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

Help-seeking in A&E for Functional Neurological Disorder (FND): a mixed methods study of patient experiences of a war on two fronts

OBJECTIVE

This mixed-method study aimed to i) describe characteristics of those who attend A&E frequently (FAs) with and without Functional Neurological Disorder (FND); ii) to explore patients' with FND's experiences of help-seeking in A&E.

METHODS AND MEASURES

First, a database of NHS FAs (10+ times in a year; n = 99) from one hospital was analysed. Next, FAs with FND (n = 6) were interviewed about their help-seeking.

RESULTS

From stage 1, 61% of all FAs were female, had visited A&E a mean of 16 times in the past 12 months and had been referred to a wide range of clinics. No significant differences were found between FND (n = 11) and non FND patients (n = 88). In Stage 2, thematic analysis described four main themes: i) 'symptom experience'; ii) 'feelings of isolation'; iii) 'Healthcare Professional (HCP) barriers to care'; iv) 'HCP perseverance'. Transcending these themes was a transition from uncertainty to judgement as patients eventually obtained a diagnosis of FND. Overarching all themes was the sense of FND as a war on two fronts as patients battled both their symptoms and the health care system.

CONCLUSION

Help seeking for FND involves a battle which may be improved by educating HCPs and offering a specialised clinic.

Setting up Functional Neurological Disorder Treatment Services: Questions and Answers

Functional neurologic disorder (FND) is commonly encountered across outpatient and inpatient medical settings. Given the potential for a high burden of disability in some patients and mounting evidence for the efficacy of FND-specific multidisciplinary treatment services, expanding clinical services for this population is a necessity. In this perspective article, we discuss considerations for creating FND services, including the types of services that exist, how to start, how to identify appropriate referrals, and how to develop and monitor individualized treatment plans. In addition, we discuss how this effort can be done sustainably - balancing patient needs with limited healthcare resources.

Use of urgent, emergency and acute care by mental health service users: A record-level cohort study

BACKGROUND

People with serious mental illness experience worse physical health and greater mortality than the general population. Crude rates of A&E attendance and acute hospital admission are higher in people with serious mental illness than other hospital users. We aimed to further these findings by undertaking a standardised comparison of urgent and emergency care pathway use among users of mental health services and the general population.

METHODS

Retrospective cohort analysis using routine data from 2013-2016 from the CUREd dataset for urgent and emergency care contacts (NHS 111, ambulance, A&E and acute admissions) and linked mental health trust data for Sheffield, England. We compared annual age- and sex-standardised usage rates for each urgent and emergency care service between users of mental health services and those without a recent history of mental health service use.

RESULTS

We found marked differences in usage rates for all four urgent and emergency care services between the general population and users of mental health services. Usage rates and the proportion of users were 5-6 times and 3-4 times higher in users of mental health services, respectively, for all urgent and emergency care services. Users of mental health services were often more likely to experience the highest or lowest acuity usage characteristics.

CONCLUSIONS

Current users of mental health services were heavily over-represented among urgent and emergency care users, and they made more contacts per-person. Higher service use among users of mental health services could be addressed by improved community care, more integrated physical and mental health support, and more proactive primary care. A complex pattern of service use among users of mental health services suggests this will need careful targeting to reduce avoidable contacts and optimise patient outcomes.

Prevalence of medically unexplained symptoms in adults who are high users of healthcare services and magnitude of associated costs: a systematic review

INTRODUCTION

Medically unexplained symptoms (MUS) is a common clinical syndrome in primary and secondary healthcare service. Outcomes for patients with persistent MUS include increased disability, poorer quality of life and higher healthcare costs. The aim of this systematic review was to determine the prevalence of MUS in patients who are high users of healthcare or high-cost patients in comparison with routine users and the magnitude of associated costs.

DESIGN

A systematic review of the available literature.

DATA SOURCES AND ELIGIBILITY CRITERIA

The following electronic databases were systematically searched without language restriction from inception to June 2018 and updated on 22 October 2021: MEDLINE, PsycINFO, EMBASE, CINAHL and PROSPERO. Inclusion criteria included studies investigating adults aged ≥18 years, who were high healthcare users or accrued high healthcare costs, in which the prevalence and/or associated costs of MUS was quantified. Two reviewers independently extracted information on study characteristics, exposure and outcomes.

RESULTS

From 5622 identified publications, 25 studies from 9 countries involving 31 650 patients were selected for inclusion. Due to high risk of bias in many studies and heterogeneity between studies, results are described narratively. There were wide variations in prevalence estimates for MUS in high users of healthcare (2.9%-76%), but MUS was more prevalent in high use groups compared with low use groups in all but one of the 12 studies that included a comparator group. Only three studies investigated healthcare costs associated with MUS, and all three reported greater healthcare costs associated with MUS.

CONCLUSION

MUS has been found to be more prevalent in high use healthcare populations than comparator groups, but the magnitude of difference is difficult to estimate due to considerable heterogeneity between studies and potential for bias. Future studies should prioritise a standardised approach to this research area, with agreed definitions of MUS and high healthcare use.

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.

Heterogeneity of reasons for attendance in frequent attenders of emergency departments and its relationship to future attendance

BACKGROUND

EDs globally are under increasing pressure through rising demand. Frequent attenders are known to have complex health needs and use a disproportionate amount of resources. We hypothesised that heterogeneity of patients' reason for attendance would be associated with multimorbidity and increasing age, and predict future attendance.

METHOD

We analysed an anonymised dataset of all ED visits over the course of 2014 in Yorkshire, UK. We identified 15 986 patients who had five or more ED encounters at any ED in the calendar year. Presenting complaint was categorised into one of 14 categories based on the Emergency Care Data Set (ECDS). We calculated measures of heterogeneity (count of ECDs categories and entropy of categories) and examined their relationship to total number of ED visits and to patient characteristics. We examined the predictive value of these and other features on future attendance.

RESULTS

Most frequent attenders had more than one presenting complaint type. Heterogeneity increased with number of attendances, but heterogeneity adjusted for number of attendances did not vary substantially with age or sex. Heterogeneity was associated with the presence of one or more contacts for a mental health problem. For a given number of attendances, prior mental health contact but not heterogeneity was associated with further attendance.

CONCLUSIONS

Heterogeneity of presenting complaint can be quantified and analysed for ED use: it is increased where there is a history of mental disorder but not with age. This suggests it reflects more than the number of medical conditions.

Functional neurological disorder in the emergency department

We provide a narrative review of functional neurological disorder (FND, or conversion disorder) for the emergency department (ED). Diagnosis of FND has shifted from a "rule-out" disorder to one now based on the recognition of positive clinical signs, allowing the ED physician to make a suspected or likely diagnosis of FND. PubMed, Google Scholar, academic books, and a hand search through review article references were used to conduct a literature review. We review clinical features and diagnostic pitfalls for the most common functional neurologic presentations to the ED, including functional limb weakness, functional (nonepileptic) seizures, and functional movement disorders. We provide practical advice for discussing FND as a possible diagnosis and suggestions for initial steps in workup and management plans.

The effectiveness of an emergency department nursing intervention on psychological symptoms and self-care capacities: A randomized controlled study protocol

BACKGROUND

We carried out a randomized trial of an emergency department (ED)-based nursing intervention to evaluate the impact of an ED nursing intervention on ED revisits, patient perceptions of continuity of care, illness perceptions, self-care capacities and psychological symptoms.

