Direct costs of hospital care of self-harm: A national register-based cohort study

Associations between physical activities and self-harm behaviour in depression across the genotype: findings from the UK biobank

BACKGROUND

Physical activities are widely implemented for non-pharmacological intervention to alleviate depressive symptoms. However, there is little evidence supporting their genotype-specific effectiveness in reducing the risk of self-harm in patients with depression.

AIMS

To assess the associations between physical activity and self-harm behaviour and determine the recommended level of physical activity across the genotypes.

METHOD

We developed the bidirectional analytical model to investigate the genotype-specific effectiveness on UK Biobank. After the genetic stratification of the depression phenotype cohort using hierarchical clustering, multivariable logistic regression models and Cox proportional hazards models were built to investigate the associations between physical activity and the risk of self-harm behaviour.

RESULTS

A total of 28 923 subjects with depression phenotypes were included in the study. In retrospective cohort analysis, the moderate and highly active groups were at lower risk of self-harm behaviour. In the followed prospective cohort analysis, light-intensity physical activity was associated with a lower risk of hospitalisations due to self-harm behaviour in one genetic cluster (adjusted hazard ratio, 0.28 [95% CI, 0.08-0.96]), which was distinguished by three genetic variants: rs1432639, rs4543289 and rs11209948. Compliance with the guideline-level moderate-to-vigorous physical activities was not significantly related to the risk of self-harm behaviour.

CONCLUSIONS

A genotype-specific dose of light-intensity physical activity reduces the risk of self-harm by around a fourth in depressive patients.

Trajectory of Non-suicidal Self-Injury among adolescents with borderline personality disorder over a 5-year period

BACKGROUND

Engagement in Non-Suicidal Self-Injury (NSSI) is high among adolescents with borderline personality disorder (BPD), but the trajectory of NSSI in the transition period from adolescence to adulthood is unclear, and studies that look at predictors of persistence are highly needed.

METHODS

This study followed 111 adolescents aged 14-17 with BPD over a five-year period to observe the prevalence and predictors of NSSI. Information on NSSI was based on both self-report and clinician-administered interviews.

RESULTS

At the outset, 92.8% reported a history of NSSI, with an average of nearly five different types of NSSI. Despite this high initial prevalence, the rates of NSSI within the past two weeks decreased over time from 48% at baseline to 26% after one year, and further to 10% after two years. After five years, 37% reported engaging in NSSI within the past six months. Notably, all but one participant who reported NSSI after five years had engaged in NSSI already at baseline. The study identified that higher adolescent-rated but lower parent-rated BPD severity was associated with engagement in NSSI at baseline. Furthermore, ongoing NSSI after five years was predicted by lower parent-rated BPD severity and externalizing behaviors.

CONCLUSIONS

NSSI is frequent in the early course of BPD, and persists in more than one-third after five years. Our findings highlight that baseline engagement in NSSI is a risk factor for persistence of NSSI in the transition period into early adulthood. Furthermore, the findings underscore the significance of integrating both adolescent and parent perspectives on BPD pathology in the assessment and management of NSSI.

Cost-effectiveness of psychological and psychosocial interventions for adults, children and young people who have self-harmed

BACKGROUND

Self-harm is a major health issue resulting in high societal costs. Few psychological and psychosocial interventions have shown effectiveness in reducing repeat self-harm.

OBJECTIVE

To assess the cost-effectiveness of psychological and psychosocial interventions that have shown evidence of effectiveness in adults and CYP (children and young people) who have self-harmed.

METHODS

Using effectiveness data from Cochrane reviews, we developed two decision-analytical models to compare costs and quality-adjusted life years (QALYs) of cognitive behavioural therapy (CBT)-informed psychological therapy added to treatment as usual (TAU) versus TAU alone for adults who have self-harmed, and of dialectical behavioural therapy for adolescents (DBT-A) versus enhanced TAU for CYP who have self-harmed, respectively, from a National Health Service and personal social services perspective in England. Other model input parameters were obtained from published sources, supplemented by expert opinion.

FINDINGS

The incremental cost-effectiveness ratio (ICER) of CBT-informed psychological therapy added to TAU versus TAU alone for adults who have self-harmed was £9088/QALY. The ICER of DBT-A versus enhanced TAU for CYP who have self-harmed was £268 601/QALY. Results were overall robust to the alternative scenarios tested.

CONCLUSIONS AND CLINICAL IMPLICATIONS

CBT-informed psychological therapy appears to be cost-effective for adults who have self-harmed, which contributes to evidence for its implementation in services. Currently, DBT-A does not seem to be cost-effective for CYP who have self-harmed. The economic analyses were informed by clinical evidence of moderate-to-low (CBT) and low (DBT-A) quality. Further clinical and economic evidence for DBT-A and other psychological and psychosocial interventions for people who have self-harmed is required.

Brief admission by self-referral as an add-on to usual care for individuals with self-harm at risk of suicide: cost-effectiveness and 4-year health-economic consequences after a Swedish randomized controlled trial

BACKGROUND

Brief Admission by self-referral (BA) is a crisis-management intervention standardized for individuals with self-harm at risk of suicide. We analyzed its health-economic consequences.

