Functional and cognitive decline in older delirious adults after an emergency department visit

Entrusting life to professionals: A phenomenological hermeneutical study of older persons' participation in prehospital emergency care involving municipal home care and ambulance services

BACKGROUND

Participation in care is considered to promote safe and qualitative care. Care-dependent older persons ageing in place have increased emergency care needs, which initiate inter-organisational collaboration involving municipal home care and ambulance services. Previous research concludes that uncertainties exist regarding what participation in care means in clinical practice, which necessitates the need to illuminate the phenomenon for older persons in critical life situations.

AIM

This study aimed to illuminate meanings of participation in prehospital emergency care from the perspective of care-dependent older persons experiencing acute illness at home.

DESIGN

This study has a qualitative design with a lifeworld approach.

METHOD

A phenomenological hermeneutical method was used to analyse transcribed telephone interviews with eleven care-dependent persons aged 70-93 years.

RESULTS

Care-dependent older persons' participation in prehospital emergency care means 'Entrusting life to professional caregivers' when being in helpless solitude and existentially unsafe, which emphasises a deepened interpersonal dependence. Meanings of participation in care from the perspective of older persons involve Being reassured in togetherness, Being pliant in trust of emergency expertise, Being enabled through the agency of professional caregivers, and Encountering readiness in the emergency care chain.

CONCLUSION

Care-dependent older persons' participation in prehospital emergency care is existential and involves interpersonal dependence. Togetherness brings reassurance, safety and opportunity for emotional rest while accessing the professional caregivers' power, competence and abilities which provide opportunities for existence and movement towards well-being and continued living.

IMPLICATIONS FOR PRACTICE

Prehospital emergency care from the perspective of care-dependent older persons transcends organisational boundaries and includes the municipal mobile safety alarm service. The involved municipal and regional organisations need to provide support by implementing lifeworld-led care models and care alternatives that enable professionals to recognise the existential dimension of participation in care.

Identifying and predicting physical limitation and cognitive decline trajectory group of older adults in China: A data-driven machine learning analysis

OBJECTIVE

This study aimed to utilize data-driven machine learning methods to identify and predict potential physical and cognitive function trajectory groups of older adults and determine their crucial factors for promoting active ageing in China.

METHODS

Longitudinal data on 3026 older adults from the Chinese Longitudinal Healthy Longevity and Happy Family Survey was used to identify potential physical and cognitive function trajectory groups using a group-based multi-trajectory model (GBMTM). Predictors were selected from sociodemographic characteristics, lifestyle factors, and physical and mental conditions. The trajectory groups were predicted using data-driven machine learning models and dynamic nomogram. Model performance was evaluated by area under the receiver operating characteristics curve (AUROC), area under the precision-recall curve (PRAUC), and confusion matrix.

RESULTS

Two physical and cognitive function trajectory groups were determined, including a trajectory group with physical limitation and cognitive decline (14.18 %) and a normal trajectory group (85.82 %). Logistic regression performed well in predicting trajectory groups (AUROC = 0.881, PRAUC = 0.649). Older adults with lower baseline score of activities of daily living, older age, less frequent housework, and fewer actual teeth were more likely to experience physical limitation and cognitive decline trajectory group.

LIMITATION

This study didn't carry out external validation.

CONCLUSIONS

This study shows that GBMTM and machine learning models effectively identify and predict physical limitation and cognitive decline trajectory group. The identified predictors might be essential for developing targeted interventions to promote healthy ageing.

Nursing Home Residents With Dementia at End of Life: Emergency Department Visits, Hospitalizations, and Acute Hospital Deaths

Background: Most nursing home (NH) residents do not benefit from health care at an emergency room (ER) or inpatient care at an emergency hospital during the end-of-life period. Therefore, a low number of unplanned admissions during the last month of life are considered good quality of care. Objectives: This study examined ER visits, hospital admissions, and place of death in NH residents with and without dementia in the last month of life, with the aim of answering the question, "Are NH residents with dementia provided with equal health care in their last stage of life?" Design: An observational retrospective study of registry data from all NH residents who died during the years 2015-2019, using health care consumption data from the Stockholm Regional Council, Sweden. Results: Dementia was associated with a higher adjusted odds ratio (aOR) for ER visits (aOR 1.32, p < 0.0001) and acute admissions (aOR 1.30, p < 0.0001) (logistic regression, including sensitivity analysis). Being male, young, and having multiple comorbidities (Charlson Comorbidity Index) and frailty (Hospital Frailty Risk Score) were all independently associated with higher aORs for the same outcomes and also with hospital deaths. Conclusion: Dementia is associated with increased ER referrals and acute in-hospital care. Comorbidities and frailty were strongly associated with an increase in hospital deaths. In addition, men are sent to emergency hospitals more frequently than women, and older residents are sent to the hospital to a lesser extent than younger residents, which cannot be explained by the factors studied.

