Appropriateness of emergency department visits in a Portuguese university hospital

Impact of the COVID-19 Pandemic on Inappropriate Use of the Emergency Department

Background: Inappropriate use of the emergency department (IEDU)-consisting of the unnecessary use of the resource by patients with no clinical need-is one of the leading causes of the loss of efficiency of the health system. Specific contexts modify routine clinical practice and usage patterns. This study aims to analyse the influence of COVID-19 on the IEDU and its causes. Methods: A retrospective, cross-sectional study conducted in the emergency department of a high-complexity hospital. The Hospital Emergency Suitability Protocol (HESP) was used to measure the prevalence of IEDU and its causes, comparing three pairs of periods: (1) March 2019 and 2020; (2) June 2019 and 2020; and (3) September 2019 and 2020. A bivariate analysis and multivariate logistic regression models, adjusted for confounding variables, were utilized. Results: In total, 822 emergency visits were included (137 per period). A total prevalence of IEDU of 14.1% was found. There was a significant decrease in IEDU in March 2020 (OR: 0.03), with a prevalence of 0.8%. No differences were found in the other periods. A mistrust in primary care was the leading cause of IEDU (65.1%). Conclusions: The impact of COVID-19 reduced the frequency of IEDU during the period of more significant population restrictions, with IEDU returning to previous levels in subsequent months. Targeted actions in the field of population education and an improvement in primary care are positioned as strategies that could mitigate its impact.

Calling an ambulance for non-emergency medical situations: Results of a cross-sectional online survey from an Australian nationally representative sample

OBJECTIVE

To investigate the Australian general public's perception of appropriate medical scenarios that warrants a call to an emergency ambulance.

METHODS

An online survey asked participants to identify the likely medical treatment pathway they would take for 17 hypothetical medical scenarios. The number and type of non-emergency scenarios (n = 8) participants incorrectly suggested were appropriate to place a call for an emergency ambulance were calculated. Participants included Australian residents (aged >18 years) who had never worked as an Australian registered medical doctor, nurse or paramedic.

RESULTS

From a sample of 5264 participants, 40% suggested calling an emergency ambulance for a woman in routine labour was appropriate. Other medical scenarios which were most suggested by participants to warrant an emergency ambulance call was 'Lego in ear canal' (11%), 'Older person bruising' (8%) and 'Flu' (7%). Women, people aged 56+ years, those without a university qualification, with lower household income and with lower emotional wellbeing were more likely to suggest calling an emergency ambulance was appropriate for non-emergency scenarios.

CONCLUSIONS

Although emergency healthcare system (EHS) capacity not increasing at the same rate as demand is the biggest contributor to EHS burden, non-urgent medical situations for which other low-acuity healthcare pathways may be appropriate does play a small role in adding to the overburdening of the EHS. This present study outlines a series of complaints and demographic characteristics that would benefit from targeted educational interventions that may aid in alleviating ambulance service attendances to low-acuity callouts.

Patterns of Emergency Department visits for acute and chronic diseases during the two pandemic waves in Italy

BACKGROUND

Evidence is lacking about the impact of subsequent COVID-19 pandemic waves on Emergency Departments (ED). We analyzed the differences in patterns of ED visits in Italy during the two pandemic waves, focusing on changes in accesses for acute and chronic diseases.

METHODS

We conducted a retrospective study using data from a metropolitan area in northern Italy that includes twelve ED. We analyzed weekly trends in non-COVID-19 ED visits during the first (FW) and second wave (SW) of the pandemic. Incidence rate ratios (IRRs) of triage codes, patient destination, and cause-specific ED visits in the FW and SW of the year 2020 vs. 2019 were estimated using Poisson regression models.

MAIN FINDINGS

We found a significant decrease of ED visits by triage code, which was more marked for low priority codes and during the FW. We found an increased share of hospitalizations compared to home discharges both in the FW and in the SW. ED visits for acute and chronic conditions decreased during the FW, ranging, from -70% for injuries (IRR = 0.2862, p < 0.001) to -50% and - 60% for ischemic heart disease and heart failure.

CONCLUSIONS

The two pandemic waves led to a selection of patients with higher and more urgent needs of acute hospital care. These findings should lead to investigate how to improve systems' capacity to manage changes in population needs.

Hunger pains? SNAP timing and emergency room visits

This project uses quasi-random assignment of SNAP receipt dates linked to Medicaid healthcare records to examine whether ER use is affected by the timing of benefits. We find an increase in ER usage at the end of the benefit month, but only among older recipients. The estimated effect is much larger when the end of the benefit cycle coincides with the end of the calendar month, which is when other transfer payments are also depleted. This suggests that within this older group, increased food insecurity leads to increased ER utilization. Further, we find that the share of ER visitors that received SNAP benefits on the day of their ER visit is 3.1% lower than in the SNAP population. This is consistent with benefit receipt altering household behaviors and routines (notably, we observe, by increasing shopping), which may crowd out healthcare utilization. This particular effect is present across all age groups, although the magnitude is smallest for children.

