Emergency care visits at a South African hospital: Implications for healthcare services and policy.

A robust knowledge on the pattern of use of emergency care resources not only serves as an indicator of universal access to care but also provides a basis for quality improvement within the health system. This study was undertaken to describe the pattern of emergency room visits at Brits District Hospital (BDH) in North West province, South Africa. The objectives of this study were to determine the sociodemographic characteristics of emergency department (ED) users and other patterns of ED use. This was a cross-sectional descriptive study that was conducted at a district hospital. All patients who reported for emergency care in the ED in 2016 were eligible for the study. Data were extracted and analysed from a systematic sample of 355 clinical notes and hospital administrative records. The age group that visited the ED most frequently (25.3%) was 25-34 years old. A high proportion of the ED users (60%) were self-referred, and only 38% were transported by the emergency medical response services (EMRS). Few (5.6%) presentations were of a non-urgent nature. Trauma-related conditions accounted for the most frequent presentation at the ED (36.5%). Although most ED users were self-referred, their clinical presentations were appropriate and underscore the need for policy strategies to reduce the burden of trauma in the catchment populationContribution:The study findings may have an impact on future health policies by providing decision-makers with baseline information on the pattern of use of ED resources, ensuring better resource deployment and greater access to care.

Undertriage for Children With Caregivers Preferring Languages Other Than English.

Undertriage, the underestimation of acuity, can result in delayed care and potential morbidity in the emergency department (ED). Although inequities in ED care based on language preference have been noted, little is known about its association with undertriage. We evaluated for differences in undertriage based on caregiver language preference. This was a retrospective cross-sectional study of patients aged younger than 21 years, triaged as Emergency Severity Index (ESI) level 4 or 5 (nonurgent), to the pediatric ED from January 1, 2019, through January 31, 2021. Indicators of undertriage were defined as hospital admission, significant ED resource use, or return visits with admission. We used logistic regression with generalized estimating equations to measure the association of preferred language with undertriage. Of 114 266 ED visits included in the study, 22 525 (19.8%) represented patients with caregivers preferring languages other than English. These children were more likely to experience undertriage compared with those with caregivers preferring English (3.7% [English] versus 4.6% [Spanish] versus 5.9% [other languages]; Spanish versus English: odds ratio [OR], 1.3; 95% confidence interval [CI], 1.2-1.4] and other languages versus English: OR, 1.6; 95% CI, 1.2-2.2). Differences remained after adjusting for sex, insurance, mode of arrival, and clustering by triage nurse (Spanish versus English: adjusted OR, 1.3; 95% CI, 1.3-1.5) and other languages versus English: adjusted OR, 1.6; 95% CI, 1.2-2.2). Children accompanied by caregivers preferring languages other than English are more likely to be undertriaged in the pediatric ED. Efforts to improve the triage process are needed to promote equitable care for this population.

Impact of Victorian COVID-19 restrictions on emergency department presentations and hospital admissions for ophthalmic conditions

ABSTRACT Clinical Relevance Assessing the extent to which COVID-19 impacted hospitals can provide important learnings for future pandemics. Background This study aims to determine the impact of the 7-month duration COVID-19 pandemic-related lockdown orders on ophthalmology-related hospital admissions and emergency department (ED) presentations, during 2020 in Victoria, Australia. Methods Analysis was performed on Victorian statewide data from the Victorian Emergency Minimum Dataset (VEMD) and Victorian Admitted Episodes Dataset (VAED), between 1 January 2018 and 31 October 2020. Numbers of presentations and admissions for key ophthalmic conditions were stratified by age, socioeconomic status, location (metropolitan versus rural), and triage category. From the observations occurring in the pre-pandemic period (January 2018 to March 2020), a linear regression prediction model was built for each diagnosis which predicted what the presentation number in the COVID-19 period would have been if the pandemic had not occurred. Results Based on pre-COVID-19 trends, the largest decreases in expected admissions were for glaucoma (32.9%) and retinal breaks and detachments (21.2%). For the ED data, the most apparent changes were: an increase in presentations for foreign bodies (22.6%); a decrease in retinal detachments (35.5%); and a decrease in keratitis (18.4%) relative to predictions. Conclusions Hospital admissions decreased and patterns of ED attendances changed during lockdown. The findings suggest the need for the following: increased safety messaging to avoid eye injuries around the home; improved pathways for safe and rapid triaging of eye conditions in the community to ensure effective use of ED resources; and messaging to ensure that people do not delay care when they notice signs of sight-threatening conditions such as retinal detachment.

