Hospitalizations for pediatric intoxication in Washington State, 1987-1997

Drug self-poisoning in adolescents: A report of 267 cases

Introduction

The current study aims at describing a sample of adolescents admitted to a tertiary referral pediatric hospital for drug self-poisoning and to identify variables that could explain and predict a higher severity of intoxication.

Methods

We retrospectively reviewed the cases of drug self-poisoning in adolescents admitted to the Bambino Gesù Children's Hospital between January 2014 and June 2022 requiring consultation by the local Pediatric Poison Control Center (PPCC). We reported the type and class of drug ingested and correlated the clinical characteristics of the patients with their Poison Severity Score.

Results

The data of 267 patients were reported. Most patients were female (85.8 %), with a median age of 15.8 years at presentation. Half of the patients were symptomatic at admission (44.2 %), and most had at least one psychiatric comorbidity (71.1 %). Most patients were hospitalized (79.6 %), 16.6 % of cases required antidote administration and a minority required intensive care. Most patients received a PSS score of 0 (59.6 %). The most frequently ingested drug was acetaminophen (28.1 %) followed by ibuprofen (10.1 %) and aripiprazole (10.1 %). Antipsychotics as a class were the most abused drugs (33.1 %). The correlation of clinical variables with the PSS showed that older and male patients were more prone to be severely intoxicated.

Conclusions

This single-center study identifies the most commonly ingested drugs in a large sample of adolescents with voluntary drug self-poisoning, also showing that older and male patients are more susceptible to severe intoxication.

Accidental poisoning in children: a single centre case series study in Bangladesh

BACKGROUND

Accidental poisoning is a leading cause of unintentional injuries among children in low-income and middle-income countries (LMICs). The overall aspect of this unintentional poisoning is poorly understood in Bangladesh. The objectives of this study were (1) to explore the socio-demographic factors and circumstantial context of accidental poisoning and (2) the prevalence of the type of substances causing it.

METHODS

A descriptive case series study was conducted from April 2019 to February 2020 at a tertiary level hospital of the capital city Dhaka in Bangladesh. Children under 10 years of age admitted to the hospital with accidental poisoning were enrolled in this study. Parents of hospitalised children were interviewed face-to-face using a structured questionnaire. Descriptive statistics were used for data analysis.

RESULTS

A total of 223 children were recruited in this study. Children between 2 and 5 years (60%), men (61%) and children with agility (65.5%) were among the prevalent victims. The majority of cases occurred (65%) in a nuclear family setting. Most mothers (85%) of these children were non-working and most incidents took place in parents' homes (~82%). Nearly 70% of the poisoning incidents took place in the presence of parents and over half of these occurred in the bedroom. Kerosene was the prevalent cause (33%) of accidental poisoning while insecticide/pesticide ranked second (26.5%) followed by medicines (17%) and household chemicals (12). In one-third (31.4%) of the cases, poisoning chemicals were stored in soft drink bottles while two-thirds (67.3%) of the cases were kept in containers other than original ones. Although over 80 parents somewhat knew that chemicals could be harmful to the children if ingested, most of them did not take the safety measures.

CONCLUSION

In this present study we found that preschool-aged children were more victims of accidental poisoning mostly by ingesting kerosene and a majority of the incidents took place in the bedroom while parents were present at home. Our study findings would serve as a baseline for designing future intervention studies and policies.

Acute medication poisoning causing hospital admissions in childhood: a 3-year prospective observational single-center study

Although the risks of medication poisoning in children are often reported, there is a lack of studies addressing this issue. The majority of papers deal with a wide range of xenobiotics poisoning and, in particular, alcohol intoxications. All hospital admissions during three years were prospectively recorded. Patients younger than 19 years of age admitted for acute drug intoxications were further evaluated. A total of 15,069 children were admitted. Of them, 55 were hospitalized for acute medication poisoning. The condition was more common in girls (72.7 % vs. 27.3 %, p<0.01). Toddlers were the largest patient group (36.4 %). Non-steroidal anti-inflammatory drugs (NSAIDs) were the most frequently used agents, with ibuprofen being the leading drug (20 % of all cases). The route of intoxication was almost exclusively oral. Solid drug forms were involved in 40 (72.7 %) cases. There was one fatal accidental poisoning. The highest occurrence of accidental drug intoxications was in the age group from one to three years. Attempted suicides were most frequent among adolescents. We are currently actively dealing with the issue. The cohort has been expanded to include a period of ten years and is being analyzed.

Nature and sources of poisoning in patients admitted to a referral hospital in Gaborone, Botswana; findings and implications

BACKGROUND

Intentional poisoning is becoming an important public health concern particularly among young women globally. Consequently, there is a need to analyze this further within countries to establish pertinent policies to reduce current incidence rates. This includes sub-Saharan African countries where there has been a scarcity of information. Consequently, we sought to establish the nature and sources of poisoning in patients admitted to a leading hospital in Botswana to help develop pertinent future policies for Botswana and surrounding countries.

