Cost-effectiveness of a helpline for suicide prevention

Health economic evaluation of preventive digital public health interventions using decision-analytic modelling: a systematized review

BACKGROUND

Digital public health (DiPH) provides novel approaches for prevention, potentially leading to long-term health benefits in resource-limited health systems. However, cost-effectiveness of DiPH interventions is unclear. This systematized review investigates the use of decision-analytic modelling in health economic evaluations of DiPH primary prevention and health promotion interventions, focusing on intervention's design, methods used, results, and reporting quality.

METHODS

PubMed, CINAHL, and Web of Science were searched for studies of decision-analytic economic evaluations of digital interventions in primary prevention or health promotion, published up to June 2022. Intervention characteristics and selected items were extracted based on the Consolidated Health Economic Evaluation Reporting Standards (CHEERS). Incremental cost-effectiveness ratios (ICERs) were then extracted and price-adjusted to compare the economic evaluation results. Finally, the included studies' reporting quality was assessed by building a score using CHEERS.

RESULTS

The database search (including search update) produced 2,273 hits. After removing duplicates, 1,434 titles and abstracts were screened. Of the 89 studies meeting the full-text search criteria, 14 were ultimately reviewed. The most common targets were physical activity (five studies) and weight loss (four). Digital applications include text messages, web-based inventions, app-based interventions, e-learning devices, and the promotion of smartphone apps. The mean ICER of the 12 studies using quality-adjusted life years (QALYs) is €20,955 per QALY (min. - €3,949; max. €114,211). The mean of reported CHEERS items per study is 81% (min. 59%; max. 91%).

CONCLUSIONS

This review only includes primary prevention and health promotion, and thus excludes other DiPH fields (e.g. secondary prevention). It also focuses on decision-analytic models, excluding study-based economic evaluations. Standard methods of economic evaluation could be adapted more to the specifics of DiPH by measuring the effectiveness of more current technologies through alternative methods, incorporating a societal perspective, and more clearly defining comparators. Nevertheless, the review demonstrates using common thresholds that the new field of DiPH shows potential for cost-effective preventive interventions.

Educating Crisis Supporters About Self-Harm and Suicide in Older Adults

OBJECTIVES

This study aimed to describe existing knowledge of crisis supporters (volunteers responding to crisis calls/texts/messages) regarding self-harm and suicide in older adults and investigate knowledge translation through use of a novel online adaptive learning tool.

METHODS

The online educational tool was tested in an Australian national sample of crisis supporters (trained volunteers) aged 18+. Knowledge Transfer was evaluated utilizing a pre/post intervention methodology for data collection. The collaboratively developed online educational tool comprised a pre-test (10 questions), middle learning module (individualised for participant's incorrect pre-test responses) and post-test (10 questions) on suicidal behaviours in older adults. Data analysed included the demographic characteristics of the participants, individual question scores, and summed pre- and post-tests scores. Group differences in change scores were assessed with either one-way between subjects ANOVA or independent samples t-test, depending on the number of groups within each variable. Pre-post education comparisons on individual change in scores were made using a paired samples t-test. Statistical significance was defined as p <0.05.

RESULTS

104 crisis supporters completed the tool (pre-test, middle lesson and post-test). There was significant improvement in knowledge of crisis supporters after the intervention (pre-test scores Mean (M) = 4.56, SD = 1.62 and post-test scores M = 7.61, SD = 1.60; t (103) = 17.242, p <0.001.).

CONCLUSION

Dedicated training about suicidal behaviors in older adults is needed given their high rates of suicide and differing underlying reasons and needs compared to younger adults.

Modelling in economic evaluation of mental health prevention: current status and quality of studies

BACKGROUND

The present study aimed to identify and critically appraise the quality of model-based economic evaluation studies in mental health prevention.

