Frequent emergency attenders: is there a better way?

Prevalence and characteristics of frequent presenters to Auburn Hospital emergency department

OBJECTIVES

Frequent presenters (FPs) to the ED are common and contribute to ED overcrowding. Our aim was to identify the proportion of FPs over a 12-month period and to investigate the sociodemographic, clinical and attendance characteristics of FPs.

METHODS

A retrospective cohort study of adult patients (≥18 years) presenting to Auburn Hospital ED between 1 January 2018 to 31 December 2018. Patients with ≥4 presentations in 12 months were classified as FP. Multivariable logistic regression was used to assess associations between sociodemographic characteristics and FP.

RESULTS

During the study period, there were 22 679 presentations to the ED from 16 624 adult patients. FPs represented 5.1% (95% confidence interval [CI] 4.8-5.5) of the total population, but 15.8% of the total ED visits. Median age of FPs was 46 years (interquartile range 29-72), 51.9% were males. Age over 65 was the strongest determinant of FP (odds ratio [OR] 2.33; 95% CI 2.01-2.72 adjusted for sex). FP was more likely for Arabic speakers compared to English speakers (OR 1.54; 95% CI 1.28-1.86 adjusted for age and sex) and least likely for Mandarin speakers (adjusted OR 0.40; 95% CI 0.27-0.59).

CONCLUSIONS

FPs represent a significant proportion of ED visits, yet a small proportion of ED patients. Our findings suggest that identifying ways to provide targeted services to older FPs may reduce the overall rates. The differences between language groups and FP highlights the importance of social context and culture when developing targeted interventions.

What is the prevalence of frequent attendance to emergency departments and what is the impact on emergency department utilisation? A systematic review and meta-analysis

Patients who frequently attend to emergency departments are a varying group and have complex health care needs. This systematic review and meta-analysis aimed to determine the prevalence of patients who have frequent attendance to emergency departments. A systematic review was performed in line with PRISMA guidelines. A database search was conducted, and studies were included in the final review if they analysed a population of frequent attendance. Meta-analysis was performed only on population-based studies to estimate prevalence. The search yielded 2922 nonduplicate publications, of which 27 were included in the meta-analysis. The most common definition used for frequent attendance was greater than three presentations a year. The proportion of people who frequently attended as a percentage of the total study population ranged from 0.01 to 20.9%, with emergency department presentations from frequent attenders ranging from 0.2 to 34%. When limiting the definition of frequent attendance to greater than three visits in a 12-month period, people who frequently attended contributed between 3 and 10% [pooled estimate 6%; CI 4-7%] of emergency department presentations and between 12 and 34% [pooled estimate 21%; CI 15-27%] of total emergency department presentations. Meta-analysis found substantial heterogeneity between estimates [I² > 50%]. The prevalence of frequent attendance compared to the total population of patients seeking emergency care was small, but the impact on emergency department utilisation is significant. Early identification of people attending for frequent care at an emergency department provides the opportunity to implement alternative models of care.

Characteristics of frequent adult emergency department users: A Korean tertiary hospital observational study

Emergency department (ED) crowding is a public health burden that impedes the provision of high-quality emergency care and is related to poor outcomes. Frequent ED visits are known to contribute to ED crowding. This study aimed to identify frequent ED users' characteristics and risk factors related to frequent ED visits.A retrospective observational study was conducted using ED-based data derived from adult patients at a university hospital. The main exposure variable was frequent ED visits, which were defined as ≥4 visits within 12 months (January 1-December 31, 2018). Characteristics and risk factors for frequent ED users were evaluated using stepwise regression analysis.Within the study period, there were 36,932 ED visits involving 29,759 patients. Of these, 3031 (8.2%) visits were from 556 (1.9%) patients classified as frequent ED users. The independent risk factors for frequent ED visits were older patients (≥65 years); the winter season; daytime discharge from ED; patients with medical aid insurance; and patients designated as high acuity at their first visit. Patients with a malignant neoplasm, mental health disorder, alcohol-related liver disease, chronic kidney disease, or chronic obstructive pulmonary disease were associated with more frequent ED visits.Frequent ED users comprised a significant proportion of total ED visits. Frequent ED users were more likely than occasional ED users to be in poorer health, older, or have a chronic disease or a mental health disorder.

