The effect of COVID-19 pandemic on the characteristics of patients presenting to the pediatric ocular emergency department in Türkiye: Demographic and diagnoses.

BACKGROUND: This study aims to evaluate how the coronavirus disease 2019 (COVID-19) pandemic has impacted the demographics and diagnoses of patients presenting at a pediatric ophthalmology emergency department (POED) in Türkiye. METHODS: The electronic medical records of patients <18 years old who presented at the POED from March 15 to May 31, 2020 (first stay-at-home period), and from November 15 to December 31, 2020 (second stay-at-home period), were retrospectively scanned. The demographic data and clinical diagnoses from those periods and the same periods in 2019 were compared. RESULTS: No significant differences emerged regarding age (p=0.067) or sex (p=0.268) among the 839 pediatric patients who visited the POED in 2019 (n=510) versus 2020 (n=329). Compared with 2019, 50.63% of fewer patients visited the POED in the first stay-at-home period (i.e., 322 vs. 159) and 9.66% fewer visited in the second period (i.e., 188 vs. 170). The diagnoses in 2019 and 2020 were similar, with foreign body being the most common diagnosis, followed by ocular trauma. CONCLUSION: Amid the COVID-19 pandemic, fewer pediatric patients visited the POED during the first and second stay-at-home periods than during the same periods in 2019, although the difference was less during the second period. Demographic data and diagnoses from year to year, however, were similar. These findings could aid clinicians in developing new strategies and guidelines for POED management in extraordinary situations such as pandemics.

Did the COVID-19 Pandemic Restrict Access to Emergency Urological Services: Assessment of Reorganisation Effectiveness for Hospital Treatment.

Urolithiasis derived renal colic is a common urological condition. If treated properly, the disease resolves without complications; if not treated, it causes infection and renal failure. The COVID-19 restrictions impacted hospitalised treatment of diseases. We analysed the impact of COVID-19 on renal colic treatment at a hospital in Poland. Clinical and demographic data of patients treated during the COVID-19 era were compared with those treated before this pandemic. During the COVID-19 restrictions, renal colic patient hospital admissions fell significantly. However, more patients presented with chronic renal colic symptoms and urinary tract infections. Nevertheless, the degree of hydronephrosis and the number and location of stones did not differ between the two groups. No marked changes were observed in the chosen treatment options. The observed decrease in emergency admissions of patients with acute renal colic with a simultaneous increase in the rate of infectious stones might indicate that some patients requiring urgent medical help did not report to the emergency department or came later than they would before the pandemic, reporting more serious symptoms. One plausible explanation for this may be that the reorganisation of the healthcare system restricted access to urological care. Moreover, some patients may have delayed their visit to the hospital due to the fear of contracting the SARS-CoV-2 coronavirus.

[Using Team Resource Management and Situational Simulation to Improve the Resuscitation Performance Completion Rate].

BACKGROUND & PROBLEMS: Cardiopulmonary resuscitation is an important issue in patient safety. After investigation, we identified the causes of the low rate of resuscitation completion in our emergency department as: incomplete utilization of available first-aid equipment, lack of standards related to task allocation, unclear moving line and instrument placement, lack of teamwork, and poor resuscitation-related communications during the COVID-19 pandemic. PURPOSE: The project aimed to improve the resuscitation performance completion rate. RESOLUTION: The project included designing equipment reminder cards and an airway car, designating specific responsibilities for each team member, establishing standard layouts and traffic flows, and providing situational simulation and team resource management training. RESULTS: After the intervention, the resuscitation performance completion rate had risen to 91.6% from the pre-intervention rate of 69.1%. This has since further risen to a relatively constant completion rate of 98.1%. CONCLUSIONS: The implementation of the team resource management and situational simulation training intervention in our ED improved both the resuscitation completion rate and the rate of return of spontaneous circulation (ROSC).

Effects of the Response to the COVID-19 Pandemic on Assault-Related Head Injury in Melbourne: A Retrospective Study.

