Deliberate self-poisoning in an Irish county hospital

Adolescents with suicidal behaviour: attendance at A&E and six month follow-up

Objectives: To review the clinical presentation, and Accident and Emergency Department clinical response to 14-20 year olds in suicidal crisis in inner city Dublin and to carry out a six month follow up of these young people.

Method: A retrospective review of the case notes of all 14-20 year olds who had attended the Mater Hospital A&E department between June 2001 and May 2002 with suicidal behaviour or ideation was carried out in order to establish socio-demographic information, type of suicidal or self-harming behaviour, intervention in the A&E department, and discharge plan. Active outreach attempts were made to trace, contact and interview these young peoples at least six months after the initial presentation. Quantitative measures of psychological functioning at follow-up included the General Health Questionnaire, The Beck Depression Inventory and The Scale for Suicidal Ideation. A qualitative interview covered their recall of the reasons for their deliberate self harm, their view of their current psychological functioning and personal relationships, reported repetition of deliberate self harm, and their views of what type of services would be useful for young people with suicidal ideation or behaviour.

Results: A total of 89 young people aged 14-20 years (male: female ratio = 2:3) presented to the Mater A&E department between June 2001 and May 2002 with deliberate self-harm, deliberate self-poisoning and/or suicidal ideation, and accounted for 108 presentations. They showed high levels of psychosocial disadvantage. Almost half had a history of previous contact with mental health services, while the same proportion had a history of previous deliberate self-harm. Drug overdose using paracetamol was the most common method used. Psychiatric assessment was documented in 66% of cases, and documented follow up recommendations were made in 60% of cases. Two thirds of the 89 young people who formed the study population were traced. Half of those contacted agreed to be interviewed and half refused. The majority of those interviewed described themselves as functioning better psychologically than at the time of the index attendance at the A&E department The quantitative measures supported this. One third of those interviewed reported repeated deliberate self-harm since their index attendance, for which most did not seek medical intervention. Many of the young people had clear views about the importance of talking to someone when in crisis. They described a service, which was informal, accessible on a 24-hour basis, and staffed by people with experience of mental health, alcohol and drug related disorders.

Conclusions: This is a particularly vulnerable group of patients from a socio-demographic and mental health perspective. Their attendance at the A&E department provides a unique opportunity for an in-depth psychosocial assessment, which should be recorded in a systematic way to assist clinical audit, facilitate strategic mental health planning and may confer some therapeutic clinical benefit to at risk young people. An easily accessible, active DSH team specifically tailored for young people in the A&E department could provide assessment and short-term follow-up. This is the approach recommended by young people in suicidal crisis, whose views need to be heard.

A retrospective analysis of acute poisoning during pregnancy

OBJECTIVE

The aim of this study is to investigate and analyse pregnant women who were admitted to our emergency service due to acute poisoning.

MATERIAL AND METHODS

All cases were retrospectively collected from our computer records and emergency record book between 01.01.2006 and 01.01.2010; the registration data on age, gravidity, gestational week, whether the poisoning was deliberate or accidental, causative agent, admission time, treatment results and mortality outcome were collected and analyzed.

RESULTS

Eighty eight women admitted with acute poisoning were known to be pregnant and the poisoning was accidental in 23% of the cases, while 77% were suicidal intoxications. 74% of patients were in the 21-34 age group. Accidental intoxications were due to carbon monoxide, foods and cleaning products. 75.4% of the suicidal poisonings were caused by medical drugs, with analgesics, multiple drugs and psychiatric drugs being the top culprits and accounted for 53%, 31% and 16% of drug poisonings respectively. In terms of gestational week, 47.4% of suicidal poisonings were within the first trimester and the relationship between suicidal attempt and gestational week was found to be statistically significant (p<0.015). However, the relationship between gravidity and the rate of suicidal attempts was not statistically significant (p=0.214). All patients were followed up and treated in the emergency service and no mortality was observed in the study.

CONCLUSION

Most cases of acute poisonings during pregnancy were suicidal. Pregnant women attempted suicide mostly within the first trimester of gestation. The most common agents used for suicidal attempt were medical drugs.

