Father is in and out of hospital with blood infection

I’m very estranged from my father due to his alcoholism and severe abuse when I was a teenager. When I was 17 my mother and I packed our things and left with my little sister to stay somewhere he didn’t know the location of and I’ve only seen him 4 times since then (33 now).

My dad never tried to mend the relationship and I think has continued drinking despite saying he’s not. He called me for the first time since I left 16 years ago to tell me he’s in and out of the hospital with a blood infection and that he can’t walk due to severe pain. Seems like maybe the infection won’t go away despite treatment.

Does anyone else have experience with this? Is this a common thing in late stage alcoholism? Is this the end for him? I feel like since he called he might think the end is near.
