Characteristics of attenders and their attendances at an urban accident and emergency department over a one year period

Frequent visitors to the ophthalmology emergency department: Clinical characteristics and management

PURPOSE

To describe the profiles and management patterns of frequent visitors to the ophthalmology emergency department in comparison to patients who visit only occasionally.

METHODS

This study conducted a retrospective analysis spanning a 2.5-year period encompassing all visits to the ophthalmology emergency department. Patients who visited four or more times during this period were identified as frequent users and compared with a control group randomly selected from patients who visited only once. Severity scores associated with diagnoses, ranging from 1 to 5 (Base Score), along with clinical characteristics and patient management strategies, were analyzed using both univariate and multivariate analyses.

RESULTS

Of 18,802 visits, 331 patients (constituting 2.23% of the total) were identified as frequent users during the 2.5-year period, with numbers of visits ranging from 4 to 23. In comparison to the control group, frequent users tended to be approximately 10 years older and presented with more severe diagnoses (Base Score 2.43±1.15 versus 1.89±0.94, P=6.35×10-11). Their visits were predominantly associated with non-traumatic anterior segment pathologies (56% versus 27%) rather than traumatic pathologies (8.7% versus 27%). They were more likely to be referred to senior practitioners within the department (43% versus 33%), necessitated more frequent hospitalizations (33 cases versus 1), and required post-emergency follow-ups or referrals to hyper-specialized consultants.

CONCLUSION

Despite comprising a relatively small percentage of the total patient population, frequent users of ophthalmological emergency departments tend to present with more severe diagnoses. This underscores the importance of optimizing resources to alleviate some of the burden on specialized emergency services.

Measuring the impact of an acute visiting scheme on emergency department attendances - a pre-post cohort design

BACKGROUND

Emergency department (ED) attendances are contributing to rising costs of the National Health Service (NHS) in England. Critically assessing the impact of new services to reduce emergency department use can be difficult as new services may create additional access points, unlocking latent demand. The study evaluated an Acute Visiting Scheme (AVS) in a primary care context. We asked if AVS reduces overall ED demand and whether or not it changed utilisation patterns for frequent attenders.

METHOD

The study used a pre post single cohort design. The impact of AVS on all-cause ED attendances was hypothesised as a substitution effect, where AVS duty doctor visits would replace emergency department visits. Primary outcome was frequency of ED attendances. End points were reduction of frequency of service use and increase of intervals between attendances by frequent attenders.

RESULTS

ED attendances for AVS users rose by 47.6%. If AVS use was included, there was a more than fourfold increase of total service utilisation, amounting to 438.3%. It shows that AVS unlocked significant latent demand. However, there was some reduction in the frequency of ED attendances for some patients and an increase in time intervals between ED attendances for others.

CONCLUSION

The study demonstrates that careful analysis of patient utilisation can detect a differential impact of AVS on the use of ED. As the new service created additional access points for patients and hence introduces an element of choice, the new service is likely to unlock latent demand. This study illustrates that AVS may be most useful if targeted at specific patient groups who are most likely to benefit from the new service.

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.

Recurrent Emergency Department Users: Two Categories with Different Risk Profiles

Recurrent emergency department (ED) visits are responsible for an increasing proportion of overcrowding. Therefore, our aim was to investigate the characteristics and prevalence of recurrent ED visitors as well as to determine risk factors associated with multiple ED visits. ED patients visiting the ED of a tertiary care hospital at least four times consecutively in 2015 were enrolled. Of 33,335 primary ED visits, 1921 ED visits (5.8%) were performed by 372 ED patients who presented in the ED at least four times within the one-year period. Two different categories of recurrent ED patients were identified: repeated ED users presenting always with the same symptoms and frequent ED visitors who were suffering from different symptoms on each ED visit. Repeated ED users had more ED visits (p < 0.001) and needed more hospital admissions (p < 0.010) compared to frequent ED users. Repeated ED users visited the ED more likely due to symptoms from chronic obstructive pulmonary diseases (p < 0.001) and mental disorders (p < 0.001). In contrast, frequent ED patients showed to be at risk for multiple ED visits when being disabled (p = 0.001), had an increased Charlson co-morbidity index (p = 0.004) or suffering from rheumatic diseases (p < 0.001). A small number of recurrent ED visitors determines a relevant number of ED visits with a relevance for and impact on patient centred care and emergency services. There are two categories of recurrent ED users with different risk factors for multiple ED visits: repeated and frequent. Therefore, multi-professional follow-up care models for recurrent ED patients are needed to improve patients' needs, quality of life as well as emergency services.

Profiling frequent attenders at an inner city emergency department

BACKGROUND

Emergency department (ED) frequent attenders (FAs) have a higher rate of adverse outcomes compared to infrequent attenders.

AIMS

The primary aim was to describe the prevalence of FAs at an inner city ED. A subgroup analysis was undertaken for high and very high FAs to establish demographics and other factors which might cause them to attend frequently.

METHODS

A retrospective review of all patients who attended the ED at Mercy University Hospital (MUH), Cork, during 2016 was undertaken. Patients were classified as either infrequent attenders (1-2 attendances/year), frequent attenders (3-12 attendances/year), high frequent attenders (HFA, 13-29 attendances/year), or very high frequent attenders (VHFA, > 30 attendances/year).

RESULTS

During 2016, a total of 21,920 patients presented 33,152 times. Overall, 90.2% (n = 19,761) were infrequent attenders, whilst 9.6% (n = 2115) were FAs. A further 36 patients (0.16%) were HFAs and eight patients (0.04%) were classified as VHFAs. Almost 10% of patients attended the ED three or more times, accounting for 29% of overall ED attendances. The HFA and VHFA cohorts were predominantly male (79.5%, n = 35) with an average age of 49.6 years. They were found to have multiple medical comorbidities, complex psychosocial problems, and a mortality rate of 11.3% over a 2-year period.

CONCLUSIONS

This retrospective review is the most detailed assessment of Irish FAs undertaken to date. Further studies are required to examine the Irish hospitals most at need of Case Management Strategy Programmes which we postulate could minimise the risk of adverse outcomes for these patients and improve overall ED efficiency.

Frequent users of Mental Health Liaison Services within Emergency Departments

This study aimed to use nuanced statistical methods in a large UK sample to identify and explore the factors associated with different types of frequent user of Emergency Departments (EDs) who are referred to Mental Health Liaison Services (MHLS). A retrospective 5-year longitudinal study was conducted of all attenders (n = 23,718) of four London EDs who were referred to their MHLS. Longitudinal group-based trajectory analysis of monthly MHLS referrals enabled identification of factors which may contribute to membership of the resulting groups. Analysis revealed six clusters representing distinct attendance patterns; three clusters of these were identified as frequent attender groups (occasional, intermediate, heavy) containing 1119 people (4.7%). This 4.7% of the sample accounted for 24.2% of all admissions. Factors significantly related to membership of each of these groups were: having been involuntarily detained under the Mental Health Act, a higher number of care coordinators, and a diagnosis of substance abuse. The study revealed three clusters of frequent ED users with a MHLS referral who were more likely to have certain clinical and social care needs. A small proportion of clients identified as frequent users (4.7%) were responsible for nearly a quarter of all admissions (24.2%) during this timeframe.