Working Together to Connect Care: a metropolitan tertiary emergency department and community care program

Objective Frequent attendance by people to an emergency department (ED) is a global concern. A collaborative partnership between an ED and the primary and community healthcare sectors has the potential to improve care for the person who frequently attends the ED. The aims of the Working Together to Connect Care program are to decrease the number of presentations by providing focused community support and to integrate all healthcare services with the goal of achieving positive, patient-centred and directed outcomes. Methods A retrospective analysis of ED data for 2014 and 2015 was used to ascertain the characteristics of the potential program cohort. The definition used to identify a 'frequent attendee' was more than four presentations to an ED in 1 month. This analysis was used to develop the processes now known as the Working Together to Connect Care program. This program includes participant identification by applying the definition, flagging of potential participants in the ED IT system, case review and referral to community services by ED staff, case conferencing facilitated within the ED and individualised, patient centred case management provided by government and non-government community services. Results Two months after the date of commencement of the Working Together to Connect Care program there are 31 active participants in the program: 10 are on the Mental Health pathway, and one is on the No Consent pathway. On average there are three people recruited to the program every week. The establishment of a new program for supporting frequent attendees of an ED has had its challenges. Identifying systems that support people in their community has been an early positive outcome of this project. Conclusion It is expected that data regarding the number of ED presentations, potential fiscal savings and client outcomes will be available in 2017. What is known about the topic? Frequent attendance at EDs is a global issue and although the number of 'super users' is small compared with non-frequent users, the presentations are high. People in the frequent attendee group will often seek care from multiple EDs for, in the main, mental health issues and substance abuse. Furthermore, frequent ED users are vulnerable and experience higher mortality, hospital admissions and out-patient visits than non-frequent users. Aggressive and assertive outreach, intense coordination of services by integrated care teams, and the need for non-medical resources, such as supportive housing, have positive outcomes for this group of people. What does this paper add? This study uses international research findings in an Australian setting to provide a testing of the generalisability of an assertive and collaborative ED and community case management approach for supporting people who frequent a metropolitan ED. What are the implications for practitioners? The chronicling of a process undertaken to affect change in a health care setting supports practitioners when developing processes for this cohort across different ED contexts.

Statistical tools used for analyses of frequent users of emergency department: a scoping review

OBJECTIVE

Frequent users represent a small proportion of emergency department users, but they account for a disproportionately large number of visits. Their use of emergency departments is often considered suboptimal. It would be more efficient to identify and treat those patients earlier in their health problem trajectory. It is therefore essential to describe their characteristics and to predict their emergency department use. In order to do so, adequate statistical tools are needed. The objective of this study was to determine the statistical tools used in identifying variables associated with frequent use or predicting the risk of becoming a frequent user.

METHODS

We performed a scoping review following an established 5-stage methodological framework. We searched PubMed, Scopus and CINAHL databases in February 2019 using search strategies defined with the help of an information specialist. Out of 4534 potential abstracts, we selected 114 articles based on defined criteria and presented in a content analysis.

RESULTS

We identified four classes of statistical tools. Regression models were found to be the most common practice, followed by hypothesis testing. The logistic regression was found to be the most used statistical tool, followed by χ2 test and t-test of associations between variables. Other tools were marginally used.

CONCLUSIONS

This scoping review lists common statistical tools used for analysing frequent users in emergency departments. It highlights the fact that some are well established while others are much less so. More research is needed to apply appropriate techniques to health data or to diversify statistical point of views.

Frequent use of emergency departments by older people: a comparative cohort study of characteristics and outcomes

Objective

To characterise older people who frequently use emergency departments (EDs) and compare patient outcomes with older non-frequent ED attenders.

Design

Retrospective comparative cohort study. Logistic regression modelling of patient characteristics and health service usage, comparing older frequent ED attenders (≥4 ED attendances in 12 months) to non-frequent ED attenders.

Setting

Three Australian public hospital EDs, with a total of 143 327 emergency attendances in the 12 months.

Participants

People aged ≥65 years attending the ED in financial year 2013/2014.