68-OR: Using Machine Learning to Improve Screening for Undiagnosed Diabetes among Emergency Department Patients

Introduction: Screening for previously undiagnosed diabetes in the emergency department (ED) can enhance early detection, which may particularly benefit patients with barriers to accessing primary care. To optimize use of limited ED resources, there is a need to identify ED patients who are at high risk. Objectives: To improve identification of ED patients with undiagnosed diabetes using machine learning (ML) . Methods: Diabetes screening by HbA1c was implemented in four EDs at an academic medical center. Patients aged 40 or older, with BMI > 25, no history of diabetes and no HbA1c result within 6 months were eligible for screening. Patients were stratified by screening result and compared across demographic and clinical characteristics, and local geographic measures of health and socioeconomic variables. ML classifier models predicting a positive screening result were trained, and were validated on a prospectively withheld subset of the cohort. Results: In the first weeks after implementation, 2423 eligible patients were identified, and 1518 (62.6%) were screened, with 114 (7.5% of those screened) found to have previously undiagnosed diabetes. Patients with diabetes more often identified as male, Hispanic or Latino, Black, or Asian, had higher BMIs and blood pressures at triage, resided in neighborhoods with higher diabetes prevalence and poverty rates, and had less prior healthcare utilization, especially in the outpatient setting. The best performing classifier models were logistic regression with elastic net regularization (AUC 0.81) and gradient-boosted trees (AUC 0.77) . These models identified a high-risk subgroup consisting of 30% of eligible patients who accounted for over 80% of newly detected cases of diabetes. Conclusions: ML models can reliably identify ED patients at high risk of having undiagnosed diabetes based on demographic, clinical, and local geographic risk factors, and could form the basis of a selective screening program.

Inequities in periodontal disease prevalence, prevention, and management.

Periodontal disease is highly prevalent and contributes to the global burden of chronic diseases. Inherent and institutional inequities contribute to the prevalence of periodontal disease by facilitating barriers to accessing dental care and maintaining good oral health. The aim of this paper is to review the inequities experienced in the dental field in relation to periodontal disease. Barriers to dental care are experienced in many countries globally. They include cost, insurance coverage, geography, physician availability, and oral health literacy. These barriers influence the frequency of dental visits, oral hygiene, and risk behaviors of individuals which impact an individual's oral health status. Most often, postponed or improper dental care leads to worsened dental conditions that are more costly and detrimental to one's wellbeing. These dental conditions, like periodontitis, fall back on the health care system for treatment through emergency department resource use and comorbidities that can develop or be worsened as a result. To reduce the global burden of chronic disease and the costs of treatments for preventable conditions, and increase oral health, corrective actions are required. Such actions may include the use of teledentistry, greater oral health education, emergency departments staffing dental practitioners, subsidies for rural or remote dental practitioners, and policy changes for universal coverage of basic dental needs.

Impact of Age on Emergency Resource Utilization and Outcomes in Pediatric and Young Adult Patients Supported with a Ventricular Assist Device.

There are minimal data describing outcomes in ambulatory pediatric and young adult ventricular assist device (VAD)-supported patient populations. We performed a retrospective analysis of encounter-level data from 2006 to 2017 Nationwide Emergency Department Sample (NEDS) to compare emergency department (ED) resource utilization and outcomes for pediatric (≤18 years, n = 494) to young adult (19-29 years, n = 2,074) VAD-supported patient encounters. Pediatric encounters were more likely to have a history of congenital heart disease (11.3% vs. 4.8%). However, Pediatric encounters had lower admission/transfer rates (37.8% vs. 57.8%) and median charges ($3,334 (IQR $1,473-$19,818) vs. $13,673 ($3,331-$45,884)) (all p < 0.05). Multivariable logistic regression modeling revealed that age itself was not a predictor of admission, instead high acuity primary diagnoses and medical complexity were: (adjusted odds ratio; 95% confidence intervals): cardiac (3.0; 1.6-5.4), infection (3.4; 1.7-6.5), bleeding (3.9; 1.7-8.8), device complication (7.2; 2.7-18.9), and ≥1 chronic comorbidity (4.1; 2.5-6.7). In this largest study to date describing ED resource use and outcomes for pediatric and young adult VAD-supported patients, we found that, rather than age, high acuity presentations and comorbidities were primary drivers of clinical outcomes. Thus, reducing morbidity in this population should target comorbidities and early recognition of VAD-related complications.

