Old and New Geriatric Screening Tools in a Belgian Emergency Department: A Diagnostic Accuracy Study.

To compare the diagnostic accuracy of the Identification of Seniors at Risk, the Flemish version of Triage Risk Screening Tool, and the interRAI Emergency Department Screener for predicting prolonged emergency department (ED) length of stay, hospitalization (following index ED stay), and unplanned ED readmission at 30 and 90 days among older (aged ≥70 years) community-dwelling adults admitted to the ED. Single-center, prospective, observation study. ED with embedded observation unit in University Hospitals Leuven (Belgium). A total of 794 patients (median age = 80 years; 55% female) were included. Study nurses collected data using semistructured interviews and patient record review during ED admission. Outcome data were collected with patient record review. Hospitalization (following index ED stay) and unplanned ED readmission at 30 and 90 days occurred in 67% (527/787) of patients and in 12.2% (93/761) and 22.1% (168/761) of patients, respectively. For all outcomes at cutoff 2, the three screening tools had moderate to high sensitivity (range = 0.71-0.90) combined with (very) low specificity (range = 0.14-0.32) and low accuracy (range = 0.21-0.67). At all cutoffs, likelihood ratios and interval likelihood ratios had no or small impact (range = 0.46-3.95; zero was not included) on the posttest probability of the outcomes. For all outcomes, area under the receiver operating characteristics curve varied in the range of 0.49 to 0.62. Diagnostic characteristics of all screening tools were comparable. None of the tools accurately predicted the outcomes as a stand-alone index. Future studies should explore the clinical effectiveness and implementation aspects of ED-specific minimum geriatric assessment and intervention strategies. J Am Geriatr Soc 68:1454-1461, 2020.

Unplanned readmission prevention by a geriatric emergency network for transitional care (URGENT): a prospective before-after study

BackgroundURGENT is a comprehensive geriatric assessment (CGA) based nurse-led care model in the emergency department (ED) with geriatric follow-up after ED discharge aiming to prevent unplanned ED readmissions.MethodsA quasi-experimental study (sequential design with two cohorts) was conducted in the ED of University Hospitals Leuven (Belgium). Dutch-speaking, community-dwelling ED patients aged 70 years or older were eligible for enrolment. Patients in the control cohort received usual care. Patient in the intervention cohort received the URGENT care model.A geriatric emergency nurse conducted CGA and interdisciplinary care planning among older patients identified as at risk for adverse events (e.g. unplanned ED readmission, functional decline) with the interRAI ED Screener© and clinical judgement of ED staff. Case manager follow-up was offered to at risk patients without hospitalization after index ED visit. For inpatients, geriatric follow-up was guaranteed on an acute geriatric ward or by the inpatient geriatric consultation team on a non-geriatric ward if considered necessary.Primary outcome was unplanned 90-day ED readmission. Secondary outcomes were ED length of stay (LOS), hospitalization rate, in-hospital LOS, 90-day higher level of care, 90-day functional decline and 90-day post-hospitalization mortality.ResultsAlmost half of intervention patients (404/886 = 45.6%) were categorized at risk. These received on average seven advices. Adherence rate to advices on the ED, during hospitalization and in community care was 86.1, 74.6 and 34.1%, respectively. One out of four at risk patients without hospitalization after index ED visit accepted case manager follow-up. Unplanned ED readmission occurred in 170 of 768 (22.1%) control patients and in 205 of 857 (23.9%) intervention patients (p = .11). The intervention group had shorter ED LOS (12.7 h versus 19.1 h in the control group; p < .001), but higher rate of hospitalization (70.0% versus 67.0% in the control group; p = .003).ConclusionsThe URGENT care model shortened ED LOS and increased the hospitalization rate, but did not prevent unplanned ED readmissions. A geriatric emergency nurse could improve in-hospital patient management, but failed to introduce substantial out-hospital case-management.Trial registrationThe protocol of this study was registered retrospectively with ISRCTN (ISRCTN91449949; registered 20 June 2017).

Unplanned Readmission prevention by Geriatric Emergency Network for Transitional care (URGENT): protocol of a prospective single centre quasi-experimental study

BackgroundInternational guidelines recommend adapting the classic emergency department (ED) management model to the needs of older adults in order to ameliorate post-ED outcomes among this vulnerable group. To improve the care for older ED patients and especially prevent unplanned ED readmissions, the URGENT care model was developed.MethodsThe URGENT care model is a nurse-led, comprehensive geriatric assessment based care model in the ED with geriatric follow-up after ED discharge. A prospective single centre quasi-experimental study (sequential design with two cohorts) is used to evaluate its effectiveness on unplanned ED readmission compared to usual ED care. Secondary outcome measures are hospitalization rate, ED length of stay, in-hospital length of stay, higher level of care, functional decline and mortality.DiscussionURGENT builds on previous research with adaptations tailored to the local context and addresses the needs of older patients in the ED with a special focus on transition of care. Although the selected approaches have been tested in other settings, evidence on this type of innovative care models in the ED setting is inconclusive.Trial registrationThe study protocol is registered retrospectively with ISRCTN (ISRCTN91449949).

MP09: Incidence of emergency department induced delirium: a Canadian two years prospective study

Introduction: Prevalence and incidence of delirium in older patients admitted to acute and long-term care facilities ranges between 9.6% and 89% but little is known in the context of emergency department (ED) incident delirium. Literature regarding the incidence of delirium in the ED and its potential impacts on hospital length of stay (LOS), functional status and unplanned ED readmissions is scant, its consequences have yet to be clearly identified in order to orient modern acute medical care. Methods: This study is part of the multicenter prospective cohort INDEED study. Three Canadian EDs completed the two years prospective study (March-July 2015 and Feb-May 2016). Patients aged 65 years old, initially free of delirium with an ED stay 8hours were followed up to 24h after ward admission. Patients were assessed 2x/day during their entire ED stay and up to 24 hours on hospital ward by research assistants (RA). The primary outcome of this study was incident delirium in the ED or within 24 h of ward admission. Functional and cognitive status were assessed using validated Older Americans’ Resources and Services and the Telephone Interview for Cognitive Status- modified tools. The Confusion Assessment Method (CAM) was used to detect incident delirium. ED and hospital administrative data were collected. Inter-observer agreement was realized among RA. Results: Incident delirium was not different between sites, nor between phases, nor between times from one site to another. All phases confounded, there is between 7 to 11% of ED related incident delirious episodes. Differences were seen in ED LOS between sites in non-delirious patients, but also between some sites for delirious participants (p&lt;0.05). Only one site had a difference in ED LOS between their delirious and non-delirious patients, respectively of 52.1 and 40.1 hours (p&lt;0.05). There is also a difference between sites in the time between arrival to the ED and the incidence of delirium (p=0.003). Kappa statistics were computed to measure inter-rater reliability of the CAM. Based on an alpha of 5%, 138 patients would allow 80% power for an estimated overall incidence proportion of 15 % with 5% precision.. Other predictive delirium variables, such as cognitive status, environmental factors, functional status, comorbidities, physiological status, and ED and hospital length of stay were similar between sites and phases. Conclusion: The fact that incidence of delirium was the same for all sites, despite the differences of ED LOS and different time periods suggest that many other modifiable and non-modifiable factors along LOS influenced the incidence of ED induced delirium. Emergency physician should concentrate on improving senior-friendly environment for the ED.
