The effects of clinical case management on hospital service use among ED frequent users

Examining the experiences of vulnerably housed patients visiting Kingston, Ontario's emergency departments: a qualitative analysis

INTRODUCTION

Vulnerably housed individuals access emergency departments (EDs) more frequently than the general population. Despite Canada's universal public health care system, vulnerably housed persons face structural barriers to care and experience discrimination from healthcare providers. This study examines how vulnerably housed persons perceive their experience of care in the ED and Urgent Care Center (UCC) in Kingston, Ontario and aims to develop strategies for improving care for this group.

METHODS

As part of a larger mixed-methods study, narratives were collected from participants attending the ED/UCC as well as community-based partner organizations, asking them to describe an experience of a recent ED visit (< 24 months). Participants could identify as members of up to three equity-deserving groups (EDGs) (for example homeless, part of an ethnic minority, having a disability, experiencing mental health issues). Coding and thematic analysis were completed for the experiences of participants who identified as being vulnerably housed (n = 171). Results were presented back to individuals with lived experience and service providers working with clients with unstable housing.

RESULTS

Participants reported judgement related to a past or presumed history of mental health or substance use and based on physical appearance. They also often felt unheard and that they were treated as less than human by healthcare providers. Lack of effective communication about the ED process, wait times, diagnosis, and treatment led to negative care experiences. Participants reported positive experiences when their autonomy in care-decision making was respected. Furthermore, having a patient-centered approach to care and addressing specific patient needs, identities and priorities led to positive care experiences.

CONCLUSIONS

The ED care experiences of vulnerably housed persons may be improved through healthcare provider training related to trauma-informed and patient-centered care and communication strategies in the ED. Another potential strategy to improve care is to have advocates accompany vulnerably housed persons to the ED. Finally, improving access to primary care may lead to reduced ED visits and better longitudinal care for vulnerably housed persons.

Racial Health Equity and Social Needs Interventions: A Review of a Scoping Review

IMPORTANCE

Social needs interventions aim to improve health outcomes and mitigate inequities by addressing health-related social needs, such as lack of transportation or food insecurity. However, it is not clear whether these studies are reducing racial or ethnic inequities.

OBJECTIVE

To understand how studies of interventions addressing social needs among multiracial or multiethnic populations conceptualize and analyze differential intervention outcomes by race or ethnicity.

EVIDENCE REVIEW

Sources included a scoping review of systematic searches of PubMed and the Cochrane Library from January 1, 1995, through November 29, 2021, expert suggestions, and hand searches of key citations. Eligible studies evaluated interventions addressing social needs; reported behavioral, health, or utilization outcomes or harms; and were conducted in multiracial or multiethnic populations. Two reviewers independently assessed titles, abstracts, and full text for inclusion. The team developed a framework to assess whether the study was "conceptually thoughtful" for understanding root causes of racial health inequities (ie, noted that race or ethnicity are markers of exposure to racism) and whether analyses were "analytically informative" for advancing racial health equity research (ie, examined differential intervention impacts by race or ethnicity).

FINDINGS

Of 152 studies conducted in multiracial or multiethnic populations, 44 studies included race or ethnicity in their analyses; of these, only 4 (9%) were conceptually thoughtful. Twenty-one studies (14%) were analytically informative. Seven of 21 analytically informative studies reported differences in outcomes by race or ethnicity, whereas 14 found no differences. Among the 7 that found differential outcomes, 4 found the interventions were associated with improved outcomes for minoritized racial or ethnic populations or reduced inequities between minoritized and White populations. No studies were powered to detect differences.

CONCLUSIONS AND RELEVANCE

In this review of a scoping review, studies of social needs interventions in multiracial or multiethnic populations were rarely conceptually thoughtful for understanding root causes of racial health inequities and infrequently conducted informative analyses on intervention effectiveness by race or ethnicity. Future work should use a theoretically sound conceptualization of how race (as a proxy for racism) affects social drivers of health and use this understanding to ensure social needs interventions benefit minoritized racial and ethnic groups facing social and structural barriers to health.

Hospital-based preventative interventions for people experiencing homelessness in high-income countries: A systematic review

BACKGROUND

People experiencing homelessness have significant unmet needs and high rates of unplanned care. We aimed to describe preventative interventions, defined in their broadest sense, for people experiencing homelessness in a hospital context. Secondary aims included mapping outcomes and assessing intervention effectiveness.

METHODS

We searched online databases (MEDLINE, Embase, PsycINFO, HMIC, CINAHL, Web of Science, Cochrane Library) from 1999-2019 and conducted backward and forward citation searches to 31 December 2020 (PROSPERO CRD42019154036). We included quantitative studies in emergency and inpatient settings measuring health or social outcomes for adults experiencing homelessness in high income countries. We assessed rigour using the "Quality Assessment Tool for Quantitative Studies" and summarised findings using descriptive quantitative methods, a binomial test, a Harvest Plot, and narrative synthesis. We used PRISMA and SWiM reporting guidelines.

FINDINGS

Twenty-eight studies identified eight intervention types: care coordination (n=18); advocacy, support, and outreach (n=13); social welfare assistance (n=13); discharge planning (n=12); homelessness identification (n=6); psychological therapy and treatment (n=6); infectious disease prevention (n=5); and screening, treatment, and referrals (n=5). The evidence strength was weak (n=16) to moderate (n=10), with two high quality randomised controlled trials. We identified six outcome categories with potential benefits observed for psychosocial outcomes, including housing (11/13 studies, 95%CI=54.6-98.1%, p=0.023), healthcare use (14/17, 56.6-96.2%, p=0.013), and healthcare costs (8/8, 63.1-100%, p=0.008). Benefits were less likely for health outcomes (4/5, 28.3-99.5%, p=0.375), integration with onward care (2/4, 6.8-93.2%, p=1.000), and feasibility/acceptability (5/6, 35.9-99.6%, p=0.219), but confidence intervals were very wide. We observed no harms. Most studies showing potential benefits were multi-component interventions.

INTERPRETATION

Hospital-based preventative interventions for people experiencing homelessness are potentially beneficial, but more rigorous research is needed. In the context of high needs and extreme inequities, policymakers and healthcare providers may consider implementing multi-component preventative interventions.

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.

