Abstract
BACKGROUND The use of central stimulant drugs causes significant morbidity. We describe poisonings with central stimulant drugs and compare the different central stimulants concerning combinations with other drugs, treatment, and clinical course. METHODS: Patients presenting from 1 October 2013 to 31 March 2016 with poisoning related to the recreational use of central stimulant drugs were retrospectively included at a primary care emergency outpatient clinic and at a hospital emergency department in Oslo, Norway. Diagnosis of toxic agents was mainly based on the clinical assessment of the doctor treating the patient. Amphetamine and methamphetamine were co-categorized as amphetamine. RESULTS Among the 1131 cases of acute poisoning with central stimulant drugs at the outpatient clinic, amphetamine was involved in 808 (71.4%), cocaine in 252 (22.3%) methylenedioxymethamphetamine (MDMA) in 104 (9.2%), and methylphenidate in 13 (1.1%). Among the 211 cases at the hospital, amphetamine was involved in 167 (79.1%), cocaine in 60 (28.4%), and MDMA in 38 (18.0%). Amphetamine was frequently combined with opioids (40.1% at the outpatient clinic and 41.9% at the hospital) and benzodiazepines (28.3% and 45.5%), while MDMA often was combined with ethanol (64.4% and 71.1%), as was cocaine (62.7% and 61.7%). Sedation was given in 5.2% and 38.4% of cases, naloxone in 9.4% and 37.0%, and flumazenil in 0.1% and 28.0%. In total, 16.5% of the cases at the outpatient clinic were transferred to a hospital for medical review and 8.5% to a psychiatric hospital. Among the hospital patients, 92.9% were admitted to intensive care. CONCLUSION Amphetamine was the most common central stimulant drug involved in acute poisoning in Oslo, often combined with opioids and benzodiazepines.

COST EFFECTIVENESS AND RESOURCE ALLOCATION 2021; 19:48. [PMID: 34348747 PMCID: PMC8335998 DOI: 10.1186/s12962-021-00303-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2021] [Accepted: 07/28/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Treating patients with acute poisoning by substances of abuse in a primary care emergency clinic has previously been shown to be a safe strategy. We conducted an economic evaluation of this strategy compared to hospital treatment, which is the usual strategy. METHODS Assuming equal health outcomes, we conducted a cost-minimization analysis. We constructed a representative opioid overdose patient based on a cohort of 359 patients treated for opioid overdose at the Oslo Accident and Emergency Outpatient Clinic (OAEOC) from 1.10.2011 to 30.9.2012. Using a health care system perspective, we estimated the expected resources used on the representative patient in primary care based on data from the observed OAEOC cohort and on information from key informants at the OAEOC. A likely course of treatment of the same patient in a hospital setting was established from information from key informants on provider procedures at Drammen Hospital, as were estimates of hospital use of resources. We calculated expected costs for both settings. Given that the treatments usually last for less than one day, we used undiscounted cost values. RESULTS The estimated per patient cost in primary care was 121 EUR (2018 EUR 1.00 = NOK 9.5962), comprising 97 EUR on personnel costs and 24 EUR on treatment costs. In the hospital setting, the corresponding cost was 612 EUR, comprising 186 EUR on personnel costs, 183 EUR on treatment costs, and 243 EUR associated with intensive care unit admission. The point estimate of the cost difference per patient was 491 EUR, with a low-difference scenario estimated at 264 EUR and a high-difference scenario at 771 EUR. CONCLUSIONS Compared to hospital treatment, treating patients with opioid overdose in a primary care setting costs substantially less. Our findings are probably generalizable to poisoning with other substances of abuse. Implementing elements of the OAEOC procedure in primary care emergency clinics and in hospital emergency departments could improve the use of health care resources.

Abstract
Objective: U.S. opioid overdoses increased nearly sixfold from 1999 to 2018, and greater than 1% of all emergency medical services (EMS) encounters now involve naloxone administration. While "treat and release" protocols may have low short-term mortality, the risk of subsequent non-fatal overdoses is not known. This study compares the risk of repeat overdose encounters between patients transported to an emergency department (ED) and those who refused transport after prehospital naloxone administration. Methods: All EMS charts within a large single-tier fire-based urban EMS system between January 1 and August 31, 2018 were reviewed if either naloxone administration or a clinical impression related to opioid overdose was documented. Charts were excluded if there was no documented evidence of an opioid toxidrome (respiratory depression or altered mental status), if there was another clear explanation for the symptoms (e.g., hypoglycemia), or if naloxone was not administered. Ten percent of charts were reviewed by a second author to assess reliability. Cox regression (survival analysis) was used to estimate the risk of a subsequent EMS encounter with naloxone administration following an index encounter with naloxone administration. Results: Of the 2143 charts reviewed, 1311 unique patients with 1600 overdose encounters involving naloxone administration were identified. Inter-rater reliability for chart inclusion was strong [κ = 0.83 (95% CI: 0.72-0.90)]. Police/bystanders administered naloxone in 208/1600 (13.0%) encounters. A substantial proportion of encounters resulted in transport refusal (674/1600, 42.1%). The final Cox model included only refusal vs. acceptance of transport to an ED during the index EMS encounter. Patient age, gender, and naloxone administration prior to EMS arrival were not statistically significant in univariate or multivariable analyses, nor were they significant confounders. Refusal of transport was associated with a hazard ratio of 1.66 (95% CI: 1.23-2.23) for subsequent EMS encounters with naloxone administration. Conclusions: Non-transport after prehospital naloxone administration is associated with an increased risk of subsequent non-fatal overdose requiring EMS intervention. Limitations include the use of a single EMS agency as patients may have had uncaptured overdose encounters in neighboring municipalities.