Assault is the leading preventable cause of death, traumatic brain injury (TBI), and associated mental health problems. The COVID-19 pandemic has had a profound impact on patterns of interpersonal violence across the world. In this retrospective cross-sectional study, we analysed medical records of 1232 assault victims (domestic violence: 111, random assault: 900, prison assault: 221) with head injuries who presented to the emergency department (ED) at St Vincent's Hospital in Melbourne, Australia, a city with one of the longest and most severe COVID-19 restrictions worldwide. We examined changes in prevalence in the assault group overall and in domestic violence, random assault, and prison assault victims, comparing data from 19.5 months before and after the first day of COVID-19 restrictions in Melbourne. Moreover, we investigated differences driven by demographic factors (Who: age group, sex, and nationality) and clinical variables (Where: assault location, and When: time of arrival to the ED and time from moment of injury until presentation at ED). Descriptive statistics and chi-square analyses were performed. We found the COVID-19 pandemic significantly affected the Where of assault-related TBI, with a shift in the location of assaults from the street to the home, and the increase at home being driven by random assaults on middle-aged adults. Overall, we observed that 86% of the random assault cases were males, whereas 74% of the domestic assault cases were females. Meanwhile, nearly half (44%) of the random assault victims reported alcohol consumption versus a fifth (20%) of domestic violence victims. These findings will have direct implications for developing screening tools and better preventive and ameliorative interventions to manage the sequelae of assault TBI, particularly in the context of future large-scale health crises or emergencies.

Role Delineation of the Code Blue Team: A Quasi-Experimental Study During COVID-19.

INTRODUCTION: The purpose of this study was to assess if implementing a code role delineation intervention in an emergency department would improve the times to defibrillation and medication administration and improve the nurse perception of teamwork. METHODS: A quantitative quasi-experimental study used a retrospective chart review to gather data. A pre- and post-test measured nurse perception of teamwork in a code using the Mayo High Performance Teamwork Scale (MHPTS) after a code role delineation intervention using a paired samples t-test. Pearson r correlations were used to determine relationships between nurse participant (N = 30) demographics and results of the MHPTS scores. RESULTS: A significant increase in teamwork was noted in 5 of the 16 items on the MHPTS regarding improved communication and identified roles in a code: the team leader assures maintenance of an appropriate balance between command authority and team member participation (t = -5.607, P < .001), team members demonstrated a clear understanding of roles (t = -5.415, P < .001), team members repeat back instructions and clarifications to indicate that they heard them correctly (t = -2.400, P = .029), all members of the team are appropriately involved and participate in the activity (t = -2.236, P = .041), and conflicts among team members are addressed without a loss of situation awareness (t = -2.704, P = .016). There was significance between total pre- and post-test scores (t = -3.938, P = .001). DISCUSSION: Implementation of code role delineation identifiers is an effective method of improving teamwork in a code in an emergency department setting.

The Healthcare Relationship during the Second Wave of the COVID-19 Pandemic: A Qualitative Study in the Emergency Department of an Italian Hospital.

The COVID-19 pandemic had an impact not only on people's lives but also on the healthcare system. This study aimed to investigate the healthcare relationship in the Emergency Department (ED) of a hospital in northern Italy, during the second wave of the COVID-19 pandemic. The participants (N = 43) consisted of 16 nurses, 6 doctors from the hospital ED, and 21 patients who accessed this department. Semi-structured interviews were carried out and a thematic analysis was conducted. The findings suggest that the COVID-19 pandemic brought both positive and negative changes to the healthcare relationship that are linked to changes in the organization of the ED and to participants' various experiences of the pandemic. The changes in this relationship should be monitored because they could have long-term effects on healthcare professionals' wellbeing, treatment outcomes, and the healthcare system. The findings from this study could be used to understand these changes and inform intervention strategies to improve the healthcare relationship.

The effect of the COVID-19 pandemic on pediatric asthma-related emergency department visits and hospital admissions in Montréal, Quebec: a retrospective cohort study.

