The role of general practitioners in prevention of depression-related suicides

Suicide is a ubiquitous phenomenon present in every country, and a function of the constellation of multiple risk and protective factors. The relatively low occurrence of attempted and completed suicide in the general community makes its research and consequentially prediction and prevention difficult, however, suicide events are common among psychiatric patients who contact their general practitioners some weeks or months before their suicidal act. Major depressive episode is the most common current psychiatric diagnosis among suicide victims and attempters (56-87%), and successful acute and long-term treatment of depression significantly reduces the risk of suicidal behaviour even in this high-risk population. The point prevalence of unipolar and bipolar major depressive episode encountered in general practice is more than 10% but unfortunately about half of these cases remain unrecognized, untreated or mistreated. As over half of all suicide victims contact their general practitioners within four weeks before their death, primary care physicians play a key role in suicide prediction and prevention. Several large-scale community studies show that education of general practitioners and other medical professionals on the recognition and appropriate pharmacotherapy of depression, particularly in combination with psycho-social interventions and public education significantly improves identification and treatment of depression and consequentially reduces the rate of completed and attempted suicide in the areas served by trained doctors.
