Commentary on: Suicide prevention strategies revisited: 10-year systematic review.
Suicide prevention is a global imperative, with over 800 000 suicide deaths recorded per year,1 but national and regional prevention strategies vary greatly, as does the reliability of mortality records, which makes comparisons of data from different countries difficult.2 Suicide prevention is further complicated by persisting taboos surrounding mental health and, particularly, by the relatively rare prevalence of suicide deaths; thus, the effectiveness of prevention efforts is difficult to measure.
