Suicide in developing countries (2): risk factors.

The majority of studies on risk factors for suicide have been conducted in developed countries, and less work has been done to systematically profile risk factors in developing countries. The current paper presents a selective review of sociodemographic, clinical, and environmental/situational risk factors in developing countries. Taken together, the evidence suggests that the profiles of risk factors in developing countries demonstrate some differences from those in developed countries. In some developing countries, at least, being female, living in a rural area, and holding religious beliefs that sanction suicide may be of more relevance to suicide risk than these factors are in developed countries. Conversely, being single or having a history of mental illness may be of less relevance. Risk factors that appear to be universal include youth or old age, low socioeconomic standing, substance use, and previous suicide attempts. Recent stressful life events play a role in both developing and developed countries, although their nature may differ (e.g., social change may have more of an influence in the former). Likewise, access to means heightens risk in both, but the specific means may vary (e.g., access to pesticides is of more relevance in developing countries). These findings have clear implications for suicide prevention, suggesting that preventive efforts that have shown promise in developed countries may need to be tailored differently to address the risk factor profile of developing countries.

Effectiveness of a community-based intervention for people with schizophrenia and their caregivers in India (COPSI): a randomised controlled trial

Summary Background Observational evidence suggests that community-based services for people with schizophrenia can be successfully provided by community health workers, when supervised by specialists, in low-income and middle-income countries. We did the COmmunity care for People with Schizophrenia in India (COPSI) trial to compare the effectiveness of a collaborative community-based care intervention with standard facility-based care. Methods We did a multicentre, parallel-group, randomised controlled trial at three sites in India between Jan 1, 2009 and Dec 31, 2010. Patients aged 16–60 years with a primary diagnosis of schizophrenia according to the tenth edition of the International Classification of Diseases, Diagnostic Criteria for Research (ICD-10-DCR) were randomly assigned (2:1), via a computer-generated randomisation list with block sizes of three, six, or nine, to receive either collaborative community-based care plus facility-based care or facility-based care alone. Randomisation was stratified by study site. Outcome assessors were masked to group allocation. The primary outcome was a change in symptoms and disabilities over 12 months, as measured by the positive and negative syndrome scale (PANSS) and the Indian disability evaluation and assessment scale (IDEAS). Analysis was by modified intention to treat. This study is registered as an International Standard Randomised Controlled Trial, number ISRCTN 56877013. Findings 187 participants were randomised to the collaborative community-based care plus facility-based care group and 95 were randomised to the facility-based care alone group; 253 (90%) participants completed follow-up to month 12. At 12 months, total PANSS and IDEAS scores were lower in patients in the intervention group than in those in the control group (PANSS adjusted mean difference −3·75, 95% CI −7·92 to 0·42; p=0·08; IDEAS −0·95, −1·68 to −0·23; p=0·01). However, no difference was shown in the proportion of participants who had a reduction of more than 20% in overall symptoms (PANSS 85 [51%] in the intervention group vs 44 [51%] in the control group; p=0·89; IDEAS 75 [48%] vs 28 [35%]). We noted a significant reduction in symptom and disability outcomes at the rural Tamil Nadu site (−9·29, −15·41 to −3·17; p=0·003). Two patients (one in each group) died by suicide during the study, and two patients died because of complications of a road traffic accident and pre-existing cardiac disease. 18 (73%) patients (17 in the intervention group) were admitted to hospital during the course of the trial, of whom seven were admitted because of physical health problems, such as acute gastritis and vomiting, road accident, high fever, or cardiovascular disease. Interpretation The collaborative community-based care plus facility-based care intervention is modestly more effective than facility-based care, especially for reducing disability and symptoms of psychosis. Our results show that the study intervention is best implemented as an initial service in settings where services are scarce, for example in rural areas. Funding Wellcome Trust.

Collaborative community based care for people and their families living with schizophrenia in India: protocol for a randomised controlled trial

BackgroundThere is a large treatment gap with few community services for people with schizophrenia in low income countries largely due to the shortage of specialist mental healthcare human resources. Community based rehabilitation (CBR), involving lay health workers, has been shown to be feasible, acceptable and more effective than routine care for people with schizophrenia in observational studies. The aim of this study is to evaluate whether a lay health worker led, Collaborative Community Based Care (CCBC) intervention, combined with usual Facility Based Care (FBC), is superior to FBC alone in improving outcomes for people with schizophrenia and their caregivers in India.Methods/DesignThis trial is a multi-site, parallel group randomised controlled trial design in India.The trial will be conducted concurrently at three sites in India where persons with schizophrenia will be screened for eligibility and recruited after providing informed consent. Trial participants will be randomly allocated in a 2:1 ratio to the CCBC+FBC and FBC arms respectively using an allocation sequence pre-prepared through the use of permuted blocks, stratified within site. The structured CCBC intervention will be delivered by trained lay community health workers (CHWs) working together with the treating Psychiatrist. We aim to recruit 282 persons with schizophrenia. The primary outcomes are reduction in severity of symptoms of schizophrenia and disability at 12 months. The study will be conducted according to good ethical practice, data analysis and reporting guidelines.DiscussionIf the additional CCBC intervention delivered by front line CHWs is demonstrated to be effective and cost-effective in comparison to usually available care, this intervention can be scaled up to expand coverage and improve outcomes for persons with schizophrenia and their caregivers in low income countries.Trial registrationThe trial is registered with the International Society for the Registration of Clinical Trials and the allocated unique ID number is ISRCTN 56877013.