A Physiotherapy-Led Transition to Home Intervention for Older Adults Following Emergency Department Discharge: A Pilot Feasibility Randomised Controlled Trial (ED PLUS)

Background

Older adults frequently attend the emergency department (ED) and experience high rates of subsequent adverse outcomes including functional decline, ED re-presentation and unplanned hospital admission. The development of effective interventions to prevent such outcomes is a key priority for research and service provision. Our aim was to evaluate the feasibility of a physiotherapy-led integrated care intervention for older adults discharged from the ED (ED PLUS).

Patients and Methods

Older adults presenting to the ED of a university teaching hospital with undifferentiated medical complaints and discharged within 72 hours were computer randomised in a ratio of 1:1:1 to deliver usual care, Comprehensive Geriatric Assessment (CGA) in the ED, or ED PLUS. ED PLUS is an evidence-based and stakeholder-informed intervention to bridge the care transition between the ED and community by initiating a CGA in the ED and implementing a six-week, multi-component, self-management programme in the patient's home. Feasibility and acceptability were assessed quantitatively and qualitatively. All clinical and process outcomes were assessed by a research nurse blinded to group allocation. Data analyses were primarily descriptive.

Results

Twenty-nine participants were recruited indicating a 67% recruitment rate. At 6 months, there was 100% retention in the usual care group, 88% in the CGA group and 90% in the ED PLUS group. ED PLUS participants expressed positive feedback, and there was a trend towards improved function and quality of life and less ED revisits and unscheduled hospitalisations in the ED PLUS group.

Conclusion

ED PLUS bridges the transition of care between the index visit to the ED and the community and is feasible using systematic recruitment strategies. Despite recruitment challenges in the context of COVID-19, the intervention was successfully delivered and well received by participants. There was a lower incidence of functional decline and improved quality of life in the ED PLUS group.

Trial Registration

The trial was registered in Clinical Trials Protocols and Results System as of 21st July 2021, with registration number NCT04983602.

Establishing the core elements of a frailty at the front door model of care using a modified real-time Delphi technique

BACKGROUND

Innovations in models of care for older adults living with frailty presenting to the emergency department (ED) have become a key priority for clinicians, researchers and policymakers due to the deleterious outcomes older adults experience due to prolonged exposure to such an environment. This study aimed to develop a set of expert consensus-based statements underpinning operational design, outcome measurement and evaluation of a Frailty at the Front Door (FFD) model of care for older adults within an Irish context.

METHODS

A modified real-time Delphi method was used. Facilitation of World Café focus groups with an expert panel of 86 members and seperate advisory groups with a Public and Patient Involvement panel of older adults and members of the Irish Association of Emergency Medicine generated a series of statements on the core elements of the FFD model of care. Statements were analysed thematically and incorporated into a real-time Delphi survey, which was emailed to members of the expert panel. Members were asked to rank 70 statements across nine domains using a 9-point Likert scale. Consensus criteria were defined a priori and guided by previous research using 9-point rating scales.

RESULTS

Fifty members responded to the survey representing an overall response rate of 58%. Following analyses of the survey responses, the research team reviewed statements for content overlap and refined a final list of statements across the following domains: aims and objectives of the FFD model of care; target population; screening and assessment; interventions; technology; integration of care; evaluation and metrics; and research.

CONCLUSION

Development of a consensus derived FFD model of care represents an important step in generating national standards, implementation of a service model as intended and enhances opportunities for scientific impact. Future research should focus on the development of a core outcome set for studies involving older adults in the ED.

A rehabilitation intervention to improve recovery after an episode of delirium in adults over 65 years (RecoverED): study protocol for a multi-centre, single-arm feasibility study

BACKGROUND

Delirium affects over 20% of all hospitalised older adults. Delirium is associated with a number of adverse outcomes following hospital admission including cognitive decline, anxiety and depression, increased mortality and care needs. Previous research has addressed prevention of delirium in hospitals and care homes, and there are guidelines on short-term treatment of delirium during admission. However, no studies have addressed the problem of longer-term recovery after delirium and it is currently unknown whether interventions to improve recovery after delirium are effective and cost-effective. The primary objective of this feasibility study is to test a new, theory-informed rehabilitation intervention (RecoverED) in older adults delivered following a hospital admission complicated by delirium to determine whether (a) the intervention is acceptable to individuals with delirium and (b) a definitive trial and parallel economic evaluation of the intervention are feasible.

