RESUMEN

Decedents with no known mental disorder comprise 5-40% of suicides, suggesting that suicide ideation (SI) and behavior may occur in the psychiatrically healthy with important implications for suicide risk screening. Healthy Volunteers (HV) and patients with Major Depressive Disorder (MDD) provided 7 days of Ecological Momentary Assessment (EMA) data about SI and stressors. Longitudinal mixed effects logistic regression models compared HV and patient SI and stressors. Mixed effects linear regression models compared HVs' and patients' SI score change from the previous epoch's SI score when each stressor occurred. HVs (n = 42) reported less frequent (p < 0.001) and less intense SI (p < 0.003) than patients (n = 80), yet did endorse SI and/or SI-related items in 44% of EMA epochs, endorsing SI items in 25% of epochs with non-zero SI scores. For 7 of 8 stressors, patients reported stressors more often than HVs (all p < 0.001) responding to them with increased SI (0.0001 < p < 0.0472). HVs were relatively resilient to stressors, reporting SI increases only in response to neglect (p < 0.0147). Although SI and SAs are documented among psychiatrically healthy individuals, scientific attention to these observations has been scant. Real-time SI measurement showed that HVs' SI was less pronounced than MDD patients', but was endorsed, nonetheless. Patients were more likely to report stressors than HVs, perhaps due to greater sensitivity to the environment, and reported SI in response to stressors, which was less common in HVs. Both MDD patients and HVs most often manifested passive SI (viz, "decreased wish to live"). However, passive SI (viz, "desire for death"), may predict suicide, even absent SI per se (thinking about killing yourself). This study validates the utility of real-time SI assessment, showing that HVs endorse SI items in 11% of epochs, which implies that suicide risk screening focused on those with mental disorders may be too narrow an approach.

RESUMEN

AIMS: Despite the public health impact of violence among young adults with psychosis, behavioural interventions to reduce the risk of engaging in violence remain rare. For young adults with early psychosis, cognitive behavioural therapy (CBT)-based psychotherapy has efficacy in reducing impairment and improving functioning. However, no CBT-based intervention to reduce violence has been formally adapted for young adults with early psychosis. This protocol outlines the first clinical trial of a behavioural intervention to reduce violence for young adults with early psychosis. This study is set in an early intervention services (EIS) setting and seeks to adapt and pilot Psychological Intervention for Complex PTSD and Schizophrenia-Spectrum Disorder (PICASSO), a CBT-based intervention, through an iterative process utilizing mixed-methods assessments. METHODS: All research will occur at OnTrackNY, the largest EIS program in the United States. This study will consist of an open pilot trial, with four EIS clinicians delivering the intervention to one to two EIS participants per round. In this mixed-methods study, both quantitative measures (acceptability, feasibility and hypothesized mediators of target outcome collected on a weekly basis) and qualitative interviews (with EIS clinicians at weeks 4, 8 and 12) will be conducted. Transcripts will be analyzed using thematic content analysis. Two to three rounds of iterative modifications are anticipated (n = 10-16 EIS participants total). RESULTS: Recruitment began in February 2024 and is expected to continue over a 9-12-month period. CONCLUSIONS: Because violent behaviour causes interpersonal disruptions such as incarceration and increased caregiver burden, an innovative intervention to reduce violence risk could have broader health impact for this vulnerable population. Adapting the PICASSO intervention to the EIS setting will optimize its acceptability and feasibility by the intended target population.

RESUMEN

BACKGROUND: The Safety Planning Intervention with follow-up services (SPI+) is a promising suicide prevention intervention, yet many Emergency Departments (EDs) lack the resources for adequate implementation. Comprehensive strategies addressing structural and organizational barriers are needed to optimize SPI+ implementation and scale-up. This protocol describes a test of one strategy in which ED staff connect at-risk patients to expert clinicians from a Suicide Prevention Consultation Center (SPCC) via telehealth. METHOD: This stepped wedge, cluster-randomized trial compares the effectiveness, implementation, cost, and cost offsets of SPI+ delivered by SPCC clinicians versus ED-based clinicians (enhanced usual care; EUC). Eight EDs will start with EUC and cross over to the SPCC phase. Blocks of two EDs will be randomly assigned to start dates 3 months apart. Approximately 13,320 adults discharged following a suicide-related ED visit will be included; EUC and SPCC samples will comprise patients from before and after SPCC crossover, respectively. Effectiveness data sources are electronic health records, administrative claims, and the National Death Index. Primary effectiveness outcomes are presence of suicidal behavior and number/type of mental healthcare visits and secondary outcomes include number/type of suicide-related acute services 6-months post-discharge. We will use the same data sources to assess cost offsets to gauge SPCC scalability and sustainability. We will examine preliminary implementation outcomes (reach, adoption, fidelity, acceptability, and feasibility) through patient, clinician, and health-system leader interviews and surveys. CONCLUSION: If the SPCC demonstrates clinical effectiveness and health system cost reduction, it may be a scalable model for evidence-based suicide prevention in the ED.

