Non-suicidal deaths following hospital-treated self-poisoning

Premature Death Among Primary Care Patients With a History of Self-Harm

PURPOSE

Self-harm is a public health problem that requires a better understanding of mortality risk. We undertook a study to examine premature mortality in a nationally representative cohort of primary care patients who had harmed themselves.

METHODS

During 2001-2013, a total of 385 general practices in England contributed data to the Clinical Practice Research Datalink with linkage to Office for National Statistics mortality records. We identified 30,017 persons aged 15 to 64 years with a recorded episode of self-harm. We estimated the relative risks of all-cause and cause-specific natural and unnatural mortality using a comparison cohort of 600,258 individuals matched on age, sex, and general practice.

RESULTS

We found an elevated risk of dying prematurely from any cause among the self-harm cohort, especially in the first year of follow-up (adjusted hazard ratio for that year, 3.6; 95% CI, 3.1-4.2). In particular, suicide risk was especially high during the first year (adjusted hazard ratio, 54.4; 95% CI, 34.3-86.3); although it declined sharply, it remained much higher than that in the comparison cohort. Large elevations of risk throughout the follow-up period were also observed for accidental, alcohol-related, and drug poisoning deaths. At 10 years of follow-up, cumulative incidence values were 6.5% (95% CI, 6.0%-7.1%) for all-cause mortality and 1.3% (95% CI, 1.2%-1.5%) for suicide.

CONCLUSIONS

Primary care patients who have harmed themselves are at greatly increased risk of dying prematurely by natural and unnatural causes, and especially within a year of a first episode. These individuals visit clinicians at a relatively high frequency, which presents a clear opportunity for preventive action. Primary care patients with myriad comorbidities, including self-harming behavior, mental disorder, addictions, and physical illnesses, will require concerted, multipronged, multidisciplinary collaborative care approaches.

MIDSHIPS: multicentre intervention designed for self-harm using interpersonal problem-solving: protocol for a randomised controlled feasibility study

BACKGROUND

Around 150,000 people each year attend hospitals in England due to self-harm, many of them more than once. Over 5,000 people die by suicide each year in the UK, a quarter of them having attended hospital in the previous year because of self-harm. Self-harm is a major identifiable risk factor for suicide. People receive variable care at hospital; many are not assessed for their psychological needs and little psychological therapy is offered. Despite its frequent occurrence, we have no clear research evidence about how to reduce the repetition of self-harm. Some people who have self-harmed show less active ways of solving problems, and brief problem-solving therapies are considered the most promising psychological treatments.

METHODS/DESIGN

This is a pragmatic, individually randomised, controlled, feasibility study comparing interpersonal problem-solving therapy plus treatment-as-usual with treatment-as-usual alone, for adults attending a general hospital following self-harm. A total of 60 participants will be randomised equally between the treatment arms, which will be balanced with respect to the type of most recent self-harm event, number of previous self-harm events, gender and age. Feasibility objectives are as follows: a) To establish and field test procedures for implementing the problem-solving intervention; b) To determine the feasibility and best method of participant recruitment and follow up; c) To assess therapeutic delivery; d) To assess the feasibility of obtaining the definitive trial's primary and secondary outcomes; e) To assess the perceived burden and acceptability of obtaining the trial's self-reported outcome data; f) To inform the sample size calculation for the definitive trial.

DISCUSSION

The results of this feasibility study will be used to determine the appropriateness of proceeding to a definitive trial and will allow us to design an achievable trial of interpersonal problem-solving therapy for adults who self-harm.

Managing deliberate self-harm in young people: an evaluation of a training program developed for school welfare staff using a longitudinal research design

BACKGROUND

Although deliberate self-harm is prevalent among young people, many who engage in deliberate self-harm receive sub-optimal care. Although schools are a well placed setting to support young people who engage in self-harm there are no specific training packages designed to assist school welfare staff to support these young people.The current study aimed to design, deliver and evaluate a training course specifically for school staff.

METHODS

The study employed a longitudinal design. Two hundred and thirteen people participated in the training and evaluation. A questionnaire was administered at baseline, immediately after the training and at 6-month follow-up in order to determine if the training led to improvements in confidence when working with young people who self-harm, perceived skill, knowledge of, and attitudes towards people who self harm.