Abstract
Objective The aims of this study were to assess the characteristics of all acute poisoning admissions among adult emergency department (ED) patients, to identify factors associated with admission and to calculate direct medical cost. Methods Data of 2017 (1st January to 31st December) were collected and analyzed retrospectively using patients’ medical records and hospital invoices. Factors associated with type of hospitalization were identified using appropriate statistics. Results A total of 1,214 hospital admissions were included, accounting for 3.6% of all ED admissions. Men (62.2%) and the age group 21–40 years (43.0%) accounted for the largest proportion. Substances most commonly involved were ethanol (52.9%), benzodiazepines (9.7%), cocaine (4.9%), cannabis (4.6%), antidepressants (4.6%) and psychostimulants (4.6%). A total of 4,561 treatment acts were recorded, most commonly monitoring of vital signs (63.6%) and medication and/or intravenous drip administration (62.9%). Patients were discharged home after having received care in the emergency department (ED-amb) in 54.5% of admissions, were admitted to the emergency-department-24-hours-observation unit (ED-24h) or were hospitalized (Hosp) in 24.6% and 20.9% of admissions, respectively. Factors found to be associated with hospitalization type were age, hour of admission, victim location, degree of severity, use of antidotes, involvement of antidepressants, antipsychotics, psychostimulants, benzodiazepines and ethanol. Total cost was €1,512,346 with an average of €1,287 per admission. Conclusion Poisonings entail a considerable percentage of patients admitted to an ED and financial burden. In particular, ethanol poisonings account for the largest proportion of all ED admissions. Comparison of our figures with other data is hampered by the heterogeneity in inclusion criteria. Availability of a uniform template would facilitate comparison and allow better monitoring policies for prevention and cost reduction.

Abstract
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.

Abstract
Background:: Heroin has had an overwhelming impact on public welfare and health resources. National surveillance data indicate a 25% increase in drug overdose deaths in Ohio between 2012 and 2017, ranking the state second in terms of drug overdose deaths associated with opioids. Objective:: The primary objective of this evaluation was to determine the length of hospital stay in suspected or confirmed heroin overdose. Methods:: This retrospective analysis evaluated adult patients presenting to the emergency department (ED) at Mercy Health St Vincent Medical Center with confirmed or suspected heroin overdose. Patient data were obtained from the International Classification of Diseases, 10th revision, code reports. The study site is a 462-bed academic medical center with a level 1 trauma designation located in downtown Toledo, OH. Results:: One-hundred and one patients were included in this study: 49 presented to the ED and were subsequently admitted, while 52 were evaluated in the ED and discharged. No statistically significant differences in demographic data were identified. The average length of stay for admitted patients was 4.39 days (range = 0-22 days) with an average of 1.91days in the intensive care unit and 2.48 days on a general medicine floor. Higher average amounts of naloxone administered prior to presentation to the ED were found to predict an admission to the intensive care unit (6.48 mg vs 2.43 mg, P = .0208). The most frequent necessary interventions were central line placement (16/49, 32.7%) and mechanical ventilation (15/49, 30.6%). Seven patients (14.3%) experienced a cardiac arrest. Conclusion:: Heroin overdoses continue to require emergent interventions and consume numerous health care resources. Investment in strategies for prevention of overdose and the subsequent utilization of resources is paramount in controlling the heroin epidemic in Ohio and nationally.

Abstract
Background Though substance use is a known risk factor for self-discharge, patients self-discharging during treatment for acute poisoning have not previously been described. We charted characteristics of patients self-discharging during treatment for acute poisoning by substances of abuse looking for associations between self-discharge, repeated poisoning, and death. Methods All patients 12 years and older treated for acute poisoning by substances of abuse at an emergency outpatient clinic in Oslo, Norway, were included consecutively from October 2011 through September 2012. We collected data on gender, age, main toxic agent, suicidal intention, homelessness, history of severe mental illness, and self-discharge. Information on deaths was retrieved from the National Cause of Death Register. We did a multiple logistic regression analysis to look for associations between self-discharge and repeated poisoning and a Cox regression analysis for associations between self-discharge and death. Results During one year, 1731 patients were treated for 2343 episodes of acute poisoning by substances of abuse. Two-hundred-and-sixty-six (15%) patients self-discharged during at least one poisoning episode. Self-discharging patients were older, median age 39 years vs 32 years (p < 0.001), more frequently homeless, 20/266 (8%) vs 63/1465 (4%) (p = 0.035), and the main toxic agent more frequently was an opioid, 82/266 (31%) vs 282/1465 (19%) (p < 0.001). Self-discharge was an independent risk factor for repeated poisoning. The adjusted odds ratio for two or more poisoning episodes during one year among self-dischargers was 3.0 (95% CI 2.2–4.1). The association was even stronger for three or more poisoning episodes, adjusted odds ratio 5.0 (3.3–7.5). In total, there were 34 deaths, 9/266 (3.4%) among self-discharging patients and 25/1465 (1.7%) among patients not self-discharging (p = 0.12). The adjusted hazard ratio for death among self-discharging patients was 1.6 (0.75–3.6). Conclusions Self-discharge was associated with frequent poisonings by substances of abuse. Short-term mortality was doubled among self-discharging patients, though this increase was not statistically significant. Still, the increased risk of repeated poisoning marks self-discharging patients as a vulnerable group who might benefit from targeted post-discharge follow-up measures.