METHODS

Retrospectively reviewing the medical records of all patients admitted to Princess Marina Hospital (PMH), which is a leading tertiary hospital in the capital city of Botswana, due to acute poisoning over a six-year period.

RESULTS

The records for 408 patients were reviewed. The majority of admissions (58%) were females, and the mean age of patients was 21(±14) years. Most poisoning cases (53%) were intentional. The 15-45 years age group was most likely to intentionally poison themselves compared to other age groups, with females four and half times more likely to intentionally poison themselves compared to males (AOR 4.53, 95% CI: 2.68-7.89, p < 0.001). Half of the patients were poisoned by medicines followed by household chemicals (22%), with females overall four times more likely to be poisoned by medicines compared to males. The medicine mostly ingested was paracetamol (30%). Failing relationships (57%) were the principal reason for intentional poisoning. Six patients died from poisoning representing a 1.5% mortality rate.

CONCLUSIONS

The findings suggest in-depth and urgent investigations on intentional poisoning are needed among young women across countries including sub-Saharan African countries to inform future policies on prevention strategies. Further, strategies for poisoning prevention should target social and family relationship problems. We will be following this up in the future.

Childhood Drug and Non-Drug Poisoning in Nigeria: An Economic Appraisal

Background:

The dearth of information on the economic cost of childhood poisoning in sub-Saharan Africa necessitated this study.

Objective:

This study has investigated the prevalence of childhood drug and non-drug poisoning, treatment modalities and economic costs in Nigeria.

Method:

A retrospective study of childhood drug and non-drug poisoning cases from January 2007 to June 2014 in the University of Port Harcourt Teaching Hospital (UPTH), Port Harcourt, Nigeria was carried out. Medical records were analysed for demographic and aetiological characteristics of poisoned children (0–14 years of age), as well as fiscal impact of poisoning cases.

Findings:

Of the 100 poisoned patients, 46% were male and 54% female, with female/male ratio of 1.17:1. Most of the children were under five years of age. Paracetamol, amitriptyline, chlorpromazine, ferrous sulphate, kerosene, organophosphates, carbon monoxide, snake bite, alcohol and rodenticides were involved in the poisoning. The average cost of poison management per patient was about $168, which is high given the economic status of Nigeria.

Conclusion:

Childhood poisoning is still a significant cause of morbidity among children in Nigeria and accounts for an appreciable amount of health spending, therefore preventive strategies should be considered.

Poisoning substances taken by young people: a population-based cohort study

Background

Globally, poisonings account for most medically-attended self-harm. Recent data on poisoning substances are lacking, but are needed to inform self-harm prevention.

Aim

To assess poisoning substance patterns and trends among 10–24-year-olds across England

Design and setting

Open cohort study of 1 736 527 young people, using linked Clinical Practice Research Datalink, Hospital Episode Statistics, and Office for National Statistics mortality data, from 1998 to 2014.

Method

Poisoning substances were identified by ICD-10 or Read Codes. Incidence rates and adjusted incidence rate ratios (aIRR) were calculated for poisoning substances by age, sex, index of multiple deprivation, and calendar year.

Results

In total, 40 333 poisoning episodes were identified, with 57.8% specifying the substances involved. The most common substances were paracetamol (39.8%), alcohol (32.7%), non-steroidal anti-inflammatory drugs (NSAIDs) (11.6%), antidepressants (10.2%), and opioids (7.6%). Poisoning rates were highest at ages 16–18 years for females and 19–24 years for males. Opioid poisonings increased fivefold from 1998–2014 (females: aIRR 5.30, 95% confidence interval (CI) = 4.08 to 6.89; males: aIRR 5.11, 95% CI = 3.37 to 7.76), antidepressant poisonings three-to fourfold (females: aIRR 3.91, 95% CI = 3.18 to 4.80, males: aIRR 2.70, 95% CI = 2.04 to 3.58), aspirin/NSAID poisonings threefold (females: aIRR 2.84, 95% CI = 2.40 to 3.36, males: aIRR 2.76, 95% CI = 2.05 to 3.72) and paracetamol poisonings threefold in females (aIRR 2.87, 95% CI = 2.58 to 3.20). Across all substances poisoning incidence was higher in more disadvantaged groups, with the strongest gradient for opioid poisonings among males (aIRR 3.46, 95% CI = 2.24 to 5.36).

Conclusion

It is important that GPs raise awareness with families of the substances young people use to self-harm, especially the common use of over-the-counter medications. Quantities of medication prescribed to young people at risk of self-harm and their families should be limited, particularly analgesics and antidepressants.

Patterns and outcome of acute poisoning among children in rural Sri Lanka

Background

The burden of poisoning among children is largely underexplored in rural Sri Lanka. This study describes the patterns of demographic characteristics, poison related factors, clinical management and outcome following acute poisoning among children (9 months- 12 years) in rural Sri Lanka.

