Inappropriate Emergency Department Research Articles

Prognostic clinical decision support for pneumonia in the emergency department: A randomized trial.

Hospitalization rates for childhood pneumonia vary widely. Risk-based clinical decision support (CDS) interventions may reduce unwarranted variation. We conducted a pragmatic randomized trial in two US pediatric emergency departments(EDs) comparing electronic health record (EHR)-integrated prognostic CDS versus usual care for promoting appropriate ED disposition in children (<18 years) with pneumonia. Encounters were randomized 1:1 to usual care versus custom CDS featuring a validated pneumonia severity score predicting risk for severe in-hospital outcomes. Clinicians retained full decision-making authority. The primary outcome was inappropriate ED disposition, defined as early transition to lower- or higher-level care. Safety and implementation outcomes were also evaluated. The study enrolled 536 encounters (269 usual care and 267 CDS). Baseline characteristics were similar across arms. Inappropriate disposition occurred in 3% of usual care encounters and 2% of CDS encounters (adjusted odds ratio: 0.99, 95% confidence interval: [0.32, 2.95]) Length of stay was also similar and adverse safety outcomes were uncommon in both arms. The tool's custom user interface and content were viewed as strengths by surveyed clinicians (>70% satisfied). Implementation barriers include intrinsic (e.g., reaching the right person at the right time) and extrinsic factors (i.e., global pandemic). EHR-based prognostic CDS did not improve ED disposition decisions for children with pneumonia. Although the intervention's content was favorably received, low subject accrual and workflow integration problems likely limited effectiveness.Clinical Trials Registration: NCT06033079.

Emergency department visits by nursing home residents. A retrospective Italian study of administrative databases from 2015 to 2019

BackgroundVisits to Emergency Departments (ED) can be traumatic for Nursing Home (NH) residents. In Italy, the rate of ED visits by NH residents was recently calculated as 3.3%. The reduction of inappropriate ED visits represents a priority for National Healthcare Systems worldwide. Nevertheless, research on factors associated with ED visits is still under-studied in the Italian setting. This study has two main aims: (i) to describe the baseline characteristics of NH residents visiting ED at regional level; (ii) to assess the characteristics, trends, and factors associated with these visits.MethodsA retrospective study of administrative data for five years was performed in the Piedmont Region. Data from 24,208 NH residents were analysed. Data were obtained by merging two ministerial databases of residential care and ED use. Sociodemographic and clinical characteristics of the residents, trends, and rates of ED visits were collected. A Generalized Linear Model (GLM) regression was used to evaluate the factors associated with ED visits.ResultsIn 5 years, 12,672 residents made 24,609 ED visits. Aspecific symptoms (45%), dyspnea (17%) and trauma (16%) were the most frequent problems reported at ED. 51% of these visits were coded as non-critical, and 58% were discharged to the NH. The regression analysis showed an increased risk of ED visits for men (OR = 1.61, 95% CI 1.51–1.70) and for residents with a stay in NH longer than 400 days (OR = 2.19, 95% CI 2.08–2.31).ConclusionsOur study indicates that more than half of NH residents’ ED visits could potentially be prevented by treating residents in NH. Investments in the creation of a structured and effective network within primary care services, promoting the use of health technology and palliative care approaches, could reduce ED visits and help clinicians manage residents on-site and remotely.

Patient's Perspective for their Non-Urgent Presentations to the Emergency Department in Najran City