METHODS

A systematic search was performed on MEDLINE, EMBASE, EconLit, PsycINFO, and Web of Science. Two reviewers independently screened for eligible records using predefined criteria and extracted data using a pre-piloted data extraction form. The 61-item Philips Checklist was used to critically appraise the studies. Systematic review registration number: CRD42020184519.

RESULTS

Forty-nine studies were eligible to be included. Thirty studies (61.2%) were published in 2015-2021. Forty-seven studies were conducted for higher-income countries. There were mainly cost-utility analyses (n = 31) with the dominant primary outcome of quality-adjusted life year. The most common model was Markov (n = 26). Most of the studies were conducted from a societal or health care perspective (n = 37). Only ten models used a 50-year time horizon (n = 2) or lifetime horizon (n = 8). A wide range of mental health prevention strategies was evaluated with the dominance of selective/indicate strategy and focusing on common mental health problems (e.g., depression, suicide). The percentage of the Philip checkilst's criteria fulfilled by included studies was 69.3% on average and ranged from 43.3 to 90%. Among three domains of the Philip checklist, criteria on the model structure were fulfilled the most (72.1% on average, ranging from 50.0% to 91.7%), followed by the data domain (69.5% on average, ranging from 28.9% to 94.0%) and the consistency domain (54.6% on average, ranging from 20.0% to 100%). The practice of identification of 'relevant' evidence to inform model structure and inputs was inadequately performed. The model validation practice was rarely reported.

CONCLUSIONS

There is an increasing number of model-based economic evaluations of mental health prevention available to decision-makers, but evidence has been limited to the higher-income countries and the short-term horizon. Despite a high level of heterogeneity in study scope and model structure among included studies, almost all mental health prevention interventions were either cost-saving or cost-effective. Future models should make efforts to conduct in the low-resource context setting, expand the time horizon, improve the evidence identification to inform model structure and inputs, and promote the practice of model validation.

Suicide Ideation and Depression Quality of Life Ratings in a Reservation-Based Community of Native American Youths and Young Adults

Suicide among adolescents is a significant public health concern in the U.S., especially within American Indian and Alaska Native (AIAN) communities. Lack of quality of life (QoL) estimates for both suicide ideation and depression specific to the AIAN population hinders the ability to compare interventions in cost-effectiveness analysis. We surveyed 200 AI youth and young adults from the Fort Apache Indian Reservation to estimate utility weights for experiencing suicide ideation and depression. Our results indicate that, on a scale of 0-100, with higher scores indicating better health, the general community rates both suicide ideation and depression at 15.8 and 25.1, respectively. These weights are statistically significantly different and lower than for other cultures. Culturally specific QoL values will allow the comparison and identification of the most effective and feasible interventions to reduce the suicide burden among tribal communities.

The Development of an Online Training Tool for Crisis Supporters on Late Life Suicide: Improving Knowledge While Promoting Empowerment

Telephone crisis services have an increasing role in suicide prevention yet existing interventions have not empowered crisis supporters with adequate education targeting the needs of older people in crisis. An existing educational intervention was adapted for crisis supporters through collaboration between a crisis support service, clinician researchers, and an eLearning technology company. Empowering crisis supporters, through improving knowledge and highlighting their strengths and expertise, was emphasized. The adaptive learning technology featured a pretest, middle learning module (educational content), and post-test individualized to the participant's incorrect pretest answers. The online training tool on suicidal behaviors in late-life combined clinician researcher expertise and evidence, insights from crisis supporters, and adaptive learning technology to create a purpose-built educational tool addressing an unmet need.

