The impact of a new emergency admission avoidance system for older people on length of stay and same-day discharges

Impact of a geriatric intervention based on the Comprehensive Geriatrics Assessment on avoidable admissions in older patients at risk evaluated in the Emergency Department

OBJECTIVE

To know the impact of a geriatric intervention based on the Comprehensive Geriatric Assessment (CGA) on avoidable admissions in older patients at risk evaluated in the Emergency Department.

METHOD

Prospective observational unicenter study. We included patients, from October 1, 2018 to January 31, 2020, over 75 years who were attended at the Emergency Department with a Triage Risk Screening Tool (TRST) score≥2. All patients were evaluated by a geriatrician through the CGA. The reasons for going to the Emergency room were collected and also the main intervention carried out by Geriatrics, whether admission or discharge was indicated and whether the admission was avoidable. We did a cost analysis calculating this by (bed/day×average stay×number of admissions avoided).

RESULTS

We included 260 patients, 66% were women and the mean age was 86 years. 73.5% patients had polypharmacy, the mean Charlson index was 2.5 (5.6). 63.3% were independent for walking and 20.8% independent for basic activities of daily living. 59% had cognitive impairment. 91.5% lived at home. The most frequent reason for visiting the Emergency room was decline of general state in 22% and the most frequent intervention carried out by Geriatrics was assistance in the decision making process in 35.4% followed by referral to a preferential outpatient geriatric care circuit in 32.7%. Other interventions carried out by Geriatrics was assistance in clarifying diagnosis (4.2%), assistance in pharmacological adjustment (8.5%), referral to a standard geriatric care pathway (13.1%), telephone follow-up (4.2%) and/or coordination with Social Services for care planning (11.2%). Including all patients, 29.2% required hospital admission and 70.8% were discharged. 40% admissions were avoided, which meant more than 540 thousand euros saved.

CONCLUSIONS

A standardized CGA coordinated by Geriatrics in older patients at risk of suffering adverse events in the Emergency room reduces admissions and costs, so it should therefore be established as a recommendation of good clinical practice.

An emergency department transitional care team prevents unnecessary hospitalization of older adults: a mixed methods study

INTRODUCTION

Older adults with acute functional decline may visit emergency departments (EDs) for medical support despite a lack of strict medical urgency. The introduction of transitional care teams (TCT) at the ED has shown promise in reducing avoidable admittances. However, the optimal composition and implementation of TCTs are still poorly defined. We evaluated the effect of TCTs consisting of an elderly care physician (ECP) and transfer nurse versus a transfer nurse only on reducing hospital admissions, as well as the experience of patients and caregivers regarding quality of care.

METHODS

We assessed older adults (≥ 65 years) at the ED with acute functional decline but no medical indication for admission. Data were collected on type and post-ED care, and re-visits were evaluated over a 30-day follow-up period. Semi-structured interviews with stakeholders were based on the Consolidated-Framework-for-Implementation-Research, while patient and caregiver experiences were collected through open-ended interviews.

RESULTS

Among older adults (N = 821) evaluated by the TCT, ECP and transfer nurse prevented unnecessary hospitalization at the same rate (81.2%) versus a transfer nurse alone (79.5%). ED re-visits were 15.6% (ECP and transfer nurse) versus 13.5%. The interviews highlighted the added value of an ECP, which consisted of better staff awareness, knowledge transfer and networking with external organizations. The TCT intervention in general was broadly supported, but adaptability was regarded as an important prerequisite.

CONCLUSION

Regardless of composition, a TCT can prevent unnecessary hospitalization of older adults without increasing ED re-visiting rates, while the addition of an ECP has a favourable impact on patient and professional experiences.

Impact of the geriatric emergency medicine specialist intervention on final emergency department disposition

BACKGROUND

The Geriatric Emergency Medicine Specialist (GEMS) pilot program is an innovative approach that utilizes geriatric-trained advanced practice providers to facilitate geriatric assessments and care planning for older adults in the emergency department (ED). The objective of this study was to explore the effect of GEMS on the use of observation status and final ED disposition.

METHODS

This was a retrospective study under a target trial emulation framework. Geriatric patients (65+ years old) who presented to two ED sites within a large regional healthcare system between December 2020 and December 2022 were included. The primary outcome was final ED disposition (discharge, hospital inpatient admission, or hospital observation admission). Secondary outcomes included ED observation and ED length of stay. Non-GEMS patients were propensity score matched 5:1 to GEMS patients. Doubly robust regression was used to estimate the odds ratios and 95% confidence intervals of inpatient admission, discharge, hospital observation admission, ED observation admission, and estimate the mean ED length of stay.

RESULTS

A total of 427 of 43,064 total patients (1.0%) received a GEMS intervention during the study period. Our analysis included 2,302 geriatric ED patients (410 GEMS, 1,892 non-GEMS) after propensity score matching. Hospital admission rates were 34.1% for GEMS compared to 56.4% for conventional treatment. GEMS patients had decreased odds of inpatient admission (OR: 0.41, 95 CI: 0.34-0.51, p < 0.001), increased odds of discharge (OR: 1.19 95 CI: 1.00-1.42, p = 0.047), hospital observation admission (OR: 2.97, 95 CI: 2.35-3.75, p < 0.001), ED observation admission (OR: 4.84 95 CI: 3.67-6.38, p < 0.001), and had a longer average ED length of stay (170 min, 95 CI: 84.6-256, p < 0.001) compared to non-GEMS patients.

CONCLUSIONS

Patients seen by GEMS during their ED visit were associated with higher rates of hospital discharge and lower rates of hospital admissions.

Strategies to improve care for older adults who present to the emergency department: a systematic review

BACKGROUND

The aim of this systematic review was to examine the relationship between strategies to improve care delivery for older adults in ED and evaluation measures of patient outcomes, patient experience, staff experience, and system performance.

METHODS

A systematic review of English language studies published since inception to December 2022, available from CINAHL, Embase, Medline, and Scopus was conducted. Studies were reviewed by pairs of independent reviewers and included if they met the following criteria: participant mean age of ≥ 65 years; ED setting or directly influenced provision of care in the ED; reported on improvement interventions and strategies; reported patient outcomes, patient experience, staff experience, or system performance. The methodological quality of the studies was assessed by pairs of independent reviewers using The Joanna Briggs Institute critical appraisal tools. Data were synthesised using a hermeneutic approach.