METHOD

We conducted a randomized controlled trial to compare the ED-based intervention with usual care. The protocol was reviewed and approved by the Research Ethics Board of the Huzhou Central Hospital & Affiliated Central Hospital Huzhou University (K901923-021), each participant signed a written consent before participating, and SPIRIT guidelines were followed throughout. To be eligible, patients ready for discharge from the ED had to be at risk for ED return based on 2 criteria: at least one ED visit during the year prior to the initial visit, and current treatment with at least 6 medications. Exclusion criteria included cognitive problems (e.g., dementia) that would preclude provision of informed consent either noted in the medical chart or identified based on the clinical judgment of the project nurse. To avoid multiple interveners for the same patient, we also excluded patients already receiving other regular follow-up (e.g., at a specialized clinic in the hospital or from external resources). The major outcomes were assessed with the Heart Continuity of Care Questionnaire, the Illness Perception Questionnaire-Revised, the Therapeutic Self-Care Tool, the Hospital Anxiety and Depression Scale, and the Self-Reported Medication-Taking Scale.

RESULTS

Two hundred patients who met the inclusion criteria were included in our study, Table 1 showed the effects of nursing intervention on measures of clinical outcomes.

DISCUSSION

The ED is a major entry point into the health care system of many countries. Unnecessary ED revisits may result in overcrowding, increased waiting time, and failure to provide appropriate emergency care. The ED-based interventions literature focuses primarily on service use and ways to reduce ED revisits, with very little focus on impacting secondary outcomes. Because of their potential link with health service utilization, secondary outcomes such as perceived continuity of care, illness perceptions, self-care capacities, psychological symptoms and medication adherence might influence ED revisits. Future research was needed to better understand the complex relationship between ED utilization and a variety of intermediary factors in order to develop interventions that will optimize ED utilization.

Higher prescription of antidepressants and/or anxiolytics among chronic obstructive pulmonary disease patients

Background:

Chronic obstructive pulmonary disease (COPD) is often accompanied by psychiatric problems, such as depression and anxiety, affecting both treatment outcomes and mortality. Evidence for the number of COPD patients using medication for these disorders is sparse. In this study, chronic antidepressant (ATD) and anxiolytic (ANX) drug use – to identify depression and anxiety – among COPD patients was compared with subjects with or without other chronic diseases.

Methods:

The NControl database containing prescription data of 800 pharmacies including 7 million individuals in The Netherlands was used. Patients of age 55+ years who received frequent prescriptions – at least two/year in 5 out of 6 years – for COPD medication, dermatological drugs, disease-modifying antirheumatic drugs (DMARDs), statins and oral glucose-lowering medication were analyzed for concomitant chronic use of ATDs and ANXs between 1 January 2013 and 1 January 2019. All other subjects aged 55+ years were included as a control group (control group 1). This group was further stratified into a group of subjects that received frequent prescriptions of any kind (control group 2).

Results:

15.2% of the patients that receive COPD treatment (n = 96,319), 15.3% of subjects that are treated for dermatological problems (n = 62,865), 13.2% of subjects that receive DMARDs (n = 7900), 11.6% of statins users (n = 422,376) and 11.4% of oral glucose-lowering medication users (n = 165,975) are also chronically treated for depression or anxiety, compared with 2.6% (control group 1; n = 3,290,608) and 11.4% (control group 2; n = 757,947). In general, female and 75+ years aged subjects showed a higher risk for using ATDs and ANXs chronically. In the COPD and the dermatological patient group the risk was the highest compared with the other patient groups.

Conclusions:

The rates of chronic ATD and ANX use and the risk of having depression and/or anxiety are especially high in COPD patients, indicating that psychiatric problems are more common in COPD than in most other chronic diseases. In general, age and gender strongly influence the risk of chronically using ATDs and ANXs.

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.

Relationships Between Somatic Symptoms and Panic-Agoraphobic Spectrum Among Frequent Attenders of the General Practice in Italy

Frequent attenders (FAs) of general practitioners (GPs) often complain of nonspecific physical symptoms that are difficult to define according to typical medical syndromes criteria but could be acknowledged as atypical manifestations of mental disorders. We investigated the possible correlation between somatic symptoms and panic-agoraphobic spectrum symptoms in a sample of 75 FAs of GPs in Italy, with particular attention to the impact on functional impairment. Assessments included the Patient Health Questionnaire, Panic-Agoraphobic Spectrum-Self-Report (PAS-SR) lifetime version, Global Assessment of Functioning, and Clinical Global Impression. The PAS-SR total and domains scores were significantly higher among low-functioning FAs, especially anxious somatizations, hypochondriasis, anxious expectation, and reassurance orientation domains, suggesting this undetected symptom may determine the selective attention to the physical symptoms, illness-phobic/hypochondriac elaboration, and GP frequent attendance, often aimed at searching for reassurance, leading to severe impact on overall functioning and often inefficacious treatments.

Association between Subjective Well-Being and Frequent Dental Visits in the German Ageing Survey

The relationship between subjective well-being (SWB) and frequent attendance is understudied. This study used data from a large German sample of non-institutionalized individuals aged 40+ in 2014 (n = 7264). SWB was measured using the Satisfaction with Life Scale (SWLS) and the Positive and Negative Affect Schedule (PANAS). Number of self-reported dental visits in the past twelve months was used to measure the utilization frequency of dental services. Individuals with at least four dental visits in the preceding year (highest decile) were defined as frequent dental visits. Robustness checks were performed using alternative cut-offs to define frequent dental visits. Multiple logistic regressions showed that frequent dental visits (highest decile) were associated with less satisfaction with life [OR: 0.89, 95%-CI: 0.80–0.99] and higher negative affect [OR: 1.41, 95%-CI: 1.22–1.64], whereas it was not significantly associated with positive affect. Both associations depended on the cut-off chosen to define frequent dental visits. The present study highlights the association between SWB (particularly negative affect and low life satisfaction) and frequent dental visits. Further studies evaluating patients’ motivation for high dental service use are necessary to check the robustness of our findings.

Medically unexplained physical symptoms in patients visiting the emergency department: an international multicentre retrospective study

OBJECTIVE

The objective of this study was to assess the incidence and characteristics of patients presenting with physical symptoms that remain medically unexplained at the emergency department (ED).

PATIENTS AND METHODS

A retrospective chart study was carried out in three hospitals in The Netherlands and Belgium. All patients (age > 18 years) visiting the ED in 4 selected weeks in 2013 at the Erasmus University Medical Center (Erasmus MC) in Rotterdam, The Netherlands, and 1 selected week in 2013 at the Haaglanden Medical Center, Westeinde HMC in The Hague, The Netherlands, and the University Hospital Ghent (UZG), Belgium, were included. Descriptive statistics were used for data analysis.

RESULTS

A total of 2869 patients (Erasmus MC 1674, HMC 691, UZG 504) were included. Medically unexplained physical symptoms in the emergency department (EDMUPS) were present in 13.4% of all ED visits (Erasmus MC 12.5%, HMC 18.7%, UZG 9.1%). No EDMUPS were identified in trauma patients. When excluding trauma patients, EDMUPS were present in 18.5% (Erasmus MC 16.8%, HMC 26.5%, UZG 13.3%) of the visits. The characteristics of patients with and without EDMUPS differed significantly; patients with EDMUPS were more often younger, female, self-referred, frequent visitors, were prescribed less medication and more often had a psychiatric disease. Dutch and Belgian Hospital differed in the distribution of patients in triage categories and in the incidence of psychiatric illnesses.

CONCLUSION

Physical symptoms remain unexplained in a significant number of patients at the time of ED assessment.

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.

Patients with somatoform disorders: More frequent attendance and higher utilization in primary Out-of-Hours care?

