Safety Planning for Suicidality in Autism: Obstacles, Potential Solutions, and Future Directions

Use of ECT for Children With and Without Catatonia: A Single-Site Retrospective Analysis

OBJECTIVES

The objective study was to investigate the safety and efficacy of electroconvulsive therapy (ECT) in a retrospective cohort of pediatric patients.

METHODS

A single-site retrospective analysis was conducted of patients aged younger than 18 years who received ECT in a private university hospital from January 28, 2012 to April 8, 2023. Treatment efficacy and adverse events were determined retrospectively through review of the medical record.

RESULTS

A total of 36 pediatric patients met the inclusion criteria. Catatonia was the most common presenting indication for ECT, followed by psychosis and suicidal ideation. For all patients, Clinical Global Impressions-Improvement scale scores indicated that it was very likely for a subject to experience at least "much improvement" with the estimated probability of receiving a Clinical Global Impressions-Improvement scale score better than 3 of 0.852 (t.s. = 16.3; P < 0.001; 95% confidence interval, 0.711-0.931). All patients with catatonia demonstrated a positive clinical response and experienced a statistically significant reduction in total Bush-Francis Catatonia Rating Scale scores observed ( t = 11.9; df = 20; SD = 6.3; P < 0.001; 95% confidence interval, 12.6-17.9). No significant adverse events were reported for any patient in the cohort. However, 14 (38.9%) patients experienced prolonged seizures, all of which were terminated with propofol (mean, 49.7 mg).

CONCLUSIONS

This study provides further data supporting the safe and effective use of pediatric ECT in the treatment of various psychiatric conditions. However, more research is needed to determine the risk factors associated with prolonged seizures and the optimal seizure parameters in young people.

Feasibility and acceptability of autism adapted safety plans: an external pilot randomised controlled trial

Background

Autistic people are a high-risk group for self-harm and suicide. There are no evidence-based suicide prevention interventions developed specifically for autistic people. We undertook a pilot feasibility randomised controlled trial of autism adapted safety plans (AASP) to reduce self-harm and suicide for autistic people.

Methods

This study took place in the United Kingdom and followed a randomised, two-arm, controlled design. Autistic adults (n = 53, mean age = 39, gender = 49% female, 29% not male or female) were recruited via third sector organisations and self-referral between 11.8.21 and 19.10.22. Participants were randomised without stratification to usual care with or without AASP. The AASP was completed by the autistic adults together with someone trained to support them. Research staff who completed follow-up assessments were blind to participant allocation. Primary outcomes were feasibility and acceptability. Participants were assessed at baseline, 1 and 6 months. Primary data were analysed under the intention to treat principle. Study protocol is published. The trial is closed to new participants. This study is registered with the ISRCTN registry, ISRCTN70594445.

Findings

53 participants consented, 49 were randomised to either AASP with usual care (n = 25) or usual care (n = 24). 68% of participants in the AASP arm were satisfied with the AASP and 41% rated it as useable. Feedback on the AASP and research methods were positive with suggested adaptations to some outcome measures. Retention and completion of outcomes measures in both arms was excellent, as was fidelity of delivery of the AASP.

Interpretation

Study progression criteria were met, suggesting that the parameters of a future definitive trial of clinical and cost effectiveness of AASP to reduce self-harm and suicide in autistic adults are achievable, with minor recommended adaptions to outcome measures and AASP. Future research should explore the use of AASP in routine clinical practice.

Funding

This study is funded by the NIHR [Public Health Research Programme (NIHR129196)].

Improving Emergency Department Care for Suicidality in Autism: Perspectives from Autistic Youth, Caregivers, and Clinicians

ABSTRACT: Purpose: Emergency department (ED) visits for suicidal ideation and self-harm are more prevalent in autistic than non-autistic youth. However, providers are typically offered insufficient guidance for addressing suicide risk in autistic youth, likely impacting confidence and care.

METHODS

In this pilot study, we conducted semi-structured interviews with 17 key members of the autism community (i.e., autistic youth with a history of suicidality, caregivers of autistic youth with a history of suicidality, autism specialist clinicians, ED clinicians) to inform the development of recommendations for modifying ED care for autistic patients, with a focus on suicide risk screening and management.

RESULTS

Participants reported on challenges they encountered receiving or providing care and/or recommendations for improving care. Participant perspectives were aligned, and four main categories emerged: accounting for autism features, connection and youth engagement in care, caregiver and family involvement, and service system issues.

