Tøllefsen IM, Helweg-Larsen K, Thiblin I, Hem E, Kastrup MC, Nyberg U, Rogde S, Zahl PH, Østevold G, Ekeberg Ø - BMJ Open (2015)

Bottom Line: Valid mortality statistics are important for healthcare planning and research.The reclassification comprised an assessment of the manner and cause of death as well as the level of certainty.Hence, reclassification did not increase the overall official suicide statistics of the 3 Scandinavian countries.

BMJOPEN2015009120F2: Reclassification of suicides in the Norwegian data set. First re-evaluation (1), and second re-evaluation (2). Agreement (blue slanted lines) in classification of manner of death between the Norwegian Cause of Death Register and the experts’ classification. Bars to the left of the vertical black line show the experts’ reclassifications (%) from suicides to undetermined, natural deaths and accidents. Bars to the right of the vertical black line show the experts’ reclassifications (%) of accidents and natural deaths to suicides.

Mentions: In total, there was 88% (range 54–100%) agreement in the classification of suicide deaths between the official mortality statistics and the experts’ reclassifications. The Norwegian expert coder was 100% in agreement with the Norwegian Cause of Death Register. Disagreement between the official mortality statistics and the experts’ reclassification was found in the reclassification of suicides as undetermined manner of death in 11% (range 0–44%) of the cases (figure 2). Among all cases registered as suicides in the mortality statistics, 1% (range 0–12%) were reclassified as accidents and 0.1% as natural deaths. The Danish psychiatrist and forensic pathologist reclassified 30 (44%) and 19 (27%) of the cases registered as suicides in the Cause of Death Register as undetermined deaths, respectively. The other experts reclassified 0–17% of suicides as undetermined deaths. In total, 2% (range 0–7%) of accidental deaths and 0.5% (range 0–1.5%) of natural deaths were reclassified as suicides.
