Emergency department patient classification systems: A systematic review

BACKGROUND: The emergency department is a dynamic environment with a high throughput of patients. The clinical stability of patients varies considerably. In order to provide optimal care for patients a responsive staffing pattern is required. There is a need for a valid and reliable, prospective, emergency department patient classification system to set adequate nurse staffing levels in the UK. AIMS AND OBJECTIVES: To conduct a systematic review of the literature and determine the validity, reliability, strengths and weaknesses of emergency department patient classification systems. METHODS: The following electronic databases were searched for years 1985-2004: MEDLINE; CINAHL; COCHRANE Library databases DARE, CDSR, CCTR, BioMedNet Reviews, National Research Register (NRR). Manual searches were also conducted and relevant references retrieved from those listed in key papers, reports, theses and dissertations. Studies were also retrieved by contacting researchers in the field. RESULTS: Twelve patient classification systems met all the inclusion criteria. Only three systems reported evidence of good validity and reliability: the ED Patient Needs Matrix developed in the US, the Conner's Tool (a modified version of the ED Patient Needs Matrix) developed in Australia and the Jones Dependency Tool developed in the UK. CONCLUSION: There are very few patient classification systems developed for use in the ED setting that have demonstrated good validity and reliability. The Jones Dependency Tool is a simple, easy to use prospective, patient classification system that has demonstrated good validity and reliability in the UK.     

Optimizing emergency department care transitions to outpatient settings: A systematic review and meta-analysis

IntroductionSuboptimal transitions from the emergency department (ED) to outpatient settings can result in poor care continuity, and subsequently higher costs to the healthcare system. We aimed to systematically review care transition interventions (CTIs) for adult patients to understand how effective ED-based CTIs are in reducing return visits to the ED and increasing follow-up visits with primary care physicians.MethodsWe searched multiple databases and identified eligible published RCTs of ED-based CTIs affecting outpatient follow-up rates, ED readmission and hospital admission. Two independent authors reviewed titles and abstracts for potential inclusion and selected studies for full review. Study quality was assessed using the Cochrane risk-of-bias tool. ED-based CTIs were classified using a care continuity framework.ResultsOur search generated 28,807 articles; 112 were selected for full-text review. Data were abstracted from 42 articles that met inclusion criteria. Pooling data from 20 studies (n = 8178 patients) found a relative increase in outpatient follow-up with ED-based CTIs compared to routine care (odds ratio 1.79, 95% confidence interval [CI] 1.43, 2.24). However, ED-based CTIs (20 studies, n = 8048 patients) had no significant effect on ED readmissions (odds ratio 1.02, 95% CI 0.87, 1.20]) or hospital admission after ED discharge (13 studies, n = 5742 patients) (odds ratio 0.99, 95% CI 0.86, 1.14) when compared to routine care. Twenty-two studies encompassed CTIs supporting all three functions of care continuity (information, communication and coordination).ConclusionsED-based CTIs do not appear to reduce ED revisit or hospital admission after ED discharge but are effective in increasing follow-up.     

Ketamine for acute suicidality in the emergency department: A systematic review

IntroductionThere are no emergent pharmaceutical interventions for acute suicidal ideation, a common presenting complaint in the ED. Ketamine is a NMDA agonist frequently used by ED physicians for sedation and analgesia. Prior evidence from studies conducted in inpatient psychiatry units suggests that ketamine may have a role in alleviating treatment-resistant depression as well as suicidal ideation.MethodsPubMed, MEDLINE, and Cochrane reviews were queried for articles related to keywords ketamine, suicidality, suicidal ideation, and emergency department/room. Relevant articles were selected and reviewed by two separate authors.ResultsThree relevant, prospective studies were identified with a mean sample size of 25.7. Each was performed using 0.2 mg/kg ketamine for individuals receiving active treatment. Each study reported a decrease in depressive symptoms among those receiving ketamine. One study reported a significant reduction in SI when compared to placebo at 90 min that became non-significant by 230 min. No significant adverse events were reported in any study.ConclusionCurrent evidence suggests that ketamine is a promising, safe potential intervention for acute suicidality in the ED. Convincing evidence for efficacy of ketamine for acute suicidal ideation remains lacking, and this promising potential intervention should be further investigated.     

Chronic pain and frequent use of emergency department: A systematic review

IntroductionEmergency department (ED) overcrowding is an important issue in healthcare worldwide. A small group of patients account for a disproportionate number of ED visits and a few studies have suggested that chronic pain (CP) sufferers may be part of that group. The aim of this study was to review all studies having examined the association between CP and frequent use of ED services.MethodsA systematic review of the literature was performed. The CINAHL, PsycINFO, PubMed and Scopus databases were searched from January 1997 to August 2019, using a strategy containing the keywords frequent use, CP and ED. Two independent reviewers screened articles and assessed methodological quality using the Joanna Briggs Institute tool for prevalence studies. To be included in the review, studies had to: (1) document frequent use of ED services; (2) evaluate CP patients; and (3) use regression models. Studies were excluded if they addressed cancer pain; evaluated an intervention; or targeted an exclusively paediatric population. A narrative synthesis was conducted.ResultsOf the 1182 articles identified, 927 remained after removing duplicates and 47 remained after the evaluation of titles and abstracts, which were read completely. Finally, five articles, published between 2004 and 2016, were included in the study. Every study showed that CP was associated with higher ED visits. Two studies documented that frequent users had a higher level of disability than non-frequent users, or that disability was associated with frequent use.ConclusionsThis review suggests that CP is associated with frequent use of ED services.     

