Background: Many somatic disorders are complicated by depression and increase the risk of suicide. Little is known about whether antidepressants might reduce the suicidal risk in patients with somatic disorders. Methods: Data on diagnoses and antidepressant prescriptions were derived from the Social and Health Information System of the Friuli Venezia Giulia Region. Cases were all suicides that occurred in the region during the years 2003–2013 and were sex- and age-matched to controls from the general population. Conditional logistic regression analysis was used to assess the association between suicide and somatic disorders. Results: The suicide rate in Friuli Venezia Giulia decreased from 11.3 to 10.7 per 100,000 inhabitants during the years 2003–2013, however patients with somatic disorder had a three times increased risk of suicide. Elderly somatic patients' suicide risk was twice as high as younger patients. The risk increased from 2.6 to 9.8 times as the number of comorbid disorders increased from 1 to 4 and over. Although no significant risk of suicide in patients with somatic disorders was found when patients were adherent to antidepressants, only 11.5% of the suicides was adherent in the year prior to death. Conclusions: Medical illnesses and underlying depressive symptoms may have a synergy effect on the risk of suicide, particularly in older patients and in patients with multiple morbidities. Since medically ill subjects adherent to antidepressants did not showa significant risk of suicide, early identification and adequate treatment of depression in somatic patients should be considered in order to prevent suicide.

Abstract

Background: Many somatic disorders are complicated by depression and increase the risk of suicide. Little is known about whether antidepressants might reduce the suicidal risk in patients with somatic disorders. Methods: Data on diagnoses and antidepressant prescriptions were derived from the Social and Health Information System of the Friuli Venezia Giulia Region. Cases were all suicides that occurred in the region during the years 2003–2013 and were sex- and age-matched to controls from the general population. Conditional logistic regression analysis was used to assess the association between suicide and somatic disorders. Results: The suicide rate in Friuli Venezia Giulia decreased from 11.3 to 10.7 per 100,000 inhabitants during the years 2003–2013, however patients with somatic disorder had a three times increased risk of suicide. Elderly somatic patients' suicide risk was twice as high as younger patients. The risk increased from 2.6 to 9.8 times as the number of comorbid disorders increased from 1 to 4 and over. Although no significant risk of suicide in patients with somatic disorders was found when patients were adherent to antidepressants, only 11.5% of the suicides was adherent in the year prior to death. Conclusions: Medical illnesses and underlying depressive symptoms may have a synergy effect on the risk of suicide, particularly in older patients and in patients with multiple morbidities. Since medically ill subjects adherent to antidepressants did not showa significant risk of suicide, early identification and adequate treatment of depression in somatic patients should be considered in order to prevent suicide.
