Postcards from the EDge: 5-year outcomes of a randomised controlled trial for hospital-treated self-poisoning

Implementation of caring contacts using patient feedback to reduce suicide-related outcomes following psychiatric hospitalization

INTRODUCTION

Suicide risk is substantially elevated following discharge from a psychiatric hospitalization. Caring Contacts (CCs) are brief communications delivered post-discharge that can help to improve mental health outcomes.

METHOD

This three-phase, mixed-method quality-improvement study revised an existing CC intervention using iterative patient and community feedback. Inpatients (n = 2) and community members (n = 13) participated in focus groups to improve existing CC messages (phases 1 and 2). We piloted these messages among individuals with a suicide-related concern following discharge from an inpatient psychiatric hospitalization (n = 27), sending CCs on days 2 and 7 post-discharge (phase 3). Phase 3 participants completed mental health symptom measures at baseline and day 7, and provided feedback on these messages.

RESULTS

Phase 1 and 2 focus group participants indicated preferences for shorter, more visually appealing messages that featured personalized, recovery-focused content. Phase 3 participants demonstrated reductions in depressive symptoms at day-7 post-discharge (-6.4% mean score on Hopkins-Symptom-Checklist, -9.0% mean score on Entrapment-Scale). Most participants agreed that CC messages helped them feel more connected to the hospital and encouraged help-seeking behavior post-discharge.

CONCLUSION

This study supports the use of an iterative process, including patient feedback, to improve CC messages and provides further pilot evidence that CC can have beneficial effects.

Caring Letters Sent by a Clinician or Peer to At-Risk Veterans: A Randomized Clinical Trial

Importance

Caring letters is an evidence-based suicide prevention intervention in acute care settings, but its outcomes among individuals who contact a national crisis line have not previously been evaluated.

Objective

To examine the outcomes of the Veterans Crisis Line (VCL) caring letters intervention and determine whether there are differences in outcomes by signatory.

Design, Setting, and Participants

This parallel randomized clinical trial compared signatories of caring letters and used an observational design to compare no receipt of caring letters with any caring letters receipt. Participants included veterans who contacted the VCL. Enrollment occurred between June 11, 2020, and June 10, 2021, with 1 year of follow-up. Analyses were completed between July 2022 and August 2023.

Intervention

Veterans were randomized to receive 9 caring letters for 1 year from either a clinician or peer veteran signatory.

Main Outcomes and Measures

The primary outcome measure was suicide attempt incidence in the 12 months following the index VCL contact. Incidence of Veterans Health Administration (VHA) inpatient, outpatient, and emergency health care use were secondary outcomes. All-cause mortality was an exploratory outcome. Wilcoxon rank-sum tests and χ2 tests were used to assess the differences in outcomes among the treatment and comparison groups.

Results

A total of 102 709 veterans (86 942 males [84.65%]; 15 737 females [15.32%]; mean [SD] age, 53.82 [17.35] years) contacted the VCL and were randomized. No association was found among signatory and suicide attempts, secondary outcomes, or all-cause mortality. In the analysis of any receipt of caring letters, there was no evidence of an association between caring letters receipt and suicide attempt incidence. Caring letters receipt was associated with increased VHA health care use (any outpatient: hazard ratio [HR], 1.10; 95% CI, 1.08-1.13; outpatient mental health: HR, 1.19; 95% CI, 1.17-1.22; any inpatient: HR, 1.13; 95% CI, 1.08-1.18; inpatient mental health: HR, 1.14; 95% CI, 1.07-1.21). Caring letters receipt was not associated with all-cause mortality.

Conclusions and Relevance

Among VHA patients who contacted the VCL, caring letters were not associated with suicide attempts, but were associated with a higher probability of health care use. No differences in outcomes were identified by signatory.

Creating and evaluating the score to assess overdose: the OD score

BACKGROUND

During disasters (including epidemics such as coronavirus disease 2019), the capacity of emergency departments is exceeded, thereby hindering the administration of appropriate lifesaving measures. Furthermore, the number of overdose patients increases because of the stress overload during emergency situation. The fact that overdose patients are forced to be transported to medical facilities that do not typically treat them is becoming worrisome. Moreover, there is no definitive score for overdose. This study aimed to create a patient-specific scoring system to assess overdose.

METHODS

This was a retrospective single-center study. The evidence-based OD score was evaluated on a scale of 0-15. Further, logistic analysis and receiver operating characteristic (ROC) curve analysis were performed to evaluate the score.

RESULTS

Overall, 262 patients (including 118 overdose patients) receiving care at the intensive care unit of Japan's Teikyo University Hospital in 2021 were targeted. Regarding the total OD score, ROC analysis revealed a cutoff of 8 (area under the curve [AUC]: 0.99, 95% confidence interval [CI]: 0.980-0.997, sensitivity: 0.95, specificity: 0.95, p < 0.05), which was considered to indicate an overdose. Of the items evaluated in the OD score, the scenario at the location of the patient's discovery (adjusted odds ratio [AOR]: 16.8, 95% CI: 5.0-255.9, p = 0.002) and recent experience of mental anxiety (AOR: 55.7, 95% CI: 2.8-5399.5, p = 0.03) significantly predicted an overdose in multivariable logistic regression analysis. External validation revealed that the OD score could also identify overdose in patients treated in a cohort from 2022 (average cutoff: 8.6, average AUC: 1.0, p < 0.0001).

CONCLUSIONS

The OD score could accurately assess overdose patients. Medical facilities that do not frequently address overdose patients will benefit from the use of this score.

Qualitative Evaluation of a Caring Letters Suicide Prevention Intervention for the Veterans Crisis Line

OBJECTIVE

Suicide is a leading cause of death in the United States. This has prompted the U.S. surgeon general to issue a report describing actionable items to reduce suicide rates, including a recommendation to increase the use of the caring letters intervention. This intervention involves mailing brief, nondemanding messages of care. As part of the Department of Veterans Affairs' (VA's) efforts to reduce suicide rates among veterans, a caring letters project was developed for veterans who contact the Veterans Crisis Line (VCL). This article describes the results of qualitative interviews conducted to better understand the experiences of veterans who received caring letters.

METHODS

Beginning in 2020, all identifiable veterans who used Veterans Health Administration services and contacted the VCL received nine letters over 1 year, along with a list of mental health resources. Semistructured interviews (N=23) were conducted, and content analysis was used to identify veterans' perspectives and suggestions for improving the intervention.

RESULTS

Sixteen men and seven women participated (mean age=53 years). Feedback varied, with most participants reporting that receiving caring letters had a positive impact and others noting aspects that could be improved to enhance the intervention's caring intent. Some also reported that the letters helped them engage with community resources and made them more likely to seek VA care.

CONCLUSIONS

The caring letters intervention, received after contact with the VCL, was well received by participants. They described feeling appreciated, cared for, encouraged, and connected. The results of this study will inform future evaluation examining veteran outcomes.

"Keep up the messages, sometimes it was a lifesaver": Effects of cultural adaptation on a suicide prevention clinical trial in American Indian/Alaska Native communities

Suicide disproportionately affects many American Indian/Alaska Native (AI/AN) communities. Caring Contacts is one of the few suicide prevention interventions with demonstrated success in diverse populations, but its acceptability and effectiveness have not been evaluated in AI/AN communities. Using community-based participatory research (Phase 1), we conducted focus groups and semi-structured interviews with AI/AN adults, healthcare providers, and leaders in four communities to improve study design and maximize intervention acceptability and effectiveness for implementation in a randomized controlled trial (Phase 2). This paper describes how adaptations made during Phase 1 affected the acceptability, fit, and responsiveness of the study features to the communities' needs. Acceptability of the study procedures and materials in this community appears to be high, with 92% of participants indicating the initial assessment interview was a positive experience. Broadening eligibility criteria with regard to age and possession of a cellular device resulted in the recruitment of an additional 48% and 46% of participants, respectively. Inclusion of locally-informed methods of self-harm allowed us to capture a wider range of suicidal behavior than would have otherwise been identified. Clinical trials would benefit from community-engaged, cultural adaptation studies with populations in which the interventions would eventually be applied.

Culturally Adapting Caring Contacts for Suicide Prevention in Four Alaska Native and American Indian Communities

AIM

Despite substantial tribal, state, and federal effort, American Indian and Alaska Native (AI/AN) suicide rates have changed little in the last 30 years, prompting attention to new and innovative approaches to this persistent health disparity. Suicide prevention interventions with demonstrated success in other populations may be useful in AI/AN communities. Caring Contacts is a suicide prevention intervention that has been adapted and shown to reduce suicide ideation, attempts, and deaths in other populations.

CONCLUSION

Overall, AI/AN study participants in four diverse AI/AN communities endorsed the use of Caring Contacts for suicide prevention in their communities. Intervention adaptations for use in these communities centered primarily on message frequency and timing as well as expanding access to Caring Contacts. The results of this study may be applicable to other populations that experience suicide-related health disparities.

METHODS

We used a community-based participatory research approach to gather qualitative data from community members, healthcare providers, and leaders in four AI/AN communities. These data were analyzed thematically and used to adapt Caring Contacts for use in a subsequent clinical trial with AI/AN people at high risk for suicide.