Key factors of case management interventions for frequent users of healthcare services: a thematic analysis review

OBJECTIVE

The aim of this paper was to identify the key factors of case management (CM) interventions among frequent users of healthcare services found in empirical studies of effectiveness.

DESIGN

Thematic analysis review of CM studies.

METHODS

We built on a previously published review that aimed to report the effectiveness of CM interventions for frequent users of healthcare services, using the Medline, Scopus and CINAHL databases covering the January 2004-December 2015 period, then updated to July 2017, with the keywords 'CM' and 'frequent use'. We extracted factors of successful (n=7) and unsuccessful (n=6) CM interventions and conducted a mixed thematic analysis to synthesise findings. Chaudoir's implementation of health innovations framework was used to organise results into four broad levels of factors: (1) ,environmental/organisational level, (2) practitioner level, (3) patient level and (4) programme level.

RESULTS

Access to, and close partnerships with, healthcare providers and community services resources were key factors of successful CM interventions that should target patients with the greatest needs and promote frequent contacts with the healthcare team. The selection and training of the case manager was also an important factor to foster patient engagement in CM. Coordination of care, self-management support and assistance with care navigation were key CM activities. The main issues reported by unsuccessful CM interventions were problems with case finding or lack of care integration.

CONCLUSIONS

CM interventions for frequent users of healthcare services should ensure adequate case finding processes, rigorous selection and training of the case manager, sufficient intensity of the intervention, as well as good care integration among all partners. Other studies could further evaluate the influence of contextual factors on intervention impacts.

Individual predictors of frequent emergency department use: a scoping review

BACKGROUND

A small proportion of patients use an excessively large amount of emergency care resources which often results in emergency department (ED) overcrowding, decreased quality of care and efficiency. There is a need to better identify these patients in order to target those who will benefit most from interventions adapted to their specific needs. We aimed to identify the predictive factors of short-term frequent use of ED (over a 1-year period) and chronic frequent use of ED (over a multiple-year period) and to highlight recurring characteristics in patients.

METHODS

A scoping review was performed of all relevant articles found in Medline published between 1979 and 2015 (Ovid). This scoping review included a total of 20 studies, of these, 16 articles focussed on frequent ED users and four others on chronic frequent ED users.

RESULTS

A majority of articles confirm that patients who frequently visit the ED are persons of low socioeconomic status. Both frequent and chronic frequent ED users show high levels of health care use (other than the ED) and suffer from multiple physical and mental conditions.

CONCLUSIONS

This research highlights which individual factors predict frequent emergency department use. Further research is needed to better characterize and understand chronic frequent users as well as the health issues and unmet medical needs that lead to chronic frequent ED use.

Frequent Users of Hospital Emergency Departments in Korea Characterized by Claims Data from the National Health Insurance: A Cross Sectional Study

The Korean National Health Insurance, which provides universal coverage for the entire Korean population, is now facing financial instability. Frequent emergency department (ED) users may represent a medically vulnerable population who could benefit from interventions that both improve care and lower costs. To understand the nature of frequent ED users in Korea, we analyzed claims data from a population-based national representative sample. We performed both bivariate and multivariable analyses to investigate the association between patient characteristics and frequent ED use (4+ ED visits in a year) using claims data of a 1% random sample of the Korean population, collected in 2009. Among 156,246 total ED users, 4,835 (3.1%) were frequent ED users. These patients accounted for 14% of 209,326 total ED visits and 17.2% of $76,253,784 total medical expenses generated from all ED visits in the 1% data sample. Frequent ED users tended to be older, male, and of lower socio-economic status compared with occasional ED users (p < 0.001 for each). Moreover, frequent ED users had longer stays in the hospital when admitted, higher probability of undergoing an operative procedure, and increased mortality. Among 8,425 primary diagnoses, alcohol-related complaints and schizophrenia showed the strongest positive correlation with the number of ED visits. Among the frequent ED users, mortality and annual outpatient department visits were significantly lower in the alcohol-related patient subgroup compared with other frequent ED users; furthermore, the rate was even lower than that for non-frequent ED users. Our findings suggest that expanding mental health and alcohol treatment programs may be a reasonable strategy to decrease the dependence of these patients on the ED.

A novel approach for managing the growing demand for ambulance services by low-acuity patients

Objective The aim of the present study was to describe the Ambulance Victoria (AV) secondary telephone triage service, called the Referral Service (RS), for low-priority patients calling triple zero. This service provides alternatives to ambulance dispatch, such as doctor or nurse home visits. Methods A descriptive epidemiological review of all the cases managed between 2009 and 2012 was conducted, using data from AV case records, the Victorian Admitted Episodes Dataset and the Australian Bureau of Statistics. Cases were reviewed for patient demographics, condition, final disposition and RS outcome. Results In all, 107148 cases were included in the study, accounting for 10.3% of the total calls for ambulance attendance. Median patient age was 54 years and 55% were female. Geographically based socioeconomic status was associated with the rate of calls to the RS (r = –0.72; 95% confidence interval CI –0.104, –0.049; P < 0.001). Abdominal pain and back symptoms were the most common patient problems. Although 68% of patients were referred to the emergency department, only 27.6% of the total cases were by emergency ambulance; the remainder were diverted to non-emergency ambulance or the patient’s own private transport. The remaining 32% of cases were referred to alternative service providers or given home care advice. Conclusions This paper describes the use of an ongoing secondary triage service, providing an effective strategy for managing emergency ambulance demand. What is known about the topic? Some calls to emergency services telephone numbers for ambulance assistance consist of cases deemed to be low-acuity that could potentially be better managed in the primary care setting. The demand on ambulance resources is increasing each year. Secondary telephone triage systems have been trialled in ambulance services in the US and UK with minimal success in terms of overall impact on ambulance resourcing. What does this paper add? This study describes a model of secondary telephone triage in the ambulance setting that has provided an effective way to divert patients to more suitable forms of health care to meet their needs. What are the implications for practitioners? The implications for practitioners are vast. Some of the issues that currently face paramedics include: fatigue because of high workloads; skills decay because of a lack of exposure to patients requiring intervention with skills the paramedics have, as well as a lack of time for paramedics to practice these skills during their downtime; and decreasing job satisfaction linked to both these factors. Implications for patients include quicker response times because more ambulances will be available to respond and increased patient safety because of decreased fatigue and higher skill levels in paramedics.

Factors Contributing to Inappropriate Visits of Frequent Attenders and Their Economic Effects at an Emergency Department in Singapore

OBJECTIVES

This study aimed to determine which factors contribute to frequent visits at the emergency department (ED) and what proportion were inappropriate in comparison with nonfrequent visits.

METHODS

This study was a retrospective, case-control study comparing a random sample of frequent attenders and nonfrequent attenders, with details of their ED visits recorded over a 12-month duration. Frequent attenders were defined as patients with four or more visits during the study period.

