Suicide is increasing world-wide and is now one of the three most common causes of death in the age group of 15-44 (SUPRE, WHO, 2007; MittendorferRutz et al., 2004). This increasing problem warrants the development of tailormade prevention strategies. To date, evidence on a wide range of intervention methods both within Public Health and the Health care sector is emerging (Mann et al., 2005; Mittendorfer-Rutz et al., 2004a). The public health strategies include restricting access to lethal means such as weapons and pesticides; responsible media reporting and educational programmes for the public, and populations at risk. The strategies focusing on health care include improved medical care, improved follow-up of patients with a suicidal history and education of general practitioners (GPs) in detecting and treating depression. A recently published review of suicide prevention strategies by Mann and colleagues (2005), concludes that education of primary care physicians and gatekeepers as well as interventions restricting access to lethal means both show promising results in reducing suicide rates (Mann et al., 2005).
Rationale for educational interventions at a primary health care levelEven though suicidal behaviour has a multifactorial ethiology, the majority of suicides are committed by people who suffer from some kind of mental illness. Lönnqvist et al. (1995) carried out psychological autopsies on all suicides committed in Finland during one year (a total of 1397 cases) and found that 93% of these cases could be diagnosed with some kind of psychiatric disorder.Out of these 66% were diagnosed as having suffered from depression. In a more recent review the same authors estimated that 29-88% of suicide victims were suffering from depression (Lönnqvist, 2000). Although 60-80% of cases of depression can be successfully treated (by medication and/or other types of therapy) the WHO estimates that only around 25% of cases are offered sufficient treat-ment. Lack of trained caregivers, lack of resources, low help-seeking behaviour and social stigma related to the disorder are identified as possible explanations (WHO, 2007).An international review by Luoma et al. from 2002 suggests that a majority of suicide victims (approximately 75%) were in contact with the primary health care within the year prior to suicide; while in contrast, only around 30% were in contact with the mental health service during that same period. This suggests that the primary health care is an appropriate arena in order to reach groups at risk. By improving the detection of depression and suicidal tendencies in such patients, suicidal outcomes should be able to be prevented.
Aims and questionsThe primary question being asked in this review is whether educational programmes targeting primary health care staff can be effective in preventing suicide and depression. Outcomes that are of interest for this purpose include changes in rates of completed suicide and suicide attempts as well as the reported occurrence of suicidal thoughts and depressive sym...
