The Increasing Geriatric Population and Overcrowding in the Emergency Department: One Hospital’s Approach

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.

Impact of population ageing on growing demand for emergency transportation to emergency departments in Western Australia, 2005-2020

OBJECTIVE

The aim of the present paper is to quantify the impact of population ageing on demand for emergency transportation (ET) to EDs in Western Australia (WA).

METHODS

A population-based longitudinal study using the statewide ED presentation data from 2005-2014 was used to predict ET demand in 2020, stratified by age group and sex.

RESULTS

From 2005 to 2014, 14.9% of all ED presentations arrived by ET. The number rose from 94 369 (13.9%) in 2005 to 153 374 (15.5%) in 2014, a compound annual growth of 5.5%. Of those presentations, 55.2% resulted in hospital admission. The proportion was higher in older age groups (64.5% in 65-74 years, 67.1% in 75-84 years and 68.4% in ≥85 years). Of ED presentations arriving by ET in age group ≥65 years, 70.9% were Australasian Triage Scale category 1, 2 or 3. The rate of ET per 1000 population increased in all age groups and sex. The highest growth was in the older age groups: from 86.6, 187.0 and 512.1 in ages 65-74 years, 75-84 years and ≥85 years, respectively, in 2005 to 102.5, 226.7 and 613.6 in 2014, and are expected to increase to 115.1, 264.3 and 707.7 by 2020. The ET demands in these age groups were projected to increase annually by 5.0%, 3.6% and 4.9%, respectively, in the next 6 years, comparing to less than 4.5% in the younger age groups.

CONCLUSION

There has been a continuous rise in ET demand in WA, particularly in older people who have a higher urgency and requirement for admission.

Content Validation of a Novel Screening Tool to Identify Emergency Department Patients With Significant Palliative Care Needs

BACKGROUND

The emergency department (ED) is increasingly used by patients with life-limiting illness. These patients are frequently admitted to the hospital, where they suffer from poorly controlled symptoms and are often subjected to marginally effective therapies. Palliative care (PC) has emerged as the specialty that cares for patients with advanced illness. PC has been shown to reduce symptoms, improve quality of life, and decrease resource utilization. Unfortunately, most patients who could benefit from PC are never identified. At present, there exists no validated screening tool to identify significant unmet PC needs among ED patients with life-limiting illness.

OBJECTIVES

The objective was to develop a simple, content-valid screening tool for use by ED providers to identify ED patients with significant PC needs. A positive screen would result in an inpatient PC consultation.

METHODS

An initial screening tool was developed based on a critical review of the literature. Content validity was determined by a two-round modified Delphi technique using a panel of PC experts. The expert panel reviewed the items of the tool for accuracy and necessity using a Likert scale and provided narrative feedback. Expert's responses were aggregated and analyzed to revise the tool until consensus was achieved. Greater than 80% agreement, as well as meeting Lawshe's critical values, was required to achieve consensus.

RESULTS

Fifteen experts completed two rounds of surveys to reach consensus on the content validity of the tool. Three screening items were accepted with minimal revisions. The remaining items were revised, condensed, or eliminated. The final tool contains 13 items divided into three steps: 1) presence of a life-limiting illness, 2) unmet PC needs, and 3) hospital admission. The majority of panelists (86%) endorsed adoption of the final screening tool.

CONCLUSIONS

Use of a modified Delphi technique resulted in the creation of a content-validated screening tool for identification of ED patients with significant unmet PC needs. Further validation testing of the instrument is warranted.