RESULTS

A total of 189 community members and other health system stakeholders in four tribal communities participated in focus groups and interviews. Caring Contacts was perceived in all communities to be acceptable. Feedback for intervention adaptations focused on the themes of trial eligibility criteria; instruments; message frequency, timing, and content; and cultural considerations.

Caring Texts, a strength-based, suicide prevention trial in 5 native communities: Research design and methods

BACKGROUND

Despite their intrinsic strengths and resilience, some American Indian and Alaska Native (AI/AN) communities experience among the highest rates of suicide of any racial and ethnic group. Caring Contacts is one of the only interventions shown to reduce suicide in clinical trials, but it has not been tested in AI/AN settings.

OBJECTIVE

To compare the effectiveness of Enhanced Usual Care (control) to Enhanced Usual Care augmented with a culturally adapted version of Caring Contacts (intervention) for reducing suicidal ideation, suicide attempts, and suicide-related hospitalizations.

METHODS

We are implementing a single blind randomized controlled trial of Caring Contacts in five AI/AN communities across the country (South Dakota, Montana, Oklahoma, and Alaska). Eligible participants have to be (1) actively suicidal or have made a suicide attempt within the past year; (2) at least 18 years of age; (3) AI/AN; (4) able to speak and read English; (5) able to participate voluntarily; (6) willing to be contacted by text, email or postal mail; and (7) able to provide consent. Following consent and baseline assessment, participants are randomized to receive either Enhanced Usual Care alone, or Enhanced Usual Care with 12 months (25 messages) of culturally adapted Caring Contacts. Follow-up assessments are conducted at 12 and 18 months.

CONCLUSIONS

If effective, this study of Caring Contacts will inform programs to reduce suicide in the study communities as well as inform future research on Caring Contacts in other tribal settings. Modifications to continue the trial during the COVID-19 pandemic are discussed.

Differences in overdose deaths by intent: Unintentional & suicide drug poisonings in North Carolina, 2015-2019

Comprehensive fatal overdose prevention requires an understanding of the fundamental causes and context surrounding drug overdose. Using a social determinants of health (SDOH) framework, this descriptive study examined unintentional and self-inflicted (i.e., suicide) overdose deaths in North Carolina (NC), focusing on specific drug involvement and contextual factors. Unintentional and suicide overdose deaths were identified using 2015-2019 NC death certificate data. Specific drug involvement was assessed by searching literal text fields for drug mentions. County-level contextual factors were obtained from NC Institute of Medicine and County Health Rankings, encompassing five SDOH domains (economic stability, social/community context, health care access/quality, education access/quality, neighborhood/built environment). Descriptive statistics were calculated by intent for drug involvement and a variety of contextual factors. During 2015-2019, 9% of NC drug overdose deaths were self-inflicted and 89% were unintentional (2% other/undetermined). Unintentional overdoses largely involved illicit drugs [fentanyl (47%), cocaine (33%), heroin (29%)]. Suicide overdoses frequently involved prescription opioids [oxycodone (18%), hydrocodone (10%)] and antidepressants (32%). Overall, overdose deaths tended to occur in under-resourced counties across all SDOH domains, though unintentional overdoses occurred more often among residents of under-resourced counties than suicide overdoses, with differences most pronounced for economic stability-related factors. There are notable distinctions between unintentional and suicide overdose deaths in demographics and drug involvement, though the assessment of SDOH demonstrated that overdose mortality is broadly associated with marginalization across all domains. These findings highlight the value of allocating resources to prevention and intervention approaches that target upstream causes of overdose (e.g., housing first, violence prevention programs).

Effectiveness of distance-based suicide interventions: multi-level meta-analysis and systematic review

BACKGROUND

The use of distance-based interventions (DBIs) to reduce suicidal ideation and behaviours are an increasingly relevant form of intervention. DBIs are more affordable, scalable and available than traditional face-to-face interventions, helping to narrow the gap between needed and provided care.

AIMS

To evaluate the overall effectiveness of DBIs against suicidal ideation and behaviours.

METHOD

We systematically searched Web of Science, Scopus and PubMed for all DBIs primarily aimed at reducing suicidal ideation and behaviours. Data were analysed with a robust variance estimation corrected, multi-level meta-analysis.

RESULTS

We found 38 studies, reporting 110 outcomes. Effectiveness in reducing suicidal ideation was low (standardised mean difference -0.174, 95% CI -0.238 to -0.110). DBIs were significantly less effective against suicidal behaviours than against suicidal ideation, although still effective (standardised mean difference -0.059, 95% CI -0.087 to -0.032). Human involvement had no significant effect on effectiveness.

CONCLUSIONS

Despite low effectiveness, DBIs might play a role in large-scale prevention efforts against suicidal ideation within a stepped care approach. Further, DBIs may be helpful in expanding mental health services in low- and middle-income countries with otherwise limited access to mental healthcare. Although the evidence for DBIs efficacy is well grounded, the technical and scientific evaluation of DBIs regarding their set up, functionality and components needs to be addressed in future studies.

Conceptualizing Suicide Prevention in Firefighters Through the lens of the Interpersonal-Psychological Theory of Suicide: A Narrative Review

Suicide is the 10th leading cause of death in the United States and is a significant public health problem. Suicide has also become a major concern among career American firefighters with rates for suicidal ideation and attempts in firefighters two to three times higher than rates in the general population. Firefighter suicide and mental health are major issues facing fire service leaders, mental health professionals, and most recently suicide experts. Despite an increased focus on understanding suicide in the fire service, there is little empirical evidence on the effectiveness of prevention in this population. The juxtaposition of elevated suicide rates with a dearth of empirical prevention data specific to firefighters warrants new approaches and conceptualizations of suicide prevention in this population. Grounded in the framework of the interpersonal-psychological theory of suicide (IPTS), this narrative review integrates select relevant firefighter specific suicide risk/protective factors and multi-level intervention/prevention literature to provide a structured approach to identifying current suicide intervention/prevention efforts with promising transportability to firefighters. Several recommendations for future intervention research specific to firefighters are also proposed.

Risk of suicide after a self-poisoning episode: a self-controlled case series study

PURPOSE

The risk of death from suicide after self-poisoning has been known to be significantly higher as compared to the general population. Nevertheless, the change in suicide risk before and after self-poisoning is still unclear.

METHODS

The database of territory-wide medical records collected by the Hospital Authority of Hong Kong was used to identify inpatients who have survived the first-ever self-poisoning but died by suicide between January 1, 2001, and December 31, 2010. A self-controlled case series ("SCCS") design controlling for time-invariant patient confounders was used to explore the temporal change in suicide risk after the first self-poisoning episode.

RESULTS

During the study period, 227 people in the database died from suicide after surviving one episode of self-poisoning. A significant increase of the risk of suicide in the first 12 months after the first lifetime self-poisoning-Risk Ratio ("RR") 2.88 (95% CI 1.74-4.76)-was detected. The RR gradually returned to baseline levels after the second post-poisoning period.

CONCLUSION

By within-person comparison, the net increase of the suicide risk caused by the first self-poisoning was quantitatively modeled, demonstrating that the first lifetime self-poisoning event itself is a modifiable risk factor of subsequent suicide death.

Designed and created for a veteran by a veteran: A pilot study of caring cards for suicide prevention

INTRODUCTION

This pilot study investigates feasibility and acceptability of Caring Cards, a suicide prevention intervention inspired by Caring Contacts and the Recovery Model, where Veteran peers create cards that are sent to Veterans recently discharged from a VA psychiatric hospitalization for suicide risk.

METHODS

Caring Cards consists of: (1) a weekly outpatient group where Veterans (card makers) create cards, and (2) sending cards to recently discharged Veterans (card recipients). Feasibility for card makers was measured by attendance; acceptability (satisfaction) was examined. Card recipients were sent one caring card, one week post-discharge. Feasibility for recipients was measured by the percentage of Veterans that met eligibility and follow-up response rate; acceptability (satisfaction) was examined.

RESULTS

Caring Cards is feasible and acceptable. The outpatient group had a higher attendance rate (81%) compared with other clinic groups. The percentage of eligible card recipients was 61%. Of these, 69% were reached for follow-up and 50% provided follow-up responses. Card makers and recipients both expressed positive experiences with Caring Cards.

CONCLUSION

Caring Cards is a low-intensity, feasible, and acceptable intervention with potential benefits for both Veteran card makers and recipients. Additional research is needed to determine the efficacy of Caring Cards as a suicide prevention intervention.

