Relationship between prescribed psychotropic medications and co-ingested alcohol in intentional self-poisonings

Premature mortality in young people accessing early intervention youth mental healthcare: data-linkage cohort study

BACKGROUND

Understanding premature mortality risk from suicide and other causes in youth mental health cohorts is essential for delivering effective clinical interventions and secondary prevention strategies.

AIMS

To establish premature mortality risk in young people accessing early intervention mental health services and identify predictors of mortality.

METHOD

State-wide data registers of emergency departments, hospital admissions and mortality were linked to the Brain and Mind Research Register, a longitudinal cohort of 7081 young people accessing early intervention care, between 2008 and 2020. Outcomes were mortality rates and age-standardised mortality ratios (SMR). Cox regression was used to identify predictors of all-cause mortality and deaths due to suicide or accident.

RESULTS

There were 60 deaths (male 63.3%) during the study period, 25 (42%) due to suicide, 19 (32%) from accident or injury and eight (13.3%) where cause was under investigation. All-cause SMR was 2.0 (95% CI 1.6-2.6) but higher for males (5.3, 95% CI 3.8-7.0). The mortality rate from suicide and accidental deaths was 101.56 per 100 000 person-years. Poisoning, whether intentional or accidental, was the single greatest primary cause of death (26.7%). Prior emergency department presentation for poisoning (hazard ratio (HR) 4.40, 95% CI 2.13-9.09) and psychiatric admission (HR 4.01, 95% CI 1.81-8.88) were the strongest predictors of mortality.

CONCLUSION

Premature mortality in young people accessing early intervention mental health services is greatly increased relative to population. Prior health service use and method of self-harm are useful predictors of future mortality. Enhanced care pathways following emergency department presentations should not be limited to those reporting suicidal ideation or intent.

Association between psychotropic prescriptions and the total amount of psychotropics ingested during an intentional overdose: A single-center retrospective study

Aim

To investigate the association between psychotropic prescriptions and the total amount of psychotropics ingested during a subsequent intentional overdose and to examine factors related to the number of psychotropic prescriptions.

Methods

The initial sample comprised 69 patients who were admitted to the emergency department of a general hospital in Japan following an intentional overdose via psychotropic medications. We performed retrospective hierarchical multiple regression analysis with the total amount of psychotropics ingested at the overdose as a dependent variable and factors related to deliberate self‐harm or overdose identified in previous studies as independent variables. We compared two models, one that did not (Step 1) and one that did (Step 2) include the number of different prescribed psychotropic medications as an independent variable in the analysis.

Results

Forty‐seven patients were eligible for the analysis. The number of different prescribed psychotropic medications was associated with the total amount of psychotropics ingested at the overdose in Step 2 (β = 0.40, P = .01). There was a trend toward an association between the past number of deliberate self‐harm events and the total amount of psychotropics ingested at the overdose in Step 1 (β = 0.30, P = .05), but this trend was weakened in Step 2 (β = 0.15, P = .33).

Conclusion

The number of different prescribed psychotropics appeared to influence the risk of subsequent intentional overdose through increasing the total amount of psychotropics ingested. Cumulative psychotropic prescriptions, particularly those delivered after deliberate self‐harm, might be indirectly related to this risk.

A Comparison of Presentations with Self-Harm to Hospital in Lithuania and Ireland

Suicide is a serious problem globally, especially in Europe, with suicide rates varying between different countries. Self-harm is a known risk factor for dying by suicide and represents an opportunity to intervene in order to treat any associated mental illness and reduce risk. This study aimed to compare the characteristics of people presenting to hospital with self-harm at two clinical sites: Galway, Ireland and Kaunas, Lithuania. Data were obtained from the services’ database and anonymised for analysis. Over a 5-month period, 89 patients presented with self-harm at the Lithuanian site and 224 patients presented with self-harm at the Irish site. This study found significant differences in presentation, diagnosis and treatment between the two sites. All patients at the Lithuanian site were admitted to psychiatry, compared to 22% of patients at the Irish site (p < 0.001). In Lithuania, the main clinical diagnoses were adjustment disorder (37.1%) and major depression (20.2%), compared to substance misuse being the main clinical diagnosis (33.8%) in Ireland (p < 0.001). There were significant differences in the prescription of psychotropic medications (which were three times more commonly prescribed at the Lithuanian site) after controlling for age, gender and psychiatric history (p < 0.001). Further research is required to understand the cultural context behind and further association between hospitalisation and future death by suicide.

A drink before suicide: analysis of the Queensland Suicide Register in Australia

AIMS

Previous studies analysing blood alcohol concentration (BAC) at the time of suicide have primarily focused on sociodemographic factors. Limited research has focused on psychosocial factors and co-ingestion of other substances to understand the mechanisms of how alcohol contributes to death by suicide. The aim was to examine time trends, psychosocial factors related to acute alcohol use and co-ingestion of alcohol and other substances before suicide.

METHODS

The Queensland Suicide Register in 2004-2015 was utilised and analysed in 2019. The cut-off point for positive BAC was set at ⩾0.05 g/dl. Substances were categorised as medicines, illegal drugs and other. Medicines were coded by the Anatomical Therapeutic Chemical (ATC) classification system. Joinpoint regression, univariate odds ratios, age and sex-adjusted odds ratios and Forward Stepwise logistic regression were performed.

RESULTS

BAC information was available for 6744 suicides, 92% of all cases in 2004-2015. The final model showed that independent factors distinguishing BAC+ from BAC- were: age group 25-44 years, Australian Indigenous background, being separated or divorced, hanging, diagnosis of substance use, lifetime suicidal ideation, relationship and interpersonal conflict, not having psychotic and other psychiatric disorder, and no nervous system drugs or any other substances in blood at the time of suicide.

CONCLUSIONS

Our findings suggest that people who die by suicide while under the influence of alcohol are more likely to be under acute stress (e.g. separation) and not have earlier psychiatric conditions, except substance use. This highlights the importance of more strict alcohol policies, but also the need to improve substance use treatment.