Screening and Interventions for Social Risk Factors: Technical Brief to Support the US Preventive Services Task Force

IMPORTANCE

Evidence-based guidance is limited on how clinicians should screen for social risk factors and which interventions related to these risk factors improve health outcomes.

OBJECTIVE

To describe research on screening and interventions for social risk factors to inform US Preventive Services Task Force considerations of the implications for its portfolio of recommendations.

DATA SOURCES

Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Ovid MEDLINE, Sociological Abstracts, and Social Services Abstracts (through 2018); Social Interventions Research and Evaluation Network evidence library (January 2019 through May 2021); surveillance through May 21, 2021; interviews with 17 key informants.

STUDY SELECTION

Individual-level and health care system-level interventions with a link to the health care system that addressed at least 1 of 7 social risk domains: housing instability, food insecurity, transportation difficulties, utility needs, interpersonal safety, education, and financial strain.

DATA EXTRACTION AND SYNTHESIS

One investigator abstracted data from studies and a second investigator evaluated data abstractions for completeness and accuracy; key informant interviews were recorded, transcribed, summarized, and integrated with evidence from the literature; narrative synthesis with supporting tables and figures.

MAIN OUTCOMES AND MEASURES

Validity of multidomain social risk screening tools; all outcomes reported for social risk-related interventions; challenges or unintended consequences of screening and interventions.

RESULTS

Many multidomain social risk screening tools have been developed, but they vary widely in their assessment of social risk and few have been validated. This technical brief identified 106 social risk intervention studies (N = 5 978 596). Of the interventions studied, 73 (69%; n = 127 598) addressed multiple social risk domains. The most frequently addressed domains were food insecurity (67/106 studies [63%], n = 141 797), financial strain (52/106 studies [49%], n = 111 962), and housing instability (63/106 studies [59%], n = 5 881 222). Food insecurity, housing instability, and transportation difficulties were identified by key informants as the most important social risk factors to identify in health care. Thirty-eight studies (36%, n = 5 850 669) used an observational design with no comparator, and 19 studies (18%, n = 15 205) were randomized clinical trials. Health care utilization measures were the most commonly reported outcomes in the 68 studies with a comparator (38 studies [56%], n = 111 102). The literature and key informants described many perceived or potential challenges to implementation of social risk screening and interventions in health care.

CONCLUSIONS AND RELEVANCE

Many interventions to address food insecurity, financial strain, and housing instability have been studied, but more randomized clinical trials that report health outcomes from social risk screening and intervention are needed to guide widespread implementation in health care.

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.

Predictive Model-Driven Hotspotting to Decrease Emergency Department Visits: a Randomized Controlled Trial

BACKGROUND

Emergency department (ED) visits contribute substantially to health care expenditures. Case management has been proposed as a strategy to address the medical and social needs of complex patients. However, strong research designs to evaluate the effectiveness of such interventions are limited.

OBJECTIVES

To evaluate whether a community-based case management program was associated with reduced ED utilization among complex patients.

DESIGN

Patients whose risk exceeded a threshold were randomly assigned to a group offered case management or to the control group. Assignment occurred at five intervals between November 2017 and January 2019. Program effectiveness for all assigned patients was assessed using an intention-to-treat effect. Program effectiveness among those who received treatment was assessed using a local average treatment effect, estimated using instrumental variables. Both estimators were adjusted for baseline characteristics using linear models.

PARTICIPANTS

Adults over age 18 with at least one health care encounter with Michigan Medicine or St. Joseph Mercy Health System between June 2, 2016, and November 27, 2018.

INTERVENTIONS

Intervention arm participants (n = 486) were offered coordinated case management across medical, mental health, and social service organizations. Control arm participants (n = 409) received usual care.

MAIN MEASURES

The primary outcome was the number of ED visits in the 6 months following randomization into the study. Secondary outcomes were 6-month counts of inpatient and outpatient visits.

KEY RESULTS

Of the 486 patients assigned to the intervention, 131 (27%) consented to receive case management. The intention-to-treat effect on ED visits was + 0.14 (95% CI: - 0.27 to + 0.55). The local average treatment effect among those who consented and received case management was + 0.53 (95% CI: - 1.00 to + 2.05). Intention-to-treat and local average treatment effects were not significant for secondary outcomes.

CONCLUSIONS

The community case management intervention targeting ED visits was not associated with reduced utilization. Future case management interventions may benefit from additional patient engagement strategies and longer evaluation time periods.

Identification of social determinants of health using multi-label classification of electronic health record clinical notes

OBJECTIVES

Social determinants of health (SDH), key contributors to health, are rarely systematically measured and collected in the electronic health record (EHR). We investigate how to leverage clinical notes using novel applications of multi-label learning (MLL) to classify SDH in mental health and substance use disorder patients who frequent the emergency department.

METHODS AND MATERIALS

We labeled a gold-standard corpus of EHR clinical note sentences (N = 4063) with 6 identified SDH-related domains recommended by the Institute of Medicine for inclusion in the EHR. We then trained 5 classification models: linear-Support Vector Machine, K-Nearest Neighbors, Random Forest, XGBoost, and bidirectional Long Short-Term Memory (BI-LSTM). We adopted 5 common evaluation measures: accuracy, average precision-recall (AP), area under the curve receiver operating characteristic (AUC-ROC), Hamming loss, and log loss to compare the performance of different methods for MLL classification using the F1 score as the primary evaluation metric.

RESULTS

Our results suggested that, overall, BI-LSTM outperformed the other classification models in terms of AUC-ROC (93.9), AP (0.76), and Hamming loss (0.12). The AUC-ROC values of MLL models of SDH related domains varied between (0.59-1.0). We found that 44.6% of our study population (N = 1119) had at least one positive documentation of SDH.

DISCUSSION AND CONCLUSION

The proposed approach of training an MLL model on an SDH rich data source can produce a high performing classifier using only unstructured clinical notes. We also provide evidence that model performance is associated with lexical diversity by health professionals and the auto-generation of clinical note sentences to document SDH.

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.

A comprehensive review of prioritised interventions to improve the health and wellbeing of persons with lived experience of homelessness

Background

Homelessness has emerged as a public health priority, with growing numbers of vulnerable populations despite advances in social welfare. In February 2020, the United Nations passed a historic resolution, identifying the need to adopt social-protection systems and ensure access to safe and affordable housing for all. The establishment of housing stability is a critical outcome that intersects with other social inequities. Prior research has shown that in comparison to the general population, people experiencing homelessness have higher rates of infectious diseases, chronic illnesses, and mental-health disorders, along with disproportionately poorer outcomes. Hence, there is an urgent need to identify effective interventions to improve the lives of people living with homelessness.