METHODS

The study is a multi-centre, single-arm feasibility study of a rehabilitation intervention with an embedded process evaluation. Sixty participants with delirium (aged > 65 years old) and carer pairs will be recruited from six NHS acute hospitals across the UK. All pairs will be offered the intervention, with follow-up assessments conducted at 3 months and 6 months post-discharge home. The intervention will be delivered in participants' own homes by therapists and rehabilitation support workers for up to 10 intervention sessions over 12 weeks. The intervention will be tailored to individual needs, and the chosen intervention plan and goals will be discussed and agreed with participants and carers. Quantitative data on reach, retention, fidelity and dose will be collected and summarised using descriptive statistics. The feasibility outcomes that will be used to determine whether the study meets the criteria for progression to a definitive randomised controlled trial (RCT) include recruitment, delivery of the intervention, retention, data collection and acceptability of outcome measures. Acceptability of the intervention will be assessed using in-depth, semi-structured qualitative interviews with participants and healthcare professionals.

DISCUSSION

Findings will inform the design of a pragmatic multi-centre RCT of the effectiveness and cost-effectiveness of the RecoverED intervention for helping the longer-term recovery of people with delirium compared to usual care.

TRIAL REGISTRATION

The feasibility study was registered: ISRCTN15676570.

Differential Effects of an Emergency Department-to-Home Care Transitions Intervention in an Older Adult Population: A Latent Class Analysis

BACKGROUND

Older adults frequently return to the emergency department (ED) within 30 days of a visit. High-risk patients can differentially benefit from transitional care interventions. Latent class analysis (LCA) is a model-based method used to segment the population and test intervention effects by subgroup.

OBJECTIVES

We aimed to identify latent classes within an older adult population from a randomized controlled trial evaluating the effectiveness of an ED-to-home transitional care program and test whether class membership modified the intervention effect.

RESEARCH DESIGN

Participants were randomized to receive the Care Transitions Intervention or usual care. Study staff collected outcomes data through medical record reviews and surveys. We performed LCA and logistic regression to evaluate the differential effects of the intervention by class membership.

SUBJECTS

Participants were ED patients (age 60 y and above) discharged to a community residence.

MEASURES

Indicator variables for the LCA included clinically available and patient-reported data from the initial ED visit. Our primary outcome was ED revisits within 30 days. Secondary outcomes included ED revisits within 14 days, outpatient follow-up within 7 and 30 days, and self-management behaviors.

RESULTS

We interpreted 6 latent classes in this study population. Classes 1, 4, 5, and 6 showed a reduction in ED revisit rates with the intervention; classes 2 and 3 showed an increase in ED revisit rates. In class 5, we found evidence that the intervention increased outpatient follow-up within 7 and 30 days (odds ratio: 1.81, 95% CI: 1.13-2.91; odds ratio: 2.24, 95% CI: 1.25-4.03).

CONCLUSIONS

Class membership modified the intervention effect. Population segmentation is an important step in evaluating a transitional care intervention.

"Older People Want to Be in Their Own Homes": A Service Evaluation of Patient and Carer Feedback after Pathfinder Responded to Their Emergency Calls

OBJECTIVE

Older people experience high rates of adverse outcomes following emergency department (ED) presentation. There is growing evidence to support alternative care pathways for certain types of emergency medical services (EMS) calls. Pathfinder is one such service and targets patients aged 65 years and over, whose presenting issues can be safely managed at home by immediate paramedic, occupational therapy, and/or physiotherapy interventions. The aim of this service evaluation was to understand how older people feel about being treated at home as a result of EMS calls and to understand their experiences of the Pathfinder service.

METHODS

This was a thematic analysis of open-ended responses recorded from telephone interviews during routine service evaluation with service users (patients or their next-of-kin).

RESULTS

Of 573 service users, telephone interviews were conducted with 429 (75%). Five primary themes were identified: (1) professionalism of the multidisciplinary clinical team; (2) "the right service, in the right place, at the right time"; (3) role of Pathfinder in "getting the ball rolling"; (4) lasting effects of the experience on the patient and his or her next-of-kin; (5) value of skilled communication with the older person.

