Leaving emergency departments without completing treatment among First Nations and non-First Nations patients in Alberta: a mixed-methods study.

BACKGROUND: Our previous research showed that, in Alberta, Canada, a higher proportion of visits to emergency departments and urgent care centres by First Nations patients ended in the patient leaving without being seen or against medical advice, compared with visits by non-First Nations patients. We sought to analyze whether these differences persisted after controlling for patient demographic and visit characteristics, and to explore reasons for leaving care. METHODS: We conducted a mixed-methods study, including a population-based retrospective cohort study for the period of April 2012 to March 2017 using provincial administrative data. We used multivariable logistic regression models to control for demographics, visit characteristics, and facility types. We evaluated models for subgroups of visits with pre-selected illnesses. We also conducted qualitative, in-person sharing circles, a focus group, and 1-on-1 telephone interviews with health directors, emergency care providers, and First Nations patients from 2019 to 2022, during which we reviewed the quantitative results of the cohort study and asked participants to comment on them. We descriptively categorized qualitative data related to reasons that First Nations patients leave care. RESULTS: Our quantitative analysis included 11 686 287 emergency department visits, of which 1 099 424 (9.4%) were by First Nations patients. Visits by First Nations patients were more likely to end with them leaving without being seen or against medical advice than those by non-First Nations patients (odds ratio 1.96, 95% confidence interval 1.94-1.98). Factors such as diagnosis, visit acuity, geography, or patient demographics other than First Nations status did not explain this finding. First Nations status was associated with greater odds of leaving without being seen or against medical advice in 9 of 10 disease categories or specific diagnoses. In our qualitative analysis, 64 participants discussed First Nations patients' experiences of racism, stereotyping, communication issues, transportation barriers, long waits, and being made to wait longer than others as reasons for leaving. INTERPRETATION: Emergency department visits by First Nations patients were more likely to end with them leaving without being seen or against medical advice than those by non-First Nations patients. As leaving early may delay needed care or interfere with continuity of care, providers and departments should work with local First Nations to develop and adopt strategies to retain First Nations patients in care.

Exploring paramedic care for First Nations in Alberta: a qualitative study.

BACKGROUND: Prior work has shown that a greater proportion of First Nations patients than non-First Nations patients arrive by ambulance to emergency departments in Alberta. The objective of this study was to understand First Nations perspectives on transitions in care involving paramedics, and paramedic perspectives on serving First Nations communities. METHODS: Participants for this participatory qualitative study were selected by means of purposive sampling through author networks, established relationships and knowledge of the Alberta paramedicine system. First Nations research team members engaged First Nations community organizations to identify and invite First Nations participants. Four sharing circles were held virtually in July 2021 via Zoom by the Alberta First Nations Information Governance Centre. We analyzed the data from the sharing circles using a Western thematic approach. The data were reviewed by Indigenous researchers. RESULTS: Forty-four participants attended the 4 sharing circles (8-14 participants per circle), which ranged from 68 to 88 minutes long. We identified 3 major themes: racism, system barriers and solutions. First Nations participants described being stereotyped as misusing paramedic systems and substance using, which led to racial discrimination by paramedics and emergency department staff. Discrimination and lack of options to return home after care sometimes led First Nations patients to avoid paramedic care, and lack of alternative care options drove patients to access paramedic care. First Nations providers described facing racism from colleagues and completing additional work to act as cultural mentors to non-First Nations providers. Paramedics expressed moral distress when called on to handle issues outside their scope of practice and when they observed discrimination that interfered with patient care. Proposed solutions included First Nations self-determination in paramedic service design, cultural training and education for paramedics, and new paramedicine service models. INTERPRETATION: First Nations people face discrimination and systemic barriers when accessing paramedicine. Potential solutions include the integration of paramedics in expanded health care roles that incorporate First Nations perspectives and address local priorities, and First Nations should lead in the design of and priority setting for paramedic services in their communities.

Transitions in health care settings for frequent and infrequent users of emergency departments: a population-based retrospective cohort study.

