Case management of patients who frequently present to a Scottish emergency department

Assertive community treatment for high-utilizing alcohol misuse patients: a before-and-after cohort study protocol

BACKGROUND

The challenge posed by Alcohol-Related Frequent Attenders (ARFAs) in Emergency Departments (EDs) is growing in Singapore, marked by limited engagement with conventional addiction treatment pathways. Recognizing this gap, this study aims to explore the potential benefits of Assertive Community Treatment (ACT) - an innovative, community-centered, harm-reduction strategy-in mitigating the frequency of ED visits, curbing Emergency Medical Services (EMS) calls, and uplifting health outcomes across a quartet of Singaporean healthcare institutions.

METHODS

Employing a prospective before-and-after cohort design, this investigation targeted ARFAs aged 21 years and above, fluent in English or Mandarin. Eligibility was determined by a history of at least five ED visits in the preceding year, with no fewer than two due to alcohol-related issues. The study contrasted health outcomes of patients integrated into the ACT care model versus their experiences under the exclusive provision of standard emergency care across Hospitals A, B, C and D. Following participants for half a year post-initial assessment, the evaluation metrics encompassed socio-demographic factors, ED, and EMS engagement frequencies, along with validated health assessment tools, namely Christo Inventory for Substance-misuse Services (CISS) scores, University of California, Los Angeles (UCLA) Loneliness scores, and Centre for Epidemiologic Studies Depression Scale Revised (CESD-R-10) scores.

DISCUSSION

Confronted with intricate socio-economic and medical challenges, the ARFA cohort often grapples with heightened vulnerabilities in relation to alcohol misuse. Pioneering the exploration of ACT's efficacy with ARFAs in a Singaporean context, our research is anchored in a patient-centered approach, designed to comprehensively address these multifaceted clinical profiles. While challenges, like potential high attrition rates and sporadic data collection, are anticipated, the model's prospective contribution towards enhancing patient well-being and driving healthcare efficiencies in Singapore is substantial. Our findings have the potential to reshape healthcare strategies and policy recommendations.

Appropriateness of frequent use of emergency departments: A retrospective analysis in Rome, Italy

Background

Frequent users (FUs) are patients who repeatedly and inappropriately visit the emergency department (ED) for low-grade symptoms that could be treated outside the hospital setting. This study aimed to investigate the phenomenon of the FU in Rome by profiling such users and analyzing ED attendance by FUs.

Methods

The analysis was carried out for attendance in 2021 at 15 EDs in the Local Health Authority Roma 1 geographical area. A digital app collected data, including information on the following variables: number of attendance, demographic characteristics, emergency medical service (EMS) usage, triage code, and appropriateness of attendance. COVID-19 diagnosis was also studied to analyze any possible influence on ED attendance. Differences between FUs and non-FUs were investigated statistically by t-test and chi-square test. Univariate analysis and multivariable logistic regression were performed to analyze the associated factors.

Results

A total of 122,762 ED attendance and 89,036 users were registered. The FU category represented 2.9% of all users, comprising 11.9% of total ED attendance. There was a three times higher frequency of non-urgent codes in attendance of FU patients (FU: 9.7%; non-FU: 3.2%). FUs were slightly more likely to have used the EMS (13.6% vs. 11.4%) and had a lower frequency of appropriate ED attendance (23.8% vs. 27.0%). Multivariate logistic analysis confirmed a significant effect of triage code, gender, age, EMS usage, and COVID-19 diagnosis for the appropriateness of attendance. The results were statistically significant (p < 0.001).

Conclusion

The FU profile describes mostly non-urgent and inappropriate attendance at the ED, including during the COVID-19 pandemic. This study represents an important tool for strengthening preventive policies outside the hospital setting. The Italian National Recovery and Resilience Plan represents an excellent opportunity for the development of new strategies to mitigate the phenomenon of FUs.

Strategies for utilisation management of hospital services: a systematic review of interventions

Background

To achieve efficiency and high quality in health systems, the appropriate use of hospital services is essential. We identified the initiatives intended to manage adult hospital services and reduce unnecessary hospital use among the general adult population.

Methods

We systematically reviewed studies published in English using five databases (PubMed, ProQuest, Scopus, Web of Science, and MEDLINE via Ovid). We only included studies that evaluated interventions aiming to reduce the use of hospital services or emergency department, frequency of hospital admissions, length of hospital stay, or the use of diagnostic tests in a general adult population. Studies reporting no relevant outcomes or focusing on a specific patient population or children were excluded.

Results

In total, 64 articles were included in the systematic review. Nine utilisation management methods were identified: care plan, case management, care coordination, utilisation review, clinical information system, physician profiling, consultation, education, and discharge planning. Primary case management was shown to effectively reduce emergency department use. Care coordination reduced 30-day post-discharge hospital readmission or emergency department visit rates. The pre-admission review program decreased elective admissions. The physician profiling, concurrent review, and discharge planning effectively reduced the length of hospital stay. Twenty three studies that evaluated costs, reported cost savings in the hospitals.

Conclusions

Utilisation management interventions can decrease hospital use by improving the use of community-based health services and improving the quality of care by providing appropriate care at the right time and at the right level of care.

Impact of a case-management intervention for reducing emergency attendance on primary care: randomised control trial

BACKGROUND

The impact on primary care workload of case-management interventions to reduce emergency department (ED) attendances is unknown.

AIM

To examine the impact of a telephone-based case-management intervention targeting people with high ED attendance on primary care use.

DESIGN AND SETTING

A single-site data extract from a larger randomised control trial, using the patient-level data from primary care electronic health records (2015-2020), was undertaken.

METHOD

A total of 363 patients at high risk of ED usage were randomised to receive a 6-month case-management intervention (253 patients) or standard care (110 patients). Poisson regression models were used to calculate monthly rates of primary care use over time for the 2 years post-randomisation, comparing both arms. Usage was subclassified into face-to-face, telephone, letter, and community and secondary care referrals, stratified by patient demographics.

RESULTS

No significant difference was found in the mean annual rate of primary care events between the intervention and control arms (P = 0.70). Secondary care referrals saw a 26% reduction in the mean annual referral rate (incident rate ratio [IRR] 0.74, 95% confidence interval [CI] = 0.64 to 0.86, P<0.001) and letters sent increased by 6% in the intervention arm compared with the control arm (IRR 1.06, 95% CI = 1.01 to 1.11, P = 0.01). In the case-managed arm, in patients aged ≥80 years there was a 33% increase in primary care usage (IRR 1.33, 95% CI = 1.28 to 1.40, P<0.001); with a corresponding 10% decrease in patients aged <80 years when compared with controls (IRR 0.90, 95% CI = 0.87 to 0.92, P<0.001).

CONCLUSION

A targeted case-management intervention to reduce ED attendances did not increase overall primary care use. Redistribution of usage is seen among some patient groups, particularly older people, which may have important implications for primary healthcare planning.

The analysis of the geographical distribution of emergency departments' frequent users: a tool to prioritize public health policies?

Background

The individual factors associated to Frequent Users (FUs) in Emergency Departments are well known. However, the characteristics of their geographical distribution and how territorial specificities are associated and intertwined with ED use are limited. Investigating healthcare use and territorial factors would help targeting local health policies. We aim at describing the geographical distribution of ED’s FUs within the Paris region.

