In England there is apparently some debate about whether to give "self-harmers" clean blades to use or not.
Self-harmers, or "cutters" are those psychiatric disordered people who like to cut or scrape on themselves (usually on their arms) in order to feel self-inflicted pain.
When I worked in psych I had the horrific pleasure of taking care of a few dozen cutters over time. The response from the treatment team varied quite a bit - there was everything from "let's strap them down so they can't do it!" to "oh, leave them alone and let them slice away."
Ok, the latter response wasn't quite so cavalier, but there were many who realized that the cutters were going to do it one way or another. You can't follow someone around 24/7; at some point you have to let them be responsible for their actions.
From the hospital's standpoint though, there is the legal threat. How can you let someone cut on themselves under your care? Cutters very, very rarely do harm to themselves other than superficial lacerations with a little bleeding and some scars later on. But what about that one idiot who accidentaly knicks an artery and bleeds to death in their bathroom? And from the UK nurses' standpoint above, what about that idiot who cuts on themselves with a piece of dirty broken glass and gets some serious infection?
But can a hospital seriously give a patient a clean blade to slice themselves without any legal ramifications?
Even by not saying the obvious and just giving patients a "bathroom kit" containing toothbrush, toothpaste, comb, and straight razor, with the unsaid knowledge that the cutter can use the clean straight razor for their arm carvings, a hospital can still face a good legal thrashing.
The argument that giving out blades is encouraging cutting behavior is silly, just as much as giving out condoms encourages sex. That's just ignorant bullshit.
The best response to the problem (in a treatment environment) that I came across was to not allow the patient access to anything obvious that they may harm themselves with. The cutters would usually find something anyway and slice away (you'd be surprised how many could secretly get a hold of razor blade).
When found they would be treated and encouraged to talk about the incident and ways they could deal with things without cutting next time.
Attention to the cutting behavior was kept to a minimum, meaning no "Oh my God! You've cut yourself!" It was more of "Oh, you did some cutting, eh? Well, let's clean it up and go talk."
The cutting I saw was usually done by a razor blade, broken plastic or glass, or some piece of metal and the cutters usually took the time to clean their cutting object. Also, the less sensationalism paid to the cutting behavior, the less it occurred.