Telepsychiatry in Chennai, India: The SCARF experience

India, with its huge population and limited mental health resources, must find alternative ways of delivering its mental healthcare services. Telepsychiatry seems to be a promising option even with no regulatory authority in place or specific laws in India that deal with telemedicine practice, there has been a mushrooming of telemedicine services in India. Healthy cooperation between government organizations such as the Indian Space Research Organization (ISRO) and institutions in the non-government and private sectors is another key feature in India. The experience of the Schizophrenia Research Foundation (SCARF), at Chennai, in South India, in running and establishing a telepsychiatry network is presented in this article. We identified the following tasks as essential to ensure an efficient intervention using telemedicine: identifying a suitable technology, a suitable location, and a local collaborator; providing training and creating awareness; establishing peripheral telepsychiatry centers and ensuring case documentation; and accountability.

Community mental health in India: A rethink.

BackgroundCommunity care of the chronic mentally ill has always been prevalent in India, largely due to family involvement and unavailability of institutions. In the 80s, a few mental health clinics became operational in some parts of the country. The Schizophrenia Research Foundation (SCARF), an NGO in Chennai had established a community clinic in 1989 in Thiruporur, which was functional till 1999. During this period various programmes such as training of the primary health center staff, setting up a referral system, setting up of a Citizens Group, and self-employment schemes were initiated. It was decided to begin a follow up in 2005 to determine the present status of the schemes as well as the current status of the patients registered at the clinic. This we believed would lead to pointers to help evolve future community based programmes.MethodsOne hundred and eighty five patients with chronic mental illness were followed up and their present treatment status determined using a modified version of the Psychiatric and Personal History Schedule (PPHS). The resources created earlier were assessed and qualitative information was gathered during interviews with patient and families and other stakeholders to identify the reasons behind the sustenance or failure of these initiatives.ResultsOf the 185 patients followed up, 15% had continued treatment, 35% had stopped treatment, 21% had died, 12% had wandered away from home and 17% were untraceable. Of the patients who had discontinued treatment 25% were asymptomatic while 75% were acutely psychotic.The referral service was used by only 15% of the patients and mental health services provided by the PHC stopped within a year. The Citizens group was functional for only a year and apart from chicken rearing, all other self-employment schemes were discontinued within a period of 6 months to 3 years.There were multiple factors contributing to the failure, the primary reasons being the limited access and associated expenses entailed in seeking treatment, inadequate knowledge about the illness, lack of support from the family and community and continued dependence by the family on the service provider to provide solutions.ConclusionCommunity based initiatives in the management of mental disorders however well intentioned will not be sustainable unless the family and the community are involved in the intervention program with support being provided regularly by mental health professionals.

Psychosocial interventions after tsunami in Tamil Nadu, India.

Any response to the mental health needs of the affected community following any disaster depends upon a number of factors, including disaster preparedness, existence of mental health services, resources in human and financial terms, along with the magnitude, cause and suddenness of the event. In India, groups of islands in the Bay of Bengal and the coast of Tamil Nadu were very badly hit. The survivors needed basic physical and emotional support. The response by two non-governmental organizations (NGOs) is described in this paper. Normalization was seen as an important first step. Using a number of training materials, volunteers were trained to deal with the mental health needs of the survivors. A consistent well resourced and accessible mental health network is necessary for appropriate intervention.

Psychiatric advance statements: An Indian experience

Background: The psychiatric advance statement (PAS) is a document that outlines the preferences of patients in their future treatment. Formulating and writing a PAS has not been studied in low- and middle-income (LAMI) countries. Aim: To study the feasibility of writing a PAS in an Indian population. Methods: Patients’ diagnosed with schizophrenia or schizoaffective psychosis attending the outpatient clinic at the Schizophrenia Research Foundation (SCARF) or its community centres in 2011 were screened using the study criteria. After obtaining informed consent, stratified sampling was used to derive the final sample. Results: Most patients consented to participate in the study (122/123 patients). Following interviews with research assistants, 93 patients were assessed to have the capacity to write a PAS and 92 completed one. The patients were mostly able to complete the PAS on their own. Major themes included choice of treatment facility, type of treatment and nomination of others to take decisions on their behalf. A third of the sample were either from rural areas or not exclusively urban. At the time of the study, about 45% of the sample was rated as being symptomatic. Conclusion: Psychotic patients with a long-term illness, a third of them from non-urban areas, were able to write a valid PAS.