Emergency Department Utilization of Adult Cancer Patient in Korea: A Nationwide Population-Based Study, 2017-2019.

PurposeThe current study aimed to identify the overall characteristics of cancer-related emergency department (ED) visits by adult in Korea, including analyses of factors associated with ED stay time and outcomes nationwide.Materials and MethodsWe collected data on cancer-related ED visits from the National Emergency Department Information System (NEDIS) database between 2017 and 2019.ResultsED visits by cancer patients comprised 5.5% (667,935 visits) of total ED visits from 2017 to 2019, which was slightly higher than in other counties. Patients with cancer who visited the ED were over 50 years old, the majority being males, and patients with cancer visited EDs in certified tertiary hospitals more frequently than patients without cancer. In multivariate analyses, the adjusted odds ratio for a length of stay more than 8 hours in the ED of certified tertiary hospitals was 126.34 (95% confidence interval, 1.422 to 1.460) when compared to hospitals. Nevertheless, the longer the patients stayed in the ED, the more likely they were to be admitted.ConclusionThe longer ED stay and higher proportion of cancer patient hospitalizations suggest that cancer patients visit ED to be admitted as well as to receive acute care. The frequency of ED visits and admission may be adjusted to some extent depending on outpatient education, such as self-management of symptoms and situations. Improving cancer care in local communities should be met though provisions such as linking treatment between hospitals or supplying appropriate medical personnel, even for the efficient use of ED resources in hospitals.

Use of a Unique Mobile Medical Asset in COVID Monoclonal Antibody Treatment.

The COVID-19 pandemic and the subsequent surge of patients presented to emergency departments has forever changed the paradigm of delivering emergency care. The highly infectious nature of the 2019 Novel Coronavirus, or COVID-19, mandated strict environmental changes, novel patient care, and flexible strategies to continue to deliver efficient emergency care while maintaining appropriate physical distancing between suspect and non-suspect COVID-19 patients. The engagement of a unique rapidly deployable Mobile Satellite Emergency Department (MSED) with scalable capability from prompt care to resuscitation level allowed the emergency care team to optimize patient care and throughput. The MSED was strategically located adjacent to the ambulance entrance. While initially deployed to increase Emergency Department surge capacity, the MSED was repurposed to cohort and treat COVID patients with the monoclonal antibody, Bamlanivimab, who were expected to be discharged after treatment. This allowed for more efficient use of Emergency Department resources, including physical space and staffing.

Ecstasy and related drug consumption and the effect on emergency department resource use

BackgroundEcstasy and other recreational related drug use and substance related presentations to the emergency department (ED) are increasing. The aim of this study was to identify, quantify, and describe the ED resources used to care for patients diagnosed with ecstasy and related drug (ERD) use. MethodA retrospective case study design. ResultsEighty-nine patients (89%) needed one to one (n=25) and/or one to two nursing care (n=83). Security presence was required for 37 patients (37%) and the Emergency Psychiatric Service team reviewed 29 patients (29%). Most patients (n=80, 80%) received an Emergency Short Stay Unit admission, but continued to receive care in the ED, and were not transferred to the short stay unit (n=74, 92.5%). Most patients (n=86, 86%) were discharged home, after 5hr 49mins (median) in ED. ConclusionExtensive human resources were required to care for patients diagnosed with ERD use. Nursing staffing levels required to care for this patient cohort during times of peak presentations should be reviewed. It is important the government acknowledges the National Emergency Access Target is not suitable for all presenting patients. A dedicated model of care is recommended to support care requirements and reduce pressure on busy EDs.

Pediatric Emergency Department Visits at US Children's Hospitals During the COVID-19 Pandemic.