Factors associated with inappropriate use of emergency departments: findings from a cross-sectional national study in France

BACKGROUND

Inappropriate visits to emergency departments (EDs) could represent from 20% to 40% of all visits. Inappropriate use is a burden on healthcare costs and increases the risk of ED overcrowding. The aim of this study was to explore socioeconomic and geographical determinants of inappropriate ED use in France.

METHOD

The French Emergency Survey was a nationwide cross-sectional survey conducted on June 11 2013, simultaneously in all EDs in France and covered characteristics of patients, EDs and counties. The survey included 48 711 patient questionnaires and 734 ED questionnaires. We focused on adult patients (≥15 years old). The appropriateness of the ED visit was assessed by three measures: caring physician appreciation of appropriateness (numeric scale), caring physician appreciation of whether or not the patient could have been managed by a general practitioner and ED resource utilisation. Descriptive statistics and multilevel logistic regression were used to examine determinants of inappropriate ED use, estimating adjusted ORs and 95% CIs.

RESULTS

Among the 29 407 patients in our sample, depending on the measuring method, 13.5% to 27.4% ED visits were considered inappropriate. Regardless of the measure method used, likelihood of inappropriate use decreased with older age and distance from home to the ED >10 km. Not having a private supplementary health insurance, having universal supplementary health coverage and symptoms being several days old increased the likelihood of inappropriate use. Likelihood of inappropriate use was not associated with county medical density.

CONCLUSION

Inappropriate ED use appeared associated with socioeconomic vulnerability (such as not having supplementary health coverage or having universal coverage) but not with geographical characteristics. It makes us question the appropriateness of the concept of inappropriate ED use as it does not consider the distress experienced by the patient, and segments of society seem to have few other choices to access healthcare than the ED.

Potential of a nurse telephone triage line to direct elderly to appropriate health care settings

AIM

To explore the potential of a nurse health triage telephone line to advise and guide elderly users' decisions regarding the appropriate health care setting and self-care.

BACKGROUND

Ageing is a concern in many countries and poses challenges to health care services. Triage and advice lines can play an important role for the (re)organisation of health care delivery. Discussion has been focused on the capacity of these lines to reduce inappropriate demand for acute and emergency departments.

METHODS

Cross-sectional descriptive analysis.

RESULTS

Nurses directed elders to a health care service both by downgrading their initial intentions (concurring to the most common objective) and by upgrading them (e.g., directing elders that intended to stay at home to acute and emergency care). The intention to comply with the nurse's disposition was high.

CONCLUSIONS

The line helped to improve the appropriateness of acute and emergency care demand and to reduce the overall demand for care by elders. There is nonetheless space for improvement given the underuse of the line by elders.

IMPLICATIONS FOR NURSING MANAGEMENT

Health telephone-based triage and advice should be promoted to increase the match between the needs of elderly patients and health resources, thus improving health equity.

Sense-making strategies and help-seeking behaviours associated with urgent care services: a mixed-methods study

Background

Policy has been focused on reducing unnecessary emergency department attendances by providing more responsive urgent care services and guiding patients to ‘the right place’. The variety of services has created a complex urgent care landscape for people to access and navigate.

Objectives

To describe how the public, providers and policy-makers define and make sense of urgent care; to explain how sense-making influences patients’ strategies and choices; to analyse patient ‘work’ in understanding, navigating and choosing urgent care; to explain urgent care utilisation; and to identify potentially modifiable factors in decision-making.

Design

Mixed-methods sequential design.

Setting

Four counties in southern England coterminous with a NHS 111 provider area.

Methods

A literature review of policy and research combined with citizens’ panels and serial qualitative interviews. Four citizens’ panels were conducted with the public, health-care professionals, commissioners and managers (n = 41). Three populations were sampled for interview: people aged ≥ 75 years, people aged 18–26 years and East European people. In total, 134 interviews were conducted. Analyses were integrated to develop a conceptual model of urgent care help-seeking.

Findings

The literature review identified some consensus between policy and provider perspectives regarding the physiological factors that feature in conceptualisations of urgent care. However, the terms ‘urgent’ and ‘emergency’ lack specificity or consistency in meaning. Boundaries between urgent and emergency care are ill-defined. We constructed a typology that distinguishes three types of work that take place at both the individual and social network levels in relation to urgent care sense-making and help-seeking.Illness workinvolves interpretation and decision-making about the meaning, severity and management of physical symptoms and psychological states, and the assessment and management of possible risks. Help-seeking was guided bymoral work: the legitimation and sanctioning done by service users.Navigation workconcerned choosing and accessing services and relied on prior knowledge of what was available, accessible and acceptable. From these empirical data, we developed a model of urgent care sense-making and help-seeking behaviour that emphasises that work informs the interaction between what we think and feel about illness and the need to seek care (sense-making) and action – the decisions we take and how we use urgent care (help-seeking).