RESULTS

Seventy-six studies were included in the review, incorporating strategies for comprehensive assessment and multi-faceted care (n = 32), targeted care such as management of falls risk, functional decline, or pain management (n = 27), medication safety (n = 5), and trauma care (n = 12). We found a misalignment between comprehensive care delivered in ED for older adults and ED performance measures oriented to rapid assessment and referral. Eight (10.4%) studies reported patient experience and five (6.5%) reported staff experience.

CONCLUSION

It is crucial that future strategies to improve care delivery in ED align the needs of older adults with the purpose of the ED system to ensure sustainable improvement effort and critical functioning of the ED as an interdependent component of the health system. Staff and patient input at the design stage may advance prioritisation of higher-impact interventions aligned with the pace of change and illuminate experience measures. More consistent reporting of interventions would inform important contextual factors and allow for replication.

Clinical and financial outcome impacts of comprehensive geriatric assessment in a level 1 geriatric emergency department

BACKGROUND

The aging population has led to an increase in emergency department (ED) visits by older adults who have complex medical conditions and high social needs. The purpose of this study was to assess if comprehensive geriatric evaluation and management impacted service utilization and cost by older adults admitted to the ED.

METHODS

This is a retrospective matched case-control study at a level 1 geriatric ED (GED) from January 1, 2018-March 31, 2020. Geriatric nurse specialists (GENIEs) provided comprehensive evaluations and management for GED patients. Propensity score matching was used to match patients receiving GENIE consultations to ED patients who did not receive a GENIE consult. Regression was used to assess the impact of the GENIE services on inpatient admissions, ED revisits and cost of inpatient and ED care from the payor perspective.

RESULTS

GENIE consults were associated with a 13.0% reduction in absolute risk of admission through the ED at index (95% confidence interval [CI] -17.0%, -9.0%, p < 0.001) and a reduction in risk for total admissions at 30 and 90-days post discharge (-11.3%, 95% CI -15.6%, -7.1%, p-value < 0.001; and -10.0, 95% CI -13.8%, -6.0%; p < 0.001 respectively), both driven by reduced risk of admission at the index visit. GENIE consults were associated with a 4% increase in absolute risk of revisits to the ED within 30 days (95% CI 0.6%, 7.3%; p = 0.001). GENIE consults were associated with a decrease in cost of inpatient and ED care, with savings of $2344 within 30 days (95% CI $2247, $2441, p < 0.001) and savings of $2004 USD within 90 days (95% CI $1895, $2114, p < 0.001), driven by reduced costs at the index visit.

CONCLUSIONS

GENIE consults were associated with decreased inpatient admissions through the ED, modestly increased ED revisits, and decreased cost of inpatient and ED care. The results of this study can be useful for EDs considering approaches to better serve older adults. They can also be of interest to payers as an area of potential cost savings.

Association of Geriatric Emergency Department post-discharge referral order and follow-up with healthcare utilization

BACKGROUND

Compared with younger adults who receive care in the emergency department (ED), older patients who are discharged home have greater risk of adverse health outcomes. Connecting older adults with outpatient care following ED discharge are among the guidelines of the Geriatric Emergency Department (GED). The objective of this study was to examine the association between referral order placed during the ED visit for older adults and post-discharge follow-up to the outcomes of 72-h ED revisit, 30-day ED revisit, and 30-day all cause and unplanned hospital admission.

METHODS

We conducted a retrospective cohort study. Ten accredited GEDs within one midwestern health system and all ED encounters of older adults aged 65 years and older who were discharged home from the ED between July 2019 and December 2020 were included. Predictor variables included age, sex, race, ISAR©, ED Length of Stay, post-ED referral order, and follow-up.

RESULTS

Among the older adults discharged home from the ED, 17% of older adult encounters had an outpatient referral ordered in the ED, 48.4% attended a follow-up appointment. Referrals were ordered for 69 referral order types with orthopedic, family practice, and urology referrals as the top 3. In mixed-effect regression models, compared with older adults with follow-up, those with a referral order but no follow-up had 19% higher odds of having a 30-day ED revisit (OR = 1.19; 95% CI = 1.07-1.31) and 11% higher odds of having 30-day unplanned hospital admission (OR = 1.11; 95% CI = 0.98-1.26).

CONCLUSIONS

Older adults who had an outpatient referral ordered prior to ED discharge and followed up had lower odds of a 30-day ED revisit and 30-day subsequent unplanned hospital admission. However, less than half of patients with a referral order attended a follow-up appointment. Designing interventions for older adults aimed at improving follow-up after an ED visit is needed.

Care experiences of older people with mental health needs and their families in emergency medical services settings

BACKGROUND

There are challenges to person-centred care provision in Emergency Medical Services (EMS) settings. The environment is often busy and noisy which can influence the experience of older people and their carer/partners when they attend emergency departments. Older people with mental health needs are a vulnerable group of people who are at risk of not having their needs met in acute care settings. This is due to complex presentations and increased pressures on the EMS system.

AIM

The aim of the paper was to explore the care experience of older people with mental health needs and their carer/partners in pre-hospital and in-hospital Emergency Medical Services settings.

METHOD

This study used an interpretive qualitative approach incorporating in-depth, individual interviews to gather information on the experience of the older person with mental health needs and carers/partners. Data were analysed using Braun and Clarke's (2006) thematic analysis.

RESULTS

Fifteen individual interviews were carried out with older people with mental health needs (n = 10) and with carers/partners (n = 5). Six themes on 'Getting there, getting in and getting out', 'Seeing the person', 'Perceptions and experiences of the pre-hospital and Emergency Department (ED)', 'The effects of the experience on personal well-being', 'Older person/carer/partner perceptions and experiences of the EMS staff' and 'Making it better' emerged from the data.

CONCLUSIONS

The results suggest that previous experiences with the emergency care system influence the way older people with mental health needs and their carers make decisions on current and future care needs. Negative experiences can be influenced by the layout and organisation of the ED. Participants remain reluctant to discuss or disclose their diagnosis in the Emergency Medical Services setting due to a perceived stigma. Health and social care systems and services need to undergo transformations to ensure that all people who access services are treated fairly and effectively.

Is There Evidence of an Association Between Acute Health Care Utilization and Function in Older Adults Over Time? A Population-Based Cohort Study

Background and Objectives

Acute health care use varies by age, with older adults the highest users of acute health care services. Using data from The Irish Longitudinal Study on Ageing (TILDA), the aim of this study was to investigate the association between acute health care utilization (emergency department [ED] visit with or without hospitalization) at baseline and subjective and objective measures of function measured at 4-year follow-up.

