The hospital management of fatal self-poisoning in industrialized countries: an opportunity for suicide prevention?

Over-the-counter analgesics use is associated with pain and psychological distress among adolescents: a mixed effects approach in cross-sectional survey data from Norway

BACKGROUND

Over-the-counter analgesics (OTCA) such as Paracetamol and Ibuprofen are frequently used by adolescents, and the route of administration and access at home allows unsupervised use. Psychological distress and pain occur simultaneously and are more common among females than among males. There is a dynamic interplay between on-label pain indications and psychological distress, and frequent OTCA use or misuse can exacerbate symptoms. No studies have to date provided an overview of frequent OTCA use in a larger population-based study. The current study used survey data to explore associations between and the relative predictive value of on-label pain indication and measures of psychological distress, together with sex differences for weekly OTCA use.

METHODS

This study included 349,528 adolescents aged 13-19. The data was collected annually between January 2014 and December 2018 as part of the Norwegian Young Data survey. Performance analysis was conducted to explore the relative roles and associations between on-label pain indication and psychological distress in weekly OTCA use. A mixed-effects logistic regression model was used to explore the unique contributions from four domains of on-label pain indication and psychological distress as measured by a combined measure of anxiety and depression (HSCL-10) and peer-bullying involvement as victims or bullies.

RESULTS

Thirty percent of females and 13 % of males use OTCA weekly. Headache is the strongest on-label pain predictor of weekly OTCA use, followed by abdominal pain. Depression and anxiety are the strongest psychological predictor of weekly OTCA use, and higher symptom levels and being female increase the strength of this association. Anxiety and depression also predict weekly OTCA use after controlling for physiological pain.

CONCLUSIONS

Sex, pain and anxiety and depression are inter-correlated and strong predictors of frequent OTCA use. Frequent OTCA use in the context of psychological distress may be a form of self-medication that can exacerbate symptoms and decrease psychosocial function. Longitudinal studies that explore causal trajectories between frequent on-label OTCA use and psychological distress are required. OTCA use among adolescents, and particularly among females, with anxiety and depression should be administered with caution and closely monitored.

The Effect of Active Treatment and Visit Compared to Conventional Treatment, on Preventing Recurrent Suicidal Attempts: A Randomized Controlled Clinical Trial

BACKGROUND

Suicide is a major problem, and its prevention is a global priority. In many cases, suicide attempter attempts to do it again after the rescue. In current study we aimed to compare active visit and treatment of patients in a periodic manner with treatment as usual, in the prevention of recurrent suicidal attempts.

MATERIALS AND METHODS

This study was a randomized controlled clinical trial which was conducted in Isfahan Noor Hospital's Emergency Center on 60 patients in 2013-2014. The samples were selected using simple random sampling and they were assigned into two groups: The conventional treatment group (treatment as usual) (30 patients), and visit and active treatment (30 patients). In the intervention group, there were ten follow-ups by a face-to-face visit over 12 months, and six follow-ups by phone call in control group. Through the completion of the initial and follow-up questionnaire evaluation was performed. The data were analyzed using Cochran test, and repeated measure (ANOVA).

RESULTS

During the 12-month follow-up visit and active treatment, significant difference in reducing suicidal thoughts (P = 0.003) was observed and an increase in the life expectancy (P = 0.001), interest and motivation in life (P = 0.001) was found in the intervention group, and also nonsignificant reduction was found in the rate of suicidal attempts.

CONCLUSION

Visit and active treatment is useful in suicide attempters and it can helps in preventing recurrent suicide attempt as a preventive program by increasing hope and reducing suicidal thoughts.

The efficacy of telephonic follow up in prevention of suicidal reattempt in patients with suicide attempt history

Background:

prevention of suicide is one of priority world health. Suicide is one of the preventable causes of death. The aim of this study is evaluation of telephone follow up on suicide reattempt.

Materials and Methods:

This randomized controlled clinical trial is a prospective study which has been done in Noor Hospital of Isfahan-Iran, at 2010. 139 patients who have suicide attempt history divided in one of two groups, randomly, 70 patients in” treatment as usual (TAU)” and 69 patients in “brief interventional control (BIC). Seven telephone contact with BIC group patients have been done “during six months” and two questionnaires have been filled in each session. The data has been analyzed by descriptive and Chi-square test, under SPSS.

Results:

No significant differences of suicide reattempt has been found between two groups (P = 0.18), but significant reduction in frequency of suicidal thoughts (P = 0.007) and increase in hope at life (P = 0.001) was shown in intervention group.

