Emergency Department visits due to intoxications in a Dutch university hospital: Occurrence, characteristics and health care costs

The PIRATE mnemonic: providing a structured approach in the care for intoxicated patients at the emergency department

BACKGROUND

Expertise in toxicology is essential for acute care providers, as intoxicated patients frequently present to Emergency Departments. These patients can be challenging for care providers because they often present with uncertain substance exposure and unknown dose and timing of these exposures.

METHODS

The Dutch Society of Emergency Physicians has developed an mnemonic to support treating physicians in a structured approach for the management of (undifferentiated) intoxicated patients.

RESULTS

The PIRATE mnemonic was developed, which includes the following aspects and sequence of care for the intoxicated patient: primary survey, investigation & identification, risk assessment, ADME (comprising pharmacokinetic therapeutic targets: absorption, distribution, metabolism, elimination), therapy and evaluation.

CONCLUSION

The toxicology section of the Dutch Society of Emergency Physicians developed the PIRATE mnemonic to provide a structured approach in the management of patients presenting with acute intoxications to Emergency Departments. It summarizes the essential steps and priorities required in the care of intoxicated patients. Further, it provides a common strategy for all specialties involved in the care of the acutely intoxicated patient, contributing to developing greater competence in poisoning management.

Screening for hazardous alcohol use in the Emergency Department: Comparison of phosphatidylethanol with the Alcohol Use Disorders Identification Test and the Timeline Follow-back

BACKGROUND

Up to 15% of all visits to the Emergency Department (ED) are alcohol related. Identification of problematic alcohol use is important in this setting because it allows for intervention and prevention efforts. This study investigated the correlation between the objective phosphatidylethanol (PEth) marker and the subjective Alcohol Use Disorders Identification Test (AUDIT) and Timeline Followback Questionnaire (TLFB) as screening methods for hazardous alcohol use in the general ED population.

METHODS

This prospective cohort study included 301 ED patients (57% male) who were seen in the ED and required to give a blood sample. The correlation between the values of PEth (PEth 16:0/18:1 and PEth 16:0/18:2) and the scores on the AUDIT and TLFB were analyzed using Spearman's rank correlation coefficient. Differences between risk categories of PEth and AUDIT were also examined.

RESULTS

The Spearman correlation coefficients between PEth 16:0/18:1|PEth 16:0/18:2 values and the AUDIT scores were moderate (PEth 16:0/18:1: 0.67, p < 0.001; PEth 16:0/18:2: 0.67, p < 0.001). Of the patients who scored 'low risk drinking/abstinence' according to the AUDIT questionnaire, respectively 1% and 4% had PEth 16:0/18:1|PEth 16:0/18:2 values indicating excessive alcohol use, and another 10% and 12% had PEth 16:0/18:1|PEth 16:0/18:2 values indicating moderate alcohol consumption. Of the 12 (PEth 16:0/18:1) and 25 (PEth 16:0/18:2) patients with high-risk values, respectively 25% and 40% scored in the lowest risk category on the AUDIT questionnaire. Spearman correlation coefficients between PEth 16:0/18:1|PEth 16:0/18:2 values and TLFB two-week scores were high (PEth 16:0/18:1: 0.74, p < 0.001; PEth 16:0/18:2: 0.82, p < 0.001).

CONCLUSIONS

AUDIT scores were moderately correlated with PEth values in the general ED population. In almost all cases where there was not a good correlation, patients had high PEth values with low AUDIT scores. We conclude that PEth identifies patients with problematic alcohol use who are missed by the AUDIT questionnaire and therefore PEth could be used as an additional screening method for hazardous alcohol use in this population.

Impact of co-ingestion of ethanol on the clinical symptomatology and severity of patients attended in the emergency department for recreational drug toxicity

OBJECTIVE

Investigate whether there are differences in the drugs involved, symptomatology and severity of drug intoxication in patients with co-ingestion of alcohol attended in hospital emergency departments (ED).

METHOD

Patients attended in 11 Spanish EDs due to drug intoxication were included. Sociodemographic and clinical characteristics were collected. A combined adverse event of cardiorespiratory arrest, need for intubation, and admission to intensive care or death was considered as the primary indicator of severity. The symptomatology and severity were compared adjusted for age, sex and type of drug based on whether or not ethanol had been co-ingested.

RESULTS

3925 patients (alcohol co-ingestion: 2290, 58.3%) with a mean age of 33 (±11) years were included, and 25% were women. Co-ingestion of alcohol was observed in younger patients, in EDs in areas with high leisure tourism, on holidays and during the early morning hours. It was also more frequent in individuals intoxicated by amphetamine derivatives (66.2%) and cocaine (65.7%), and was more frequently associated with a reduction in consciousness (odds ratio [OR] = 2.13, 95% confidence interval [CI] 1.69-2.67) and agitation/aggressiveness (OR = 1.22, 95% = 1.04-1.43). A combined adverse event was observed in 114 patients (2.9%) with no differences between individuals co-ingesting or not ethanol (3.1% vs. 2.7%; OR = 1.11, 95% CI = 0.74-1.65).