Research Design and Methods

This study represents a secondary analysis of a prospective cohort study, where data from Wave 1 (baseline) and Wave 3 of TILDA were analyzed in conjunction with a public and patient involvement group of older adults. Acute health care utilization was defined as an ED visit with or without hospitalization in the previous 12 months. Function was assessed objectively using the Timed Up and Go (TUG) test and a measure of grip strength, and subjectively using self-report limitations in activities of daily living (ADL) and instrumental ADL (IADL).

Results

A total of 1 516 participants met the study inclusion criteria. Mean age was 70.9 ± 4.6 years and 48% were male. At baseline, 1 280 participants reported no acute health care use. One hundred and eighteen indicated an ED visit but no hospitalization in the previous 12 months and 118 reported both an ED visit and hospitalization. Adjusting for all covariates, compared to those with no acute health care utilization, those with an ED visit with no hospital admission had poorer TUG performance at follow-up (β = 0.67, 95% confidence interval: 0.34, 1.29, p = .039).

Discussion and Implications

This paper supports previous research that acute health care events, specifically ED usage, are associated with reduced function for older adults as assessed by TUG at follow-up. No associations were observed for grip strength, ADL, or IADL. Further research is required in this area, exploring ED visits and the possible benefits of evaluating older adults at this stage.

Association of age with emergency department visits and hospital admissions: A nationwide study

AIM

Older adults are frequently stigmatized for improper emergency department (ED) visits and hospitalizations. In this study, we aimed to investigate the relationship between age and appropriateness of ED visits, and the mismatching between ED clinical severity and hospitalizations.

METHODS

We carried out a nationwide assessment of Italian Informative System for the Emergency and Urgency data from 1 January 2015 to 31 December 2015 including patients admitted to all the Italian EDs for any reason. Appropriateness of ED visits was defined as a yellow/red/black color code (potentially life-threatening/dead patients), whereas clinical severity/hospitalization mismatching was defined as hospital admission after validated ED green/white codes. Analyses dedicated to people aged ≥75 years were carried out.

RESULTS

There were 20 400 071 ED visits (3 444 091 aged ≥75 years), which increased with age, up to >650/1000 inhabitants aged ≥90 years. The appropriateness of ED visits increased with age, from 6.3% in the 5-9 years age group to 44.2% in the 95-99 years age group. Clinical severity/hospitalization mismatching decreased with age, from 62.9% in the 30-34 years age group to 27.7% in the 95-99 years age group. At ED presentation, 21.6% of patients aged ≥75 years complained of non-specific symptoms, and hospital discharge diagnoses frequently differed from the ED admission diagnoses; 11.4% died during hospitalization and 8.8% were discharged to long-term care facilities.

CONCLUSIONS

The request for ED care and the admission to acute care ward are commonly appropriate for older patients. Clinical presentation at ED admission is frequently atypical. Health care systems should aim at improving outpatients' management to reduce the ED care need, but also at optimizing in-hospital strategies and pathways for older adults.

Urgent care for older people

Geriatric medicine is the clinical specialty that focuses upon the care of older people-especially those with frailty (a state of increased vulnerability). In hospital, older people living with frailty are at high risk of developing a range of unpleasant outcomes such as delirium, falls, fractures, pressure sores and death. Comprehensive geriatric assessment is a form of holistic care that incorporates a specific set of clinical competencies that are able to reduce these adverse outcomes. Over the years, geriatric medicine has moved from being more of a community-based service towards a more acute specialty-encroaching now upon emergency department care. The challenge now is to work out how best to deliver geriatric care across the whole hospital (older people with frailty are not just cared for in geriatric wards!). The themed collection published on the Age & Ageing journal website outlines key articles that are attempting to develop solutions to this challenging conundrum. We hope that you enjoy reading them.

Association between emergency department length of stay and patient outcomes: A systematic review

In this review, we investigate associations between time spent in the emergency department (ED) and patient reported outcomes. ED staff provide initial assessment, treatment and referral to patients presenting with an acute status to the hospital 24 h a day. ED length of stay, including ED boarding, and treatment received in the ED may affect patient outcomes. In this review we considered published studies that explored the association of ED length of stay of individuals of any age with their subsequent outcomes, including mortality and inpatient length of stay (IPLOS). Joanna Briggs Institute methods for systematic reviews of association were followed. Search strategies were developed to identify studies published in English since 2000 for inclusion. Two reviewers assessed the studies for inclusion and methodological quality and extracted data independently. In total, 34 studies were included in the review, including one case-control, one analytical cross-sectional, and 32 retrospective cohort studies, with a total sample size of 2,308,840 patients. Overall, there were variable associations of time spent in the ED and mortality, IPLOS, time-to-treatment and adverse events. However, findings indicated that older people are at risk for longer ED stays. They may also experience higher mortality. Specific focus should be placed upon elderly people in the ED, to reduce their exposure to the ED environment where possible and to implement focused initiatives that address their specific and complex treatment needs. We conclude that the diversity of individual settings and health systems will require locally defined and relevant solutions to locally identified issues.

Systematic geriatric assessment for older patients with frailty in the emergency department: a randomised controlled trial

BACKGROUND

Comprehensive geriatric assessment provided in hospital wards in frail patients admitted to hospital has been shown to reduce mortality and increase the likelihood of living at home later. Systematic geriatric assessment provided in emergency departments (ED) may be effective for reducing days in hospital and unnecessary hospital admissions, but this has not yet been proven in randomised trials.

METHODS

We conducted a single-centre, randomised controlled trial with a parallel-group, superiority design in an academic hospital ED. ED patients aged ≥ 75 years who were frail, or at risk of frailty, as defined by the Clinical Frailty Scale, were included in the trial. Patients were recruited during the period between December 11, 2018 and June 7, 2019, and followed up for 365 days. For the intervention group, systematic geriatric assessment was added to their standard care in the ED, whereas the control group received standard care only. The primary outcome was cumulative hospital stay during 365-day follow-up. The secondary outcomes included: admission rate from the index visit, total hospital admissions, ED-readmissions, proportion of patients living at home at 365 days, 365-day mortality, and fall-related ED-visits.