Review article: A systematic review of emergency department incident classification frameworks

As in any part of the hospital system, safety incidents can occur in the ED. These incidents arguably have a distinct character, as the ED involves unscheduled flows of urgent patients who require disparate services. To aid understanding of safety issues and support risk management of the ED, a comparison of published ED specific incident classification frameworks was performed. A review of emergency medicine, health management and general medical publications, using Ovid SP to interrogate Medline (1976–2016) was undertaken to identify any type of taxonomy or classification‐like framework for ED related incidents. These frameworks were then analysed and compared. The review identified 17 publications containing an incident classification framework. Comparison of factors and themes making up the classification constituent elements revealed some commonality, but no overall consistency, nor evolution towards an ideal framework. Inconsistency arises from differences in the evidential basis and design methodology of classifications, with design itself being an inherently subjective process. It was not possible to identify an ‘ideal’ incident classification framework for ED risk management, and there is significant variation in the selection of categories used by frameworks. The variation in classification could risk an unbalanced emphasis in findings through application of a particular framework. Design of an ED specific, ideal incident classification framework should be informed by a much wider range of theories of how organisations and systems work, in addition to clinical and human factors.     

Barriers to effective screening for domestic violence by registered nurses in the emergency department

Triage nurses in the emergency department are in a unique position to screen for domestic violence. This study, using Orlando's theory with a focus on two of her five major concepts, identifies barriers that prevent effective screening for domestic violence. A quantitative survey was distributed to 101 registered nurses employed in a large emergency department. Results identified three major barriers and a relationship between age and inservice attendance on domestic violence. Education on abuse and resources should be essential in nursing school curricula. Policy development and review should be part of an annual, mandatory inservice for all emergency nurses.     

Barriers to medication adherence in the emergency department: A cross-sectional study

BackgroundMedication nonadherence is a common problem that leads to increased healthcare utilization. It is unclear how patient insight and attitude towards their medications affect adherence in the ED. Furthermore, it is unclear how perceived medication importance differs between patients and ED physicians.MethodsWe conducted a cross sectional study of adult patients presenting to 2 academic emergency departments from April 2015 to October 2016. Demographic data were collected and questions were asked regarding medication knowledge, perceived importance, and adherence. We also compared perceived importance of medications between patients and two physician raters. Inter-rater agreement was reported as raw percentages, and categorical data were compared using chi-squared analysis.ResultsWe identified 1268 patients, representing 4634 individual medications. We identified a significant association between knowledge of medications and perceived importance (p < .05). Secondarily, importance level was highly associated with medication adherence (p < .05). When ranking those medications that were considered “least” and “most” important among each patient's med list, our two physicians agreed with patients only 34.1% and 37% of the time respectively, as opposed to 62% and 62.8% agreement between each other.ConclusionsThese data suggest that there is a difference in perceived medication importance between ED physicians and ED patients. Knowledge of a medication's purpose is significantly associated with perceived importance, while this importance appears to be significantly associated with compliance. These results suggest that concerted efforts by ED physicians and staff to educate patients on the utility and importance of their medications may improve adherence.     

Factors associated with imaging overuse in the emergency department: A systematic review

Background

Emergency departments (ED) are sites of prevalent imaging overuse; however, determinants that drive imaging in this setting are not well-characterized. We systematically reviewed the literature to summarize the determinants of imaging overuse in the ED.

Review article: Common emergency department presenting complaints of prisoners: A systematic review

Prisoners are a particularly vulnerable minority group whose healthcare needs and management differ substantially from the general population. The overall burden of disease of prisoners is well documented; however, little is known regarding the aetiology and frequency of prisoners’ acute medical complaints requiring an ED visit. Objectives of the review were to identify, review and appraise existing literature regarding prisoners’ presentations to EDs. We performed systematic electronic searches in MEDLINE, EMBASE, PsycINFO, PubMed, Cochrane, and Web of Science using MeSH terms and keywords. Two reviewers abstracted data and conducted quality appraisal using the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. Nine articles met the predefined inclusion criteria. Apart from two European studies in the past 5 years, there is a scarcity of literature primarily addressing the common presenting complaints to EDs by prisoners. Existing studies demonstrated that prisoners have a disproportionately high burden of traumatic, infectious and psychiatric disease requiring emergency treatment. With the increasing number of emergency presentations made by prisoners each year, it is vital that further research is undertaken to identify trends of these acute medical complaints in order to ensure optimal therapeutic outcomes for prisoners.     

Adherence to guideline creation recommendations for suicide prevention in the emergency department: A systematic review

ObjectivesSuicide rates in the United States rose 35.2% from 1999-2018. As emergency department (ED) providers often have limited training in management of suicidal patients and minimal access to mental health experts, clinical practice guidelines (CPGs) may improve care for these patients. However, clinical practice guidelines that do not adhere to quality standards for development may be harmful both to patients, if they promote practices based on flawed evidence, and to ED providers, if used in malpractice claims. In 2011, the Institute of Medicine created standards to determine the trustworthiness of CPGs. This review assessed the adherence of suicide prevention CPGs, intended for the ED, to these standards. Secondary objectives were to assess the association of adherence both with first author/organization specialty (ED vs non-ED) and with inclusion of recommendations on substance use, a potent risk factor for suicide.MethodsThis is a systematic review of available suicide-prevention CPGs for the ED in both peer-reviewed and gray literature. This review followed the PRISMA standards for reporting systematic reviews.ResultsOf 22 included CPGs, the 7 ED-sponsored CPGs had higher adherence to quality standards (3.1 vs 2.4) and included the highest-rated CPG (ICAR²E) identified by this review. Regardless of specialty, nearly all CPGs included some mention of identifying or managing substance use.ConclusionsMost suicide prevention CPGs intended for the ED are written by non-ED first authors or organizations and have low adherence to quality standards. Future CPGs should be developed with more scientific rigor, include a multidisciplinary writing group, and be created by authors working in the practice environment to which the CPG applies.