BACKGROUND

One significant health policy challenge in many European countries at present is developing strategies to deal with the increase in patient attendance at Out-of-Hours care (OOHC), whether this is at OOHC-Centres in primary care settings or hospital emergency departments (ED). FAs (FAs) presenting in OOHC are a known challenge and previous studies have shown that FAs present more often with psychological problems and psychiatric comorbidities rather than severe physical complaints. FAs may be also contributing to the rising workload in OOHC-Centres in primary care. The aim of this study was to determine attendance frequencies and health problem presentation patterns for patients with and without somatoform disorders (ICD-10 F45 diagnoses) in OOHC-Centres in primary care. Some of these somatoform disorders may have a psychiatric character. Moreover, we wanted to compare health care utilization patterns (pharmacotherapy and hospitalizations) between these patients groups.

METHODS

Routine OOHC data from a large German statutory health insurance company in the federal state of Baden-Wuerttemberg were evaluated. 3,813,398 health insured persons were included in the data set from 2014. The data were initially made available for our study group in order to evaluate a comprehensive evaluation programme in German primary care, the "Hausarztzentrierte Versorgung" (HZV), loosely translated as "family doctor coordinated care". We used the ICD-10 codes F45.0-F45.9 in regular care to identify patients with somatoform disorders and compared their health care utilization patterns (attendance rates, diagnoses, prescriptions, hospitalization rates) in OOHC to patients without somatoform disorders. Attendance rates were calculated with multivariable regression models in order to adjust for age, gender, comorbidities and for participation in the HZV intervention.

RESULTS

350,528 patients (9.2%) of the 3,813,398 insured persons had an F45-diagnosis. In comparison with the whole study-sample, patients with an F45-diagnosis were on average seven years older (51.7 vs. 44.0 years; p<0,0001) and the percentage of women was significantly higher (70.1% vs 53.3%; p<0,0001). In OOHC, as opposed to normal office hours, the adjusted rate of patients with an F45-diagnosis was 60.6% higher (adjusted for age, gender and co-morbidity) than in the general study-sample. Accordingly, in OOHC, prescriptions for antidepressants, hypnotics, anxiolytics but also opioids were significantly higher than in the general study population i.e. those without F45- diagnoses. However, an F45 diagnosis was only made in 3.45% of all F45 patients seen in OOHC in 2014.

CONCLUSIONS

Patients with somatoform disorders were more FAs in both regular office hours and in OOHC in primary care settings. In OOHC, they are normally not identified as such because the somatoform illness is secondary to other acutely presenting symptoms such as pain. While it is acknowledged that it is difficult to make an exact diagnosis in this complex group of somatoform disorders in an OOHC setting, it is still important to develop continuing education programmes for medical staff working in OOHC, to support effective recognition and response to the specific needs of this complex patient group.

Exploring the Experiences of Persons Who Frequently Visit the Emergency Department for Mental Health-Related Reasons

In this qualitative study, the experiences of persons who frequently visit the emergency department (ED) for mental health-related reasons were explored. Interpretive Description guided the design, and data were collected through interviews with 10 adults who made 12+ ED visits within a 1-year time frame (2015). Thematic analysis was used to analyze data inductively. The participants' experiences were described with the help of three themes emerging from the data: The Experience, The Providers, and Protective Factors. The participants felt compelled to come to hospital. For them, every visit was necessary, and dismissal of their needs by staff was interpreted as disrespect and prejudice. We noted differences in ED utilization patterns according to psychiatric diagnosis, and more research is needed to explore the phenomenon of frequent use by particular patient populations. Furthermore, health care providers implementing interventions designed to improve emergency care should consider tailored approaches rather than a one-size-fits-all strategy.

CHOICE: Choosing Health Options In Chronic Care Emergencies

Background

Over 70% of the health-care budget in England is spent on the care of people with long-term conditions (LTCs), and a major cost component is unscheduled health care. Psychological morbidity is high in people with LTCs and is associated with a range of adverse outcomes, including increased mortality, poorer physical health outcomes, increased health costs and service utilisation.

Objectives

The aim of this programme of research was to examine the relationship between psychological morbidity and use of unscheduled care in people with LTCs, and to develop a psychosocial intervention that would have the potential to reduce unscheduled care use. We focused largely on emergency hospital admissions (EHAs) and attendances at emergency departments (EDs).

Design

A three-phase mixed-methods study. Research methods included systematic reviews; a longitudinal prospective cohort study in primary care to identify people with LTCs at risk of EHA or ED admission; a replication study in primary care using routinely collected data; an exploratory and feasibility cluster randomised controlled trial in primary care; and qualitative studies to identify personal reasons for the use of unscheduled care and factors in routine consultations in primary care that may influence health-care use. People with lived experience of LTCs worked closely with the research team.

Setting

Primary care. Manchester and London.

Participants

People aged ≥ 18 years with at least one of four common LTCs: asthma, coronary heart disease, chronic obstructive pulmonary disease (COPD) and diabetes. Participants also included health-care staff.

Results

Evidence synthesis suggested that depression, but not anxiety, is a predictor of use of unscheduled care in patients with LTCs, and low-intensity complex interventions reduce unscheduled care use in people with asthma and COPD. The results of the prospective study were that depression, not having a partner and life stressors, in addition to prior use of unscheduled care, severity of illness and multimorbidity, were independent predictors of EHA and ED admission. Approximately half of the cost of health care for people with LTCs was accounted for by use of unscheduled care. The results of the replication study, carried out in London, broadly supported our findings for risk of ED attendances, but not EHAs. This was most likely due to low rates of detection of depression in general practitioner (GP) data sets. Qualitative work showed that patients were reluctant to use unscheduled care, deciding to do so when they perceived a serious and urgent need for care, and following previous experience that unscheduled care had successfully and unquestioningly met similar needs in the past. In general, emergency and primary care doctors did not regard unscheduled care as problematic. We found there are missed opportunities to identify and discuss psychosocial issues during routine consultations in primary care due to the ‘overmechanisation’ of routine health-care reviews. The feasibility trial examined two levels of an intervention for people with COPD: we tried to improve the way in which practices manage patients with COPD and developed a targeted psychosocial treatment for patients at risk of using unscheduled care. The former had low acceptability, whereas the latter had high acceptability. Exploratory health economic analyses suggested that the practice-level intervention would be unlikely to be cost-effective, limiting the value of detailed health economic modelling.

Limitations

The findings of this programme may not apply to all people with LTCs. It was conducted in an area of high social deprivation, which may limit the generalisability to more affluent areas. The response rate to the prospective longitudinal study was low. The feasibility trial focused solely on people with COPD.

Conclusions

Prior use of unscheduled care is the most powerful predictor of unscheduled care use in people with LTCs. However, psychosocial factors, particularly depression, are important additional predictors of use of unscheduled care in patients with LTCs, independent of severity and multimorbidity. Patients and health-care practitioners are unaware that psychosocial factors influence health-care use, and such factors are rarely acknowledged or addressed in consultations or discussions about use of unscheduled care. A targeted patient intervention for people with LTCs and comorbid depression has shown high levels of acceptability when delivered in a primary care context. An intervention at the level of the GP practice showed little evidence of acceptability or cost-effectiveness.

Future work

The potential benefits of case-finding for depression in patients with LTCs in primary care need to be evaluated, in addition to further evaluation of the targeted patient intervention.

Association of general psychological factors with frequent attendance in primary care: a population-based cross-sectional observational study

Background

Whereas several studies have examined the association between frequent attendance in primary care and illness-specific psychological factors, little is known about the relation between frequent attendance and general psychological factors. Thus, the aim of this study was to investigate the association between being a frequent attender in primary care and general psychological factors.