Abstract
Objective We have previously found that 9% of patients treated for acute poisoning by substances of abuse in a primary care emergency outpatient setting presented with a new poisoning within a week. We now identify factors associated with rapidly repeated acute poisoning by substances of abuse. Results In 169/1952 (9%) cases of acute poisoning by substances of abuse included consecutively from October 2011 through September 2012 at a primary care emergency outpatient clinic in Oslo, Norway, the patient re-presented within a week with a new poisoning. Homeless patients were more likely to re-present, adjusted odds ratio (AOR) 2.0 (95% confidence interval (CI) 1.3–3.2, p = 0.003), as were self-discharging patients, AOR 1.7 (95% CI 1.2–2.4, p = 0.007), and patients with an opioid as main toxic agent, AOR 1.5 (95% CI 1.0–2.3, p = 0.028). There was no statistically significant association between rapid re-presentation and severe mental illness or suicidal intention.

Abstract
Background: Although the United States and numerous other countries are amidst an opioid overdose crisis, access to safe injection facilities remains limited. Methods: We used prospective data from ambulance journals in Oslo, Norway, to describe the patterns, severity, and outcomes of opioid overdoses and compared these characteristics among various overdose locations. We also examined what role a safe injection facility may have had on these overdoses. Results: Based on 48,825 ambulance calls, 1054 were for opioid overdoses from 465 individuals during 2014 and 2015. The rate of calls for overdoses was 1 out of 48 of the total ambulance calls. Males made up the majority of the sample (n = 368, 79%), and the median age was 35 (range: 18-96). Overdoses occurred in public locations (n = 530, 50.3%), the safe injection facility (n = 353, 33.5%), in private homes (n = 83, 7.9%), and other locations (n = 88, 8.3%). Patients from the safe injection facility and private homes had similarly severe initial clinical symptoms (Glasgow Coma Scale median =3 and respiratory frequency median =4 breaths per minute) when compared with other locations, yet the majority from the safe injection facility did not require further ambulance transport to the hospital (n = 302, 85.6%). Those overdosed in public locations (odds ratio [OR] = 1.66, 95% confidence interval [CI] = 1.17-2.35), and when the safe injection facility was closed (OR =1.4, 95% CI =1.04-1.89), were more likely to receive transport for further treatment. Conclusions: Our findings suggest that the opening hours at the safe injection facility and the overdose location may impact the likelihood of ambulance transport for further treatment.

Abstract
AIMS Despite the excess mortality and morbidity associated with acute poisoning by substances of abuse, follow-up is frequently not organised. We assessed morbidity, including repeated poisoning, and follow-up after acute poisoning by substances of abuse through charting contacts with health services. We also charted short-term mortality. METHODS Patients 12 years and older treated for acute poisoning by substances of abuse at a primary care emergency outpatient clinic in Oslo, Norway, were included consecutively from October 2011 through September 2012. We retrieved information from national registers on fatalities, hospital admissions, and contacts at outpatient specialist health services and with general practitioners (GPs), during the 90 days following a poisoning episode. RESULTS We included 1731 patients treated for 2343 poisoning episodes. During the 90 days following the poisoning, 31% of the patients were treated at somatic hospitals, 9% admitted to psychiatric hospitals, 37% in treatment at outpatient psychiatric/addiction specialist health services, 55% saw their GP, while 34% had no follow-up. The short-term mortality rate was 2.0%, eight times higher than expected. Increasing age, suicidal intention, opioid poisoning, and severe mental illness were associated with increased risk of death. Increasing age, male gender, opioid poisoning, and severe mental illness were associated with repeated poisoning. Patients with increased risk of repeated poisoning were more likely to be in follow-up at outpatient specialist psychiatric/addiction services and in contact with their GP. CONCLUSIONS Follow-up measures seem targeted to those most in need, though one out of three had none. The mortality rate calls for concern.

Madah-Amiri D, Myrmel L, Brattebø G. Intoxication with GHB/GBL: characteristics and trends from ambulance-attended overdoses. Scand J Trauma Resusc Emerg Med 2017; 25:98. [PMID: 28938889 PMCID: PMC5610436 DOI: 10.1186/s13049-017-0441-6] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2017] [Accepted: 09/13/2017] [Indexed: 11/25/2022] Open
Abstract
BACKGROUND Overdoses from so-called "club drugs" (GHB/GBL) have become a more frequent cause of overdoses attended by ambulance services. Given its availability, affordability, and lack of awareness of risks, there is a common misconception among users that the drug is relatively safe. METHODS This study reviewed ambulance records in Bergen, Norway between 2009 and 2015 for cases of acute poisonings, particularly from suspected GHB/GBL intoxication. RESULTS In total, 1112 cases of GHB and GBL poisoning were identified. GHB was suspected for 995 (89%) of the patients. Men made up the majority of the cases (n = 752, 67.6%) with a median age of 27 years old. Temporal trends for GHB/GBL overdoses displayed a late-night, weekend pattern. The most frequent initial symptoms reported were unconsciousness, or reduced consciousness. Most of the patients required further treatment and transport. During the period from 2009 to 2015, there was a nearly 50% decrease in GHB/GBL overdoses from 2013 to 2014. DISCUSSION The characteristics of GHB/GBL overdose victims shed light on this patient group. The decrease in incidence over the years may be partly due to a legal ban on GBL in Norway, declared in 2010. It may also be due to an increase in the use of MDMA/ecstasy. CONCLUSION The review of ambulance records on the prehospital treatment of overdoses can be beneficial in monitoring, preparing, and prevention efforts aimed to benefit this vulnerable group.