Conclusion:

Telephones follow up in patients with suicide history decrease suicidal thought frequency” and increase hope in life, significantly.

Fatal poisonings in Finland during the years 2004-2009

Fatal alcohol and drug poisonings in Finland during the years 2004-2009 were studied. Cases were divided into those that occurred outside the hospitals (the majority of cases) and those that occurred within the hospitals (the minority of cases). Differences and similarities between the two groups were analysed. The postmortem toxicological investigation of all sudden and unexpected deaths in Finland is centralised at the Department of Forensic Medicine, University of Helsinki. We examined each fatal poisoning separately and verified the cause and place of death as well as the age and sex of the deceased. Fatal poisonings, including suicides, have remained unchanged for many years from the same high level, that is, about 1200 cases annually (22/100,000 inhabitants). The number of patients dying in hospitals due to poisoning has also remained stable (55-70 patients/year). However, the toxic agents involved in such poisonings have changed and deaths due to opioids are now being more numerous. The number of fatal unintentional drug poisonings rose significantly from 191 to 341 (3-6/100,000 inhabitants, p < 0.001) during the study years, and the difference between poisonings caused by drugs or alcohol also changed significantly (p < 0.001). Diminishing substantially, the number of all fatal poisonings will be challenging because of the high percentage of suicides. However, a reduction in unintentional drug overdoses, which are presently on the rise, should be possible.

Self-poisoning suicide deaths in England: could improved medical management contribute to suicide prevention?

BACKGROUND

Suicide by self-poisoning is a major cause of death worldwide. Few studies have investigated the medical management of fatal self-poisoning.

AIM

To describe the characteristics and management of a national sample of individuals who died by intentional self-poisoning in hospital and assess the quality of care that they received.

DESIGN

National population-based descriptive study and confidential inquiry.

METHODS

Adults (aged ≥ 16 years) who had died by self-poisoning in English hospitals in 2005 and received a coroner's verdict of suicide or undetermined death at inquest were included. Socio-demographic and clinical data were collected through detailed questionnaires sent to clinicians at the treating hospitals. A panel of three expert assessors rated each case with respect to quality of care and likely contribution to the fatal outcome.

RESULTS

We obtained information on 121 cases (response rate for questionnaires 77%). Expert assessors rated 41/104 cases [39% (95% CI 30-49%)] as having received inadequate care; in the majority (38/41-93%) of these, this poor care was felt to have potentially contributed to the patient's death. The most common reason for a rating of inadequate care was poor airway management (recorded in over half of inadequate care cases). In three cases, the receipt of inadequate care was associated with the presence of some form of advance directive.

CONCLUSION

In as many as 39% of in-hospital self-poisoning fatalities, the care received may be in some way sub-optimal. The challenge for clinical services is to ensure that optimal management strategies are implemented in practice.

Suicidal intention, psychosocial factors and referral to further treatment: a one-year cross-sectional study of self-poisoning

BACKGROUND

Patients treated for self-poisoning have an increased risk of death, both by natural and unnatural causes. The follow-up of these patients is therefore of great importance. The aim of this study was to explore the differences in psychosocial factors and referrals to follow-up among self-poisoning patients according to their evaluated intention.

METHODS

A cross-sectional multicenter study of all 908 admissions to hospital because of self-poisoning in Oslo during one year was completed. Fifty-four percent were females, and the median age was 36 years. The patients were grouped according to evaluated intention: suicide attempts (moderate to high suicide intent), appeals (low suicide intent) and substance-use related poisonings. Multinomial regression analyses compared patients based on their evaluated intention; suicide attempts were used as the reference.

RESULTS

Of all self-poisoning incidents, 37% were suicide attempts, 26% were appeals and 38% were related to substance use. Fifty-five percent of the patients reported previous suicide attempts, 58% reported previous or current psychiatric treatment and 32% reported daily substance use. Overall, patients treated for self-poisoning showed a lack of social integration. Only 33% were employed, 34% were married or cohabiting and 53% were living alone. Those in the suicide attempt and appeal groups had more previous suicide attempts and reported more psychiatric treatment than those with poisoning related to substance use. One third of all patients with substance use-related poisoning reported previous suicide attempts, and one third of suicide attempt patients reported daily substance use. Gender distribution was the only statistically significant difference between the appeal patients and suicide attempt patients. Almost one in every five patients was discharged without any plans for follow-up: 36% of patients with substance use-related poisoning and 5% of suicide attempt patients. Thirty-eight percent of all suicide attempt patients were admitted to a psychiatric ward. Only 10% of patients with substance use-related poisoning were referred to substance abuse treatment.