Methods

Data were used from a large, population-based sample of community-dwelling individuals aged 40 and above in Germany in 2014 (n = 7,446). Positive and negative affect, life satisfaction, optimism, self-esteem, self-efficacy, and self-regulation were included as general psychological factors. The number of self-reported GP visits in the past twelve months was used to quantify frequency of attendance; individuals with more than 9 visits (highest decile) were defined as frequent attenders.

Results

Multiple logistic regressions showed that being a frequent attender was positively associated with less life satisfaction [OR: 0.79 (0.70–0.89)], higher negative affect [OR: 1.38 (1.17–1.62)], less self-efficacy [OR: 0.74 (0.63–0.86)], less self-esteem [OR: 0.65 (0.54–0.79)], less self-regulation [OR: 0.74 (0.60–0.91)], and higher perceived stress [OR: 1.46 (1.28–1.66)], after adjusting for sociodemographic factors, morbidity and lifestyle factors. However, frequent attendance was not significantly associated with positive affect and self-regulation.

Conclusions

The present study highlights the association between general psychological factors and frequent attendance. As frequent GP visits produce high health care costs and are potentially associated with increased referrals and use of secondary health care services, this knowledge might help to address these individuals with high needs.

Qualitative exploration of why people repeatedly attend emergency departments for alcohol-related reasons

Background

Understanding why people repeatedly attend Emergency Departments (EDs) for alcohol-related reasons is an important prerequisite to identifying ways of reducing any unnecessary demands on hospital resources. We use Andersen’s Behavioural Model of Health Services Use to explore factors that contributed to repeat ED attendances.

Methods

Qualitative interviews were conducted with 30 people who repeatedly attended EDs for alcohol-related reasons (≥10 attendances in the past 12 months). We recruited participants from 6 EDs in London, United Kingdom. Data on socio-demographic characteristics, substance use, contact with specialist addiction and other health services, most recent ED attendance, and previous ED attendances were analysed.

Results

Participants reported long-standing health problems, almost all were unemployed, and many had limited education and unstable housing. Most held positive health beliefs about EDs, despite some negative experiences. They reported limited community resources: poor social support, inaccessible primary care services, dislike or lack of information about specialist addiction services, and difficulties travelling to services. In contrast, EDs offered immediate, sympathetic care and free transport by ambulance. Participants’ perceived need for care was high, with physical injury and pain being the main reasons for ED attendance.

Conclusions

Push’ and ‘pull’ factors contributed to repeated ED use. ‘Push’ factors included individual-level problems and wider community service failings. ‘Pull’ factors included positive experiences of, and beliefs about, ED care. Community services need to better engage and support people with complex drinking problems, whilst ED staff can be more effective in referring patients to community-based services.

Emergency Department Use Among Adults with Autism Spectrum Disorders (ASD)

A cross-sectional analyses using Nationwide Emergency Department Sample (2006-2011) was conducted to examine the trends, type of ED visits, and mean total ED charges for adults aged 22-64 years with and without ASD (matched 1:3). Around 0.4% ED visits (n = 25,527) were associated with any ASD and rates of such visits more than doubled from 2006 to 2011 (2549-6087 per 100,000 admissions). Adults with ASD visited ED for: primary psychiatric disorder (15%ASD vs. 4.2%noASD), primary non-psychiatric disorder (16%ASD vs. 14%noASD), and any injury (24%ASD vs. 28%noASD). Mean total ED charges for adults with ASD were 2.3 times higher than for adults without ASD. Findings emphasize the need to examine the extent of frequent ED use in this population.

Brief case management versus usual care for frequent users of emergency departments: the Coordinated Access to Care from Hospital Emergency Departments (CATCH-ED) randomized controlled trial

Background

Frequent users of hospital emergency departments (EDs) are a medically and socially vulnerable population. This article describes the rationale for a brief case management intervention for frequent ED users with mental health and/or addiction challenges and the design of a randomized trial assessing its effectiveness.

Methods/Design

Eligible participants are adults in a large urban centre with five or more ED visits in the past year, with at least one prior visit for a mental health or addictions reason. Participants (N = 166) will be randomized to either 4 to 6 months of brief case management or usual care, and interviewed every 3 months for 1 year. Consent will be sought to access administrative health records. A subset of participants (N = 20) and service providers (N = 13) will participate in qualitative data collection.

Discussion

Addressing the needs of frequent ED users is a priority in many jurisdictions. This study will provide evidence on the effectiveness of brief case management, compared to usual care, on reducing ED visits among frequent ED users experiencing mental health or substance misuse problems, and inform policy and practice in this important area.

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.

Examining the need profiles of patients with multiple emergency department visits for mental health reasons: a cross-sectional study

OBJECTIVES

Study objectives were to: (1) provide an estimate of the prevalence of repeat emergency department (ED) use for mental health reasons among individuals enrolled in intensive case management programs; and (2) to identify socio-demographic, diagnostic, and service need characteristics associated with repeat ED visits among this service population.

METHODS

The study utilized administrative health data from community mental health organizations in Toronto, Canada on a sample of 2274 individuals enrolled in intensive case management programs. Patients with 2+ ED visits for mental health reasons within the prior 6 months were compared with individuals who had no ED visits or one visit on the basis of demographic, diagnostic and service need characteristics.

RESULTS

Approximately 6 % of intensive case management clients had two or more ED visits over a 6-month period. Membership in the repeat ED user group was associated with younger age (OR 0.98), a mood disorder (OR 1.58), being in service less than 1 year (OR 1.94) and unmet needs related to psychotic symptoms (OR 2.19), substance use (OR 2.27), and safety to self/others (OR 3.42).

CONCLUSIONS

The repeat ED user group within case management may have distinct need profiles that require different treatment responses. Moreover, clinical needs rather than psychosocial needs have the greatest relationship with repeat psychiatric ED utilization. These unmet needs suggest areas for future interventions aimed at reducing the use of ED services for mental health reasons and improving care for patients who repeatedly present at the ED.

The association between medically unexplained physical symptoms and health care use over two years and the influence of depressive and anxiety disorders and personality traits: a longitudinal study

Background

Medically unexplained physical symptoms (MUPS) are highly prevalent and are associated with frequent health care use (HCU). MUPS frequently co-occur with psychiatric disorders. With this study we examined the longitudinal association between MUPS and HCU over 2 years and the influence of depressive and anxiety disorders and personality traits on this association.

Methods

We analysed follow-up data from 2045 to 2981 participants from the Netherlands Study of Depression and Anxiety (NESDA), a multisite cohort study. The study population included participants with a current depressive and/or anxiety disorder, participants with a lifetime risk and/or subthreshold symptoms for depressive and/or anxiety disorders and healthy controls. HCU, measured with the Trimbos and iMTA questionnaire on Costs associated with Psychiatric illness (TIC-P), was operationalized as the number of used medical services and the number of associated contacts. MUPS were measured with the Four Dimensional Symptoms Questionnaire, depressive and anxiety disorders with the Composite International Diagnostic Interview and personality traits with the NEO Five-Factory Inventory. Measurements were taken at baseline, 1 and 2 years follow-up. We used generalized estimating equations (GEE), using HCU at all three measurements as (multivariate) outcome. GEE also takes into account the dependency of observations within participants.

Results

MUPS were positively associated with HCU over 2 years (medical services: RR 1.020, 95 % CI 1.017–1.022; contacts: RR 1.037, 95 % CI 1.030–1.044). Neuroticism and depression had the strongest influence on the associations. After adjustment for these factors, the associations between MUPS and HCU weakened, but remained significant (services: RR 1.011, 95 % CI 1.008–1.014; contacts: RR 1.023, 95 % CI 1.015–1.032).

Conclusions

Our results show that MUPS were positively associated with HCU over 2 years, even after adjusting for depressive and anxiety disorders and personality traits.