Abstract
OBJECTIVE To characterise acute poisonings in pregnant and non-pregnant women treated at emergency departments of government hospitals in Addis Ababa, Ethiopia, between 2010 and 2015. METHODS All data for acutely poisoned women were retrospectively collected from patient medical charts at the emergency departments of Saint Paul's Hospital Millennium Medical College, Ras Desta Memorial Hospital, Yekatit 12 Hospital Medical College and Zewditu Memorial Hospital. Data were collected by extraction questionnaire and analysed using SPSSv. 20 statistical software. RESULTS During the study period, 998 cases of acutely poisoned women were listed in the hospital registries. Of these, complete data for inclusion in the study were available for 592. 36.3% of the study participants were in the age group of 20-24, with a mean (±SD) age of 23.03 (±6.3) years. 80.9% were from Addis Ababa; 4.6% were pregnant. The mean arrival time of all cases was 4.14 h. 85.5% of all study cases were due to intentional self-poisoning, of whom 42.1% were discharged without complications. The most common poisons were bleach and organophosphates; 25.9% of pregnant cases and 32.6% of non-pregnant cases were poisoned by bleach; and 18.5% of pregnant cases and 18.9% of non-pregnant cases had organophosphate poisoning. 0.7% had a history of poisoning; all were non-pregnant women. The common route of poison exposure was oral, and the case fatality rate of organophosphate poisoning in pregnant and non-pregnant women was 20 and 1.87%, respectively. The pre-hospital intervention for the majority of the women was milk, in 12.0% of cases. CONCLUSION Acute poisoning remains a public health problem in our community. Bleach is the most common poisons. Our present findings indicate the necessity of educational programmes on preventable reasons of acute poisonings and their outcomes on pregnant and non-pregnant women.

Abstract
Background Most fatal poisonings occur outside the hospital and the victims found dead. The purpose of this study was to determine the general pattern and patient demographics of fatal poisonings in Northern Finland. In particular, we wanted to analyze differences between pre-hospital and in-hospital deaths. Methods All fatal poisonings that occurred in Northern Finland in 2007–2011 were retrieved from the Cause of Death Registry provided by Statistics Finland. We noted the patient demographics, causal agents, and other characteristics of the poisoning events. Results A total of 689 fatal poisonings occurred during the study period, of which only 42 (6.1%) reached the hospital alive. Those who died pre-hospital were significantly younger (50 vs. 56 years, p = 0.04) and more likely to be male (77% vs. 57%, p = 0.003). Cardiopulmonary resuscitation was attempted less often in pre-hospital cases (9.9% vs. 47.6%, p < 0.001). Ethanol was more frequently the main toxic agent in pre-hospital deaths (58.4% vs. 26.2%, p < 0.001), and multiple ingestions were more common (52.2% vs. 35.7%, p < 0.001) in pre-hospital deaths. Discussion Most of the pre-hospital fatal poisoning victims are found dead and the majority of in-hospital victims are admitted to hospital in an already serious condition. According to results of this and former studies, prevention seems to be the most important factor in reducing deaths due to poisoning. Conclusions The majority of poisoning-related deaths occur pre-hospital and are related to alcohol intoxication and multiple ingestions.

Abstract
BACKGROUND Non-accidental non-fatal poisoning (NANFP) is associated with high risk of repeat episodes and fatality. This cross-sectional study aims to describe the data sources and epidemiology of non-fatal poisonings (NFPs) presenting to the emergency ambulance service. METHODS We assessed incidents of NFP across Wales from electronic ambulance call centre records and paper records completed by attending ambulance crews, December 2007 to February 2008. We descriptively analysed data completed by attending crews. RESULTS 92 331 calls were made to the ambulance call centre, of which 3923 (4.2%) were coded as 'overdose' or 'poisoning'. During the same period, ambulance crews recorded 1827 attended NANFP incidents in those categories, of which 1287 (70.4%) had been identified in the call centre. 76.1% (1356/1782) were aged 15-44 years and 54.2% (991/1827) were female. 75.0% (1302/1753) of incidents occurred in areas from the lower 2 quintiles of deprivation in Wales. Substance taken was reported in 90% of cases (n=1639). Multiple ingestion was common (n=886, 54.1%). Psychotropic was the most frequently taken group of substances (n=585, 32.0%) and paracetamol (n=484, 26.5%) was the most frequently taken substance prehospital. Almost half of patients had taken alcohol alongside other substances (n=844, 46.2%). Naloxone was the most frequently administered treatment (n=137, 7.5%). Only 142/1827 (7.8%) patients were not transported to hospital, of whom 4 were recorded to have been given naloxone. CONCLUSIONS We report new data on the epidemiology of NFP across substance types at national level, highlighting deficiencies in information systems and high levels of multiple ingestion. In order to develop policy and practice for this patient group prehospital and further along the care pathway, information systems need to be developed to allow accurate routine monitoring of volume, presentation and outcomes.

Follow-up of young patients after acute poisoning by substances of abuse: a comparative cohort study at an emergency outpatient clinic. BMC Res Notes 2016; 9:398. [PMID: 27506676 PMCID: PMC4979110 DOI: 10.1186/s13104-016-2200-6] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2016] [Accepted: 08/03/2016] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Young patients with acute poisoning by substances of abuse have increased mortality rates in the long term. In Oslo, Norway, most of these patients are treated at the Oslo Accident and Emergency Outpatient Clinic. The majority were discharged without follow-up. In 2010, the clinic implemented an intervention program for patients under the age of 23 presenting with acute poisoning by substances of abuse. The intervention was a brief motivational interview with a social worker before discharge, followed by a telephone consultation. Patients in need of further follow-up were identified and referred. Our objective was to study short-term effects of the intervention program on referrals to follow-up and repetition rates of acute poisoning. METHODS Comparative cohorts were derived from studies of acute poisoning at the Oslo Accident and Emergency Outpatient Clinic in 2003, 2008 and 2012. Two age groups of patients presenting with acute poisoning by substances of abuse were included: 16-22 years and 23-27 years. Patients in the pre-intervention cohorts of 2003 and 2008 were compared with patients of the same age in the post-intervention cohort of 2012. Repetition rates were estimated using survival analysis. In total, 1323 patients were included; 422 in the younger pre-intervention group, 366 in the younger post-intervention group, 288 in the older pre-intervention group, and 247 in the older post-intervention group. Overall, the major toxic agents were ethanol 823/1323 (62 %) and opioids 215/1323 (16 %). 719/1323 (54 %) patients were male. RESULTS In the younger groups referrals to follow-up increased from 86/317 (27 %) to 156/366 (43 %) (p < 0.001) after the implementation of the program. Among the older patients, who were not included in the program, there was no significant change in referrals. There was no change in the repetition rate of acute poisoning in either age group. The program established contact with 225/366 (61 %) of the eligible patients. CONCLUSION More patients were referred to follow-up after the intervention. We expect this to have a beneficial effect on their substance use and reduce excess morbidity and mortality in the long term. There was no change in the repetition rate of poisoning.

