Sister still drinking despite consequences, any advice?

Hi. I had a liver transplant and am not a drinker. Never really was much of one except for college. My sister is 61 and recently divorced with two adult kids. Her drinking was the biggest factor in her divorce. She finally hit bottom in her family's eyes with a DUI and was too drunk to show up for her court date. Only a very good lawyer has kept her out of jail. She has also got drunk and fallen 3 times and has had 2 brain surgeries. Somehow minor enough to be shortly released. She somehow still lives to drink (in our eyes and behind everyone's back). Has had terrible fights and has cut off most of her sons, friends brothers, mom, etc. . Admits now she has a problem but still lies whenever her mouth opens and refuses inpatient or outpatient treatment. And continues to believe she can drink and "just cut down" despite 3 serious falls, two accidents , two brain surgeries, excetera in the last 6 months. My wife, brother , nephews, friends and I have strongly counseled her to get help before she kills herself or someone else. But she defies logic and insists she can live without treatment/help and has either broken off relations with or barely puts up with her circle of people. I know it has to be her decision and I (we) can't do it for her but any suggestions from you guys who have more experience in this topic than I do. Than you.
