Direct Admission from the Emergency Department to a Subacute Care Ward: An Alternative to Acute Hospitalization

Integrated care at the emergency department: an investment for better health

ABSTRACT

It is crucial that policy makers, healthcare providers and relevant stakeholders understand how integrated care may be improved at our emergency departments (EDs) and what benefits that would bring. The potential that exists for right-siting care of special patient groups who could be managed in an ambulatory setting with the integration of a variety of hospital-based and community-based clinical support services is tremendous. This review describes the best practice and value of integrated care at the EDs. Local evidence is cited and compared with findings from overseas. The opportunities of care transition interventions among discharged patients are outlined, including that for paediatric patients, palliative care patients and patients with chronic diseases. This review also suggests ways to move forward to meet the aim of providing holistic care at EDs through integrated care programmes, innovation and research.

Expanding the role of community hospitals to promote population health in Singapore

Population health encompasses health outcomes, their determinants, and the distribution within the group of individuals. A life course approach, involving residents regardless of health status and disease complexity, and addressing their needs holistically and contextually is a key policy for improving population health. Healthier SG represents Singapore's transformation towards population health. Under this initiative, Singapore's three healthcare clusters have been tasked with new roles as population health managers and regional health managers, on top of being healthcare service providers. We propose that beyond intermediate and post-acute care, community hospitals, as service providers, have an opportunity to (a) innovate new models of integrated and appropriate care, (b) adopt life-course approaches which include prevention and end-of-life care extended to community settings, (c) strengthen person-centred and holistic care approaches through social prescribing, (d) lead capability building and sector development for person-centred care, and (e) galvanize the health-social care ecosystem.

Transitional care strategies at emergency department for elderly patients: A multicentre study in Singapore

Introduction

Transitional care strategies (TCS) initiated for elderly patients prior to emergency department (ED) discharge are important for ensuring effective transition to other care settings. Such strategies have been shown to reduce avoidable acute admissions. This first nationwide study is targeted at public acute hospital EDs in Singapore, and aims to characterise TCS for ED-discharged elderly patients and understand the experiences of healthcare staff in the delivery of TCS.

Method

Seven key informants (KIs), one per ED, completed an online structured questionnaire and semi-structured video conference interview from 8 May to 31 August 2021. The KIs were ED specialists and an ED-trained senior staff nurse who were knowledgeable in geriatric emergency care and had contributed to at least one elder-related TCS. Field notes were compiled, transcribed, anonymised and analysed using thematic analysis.

Results

All 7 EDs have TCS as "usual care" available during office hours, at no extra cost to patients. Common components of TCS include screening, evaluation with comprehensive geriatric assessment, health education and follow-up telecare. TCS implementation was facilitated by organisational support in terms of established protocols and communication platforms, training and collaboration of a multidisciplinary team, and caregiver involvement. Obstacles faced include fragmented communication between personnel, limited resources, and poor buy-in from stakeholders.

Conclusion

Understanding the heterogeneous characteristics of ED-TCS at various hospitals will aid the development of service typology and identify service opportunities. Provider experiences grouped into themes help to inform future strategies for TCS implementation. More research is needed to evaluate patient outcomes and cost-effectiveness of TCS.

Impact of Geriatric Admissions on Workload in the Emergency Department

Background: Due to the increase in life expectancy, both the general population and the population of patients of emergency departments (ED) are getting older. An understanding of differences, workload and resource requirements may be helpful in improving patient care. The main goal of this study was to evaluate the reasons for geriatric admissions in the ED, identify typical medical problems and assess the number of resources in order to provide more effective management. Methods: We examined 35,720 elderly patients' ED visits over the course of 3 years. The data collected included age, sex, timing and length of stay (LOS), use of various resources, endpoint (admission, discharge or death) and ICD-10 diagnoses. Results: The median age was 73 years [66-81], with more females (54.86%). There were 57.66% elderly (G1), 36.44% senile (G2) and 5.89% long-liver (G3) patients. There were more females in the older groups. The total admission rate was 37.89% (34.19% for G1, 42.21% for G2 and 47.33% for G3). The average length of the patient's stay was 150 min [81-245] (G3 180 min [108-277], G2 (162 min [92-261]) and G1 139 min [71-230]). Heart failure, atrial fibrillation and hip fracture were the most common diagnoses. Nonspecific diagnoses were common in all groups. Conclusion: The vast majority of geriatric patients required considerable resources. With increasing ages, the number of women, LOS and number of admissions increased.