Limitations

The sample population of our three groups may not have adequately reflected a diverse range of views and experiences. The study enabled us to capture people’s views and self-reported service use rather than their actual behaviour.

Conclusions

Much of the policy surrounding urgent and emergency care is predicated on the notion that ‘urgent’ sits neatly between emergency and routine; however, service users in particular struggle to distinguish urgent from emergency or routine care. Rather than focusing on individual sense-making, future work should attend to social and temporal contexts that have an impact on help-seeking (e.g. why people find it more difficult to manage pain at night), and how different social networks shape service use.

Future work

A whole-systems approach considering integration across a wider network of partners is key to understanding the complex relationships between demand for and access to urgent care.

Overestimation of health urgency as a cause for emergency services inappropriate use: Insights from an exploratory economics experiment in Portugal

Increasing visits to emergency departments add strain to public healthcare systems. The misperception of symptoms' severity can partly explain inappropriate use of hospitals' emergency departments by non-urgent patients. This paper focuses on the misperception of symptoms' severity as a cause for the inappropriate use of emergency departments. It explores the role that informing potential patients of the correct severity level can play in correcting this inefficiency. We implement in an incentivised manner an exploratory economic experiment to elicit the degree of severity of five sets of symptoms, corresponding to frequent causes of emergency department visits. The study was setup in Braga, Northern Portugal, recruiting voluntary participants through civic local organisations. We ask participants to indicate the more suitable health service, before and after revealing the true degree of severity. Results show that there is an overestimation of the degree of severity of some clinical profiles, and when confronted with the real severity, in only half of the cases are choices changed to other health services. Although exploratory, this study provides insights into the potential role of health education policies concerning symptoms' severity but it also highlights the limits of such policies. Furthermore, the use of economic experiments can provide meaningful insights for the design of policies addressing demand-side healthcare inefficiencies.

Non-urgent paediatric emergency department presentation: A systematic review

There has been an increase in the use of the emergency department (ED) for non-urgent presentations. The aim of this systematic review was to identify the proportion, criteria and predictors of non-urgent ED presentations in paediatric populations. A search of multiple databases was conducted for articles published from inception of the databases to 20 August 2018, which reported the proportion, criteria and predictors of non-urgent ED presentation in paediatric populations. Thirty-one articles met the inclusion criteria. The mean proportion of non-urgent paediatric ED presentations was 41.06 ± 15.16%. There appears to be a weak association between predisposing, enabling and needs factors and non-urgent ED use in paediatric populations. The findings of this review suggest that non-urgent ED use in paediatric populations is high. However, non-urgent ED use and the reasons for the visits in paediatric populations remain understudied.

A Multilevel Analysis of the determinants of emergency care visits by the elderly in France

BACKGROUND

Rising numbers of visits to emergency departments (EDs), especially amongst the elderly, is a source of pressure on hospitals and on the healthcare system. This study aims to establish the determinants of ED visits in France at a territorial level with a focus on the impact of ambulatory care organisation on ED visits by older adults aged 65 years and over.

METHODS

We use multilevel regressions to analyse how the organisation of healthcare provision at municipal and wider 'department' levels impacts ED utilisation by the elderly while controlling for the local demographic, socioeconomic and health context of the area in which patients live.

RESULTS

ED visits vary significantly by health context and economic level of municipalities. Controlling for demand-side factors, ED rates by the elderly are lower in areas where accessibility to primary care is high, measured as availability of primary care professionals, out-of-hours care and home visits in an area. Proximity (distance) and size of ED are drivers of ED use.

CONCLUSION

High rates of ED visits are partly linked to inadequate accessibility of health services provided in ambulatory settings. Redesigning ambulatory care at local level, in particular by improving accessibility and continuity of primary and social care services for older adults could reduce ED visits and, therefore, improve the efficient use of available healthcare resources.

Inadequate visits to the emergency department by pregnant women

Inadequate emergency visits, which could be resolved in primary care, are an unnecessary expense for the healthcare service. We did a review of all gynaecology and obstetrics emergency visits by pregnant or postpartum women during 2010 and 2011 in order to describe the adequacy of the visits by pregnant women to the emergency service. We defined three levels of adequacy: adequate, moderately adequate, and inadequate. One thousand seven hundred and forty-three visits to the emergency room of gynaecology and obstetrics were studied. These consultation motivations were adequate in 38.9%, moderately adequate in 46.7% and inadequate in 14.4%. This shows that the amount of inadequate and moderately adequate visits to the emergency department could be reduced by 61% by implementing different interventions, and also reducing health spending for emergencies. Impact statement What is already known on this subject: Visits to the emergency room constitute a basic pillar in the hospital structure, and it generates great health expense. Other authors have reported high rates of inadequacy of these visits to the emergency services. They find inadequate visits are associated with young age and female gender among other factors. What the results of this study add: Knowing the adequacy of the visits generated by pregnant young women is a starting point for implementing health policies that could reduce these inadequate visits and consequently health expenditure could be reduced. What the implications are of these findings for clinical practice and/or further research: These health policies could consequently reduce health expenditure.

