Screening, detection and management of delirium in the emergency department - a pilot study on the feasibility of a new algorithm for use in older emergency department patients: the modified Confusion Assessment Method for the Emergency Department (mCAM-ED).

ABSTRACT: Delirium in emergency department (ED) patients occurs frequently and often remains unrecognized. Most instruments for delirium detection are complex and therefore unfeasible for the ED. The aims of this pilot study were first, to confirm our hypothesis that there is an unmet need for formal delirium assessment by comparing informal delirium ratings of ED staff with formal delirium assessments performed by trained research assistants. Second, to test the feasibility of an algorithm for delirium screening, detection and management, which includes the newly developed modified Confusion Assessment Method for the Emergency Department (mCAM-ED) at the ED bedside. Third, to test interrater reliability of the mCAM-ED.This was a pilot study with a pre-post-test design with two data collection periods before and after the implementation of the algorithm. Consecutive ED patients aged 65 years and older were screened and assessed in the ED of a tertiary care center by trained research assistants. The delirium detection rate of informal ratings by nurses and physicians was compared with the standardized mCAM-ED assessment performed by the research assistants. To show the feasibility at the ED bedside, defined as adherence of ED staff to the algorithm, only post-test data were used. Additionally, the ED nurses' assessments were analyzed qualitatively. To investigate the agreement between research assistants and the reference standard, the two data sets were combined.In total, 207 patients were included in this study. We found that informal delirium assessment was inappropriate, even after a teaching intervention: Sensitivity of nurses to detect delirium without formal assessment was 0.27 pretest and 0.40 post-test, whilst sensitivity of physicians' informal rating was 0.45 pre-test and 0.6 post-test. ED staff demonstrated high adherence to the algorithm (76.5%). Research assistants assessing delirium with the mCAM-ED demonstrated a high agreement compared to the reference standard (kappa?=?0.729).Informal assessment of delirium is inadequate. The mCAM-ED proved to be useful at the ED bedside. Performance criteria need to be tested in further studies. The mCAM-ED may contribute to early identification of delirious ED patients.

Project description:ObjectivesDeep sedation in the emergency department (ED) is common, increases deep sedation in the ICU, and is negatively associated with outcome. Limiting ED deep sedation may, therefore, be a high-yield intervention to improve outcome. However, the feasibility of conducting an adequately powered ED-based clinical sedation trial is unknown. Our objectives were to assess trial feasibility in terms of: 1) recruitment, 2) protocol implementation and practice change, and 3) safety. Patient-centered clinical outcomes were assessed to better plan for a future large-scale clinical trial.DesignPragmatic, multicenter ( n = 3), prospective before-after pilot and feasibility trial.SettingThe ED and ICUs at three medical centers.PatientsConsecutive, adult mechanically ventilation ED patients.InterventionsAn educational initiative aimed at reliable ED sedation depth documentation and reducing the proportion of deeply sedated patients (primary outcome).Measurements and main resultsSedation-related data in the ED and the first 48 ICU hours were recorded. Deep sedation was defined as a Richmond Agitation-Sedation Scale of -3 to -5 or a Sedation-Agitation Scale of 1-3. One thousand three hundred fifty-six patients were screened; 415 comprised the final population. Lighter ED sedation was achieved in the intervention group, and the proportion of deeply sedated patients was reduced from 60.2% to 38.8% ( p < 0.01). There were no concerning trends in adverse events (i.e., inadvertent extubation, device removal, and awareness with paralysis). Mortality was 10.0% in the intervention group and 20.4% in the preintervention group ( p < 0.01). Compared with preintervention, the intervention group experienced more ventilator-free days [22.0 (9.0) vs 19.9 (10.6)] and ICU-free days [20.8 (8.7) vs 18.1 (10.4)], p < 0.05 for both.ConclusionsThis pilot trial confirmed the feasibility of targeting the ED in order to improve sedation practices and reduce deep sedation. These findings justify an appropriately powered clinical trial regarding ED-based sedation to improve clinical outcomes.

Project description:IntroductionDelirium is a dangerous syndrome of acute brain dysfunction that is common in the emergency department (ED), especially among the geriatric population. Most systematic reviews of interventions for delirium prevention and treatment have focused on inpatient settings. Best practices of effective delirium care in ED settings have not been established. The primary objective of this study is to identify pharmacologic and non-pharmacologic interventions as applied by physicians, nursing staff, pharmacists and other ED personnel to prevent incident delirium and to shorten the severity and duration of prevalent delirium in a geriatric population within the ED.Methods and analysisSearches using subject headings and keywords will be conducted from database inception through June 2020 in MEDLINE, EMBASE, Web of Science, PsychINFO, CINAHL, ProQuest Dissertations and Theses Global and Cochrane CENTRAL as well as grey literature. Database searches will not be limited by date or language. Two reviewers will identify studies describing any interventions for delirium prevention and/or treatment in the ED. Disagreements will be settled by a third reviewer. Pooled data analysis will be performed where possible using Review Manager. Risk ratios and weighted difference of means will be used for incidence of delirium and other binary outcomes related to delirium, delirium severity or duration of symptoms, along with 95% CIs. Heterogeneity will be measured by calculating I 2, and a forest plot will be created. If significant heterogeneity is identified, metaregression is planned using OpenMeta to identify possible sources of heterogeneity.Ethics and disseminationThis is a systematic review of previously conducted research; accordingly, it does not constitute human subjects research needing ethics review. This review will be prepared as a manuscript and submitted for publication to a peer-reviewed journal, and the results will be presented at conferences.Prospero trial registration numberCRD42020169654.