The impact of the coronavirus disease 2019 (COVID-19) pandemic on pediatric emergency department (ED) visits is not well characterized. We aimed to describe the epidemiology of pediatric ED visits and resource use during the pandemic. We conducted a cross-sectional study using the Pediatric Health Information System for ED visits to 27 US children's hospitals during the COVID-19 pandemic period (March 15, 2020, to August 31, 2020) and a 3-year comparator period (March 15 to August 31, 2017-2019). ED visit rates, patient and visit characteristics, resource use, and ED charges were compared between the time periods. We specifically evaluated changes in low-resource-intensity visits, defined as ED visits that did not result in hospitalization or medication administration and for which no laboratory tests, diagnostic imaging, or procedures were performed. ED visit rates decreased by 45.7% (average 911 026 ED visits over 2017-2019 vs 495 052 visits in 2020) during the pandemic. The largest decrease occurred among visits for respiratory disorders (70.0%). The pandemic was associated with a relative increase in the proportion of visits for children with a chronic condition from 23.7% to 27.8% (P < .001). The proportion of low-resource-intensity visits decreased by 7.0 percentage points, and total charges decreased by 20.0% during the pandemic period. The COVID-19 pandemic was associated with a marked decrease in pediatric ED visits across a broad range of conditions; however, the proportional decline of poisoning and mental health visits was less pronounced. The impact of decreased visits on patient outcomes warrants further research.

A qualitative exploration of value and waste in a Trinidadian emergency department patient flow process: perspectives of patients and clinicians

PurposeA process that does not include the customer's value may not be effective in providing care. This study aimed to identify value and waste in an emergency department (ED) patient flow process from a patient and clinician perspective.Design/methodology/approachA qualitative case study was conducted in an ED in Trinidad and Tobago. Observations and informal conversational interviews with clinicians (n = 33) and patients (n = 50) explored patient flow, value and waste. Thematic analysis was used to create a framework on valuable and wasteful aspects in the ED patient flow process.FindingsValuable aspects led to direct improvements in the patient's health or an exchange of information in the process. Wasteful aspects were those with no patient activity, no direct ED clinical involvement, or resulted in a perceived inappropriate use of ED resources. However, there was a disparity in responses between clinicians and patients with clinicians identifying more features in the process.Research limitations/implicationsThe single case study design limits the generalizability of findings to other settings. This study did not specifically explore the influence of age and gender on what mattered to patients in ED services. Future studies would benefit from exploring whether there are any age and gender differences in patient perspectives of value and waste. Further research is needed to validate the usefulness of the framework in a wider range of settings and consider demographic factors such as age and gender.Practical implicationsThe study has produced a framework which may be used to improve patient flow in a way that maximized value to its users. A collaborative approach, with active patient involvement, is needed to develop a process that is valuable to all. The single case study design limits the generalizability of findings to other settings.Originality/valueQualitative methods were used to explicitly explore both value and waste in emergency department patient flow, incorporating the patient perspective. This paper provides an approach that decision makers may use to refine the ED patient flow process into one that flows well, improves quality and maximizes value to its users.

An Increasing Burden of Disease: Emergency Department Visits Among Patients With Ventricular Assist Devices From 2010 to 2017.

BackgroundWith a growing population of patients supported by ventricular assist devices (VADs) and the improvement in survival of this patient population, understanding the healthcare system burden is critical to improving outcomes. Thus, we sought to examine national estimates of VAD‐related emergency department (ED) visits and characterize their demographic, clinical, and outcomes profile. Additionally, we tested the hypotheses that resource use increased and mortality improved over time.Methods and ResultsThis retrospective database analysis uses encounter‐level data from the 2010 to 2017 Nationwide Emergency Department Sample. The primary outcome was mortality. From 2010 to 2017, >880 million ED visits were evaluated, with 44 042 VAD‐related ED visits identified. The annual mean visits were 5505 (SD 4258), but increased 16‐fold from 2010 to 2017 (824 versus 13 155). VAD‐related ED visits frequently resulted in admission (72%) and/or death (3.0%). Median inflation‐adjusted charges were $25 679 (interquartile range, $7450, $63 119) per encounter. The most common primary diagnoses were cardiac (22%), and almost 30% of encounters were because of bleeding, stroke, or device complications. From 2010 to 2017, admission and mortality decreased from 82% to 71% and 3.4% to 2.4%, respectively (P for trends <0.001, both).ConclusionsWe present the first study using national‐level data to characterize the growing ED resource use and financial burden of patients supported by VAD. During the past decade, admission and mortality rates decreased but remain substantial; in 2017 ≈1 in every 40 VAD ED encounters resulted in death, making it critical that clinical decision–making be optimized for patients with VAD to maximize good outcomes.

