, I hope?
As of Wednesday afternoon this week, Italian hospitals were not yet at the point of turning people away:

Medical facilities in Lombardy will “soon” be unable to help new coronavirus cases, regional Gov. Attilio Fontana said Wednesday, as he urged everyone to stay at home.
That was based on a quick search of English-language material. Perhaps there's a more recent update from the last 48 hours where things have changed - I'd love more recent info. But at the moment I'm seeing a lot of people who clearly believe hospitals are turning people away en-masse already, and yet I keep finding news stories where it's being officially denied by the relevant health authorities. Are they all oblivious, living in a fairy tale too? If so, isn't that a shocking scandal that needs to be talked about right now?