CONCLUSIONS

All patients had several risk factors for suicidal behavior. There were only minor differences between suicide attempt patients and appeal patients. If the self-poisoning was evaluated as related to substance use, the patient was often discharged without plans for follow-up.

The impact of rural residence on medically serious medicinal self-poisonings

OBJECTIVE

Suicide rates are often high in rural areas. Despite the strong association between deliberate self-harm (DSH) and suicide, few have studied rural residence and DSH. Self-poisonings dominate DSH hospital presentations. We investigate a previously reported association between rural residence and medical severity (defined as a subsequent medical/surgical inpatient stay) among emergency department presentations for medicinal self-poisoning (SP) to determine whether differences in agents taken, mental health service use or hospital-level resources explain the relationship.

METHOD

A cohort of n=16,294 12-64-year olds presenting with SP to hospital emergency departments in Ontario, Canada, in 2001/2002 was linked to their service records over time.

RESULTS

The rural-medical severity association was best explained by differences in hospital resources; presenting to hospitals providing inpatient psychiatric services appeared to reduce medical/surgical inpatient stays in favor of psychiatric ones. Among those with a recent psychiatric admission, more intensive ambulatory psychiatric contact may be protective of a psychiatric inpatient stay subsequent to the SP presentation. Compared to nonrural residents, deliberate intent was identified less often in rural residents, particularly males.

CONCLUSIONS

The rural-medical severity association was best explained by disparities in the delivery systems serving rural and nonrural residents, important to rural suicide prevention efforts.

Trends in US emergency department visits for suicide attempts, 1992-2001

This article describes trends in suicide attempt visits to emergency departments in the United States (US). Data were obtained from the National Hospital Ambulatory Medical Care Survey using mental-health-related ICD-9-CM, E and V codes, and mental-health reasons for visit. From 1992 to 2001, mental-health-related visits increased 27.5% from 17.1 to 23.6 per 1000 (p < .001). Emergency Department (ED) visits for suicide attempt and self injury increased by 47%, from 0.8 to 1.5 visits per 1000 US population (p(trend) = .04). Suicide-attempt-related visits increased significantly among males over the decade and among females from 1992/1993 to 1998/1999. Suicide attempt visits increased in non-Hispanic whites, patients under 15 years or those between 50-69 years of age, and the privately insured. Hospitalization rates for suicide attempt-related ED visits declined from 49% to 32% between 1992 and 2001 (p = .04). Suicide attempt-related visits increased significantly in urban areas, but in rural areas suicide attempt visits stayed relatively constant, despite significant rural decreases in mental-health related visits overall. Ten-year regional increases in suicide attempt-related visits were significant for the West and Northeast only. US emergency departments have witnessed increasing rates of ED visits for suicide attempts during a decade of significant reciprocal decreases in postattempt hospitalization. Emergency departments are increasingly important sites for identifying, assessing and treating individuals with suicidal behavior.

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.

The effect of yogurt on acetaminophen absorption by activated charcoal and burnt toast

Although acetaminophen overdose can be treated with N-acetylcysteine, activated charcoal is useful in preventing absorption of acetaminophen from the gut. Mixing activated charcoal with yogurt may make the dose more palatable. We investigated effects of yogurt on absorption of acetaminophen by burnt toast or activated charcoal in intestinal fluid using an in vitro model. The aliquots of phosphate buffer saline (PBS) were supplemented with high concentrations of acetaminophen after adjusting the pH to 7.2 (to mimic intestinal fluid). Then specimens were treated with various dosages (15 mg/mL, 25 mg/mL, or 50 mg/mL) of activated charcoal or burnt toast. A small amount of fluid was withdrawn at 0, 5, 10, 20, and 30 min and acetaminophen concentrations were measured by the fluorescence polarization immunoassay (FPIA). We also treated other aliquots of PBS buffer containing acetaminophen with activated charcoal and yogurt or burnt toast and yogurt. Then small aliquots were withdrawn at specific time intervals to determine concentrations of acetaminophen. Activated charcoal was very effective in removing acetaminophen from intestinal fluids and the presence of yogurt insignificantly affected such absorptions. In contrast, burnt toast had a modest effect on removing acetaminophen from fluids but yogurt significantly increased the capability of burnt toast to absorb acetaminophen. However, the activated charcoal/yogurt combination is more effective than the burnt toast/yogurt combination for absorbing acetaminophen.
