Abstract
Objective: Healthcare services are potential interventions points before suicide. The aim of the current study was to explore whether mental health (MH) multimorbidity is associated with contact with healthcare services before suicide. Methods: A retrospective study was conducted using data from the Irish Probable Suicide Deaths Study (IPSDS), over the period 2015–2020. MH conditions were recorded on the basis of collateral information, including medical diagnosis or/and undiagnosed. The IPSDS cohort (n = 3625), comprising deaths given a coronial verdict of suicide and deaths on the balance of probabilities, was allocated to three mutually exclusive health groups: (a) no MH conditions, (b) one MH condition only, (c) two or more MH conditions (“MH multimorbidity”). Descriptive statistics (p ≤ 0.05) and binary logistic regression analyses with odds ratios (OR) and 95% CIs (p ≤ 0.01) are presented. Results: One fifth (20%) of the IPSDS cohort had MH multimorbidity, which was more prevalent among those aged 35–44 years. The unadjusted logistic regression analysis indicated that those with multimorbidity were significantly more likely to have contacted health services before suicide, compared to those with no MH conditions. This finding was substantially unchanged following adjustment for sex, age, and labor market position (OR = 12.170, 95% CI 9.595–15.437, p < .001) and in a sensitivity analysis restricted to a subset of deaths given a coronial verdict of suicide (OR = 12.728, 95% CI 9.635–16.814). Conclusions: Our findings suggest that those who experience MH multimorbidity and are in contact with health services should be targeted with tailor-made suicide prevention interventions.