Method

This hospital based multi-center study included Anuradhapura Teaching hospital, Polonnaruwa District General hospital, and 34 regional hospitals within Regional Director of Health Services in North Central province of Sri Lanka. The study assessed clinical profiles, poison related factors, clinical management, complications, harmful first aid practices, reasons for delayed management, complications and outcomes following acute poisoning over 7 years.

Results

Among 1621 children with acute poisoning, the majority were in preschool age group. Household chemicals were accountable for 489 acute poisonings (30.2%). The most common poison was kerosene oil, followed by paracetamol. Most events occurred within their own domestic premises. Potentially harmful first aid measures were practiced by approximately one third of care givers. Reasons for delayed presentation at emergency center included lack of concern by family members regarding the urgency of the situation and lack of knowledge regarding possible complications. Complications were observed in 12.5% and the most common complication was chemical pneumonitis.

Conclusions

Children with acute poisoing in rural Sri Lanka were predominantly preschoolers. They are poisonined mostly within their own housing premises. Kerosene oil, in addition to being the most common poison, had additional risks of aspiration pneumonia following potentially hazadrous first aid measures practised by the care givers. Complications though rare were potentially preventable by community education and awareness on timely attention to seek medical care, and avoidance of harmful first aid practices.

Differing patterns in intentional and unintentional poisonings among young people in England, 1998-2014: a population-based cohort study

Background

Accurate and up to date data on changes in poisoning incidence among young people are lacking. Recent linkage of UK primary care, hospital and mortality data allows these to be quantified to inform service delivery.

Methods

An open cohort study of 1 736 527 young people aged 10-24 between 1998 and 2014 was conducted using linked data from the Clinical Practice Research Datalink, Hospital Episode Statistics and Office for National Statistics deaths. Incidence rates (IRs) by poisoning intent were calculated by age, sex, deprivation and year.

Results

Total poisoning IRs increased by 25% from 1998/99 to 2013/14 [adjusted incidence rate ratio (aIRR) 1.25, 95% CI: 1.20-1.30]. Patterns differed markedly by intent. Intentional poisoning rates increased by 52% while unintentional rates remained unchanged. Intentional rates increased almost exclusively among females, gradually between 1998/99 and 2013/14 among 16-18 (88% increase) and 19-24 (36% increase) year olds but only increased among 10-15 year olds in the last 2 years (79% increase). A 2-fold increased risk of poisoning for the most compared to least deprived quintile existed (aIRR 2.21, 95% CI: 2.02-2.23) and remained over time.

Conclusions

Commissioning of primary and secondary prevention services needs to address the growing problem of intentional poisonings among young people.

Changes in poisonings among adolescents in the UK between 1992 and 2012: a population based cohort study

BACKGROUND

Poisonings are a common cause of morbidity and mortality among adolescents. Yet surveillance data indicating current incidence rates (IRs) and time trends are lacking, making policy development and service planning difficult. We utilised population based primary care data to estimate adolescent poisoning rates according to intent across the UK.

METHODS

A cohort study of 1 311 021 adolescents aged 10-17 years, between 1992 and 2012, was conducted using routine primary care data from The Health Improvement Network. IRs and adjusted IRRs with 95% CIs were calculated for all poisonings, intentional, unintentional, unknown intent and alcohol related poisonings, by age, sex, calendar time and socioeconomic deprivation.

RESULTS

Overall poisoning incidence increased by 27% from the period 1992-1996 to 2007-2012, with the largest increases in intentional poisonings among females aged 16-17 years (IR 391.4/100 000 person years (PY), CI 328.9 to 465.7 for age 17 years in 1992-1996; 767.0/100 000 PY, CI 719.5 to 817.7 in 2007-2012) and alcohol related poisonings in females aged 15-16 years (IR 65.7/100 000 PY, CI 43.3 to 99.8 rising to 130.0/100 000 PY, CI 110.0 to 150.0 for age 15 years). A strong socioeconomic gradient for all poisonings persisted over time, with higher rates among the more deprived (IRR 2.63, CI 2.41 to 2.88 for the most vs least deprived quintile in 2007-2012).

CONCLUSIONS

Adolescent poisonings, especially intentional poisonings, have increased substantially over time and remain associated with health inequalities. Social and psychological support for adolescents should be targeted at more deprived communities, and child and adolescent mental health and alcohol support service provision should be commissioned to reflect the changing need.

Acute poisoning in children under the age of six: a two-decade study of hospital admissions and trends

AIM

To evaluate the incidence, clinical features and outcome of acute poisoning in children of less than 6 years of age in northern Finland.

METHODS

Children hospitalized with acute poisoning at the Oulu University Hospital between 1991 and 2010 were retrospectively evaluated from hospital records.