Illness perceptions of people with long-term conditions are associated with frequent use of the emergency department independent of mental illness and somatic symptom burden

OBJECTIVE

To determine whether illness perceptions of patients with long-term conditions (LTCs) are associated with urgent healthcare use and whether this association is independent from mental illness and somatic symptom burden.

METHODS

Illness perceptions (B-IPQ) and somatic symptom severity (PHQ-15) were assessed in 304 patients with diabetes, rheumatological disorders and COPD attending an Accident and Emergency Department (AED) in Greece over a one year period. The presence of mental illness was determined by the Mini International Neuropsychiatric Interview. A Generalized Linear Model (Negative Binomial) regression was used to determine the associations of illness perceptions with AED use after adjusting for mental illness, somatic symptom severity, disease parameters and demographics.

RESULTS

Eighty-six patients (28.3%) reported at least one visit to the AED during the previous year and 75 (24.7%) twice or more. 124 patients (40.8%) had some form of mental disorder with 85 (28.0%) meeting criteria for major depressive disorder. The degree to which the patients had an understanding of their illness (illness comprehensibility) (p<0.01) along with younger age (p<0.05), additional comorbidities (p<0.05) and greater somatic symptom burden (p<0.001) was strongly associated with AED use; AED visits were expected to be reduced by 9.1% for each unit increase in illness comprehensibility.

CONCLUSIONS

The way people perceive their illness influences urgent healthcare seeking behavior independent of somatic symptom burden. This finding indicates that information provision may prove effective in reducing urgent healthcare use and encourage the design of psycho-educational interventions targeting disease-related cognitions in an attempt to prevent unnecessary healthcare utilization.

Characterizing the vulnerability of frequent emergency department users by applying a conceptual framework: a controlled, cross-sectional study

BACKGROUND

Frequent emergency department (ED) users meet several of the criteria of vulnerability, but this needs to be further examined taking into consideration all vulnerability's different dimensions. This study aimed to characterize frequent ED users and to define risk factors of frequent ED use within a universal health care coverage system, applying a conceptual framework of vulnerability.

METHODS

A controlled, cross-sectional study comparing frequent ED users to a control group of non-frequent users was conducted at the Lausanne University Hospital, Switzerland. Frequent users were defined as patients with five or more visits to the ED in the previous 12 months. The two groups were compared using validated scales for each one of the five dimensions of an innovative conceptual framework: socio-demographic characteristics; somatic, mental, and risk-behavior indicators; and use of health care services. Independent t-tests, Wilcoxon rank-sum tests, Pearson's Chi-squared test and Fisher's exact test were used for the comparison. To examine the -related to vulnerability- risk factors for being a frequent ED user, univariate and multivariate logistic regression models were used.

RESULTS

We compared 226 frequent users and 173 controls. Frequent users had more vulnerabilities in all five dimensions of the conceptual framework. They were younger, and more often immigrants from low/middle-income countries or unemployed, had more somatic and psychiatric comorbidities, were more often tobacco users, and had more primary care physician (PCP) visits. The most significant frequent ED use risk factors were a history of more than three hospital admissions in the previous 12 months (adj OR:23.2, 95%CI = 9.1-59.2), the absence of a PCP (adj OR:8.4, 95%CI = 2.1-32.7), living less than 5 km from an ED (adj OR:4.4, 95%CI = 2.1-9.0), and household income lower than USD 2,800/month (adj OR:4.3, 95%CI = 2.0-9.2).

CONCLUSIONS

Frequent ED users within a universal health coverage system form a highly vulnerable population, when taking into account all five dimensions of a conceptual framework of vulnerability. The predictive factors identified could be useful in the early detection of future frequent users, in order to address their specific needs and decrease vulnerability, a key priority for health care policy makers. Application of the conceptual framework in future research is warranted.

Screening of mental health and substance users in frequent users of a general Swiss emergency department

Background

The objectives of this study were to determine the proportions of psychiatric and substance use disorders suffered by emergency departments’ (EDs’) frequent users compared to the mainstream ED population, to evaluate how effectively these disorders were diagnosed in both groups of patients by ED physicians, and to determine if these disorders were predictive of a frequent use of ED services.

Methods

This study is a cross-sectional study with concurrent and retrospective data collection. Between November 2009 and June 2010, patients’ mental health and substance use disorders were identified prospectively in face-to-face research interviews using a screening questionnaire (i.e. researcher screening). These data were compared to the data obtained from a retrospective medical chart review performed in August 2011, searching for mental health and substance use disorders diagnosed by ED physicians and recorded in the patients’ ED medical files (i.e. ED physician diagnosis). The sample consisted of 399 eligible adult patients (≥18 years old) admitted to the urban, general ED of a University Hospital. Among them, 389 patients completed the researcher screening. Two hundred and twenty frequent users defined by >4 ED visits in the previous twelve months were included and compared to 169 patients with ≤4 ED visits in the same period (control group).

Results

Researcher screening showed that ED frequent users were more likely than members of the control group to have an anxiety, depressive disorder, post-traumatic stress disorder (PTSD), or suffer from alcohol, illicit drug abuse/addiction. Reviewing the ED physician diagnosis, we found that the proportions of mental health and substance use disorders diagnosed by ED physicians were low both among ED frequent users and in the control group. Using multiple logistic regression analyses to predict frequent ED use, we found that ED patients who screened positive for psychiatric disorders only and those who screened positive for both psychiatric and substance use disorders were more likely to be ED frequent users compared to ED patients with no disorder.

Conclusions

This study found high proportions of screened mental health and/or substance use disorders in ED frequent users, but it showed low rates of detection of such disorders in day-to-day ED activities which can be a cause for concern. Active screening for these disorders in this population, followed by an intervention and/or a referral for treatment by a case-management team may constitute a relevant intervention for integration into a general ED setting.

Mortality, admission rates and outpatient use among frequent users of emergency departments: a systematic review

OBJECTIVE

This systematic review examines whether frequent emergency department (ED) users experience higher mortality, hospital admissions and outpatient visits than non-frequent ED users.

DESIGN

We published an a priori study protocol in PROSPERO. Our search strategy combined terms for 'frequent users' and 'emergency department'. At least two independent reviewers screened, selected, assessed quality and extracted data. Third-party adjudication resolved conflicts. Results were synthesised based on median effect sizes.

DATA SOURCES

We searched seven electronic databases with no limits and performed an extensive grey literature search.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

We included observational analytical studies that focused on adult patients, had a comparison group of non-frequent ED users and reported deaths, admissions and/or outpatient outcomes.

RESULTS

The search strategy identified 4004 citations; 374 were screened by full text and 31 cohort and cross-sectional studies were included. Authors used many different definitions to describe frequent users; the overall quality of the included studies was moderate. Across seven studies examining mortality, frequent users had a median 2.2-fold increased odds of mortality compared with non-frequent users. Twenty-eight studies assessing hospital admissions found a median increased odds of admissions per visit at 1.16 and of admissions per patient at 2.58. Ten studies reported outpatient visits with a median 2.65-fold increased risk of having at least one outpatient encounter post-ED visit.

CONCLUSIONS

Frequent ED users appear to experience higher mortality, hospital admissions and outpatient visits compared with non-frequent users, and may benefit from targeted interventions. Standardised definitions to facilitate comparable research are urgently needed.

Inpatient hospital costs and length of stay for the treatment of affective and somatoform disorders - evidence from Germany

INTRODUCTION

Diagnosis related costs analyses are the subject of science and research and are of great relevance and importance for decision makers in the hospital and for funding bodies, but also for international health policy. Up to now, standardized costs analyses with valid costs data have not been available for inpatient care of patients with affective and somatoform disorders.