CONCLUSION

Older people and their next-of-kin voiced a clear preference for hospital avoidance, and strongly valued the opportunity to be treated in their homes at the time of an EMS call rather than default conveyance to the ED. They appreciated the importance of a skilled multidisciplinary team with a follow-up service that effectively positions itself between the acute hospital and community services.

Can we improve delirium prevention and treatment in the emergency department? A systematic review

BACKGROUND

This systematic review was conducted to evaluate any interventions to prevent incident delirium, or shorten the duration of prevalent delirium, in older adults presenting to the emergency department (ED).

METHODS

Health sciences librarian designed electronic searches were conducted from database inception through September 2021. Two authors reviewed studies, and included studies that evaluated interventions for the prevention and/or treatment of delirium and excluded non-ED studies. The risk of bias (ROB) was evaluated by the Cochrane ROB tool or the Newcastle-Ottawa (NOS) scale. Meta-analysis was conducted to estimate a pooled effect of multifactorial programs on delirium prevention.

RESULTS

Our search strategy yielded 11,900 studies of which 10 met study inclusion criteria. Two RCTs evaluated pharmacologic interventions for delirium prevention; three non-RCTs employed a multi-factorial delirium prevention program; three non-RCTs evaluated regional anesthesia for hip fractures; and one study evaluated the use of Foley catheter, medication exposure, and risk of delirium. Only four studies demonstrated a significant impact on delirium incidence or duration of delirium-one RCT of melatonin reduced the incidence of delirium (OR 0.19, 95% CI 0.06 to 0.62), one non-RCT study on a multi-factorial program decreased inpatient delirium prevalence (41% to 19%) and the other reduced incident delirium (RR 0.37, 95% CI 0.22 to 0.61). One case-control study on the use of ED Foley catheters in the ED increased the duration of delirium (proportional OR 3.1, 95% CI 1.3 to 7.4). A pooled odds ratio for three multifactorial programs on delirium prevention was 0.46 (95% CI 0.31-0.68, I2  = 0).

CONCLUSION

Few interventions initiated in the ED were found to consistently reduce the incidence or duration of delirium. Delirium prevention and treatment trials in the ED are still rare and should be prioritized for future research.

Effectiveness of a care transitions intervention for older adults discharged home from the emergency department: A randomized controlled trial

BACKGROUND

Improving care transitions following emergency department (ED) visits may reduce post-ED adverse events among older adults (e.g., ED revisits, decreased function). The Care Transitions Intervention (CTI) improves hospital-to-home transitions; however, its effectiveness at improving post-ED outcomes is unknown. We tested the effectiveness of the CTI with community-dwelling older adult ED patients, hypothesizing that it would reduce revisits and increase performance of self-management behaviors during the 30 days following discharge.

METHODS

We conducted a randomized controlled trial among patients age ≥ 60 discharged home from one of three EDs in two states. Intervention participants received a minimally modified CTI, with a home visit 24 to 72 h postdischarge and one to three phone calls over 28 days. We collected demographic, health status, and psychosocial data at the initial ED visit. Medication adherence and knowledge of red flag symptoms were assessed via phone survey. Care use and comorbidities were abstracted from medical records. We performed multivariate regressions for intention-to-treat and per-protocol (PP) analyses.

RESULTS

Participant characteristics (N = 1,756) were similar across groups: mean age 72.4 ± 8.6 years and 53% female. Of those randomized to the intervention, 84% completed the home visit. Overall, 12.4% of participants returned to the ED within 30 days. The CTI did not significantly affect odds of 30-day ED revisits (adjusted odds ratio [AOR] = 0.97, 95% confidence interval [CI] = 0.72 to 1.30) or medication adherence (AOR = 0.89, 95% CI = 0.60 to 1.32). Participants receiving the CTI (PP) had increased odds of in-person follow-up with outpatient clinicians during the week following discharge (AOR = 1.24, 95% CI = 1.01 to 1.51) and recalling at least one red flag from ED discharge instructions (AOR = 1.34 95% CI = 1.05 to 1.71).

CONCLUSIONS

The CTI did not reduce 30-day ED revisits but did significantly increase key care transition behaviors (outpatient follow-up, red flag knowledge). Additional research is needed to explore if patients with different conditions benefit more from the CTI and whether decreasing ED revisits is the most appropriate outcome for all older adults.