RESULTS

There were 334 hospital admissions due to acute poisoning during the study period, with an overall incidence rate of 5.2 per 10 000 per year, decreasing slightly from 6.7 in 1991-1995 to 4.5 in 2006-2010. Mean length of a hospital stay was 1.2 (SD ± 1.26) days. The most common substances ingested were terbutaline (12.3%), benzodiazepines (12.0%) and dishwasher powder (9.3%). Almost half of the patients were admitted to the paediatric intensive care unit, but most only required supportive care. Specific antidotes were administered in 16 cases. Three patients suffered from aspiration pneumonia as a result of ingesting poison, but no children died during the study.

CONCLUSION

Poisoning is a fairly common cause of hospital admission in children under the age of six. In most cases, their clinical condition is good, and they can be discharged after a short surveillance period.

Acute poisoning in children; a population study in isfahan, iran, 2008-2010

Objective

Acute accidental poisoning in children is still an important public health problem. The epidemiological investigation specific for each country is necessary to determine the extent and characteristics of the problem. The aim of our study was to elucidate the current pattern of acute poisoning among children.

Methods

The present retrospective study describes the epidemiology of acute accidental poisoning in children (less than 10 years old) admitted to the Emergency Department of two teaching hospitals during a period of two years.

Findings

Three hundred and forty four children under 10 years old were admitted to emergency department of two teaching hospitals due to acute accidental poisoning. Drugs were the most common agents causing the poisoning (58.1%), followed by Hydrocarbons (13.1%), and opioids (9.3%). Common signs were neurological (42.6%) with lethargy being the most common (39.1%). 50.6% of cases were discharged from hospital within 6-12 hours, 91.6% of them without any complication.

Conclusion

Accidental poisonings are still a significant cause of morbidity among children in developing countries. Regarding the high prevalence of pharmaceutical drug poisoning and because lethargic was the most frequent neurological sign, comprehensive toxicology screen tests should be included as part of the routine evaluation of children presenting to an ED with an apparent life-threatening event.

Changing trends and predictors of outcome in patients with acute poisoning admitted to the intensive care

BACKGROUND

Acute poisoning in children is a medical emergency and preventable cause of morbidity and mortality. Knowledge about the nature, magnitude, outcome and predictors of outcome is necessary for management and allocation of scant resources.

METHODS

This is a retrospective study conducted in the Pediatric Intensive Care Unit (PICU) of an urban multi speciality teaching and referral hospital in North India from January 1993 to June 2008 to determine the epidemiology, clinical profile, outcome and predictors of outcome in children with acute poisoning. Data of 225 children with acute poisoning was retrieved from case records with respect to demographic profile, time to presentation, PRISM score, clinical features, investigations, therapeutic measures, complications and outcome in terms of survival or death. Survivors and non-survivors were compared to determine the predictors of mortality.

RESULTS

Acute poisoning constituted 3.9% of total PICU admissions; almost all (96.9%) were accidental. The mean age of study patient's was 3.3 ± 3.1 (range 0.10-12) years with majority (61.3%) being toddlers (1-3 years). In the overall cohort, kerosene (27.1%) and prescription drugs (26.7%) were the most common causative agents followed by organophosphates (16.0%), corrosives (7.6%), carbamates (4.9%) and aluminum phosphide (4.9%). However the trends of the three 5-year interval (1993 till the end of 1997, 1998 till the end of 2002 and 2003 till the end of June 2008) revealed a significant decrease in kerosene, aluminum phosphide and iron with increase in organophosphate compound poisoning. Ninety nine (44%) patients required supplemental oxygen, of which nearly half (n = 42; 42.4%) needed mechanical ventilation. Twenty (8.9%) died; cause of death being iron poisoning in five; aluminum phosphide in four; organophosphates in three and one each because of kerosene, diesel, carbamate, corrosive, sewing machine lubricant, isoniazid, salicylate and maduramycin poisoning. There has been a significant decrease in the mortality over the years. The non-survivors were older, had a higher PRISM score and hypotension at admission and higher need for oxygen and ventilation. On multiple logistic regression analysis hypotension at admission was the most significant predictor of death (adjusted odds ratio: 5.59; 95% confidence interval: 1.38-22.63; p = 0.016).

CONCLUSION

Acute poisoning in children over the past 15 years has shown a changing trend with significant decrease in kerosene, iron and aluminum phosphide and an increase in organophosphate and prescription drugs. The overall mortality has decreased significantly. Hypotension at admission was the most significant predictor of death.

Acute poisoning among children admitted to a regional university hospital in Northern Greece

OBJECTIVES

The aim of our study was to elucidate the current pattern of acute poisoning among children admitted to a regional University Hospital in the prefecture of Evros in Northern Greece. We also compared the obtained findings with those of two previous studies performed in the same region.

METHODS

Demographic and clinical data, management, and outcome of children with acute poisoning were recorded in our region, during the past 5-years (2005-2009, period C) and compared to similar studies carried out in the periods 1985-1989 (period A) and 1995-1999 (period B).