BACKGROUND

This clinical picture presents a major challenge for the provision of outpatient and inpatient care. An interdisciplinary approach in an inpatient setting can be beneficial for already "chronified" patients with severe forms of progression. Because of its structural and procedural demands, this type of care is associated with a greater expenditure of resources.

METHODS

Costs data from the years 2008 to 2012 were analyzed for a total of 17,424 hospitalized patients in more than 200 different hospitals in Germany. The study compared the costs of treating patients with the main diagnosis affective and somatoform disorders using standardized interdisciplinary therapy, with the costs of conventional therapy.

RESULTS

Interdisciplinary patient care is characterized by a high proportion of the costs derived from the structural and procedural implementation and the medical and nursing care. For interdisciplinary therapy with a mean period of hospitalization of 15.2 days, over 60% of the total costs were incurred by the personnel and material costs of the medical and non-medical infrastructure. The outlay is considerably greater than would be incurred by a conventional therapeutic approach without interdisciplinary therapy.

DISCUSSION AND CONCLUSION

For the first time, detailed diagnosis-related costs data are published which were generated by consistent, standardized cost unit accounting. An interdisciplinary, holistic approach to the clinical picture results in a significant increase in costs for the hospitals.

Effectiveness of quality improvement strategies for coordination of care to reduce use of health care services: a systematic review and meta-analysis

BACKGROUND

Frequent users of health care services are a relatively small group of patients who account for a disproportionately large amount of health care utilization. We conducted a meta-analysis of the effectiveness of interventions to improve the coordination of care to reduce health care utilization in this patient group.

METHODS

We searched MEDLINE, Embase and the Cochrane Library from inception until May 2014 for randomized clinical trials (RCTs) assessing quality improvement strategies for the coordination of care of frequent users of the health care system. Articles were screened, and data abstracted and appraised for quality by 2 reviewers, independently. Random effects meta-analyses were conducted.

RESULTS

We identified 36 RCTs and 14 companion reports (total 7494 patients). Significantly fewer patients in the intervention group than in the control group were admitted to hospital (relative risk [RR] 0.81, 95% confidence interval [CI] 0.72-0.91). In subgroup analyses, a similar effect was observed among patients with chronic medical conditions other than mental illness, but not among patients with mental illness. In addition, significantly fewer patients 65 years and older in the intervention group than in the control group visited emergency departments (RR 0.69, 95% CI 0.54-0.89).

INTERPRETATION

We found that quality improvement strategies for coordination of care reduced hospital admissions among patients with chronic conditions other than mental illness and reduced emergency department visits among older patients. Our results may help clinicians and policy-makers reduce utilization through the use of strategies that target the system (team changes, case management) and the patient (promotion of self-management).

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.

[Would the Screening of Common Mental Disorders in Primary-Care Health Services Hyper-Frequent Patients Be Useful?]

Hyper-frequentation in health services is a problem for patients, their families and the institutions. This study is aimed at determining the frequency and characteristics of common mental disorders in hyper-frequent patients showing vague symptoms and signs at a primary healthcare service during the year 2007 in the city of Cali (Colombia).

METHODOLOGY

Cross sectional. The most frequent mental disorders in hyper-frequent patients were detected through a telephone interview which included several modules of the PRIME MD instrument.

RESULTS

In general, healthcare service hyper-frequenters are working women, 38,7-year old in average. Basically, the consultation is due to cephalalgia but they also exhibit a high prevalence of common mental disorders (somatization, depression and anxiety) not easily diagnosed by physicians in primary care. Expenses for additional health activities generated by these patients are attributed basically to medical consultation and required procedures.

CONCLUSION

Considering hyper-frequenters in health care services as a risk group in terms of common mental disorders involves screening as an efficient strategy to prevent abuse in service use and to improve satisfaction with the attention received.

An observational study of emergency department utilization among enrollees of Minnesota Health Care Programs: financial and non-financial barriers have different associations

BACKGROUND

Emergency department (ED) use is costly, and especially frequent among publicly insured populations in the US, who also disproportionately encounter financial (cost/coverage-related) and non-financial/practical barriers to care. The present study examines the distinct associations financial and non-financial barriers to care have with patterns of ED use among a publicly insured population.

METHODS

This observational study uses linked administrative-survey data for enrollees of Minnesota Health Care Programs to examine patterns in ED use-specifically, enrollee self-report of the ED as usual source of care, and past-year count of 0, 1, or 2+ ED visits from administrative data. Main independent variables included a count of seven enrollee-reported financial concerns about healthcare costs and coverage, and a count of seven enrollee-reported non-financial, practical barriers to access (e.g., limited office hours, problems with childcare). Covariates included health, health care, and demographic measures.

RESULTS

In multivariate regression models, only financial concerns were positively associated with reporting ED as usual source of care, but only non-financial barriers were significantly associated with greater ED visits. Regression-adjusted values indicated notable differences in ED visits by number of non-financial barriers: zero non-financial barriers meant an adjusted 78% chance of having zero ED visits (95% C.I.: 70.5%-85.5%), 15.9% chance of 1(95% C.I.: 10.4%-21.3%), and 6.2% chance (95% C.I.: 3.5%-8.8%) of 2+ visits, whereas having all seven non-financial barriers meant a 48.2% adjusted chance of zero visits (95% C.I.: 30.9%-65.6%), 31.8% chance of 1 visit (95% C.I.: 24.2%-39.5%), and 20% chance (95% C.I.: 8.4%-31.6%) of 2+ visits.

CONCLUSIONS

Financial barriers were associated with identifying the ED as one's usual source of care but non-financial barriers were associated with actual ED visits. Outreach/literacy efforts may help reduce reliance on/perception of ED as usual source of care, whereas improved targeting/availability of covered services may help curb frequent actual visits, among publicly insured individuals.

A preliminary study of psychiatric, familial, and medical characteristics of high-utilizing sickle cell disease patients

OBJECTIVES

To identify demographic, medical, and psychosocial characteristics that distinguished sickle cell disease (SCD) patients who were frequent utilizers of urgent or emergent care resources from low-utilizing patients.

METHODS

Patients at a large urban comprehensive SCD treatment center were recruited from clinic or during urgent care visits. Participants who were high utilizers, defined as having >4 acute or emergency care visits in the prior 12 months, were compared with patients with more typical utilization patterns on lifetime complications of SCD, family background, psychiatric history, occupational function, coping, depressive symptoms, and personality.

RESULTS

High utilizers were nearly a decade younger on average; despite this they had a similar lifetime history of SCD complications. High-utilizing patients' parents seemed to have greater educational achievement overall. High utilizers reported a nearly 3-fold greater prevalence of psychiatric illness in family members than low utilizers. On other measures, including coping strategies, social support, and personality, the 2 groups were comparable.

DISCUSSION

The study strengthens emerging evidence that disease severity, familial factors related to greater parental education, and psychiatric illness are important factors in high care utilization in patients with SCD.

Struggling on my own: a cognitive perspective on frequent attenders' conception of life and their interaction with the healthcare system

Different studies reveal that a large percentage of people frequently attending healthcare not only suffer from diffuse somatic symptoms but also from psychological distress and difficulties in dealing with everyday life. Even though they are not always diagnosed with psychiatric disease, questions arise about their mental health. The study aims at describing frequent attenders' conceptions of life, and as a result their health, from a cognitive perspective. A qualitative content analysis of in-depth interviews was carried out with nine service users in primary healthcare. The findings reveal that participants experience themselves as inadequate and as being a burden for others, by whom they experience rejection, in different ways. In order to take part in community with others the person develops compensatory strategies that aim at concealing their inadequacies, thus also preventing them from sharing their suffering with others. The consequence is that the persons become even more alienated as they start to relate to others through a façade and furthermore are unable to either improve their health or obtain adequate care. It can be concluded that these patients need to be taken seriously in order to prevent further psychological suffering.