Identification of appropriate and potentially avoidable emergency department referrals in a tertiary cancer care center

PURPOSE

Referrals to the Emergency Department can be distressing to patients with advanced cancer and may be a non-optimizing health care service. We aimed to describe the appropriateness and potential avoidability of Emergency Department referrals in a tertiary cancer care center where only physician referrals are allowed.

METHODS

We prospectively reviewed the electronic medical charts of patients consecutively checked into the Emergency Department in August 2015. The appropriateness of referrals was assessed using a nationally validated classification (Classification Clinique des Malades aux Urgences) and local criteria. Potentially avoidable referrals were assessed using international classifications (Institute for Healthcare Improvement State Action on Avoidable Rehospitalizations diagnostic tool according to Kosecoff's criteria) and local criteria.

RESULTS

We included 500 referrals related to 423 patients. The mean age was 59 years, and 74% of cancers were progressive. The referrals were appropriate in 61% of cases. They were deemed potentially avoidable "with a high likelihood" in 33.4% (CI95% [29.3-37.5]) of cases, potentially avoidable "with a moderate likelihood" in 14.4% (CI95% [11.3-17.5]) of cases, and "non-avoidable" in 52% (CI95% [47.6-56.4]) of cases. Opportunities to avoid referrals after an index stay involved this hospital stay or discharge process in 66 cases (28%), the follow-up period in 59 cases (25%), or both in 66 cases (28%).

CONCLUSIONS

Potentially avoidable ED referrals are common in patients with cancer. These potentially avoidable ED referrals underline the importance of several domains of care coordination.

Attributes and circumstances that induce inappropriate health services demand: a study of the health sector in Brazil

Background

The current economic and social context has required health systems to provide top quality services and to be efficient in controlling costs. An obstacle to achieve these goals is the inappropriate health services demand. This study aims to present these inappropriate health service demand determinants from data on telephone calls made to a medical advice call centre.

Methods

This study used a Brazilian medical advice call centre data sample in the period of November and December 2012 (n = 19690), which supplied data on the user’s initial request, the physician’s recommendation, information on the patient and circumstances (the day and time of the day of the telephone call). The convergence between user intent and medical recommendation consists in adequate demand; otherwise the divergence consists in an inadequate one. In this way, using a logistic regression model, the critical factors that determine inappropriate health services request could be estimated.

Results

In general, the user’s initial intent is the most critical for the inappropriate health system demand occurrence: the greater the complexity of the patient’s initial intent, the greater the chance the intent is wrong: (OR: 1.160; 95% CI: 1.113-1.210). With regard to the social characteristics, men are more likely to make inappropriate requests (OR: 1.102; 95% CI: 1038-1169); as well as youngsters are more likely to use the system incorrectly (OR = .993; 95% CI: .992 - .994). Regarding the circumstances (day and time of the call), requests in the final hours of the day and on days close to the weekend are more likely to be the inappropriate ones (OR: 1.082 for each six hour increase; 95% CI: 1.049-1.116) and weekday (OR: 1.017 for each day increase; 95% CI: 1.002-1.032).

Conclusions

The critical profile for the inappropriate use occurrence consists of males and youngsters, who use the health service in the final hours of the day and at weekends, and mainly want to use more complex services. A practical implication of this research is to provide health systems managers, supporting information to the most critical users in order to assist them in making a decision when asking for health care.

Who uses emergency departments inappropriately and when - a national cross-sectional study using a monitoring data system

BACKGROUND

Increasing pressures on emergency departments (ED) are straining services and creating inefficiencies in service delivery worldwide. A potentially avoidable pressure is inappropriate attendances (IA); typically low urgency, self-referred patients better managed by other services. This study examines demographics and temporal trends associated with IA to help inform measures to address them.

METHODS

Using a national ED dataset, a cross-sectional examination of ED attendances in England from April 2011 to March 2012 (n = 15,056,095) was conducted. IA were defined as patients who were self-referred; were not attending a follow-up; received no investigation and either no treatment or 'guidance/advice only'; and were discharged with either no follow-up or follow-up with primary care. Small, nationally representative areas were used to assign each attendance to a residential measure of deprivation. Multivariate analysis was used to predict relationships between IA, demographics (age, gender, deprivation) and temporal factors (day, month, hour, bank holiday, Christmas period).