RESUMEN

INTRODUCTION: Understanding the specific strategies individuals use to cope with their suicidal thoughts may have implications for suicide prevention. This study developed a classification system of coping strategies and applied this system to individual coping behaviors documented in a safety planning intervention smartphone application called Beyond Now. METHOD: 725 Beyond Now safety planning app users, aged 16 to over 55 years, entered coping strategies that were used to develop a classification system through content analysis. Entries were either user generated or selected from a list of suggested coping strategies, and 2960 entries were classified using the system. RESULTS: Our classification system featured 11 distinct descriptive categories, with media consumption being the most popular coping strategy among Beyond Now users, followed by relaxation and self-care activities, exercise and creative activities. More than half (57%) of the entries were suggested coping strategies with the remainder being user-generated entries (43%). CONCLUSION: A wide range of coping strategies were entered into safety plans, with activities that aim to either distract or provide reductions in emotional arousal common. Future research is needed to evaluate the efficacy of the coping strategies listed in safety plans.

RESUMEN

Background: Recent findings indicate that firefighters may be at increased risk for death by suicide; however, there has been only limited suicide prevention work in fire service to date. Aim: The objective of this program evaluation project was to develop and evaluate a web-based Safety Planning Intervention (SPI) training course for firefighter peer support specialists. Method: Peer support specialists who completed the web-based SPI training were administered evaluation questionnaires before the training and then again at a 3-month follow-up assessment. Results: A total of 213 peer support specialists completed the SPI training. Most participants took 2-3 h to complete the training. Participants generally reported high levels of satisfaction with the course, with the vast majority (94.4%) indicating they would recommend it to their peers. Course completers also demonstrated significant gains in SPI knowledge and self-efficacy from baseline to 3-month follow-up (all p's < .001). Moreover, the percentage of participants who reported completing a safety plan with someone they suspected at being of risk for suicide increased approximately 7-fold from baseline (3.5%) to 3-month follow-up (25.2%; p < .001). Participants further reported that 97.6% of the safety plans that they completed resulted in a positive outcome. Limitations: This was a program evaluation project that did not include a control group. Thus, causality cannot be inferred. Conclusions: The present findings suggest that web-based SPI training is a feasible and scalable approach for training peer support specialists to deliver the SPI to at-risk individuals.

RESUMEN

BACKGROUND: Pro-inflammatory cytokines such as interleukin (IL)-6 and tumor necrosis factor (TNF)-α are elevated in response to psychosocial stress; however, less is known about other inflammatory markers. METHODS: We explored response to the Trier Social Stress Test (TSST) of 16 cytokines and growth factors in patients with major depressive disorder (MDD, n = 12) vs. healthy volunteers (HV, n = 16). Outcomes were baseline and post-stress levels estimated by area under the curve (AUCi) and peak change over 3 timepoints. We also explored correlations between biomarkers and clinical characteristics. RESULTS: Baseline concentrations were higher in MDD for platelet-derived growth factor (PDGF)-AB/BB (p = 0.037, d = 0.70), granulocyte-macrophage colony-stimulating factor (GM-CSF, p = 0.033, d = 0.52), and IL-8 (p = 0.046, d = 0.74). After TSST, AUCi was higher in MDD for GM-CSF (p = 0.003, d = 1.21), IL-5 (p = 0.014, d = 1.62), and IL-27 (p = 0.041, d = 0.74). In MDD, depression severity correlated positively with soluble CD40L (sCD40L) for AUCi (Spearman's ρ = 0.76, p = 0.004) and with baseline vascular endothelial growth factor A (VEGFA, r = 0.85, p < 0.001), but negatively with baseline monokine induced by gamma interferon (MIG, aka CXCL9; r = -0.77, p = 0.003). CONCLUSIONS: Effect sizes were robust in this exploratory study, although interpretation of the results must be cautious, given small sample size and multiple comparisons. Differential study of stress-induced biomarkers may have important ramifications for MDD treatment.