RESULTS

Prior to the course, the majority of participants demonstrated relatively high levels of confidence, perceived skill and knowledge of self-harm and endorsed relatively positive attitudes towards people who engage in self-harm. Despite this, significant improvements were observed in terms of increased confidence, increased perceptions of skill along with increased knowledge of deliberate self-harm. These improvements were sustained over the follow-up period.

CONCLUSION

The results demonstrated that the provision of specifically designed training can help school welfare staff to feel better equipped to support young people who are engaging in deliberate self-harm.

Injury risk in young psychiatric outpatients: an 11-year follow-up of 302 adolescents

BACKGROUND

Studies investigating the association between injuries and mental health have mainly focused on mental health sequelae of injuries. The aim of this prospective cohort study was to assess the incidence and risk factors of physical injury hospitalisation and poisoning hospitalisation among adolescent psychiatric outpatients.

SUBJECTS AND METHODS

Data on 302 consecutively referred Finnish psychiatric outpatients aged 12-22 years (mean 16) were collected at treatment entry. The end-point of the average 11-year follow-up was death or end of follow-up on 31 December 2005. The main outcome variables were physical injury hospitalisation and poisoning hospitalisation.

RESULTS

Altogether 111 physical injury hospitalisations occurred in 65 (22% of all) persons during follow-up, incidence being 27.9 (95% CI: 22.7-33.1) per 1,000 person-years. Poisoning hospitalisation occurred in 22 (7.3%) persons, altogether 50 times, incidence being 12.6 (95% CI: 9.1-16.0). Seven injury-related deaths occurred, incidence being 1.8 (95% CI: 0.5-3.1) per 1,000 person-years. The most common physical injury types were fractures (40%), followed by distortions (10%) and wounds (10%), while poisoning for drugs accounted for 72% of the poisonings. Previous inpatient care, psychotropic medication, suicidality, and major depression were associated with poisoning hospitalisation during the follow-up while only gender was associated with physical injury hospitalisation.

CONCLUSION

Injuries cause significant morbidity among psychiatric outpatients, but only poisonings seem to be related with suicidality in Finnish adolescent psychiatric outpatients. The high frequency of injuries seems to justify clinicians' attention to these aspects when assessing the need for care among young people.

Age-sex differences in medicinal self-poisonings: a population-based study of deliberate intent and medical severity

BACKGROUND

Deliberate self-harm (DSH) is related to suicide and DSH repetition is common. DSH hospital presentations are often self-poisonings with medicinal agents. While older age and male sex are known risk factors for suicide, it is unclear how these factors are related to the nature and severity of medicinal self-poisoning (SP). Such knowledge can guide prevention strategies emphasizing detecting and treating mental illness and controlling access to means.

METHODS

Medicinal SP presentations by 18,383 residents of Ontario, Canada, aged 12 years and older, who presented to a hospital emergency department in that province between April 1, 2001-March 31, 2002 were characterized by the agents taken, identification of deliberate intent and medical severity.

RESULTS

We found distinct age-sex differences in the nature and severity of medicinal SP. In youths, aged 12-17, about 40% of presentations involved analgesics, typically not prescribed and most often the acetaminophen agent-group. Females aged 12-64 were identified as deliberate more often than their male counterparts and this pattern occurred in most agent-groups, even among those who took antidepressants. The acetaminophen agent-group was most consistently associated with medical severity and this effect was strongest among female youths. Although medicinal SP was less frequent in the elderly, these presentations tended to be more medically serious and less often identified deliberate.

CONCLUSIONS

The high proportion of medicinal SP in youths involving agents typically not prescribed and the medical severity of the acetaminophen agent-group underscore how prevention strategies must extend beyond controlling access to antidepressants. Despite a higher risk for suicide, males and the elderly may not have their deliberate intent detected and therefore, may not receive appropriate treatment. The emergency department can serve as important link to mental health care and usage patterns can provide feedback about the need for system-level enhancements and DSH surveillance.
