Training and development Respondents were presented with a scale from minimal to major training and development provision. Only 8% of respondents reported that there had been major initiatives to provide training and development (Figure 27). Figure 28 suggests, however, that there has been a decline in GP engagement with leadership in and around CCGs. Figure 20) have shown reason for an optimistic picture of clinical leadership in and around CCGs, Figure 28 shows a degree of pessimism. There was an overall view that GPs are now less engaged in leadership than they were previously. There was broad agreement that, increasingly, service redesign is being tackled above the CCG level and that co-ordinated commissioning across multiple CCGs was increasingly common.

Sociological factors have a profound effect on the rate of suicide. Thus, suicide is not simply a matter for mental health services. In 1970, Stengel identified the important risk factors as being male, older, widowed, single or divorced, childless, high density population, residence in big towns, a high standard of living, economic crisis, alcohol consumption, broken home in childhood, mental disorder, and physical illness. While many of these hold today, residence in the country has replaced “residence in big towns” and low socioeconomic status has replaced “a high standard of living”. Lists of risk factors have been gathered for decades, but, they have high sensitivity and low specificity, while suicide has a low base rate - leading to unmanageably large numbers of both false positives and false negatives. A Sydney based group has extremely robustly stated that risk categorization (using risk factors) plays little or no role in the prevention of suicide (Large and Ryan, 2014 a&b; Large et al, 2011 a&b). These authors recommend that patients with mental disorder and other suffering individuals should be closely examined and all possible treatment/assistance should be provided – it is the treatment/management of issues rather than the classification of risk which is helpful. Some recent studies reported certain factors playing a stronger role than mental disorder. Almeida et al (2012) examined the suicidal thoughts of older people, found social disconnectedness and stress accounted for a larger proportion of cases than the mood disorders. Park et al (2013) have emphasized the importance of strained family relationships and a tolerant attitude to suicide. Schneider et al (2013) have emphasized the importance of obesity, smoking and living alone and conclude, “Suicide prevention measures should not only subjects with mental disorders but also address other adverse conditions”. Some medically orientated groups make observations which encourage the belief that mental health professionals can prevent suicide. For example, a recent study (Beautrais, 2004) of people who had made a suicide attempt found that after 5 years, 6. The paper concludes, “These findings imply the need for enhanced follow-up, treatment, and surveillance of all patients making serious suicide attempts”. This argument is logical, but impractical; most services are already doing their best and there is little evidence that any form of therapy is effective and maintaining intensive follow-up for 5 years would be impossible (from many points of view). In another example (Burgess et al, 2000), “Data on patient and treatment characteristics were examined by three experienced clinicians” and they found that “20% of the suicides were considered preventable. An exemplary admission procedure does not stop the patient out on leave getting drunk or being rejected by a lover; it does not strengthen the last straw for that individual. Beck et al (1999) studied outpatients at high risk of suicide, people 100 times more likely to suicide than members of the general population. They found the suicide rate among this high risk population was only 0. Thus, to save one life, even in this high risk group, it would be necessary to provide infallible care, 24 hours per day to 500 people for one year. Also, the support offered would need to be in a form acceptable to each individual. Powell et al (2000) studied psychiatric inpatient suicide. They compared those who had suicided as inpatients with a control group and identified risk factors. However, they concluded, “Although several factors were identified that were strongly associated with suicide, their clinical utility is limited by sensitivity and specificity, combined with the rarity of suicide, even in this high-risk group”. Appleby et al (1999) conducted comprehensive analysis of 10 040 suicides. They found, “Most… (of the deceased)… were thought to have been at no or low immediate risk at the final contact”. Fahy et al (2004) asked 7 experienced mental health professionals to read the notes of 78 psychiatric patients, and attempt to predict which 39 had suicided. The readers considered all known suicide risk factors. The result was that these skilled clinicians did no better than chance. The authors state, “…these disappointing findings call into question the clinical utility of risk factor findings to date”. There have been a number of well resourced small studies, in which high risk groups have been given sustained attention with special counseling and additional support. In none of these was there a significant difference in outcome when the experimental was compared to a control group. Reviewing these studies, Gunnell and Frankel (1994) found, “No single intervention has been shown in a well conducted randomized controlled trial to reduce suicide”. Similar conclusions have recently been made with respect of suicide among young people (Robinson et al, 2010). To date, 5 men have completed suicide at Guantanamo prison camp. Even with the reputation of the most powerful nation in the world in the balance, in the most secure environment on the planet, and with all possible resources, suicide could not be indefinitely prevented. Hospital admission Not infrequently, following a suicide, there is criticism of mental health professionals and systems for failing to admit people to hospital or, having admitted them, failing to provide some particular service/supervision. Most psychiatrists, however, have known closely supervised patients who have suicided. Powell et al (2000) described their experience, “…two inpatients were under continuous observation. One of these two jumped through a window and deliberately cut his neck with the broken glass, the other ran to a railway line and was hit by a train. In response to budgetary constraints, admissions to psychiatric hospital in Fulton County Georgia, USA, had to be reduced. Over the same time period, the suicide rate of the county did not increase, but fell, from 12 to 10/100 000 (not statistically significant). Thus, ready admission to hospital does not improve the suicide rate of a general population. Another group admitted to hospital for their own safety are people with an episode of a disorder like major depressive disorder, who appear to be in some danger of suicide. The idea here is that hospital is a safe place where the mental disorder can be most efficiently treated. The Sydney based researchers mentioned above have put forward a revolutionary idea, “Nosocomial Suicide” - that psychiatric admission may increase the risk of suicide (Large et al, 2014). For some individuals, adverse aspects of psychiatric ward admission may include stigmatization, a sense of abandonment and heightened vulnerability. This idea needs close examination and may change psychiatric practice. The impact of suicide on others Impact on relatives and friends. There is surprisingly little standardized data on the effect of relatives and friends of those who suicide.