Main Outcome Measures

The primary outcome was frequent ED use; secondary outcomes were ED length of stay, discharge destination from ED, hospital length of stay, re-presentation within 48 h, hospital readmission within 30 days and in-hospital mortality.

Results

Five percent of older people were frequent attenders (n = 1046/21 073), accounting for 16.9% (n = 5469/32 282) of all attendances by older people. Frequent ED attenders were more likely to be male, aged 75-84 years, arrive by ambulance and have a diagnosis relating to chronic illness. Frequent attenders stayed 0.4 h longer in ED (P < 0.001), were more likely to be admitted to hospital (69.2% vs 67.2%; P = 0.004), and had a 1 day longer hospital stay (P < 0.001). In-hospital mortality for older frequent ED attenders was double that of non-frequent attenders (7.0% vs 3.2%, P < 0.001) over 12 months.

Conclusions

Older frequent ED attenders had more chronic disease and care needs requiring hospital admission than non-frequent attenders. A new approach to care planning and coordination is recommended, to optimise the patient journey and improve outcomes.

Emergency department utilisation by older people in metropolitan Melbourne, 2008–12: findings from the Reducing Older Patient’s Avoidable Presentations for Emergency Care Treatment (REDIRECT) study

Objective Older patients are over-represented in emergency departments (ED), with many presenting for conditions that could potentially be managed in general practice. The aims of the present study were to examine the characteristics of ED presentations by older patients and to identify patient factors contributing to potentially avoidable general practitioner (PAGP)-type presentations. Methods A retrospective analysis was performed of routinely collected data comprising ED presentations by patients aged ≥70 years at public hospitals across metropolitan Melbourne from January 2008 to December 2012. Presentations were classified according to the National Healthcare Agreement definition for PAGP-type presentations. Presentations were characterised according to patient demographic and clinical factors and were compared across PAGP-type and non-PAGP-type groups. Results There were 744 519 presentations to the ED by older people, of which 103 471 (13.9%) were classified as PAGP-type presentations. The volume of such presentations declined over the study period from 20 893 (14.9%) in 2008 to 20 346 (12.8%) in 2012. External injuries were the most common diagnoses (13 761; 13.3%) associated with PAGP-type presentations. Sixty-one per cent of PAGP-type presentations did not involve either an investigation or a procedure. Patients were referred back to a medical officer (including a general practitioner (GP)) in 58.7% of cases. Conclusion Older people made a significant number of PAGP-type presentations to the ED during the period 2008–12. A low rate of referral back to the primary care setting implies a potential lost opportunity to redirect older patients from ED services back to their GPs for ongoing care. What is known about the topic? Older patients are increasingly attending EDs, with a proportion attending for problems that could potentially be managed in the general practice setting (termed PAGP-type presentations). What does this paper add? This study found that PAGP-type presentations, although declining, remain an important component of ED demand. Patients presented for a wide array of conditions and during periods that may indicate difficulty accessing a GP. What are the implications for practitioners? Strategies to redirect PAGP-type presentations to the GP setting are required at both the primary and acute care levels. These include increasing out-of-hours GP services, better triaging and appointment management in GP clinics and improved communication between ED clinicians and patients’ GPs. Although some strategies have been implemented, further examination is required to assess their ongoing effectiveness.

Living with chronic obstructive pulmonary disease: The stories of frequent attenders to the Emergency Department

AIMS AND OBJECTIVES

To explore the experiences of chronic obstructive pulmonary disease (COPD) amongst individuals who have a high frequency of presentations to the Emergency Department and their carers.

BACKGROUND

Patients with COPD are amongst the most frequent attenders in the Emergency Department despite the chronic nature of their condition. Good self-management has previously been identified as a key to maintaining health and reducing COPD exacerbations. There has been limited investigation of those with COPD who frequently attend the Emergency Department.

DESIGN

Descriptive qualitative phase of a mixed methods study.

METHODS

Individuals who had attended an Emergency Department within a single health district at least three times in the previous year for COPD were invited to participate in semistructured face-to-face interviews. A total of 19 individuals consented to participate, of whom 12 were male. Half of the interviews included both those with COPD and carers. Data were audio-recorded and transcribed, before being analysed using thematic analysis.

