  • Dementia Risk Score for UK

    We are delighted to read the publication of a new dementia risk score for prediction of dementia up to 14 years. We congratulate the authors for incorporating almost all modifiable factors identified by the 2020 Lancet Commission on dementia prevention, management and care. Since the publication of the European Brain Health Guidelines earlier this year, memory clinic professionals in the UK have been desperately looking for a home grown tool. We hope to see an online training for using this clinical tool in the near future.

  • Dr

    We congratulate Oxford colleagues for publishing the UK Biobank Dementia Risk Score (UKBDRS) for predicting dementia up to 14 years in individuals aged 50-73 years. For NHS clinicians aspiring to enhance existing memory clinics by adding Brain Health Services, the UKBDRS is an extremely valuable clinical tool. We are in the process of piloting a basic Brain Health clinic in Hertfordshire where we will use UKBDRS for risk assessment and profiling. The authors claim to provide access to an online spreadsheet for risk calculation, but it failed to open. an accessible online link or a mobile app may help busy clinicians use this risk score more effectively.

  • Suicide prediction following self-harm: are new tools any better?

    Recent systematic reviews, clinical guidelines, and suicide prevention strategies suggest we should abandon the endeavour of using risk assessment to predict suicide and instead focus on clinical need. (1, 2) Does the recent carefully conducted paper by Fazel and colleagues mean that this advice should be overturned? We think not.

    At the turn of the century several of us were involved in developing risk tools for self-harm. Nearly two decades later, colleagues have used larger samples, novel methodology, and painstaking analysis to produce OxSATs. Of course, interpretation of how good tools are depends on multiple diagnostic accuracy statistics and clinical context. However, one accepted measure of overall performance is the ‘area under the curve’ (AUC).

    What is striking is that the AUC for predicting suicide in the 6 months after self-harm was nearly identical for OxSATs and the first generation scales (0.75 vs 0.71). (3, 4) What is perhaps even more striking is the very different interpretation of the findings. The authors of the recent study suggest OxSATs accurately predicts the risk of suicide whereas Steeg et al. concluded the opposite and suggested scales should not be used to determine treatment.

    What should we make of this discrepancy? In the end it perhaps comes down to what different researchers mean by ‘accurate’. A commonly used measure which may reflect real world utility is the positive predictive value (PPV) - of those rated as at...

  • Why "Alcohol Abuse" Needs to Go

    I read this paper with great interest. The finding that 29% of somatic deaths were alcohol-related warrants further investigation, especially since, as the authors state, alcohol contributes to other somatic causes of death (e.g., cancer, CVD) that, in this methodology, were not classified as alcohol-related.

    I would encourage the authors to refrain from using terms such as “alcohol abuse” as was used in this publication. While this term is ubiquitous in the alcohol literature, it perpetuates stigma toward individuals who have alcohol use disorder and/or drink alcohol at high-risk levels. Indeed, evidence has demonstrated that using words like “substance abuser” or “abuse” can lead to feelings that those who use alcohol and/or other drugs are to blame for their situation (1). Alternative terms such as “those drinking at high-risk levels” would be preferred (2).

  • Suicide risk factors and risk assessment – Authors' reply

    In our meta-analysis, we synthesised evidence on risk factors for suicide based on psychological autopsy studies [1]. We included data from 37 case-control studies and examined associations for 40 risk factors in 12,734 adults. Novel aspects are the inclusion of a wide range of risk factors across four domains – sociodemographic, family history, clinical, and life events – and quantitative methods to examine sources of heterogeneity.

    In their response, Soper and Large question one interpretation to the findings (rather than methods, analyses, or reporting) stating that consideration of risk factors and risk assessment has limited clinical utility. We think that this is a misreading of the evidence.

    First, assessing the risk of suicide and linking assessment to preventative measures is a central component of clinical care. We suggest that prediction models can assist in stratifying an individual’s suicide risk. One advantage of empirically derived prediction models over subjective clinical judgment is that they attempt to incorporate the relative strength of multiple risk factors and their interactions. In addition, subjective clinical judgement tends to be optimistic with an over-reliance on recent events [2]. Furthermore, risk assessment tools can improve consistency within and between clinical services. They can also raise the ceiling of expertise, particularly where high staff turnover and variations in training experience exist, and anchor decision-maki...