RESULTS

In comparison with nonfrequent attenders (median age = 45.0 years, interquartile range [IQR] = 28.0 to 61.0 years), frequent attenders were older (median = 57.5 years, IQR = 34.0 to 74.8 years; p = 0.0003). They were also found to have more comorbidities, where 53.3% of frequent attenders had three or more chronic illnesses compared to 14% of nonfrequent attenders (p < 0.0001), and were often triaged to higher priority (more severe) classes (frequent 52.2% vs. nonfrequent 37.6%, p = 0.0004). Social issues such as bad debts (12.7%), heavy drinking (3.3%), and substance abuse (2.7%) were very low in frequent attenders compared to Western studies. Frequent attenders had a similar rate of appropriate visits to the ED as nonfrequent attenders (55.2% vs. 48.1%, p = 0.0892), but were more often triaged to P1 priority triage class (6.7% vs. 3.2%, p = 0.0014) and were more often admitted for further management compared to nonfrequent attenders (47.5% vs. 29.6%, p < 0.001). The majority of frequent attender visits were appropriate (55.2%), and of these, 81.1% resulted in admission. For the same number of patients, total visits made by frequent attenders ($174,247.60) cost four times as much as for nonfrequent attenders ($40,912.40). This represents a significant economic burden on the health care system.

CONCLUSIONS

ED frequent attenders in Singapore were associated with higher age and presence of multiple comorbidities rather than with social causes of ED use. Even in integrated health systems, repeat ED visits are frequent and expensive, despite minimal social causes of acute care. EDs in aging populations must anticipate the influx of vulnerable, elderly patients and have in place interventional programs to care for them.

Social deprivation and adult blunt chest trauma: A retrospective study

INTRODUCTION

The relationship between socioeconomic status and various components of health is well established. Research has also highlighted that social deprivation can affect patterns of injury and outcome after trauma. The interaction between outcomes following blunt chest trauma and socioeconomic status has received limited attention in trauma research. The aim of this study was to investigate the relationship between socioeconomic factors, mechanisms of injury and outcomes following blunt chest trauma using deprivation measures calculated on the basis of domicile postcodes.

METHODS

A retrospective study design was used in order to examine the medical notes of all blunt chest wall trauma patients who presented to the ED of a large regional trauma centre in South West Wales in 2012 and 2013. Baseline characteristics were presented as median and interquartile range or numbers and percentages. Differences between the baseline characteristics were analysed using Mann-Whitney U test and Fisher's exact test. Odds ratios and 95% confidence intervals were presented from the univariable analysis. Multivariable logistic regression analysis was used to identify significant predictors for the development of complications.

RESULTS

Patients in the 'more deprived' group were more likely to be the victims of assault (p < 0.001) and were more likely to have an unplanned re-attendance at the Emergency Department than the patients in the 'less deprived' group (p < 0.001). On multivariable analysis, social deprivation was not a risk factor for the development of complications, but it was a significant risk factor for prolonged length of stay (p < 0.05).

CONCLUSIONS

This is the first study in which social deprivation has been investigated as a risk factor for complications following isolated blunt chest wall trauma. Residing in a 'more deprived' area in South West Wales is not associated with the development of complications following isolated blunt chest wall trauma.

Cost-effective: emergency department care coordination with a regional hospital information system

BACKGROUND

Frequent and unnecessary utilization of the emergency department (ED) is often a sign of serious latent patient issues, and the associated costs are shared by many. Helping these patients get the care they need in the appropriate setting is difficult given their complexity, and their tendency to visit multiple EDs.

STUDY OBJECTIVE

We analyzed the cost-effectiveness of a multidisciplinary ED-care-coordination program with a regional hospital information system capable of sharing patients' individualized care plans with cooperating EDs.

METHODS

ED visits, treatment costs, cost per visit, and net income were assessed pre- and postenrollment in the program using nonparametric bootstrapping techniques. Individuals were categorized as frequent (3-11 ED visits in the 365 days preceding enrollment) or extreme (≥12 ED visits) users. Regression to the mean was tested using an adjusted measure of change.

RESULTS

Both frequent and extreme users experienced significant decreases in ED visits (5 and 15, respectively; 95% confidence intervals [CI] 2-5 and 13-17, respectively) and direct-treatment costs ($1285; 95% CI $492-$2364 and $6091; 95% CI $4298-$8998, respectively), leading to significant hospital cost savings and increased net income ($431; 95% CI $112-$878 and $1925; 95% CI $1093-$3159, respectively). The results further indicate that fewer resources were utilized per visit. Regression to the mean did not seem to be an issue.

CONCLUSIONS

When examined as a whole, research on the program suggests that expanding it would be an efficient allocation of hospital, and possibly societal, resources.

Effectiveness of case management strategies in reducing emergency department visits in frequent user patient populations: a systematic review

BACKGROUND

Case management (CM) is a commonly cited intervention aimed at reducing Emergency Department (ED) utilization by "frequent users," a group of patients that utilize the ED at disproportionately high rates. Studies have investigated the impact of CM on a variety of outcomes in this patient population.

OBJECTIVES

We sought to examine the evidence of the effectiveness of the CM model in the frequent ED user patient population. We reviewed the available literature focusing on the impact of CM interventions on ED utilization, cost, disposition, and psychosocial variables in frequent ED users.

DISCUSSION

Although there was heterogeneity across the 12 studies investigating the impact of CM interventions on frequent users of the ED, the majority of available evidence shows a benefit to CM interventions. Reductions in ED visitation and ED costs are supported with the strongest evidence.

CONCLUSION

CM interventions can improve both clinical and social outcomes among frequent ED users.

Effectiveness of interventions targeting frequent users of emergency departments: a systematic review

STUDY OBJECTIVE

Frequent users of emergency departments (EDs) are a relatively small group of vulnerable patients accounting for a disproportionally high number of ED visits. Our objective is to perform a systematic review of the type and effectiveness of interventions to reduce the number of ED visits by frequent users.

METHODS

We searched MEDLINE, EMBASE, CINAHL, PsychINFO, the Cochrane Library, and ISI Web of Science for randomized controlled trials, nonrandomized controlled trials, interrupted time series, and controlled and noncontrolled before-and-after studies describing interventions targeting adult frequent users of EDs. Primary outcome of interest was the reduction in ED use. We also explored costs analyses and various clinical (alcohol and drug use, psychiatric symptoms, mortality) and social (homelessness, insurance status, social security support) outcomes.

RESULTS

We included 11 studies (3 randomized controlled trials, 2 controlled and 6 noncontrolled before-and-after studies). Heterogeneity in both study designs and definitions of frequent users precluded meta-analyses of the results. The most studied intervention was case management (n=7). Only 1 of 3 randomized controlled trials showed a significant reduction in ED use compared with usual care. Six of the 8 before-and-after studies reported a significant reduction in ED use, and 1 study showed a significant increase. ED cost reductions were demonstrated in 3 studies. Social outcomes such as reduction of homelessness were favorable in 3 of 3 studies, and clinical outcomes trended toward positive results in 2 of 3 studies.