What twitter can tell us about user experiences of crisis text lines: A qualitative study

Mental health problems are the leading cause of disability worldwide. Despite the prevalence and cost of mental illness, there are insufficient health services to meet this demand. Crisis hotlines have a number of advantages for addressing mental health challenges and reducing barriers to support. Mental health crisis services have recently expanded beyond telephone hotlines to include other communication modalities such as chat and text messaging services, largely in response to the increased use of mobile phones and text messaging for social communication. Despite the high uptake of crisis text line services (CTLs) and rising mental health problems worldwide, CTLs remain understudied. The current study aimed to address an urgent need to evaluate user experiences with text-based crisis services. This study explored user experiences of CTLs by accessing users' publicly available Twitter posts that describe personal use and experience with CTLs. Data were qualitatively analyzed using thematic analysis. Six main themes were identified from 776 tweets: (1) approval of CTLs, (2) helpful counselling, (3) invalidating or unhelpful counselling, (4) problems with how the service is delivered, (5) features of the service that facilitate accessibility, and (6) indication that the service suits multiple needs. Overall, results provide evidence for the value of text-based crisis support, as many users reported positive experiences of effective counselling that provided helpful coping skills, de-escalation, and reduction of harm. Results also identified areas for improvement, particularly ensuring more timely service delivery and effective communication of empathy. Text-based services may require targeted training to apply methods that effectively convey empathy in this medium. Moving forward, CTL services will require systematic attention in the clinical research literature to ensure their continued success and popularity among users.

Advancing Public Mental Health in Canada through a National Suicide Prevention Service: Setting an Agenda for Canadian Standards of Excellence

The Public Health Agency of Canada is funding a new Canada Suicide Prevention Service (CSPS), timely both in recognition of the need for a public health approach to suicide prevention, and also in the context of the COVID-19 pandemic, which is causing concern about the potential for increases in suicide. This editorial reviews priorities for suicide prevention in Canada, in relation to the evidence for crisis line services, and current international best practices in the implementation of crisis lines; in particular, the CSPS recognizes the importance of being guided by existing evidence as well as the opportunity to contribute to evidence, to lead innovation in suicide prevention, and to involve communities and people with lived experience in suicide prevention efforts.

Cost-effectiveness evidence of mental health prevention and promotion interventions: A systematic review of economic evaluations

BACKGROUND

The prevention of mental disorders and promotion of mental health and well-being are growing fields. Whether mental health promotion and prevention interventions provide value for money in children, adolescents, adults, and older adults is unclear. The aim of the current study is to update 2 existing reviews of cost-effectiveness studies in this field in order to determine whether such interventions are cost-effective.

METHODS AND FINDINGS

Electronic databases (including MEDLINE, PsycINFO, CINAHL, and EconLit through EBSCO and Embase) were searched for published cost-effectiveness studies of prevention of mental disorders and promotion of mental health and well-being from 2008 to 2020. The quality of studies was assessed using the Quality of Health Economic Studies Instrument (QHES). The protocol was registered with PROSPERO (# CRD42019127778). The primary outcomes were incremental cost-effectiveness ratio (ICER) or return on investment (ROI) ratio across all studies. A total of 65 studies met the inclusion criteria of a full economic evaluation, of which, 23 targeted children and adolescents, 35 targeted adults, while the remaining targeted older adults. A large number of studies focused on prevention of depression and/or anxiety disorders, followed by promotion of mental health and well-being and other mental disorders. Although there was high heterogeneity in terms of the design among included economic evaluations, most studies consistently found that interventions for mental health prevention and promotion were cost-effective or cost saving. The review found that targeted prevention was likely to be cost-effective compared to universal prevention. Screening plus psychological interventions (e.g., cognitive behavioural therapy [CBT]) at school were the most cost-effective interventions for prevention of mental disorders in children and adolescents, while parenting interventions and workplace interventions had good evidence in mental health promotion. There is inconclusive evidence for preventive interventions for mental disorders or mental health promotion in older adults. While studies were of general high quality, there was limited evidence available from low- and middle-income countries. The review was limited to studies where mental health was the primary outcome and may have missed general health promoting strategies that could also prevent mental disorder or promote mental health. Some ROI studies might not be included given that these studies are commonly published in grey literature rather than in the academic literature.