RESULTS

Five main themes emerged from the data, namely (i) a sense of grief, loss and guilt, yet hope for the future; (ii) the impact on carers; (iii) the end point of self-management; (iv) the healthcare experience; and (v) the primary care experience.

CONCLUSION

The experience of individuals with COPD who frequently present to the Emergency Department and their carers highlights the complexity of living with this disease. Providing effective intervention to manage exacerbation requires an understanding of the issues that are faced by patients and their carers. Clear systems and skills for sharing information are essential to decrease avoidable use of the Emergency Department.

Better safe than sorry? Frequent attendance in a hospital emergency department: an exploratory study

Introduction

Pain accounts for the majority of attendances to the Emergency Department (ED), with insufficient alleviation of symptoms resulting in repeated attendance. People who frequently attend the ED are typically considered to be psychologically and socially vulnerable in addition to experiencing health difficulties. This service development study was commissioned to identify the defining characteristics and unmet needs of frequent attenders (FAs) in a UK acute district general hospital ED, with a view to developing strategies to meet the needs of this group.

Methods

A mixed-methods multi-pronged exploratory approach was used, involving staff interviews, focus groups, business data and case note analysis.

Results

Findings reflect an absence of a coherent approach to meeting the needs of FAs in the ED, especially those experiencing pain. FAs to this ED tend to be vulnerable, complex and report significant worry and anxiety. Elevated anxiety on the part of the patient may be contributing to a 'better safe than sorry' culture within the ED and is reported to bear some influence on the clinical decision-making process.

Discussion

It is recommended that a systemic approach is taken to improve the quality and accessibility of individualised care plans, provision of patient education, psychological care and implementation of policies and procedures. Change on an organisational level is likely to improve working culture, staff satisfaction and staff relationships with this vulnerable group of patients. A structured care pathway and supportive changes are likely to lead to economic benefits. Further research should build on findings to implement and test the efficacy of these interventions.

Contributing factors of frequent use of the emergency department: A synthesis

INTRODUCTION

Overcrowding in emergency departments is an issue that has a negative impact worldwide. As attendance in emergency departments has increased, the ability to provide critical services to patients suffering from actual medical emergencies in a timely manner has decreased as these departments are many times at or over capacity. One patient population whose negative influence has been researched with regard to their impact on the overcrowding issue is that of the frequent user.

METHODS

A search of two electronic databases was conducted to identify factors that frequent users state as their reasoning for using an emergency department. Peer reviewed articles in English were searched for in CINAHL Plus and PubMed, as well as a review of reference lists.

RESULTS

A review of the literature identified two predominant factors related to frequent users in the emergency department: a lack of awareness of medical necessity and issues of access.

DISCUSSION

To address the frequent users in emergency departments, implications for practice need to be explored and implemented. Implications for practice include education of medical necessity for the frequent users, expansion of the pre-hospital role in primary care and inappropriate use prevention, and improvement of access to alternative healthcare services.

Factors contributing to frequent attendance to the emergency department of a remote Northern Territory hospital

OBJECTIVES

To determine the clinical and environmental variables associated with frequent presentations by adult patients to a remote Australian hospital emergency department (ED) for reasons other than chronic health conditions.

DESIGN

Unmatched case-control study of all adult patients attending Katherine Hospital ED between 1 January and 31 December 2012.

PARTICIPANTS

Cases were defined as frequent attenders (FAs) without a chronic health condition who presented to the ED six or more times during the 12-month period. A single presentation was randomly selected for data collection. Controls were patients who presented on only one occasion.

OUTCOME MEASURES

Basic demographic data were collected, including clinical outcomes, Indigenous status, living arrangements, and whether alcohol and violence contributed to the presentation. Environmental variables were extracted from the Bureau of Meteorology database and mapped to each presentation.

RESULTS

FAs were much more likely to be homeless (odds ratio [OR], 16.4; P < 0.001) and to be Aboriginal (OR, 2.16; P < 0.001); alcohol as a contributing factor was also more likely (OR, 2.77; P = 0.001). FAs were more likely to present in hotter, wetter weather, although the association was statistically weak. Clinical presentations by cases and controls were similar; the annual death rates for both groups were high (3.6% and 1.5%, respectively).

