The effect of assisted dying on suicidality: a synthetic control analysis of population suicide rates in Belgium

This study aimed to determine the changes in population suicide rates in Belgium before and after its 2002 policy using the synthetic control method (SCM) and generalized synthetic control method (GSCM). As comparisons we used additional European Union members that have not adopted these policies. GSCM showed an average annual suicide rate increase of 0.73 per 100,000 population (95% CI − 5.7 to 7.2;p = 0.80). Placebo testing based on the SCM analysis showed equal outcomes for Belgium and the comparisons. This study failed to show evidence of association between implementation of legislation legitimizing assisted dying and population suicide rates. The threat of suicide contagion has influen ced policy discussions in the past, but this study suggests that there is presently no indication for policy-makers to view suicide contagions as a concerning side effect of assisted dying legislation.