RESULTS

Comparison between the three periods showed that in period Athe lower incidence of children's acute poisoning (CAP) was observed. Also this revealed a 20%-reduction in the frequency of poisoning over the past 5-years (period C) compared to period B (p = 0.219), a significant increase in tobacco intoxication over the years (in the order A-C; p < 0.001 for comparisons of periods A and B, and periods B and C), while poisoning from insecticides-pesticides decreased (p < 0.001). The incidence of poisoning via salicylates significantly reduced from 9.7% in period A to 6.2% in period B, and further to 4.7% in period C (p = 0.016), whereas during the same periods poisoning via paracetamol increased from 2.3% to 5.1% and then to 10.4%, respectively (p < 0.001). Atrend toward a higher incidence of suicide attempt via poisoning was found during the three periods (from 3.0% in period A to 4.7% and 6.6%, in periods B and C, respectively; p = 0.049).

CONCLUSIONS

The frequency of acute poisoning among children has decreased over the past 5 years. The incidences of poisoning via paracetamol and tobacco, and attempted suicide have increased in recent years. Targeted and continuous educational preventive programs are mandatory.

Contributing factors in self-poisoning leading to hospital admission in adolescents in northern Finland

AIM

To evaluate the frequencies of different agents used in self-poisonings and acute factors contributing to intoxication of patients aged 12-18 years in northern Finland.

MATERIAL

Retrospective medical record review of all hospitalized patients during the period from January 1, 1991 to December 31, 2006.

OUTCOME MEASURES

Cause of the admission, contributing factors, readmissions within one year.

RESULTS

There were 309 admissions during the period, 54% were females. The leading cause of admission was alcohol, in 222 cases (71.8%). Hospitalizations related to alcohol consumption were associated with accidental poisoning in recreational use. There were no acute contributing factors in the majority of all patients. Over one-third of all intoxications were intentional self-harm, although previously diagnosed psychiatric diseases were rare.

CONCLUSIONS

It is crucial to recognize adolescent psychiatric disorders in time and consult child and adolescent psychiatrist in case of poisoning.

Pattern of pediatric poisoning in the east Karadeniz region between 2002 and 2006: increased suicide poisoning

In the present study, 386 patients with the diagnosis of poisoning admitted to the Pediatric Emergency Unit of Farabi Hospital of Medical Faculty of Karadeniz Technical University between January 2002 and December 2006 were retrospectively evaluated with respect to gender, age, cause of poisoning, type of substance used, route of exposure, reason for the intake, signs and symptoms, time of referral to the hospital, hospitalization period, and prognosis. The age group of most poisoning cases was <5 years of age and constituted 51% (n = 197) of all cases. The main toxic agent was drugs (70.2%), followed by foods (8.8%), rodenticides (7%), insecticides/pesticides (4.9%), and carbon monoxide (4.7%). In childhood poisonings, accidental drug poisoning was frequent in toddlers, whereas suicidal poisoning was frequent in adolescents. The suicidal poisoning rate was 23.8% among all poisoning patients, and 98.9% of these patients were adolescents. The suicidal poisoning rates for males and females were 30% and 70%, respectively. An increase in suicidal and inhalation poisonings was observed when compared with previous studies that have been conducted in the same region. The results of the present study suggest that poisonings still represents an important health problem that could be prevented by safe drug storage at home, as well as parental education on adolescence issues, particularly those regarding females.

Poisoning deaths among Finnish children from 1969 to 2003

AIM

Trends in paediatric deaths due to poisoning are little studied. The aim of this study was to investigate the cause and secular trend of poisoning deaths among Finnish children.

METHODS

Death certificates of all Finnish children aged 0-15 who died due to poisoning between 1969 and 2003 were obtained from the Statistics of Finland and analysed.

RESULTS

During the study period, altogether 121 children aged 0-15 years died from poisoning in Finland. Among 0- to 4-year olds, the incidence of poisoning deaths declined to practically zero by the beginning of 1980s. Most of these deaths were unintentional poisonings. Among 5- to 15-year olds, the incidence of poisoning deaths varied during the study period. In this age group, up to 53% of the deaths were suicides among girls compared with 20% among boys (p = 0.017). The corresponding figures for substance abuse were 54% among boys and 9% among girls (p < 0.001).

CONCLUSION

Despite the declining secular trend seen in paediatric poisoning deaths in Finland from 1969 to 2003, the risk of death from both intentional and unintentional poisoning persists in children. Health programmes should be continued especially to promote well-being in families and to prevent teenage suicides and substance abuse.

Secular trends in poisonings leading to hospital admission among Finnish children and adolescents between 1971 and 2005

OBJECTIVE

To investigate the secular trends in childhood poisonings leading to hospitalization in Finland.

STUDY DESIGN

All children and adolescents age 0 to 19 years hospitalized in Finland with the primary diagnosis of poisoning between 1971 and 2005 were identified using the International Classification of Diseases.