BACKGROUND: Efforts to reduce emergency department (ED) volumes often target frequent users. We examined transitions in care across ED, hospital, and community settings, and in-hospital death, for high system users (HSUs) compared to controls. METHODS: Population-based databases provided ED visits and hospitalizations in Alberta and Ontario, Canada. The retrospective cohort included the top 10% of all the ED users during 2015/2016 (termed HSUs) and a random sample of controls (4 per each HSU) from the bottom 90% per province. Rates of transitions among ED, hospitalization, community settings, and in-hospital mortality were adjusted for sociodemographic and ED variables in a multistate statistical model. RESULTS: There were 2,684,924 patients and 579,230 (21.6%) were HSUs. Patient characteristics associated with shorter community to ED transition times for HSUs included Alberta residence (ratio of hazard ratio [RHR] = 1.11, 95% confidence interval [CI] 1.11,1.12), living in areas in the lower income quintile (RHR = 1.06, 95%CI 1.06,1.06), and Ontario residents without a primary health care provider (RHR = 1.13, 95%CI 1.13,1.14). Once at the ED, characteristics associated with shorter ED to hospital transition times for HSUs included higher acuity (e.g., RHR = 1.70, 95% CI 1.61, 1.81 for emergent), and for many diagnoses including chest pain (RHR = 1.71, 95%CI 1.65,1.76) and gastrointestinal (RHR = 1.66, 95%CI 1.62,1.71). Once admitted to hospital, HSUs did not necessarily have longer stays except for conditions such as chest pain (RHR = 0.90, 95% CI 0.86, 0.95). HSUs had shorter times to death in the ED if they presented for cancer (RHR = 2.51), congestive heart failure (RHR = 1.93), myocardial infarction (RHR = 1.53), and stroke (RHR = 1.84), and shorter times to death in-hospital if they presented with cancer (RHR = 1.29). CONCLUSIONS: Differences between HSUs and controls in predictors of transitions among care settings were identified. Co-morbidities and limitations in access to primary care are associated with more rapid transitions from community to ED and hospital among HSUs. Interventions targeting these challenges may better serve patients across health systems.. TRIAL REGISTRATION: Not applicable.

Incidence of Pressure Injury Among Older Adults Transitioning from Long-term Care to the ED.

OBJECTIVE: To identify sociodemographic, health condition, and organizational/process factors associated with pressure injury (PI) incidence during older adults' emergency transitions from long-term care (LTC) to the ED. METHODS: Emergency transitions were tracked for older adults within included LTC facilities to participating EDs in two urban centers located in provinces in Canada. Binary logistic regression was used to examine the influence of sociodemographic, service use, and client health and function factors on the incidence of PIs during transitions from LTC facilities to EDs. RESULTS: Having a mobility issue (odds ratio [OR], 4.318; 95% CI, 1.344-13.870), transitioning from a publicly owned versus a nonprofit volunteer LTC facility (OR, 4.886; 95% CI, 1.157-20.634), and time from ED arrival to return to LTC being 7 to 9 days (OR, 41.327; 95% CI, 2.691-634.574) or greater than 9 days (OR, 77.639; 95% CI, 5.727-1,052.485) significantly increased the odds of experiencing a new skin injury upon return to LTC. A higher number of reported reasons for emergency transition (up to 4) significantly decreased the odds of a new PI upon return to LTC (OR, 0.315; 95% CI, 0.113-0.880). CONCLUSIONS: The study findings can be used to identify LTC residents at increased risk for developing new skin injuries during an emergency transition, namely, those with mobility impairment, those requiring inpatient care for 6 or more days, and those transitioning from publicly owned LTC facilities. Evaluating the uptake and effectiveness of single-pronged and multipronged interventions such as visual cues for patient turning through online monitoring, consistent risk assessments, and improved nutrition in all care settings are vital next steps in preventing skin injuries in this population.

Action, Accountability and Transparency for Indigenous Health Systems Safety.