Abstract
Background Procedures for the clinical assessment of acute poisoning by substances of abuse should identify patients in need of hospital admission and avoid hazardous discharges, while keeping the observation time short. We assess the safety of a systematic procedure developed at the Oslo Accident and Emergency Outpatient Clinic (OAEOC). Methods All patients 12 years and older treated for acute poisoning by substances of abuse at the OAEOC were included consecutively from October 2011 to September 2012. Data were collected on pre-set registration forms. Information on re-presentations to health services nation-wide during the first week following discharge was retrieved from the Norwegian Patient Register and from local electronic medical records. Information on fatalities was obtained from the Norwegian Cause of Death Registry. Results There were 2343 cases of acute poisoning by substances of abuse. The main toxic agent was ethanol in 1291 (55 %) cases, opioids in 539 (23 %), benzodiazepines in 194 (8 %), central stimulants in 132 (6 %), and gamma-hydroxybutyrate (GHB) in 105 (4 %). Median observation time was four hours. The patient was hospitalised in 391 (17 %) cases. Two patients died during the first week following discharge, both from a new opioid poisoning. Among 1952 discharges, 375 (19 %) patients re-presented at the OAEOC or a hospital within a week; 13 (0.7 %) with a diagnosis missed at the index episode, 169 (9 %) with a new poisoning, 31 (2 %) for follow-up of concomitant conditions diagnosed at index, and 162 (8 %) for unrelated events. Among the patients with missed diagnoses, five needed further treatment for the same poisoning episode, two were admitted with psychosis, one had hemorrhagic gastritis, another had fractures in need of surgery and four had minor injuries. Conclusion The procedure in use at the OAEOC can be considered safe and could be implemented elsewhere. The high re-presentation rate calls for better follow-up.

Abstract
CONTEXT Routine biological tests are frequently ordered in self-poisoning patients, but their clinical relevance is poorly studied. MATERIALS AND METHODS This is a prospective multicentric observational study conducted in the emergency departments and intensive care units of 5 university and nonuniversity French hospitals. Adult self-poisoning patients without severely altered vital status on admission were prospectively included. RESULTS Routine biological test (serum electrolytes and creatinine, liver enzymes, bilirubin, blood cell count, prothrombin time) ordering and results were analyzed. A total of 1027 patients were enrolled (age, 40.2 ± 14 years; women, 61.5%); no patient died during the hospital stay. Benzodiazepine was suspected in more than 70% of cases; 65% (range, 48%-80%) of patients had at least 1 routine biological test performed. At least 1 abnormal test was registered in 23% of these patients. Three factors were associated with abnormal test results: age older than 40 years, male sex, and poisoning with a drug known to alter routine tests (ie, acetaminophen, NSAIDs, metformine, lithium). Depending on these factors, abnormal results ranged from 14% to 48%. Unexpected severe life-threatening conditions were recorded in 6 patients. Only 3 patients were referred to the intensive care unit solely because of abnormal test results. CONCLUSION Routine biological tests are commonly prescribed in nonsevere self-poisoning patients. Abnormal results are frequent but their relevance at bedside remains limited.

Abstract
BACKGROUND Use of and acute poisoning by substances of abuse represent a major health problem and are often linked to social destitution. We describe associations between place of residence, living conditions and the incidence of poisoning by substances of abuse in Oslo. MATERIAL AND METHOD All patients who were 12 years of age or older and resident in Oslo and who were treated for acute poisoning by substances of abuse at the Oslo Accident and Emergency Outpatient Clinic (OAEOC) were included prospectively for a continuous period of one year, from October 2011 to September 2012. The 15 districts of Oslo were categorised into three groups of living conditions, from the best (I) to the poorest (III) living conditions, based on the City of Oslo's living conditions index. Homeless people were grouped separately. The incidence of poisoning by substances of abuse treated in the OAEOC was estimated. RESULTS Of a total of 1,560 poisonings by substances of abuse, 1,094 cases (70%) affected men. The median age was 41 years. The most frequent toxic agents were ethanol, with 915 cases (59%), and heroin, with 249 cases (16%). The incidence of poisoning by substances of abuse treated in the OAEOC per year per 1,000 inhabitants amounted to 1.75 in living conditions group I, to 2.76 in living conditions group II and 3.41 in living conditions group III. Living conditions group III had a significantly higher incidence than living conditions group II (p < 0.001), and living conditions group II had a significantly higher incidence than living conditions group I (p < 0.001). INTERPRETATION The incidence of acute poisoning by substances of abuse was higher, the poorer the living conditions in the district.