CONCLUSION

As research continues in the development of autism-specific suicide risk assessment tools and management strategies, it is essential we better equip providers to address suicide risk in autistic patients, particularly in ED settings.

Autistic traits in adolescents in psychiatric inpatient care: Clinical and demographic characteristics and correlates

Background

Rates of psychiatric hospitalization among adolescents in the United States are rising, with many adolescents presenting to these settings with diverse clinical presentations, including autistic traits. To our knowledge, there has been little research identifying clinical characteristics of adolescents with autistic traits admitted to psychiatric inpatient units, which may be leveraged to improve assessment and treatment practices.

Method

In the current study, we examined clinical and demographic characteristics of 195 adolescents admitted to an adolescent psychiatric inpatient unit. Specifically, we investigated the prevalence of adolescents endorsing elevated autistic traits and tested associations between autistic traits, psychiatric symptoms (anxiety, depression, suicidal thoughts), and key demographic variables (age, sex, gender, sexual orientation).

Results

Results show that over half of the adolescents admitted to the psychiatric inpatient unit reported elevated autistic traits on a short screening questionnaire. Higher autistic traits were significantly associated with more severe depressive symptoms, though to a small degree. Autistic traits were not associated with anxiety symptoms, suicidal thoughts, nor social disconnectedness, and did not differ by sex, gender identity, nor sexual orientation.

Conclusions

Findings highlight the challenge of diagnostic overshadowing among adolescents in crisis and the need for more rigorous measures designed for an inpatient setting to improve risk stratification, clinical assessments, intervention approaches, and discharge planning.

Use of ECT in Autism Spectrum Disorder and/or Intellectual Disability: A Single Site Retrospective Analysis

Autism spectrum disorder (ASD) and intellectual disability (ID) are heterogenous and prevalent conditions which may occur in isolation or as a co-morbidity. Psychiatric co-morbidity is common with limited treatment options. Preliminary research into electroconvulsive therapy (ECT) for these conditions has been encouraging. Thus, further research in this patient population is warranted. We conducted a 10-year retrospective review of the electronic medical record and identified intellectually capable individuals with ASD (IC-ASD), and those with ASD+ID or ID who received at least three ECT treatments. 32 patients were identified of which 30 (94%) experienced positive clinical response, defined as a clinical global impression-improvement (CGI-I) score of 3 or less. The average retrospective CGI-I score across all groups was 1.97, and results of a t-test performed on CGI-I scores indicated improvement across all groups [t = - 16.54, df = 31, p < 0.001, 95% CI = (1.72, 2.22)]. No significant adverse events were identified based on clinical documentation. Our findings further support previous ECT research in this patient population.

Treatment Response of Transcranial Magnetic Stimulation in Intellectually Capable Youth and Young Adults with Autism Spectrum Disorder: A Systematic Review and Meta-Analysis

To examine current clinical research on the use of transcranial magnetic stimulation (TMS) in the treatment of pediatric and young adult autism spectrum disorder in intellectually capable persons (IC-ASD). We searched peer-reviewed international literature to identify clinical trials investigating TMS as a treatment for behavioral and cognitive symptoms of IC-ASD. We identified sixteen studies and were able to conduct a meta-analysis on twelve of these studies. Seven were open-label or used neurotypical controls for baseline cognitive data, and nine were controlled trials. In the latter, waitlist control groups were often used over sham TMS. Only one study conducted a randomized, parallel, double-blind, and sham controlled trial. Favorable safety data was reported in low frequency repetitive TMS, high frequency repetitive TMS, and intermittent theta burst studies. Compared to TMS research of other neuropsychiatric conditions, significantly lower total TMS pulses were delivered in treatment and neuronavigation was not regularly utilized. Quantitatively, our multivariate meta-analysis results report improvement in cognitive outcomes (pooled Hedges' g = 0.735, 95% CI = 0.242, 1.228; p = 0.009) and primarily Criterion B symptomology of IC-ASD (pooled Hedges' g = 0.435, 95% CI = 0.359, 0.511; p < 0.001) with low frequency repetitive TMS to the dorsolateral prefrontal cortex. The results of our systematic review and meta-analysis data indicate that TMS may offer a promising and safe treatment option for pediatric and young adult patients with IC-ASD. However, future work should include use of neuronavigation software, theta burst protocols, targeting of various brain regions, and robust study design before clinical recommendations can be made.