CONCLUSION

Interventions targeting frequent users may reduce ED use. Case management, the most frequently described intervention, reduced ED costs and seemed to improve social and clinical outcomes. It appears to be beneficial to patients and justifiable for hospitals to implement case management for frequent users in the framework of a clear and consensual definition of frequent users and standardized outcome measures.

Review article: People who present on multiple occasions to emergency departments

Research about people who present on multiple occasions to the ED began in the 1980s. Despite this, little is known of their journey as patients. Understanding ED use as a journey can help clinicians improve how they meet the needs of this patient group. Multiple terms were used to identify research on the use of the ED. Papers were included if they had a primary focus on multiple presentations by the general ED population. Integrative review methods were used to extract findings related to the patients' journeys. The findings confirm a sequence of events and processes that provide an outline of the journey through the experience of people who present on multiple occasions. The journey concerns people's decisions to present and re-present to the ED, their assessments on arrival, dilemmas of treatment, outcomes of care and long-term health outcomes. This patient group often have high and complex health needs, engage extensively with other health services and have poor long-term health outcomes. The issue of multiple presentations to the ED is complex and ongoing because of the morbidity of the people concerned, the preference of patients to attend, the purpose of the ED and preparation and role of the personnel and the difficulties with continuity of care. The provision of care for people who present on multiple occasions can be improved within the ED and health services generally through a better understanding of presentations.

The impact of frequent attenders on a UK emergency department

BACKGROUND

Previous studies have identified that there is a cohort of frequent attenders to the emergency department (ED). Recent initiatives aim to provide care closer to home and alternatives to ED attendance. This study aims to identify what impact frequent attenders still have on the ED.

METHODS

A chart review of frequent attenders to the ED was carried out over a 12-month period. Inclusion criterion was 10 or more attendances. Information collected comprised age, sex, postcode, next of kin, number of attendances, day of the week, time, referral source, mode of arrival, triage category, disposal, association with alcohol and drug use, presenting complaint, and diagnosis.

RESULTS

Forty-four frequent users met the study criterion accounting for 1.9% of departmental activity. Sixty-four percent of frequent attenders were male with an average age of 49 years (range 19-83). The majority lived within 5 miles of the ED. Sixty percent of attendances arrived at the ED through ambulance. Documentation of either concurrent alcohol use or history of alcohol dependence and illicit drug use was reported in 54.6 and 15.9% of patients. The admission rate of this group was 38.5% higher than the total ED admission rate of 22%.

CONCLUSION

There remains a cohort of frequent attenders that use the ED for their healthcare needs. A significant proportion of these attendances are associated with alcohol use, chronic disease or mental health problems. Reduction of attendances may be achieved by case management strategies and improving access to primary care and drug and alcohol services.

Frequent use of the emergency department among persons with systemic lupus erythematosus

OBJECTIVE

To describe characteristics of systemic lupus erythematosus (SLE) patients who are frequent users of the emergency department and to identify predictors of frequent emergency department use.

METHODS

Data for this study were derived from the University of California, San Francisco Lupus Outcomes Study, a large cohort of persons with SLE who undergo annual structured interviews. Participants were categorized into 1 of 3 levels of emergency department utilization: nonusers (no visits in the preceding year), occasional users, (1-2 visits), and frequent users (> or =3 visits). We compared characteristics of the 3 groups and determined predictors of frequent emergency department use (> or =3 visits) using multivariate logistic regression, adjusting for a variety of potential confounding covariates.

RESULTS

Of 807 study participants, 499 (62%) had no emergency department visits; 230 (28%) had occasional emergency department visits (1-2 visits); and 78 (10%) had frequent (> or =3 visits) emergency department visits. Frequent users were younger, less likely to be employed, and less likely to have completed college. They also had greater disease activity, worse general health status, and more depressive symptoms. Frequent emergency department users were more likely to have Medicaid as their principal insurance. In multivariate logistic regression, older age predicted a lower likelihood of frequent emergency department visits, whereas greater disease activity and having Medicaid insurance predicted a higher likelihood of frequent emergency department visits.

CONCLUSION

In persons with SLE, greater disease activity and Medicaid insurance are associated with more frequent emergency department use.

Emergency department patients with psychiatric complaints return at higher rates than controls

STUDY OBJECTIVE

At our 35,000 visit/year emergency department (ED), we studied whether patients presenting to the ED with psychiatric complaints were admitted to the hospital at a higher rate than non-psychiatric patients, and whether these patients had a higher rate of reevaluation in the ED within 30 days following the index visit.

METHODS

We reviewed the electronic records of all ED patients receiving a psychiatric evaluation from January to February 2007 and compared these patients to 300 randomly selected patients presenting during the study period for non-psychiatric complaints. Patients were followed for 30 days, and admission rates and return visits were compared.

RESULTS

Two hundred thirty-four patients presented to the ED and were evaluated for psychiatric complaints during the study period. Twenty-four point seven percent of psychiatric patients were admitted upon initial presentation versus 20.7% of non-psychiatric patients (p = 0.258). Twenty-one percent of discharged psychiatric patients returned to the ED within 30 days versus 13.4% of discharged non-psychiatric patients (p=0.041). Patients returning to the ED within 30 days had a 17.1% versus 21.6% admission rate for the psychiatric and non-psychiatric groups, respectively (p=0.485).

CONCLUSION

Patients presenting to this ED with psychiatric complaints were not admitted at a significantly higher rate than non-psychiatric patients. These psychiatric patients did, however, have a significantly higher return rate to the ED when compared to non-psychiatric patients.

Predictors and outcomes of frequent chest pain unit users

AIM

To determine predictors of frequent chest pain unit (CPU) users and to identify characteristics and outcomes of their CPU visits.

PATIENTS AND METHODS

Observational prospective case-control study. Frequent CPU user was defined by 3 or more CPU visits within the study year. A control patient and a control visit were randomly selected for each case patient and case visit. Demographic, clinical, and outcome variables were collected from medical record and phone interview performed in a 30-day interval. A multivariate logistic regression analysis was used to identify frequent CPU users' predictors.

RESULTS

Of 1934 patients presenting during the year, 80 (4.1%) met the definition for case patient. They accounted for 352 (13%) of 2709 CPU visits. Sixty-seven (83.7%) case patients and 71 (88.7%) control patients were contacted. The final predictors were the following: Karnofsky Performance Scale of 70 or lesser (odds ratio [OR], 5.24 [95% confidence interval {CI}, 1.71-16.06]), previous hospitalization (OR, 3.76 [95% CI, 1.49-9.49]), previously known coronary artery disease (OR, 3.72 [95% CI, 1.32-10.52]), and symptoms of depression (OR, 2.98 [95% CI, 1.14-7.78]). Case visits were more likely at night (OR, 2.41 [95% CI, 1.64- 3.52]), generated more diagnostic uncertainty (OR, 2.39 [95% CI, 1.71-3.35]), but did not increase the need of hospital admission.

CONCLUSIONS

Frequent CPU user is associated with previously known coronary artery disease, previous hospitalization, impaired performance status, and presence of symptoms of depression. They are more likely to arrive on CPU at night and generate more diagnostic uncertainty.