Effect of acute alcohol use on the lethality of suicide attempts in patients with mood disorders

Acute alcohol use is an important risk factor for attempted and completed suicide. We evaluated the effect of acute alcohol intake on the lethality of suicide attempts to test the hypothesis that acute alcohol intoxication is associated with more lethal suicide attempts. This retrospective study included 317 suicide attempters enrolled in mood disorders protocols. Demographic and clinical parameters were assessed. The use of alcohol at the time of the most lethal suicide attempt was determined. On the basis of their responses participants were classified into three groups: participants who reported "Enough alcohol intake to impair judgment, reality testing and diminish responsibility" or "Intentional intake of alcohol in order to facilitate implementation of attempt" were included in the group "Alcohol" (A); participants who reported "Some alcohol intake prior to but not related to attempt, reportedly not enough to impair judgment, reality testing" were included in the group "Some Alcohol" (SA); and participants who reported "No alcohol intake immediately prior to attempt" were included in the group "No Alcohol" (NA). Lethality of the most lethal suicide attempts was higher in the A group compared to the SA and NA groups. Prevalence of patients with alcohol use disorders was higher in the A group compared to the SA and NA groups. SA participants reported more reasons for living and lower suicide intent scores at the time of their most lethal suicide attempt compared to the A and NA groups. Acute alcohol use increases the lethality of suicide attempts in individuals with mood disorders.

Renal and liver transplantation for toxin-induced organ failure

OBJECTIVE

Determine the number and outcome of renal (January 1987-June 2001, inclusive) and liver transplants (January 1993-June 2001) performed in Ireland for drug or toxin-induced organ failure and identify the toxins involved.

METHODS

Retrospective review of national transplant coordinators' records and patient charts.

RESULTS

Fourteen patients received renal transplants for nephropathy secondary to drugs or toxins. In 12 of these cases, renal failure was attributed to chronic toxicity, principally cyclosporin A therapy (seven cases). One-year patient and graft survival were 100%. Twenty-nine liver transplants were for toxin-induced organ failure, and 20 of these were for chronic ethanol induced liver disease. One-year patient and graft survival rates were 77% and 73%, respectively.

CONCLUSIONS

Kidney and liver transplants were needed more often because of chronic toxicity than acute poisoning. Both groups had good outcomes at one year post-transplantation.

General characteristics of hospitalized patients after deliberate self-poisoning and risk factors for intensive care admission

BACKGROUND

Deliberate self-poisoning (DSP) is recognized as a major health problem worldwide with significant morbidity. After DSP, a substantial number of patients require intensive care unit (ICU) care, but little is known about how these patients differ from patients admitted to a general medical ward.

METHODS

From January 2001 to December 2002, all adult patients admitted to Soroka University Hospital after DSP were identified by ICD-9 coded diagnoses. Demographic data, previous psychiatric illness, laboratory tests, medication used in the DSP, presenting syndromes, treatment, and time elapsed after ingestion until emergency department presentation were obtained retrospectively from the patients' charts.

RESULTS

Out of a total of 217 patients, 34 (15.7%) were admitted to the ICU. Their mean age was 35.9 years and 65.4% of the patients were female. In multivariate analysis, the risk factors for ICU admission were suicide attempt with an antihypertensive medication (OR=12.2, 95% CI 2.3-65.8), coma on presentation (OR=15.8, 95% CI 4.9-50.7), and arrival at the emergency department less than 2 h after ingestion as compared to arrival after 2 h (OR=8.4, 95% CI 2.6-26.7). Previous psychiatric disease had no impact on ICU admission, and a recurrent attempt was protective of ICU admission.

CONCLUSIONS

We have shown that ingestion of antihypertensive medication, coma upon presentation, and emergency department admission less than 2 h after ingestion are predictive of ICU admission after a deliberate overdose with medication. These variables may help emergency department physicians to identify high-risk patients more quickly and, thereby, to improve patient care.

THE ASSOCIATION BETWEEN ALCOHOL MISUSE AND SUICIDAL BEHAVIOUR

AIMS

Despite recent small reductions in overall suicide rates, rates among those aged 25-44 have remained high. The aim of this paper was to examine the evidence for a link between alcohol misuse/consumption and suicidal behaviour, explore the reasons for this association, and consider the implications for reducing rates of suicidal behaviour.

METHODS

A medline search was performed to find relevant research evidence.

RESULTS

There is evidence to suggest alcohol misuse predisposes to suicidal behaviour through its depressogenic effects and promotion of adverse life events, and both behaviours may share a common genetic predisposition. Acute alcohol use can also precipitate suicidal behaviours through induction of negative affect and impairment of problem-solving skills, as well as aggravation of impulsive personality traits, possibly through effects on serotonergic neurotransmission.

