Implementation of an emergency department observation unit for elderly adults in a university-affiliated hospital in Spain: a 6-year analysis of data

Study protocol for IMAGE: implementing multidisciplinary assessments for geriatric patients in an emergency department observation unit, a hybrid effectiveness/implementation study using the Consolidated Framework for Implementation Research

BACKGROUND

Older adults in the emergency department (ED) are at high risk for functional decline, unrecognized delirium, falls, and medication interactions. Holistic assessment by a multidisciplinary team in the ED decreases these adverse outcomes and decreases admissions, but there are many barriers to incorporating this type of care during the ED visit.

METHODS

This is a hybrid type II effectiveness-implementation study using a pre-/post-cohort design (n = 380) at a tertiary care academic ED with an ED observation unit (Obs Unit). The intervention is a two-step protocol of (step 1) ED nurses screening adult patients ≥ 65 years old for geriatric needs using the Delirium Triage Screen, 4-Stage Balance Test, and the Identifying Seniors at Risk score. Patients who have geriatric needs identified by this screening but who do not meet hospital admission criteria will (step 2) be placed in the Obs Unit for multidisciplinary geriatric assessment by the hospital's geriatric consultation team, physical therapists, occupational therapists, pharmacists, and/or case managers. Not all patients may require all elements of the multidisciplinary geriatric assessment. The Consolidated Framework for Implementation Research: Care Transitions Framework was used to identify barriers to implementation. Lean Six Sigma processes will be used to overcome these identified barriers with the goal of achieving geriatric screening rates of > 80%. Implementation success and associated factors will be reported. For the effectiveness aim, pre-/post-cohorts of adults ≥ 65 years old cared for in the Obs Unit will be followed for 90 days post-ED visit (n = 150 pre and 230 post). The primary outcome is the prevention of functional decline. Secondary outcomes include health-related quality of life, new geriatric syndromes identified, new services provided, and Obs Unit metrics such as length of stay and admission rates.

DISCUSSION

A protocol for implementing integrated multidisciplinary geriatric assessment into the ED setting has the potential to improve patient functional status by identifying and addressing geriatric issues and needs prior to discharge from the ED. Using validated frameworks and implementation strategies will increase our understanding of how to improve the quality of ED care for older adults in the acute care setting.

Concepts in Practice: Geriatric Emergency Departments

In 2018, the American College of Emergency Physicians (ACEP) began accrediting facilities as "geriatric emergency departments" (EDs) according to adherence to the multiorganizational guidelines published in 2014. The guidelines were developed to help every ED improve its care of older adults. The geriatric ED guideline recommendations span the care continuum from out-of-hospital care, ED staffing, protocols, infrastructure, and transitions to outpatient care. Hospitals interested in making their EDs more geriatric friendly thus face the challenge of adopting, adapting, and implementing extensive guideline recommendations in a cost-effective manner and within the capabilities of their facilities and staff. Because all innovation is at heart local and must function within the constraints of local resources, different hospital systems have developed implementation processes for the geriatric ED guidelines according to their differing institutional capabilities and resources. This article describes 4 geriatric ED models of care to provide practical examples and guidance for institutions considering developing geriatric EDs: a geriatric ED-specific unit, geriatrics practitioner models, geriatric champions, and geriatric-focused observation units. The advantages and limitations of each model are compared and examples of specific institutions and their operational metrics are provided.

A National Dataset Analysis of older adults in emergency department observation units

BACKGROUND

Emergency Department (ED) Observation Units (Obs Units) are prevalent in the US, but little is known regarding older adults in observation. Our objective was to describe the Obs Units nationally and observation patients with specific attention to differences in care with increasing age.

DESIGN

This is an analysis of 2010-2013 data from the National Hospital Ambulatory Medical Care Survey (NHAMCS), a national observational cohort study including ED patients. Weighted means are presented for continuous data and weighted percent for categorical data. Multivariable logistic regression was used to identify variables associated with placement in and admission from observation.

RESULTS

The number of adult ED visits varied from 100 million to 107 million per year and 2.3% of patients were placed in observation. Adults ≥65 years old made up a disproportionate number of Obs Unit patients, 30.6%, compared to only 19.7% of total ED visits (odds ratio 1.5 (95% CI 1.5-1.6), adjusting for sex, race, month, day of week, payer source, and hospital region). The overall admission rate from observation was 35.6%, ranging from 31.3% for ages 18-64 years to 47.5% for adults ≥85 years old (p < 0.001). General symptoms (e.g., nausea, dizziness) and hypertensive disease were the most common diagnoses overall. Older adults varied from younger adults in that they were frequently observed for diseases of the urinary system (ICD-9 590-599) and metabolic disorders (ICD-9 270-279).

CONCLUSIONS

Older adults are more likely to be cared for in Obs Units. Older adults are treated for different medical conditions than younger adults.

What evidence is there for the identification and management of frail older people in the emergency department? A systematic mapping review

Background

Emergency departments (EDs) are facing unprecedented levels of demand. One of the causes of this increased demand is the ageing population. Older people represent a particular challenge to the ED as those older people who are frail will require management that considers their frailty alongside their presenting complaint. How to identify these older people as frail and how best to manage them in the ED is a major challenge for the health service to address.

Objectives

To systematically map interventions to identify frail and high-risk older people in the ED and interventions to manage older people in the ED and to map the outcomes of these interventions and examine whether or not there is any evidence of the impact of these interventions on patient and health service outcomes.