Effectiveness of assertive case management for patients with suicidal intent

The aim of this study was to examine the effectiveness of assertive case management intervention in preventing suicidal behaviour in self-poisoning patients. We conducted a secondary analysis of data from the ACTION-J study. Participants were self-poisoning patients with clear suicide intent admitted to emergency departments and with a primary psychiatric diagnosis (as per DSM-IV-TR axis 1). Patients were randomly assigned either to assertive case management or enhanced usual care. The primary outcome measure was the incidence of a first recurrent suicide attempt within 6 months. This study is registered at ClinicalTrials.gov (NCT00736918) and UMIN-CTR (C000000444). There were 297 self-poisoning patients in the intervention group and 295 in the control group. The primary outcome was significantly lower in the intervention group than in the control group. The incidence of a first recurrent suicide attempt within 1 and 3 months was also significantly lower in the intervention group, as was the number of overall self-harm episodes over the entire study period. Furthermore, the number of non-suicidal self-harm episodes and suicide attempts was significantly lower in the intervention group. Assertive case management is effective when promptly introduced in a hospital setting as an intervention following a suicide attempt, particularly for self-poisoning patients.

Study designs and outcomes used in evaluation studies of hospital-presenting self-harm: protocol for a methodological systematic review

INTRODUCTION

Self-harm is the most common risk factor for suicide, and so those who present to hospital following self-harm provide an opportunity for targeted clinical care interventions. Observational studies evaluating such interventions may be useful in overcoming limitations of controlled trials, but study design, statistical analyses and outcomes used must be appropriate. This methodological systematic review will describe, categorise, synthesise and compare the methodological aspects of studies evaluating interventions and aspects of clinical management following hospital-presenting self-harm in both observational and experimental (ie, controlled trials or quasi-experimental studies) study designs.

METHODS AND ANALYSIS

Preferred Reporting Items for Systematic Reviews and Meta-Analysis-Protocol guidelines were followed in drafting this protocol. Search terms were developed (related to self-harm, hospital presentation and evaluation studies) and adapted for MEDLINE, PsycINFO, EMBASE, CINAHL, Cochrane Central Register of Controlled Trials and grey literature databases. Two reviewers will independently screen 100 titles/abstracts until consensus is reached, with the remaining screened by one reviewer. Full-text screening will be conducted independently by two reviewers. Data will be extracted by one reviewer, and a second will check all data extracted. Validated risk of bias tools will be used. Data synthesis will focus on the heterogeneity of outcomes used in individual studies. Descriptive summary statistics of the data (eg, key study characteristics, type and frequency of outcomes) will be provided in categorical format, using frequencies and percentages. Outcomes will be reported separately for trials (both randomised and non-randomised trials), observational and quasi-experimental studies. Categorisation of outcomes will be guided by Cochrane Effective Practice and Organisation of Care resources for reviews of health systems interventions.

ETHICS AND DISSEMINATION

Results will be disseminated at national and international conferences and published in a peer-reviewed journal. Findings will be used to inform future studies in the area of hospital-presenting self-harm. Ethical approval is not required for this review.

Accuracy Requirements for Cost-effective Suicide Risk Prediction Among Primary Care Patients in the US

Importance

Several statistical models for predicting suicide risk have been developed, but how accurate such models must be to warrant implementation in clinical practice is not known.

Objective

To identify threshold values of sensitivity, specificity, and positive predictive value that a suicide risk prediction method must attain to cost-effectively target a suicide risk reduction intervention to high-risk individuals.

Design, Setting, and Participants

This economic evaluation incorporated published data on suicide epidemiology, the health care and societal costs of suicide, and the costs and efficacy of suicide risk reduction interventions into a novel decision analytic model. The model projected suicide-related health economic outcomes over a lifetime horizon among a population of US adults with a primary care physician. Data analysis was performed from September 19, 2019, to July 5, 2020.

Interventions

Two possible interventions were delivered to individuals at high predicted risk: active contact and follow-up (ACF; relative risk of suicide attempt, 0.83; annual health care cost, $96) and cognitive behavioral therapy (CBT; relative risk of suicide attempt, 0.47; annual health care cost, $1088).

Main Outcomes and Measures

Fatal and nonfatal suicide attempts, quality-adjusted life-years (QALYs), health care sector costs and societal costs (in 2016 US dollars), and incremental cost-effectiveness ratios (ICERs) (with ICERs ≤$150 000 per QALY designated cost-effective).

Results

With a specificity of 95% and a sensitivity of 25%, primary care-based suicide risk prediction could reduce suicide death rates by 0.5 per 100 000 person-years (if used to target ACF) or 1.6 per 100 000 person-years (if used to target CBT) from a baseline of 15.3 per 100 000 person-years. To be cost-effective from a health care sector perspective at a specificity of 95%, a risk prediction method would need to have a sensitivity of 17.0% or greater (95% CI, 7.4%-37.3%) if used to target ACF and 35.7% or greater (95% CI, 23.1%-60.3%) if used to target CBT. To achieve cost-effectiveness, ACF required positive predictive values of 0.8% for predicting suicide attempt and 0.07% for predicting suicide death; CBT required values of 1.7% for suicide attempt and 0.2% for suicide death.

Conclusions and Relevance

These findings suggest that with sufficient accuracy, statistical suicide risk prediction models can provide good health economic value in the US. Several existing suicide risk prediction models exceed the accuracy thresholds identified in this analysis and thus may warrant pilot implementation in US health care systems.

Suicidality Over the First 5 Years of Psychosis: Does Extending Early Intervention Have Benefits?

OBJECTIVE

We aimed to investigate whether individuals with first-episode psychosis (FEP) receiving extended early intervention (EI) were less likely to experience suicidal ideation and behaviors than those transferred to regular care after 2 years of EI. Another objective was to examine the 5-year course of suicidality in FEP.

METHODS

We conducted a secondary analysis of a randomized controlled trial where 220 patients were randomized after 2 years of EI to receive extended EI or regular care for the subsequent 3 years. Suicidality was rated using the Brief Psychiatric Rating Scale. Linear mixed model analysis was used to study time and group effects on suicidality.

RESULTS

Extended EI and regular care groups did not differ on suicidality. There was a small decrease in suicidality over time, F(7, 1038) = 1.84, P = 0.077, with an immediate sharp decline within a month of treatment, followed by stability over the remaining 5 years. Patients who endorsed suicidality at entry (46.6%) had higher baseline positive, negative, and depressive symptoms. The 5-year course fell in 3 groups: never endorsed suicidality (33.9%), endorsed suicidality at low-risk levels (43.1%), and endorsed high-risk levels (23.0%). The high-risk group had a higher proportion of affective versus nonaffective psychosis diagnosis; higher baseline positive and depressive symptoms; higher 5-year mean depression scores, and fewer weeks of positive symptom remission over the 5-year course.

CONCLUSIONS

The first month of treatment is a critical period for suicide risk in FEP. Although early reductions in suicidality are often maintained, our findings make the case for sustained monitoring for suicide risk management.

Contacts with Health Services During the Year Prior to Suicide Death and Prevalent Conditions A Nationwide Study

BACKGROUND

This study was designed to describe contacts with health services during the year before suicide death in France, and prevalent mental and physical conditions.

METHODS

Data were extracted from the French National Health Data System (SNDS), which comprises comprehensive claims data for inpatient and outpatient care linked to the national causes-of-death registry. Individuals aged ≥15 years who died from suicide in France in 2013-2015 were included. Medical consultations, emergency room visits, and hospitalisations during the year preceding death were collected. Conditions were identified, and standardised prevalence ratios (SPRs) were estimated to compare prevalence rates in suicide decedents with those of the general population.

RESULTS

The study included 19,144 individuals. Overall, 8.5% of suicide decedents consulted a physician or attended an emergency room on the day of death, 34.1% during the week before death, 60.9% during the month before death. Most contacts involved a general practitioner or an emergency room. During the month preceding suicide, 24.4% of individuals were hospitalised at least once. Mental conditions (36.8% of cases) were 7.9-fold more prevalent in suicide decedents than in the general population. The highest SPRs among physical conditions were for liver/pancreatic diseases (SPR=3.3) and epilepsy (SPR=2.7).

LIMITATIONS

The study population was restricted to national health insurance general scheme beneficiaries (76% of the population living in France).

CONCLUSIONS

Suicide decedents have frequent contacts with general practitioners and emergency departments during the last weeks before death. Improving suicide risk identification and prevention in these somatic healthcare settings is needed.

Artificial Intelligence and Suicide Prevention: A Systematic Review of Machine Learning Investigations

Suicide is a leading cause of death that defies prediction and challenges prevention efforts worldwide. Artificial intelligence (AI) and machine learning (ML) have emerged as a means of investigating large datasets to enhance risk detection. A systematic review of ML investigations evaluating suicidal behaviors was conducted using PubMed/MEDLINE, PsychInfo, Web-of-Science, and EMBASE, employing search strings and MeSH terms relevant to suicide and AI. Databases were supplemented by hand-search techniques and Google Scholar. Inclusion criteria: (1) journal article, available in English, (2) original investigation, (3) employment of AI/ML, (4) evaluation of a suicide risk outcome. N = 594 records were identified based on abstract search, and 25 hand-searched reports. N = 461 reports remained after duplicates were removed, n = 316 were excluded after abstract screening. Of n = 149 full-text articles assessed for eligibility, n = 87 were included for quantitative synthesis, grouped according to suicide behavior outcome. Reports varied widely in methodology and outcomes. Results suggest high levels of risk classification accuracy (>90%) and Area Under the Curve (AUC) in the prediction of suicidal behaviors. We report key findings and central limitations in the use of AI/ML frameworks to guide additional research, which hold the potential to impact suicide on broad scale.