RESULTS

Overall, 11.7% of attendances were categorized as inappropriate. IA peaked in early childhood (adjusted odds ratio (AOR) = 1.53 for both one and two year olds), and was elevated throughout late-teens and young adulthood, with odds reducing steadily from age 27 (reference category, age 40). Both IA and appropriate attendances (AA) were most frequent in the most deprived populations. However, relative to AA, those living in the least deprived areas had the highest odds of IA (AOR = 0.89 in most deprived quintile). Odds of IA were also higher for males (AOR = 0.95 in females). Both AA and IA were highest on Mondays, whilst weekends, bank holidays and the period between 8 am and 4 pm saw more IA relative to AA.

CONCLUSIONS

Prevention of IA would be best targeted at parents of young children and at older youths/young adults, and during weekends and bank holidays. Service provision focusing on access to primary care and EDs serving the most deprived communities would have the most benefit. Improvements in coverage and data quality of the national ED dataset, and the addition of an appropriateness field, would make this dataset an effective monitoring tool to evaluate interventions addressing this issue.

A proof of concept for assessing emergency room use with primary care data and natural language processing

OBJECTIVE

The objective of this study was to undertake a proof of concept that demonstrated the use of primary care data and natural language processing and term extraction to assess emergency room use. The study extracted biopsychosocial concepts from primary care free text and related them to inappropriate emergency room use through the use of odds ratios.

METHODS

De-identified free text notes were extracted from a primary care clinic in Guelph, Ontario and analyzed with a software toolkit that incorporated General Architecture for Text Engineering (GATE) and MetaMap components for natural language processing and term extraction.

RESULTS

Over 10 million concepts were extracted from 13,836 patient records. Codes found in at least 1% percent of the sample were regressed against inappropriate emergency room use. 77 codes fell within the realm of biopsychosocial, were very statistically significant (p < 0.001) and had an OR > 2.0. Thematically, these codes involved mental health and pain related concepts.

CONCLUSIONS

Analyzed thematically, mental health issues and pain are important themes; we have concluded that pain and mental health problems are primary drivers for inappropriate emergency room use. Age and sex were not significant. This proof of concept demonstrates the feasibly of combining natural language processing and primary care data to analyze a system use question. As a first work it supports further research and could be applied to investigate other, more complex problems.

Frequent use of emergency departments in Saudi public hospitals: implications for primary health care services

This study aims to determine the prevalence, factors and reasons associated with the frequent use of public emergency departments (EDs) in Riyadh, Saudi Arabia. The study employed a self-administered questionnaire to collect data from adult patients on aspects such as demographic characteristics, accessibility, and health-related factors. Bivariate and multivariate analyses were used to explore the issue. The results indicated that about 30% of respondents were considered as "frequent users" of the EDs. Males, older patients, those living closer to EDs, and patients who had chronic illnesses or were hospitalized in the past year were more likely to use EDs frequently. Moreover, the study found that patients who were labeled as "frequent users" of the EDs were also frequent users of "other" health care facilities. Health decision makers should facilitate primary health centers with necessary resources that fulfill the patients' health needs and reduce the burden on EDs.

Predicting hospital admissions at emergency department triage using routine administrative data

OBJECTIVES

To be able to predict, at the time of triage, whether a need for hospital admission exists for emergency department (ED) patients may constitute useful information that could contribute to systemwide hospital changes designed to improve ED throughput. The objective of this study was to develop and validate a predictive model to assess whether a patient is likely to require inpatient admission at the time of ED triage, using routine hospital administrative data.

METHODS

Data collected at the time of triage by nurses from patients who visited the ED in 2007 and 2008 were extracted from hospital administrative databases. Variables included were demographics (age, sex, and ethnic group), ED visit or hospital admission in the preceding 3 months, arrival mode, patient acuity category (PAC) of the ED visit, and coexisting chronic diseases (diabetes, hypertension, and dyslipidemia). Chi-square tests were used to study the association between the selected possible risk factors and the need for hospital admission. Logistic regression was applied to develop the prediction model. Data were split for derivation (60%) and validation (40%). Receiver operating characteristic curves and goodness-of-fit tests were applied to the validation data set to evaluate the model.

RESULTS

Of 317,581 ED patient visits, 30.2% resulted in immediate hospital admission. In the developed predictive model, age, PAC status, and arrival mode were most predictive of the need for immediate hospital inpatient admission. The c-statistic of the receiver operating characteristic (ROC) curve was 0.849 (95% confidence interval [CI] = 0.847 to 0.851). The goodness-of-fit test showed that the predicted patients' admission risks fit the patients' actual admission status well.