Design

A systematic mapping review.

Setting

Evidence from developed countries on interventions delivered in the ED.

Participants

Frail and high-risk older people and general populations of older people (aged > 65 years).

Interventions

Interventions to identify older people who are frail or who are at high risk of adverse outcomes and to manage (frail) older people within the ED.

Main outcome measures

Patient outcomes (direct and indirect) and health service outcomes.

Data sources

Evidence from 103 peer-reviewed articles and conference abstracts and 17 systematic reviews published from 2005 to 2016.

Review methods

A review protocol was drawn up and a systematic database search was undertaken for the years 2005–2016 (using MEDLINE, EMBASE, The Cochrane Library, Web of Science, Cumulative Index to Nursing and Allied Health Literature, Health Management Information Consortium and PROSPERO). Studies were included according to predefined criteria. Following data extraction, evidence was classified into interventions relating to the identification of frail/high-risk older people in the ED and interventions relating to their management. A narrative synthesis of interventions/outcomes relating to these categories was undertaken. A quality assessment of individual studies was not undertaken; instead, an assessment of the overall evidence base in this area was made.

Results

Of the 90 included studies, 32 focused on a frail/high-risk population and 60 focused on an older population. These studies reported on interventions to identify (n = 57) and manage (n = 53) older people. The interventions to identify frail and at-risk older people, on admission and at discharge, utilised a number of different tools. There was extensive evidence on these question-based tools, but the evidence was inconclusive and contradictory. Service delivery innovations comprised changes to staffing, infrastructure and care delivery. There was a general trend towards improved outcomes in admissions avoidance, reduced ED reattendance and improved discharge outcomes.

Limitations

This review was a systematic mapping review. Some of the methods adopted differed from those used in a standard systematic review. Mapping the evidence base has led to the inclusion of a wide variety of evidence (in terms of study type and reporting quality). No recommendations on the effectiveness of specific interventions have been made as this was outside the scope of the review.

Conclusions

A substantial body of evidence on interventions for frail and high-risk older people was identified and mapped.

Future work

Future work in this area needs to determine why interventions work and whether or not they are feasible for the NHS and acceptable to patients.

New horizons: urgent care for older people with frailty

Urgent care for older people is a major public health issue and attracts much policy attention. Despite many efforts to curb demand, many older people with frailty and urgent care needs to access acute hospital services. The predominant model of care delivered in acute hospitals tends to be medically focussed, yet the evidence-based approaches that appear to be effective invoke a holistic model of care, delivered by interdisciplinary teams embedding geriatric competencies into their service. This article reviews the role for holistic care-termed Comprehensive Geriatric Assessment in the research literature-and how it can be used as an organising framework to guide future iterations of acute services to be better able to meet the multifaceted needs of older people.

Establishing and implementing best practice to reduce unplanned admissions in those aged 85 years and over through system change [Establishing System Change for Admissions of People 85+ (ESCAPE 85+)]: a mixed-methods case study approach

Background

In England, between 2007/8 and 2009/10, the rate of unplanned hospital admissions of people aged 85 years and above rose from 48 to 52 per 100. There was substantial variation, with some areas showing a much faster rate of increase and others showing a decline.

Objectives

To identify system characteristics associated with higher and lower increases in unplanned admission rates in those aged 85 years and over; to develop recommendations to inform providers and commissioners; and to investigate the challenges of starting to implement these recommendations.

Design

Mixed-methods study using routinely collected data, in-depth interviews and focus groups. Data were analysed using the framework approach, with themes following McKinsey’s 7S model. Recommendations derived from our findings were refined and prioritised through respondent validation and consultation with the project steering group. The process of beginning to implement these recommendations was examined in one ‘implementation site’.

Participants

Six study sites were selected based on admission data for patients aged 85 years and above from primary care trusts: three where rates of increase were among the most rapid and three where they had slowed down or declined. Each ‘improving’ or ‘deteriorating’ site comprised an acute hospital trust, its linked primary care trust/clinical commissioning group, the provider of community health services, and adult social care. At each site, representatives from these organisations at strategic and operational levels, as well as representatives of patient groups, were interviewed to understand how policies had been developed and implemented. A total of 142 respondents were interviewed.

Results

Between 2007/8 and 2009/10, average admission rates for people aged 85 years and over rose by 5.5% annually in deteriorating sites and fell by 1% annually in improving sites. During the period under examination, the population aged 85 years and over in deteriorating sites increased by 3.4%, compared with 1.3% in improving sites. In deteriorating sites, there were problems with general practitioner access, pressures on emergency departments and a lack of community-based alternatives to admission. However, the most striking difference between improving and deteriorating sites was not the presence or absence of specific services, but the extent to which integration within and between types of service had been achieved. There were also overwhelming differences in leadership, culture and strategic development at the system level. The final list of recommendations emphasises the importance of issues such as maximising integration of services, strategic leadership and adopting a system-wide approach to reconfiguration.

Conclusions

Rising admission rates for older people were seen in places where several parts of the system were under strain. Places which had stemmed the rising tide of admissions had done so through strong, stable leadership, a shared vision and strategy, and common values across the system.

Future work

Research on individual components of care for older people needs to take account of their impact on the system as a whole. Areas where more evidence is needed include the impact of improving access and continuity in primary care, the optimal capacity for intermediate care and how the frail elderly can best be managed in emergency departments.