BACKGROUND: Asthma is a chronic respiratory condition that affects 10% of Canadian children and is often exacerbated by viral respiratory infections, prompting concerns about the severity of SARS-CoV-2 disease in children with asthma. We compared sociodemographic and clinical characteristics of children presenting to the emergency department and the incidence of these visits, before and during the pandemic. METHODS: We included children aged 0 to 17 years presenting with asthma to 2 tertiary pediatric emergency departments in Montréal, Quebec, between the prepandemic (Jan. 1, 2017, to Mar. 31, 2020) and pandemic (Apr. 1, 2020, to June 30, 2021) periods. We compared the number of emergency department visits and hospital admissions with an interrupted time series analysis and compared the sociodemographic characteristics based on the Canadian Index of Multiple Deprivation (CIMD) and clinical characteristics (including triage level, intensive care admissions, etc.) with Mann-Whitney and χ2 tests. RESULTS: We examined 22 746 asthma-related emergency department visits. During the pandemic, a greater proportion of patients presented a triage level 1 or 2 (19.3% v. 14.7%) and were admitted to the intensive care unit (2.5% v. 1.3%). The patients' CIMD quintile distributions did not differ between the 2 periods. We found a 47% decrease (relative risk [RR] 0.53, 95% confidence interval [CI] 0.37 to 0.76) in emergency department visits and a 49% decrease (RR 0.51, 95% CI 0.34 to 0.76) in hospital admissions during the pandemic. INTERPRETATION: The decrease in asthma-related emergency department visits was observed through the third wave of the pandemic, but children presented with a higher acuity and with no identified sociodemographic changes. Future studies are required to understand individual behaviours that may have led to the increased acuity at presentation observed in this study.

Evaluation of ABCD2 score during the development of stroke in COVID-19 patients diagnosed with transient ischemic attack in the emergency department.

BACKGROUND: The aim of the present study is to reveal the association between the risk of stroke using ABCD2 score and COVID-19 in patients who presented to our emergency department during the pandemic and were diagnosed with TIA. METHODS: According to the recommendations of the European Stroke Association, patients with an ABCD2 score of <4 were classified as low-risk, and patients with an ABCD2 score of ≥4 were classified as high-risk. Within 90 days of the patient's admission to the emergency room, the development of stroke was tracked and recorded on the system. RESULTS: Stroke occurred in 35.78% of the patients. Regarding COVID-19, 75.34% of stroke patients were positive for COVID-19 and 65.75% had COVID-19 compatible pneumonia on 'thoracic CT'. Regarding mortality, 16.4% of the patients who were positive for COVID-19 and developed a stroke died. The presence of COVID-19 compatible pneumonia on thorax CT, PCR test result and ABCD2 score were determined as independent risk factors for the development of stroke. According to the PCR test results, the probability of having a stroke decreases 0.283 times in patients who are negative for COVID-19. According to the PCR test results, the probability of having a stroke increased 2.7 times in COVID-19 positive patients. CONCLUSIONS: Adding the presence of COVID-19 and the presence of COVID-19 pneumonia to the ABCD2 score, based on the information about the increased risk of stroke in TIA patients, improves the predictive power of the score. More studies are needed in this regard.

Clinical and Forensic Aspects of the Management of Child Abuse: The Experience of the Paediatric Emergency Department in Novara, North-West Italy.