  • Real World Significance To Patients

    It is regrettable that BMJ Mental Health marks its transition from the Journal Evidence-based Mental Health with the publication of a paper that could, at best, be judged evidence-informed than evidence-based. The authors of the O’Driscoll et al (2023) paper make no acknowledgements of possible publication bias. But they work either for the NHS trusts or IAPT. Further NHS Trusts operate the IAPT services. They make no critical appraisal of their usage of IAPT’s chosen metric of recovery. There is no acknowledgement of works that cast serious doubts on the Services claimed 50% recovery rate, Capobianco et al (2023), Scott (2018).
    The O’Driscoll et al (2023) paper claims that CBT may be preferred to counselling for clients who have anxiety symptoms comorbid with depression. But the conclusions are built on sand in that:
    a) there can be no certainty that the subjects studied were depressed as there was no ‘gold standard’ diagnostic interview conducted. Instead reliance was placed on a psychometric test, PHQ-9
    b) there can be no certainty about comorbidity because of the absence of a diagnostic interview
    c) no fidelity checks were carried out to establish whether therapists were conducting CBT or counselling. Reliance was instead placed on therapists claims.
    d) no blind-raters were used to assess outcome
    e) there can be no certainty that the observed changes would not have happened anyway because of the absence of a credible attention co...

  • Comment on Favril et al.: Overstatement of the evidence for suicide risk assessment

    In a recent article Favril and associates report a systematic review and meta-analysis of risk factors for suicide derived from psychological autopsy studies that compared community samples of suicide decedents to living or deceased controls. 1 They found a range of risk factors that were, in retrospect, strongly statistically associated with suicide, including the presence of mental disorder (Odds Ratio (OR) = 13.1), depression (OR = 11.0), previous psychiatric treatment (OR = 10.1), previous self-harm (OR = 10.1), and previous suicide attempt (OR = 8.5). While acknowledging methodological weaknesses intrinsic to psychological autopsy studies, the authors maintain a position that “Identifying factors associated with suicide can improve risk stratification and help target interventions for high-risk groups” (p. 1). We consider this conclusion to be premature and fear the article will perpetuate a misplaced confidence in these risk factors as a basis for suicide risk assessment and clinical decision-making.

    Three problems deserve attention. First, more methodologically sound longitudinal studies show much weaker prospective associations between risk factors and suicide. For example, in 2017 Franklin and associates published a survey of 50 years of longitudinal research into factors associated with suicidal thoughts and behaviours, including suicide.2 The top five risk factors for suicide in the Franklin meta-analysis were previous psychiatric hospitalisation (OR = 3...

  • Simulation training to teach medical students skills in a psychosocial intervention for alcohol related harm.

    We applaud the article by Dr Neale (1) which highlights the importance of simulation training to teach communication skills in psychiatry. However, there was no reference to the role of simulation training in teaching medical students skills in addictive medicine.
    As a result of an increase in alcohol related harm in Israel over the last 20 years (2) and recommendations (3) for controlled and replicable studies in undergraduate medical education in alcohol and substance abuse, we studied the impact of a short term intervention on the knowledge of psychiatric aspects of alcohol amongst 4th and 5th year medical students (4). The intervention consisted of a powerpoint lecture on alcohol related harm to small groups of students, followed immediately by an active member of an alcoholics anonymous group wherever possible relating his story to the material in the lecture. After 2 weeks the same group of students participated in a structured simulation of a family doctor interviewing a female adolescent because of a concern that she suffered from alcohol related harm.
    The students who did not participate directly in the simulation were asked to provide constructive feedback to the student who simulated the primary care physician along the lines of motivational interviewing (Engaging the patient, Focussing on the goals of the meeting, Evoking "change talk" by the patient as a way of introducing behavioural change and Closure of the meeting while maintaining...

  • Brief advice good enough
    Sahoo Saddichha

    The review by Havard and colleagues [1] does not take into account the fact that brief advice, either oral or written, is good enough to bring about behavioral change. To have such a group as the control group is self-defeating. In fact, in an emergency department (ED) setting, where both emotions and tension run high, it would be futile to try and attempt other time-consuming interventions such as motivational interviewi...