CONCLUSIONS

Our review found a significant growth of economic evaluations in prevention of mental disorders or promotion of mental health and well-being over the last 10 years. Although several interventions for mental health prevention and promotion provide good value for money, the varied quality as well as methodologies used in economic evaluations limit the generalisability of conclusions about cost-effectiveness. However, the finding that the majority of studies especially in children, adolescents, and adults demonstrated good value for money is promising. Research on cost-effectiveness in low-middle income settings is required.

Public awareness of the National Suicide Prevention Lifeline following the release of a hip-hop song

OBJECTIVE

In light of the current national mental health crisis, we use Google Trends, Twitter and data obtained from the National Suicide Prevention Lifeline to evaluate the effect of '1-800-273-8255' on public awareness for the National Suicide Prevention Lifeline.

DESIGN

Cross-sectional analysis.

MAIN OUTCOME MEASURES

We extracted data from Google Trends and Twitter for terms related to suicide following the release of Logic's song, '1-800-273-8255'. We then used a forecasting autoregressive integrated moving algorithm model to determine the greater than expected search interest.

RESULTS

Google searches for 'Suicide Hotline' increased 49% more than expected the day after Logic's song was released and sustained increase of queries resulted in an average relative search volume of 59.5%-9.1% higher than the mean forecasted value of 50.4% for the 28 days following the release. Tweets that engaged with the account '@800 273talk' on Twitter increased by 10 450% more than expected the day after the song was released and increased by a mean of 1497% greater than expected the week after the songs released.

CONCLUSION

Findings from our study suggest that the entertainment industry can play an important role in increasing awareness of hotline numbers. Logic's song provides an example of a positive influence on public health and provides support for further development and standards for proper awareness of suicide in the public view.

Emergency department mental health presentations before and during the COVID-19 outbreak in Western Australia

OBJECTIVE

Coronavirus (COVID-19) has led to high levels of psychological distress in the community. This study aimed to examine whether emergency departments (EDs) also recorded a rise in mental health presentations.

METHOD

Changes in the number, and type, of mental health presentations to Western Australia EDs were examined between January and May 2020, and compared to 2019.

RESULTS

Data showed an unexpected decrease in the number of mental health presentations, compared to 2019, which was temporally coincident with the rise in local COVID-19 cases. Presentations for anxiety and panic symptoms, and social and behavioural issues, increased by 11.1% and 6.5%, respectively, but suicidal and self-harm behaviours decreased by 26%.

CONCLUSION

A rise in local COVID-19 cases was associated with a decrease in mental health presentations to EDs. This has important implications for the planning and provision of healthcare services in the current pandemic.

Evaluating the Cost Effectiveness of a Suicide Prevention Campaign Implemented in Ontario, Canada

BACKGROUND

Although suicide-prevention campaigns have been implemented in numerous countries, Canada has yet to implement a strategy nationally. This is the first study to examine the cost utility of the implementation of a multidimensional suicide-prevention program that combines several interventions over a 50-year time horizon.

METHODS

We used Markov modeling to capture the dynamic changes to health status and estimate the incremental cost per quality-adjusted life-year gained over a 50-year period for Ontario residents for a suicide-prevention strategy compared to no intervention. The strategy consisted of a package of interventions geared towards preventing suicide including a public health awareness campaign, increased identification of individuals at risk, increased training of primary-care physicians, and increased treatment post-suicide attempt. Four health states were captured by the Markov model: (1) alive and no recent suicide attempt; (2) suicide attempt; (3) death by suicide; (4) death (other than suicide). Analyses were from a societal perspective where all costs, irrespective of payer, were included. We used a probabilistic analysis to test the robustness of the model results to both variation and uncertainty in model parameters.

RESULTS

Over the 50-year period, the suicide-prevention campaign had an incremental cost-effectiveness ratio (ICER) of $18,853 (values are in Canadian dollars) per QALY gained. In all one-way sensitivity analyses, the ICER remained under $50,000/QALY. In the probabilistic analysis, there was a probability of 94.8% that the campaign was cost effective at a willingness-to-pay of $50,000/QALY (95% confidence interval of ICER probabilistic distribution: 2650-62,375). Among the current population, the intervention was predicted to result in the prevention of 4454 suicides after 50 years (1033 by year 10; 2803 by year 25). A healthcare payer perspective sensitivity analysis showed an ICER of $21,096.14/QALY.