CONCLUSIONS

There was a strong association between FA and Aboriginal status, homelessness and the involvement of alcohol, but alcohol was more likely to contribute to presentation by non-Aboriginal FAs who had stable living conditions. FAs and non-FAs had similar needs for emergency medical care, with strikingly higher death rates than the national average in both groups. As a result of this study, Katherine Hospital has initiated a Frequent Attender Pathway that automatically triggers a dedicated ED service for those at greatest clinical risk. Homelessness is a serious problem in the Northern Territory, and is associated with poor health outcomes.

Frequent users of the emergency department services in the largest academic hospital in the Netherlands: a 5-year report

OBJECTIVE

To investigate the demographic and service characteristics, motive for consultation, and disposition of adult frequent users (FUs) of the largest academic hospital in the Netherlands over a 5-year period.

PATIENTS AND METHODS

This retrospective study included all patients aged 18 years and older visiting the emergency department (ED) during a 5-year period (2009-2013). Frequent ED use was defined as having four or more visits to the ED during a year. Patient and service characteristics, motive for consultation, and disposition were explored.

RESULTS

Frequent ED users represented 2% of all patients who visited the ED during 2009-2013 (8% of all ED consultations). On average, each FU visited the ED five times per year. Compared with nonfrequent users (NFUs), FUs were significantly less often self-referred, less frequently transported to the hospital by ambulance, received a lower urgency code upon arrival to the ED, and more often admitted to hospital than NFUs. Complaints related to the digestive system (19%), general complaints such as fever (18%), respiratory (10%), or cardiovascular problems (10%) were the main motive for consultations of the frequent ED users. Two percent of the FUs were serial FUs (FUs during 3 or more consecutive years).

CONCLUSION

Frequent use of the ED has been depicted as inappropriate use of these services. However, our study shows that FUs consist of a relatively small number of patients and that FUs suffer from chronic, and often, severe somatic illnesses that require specialized medical care.

Hospital social work in Australia: emerging trends or more of the same?

Social work in health care has been established for more than 100 years and is one of the largest areas of practice for social workers. Over time, demographic changes and growth in the aging population, increased longevity rates, an explosion in rates of chronic illness together with rapidly increasing cost of health care have created serious challenges for acute hospitals and health social workers. This article reviews the Australian health care system and policies with particular emphasis on the public hospital system. It then examines current hospital social work roles, including the continued role in discharge planning and expanding responsibility for emerging client problems, such as patient complexity, legal, and carer issues. The article concludes with a discussion of evolving issues and challenges facing health social work to ensure that social work remain relevant within this practice context.

Determinants of nonurgent use of the emergency department for pediatric patients in 12 hospitals in Belgium

INTRODUCTION

The nonurgent use of the emergency department (ED) for pediatric patients is an increasing problem facing healthcare systems worldwide. To evaluate the magnitude of the phenomenon and to identify associated factors, an observational prospective survey was performed including all patients (<15 years) attending the ED in 12 Belgian hospitals during 2 weeks in autumn 2010. Use of ED was considered appropriate if at least one of the following criteria was met: child referred by doctor or police, brought by ambulance, in need for short stay, technical examination or orthopedic treatment, in-patient admission, or death. Among the 3,117 children, attending ED, 39.9 % (1,244) of visits were considered inappropriate. Five factors were significantly associated with inappropriate use: age of child, distance to ED, having a registered family doctor, out-of-hours visit, and geographic region. The adjusted odds ratio and 95 % confidence intervals are respectively-1.7 (1.3-2.0), 1.7 (1.3-2.2), 1.5 (1.1-2.2), 1.5 (1.2-1.9), and 0.6 (0.5-0.8).

CONCLUSIONS

Almost 40 % of all paediatric ED attendances did not require hospital expertise. The risk of an inappropriate use of ED by pediatrician patients is predominantly associated with organizational and cultural factors. Access, equity, quality of care, and medical human resources availability have to be taken into account to design financially sustainable model of care for those patients. Furthermore, future research is needed to explain reasons why parents visit ED rather than using of primary-care services.