Objectives

The objective of this systematic review is to identify, appraise, and synthesise the best available evidence on the benefits and cost-effectiveness of interventions to improve the health and social outcomes of people experiencing homelessness.

Search Methods

In consultation with an information scientist, we searched nine bibliographic databases, including Medline, EMBASE, and Cochrane CENTRAL, from database inception to February 10, 2020 using keywords and MeSH terms. We conducted a focused grey literature search and consulted experts for additional studies.

Selection Criteria

Teams of two reviewers independently screened studies against our inclusion criteria. We included randomised control trials (RCTs) and quasi-experimental studies conducted among populations experiencing homelessness in high-income countries. Eligible interventions included permanent supportive housing (PSH), income assistance, standard case management (SCM), peer support, mental health interventions such as assertive community treatment (ACT), intensive case management (ICM), critical time intervention (CTI) and injectable antipsychotics, and substance-use interventions, including supervised consumption facilities (SCFs), managed alcohol programmes and opioid agonist therapy. Outcomes of interest were housing stability, mental health, quality of life, substance use, hospitalisations, employment and income.

Data Collection and Analysis

Teams of two reviewers extracted data in duplicate and independently. We assessed risk of bias using the Cochrane Risk of Bias tool. We performed our statistical analyses using RevMan 5.3. For dichotomous data, we used odds ratios and risk ratios with 95% confidence intervals. For continuous data, we used the mean difference (MD) with a 95% CI if the outcomes were measured in the same way between trials. We used the standardised mean difference with a 95% CI to combine trials that measured the same outcome but used different methods of measurement. Whenever possible, we pooled effect estimates using a random-effects model.

Main Results

The search resulted in 15,889 citations. We included 86 studies (128 citations) that examined the effectiveness and/or cost-effectiveness of interventions for people with lived experience of homelessness. Studies were conducted in the United States (73), Canada (8), United Kingdom (2), the Netherlands (2) and Australia (1). The studies were of low to moderate certainty, with several concerns regarding the risk of bias. PSH was found to have significant benefits on housing stability as compared to usual care. These benefits impacted both high- and moderate-needs populations with significant cimorbid mental illness and substance-use disorders. PSH may also reduce emergency department visits and days spent hospitalised. Most studies found no significant benefit of PSH on mental-health or substance-use outcomes. The effect on quality of life was also mixed and unclear. In one study, PSH resulted in lower odds of obtaining employment. The effect on income showed no significant differences. Income assistance appeared to have some benefits in improving housing stability, particularly in the form of rental subsidies. Although short-term improvement in depression and perceived stress levels were reported, no evidence of the long-term effect on mental health measures was found. No consistent impact on the outcomes of quality of life, substance use, hospitalisations, employment status, or earned income could be detected when compared with usual services. SCM interventions may have a small beneficial effect on housing stability, though results were mixed. Results for peer support interventions were also mixed, though no benefit was noted in housing stability specifically. Mental health interventions (ICM, ACT, CTI) appeared to reduce the number of days homeless and had varied effects on psychiatric symptoms, quality of life, and substance use over time. Cost analyses of PSH interventions reported mixed results. Seven studies showed that PSH interventions were associated with increased cost to payers and that the cost of the interventions were only partially offset by savings in medical- and social-services costs. Six studies revealed that PSH interventions saved the payers money. Two studies focused on the cost-effectiveness of income-assistance interventions. For each additional day housed, clients who received income assistance incurred additional costs of US$45 (95% CI, -$19, -$108) from the societal perspective. In addition, the benefits gained from temporary financial assistance were found to outweigh the costs, with a net savings of US$20,548. The economic implications of case management interventions (SCM, ICM, ACT, CTI) was highly uncertain. SCM clients were found to incur higher costs than those receiving the usual care. For ICM, all included studies suggested that the intervention may be cost-offset or cost-effective. Regarding ACT, included studies consistently revealed that ACT saved payers money and improved health outcomes than usual care. Despite having comparable costs (US$52,574 vs. US$51,749), CTI led to greater nonhomeless nights (508 vs. 450 nights) compared to usual services.

Authors' Conclusions

PSH interventions improved housing stability for people living with homelessness. High-intensity case management and income-assistance interventions may also benefit housing stability. The majority of included interventions inconsistently detected benefits for mental health, quality of life, substance use, employment and income. These results have important implications for public health, social policy, and community programme implementation. The COVID-19 pandemic has highlighted the urgent need to tackle systemic inequality and address social determinants of health. Our review provides timely evidence on PSH, income assistance, and mental health interventions as a means of improving housing stability. PSH has major cost and policy implications and this approach could play a key role in ending homelessness. Evidence-based reviews like this one can guide practice and outcome research and contribute to advancing international networks committed to solving homelessness.

Case Management and Telehealth: A Scoping Review

Background: Case management (CM) is an intervention adapted to the needs of patients with chronic conditions or complex needs. Factors associated with effectiveness of CM, such as high intervention intensity, can represent challenges to its implementation. Telehealth has the potential to help overcome these challenges, but little work has been done to synthesize available evidence on telehealth CM. The purpose of this scoping review was thus to fill this gap and document which telehealth modalities have been used, summarize perspectives of key users, and discuss evidence on effectiveness of telehealth-delivered CM. Methods: A search in MEDLINE, Scopus, and CINAHL for articles published between January 2005 and January 2021 was done. Studies in which telehealth was used for patient-case manager interaction and conducted in a population with complex health needs and/or chronic conditions were included. Articles selected for full-text review were independently screened by two reviewers. Data extraction was conducted once and validated by a second reviewer. Results: Of 3,108 articles, 22 were retained for data extraction. A narrative synthesis was conducted. Most studies evaluated CM interventions delivered over telephone, yet, literature suggests that face-to-face contact is essential to CM success. Results also indicate that telehealth CM is acceptable and effective, associated with better utilization of health services and favorable clinical outcomes. Conclusions: Lack of research evaluating telehealth CM delivered using modalities other than telephone. Further research should evaluate CM interventions that integrate platforms enabling visual information exchange.