RESULTS

A total of 432 patients, 63 % female, with median age of 85 years, formed the analytic sample of 213 patients in the intervention group and 219 patients in the control group. Cumulative hospital stay during one-year follow-up as rate per 100 person-years for the intervention and control groups were: 3470 and 3149 days, respectively, with rate ratio of 1.10 (95 % confidence interval, 0.55-2.19, P = .78). Admission rates to hospital wards from the index ED visit for the intervention and control groups were: 62 and 70 %, respectively (P = .10). No significant differences were observed between the groups for any outcomes.

CONCLUSION

Systematic geriatric assessment for older adults with frailty in the ED did not reduce hospital stay during one-year follow-up. No statistically significant difference was observed for any secondary outcomes. More coordinated, continuous interventions should be tested for potential benefits in long-term outcomes.

TRIAL REGISTRATION

The trial was registered in the ClinicalTrials.gov (registration number and date NCT03751319 23/11/2018).

Effectiveness of a Geriatric Emergency Medicine Unit for the Management of Neurocognitive Disorders in Older Patients: Results of the MUPACog Study

INTRODUCTION

The prevalence of neurocognitive disorders (NCDs) increases with age and is associated with cognitive impairment. Older patients with NCD admitted to the emergency department (ED) are readmitted after discharge to home more often than those without NCD. Comprehensive geriatric assessment (CGA) is effective for improving clinical outcomes in older patients; however, the usefulness of CGA for older patients with NCD admitted to the ED has not been investigated. The main objective of our study is to assess the effectiveness of a geriatric emergency medicine unit (GEMU) for elderly patients with NCD admitted to the ED.

METHODS

This historical cohort study included patients aged 75 years and older with NCD admitted to the ED of Limoges University Hospital in France over a 4-year period. We compared patients treated in our hospital's GEMU, the MUPA unit (exposed group), and patients who received standard care by emergency physicians (control group). The primary end point was the incidence of 30-day readmissions.

RESULTS

The study included 801 patients admitted to the ED between January 1, 2015, and December 31, 2018 (400 in the exposed group). Of those, 72.5% were female, and the mean age was 87 ± 5 years. After adjusting for confounding factors, the 30-day readmission rate was significantly associated with the MUPA unit intervention.

CONCLUSION

CGA in a GEMU improved health outcomes in elderly patients with NCD in the ED. We recommend that all EDs include a geriatric team, such as the MUPA unit, to treat all patients with NCD admitted to the ED.

Improving before-noon discharges in the acute medical ward

Background:

Mismatch in admission and discharge rates with poor coordination of bed availability to prepare for peak admission time do not favor patient flow in any healthcare situation. In order to meet the admissions demand from the emergency department, early discharge is advocated.

Aim:

The purpose of this study was to increase the 11:30 discharge rate in the acute medical ward to 20% within 5 months in order to facilitate patient transfers from the emergency department.

Method and intervention:

A nurse-led multidisciplinary team discussion at 10:00 was formed empowering nurses and aims to prioritize early discharges or transfer patients who require a longer stay in the hospital. The indication of expected discharge date was determined by team doctors on either day 1 or 2 of admission, to facilitate and prioritize allied health intervention or even prescription processing. Physical transfer to the discharge lounge was to occur earlier, awaiting preparation of prescription and documentation. Dedicated nursing staff who manage the discharge lounge processes, were to ensure the transfers and care arrangements to be smooth and coordinated with enhanced communication to next of kin.

Results:

The overall median rate for discharges before 11:30 in the acute medical ward was at 17%, compared to baseline median discharge rate of 12% ( p=0.05) and evening discharges that remained. With the implementation of a framework for multidisciplinary team discussion, the mean time spent on multidisciplinary team reduced to 40 min from the pre-intervention stage, ranging approximately 57–68 min.

Conclusion:

The discharge process is complex and requires multidisciplinary team collaboration and coordination. This project also created an opportunity for more relevant project targeting evening discharges that addresses another emergency department peak admission time.

Association of a Geriatric Emergency Department Innovation Program With Cost Outcomes Among Medicare Beneficiaries

IMPORTANCE

There has been a significant increase in the implementation and dissemination of geriatric emergency department (GED) programs. Understanding the costs associated with patient care would yield insight into the direct financial value for patients, hospitals, health systems, and payers.

OBJECTIVE

To evaluate the association of GED programs with Medicare costs per beneficiary.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional study included data on Medicare fee-for-service beneficiaries at 2 hospitals implementing Geriatric Emergency Department Innovations in Care Through Workforce, Informatics, and Structural Enhancement (GEDI WISE) (Mount Sinai Medical Center [MSMC] and Northwestern Memorial Hospital [NMH]) from January 1, 2013, to November 30, 2016. Analyses were conducted and refined from August 28, 2018, to November 20, 2020, using entropy balance to account for observed differences between the treatment and comparison groups.

INTERVENTIONS

Treatment included consultation with a transitional care nurse (TCN) or a social worker (SW) trained for the GEDI WISE program at a beneficiary's first ED visit (index ED visit). The comparison group included beneficiaries who were never seen by either a TCN or an SW during the study period.

MAIN OUTCOMES AND MEASURES

The main outcome evaluated was prorated total Medicare payer expenditures per beneficiary over 30 and 60 days after the index ED visit encounter.

RESULTS

Of the total 24 839 unique Medicare beneficiaries, 4041 were seen across the 2 EDs; 1947 (17.4%) at MSMC and 2094 (15.4%) at the NMH received treatment from either a GED TCN and/or a GED SW. The mean (SD) age of beneficiaries at MSMC was 78.8 (8.5) years and at NMH was 76.4 (7.7) years. Most patients at both hospitals were female (6821 [60.8%] at MSMC and 8023 [58.9%] at NMH) and White (7729 [68.9%] at MSMC and 9984 [73.3%] at NMH). Treatment was associated with statistically significant mean savings per beneficiary of $2436 (95% CI, $1760-$3111; P < .001) at one ED and $2905 (95% CI, $2378-$3431; P < .001) at the other ED in the 30 days after the index ED visit. The association between treatment and mean cumulative savings at 60 days after the index ED visit per beneficiary was also significant: $1200 (95% CI, $231-$2169; P = .02) at one ED and $3202 (95% CI, $2452-$3951; P < .001) at the other ED.

CONCLUSIONS AND RELEVANCE

Among Medicare fee-for-service beneficiaries, receipt of ED-based geriatric treatment by a TCN and/or an SW was associated with lower Medicare expenditures. These estimated cost savings may be used when calculating or considering the bundled value and potential reimbursement per patient for GED care programs.