Abstract
AIMS To assess whether people who inject drugs (PWID) and who are treated for overdose by ambulance services have a greater mortality risk compared with other PWID, and to compare mortality risk within potentially critical time-periods (1 week, 1 month, 3 months, 6 months, 1 year, 5 years) after an overdose attendance with the mortality risk within potentially non-critical time-periods (time before and/or after critical periods). DESIGN A prospective cohort study. SETTING Oslo, Norway. PARTICIPANTS A total of 172 PWID street-recruited in 1997 and followed-up until the end of 2004. MEASUREMENTS Interview data linked to data from ambulance records, Norwegian Correctional Services, Opioid Substitution Treatment records and National Cause of Death Registry. Separate Cox regression models (one for each critical time-period) were estimated. FINDINGS Ambulance services treated 54% of the participants for an overdose during follow-up. The mortality rate was 2.8 per 100 person-years for those with an overdose and 3.3 for those without; the adjusted hazard ratio (HR) was 1.3 (95% CI = 0.6, 2.6, P = 0.482). Mortality risk was greater in all but the shortest critical time-period following ambulance attendance than in the non-critical periods. The mortality risk remained significantly elevated during critical periods, even when adjusted for total time spent in prison and substitution treatment. The HR ranged from 9.4 (95% CI = 3.5, 25.4) in the month after an overdose to 13.9 (95% CI = 6.4, 30.2) in the 5-year period. CONCLUSIONS Mortality risk among people who inject drugs is significantly greater in time-periods after an overdose attendance than outside these time-periods.

Abstract
BACKGROUND In Oslo, the majority of patients with acute poisoning are treated in primary care, at an emergency outpatient clinic with limited diagnostic and treatment resources. We describe the poisonings currently seen in this setting. We compare our findings with previous studies, with special concern for the appearance of new toxic agents, and changes in overall numbers and patterns of poisoning. METHODS Observational study. Patients above the age of 12 years presenting at Oslo Accident and Emergency Outpatient Clinic (Oslo Legevakt) with acute poisoning were included consecutively from October 2011 through September 2012. Physicians and nurses registered data on preset forms. Main outcome measures were toxic agents, age, sex, intention, referral and time of presentation. RESULTS There were 2923 episodes of acute poisoning in 2261 patients. Median age of the patients was 32 years, and 1430 (63%) were males. The most frequent toxic agents were ethanol in 1684 (58%) episodes, heroin in 542 (19 %), benzodiazepines in 521 (18%), amphetamine in 275 (9%), fire smoke in 192 (7%), gamma-hydroxybutyrate (GHB) in 144 (5%), and cannabis in 143 (5%). In 904 (31%) poisonings there were more than one toxic agent. In 493 episodes (17%), the patient was hospitalised, and in 60 episodes (2%) admitted to a psychiatric ward. Most poisonings, 2328 (80%), were accidental overdoses with substances of abuse, 276 (9%) were suicide attempts, and 312 (11%) were accidents. Among ethanol poisonings in patients above the age of 26 years, 685/934 (73%) were in males, and 339/934 (36%) presented during weekends. However, among ethanol poisonings in patients under the age of 26 years, 221/451 (49 ) were in females, and 297/451 (66%) presented during weekends. CONCLUSIONS The poisonings treated in this primary care setting were mostly due to accidental overdoses with ethanol or other substances of abuse. There is a disconcerting weekend drinking pattern among adolescents and young adults, with young females presenting as often as young males with ethanol poisoning.

Abstract
BACKGROUND/AIMS Caustic ingestion can cause severe injury to upper gastrointestinal tract. There were few studies about clinical characteristics and treatments of caustic injury in Korea. We investigated the changes in clinical features of caustic injury over the past 20 years including pattern of endoscopic mucosal injury and treatment modality. METHODS This study was a retrospective review of medical records from patients with caustic injury from September 1993 through December 2012. Patients were classified into two groups based on the year when caustic ingestion occurred: patients who visited the hospital from 1993 to 2002 (early group) and patients who visited the hospital from 2003 to 2012 (late group). RESULTS A total 140 patients were included (early group [n=50] vs. late group [n=90]). Annual number of caustic ingestions did not show decreasing tendency over the past 20 years. Alkali ingestion increased (20.0% vs. 65.6%, p<0.001) and cases with more than grade 2b of esophageal mucosal injury decreased (41.3% vs. 20.7%, p=0.012) in late group. There were no differences between two groups in sex, age, proportion of accidental ingestion, and systemic/gastrointestinal complications. Use of gastric lavage (p<0.01) and broad spectrum antibiotics (p=0.03) decreased in late group. However, there was no difference in use of steroid between two groups. CONCLUSIONS In this study, overall caustic ingestion did not decrease and ingestion of alkali agents increased over the past 20 years. Tighter legislation on caustic agents is required and we need to be alert to the best management of caustic injury.

Abstract
OBJECTIVES Severely poisoned patients can benefit from intensive and specific treatments. Emergency medical services (EMS) may therefore play a crucial role by matching prehospital care and hospital referral to the severity of poisoned patients. Our aim was to investigate EMS accuracy in this condition. METHODS A 3-year retrospective study was conducted in a university hospital. Emergency telephone calls about adult patients with intentional drug poisoning (IDP) were included. In daily practice, an emergency physician answers such telephone calls and dispatches either first responders or a mobile intensive care unit (MICU). According to on-scene evaluation, patients are referred to the emergency department (ED) or to an intensive care unit (ICU). We therefore calculated global EMS accuracy according to patients' actual medical needs. We further evaluated the performance of dispatch and hospital referral decision. We also performed a regression analysis to identify factors of inappropriate dispatch. RESULTS A total of 2,227 patients were studied. Median age was 41 years old (range 30-49) and 63% were women. Dispatch was appropriate for 1,937 (87%) patients. Sensitivity and specificity of dispatch decision were 0.43 and 0.93, respectively. Decision of patients' referral to an appropriate hospital facility had a sensitivity of 0.67 and a specificity of 0.98. Toxicological data, age, and Glasgow coma scale were significantly associated with inappropriate EMS decisions. CONCLUSIONS A physician-operated EMS is an accurate system to provide prehospital care to IDP patients. However, dispatch physicians should pay attention, especially to toxicological anamnesis, to anticipate proper patient care.