Social media language of healthcare super-utilizers

An understanding of healthcare super-utilizers' online behaviors could better identify experiences to inform interventions. In this retrospective case-control study, we analyzed patients' social media posts to better understand their day-to-day behaviors and emotions expressed online. Patients included those receiving care in an urban academic emergency department who consented to share access to their historical Facebook posts and electronic health records. Super-utilizers were defined as patients with more than six visits to the Emergency Department (ED) in a year. We compared posts by super-utilizers with a matched group using propensity scoring based on age, gender and Charlson comorbidity index. Super-utilizers were more likely to post about confusion and negativity (D = .65, 95% CI-[.38, .95]), self-reflection (D = .63 [.35, .91]), avoidance (D = .62 [.34, .90]), swearing (D = .52 [.24, .79]), sleep (D = .60 [.32, .88]), seeking help and attention (D = .61 [.33, .89]), psychosomatic symptoms, (D = .49 [.22, .77]), self-agency (D = .56 [.29, .85]), anger (D = .51, [.24, .79]), stress (D = .46, [.19, .73]), and lonely expressions (D = .44, [.17, .71]). Insights from this study can potentially supplement offline community care services with online social support interventions considering the high engagement of super-utilizers on social media.

Emergency department interventions for homelessness: a systematic review

BACKGROUND

The social determinants of health are economic and social conditions that contribute to health. Access to housing is a major social determinant of health and homeless patients often rely on emergency departments (EDs) for their healthcare. These patients are frequently discharged back to the street which further perpetuates the cycle of homelessness and negatively affects their health. Previous work has described the financial and systems implications of ED-housed interventions for homeless patients; this review summarizes ED-based interventions that seek to improve the social determinants of health of homeless patients.

METHODS

We conducted a search of multiple databases and gray literature for studies investigating interventions for homelessness that were initiated in the ED. Studies had to use a control group or use a pre/post-intervention design and measure outcomes that demonstrate an effect on health or the social determinants of health.

RESULTS

Thirteen studies were identified that met the inclusion criteria. Two studies were housing first interventions and were effective in providing housing and improving health. Seven studies used variations of case management and were able to address many of the social needs of people who are homeless.

CONCLUSION

This review demonstrated that ED interventions can be effective in improving the social determinants of health of homeless individuals and can be the place to initiate housing interventions. ED providers must advocate for the resources necessary to properly address the social needs of this marginalized population. Equipped with the proper resources, EDs can be one place where the cycle of homelessness is broken.

Health care providers' perception of the frequent emergency department user issue and of targeted case management interventions: a cross-sectional national survey in Switzerland

Background

Frequent users of emergency departments (FUEDs) (≥5 ED visits/year) represent a vulnerable population with complex needs accounting for a significant number of emergency department (ED) consultations, thus contributing to EDs overcrowding. Research exploring ED staff perceptions of FUEDs is scarce.

Objectives

The current study aimed to evaluate in ED staff a) the extent to which FUEDs are perceived as an issue; b) their perceived levels of knowledge and understanding of FUEDs; c) levels of perceived usefulness of case management (CM) and interest in implementing this intervention in their ED service.

Methods

Head physicians of the EDs at all public hospitals in Switzerland (of various level of specialization) were sent a 19-item web-based survey, pilot tested prior to its dissemination. The head physicians were asked to forward the survey to ED staff members from different health professional backgrounds.

Results

The hospital response rate was 81% (85/106). The exploitable hospital response rate was 71% (75/106 hospitals) including 208 responding health professionals. Issues and difficulties around FUEDs were perceived as important by 64% of respondents. The perceived frequency of being confronted with FUEDs was higher among nurses in more specialized EDs. In total, 64% of respondents felt poorly informed about FUEDs, nurses feeling less informed than physicians. The understanding of FUEDs was lower in the French-Italian-speaking parts (FISP) of Switzerland than in the German-speaking part. Eighty-one percent of respondents had no precise knowledge of FUED-related interventions. The perceived usefulness of CM interventions after receiving explanations about it was high (92%). However, the overall level of interest for CM implementation was 59%. The interest in CM by physicians was low across all regions and ED categories. Nurses, on the other hand, showed more interest, especially those in EDs of high specialization.

Conclusions

The majority of ED staff reported being confronted with FUEDs on a regular basis. Staff perceived FUEDs as a vulnerable population, yet, they felt poorly informed about how to manage the issue. The majority of ED staff thought a CM intervention would be useful for FUEDs, however there appears to be a gap in their desire or willingness to implement such interventions.

Evaluating the effectiveness of concurrent opioid agonist treatment and physician-based mental health services for patients with mental disorders in Ontario, Canada

Objective

The objective of this study was to evaluate the relationship between concurrent physician-based mental health services, all-cause mortality, and acute health service use for individuals enrolled in Opioid Agonist Treatment in Ontario, Canada.

Methods

A cohort study of patients enrolled in opioid agonist treatment in Ontario was conducted between January 1, 2011, and December 31, 2015, in Ontario with an inverse probability of treatment weights using the propensity score to estimate the effect of physician-based mental health services. Treatment groups were created based on opioid agonist treatment patients’ utilization of physician-based mental health services. Propensity score weighted odds ratios were calculated to assess the relationship between the treatment groups and the outcomes of interest. The outcomes included all-cause mortality using data from the Registered Persons Database, Emergency Department visits from the National Ambulatory Care Database, and hospitalizations using data from the Discharge Abstract Database. Encrypted patient identifiers were used to link across databases.

Results

A total of 48,679 individuals in OAT with mental disorders. Opioid agonist treatment alone was associated with reduced odds of all-cause mortality (odds ratio (OR) 0.4, 95% confidence interval (CI) 0.3–0.4). Patients who received mental health services from a psychiatrist and primary care physician while engaged in OAT, the estimated rate of ED visits per year was higher (OR = 1.3, 95% CI 1.2–1.4) and the rate of hospitalizations (OR = 0.5, 95% CI 0.4–0.6) than in the control group.

Conclusion

Our findings support the view that opioid agonist treatment and concurrent mental health services can improve clinical outcomes for complex patients, and is associated with enhanced use of acute care services.