Methods

We performed a retrospective analysis of all ED visits in the Paris region in 2015. Data were collected from the universal health insurance’s claims database. Frequent Users (FUs) were defined as having visited ≥3 times any ED of the region over the period. We assessed the FUs rate in each geographical unit (GU) and assessed correlations between FUs rate and socio-demographics and economic characteristics of GUs. We also performed a multidimensional analysis and a principal component analysis to identify a typology of territories to describe and target the FUs phenomenon.

Results

FUs accounted for 278,687 (11.7%) of the 2,382,802 patients who visited the ED, living in 232 GUs. In the region, median FUs rate in each GU was 11.0% [interquartile range: 9.5–12.5]. High FUs rate was correlated to the territorial markers of social deprivation. Three different categories of GU were identified with different profiles of healthcare providers densities.

Conclusion

FUs rate varies between territories and is correlated to territorial markers of social deprivation. Targeted public policies should focus on disadvantaged territories.

Reducing Frequency of Emergency Department and Inpatient Visits Through Focused Case Management

PURPOSE OF STUDY

To evaluate whether the Oklahoma State University (OSU) Health Access Network's (HAN's) case management program is effective in reducing the attendance of frequent users to the emergency department (ED) and inpatient department.

PRIMARY PRACTICE SETTING

This is a 2-year retrospective pre/post-case management analysis. Emergency department usage data from 2013 to 2016 of the OSU HAN contracted clinics are used in this study. This study involves case management interventions for high ED users and high-risk patients. The patients in the study must be enrolled in SoonerCare choice to be case managed.

METHODOLOGY AND SAMPLE

Patients who visited the ED 3 times or more in 12 months prior to their HAN enrollment and patients with 12 months of data preenrollment and postenrollment were included in the study. A historical control was used to compare ED and inpatient use per patient per month pre- and post-HAN case management. Chi-square and Wilcoxon's signed-rank tests were used to assess the data.

RESULTS

A total of 29 patients met the inclusion criteria. The number of ED and inpatient visits was reduced after HAN intervention (181 vs. 110, p < .001; 35 vs. 11, p < .001). The ED and inpatient use per patient per month reduced significantly from 0.52 to 0.31 (p < .001) and 0.10 to 0.03 (p < .01), respectively.

IMPLICATIONS FOR CASE MANAGEMENT PRACTICE

This study suggests that continuous case management and implementation of various care plans with frequent follow-up are effective in reducing the cost of care and subsequent ED and inpatient visits.

Ambulante Entlassung aus der Notfallstation

Die Entlassung aus der Notfallstation in die ambulante Weiterbehandlung stellt den größten Teil des „outflow“ aus den Notfallstationen dar. Um die steigende Anzahl der Patienten sicher in die ambulante Betreuung zu entlassen, sollte der Entlassungsprozess ebenso wie Diagnostik und Therapie einen Platz im Behandlungsplan einnehmen. Werden die Maßnahmen zur Sicherung einer guten Kommunikation und Instruktion der Patienten vor der Entlassung richtig umgesetzt, können Patientensicherheit und medizinisches Outcome verbessert werden. Diese Strategie unterstützt eine patientenzentrierte Behandlung und reduziert oftmals eine ungeplante Wiedervorstellung und folglich Gesundheitskosten. Der nachfolgende Text basiert auf der Veröffentlichung „Improving the emergency department discharge process: environmental scan report“ des Armstrong Institute for Patient Safety and Quality an der der Johns Hopkins University School of Medicine für die Agency for Healthcare Research and Quality in den Vereinigten Staaten. Hier werden Begriffe definiert, die eine qualitativ hochwertige Entlassung ausmachen; welche Risikofaktoren eine qualitativ schlechte Entlassung verursachen können und welche Maßnahmen die Qualität der Entlassung erhöhen. Natürlich sollte man dabei die Unterschiede im Setting und im Gesundheitssystem sowie der Notfallstationen bedenken und an die eigenen Gegebenheiten anpassen.

Prevalence and patterns of hospital use for people with frequent alcohol-related hospital admissions, compared to non-alcohol and non-frequent admissions: a cohort study using routine administrative hospital data

AIMS

This study compared prevalence and hospital use among individuals frequently admitted to hospital in England with wholly attributable alcohol-related diagnoses (WAAD), known as alcohol-related frequent attenders (ARFAs), with those of non-alcohol frequent attenders (NAFAs), non-frequent alcohol attenders (ARNFAs) and non-alcohol non-frequent attenders (NANFAs).

DESIGN

Cross-sectional and longitudinal analyses of 5 years of England's Hospital Episode Statistics (HES).

SETTING

Hospital inpatients in England, UK, 2011-16.

PARTICIPANTS

Two cohorts (2011/12 = 489 580/7 654 944 patients and 2015/16 = 490 384/7 660 108 patients) were selected from all adult patients aged ≥ 18 years, treated in English hospitals between 1 April 2011 and 31 March 2016. Patients were categorized as having alcohol-related admissions if diagnoses included a WAAD (ICD-10 classification, WHO, 2016) and frequent admissions if they had more than three hospital admissions during a single HES year.

MEASUREMENTS

Prevalence of ARFA, number of admissions (spells), occupied bed-days (OBDs), average length of stay (ALOS) and total admission costs over 5 years were compared among ARFAs, ARNFAs, NAFAs and NANFAs.

FINDINGS

On average, 0.7% of people admitted to hospital per annum in England 2011-15 were ARFAs and more than a quarter of all frequent attenders (for all causes) to hospitals had a wholly attributable alcohol diagnosis on admission. ARFAs had longer ALOS than the other patient groups [5.55 days versus ARNFA 4.7, NAFA 3.39 and NANFA 2.57 days, F = 1088.37 (3, 488 570, P < 0.001)] in the 2015/16 index year; but fewer spells than NAFAs [5.38 ARFAs versus 5.98 NAFAs, F = 20 536.25 (3, 490 380) P < 0.001]. The ARFA cohort reduced in size (from 51 934 ARFAs to 20 548) in the course of 5 years. ARFAs had the highest average total cost of admissions per person over 5 years at £38 189.

CONCLUSIONS

People with repeated admissions for alcohol-related problems in England appear to be a high-cost, high-need, complex group of patients that makes up more than a quarter of the country's alcohol admissions.

Strategies for case management in transitional care in emergency services: scoping review

OBJECTIVE

to map and synthesize the strategies implemented for case management in transitional care for patients with complex needs in emergency services.

METHOD

a scoping review conducted under the Joanna Briggs Institute guidance. Twenty-three studies were analyzed, with different methodological designs, on the strategies used in case management involving adult and elderly populations in emergency services.

RESULTS

the main strategies employed were patient risk stratification screening/identification, care management plan, coordination of care through multidisciplinary activities, support for the transition process, continuous patient monitoring, and follow-up.

FINAL CONSIDERATIONS

these strategies used structured approaches to care in emergency services to promote support for self-management and effective transitional care for people with complex needs, ensuring comprehensiveness, coordination, and continuity of care.