Trends in dental-related visits to a tertiary hospital emergency department in Saudi Arabia

Introduction: Emergency medicine department visits for odontalgia, related to traumatic and non traumatic dental events has seen a shift towards increase in cases. Emergency departments provide palliative care especially for the non traumatic dental injuries Aims: To explore the trends of emergency department (ED) visits for dental-related conditions in Saudi Arabia. The study also aimed to analyze visit management patterns, including procedures, prescriptions, and recall visits. Materials and Methods: A cross-sectional retrospective observational study was done using simple random sampling on dental emergency visit data to the ED at hospitals under renowned university of health sciences in Riyadh and Al-Ahsa between January 2016 and May 2019. Results and Discussion: A total of 5050 charts were included. An increase in dental emergency visits was observed between 2016 and 2017. Pulpal and periapical lesions were the most frequently diagnosed conditions every year (53.83% of all dental-related ED visits), and traumatic injuries were the least frequently (6.37%) diagnosed condition. Conclusion: Dental-related visits to EDs in Saudi Arabia increased remarkably from 2016 to 2019. Pulpal and periapical conditions were the most frequent cause of dental-related ED visits. To ensure better use of ED time and resources, it is imperative to raise public awareness of what types of urgent dental conditions require an ED visit, as well as to increase the number of public health unit dental clinics and their ease of access.

Greater admissions, mortality and cost of heart failure in adults with congenital heart disease

ObjectiveLimited contemporary data exist regarding outcomes and resource use among adults with congenital heart disease and heart failure (ACHD-HF). This study compared outcomes, emergency department (ED) and hospital resource use,...

Emergency Physician and Advanced Practice Provider Diagnostic Testing and Admission Decisions in Chest Pain and Abdominal Pain.

We compare utilization of diagnostic resources and admissions in emergency department (ED) patients with chest pain and abdominal pain when managed by advanced practice providers (APPs) and physicians. We used 2016 to 2019 data from a national emergency medicine group. We compared visits managed by physicians and APPs based on demographics and observed resource utilization (labs, radiography, computed tomography) use and hospital admission/transfer, stratified by patient age. To reduce selection bias, we created inverse propensity score weights (IPWs). To estimate the average treatment effect for APP visits for each outcome, we included IPWs in a multivariable linear probability model with a dummy variable indicating treatment by an APP and used a facility fixed effect. We then estimated the average treatment effect comparing physician to APP visit for all visits and for discharged visits separately, stratified by the study outcomes. Sensitivity analyses were performed using different cohort definitions and adjusting for past medical history. In chest pain, we included 77,568 visits seen by 1,011 APPs and 586,031 visits seen by 1,588 physicians. In abdominal pain, we included 184,812 ED visits seen by 1,080 APPs and 761,230 visits seen by 1,689 physicians. For both chest pain and abdominal pain visits, physicians saw more older adult patients (55+ years) and admitted a higher percentage of visits than APPs. For chest pain, physicians saw more circulatory system diseases (70.7% vs. 58.6%); APPs saw more respiratory system diseases (17.1% vs. 9.8%). In abdominal pain, emergency physicians saw more digestive system diseases (28.5% vs. 23.3%); APPs saw more genitourinary system diseases. After matching with IPW, predicted probabilities of laboratory, radiology, and admissions either did not vary or were slightly lower for APPs compared to physicians for all outcomes. Sensitivity analyses showed similar results, including controlling for past medical history. Diagnostic testing and hospitalization rates for chest pain and abdominal pain between APPs and physicians is largely similar after matching for severity and complexity. This suggests that APPs do not have observably higher use of ED and hospital resources in these conditions in this national group.