What causes high costs for rural tuberculosis inpatients? Evidence from five counties in China

Background

Tuberculosis (TB) still causes high economic burden on patients in China, especially for rural patients. Our study aims to explore the risk factors associated with the high costs for TB inpatients in rural China from the aspects of inpatients’ socio-demographic and institutional attributes.

Methods

Generalized linear models were utilized to investigate the factors associated with TB inpatients’ total costs and out-of-pocket (OOP) expenditures. Quantile regression (QR) models were applied to explore the effect of each factor across the different costs range and identify the risk factors of high costs.

Results

TB inpatients with long length of stay and who receive hospitalization services cross provincially, in tertiary and specialized hospitals were likely to face high total costs and OOP expenditures. QR models showed that high total costs occurred in Dingyuan and Funan Counties, but they were not accompanied by high OOP expenditures.

Conclusions

Early diagnosis, standard treatment and control of drug-resistant TB are still awaiting for more efforts from the government. TB inpatients should obtain medical services from appropriate hospitals. The diagnosis and treatment process of TB should be standardized across all designated medical institutions. Furthermore, the reimbursement policy for migrant workers who suffered from TB should be ameliorated.

Understanding Barriers to and Facilitators of Case Management in Primary Care: A Systematic Review and Thematic Synthesis

PURPOSE

Despite evidence on the benefits of case management for the care of patients with complex needs in primary care, implementing the program-necessary to achieve its benefits-has been challenging worldwide. Evidence on factors affecting implementation remains disparate. Accordingly, the objective of this systematic review was to identify barriers to and facilitators of case management, from the perspectives of health care professionals, in primary care settings around the world.

METHODS

We conducted a systematic review and thematic synthesis of qualitative findings. In collaboration with 2 librarians, we searched 3 electronic databases (MEDLINE, CINAHL, EMBASE) for studies related to factors affecting case management function in primary care. Two researchers screened titles, abstracts, and full texts for inclusion, then assessed included studies for quality. Results from included studies were synthesized by thematic synthesis, and a framework was developed.

RESULTS

Of 1,640 unique records identified, 22 studies, originating from 6 countries, met the inclusion criteria. We identified 9 barriers and facilitators: family context; policy and available resources; physician buy-in and understanding of the case manager role; relationship building; team communication practices; autonomy of case managers; training in technology; relationships with patients; and time pressure and workload. We describe these factors, then present a framework demonstrating the relationships among them.

CONCLUSIONS

Our study's findings show that multiple factors influence case management implementation. These findings have implications for researchers, clinicians, and policy makers who strive to implement or reform case management programs in local or larger primary care settings.

The effectiveness of case management interventions for the homeless, vulnerably housed and persons with lived experience: A systematic review

BACKGROUND

Individuals who are homeless or vulnerably housed are at an increased risk for mental illness, other morbidities and premature death. Standard case management interventions as well as more intensive models with practitioner support, such as assertive community treatment, critical time interventions, and intensive case management, may improve healthcare navigation and outcomes. However, the definitions of these models as well as the fidelity and adaptations in real world interventions are highly variable. We conducted a systematic review to examine the effectiveness and cost-effectiveness of case management interventions on health and social outcomes for homeless populations.

METHODS AND FINDINGS

We searched Medline, Embase and 7 other electronic databases for trials on case management or care coordination, from the inception of these databases to July 2019. We sought outcomes on housing stability, mental health, quality of life, substance use, hospitalization, income and employment, and cost-effectiveness. We calculated pooled random effects estimates and assessed the certainty of the evidence using the GRADE approach. Our search identified 13,811 citations; and 56 primary studies met our full inclusion criteria. Standard case management had both limited and short-term effects on substance use and housing outcomes and showed potential to increase hostility and depression. Intensive case management substantially reduced the number of days spent homeless (SMD -0.22 95% CI -0.40 to -0.03), as well as substance and alcohol use. Critical time interventions and assertive community treatment were found to have a protective effect in terms of rehospitalizations and a promising effect on housing stability. Assertive community treatment was found to be cost-effective compared to standard case management.

CONCLUSIONS

Case management approaches were found to improve some if not all of the health and social outcomes that were examined in this study. The important factors were likely delivery intensity, the number and type of caseloads, hospital versus community programs and varying levels of participant needs. More research is needed to fully understand how to continue to obtain the increased benefits inherent in intensive case management, even in community settings where feasibility considerations lead to larger caseloads and less-intensive follow-up.

Costs and effects of interventions targeting frequent presenters to the emergency department: a systematic and narrative review

Background

Previous systematic reviews have examined the effectiveness of interventions for frequent presenters to the Emergency Department (ED) but not the costs and cost-effectiveness of such interventions.

Method

A systematic literature review was conducted which screened the following databases: Pubmed, Medline, Embase, Cochrane and Econlit. An inclusion and exclusion criteria were developed following PRISMA guidelines. A narrative review methodology was adopted due to the heterogeneity of the reporting of the costs across the studies.

Results

One thousand three hundred eighty-nine papers were found and 16 were included in the review. All of the interventions were variations of a case management approach. Apart from one study which had mixed results, all of the papers reported a decrease in ED use and costs. There were no cost effectiveness studies.

Conclusion

The majority of interventions for frequent presenters to the ED were found to decrease ED use and cost. Future research should be undertaken to examine the cost effectiveness of these interventions.

An evaluation of the use of management care plans for people who frequently attend the emergency department

OBJECTIVE

To evaluate the use of management plans for people who frequently attend the emergency department (ED).

BACKGROUND

Management plans are used to decrease ED utilisation by people who frequently attend. There is limited evidence regarding the use management plans for this population and the perspectives of staff who use them has previously not been considered.

DESIGN

A descriptive observational design including before and after measures of attendance (November 2010 to September 2014) and survey of staff perceptions (July to November 2014). The setting was a major metropolitan hospital ED in Australia.

METHODS

The date for commencement of each plan was determined. Data were extracted regarding ED attendance 12 months before and after implementation. Staff perspectives were obtained via an online survey.

RESULTS

Fifty-seven patients made 1482 ED attendances. Of these 830 occurred in the 12 months before the management plan was implemented and 652 during the 12 months after. The number of attendances per patient decreased from a median of 11 to 4. Staff considered management plans to be beneficial to care planning practices and individual patient outcomes.

CONCLUSIONS

Management plans were acceptable to staff, and implementation of management plans was associated with a decrease in ED attendance.