Project description:BackgroundHousing insecurity is prevalent among emergency department (ED) patients. Despite a surge of interest in screening for patients' social needs including housing insecurity, little research has examined ED social needs interventions. We worked together with government and community partners to develop and pilot test a homelessness prevention intervention targeted to ED patients with drug or unhealthy alcohol use.MethodsWe approached randomly sampled patients at an urban public hospital ED, May to August 2019. Adult patients were eligible if they were medically stable, not incarcerated, spoke English, had unhealthy alcohol or any drug use, and were not currently homeless but screened positive for risk of future homelessness using a previously developed risk screening tool. Participants received a three-part intervention: (1) brief counseling and referral to treatment for substance use delivered through a preexisting ED program; (2) referral to Homebase, an evidence-based community homelessness prevention program; and (3) up to three troubleshooting phone calls by study staff. Participants completed surveys at baseline and 6 months.ResultsOf 2183 patients screened, 51 were eligible and 40 (78.4%) participated; one later withdrew, leaving 39 participants. Participants were diverse in age, gender, race, and ethnicity. Of the 32 participants reached at 6 months, most said it was very or extremely helpful to talk to someone about their housing situation (n = 23, 71.9%) at the baseline ED visit. Thirteen (40.6%) said their housing situation had improved in the past 6 months and 16 (50.0%) said it had not changed. Twenty participants (62.5%) had made contact with a Homebase office. Participants shared ideas of how to improve the intervention.ConclusionsThis pilot intervention was feasible and well received by participants though it required a large amount of screening to identify potentially eligible patients. Our findings will inform a larger future trial and may be informative for others seeking to develop similar interventions.

Project description:IntroductionOpioid use disorder (OUD) and related comorbid conditions are highly prevalent among patients presenting to emergency department (ED) settings. Research has developed few comprehensive disease management strategies for at-risk patients presenting to the ED that both decrease illicit opioid use and improve initiation and retention in medication treatment for OUD (MOUD).MethodsThe research team conducted a pilot pragmatic clinical trial that randomized 40 patients presenting to a single ED to a collaborative care intervention (n = 20) versus usual care control (n = 20) conditions. Interviewers blinded to patient intervention and control group status followed-up with participants at 1, 3, and 6 months after presentation to the ED. The 3-month Emergency Department Longitudinal Integrated Care (ED-LINC) collaborative care intervention for patients at risk for OUD included: 1) a Brief Negotiated Interview at bedside, 2) overdose education and facilitation of MOUD, 3) longitudinal proactive care management, 4) utilization of the statewide health information exchange platform for 24/7 tracking of recurrent ED utilization, and 5) weekly caseload supervision that incorporated measurement-based care treatment assessment with stepped-up care for patients with recalcitrant symptoms.ResultsOverall, the ED-LINC intervention was feasibly delivered and acceptable to patients. The pilot study achieved >80% follow-up rates at 1, 3, and 6 months. In adjusted longitudinal mixed model regression analyses, no statistically significant differences existed in days of opioid use over the past 30 days for ED-LINC intervention patients when compared to patients receiving usual care (incidence-rate ratio (IRR) 1.50, 95% CI 0.54-4.16). The unadjusted mean number of days of illicit opioid use decreased at the 1-month and 3-month follow-up time points for both groups. ED-LINC intervention patients had increased rates of MOUD initiation compared to control patients (50% versus 30%); intervention versus control comparisons did not achieve statistical significance, although power to detect significant differences in the pilot was limited.ConclusionsThe ED-LINC intervention for patients with OUD can be feasibly implemented and warrants testing in larger scale, adequately powered randomized pragmatic clinical trial investigations.Clinicaltrialsgov NCT03699085.

Project description:Recent health policy changes have focused efforts on reducing emergency department (ED) visits as a way to reduce costs and improve quality of care. This was a systematic review of interventions based outside the ED aimed at reducing ED use.This study was designed as a systematic review. We reviewed the literature on interventions in five categories: patient education, creation of additional non-ED capacity, managed care, prehospital diversion, and patient financial incentives. Studies written in English, with interventions administered outside of the ED, and a comparison group where ED use was an outcome, were included. Two independent reviewers screened search results using MEDLINE, Cochrane, OAIster, or Scopus. The following data were abstracted from included studies: type of intervention, study design, population, details of intervention, effect on ED use, effect on non-ED health care use, and other health and financial outcomes. Quality of individual articles was assessed using Grading of Recommendations Assessment, Development, and Evaluation (GRADE) guidelines.Of 39 included studies, 34 were observational and five were randomized controlled trials. Two of five studies on patient education found reductions in ED use ranging from 21% to 80%. Out of 10 studies of additional non-ED capacity, four showed decreases of 9% to 54%, and one a 21% increase. Both studies on prehospital diversion found reductions of 3% to 7%. Of 12 studies on managed care, 10 had decreases ranging from 1% to 46%. Nine out of 10 studies on patient financial incentives found decreases of 3% to 50%, and one a 34% increase. Nineteen studies reported effect on non-ED use with mixed results. Seventeen studies included data on health outcomes, but 13 of these only included data on hospitalizations rather than morbidity and mortality. Seven studies included data on cost outcomes. According to the GRADE guidelines, all studies had at least some risk of bias, with four moderate quality, one low quality, and 34 very low quality studies.Many studies have explored interventions based outside the ED to reduce ED use in various populations, with mixed evidence. Approximately two-thirds identified here showed reductions in ED use. The interventions with the greatest number of studies showing reductions in ED use include patient financial incentives and managed care, while the greatest magnitude of reductions were found in patient education. These findings have implications for insurers and policymakers seeking to reduce ED use.
