Effectiveness of brief intervention and contact for suicide attempters: A randomized controlled trial in five countries
Objective: To determine whether brief intervention and contact is effective in reducing subsequent suicide mortality among suicide attempters in low and middle-income countries. Methods: Suicide attempters (n = 1867) identified by medical staff in the emergency units of eight collaborating hospitals in five culturally different sites (Campinas, Brazil; Chennai, India; Colombo, Sri Lanka; Karaj, Islamic Republic of Iran; and Yuncheng, China) participated, from January 2002 to October 2005, in a randomized controlled trial to receive either treatment as usual, or treatment as usual plus brief intervention and contact (BIC), which included patient education and follow-up. Overall, 91 completed the study. The primary study outcome measurement was death from suicide at 18-month follow-up. Findings: Significantly fewer deaths from suicide occurred in the BIC than in the treatment-as-usual group (0.2 versus 2.2, respectively; �2 = 13.83, P < 0.001). Conclusion: This low-cost brief intervention may be an important part of suicide prevention programmes for underresourced low-and middle-income countries

Suicide attempts, plans, and ideation in culturally diverse sites: The WHO SUPRE-MISS community survey
Background. The objectives were to assess thoughts about suicide, plans to commit suicide and suicide attempts in the community, to investigate the use of health services following a suicide attempt, and to describe basic socio-cultural indices of the community. Method. The community su rvey was one component of the larger WHO multisite intervention study on suicidal behaviours (SUPRE-MISS). In each site, it aimed at randomly selecting and interviewing at least 500 subjects of the general population living in the catchment area of the emergency department where the intervention component of the study was conducted. Communities of eight SUPRE-MISS sites (in Brazil, China, Estonia, India, Iran, South Africa, Sri Lanka, and Viet Nam) participated plus two additional sites from Australia and Sweden conducting similar surveys. Results. Suicide attempts (0·4-4·2), plans (1·11-5·6), and ideation (2·6-25·4) varied by a factor of 10-14 across sites, but remained mostly within the ranges of previously published data. Depending on the site, the ratios between attempts, plans, and thoughts of suicide differed substantially. Medical attention following a suicide attempt varied between 22 and 88 of the attempts. Conclusions. The idea of the suicidal process as a continuous and smooth evolution from thoughts to plans and attempts of suicide needs to be further investigated as it seems to be dependent on the cultural setting. There are indications, that the burden of undetected attempted suicide is high in different cultures; an improved response from the health sector on how to identify and support these individuals is needed. © 2005 Cambridge University Press
Do general practitioners and psychiatrists agree about defining cure from depression? The DEsCRIBE™ survey
BACKGROUND: This study aimed to document the outcome dimensions that physicians see as important in defining cure from depression. The study also aimed to analyse physicians' attitudes about depression and to find out whether they affect their prescribing practices and/or the outcome dimensions that they view as important in defining cure. METHODS: A 51-item questionnaire based on six validated scales was used to rate the importance of several depression outcome dimensions. Physicians' attitudes about depression were also assessed using the Depression Attitude Scale. Overall, 369 Belgian physicians (264 general practitioners [GPs]; 105 psychiatrists) participated in the DEsCRIBE survey. RESULTS: GPs and psychiatrists strongly agreed that functioning and depressive symptomatology were most important in defining cure; anxious and somatic symptomatology was least important. GPs and psychiatrists differed in their attitudes about depression (p <0.001). Logistic regression revealed that the attitudes of GPs - but not psychiatrists - were significantly associated with their rates of antidepressant prescription (p < 0.001) and that certain attitudes predicted which outcome dimensions were seen as important in defining cure. CONCLUSIONS: Belgian GPs and psychiatrists strongly agreed on which criteria were important in defining cure from depression but differed in their attitudes about depression. The outcome dimensions that were considered important in defining cure were influenced by physicians' attitudes - this was more pronounced in GPs than in psychiatrists
Characteristics of attempted suicides seen in emergency-care settings of general hospitals in eight low- and middle-income countries
Background. The objective was to describe patients presenting themselves at emergency-care settings following a suicide attempt in eight culturally different sites Campinas (Brazil), Chennai (India), Colombo (Sri Lanka), Durban (South Africa), Hanoi (Viet Nam), Karaj (Iran), Tallinn (Estonia), and Yuncheng, (China). Method. Subjects seen for su icide attempts, as identified by the medical staff in the emergency units of 18 collaborating hospitals were asked to participate in a 45-minute structured interview administered by trained health personnel after the patient was medically stable. Result s. Self-poisoning was the main method of attempting suicide in all eight sites. Self-poisoning by pesticides played a particularly important role in Yuncheng (71·6% females, 61·5% males), in Colombo (43·2% males, 19·6% females), and in Chennai (33·8% males, 23·8% females). The suicide attempt resulted in danger to life in the majority of patients in Yuncheng and in Chennai (over 65%). In four of the eight sites less than one-third of subjects received any type of referral for follow-up evaluation or care. Conclus ions. Action for the prevention of suicide attempts can be started immediately in the sites investigated by addressing the one most important method of attempted suicide, namely self-poisoning. Regulations for the access to drugs, medicaments, pesticides, and other toxic substances need to be improved and revised regulations must be implemented by integrating the efforts of different sectors, such as health, agriculture, education, and justice. The care of patients who attempt suicide needs to include routine psychiatric and psychosocial assessment and systematic referral to professional services after discharge. © 2005 Cambridge University Press
Intervention for depression among palliative care patients and their families: A study protocol for evaluation of a training program for professional care staff
Background: Clinical depression is highly prevalent yet under-detected and under-treated in palliative care settings and is associated with a number of adverse medical and psychological outcomes for patients and their family members. This article presents a study protocol to evaluate a training intervention for non-physician palliative care staff to improve the recognition of depression and provide support for depressed patients and their family members. Details of the hypotheses and expected outcomes, study design, training program development and evaluation measures are described.Methods and Design: A randomised controlled trial will be implemented across two palliative care services to evaluate the “Training program for professional carers to recognise and manage depression in palliative care settings”. Pre-, post- and three-month follow-up data will be collected to assess: the impact of the training on the knowledge, attitudes, self-efficacy and perceived barriers of palliative care staff when working with depression; referral rates for depression; and changes to staff practices. Quantitative and qualitative methods, in the form of self-report questionnaires and interviews with staff and family members, will be used to evaluate the effectiveness of the intervention.Discussion: This study will determine the effectiveness of an intervention that aims to respond to the urgent need for innovative programs to target depression in the palliative care setting. The expected outcome of this study is the validation of an evidence-based training program to improve staff recognition and appropriate referrals for depression, as well as improve psychosocial support for depressed patients and their family members.<br /