CONECT-6: a case-finding tool to identify patients with complex health needs

Background

Early identification of patients with chronic conditions and complex health needs in emergency departments (ED) would enable the provision of services better suited to their needs, such as case management. A case-finding tool would ultimately support ED teams to this end and could reduce the cost of services due to avoidable ED visits and hospitalizations. The aim of this study was to develop and validate a short self-administered case-finding tool in EDs to identify patients with chronic conditions and complex health needs in an adult population.

Methods

This prospective development and initial validation study of a case-finding tool was conducted in four EDs in the province of Quebec (Canada). Adult patients with chronic conditions were approached at their third or more visit to the ED within 12 months to complete a self-administered questionnaire, which included socio-demographics, a comorbidity index, the reference standard INTERMED self-assessment, and 12 questions to develop the case-finding tool. Significant variables in bivariate analysis were included in a multivariate logistic regression analysis and a backward elimination procedure was applied. A receiver operating characteristic (ROC) curve was developed to identify the most appropriate threshold score to identify patients with complex health needs.

Results

Two hundred ninety patients participated in the study. The multivariate analysis yielded a six-question tool, COmplex NEeds Case-finding Tool – 6 (CONECT-6), which evaluates the following variables: low perceived health; limitations due to pain; unmet needs; high self-perceived complexity; low income; and poor social support. With a threshold of two or more positive answers, the sensitivity was 90% and specificity 66%. The positive and negative predictive values were 49 and 75% respectively.

Conclusions

The case-finding process is the essential characteristic of case management effectiveness. This study presents the first case-finding tool to identify adult patients with chronic conditions and complex health needs in ED.

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.

Case Management in Primary Care for Frequent Users of Health Care Services: A Realist Synthesis

PURPOSE

Case management (CM) is a promising intervention for frequent users of health care services. Our research question was how and under what circumstances does CM in primary care work to improve outcomes among frequent users with chronic conditions?

METHODS

We conducted a realist synthesis, searching MEDLINE, CINAHL, Embase, and PsycINFO (1996 to September 2017) for articles meeting the following criteria: (1) population: adult frequent users with chronic disease, (2) intervention: CM in a primary care setting with a postintervention evaluation, and (3) primary outcomes: integration of services, health care system use, cost, and patient outcome measures. Academic and gray literature were evaluated for relevance and robustness. Independent reviewers extracted data to identify context, mechanism, and outcome (CMO) configurations. Analysis of CMO configurations allowed for the modification of an initial program theory toward a refined program theory.

RESULTS

Of the 9,295 records retrieved, 21 peer-reviewed articles and an additional 89 documents were retained. We evaluated 19 CM interventions and identified 11 CMO configurations. The development of a trusting relationship fostering patient and clinician engagement in the CM intervention was recurrent in many CMO configurations.

CONCLUSION

Our refined program theory proposes that in the context of easy access to an experienced and trusted case manager who provides comprehensive care while maintaining positive interactions with patients, the development of this relationship fosters the engagement of both individuals and yields positive outcomes when the following mechanisms are triggered: patients and clinicians feel supported, respected, accepted, engaged, and committed; and patients feel less anxious, more secure, and empowered to self-manage.

Characteristics of Case Management in Primary Care Associated With Positive Outcomes for Frequent Users of Health Care: A Systematic Review

PURPOSE

Case management (CM) interventions are effective for frequent users of health care services, but little is known about which intervention characteristics lead to positive outcomes. We sought to identify characteristics of CM that yield positive outcomes among frequent users with chronic disease in primary care.

METHODS

For this systematic review of both quantitative and qualitative studies, we searched MEDLINE, CINAHL, Embase, and PsycINFO (1996 to September 2017) and included articles meeting the following criteria: (1)population: adult frequent users with chronic disease, (2)intervention: CM in a primary care setting with a postintervention evaluation, and (3)primary outcomes: integration of services, health care system use, cost, and patient outcome measures. Independent reviewers screened abstracts, read full texts, appraised methodologic quality (Mixed Methods Appraisal Tool), and extracted data from the included studies. Sufficient and necessary CM intervention characteristics were identified using configurational comparative methods.

RESULTS

Of the 10,687 records retrieved, 20 studies were included; 17 quantitative, 2 qualitative, and 1 mixed methods study. Analyses revealed that it is necessary to identify patients most likely to benefit from a CM intervention for CM to produce positive outcomes. High-intensity intervention or the presence of a multidisciplinary/interorganizational care plan was also associated with positive outcomes.

CONCLUSIONS

Policy makers and clinicians should focus on their case-finding processes because this is the essential characteristic of CM effectiveness. In addition, value should be placed on high-intensity CM interventions and developing care plans with multiple types of care providers to help improve patient outcomes.

Age differences in emergency department utilization and repeat visits among patients with opioid use disorder at an urban safety-net hospital: A focus on young adults

BACKGROUND

Opioid use disorder (OUD) among young adults from ages 18 to 25 years is increasing in the United States. Emergency departments (EDs) are recognized as major sources of care for patients with OUD, but questions remain about ED utilization among this population. We examined the demographics and ED utilization patterns at an urban safety-net hospital with a focus on young adults to inform intervention development.

METHODS

We extracted demographic and clinical data from electronic medical records of patients ages 18 to 64 years diagnosed with OUD between 2013 and 2017. Descriptive statistics were assessed, including race/ethnicity, sex, insurance, other substance use disorder and mental health diagnoses, and ED utilization patterns by age group. Univariable and multivariable logistic regressions were performed to analyze the associations between age and ED utilization patterns.

RESULTS

Among 12,025 OUD patients in the sample, 30% had an ED visit with a primary diagnosis of OUD. Among those who had an ED visit, 48% had at least one additional ED visit within a year. The probability of ED visits (adjusted odds ratio [AOR]:5.04; 95% confidence interval [CI]:4.14-6.13) and repeat ED visits (AOR:3.28; CI:2.53-4.26) were significantly higher among young adults (18-25 years) compared to the oldest age group (56-64 years).

CONCLUSIONS

Compared to older adults, young adults with OUD are more likely to use the ED and to have repeat ED visits. The identification of youth-tailored interventions in the ED within broader efforts to address the opioid epidemic should be an urgent priority.

Here one year, gone the next? Investigating persistence of frequent emergency department attendance: a retrospective study in Australia

OBJECTIVES

Patients are presenting to emergency departments (EDs) with increasing complexity at rates beyond population growth and ageing. Intervention studies target patients with 12 months or less of frequent attendance. However, these interventions are not well targeted since most patients do not remain frequent attenders. This paper quantifies temporary and ongoing frequent attendance and contrasts risk factors for each group.

DESIGN

Retrospective population-based study using 10 years of longitudinal data.

SETTING

An Australian geographic region that includes metropolitan and rural EDs.

PARTICIPANTS

332 100 residents visited any ED during the study period.

MAIN OUTCOME MEASURE

Frequent attendance was defined as seven or more visits to any ED in the region within a 12-month period. Temporary frequent attendance was defined as meeting this threshold only once, and ongoing more than once. Risk factors for temporary and ongoing frequent attenders were identified using logistic regression models for adults and children.