CONCLUSIONS

Effective interventions for problem drinking may help reduce suicide rates. At a public health level, reducing overall alcohol consumption may be beneficial, and the measures shown to be most effective in this regard are those that aim to restrict availability of alcohol.

Tolerability of Paracetamol

The excellent tolerability of therapeutic doses of paracetamol (acetaminophen) is a major factor in the very wide use of the drug. The major problem in the use of paracetamol is its hepatotoxicity after an overdose. Hepatotoxicity has also been reported after therapeutic doses, but critical analysis indicates that most patients with alleged toxicity from therapeutic doses have taken overdoses. Importantly, prospective studies indicate that therapeutic doses of paracetamol are an unlikely cause of hepatotoxicity in patients who ingest moderate to large amounts of alcohol. Controlled clinical trials have found that paracetamol is very well tolerated by the gastrointestinal tract. While variable results have been found in case control studies, most studies have shown no change or a small increase in the relative risk of perforations, ulcer or bleeding in the upper gastrointestinal tract. However, associations between the use of paracetamol and gastrointestinal toxicity, as well as with chronic renal disease and asthma, are very likely to reflect biases in some case control studies. In particular, such biases may be caused by the perceived high tolerability of paracetamol in these diseases. The consequent use of paracetamol in these diseases states then leads to an apparent association between paracetamol and the disease. Despite metabolism of paracetamol to reactive compounds, hypersensitivity reactions are rare, although urticaria occurs in occasional patients. Paracetamol appears to be well tolerated during pregnancy although prospective studies are required.

A study of suicides in Kildare, 1995–2002

This paper focuses on 109 cases of suicide that occurred in Kildare from 1995 to 2002. These statistics were obtained by examining the records of the Kildare County Coroner. There is no central national location for the records of the 48 coroner jurisdictions in Ireland and all coroners are required by law to retain the files on each inquest indefinitely. However, the actual record of verdict given at inquest is not the one used for determining the suicide rate in the country. This is achieved by the Central Statistics Office (CSO) Form 104, which asks for the investigating police officer to give his or her opinion as to the cause of death. This results in discrepancies between what the coroner records and what the official suicide rate is presumed to be. These figures are further influenced by some coroners choosing to return a verdict "death in accordance with the medical evidence" as opposed to a verdict of suicide. The files were also examined to find the high-risk groups or those groups which have a tendency towards suicide. Over 84% of suicides were male and 32 men were between the ages of 20 and 30. It is suggested that the standardisation of recording verdicts of suicide be implemented as soon as possible as the current situation leads to variances between coroner's records and those kept by the CSO.

Acute alcohol use and suicidal behavior: a review of the literature

BACKGROUND

Both acute and chronic use of alcohol are associated with suicidal behavior. However, the differing relationship of each component of alcohol use and possible causal mechanisms remain unclear.

METHODS

This article reviews and summarizes associations between acute alcohol consumption (with and without intoxication) and suicidal behavior (both completed suicide and suicide attempts) among adults 19 years and older, as presented in literature published between 1991 and 2001. Possible mechanisms and methodologic challenges for evaluating the association are also discussed. An application of a research design (the case-crossover study) that has the potential for addressing the effects of acute alcohol use over and above usual or chronic use is presented.

RESULTS

The majority of articles reviewed were restricted to descriptive studies that documented the prevalence of suicide completers or attempters who tested positive for alcohol use. A wide range of alcohol-positive cases were found for both completed suicide (10-69%) and suicide attempts (10-73%). Common methodologic limitations included the lack of control groups (for evaluating risk conferred by alcohol use), selection and ascertainment bias, and small sample sizes. The results of the case-crossover pilot study indicated substantially higher risk of suicide during or shortly after use of alcohol compared with alcohol-free periods.

CONCLUSIONS

Although there is a substantial literature of published studies on acute alcohol use and suicidal behavior, the majority of studies focus on completed suicide and report prevalence estimates. Findings from such studies are subject to several possible sources of bias and have not advanced our knowledge of mechanisms in the association between acute alcohol use and suicidal behavior. The case-crossover design may help to overcome some limitations of these studies and facilitate evaluation of associations and possible causal mechanisms by which acute alcohol use is linked to suicidal behavior.