Suicide during Transition of Care: a Review of Targeted Interventions

The risk of suicide is significant during the transition of care; the highest in the first few weeks after discharge from a healthcare facility. This systematic review summarizes the evidence for interventions providing care during this high-risk period. In January 2019, PubMed and Scopus were systematically searched using the search terms: Suicide AND (Hospital OR Emergency department) AND Discharge. Articles relevant to interventions targeting suicidal behaviors during the transition of care were selected after the title and abstract screening followed by full-text screening. This review article included 40 articles; with a total patient population of 24,568. The interventions included telephone contacts, letters, green cards, postcards, structured visits, and community outreach programs. An improvement in the engagement of patients in outpatient services was observed but the evidence for suicidal behaviors was conflicting. The reviewed interventions were efficacious in linking patients to outpatient services, reducing feelings of social isolation and helping patients in navigating the available community resources. For patients with repetitive suicidal behaviors, psychosocial interventions such as dialectical behavioral therapy can be helpful. Patients should be followed by targeted interventions based on risk categorization of the patients by using evidence-based tools.

Caring E-mails for Military and Veteran Suicide Prevention: A Randomized Controlled Trial

OBJECTIVE

The purpose of this multisite study was to conduct a randomized controlled trial of an e-mail version of the caring letters (CL) suicide prevention intervention to determine whether the intervention is efficacious in preventing suicide behaviors among U.S. service members and veterans.

METHOD

Psychiatric inpatients (N = 1,318) were recruited from four military medical centers and two VA hospitals and randomized to receive either 13 caring e-mails over two years or usual care.

RESULTS

There were 10 deaths from any cause in the CL group (three suicides) and 14 in the usual care group (seven suicides) during the individual two-year follow-up intervals. There was no statistically significant difference in the rate of all-cause hospital readmission between the study groups (RR = 1.13; 95% CI = 0.94, 1.36). There were no differences observed between groups on self-reported psychiatric hospital readmissions, self-reported suicide attempts, or other measures associated with risk for suicide.

CONCLUSIONS

No firm conclusions about the efficacy of the intervention can be made because the study was inadequately powered. There were no adverse events associated with the intervention, and implementation of the procedures was feasible in the military and veteran hospital settings. These results provide important methodological considerations for caring contact trials in military populations.

Community-based aftercare following an emergency department presentation for attempted suicide or high risk for suicide: study protocol for a non-randomised controlled trial

BACKGROUND

Suicide is a major public health issue worldwide. Those who have made a recent suicide attempt are at high risk for dying by suicide in the future, particularly during the period immediately following departure from a hospital emergency department. As such the transition from hospital-based care to the community is an important area of focus in the attempt to reduce suicide rates. There is a need for evaluation studies to test the effectiveness of interventions directed to this stage (termed 'aftercare' interventions).

METHODS

A controlled non-randomised two group (intervention vs treatment-as-usual control) design, using an intention-to-treat model, will evaluate the effectiveness of a suicide prevention aftercare intervention providing follow-up after presentations to a hospital emergency department as a result of a suicide attempt or high risk for suicide. The intervention is a community-based service, utilising two meetings with a mental health clinician and follow-up contacts by peer workers via a combination of face-to-face and telephone for four weeks, with the option of extension to 12 weeks. Seventy-five participants of the intervention service will be recruited to the study and compared to 1265 treatment-as-usual controls. The primary hypotheses are that over 12 months, those who participate in the aftercare follow-up intervention are less likely than controls to present to a hospital emergency department for a repeat suicide attempt or because of high risk for suicide, will have fewer re-presentations during this period and will have lower all-cause mortality. As a secondary aim, the impact of the intervention on suicide risk factors for those who participate in the service will be evaluated using pre- and post-intervention repeated measures of depression, anxiety, stress, hopelessness, belongingness, burdensomeness, and psychological distress. Enrolments into the study commenced on 1 November 2017 and are anticipated to cease in November 2019.

DISCUSSION

The study aims to contribute to the understanding of effective interventions for individuals who have presented to a hospital emergency department as a result of a suicide attempt or at high risk for suicide and provide evidence in relation to interventions that incorporate peer-workers.

Veteran Preferences for the Caring Contacts Suicide Prevention Intervention

OBJECTIVE

The Caring Contacts intervention has been implemented with a variety of methodologies. The purpose of this study was to examine high-risk inpatient preferences for the Caring Contacts intervention.

METHOD

Veteran psychiatric inpatients (N = 154) completed an anonymous patient preferences survey to obtain feedback on Caring Contact methods such as message wording, preferred correspondent, frequency of contact, duration of the intervention, imagery, and mailing modality.

RESULTS

Eighty-five percent of veterans Agreed or Strongly Agreed that they would like to receive Caring Contacts from at least one of the correspondent options, with inpatient or outpatient mental health counselor, or primary care physician most preferred. Example messages based on prior studies were overwhelmingly rated as caring and helpful; 84% believed that Caring Contacts could help suicidal individuals. Letters or postcards sent through postal mail were preferred over e-mail or text messages. Participants most commonly thought Caring Contacts should be sent monthly for a period of a year.

CONCLUSIONS

The results of this study suggest that most high-risk veterans would perceive Caring Contacts as helpful and caring. The results provide several practical, helpful tips for programs seeking to establish a Caring Contacts program.

A Comparative Effectiveness Trial of Two Patient-Centered Interventions for Women with Unmet Social Needs: Personalized Support for Progress and Enhanced Screening and Referral

Background: Despite recent widespread acceptance that unmet social needs are critically relevant to health, limited guidance exists about how best to address them in the context of women's health care delivery. We aimed to evaluate two interventions: enhanced screening and referral (ESR), a screening intervention with facilitated referral and follow-up calls, and personalized support for progress (PSP), a community health worker intervention tailored to women's priorities. Materials and Methods: Women >18 years were screened for presence of elevated depressive symptoms in three women's health clinics serving primarily Medicaid-eligible patients. If eligible and interested, we enrolled and randomized women to ESR or PSP. Pre- and postintervention assessments were conducted. Primary outcomes were satisfaction, depression, and quality of life (QOL). Planned analyses of subgroup differences were also explored. Results: A total of 235 participants were randomized; 54% identified as African American, 19% as White, and 15% as Latina. Participant mean age was 30 years; 77% reported annual incomes below US $20,000/year; and 30% were pregnant at enrollment. Participants in both arms found the interventions satisfactory and improved for depression (p < 0.001). There were no differences between groups for the primary outcomes. Subgroups reporting greater improvement in QOL in PSP compared with ESR included participants who at baseline reported anxiety (p = 0.05), lack of access to depression treatment (p = 0.02), pain (p = 0.04), and intimate partner violence (p = 0.02). Conclusions: Clinics serving women with unmet social needs may benefit from offering PSP or ESR. Distinguishing how best to use these interventions in practice is the next step.

Effect of Augmenting Standard Care for Military Personnel With Brief Caring Text Messages for Suicide Prevention: A Randomized Clinical Trial

IMPORTANCE

Accessible and cost-effective interventions for suicidality are needed to address high rates of suicidal behavior among military service members. Caring Contacts are brief periodic messages that express unconditional care and concern and have been previously shown to prevent suicide deaths, attempts, ideation, and hospitalizations.

OBJECTIVE

To test the effectiveness of augmenting standard military health care with Caring Contacts delivered via text message to reduce suicidal thoughts and behaviors over 12 months.

DESIGN, SETTING, AND PARTICIPANTS

This randomized clinical trial was conducted at 3 military installations in the southern and western United States. Soldiers and Marines identified as being at risk of suicide were recruited between April 2013 and September 2016. The final follow-up was in September 2017.

INTERVENTIONS

Both groups received standard care, and the Caring Contacts group also received consisted of 11 text messages delivered on day 1, at week 1, at months 1, 2, 3, 4, 6, 8, 10, and 12, and on participants' birthdays.

MAIN OUTCOMES AND MEASURES

Primary outcomes were current suicidal ideation and suicide risk incidents (hospitalization or medical evacuation). Secondary outcomes were worst-point suicidal ideation, emergency department visits, and suicide attempts. Suicidal ideation was measured by the Scale for Suicide Ideation, suicide risk incidents, and emergency department visits by the Treatment History Interview; attempted suicide was measured by the Suicide Attempt Self-Injury Count.

RESULTS

Among 658 randomized participants (329 randomizely assigned to each group), data were analyzed for 657 individuals (mean [SD] age, 25.2 [6.1] years; 539 men [82.0%]). All participants reported suicidal ideation at baseline, and 291 (44.3%) had previously attempted suicide. Of the 657 participants, 461 (70.2%) were assessed at 12 months. Primary outcomes were nonsignificant. There was no significant effect on likelihood or severity of current suicidal ideation or likelihood of a suicide risk incident; there was also no effect on emergency department visits. However, participants who received Caring Contacts (172 of 216 participants [79.6%]) had lower odds than those receiving standard care alone (179 of 204 participants [87.7%]) of experiencing any suicidal ideation between baseline and follow-up (odds ratio, 0.56 [95% CI, 0.33-0.95]; P = .03) and fewer had attempted suicide since baseline (21 of 233 [9.0%] in the group receiving Caring Contacts vs 34 of 228 [14.9%] in the standard-care group; odds ratio, 0.52 [95% CI, 0.29-0.92]; P = .03).