Lessons learned from piloting a pain assessment program for high frequency emergency department users

Background and aims Chronic pain (CP) management presents a challenge for the healthcare system as many individuals experiencing CP cannot access appropriate services. Consequently, individuals may visit emergency departments (EDs) to address their CP, even though this setting is not the most appropriate. CP was identified as a common factor amongst patients with repeat ED use at a hospital in Ottawa, Canada. Thus, staff of the Pain Clinic developed the Rapid Interdisciplinary Pain Assessment Program to improve the care of patients with CP who had a minimum of 12 ED visits in the previous year, who were considered high frequency users (HFUs) of the ED. This evaluation was conducted to guide program improvements in advance of a clinical trial. The results are reported here in order to describe lessons that could be applied to the development of similar programs. The benefits of the program in reducing ED use, pain intensity, disability, and psychological distress have been described elsewhere (Rash JA et al. Pain Res Manag 2018:1875967). Methods Thirty-five people completed semi-structured interviews or a focus group, including eight patients, six ED staff, four primary care physicians (PCP), five Pain Clinic physicians, and 12 program staff members. Questions focused on the program's implementation, as well as strengths and areas for improvement. Results The program was generally consistent in offering the intended patients the services that were planned. Specifically, patients received an interdisciplinary assessment that informed the development of an assessment and treatment plan. These plans were shared with the PCP and added to the patient's hospital electronic medical record. Patients also received education about CP and had access to medical pain management, substance use, and psychological treatments. Inter-professional communication was facilitated by case conferences. Numerous aspects of the program were perceived as helpful, such as the quick access to services, the comprehensive assessment and treatment plans, the individualized treatment, the use of an interdisciplinary approach to care, and the communication and relationships with other care providers. However, challenges arose with respect to the coordination of services, the addition of supplementary services, the accessibility of the program, patients' perceptions of being misunderstood, communication, and relationship-building with other service providers. Conclusions The program sought to improve the care of HFUs with CP and reduce their ED use for CP management. The program had numerous strengths, but also encountered challenges. Developers of programs for HFUs with CP are encouraged to consider these challenges and suggested solutions. These programs have the potential to deliver effective healthcare to individuals with CP and reduce ED overutilization. Implications Our findings suggest that the following points should be considered in the development of similar programs: the inclusion of a case manager; the use of strategies to ensure inter-professional communication, such as secure electronic consultation, approaches to allow access to assessment and treatment plans, and offering a range of modalities for communication; holding regular case conferences; determining the appropriate types of services to offer; and working to address patients' fears of being labelled.

Case management programs in emergency department to reduce frequent user visits: a systematic review

BACKGROUND AND AIM

Inappropriate visits to the Emergency Department (ED) by frequent users (FU) are a common phenomenon because this service is perceived as a rapid and concrete answer to any health and social issue not necessarily related to urgent matters. Could Case Management (CM) programs be a suitable solution to address the problem? The purpose is to examine how CM programs are implemented to reduce the number of FU visits to the ED.

METHODS

PubMed, CINAHL and EMBASE were consulted up to December 2018. This review follows PRISMA guidelines for systematic review, as first outcomes were considered the impact of CM interventions on ED utilization, costs and composition of teams.

RESULTS

Fourteen studies were included and they showed patients with common characteristics but the FU definition wasn't the same. Twelve studies provided a reduction of ED utilization and seven studies a cost reduction. The main tool used is the individual care plan with telephone contact, supportive group therapy, facilitated contacts with healthcare providers and informatics system for immediate identification. The CM team composition is heterogeneous, even if nurses are considered the most used professional figures.

CONCLUSIONS

In contrast with a standardized method, a customized approach of CM program helps frequent users in finding an appropriate answer to their needs, thus decreasing inappropriate visits to the ED.

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.

Self-Reported Quality, Health, and Cost-Related Outcomes of Care Coordination Among Patients with Complex Health Needs

Care coordination is an increasingly popular strategy to help patients with complex health conditions manage their diseases more effectively. The purpose of the current study was to assess associations between patient-reported receipt of care coordination and their experiences of health, health care quality, and cost-related outcomes. Regression analyses of data from 431 patients across 13 Texas providers indicate that patients who reported receiving care coordination had higher odds of perceiving having enough information about how to manage their conditions (OR 2.02, P < .01), having information about education and treatments available (OR 1.87, P < .01), and reporting better access to care (beta = .27, P < .01). Receipt of care coordination was not associated with patients' reports of how up-to-date their doctors were about care from other providers, patients' health-related functioning, or patients' intention to return to the emergency department. Patients' reasons for intending to return to the emergency department included the speed of care there relative to alternatives and satisfaction with the quality of care they had received previously in the emergency department. Results suggest that care coordination in usual practice may improve patient preventive care, but not some other health or cost-related outcomes.

Interventions to Decrease Use in Prehospital and Emergency Care Settings Among Super-Utilizers in the United States: A Systematic Review

Interest in high users of acute care continues to grow as health care organizations look to deliver cost-effective and high-quality care to patients. Since “super-utilizers” of acute care are responsible for disproportionately high health care spending, many programs and interventions have been implemented to reduce medical care use and costs in this population. This article presents a systematic review of the peer-reviewed and grey literature on evaluations of interventions to decrease prehospital and emergency care use among U.S. super-utilizers. Forty-six distinct evaluations were included in the review. The most commonly evaluated intervention was case management. Although a number of interventions reported reductions in prehospital and emergency care utilization and costs, methodological and study design weaknesses—especially regression to the mean—were widespread and call into question reported positive findings. More high-quality research is needed to accurately assess the impact of interventions to reduce prehospital and emergency care use in the super-utilizer population.

Michigan Emergency Department Leader Attitudes Toward and Experiences With Clinical Pathways to Guide Admission Decisions: A Mixed-methods Study

OBJECTIVES

The objective was to characterize emergency department (ED) leader's attitudes toward potentially avoidable admissions and experiences with the use of clinical pathways to guide admission decisions, including the challenges and successes with implementation of these pathways.

METHODS

A mixed-methods study of Michigan ED leaders was conducted. First, a cross-sectional Web-based survey was distributed via e-mail to all 135 hospital-based EDs in the state. Descriptive statistics were calculated. Survey participants who provided contact information were considered eligible for follow-up. Semistructured interviews were conducted by telephone until thematic saturation was reached. Interviews were recorded, transcribed verbatim, reviewed for accuracy, and thematically coded. Representative quotes were extracted for reporting.

