Organ pathologies detected post-mortem in patients receiving opioid agonist treatment for opioid use disorder: a nation-wide 2-year cross-sectional study.

Among autopsied Norwegians who died during opioid agonist treatment in 2014 and 2015, two-thirds had more than two organ system diseases, despite their mean age of 48 years at the time of death. Older age was independently associated with at least one cardiovascular or renal pathology after adjusting for sex and body mass index.