MATERIALS AND METHODS

BA plus treatment as usual (TAU) was compared with TAU alone in a 12-month randomized controlled trial with 117 participants regarding costs for hospital admissions, coercive measures, emergency care and health outcomes (quality-adjusted life years; QALYs). Participants were followed from 12 months before baseline to up to five years after.

RESULTS

Over one year BA was associated with a mean annual cost reduction of 4800 or incremental cost of 4600 euros, depending on bed occupancy assumption. Cost-savings were greatest for individuals with >180 admission days in the year before baseline. In terms of health outcomes BA was associated with a QALY gain of 0.078. Uncertainty analyses indicated a significant QALY gain and ambiguity in costs, resulting in BA either dominating TAU or costing 59 000 euros per gained QALY.

CONCLUSION

BA is likely to produce QALY gains for individuals living with self-harm and suicidality. Cost-effectiveness depends on targeting high-need individuals and comparable bed utilization between BA and other psychiatric admissions. Future research should elaborate the explanatory factors for individual variations in the usage and benefit of BA.

Left with a Sisyphean task - the experiences of nurse practitioners with treating non-suicidal self-injury in the emergency department: a descriptive qualitative study

BACKGROUND

Non-suicidal self-injury (NSSI) is a prevalent phenomenon in somatic emergency departments, where nurses are the most consistent group of healthcare professionals who treat people with NSSI, which means they may affect the NSSI trajectory and help-seeking in the future. The objective of this study was to describe the experiences of nurse practitioners with treatment of people presenting with NSSI in the emergency department.

METHODS

Individual, semi-structured telephone interviews were conducted with seventeen purposefully recruited nurse practitioners from three emergency departments in the Capital Region of Denmark. Interview transcripts were analysed using inductive content analysis, as described by Graneheim and Lundman.

RESULTS

The analysis resulted in the formulation of three categories and 10 subcategories describing how nurse practitioners feel confident and competent in treating physical injuries due to NSSI but at the same time insecure about how to provide adequate care and engage in conversations about NSSI and mental wellbeing with people with NSSI. An overarching theme, 'Left with a Sisyphean task', reflects the nurses' feeling of being handed the responsibility for performing a laborious, never-ending, and futile task.

CONCLUSION

The findings indicate that nurse practitioners feel confident and competent in treating physical injuries due to NSSI but insecure about how to provide adequate care. Therefore, there is a need for training and guidelines.

Does self-harm have the desired effect? Comparing non-suicidal self-injury to high-urge moments in an ambulatory assessment design

All theoretical models of non-suicidal self-injury (NSSI) posit that regulation of negative affect (NA) is a central motive for NSSI, and cross-sectional work supports this. However, previous ambulatory assessment (AA) studies that examined NSSI found mixed results. We investigated the affect regulation function of NSSI in 51 women with DSM-5 NSSI disorder in a 15-day AA study with five random daily prompts and self-initiated NSSI prompts. We extend previous work by i) comparing NSSI moments to moments of a high-urge for NSSI, ii) adding high-frequency sampling following NSSI and high-urge moments, and iii) including tension as a dependent variable. We hypothesized that NA and tension would show a steeper decrease following NSSI than following high-urge moments, if NSSI was effective in reducing NA and tension. Results showed that the significant linear NA decline following NSSI was not steeper than that following high-urge moments. For aversive tension, we found that NSSI was associated with a significant linear decrease in tension, whereas resisting an urge was not. High-urge moments were better described by an inverted U-shaped pattern, likewise leading to decreased NA and tension following the reported urge. In exploratory analyses, we provide visualized clustering of the NA and tension trajectories surrounding NSSI using k-means and relate these to participants' self-rated effectiveness of the NSSI events. Findings indicate that resisting an urge may also be effective in managing NA and tension and underline the utility of interventions such as urge-surfing.

Healthcare resource utilization prior to suicide death or suicide attempt in patients with major depressive disorder-A Danish registry-based cohort study

INTRODUCTION

Major depressive disorder (MDD) is associated with suicide events and with increased healthcare resource utilization (HRU). The aim was to analyze the pattern of HRU prior to death by suicide or suicide attempt in patients with MDD using national registries.

METHODS

Danish adults with MDD, who died by suicide or had a first-time suicide attempt, were matched with MDD controls on age, sex, and MDD severity and analyzed for psychiatric and non-psychiatric hospital and private practitioner contacts, and prescriptions 1 year prior to the event. For individuals having a second suicide attempt, HRU prior to first and second suicide attempt was analyzed.

RESULTS

Among 1061 individuals dying by suicide and 3759 individuals with suicide attempt, compared with their controls, the proportion with psychiatric hospitalization was more than 50% increased, mainly accounted for by acute contacts. The difference to the matched controls decreased with increasing MDD severity. Non-psychiatric HRU was increased as well. The proportion with psychiatric hospitalizations or ED visits was reduced prior to the second attempt compared with first attempt.

CONCLUSION

Among individuals with MDD, psychiatric and non-psychiatric HRU was increased 1 year prior to suicide event. The proportion of individuals who had psychiatric HRU decreased from first to second suicide attempt.