Anti-Indigenous racism is prevalent in Canada, especially within healthcare systems. Consequences are catastrophic, including deaths of Indigenous patients. Systems change and critical education guided by the Indigenous Peoples and research into how racism operates within healthcare settings are needed. In Alberta, promising initiatives are under way, including a First Nations-led initiative identifying racism and colonialism as key health determinants, novel experiential education, transformative education for senior health leaders and reframing health system measures to reflect Indigenous Peoples' perspectives. The time is now for comprehensive action toward eliminating racism within healthcare systems and fostering Indigenous health systems safety. Indigenous lives depend on it.

Buprenorphine/naloxone initiation and referral as a quality improvement intervention for patients who live with opioid use disorder: quantitative evaluation of provincial spread to 107 rural and urban Alberta emergency departments.

OBJECTIVES: Opioid use disorder is a major public health concern that accounts for a high number of potential years of life lost. Buprenorphine/naloxone is a recommended treatment for opioid use disorder that can be started in the emergency department (ED). We developed an ED-based program to initiate buprenorphine/naloxone for eligible patients who live with opioid use disorder, and to provide unscheduled, next-day follow-up referrals to an opioid use disorder treatment clinic (in person or virtual) for continuing patient care throughout Alberta. METHODS: In this quality improvement initiative, we supported local ED teams to offer buprenorphine/naloxone to eligible patients presenting to the ED with suspected opioid use disorder and refer these patients for follow-up care. Process, outcome, and balancing measures were evaluated over the first 2 years of the initiative (May 15, 2018-May 15, 2020). RESULTS: The program was implemented at 107 sites across Alberta during our evaluation period. Buprenorphine/naloxone initiations in the ED increased post-intervention at most sites with baseline data available (11 of 13), and most patients (67%) continued to fill an opioid agonist prescription at 180 days post-ED visit. Of the 572 referrals recorded at clinics, 271 (47%) attended their first follow-up visit. Safety events were reported in ten initiations and were all categorized as no harm to minimal harm. CONCLUSIONS: A standardized provincial approach to initiating buprenorphine/naloxone in the ED for patients living with opioid use disorder was spread to 107 sites with dedicated program support staff and adjustment to local contexts. Similar quality improvement approaches may benefit other jurisdictions.

ABSTRAIT: OBJECTIFS: Le trouble lié à la consommation d'opioïdes est une préoccupation majeure en santé publique qui explique le nombre élevé d'années potentielles de vie perdues. La buprénorphine/naloxone est un traitement recommandé pour le trouble lié à l'utilisation d'opioïdes qui peut être commencé au service des urgences (SU). Nous avons mis au point un programme axé sur les urgences pour commencer la buprénorphine/naloxone pour les patients éligibles qui vivent avec un trouble lié à l'utilisation d'opioïdes, et pour fournir suivis des cas référés le jour suivant vers une clinique de soins des troubles liés à l'utilisation d'opioïdes (sur place ou virtuelle) pour les soins continus aux patients partout en Alberta. MéTHODES: Dans le cadre de cette initiative d'amélioration de la qualité, nous avons aidé les équipes locales de SU à offrir la buprénorphine/naloxone aux patients admissibles qui se présentent à la SU avec un trouble présumé de consommation d'opioïdes et à les diriger vers des soins de suivi. Le processus, les résultats et les mesures d'équilibre ont été évalués au cours des deux premières années de l'initiative (du 15 mai 2018 au 15 mai 2020). RéSULTATS: Le programme a été mis en œuvre dans 107 sites en Alberta pendant notre période d'évaluation. Les initiations à la buprénorphine/naloxone à l'urgence ont augmenté après l'intervention dans la plus grande partie de sites pour lesquels des données de référence étaient disponibles (11 sur 13), et la plupart des patients (67 %) ont continué de remplir une ordonnance d'agonistes opioïdes 180 jours après la visite à l'urgence. Sur les 572 renvois enregistrés aux cliniques, 271 (47 %) ont assisté à leur première visite de suivi. Des événements liés à la sécurité ont été signalés dans 10 initiatives et ont tous été classés comme n'ayant causé aucun conséquences à des conséquences minimes. CONCLUSIONS: Une approche provinciale standardisé de lancement de la buprénorphine/naloxone à l'urgence pour les patients atteints d'un trouble lié à la consommation d'opioïdes a été diffusée à 107 sites à l'aide de soutien aux programmes spécialisé et des ajustements aux contextes locaux. Des approches semblables d'amélioration de la qualité pourraient profiter à d'autres juridictions.

