For me as a doctor, it's an important intervention because suicide is the end result of many different illnesses. A lot of factors go into the final moment.
Being able to actually limit the means is one of the strongest pieces of evidence we have to actually decrease the number of people who die by suicide. For an individual, if I'm working with an individual, removing the means often allows me to keep them out of hospital for extended periods of time. It allows me to have more time to treat their mental illness, if they have one. Keeping them alive opens up a lot of options.