Abstract
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.

Abstract
Background The long-term mortality after prehospital treatment for acute poisoning has not been studied previously. Thus, we aimed to estimate the five-year mortality and examine the causes of death and predictors of death for all acutely poisoned patients treated in ambulances, the emergency outpatient clinic, and hospitals in Oslo during 2003–2004. Methods A prospective cohort study included all adults (≥16 years; n=2045, median age=35 years, male=58%) who were discharged after treatment for acute poisoning in ambulances, the emergency outpatient clinic, and the four hospitals in Oslo during one year. The patients were observed until the end of 2008. Standardized mortality rates (SMRs) were calculated and multivariate Cox regression analysis was applied. Results The study comprised 2045 patients; 686 treated in ambulances, 646 treated in the outpatient clinic, and 713 treated in hospitals. After five years, 285 (14%) patients had died (four within one week). The SMRs after ambulance, outpatient, and hospital treatment were 12 (CI 9–14), 10 (CI 8–12), and 6 (CI 5–7), respectively. The overall SMR was 9 (CI 8–10), while the SMR after opioid poisoning was 27 (CI 21–32). The most frequent cause of death was accidents (38%). In the regression analysis, opioids as the main toxic agents (HR 2.3, CI 1.6–3.0), older age (HR 1.6, CI 1.5–1.7), and male sex (HR 1.4, CI 1.1–1.9) predicted death, whereas the treatment level did not predict death. Conclusions The patients had high mortality compared with the general population. Those treated in hospital had the lowest mortality. Opioids were the major predictor of death.

Abstract
Background Up to date information on poisoning trends is important. This study reports the epidemiology of all hospitalized acute poisonings in Oslo, including mortality, follow-up referrals, and whether the introduction of over-the-counter sales of paracetamol outside pharmacies had an impact on the frequency of poisonings. Methods All acute poisonings of adults (≥16 years) treated at the five hospitals in Oslo from April 2008 to April 2009 were included consecutively in an observational cross-sectional multicentre study. A standardized form was completed by the treating physician, which covered the study aims. All deaths by poisoning in and outside hospitals were registered at the Institute of Forensic Medicine. Results There were 1065 hospital admissions of 912 individuals; 460 (50%) were male, and the median age was 36 years. The annual incidence was 2.0 per 1000. The most frequent toxic agents were ethanol (18%), benzodiazepines (15%), paracetamol (11%), and opioids (11%). Physicians classified 46% as possible or definite suicide attempts, 37% as accidental overdoses with substances of abuse (AOSA), and 16% as other accidents. Twenty-four per cent were discharged without any follow-up and the no follow-up odds were highest for AOSA. There were 117 deaths (eight in hospital), of which 75% were males, and the median age was 41 years. Thus, the annual mortality rate was 25 per 100 000 and the in-hospital mortality was 0.8%. Opioids were the most frequent cause of death. Conclusions The incidence of hospitalized acute poisonings in Oslo was similar to that in 2003 and there was an equal sex distribution. Compared with a study performed in Oslo in 2003, there has been an increase in poisonings with a suicidal intention. The in-hospital mortality was low and nine out of ten deaths occurred outside hospitals. Opioids were the leading cause of death, so preventive measures should be encouraged among substance abusers. The number of poisonings caused by paracetamol remained unchanged after the introduction of over-the-counter sales outside pharmacies and there were no deaths, so over-the-counter sales may be considered safe.

Abstract
Objectives Changes in poisoning trends may affect both complications and outcomes in patients with acute poisoning. This study reports the treatments given and the frequency of complications, also related to treatment, mortality and sequelae related to various toxic agents. Methods All acute poisonings in adults (≥16 years) admitted to the five hospitals in Oslo were included consecutively during one year (2008 to 2009) in an observational cross-sectional multicenter study. A standardized form was completed by the treating physician, which covered the study aims. Results There were 1065 admissions in 912 patients. The median length of hospital stay was one day, and 49% were observed in an intensive care unit (ICU). Active treatment was given to 83%, and consisted of supportive therapy (70%), antidote(s) (38%), activated charcoal (16%) and gastric lavage (9%). The most commonly used antidotes were flumazenil (19%), naloxone (17%) and N-acetylcysteine (11%). The rate of treatment-related complications was 2.4% (21/884). Neither flumazenil, naloxone, nor the combination, was associated with convulsions or other complications. Among those receiving N-acetylcysteine, 5% (6/120) developed allergic reactions, one of which mandated discontinuation of treatment. Nineteen percent presented in a coma. Complications developed in 30%, compared with 18% in a 2003 study, mainly respiratory depression (12%), prolonged QTc interval (6%) and hypotension (5%). Eight patients died (0.8%) and five (0.5%) survived with permanent sequelae, mainly anoxic brain damage. Discussion Few patients stayed more than two days. The use of the ICU was liberal, considering that only one out of five presented in a coma. Antidotes were frequently given diagnostically. Although N-acetylcysteine induced allergic reactions, most were mild and treatment discontinuation was only necessary once. The frequency of complications had almost doubled in five years, although the poisoning pattern was largely unchanged. However, few patients developed permanent sequelae.