Realist analysis of streaming interventions in emergency departments

Background

Several of the many emergency department (ED) interventions intended to address the complex problem of (over)crowding are based on the principle of streaming: directing different groups of patients to different processes of care. Although the theoretical basis of streaming is robust, evidence on the effectiveness of these interventions remains inconclusive.

Methods

This qualitative research, grounded in the population-capacity-process model, sought to determine how, why and under what conditions streaming interventions may be effective. Data came from a broader study exploring patient flow strategies across Western Canada through in-depth interviews with managers at all levels. We undertook realist analysis of interview data from the 98 participants who discussed relevant interventions (fast-track/minor treatment areas, rapid assessment zones, diverse short-stay units), focusing on their explanations of initiatives’ perceived outcomes.

Results

Essential features of streaming interventions included separation of designated populations (population), provision of dedicated space and resources (capacity) and rapid cycle time (process). These features supported key mechanisms of impact: patients wait only for services they need; patient variability is reduced; lag time between steps is eliminated; and provider attitude change promotes prompt discharge. Conversely, reported failures usually involved neglect of one of these dimensions during intervention design and/or implementation. Participants also identified important contextual barriers to success, notably lack of outflow sites and demand outstripping capacity. Nonetheless, failure was more commonly attributed to intervention flaws than to context factors.

Conclusions

While streaming interventions have the potential to reduce crowding, a theory-based intervention relies on its implementers’ adherence to the theory. Streaming interventions cannot be expected to yield the desired results if operationalised in a manner incongruent with the theory on which they are supposedly based.

Can facility-based transitional care improve patient flow? Lessons from four Canadian regions

Units providing transitional, subacute, or restorative care represent a common intervention to facilitate patient flow and improve outcomes for lower acuity (often older) inpatients; however, little is known about Canadian health systems' experiences with such "transition units." This comparative case study of diverse units in four health regions (48 interviews) identified important success factors and pitfalls. A fundamental requirement for success is to clearly define the unit's intended population and design the model around its needs. Planners must also ensure that the unit be resourced and staffed to deliver truly restorative care. Finally, streamlined processes must be developed to help patients access and move through the unit. Units that were perceived as more effective appeared to have satisfactorily addressed these population, capacity, and process issues, whereas those perceived as less effective continued to struggle with them. Findings suggest principles to support optimal design and implementation of transition units.

Emergency Department Interventions for Frailty (EDIFY): Front-Door Geriatric Care Can Reduce Acute Admissions

OBJECTIVES

The EDIFY program was developed to deliver early geriatric specialist interventions at the emergency department (ED) to reduce the number of acute admissions by identifying patients for safe discharge or transfer to low-acuity care settings. We evaluated the effectiveness of EDIFY in reducing potentially avoidable acute admissions.

DESIGN

A quasi-experimental study.

SETTING

ED of a 1700-bed tertiary hospital.

PARTICIPANTS

ED patients aged ≥85 years.

MEASUREMENTS

We compared EDIFY interventions versus standard care. Patients with plans for acute admission were screened and recruited. Data on demographics, premorbid function, frailty status, comorbidities, and acute illness severity were gathered. We examined the primary outcome of "successful acute admission avoidance" among the intervention group, which was defined as no ED attendance within 72 hours of discharge from ED, no transfer to an acute ward from subacute-care units (SCU) within 72-hours, or no transfer to an acute ward from the short-stay unit (SSU). Secondary outcomes were rehospitalization, ED re-attendance, institutionalization, functional decline, mortality, and frailty transitions at 1, 3, and 6 months.

RESULTS

We recruited 100 participants (mean age 90.0 ± 4.1 years, 66.0% women). There were no differences in baseline characteristics between intervention (n = 43) and nonintervention (n = 57) groups. Thirty-five (81.4%) participants in the intervention group successfully avoided an acute admission (20.9% home, 23.3% SCU, and 44.2% SSU). All participants in the nonintervention group were hospitalized. There were no differences in rehospitalization, ED re-attendance, institutionalization and mortality over the study period. Additionally, we observed a higher rate of progression to a poorer frailty category at all time points among the nonintervention group (1, 3, and 6 months: all P < .05).

CONCLUSIONS AND IMPLICATIONS

Results from our single-center study suggest that early geriatric specialist interventions at the ED can reduce potentially avoidable acute admissions without escalating the risk of rehospitalization, ED re-attendance, or mortality, and with possible benefit in attenuating frailty progression.