Maternal somatic symptoms, psychosocial correlates, and subsequent pediatric emergency department use

BACKGROUND

Somatization is associated with increased health care use in adults. Whether mothers with somatic symptoms use more health care resources for their children has not been investigated.

OBJECTIVE

This study aimed to explore the association of maternal somatic symptoms and emergency department (ED) use.

DESIGN/METHODS

Mothers from a cohort of 319 mother-child dyads were screened for somatic symptoms using the Patient Health Questionnaire 15. Dyads were followed up for 3 years after the initial ED visit to record ED use. The outcome variable was ED use (lower ED use, 0-3 visits, higher ED use, 4+ visits). The primary independent variable was somatization, with a dichotomous variable analyzing the Patient Health Questionnaire 15 symptom count of less than 7 symptoms (lower somatization) and 7 or more symptoms (higher somatization [HISOM]). Secondary independent variables included demographic data, maternal major depression, and maternal difficulty in taking care of the child or themselves. Statistical analysis included bivariate and multivariate analyses.

RESULTS

Mothers with HISOM symptoms did not demonstrate an increased use of the ED in bivariate analysis. Higher somatization mothers did show an increased (1) endorsement of maternal major depression symptoms and (2) maternal perception of difficulty in taking care of the child and themselves. When adjusted for these and other covariates, HISOM mothers were more likely to be in the higher ED use group (1.83; 95% confidence interval, 0.99-3.38) P = 0.055).

CONCLUSIONS

Mothers with higher somatic symptom loads were more likely to screen positive for depression and to report difficulty caring for their child and for themselves. A trend toward higher use of the pediatric ED warrants further study.

Occult psychosocial impairment in a pediatric emergency department population

OBJECTIVES

We compared the degree of psychosocial impairment in patients seen in the emergency department (ED) for acute complaints with that of patients presenting with chronic complaints using the Youth Pediatric Symptom Checklist (PSC-Y). Our hypothesis was that patients with multiple visits for chronic complaints (>3 health care visits for the chief complaint during the previous 12 months) would be more likely than patients with acute complaints to test positive for psychosocial issues.

METHODS

The PSC-Y was administered to patients aged 8 to 18 years presenting to a pediatric ED for nonpsychiatric complaints. We compared proportions of patients testing positive for psychosocial impairment on the PSC-Y or any of its subscales.

RESULTS

In the 442 patients enrolled, 25% endorsed chronic symptoms. There was a significant difference in the proportion of patients scoring positive for psychosocial impairment between the acute and chronic group (13.8% vs 18.1%, P = 0.002) as well as in the proportion of patients testing positive for attentional issues (6.4% vs 13.9%, P = 0.02). Each subscale was analyzed independently, and there were no statistically significant intergroup differences in internalizing symptoms (anxiety, depression) or externalizing symptoms (conduct issues).

CONCLUSIONS

Patients with recurrent presentations for the same complaint had significantly higher rates of overall psychosocial impairment. Regardless of complaint acuity, impairment rates were notable, with 20% of patients reporting internalizing symptoms, such as anxiety and depression. Psychosocial issues should be considered in all pediatric ED patients but particularly those with greater than 3 health care visits for the same presenting complaint.

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.

Does depression predict the use of urgent and unscheduled care by people with long term conditions? A systematic review with meta-analysis

BACKGROUND

Factors that drive the use of urgent healthcare among people with chronic physical illness (i.e. long term conditions-LTCs) are poorly understood. We conducted a systematic review with meta analysis to examine the strength of association between depression and subsequent use of urgent healthcare among people with LTCs.

METHODS

Electronic searches of MEDLINE, EMBASE, PSYCINFO, CINAHL, the British Nursing Library and the Cochrane Library 2011 were conducted, supplemented by hand-searching bibliographies, citation tracing eligible studies and asking experts about relevant studies. Studies were eligible for inclusion if they: i)used prospective cohort design, ii)included patients with diabetes, asthma, chronic obstructive pulmonary disease or coronary heart disease, iii)used a standardised measure of depression, and iv)assessed urgent healthcare utilisation prospectively. Data on the subjects recruited, methods used and the association between depression and subsequent urgent healthcare utilisation were extracted from eligible studies. Odds ratios (ORs) were calculated for each study and pooled using random effects models.

RESULTS

16 independent studies were identified. Pooled effects indicated that depression was associated with a 49% increase in the odds of urgent healthcare utilisation (OR=1.49, p<.0005). This effect was not significantly affected by publication bias or inclusion of studies of low quality. Effects were much smaller and non-significant among the 3 studies that controlled for other covariates, including severity of illness (OR=1.13, p=.31).

CONCLUSIONS

Depression was associated with increased urgent healthcare use, but not in the minority of studies that controlled for other covariates. This possibly suggests confounding, but the severity measures may themselves have been influenced by depression.

Alcohol diagnoses among older Tennessee Medicare beneficiaries: race and gender differences

BACKGROUND

These analyses bolster a sparse body of research focusing on the rate of alcohol disorders among older adults, particularly race and gender subgroups.

METHODS

We based the study on cross-sectional data from all Medicare billed physician/patient encounters. Analyses of these data included cross-tabulations, difference of means tests, and difference of proportions tests, logistic regression and multinomial logistic regression. These analyses were based Medicare billing records from physician/patient encounters in Tennessee. Data included Tennessee Medicare billings beneficiaries enrolled in Medicare Part B, who saw a physician at least once in 2000. Patients with billings containing ICD-9 codes: 303 (alcohol abuse), 305 (alcohol dependence), 291 (alcohol psychosis), or 571.1-571.3 (alcohol-related liver disease including cirrhosis of the liver) as to primary diagnosis were considered alcohol-disordered.

RESULTS

Analyses reveal the overall rate of alcohol disorders, subgroup variation in rates and differences in pattern of specific disorders. Merely 0.04% of Tennessee Medicare beneficiaries were diagnosed with any type of alcoholism, a rate much lower than those reported in previous studies. Rates of alcohol disorders varied across groups, with significantly higher rates for Black men. The type alcohol disorder also varied across groups.

CONCLUSIONS

Many encounters with the medical system result in missed opportunities to identify and treat alcohol disorders, a significant risk factor among older adults. Alcoholism both triggers and exacerbates many chronic conditions among older adults. The earlier in the disease trajectory the more of these conditions could be prevented or more efficiently managed, resulting in substantial savings in health care costs.

Healthcare costs incurred by patients repeatedly referred to secondary medical care with medically unexplained symptoms: a cost of illness study

BACKGROUND

Some patients are repeatedly referred from primary to secondary care with medically unexplained symptoms (MUS). We aimed to estimate the healthcare costs incurred by such referrals and to compare them with those incurred by other referred patients from the same defined primary care sample.

METHODS

Using a referral database and case note review, all adult patients aged less than 65 years, who had been referred to specialist medical services from one of five UK National Health Service primary care practices in a five-year period, were identified. They were placed in one of three groups: (i) repeatedly referred with MUS (N=276); (ii) infrequently referred (IRS, N=221), (iii) repeatedly referred with medically explained symptoms (N=230). Secondary care activities for each group (inpatient days, outpatient appointments, emergency department attendances and investigations) were identified from primary care records. The associated costs were allocated using summary data and the costs for each group compared.

RESULTS

Patients who had been repeatedly referred with MUS had higher mean inpatient, outpatient and emergency department costs than those infrequently referred (£3,539, 95% CI 1458 to 5621, £778 CI 705 to 852 and £99, CI 74 to 123 respectively. The mean overall costs were similar to those of patients who had been repeatedly referred with medically explained symptoms.