Can dedicated emergency team and area for older people reduce the hospital admission rate? - An observational pre- and post-intervention study

BACKGROUND

Emergency department (ED) care of older patients is often complex. Geriatric ED guidelines can help to meet this challenge. However, training requirements, the use of time-consuming tools for comprehensive geriatric assessment (CGA), a lack of golden standard to identify the frail patients, and the weak evidence of positive outcomes of using CGA in EDs pose barriers to introduce the guidelines. Dedicating an interprofessional team of regular ED medical and nursing staff and an older-friendly ED area can be another approach. Previous studies of geriatrician-led CGA in EDs have reported a reduced hospital admission rate. The aim of this study was to investigate whether a dedicated interprofessional emergency team also can reduce the hospital admission rate without the resources required by the formal use of CGA.

METHODS

An observational pre-post study at a large adult ED, where all patients 80 years or older arriving on weekdays in the intervention period from 2016.09.26 to 2016.11.28 and the corresponding weekdays in the previous year from 2015.09.28 to 2015.11.30 were included. In the intervention period, older patients either received care in the geriatric module by the dedicated team or in the regular team modules for patients of mixed ages. In 2015, all patients received care in regular team modules. The primary outcome measure was the total hospital admission rate and the ED length of stay was the secondary outcome measure.

RESULTS

We included 2377 arrivals in the intervention period, when 26.7% (N = 634) received care in the geriatric module, and 2207 arrivals in the 2015 period. The total hospital admission rate was 61.7% (N = 1466/2377) in the intervention period compared to 64.8% (N = 1431/2207) in 2015 (p = 0.03). The difference was larger for patients treated in the geriatric module, 51.1% compared to 62.1% (95% CI: 56.3 to 68.0%) for patients who would have been eligible in 2015. The ED length of stay was longer in the intervention period.

CONCLUSIONS

An interprofessional team and area dedicated to older patients was associated to a lower hospital admission rate. Further studies are needed to confirm the results.

The Whittington Frailty Pathway: improving access to comprehensive geriatric assessment: an interdisciplinary quality improvement project

National guidelines mandate identification and tailored management of patients living with frailty who attend the acute hospital setting. We describe using quality improvement (QI) techniques to embed a system that allowed identification of frailty in older patients attending the emergency department (ED), creation of a clinical pathway to facilitate comprehensive geriatric assessment and appropriate same-day discharge of suitable patients. Integration of Clinical Frailty Scale (CFS) scoring within an electronic record system, a continuing programme of education and awareness, and dedicated project staff allows patients to be identified for an ambulatory frailty pathway. Our results show a sustained improvement over 9 months of the project, with 73% of patients over the age of 75 years presenting to ED by ambulance now receiving a CFS score. Over 300 patients have been identified, transferred to ambulatory care and treated via a new frailty pathway, with an admission rate for this cohort of 14%, compared with an overall admission rate of 50% for patients over 75 years. We report a decrease in overall ED admission of 1%. Analysis of patients discharged through this same-day pathway showed a 7-day ED reattendance rate of 15.1% and a 30-day readmission rate of 18.9%, which are comparable with current pathways. Consultant review estimated 87% of patients to have avoided a longer admission. Patient and staff satisfaction indicates this pathway to be feasible and acceptable to users. Our data suggest an ambulatory frailty pathway can deliver significant admission avoidance while maintaining low readmission rates. Similar schemes in other hospitals should consider using QI approaches to implementation of frailty pathways.

Multidisciplinary interventions for reducing the avoidable displacement from home of frail older people: a systematic review

OBJECTIVES

To synthesise existing literature on interventions addressing a new concept of avoidable displacement from home for older people with multimorbidity or frailty. The review focused on home-based interventions by any type of multidisciplinary team aimed at reducing avoidable displacement from home to hospital settings. A second objective was to characterise these interventions to inform policy.

DESIGN

A systematic search of the main bibliographic databases was conducted to identify studies relating to interventions addressing avoidable displacement from home for older people. Studies focusing on one specific condition or interventions without multidisciplinary teams were excluded. A narrative synthesis of data was conducted, and themes were identified by using an adapted thematic framework analysis approach.

RESULTS

The search strategy was performed using the following electronic databases: the American National Library of Medicine and the National Institutes of Health (PubMed), Scopus, Cochrane Library (Central and CDRS), CINAHL, Social Care Online, Web of Science as well as the database of the Latin American and Caribbean Health Sciences Literature. The database search was done in September 2018 and completed in October 2018. Overall 3927 articles were identified and 364 were retained for full text screening. Fifteen studies were included in the narrative review. Four themes were identified and discussed: (1) types of interventions, (2) composition of teams, (3) intervention effectiveness and (4) types of outcomes. Within intervention types, three categories of care types were identified; transitional care, case-management services and hospital at home. Each individual article was assessed in terms of risk of bias following Cochrane Collaboration guidelines.

CONCLUSIONS

The review identified some potential interventions and relevant topics to be addressed in order to develop effective and sustainable interventions to reduce the avoidable displacement from home of older people. However the review was not able to identify robust impact evidence, either in terms of quantity or quality from the studies presented. As such, the available evidence is not sufficiently robust to inform policy or interventions for reducing avoidable displacement from home. This finding reflects the complexity of these interventions and a lack of systematic data collection.

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

BACKGROUND

URGENT 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.

METHODS

A 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.

RESULTS

Almost 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).

CONCLUSIONS

The 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.

The Geriatric Emergency Department Intervention model of care: a pragmatic trial

BACKGROUND

To evaluate a Geriatric Emergency Department Intervention (GEDI) model of service delivery for adults aged 70 years and older.

METHODS

A pragmatic trial of the GEDI model using a pre-post design. GEDI is a nurse-led, physician-championed, Emergency Department (ED) intervention; developed to improve the care of frail older adults in the ED. The nurses had gerontology experience and education and provided targeted geriatric assessment and streamlining of care. The final format included 2.4 full time equivalent nurses working 7 days from 0700 h to 1730 h (1530 h at weekends). There were three implementations periods: pre-implementation (2012); a developmental phase from January 2013 to August 2015; and full implementation from September 2015 to August 2016. The outcomes measured were disposition (discharged home, admitted or died); ED length of stay; hospital length of stay; all cause in-hospital mortality within 28 days; time to ED re-presentation up to 28 days post-discharge; in-hospital costs. The setting was a tertiary hospital ED, with 385 beds, in Queensland, Australia. Approximately 53,000 patients presented to the ED annually with 20% aged 70 years and older. All patients over the age 70 who presented to the ED between January 2012 and August 2016 (n = 44,983) were included in the trial.