A first look at consistency of documentation across care settings during emergency transitions of long-term care residents.

BACKGROUND: Documentation during resident transitions from long-term care (LTC) to the emergency department (ED) can be inconsistent, leading to inappropriate care. Inconsistent documentation can lead to undertreatment, inefficiencies and adverse patient outcomes. Many individuals residing in LTC have some form of cognitive impairment and may not be able to advocate for themselves, making accurate and consistent documentation vital to ensuring they receive safe care. We examined documentation consistency related to reason for transfer across care settings during these transitions. METHODS: We included residents of LTC aged 65 or over who experienced an emergency transition from LTC to the ED via emergency medical services. We used a standardized and pilot-tested tracking tool to collect resident chart/patient record data. We collected data from 38 participating LTC facilities to two participating EDs in Western Canadian provinces. Using qualitative directed content analysis, we categorized documentation from LTC to the ED by sufficiency and clinical consistency. RESULTS: We included 591 eligible transitions in this analysis. Documentation was coded as consistent, inconsistent, or ambiguous. We identified the most common reasons for transition for consistent cases (falls), ambiguous cases (sudden change in condition) and inconsistent cases (falls). Among inconsistent cases, three subcategories were identified: insufficient reporting, potential progression of a condition during transition and unclear reasons for inconsistency. CONCLUSIONS: Shared continuing education on documentation across care settings should result in documentation supports geriatric emergency care; on-the-job training needs to support reporting of specific signs and symptoms that warrant an emergent response, and discourage the use of vague descriptors.

Impacts of racism on First Nations patients' emergency care: results of a thematic analysis of healthcare provider interviews in Alberta, Canada.

BACKGROUND: First Nations people experience racism in society and in the healthcare system. This study aimed to document emergency care providers' perspectives on care of First Nations patients. First Nations research partner organizations co-led all aspects of the research. METHODS: Sixteen semi-structured interviews were conducted with Alberta emergency department (ED) physicians and nurses between November 2019 and March 2020. RESULTS: ED providers reported that First Nations patients are exposed to disrespect through tone and body language, experience overt racism, and may be neglected or not taken seriously. They described impacts of racist stereotypes on patient care, and strategies they took as individuals to address patient barriers to care. Recognized barriers to care included communication, resources, access to primary care and the ED environment itself. CONCLUSIONS: Results may inform the content of anti-racist and anti-colonial pedagogy that is contextually tailored to ED providers, and inform wider systems efforts to counter racism against First Nations members and settler colonialism within healthcare.

Age-varying effects of repeated emergency department presentations for children in Canada.

OBJECTIVES: Repeated presentations to emergency departments (EDs) may indicate a lack of access to other health care resources. Age is an important predictor of frequent ED use; however, age-varying effects are not generally investigated. This study examines the age-specific effects of predictors on ED presentation frequency for children in Alberta and Ontario, Canada. METHODS: This retrospective study used population-based data during April 2010 to March 2017. Data were extracted from the National Ambulatory Care Reporting System for children aged <18 who were members of the top 10% of ED users in any one of the fiscal years 2011/2012 to 2015/2016 along with a comparison sample from the bottom 90%. A marginal regression model studied the age-varying associations on the frequency of ED presentations with province, sex, access to primary health care provider (for Ontario only), area of residence and lowest neighbourhood income quintile. RESULTS: There were 2,481,172 patients who made 9,229,156 ED presentations. The effects of sex, lowest income quintile, rural residence, access to primary health care provider and province on the frequency of presentations varied by age. Notably, boys go from having more frequent presentations than girls when aged ≤5 (i.e. adjusted intensity ratio [IR]=1.04 at age 5, 95% confidence interval [CI] = 1.03,1.06) to less frequent for ages 8-11 years and beyond 14 (i.e. IR = 0.80 at age 15, 95% CI = 0.78,0.81). Adolescents aged ≥15 without access to a primary care provider had more frequent presentations compared to those with a primary care provider. CONCLUSIONS: When examining the frequency of ED presentations in children, age-varying effects of predictors should be considered. Our more nuanced examination of age provides insights into how health services might better target programmes for different ages to potentially reduce unnecessary ED use by providing other health care alternatives.