CONCLUSION

Co-ingestion of alcohol is more frequent in individuals intoxicated by cocaine and amphetamines and predisposes a greater reduction in the level of consciousness or agitation, although there are no differences in the severity of the episodes of drug intoxication.

The 12 -year evolution of emergency department alcohol-related admissions in a student city

OBJECTIVE

To investigate the trends in incidence of alcohol-intoxicated patients who present at the emergency department (ED), as well as the characteristics of these patients.

METHODS

Retrospective observational study based on data collected from 2008 until 2019 in two EDs in Leuven, Belgium. As a routine ED procedure, a blood alcohol concentration (BAC) test is ordered for all patients suspected of alcohol use as a primary presenting sign. Patients older than 10 years of age with a BAC ≥ 0.1 g/L were included. BAC levels, age, gender and proportion of repeat admissions were analysed.

RESULTS

The absolute number of patients with a positive BAC test increased from 1260 in 2008 to 1908 in 2019 (51.4%). Male-to-female ratio remained stable (2:1). In the University Hospital Leuven , the most represented age group shifted from 20-29 and 40-49 year olds (2008) to 50-59 year olds (2019). The most common age groups in Heilig Hart Leuven were 10-19 year olds and 20-29 year olds, which remained stable over the study period. The readmission rate was 18% within the entire study period with a range of 2 to 46 times.

CONCLUSION

Our study showed an annual increase in alcohol-related admissions. The highest rates of alcohol-related ED visits occurred in the age group 50-59. Patients with a repeat admission accounted for a large number of the total alcohol-related visits, placing a major burden on our healthcare system. It will be a challenge to timely detect patients at risk, regardless of their age, to prevent future ED admissions.

Predictors of clinical severity in subjects attending the Emergency Department for substance use: a ten-year cross-sectional study

OBJECTIVE

Substance-related referrals to the Emergency Department (ED) are rising. Multiple substance use is frequent, and psychiatric patients represent a high-risk population. Our study aimed at identifying risk factors for increased severity in ED attendances for substance use.

METHODS

We retrospectively evaluated consecutive patients attending the ED over ten years for substance-related problems, subdivided according to the triage code as having a life-threatening (LT), potentially life-threatening (P-LT), and non-life-threatening (N-LT) condition.

RESULTS

Substance/drug intake for deliberate self-harm was a risk factor for being classified as LT compared to both P-LT (OR = 6.357; p ≤ 0.001) and N-LT (OR = 28.19; p ≤ 0.001). Suicide attempts (OR = 4.435; p = 0.022) and multiple substance use (OR = 1.513; p = 0.009) resulted as risk factors for P-LT, compared to N-LT. Psychiatric diagnosis (OR = 1.942; p = 0.042) and multiple substance use (OR = 1.668; p = 0.047) were risk factors for being classified as LT rather than N-LT.

CONCLUSIONS

In our sample, self-harming overdoses were the strongest risk factor for highest overall severity in a real-world setting. Psychiatric disorders and multiple substance use also increased the risk for greater severity at presentation. Substance use worsens patients' clinical picture and management, suggesting the need for consultation-liaison psychiatry services in emergency contexts and highlighting the role of EDs as key sites for identification and early intervention.

Risk Management in First Aid for Acute Drug Intoxication

Drug abuse (cannabis, cocaine, opiates, and synthetic drugs) is an increasing phenomenon, especially in the younger population, thus leading to more cases of intoxication requiring evaluation in the emergency department and subsequent hospitalization. In 2017, 34.2% of students reported having used an illegal psychoactive substance in their lifetime, while 26% reported having done so over the past year. We made a review about the effectiveness of the role of the temporary observation unit in the emergency department to improve management of acute drugs intoxication. We checked medical literature from the last 10 years (2009-2019). The following electronic databases were systematically searched: MEDLINE-PubMed, Web of Science, Scopus, and the Cochrane Central Register of Controlled Trials. Then, a systematic review was carried out according to the Preferred Reporting Items for Systematic Review standards. Intoxicated patients usually display a favorable medical course, few diagnostic and therapeutic interventions, a short stay in the hospital, and, when hospitalization is needed, semi-intensive therapy is a feasible solution; therefore, intoxicated patients are ideal candidates for a temporary observation unit. The emergency department is very important to manage intoxicated patients; however, the hospitalization of these patients is often not necessary.