Searching for psychosis: INTREPID (1): systems for detecting untreated and first-episode cases of psychosis in diverse settings

PurposeOur understanding of psychotic disorders is largely based on studies conducted in North America, Europe and Australasia. Few methodologically robust and comparable studies have been carried out in other settings. INTREPID is a programme of research on psychoses in India, Nigeria, and Trinidad. As a platform for INTREPID, we sought to establish comprehensive systems for detecting representative samples of cases of psychosis by mapping and seeking to engage all professional and folk (traditional) providers and potential key informants in defined catchment areas.MethodWe used a combination of official sources, local knowledge of principal investigators, and snowballing techniques.ResultsThe structure of the mental health systems in each catchment area was similar, but the content (i.e., type, extent, and nature) differed. Tunapuna–Piarco (Trinidad), for example, has the most comprehensive and accessible professional services. By contrast, Ibadan (Nigeria) has the most extensive folk (traditional) sector. We identified and engaged in our detection system—(a) all professional mental health services in each site (in- and outpatient services—Chengalpet, 6; Ibadan, 3; Trinidad, 5); (b) a wide range of folk providers (Chengalpet, 3 major healing sites; Ibadan, 19 healers; Trinidad: 12 healers); and c) a number of key informants, depending on need (Chengalpet, 361; Ibadan, 54; Trinidad, 1).ConclusionsMarked differences in mental health systems in each catchment area illustrate the necessity of developing tailored systems for the detection of representative samples of cases with untreated and first-episode psychosis as a basis for robust, comparative epidemiological studies.

Experiences of stigma and discrimination faced by family caregivers of people with schizophrenia in India

Stigma associated with schizophrenia significantly affects family caregivers, yet few studies have examined the nature and determinants of family stigma and its relationship to their knowledge about the condition. This paper describes the experiences and determinants of stigma reported by the primary caregivers of people living with schizophrenia (PLS) in India. The study used mixed methods and was nested in a randomised controlled trial of community care for people with schizophrenia. Between November 2009 and October 2010, data on caregiver stigma and functional outcomes were collected from a sample of 282 PLS–caregiver dyads. In addition, 36 in-depth-interviews were conducted with caregivers. Quantitative findings indicate that ‘high caregiver stigma’ was reported by a significant minority of caregivers (21%) and that many felt uncomfortable to disclose their family members condition (45%). Caregiver stigma was independently associated with higher levels of positive symptoms of schizophrenia, higher levels of disability, younger PLS age, household education at secondary school level and research site. Knowledge about schizophrenia was not associated with caregiver stigma. Qualitative data illustrate the various ways in which stigma affected the lives of family caregivers and reveal relevant links between caregiver-stigma related themes (‘others finding out’, ‘negative reactions’ and ‘negative feelings and views about the self’) and other themes in the data. Findings highlight the need for interventions that address both the needs of PLS and their family caregivers. Qualitative data also illustrate the complexities surrounding the relationship between knowledge and stigma and suggest that providing ‘knowledge about schizophrenia’ may influence the process of stigmatisation in both positive and negative ways. We posit that educational interventions need to consider context-specific factors when choosing anti-stigma-messages to be conveyed. Our findings suggest that messages such as ‘recovery is possible’ and ‘no-one is to blame’ may be more helpful than focusing on bio-medical knowledge alone.

Design and clinical characteristics of a homogeneous schizophrenia pedigree sample from Tamil Nadu, India

Objective: The genetic complexity of schizophrenia may be compounded by the diagnostic imprecision inherent in distinguishing schizophrenia from closely related mood and substance use disorders. Further complexity may arise from studying genetically and/or environmentally diverse ethnic groups. Reported here are the ascertainment, demographic features and clinical characteristics, of a diagnostically and ethnically homogeneous schizophrenia pedigree sample from Tamil Nadu, India. Also reported is the theoretical power to detect genetic linkage in the subset of affected sibling pairs. Method: Affected sibling pair and trio pedigrees were identified by caste/ethnicity. Affected probands and siblings fulfilled DSM-IV criteria for schizophrenia or schizoaffective disorder. Results: The present sample consisted of 159 affected sibling pairs and 187 parent–offspring trios originating primarily from the Tamil Brahmin caste, but also incorporating pedigrees from genetically similar, geographically proximal caste groups. Consistent with previous studies in Tamil Nadu, a very low prevalence of affective psychoses such as schizoaffective disorder, was observed, with most affected individuals having schizophrenia (499/504). Also observed were extremely low rates of nicotine (12.4%), alcohol (1.1%) and illicit drug use (0%). Most affected individuals exhibited negative symptoms (>90%) and a severe, chronic course. All participants lived in the same geographic and climatic region and most affected individuals resided with close family members, increasing uniformity of the sociocultural environment. In affected sibling pairs, power to detect linkage to small-effect risk loci was modest, but this homogeneous sample may be enriched for loci of larger effect. Conclusions: This Indian schizophrenia sample exhibits diagnostic and ethnic homogeneity with high consistency of sociocultural environmental features. These characteristics should assist efforts to identify risk genes for schizophrenia.