Aim of Study: To explore patients’ perspectives regarding the reasons why some less urgent, or non-urgent patients prefer to attend emergency departments (EDs) instead of using other more appropriate healthcare services. Methods: This study followed a quantitative cross-sectional design. The study obtained and analyzed emergency attendance data from King Khalid Hospital, Najran City. A study questionnaire was designed by the researcher to interview 400 ED patients, who inappropriately attended the ED, to identify the reasons for their inappropriate attendance to the ED. Data collection was performed during the period of two months (November-December, 2022) to explore the proportions of different attendances that were deemed inappropriate according to the hospital’s followed triage system. The interviews were conducted with the non-urgent and less urgent patients during their waiting times. Results: The age of 18.3% of patients were &lt;30 years old, while 28.5% were 30-39 years old. More than half of the participants’ visits were non-urgent, while 43.25% were less-urgent, 55.3% of patients visited the ED before due to similar complaints, and 46% visited a primary health care center before their ED visits. The main reasons for visiting the ED instead of the primary healthcare center (PHCC) were to save time (49.3%) and to get an earlier appointment (48%). Patients’ triage levels differed significantly according to their age groups (p&lt;0.001), nationality (p=0.022), educational level (p=0.022), marital status (p=0.002), ED visits due to similar complaints (p&lt;0.001), and previously visiting the PHCC for the current health problem (p=0.002). Triage levels also differed significantly according to some reasons for choosing to go to the ED instead of the PHCC, especially to get an earlier appointment (p=0.044), preferring the healthcare services provided by the ED (p=0.005), having a nearby ED (p=0.001), or being at the hospital at that time (p=0.002). Conclusions: There is a clear relationship between inappropriate ED visits and certain associated factors, indicating that prevention would be best targeted to certain categories, such as Saudi, younger, and educated patients. The main reasons for inappropriate ED visits are to save time and to avoid getting a late appointment. Recommendations: This study emphasized the importance of implementing proper health education and redirecting patients with inappropriate ED visits. Conducting a detailed analysis of the shortages in the utilization of primary healthcare resources is a pressing necessity. Further nationwide studies on patients’ perspective for non-urgent ED presentations are largely needed. Key Words: Emergency Department, Triage, Quantitative Research, Najran City, Saudi Arabia

Efficacy of a Patient Education Session for Cancer Patients Receiving Immunotherapy

ObjectivesOur research questions include: What are gaps in cancer patients’ knowledge about immunotherapy? What is the efficacy of an education session in improving cancer patients’ knowledge about immunotherapy and reducing inappropriate emergency department (ED) visits? Data SourcesFrom July 2020 to September 2021, we invited cancer patients receiving immunotherapy to participate in a one-on-one patient education session and pre-test/post-test surveys. The patient education session included an oral presentation following National Comprehensive Cancer Network guidelines, video on immunotherapy mechanisms of action, and review of written materials and alert cards. The surveys assessed patient knowledge of immunotherapies’ mechanisms of action, adverse effects and their management, and health literacy. Survey data were paired with data abstracted from the electronic health record on patient ED utilization and demographic characteristics. ConclusionBefore the education session, knowledge gaps about immunotherapy included understanding the medical term “itis,” side effects of immunotherapy, and treatment for side effects of immunotherapy. Overall, the education session significantly improved cancer patients’ knowledge about immunotherapy. The education session addressed knowledge gaps by significantly increasing patients’ knowledge of immunotherapy mechanisms of action, recognition of side effects, and ability to define the medical term “itis”. Because our sample had low inappropriate ED utilization, we could not assess the impact of the education session on inappropriate ED utilization. Implications for Nursing PracticeA multicomponent strategy for patient education was effective in improving overall knowledge uptake, especially among patients who initially had the least knowledge. Future studies should continue to explore whether patient education decreases inappropriate ED utilization.

Non-Urgent Pediatric Presentations to the Emergency Department, Khamis Mushayt Maternity and Children Hospital, Saudi Arabia