RESULTS

During the study period, there were 41 862 hospitalizations with 96 427 hospital bed days for poisoning in 38 582 children and adolescents. The incidence of hospitalization declined from 91.3 admissions per 100 000 person-years in boys and 105.2 per person-years in girls in 1971 to 64.8 in boys and 83.5 in girls in 2005. In the 0- to 4-year age group, admissions declined by 51%. Hospitalizations for alcohol poisoning increased 1.7-fold (95% confidence interval = 1.4 to 2.2) in boys and 2.4-fold (95% confidence interval = 1.8 to 3.3) in girls. Alcohol poisoning was the primary diagnosis in 53% of those in the 10- to 14-year age group.

CONCLUSIONS

Poisoning remains an important cause of morbidity in Finnish children and adolescents despite the decreased overall incidence of poisonings leading to hospitalization between 1971 and 2005. The increasing trend of hospital admissions for alcohol poisoning, especially in 10- to 14-year-olds, is noteworthy. Effective primary prevention programs and adult supervision should be targeted at reducing alcohol consumption and alcohol-related poisonings in youth.

Poisoning hospitalization correlates with poison center call frequency

INTRODUCTION

Poison Control Centers (PCCs) have been shown to reduce health expenditures by reducing emergency department and clinic visits. The effect or association of PCC call frequency on acute hospitalization rates for poisonings has not been studied extensively.

METHODS

All nonfederal hospital discharges for acute poisoning principal diagnosis codes (960-979, 980-989, 9956X, 3030, and 005) in California between October 1999 and June 2002 were examined. Approximately 3.3% of the discharges had county/hospital information suppressed in the public-use database because of confidentiality criteria and were excluded from the analysis. U.S. Census Bureau population estimates for appropriate years by counties were also obtained. The 58 California counties were condensed to 48 counties and 3 "small-county" geographic groupings. Exposure calls by counties/groupings to the California Poison Control System(CPCS) for the same period were tabulated.

RESULTS

In California, rates of hospital discharges for poisoning averaged 0.54/1000 person years with a range of 0.25/1000 person years (Central Counties) to 1.53/1000 person years (Del Norte County). Poison call rates averaged 8.5/1000 person years with a range of 4.9/1000 person years (Los Angeles County) to 19.6/1000 person years (Napa County). Poisoning discharges per 1000 person years positively correlated with PCC calls per 1000 person years (Spearman correlation 0.41, p = 0.0003). The average hospital length of stay (LOS) did not correlate with PCC call frequency or poisoning discharges per 1000 person years.

CONCLUSION

The CPCS call frequency or county penetrance was not correlated with a reduction in the number of hospitalizations for poisoning nor was it associated with reduced average LOS in this study. Further study is needed to understand the etiology of the large differences in county rates of poisoning hospitalization and average LOS.

Profile of childhood poisoning at a tertiary care centre in North India

OBJECTIVES

To determine the profile and outcome (discharge from emergency room after observation, admission or death) of pediatric patients presenting with acute poisoning to a tertiary care centre in north India.

METHODS

We retrospectively reviewed the last 2 year (July, 2004 to July, 2006) hospital records of pediatric emergency room to profile all cases of pediatric poisoning during that period and noted their outcome. All cases age < or = 12 years with definite history of poisoning were included.

RESULTS

111 patients presented to the pediatric emergency during the study period. Mean age of our patients was 3.12 +/- 2.04 yrs (SD). Majority of our patients (63.9%) was in the 1-3 yr age group. Males outnumbered females by a factor of two; majority of our patients resided in urban areas. Kerosene (27.9%), drugs (19.8%) and insecticides (11.7%) were the agents most frequently implicated. Almost all (96.9%) ingestions were accidental in nature. Thirty six patients (32.4%) were asymptomatic after 6 hr of observation in the emergency ward; 75 patients (67.6%) developed symptoms related to toxic ingestion. The common serious symptoms included altered sensorium, respiratory distress, seizures, ataxia, hypotension, cyanosis and burns; three patients required intubation and mechanical ventilation. Almost one third of our patients underwent gastric lavage; no patient with kerosene poisoning or any other inappropriate indication underwent the same.

CONCLUSION

The trends for pediatric poisoning noted at our centre are not very different from those observed in hospital-based studies conducted more than a decade ago, despite the rapid socioeconomic development in our country. In sharp contrast to developing countries, where majority of poisonings are due to common non-toxic household products, most of our patients require hospitalization because of severe symptoms related to dangerous nature of toxins ingested. Consultation with the poison cell results in improved patient management.

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.