RESUMEN

INTRODUCTION: Brief interventions that reduce suicide risk following youth's experience with acute care due to suicidality are needed. METHODS AND ANALYSIS: The study will use a three-arm randomised controlled trial designed to test the effectiveness of the Safety Planning Intervention with structured follow-up (SPI+) and the Collaborative Assessment and Management of Suicidality (CAMS) compared with enhanced usual care. The primary outcomes measure will be suicidal events, defined as death by suicide, attempted suicide, preparatory acts toward imminent suicidal behaviour or suicidal ideation resulting in a change in emergency evaluation or inpatient admission. Secondary measures will be the number of suicide attempts and severity of suicidal ideation. The experimental interventions, SPI+ and CAMS, consist of up to eight sessions over approximately 8 weeks that are designed to manage (SPI+) or treat (CAMS) patient-identified 'drivers' of suicidal thoughts and behaviours. Mechanisms and moderators of change will be evaluated to understand treatment impacts. ETHICS AND DISSEMINATION: This study has been approved by the Seattle Children's Institutional Review Board and is monitored by external agencies including the University of Washington Institute for Translational Health Sciences, and a National Institute of Mental Health (NIMH)-appointed Data Safety and Monitoring Board. Trial results will help establish evidence towards safe and effective treatment strategies for youth transitioning from acute to outpatient care due to a suicidal crisis. The data will be shared with the NIMH Data Archives and disseminated through publications and conferences. TRIAL REGISTRATION NUMBER: NCT05078970.

RESUMEN

Higher intent suicide attempts carry elevated risk of future suicidal behavior. Abnormal functioning of the hypothalamic-pituitary-adrenal (HPA) axis is both linked to nonfatal suicidal behavior and suicide deaths in major depressive disorder. Few studies, however, have identified biological markers of a high-intent suicidal subgroup. We examined HPA axis output and reactivity to the Trier Social Stress Test (TSST) via salivary cortisol in depressed individuals (N=68) with a suicide attempt (SA) history. A median split of higher and lower suicidal intent scores was used to define groups. Individuals with high intent SA had attenuated total cortisol output (AUCg), F(1,60)=10.04, SE=5.095, p=.003, and lower HPA-axis stress responsivity to the TSST (AUCi), F(1,60)=4.50, SE=4.604, p=.039, compared with the low intent SA group. The high intent group also reported more pronounced negative affect than the low intent group (F[1,61]=6.413, SE=10.55, p=.014) both at baseline (meandiff=22.32, p=.038) and in response to the stressor task (meandiff=37.62, p=.003). Vulnerability to suicidal behavior in high-intent individuals may be related to the combined profile of impaired physiological responses to stress and greater negative affectivity. This clinical and biologic subgroup may benefit from targeted suicide prevention interventions.

RESUMEN

The rising rates of suicide warrant effective treatments that can quickly help stabilize suicidal individuals and prevent future suicidal crises from occurring. Across the past few decades, there has been a rise in the development of ultra-brief (1-4 sessions) and brief suicide-specific interventions (6-12 sessions) to meet this need. This article reviews several prominent ultra-brief and brief interventions, including the Teachable Moment Brief Intervention, Attempted Suicide Short Intervention Program, Safety Planning Intervention, Crisis Response Planning, Cognitive Therapy for Suicide Prevention, Brief Cognitive-Behavioral Therapy for Suicide Prevention, Collaborative Assessment and Management of Suicidality, and the Coping Long-Term With Active Suicide Program. A brief review of each interventions' evidence base is also provided. Current challenges and directions for future research in testing the efficacy and effectiveness of suicide prevention initiatives are discussed.

RESUMEN

Knowledge on how suicidal ideation (SI) varies following first episode psychosis (FEP) onset is scarce. We identified 1-year trajectories of SI and baseline predictors of emergent SI among all 1298 clients aged 16-30 years enrolled between October 2013-December 2018 in OnTrackNY, a program providing early intervention services for FEP across New York State. Clinicians recorded baseline clinical and sociodemographic variables and quarterly assessments of SI over a one-year follow-up. We examined baseline correlates of baseline SI and of 1-year SI trajectory. Among clients not reporting baseline SI, we examined predictors of subsequent emergent SI. Baseline SI was reported by 349 (26.9 %) clients and associated with schizoaffective disorder, previous self-injurious behavior, any alcohol or substance use, higher symptom severity, poorer social functioning, and Non-Hispanic White, Asian or Hispanic ethnoracial background. Two hundred and two (15.6 % overall) clients stopped being suicidal within 6 months of follow-up. Persistent SI was reported by 147 (11.3 % overall) clients and, among clients not discharged before one year of follow-up, was associated with schizoaffective disorder, any alcohol use, being female, and being Hispanic or White Non-Hispanic. Among 949 (73.1 %) clients not reporting baseline SI, subsequent emergent SI was reported by 139 (10.7 % overall) and predicted at baseline by schizoaffective disorder, higher symptom severity, recent homelessness, and not being Hispanic. In conclusion, SI is highly prevalent and varies markedly over time among FEP early intervention clients. These results highlight the importance of ongoing assessment for SI among individuals experiencing FEP - even in the absence of baseline SI.