CONCLUSIONS AND RELEVANCE

This trial provides inconsistent results on the effectiveness of caring text messages between primary and secondary outcomes, but this inexpensive and scalable intervention offers promise for preventing suicide attempts and ideation in military personnel. Additional research is needed.

Active contact and follow-up interventions to prevent repeat suicide attempts during high-risk periods among patients admitted to emergency departments for suicidal behavior: a systematic review and meta-analysis

BACKGROUND

There is evidence that several intervention types, including psychotherapy, reduce repeat suicide attempts. However, these interventions are less applicable to the heterogeneous patients admitted to emergency departments (EDs). The risk of a repeat suicide attempt is especially high in the first 6 months after the initial attempt. Therefore, it is particularly important to develop effective ED interventions to prevent repeat suicide attempts during this 6-month period.

METHODS

We systematically reviewed randomized controlled trials of ED-initiated interventions for suicidal patients admitted to EDs using the databases MEDLINE, PsychoINFO, CINAHL, and EMBASE up to January 2015 in accordance with an a priori published protocol (PROSPERO: CRD42013005463). Interventions were categorized into four types, including active contact and follow-up interventions (intensive care plus outreach, brief interventions and contact, letter/postcard, telephone, and composite of letter/postcard and telephone), and a meta-analysis was conducted to determine pooled relative risks (RRs) and 95% confidence intervals (CIs) of a repeat suicide attempt within 6 months.

RESULTS

Of the 28 selected trials, 14 were active contact and follow-up interventions. Two of these trials (n = 984) reported results at 6 months (pooled RR = 0.48; 95% CI: 0.31 to 0.76). There were not enough trials of other interventions to perform meta-analysis. Some trials included in the meta-analysis were judged as showing risk of bias.

CONCLUSION

Active contact and follow-up interventions are recommended for suicidal patients admitted to an ED to prevent repeat suicide attempts during the highest-risk period of 6 months.

Predictors of self-harm emergency department visits in adolescents: A statewide longitudinal study

OBJECTIVE

This study investigated patient- and area-level characteristics associated with adolescent emergency department (ED) patients' risk of subsequent ED visits for self-harm.

METHOD

Retrospective analysis of adolescent patients presenting to a California ED in 2010 (n = 480,706) was conducted using statewide, all-payer, individually linkable administrative data. We examined associations between multiple predictors of interest (patient sociodemographic factors, prior ED utilization, and residential mobility; and area-level characteristics) and odds of a self-harm ED visit in 2010. Patients with any self-harm in 2010 were followed up over several years to assess predictors of recurrent self-harm.

RESULTS

Self-harm patients (n = 5539) were significantly more likely than control patients (n = 16,617) to have prior histories of ED utilization, particularly for mental health problems, substance abuse, and injuries. Residential mobility also increased risk of self-harm, but racial/ethnic minority status and residence in a disadvantaged zipcode decreased risk. Five-year cumulative incidence of recurrent self-harm was 19.3%. Admission as an inpatient at index visit, Medicaid insurance, and prior ED utilization for psychiatric problems or injury all increased recurrent self-harm risk.

CONCLUSIONS

A range of patient- and area-level characteristics observable in ED settings are associated with risk for subsequent self-harm among adolescents, suggesting new targets for intervention in this clinical context.

Follow-up with Callers to the National Suicide Prevention Lifeline: Evaluation of Callers' Perceptions of Care

Continuity of care for suicidal individuals engaged with a variety of health and mental health care systems has become a national priority, and crisis hotlines are increasingly playing a part in the risk management and continuum of care for these individuals. The current study evaluated a national initiative to have crisis centers in the National Suicide Prevention Lifeline network provide follow-up care to suicidal callers. Data were obtained from 550 callers followed by 41 crisis counselors from 6 centers. Two main data sources provided the information for the current study: a self-report counselor questionnaire on the follow-up activities completed on each clinical follow-up call and a telephone interview with follow-up clients, providing data on their perceptions of the follow-up intervention's effectiveness. The majority of interviewed follow-up clients reported that the intervention stopped them from killing themselves (79.6%) and kept them safe (90.6%). Counselor activities, such as discussing distractors, social contacts to call for help, and reasons for dying, and individual factors, such as baseline suicide risk, were associated with callers' perceptions of the impact of the intervention on their suicide risk. Our findings provide evidence that follow-up calls to suicidal individuals can reduce the perceived risk of future suicidal behavior.

Modeling the Cost-Effectiveness of Interventions to Reduce Suicide Risk Among Hospital Emergency Department Patients

OBJECTIVE

This study estimated the expected cost-effectiveness and population impact of outpatient interventions to reduce suicide risk among patients presenting to general hospital emergency departments (EDs), compared with usual care. Several such interventions have been found efficacious, but none is yet widespread, and the cost-effectiveness of population-based implementation is unknown.

METHODS

Modeled cost-effectiveness analysis compared three ED-initiated suicide prevention interventions previously found to be efficacious-follow-up via postcards or caring letters, follow-up via telephone outreach, and suicide-focused cognitive-behavioral therapy (CBT)-with usual care. Primary outcomes were treatment costs, suicides, and life-years saved, evaluated over the year after the index ED visit.

RESULTS

Compared with usual care, adding postcards improved outcomes and reduced costs. Adding telephone outreach and suicide-focused CBT, respectively, improved outcomes at a mean incremental cost of $4,300 and $18,800 per life-year saved, respectively. Monte Carlo simulation (1,000 repetitions) revealed the chance of incremental cost-effectiveness to be a certainty for all three interventions, assuming societal willingness to pay ≥$50,000 per life-year. These main findings were robust to various sensitivity analyses, including conservative assumptions about effect size and incremental costs. Population impact was limited by low sensitivity of detecting ED patients' suicide risk, and health care delivery inefficiencies.

CONCLUSIONS

The highly favorable cost-effectiveness found for each outpatient intervention provides a strong basis for widespread implementation of any or all of the interventions. The estimated population benefits of doing so would be enhanced by increasing the sensitivity of suicide risk detection among individuals presenting to general hospital EDs.

The Emergency Department: Challenges and Opportunities for Suicide Prevention

Emergency departments (EDs) can offer life-saving suicide prevention care. This article focuses on the ED and emergency services as service delivery sites for suicide prevention. Characteristics of EDs, models of emergency care, ED screening and brief intervention models, and practice guidelines and parameters are reviewed. A care process model for youths at risk for suicide and self-harm is presented, with guidance for clinicians based on the scientific evidence. Strengthening emergency infrastructure and integrating effective suicide prevention strategies derived from scientific research are critical for advancing suicide prevention objectives.

Taking care of suicidal patients with new technologies and reaching-out means in the post-discharge period

Suicide is a global public health problem with over one million people dying by suicide each year worldwide. Research efforts have focused on developing and testing novel suicide prevention strategies employing recent technological advances. In order to provide a review regarding the role of new technologies (e.g., postcards/letters, text messages, crisis cards, telephone contacts, online interventions) in suicide prevention, we searched PubMed, ScienceDirect, ResearchGate, and Crisis to identify all papers in English from 1977 to 2016. Our results indicated that brief contact interventions show promise in reducing the number of episodes of repeated self-harm and/or suicide attempts following discharge from the Emergency Department or psychiatric units. Innovative methods of contact (e.g., text messages) are easily implemented by clinicians and received by patients in the period of post discharge and have been shown to be beneficial. However, more research employing randomized clinical trials investigating the potential benefits of these novel suicide prevention methods is warranted. Future researchers should continue improving and testing new technologies in the prevention of suicide.

A Novel Therapy for People Who Attempt Suicide and Why We Need New Models of Suicide

This paper presents a model of suicidal behaviour based on suicide as a goal-directed action, and its implications. An action theoretical model has guided the authors in the development of a brief therapy for individuals who attempt suicide (ASSIP—Attempted Suicide Short Intervention Program). Key elements are an early therapeutic alliance, narrative interviewing, psychoeducation, a joint case conceptualization, safety planning, and regular letters over 24 months. In a randomized controlled trial, ASSIP was highly effective in reducing the risk of suicide reattempts. The therapeutic elements in this treatment are described and possible implications for future directions in clinical suicide prevention discussed.