Assessing quality of older persons' emergency transitions between long-term and acute care settings: a proof-of-concept study.

BACKGROUND: Long-term care (LTC) residents frequently experience transitions in the location of more advanced care delivery, including receiving emergency department (ED) care. In this proof-of-concept study, we aimed to determine if we could identify measures in quality of care across transitions from LTC to the ED, via emergency medical services and back, by applying Institute of Medicine (IOM) Quality of Care Domains to an existing dataset. METHODS: In the Older Persons' Transitions in Care (OPTIC) study, we collected information on residents' transitions in two Western Canadian cities. We applied the IOM's Quality of Care Domains to the OPTIC data to create binary measures of transition quality. We report the median (MED) per cent and IQR of measures met within each domain of quality. RESULTS: We tracked 637 transitions over a 12-month period, with data collected from each setting. We developed 19 safety measures, 20 measures of resident-centred care, 3 measures of timely care and 5 measures of effective care. We were unable to develop measures for equitable care at an individual transfer level. Domain scores varied across individual transitions, with the highest scores in safety (MED 79%, IQR: 63-95), efficiency (66%; IQR: 66-99), and resident-centred (45%; IQR: 25-65), followed by effectiveness (36%; IQR: 16-56), and timeliness (0%; IQR: 0-50). CONCLUSIONS: Our results show variation in scores across the domains of quality suggesting that it is possible to track quality of transitions for individuals across all settings, and not only within settings. We recommend that future work in tracking quality of care be performed at several levels (LTC, region, health authority, province). Such tracking is necessary to evaluate and improve overall quality of care.

Being a member of a novel transitional case management team for patients with unstable housing: an ethnographic study.

BACKGROUND: Homeless and unstably housed individuals face barriers in accessing healthcare despite experiencing greater health needs than the general population. Case management programs are effectively used to provide care for this population. However, little is known about the experiences of providers, their needs, and the ways they can be supported in their roles. Connect 2 Care (C2C) is a mobile outreach team that provides transitional case management for vulnerable individuals in a major Canadian city. Using an ethnographic approach, we aimed to describe the experiences of C2C team members and explore their perceptions and challenges. METHODS: We conducted participant observations and semi-structured interviews with C2C team members. Data analysis consisted of inductive thematic analysis to identify themes that were iteratively discussed. RESULTS: From 36 h of field observations with eight team members and 15 semi-structured interviews with 12 team members, we identified five overarching themes: 1) Hiring the right people & onboarding: becoming part of C2C; 2) Working as a team member: from experience to expertise; 3) Proud but unsupported: adding value but undervalued; 4) Team-initiated coping: satisfaction in the face of emotional strain, and; 5) Likes and dislikes: committed to challenges. CONCLUSIONS: A cohesive team of providers with suitable personal and professional characteristics is essential to care for this complex population. Emotional support and inclusion of frontline workers in operational decisions are important considerations for optimal care and program sustainability.

First Nations status and emergency department triage scores in Alberta: a retrospective cohort study.

BACKGROUND: Previous studies have found that race is associated with emergency department triage scores, raising concerns about potential health care inequity. As part of a project on quality of care for First Nations people in Alberta, we sought to understand the relation between First Nations status and triage scores. METHODS: We conducted a population-based retrospective cohort study of health administrative data from April 2012 to March 2017 to evaluate acuity of triage scores, categorized as a binary outcome of higher or lower acuity score. We developed multivariable multilevel logistic mixed-effects regression models using the levels of emergency department visit, patient (for patients with multiple visits) and facility. We further evaluated the triage of visits related to 5 disease categories and 5 specific diagnoses to better compare triage outcomes of First Nations and non-First Nations patients. RESULTS: First Nations status was associated with lower odds of receiving higher acuity triage scores (odds ratio [OR] 0.93, 95% confidence interval [CI] 0.92-0.94) compared with non-First Nations patients in adjusted models. First Nations patients had lower odds of acute triage for all 5 disease categories and for 3 of 5 diagnoses, including long bone fractures (OR 0.82, 95% CI 0.76-0.88), acute upper respiratory infection (OR 0.90, 95% CI 0.84-0.98) and anxiety disorder (OR 0.67, 95% CI 0.60-0.74). INTERPRETATION: First Nations status was associated with lower odds of higher acuity triage scores across a number of conditions and diagnoses. This may reflect systemic racism, stereotyping and potentially other factors that affected triage assessments.