RESULTS

Older persons who presented to the ED when the GEDI team were working had increased likelihoods of discharge (Hazard ratio (HR) = 1.19; 95% CI: 1.13-1.24) and reduced ED length of stay (HR = 1.42; 95% CI: 1.33-1.52) compared with those who presented when GEDI were not working. There was no increase in the risk of mortality (HR = 1.01; 95% CI = 0.23-4.43) or risk of same cause re-presentation to 28 days (HR = 1.21; 95% CI: 0.99-1.49). The GEDI service resulted in average cost savings per ED presentation of $35 [95% CI, $21, $49] and savings of $1469 [95% CI, $1105, $1834] per hospital admission.

CONCLUSIONS

Implementation of a nurse-led physician-championed model of ED care, focused on frail older adults, reduced ED length of stay, hospital admission and if admitted, hospital length of stay and cost, without increasing mortality or same cause re-presentation. These increases were sustained over time and after the initial implementation team had changed roles.

Risk Factors and Outcomes of Delirium in Older Patients Admitted to Postacute Care with and without Dementia

BACKGROUND

Delirium research is poorly studied in postacute care, a growing setting due to aging populations, as well as in dementia, a critical risk factor for delirium and particularly prevalent in postacute care. We investigated risk factors for delirium and its outcomes in older adults with and without dementia admitted to a subacute care unit (SCU) after exacerbated chronic conditions.

METHODS

This is a prospective cohort study including patients ≥65 years old admitted to an SCU for 12 months. We collected demographics, comprehensive geriatric assessments, and presence of dementia and delirium at admission. Outcomes included discharge to previous living situation, mortality, and functional evolution. Due to the high prevalence of dementia, a subgroup analysis was performed to investigate specific risk factors for delirium and related outcomes.

RESULTS

Of 909 patients (mean age [±SD] 85.8 ± 6.7; 60% women, 47.5% with dementia), 352 (38.7%) developed delirium. The main risk factor for delirium was dementia (HR [95% CI] 5.2 [3.5-7.7]); age, functional status, and urinary tract infections were also independently associated with delirium. In dementia patients, only age (HR [95% CI] 1.0 [1.004-1.1]) and being male (HR [95% CI] 1.7 [1.04-2.6]) were associated with delirium. Delirium was associated with greater mortality (10.8 vs. 3.9%; p < 0.001) and greater functional decline in the entire sample (-12.3 vs. -6.4 Barthel index points; p < 0.001). In the dementia subgroup, patients with delirium experienced greater functional loss (p = 0.013) and less functional recovery (p = 0.025).

CONCLUSIONS

In older patients admitted to postacute care, dementia is the main risk factor for delirium, and delirium carries worse clinical and functional outcomes. In patients with dementia, delirium is also relevant, since it entails a functional loss at admission and lower functional recovery.

Nurse-led multidisciplinary initiatives to improve outcomes and reduce hospital admissions for older adults: The Care coordination through Emergency Department, Residential Aged Care and Primary Health Collaboration project

OBJECTIVES

This article describes the Care coordination through Emergency Department, Residential Aged Care and Primary Health Collaboration (CEDRiC) project.

METHODS

CEDRiC is designed to improve the health outcomes for older people with an acute illness. It attempts this via enhanced primary care in residential aged care facilities, focused and streamlined care in the emergency department and enhanced intersectoral communication and referral.

RESULTS

Implementing this approach has the potential to decrease inappropriate hospital admissions while improving care for older people in residential aged care and community settings.

CONCLUSION

This article discusses an innovative way of caring for older adults in an ageing population utilising the existing evidence. A formal evaluation is currently underway.

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.

The Reshaping Care for Older People programme and changes in unscheduled hospital care: Analysis of routinely collected hospital data

OBJECTIVE

This study examines mean length of stay (LOS) and rates of emergency bed days during the course of the Reshaping Care for Older People (RCOP) programme in Glasgow City.

METHODS

An ecological small-area study design was used. Standardised monthly rates of bed days and LOS were calculated, between April 2011 and March 2015, for residents of Glasgow City aged 65 years and over. Multilevel negative binomial models for the square root of each outcome nested by datazone were created, adjusting for sex, 5-year age group, area-level deprivation, season, month and month squared. Relative index of inequality (RII) and slope index of inequality (SII) were calculated for each year and the trend was examined.

RESULTS

The rate of bed days first rose then fell during the study period, while LOS first fell then rose. Relative risk (RR) of an additional bed day was greater for males (RR=1.14 (1.12, 1.16)) and increased with increasing age group. There was no gender difference in LOS. Bed days per head of population first increased then fell; for 12-month period RR=1.01 (0.98, 1.05) and for 12-month period squared, RR=0.999 (0.999, 0.999). RII and SII for rate of bed days per head of population were significant, though not for LOS. SII for bed days per head of population did not change significantly over time, while RII reduced at the 87% level of confidence.

CONCLUSIONS

The results suggest a reduction in secondary care use by older people during the RCOP programme, and a possible reduction in socioeconomic inequalities in bed days in the longer term.

Frailty identification in the emergency department-a systematic review focussing on feasibility

Introduction

risk-stratifying older people accessing urgent care is a potentially useful first step to ensuring that the most vulnerable are able to access optimal care from the start of the episode. While there are many risk-stratification tools reported in the literature, few have addressed the practical issues of implementation. This review sought evidence about the feasibility of risk stratification for older people with urgent care needs.

Methods

medline was searched for papers addressing risk stratification and implementation (feasibility or evaluation or clinician acceptability). All search stages were conducted by two reviewers, and selected papers were graded for quality using the CASP tool for cohort studies. Data were summarised using descriptive statistics only.

Results

about 1872 titles of potential interest were identified, of which 1827 were excluded on title/abstract review, and a further 43 after full-text review, leaving four papers for analysis. These papers described nine tools, which took between 1 and 10 minutes to complete for most participants. No more than 52% of potentially eligible older people were actually screened using any of the tools. Little detail was reported on the clinical acceptability of the tools tested.

Discussion

the existing literature indicates that commonly used risk-stratification tools are relatively quick to use, but do not cover much more than 50% of the potential population eligible for screening in practice. Additional work is required to appreciate how tools are likely to be used, by whom, and when in order to ensure that they are acceptable to urgent care teams.