Aim of Study: To explore parents’ perspectives regarding why parents (caregivers) prefer to escort their less urgent, or non-urgent sick children to the emergency departments (EDs) instead of using other more appropriate healthcare services. Methods: This study followed a quantitative cross-sectional design at Khamis Mushayt Maternity and Children’s Hospital (KMMCH). A study questionnaire was designed by the researchers to interview parents of 400 children who inappropriately attended the ED to identify the reasons for their inappropriate attendance at the ED. Data collection was performed during the period of January 2023 to explore the proportions of different attendances that were deemed inappropriate according to the hospital’s followed triage system. The interviews were conducted with parents/caregivers of non-urgent and less urgent children during their waiting times. Results: The age of 18.3% of parents was &lt;30 years, while 28.5% were 30-39 years old. More than half of the parents’ visits were non-urgent, while 43.25% were less-urgent, 55.3% of patients visited the ED before due to similar complaints, while 46% visited a primary health care center before their ED visits. The main reasons for visiting the ED instead of the primary healthcare centers (PHCCs) were to save time (49.3%) and to get an earlier appointment (48%). Patients’ triage levels differed significantly according to parents’ age groups (p&lt;0.001), nationality (p=0.022), educational level (p=0.022), ED visits for similar complaints (p&lt;0.001), and previously visiting the PHCC for the current health problem (p=0.002). Triage levels also differed significantly according to some reasons for choosing to go to the ED instead of the PHCC, especially to get an earlier appointment (p=0.044), preferring the healthcare services provided by the ED (p=0.005), having a nearby ED (p=0.001), or being at the hospital at that time (p=0.002). Conclusions: There is a clear relationship between inappropriate ED visits and certain associated factors, indicating that prevention would be best targeted to certain categories, such as Saudi, younger, and educated parents. The main reasons for inappropriate ED visits are to save time and to avoid getting a late appointment. Recommendations: This study emphasized the importance of implementing proper health education and redirection of patients with inappropriate ED visits. Conducting a detailed analysis of the shortages in the utilization of primary healthcare resources is a pressing necessity. Further nationwide research on patients’ perspective for non-urgent ED presentations is largely needed. Key Words: Emergency Department, Triage, Children, Non-urgent level, Less urgent level.

Early discharge from maternity ward in response to the COVID-19 pandemic: Impact on emergency attendance

Background: In response to the coronavirus disease 2019 (COVID-19) epidemic, our maternity department had to rapidly implement a protocol for early postpartum discharge. We evaluated the benefits and risks of early postpartum discharge.Methods: We performed an observational, single-center case–control study over a 3 month-period during the COVID-19 outbreak (from June 1 to August 31, 2020), following implementation of the early discharge policy. Newborns were classified into an early discharge group (within 48–72 h of a vaginal delivery and within 72–96 h of a cesarean delivery) or a standard discharge group (more than 72 h after a vaginal delivery and more than 96 h after a cesarean delivery). The primary outcome measure was inappropriate pediatric emergency department visits within 28 days of delivery.Results: A total of 546 newborns were included. A total of 22 (8.9%) of the 246 newborns in the early discharge group attended the pediatric emergency department vs. 30 (10.0%) of the 300 newborns in the standard discharge group (p = 0.65). Nine visits (40.9%) were considered inappropriate in the early discharge group vs. 13 (43.3%) in the standard discharge group (p = 0.83). Likewise, the intergroup difference in the hospital readmission rate was not statistically significant.Discussion: The implementation of early discharge and early follow-up did not result in a significantly greater need (vs. standard discharge) for inappropriate emergency visit or hospital readmission during the first 28 days postpartum, regardless of the parity and breastfeeding status.

Bridging the Gap Between Hospital and Community Mental Health Services for Frequent Emergency Department Visitors

Inappropriate emergency department (ED) use is costly. A system navigation service was developed to connect individuals with repeated ED presentations due to mental health or substance use to community services. Management, staff, and clients (n = 37) participated in interviews or focus groups to identify implementation challenges and associated solutions. Referrals were improved through ED staff support and automating the process. The outreach process, decreased service duration, and prompt support with connection to services facilitated program delivery. Two newly funded programs addressed the limited capacity of other services, and technology facilitated communication. Attention to partnerships and flexibility in the design were essential.

Impact of the COVID-19 Pandemic on Healthcare-Seeking Behaviors among Frequent Emergency Department Users: A Cohort Study.

