I don’t see this as an unusual situation at all. Nothing that you have described in your London visit would be likely to cause you difficulty in reentering the United Kingdom.
Britain and Ireland do not really “share a common immigration system” but the two countries do take part in the Common Travel Area, which I am sure is what you were referring to. Under the agreements of the CTA, each immigration authority honours the decisions of the other, and most everybody can travel freely across the borders.
If you would like to share more information about why you feel you may be denied entry, feel free to elaborate.
After a rule change in 2017 NHS would have asked you to pay up front for chargeable medical services. Note that emergency services in Accident & Emergency are not chargeable and you would not be billed for such services. Even more so that you apparently left A&E before receiving any service at all. So this should not affect your trip in any way.
As for having been reported as a missing person, if you’re still officially missing then it might show up, but as you aren’t actually missing it ought to be something that is easily cleared up. I would not expect this to be a significant event even if it happened.