INTERPRETATION

These findings demonstrate that a suicide-prevention campaign in Ontario is very likely a cost-effective intervention to reduce the incidence of suicide and suggest suicide-prevention campaigns are likely to be cost effective for some other Canadian provinces and potentially other countries.

Changes in the number of suicide re-attempts in a French region since the inception of VigilanS, a regionwide program combining brief contact interventions (BCI)

BACKGROUND

Brief Contact Interventions (BCIs) after a suicide attempt (SA) are an important element of prevention against SA and suicide. They are easier to generalize to an entire population than other forms of intervention. VigilanS generalizes to a whole French region a BCI combining resource cards, telephone calls and mailings, according to a predefined algorithm. It was implemented gradually in the Nord-Pas-de-Calais (NPC), France, between 2015 and 2018. Here, we evaluate the effectiveness of VigilanS, in terms of SA reduction, using annual data collected by participating centers. Hypothesis tested: the higher the VigilanS implementation in a center (measured by penetrance), the greater the decrease in the number of SA observed in this center.

METHODS

The study period was from 2014 to 2018, across all of NPC centers. We performed a series of linear regressions, each center representing a statistical unit. The outcome was the change in the number of SA, relative to the initial number, and the predictive variable was VigilanS' penetrance: number of patients included in VigilanS over the total number of SA. Search for influential points (points beyond threshold values of 3 influence criteria) and weighted least squares estimations were performed.

RESULTS

Twenty-one centers were running VigilanS in 2018, with an average penetrance of 32%. A significant relationship was identified, showing a sharp decrease in SA as a function of penetrance (slope = - 1.13; p = 3*10^- 5). The model suggested that a 25% of penetrance would yield a SA decrease of 41%.

CONCLUSION

VigilanS has the potential to reduce SA. Subgroup analyzes are needed to further evaluate its effectiveness. Subgroup analyses remain to be done, in order to evaluate the specific variations of SA by group.

The Effectiveness of Crisis Line Services: A Systematic Review

Background: Crisis lines are a standard component of a public health approach to suicide prevention. Clinical aims include reducing individuals' crisis states, psychological distress, and risk of suicide. Efforts may also include enhancing access and facilitating connections to behavioral health care. This review examines models of crisis line services for demonstrated effectiveness. Methods: Literature searches of Medline, EMBASE, PsycINFO, Web of Science, CINAHL, Cochrane Library, and Google Scholar were conducted from January 1, 1990, to May 7, 2018. Experts were contacted, and references were mined for additional studies. Eligible studies provided health- or utilization-related effectiveness outcome(s). Results were graded according to the Oxford Centre for Evidence-Based Medicine and evaluated for risk of bias using the Effective Public Health Practice Project quality assessment tool for quantitative studies. Results: Thirty-three studies yielded effectiveness outcomes. In most cases findings regarding crisis calls vs. other modalities were presented. Evaluation approaches included user- and helper-reported data, silent monitoring, and analyses of administrative records. About half of studies reported immediate proximal outcomes (during the crisis service), and the remaining reported distal outcomes (up to four years post-contact). Most studies were rated at Oxford level four evidence and 80% were assessed at high risk of bias. Conclusions: High quality evidence demonstrating crisis line effectiveness is lacking. Moreover, most approaches to demonstrating impact only measured proximal outcomes. Research should focus on innovative strategies to assess proximal and distal outcomes, with a specific focus on behavioral health treatment engagement and future self-directed violence.

Chat-based hotlines for health promotion: a systematic review

BACKGROUND

Chat-based hotlines use online messaging services or popular chat applications such as WhatsApp, Facebook Messenger, and WeChat, to connect users to trained health providers or staff. Chat-based hotlines can provide real-time communication between health providers and patients.

