The amount paid to hospitals per patient keeps falling as the Government needs to stretch a static (real terms) budget to meet ever-growing demand. It's partly due to the post-war baby boomers getting to the age where health fails, but also more and better treatments (particularly cancer) which often require ongoing treatment and the new drugs are typically the most expensive. So hospitals aren't being run worse than when they were in surplus, there's just a drop in income which puts them into deficit.
I would predict more funding needed just to keep the status quo until the end of the year, much more on top before there's enough to fix the capacity and demand issues including social care facilities.