Differences in the Effectiveness of Psychosocial Interventions for Suicidal Ideation and Behaviour in Women and Men: A Systematic Review of Randomised Controlled Trials

The objective of this study was to explore outcomes of preventive programs and psychosocial treatments for suicidal ideation and behaviour in gender sub-groups in mixed gender studies and in studies limited to one gender. The method used was a systematic review of randomized controlled trials (RCTs) which included women or men only, or reported and/or examined outcomes of psychosocial interventions in mixed gender samples. A total of 27 (18%) of RCTs reported or examined differences in intervention outcomes. Of the mixed gender RCTs, 5 (33%) reported greater effectiveness for females than males. The review identified promising interventions in female-only samples. None of the trials reported greater effectiveness of the intervention in men. The majority of reviewed studies looking at treatment outcomes in gender sub-groups showed no differences between women and men or indicated that some psychosocial interventions are effective for women. There is a need for studies which look at gender effects and development of interventions more effective and appealing for men at risk of suicide.

Postcards in Persia: A Twelve to Twenty-four Month Follow-up of a Randomized Controlled Trial for Hospital-Treated Deliberate Self-Poisoning

This study reports the outcomes, during follow-up, of a low-cost postcard intervention in a Randomized Control Trial of hospital-treated self-poisoning (n = 2300). The intervention was 9 postcards over 12 months (plus usual treatment) versus usual treatment. Three binary endpoints at 12-24 months (n = 2001) were: any suicidal ideation, suicide attempt, or self-cutting. There was a significant reduction in any suicidal ideation (RRR 0.20 CI 95% 0.13-0.27), (NNT 8, 6-13), and any suicide attempt (RRR 0.31, 0.06-0.50), (NNT 35, 19-195), in this non-western population. However, there was no effect on self-cutting (RRR -0.01, -1.05-0.51). Sustained, brief contact by mail may reduce some forms of suicidal behavior in self-poisoning patients during the post intervention phase.

Suicide Ideation Is Related to Therapeutic Alliance in a Brief Therapy for Attempted Suicide

The objective of this study was to investigate the role of therapeutic alliance on suicide ideation as outcome measure in a brief therapy for patients who attempted suicide. Sixty patients received the 3-session therapy supplemented by follow-up contact through regular letters. Therapeutic alliance was measured with the Helping Alliance Questionnaire (HAQ). Outcome at 6 and 12 months was measured with the Beck Scale for Suicide Ideation (BSS). Therapeutic alliance increased from session 1 to session 3. Higher alliance measures correlated with lower suicidal ideation at 12 months follow-up. A history of previous attempts and depression had a negative affect on therapeutic alliance. The results suggest that in the treatment of suicidal patients therapeutic alliance may be a moderating factor for reducing suicide ideation.

Royal Australian and New Zealand College of Psychiatrists clinical practice guideline for the management of deliberate self-harm

OBJECTIVE

To provide guidance for the organisation and delivery of clinical services and the clinical management of patients who deliberately self-harm, based on scientific evidence supplemented by expert clinical consensus and expressed as recommendations.

METHOD

Articles and information were sourced from search engines including PubMed, EMBASE, MEDLINE and PsycINFO for several systematic reviews, which were supplemented by literature known to the deliberate self-harm working group, and from published systematic reviews and guidelines for deliberate self-harm. Information was reviewed by members of the deliberate self-harm working group, and findings were then formulated into consensus-based recommendations and clinical guidance. The guidelines were subjected to successive consultation and external review involving expert and clinical advisors, the public, key stakeholders, professional bodies and specialist groups with interest and expertise in deliberate self-harm.

RESULTS

The Royal Australian and New Zealand College of Psychiatrists clinical practice guidelines for deliberate self-harm provide up-to-date guidance and advice regarding the management of deliberate self-harm patients, which is informed by evidence and clinical experience. The clinical practice guidelines for deliberate self-harm is intended for clinical use and service development by psychiatrists, psychologists, physicians and others with an interest in mental health care.

CONCLUSION

The clinical practice guidelines for deliberate self-harm address self-harm within specific population sub-groups and provide up-to-date recommendations and guidance within an evidence-based framework, supplemented by expert clinical consensus.

Effective psychological and psychosocial approaches to reduce repetition of self-harm: a systematic review, meta-analysis and meta-regression

OBJECTIVE

To examine the efficacy of psychological and psychosocial interventions for reductions in repeated self-harm.

DESIGN

We conducted a systematic review, meta-analysis and meta-regression to examine the efficacy of psychological and psychosocial interventions to reduce repeat self-harm in adults. We included a sensitivity analysis of studies with a low risk of bias for the meta-analysis. For the meta-regression, we examined whether the type, intensity (primary analyses) and other components of intervention or methodology (secondary analyses) modified the overall intervention effect.

DATA SOURCES

A comprehensive search of MEDLINE, PsycInfo and EMBASE (from 1999 to June 2016) was performed.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Randomised controlled trials of psychological and psychosocial interventions for adult self-harm patients.

RESULTS

Forty-five trials were included with data available from 36 (7354 participants) for the primary analysis. Meta-analysis showed a significant benefit of all psychological and psychosocial interventions combined (risk ratio 0.84; 95% CI 0.74 to 0.96; number needed to treat=33); however, sensitivity analyses showed that this benefit was non-significant when restricted to a limited number of high-quality studies. Meta-regression showed that the type of intervention did not modify the treatment effects.

CONCLUSIONS

Consideration of a psychological or psychosocial intervention over and above treatment as usual is worthwhile; with the public health benefits of ensuring that this practice is widely adopted potentially worth the investment. However, the specific type and nature of the intervention that should be delivered is not yet clear. Cognitive-behavioural therapy or interventions with an interpersonal focus and targeted on the precipitants to self-harm may be the best candidates on the current evidence. Further research is required.

Follow-up of young patients after acute poisoning by substances of abuse: a comparative cohort study at an emergency outpatient clinic

BACKGROUND

Young patients with acute poisoning by substances of abuse have increased mortality rates in the long term. In Oslo, Norway, most of these patients are treated at the Oslo Accident and Emergency Outpatient Clinic. The majority were discharged without follow-up. In 2010, the clinic implemented an intervention program for patients under the age of 23 presenting with acute poisoning by substances of abuse. The intervention was a brief motivational interview with a social worker before discharge, followed by a telephone consultation. Patients in need of further follow-up were identified and referred. Our objective was to study short-term effects of the intervention program on referrals to follow-up and repetition rates of acute poisoning.

METHODS

Comparative cohorts were derived from studies of acute poisoning at the Oslo Accident and Emergency Outpatient Clinic in 2003, 2008 and 2012. Two age groups of patients presenting with acute poisoning by substances of abuse were included: 16-22 years and 23-27 years. Patients in the pre-intervention cohorts of 2003 and 2008 were compared with patients of the same age in the post-intervention cohort of 2012. Repetition rates were estimated using survival analysis. In total, 1323 patients were included; 422 in the younger pre-intervention group, 366 in the younger post-intervention group, 288 in the older pre-intervention group, and 247 in the older post-intervention group. Overall, the major toxic agents were ethanol 823/1323 (62 %) and opioids 215/1323 (16 %). 719/1323 (54 %) patients were male.

RESULTS

In the younger groups referrals to follow-up increased from 86/317 (27 %) to 156/366 (43 %) (p < 0.001) after the implementation of the program. Among the older patients, who were not included in the program, there was no significant change in referrals. There was no change in the repetition rate of acute poisoning in either age group. The program established contact with 225/366 (61 %) of the eligible patients.

CONCLUSION

More patients were referred to follow-up after the intervention. We expect this to have a beneficial effect on their substance use and reduce excess morbidity and mortality in the long term. There was no change in the repetition rate of poisoning.

Psychosocial interventions following self-harm in adults: a systematic review and meta-analysis

BACKGROUND

Self-harm (intentional acts of non-fatal self-poisoning or self-injury) is common, particularly in young adults aged 15-35 years, often repeated, and strongly associated with suicide. Effective aftercare of individuals who self-harm is therefore important. We have undertaken a Cochrane systematic review and meta-analysis of the effectiveness of psychosocial interventions for self-harm in adults.

METHODS

We searched five electronic databases (CCDANCTR-Studies and References, CENTRAL, MEDLINE, Embase, and PsycINFO) between Jan 1, 1998, and April 29, 2015, for randomised controlled trials of psychosocial interventions for adults after a recent (within 6 months) episode of self-harm. Most interventions were assessed in single trials. We report results for interventions for which at least three randomised controlled trials comparing interventions with treatment as usual have been published and hence might contribute to clinical guidance. The primary outcome was repetition of self-harm at the conclusion of treatment and at 6, 12, and 24 months' follow-up analysed, when available, with the intention-to-treat method; if this was not possible, we analysed with all available case data.

FINDINGS

We identified 29 non-overlapping randomised controlled trials with three independent trials of the same intervention. Cognitive-behavioural-based psychotherapy (CBT; comprising cognitive-behavioural and problem-solving therapy) was associated with fewer participants repeating self-harm at 6 months' (odds ratio 0·54, 95% CI 0·34-0·85; 12 trials; n=1317) and at 12 months' follow-up (0·80, 0·65-0·98; ten trials; n=2232). There were also significant improvements in the secondary outcomes of depression, hopelessness, suicidal ideation, and problem solving. Patients receiving dialectical behaviour therapy (in three trials) were not less likely to repeat self-harm compared with those provided with treatment as usual at 6 months (odds ratio [OR] 0·59, 95% CI 0·16-2·15; n=267, three trials) or at 12 months (0·36, 0·05-2·47; n=172, two trials). However, the secondary endpoint of frequency of self-harm was associated with a significant reduction with use of dialectical behaviour therapy (mean difference -18·82, 95% CI -36·68 to -0·95). Four trials each of case management (OR 0·78, 95% CI 0·47-1·30; n=1608) and sending regular postcards (OR 0·87, 95% CI 0·62-1·23; n=3277) did not reduce repetition of self-harm.