CONCLUSIONS

The repeated referral of patients with MUS to secondary medical care incurs substantial healthcare costs. An alternative form of management that reduces such referrals offers potential cost savings.

Frequent emergency attenders: is there a better way?

BACKGROUND

Understanding the reasons for frequent re-attendances will assist in developing solutions to hospital overcrowding. This study aimed to identify the factors associated with frequent re-attendances in a regional hospital thereby highlighting possible solutions to the problem.

METHODS

A retrospective analysis was performed on emergency department data from 2008. Frequent re-attenders were defined as those with four or more presentations in a year. Clinical, service usage and demographic patient characteristics were examined for their influence on re-presentations using multivariate analysis. RESULTS; A total of 8% of the total patients presenting to emergency re-attended four or more times in the year. Frequent re-attenders were older, presented with an unplanned returned visit and had a diagnosis of neurosis, chronic obstructive pulmonary disease (COPD), convulsions, dyspnoea or repeat prescriptions, follow-up examinations or dressings and sutures and less likely to present in summer. Frequent re-attendances were unrelated to sex, time of presentation or country of birth.

CONCLUSIONS

Diversion of patients with minor conditions to alternative services; referral of COPD patients to follow-up respiratory services and patients with neurosis to community mental health services would reduce emergency utilisation. Improving access to and resourcing of alternative non-hospital services should be investigated to reduce emergency overcrowding.

Predictors of repeated emergency department visits among persons treated for addiction

BACKGROUND/AIMS

To determine whether frequent emergency department (ED) users who enter specialized treatment programs for alcohol and/or drug problems have any characteristics that predict their future ED use.

METHODS

Adult patients (783 alcohol users, 405 illicit drug users) were interviewed. Data from the medical database on utilization of ED and the emergency departments' specific units for addictive diseases (EDAD) 12 months before and 12 months after the interview were linked with patient characteristics in logistic regression models.

RESULTS

Among alcohol users, prior ED/EDAD visits predicted repeat future visits to these sites (OR 11.6; 95% CI 6.5-20.5). Prior inpatient hospital care with addiction diagnosis was a predictor of future multiple visits to the EDAD only (OR 3.1; 95% CI 1.5-6.5). Among drug users, predictors of future ED/EDAD visits were use of heroin (OR 2.7; 95% CI 1.4-5.4) and prior ED/EDAD visits (OR 27.3; 95% CI 12.7-58.4). Drug users' EDAD utilization was also predicted by inpatient hospital care with addiction diagnosis.

CONCLUSION

The strongest predictive factors of visiting ED repeatedly were previous repeat emergency care use and hospitalization with addiction diagnosis. Entering regular addiction treatment does not appear to alter the pattern of ED utilization.

Current practices for mental health follow-up after psychiatric emergency department/psychiatric emergency service visits: a national survey of academic emergency departments

OBJECTIVE

The objective was to describe continuity of care approaches for psychiatric emergencies in the emergency department.

METHODS

A national survey of all 138 academic emergency departments in the United States was conducted.

RESULTS

Most emergency physicians (81%) had no systematic method for identifying psychiatric emergency patients with high recidivism. In order to promote outpatient care, sites commonly reported using intensive interventions, including scheduling outpatient appointments prior to discharge (72%) and in-house case management (64%).

CONCLUSION

While systematic identification of repeat psychiatric emergency patients was uncommon, emergency departments reported using a variety of fairly intensive strategies to promote continuity of care with outpatient mental health services.

Mental disorders among frequent attenders in primary care: a comparison with routine attenders

Frequent attenders account for a large proportion of primary care (PC) contacts, referrals, and prescriptions. Psychosocial and emotional distress is related to the high use of health services. Few studies have focused on the association between mental disorders assessed using structured interviews and frequent use of PC services.The aim of this study was to determine the factors associated with frequent attendance at primary healthcare units, focusing specifically on mental disorders. A two-phase screening epidemiological study comparing frequent attenders and routine attenders in five primary health care units was designed. Three hundred eighteen frequent attenders and 203 patients who attended the same units on a routine basis were compared. Sociodemographic and clinical data were obtained from statistical records and medical charts. Patients with a total score equal or higher than 7 points on the General Health Questionnaire-28 (GHQ-28) were interviewed using the Schedules for Clinical Assessment in Neuropsychiatry. All the scores obtained on the GHQ were statistically different in the two populations. Frequency of mental disorders also differed significantly between both groups, with somatoform and affective disorders being the most prevalent ICD-10 categories among frequent attenders. The presence of depressive disorders and somatoform disorders is the most powerful predictive factor for frequent attendance. High comorbidity was found among frequent attenders with somatoform disorder. Frequent attendance at primary healthcare units is associated with depressive and somatoform disorders. Psychiatric comorbidity could be a confounder, particularly because affective and somatoform disorders often overlap in PC patients.

Health care utilization and poor reassurance: potential predictors of somatoform disorders

OBJECTIVE

Somatoform disorders are common conditions, but the current diagnostic criteria are considered to be unreliable, based largely on medically unexplained symptoms. DSM-5 is considering other possible characteristics of somatizers including high utilization, dissatisfaction with care, and poor response to reassurance. This paper reviews the available literature for evidence to support these criteria, and evaluates if distinctive aspects of these characteristics exist in somatizers.

METHODS

The Pubmed database was searched combining terms such as “somatoform disorder” with “reassurance,” “satisfaction,” and “utilization.” Articles were individually inspected.

RESULTS

Many studies report a deficit in long-term response to reassurance in somatizers; there was some evidence that patients respond initially to reassurance, followed by return of anxiety, leading to further reassurance seeking. There was insufficient evidence to support poor satisfaction with care as a characteristic of somatizers. While there is no standard criterion for high utilization, regardless of definition, evidence was found to support over-utilization, particularly in outpatient visits. However, no unique pattern of utilization was found that could identify somatizers within a broader group of high utilizers.

CONCLUSIONS

This review revealed evidence of over-utilization in many areas of healthcare, as well as poor long term response to reassurance in somatizers. Dissatisfaction with care, though, was not a consistent finding. It is difficult to study alternative diagnostic criteria for somatoform patients when the current criteria rest on so many problematic assumptions. Future research should attempt to validate criteria empirically in patient groups, with selection not based on medically unexplained symptoms.

Association of mental health with health care use and cost: a population study

OBJECTIVE

To compare the health costs of groups with and without psychiatric diagnoses (PDs) using 9 years of physician billing data.

METHODS

A dataset containing registration data for all patients receiving public mental health service was constructed and subsequently matched, on age and sex, in a final patient to comparison patient ratio of 1:8, with health care users who did not receive treatment in the mental health system. Three groups emerged: a patient PD group-patients with psychiatric disorders treated in public mental health care (n = 76 677); a comparison patient PD group-comparison patients with PDs treated in physicians only (n = 277 627); and a patient- comparison patient non-PD group-patients (treated in specialized publicly funded care or by their physician) without PDs (n = 329 177). Examining over 42 million billing records for all of these patients, we compared the average number of visits and the average health only (nonpsychiatric) billing cost per each patient during the 9-year study period across the groups.

RESULTS

Among all health care users in the data, the health costs (Total Costs - Mental Health Costs) were greater on average for the patients with PD group ($3437) and the comparison patient PD group ($3265), compared with patient-comparison patient non-PD group ($1345). Forty-six percent of the comparison sample had a PD.

CONCLUSIONS

Having a mental health problem is related to greater health-related expenditures. This has important policy implications on how mental health resources are constructed and rationed within the health care system.