METHODS

The evidence for chat-based hotlines for health promotion has not been reviewed systematically. Electronic databases (PubMed, Cochrane Database, Google Scholar) were searched to identify English-language studies describing original research published from 2009 to 2020. This review was registered with Prospero Register of Systematic Reviews (ID: CRD42020156670).

RESULTS

Twelve publications met our criteria. Ten studies reported on user characteristics, eight on comparing use of chat-based hotlines with different modes of support, six on health outcomes and six on user satisfaction. Included studies report that chat-based hotlines have been used primarily for crisis and emotional support in high-income countries. Chat-based hotlines using instant messenger applications were preferred over other modes of services such as email, text messaging, voice calls, and face-to-face counselling. Evaluations of health outcomes, although limited in rigor due to mostly observational study designs, indicate mostly positive and statistically significant effects on mental health outcomes such as anxiety, depression, well-being and suicidality. User satisfaction with chat-based hotlines were moderately high.

CONCLUSIONS

Chat-based hotlines may be effective ways to deliver crisis support services in high income settings. They may have the potential to be effective in low- and middle-income countries to expand the reach of mental health and crisis support services although such services have not yet been publicly evaluated.

Gender Differences in Risk Factors Related to Suicidal Ideation Among Callers to Telephone Helplines in Spain

The main goals of this study were to determine the prevalence rate of suicidal ideation among callers to a Spanish telephone general crisis helpline (Teléfono de la Esperanza) and to identify gender-based characteristics and risk factors related to suicidal ideation. A sample of 10,765 (6,868 men and 3,897 women) callers to this telephone helpline was assessed. ATENSIS, an assessment tool designed to collect information related to suicidal ideation among callers to telephone helplines, was used. Comparisons between men and women with suicidal ideation were carried out in all variables studied: sociodemographics, telephone call timing, risk factors, and suicidality. Of the total sample, 1.87% (n = 201) presented suicidal ideation, with a higher prevalence in women (2.80%) than in men (1.34%). Moreover, significant gender-based differences among callers with suicidal ideations were observed in some variables: women were older than men and showed a greater prevalence of chronic disease with pain; men showed a greater prevalence of depression, alcohol/drug abuse, helplessness, and lack of hope for the future. This study showed that telephone helplines can be used to identify suicidal ideation among callers. Moreover, gender-based differential characteristics among suicide ideators have been found. The implications for further research are discussed.

Relationship between suicidal ideation and family problems among young callers to the Japanese crisis hotline

Previous studies have reported an association between family relationships and suicidal behavior, and found that people with high suicidal ideation are not likely to consult with others about their distress. An effective consulting service is therefore necessary for such individuals. Crisis hotlines are effective for reducing suicide risk, but their associated suicide ideation rate and odds ratio of family problems children remain unclear. The present study investigated the suicidal ideation rate and odds ratio of callers under 20 years of age (N = 24,333) with family problems to the Japanese crisis hotline in 2012. There were 5,242 (21.5%), 18,061 (74.2%), and 1,030 (4.2%) calls related to family problems, other problems, and both, respectively. The suicidal ideation rate and odds ratio of callers with family problems were 2.2% and 0.426, respectively. This result suggested that callers with family problems have a significantly lower rate and odds ratio for suicidal ideation compared with others. However, some associations with a high suicide ideation rate were found for individual items among callers with family problems such as abuse (20.4%), family breakdown (16.1%), and domestic violence (10.6%). Further studies are needed to understand the suicidal ideation of callers with family problems and develop more effective preventive strategies.

Socio-demographic factors associated with choosing violent methods of suicide, 2011-2016, Ilam province

BACKGROUND

In new strategies towards of suicide prevention the best approach currently is based on specific method had specific risk factors. Therefore in this study we aimed to find out the association between socio-demographic factors and methods in completed suicide, 2011-2016, Ilam province.