INTERPRETATION

CBT seems to be effective in patients after self-harm. Dialectical behaviour therapy did not reduce the proportion of patients repeating self-harm but did reduce the frequency of self-harm. However, aside from CBT, there were few trials of other promising interventions, precluding firm conclusions as to their effectiveness.

A Pilot Study on the Efficacy of Volunteer Mentorship for Young Adults With Self-Harm Behaviors Using a Quasi-Experimental Design

BACKGROUND

Studies have shown that postdischarge care for self-harm patients is effective in reducing repeated suicidal behaviors. Little is known about whether volunteer support can help reduce self-harm repetition and improve psychosocial well-being.

AIM

This study investigated the efficacy of volunteer support in preventing repetition of self-harm.

METHOD

This study used a quasi-experimental design by assigning self-harm patients admitted to the emergency departments to an intervention group with volunteer support and treatment as usual (TAU) for 9 months and to a control group of TAU. Outcome measures include repetition of self-harm, suicidal ideation, hopelessness, and level of depressive and anxiety symptoms.

RESULTS

A total of 74 cases were recruited (38 participants; 36 controls). There were no significant differences in age, gender, and clinical condition between the two groups at the baseline. The intervention group showed significant improvements in hopelessness and depressive symptoms. However, the number of cases of suicide ideation and of repetition of self-harm episodes was similar for both groups at the postintervention period.

CONCLUSION

Postdischarge care provided by volunteers showed significant improvement in hopelessness and depression. Volunteers have been commonly involved in suicide prevention services. Further research using rigorous methods is recommended for improving service quality in the long term.

Mechanisms of brief contact interventions in clinical populations: a systematic review

BACKGROUND

Brief Contact Interventions (BCIs) have been of increasing interest to suicide prevention clinicians, researchers and policy makers. However, there has been no systematic assessment into the mechanisms underpinning BCIs. The aim of the current paper is to provide a systematic review of the proposed mechanisms underpinning BCIs across trial studies.

METHOD

A systematic review was conducted of trials using BCIs (post-discharge telephone contacts; emergency or crisis cards; and postcard or letter contacts) for suicide or self-harm. Following PRISMA guidelines, we searched CENTRAL, MEDLINE, EMBASE, and the reference lists of all past reviews in the area. Secondary searches of reference lists were undertaken.

RESULTS

Sixteen papers provided a description of possible mechanisms which we grouped into three main areas: social support; suicide prevention literacy, and; learning alternative coping behaviours. After assessment of the studies and considering the plausibility of mechanisms, we suggest social support and improved suicide prevention literacy are the most likely mechanisms underpinning BCIs.

CONCLUSION

Researchers need to better articulate and measure the mechanisms they believe underpin BCIs in trial studies. Understanding more about the mechanisms of BCIs' will inform the development of future interventions for self-harm and suicide.

Direct versus indirect psychosocial and behavioural interventions to prevent suicide and suicide attempts: a systematic review and meta-analysis

BACKGROUND

Psychosocial and behavioural interventions that address suicidal thoughts and behaviour during treatment (direct interventions) might be more effective in preventing suicide and suicide attempts than indirect interventions that address symptoms associated with suicidal behaviour only (eg, hopelessness, depression, anxiety, quality of life). To test this hypothesis, we did a systematic review and meta-analysis of psychosocial and behavioural interventions aimed at preventing suicide and suicide attempts.

METHODS

For this systematic review and meta-analysis, we searched MEDLINE and PsycINFO from inception to Dec 25, 2015, for randomised controlled trials that reported suicides or suicide attempts as an outcome, irrespective of participants' diagnoses or the publication language. We excluded studies with pharmacological or device-based interventions, those that targeted communities or clinicians, primary prevention trials, and trials that reported events of non-suicidal self-injury as suicide attempts. Trials that had no suicides or suicide attempts in both groups were also excluded. Data were extracted by one investigator and independently verified by a second investigator. We used random-effects models of the odds ratio (OR) based on a pooled measure of suicides and the number of individuals who attempted suicide, immediately post-treatment and at longer-term follow-up.

FINDINGS

Of 2024 unique abstracts screened, 53 articles met eligibility criteria and reported on 44 studies; 31 studies provided post-treatment data with 6658 intervention group participants and 6711 control group participants at baseline, and 29 studies provided follow-up data. The post-treatment difference between direct interventions and indirect interventions did not reach statistical significance at the 0·05 level (OR 0·62 [95% CI 0·45-0·87] vs 0·93 [0·77-1·12], p=0·06) and represented a large effect size (Cohen's d=0·77). At longer-term follow-up, the difference was not significant (OR 0·65 [0·46-0·91] vs 0·82 [0·70-0·96], p=0·25) but still represented a medium effect size (Cohen's d=0·47). These effect sizes emphasise the clinical importance of direct interventions. Post-hoc subgroup and sensitivity analyses showed that our results are robust and unlikely to be notably affected by between-study heterogeneity or publication bias.

INTERPRETATION

Psychosocial and behavioural interventions that directly address suicidal thoughts and behaviour are effective immediately post-treatment and long term, whereas treatments indirectly addressing these components are only effective long term. Moreover, although the differences shown between direct and indirect strategies were non-significant, the difference in favour of direct interventions represented a large post-treatment improvement and medium improvement at longer-term follow-up. On the basis of these findings, clinicians working with patients at risk of suicide should address suicidal thoughts and behaviours with the patient directly. Although direct interventions are effective, they are not sufficient, and additional efforts are needed to further reduce death by suicide and suicide attempts. Continued patient contact might be necessary to retain long-term effectiveness.

Wise Additions Bridge the Gap between Social Psychology and Clinical Practice: Cognitive-Behavioral Therapy as an Exemplar

Progress in clinical science, theory, and practice requires the integration of advances from multiple fields of psychology, but much integration remains to be done. The current article seeks to address the specific gap that exists between basic social psychological theories and the implementation of related therapeutic techniques. We propose several "wise additions," based upon the principles outlined by Walton (2014), intended to bridge current social psychological research with clinical psychological therapeutic practice using cognitive behavioral therapy as an example. We consider how recent advances in social psychological theories can inform the development and implementation of wise additions in clinical case conceptualization and interventions. We specifically focus on self and identity, self-affirmation, transference, social identity, and embodied cognition, five dominant areas of interest in the field that have clear clinical applications.

Psychosocial interventions for self-harm in adults

BACKGROUND

Self-harm (SH; intentional self-poisoning or self-injury) is common, often repeated, and associated with suicide. This is an update of a broader Cochrane review first published in 1998, previously updated in 1999, and now split into three separate reviews. This review focuses on psychosocial interventions in adults who engage in self-harm.

OBJECTIVES

To assess the effects of specific psychosocial treatments versus treatment as usual, enhanced usual care or other forms of psychological therapy, in adults following SH.

SEARCH METHODS

The Cochrane Depression, Anxiety and Neurosis Group (CCDAN) trials coordinator searched the CCDAN Clinical Trials Register (to 29 April 2015). This register includes relevant randomised controlled trials (RCTs) from: the Cochrane Library (all years), MEDLINE (1950 to date), EMBASE (1974 to date), and PsycINFO (1967 to date).

SELECTION CRITERIA

We included RCTs comparing psychosocial treatments with treatment as usual (TAU), enhanced usual care (EUC) or alternative treatments in adults with a recent (within six months) episode of SH resulting in presentation to clinical services.

DATA COLLECTION AND ANALYSIS

We used Cochrane's standard methodological procedures.