Incidence of poisoning deaths in Finland in 1971–2005

Poisonings cause considerable morbidity and mortality worldwide. However, only few countries have published nationwide statistics on poisoning deaths. Based on the Official Cause-of-Death Statistics of Finland, we investigated the incidence and secular trend of poisoning deaths in Finland in 1971–2005. Alcohol poisoning deaths and other poisoning deaths were analyzed separately. During the 35-year study period, other poisoning deaths (non-alcohol) increased from 2.6/100,000 in men and 1.4/100,000 in women in 1971 to 6.8/100,000 and 3.2/100,000 in 2005, respectively. Alcohol poisoning death rates also increased from 9.6/100,000 in men and 0.7/100,000 in women in 1971 to 16.8/100,000 and 4.2/100,000 in 2005, respectively. In the early 1970s, the incidence rates of alcohol deaths were about 10 times higher in men compared with women, whereas in the last few years of observation, men's incidence rate was only about four times higher. Our study showed that alcohol and other poisoning deaths increased in Finland between 1971 and 2005. Men’s risk was markedly higher than women’s risk, but in the later years, women’s risk was increasing. Poisoning death rates among children and adolescents were low throughout the period.

Paediatric poisonings treated in one Finnish main university hospital between 2002 and 2006

AIM

Acute poisonings are a major cause of morbidity among children. This study aims to describe the incidence and nature of emergency visits for acute paediatric poisoning among Finnish children.

METHODS

All patients younger than 16 years admitted to the Tampere University Hospital's emergency department with a diagnosis of poisoning during 2002-2006 were identified from the Hospital Information System using the International Classification of Diseases (ICD-10).

RESULTS

Altogether 369 emergency visits were diagnosed with poisoning, the overall incidence being 8.1 per 10 000 person-years (95% CI 7.3-9.0). A majority of patients were adolescents aged 10-15 years (48%) and children under 5 years (45%). Boys represented 55% of the cases. Nonpharmaceutical agents were suspected to be the cause in 60.4% and pharmaceuticals in 30.6% of the intoxications. Multiple agents were involved in 8.4% of the cases. Ethanol was the agent in 30.9% of the poisonings. Most patients (78.9%) were hospitalized (median length of stay 1 day). Overall mortality was 0.3%.

CONCLUSION

Acute paediatric poisonings represent a relatively frequent problem in Finland, and remain a life-threatening problem. The high proportion of alcohol poisonings highlights the necessity to develop more effective primary prevention programs.

Acute child poisonings in Oslo: a 2-year prospective study

AIM

To study the current epidemiology, clinical course and outcome of poisonings among children in Oslo and compare findings to a similar study from 1980.

METHODS

Observational study with prospective inclusion of all children (<15 years of age) with a main diagnosis of acute poisoning treated in hospital or outpatient clinic in Oslo for 2 years.

RESULTS

One hundred seventy-five episodes of acute poisoning were included at the outpatient clinic only (n = 65), the paediatric department only (n = 82) or both (n = 28 referrals). Annual incidence was 97 per 100 000, significantly lower than in 1980 (230 per 100 000). Highest incidence was in 1-year-old males (576 per 100 000). In children <8 years of age, the most common toxic agents were pharmaceuticals (39%) and household products (32%); children > or = 8 years ingested mainly ethanol (46%) or pharmaceuticals (36%). Five percent of all children were comatose, and complications were seen in 13%. All children survived without sequelae. Half of the admissions needed treatment; most commonly used treatments were activated charcoal (33%), gastric lavage (9%) and emetics (9%).

CONCLUSION

The incidence of child poisonings in Oslo has significantly reduced since 1980. Only half of the poisonings needed treatment, most of the poisonings were mild and the clinical outcome was good.

The impact of a poison control center on the length of hospital stay for patients with poisoning

While previous research suggests that poison control centers (PCCs) significantly reduce the number of emergency room visits and resultant health care costs for poisonings, little is known regarding the potential impact of the PCC on the length of hospital stay. The aim of this study was to examine whether assistance from a PCC is associated with a shorter length of hospital stay for patients admitted with poisonings. The cases reported to our PCC were matched over a period of 1 yr with the hospital admissions E-coded as poisonings in the Uniform Billing (UB) data maintained by the state health department. The length of hospital stay was then compared between the cases for which a PCC provided assistance (matches) and the cases for which a PCC was not contacted. During the study period, there were 32,245 hospitalizations for poisoning in the UB data and 52,498 poisonings reported to the PCC. The matching process yielded 1719 nonfatal cases. The length of hospital stay for patients who received assistance from a PCC ranged from 0 to 126 d (median = 2.0) and was significantly different compared to a range of 0 to 220 days (median = 5.0) for cases that were never called in to a PCC. The results of this study suggest that patients admitted to hospitals with poisonings who receive PCC assistance have measurable reductions in average hospital stay. Such a decrease may translate into substantial savings in health care costs and resources.

Emergency visits for childhood poisoning: a 2-year prospective multicenter survey in Spain

OBJECTIVES

To describe the characteristics of childhood poisoning leading to consultation to 17 pediatric emergency departments in Spain.

METHODS

During a 2-year period (January 2001 to December 2002), accompanying people of 2157 children with acute intoxication who visited consecutively at the emergency room were prospectively surveyed.

