Healthcare utilisation prior to suicide in persons with alcohol use disorder: national cohort and nested case-control study.

ABSTRACT:

Background

Alcohol use disorder (AUD) is common and associated with increased risk of suicide.

Aims

To examine healthcare utilisation prior to suicide in persons with AUD in a large population-based cohort, which may reveal opportunities for prevention.

Method

A national cohort study was conducted of 6 947 191 adults in Sweden in 2002, including 256 647 (3.7%) with AUD, with follow-up for suicide through 2015. A nested case-control design examined healthcare utilisation among people with AUD who died by suicide and 10:1 age- and gender-matched controls.

Results

In 86.7 million person-years of follow-up, 15 662 (0.2%) persons died by suicide, including 2601 (1.0%) with AUD. Unadjusted and adjusted relative risks for suicide associated with AUD were 8.15 (95% CI