MAIN RESULTS

We included 55 trials, with a total of 17,699 participants. Eighteen trials investigated cognitive-behavioural-based psychotherapy (CBT-based psychotherapy; comprising cognitive-behavioural, problem-solving therapy or both). Nine investigated interventions for multiple repetition of SH/probable personality disorder, comprising emotion-regulation group-based psychotherapy, mentalisation, and dialectical behaviour therapy (DBT). Four investigated case management, and 11 examined remote contact interventions (postcards, emergency cards, telephone contact). Most other interventions were evaluated in only single small trials of moderate to very low quality.There was a significant treatment effect for CBT-based psychotherapy compared to TAU at final follow-up in terms of fewer participants repeating SH (odds ratio (OR) 0.70, 95% confidence interval (CI) 0.55 to 0.88; number of studies k = 17; N = 2665; GRADE: low quality evidence), but with no reduction in frequency of SH (mean difference (MD) -0.21, 95% CI -0.68 to 0.26; k = 6; N = 594; GRADE: low quality).For interventions typically delivered to individuals with a history of multiple episodes of SH/probable personality disorder, group-based emotion-regulation psychotherapy and mentalisation were associated with significantly reduced repetition when compared to TAU: group-based emotion-regulation psychotherapy (OR 0.34, 95% CI 0.13 to 0.88; k = 2; N = 83; GRADE: low quality), mentalisation (OR 0.35, 95% CI 0.17 to 0.73; k = 1; N = 134; GRADE: moderate quality). Compared with TAU, dialectical behaviour therapy (DBT) showed a significant reduction in frequency of SH at final follow-up (MD -18.82, 95% CI -36.68 to -0.95; k = 3; N = 292; GRADE: low quality) but not in the proportion of individuals repeating SH (OR 0.57, 95% CI 0.21 to 1.59, k = 3; N = 247; GRADE: low quality). Compared with an alternative form of psychological therapy, DBT-oriented therapy was also associated with a significant treatment effect for repetition of SH at final follow-up (OR 0.05, 95% CI 0.00 to 0.49; k = 1; N = 24; GRADE: low quality). However, neither DBT vs 'treatment by expert' (OR 1.18, 95% CI 0.35 to 3.95; k = 1; N = 97; GRADE: very low quality) nor prolonged exposure DBT vs standard exposure DBT (OR 0.67, 95% CI 0.08 to 5.68; k = 1; N =18; GRADE: low quality) were associated with a significant reduction in repetition of SH.Case management was not associated with a significant reduction in repetition of SH at post intervention compared to either TAU or enhanced usual care (OR 0.78, 95% CI 0.47 to 1.30; k = 4; N = 1608; GRADE: moderate quality). Continuity of care by the same therapist vs a different therapist was also not associated with a significant treatment effect for repetition (OR 0.28, 95% CI 0.07 to 1.10; k = 1; N = 136; GRADE: very low quality). None of the following remote contact interventions were associated with fewer participants repeating SH compared with TAU: adherence enhancement (OR 0.57, 95% CI 0.32 to 1.02; k = 1; N = 391; GRADE: low quality), mixed multimodal interventions (comprising psychological therapy and remote contact-based interventions) (OR 0.98, 95% CI 0.68 to 1.43; k = 1 study; N = 684; GRADE: low quality), including a culturally adapted form of this intervention (OR 0.83, 95% CI 0.44 to 1.55; k = 1; N = 167; GRADE: low quality), postcards (OR 0.87, 95% CI 0.62 to 1.23; k = 4; N = 3277; GRADE: very low quality), emergency cards (OR 0.82, 95% CI 0.31 to 2.14; k = 2; N = 1039; GRADE: low quality), general practitioner's letter (OR 1.15, 95% CI 0.93 to 1.44; k = 1; N = 1932; GRADE: moderate quality), telephone contact (OR 0.74, 95% CI 0.42 to 1.32; k = 3; N = 840; GRADE: very low quality), and mobile telephone-based psychological therapy (OR not estimable due to zero cell counts; GRADE: low quality).None of the following mixed interventions were associated with reduced repetition of SH compared to either alternative forms of psychological therapy: interpersonal problem-solving skills training, behaviour therapy, home-based problem-solving therapy, long-term psychotherapy; or to TAU: provision of information and support, treatment for alcohol misuse, intensive inpatient and community treatment, general hospital admission, or intensive outpatient treatment.We had only limited evidence on whether the intervention had different effects in men and women. Data on adverse effects, other than planned outcomes relating to suicidal behaviour, were not reported.

AUTHORS' CONCLUSIONS

CBT-based psychological therapy can result in fewer individuals repeating SH; however, the quality of this evidence, assessed using GRADE criteria, ranged between moderate and low. Dialectical behaviour therapy for people with multiple episodes of SH/probable personality disorder may lead to a reduction in frequency of SH, but this finding is based on low quality evidence. Case management and remote contact interventions did not appear to have any benefits in terms of reducing repetition of SH. Other therapeutic approaches were mostly evaluated in single trials of moderate to very low quality such that the evidence relating to these interventions is inconclusive.

A Novel Brief Therapy for Patients Who Attempt Suicide: A 24-months Follow-Up Randomized Controlled Study of the Attempted Suicide Short Intervention Program (ASSIP)

BACKGROUND

Attempted suicide is the main risk factor for suicide and repeated suicide attempts. However, the evidence for follow-up treatments reducing suicidal behavior in these patients is limited. The objective of the present study was to evaluate the efficacy of the Attempted Suicide Short Intervention Program (ASSIP) in reducing suicidal behavior. ASSIP is a novel brief therapy based on a patient-centered model of suicidal behavior, with an emphasis on early therapeutic alliance.

METHODS AND FINDINGS

Patients who had recently attempted suicide were randomly allocated to treatment as usual (n = 60) or treatment as usual plus ASSIP (n = 60). ASSIP participants received three therapy sessions followed by regular contact through personalized letters over 24 months. Participants considered to be at high risk of suicide were included, 63% were diagnosed with an affective disorder, and 50% had a history of prior suicide attempts. Clinical exclusion criteria were habitual self-harm, serious cognitive impairment, and psychotic disorder. Study participants completed a set of psychosocial and clinical questionnaires every 6 months over a 24-month follow-up period. The study represents a real-world clinical setting at an outpatient clinic of a university hospital of psychiatry. The primary outcome measure was repeat suicide attempts during the 24-month follow-up period. Secondary outcome measures were suicidal ideation, depression, and health-care utilization. Furthermore, effects of prior suicide attempts, depression at baseline, diagnosis, and therapeutic alliance on outcome were investigated. During the 24-month follow-up period, five repeat suicide attempts were recorded in the ASSIP group and 41 attempts in the control group. The rates of participants reattempting suicide at least once were 8.3% (n = 5) and 26.7% (n = 16). ASSIP was associated with an approximately 80% reduced risk of participants making at least one repeat suicide attempt (Wald χ21 = 13.1, 95% CI 12.4-13.7, p < 0.001). ASSIP participants spent 72% fewer days in the hospital during follow-up (ASSIP: 29 d; control group: 105 d; W = 94.5, p = 0.038). Higher scores of patient-rated therapeutic alliance in the ASSIP group were associated with a lower rate of repeat suicide attempts. Prior suicide attempts, depression, and a diagnosis of personality disorder at baseline did not significantly affect outcome. Participants with a diagnosis of borderline personality disorder (n = 20) had more previous suicide attempts and a higher number of reattempts. Key study limitations were missing data and dropout rates. Although both were generally low, they increased during follow-up. At 24 months, the group difference in dropout rate was significant: ASSIP, 7% (n = 4); control, 22% (n = 13). A further limitation is that we do not have detailed information of the co-active follow-up treatment apart from participant self-reports every 6 months on the setting and the duration of the co-active treatment.

CONCLUSIONS

ASSIP, a manual-based brief therapy for patients who have recently attempted suicide, administered in addition to the usual clinical treatment, was efficacious in reducing suicidal behavior in a real-world clinical setting. ASSIP fulfills the need for an easy-to-administer low-cost intervention. Large pragmatic trials will be needed to conclusively establish the efficacy of ASSIP and replicate our findings in other clinical settings.

Effect of Systematic Follow-Up by General Practitioners after Deliberate Self-Poisoning: A Randomised Controlled Trial

Objective

To assess whether systematic follow-up by general practitioners (GPs) of cases of deliberate self-poisoning (DSP) by their patients decreases psychiatric symptoms and suicidal behaviour compared with current practice.

Design

Randomised clinical trial with two parallel groups.

Setting

General practices in Oslo and the eastern part of Akershus County.

Participants

Patients aged 18–75 years admitted to hospital for DSP. We excluded patients diagnosed with psychoses, without a known GP, those not able to complete a questionnaire, and patients admitted to psychiatric in-patient care or other institutions where their GP could not follow them immediately after discharge.

Intervention

The GPs received a written guideline, contacted the patients and scheduled a consultation within one week after discharge, and then provided regular consultations for six months. We randomised the patients to either intervention (n = 78) or treatment as usual (n = 98).

Main Outcome Measures

Primary outcome measure was the Beck Scale for Suicide Ideation (SSI). Secondary outcomes were Beck Depression Inventory (BDI) and Beck Hopelessness Scale (BHS), self-reported further self-harm and treatment for DSP in a general hospital or an emergency medical agency (EMA). We assessed patients on entry to the trial and at three and six months. We collected data from interviews, self-report questionnaires, and hospital and EMA medical records.

Results

There were no significant differences between the groups in SSI, BDI, or BHS mean scores or change from baseline to three or six months. During follow-up, self-reported DSP was 39.5% in the intervention group vs. 15.8% in controls (P = 0.009). Readmissions to general hospitals were similar (13% in both groups (P = 0.963), while DSP episodes treated at EMAs were 17% in the intervention group and 7% in the control group (P = 0.103).

Conclusion

Structured follow-up by GPs after an episode of DSP had no significant effect on suicide ideation, depression or hopelessness. There was no significant difference in repeated episodes of DSP in hospitals or EMAs. However, the total number of incidents of deliberate self-harm reported by the patients was significantly higher in the intervention group.