CONCLUSIONS

A model for predicting the risk of immediate hospital admission at triage for all-cause ED patients was developed and validated using routinely collected hospital data. Early prediction of the need for hospital admission at the time of triage may help identify patients deserving of early admission planning and resource allocation and thus potentially reduce ED overcrowding.

[Characteristics of the emergency health service demand in Southern Brazil]

This study evaluated the demand of emergency health service. It was performed a descriptive analyses of 1647 adults that consulted at emergency public service of Pelotas, Brazil. Older subjects, non white skin color, lower schooling, without partner, and smokers presented higher prevalence of consultations at this service when compared with the general population. Individuals waited, on average, 15 minutes to have their consultations, exams were requested in more than 40% of the visits, and intravenous medication were administered in one third of the visits. Elderly waited longer before searching the service, but they had lowest awaiting time after arriving at emergency service and had higher percentage of regular doctor and social support. Elderly had more diagnosis related to circulatory system, while among the youngest, external causes were the most frequent. The low waiting average for consultation suggest this service provide an immediate care while the great number of ill-defined signs or symptoms indicate that the provided care is provisional. It is necessary to train emergency professionals to reduce the number of tests requested and to assure that either professional as the population is conscious about the importance of a continuity of care.

Analysis of trends in emergency department attendances, hospital admissions and medical staffing in a Hong Kong university hospital: 5-year study

Background

The workload of emergency departments (ED) continually changes in response to presentations, overcrowding and availability of expertise and investigations.

Aims

To investigate changes in ED presentations and care processes, and the relationship of patient demand and ED staff resources to waiting times and processing times.

Methods

Retrospective analysis of prospectively collected administrative data from January 1999 to April 2005 in an emergency department in a university teaching hospital in Hong Kong. All patients attending the emergency department during the study period were included. Monthly attendance data were retrieved and analysed to determine both qualitative and quantitative changes in the patterns of presentation to the ED using prospectively gathered data.

Results

Total ED attendances decreased by 25% during the study with little seasonal variation. The admission rate and the use of ambulances increased steadily and significantly. Medical patients are increasing proportionately, but trauma patients are decreased in number.

Conclusion

There have been major changes in the patterns of ED attendances and ED waiting times over the study period in this teaching hospital ED. Decreasing overall ED numbers are offset by an increasingly elderly population and a more complex case mix. Reducing clinical staff numbers appears to reduce the ED’s capacity to provide timely assessments and care and to function as hospital gatekeepers. Restoring staff numbers to previous levels may improve the quality and timeliness of ED services. It is necessary to refine measures of ED complexity and workload to determine appropriate staffing levels in the future.

Inappropriate use of emergency services: a systematic review of prevalence and associated factors

This systematic review aimed to measure the prevalence of inappropriate emergency department (ED) use by adults and associated factors. The review included 31 articles published in the last 12 years. Prevalence of inappropriate ED use varied from 20 to 40% and was associated with age and income. Female patients, those without co-morbidities, without a regular physician, without a regular source of care, and those not referred to the ED by a physician also showed more inappropriate ED use, with the relative risk varying from 1.12 to 2.42. Difficulties in accessing primary health care (difficulties in setting appointments, longer waiting periods, and short business hours at the primary health care service) were also associated with inappropriate ED use. Thus, primary care requires fully qualified patient reception and efficient triage to promptly attend cases that cannot wait. It is also necessary to orient the population on situations in which they should go to the ED and on the disadvantages of consulting the ED when the case is not really urgent.

Towards integration of general practitioner posts and accident and emergency departments: a case study of two integrated emergency posts in the Netherlands

Background

Accident and emergency (A&E) departments and general practitioner (GP) posts are often used inappropriately, leading to overcrowding. In the Netherlands, increasingly more integrated emergency posts (IEPs) are being created, integrating the care provided by GP posts and A&E departments, in order to improve the provision of the emergency care.

Methods

This explorative study compares the efficiency and patient and employee satisfaction in IEPs with those in two GP posts and two A&E departments. To this end, information was retrieved from hospital and GP patient records for the first quarter of the year before and of the year after the creation of IEPs. Patients and employees were sent a questionnaire to measure their satisfaction. Lastly, groups of hospital doctors, GPs, GP assistants, and nurses were interviewed.

Results

After the creation of IEPs, there was a shift of more than fifteen percent from secondary care to primary care for emergency consultations and waiting/consultation times were shortened by more than ten percent. Compared with the control settings, patients were more satisfied about telephone contact with an IEP, but professionals working at the IEP were less satisfied with several aspects of their work.

Conclusion

IEPs could be a promising innovation to organize emergency care more efficiently; however, it might take time to convince professionals of the possible advantages. Studies involving more IEPs and longer follow-up times are needed to determine whether such integration should be stimulated.