In 2020, Taiwan’s healthcare system faced a notable burden imposed by the coronavirus disease (COVID-19) pandemic. Emergency department (ED) is a high-risk area for severe acute respiratory syndrome coronavirus 2 transmission. The effect of COVID-19 on the utilization of ED services among frequent ED users remains unknown. This cohort study determined the impact of the COVID-19 pandemic on healthcare-seeking behaviors among frequent ED users at Taipei City Hospital, Taiwan. We included ED users aged ≥ 18 years admitted to Taipei City Hospital during February 2019–January 2020 (before the pandemic) and February 2020–January 2021 (during the pandemic). Frequent ED users were patients with four or more ED visits per year. Stepwise logistic regression was performed to identify predictors of frequent ED use during the COVID-19 pandemic. Frequent ED users had shorter hospital stays in the ED during the pandemic. After adjusting for sociodemographic factors and other covariates, patients with a triage status of level 4–5, pneumonia diagnosis, giddiness, or dyspnea were more likely frequent ED visitors during the COVID-19 pandemic. To reduce the risk of acquiring COVID-19, it is important to utilize territorial healthcare or telehealth to avoid inappropriate ED visits for patients with a low level of risk or chronic disease.

The impact of the COVID-19 pandemic and governor mandated stay at home order on emergency department super utilizers.

BackgroundDespite the trend of rising Emergency Department (ED) visits over the past decade, researchers have observed drastic declines in number of ED visits due to the COVID-19 pandemic. The purpose of the current study was to examine the impact of the COVID-19 pandemic and governor mandated Stay at Home Order on ED super utilizers.MethodsThis was a retrospective chart review of patients presenting to the 12 emergency departments of the Franciscan Mission of Our Lady Hospital System in Louisiana between January 1, 2018 and December 31, 2020. Patients who were 18 years of age or older and had four ED visits within a one-year period (2018, 2019, or 2020) were classified as super-utilizers. We examined number and category of visits for the baseline period (January 2018 – March 2020), the governor's Stay at Home Order, and the subsequent Reopening Phases through December 31, 2020.ResultsThe number of visits by super utilizers decreased by over 16% when the Stay at Home Order was issued. The average number of visits per week rose from 1010.63 during the Stay at Home Order to 1198.09 after the Stay at Home Order was lifted, but they did not return to Pre-COVID levels of approximately 1400 visits per week in 2018 and 2019. When categories of visits were examined, this trend was found for emergent visits (p < 0.001) and visits related to injuries (p < 0.001). Non-emergent visits declined during the Stay at Home Order compared to the baseline period (p < 0.001), and did not increase significantly during reopening compared to the Stay at Home Order (p = 0.87). There were no changes in number of visits for psychiatric purposes, alcohol use, or drug use during the pandemic.ConclusionsSignificant declines in emergent visits raise concerns that individuals who needed ED treatment did not seek it due to COVID-19. However, the finding that super utilizers with non-emergent visits continued to visit the ED less after the Stay at Home Order was lifted raises questions for future research that may inform policy and interventions for inappropriate ED use.

How did the COVID-19 Pandemic Affect Inappropriate Adult Emergency Department Attendances?: A Prospective Cross-Sectional Study

How did the COVID-19 Pandemic Affect Inappropriate Adult Emergency Department Attendances?: A Prospective Cross-Sectional Study

Association of inappropriate polypharmacy with emergency department visits in older patients receiving anti-neoplastic therapy: a population-based study.