Hyper-use of the ED

OBJECTIVES

This study aims to describe the population that averages one or more emergency department (ED) visits per month and compare them to the general ED population to determine if there are associated characteristics.

METHODS

A retrospective cohort study conducted in a teaching hospital between January 1, 2001, and December 31, 2004, identified all patients with more than 35 visits. This hyper-user (HU) cohort (n = 49) was compared to a randomly selected group of non-HU patients (n = 50) on the following measures: age, sex, insurance coverage, primary medical doctor (PMD), dwelling location, chief complaint, comorbidities, and disposition.

RESULTS

The HU group was significantly older (mean, 49.45 years) than the non-HU group (37.32 years) with a P < .0001. There was no difference between the groups in sex, insurance coverage, PMD, dwelling location, and disposition. A univariant logistical regression found that previous cardiovascular, genitourinary, or psychiatric disease were predictors of hyper-use.

CONCLUSIONS

The HU group is older and more likely to have a history of cardiovascular, genitourinary, and psychiatric disease but is similar to the non-HU group in other measured parameters. The HU group appears to have equal access to a PMD and is not more likely to be admitted to the hospital than the non-HU group.

Characteristics of non-urgent patients. Cross-sectional study of emergency department and primary care patients

OBJECTIVE

To describe characteristics of patients seeking medical attention for non-urgent conditions at an emergency department (ED) and patients who use non-scheduled services in primary healthcare.

DESIGN

Descriptive cross-sectional study.

SETTING

Primary healthcare centres and an ED with the same catchment area in Stockholm, Sweden.

PATIENTS

Non-scheduled primary care patients and non-referred non-urgent ED patients within a defined catchment area investigated by structured face-to-face interviews in office hours during a nine-week period.

MAIN OUTCOME MEASURES

Sociodemographic characteristics, chief complaints, previous healthcare use, perception of symptoms, and duration of symptoms before seeking care.

RESULTS

Of 924 eligible patients, 736 (80%) agreed to participate, 194 at the ED and 542 at nine corresponding primary care centres. The two groups shared demographic characteristics except gender. A majority (47%) of the patients at the primary care centres had respiratory symptoms, whereas most ED patients (52%) had digestive, musculoskeletal, or traumatic symptoms. Compared with primary care patients, a higher proportion (35%) of the ED patients had been hospitalized previously. ED patients were also more anxious about and disturbed by their symptoms and had had a shorter duration of symptoms. Both groups had previously used healthcare frequently.

CONCLUSIONS

Symptoms, previous hospitalization and current perception of symptoms seemed to be the main factors discriminating between patients studied at the different sites. There were no substantial sociodemographic differences between the primary care centre patients and the ED patients.

Socio-demographic and clinical characteristics of re-presentation to an Australian inner-city emergency department: implications for service delivery

Background

People who have complex health care needs frequently access emergency departments for treatment of acute illness and injury. In particular, evidence suggests that those who are homeless, or suffer mental illness, or have a history of substance misuse, are often repeat users of emergency departments. The aim of this study was to describe the socio-demographic and clinical characteristics of emergency department re-presentations. Re-presentation was defined as a return visit to the same emergency department within 28 days of discharge from hospital.

Methods

A retrospective cohort study was conducted of emergency department presentations occurring over a 24-month period to an Australian inner-city hospital. Characteristics were examined for their influence on the binary outcome of re-presentation within 28 days of discharge using logistic regression with the variable patient fitted as a random effect.

Results

From 64,147 presentations to the emergency department the re-presentation rate was 18.0% (n = 11,559) of visits and 14.4% (5,894/40,942) of all patients. Median time to re-presentation was 6 days, with more than half occurring within one week of discharge (60.8%; n = 6,873), and more than three-quarters within two weeks (80.9%; n = 9,151). The odds of re-presentation increased three-fold for people who were homeless compared to those living in stable accommodation (adjusted OR 3.09; 95% CI, 2.83 to 3.36). Similarly, the odds of re-presentation were significantly higher for patients receiving a government pension compared to those who did not (adjusted OR 1.73; 95% CI, 1.63 to 1.84), patients who left part-way through treatment compared to those who completed treatment and were discharged home (adjusted OR 1.64; 95% CI, 1.36 to 1.99), and those discharged to a residential-care facility compared to those who were discharged home (adjusted OR 1.46: 95% CI, 1.03 to 2.06).

Conclusion

Emergency department re-presentation rates cluster around one week after discharge and rapidly decrease thereafter. Housing status and being a recipient of a government pension are the most significant risk factors. Early identification and appropriate referrals for those patients who are at risk of emergency department re-presentation will assist in the development of targeted strategies to improve health service delivery to this vulnerable group.

Seven-year evolution of discharge diagnoses of emergency department users

OBJECTIVES

To describe the pattern of main diagnoses of persons discharged home from the emergency department.

METHODS

This was a descriptive study, using data from computer records of the emergency department at Landspitali University Hospital Hringbraut in Reykjavik, Iceland, over a 7-year period, 1995-2001. The main diagnoses of those discharged were registered according to the International Classification of Diseases and were transferred to the European shortlist, 'main categories'. Changes in the pattern of discharge diagnoses during the study period (1995-2001) were analyzed by calculating chi for the linear trend in each category.

RESULTS

The proportion of users discharged each year increased through the period. In 1995, 54.5% were sent home (not admitted to hospital) and in 2001, 72.5%. Diagnoses in the diagnostic category 'symptoms, signs, abnormal findings, and ill-defined causes', were the most frequently applied to both men and women; this was the classification in more than 20% of cases on average. The most significant change during the study period was the increase in frequency of this category among both men and women.

CONCLUSIONS

The proportion of emergency-department users, who are discharged without admission to hospital, increased and exceeded 70% of total cases received. On average, 20% of the discharge diagnoses were in the category 'symptoms, signs, abnormal findings, and ill-defined causes'. The pattern of discharge diagnoses can be assumed to reflect an increased load on the emergency department.

Demography of pediatric emergency care in Halifax, Canada

OBJECTIVES

Demography affects emergency department (ED) utilization and influences the health care needs of patients, yet the demographics of the caregivers who accompany children to pediatric EDs are not well described. The objective of this study was to provide a demographic description of this population. The hypothesis was that single parent status, annual income less than 20,000 dollars, and education no greater than high school constitute a social triad that might reduce the ability to provide health care for a sick child.

METHODS

Over a 1-month period, a convenience survey of caregivers who brought children to a pediatric ED was conducted. Twelve hundred surveys were distributed to 1733 eligible subjects. Social and economic determinants were captured, including age, gender, visible minority status, income group, employment, single parent status and education level.

RESULTS

In total, 1018 (85%) of 1200 surveys were returned - a population response rate of 59%. Single parent status, income less than 20,000 dollars/yr, and education no greater than high school were found to be risk factors for altered delivery of health care. Overall, 40.9% of caregivers had at least one risk factor, including 43.2% of women, 63.4% of those under 30 years of age, 65.1% of those with visible minority status, and 71.6% of women who were from a visible minority. In addition, 41.7% of single parents had no more than a high school education, and 75.7% of single parent families had incomes of less than 40,000 dollars per year.