Characteristics of Pediatric Frequent Users of Emergency Departments in Alberta and Ontario.

OBJECTIVES: Emergency department (ED) volumes have drawn attention to frequent users but less attention has been paid to children. This study examined sociodemographic and ED presentation characteristics of pediatric high-system ED users (HSUs) in 2 provinces in Canada. METHODS: Cohorts of HSUs were created from the National Ambulatory Care Reporting System in 2015/2016 for children with the top 10% of ED presentations. Controls were random samples of non-HSU patients. Factors were explored in multivariable logistic regression models. RESULTS: There were 151,497 HSUs (51.7% girls, average age, 6.4 years) and 591,545 controls (53.1% girls; average age, 7.4 years). High-system ED users were more likely to be younger (adjusted odds ratio [aOR], 0.89 per 5 years; 95% confidence interval [CI], 0.88-0.89), live in less populated areas (aOR, 1.85; 95% CI, 1.82-1.88), and from lowest income neighborhoods (aOR, 1.51; 95% CI, 1.48-1.54) than controls. High-system ED users had higher proportions of presentations for pediatric complex chronic (aOR, 1.25 per 0.25 increase; 95% CI, 1.21-1.29), respiratory (aOR, 1.14 per 0.25; 95% CI, 1.12-1.15), and mental health (aOR, 1.14 per 0.25; 95% CI, 1.13-1.16) conditions than controls. CONCLUSIONS: Complex factors underlie pediatric health care utilization decisions. Findings identified conditions to target in interventions to improve health care access and utilization. Future work should engage children and families to design interventions.

Addressing Communication Breakdowns during Emergency Care Transitions of Older Adults: Evaluation of a Standardized Inter-Facility Health Care Communication Form.

Transitions for older persons from long-term care (LTC) to the emergency department (ED) and back, can result in adverse events. Effective communication among care settings is required to ensure continuity of care. We implemented a standardized form for improving consistency of documentation during LTC to ED transitions of residents 65 years of age or older, via emergency medical services (EMS), and back. Data on form use and form completion were collected through chart review. Practitioners' perspectives were collected using surveys. The form was used in 90/244 (37%) LTC to ED transitions, with large variation in data element completion. EMS and ED reported improved identification of resident information. LTC personnel preferred usual practice to the new form and twice reported prioritizing form completion before calling 911. To minimize risk of harmful unintended consequences, communication forms should be implemented as part of broader quality improvement programs, rather than as stand-alone interventions.

Connect 2 Care, a Novel Community Outreach Program for Vulnerably Housed Patients With High Acute Care Use: A Mixed-Methods Study Protocol.

Introduction: Vulnerably housed individuals, especially those experiencing homelessness, have higher acute care use compared with the general population. Despite available primary care and social services, many face significant challenges accessing needed services. Connect 2 Care (C2C) is a novel transitional case management program that includes registered nurses and health navigators with complementary expertise in chronic disease management, mental health and addictions, social programs, community health, and housing, financial, transportation and legal resources. C2C bridges acute care and community services to improve care coordination. Methods and Analysis: We will perform a mixed-methods evaluation of the C2C program according to the Donabedian framework of structure, process and outcome, to understand how program structure and process, coupled with contextual factors, influence outcomes in a novel intervention. Eligible patients are homeless or unstably housed adults with complex health conditions and high acute care use. Change in emergency department visit rate 12-months after program enrolment is the primary outcome. Secondary outcomes include 12-month post-enrolment hospital admissions, cumulative hospital days, health-related quality of life, housing status, primary care attachment and substance use. Qualitative methods will explore experiences with the C2C program from multiple perspectives and an economic evaluation will assess cost-effectiveness. Discussion: Academic researchers partnered with community service providers to evaluate a novel transitional case management intervention for vulnerably housed patients with high acute-care use. The study uses mixed-methods to evaluate the Connect 2 Care program according to the Donabedian framework of structure, process and outcome, including an assessment of contextual factors that influence program success. Insights gained through this comprehensive evaluation will help refine the C2C program and inform decisions about sustainability and transferability to other settings in Canada.