LO67: Alcohol-related emergency department visits by youth aged 12-24: demographics and resource utilization at Kingston Health Sciences Centre

Introduction: Recent evidence shows an increase in alcohol-related emergency department (ED) visits among youth. We sought to quantify the impact of ED visits (type and frequency, patient characteristics and resource use) related to alcohol in our centre. Methods: This was a chart review of patients aged 12-24 with alcohol-related ED visits between Sept 2013-Aug 2017. The National Ambulatory Care Reporting System (NACRS) database was searched for visits alcohol related ICD-10 codes. The Canadian Hospital Injury Reporting and Prevention Program (CHIRPP) database was also searched using the keyword alcohol. Duplicate visits were removed. Visits were excluded if patients had a history of psychosis, were held in the ED for psychiatric assessment, were homeless, were inmates from a correctional institute, if alcohol use was not mentioned and for complaints of sexual assault/intimate partner violence. Data was abstracted by two reviewers using a standard form with predetermined variables. Differences were resolved with third party adjudication. Interrater reliability of the reviewers was assessed with Kappa scores through duplicate review of 10% of randomly selected charts. A further 10% were assessed by a 3rd reviewer for extraction accuracy. Results: 3,256 ED visits were identified with 777 removed via predefined exclusion criteria. 2,479 visits were reviewed with a male predominance (54.3%). More than half of all patients (50.9%) arrived via ambulance. Assigned CTAS levels were Resuscitation: 1% Emergent: 9.9% Urgent: 48.2% Less Urgent: 35.7% Non-Urgent: 4.2% (missing 1%). The median LOS was 2.9 hrs (IQR 1.8-4.6). All visits were subclassified into mutually exclusive categories: injury (51.8%), acute intoxication (45.1%) and mental health issue (3.2%). Males were more likely to present with injury (62.4% vs 42.6%, p &lt; 0.01). Females were more likely to present with acute intoxication (53.3% vs 46.7%, p &lt;0.01) and mental health issues (59.5% vs 40.5%, P = 0.01). ED resource use was notable: 483 (19.4%) had imaging tests and 1216 (49.1%) had some medical intervention (blood test, fluids or medication). 57 (2.3%) patients were admitted and there was one death from an alcohol related MVC. Conclusion: Alcohol-related ED visits by youth are common in our centre and utilize substantial prehospital and in-hospital resources. Identification of effective harm reduction strategies should be a research priority.

Validation of the Emergency Severity Index (Version 4) for the Triage of Adult Emergency Department Patients With Active Cancer.

Patients with active cancer account for a growing percentage of all emergency department (ED) visits and have a unique set of risks related to their disease and its treatments. Effective triage for this population is fundamental to facilitating their emergency care. We evaluated the validity of the Emergency Severity Index (ESI; version 4) triage tool to predict ED-relevant outcomes among adult patients with active cancer. We conducted a prespecified analysis of the observational cohort established by the National Cancer Institute-supported Comprehensive Oncologic Emergencies Research Network's multicenter (18 sites) study of ED visits by patients with active cancer (N=1075). We used a series of χ2 tests for independence to relate ESI scores with 1) disposition, 2) ED resource use, 3) hospital length of stay, and 4) 30-day mortality. Among the 1008 subjects included in this analysis, the ESI distribution skewed heavily toward high acuity (>95% of subjects had an ESI level of 1, 2, or 3). ESI was significantly associated with patient disposition and ED resource use (p values<0.05). No significant associations were observed between ESI and the non-ED based outcomes of hospital length of stay or 30-day mortality. ESI scores among ED patients with active cancer indicate higher acuity than the general ED population and are predictive of disposition and ED resource use. These findings show that the ESI is a valid triage tool for use in this population for outcomes directly relevant to ED care.

The cost of diagnostic uncertainty: a prospective economic analysis of febrile children attending an NHS emergency department