RESUMEN

BACKGROUND: Borderline personality disorder (BPD) is characterized by an elevated distress response to social exclusion (i.e., rejection distress), the neural mechanisms of which remain unclear. Functional magnetic resonance imaging studies of social exclusion have relied on the classic version of the Cyberball task, which is not optimized for functional magnetic resonance imaging. Our goal was to clarify the neural substrates of rejection distress in BPD using a modified version of Cyberball, which allowed us to dissociate the neural response to exclusion events from its modulation by exclusionary context. METHODS: Twenty-three women with BPD and 22 healthy control participants completed a novel functional magnetic resonance imaging modification of Cyberball with 5 runs of varying exclusion probability and rated their rejection distress after each run. We tested group differences in the whole-brain response to exclusion events and in the parametric modulation of that response by rejection distress using mass univariate analysis. RESULTS: Although rejection distress was higher in participants with BPD (F1,40 = 5.25, p = .027, η2 = 0.12), both groups showed similar neural responses to exclusion events. However, as rejection distress increased, the rostromedial prefrontal cortex response to exclusion events decreased in the BPD group but not in control participants. Stronger modulation of the rostromedial prefrontal cortex response by rejection distress was associated with higher trait rejection expectation, r = -0.30, p = .050. CONCLUSIONS: Heightened rejection distress in BPD might stem from a failure to maintain or upregulate the activity of the rostromedial prefrontal cortex, a key node of the mentalization network. Inverse coupling between rejection distress and mentalization-related brain activity might contribute to heightened rejection expectation in BPD.

RESUMEN

We examined relationships between the serotonin system and stress in major depression and suicidal behavior. Twenty-five medication-free depressed participants (13 suicide attempters) underwent same-day [11C]DASB and [11C]CUMI-101 positron emission tomography (PET) imaging. Binding potential (BPND) to the serotonin transporter (5-HTT) and serotonin 1A (5-HT1A) receptor, respectively, was quantified using the NRU 5-HT atlas, reflecting distinct spatial distributions of multiple serotonin targets. Ecological momentary assessment (EMA) measured current stress over one week proximal to imaging. EMA stress did not differ between attempters and non-attempters. In all depressed participants, 5-HTT and 5-HT1A BPND were unrelated to EMA stress. There were region-specific effects of 5-HTT (p=0.002) and 5-HT1A BPND (p=0.03) in attempters vs. nonattempters. In attempters, region-specific associations between 5-HTT (p=0.03) and 5-HT1A (p=0.005) BPND and EMA stress emerged. While no post-hoc 5-HTT BPND correlations were significant, 5-HT1A BPND correlated positively with EMA stress in attempters in 9/10 regions (p-values<0.007), including the entire cortex except the largely occipital region 5. Brodmann-based regional analyses found diminished effects for 5-HTT and subcortically localized positive corrrelations between 5-HT1A and EMA stress, in attempters only. Given comparable depression severity and childhood and current stress between attempters and nonattempters, lower 5-HTT binding in attempters vs. nonattempters may suggest a biological risk marker. Localized lower 5-HTT and widespread higher 5-HT1A binding with stress among attempters specifically may suggest that a serotonergic phenotype might be a key determinant of risk or resiliency for suicidal behavior.