We aimed to investigate the prevalence and predicting factors of inappropriate polypharmacy including potentially inappropriate medications (PIMs) and drug-drug interactions (DDIs) and their associations with emergency department (ED) visits in older Korean patients receiving anti-neoplastic therapy. We identified older patients receiving anti-neoplastic therapy in 2016 from the National Health Claims database. We investigated the prevalence of inappropriate polypharmacy comprising PIMs and DDIs in geriatric patients according to the 2019 American Geriatrics Society Beers Criteria® and chemotherapeutic DDIs using LexicompOnlineTM and Micromedex®. A nested case-control study was conducted to evaluate the associations between inappropriate polypharmacy and ED visits during anti-neoplastic therapy. Multivariate logistic regressions were performed after adjusting for age, sex, cancer diagnosis, prior ED visits, Charlson Comorbidity Index, and type of anti-neoplastic therapy. Inappropriate polypharmacy, its subtype PIMs, geriatric, and chemotherapeutic DDIs were observed in 85.4%, 80.4%, 17.3%, and 37.9% of the 21,956 patients receiving anti-neoplastic therapy, respectively. After adjusting for confounding factors, the presence of inappropriate polypharmacy (adjusted odds ratio (aOR) 2.15, 95% confidence interval (CI) 1.97-2.35), 2 or more PIMs (aOR 1.85, 95% CI 1.68-2.02), 2 or more chemotherapeutic DDIs (aOR 2.88, 95% CI 2.54-3.28), and geriatric DDIs (aOR 1.61, 95% CI 1.43-1.80) increased the likelihood of ED visits during anti-neoplastic therapy. This nationwide study showed that inappropriate polypharmacy was prevalent and increased the risk of ED visits in older patients receiving anti-neoplastic therapy. Study findings suggested a need to implement deprescribing strategies in this population.

Affordable Care Act did not reduce inappropriate use of emergency room services

Abstract Background The US Patient Protection and Affordable Care Act of 2010 (ACA) has several provisions to increase access to health insurance among Americans. Prior to ACA, emergency departments (ED) served as a safety net to uninsured as most hospitals are required to provide stabilizing treatment to patients with emergency medical conditions regardless of their ability to pay. The ACA increased the number of insured, improved access to primary care and was expected to reduce high cost ED utilization Methods This retrospective cross-sectional study used ED data from a US Midwest suburban medium size hospital (November 2009 - January 2017) to analyze the patterns of ER utilization pre- and post-ACA. The data (n = 423,548) excluded ambulance deliveries; 5-level Emergency Severity Index was re-coded as urgent/non-urgent for each visit. Analysis included age, sex, race, mode of arrival, disposition, insurance, visit day and time as other predictors in binary logistic regression. Results Non-urgent visit proportion increased from 34.5% in 2009 to 49.1% in 2016; odds of a visit being urgent are lower after ACA (Exp(B)=0.684; 95%CI 0.675,0.694) with stronger effect for pediatric (age&amp;lt;18) population (Exp(B)=0.487, CI 0.471, 0.503). ACA did not change ED utilization by working population, however, in comparison to people with commercial insurance, patients without recorded insurance are less likely to have a true urgent visit (Exp(B)=0.845; CI 0.83, 0.86). Among other factors predicting ED visit urgency are race and insurance type. Conclusions Expensive ER care is still provided for non-urgent care. Access to alternative type of care and public health awareness efforts should focus on subpopulations with high inappropriate ED use. Key messages Affordable Care Act (2010) did not improve efficiency of emergency room utilization. Additional effort are needed to increase access to primary care and awareness of ER use for specific subpopulations.

Time from suspected thrombotic thrombocytopenic purpura to initiation of plasma exchange and impact on survival: A 10-year provincial retrospective cohort study