RESULTS

Of 8577 frequent attenders, 80.1% were temporary and 19.9% ongoing (12.9% repeat, 7.1% persistent). Among adults, ongoing were more likely than temporary frequent attenders to be young to middle aged (aged 25-64 years), and less likely to be from a high socioeconomic area or be admitted. Ongoing frequent attenders had higher rates of non-injury presentations, in particular substance-related (OR=2.5, 99% CI 1.1 to 5.6) and psychiatric illness (OR=2.9, 99% CI 1.8 to 4.6). In comparison, children who were ongoing were more likely than temporary frequent attenders to be aged 5-15 years, and were not more likely to be admitted (OR=2.7, 99% CI 0.7 to 10.9).

CONCLUSIONS

Future intervention studies should distinguish between temporary and ongoing frequent attenders, develop specific interventions for each group and include rigorous evaluation.

Social factors in frequent callers: a description of isolation, poverty and quality of life in those calling emergency medical services frequently

Background

Frequent users of emergency medical services (EMS) comprise a disproportionate percentage of emergency department (ED) visits. EDs are becoming increasingly overwhelmed and a portion of use by frequent callers of EMS is potentially avoidable. Social factors contribute to frequent use however few studies have examined their prevalence. This study aims to describe social isolation/loneliness, poverty, and quality of life in a sample of frequent callers of EMS in the Hamilton region, a southern Ontario mid-sized Canadian city.

Study design

Cross-sectional quantitative study.

Methods

We surveyed people who called EMS five or more times within 12 months. A mailed self-administered survey with validated tools, and focused on four major measures: demographic information, social isolation, poverty, and quality of life.

Results

Sixty-seven frequent EMS callers revealed that 37–49% were lonely, 14% had gone hungry in the preceding month, and 43% had difficulties making ends meet at the end of the month. For quality of life, 78% had mobility problems, 55% had difficulty with self-care, 78% had difficulty with usual activities, 87% experienced pain/discomfort, and 67% had anxiety/depression. Overall quality adjusted life years value was 0.53 on a scale of 0 to 1. The response rate was 41.1%.

Conclusions

Loneliness in our participants was more common than Hamilton and Canadian rates. Frequent EMS callers had higher rates of poverty and food insecurity than average Ontario citizens, which may also act as a barrier to accessing preventative health services. Lower quality of life may indicate chronic illness, and users who cannot access ambulatory care services consistently may call EMS more frequently. Frequent callers of EMS had high rates of social loneliness and poverty, and low quality of life, indicating a need for health service optimization for this vulnerable population.

2.5 years on: what are the effects of a 'frequent attenders' service in the Emergency Department?

This study focused on an evaluation over 2.5 years to establish if a frequent attenders' service in an Emergency Department (ED) impacted on the overall number of patients attending as well as the numbers of their attendances. For this, three patient lists from April-September 2015 and three lists from a matched period in 2017 were randomly selected and the two samples compared. Results showed both a reduction in the number of total patients identified as frequent attenders as well as a reduction on the number of attendances to ED. The study suggests that the implementation of a frequent attenders' service is associated with benefits, not only for the individual attendances per patient, but also in an overall reduction of the number patients classed as frequent attenders.Declaration of interestThe authors have no conflict of interest to declare regarding this manuscript.

Development of the Multidimensional Readiness and Enablement Index for Health Technology (READHY) Tool to Measure Individuals' Health Technology Readiness: Initial Testing in a Cancer Rehabilitation Setting

Background

The increasing digitization of health care services with enhanced access to fast internet connections, along with wide use of smartphones, offers the opportunity to get health advice or treatment remotely. For service providers, it is important to consider how consumers can take full advantage of available services and how this can create an enabling environment. However, it is important to consider the digital context and the attributes of current and future users, such as their readiness (ie, knowledge, skills, and attitudes, including trust and motivation).

Objective

The objective of this study was to evaluate how the eHealth Literacy Questionnaire (eHLQ) combined with selected dimensions from the Health Education Impact Questionnaire (heiQ) and the Health Literacy Questionnaire (HLQ) can be used together as an instrument to characterize an individual’s level of health technology readiness and explore how the generated data can be used to create health technology readiness profiles of potential users of health technologies and digital health services.

Methods

We administered the instrument and sociodemographic questions to a population of 305 patients with a recent cancer diagnosis referred to rehabilitation in a setting that plans to introduce various technologies to assist the individuals. We evaluated properties of the Readiness and Enablement Index for Health Technology (READHY) instrument using confirmatory factor analysis, convergent and discriminant validity analysis, and exploratory factor analysis. To identify different health technology readiness profiles in the population, we further analyzed the data using hierarchical and k-means cluster analysis.

Results

The confirmatory factor analysis found a suitable fit for the 13 factors with only 1 cross-loading of 1 item between 2 dimensions. The convergent and discriminant validity analysis revealed many factor correlations, suggesting that, in this population, a more parsimonious model might be achieved. Exploratory factor analysis pointed to 5 to 6 constructs based on aggregates of the existing dimensions. The results were not satisfactory, so we performed an 8-factor confirmatory factor analysis, resulting in a good fit with only 1 item cross-loading between 2 dimensions. Cluster analysis showed that data from the READHY instrument can be clustered to create meaningful health technology readiness profiles of users.

Conclusions

The 13 dimensions from heiQ, HLQ, and eHLQ can be used in combination to describe a user’s health technology readiness level and degree of enablement. Further studies in other populations are needed to understand whether the associations between dimensions are consistent and the number of dimensions can be reduced.

Rationale and methods of an Evaluation of the Effectiveness of the Community Paramedicine at Home (CP@home) program for frequent users of emergency medical services in multiple Ontario regions: a study protocol for a randomized controlled trial

BACKGROUND

Frequent users of emergency medical services for issues that could be more appropriately managed through non-urgent care deplete the limited resources of the health-care system. Community paramedicine is an emerging field that extends the role of paramedics beyond the traditional emergency response. The goal of the current study is to evaluate the impact of a community paramedicine home-visit intervention with frequent users on reducing ambulance calls, hospital visits, and admissions. The study will also provide a cross-sectional description of the characteristics of frequent users of emergency medical services.

METHODS/DESIGN

An open-label, pragmatic, randomized controlled trial with parallel intervention and control groups will be conducted in four paramedic services in Ontario. The sample size has been calculated as 261 per group for a 25% reduction in ambulance calls. Eligible participants will be frequent callers (three or more calls in 6 months), individuals who call for at least one lift assist, or individuals referred to the program by a paramedic. Individuals will be randomly allocated to receive either the Community Paramedicine at Home (CP@home) program intervention or their usual care (control). Intervention participants will receive up to three visits from a community paramedic, who will conduct health risk assessments, provide health promotion and education, provide referrals to local resources, and fax reports back to the family physician. Data will be collected from administrative databases (e.g., paramedic services), a custom CP@home program database, participant surveys, and key informant interviews. An intention-to-treat analysis will be conducted, including descriptive statistics and multi-level modeling to find factors predictive of primary and secondary outcomes. A thematic analysis will be used to analyze the qualitative outcomes. An economic analysis will consider the cost-effectiveness of the program.