BACKGROUND: Child abuse is an endemic phenomenon that refers to any form of violence aimed at children and adolescents. The Emergency Room is often the entry point to healthcare for the abused child. METHODS: This is a cross-sectional study including minors, aged 0-18 years, of all genders, who experienced any form of violence examined at the Paediatric Emergency Department of the 'Maggiore della Carità' Hospital in Novara (North-West Italy) between 1 January 2017 to 31 December 2021. Data were extrapolated by looking at the diagnosis at discharge. A comparison of the different variables collected was made between the pre-COVID-19 period and the COVID era. RESULTS: 120 minors presented to the paediatric emergency room seeking help for violence. The average age was 10 years, 55% of the victims were male and 75% of them were Italian. In the pre-COVID period, the number of presentations for abuse was 62, while in the COVID period it was 58 with an increase of peer violence (from 38.71% to 62.07%) and with a statistically significant impact of the pandemic on the phenomenon (p-value < 0.00001). In general, peer violence accounts for 50% of the cases reviewed and resulted in fewer reports to the judicial authority and requests for forensic advice. CONCLUSION: The SARS-CoV-2-related pandemic has had an impact on total emergency room admissions and the types of abuse perpetrated.

Telehealth use by walk-in patients who subsequently visited an academic emergency department: a repeated cross-sectional study during the COVID-19 summer 2021.

AIM OF THE STUDY: During the COVID-19 pandemic, telehealth use increased worldwide in a variety of medical specialities and reached new population groups. A baseline survey of telehealth use prior to admission to the emergency department (ED) conducted before COVID-19 concluded that predominantly well-educated men used telehealth. It is unclear how COVID-19 changed the use of telehealth in Swiss emergency patients. We therefore aimed to investigate (i) the frequency of telehealth use during the pandemic, and (ii) how the pandemic has influenced telehealth use and users. MATERIALS AND METHODS: A repeated cross-sectional study was conducted among ED walk-in patients at a tertiary university hospital in Switzerland. The study took place one and a half years after the first confirmed COVID-19 case, during 30 shifts from 8 to 29 July 2021 and compared with the baseline survey conducted in 2019. Eligible patients were questioned about their use of, and attitudes to telehealth. RESULTS: A total of 1020 patients were screened for the COVID survey and 443 complete questionnaires were evaluated. A trend towards a general increase (+6.4%) in telehealth use was demonstrated (50.3%, n = 223 COVID survey vs 43.9%, n = 183 baseline survey; p = 0.058), with a shift to more female patients using telehealth in the COVID survey (female 54.9%, n = 124 vs 45.1%, n = 102; p = 0.052). During the pandemic, first use of telehealth was reported by 12.2% (n = 54) of patients, with a significant increase among patients with low educational status, and the latter patients often indicated that they did not plan to use telehealth after the pandemic. The perceived usefulness of telehealth and adherence to recommendations increased in the COVID survey compared with the baseline survey (adherence 90.3%, n = 149, vs 78.0%, n = 131; p = 0.002). CONCLUSION: We found a trend towards increased use of telehealth among Swiss ED patients. First-time users of telehealth were predominantly less educated and inclusion of these user groups may not be sustainable, as was indicated by the patients. COVID-19 led to greater adherence to telehealth recommendations and higher perceived usefulness. This could be due to the limited access to healthcare providers due to pandemic precautions. When offering telehealth, the needs of all patient groups must be considered, in order to ensure that telehealth provides the greatest benefit with lower barriers to use.

Temporal Trends and Characteristics of Adult Patients in Emergency Department Related to Suicide Attempt or Self-Harm in Korea, 2016-2020.

BACKGROUND: The implementation of an effective suicide prevention program requires the identification and monitoring of subpopulations with elevated risks for suicide in consideration of demographic characteristics, to facilitate the development of tailored countermeasures for tackling the risk factors of suicide. We examined the annual trends in emergency department (ED) visits for suicide attempts (SAs) or self-harm and investigated the sex- and age-specific characteristics of individuals who visited the ED for SA and self-harm. METHODS: Data on ED visits for SAs or self-harm in Korea from 2016 to 2020 were extracted from the National Emergency Department Information System and assessed. We evaluated the age-standardized incidence rate of ED visits for SAs or self-harm, and hospital mortality among individuals who visited the ED for SAs or self-harm. In addition, the characteristics of the individuals were compared according to sex and age. RESULTS: We identified 145,963 ED visits for SAs or self-harm (0.42% of the total ED visits) during the study period. The rate of ED visits increased in the youngest age group (19-29 years old), and was more prominent among women (increased by an annual average of 22.5%), despite the coronavirus disease pandemic. The middle-aged group (45-64 years old) had a higher rate of mortality than other age groups, and the highest proportion of individuals on Medical Aid. CONCLUSION: It is necessary to plan age- and gender-specific suicide prevention programs that focus on improving the limited public mental health resources for the vulnerable populations.