RESULTS

Survey responses were received from 64 ED leaders (48% eligible response rate). Semistructured interviews were conducted with a purposeful sample of 11 of the 29 representatives willing to be contacted. Eight sites implemented clinical care pathways as a strategy to reduce avoidable admissions. Pathways were developed for high-frequency conditions. Many pathways were multidisciplinary, incorporating case managers and outpatient care providers, which was thought to improve acceptability. Five models of care emerged 1) standardized care, 2) observation medicine, 3) enhanced follow-up, 4) care coordination, and 5) comprehensive programs. We identified barriers to and facilitators of discharging a patient from the ED when an admission otherwise could be avoided. Barriers included limited access to follow-up, lack of care coordination, and lack of trust in patient's ability to provide self-care or navigate the system. Facilitators included strong relationships with outpatient providers, care coordination, and shared decision making.

CONCLUSIONS

Potential solutions to help avoid hospitalization from the ED include multidisciplinary clinical care pathways. Successful pathways emerged from bringing stakeholders from the ED, hospital, and health care community together. Additionally, emergency providers need systems and supports in place to help their patients navigate follow-up care in a timely fashion.

Navigating medically complex patients through system barriers: Patients’ perspectives on care coordination

Introduction

Care coordination can improve healthcare quality and reduce costs. The objective of this study was to provide a qualitative understanding of the most helpful coordination services as experienced by patients receiving these services to reduce emergent hospital use.

Methods

Using case study methodology, we conducted focus group conversations with 51 care coordination patients and semi-structured interviews with 29 care coordinators at nine sites throughout Texas. The study team performed constant comparative analysis, beginning with start codes based on prior research.

Results

On average, focus group participants were 47 years old. The majority of participants reported a high school or General Equivalency Diploma level of education or less (84%), an annual income less than $14,999 (87%), and living with multiple chronic health conditions (60%). The majority (85%) of care coordinators reported backgrounds in nursing or social work. In our analysis, themes of what patients found most helpful fell under a broad social support framework (instrumental, informational, emotional, and advocacy) that care coordinators were uniquely situated to provide.

Discussion

Our paper adds to existing evidence by providing perspectives of patients with complex medical and non-medical needs about which care coordination services are most helpful. In this sample, patients with high needs describe reliance on professional sources, rather than their own social networks, to address several aspects of social support and to help meet non-health-related, as well as health-related needs. This can inform providers’ approaches to treatment as well as program administrators’ decisions about addressing and prioritizing services in care coordination programs.

Health care costs of case management for frequent users of the emergency department: Hospital and insurance perspectives

BACKGROUND

In most emergency departments (EDs), few patients account for a relatively high number of ED visits. To improve the management of these patients, the university hospital of Lausanne, Switzerland, implemented an interdisciplinary case management (CM) intervention. This study examined whether the CM intervention-compared with standard care (SC) in the ED-reduced costs generated by frequent ED users, not only from the hospital perspective, but also from the third-party payer perspective, that is, from a broader perspective that takes into account the costs of health care services used outside the hospital offering the intervention.

METHODS

In this randomized controlled trial, 250 frequent ED users (>5 visits during the previous 12 months) were allocated to either the CM or the SC group and followed up for 12 months. Cost data were obtained from the hospital's analytical accounting system for the entire sample and from health insurance companies for a subgroup (n = 140). Descriptive statistics and multivariate regressions were used to make comparisons between groups and assess the contribution of patient characteristics to the main cost components.

RESULTS

At the end of the 12-month follow-up, 115 patients were in the CM group and 115 in the SC group (20 had died). Despite differences in economic costs between patients in the CM intervention and the SC groups, our results do not show any statistically significant reduction in costs associated with the intervention, either for the hospital that housed the intervention or for the third-party payer. Frequent ED users were big users of health services provided by both the hospital and community-based services, with 40% of costs generated outside the hospital that housed the intervention. Higher age, Swiss citizenship, and having social difficulty increased costs significantly.

CONCLUSIONS

As the role of the CM team is to guide patients through the entire care process, the intervention location is not limited to the hospital but often extends into the community.

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)

Using case management in a universal health coverage system to improve quality of life of frequent Emergency Department users: a randomized controlled trial

Purpose

Frequent Emergency Department users are likely to experience poor quality of life (QOL). Case management interventions are efficient in responding to the complex needs of this population, but their effects on QOL have not been tested yet. Therefore, the aim of our study was to examine to what extent a case management intervention improved frequent Emergency Department users’ QOL in a universal health coverage system.

Methods

Data were part of a randomized controlled trial designed to improve frequent Emergency Department users’ QOL at the Lausanne University Hospital, Switzerland. A total of 250 frequent Emergency Department users (≥ 5 attendances during the previous 12 months) were randomly assigned to the control (n = 125) or the intervention group (n = 125). The latter benefited from case management intervention. QOL was evaluated using the WHOQOL-BREF at baseline, two, five and a half, nine, and twelve months later. It included four dimensions: physical health, psychological health, social relationship, and environment. Linear mixed-effects models were used to analyze the change in the patients’ QOL over time.

Results

Patients’ QOL improved significantly (p < 0.001) in both groups for all dimensions after two months. However, environment QOL dimension improved significantly more in the intervention group after 12 months.

Conclusions

Environment QOL dimension was the most responsive dimension for short-term interventions. This may have been due to case management’s assistance in obtaining income entitlements, health insurance coverage, stable housing, or finding general health care practitioners. Case management in general should be developed to enhance frequent users’ QOL.

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.

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.

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.

The HOME Team: Evaluating the Effect of an EMS-based Outreach Team to Decrease the Frequency of 911 Use Among High Utilizers of EMS

OBJECTIVES

The San Francisco Fire Department's (SFFD; San Francisco, California USA) Homeless Outreach and Medical Emergency (HOME) Team is the United States' first Emergency Medical Services (EMS)-based outreach effort using a specially trained paramedic to redirect frequent users of EMS to other types of services. The effectiveness of this program at reducing repeat use of emergency services during the first seven months of the team's existence was examined.