DISCUSSION

CP@home has the potential to reduce the health-care system burden significantly by targeting current frequent users of emergency medical services. By targeting this population, CP@home aims to decrease ambulance calls and emergency department visits, reducing health-care costs and improving the quality of life of a vulnerable population. If successful, CP@home will inform the development of community paramedicine policies and the expanding role of paramedics in regions across Canada.

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.

Improving the personalisation of care in a district nursing team: a service improvement project

Service users can benefit in a variety of ways from a personalised approach to care. This service improvement project aimed to improve personalisation for patients being cared for by a community nursing team in the south of England. A plan, study, do, act (PDSA) approach to the project was undertaken with a community nursing team. Both quantitative and qualitative data showed improvement once the focus on personalisation had been improved. Patient and staff satisfaction scores improved and a documentation audit showed the focus on personalisation had increased. Qualitative data suggested that personalisation had also saved staff time, although this measurement was not included in the project. A focus on personalisation can be beneficial for staff and service users.

Dynamic Internet-Mediated Team-Based Case Management of High-Frequency Emergency Department Users

Introduction

We assessed whether a strategy using dynamic, internet-mediated, team-based case management could reduce the number of subsequent emergency department (ED) visits by frequent ED users.

Methods

Patients who attended the ED three or more times within 72 hours in June 2010 were identified. These cases were divided into the pain management or chronic disease group according to their chief complaint. Patients were assessed by expert panels, and initial care plans were developed and posted on an internal website. Thereafter, each emergency physician could follow or adjust the care plans dynamically via the internal website according to the patient's condition and use the website to communicate results. Care plans were revised by the team according to the patient's clinical situation as it changed. Patient ED visits over the subsequent six months were monitored.

Results

Fourteen cases were enrolled in the study, seven in each group. The mean number of visits per patient per month in the pain management and chronic disease groups decreased from 14.9 to 5.79 (p=0.031) and 6.1 to 2.9 (p<0.001) visits per month after the intervention, respectively. The overall mean number of visits per patient per month decreased from 10.5 to 4.36 (p=0.004), a decrease of 6.14 visits (58.27%).

Conclusions

Dynamic internet-mediated team-based case management may help to reduce subsequent visits in patients who frequently visit the ED. (Hong Kong j.emerg.med. 2014;21:161-166)

Patient Navigation for Patients Frequently Visiting the Emergency Department: A Randomized, Controlled Trial

BACKGROUND

Emergency department (ED) superutilizers (patients with five or more visits/year) comprise only 5% of the patients seen yet comprise 25% of total ED visits. Although the reasons for this are multifactorial, the cost to the patient and the community is exceedingly high. The cost is not just monetary; care of these patients is inappropriately fragmented and their presence in the ED may contribute to overcrowding affecting the community's emergency readiness. Previous studies using staff trained to help patients navigate their care options have had conflicting results.

OBJECTIVES

The objective was to determine whether a trained patient navigator (PN) can reduce ED use and costs in superutilizers over a 1-year period.

METHODS

Superutilizers were enrolled in a prospective randomized controlled clinical trial. Patients were randomized into the treatment arm and met with a PN who reviewed their diagnosis and associated care plan and identified proper primary care services and community resources for follow-up. The remaining control group was provided standard care. Both groups were given a follow-up call and survey by the PN within 7 days of their visit who assessed primary care follow-up and patient satisfaction using a 4-point Likert scale. After 12 months, the patients' return ED visits and ED costs were compared to the year prior and primary care compliance and satisfaction were measured using Student's t-tests with Bonferroni correction or Mann-Whitney U-tests.

RESULTS

A total of 282 patients were enrolled (148 in navigation treatment group, 134 controls). Patients were similarly matched in age, race, sex, insurance, and chief complaints. Overall ED visits decreased during the 12-month study period, compared to the 12 months prior to enrollment (2,249 visits prior to 2,050 visits during study period, -8.8%). There was a greater decrease in ED visits from the preenrollment year to postenrollment year in the treatment group (1,148 visits to 996 visits, -13.2%) compared to the control group (1,101 visits to 1,054 visits, -4.3%; p < 0.05). Overall health care costs (ED and hospital) for all 282 patients decreased in the year after compared to the 12 months prior to enrollment ($3.9M to $3.1M) with a greater decrease in the navigation treatment group (-26.6%) compared to the control group (-17.5%). Patient surveys found no difference in patient satisfaction in the pre- and postenrollment periods but there was an increase in primary care physician (PCP) use over the 12-month follow-up period in the treatment group (6.42 visits/patient) compared to the control group (4.07 visits/patient; p < 0.05).

CONCLUSION

Our data showed that the overall number of return ED visits and costs did decrease for both groups, potentially inferring a placebo effect for the use of a PN; however, the decrease in ED visits and costs were greater in the treatment group. One-year follow-up noted an increase in PCP visits in the navigation group. Use of a PN may be cost-effective.

Preparing the prescription: a review of the aim and measurement of social referral programmes

OBJECTIVE

Our aim is to review, and qualitatively evaluate, the aims and measures of social referral programmes. Our first objective is to identify the aims of social referral initiatives. Our second objective is to identify the measures used to evaluate whether the aims of social referral were met.

DESIGN

Literature review.

BACKGROUND

Social referral programmes, also called social prescribing and emergency case referral, link primary and secondary healthcare with community services, often under the guise of decreasing health system costs.

METHOD

Following the PRISMA guidelines, we undertook a literature review to address that aim. We searched in five academic online databases and in one online non-academic search engine, including both academic and grey literature, for articles referring to 'social prescribing' or 'community referral'.

RESULTS

We identified 41 relevant articles and reports. After extracting the aims, measures and type of study, we found that most social referral programmes aimed to address a wide variety of system and individual health problems. This included cost savings, resource reallocation and improved mental, physical and social well-being. Across the 41 studies and reports, there were 154 different kinds of measures or methods of evaluation identified. Of these, the most commonly used individual measure was the Warwick-Edinburgh Mental Well-being Scale, used in nine studies and reports.

CONCLUSIONS

These inconsistencies in aims and measures used pose serious problems when social prescribing and other referral programmes are often advertised as a solution to health services-budgeting constraints, as well as a range of chronic mental and physical health conditions. We recommend researchers and local community organisers alike to critically evaluate for whom, where and why their social referral programmes 'work'.

A case management intervention targeted to reduce healthcare consumption for frequent Emergency Department visitors: results from an adaptive randomized trial

Supplemental Digital Content is available in the text.

Background

A small group of frequent visitors to Emergency Departments accounts for a disproportionally large fraction of healthcare consumption including unplanned hospitalizations and overall healthcare costs. In response, several case and disease management programs aimed at reducing healthcare consumption in this group have been tested; however, results vary widely.

Objectives

To investigate whether a telephone-based, nurse-led case management intervention can reduce healthcare consumption for frequent Emergency Department visitors in a large-scale setup.

Methods

A total of 12 181 frequent Emergency Department users in three counties in Sweden were randomized using Zelen’s design or a traditional randomized design to receive either a nurse-led case management intervention or no intervention, and were followed for healthcare consumption for up to 2 years.