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

OBJECTIVE

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

DESIGN

Descriptive cross-sectional study.

SETTING

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

PATIENTS

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

MAIN OUTCOME MEASURES

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

RESULTS

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

CONCLUSIONS

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

Demand for emergency health service: factors associated with inappropriate use

Background

The inappropriate use of emergency room (ER) service by patients with non-urgent health problems is a worldwide problem. Inappropriate ER use makes it difficult to guarantee access for real emergency cases, decreases readiness for care, produces negative spillover effects on the quality of emergency services, and raises overall costs.

Methods

We conducted a cross-sectional study in a medium-sized city in southern Brazil. The urgency of the presenting complaint was defined according to the Hospital Urgencies Appropriateness Protocol (HUAP). Multivariable Poisson regression was carried out to examine factors associated with inappropriate ER use.

Results

The study interviewed 1,647 patients over a consecutive 13-day sampling period. The prevalence of inappropriate ER use was 24.2% (95% CI 22.1–26.3). Inappropriate ER use was inversely associated with age (P = 0.001), longer stay in the waiting room, longer duration of symptoms and morning shift. However, the determinants of inappropriate ER use differed according age groups (P value for interaction = 0.04). Within the younger age-group (15–49 years), inappropriate ER use was higher among females, patients who reported visiting the ER because there was no other place to go, patients reporting that the doctor at the regular place of care refused to attend to them without a prior appointment, and individuals who reported that the PHC clinic which they use is open for shorter periods during the day. Among older patients (50+ years), those with highest level of education, absence of self-reported chronic diseases and lack of social support were more likely to engage in higher inappropriate ER use.

Conclusion

Efforts should be made to redirect inappropriate ER demand. Besides expanding access to, and improving the quality of primary and secondary care, it is important to mobilize social support for older patients, to enhance the relationship between different levels of care, as well as to develop campaigns to educate the public about the appropriate use of medical services.

Emergency outpatient services in the city of Berlin: factors for appropriate use and predictors for hospital admission

OBJECTIVES

To determine the proportion of patients making inappropriate use of medical care at hospital emergency rooms. To identify the factors that influence appropriateness of use and the probability of subsequent hospital admission.

METHODS

Data were collected from 815 patients at three gynaecological/internal medicine emergency clinics in Berlin, Germany using multiple data sources: (i) standardized interviews covered service use history, psychosocial variables, migration history and sociodemographics; (ii) medical data were retrieved from patients' medical records, including case histories, diagnoses and therapies; (iii) emergency room physicians were asked to evaluate patients' language comprehension, physician-patient relationship and treatment urgency. Statistical analyses included chi tests, correlational and logistic regression analyses.

RESULTS

According to a self-constructed index measuring appropriateness of emergency service use, about half of the patients' visits would have to be classified as inappropriate. Age, chronic illness and the time of day of the emergency service attendance were significantly associated with appropriateness of use. The probability of a hospital admission following the emergency treatment increased with patients' age and the physician's evaluation of treatment urgency. Remarkably, and contrary to the results of international studies, the patient's ethnicity played no significant role with respect to the appropriateness of use of emergency outpatient services or the likelihood of subsequent hospital admission.

Primary care patients in the emergency department: who are they? A review of the definition of the 'primary care patient' in the emergency department

OBJECTIVE

To review the definition of 'primary care' and 'inappropriate' patients in ED and develop a generally acceptable working definition of a 'primary care' presentation in ED.

METHOD

A Medline review of articles on primary care in ED and the definitions used.

RESULTS

A total of 34 reviewed papers contained a proposed definition or comment on the definition for potential 'primary care', 'general practice', or 'inappropriate' patients in ED. A representative definition was developed premised on the common factors in these papers: low urgency/acuity--triage categories four or five in the Australasian Triage Scale, self-referred--by definition, patients referred by general practitioner/community primary medical services are not primary care cases because a primary care service has referred them on, presenting for a new episode of care (i.e. not a planned return because planned returns are not self-referred), unlikely to be admitted (in the opinion of Emergency Nurse interviewers) or ultimately not admitted.

DISCUSSION

This definition can be applied either prospectively or retrospectively, depending on the purpose. Appropriateness must be considered in light of a legitimate role for ED in primary care and the balance of resources between primary care and emergency medicine in local settings.

The ED is an efficient place to treat ED patients

The purpose of this study was to determine what percentage of ED patients would be more efficiently treated in an offsite clinic. A stratified sample consisting of 650 ED visits were reviewed. Patient care was classified as more efficiently delivered in ED or clinic using prospectively developed criteria. Five hundred fifty-three (85%; 95% confidence interval [CI], 82-88%) visits met the definition of efficient ED utilization. One (0.15%; 95% CI, 0.01-0.99%) met the criteria for efficient clinic utilization. The other 96 (15%; 95% CI, 12-18%) failed to meet the definition of efficient for either site; 92 of these failed 2 or more clinic criteria. Only 25 (3.9%; 95% CI, 2.6-5.7%) were seen for nonacute problems. Few ED patients would be more efficiently seen in a clinic.