RESUMEN

Minimal evidence exists for suicide-specific group treatment for high-risk patients offered over telehealth. This qualitative study assessed the acceptability, feasibility, and impact of a telehealth suicide safety planning intervention (SPI) multi-session group. High-risk suicidal Veterans (n = 17) participating in "Project Life Force-telehealth" (PLF-T); a manualized, 10-session SPI video group completed semi-structured qualitative interviews including measures of acceptability, appropriateness, and feasibility. We also interviewed the PLF-T coordinator and PLF-T group facilitators to identify adaptations to deliver PLF-T and learn about barriers and facilitators to implementation. A summary template and matrix analysis approach was used to analyze qualitative data. Veteran group participants were mostly male (88%), age 50 (SD = 15.6), ethnically diverse, and either divorced or separated (54%). Suicide symptoms upon study entry included past month ideation with methods (100%); and past year aborted, interrupted, or actual suicide attempt (59%). Participant interviews revealed an overall positive endorsement of PLF-telehealth with enhanced suicidal disclosure, and improved ability to manage urges and mitigate loneliness. On scales from 1 to 20, PLF-T was rated as highly acceptable (M = 17.50; SD = 2.92), appropriate (M = 17.25; SD = 3.59), and feasible (M = 18; SD = 2.45) by participants. Adaptations to deliver PLF-T included using a communications coordinator to conduct assertive outreach and engagement, adding a telehealth orientation session, restructuring sessions to review suicide severity, and screen-sharing safety plans to maximize learning. PLF-T enhanced convenience and access without compromising safety. Concerns included privacy and technological limitations including connectivity. Project Life Force-telehealth is acceptable and feasible to deliver via telehealth. This opens the possibility of delivery to hard-to-reach high-risk populations.

RESUMEN

BACKGROUND: Emotion regulation (ER) processes help support well-being, but ineffective ER is implicated in several psychiatric disorders. Engaging ER flexibly by going online and offline as needs and capacities shift may be more effective than engaging ER rigidly across time. Here, we sought to observe the neural temporal dynamics of an ER process, reappraisal, during regulation of responses to negative memories in healthy control subjects (n = 33) and subjects with major depressive disorder (n = 36). METHODS: To track the temporal dynamics of reappraisal neural systems, we used a functional magnetic resonance imaging neural decoding approach. In task 1, subjects explicitly engaged reappraisal on instruction in response to aversive images, and we used this task to develop the decoder for detecting reappraisal. In task 2, subjects experienced negative autobiographical memories from a distant (third person, ER condition) or immersed (first person, control condition) perspective. RESULTS: The neural decoder, trained to detect reappraisal in task 1, predicted greater reappraisal occurring during the task 2 distance versus immerse trials and was engaged more intensely during memories that were rated as being more negative. Across time, decoder output manifested a temporal dynamic of early engagement followed by disengagement. These results were replicated in an independent subject dataset (n = 59). Relative to healthy control subjects, subjects with major depressive disorder had a comparable initial increase in decoder engagement at the beginning of the trial but an attenuated decrease at the end. CONCLUSIONS: Subjects with major depressive disorder evidenced a more rigid neural dynamic of reappraisal compared with healthy control subjects. Rigid ER may indicate diminished ability to flexibly and effectively regulate emotion.

RESUMEN

Suicidal behavior is associated with deficits in cognitive control; however, suicidal ideation (SI), a key precursor to suicidal behavior, has been less consistently linked to neuropsychological functioning. Additionally, no study to date has examined attentional control capacities in relation to variability in suicidal ideation, defined as fluctuation in SI intensity and duration across short periods of time. Prior research suggests that suicidal individuals with highly variable SI experience greater stress-responsive increases in SI and cortisol, potentially raising risk for suicidal behavior. Here, we examined attentional control capacities associated with SI variability and severity in ninety-five subjects with major depressive disorder. Variability and severity of SI and depressive affect were quantified using Ecological Momentary Assessment (EMA) over a 7-day period. Participants completed the Continuous Performance Task (CPT) and a computerized Stroop task for assessment of attentional control. EMA SI variability was associated with greater attentional interference on the Stroop task, and this was not accounted for by severity of SI, concurrently assessed depressive affect, or baseline depression. CPT performance was not related to SI variability or intensity. Findings highlight the utility of EMA methods in characterizing patterned experiences of SI and suggest that attentional control deficits may contribute to these characteristic patterns.