Effects of the COVID-19 pandemic on nurses' psychological well being in an emergency room.

OBJECTIVES: to assess the level of anxiety of nurses in an emergency room in view of the new Coronavirus and describe the relationship between the degrees of anxiety and their sociodemographic variables. METHODS: quantitative descriptive-correlational study with a sample of 60 nurses. A questionnaire was used as a data collection instrument based on the Hamilton Anxiety Assessment Scale. RESULTS: the nurses' average anxiety is mild. A statistically significant relationship was found between anxiety and the variables "sex" and "children", with women having higher levels of anxiety than men, and nurses who do not have children showing mild, moderate, or severe anxiety. CONCLUSIONS: COVID-19 triggers anxiety in nurses, sometimes at pathological levels. Being female and not having children increase the anxiety experienced. Sex can be considered the determining factor for the level of anxiety experienced.

Review article: Roles of activities of daily living and frailty assessments for residents of residential aged care services in emergency department transfers: A scoping review.

Residents from residential aged care services (RACS) (i.e. nursing homes) many of whom are frail or disabled, are frequently transferred to ED for treatment of acute episodes of illness or injury. This review scoped the research related to the ways in which frailty or activities of daily living (ADL) measures are used for clinical purposes, either prior to the transfer of patients to ED or in ED themselves. A search for original studies up to June 2021 that included participants aged 65 years or over was conducted across four databases. Abstracts were first reviewed, leading to full text screening and article selection. Thirty-four studies were included in the scoping review. Most of the ADL and frailty assessments were conducted in residential aged care settings. In seven studies, ADL or frailty assessments in the aged care setting contributed to reduced transfer rates to ED. No results were found that associated the assessment of ADL or frailty with decisions related to treatment in the ED. A single ED study involved specialist emergency nursing in an ED as an intervention which included frailty assessment and led to decreased hospitalisation. This scoping review confirms an opportunity for further research into the ways frailty and ADL assessments are used for decision making in relation to the transfer of frail older people to ED, including how these assessments influence their treatment.

The dental triage method at Rothschild Hospital during the first lockdown due to the COVID-19 pandemic.

OBJECTIVE: This study aims to (1) assess the efficacy of a face-to-face emergency protocol in children and adults and (2) measure the efficacies of prediagnosis at the triage level and clinical diagnosis at the emergency department level during the COVID-19 pandemic. METHODS: A triage protocol was applied for patients at the entry of the Rothschild Hospital (AP-HP) between March 18th and May 11th, 2020. First, patients underwent a triage based on self-reported symptoms. If their condition was deemed urgent, they were oriented toward dental professionals, who performed an intraoral examination leading to a clinical diagnosis. Triage and diagnoses were categorized into four emergency groups: infectious, prosthetic, traumatic, and others. The agreement between triage and clinical diagnosis was tested (χ2 test). Positive predictive value (PPV), negative predictive value (NPV), sensitivity, and specificity for each diagnostic category were assessed to evaluate the performance and efficacy of the triage. RESULTS: Out of 1562 dental visits, 1064 were included in this analysis. The most frequently reported symptoms by children at triage were pain (31.5%) and trauma (22%). Adults mainly complained of abscesses (45.1%) and pulpitis (20.5%). The most frequent clinical diagnoses were abscesses (29.2%) and pulpitis (20.5%) among children and adults, respectively. Tooth extraction was the most frequent treatment modality. Systemic antibiotics were prescribed for 49.2% of patients. Regardless of the age class, the PPV was high for groups 1 to 3, ranging from 78.9% to 100%. The NPV was high in all groups, ranging from 68.8% to 99.1%. CONCLUSION: This study demonstrates that the triage implanted during the first COVID-19 lockdown was effective and is an appropriate tool for the referral of adults and children before clinical examination.