BackgroundThrombotic thrombocytopenic purpura (TTP) is a thrombotic microangiopathy (TMA) with significant morbidity and mortality. Guidelines recommend initiating plasma exchange within 4–8 h of suspected diagnosis. It is unclear what are real-world practice patterns and whether delays >8 h increases mortality. ObjectivesTo determine if delayed initiation of plasma exchange is associated with increased risk of death and complications. MethodsIn this retrospective cohort study, we evaluated the time from suspected diagnosis to plasma exchange in all adults presenting with suspected TTP to apheresis centres in Alberta, Canada (2008–2018). Among patients with acquired TTP, the association between delayed plasma exchange and risk of death was evaluated using Cox regression. ResultsOverall 190 episodes of suspected TTP were included among 163 individuals. Acquired TTP was confirmed in 61 patients. Inappropriate Emergency Department triage occurred in 59%. The median time from suspected diagnosis to first plasma exchange was 10.7 h; 59% had delayed plasma exchange >8 h, among whom plasma infusion was administered in only 45%. 36% of suspected TTP and 13% of confirmed TTP patients died. Delayed plasma exchange between 8 and 24 h was not associated with a significantly higher risk of death (adjusted hazards ratio; aHR 0.63, 95% CI 0.08–4.83) in confirmed TTP. On the other hand, the risks of death (aHR 1.40, 95% CI 0.20–9.79) and major thrombotic events (aHR 2.9, 95% CI 0.6–12.8) were markedly increased with >24 h delay. ConclusionsOur study demonstrated that TTP care in a real-world setting is discordant with expert guidelines due to multiple barriers. There is a gradient of increased mortality risk and thrombotic complications with longer treatment delays, although the study is likely underpowered.

LO38: Reducing inappropriate urine culture testing in the emergency department

Background: Urinary tract infections (UTI) are a common emergency department (ED) presentation. Urine cultures (UC) are frequently ordered to confirm the diagnosis, however, it can be challenging to differentiate between a true infection and asymptomatic bacteriuria (ASB) which does not generally benefit from antibiotics. This over-treatment of ASB leads to serious adverse side effects, growing antimicrobial resistance and increased healthcare costs. By reducing inappropriate ED urine culture testing, we can concomitantly avoid the false positives that contribute to this large-scale problem. Aim Statement: We aimed to reduce ED urine culture testing at Credit Valley Hospital, a large community hospital based in Mississauga, Ontario by 30%, from a baseline average of 97 cultures per 1000 ED visits in 2017, to 68 cultures per 1000 ED visits by year end 2019. Measures &amp; Design: Multiple PDSA cycles were ran with our multi-disciplinary ED team. Our interventions to encourage rational urine culture testing are three-fold, including (1) medical directive optimization (removal of routine sending of UC), (2) individualized physician feedback and (3) physician education with introduction of a clinical decision aid. Our outcome measure is rate of UC per 1000 ED patient visits with a balance measure of rate of 30-day ED return visit of hospital admission for patients with a UTI. Evaluation/Results: Despite a parallel surge in ED volumes, we observed a significant decrease in urine culture testing, from an annual average of 97 cultures per 1000 ED visits to 60 cultures per 1000 ED visits in 2019 year-to-date. There was no increase in the rate of ED 30-day return visit or admission for UTI or a diagnostic equivalent. Discussion/Impact: Our multipronged approach effectively decreased the rate of UC testing during the study period. ED physicians provide higher quality care with judicious use of resources to guide diagnosis and management. Active ongoing interventions include our transition to a 2-step UC order protocol (uncoupling urinalysis with culture) using BD vacutainer urine collection products, which will allow for 48 hour storage of uncompromised urine. Further work will leverage our knowledge and experience with optimizing urine culture testing to other culture specimens.

Dedicated homeless clinics reduce inappropriate emergency department utilization.