Workload and case-mix in a Greek emergency department

The objective of the present study was to evaluate the workload and case-mix of the Emergency Department of a referral hospital, with the aim of determining the causes of overcrowding. The study was of a descriptive prospective design and was carried out in a 700-bed university hospital covering a population of approximately 200,000 inhabitants. The total number of patient visits to the Emergency Department and hospital admissions were recorded during one year, whereas the case-mix of patients visiting the department was evaluated during 11 consecutive on-call days using a triage scale with four categories of patient severity. During the year of the study 81,110 patients (a mean of 443 visits per on-call day) visited the department, with a hospital admission rate of 14.5%. The case-mix analysis of 3389 patients who visited the department during the 11 consecutive on-call days studied revealed that 5.7% were critically ill patients, 53.8% were patients with urgent but non-critical health problems, 30% were patients with non-urgent problems and 10.5% were miscellaneous cases, probably inappropriately visiting the department. In conclusion, the Emergency Department studied is severely overcrowded in relation to the population that it covers. A great part of this overload was directly related to non-urgent cases and inappropriate visits.

Propuesta y validación del Protocolo de Adecuación de Urgencias Hospitalarias modificado

BACKGROUND AND OBJECTIVE

Hospital Emergency inappropriate attendances need to be evaluated, including emergencies that can be solved in primary care. The study aim was to validate a Hospital Emergency Appropriateness Evaluation Protocol (HEAEP) having into account patient health care setting.

MATERIAL AND METHOD

An HEAEP with explicit criteria was developed. We randomly chose 100 emergency medical records among all patients attended at the Granada Hospital Ruiz de Alda in the first quarter of 2000. Records were evaluated by six emergency specialists to compare results provided by the HEAEP.

RESULTS

The HEAEP identified as appropriate all attendances so classified by experts. As inappropriate, HEAEP only pointed out 69% of the emergency visits considered as inappropriate by experts.

CONCLUSIONS

The modified HEAEP shown a good internal validity and high reproducibility. The main advantage is to point out as inappropriate emergency attendances that can be solved in primary care.

Inappropriate Emergency Department Visits and Use of the Health Care for the Homeless Program Services by Homeless Adults in the Northeastern United States

This study tested whether the use of the Health Care for the Homeless Program (HCHP) by homeless adults was associated with reduced risk of inappropriate emergency department (ED) use. Researchers interviewed 941 homeless adults at 52 soup kitchens. Of those interviewed, 508 reported having at least 1 ED visit during the last 6 months. Then, 243 subjects' 688 ED records were retrieved. Inappropriateness of each ED use was evaluated based on clinical criteria. Logistic regressions were applied. Having two or more HCHP visits [odds ratio (OR) = 0.43, 95% confidence interval (CI) 0.19, 0.90] by homeless adults was associated with decreased odds of having inappropriate ED visits.

Predictors and outcomes of frequent emergency department users

OBJECTIVE

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Analysis of patient flow in the emergency department and the effect of an extensive reorganisation

OBJECTIVES

To evaluate the different internal factors influencing patient flow, effectiveness, and overcrowding in the emergency department (ED), as well as the effects of ED reorganisation on these indicators.

METHODS

The study compared measurements at regular intervals of three hours of patient arrivals and patient flow between two comparable periods (from 10 February to 2 March) of 1999 and 2000. In between, a structural and staff reorganisation of ED was undertaken. The main reason for each patient remaining in ED was recorded and allocated to one of four groups: (1) factors related to ED itself; (2) factors related to ED-hospital interrelation; (3) factors related to hospital itself; and (4) factors related to neither ED nor hospital. The study measured the number of patients waiting to be seen and the waiting time to be seen as effectiveness markers, as well as the percentage of time that ED was overcrowded, as judged by numerical and functional criteria.

RESULTS

Effectiveness of ED was closely related with some ED related and hospital related factors. After the reorganisation, patients who remained in ED because of hospital related or non-ED-non-hospital related factors decreased. ED reorganisation reduced the number of patients waiting to be seen from 5.8 to 2.5 (p<0.001) and waiting time from 87 to 24 minutes (p<0.001). Before the reorganisation, 31% and 48% of the time was considered to be overcrowded in numerical and functional terms respectively. After the reorganisation, these figures were reduced to 8% and 15% respectively (p<0.001 for both).

CONCLUSIONS

ED effectiveness and overcrowding are not only determined by external pressure, but also by internal factors. Measurement of patient flow across ED has proved useful in detecting these factors and in being used to plan an ED reorganisation.