Opioid use disorder treatment disruptions during the early COVID-19 pandemic and other emergent disasters: a scoping review addressing dual public health emergencies.

BACKGROUND: During public health emergencies, people with opioid use disorder (PWOUD) may be particularly impacted. Emergent disasters such as the COVID-19 pandemic disrupt already-strained harm reduction efforts and treatment availability. This study aims to answer three research questions. How do public health emergencies impact PWOUD? How can health systems respond to novel public health emergencies to serve PWOUD? How can the results of this scoping review be contextualized to the province of Alberta to inform local stakeholder responses to the pandemic? METHODS: We conducted a scoping review using the 6-stage Arksey and O'Malley framework to analyse early-pandemic and pre-pandemic disaster literature. The results of the scoping review were contextualized to the local pandemic response, through a Nominal Group Technique (NGT) process with frontline providers and stakeholders in Alberta, Canada. RESULTS: Sixty one scientific journal articles and 72 grey literature resources were included after full-text screening. Forty sources pertained to early COVID-19 responses, and 21 focused on OUD treatment during other disasters. PWOUD may be more impacted than the general population by common COVID-19 stressors including loss of income, isolation, lack of rewarding activities, housing instability, as well as fear and anxiety. They may also face unique challenges including threats to drug supplies, stigma, difficulty accessing clean substance use supplies, and closure of substance use treatment centres. All of these impacts put PWOUD at risk of negative outcomes including fatal overdose. Two NGT groups were held. One group (n = 7) represented voices from urban services, and the other (n = 4) Indigenous contexts. Stakeholders suggested that simultaneous attention to multiple crises, with adequate resources to allow attention to both social and health systems issues, can prepare a system to serve PWOUD during disasters. CONCLUSION: This scoping review and NGT study uncovers how disasters impact PWOUD and offers suggestions for better serving PWOUD.

First Nations emergency care in Alberta: descriptive results of a retrospective cohort study.

BACKGROUND: Worse health outcomes are consistently reported for First Nations people in Canada. Social, political and economic inequities as well as inequities in health care are major contributing factors to these health disparities. Emergency care is an important health services resource for First Nations people. First Nations partners, academic researchers, and health authority staff are collaborating to examine emergency care visit characteristics for First Nations and non-First Nations people in the province of Alberta. METHODS: We conducted a population-based retrospective cohort study examining all Alberta emergency care visits from April 1, 2012 to March 31, 2017 by linking administrative data. Patient demographics and emergency care visit characteristics for status First Nations persons in Alberta, and non-First Nations persons, are reported. Frequencies and percentages (%) describe patients and visits by categorical variables (e.g., Canadian Triage and Acuity Scale). Means, medians, standard deviations and interquartile ranges describe continuous variables (e.g., age). RESULTS: The dataset contains 11,686,288 emergency care visits by 3,024,491 unique persons. First Nations people make up 4% of the provincial population and 9.4% of provincial emergency visits. The population rate of emergency visits is nearly 3 times higher for First Nations persons than non-First Nations persons. First Nations women utilize emergency care more than non-First Nations women (54.2% of First Nations visits are by women compared to 50.9% of non-First Nations visits). More First Nations visits end in leaving without completing treatment (6.7% v. 3.6%). CONCLUSIONS: Further research is needed on the impact of First Nations identity on emergency care drivers and outcomes, and on emergency care for First Nations women.

Characteristics of frequent users of emergency departments in Alberta and Ontario, Canada: an administrative data study.