METHODS

A retrospective analysis of EMS use frequency and demographic characteristics of frequent users was conducted. Clients that used emergency services at least four times per month from March 2004 through May 2005 were contacted for intervention. Patterns for each frequent user before and after intervention were analyzed. Changes in EMS use during the 15-month study interval was the primary outcome measurement.

RESULTS

A total of 59 clients were included. The target population had a median age of 55.1 years and was 68% male. Additionally, 38.0% of the target population was homeless, 43.4% had no primary care, 88.9% had a substance abuse disorder at time of contact, and 83.0% had a history of psychiatric disorder. The HOME Team undertook 320 distinct contacts with 65 frequent users during the study period. The average EMS use prior to HOME Team contact was 18.72 responses per month (SD=19.40), and after the first contact with the HOME Team, use dropped to 8.61 (SD=10.84), P<.001.

CONCLUSION

Frequent users of EMS suffer from disproportionate comorbidities, particularly substance abuse and psychiatric disorders. This population responds well to the intervention of a specially trained paramedic as measured by EMS usage. Tangherlini N , Villar J , Brown J , Rodriguez RM , Yeh C , Friedman BT , Wada P .

A Randomized Controlled Trial of a Citywide Emergency Department Care Coordination Program to Reduce Prescription Opioid Related Emergency Department Visits

BACKGROUND

Increasing prescription overdose deaths have demonstrated the need for safer emergency department (ED) prescribing practices for patients who are frequent ED users.

OBJECTIVES

We hypothesized that the care of frequent ED users would improve using a citywide care coordination program combined with an ED care coordination information system, as measured by fewer ED visits by and decreased controlled substance prescribing to these patients.

METHODS

We conducted a multisite randomized controlled trial (RCT) across all EDs in a metropolitan area; 165 patients with the most ED visits for complaints of pain were randomized. For the treatment arm, drivers of ED use were identified by medical record review. Patients and their primary care providers were contacted by phone. Each patient was discussed at a community multidisciplinary meeting where recommendations for ED care were formed. The ED care recommendations were stored in an ED information exchange system that faxed them to the treating ED provider when the patient presented to the ED. The control arm was subjected to treatment as usual.

RESULTS

The intervention arm experienced a 34% decrease (incident rate ratios = 0.66, p < 0.001; 95% confidence interval 0.57-0.78) in ED visits and an 80% decrease (odds ratio = 0.21, p = 0.001) in the odds of receiving an opioid prescription from the ED relative to the control group. Declines of 43.7%, 53.1%, 52.9%, and 53.1% were observed in the treatment group for morphine milligram equivalents, controlled substance pills, prescriptions, and prescribers, respectively.

CONCLUSION

This RCT showed the effectiveness of a citywide ED care coordination program in reducing ED visits and controlled substance prescribing.

Trust in health care providers: factors predicting trust among homeless veterans over time

We examined whether a combination of predisposing, enabling, need, and primary care experience variables would predict trust in medical health care providers for homeless veterans over 18 months. Linear mixed model analysis indicated that, among these variables, race, social support, service-connected disability status, and satisfaction and continuity with providers predicted trust in provider over time. Trust in providers improved during the initial stages of the relationship between patient and provider and then declined to slightly below baseline levels over time. Further research is needed to determine generalizability and effects of provider trust on patient health care status over longer periods of time.

Variations in Resource Intensity and Cost Among High Users of the Emergency Department

OBJECTIVES

High users of emergency department (ED) services are often identified by number of visits per year, with little exploration of the distribution/pattern of visits over time. The purpose of this study was to examine patient- and encounter-level factors and costs related to periods of short-term resource intensity among high users of the ED within a tertiary care teaching facility.

METHODS

We identified all adults with at least three visits to the Ottawa Hospital ED within a 1-year period from April 1, 2012, to March 31, 2013. Within this high-user cohort, we then measured intensity of use by calculating average daily visit rates to identify individuals with a cluster of ED visits. Those with at least three ED visits/7 days at any point during follow-up were considered patients with clustered ED use (i.e., a period of short-term resource intensity). Detailed clinical and administrative data were used to compare patient- and encounter-level characteristics and cost profiles between the clustered and nonclustered groups. Analyses were repeated using varying cut points to define high users (at least five and at least eight visits per year).

RESULTS

Of the 16,153 patients identified as high ED users during the study period, 13.5% had their visits clustered within a short period of time. These clustered users were more likely to be homeless, to require psychiatric services, and to leave without being seen by a physician and less likely to be admitted to the hospital. Approximately one in three (31.2%) high ED users with clustered visits returned for the same medical problem (namely pain-related disorders, shortness of breath, and cellulitis) within a 1-week period. Similar trends were observed when the high-user cohort was restricted to those with at least five and at least eight ED visits/year. Finally, patients with short-term intensity periods had lower direct and indirect costs per encounter than those without.

CONCLUSIONS

Using a novel methodology that accounts for both number and intensity of ED encounters over time, we were able to identify specific subpopulations of high ED users. Further work is required to determine if this methodology has utility for targeting care pathways within this heterogeneous and high-risk patient group.

Impact of a Chronic Pain Protocol on Emergency Department Utilization

OBJECTIVES

Patients suffering from chronic painful conditions frequently present to the emergency department (ED) for pain control. In an effort to better manage these patients we implemented and measured the effect of enrollment in a chronic pain protocol in a single ED.

METHODS

A retrospective (pre) and prospective (post) study design was utilized. We identified 46 frequent ED users suffering from chronic painful conditions. We then retrospectively documented their ED use and prescription controlled substance use for 6 months prior to enrollment in a chronic pain protocol and then 6 months postenrollment.

RESULTS

Preenrollment participating patients visited the ED on average 6.2 times in a 6-month period. Postenrollment their mean number of visits in the following 6 months decreased significantly to 2.2 times, or a 65% decrease (p < 0.001). Similarly, preenrollment, the patients were prescribed a median of 664 controlled substance pills in the entire state compared to 471 pills in the 6-month period postenrollment, or a 29% decrease (p < 0.022).

CONCLUSIONS

Through instituting a chronic pain protocol, we found significant reductions in the number of return visits to a single ED and the number of controlled substance medications prescribed by all providers. Additional studies using similar protocols could help establish their impact on the care of patients suffering from chronic pain and the potential to reduce healthcare costs, ED overcrowding, and prescription drug abuse.

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.