Pediatric emergency department physicians' perceptions of virtual mental health assessments for urgent needs.

PURPOSE: Pressures related to the COVID-19 pandemic have created the need to develop innovative ways to deliver mental health care, especially for urgent needs. After the launch of a pediatric Emergency Department (ED) Virtual Care service, we aimed to evaluate pediatric ED physicians' experiences with the use of ED virtual care for mental health assessments. METHODS: This mixed-methods study was conducted at a pediatric academic health center in Ontario, Canada. Pediatric ED physicians who conducted ED virtual mental health assessments from May to December 2020 were eligible. Participants completed a 22-question novel survey and were invited to participate in a focus group. Descriptive and thematic analyses were used to analyze the data. RESULTS: Twenty-nine physicians provided mental health services through the ED virtual care platform. Twenty-five physicians (86% response rate) completed the survey and 3 (10%) participated in a focus group. While many agreed that virtual care benefits patients (67%), key barriers identified included time constraints, lack of mental health clinician support, and uncertainty around the pediatric ED physicians' role in these types of assessments. Despite these barriers, physicians recognized the potential benefit of the ED virtual care service for mental health assessments and were largely amenable to improving this process should mental health support be available. CONCLUSIONS: While many physicians agreed that there is a potential benefit of the ED virtual care platform for urgent mental health assessments, time constraints and lack of confidence in providing satisfactory virtual mental health care with minimal mental health support limited its acceptability. These findings can inform the future implementation of mental health services using an innovative virtual ED platform.

RéSUMé: OBJECTIF: Les pressions liées à la pandémie de COVID-19 ont créé le besoin de développer des moyens innovants pour fournir des soins de santé mentale, en particulier pour les besoins urgents. Après le lancement d'un service de soins virtuels aux urgences pédiatriques, nous avons cherché à évaluer les expériences des médecins des urgences pédiatriques avec l'utilisation des soins virtuels aux urgences pour les évaluations de la santé mentale. MéTHODOLOGIE: Cette étude à méthodes mixtes a été menée dans un centre universitaire de santé pédiatrique en Ontario, au Canada. Les médecins pédiatriques qui ont effectué des évaluations virtuelles de la santé mentale aux urgences de mai à décembre 2020 étaient admissibles. Les participants ont rempli une enquête inédite de 22 questions et ont été invités à participer à un groupe de discussion. Des analyses descriptives et thématiques ont été utilisées pour analyser les données. RéSULTATS: Vingt-neuf médecins ont fourni des services de santé mentale par le biais de la plateforme de soins virtuels des urgences. Vingt-cinq médecins (taux de réponse de 86 %) ont répondu au sondage et trois (10 %) ont participé à un groupe de discussion. Si beaucoup s'accordent à dire que les soins virtuels sont bénéfiques pour les patients (67 %), les principaux obstacles identifiés sont les contraintes de temps, le manque de soutien des cliniciens en santé mentale et l'incertitude quant au rôle des urgentistes pédiatriques dans ces types d'évaluations. Malgré ces obstacles, les médecins ont reconnu l'avantage potentiel du service de soins virtuels de l'urgence pour les évaluations de la santé mentale et étaient largement disposés à améliorer ce processus si un soutien en santé mentale était disponible. CONCLUSIONS: Bien que de nombreux médecins s'accordent à dire que la plateforme de soins virtuels des urgences présente un avantage potentiel pour les évaluations urgentes de la santé mentale, les contraintes de temps et le manque de confiance dans la prestation de soins de santé mentale virtuels satisfaisants avec un soutien minimal en matière de santé mentale ont limité son acceptabilité. Ces résultats peuvent éclairer la mise en œuvre future des services de santé mentale à l'aide d'une plateforme virtuelle d'urgence innovante.