BackgroundThe homeless patient population is known to have a high occurrence of inappropriate emergency department (ED) utilization. The study hospital initiated a dedicated homeless clinic targeting patients experiencing homelessness with a combination of special features. We aim to determine whether this mode of care can reduce inappropriate ED utilization among homeless patients.MethodsWe conducted a retrospective observational study from July 1, 2017 to Dec 31, 2017. The study enrolled all homeless patients who visited any hospital regular clinic, dedicated homeless clinic, and ED at least once during the study period. ED homeless patients were divided into four groups (A: no clinic visits; B: those who only visited hospital regular clinic; C: those who only visited dedicated homeless clinic; and D: those who visited both hospital regular clinic and dedicated homeless clinic). The New York University algorithm was used to determine appropriate ED utilization. We compared inappropriate ED utilization among patients from these groups. Multivariate logistic regression was used to determine the risks of different clinical visits in association with inappropriate ED utilization.ResultsA total of 16,323 clinic and 8511 ED visits occurred among 5022 unique homeless patients, in which 2450 unique patients were seen in hospital regular clinic, 784 patients in dedicated homeless clinic, 688 patients in both hospital regular clinic and dedicated homeless clinic, and 1110 patients with no clinic visits. Twenty‐nine percent (230/784) of patients from dedicated homeless clinic utilized the ED, among which 21% (175/844) of their ED visits were considered inappropriate. In contrast, 40% of patients from hospital regular clinic utilized the ED, among which 29% were inappropriate (P < 0.001). The adjusted odds ratio (OR) was 0.61 (95% confidence interval [CI] = 0.50–0.74, P < 0.001) on dedicated homeless clinic predicting inappropriate ED visits in multivariate logistic regression.ConclusionImplementing a dedicated homeless clinic with these features can reduce ED inappropriate utilization among patients experiencing homelessness.

Assessing appropriateness of pediatric emergency department visits: is it even possible?

Numerous studies reported on the frequency of, and factors associated with inappropriate or unnecessary emergency department (ED) visits using clinician judgment as the gold standard of appropriateness. This study evaluated the reliability of clinician judgment for assessing appropriateness of pediatric ED visit. We conducted a retrospective cohort study comparing 3 clinicians' determination of ED visit appropriateness with and without guidance from a three-question structured algorithm. We used a cohort of scheduled ED return visits deemed appropriate by the index treating clinician between May 1, 2012, and April 30, 2013. We measured the level of agreement among three clinician investigators with and without use of the structured algorithm. A total of 207 scheduled ED return visits were reviewed by the primary clinician reviewer who agreed with the index treating clinician for 79/207 visits (38.2%). Among a random subset of 90 return visits reviewed by all three clinicians, agreement was 67% with a Fleiss' Kappa of 0.30 (0.17-0.44). Using a three-question algorithm based on objective criteria, agreement with the index treating provider increased to 115/207 (55.6%). Although an important contributor to pediatric ED overcrowding, unnecessary or inappropriate visits are difficult to identify. We demonstrated poor reliability of clinician judgment to determine appropriateness of ED return visits, likely due to variability in clinical decision-making and risk-tolerance, social and systems factors impacting access and use of health care. We recommend that future studies evaluating the appropriateness of ED use standardized, objective criteria rather than clinician judgment alone.

The impact of primary health care reform on hospital emergency department overcrowding: Evidence from the Portuguese reform.

The reduction in inappropriate utilization of hospitals' emergency departments (EDs) is usually an important objective of primary health care (PHC) reforms. Existing literature provides mixed evidence on the effectiveness of PHC reforms in reducing inappropriate utilization of ED. We assess whether the specific PHC reforms ongoing in Portugal since 2005, and in particular the creation of family health units (FHUs), were successful in reducing inappropriate utilization of EDs and provide a contribution to the debate of which PHC models contribute to reduce overuse of EDs. We use patient-level data of 117 391 ED visits from two nonurban hospitals in Portugal to estimate a multivariate logistic regression that assesses the impact of different PHC models on inappropriate ED visits. Patients in our sample had four different models of PHC provision: the new FHU type A or type B and the old personalized health care units (PHUs), with or without a specific family physician assigned. The percentage of episodes that correspond to appropriate visits to the ED is 2% higher for patients enrolled in an FHU type B and 0.8% higher for users of FHU type A, when compared with users enrolled in PHU. Having an assigned family physician increases appropriate use of the ED by 1%. Portugal's PHC reform was successful in reducing inappropriate utilization of EDs.

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

BackgroundInappropriate 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....