RESUMEN

BACKGROUND: Neurocognitive testing may advance the goal of predicting near-term suicide risk. The current study examined whether performance on a Go/No-go (GNG) task, and computational modeling to extract latent cognitive variables, could enhance prediction of suicide attempts within next 90 days, among individuals at high-risk for suicide. METHOD: 136 Veterans at high-risk for suicide previously completed a computer-based GNG task requiring rapid responding (Go) to target stimuli, while withholding responses (No-go) to infrequent foil stimuli; behavioral variables included false alarms to foils (failure to inhibit) and missed responses to targets. We conducted a secondary analysis of these data, with outcomes defined as actual suicide attempt (ASA), other suicide-related event (OtherSE) such as interrupted/aborted attempt or preparatory behavior, or neither (noSE), within 90-days after GNG testing, to examine whether GNG variables could improve ASA prediction over standard clinical variables. A computational model (linear ballistic accumulator, LBA) was also applied, to elucidate cognitive mechanisms underlying group differences. RESULTS: On GNG, increased miss rate selectively predicted ASA, while increased false alarm rate predicted OtherSE (without ASA) within the 90-day follow-up window. In LBA modeling, ASA (but not OtherSE) was associated with decreases in decisional efficiency to targets, suggesting differences in the evidence accumulation process were specifically associated with upcoming ASA. CONCLUSIONS: These findings suggest that GNG may improve prediction of near-term suicide risk, with distinct behavioral patterns in those who will attempt suicide within the next 90 days. Computational modeling suggests qualitative differences in cognition in individuals at near-term risk of suicide attempt.

RESUMEN

ABSTRACT: Some patients engage in self-harm behaviors while in the emergency department. Risk factors for self-harm have been described for inpatient and outpatient/community settings, but not among emergency department patients. Authors conducted case-control, retrospective reviews of medical records and incident reports for emergency department patients in two academic medical centers. Variables were analyzed using conditional logistic regression. There were 113 individuals who engaged in self-harm while in the emergency department and 226 individuals who did not. Four variables were significant in the final model: a history of nonsuicidal self-harm (odds ratio [OR], 4.28; 95% confidence interval [CI], 1.95-9.41), opioid use in the prior 2 weeks (OR, 2.89; CI, 1.19-7.02), current manic episode (OR, 3.59; CI, 1.33-9.70), and a history of seizures (OR, 4.19; CI, 1.16-15.14). Risk of self-harm while in the emergency department may be mitigated with interventions that support adaptive coping skills, promptly address pain and withdrawal symptoms, and treat mania.

RESUMEN

BACKGROUND: A previous suicide attempt is an important predictor of future suicide. However, there are no evidence-based interventions administered in UK general hospital contexts to reduce suicidal behaviour in patients admitted following a suicide attempt. Consequently, the objective of this pilot randomised controlled trial was to explore whether a safety planning and telephone follow-up intervention (SAFETEL) was feasible and acceptable for individuals treated in hospital following a suicide attempt. METHODS: In this three-phase study with an embedded process evaluation, a safety planning intervention was tailored to the UK context (Phase I), piloted (Phase II, n = 32), and tested in a feasibility randomised controlled trial (Phase III). In Phase III, participants were allocated to either the intervention (n = 80) or control group (n = 40) using telephone randomisation with a 2:1 ratio. The acceptability and feasibility of the trial and intervention procedures were evaluated using both qualitative (interviews and focus groups) and quantitative data. The number of hospital representations of suicidal behaviour was also collected 6 months after study recruitment based on electronic patient records. RESULTS: Findings indicated that SAFETEL was both acceptable and feasible. Hospital staff reported the intervention fitted and complemented existing services, and patients reported that they favoured the simplicity and person-centred approach of the safety planning intervention. CONCLUSIONS: All progression criteria were met supporting further evaluation of the intervention in a full-scale clinical effectiveness trial. TRIAL REGISTRATION: ISRCT, ISRCTN62181241 , 5/5/2017.

RESUMEN

INTRODUCTION: The loss of a patient to suicide has an enormous impact on clinicians, but few studies have examined its effects. METHOD: In this retrospective study, we compared clinicians who have and have not experienced a patient suicide using a survey of 2157 outpatient clinicians from 169 New York clinics to determine differences in their suicide prevention knowledge, practices, training, and self-efficacy. RESULTS: Approximately 25% of the clinician respondents lost patients to suicide; psychiatrists, nurses/nurse practitioners, and those with more years of experience were disproportionately affected. After controlling for these demographic/professional differences, clinicians who had experienced patient suicide reported feeling that they had insufficient training, despite actually having more suicide prevention training, greater knowledge of suicide prevention practices, and feeling more comfortable working with suicidal patients than clinicians who had not lost a patient to suicide. There were no differences in self-efficacy or utilization of evidence-based clinical practices. CONCLUSIONS: Controlling for demographic/professional differences, clinicians who experienced a patient suicide had more training, knowledge, and felt more comfortable working with suicidal patients. It is critical that sufficient training be available to clinicians, not only to reduce patient deaths, but also to help clinicians increase their comfort, knowledge, skill, and ability to support those bereaved by suicide loss.