Geriatric support in the emergency department: a national survey in Belgium

Background

Older people in the emergency department (ED) represent a growing population and increasing proportion of the workload in the ED. This study investigated the support for frail older people in the ED, by exploring the collaboration between the geriatric services (GS) and the EDs in Belgian hospitals.

Methods

An electronic cross-sectional survey in all Belgian hospitals with an ED (n = 100) about care aspects, collaboration, education and infrastructure for older patients in the ED was collected. Descriptive analyses were performed at national level.

Results

Forty-nine of 100 surveys were completed by the GS. The heads of the ED returned only 12 incomplete questionnaires and these results are therefore not reported.

Twenty-six of the 49 heads of GSs (53%) indicated that there was an agreement, mainly informal, between the geriatric and the emergency department concerning the management of older people on the ED.

A geriatrician was available for specific problems, by phone or in person, in 96% of the EDs during daytime on weekdays. Almost all responding hospitals (96%) had an inpatient geriatric consultation team, of which 85% was available for specific problems at the ED, by phone or bedside during the daytime on weekdays. Twenty-nine heads of the GSs (59%) reported that older patients were screened at ED admission during the day to identify ‘at risk’ patients. The results of the screening were used in the context of further treatment (76%), to decide on hospital admission (27%), or to justify admission on a geriatric ward (55%). In the year preceding the survey, 25% of the responding hospitals had organised geriatric training for ED healthcare workers. Thirty-four heads of the GS (69%) felt that the infrastructure of the ED was insufficient to give high-quality care for older persons.

Conclusion

Collaborations between EDs and GS are emerging in Belgium, but are currently rather limited and not yet sufficiently embedded in the ED care. Exploratory studies are necessary to identify how these collaborations can be improved.

Impact of an integrated medicines management service on preventable medicines-related readmission to hospital: a descriptive study

Background

Medication contributes to 5-20% of hospital admissions, of which half are considered preventable. An integrated medicines management service (IMMS) was developed at a large general hospital in London to identify and manage patients at risk of a preventable medicines-related readmission (PMRR) to reduce the risk of PMRR.

Objective

To investigate the effect of the pharmacy IMMS on the rate of PMRR within 30 days of the first discharge.

Method

744 patients were identified between October 2008 and October 2014, using the PREVENT tool. Patients at risk were managed by the IMMS with medication reconciliation, review, consultation and follow-up, as required.

Results

Of 744 patients, 119 were readmitted within 30 days of discharge, with a PMRR for 2 patients (1.7%). The main reason for referral to the service was to assess the need to start a compliance aid. Most interventions involved communication: 84% included patient consultations with 50% involving discussion with the patient's community pharmacist and 32% with their general practitioner surgery.

Conclusions

An IMMS may be an effective method of reducing the rate of PMRR. Further work is needed to establish the cost-effectiveness of the service.

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.

Does the get up and go test improve predictive accuracy of the Triage Risk Screening Tool or Rowland questionnaire in older patients admitted to the emergency department?

OBJECTIVES

To assess the diagnostic characteristics of the get up and go test (GUGT) as a stand-alone test and in combination with the Flemish Triage Risk Screening Tool (fTRST) and Rowland questionnaire. One aim was to determine whether the diagnostic accuracy of these instruments could be improved for predicting unplanned emergency department (ED) readmission following ED discharge.

METHODS

We carried out a prospective cohort study at the ED of the University Hospitals Leuven, Belgium. All patients aged at least 75 years (n=380) completed fTRST, Rowland, and GUGT testing at the index ED admission. Diagnostic characteristics for unplanned ED readmission were determined for hospitalized and discharged patients 1 and 3 months after the index ED visit.

RESULTS

In both hospitalized and discharged patients, fTRST and Rowland (cut-off ≥2) had good to excellent sensitivity and negative predictive value (NPV) but low to moderate specificity and accuracy; GUGT had low sensitivity and good to excellent NPV and specificity. The combined fTRST/GUGT or Rowland/GUGT had moderate to excellent NPV (56.3-94.3%). The combined fTRST (cut-off ≥2)/GUGT had low sensitivity and moderate to excellent specificity. Sensitivity of the combined Rowland (cut-off ≥4)/GUGT was good at the 1-month follow-up and moderate at the 3-month follow-up for hospitalized patients; it was low for discharged patients. Specificity was low for hospitalized patients and good for discharged patients.

CONCLUSION

Neither the objective measure of mobility (GUGT) nor the combined fTRST/GUGT or Rowland/GUGT improved the results. Our analysis shows that the predictive accuracy of the stand-alone, self-reported screening instruments fTRST and Rowland (cut-off=2) is still good. This study also confirmed their previously known limitations.

Characteristics of Older Adults Admitted to Hospital versus Those Discharged Home, in Emergency Department Patients Referred to Internal Medicine

Background

Frail older adults present to the Emergency Department (ED) with complex medical, functional, and social needs. When these needs can be addressed promptly, discharge is possible, and when they cannot, hospital admission is required. We evaluated the care needs of frail older adults in the ED who were consulted to internal medicine and seen by a geriatrician to determine, under current practices, which factors were associated with hospitalization and which allowed discharge.

Methods

We preformed a chart-based, exploratory study. Data were abstracted from consultation records and ED charts. All cases had a standard Comprehensive Geriatric Assessment (CGA which records a Clinical Frailty Scale (CFA) and allows calculation of a Frailty Index (FI).

Results

Of 100 consecutive patients, 2 died in the ED, 75 were admitted, and 23 were discharged, including one urgent placement. Compared with discharged patients (0.39 ± SD 0.16), those admitted had a higher mean FI-CGA (0.48 ± 0.13; p < .01). Greater mobility dependence (2% in discharged vs. 32% in admitted; p < .05) was notable.

Conclusions

Discharge decisions require assessment of medical, functional, and social problems. Ill, frail patients often can be discharged home when social and nursing support can be provided. The degree of frailty, impaired mobility, and likely delirium must be taken into account when planning for their care.

How can frontline expertise and new models of care best contribute to safely reducing avoidable acute admissions? A mixed-methods study of four acute hospitals

Background

Hospital emergency admissions have risen annually, exacerbating pressures on emergency departments (EDs) and acute medical units. These pressures have an adverse impact on patient experience and potentially lead to suboptimal clinical decision-making. In response, a variety of innovations have been developed, but whether or not these reduce inappropriate admissions or improve patient and clinician experience is largely unknown.