Results

The traditional design showed an overall 12% (95% confidence interval 4–19%) decreased rate of hospitalization, which was mostly driven by effects in the last year. Similar results were achieved in the Zelen studies, with a significant reduction in hospitalization in the last year, but mixed results in the early development of the project.

Conclusion

Our study provides evidence that a carefully designed telephone-based intervention with accurate and systematic patient selection and appropriate staff training in a centralized setup can lead to significant decreases in healthcare consumption and costs. Further, our results also show that the effects are sensitive to the delivery model chosen.

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.

CARES: A Community-wide Collaboration Identifies Super-utilizers and Reduces Their 9-1-1 Call, Emergency Department, and Hospital Visit Rates

BACKGROUND

A subset of individuals who inefficiently and frequently use emergency department (ED) services are called "super-utilizers." Our healthcare system is fragmented and complex, making it difficult for providers to identify super-utilizers and address their wide range of health issues.

OBJECTIVE

The objective of our study was to evaluate a novel community-wide collaboration program called CARES (Community Assistance Referral and Education Services) designed to identify super-utilizers through local partnering organizations. CARES assists patients in developing their personal health and wellness goals, and navigates them away from 9-1-1 calls, emergency room visits, and hospital admissions, and toward more appropriate resources over 90 days.

METHODS

This was a retrospective observational analysis of the CARES program. Data were collected from March 2013 to December 2015. The study population included: enrolled adults with non-compliance of medication or treatment; behavioral health problems; multiple 9-1-1 responses in a short period of time; three or more ED visits within six months; patients with multiple hospital admissions. Adults who were outside of the study period or had missing outcome information were excluded. The primary outcomes of this study were the median rate of 9-1-1 calls/month/person, ED and hospital visits/month/person. Wilcoxon rank-sum tests were used to compare changes between pre- vs. post-enrollment for each subject.

RESULTS

A total of 441 subjects were included in this study. The majority of patients (64%) were female, 64% were white, and the median (IQR) age was 48 (35-62) years old. A total of 51% were on Medicaid and 69% identified behavioral health issues as their barriers to optimal health care. Between pre- and post-enrollment periods, the median (IQR) monthly rate of 9-1-1 calls, ED visits, and hospital admissions significantly decreased by 0.26 (-0.06, 0.90), 0.25 (-0.08, 0.71), and 0.18 (0.04, 0.53) (p < 0.001 for all).

CONCLUSIONS

When health systems in a geographic area share data, they are better able to recognize patterns of overuse, and address them properly. This study demonstrated that a collaborative 90-day intervention identifying super-utilizers reduced the monthly rate of 9-1-1 calls, ED visits, and hospital admissions.

Case Management may Reduce Emergency Department Frequent use in a Universal Health Coverage System: a Randomized Controlled Trial

BACKGROUND

Frequent emergency department (ED) users account for a disproportionately high number of ED visits. Studies on case management (CM) interventions to reduce frequent ED use have shown mixed results, and few studies have been conducted within a universal health coverage system.

OBJECTIVE

To determine whether a CM intervention-compared to standard emergency care-reduces ED attendance.

DESIGN

Randomized controlled trial.

PARTICIPANTS

Two hundred fifty frequent ED users (5 or more visits in the prior 12 months) who visited a public urban ED at the Lausanne University Hospital between May 2012 and July 2013 were allocated to either an intervention (n = 125) or control (n = 125) group, and monitored for 12 months.

INTERVENTIONS

An individualized CM intervention consisting of concrete assistance in obtaining income entitlements, referral to primary or specialty medical care, access to mental health care or substance abuse treatment, and counseling on at-risk behaviors and health care utilization (in addition to standard care) at baseline and 1, 3, and 5 months.

MAIN MEASURES

We used a generalized linear model for count data (negative binomial distribution) to compare the number of ED visits during the 12-month follow-up between CM and usual care, from an intention-to-treat perspective.

KEY RESULTS

At 12 months, there were 2.71 (±0.23) ED visits in the intervention group versus 3.35 (±0.32) visits among controls (ratio = 0.81, 95 % CI = 0.63; 1.02). In the multivariate model, the effect of the CM intervention on the number of ED visits approached statistical significance (b = -0.219, p = 0.075). The presence of poor social determinants of health was a significant predictor of ED use in the multivariate model (b = 0.280, p = 0.048).

CONCLUSIONS

CM may reduce ED use by frequent users through an improved orientation to the health care system. Poor social determinants of health significantly increase use of the ED by frequent users.

Effectiveness of Interventions to Decrease Emergency Department Visits by Adult Frequent Users: A Systematic Review

OBJECTIVES

Frequent emergency department (ED) users are high-risk and high-resource-utilizing patients. This systematic review evaluates effectiveness of interventions targeting adult frequent ED users in reducing visit frequency and improving patient outcomes.

METHODS

An a priori protocol was published in PROSPERO. Two independent reviewers screened, selected, rated quality, and extracted data. Third-party adjudication resolved disagreements. Rate ratios of post- versus pre-intervention ED visits were calculated. Data sources were from a comprehensive search that included seven databases and the gray literature. Eligibility criteria for selecting studies included experimental studies assessing the effect of interventions on frequent users' ED visits and patient-oriented outcomes.

RESULTS

A total of 6,865 citations were identified and 31 studies included. Designs were noncontrolled (n = 21) and controlled (n = 4) before-after studies and randomized controlled trials (n = 6). Frequent user definitions varied considerably and risk of bias was moderate to high. Studies examined general frequent users or those with psychiatric comorbidities, chronic disease, or low socioeconomic status or the elderly. Interventions included case management (n = 18), care plans (n = 8), diversion strategies (n = 3), printout case notes (n = 1), and social work visits (n = 1). Post- versus pre-intervention rate ratios were calculated for 25 studies and indicated a significant visit decrease in 21 (84%) of these studies. The median rate ratio was 0.63 (interquartile range = 0.41 to 0.71), indicating that the general effect of the interventions described was to decrease ED visits post-intervention. Significant visit decreases were found for a majority of studies in subgroup analyses based on 6- or 12-month follow-up, definition thresholds, clinical frequent user subgroups, and intervention types. Studies reporting homelessness found consistent improvements in stable housing. Overall, interstudy heterogeneity was high.

CONCLUSIONS

Interventions targeting frequent ED users appear to decrease ED visits and may improve stable housing. Future research should examine cost-effectiveness and adopt standardized definitions.

Cross-Continuum Tool Is Associated with Reduced Utilization and Cost for Frequent High-Need Users

Introduction

High-need, high-cost (HNHC) patients can over-use acute care services, a pattern of behavior associated with many poor outcomes that disproportionately contributes to increased U.S. healthcare cost. Our objective was to reduce healthcare cost and improve outcomes by optimizing the system of care. We targeted HNHC patients and identified root causes of frequent healthcare utilization. We developed a cross-continuum intervention process and a succinct tool called a Complex Care Map (CCM)© that addresses fragmentation in the system and links providers to a comprehensive individualized analysis of the patient story and causes for frequent access to health services.