Abstract
BACKGROUND In Norway, general practitioners serve as gatekeepers for specialist psychiatric care. Out-of-hours primary healthcare (i.e. casualty clinics) is responsible for the major part of acute psychiatric referrals. There are concerns regarding regular general practitioners' (rGPs') role in emergency psychiatric care of their enlisted patients. Also, the quality of casualty clinics' care and their gatekeeper function are questioned. AIMS To investigate differences between acute admissions to a psychiatric hospital from casualty clinics, rGPs, specialist psychiatric services and other specialist services regarding characteristics of patients and circumstances of the referrals. METHODS A prospective observational study. In the period of 1 May 2005 to 30 April 2008, anonymous information was recorded for all consecutive admissions (n = 5317) to the psychiatric acute unit (PAU) at a psychiatric hospital serving 400,000 inhabitants. The recorded information was: referring agent, circumstances of the referral, patient characteristics, and assessments by the receiving psychiatric resident and the therapist in charge of treatment at the PAU. RESULTS There were only small differences between patients referred to PAU from casualty clinics, rGPs, specialist psychiatric services and other specialist services. The referrals from the different referring agents seemed equally well founded. However, the casualty clinics used more police assistance and coercion, and legal basis for admissions was more frequently converted than for other referring agents. CONCLUSION Casualty clinics seem to function adequately as gatekeepers. The high proportion of casualty clinic referrals with converted legal basis might indicate unnecessary use of coercion.

Abstract
BACKGROUND Most patients with acute poisoning are treated as outpatients worldwide. In Oslo, these patients are treated in a physician-led outpatient clinic with limited diagnostic and treatment resources, which reduces both the costs and emergency department overcrowding. We describe the poisoning patterns, treatment, mortality, factors associated with hospitalization and follow-up at this Emergency Medical Agency (EMA, "Oslo Legevakt"), and we evaluate the safety of this current practice. METHODS All acute poisonings in adults (> or = 16 years) treated at the EMA during one year (April 2008 to April 2009) were included consecutively in an observational study design. The treating physicians completed a standardized form comprising information needed to address the study's aims. Multivariate logistic regression analysis was used to identify the factors associated with hospitalization. RESULTS There were 2348 contacts for 1856 individuals; 1157 (62%) were male, and the median age was 34 years. The most frequent main toxic agents were ethanol (43%), opioids (22%) and CO or fire smoke (10%). The physicians classified 73% as accidental overdoses with substances of abuse taken for recreational purposes, 15% as other accidents (self-inflicted or other) and 11% as suicide attempts. Most (91%) patients were treated with observation only. The median observation time until discharge was 3.8 hours. No patient developed sequelae or died at the EMA. Seventeen per cent were hospitalized. Gamma-hydroxybutyric acid, respiratory depression, paracetamol, reduced consciousness and suicidal intention were factors associated with hospitalization. Forty-eight per cent were discharged without referral to follow-up. The one-month mortality was 0.6%. Of the nine deaths, five were by new accidental overdose with substances of abuse. CONCLUSIONS More than twice as many patients were treated at the EMA compared with all hospitals in Oslo. Despite more than a doubling of the annual number of poisoned patients treated at the EMA since 2003, there was no mortality or sequelae, indicating that the current practice is safe. Thus, most low- to intermediate-acuity poisonings can be treated safely without the need to access hospital resources. Although the short-term mortality was low, more follow-up of patients with substance abuse should be encouraged.

Abstract
Ingestion of corrosive substances may cause severe to serious injuries of the upper gastrointestinal tract and the poisoning can even result in death. Acute corrosive intoxications pose a major problem in clinical toxicology since the most commonly affected population are the young with psychic disorders, suicidal intent and alcohol addiction. The golden standard for determination of the grade and extent of the lesion is esophagogastroduodenoscopy performed in the first 12-24 hours following corrosive ingestion. The most common late complications are esophageal stenosis, gastric stenosis of the antrum and pyloris, and rarely carcinoma of the upper gastrointestinal tract. Treatment of the acute corrosive intoxications include: neutralization of corrosive agents, antibiotics, anti-secretory therapy, nutritional support, collagen synthesis inhibitors, esophageal dilation and stent placement, and surgery.

Abstract
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.

Abstract
Background Acute poisonings are common and are treated at different levels of the health care system. Since most fatal poisonings occur outside hospital, these must be included when studying characteristics of such deaths. The pattern of toxic agents differs between fatal and non-fatal poisonings. By including all poisoning episodes, cause-fatality rates can be calculated. Methods Fatal and non-fatal acute poisonings in subjects aged ≥16 years in Oslo (428 198 inhabitants) were included consecutively in an observational multi-centre study including the ambulance services, the Oslo Emergency Ward (outpatient clinic), and hospitals, as well as medico-legal autopsies from 1st April 2003 to 31st March 2004. Characteristics of fatal poisonings were examined, and a comparison of toxic agents was made between fatal and non-fatal acute poisoning. Results In Oslo, during the one-year period studied, 103 subjects aged ≥16 years died of acute poisoning. The annual mortality rate was 24 per 100 000. The male-female ratio was 2:1, and the mean age was 44 years (range 19-86 years). In 92 cases (89%), death occurred outside hospital. The main toxic agents were opiates or opioids (65% of cases), followed by ethanol (9%), tricyclic anti-depressants (TCAs) (4%), benzodiazepines (4%), and zopiclone (4%). Seventy-one (69%) were evaluated as accidental deaths and 32 (31%) as suicides. In 70% of all cases, and in 34% of suicides, the deceased was classified as drug or alcohol dependent. When compared with the 2981 non-fatal acute poisonings registered during the study period, the case fatality rate was 3% (95% C.I., 0.03-0.04). Methanol, TCAs, and antihistamines had the highest case fatality rates; 33% (95% C.I., 0.008-0.91), 14% (95% C.I., 0.04-0.33), and 10% (95% C.I., 0.02-0.27), respectively. Conclusions Three per cent of all acute poisonings were fatal, and nine out of ten deaths by acute poisonings occurred outside hospital. Two-thirds were evaluated as accidental deaths. Although case fatality rates were highest for methanol, TCAs, and antihistamines, most deaths were caused by opiates or opioids.