BackgroundPaediatric fever is a common cause of emergency department (ED) attendance. A lack of prompt and definitive diagnostics makes it difficult to distinguish viral from potentially life-threatening bacterial causes, necessitating a cautious approach. This may result in extended periods of observation, additional radiography, and the precautionary use of antibiotics (ABs) prior to evidence of bacterial foci. This study examines resource use, service costs, and health outcomes.MethodsWe studied an all-year prospective, comprehensive, and representative cohort of 6518 febrile children (aged < 16 years), attending Alder Hey Children’s Hospital, an NHS-affiliated paediatric care provider in the North West of England, over a 1-year period. Performing a time-driven and activity-based micro-costing, we estimated the economic impact of managing paediatric febrile illness, with focus on nurse/clinician time, investigations, radiography, and inpatient stay. Using bootstrapped generalised linear modelling (GLM, gamma, log), we identified the patient and healthcare provider characteristics associated with increased resource use, applying retrospective case-note identification to determine rates of potentially avoidable AB prescribing.ResultsInfants aged less than 3 months incurred significantly higher resource use than any other age group, at £1000.28 [95% CI £82.39–£2993.37] per child, (p < 0.001), while lesser experienced doctors exhibited 3.2-fold [95% CI 2.0–5.1-fold] higher resource use than consultants (p < 0.001). Approximately 32.4% of febrile children received antibiotics, and 7.1% were diagnosed with bacterial infections. Children with viral illnesses for whom antibiotic prescription was potentially avoidable incurred 9.9-fold [95% CI 6.5–13.2-fold] cost increases compared to those not receiving antibiotics, equal to an additional £1352.10 per child, predominantly resulting from a 53.9-h increase in observation and inpatient stay (57.1 vs. 3.2 h). Bootstrapped GLM suggested that infants aged below 3 months and those prompting a respiratory rate ‘red flag’, treatment by lesser experienced doctors, and Manchester Triage System (MTS) yellow or higher were statistically significant predictors of higher resource use in 100% of bootstrap simulations.ConclusionThe economic impact of diagnostic uncertainty when managing paediatric febrile illness is significant, and the precautionary use of antibiotics is strongly associated with increased costs. The use of ED resources is highest among infants (aged less than 3 months) and those infants managed by lesser experienced doctors, independent of clinical severity. Diagnostic advances which could increase confidence to withhold antibiotics may yield considerable efficiency gains in these groups, where the perceived risks of failing to identify potentially life-threatening bacterial infections are greatest.

Emergency department use among kidney transplant recipients in the United States.

Patients with end-stage renal disease use the emergency department (ED) at a 6-fold higher rate than do other US adults. No national studies have described ED use rates among kidney transplant (KTx) recipients, and the factors associated with higher ED use. We examined a cohort of 132725 adult KTx recipients in the United States Renal Data System (2005-2013). Data on ED visits, hospitalization, and outpatient nephrology visits were obtained from Medicare claims databases. Nearly half (46.1%) of KTx recipients had at least one ED visit (1.61 ED visits/patient-year [PY]), and 39.7% of ED visits resulted in hospitalization in the first year posttransplantation. ED visit rate was high in the first 30days (5.26 visits/PY) but declined substantially thereafter (1.81 visits/PY in months 1-3; 1.13 visits/PY in months 3-12 posttransplantation). ED visit rates were higher in the first 30days versus rates for dialysis patients but less than half the rate thereafter. Female sex, public insurance, medical comorbidities, longer pretransplantation dialysis vintage, and delayed graft function were associated with higher ED use in the first year post-KTx. Policies and strategies addressing potentially preventable ED visits should be promoted to help improve patient care and increase efficient use of ED resources.

Emergency physician sex and emergency department resource use.

We investigated whether there are differences in emergency department (ED) patient management associated with emergency physician (EP) sex, specifically in terms of ordering investigations and hospital admissions. We included all EPs working as consultants for at least 24 consecutive months at a Spanish ED during an 8-year period. Every annual period was considered independently. The classificatory variable was EP sex. For every annual period we compiled age and years of experience of each EP, the number of patients who attended, and patient distribution in triage categories. To analyze ED resource use by each EP and period, we recorded percentages of blood tests, radiography, ultrasonography, computerized tomography (CT) scan, and hospital admission orders. Fifty EPs (27 women and 23 men) were included, 291 annual periods were analyzed (132 for women and 159 for men) and 256 524 patient attendances were recorded (114 086 by women and 142 438 by men). Blood tests were ordered in 57.2% of cases, radiography in 58.0%, ultrasounds in 5.0%, CT scans in 7.0%, and hospitalizations in 28.4%. Compared with men, women ordered 6.8% (95% confidence interval 6.1-7.5%) more blood tests, 4.6% (4.3-5.3%) more radiographies, 15.2% (11.6-18.9%) more ultrasonographies, 11.1% (8.1-14.1%) more CT scans, and 12.1% (10.8-13.4%) more hospitalizations. These differences maintained statistical significance in the stratified analysis by EP experience, and were observed for most of the years analyzed. Female EPs order more investigations and admit more patients, although from our results the reason for this is unclear, and the impact on healthcare effectiveness and patient outcome is unknown.