Methods

Using a pre-/post-test design in which each subject served as his/her own historical control, this quality improvement project focused on determining if the interdisciplinary intervention called CCM© had an impact on healthcare utilization and costs for HNHC patients. We conducted the analysis between November 2012 and December 2015 at Mercy Health Saint Mary’s, a Midwestern urban hospital with greater than 80,000 annual emergency department (ED) visits. All referred patients with three or more hospital visits (ED or inpatient [IP]) in the 12 months prior to initiation of a CCM© (n=339) were included in the study. Individualized CCMs© were created and made available in the electronic medical record (EMR) to all healthcare providers. We compared utilization, cost, social, and healthcare access variables from the EMR and cost-accounting system for 12 months before and after CCMs© implementation. We used both descriptive and limited inferential statistics.

Results

ED mean visits decreased 43% (p<0.001), inpatient mean admissions decreased 44% (p<0.001), outpatient mean visits decreased 17% (p<0.001), computed tomography mean scans decreased 62% (p<0.001), and OBS/IP length of stay mean days decreased 41% (p<0.001). Gross charges decreased 45% (p<0.001), direct expenses decreased 47% (p<0.001), contribution margin improved by 11% (p=0.002), and operating margin improved by 73% (p<0.001). Patients with housing increased 14% (p<0.001), those with primary care increased 15% (p<0.001), and those with insurance increased 16% (p<0.001).

Conclusion

Individualized CCMs© for a select group of patients are associated with decreased healthcare system overutilization and cost of care.

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.

Designing services for frequent attenders to the emergency department: a characterisation of this population to inform service design

Frequent attendance to the emergency department (ED) is a growing public health concern. Designing services for frequent attenders poses challenges, given the heterogeneous nature of this group. This was a two-part observational study identifying frequent attenders from ED records. The first stage studied trends and developed personas with emphasis on differentiating moderate frequent attenders (attending between 5 and 20 times per year) and extreme frequent attenders (attending more than 20 times). Stage 2 included a case note review of 100 consecutive frequent attenders. Results showed an increase in frequent attendance from 2.59% to 4.12% over 8 years. Moderate frequent attenders accounted for 97%. Of the 100 frequent attenders studied, 45% had medically unexplained symptoms (MUS), associated with younger age (p<0.001) but not with gender (p>0.05). In conclusion, the ED is a useful hub for identifying frequent attenders with MUS, particularly among moderate frequent attenders; service design for this group should consider a 'whole-systems approach' with integration between primary and secondary care, including specialist liaison psychiatry services where appropriate.

Targeting frequent users of emergency departments: Prominent risk factors and policy implications

This study investigates the characteristics of frequent users of accident and emergency departments (AEDs) and recommends alternative medical services for such patients. Prominent demographic and clinical risk factors for individuals accessing seven AEDs located in the metropolitan area of Genoa, Italy are identified and analysed. A truncated count data model is implemented to establish the determinants of access, while a multinomial logistic regression is used to highlight potential differences among different user categories. According to previous studies, empirical findings suggest that despite the relevance of demographic drivers, vulnerability conditions (e.g. abuse of alcohol and drugs, chronic conditions, and psychological distress) are the main reasons behind frequent AED use; the analysis seems to confirm an association between AED frequent use and lower level of urgency. Since frequent and highly frequent users are found responsible for disproportionate resource absorption with respect to total amount of AED costs (they represent roughly 10% of the total number of patients, but contribute to more than 19% of the total annual AED cost), policies aiming to reduce frequent use of AEDs could bring significant savings in economic resources. Thus, efficient actions could be oriented toward extending primary care services outside AED and toward instituting local aid services specifically addressed to people under the influence of substances or in conditions of mental distress.

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.

Reducing frequent visits to the emergency department: a systematic review of interventions

Objective

The objective of this study was to establish the effectiveness of interventions to reduce frequent emergency department (ED) use among a general adult high ED-use population.

Methods

Systematic review of the literature from 1950-January 2015. Studies were included if they: had a control group (controlled trials or comparative cohort studies), were set in an ED or acute care facility, and examined the impact of an intervention to reduce frequent ED use in a general adult population. Studies reporting non-original data or focused on a specific patient population were excluded. Study design, patient population, intervention, the frequency of ED visits, and costs of frequent ED use and/or interventions were extracted and narratively synthesized.

Results

Among 17 included articles, three intervention categories were identified: case management (n = 12), individualized care plans (n = 3), and information sharing (n = 2). Ten studies examining case management reported reductions in mean (-0.66 to -37) or median (-0.1 to -20) number of ED visits after 12-months; one study reported an increase in mean ED visits (+2.79); and one reported no change. Of these, 6 studies also reported reduced hospital costs. Only 1 study evaluating individualized care plans examined ED utilization and found no change in median ED visits post-intervention. Costs following individualized care plans were also only evaluated in 1 study, which reported savings in hospital costs of $742/patient. Evidence was mixed regarding information sharing: 1 study reported no change in mean ED visits and did not examine costs; whereas the other reported a decrease in mean ED visits (-16.9) and ED cost savings of $15,513/patient.

Conclusions

The impact of all three frequent-user interventions was modest. Case management had the most rigorous evidence base, yielded moderate cost savings, but with variable reductions in ED use. Future studies evaluating non-traditional interventions, tailoring to patient subgroups or socio-cultural contexts, are warranted.

Demand for hospital emergency departments: a conceptual understanding

BACKGROUND

Emergency departments (EDs) are critical to the management of acute illness and injury, and the provision of health system access. However, EDs have become increasingly congested due to increased demand, increased complexity of care and blocked access to ongoing care (access block). Congestion has clinical and organisational implications. This paper aims to describe the factors that appear to influence demand for ED services, and their interrelationships as the basis for further research into the role of private hospital EDs.

DATA SOURCES

Multiple databases (PubMed, ProQuest, Academic Search Elite and Science Direct) and relevant journals were searched using terms related to EDs and emergency health needs. Literature pertaining to emergency department utilisation worldwide was identified, and articles selected for further examination on the basis of their relevance and significance to ED demand.

RESULTS

Factors influencing ED demand can be categorized into those describing the health needs of the patients, those predisposing a patient to seeking help, and those relating to policy factors such as provision of services and insurance status. This paper describes the factors influencing ED presentations, and proposes a novel conceptual map of their interrelationship.

CONCLUSION

This review has explored the factors contributing to the growing demand for ED care, the influence these factors have on ED demand, and their interrelationships depicted in the conceptual model.

Characteristics and outcome of patients brought to an emergency department by police under the provisions (Section 10) of the Mental Health Act in Victoria, Australia

OBJECTIVE

The aim of this study is to describe the characteristics and outcome of patients brought to an emergency department by police under Section 10 of Mental Health Act (Victoria, Australia).

METHODS

Retrospective medical record review. Patients referred under Section 10 provisions treated in calendar year 2009 were identified from ED database. Data collected included demographics, incident details, patient management, final diagnosis and disposition. Primary outcomes of interest were ED diagnosis and disposition. Secondary outcomes were length of stay in ED and use of restraint or sedation.