RESULTS

Childhood poisoning accounted for 0.28% of all emergency visits during the study period. The median (interquartile range, 25th-75th percentile) age was 24 months (22-60 months); 67% of children were younger than 4 years. Drug ingestion was involved in 54.7% of cases (paracetamol was the most frequent drug), domestic products in 28.9%, alcohol in 5.9%, carbon monoxide in 4.5%, and illicit drugs in 1.5%. A total of 61.3% of patients were admitted within 1 hour after exposure to the toxic substance, and 10.3% had been already treated before arrival; 29.1% of patients were referred for clinical manifestations which were mostly neurological symptoms. Laboratory tests and other investigations were performed in 40.7% of cases. Gastrointestinal decontamination was used in 51.7% of patients, with activated charcoal in 32.3%. Treatment varied significantly according to the individual hospitals. A total of 83.3% of patients were treated as outpatients, 15.2% were hospitalized, and 1.5% were admitted to the intensive care unit. One 11-month-old boy with carbon monoxide intoxication died. Six patients had permanent sequelae (esophageal stenosis in 5 and partial blindness in 1).

CONCLUSIONS

Young children who accidentally ingested drugs and, less frequently, domestic products accounted for most cases of intoxication who presented at the pediatric emergency department.

Estrogen has mnemonic-enhancing effects in the inhibitory avoidance task

Gonadal hormones, such as estrogen, can alter cognitive performance. The present studies investigated the relationship between performance on the inhibitory avoidance task and endogenous fluctuations in ovarian hormones and estrogen replacement. In Experiment 1, proestrous or diestrous I female, or male, rats were trained in the inhibitory avoidance task. Following a 24-h intertrial delay, when female rats were tested in metestrus or diestrus II, no differences in crossover latencies were observed among groups. In Experiment 2, female rats in proestrus or diestrus I, and male rats, were trained in the inhibitory avoidance task and were tested following a 4-h intertrial delay (so that training and testing were accomplished in the same phase of the cycle). In this paradigm, proestrous rats had significantly longer crossover latencies than did either diestrous I or male rats. Posttraining administration of estrogen, but not progesterone, to ovariectomized rats increased crossover latencies compared to vehicle with a 4-h (Experiment 3) or 24-h (Experiment 4) intertrial delay. In Experiment 5, estrogen administration to ovariectomized rats immediately, but not 1, 2, or 3 h posttraining, increased crossover latencies compared to vehicle. Together, these data suggest that estrogen can have positive mnemonic effects in the inhibitory avoidance task.

The utility of the history and clinical signs of poisoning in childhood: a prospective study

The authors aimed to evaluate the utility of the history and clinical signs for predicting ingestion of poisons in children. A prospective cohort study was performed of all patients presenting with suspected poisoning to a pediatric emergency department over a 13-month period. Clinical data were collected on a preformatted consultation sheet. Urine drug screens (UDS) were analyzed by gas chromatography/mass spectrometry (GC/MS). Serum toxicologic tests were performed when clinically indicated. The sensitivity, specificity, positive predictive values (PPV), and negative predictive values (NPV) of the history and clinical signs were calculated, first using UDS and, second, using all available toxicologic tests as the gold standards. Of 249 patients, 110 (46%) had a UDS performed. The purported poison ingested was potentially identifiable by GC/MS in 57 (52%) of these UDS. Only the results from these 57 UDS were included in our statistical analysis. Overall, the suspected poison was identified in 33 (58%) of the 57 UDS. Similarly, in the less than 5 years age subgroup, 28 (56%) of 50 UDS were positive. Odor on the breath (PPV 100%), followed by symptoms consistent with poisoning (PPV 92%) and presence of poison on clothes (PPV 86%) were the most useful predictors of a positive UDS. Similar results were obtained when all available toxicologic tests were used as the gold standard. The best clinical predictors of poisonous ingestion in children were found to be odor on the breath, symptoms consistent with poisoning, and presence of poison on the patient's clothes. Approximately 40% of children who present with poisoning have not been exposed to the putative toxin.

Poisoning in a paediatric hospital

BACKGROUND

Poisoning is a major cause of morbidity and mortality in children and adolescents. Pharmaceutical and household products are responsible for the majority of cases.

AIM

To analyse poisoning cases presenting to a paediatric hospital.

METHODS

A retrospective study of all poisoning cases presenting to the Accident and Emergency (A&E) department of one hospital over a nine-month period. Children from birth to 15 years of age were included. The cases were categorised into accidental or intentional with or without suicidal intention. Demographic features included age, gender, toxin, location of poisoning, need for admission and mortality.

RESULTS

A total of 148 cases were recorded, 47% were male, 31% were hospitalised and there was no mortality. Of ingestions, 74% were between 1 and 4 years of age and 86% were accidental. Of the intentional, 33% were suicidal, all 12 years or older.

CONCLUSIONS

Few unintentional ingestions in the paediatric group result in serious toxicity. Mortality is rare. There is increasing intentional poisoning and alcohol abuse in adolescents. Poison prevention should be part of all well child visits. Agencies catering for children should carry educational leaflets for parents on how to 'poison proof' a child's environment, as the majority of incidents occur at home.