Single-Center Experience in Detecting Influenza Virus, RSV and SARS-CoV-2 at the Emergency Department.

Reverse transcription polymerase chain reaction (RT-PCR) on respiratory tract swabs has become the gold standard for sensitive and specific detection of influenza virus, respiratory syncytial virus (RSV) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In this retrospective analysis, we report on the successive implementation and routine use of multiplex RT-PCR testing for patients admitted to the Internal Medicine Emergency Department (ED) at a tertiary care center in Western Austria, one of the hotspots in the early coronavirus disease 2019 (COVID-19) pandemic in Europe. Our description focuses on the use of the Cepheid® Xpert® Xpress closed RT-PCR system in point-of-care testing (POCT). Our indications for RT-PCR testing changed during the observation period: From the cold season 2016/2017 until the cold season 2019/2020, we used RT-PCR to diagnose influenza or RSV infection in patients with fever and/or respiratory symptoms. Starting in March 2020, we used the RT-PCR for SARS-CoV-2 and a multiplex version for the combined detection of all these three respiratory viruses to also screen subjects who did not present with symptoms of infection but needed in-hospital medical treatment for other reasons. Expectedly, the switch to a more liberal RT-PCR test strategy resulted in a substantial increase in the number of tests. Nevertheless, we observed an immediate decline in influenza virus and RSV detections in early 2020 that coincided with public SARS-CoV-2 containment measures. In contrast, the extensive use of the combined RT-PCR test enabled us to monitor the re-emergence of influenza and RSV detections, including asymptomatic cases, at the end of 2022 when COVID-19 containment measures were no longer in place. Our analysis of PCR results for respiratory viruses from a real-life setting at an ED provides valuable information on the epidemiology of those infections over several years, their contribution to morbidity and need for hospital admission, the risk for nosocomial introduction of such infection into hospitals from asymptomatic carriers, and guidance as to how general precautions and prophylactic strategies affect the dynamics of those infections.

The COVID-19 impact and characterization on substance use-related emergency department visits for adolescents and young adults in Canada: Practical implications.

RATIONALE: Coronavirus (COVID-19)-related stressors precipitated the mental health crisis and increased substance use in Canada and worldwide. As the pandemic continues to evolve, monitoring and updating substance use-related ED visit trends is essential to ensure the stability and quality of ED services under the prolonged pandemic timeline. AIMS AND OBJECTIVES: This study examined the trends and characterization of substance use-related ED visits during the pandemic among adolescents and young adults (aged 13-25 years) in Ontario, Canada. METHODS: Descriptive statistics and binary logistic regression analyses were conducted using population-based, repeated cross-sectional data. The volume, patient characteristics (age and sex) and hospital/ED visit features (triage to end time, timing of the visit, triage level and referral source) were compared before (2019) and during COVID-19 (2020 and 2021) by each substance type (alcohol, opioid, cannabis, sedatives, cocaine, stimulants and multiple psychoactive substances). RESULTS: Substance use-related ED visits decreased by 1.5 times during the pandemic compared to the prepandemic level. However, opioid-related ED visits continued to show an increasing trend and did not recover to the prepandemic level in 2021. Moreover, a significant increase in emergent/life-threatening triage levels (Canadian Triage and Acuity Scales 1 and 2) in substance-related ED visits is alarming (2019 = 36.8%, 2020 = 38.7% and 2021 = 38.4%). We also found a general decrease in weekend visits, overnight visits and visits on statutory holidays, and substance use-related ED patients tended to stay longer (over 6 h) in the ED during the pandemic. CONCLUSION: Our findings indicate unmet substance use treatment needs due to the limited accessibility and heightened threshold for ED visits during the pandemic. Providing access to substance treatment/programs outside ED is critical to reducing substance use-related complications presenting in the ED. Also, policies addressing the pandemic-related complexities in the ED and Health Human Resource challenges are warranted.