RESULTS

One hundred and ninety seven presentations by 164 patients were identified. Patients were predominantly male (58%) with median age of 35 years (IQR 22-44, range 16-69). The most common presenting complaint (65%) was threat of self harm. No sedation or restraint was used in 61%. Sixty seven percent were deemed safe for discharge home while 26% were admitted to a psychiatric ward (equally divided between voluntary and involuntary admission). The predominant discharge diagnosis was self harm ideation or intent (35%). Median ED length of stay was 156 min (inter-quartile range 79-416).

CONCLUSION

Most patients brought to ED by police under Section 10 provisions were for threat of self harm and did not require sedation or restraint. The majority are discharged home. Further work exploring less restrictive or traumatic processes to facilitate psychiatric assessment of this group of patients is warranted.

Case management for frequent users of the emergency department: study protocol of a randomised controlled trial

Background

We devised a randomised controlled trial to evaluate the effectiveness and efficiency of an intervention based on case management care for frequent emergency department users. The aim of the intervention is to reduce such patients’ emergency department use, to improve their quality of life, and to reduce costs consequent on frequent use. The intervention consists of a combination of comprehensive case management care and standard emergency care. It uses a clinical case management model that is patient-identified, patient-directed, and developed to provide high intensity services. It provides a continuum of hospital- and community-based patient services, which include clinical assessment, outreach referral, and coordination and communication with other service providers.

Methods/Design

We aim to recruit, during the first year of the study, 250 patients who visit the emergency department of the University Hospital of Lausanne, Switzerland. Eligible patients will have visited the emergency department 5 or more times during the previous 12 months. Randomisation of the participants to the intervention or control groups will be computer generated and concealed. The statistician and each patient will be blinded to the patient’s allocation. Participants in the intervention group (N = 125), additionally to standard emergency care, will receive case management from a team, 1 (ambulatory care) to 3 (hospitalization) times during their stay and after 1, 3, and 5 months, at their residence, in the hospital or in the ambulatory care setting. In between the consultations provided, the patients will have the opportunity to contact, at any moment, the case management team. Participants in the control group (N = 125) will receive standard emergency care only. Data will be collected at baseline and 2, 5.5, 9, and 12 months later, including: number of emergency department visits, quality of life (EuroQOL and WHOQOL), health services use, and relevant costs. Data on feelings of discrimination and patient’s satisfaction will also be collected at the baseline and 12 months later.

Discussion

Our study will help to clarify knowledge gaps regarding the positive outcomes (emergency department visits, quality of life, efficiency, and cost-utility) of an intervention based on case management care.

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.

Salford alcohol assertive outreach team: a new model for reducing alcohol-related admissions

OBJECTIVE

Alcohol-related admissions are increasing. A significant number of these admissions are attributable to a small number of complex patients with other comorbidities who do not engage well with mainstream services. Assertive outreach teams have been used in the field of psychiatry to engage patients who are poorly compliant. This study examines whether an alcohol assertive outreach team (AAOT) can engage with this group and reduce hospital admissions.

DESIGN

The AAOT is a multidisciplinary team with medical, psychiatric, substance misuse, psychology, nursing and social work specialists. The team worked with patients with the highest number of alcohol-related admissions and case managed in a community setting for 6 months. The admission and emergency department attendances of the cohort were compared for the 3-month period before and after the intervention. Christo inventory for substance misuse services (CISS) scores were determined pre and post the intervention period.

RESULTS

54 patients were case managed. The total number of admissions in 3 months fell from 151 prior to the intervention period to 50 following the intervention. Emergency department attendances also fell from 360 in 3 months to 146 following the intervention period. CISS scores fell from 11 preintervention to eight postintervention.

CONCLUSIONS

An AAOT model appears to reduce hospital admissions and emergency department attendances in a complex group of patients that display high alcohol-related admissions.

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.

Effects of an emergency medical services-based resource access program on frequent users of health services

BACKGROUND

A small group of adults disproportionately and ineffectively use acute services including emergency medical services (EMS) and emergency departments (EDs). The resulting episodic, uncoordinated care is of lower quality and higher cost and simultaneously consumes valuable public safety and acute care resources.

OBJECTIVE

To address this issue, we measured the impact of a pilot, EMS-based case management and referral intervention termed the San Diego Resource Access Program (RAP) to reduce EMS, ED, and inpatient (IP) visits.

METHODS

This was a historical cohort study of RAP records and billing data of EMS and one urban hospital for 51 individuals sequentially enrolled in the program. The study sample consisted of adults with ≥ 10 EMS transports within 12 months and others reported by prehospital personnel with significant recent increases in transports. Data were collected over a 31-month time period from December 2006 to June 2009. Data were collected for equal pre- and postenrollment time periods based on date of initial RAP contact, and comparisons were made using the Wilcoxon signed-rank test. Overall use for subjects is reported.

RESULTS

The majority of subjects were male (64.7%), homeless (58.8%), and 40 to 59 years of age (72.5%). Between the pre and post periods, EMS encounters declined 37.6% from 736 to 459 (p = 0.001), resulting in a 32.1% decrease in EMS charges from $689,743 to $468,394 (p = 0.004). The EMS task time and mileage decreased by 39.8% and 47.5%, respectively, accounting for 262 (p = 0.008) hours and 1,940 (p = 0.006) miles. The number of ED encounters at the one participating hospital declined 28.1% from 199 to 143, which correlated with a 12.7% decrease in charges from $413,410 to $360,779. The number of IP admissions declined by 9.1% from 33 to 30, corresponding to a 5.9% decrease in IP charges from $687,306 to $646,881. Hospital length of stay declined 27.9%, from 122 to 88 days. Across all services, total charges declined by $314,406.

CONCLUSIONS

This pilot study demonstrated that an EMS-based case management and referral program was an effective means of decreasing EMS transports by frequent users, but had only a limited impact on use of hospital services.

Characteristics of frequent emergency department presenters to an Australian emergency medicine network

BACKGROUND

To describe the characteristics of emergency department (ED) patients defined as frequent presenters (FP) presenting to an Australian emergency department network and compare these with a cohort of non-frequent presenters (NFP).

METHOD

A retrospective chart review utilising an electronic emergency medicine patient medical record database was performed on patients presenting to Southern Health EDs from March 2009 to March 2010. Non-frequent presenters were defined as patients presenting less than 5 times and frequent presenters as presenting 8 or more times in the study period. Characteristics of both groups were described and compared.

RESULTS

During the 12-month study period there were 540 FP patients with 4549 admissions and 73,089 NFP patients with 100,943 admissions. FP patients were slightly older with a significant increase in frequency of patients between the ages of 70 to 79 years and they were more likely to be divorced or separated than NFP patients. Frequent presenters to the emergency department were more likely to utilise the ambulance service to arrive at the hospital, or in the custody of police than NFP patients. FPs were more likely to be admitted to hospital, more likely to have an admission to a mental health bed than NFP patients and more likely to self-discharge from the emergency department while waiting for care.

CONCLUSIONS

There are major implications for the utilisation of limited ED resources by frequent presenters. By further understanding the characteristics of FP we may be able to address the specific health care needs of this population in more efficient and cost effective ways. Further research analysing the effectiveness of targeted multidisciplinary interventions aiming to reduce the frequency of ED attendances may be warranted.

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.