CONCLUSIONS

It was found that a high level of educational, social and financial disadvantage in our population. These factors may adversely affect parental capability to provide health care at home for their child. The extent of this problem in other regions is not well defined and should be a focus of future research. It is recommended that inquiry into parental income, education and single parent status be a routine part of the history in pediatric emergency populations.

The emergency department for routine healthcare: race/ethnicity, socioeconomic status, and perceptual factors

Our objective was to study the role of race/ethnicity and socioeconomic status (SES) in the use of the emergency department (ED) as a source of routine healthcare. Adult patients presenting to an urban ED were surveyed. We assessed demographics, race/ethnicity, SES, and perceptional factors related to choosing the ED for the current visit. Stepwise logistic regression analyses were used to explore whether SES accounted for racial/ethnic trends in ED use. Of 1375 patients, 936 (68%) were enrolled. After controlling for insurance status, income, employment status, and education, neither race nor ethnicity remained a strong predictor of routine ED use. Race/ethnicity-based disparities in routine ED use were due to the confounding effects of SES. Programs to reduce inappropriate ED use must be sensitive to an array of complex socioeconomic issues and may necessitate a substantial paradigm shift in how acute care is provided in low SES communities.

Functional somatic symptoms in accident and emergency--An exploratory study

OBJECTIVES

To identify the extent and nature of functional somatic symptoms (FSS) in a UK Accident and Emergency (A&E) Department.

METHODS

A mixed method design was used. Data on the number and outcomes of attendances of patients who had attended A&E four or more times in a 6-month period, and who had not received a medical diagnosis were collected. Levels of anxiety and depression were explored and patients were invited to attend an interview with a clinical psychologist.

RESULTS

One hundred frequent attendees made 595 visits to A&E in 6 months, with 20% of visits resulting in a hospital admission. Participants revealed high levels of health anxiety, with over half of participants reporting a perceived link between psychological factors and their experience of symptoms. Over 80% of participants attending the interview wanted further help to manage their symptoms and health care utilisation.

CONCLUSIONS

Functional somatic symptoms are highly distressing for patients and place high demands on health care resources. An alternative care pathway to assess and manage FSS in A&E may need to be developed to help patients to manage their health anxiety.

Frequent users of Massachusetts emergency departments: a statewide analysis

STUDY OBJECTIVE

We describe the epidemiology of frequent users of emergency departments (EDs), using a statewide dataset derived from linked ED, observation stay, and inpatient hospital discharge databases.

METHODS

Unique patient identifiers were used to link visits across databases, encompassing all ED visits regardless of disposition. Individuals with 5 or more visits during a year were considered frequent users and were compared with infrequent users, as well as nonusers, using descriptive statistics.

RESULTS

Only 1% of Massachusetts residents were frequent users, but they made 17.6% of all ED visits in fiscal year 2003; 57.8% of residents used multiple EDs. Compared with infrequent users, frequent users were more likely to die at their last visit (2.6% of frequent users versus 1.1% of infrequent users), were hospitalized at higher rates (18.8% versus 14.2% of visits), and were transported more frequently by ambulance (18.6% versus 12.1% of visits). Two percent of the uninsured individuals were frequent users compared with 2.1% of Medicaid enrollees, 2.0% of Medicare enrollees, and 0.4% of privately insured individuals. Only 15% of frequent users were uninsured. Frequent ED use is typically temporary; just 28.4% of frequent users in fiscal year 2002 remained frequent users in fiscal year 2003.

CONCLUSION

Uninsured individuals are no more likely than publicly insured individuals to be ED frequent users and compose only 15% of them. Frequent users tend to be sicker than infrequent users, but most use the ED at high rates temporarily and visit the ED less frequently or not at all the following year.

Mortality of the users of a hospital emergency department

OBJECTIVE

To ascertain the annual number of users who were discharged home after visits to the emergency department (ED), grouped by age, sex, and number of visits during the calendar year, and to assess whether a higher number of visits to the department predicted a higher mortality.

METHODS

This was a retrospective cohort study, with follow up of cause specific mortality through a national registry, in the Reykjavik area of Iceland. In total, 19 259 patients who visited the ED during the period 1995-2001 and who were discharged home at the Landspítali University Hospital, Reykjavik, Iceland, were enrolled. The main outcome measures were the standardised mortality ratio, with expected number based on national mortality rates, and hazard ratio calculations using time dependent multivariate regression analysis.

RESULTS

The annual increase in visits to the ED among the patients discharged home was 7-14% per age group during the period 1995-2001, with the highest increase among older men. When emergency department users were compared with the general population, the standardised mortality ratio was 1.81 for men and 1.93 for women. Among those attending the ED two, three, or more times in a calendar year, the mortality rate was higher than among those coming only once in a year. The causes of death that led to the highest mortality among frequent users of the ED were neoplasm, ischaemic heart diseases, and external causes, particularly drug intoxication, suicides, and probable suicides.

CONCLUSIONS

The mortality of those who had used the ED and been discharged home was found to be higher than that of the general population. Frequent users of the ED had a higher mortality than those visiting the department no more than once a year. As the ED serves general medicine and surgery patients, not injuries, the high mortality due to drug intoxication, suicide, and probable suicide is interesting. Further studies are needed into the diagnosis at discharge of those frequently using the ED, in an attempt to understand and possibly prevent this marked mortality rate.

Psychiatric characteristics of frequent attenders at accident and emergency: a case register comparison with non frequent attenders

BACKGROUND AND AIMS

Patients attending Accident and Emergency (A&E) on a frequent basis consume a large amount of NHS resources and often frustrate health workers employed in the service. This audit aimed to identify the personal and psychiatric characteristics of these patients and highlight areas where intervention may be helpful.

METHODS AND RESULTS

Patients presenting to A &E more than 20 times in four years were comparison to non-frequent attenders using case register information. The study demonstrates that frequent attenders are well known to psychiatric services, but are not engaged in ongoing contact. This is not due to a difference in attendance rate between frequent attenders and controls but may represent reluctance for follow up either on the part of the patient or the psychiatrist.

CONCLUSIONS

These patients have a combination of physical, psychiatric and social pathologies and the services to address these needs does not seem to currently exist but should be considered.

Self-reported antibiotic compliance: Emergency department to general practitioner follow up

BACKGROUND

General practitioner (GP) follow up is important in the management of patients who are discharged from an ED.

OBJECTIVES

To determine the antibiotic compliance and GP follow-up compliance rates in a population of patients seen and discharged from the ED with an antibiotic prescription. To test the hypothesis that the ability to nominate a GP is associated with improved antibiotic and GP follow-up compliance.

DESIGN

A prospective cohort study enrolling consecutive adults who were discharged from the ED with antibiotic prescriptions over a 3 month period. Patients were divided into those who nominated a GP at the time of ED presentation and those who did not. Two weeks after enrollment, patients were contacted and asked standardized questions regarding compliance.