METHODS

A cross-sectional study, 2011-2016, was conducted. A total of 540 completed suicides were recruited to the study. Data were collected by systematic registration suicide data (SRSD) and Legal Medicine Organization (LMO). After performs of descriptive statistics, to analysis of effects of each independent variable to the methods Multinomial Logistic Regression (MLR) was used, also adjusted odds ratio (AOR) was used to reporting of associations.

RESULTS

According to the result (55.8%) of deaths were occurred by hanging and self-immolation also a majority of suicides were occurred in females (60%). The important methods in males and females were hanging (70.6%) and self-immolation (72.8%), respectively. The self-immolation vs. others was significantly higher in cases that have mental disorders (AOR) = 2.05, 95% CI: 1.11, 3.78); also in cases with financial problem (AOR) = 2.70, 95% CI: 1.28, 5.71).

CONCLUSION

According to the finding age groups, gender, marital status, residence, and mental disorders are the important risk factors that effects on choosing of methods. Therefore consideration of this excess risk by this mentioned factors in prevention programs can be reducing the risk of death from suicide in society.

Quality Assessment of Economic Evaluations of Suicide and Self-Harm Interventions

Abstract. Background: Death following self-harm constitutes a major global public health challenge and there is an urgent need for governments to implement cost-effective, national suicide prevention strategies. Aim: To conduct a systematic review and quality appraisal of the economic evaluations of interventions aimed at preventing suicidal behavior. Method: A systematic literature search was performed in several literature databases to identify relevant articles published from 2003 to 2016. Drummond's 10-item appraisal tool was used to assess the methodological quality of the included studies. Results: In total, 25 documents encompassing 30 economic evaluations were included in the review. Of the identified evaluations, 10 studies were found to be of poor quality, 14 were of average quality, and six studies were considered of good quality. The majority of evaluations found the interventions to be cost-effective. Limitations: Several limitations were identified and discussed in the article. Conclusion: A notable few economic evaluations were identified. The studies were diverse, primarily set in high-income countries, and often based on modeling, emphasizing the need for more primary research into the topic. The discussion of suicide and self-harm prevention should be as nuanced as possible, including health economics along with cultural, social, and political aspects.

Characteristics of Telephone Crisis Hotline Callers with Suicidal Ideation in Japan

Hotline callers do not always have suicidal ideation and previous studies have noted that the rate of such callers is limited. Crisis hotline counselors must be able to identify high-risk callers in order to provide appropriate support. This study investigated the characteristics of Japanese crisis hotline callers in 2012 (N = 541,694) and is the first to analyze crisis hotline data for all parts of Japan over 1 year. About 14% of the callers had suicidal ideation and 6% had a history of attempted suicide. The odds ratio for suicidal ideation among those with a history of attempted suicide was 15.5. The suicidal ideation rate was much smaller compared to previous studies in other countries. There is a psychological barrier that must be broken for high-risk people to use support hotlines. In addition, attempted suicide is a strong exclusive predisposing factor for death due to suicide; therefore, counselors should pay careful attention to callers with a history of attempted suicide. The characteristics of Japanese crisis hotline callers and the features of suicidal ideation revealed in the present study are expected to be useful in developing telephone crisis hotline strategies.

Examination of the population attributable risk of different risk factor domains for suicidal thoughts and behaviors

BACKGROUND

Despite the fact that suicide is an important public health problem, the etiology is still not well understood. Especially lacking is a societal-level approach that takes into account the extent to which several risk factor domains are attributable to new onset of suicidal thoughts and behaviors (STB).

METHODS

Data stem from a cross-sectional population study of the non-institutionalized adult (18+) population from Belgium (N=2419). The third version of the Composite International Diagnostic Interview (CIDI-3.0) was administered to assess lifetime STB and risk factor domains. Multivariate approaches, expressed in population attributable risk proportions, were used to estimate the proportion of new onset cases of STB related to the occurrence of different risk factors.