All-cause mortality and suicide mortality in autistic individuals: An entire population longitudinal study in Taiwan

LAY ABSTRACT

Our study was the first population-based study in an Asian country to investigate the mortality rates among autistic individuals. Among the entire Taiwanese population (N = 29,253,529), between 2003 and 2017, 45,398 autistic individuals were identified and 1:4 age-/sex-matched to 181,592 non-autistic individuals. We found that autistic individuals had increased risks of all-cause mortality, natural-cause mortality, and suicide mortality compared with non-autistic individuals. Furthermore, autistic males were more likely to die by suicide, and autistic females were more likely to die of accident compared with the non-autistic individuals.

The role of anxiety and depression in suicidal thoughts for autistic and non-autistic people: A theory-driven network analysis

BACKGROUND

Autistic adults experience more frequent suicidal thoughts and mental health difficulties than non-autistic adults, but research has yet to explain how these experiences are connected. This study explored how anxiety and depression contribute to suicidal thoughts according to the Interpersonal Theory of Suicide for autistic and non-autistic adults.

METHODS

Participants (autistic adults n = 463, 61% female; non-autistic n = 342, 64% female) completed online measures of anxiety, depression, thwarted belonging, and perceived burdensomeness. Network analysis explored whether: (i) being autistic is a risk marker for suicide; and (ii) pathways to suicidal thoughts are consistent for autistic and non-autistic adults.

RESULTS

Being autistic connected closely with feeling like an outsider, anxiety, and movement, which connected to suicidal thoughts through somatic experiences, low mood, and burdensomeness. Networks were largely consistent for autistic and non-autistic people, but connections from mood symptoms to somatic and thwarted belonging experiences were absent for autistic adults.

CONCLUSION

Autistic people experience more life stressors than non-autistic people leading to reduced coping, low mood, and suicidal thoughts. Promoting belonging, reducing anxiety, and understanding the role of movement could inform suicide prevention for autistic people. Research should accurately capture autistic lived experience when modeling suicide to ensure suicide prevention meets autistic needs.

Mental health service availability for autistic youth in New York City: An examination of the developmental disability and mental health service systems

LAY ABSTRACT

Autistic children and adolescents experience high rates of co-occurring mental health conditions, including depression and suicidality, which are frequently identified by stakeholders as treatment priorities. Unfortunately, accessing community-based mental health care is often difficult for autistic youth and their families. The first obstacle families confront is finding a provider that offers mental health treatment to autistic youth within the many service systems involved in supporting the autism community. The mental health and developmental disability systems are two of the most commonly accessed, and previous work has shown there is often confusion over which of these systems is responsible for providing mental health care to autistic individuals. In this study, we conducted a telephone survey to determine the availability of outpatient mental health services for autistic youth with depressive symptoms or suicidal thoughts or behaviors in New York City across the state's mental health and developmental disability systems. Results showed that while a greater percentage of clinics in the mental health system compared with in the developmental disability system offered outpatient mental health services to autistic youth (47.1% vs 25.0%), many more did not offer care to autistic youth and there were very few options overall. Therefore, it is important that changes to policy are made to increase the availability of services and that mental health care providers' knowledge and confidence in working with autistic youth are improved.

Behavioral Management of Children With Autism in the Emergency Department

ABSTRACT

Autism spectrum disorder (ASD) is characterized by impaired social communication in conjunction with patterned behaviors. Often associated with emotional dysregulation, irritability, aggression, depression, and suicidality, ASD youth frequently present to the emergency department for behavioral and mental health evaluation. Psychiatric comorbidities, agitation, and depression are commonly encountered. During these visits, practitioners must thoughtfully consider organic etiologies for presenting symptoms, formulate plans to address risk of agitation, and understand how to effectively formulate disposition options in this patient population.

Assessing and Managing Suicide Risk in Autistic Youth: Findings from a Clinician Survey in a Pediatric Psychiatric Emergency Setting

Suicidal thoughts and behaviors (STB) and emergency department (ED) utilization are prevalent in autistic youth. The current study surveyed clinicians in a pediatric psychiatric ED to examine differences in attitudes on suicide-related care for autistic and non-autistic patient populations. While clinicians rated addressing STB in ASD as important and adaptations to care as necessary, less than half identified ASD as a suicide risk factor and confidence ratings were significantly lower for autistic patients. Previous ASD training predicted confidence and accounted for approximately 25% of the variance in confidence scores. Findings highlight the urgency to develop and disseminate ED clinician training, and address the lack of validated assessment tools, adapted suicide prevention practices, and evidence-based treatments for STB in autistic youth.