RESULTS

In total, 123 patients were enrolled into the study. Of patients 76% were able to nominate a GP upon ED presentation. Analysis revealed that those patients who were able to nominate a GP had better compliance to follow up instructions (85 vs 44%, P < 0.01) and improved antibiotic compliance (99 vs 88%, P = 0.01).

CONCLUSION

The majority of patients who were seen and discharged from the ED with an antibiotic prescription were able to nominate a GP and this was associated with improved follow-up compliance and antibiotic compliance. Improving follow-up compliance and thus the quality of patient care would involve identifying those patients who present to the ED who are unable to nominate a GP.

High mortality rates from medical problems of frequent emergency department users at a university hospital tertiary care centre

BACKGROUND

Frequent emergency department (ED) users are a nebulous group of patients. A high degree of psychiatric problems and higher than expected mortality from medical illness have been reported in this population.

STUDY OBJECTIVES

We sought to examine the pattern of ED use by adult patients identified as being heavy users of the ED, to examine their demographic characteristics and describe their clinical profile during a one-year period at one institution.

METHODS

This was a descriptive, retrospective study that took place in the ED of a 1000-bed teaching hospital in Barcelona, Spain, with a population in the metropolitan area of 1.5 million, which attends approximately 110,000 emergency visits per year, excluding paediatrics and obstetrics. The ED computer registration database was used to identify all patients presenting to the hospital ED more than 10 times in a one-year period from 1 January to 31 December 2000. A cohort composed of 86 patients fitting these inclusion criteria was identified as making 1263 (1.1%) of the total 109,857 ED visits. All medical records for each patient were reviewed to determine the primary reason for repeated ED visits.

RESULTS

Of the 86 patients enrolled, 58 were men (67.4%). The mean age was 55 years (range 18-91), but only six patients (6.9%) were older than 80 years. The median number of ED visits per patient was 14 throughout the year. Forty-five of the patients (52.3%) were classified as having primarily medical reasons for presenting to the ED, with diagnoses such as shortness of breath and chest pain being the chief symptoms. Seventeen patients (19.7%) had a surgical problem as the cause of their ED visits, and eight (9.3%) had psychiatric problems contributing to the ED visits. Other major reasons for presentation to the ED were as follows: ophthalmic, eight patients (9.3%); otolaryngological, four patients (4.6%); and trauma, four patients (4.6%). A total of 982 (77.8%) of the total ED visits resulted in home discharge. Hospital emergency admissions and outpatient clinics diversions occurred in 106 (8.3%) and 71 (5.6%) ED visits, respectively. The mortality rate was as high as 18.6% (16 frequent ED users died).

CONCLUSION

These data show that there is a high incidence of medical problems in frequent ED users and a high incidence of mortality in patients with heavy ED use.

Predictors of medication refill–seeking behavior in the ED

OBJECTIVE

Determine predictors of medication refill-seeking behavior in ED patients with chronic illness.

METHODS/DESIGN

Prospective cross-sectional ED survey conducted for 6 weeks.

SETTING

Public hospital ED (>140,000 visits per year).

SUBJECTS

ED patients (>18 years) taking chronic medications for congestive heart failure, diabetes, and/or hypertension.

RESULTS

Of 1168 patients surveyed, 344 (29%) presented to the ED secondary to running out of medications and requiring a medication refill. Univariate predictors included age younger than 50 years, non-Hispanic ethnicity, low income (<5000 dollars per year), self-pay payor status, and being told to call a primary care physician before medication would be refilled. Lack of knowledge about refill or pharmacy numbers on the medication bottle resulted in patients being more than twice as likely to be in the ED for a medication refill (odds ratio 2.4 [1.6, 3.6] and 2.0 [1.3, 2.9], respectively).

CONCLUSION

Presenting for medication refills is common in ED patients with chronic illness.

The heaviest repeat users of an inner city emergency department are not general practice patients

OBJECTIVE

To test the hypothesis that frequent attenders to the ED are suitable for diversion to general practice.

METHODS

A retrospective review of a computerized database for the top 500 frequent presenters to an inner city adult teaching hospital ED.

RESULTS

Five hundred patients presented 12,940 times, an average of 26 times per patient, accounting for (8.4% [8.3, 8.6]) of total ED presentations over 64 months. There were 7699 (59.5% [58.7, 60.4]) presentations deemed appropriate for ED. Of the remaining 5241 presentations, 1553 (29.6% [28.4, 30.9]) were between 22.00 and 07.00 hours, outside the hours of most actual or proposed primary care clinics. This left 3688 (28.5% [27.7, 29.3]) presentations by the heaviest users of the ED as potentially appropriate for general practice. Of these presentations 1507 (40.9% [39.3, 42.5]) were by people who were homeless. A total of 2574 (69.8% [68.3, 71.3]) had pre-existing case management, either by the hospital or another service. Nine hundred and seventy-eight (26.5% [25.1, 28.0]) had primary psychiatric or altered conscious states due to drugs and alcohol as the presenting problem. At least 90 of these 500 frequently presenting patients died during the study period.

CONCLUSION

The majority of the presentations by the heaviest users of an ED in a city teaching hospital are not suitable for general practice. Attempting diversion of the heaviest repeat ED users to a general practice in this setting may not be successful due to the severity, acuity and nature of casemix of the presentations and would have minimal impact on crowding in similar emergency departments.

Variations in the use of emergency departments in Alberta's Capital Health region 1998-2000

The objectives of this study were to describe the utilization of emergency departments in the Capital Health region, Alberta, between 1998 and 2000, and temporal variations in emergency department utilization by month, day of week, and time of day in 2000. Between 1998 and 2000, the annual number of visits to emergency departments in the region increased by six percent. The mean length of stay, median length of stay and the number of patients who left without being seen increased by six minutes, eight minutes, and 4,442 patients respectively. Variations in the number of visits, mean and median lengths of stay, and numbers of patients who left without being seen by month, day of week, and time of day were modest except for patients who left without being seen. Service pressures in Capital Health emergency departments continue to exist. Temporal variations in service pressures were small. Causes of emergency department pressures are multiple and interrelated. Therefore, system-wide changes should be considered in addressing emergency department pressures.

Predictors and outcomes of frequent emergency department users

OBJECTIVE

To identify predictors and outcomes associated with frequent emergency department (ED) users.

METHODS

Cross-sectional intake surveys, medical chart reviews, and telephone follow-up interviews of patients presenting with selected chief complaints were performed at five urban EDs during a one-month study period in 1995. Frequent use was defined by four or more self-reported, prior ED visits. Multivariate logistic regression identified predictors of frequent ED visitors from five domains (demographics, health status, health access, health care preference, and severity of acute illness). Associations between high use and selected outcomes were assessed with logistic regression models.