RESULTS

Approximately 38% of cases of suicidal ideation onset were attributable to mental disorders, 20% to chronic physical conditions, and another 13% to parental psychopathology. Suicide attempts in the general population were attributable to mental disorders (PARP=48%), but attempts among persons with suicidal ideation were unrelated to mental disorders, but rather to trauma (PARP=17%) and childhood adversities (PARP=12%).

LIMITATIONS

This is an explorative study using multivariate additive general models that generates specific hypotheses on the development of STB onset rather than testing specific pathways in the process of STB.

CONCLUSIONS

New onset STB is mostly attributable to proximal risk factors such as mental disorders. However, distal risk factors like childhood adversities or trauma also play a considerable role in the new onset of STB, especially in the transition from suicide ideation to suicide attempt.

Suicide Prevention and Follow-Up Services: A Narrative Review

Previous suicide attempt is the most important predictor of death by suicide. Thus preventive interventions after attempting to suicide is essential to prevent reattempts. This paper attempts to determine whether phone preventive interventions or other vehicles (postal cards, email and case management) are effective in reattempt prevention and health promotion after discharge by providing an overview of studies on suicide reattempts. The research investigated in this review conducted from 1995 to 2014. A total of 26 cases related to the aim of this research were derived from 36 English articles with the aforementioned keywords Research shows that providing comprehensive aids, social support, and follow-up after discharge can significantly prevent suicide reattempts. Several studies showed that follow-up support (phone calls, crisis cards, mails, postal cards.) after discharge can significantly decrease the risk of suicide. More randomized controlled trials (RCT) are required to determine what factors of follow-up are more effective than other methods.

Cost-effectiveness analysis of pharmaceutical treatment options in the first-line management of major depressive disorder in Belgium

OBJECTIVE

The objective of this study was to assess the cost effectiveness of commonly used antidepressants as first-line treatment of major depressive disorder (MDD) in Belgium.

METHODS

The model structure was based on a decision tree developed by the Swedish TLV (Tandvårds- och läkemedelsförmånsverket) and adapted to the Belgium healthcare setting, using primary local data on the patterns of treatment and following KCE [Federal Knowledge Center (Federaal Kenniscentrum voor de Gezondheidszorg)] recommendations. Comparators were escitalopram, citalopram, fluoxetine, paroxetine, sertraline, duloxetine, venlafaxine, and mirtazapine. In the model, patients not achieving remission or relapsing after remission on the assessed treatment moved to a second therapeutic step (titration, switch, add-on, or transfer to a specialist). In case of failure in the second step or following a suicide attempt, patients were assumed to be referred to secondary care. The time horizon was 1 year and the analysis was conducted from the National Institute for Health and Disability Insurance (NIHDI; national health insurance) and societal perspectives. Remission rates were obtained from the TLV network meta-analysis and risk of relapse, efficacy following therapeutic change, risk of suicide attempts and related death, utilities, costs (2012), and resources were derived from the published literature and expert opinion. The effect of uncertainty in model parameters was estimated through scenario analyses and a probabilistic sensitivity analysis (PSA).

RESULTS

In the base-case analysis, escitalopram was identified as the optimal strategy: it dominated all other treatments except venlafaxine from the NIHDI perspective, against which it was cost effective with an incremental cost-effectiveness ratio of <euro>6,352 per quality-adjusted life-year (QALY). Escitalopram also dominated all other treatments from the societal perspective. At a threshold of <euro>30,000 per QALY and from the NIHDI perspective, the PSA showed that the probability of escitalopram being identified as the optimal strategy ranged from 61 % (vs. venlafaxine) to 100 % (vs. fluoxetine).

CONCLUSION

Escitalopram was associated with the highest probability of being the optimal treatment from the NIHDI and societal perspectives. This analysis, based on new Belgian clinical practice data and following KCE requirements, provides additional information that may be used to guide the choice of treatments in the management of MDD in Belgium.