Aims

To investigate the interplay of service factors influencing decision-making about emergency admissions, and to understand how the medical assessment process is experienced by patients, carers and practitioners.

Methods

The project used a multiple case study design for a mixed-methods analysis of decision-making about admissions in four acute hospitals. The primary research comprised two parts: value stream mapping to measure time spent by practitioners on key activities in 108 patient pathways, including an embedded study of cost; and an ethnographic study incorporating data from 65 patients, 30 carers and 282 practitioners of different specialties and levels. Additional data were collected through a clinical panel, learning sets, stakeholder workshops, reading groups and review of site data and documentation. We used a realist synthesis approach to integrate findings from all sources.

Findings

Patients’ experiences of emergency care were positive and they often did not raise concerns, whereas carers were more vocal. Staff’s focus on patient flow sometimes limited time for basic care, optimal communication and shared decision-making. Practitioners admitted or discharged few patients during the first hour, but decision-making increased rapidly towards the 4-hour target. Overall, patients’ journey times were similar, although waiting before being seen, for tests or after admission decisions, varied considerably. The meaning of what constituted an ‘admission’ varied across sites and sometimes within a site. Medical and social complexity, targets and ‘bed pressure’, patient safety and risk, each influenced admission/discharge decision-making. Each site responded to these pressures with different initiatives designed to expedite appropriate decision-making. New ways of using hospital ‘space’ were identified. Clinical decision units and observation wards allow potentially dischargeable patients with medical and/or social complexity to be ‘off the clock’, allowing time for tests, observation or safe discharge. New teams supported admission avoidance: an acute general practitioner service filtered patients prior to arrival; discharge teams linked with community services; specialist teams for the elderly facilitated outpatient treatment. Senior doctors had a range of roles: evaluating complex patients, advising and training juniors, and overseeing ED activity.

Conclusions

This research shows how hospitals under pressure manage complexity, safety and risk in emergency care by developing ‘ground-up’ initiatives that facilitate timely, appropriate and safe decision-making, and alternative care pathways for lower-risk, ambulatory patients. New teams and ‘off the clock’ spaces contribute to safely reducing avoidable admissions; frontline expertise brings value not only by placing senior experienced practitioners at the front door of EDs, but also by using seniors in advisory roles. Although the principal limitation of this research is its observational design, so that causation cannot be inferred, its strength is hypothesis generation. Further research should test whether or not the service and care innovations identified here can improve patient experience of acute care and safely reduce avoidable admissions.

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.

Hospital readmissions in frail older people

The majority of hospital in-patients are older people, and many of these are at increased risk of readmission, which can be an adverse outcome for the patient. Currently there is poor understanding as to how best to reduce the risk of readmission. We searched MEDLINE, EMBASE and the Cochrane library for high quality review articles about readmissions. Each review was quality assessed by two reviewers. Grouped data and evidence from original papers is cited with 95% confidence intervals when possible. Nine review studies of sufficient quality were included. Two addressed risk factors for readmission, which included: age, poor functional status prior to admission, length of stay during the index admission, depression, cognitive impairment, malnutrition, social support and social networks/support. The seven other reviews addressed interventions to reduce readmission, which included: discharge planning, post-discharge support, post-discharge case management, and nutritional supplementation. It is possible to identify older people at risk of readmission using well-established risk factors; discharge planning, post-discharge support and nutritional interventions appear to be effective in reducing readmission. Combined interventions appear to be more effective than isolated interventions.

The influence of an intermediate care hospital on health care utilization among elderly patients--a retrospective comparative cohort study

BACKGROUND

An intermediate care hospital (ICH) was established in a municipality in Central Norway in 2007 to improve the coordination of services and follow-up among elderly and chronically ill patients after hospital discharge. The aim of this study was to compare health care utilization by elderly patients in a municipality with an ICH to that of elderly patients in a municipality without an ICH.

METHODS

This study was a retrospective comparative cohort study of all hospitalized patients aged 60 years or older in two municipalities. The data were collected from the national register of hospital use from 2005 to 2012, and from the local general hospital and two primary health care service providers from 2008 to 2012 (approx. 1,250 patients per follow-up year). The data were analyzed using descriptive statistics and analysis of covariance (ANCOVA).

RESULTS

The length of hospital stay decreased from the time the ICH was introduced and remained between 10% and 22% lower than the length of hospital stay in the comparative municipality for the next five years. No differences in the number of readmissions or admissions during one year follow-up after the index stay at the local general hospital or changes in primary health care utilization were observed. In the year after hospital discharge, the municipality with an ICH offered more hour-based care to elderly patients living at home (estimated mean = 234 [95% CI 215-252] versus 175 [95% CI 154-196] hours per person and year), while the comparative municipality had a higher utilization of long-term stays in nursing homes (estimated mean = 33.3 [95% CI 29.0-37.7] versus 21.9 [95% CI 18.0-25.7] days per person and year).

CONCLUSIONS

This study indicates that the introduction of an ICH rapidly reduces the length of hospital stay without exposing patients to an increased health risk. The ICH appears to operate as an extension of the general hospital, with only a minor impact on the pattern of primary health care utilization.

Comprehensive geriatric assessment in the emergency department

Changing global demography is resulting in older people presenting to emergency departments (EDs) in greater numbers than ever before. They present with greater urgency and are more likely to be admitted to hospital or re-attend and utilize greater resources. They experience longer waits for care and are less likely to be satisfied with their experiences. Not only that, but older people suffer poorer health outcomes after ED attendance, with higher mortality rates and greater dependence in activities of daily living or rates of admission to nursing homes. Older people's assessment and management in the ED can be complex, time consuming, and require specialist skills. The interplay of multiple comorbidities and functional decline result in the complex state of frailty that can predispose to poor health outcomes and greater care needs. Older people with frailty may present to services in an atypical fashion requiring detailed, multidimensional, and increasingly multidisciplinary care to provide the correct diagnosis and management as well as appropriate placement for ongoing care or admission avoidance. Specific challenges such as delirium, functional decline, or carer strain need to be screened for and managed appropriately. Identifying patients with specific frailty syndromes can be critical to identifying those at highest risk of poor outcomes and most likely to benefit from further specialist interventions. Models of care are evolving that aim to deliver multidimensional assessment and management by multidisciplinary specialist care teams (comprehensive geriatric assessment). Increasingly, these models are demonstrating improved outcomes, including admission avoidance or reduced death and dependence. Delivering this in the ED is an evolving area of practice that adapts the principles of geriatric medicine for the urgent-care environment.