RESULTS

All study components were completed by 2,333 of 3,455 eligible patients (67.5%). Demographics predicting frequent use included being a single parent, single or divorced marital status, high school education or less, and income of less than $10,000 (1995). Health status predictors included hospitalization in the preceding three months, high ratings of psychological distress, and asthma. Health access predictors included identifying an ED or a hospital clinic as the primary care site, having a primary care physician (PCP), and visiting a PCP in the past month. Choosing the ED for free care was the only health preference predictive of heavy use. Illness severity measures were higher in frequent visitors, although these were not independently predictive in the multivariate model. Outcomes correlated with heavy use include increased hospital admissions, higher rates of ED return visits, and lower patient satisfaction, but not willingness to return to the ED or follow-up with a doctor.

CONCLUSIONS

Frequent ED visits are associated with socioeconomic distress, chronic illness, and high use of other health resources. Efforts to reduce ED visits require addressing the unique needs of these patients in the emergency and primary care settings.

Frequent attenders to an emergency department: a study of primary health care use, medical profile, and psychosocial characteristics

STUDY OBJECTIVE

We describe, in comparison with a control group, frequent attenders to an emergency department in terms of their general health service use and their clinical, psychological, and social profiles.

METHODS

One hundred frequent attenders (those who had made > or =4 visits in the previous year) and 100 nonfrequent attenders matched for sex, age, and triage category were interviewed in the ED. Data were gathered on health service use, mental health (by using the General Health Questionnaire-12 item), and perceived social support (by using the Multidimensional Scale of Perceived Social Support). Patients' general practitioners were contacted to validate attendance data. Medical charts were searched for evidence of psychological problems and alcohol or drug abuse.

RESULTS

In the overall sample of 200 patients, 32% were female, and the mean age was 55 years (SD 20). Frequent attenders had made more visits to their general practitioner in the past year compared with control patients (median 12 versus 3 visits); a higher proportion of frequent attenders had used public health nursing services, community welfare services, social work services, addiction counseling, and psychiatric services in the past year. Frequent attenders had made more other hospital visits and had spent more nights in the hospital than control patients. General Health Questionnaire-12 item scores were higher for frequent attenders than control patients, indicating poorer mental health. Frequent attenders had lower levels of perceived social support.

CONCLUSION

Frequent attenders to the ED are also heavy users of general practice services, other primary care services, and other hospital services. General Medical Services-eligible patients (84% of frequent attenders) frequently attend the ED, even though they have free access to primary care. Frequent attenders are a psychosocially vulnerable group, and service providers and policy makers need to take account of this vulnerable patient profile as they endeavor to meet their service needs.

Inadequate nursing care in an emergency care unit in Sweden. Lack of a holistic perspective

The aim of this case study has been to analyze factors that hinder the provision of adequate nursing care in one emergency care unit (ECU). The research question was, What are the conditions that explain the provision of inadequate nursing care in an ECU with reported problems concerning caring attitudes? The design of the study was exploratory and interpretive within a hermeneutic tradition. Nurses were interviewed, and field notes were made from participant observations of routine work and staff meetings. An interpreted whole revealed a lack of a holistic perspective. The difficulty of these nurses in accomplishing a holistic perspective seemed to be due to overvaluation of measurable tasks, such as medical interventions, and undervaluation of nonmeasurable tasks, such as caring. As a consequence, caring interventions failed to strengthen the nurses' self-esteem in the same high degree as medical tasks.

Repeated use of the emergency department: qualitative study of the patient's perspective

OBJECTIVE

To explore what lies behind repeated emergency department (ED) use, from the patients' own perspectives.

METHODS

Qualitative study based on in depth interviews with frequent users of the ED at the Huddinge University Hospital, Sweden. Ten adult patients having visited the ED 6-17 times in the previous 12 months were interviewed. The personal meaning they attached to the symptoms and their encounters at the ED were inductively analysed, thereby relating patient behaviour to life conditions.

RESULTS

The frequent ED visitors perceive pain or other symptoms as a threat to life or to personal autonomy. Irrespective of whether or not the patients relate their health problems to a traumatic event, overwhelming anxiety compels them to seek urgent help. Clear cut diagnoses are seldom mentioned. Although none of the patients is homeless or totally lacking in means, the narratives reveal struggles with adverse life circumstances and medical, psychological and/or social problems, including alcohol or other substance misuse. Occasional referrals from the ED to a psychiatrist seem not to lead to any continuous treatment or to a change in the patients' health seeking behaviour. Satisfaction with care becomes adversely affected when the patients perceive that the ED staff classifies their use of the ED as inappropriate or when their symptoms are belittled.

CONCLUSIONS

From their own perspectives, frequent ED visitors are in need of urgent care. It is particularly important to these patients that the personal meaning they attach to their symptoms is attended to and respected by the ED staff.

Frequent use of the hospital emergency department is indicative of high use of other health care services

STUDY OBJECTIVE

We sought to determine the proportion of emergency department patients who frequently use the ED and to compare their frequency of use of other health care services at non-ED sites.

METHODS

A computerized patient database covering all ambulatory visits and hospital admissions at all care facilities in the county of Stockholm, Sweden, was used. Frequent ED patients were defined as those making 4 or more visits in a 12-month period.

RESULTS

Frequent users comprised 4% of total ED patients, accounting for 18% of the ED visits. The ED was the only source of ambulatory care for 13% of frequent versus 27% of rare ED users (1 ED visit). Primary care visits were made by 72% of frequent ED users versus 57% by rare ED visitors. The corresponding figures for hospital admission were 80% and 36%, respectively. Frequent ED visitors were also more likely to use other care facilities repeatedly: their odds ratio (adjusted for age and sex) was 3.43 (95% confidence interval [CI] 3.10 to 3.78) for 5 or more primary care visits and 29.98 (95% CI 26.33 to 34.15) for 5 or more hospital admissions. In addition, heavy users had an elevated mortality (standardized mortality ratio 1.55; 95% CI 1.26 to 1.90).

CONCLUSION

High ED use patients are also high users of other health care services, presumably because they are sicker than average. A further indication of serious ill health is their higher than expected mortality. This knowledge might be helpful for care providers in their endeavors to find appropriate ways of meeting the needs of this vulnerable patient category.

Psychiatric status, somatisation, and health care utilization of frequent attenders at the emergency department: a comparison with routine attenders

Seventy-seven frequent attenders at an emergency department (ED) in an inner-city hospital in the UK (defined as seven or more visits in the previous 12 months) were compared with 182 patients who were attending the same department on a routine basis. Patients completed the Schedules for Clinical Assessment in Neuropsychiatry (SCAN) and the Short Form (SF)-36. Information was obtained on 64% of the frequent attenders and 45% underwent a detailed psychiatric assessment. Of the frequent attenders, 45% had psychiatric disorder and 49% had some form of an alcohol-related disorder. Compared with routine attenders, frequent attenders reported lower health status, had more psychiatric disorder (odds ratio: OR=8.2, 95% confidence interval: CI=3.8--18.1), had more general hospital admissions (OR=19.9, 95% CI=8.3--47.8), more psychiatric admissions (OR=167.5, 95% CI=9.5--2959.0), and more GP visits (95% CI for difference=-10.2 to -5.7). There was no evidence that frequent attenders had more somatisation than routine attenders. Specific treatment and management strategies need to be developed for this group of patients, although a substantial proportion may be difficult to engage in the treatment process.