OBJECTIVE: Frequent users to emergency departments (EDs) are a diverse group of patients accounting for a disproportionate number of ED presentations. This study examined sociodemographic and ED visit characteristics of adult high-system users in two Canadian provinces. METHODS: Cohorts of high-system users were created for Alberta and Ontario including patients with the top 10% of presentations in the National Ambulatory Care Reporting System (April 2015-March 2016). Controls were random samples of non-high-system user patients. Sociodemographic and ED visits data were used to predict high-system user group membership in a multivariable logistic regression model. RESULTS: There were 579,674 high-system users and 2,115,960 controls. High-system users were more likely to be female [odds ratio (OR) = 1.1, 95% confidence interval (CI) 1.1,1.1], older (OR 1.02 per 5 years, 95% CI 1.02,1.02), from the lowest-income quintile (OR 1.8, 95% CI 1.7,1.8), and more rural (OR 1.6, 95% CI 1.6,1.6) than controls. High-system users had a higher proportion of presentations by ambulance (OR 1.1 per 0.25 increase, 95% CI 1.1,1.1) and disposition was admission/transfer (OR 1.1 per 0.25 increase, 95% CI 1.1,1.1), left without being seen (OR 1.1, 95% CI 1.1,1.1), or left against medical advice (OR 1.1, 95% CI 1.1,1.1) more often than controls. CONCLUSION: High-system users were more likely to be female, older, live in rural areas and within the lowest-income quintile compared to controls. Their heterogeneity in acuity, comorbid chronic diseases, and limited access to primary care suggests that interventions referring high-system users to primary care may be fruitful in reducing ED utilization by high-system users.

RéSUMé: OBJECTIF: Les utilisateurs fréquents des services d'urgence sont un groupe diversifié de patients qui représentent un nombre disproportionné de présentations aux services d'urgence. Cette étude a examiné les caractéristiques sociodémographiques et les visites aux urgences de grands utilisateurs adultes du système de santé dans deux provinces canadiennes. MéTHODE: Des cohortes de grands utilisateurs du système de santé ont été créées pour l'Alberta et l'Ontario, y compris les patients ayant fait l'objet des 10 % de présentations les plus importantes dans le système national d'information sur les soins ambulatoires (avril 2015-mars 2016). Les contrôles étaient des échantillons aléatoires des patients ne faisant pas partie des grands utilisateurs. Les données sociodémographiques et les données sur les visites aux urgences ont été utilisées pour prédire l'appartenance à un groupe de grands utilisateurs du système dans un modèle de régression logistique multivariable. RéSULTATS: Il y avait 579 674 de grands utilisateurs et 2 115 960 témoins. Les grands utilisateurs de système étaient plus susceptibles d'être des femmes (rapport des cotes [RC] = 1,1, intervalle de confiance à 95 % (IC) 1,1, 1,1), plus âgés (RC = 1,02 tous les 5 ans, IC à 95 % 1,02, 1,02), d'après quintile de revenu le plus bas (RC = 1,8, IC à 95 % 1,7,1,8), et plus rural (RC = 1,6, IC à 95 % 1,6,1,6) que les témoins. Les grands utilisateurs du système avaient une proportion plus élevée de présentations par ambulance (RC = 1,1 pour une augmentation de 0,25, IC à 95 % 1,1, 1,1) et la disposition était l'admission / transfert (RC = 1,1 pour une augmentation de 0,25, IC à 95 % 1,1, 1,1), parti sans être vu (OR = 1,1, IC à 95% 1,1, 1,1), ou parti contre l'avis médical (OR = 1,1, IC à 95 % 1,1, 1,1) plus souvent que les témoins. CONCLUSIONS: Les grands utilisateurs du système étaient plus susceptibles d'être des femmes, des personnes âgées, vivant dans des zones rurales et se situant dans le quintile de revenu le plus bas, par rapport aux témoins. Leur hétérogénéité en termes d'acuité, de comorbidité des maladies chroniques et d'accès limité aux soins primaires suggère que les interventions qui orientent les grands utilisateurs du haut système vers les soins primaires peuvent être fructueuses pour réduire l'utilisation des urgences par les grands utilisateurs du système.
