Hospital Elder Life Program: Systematic Review and Meta-analysis of Effectiveness

Predisposing and precipitating factors for delirium in neurology: a prospective cohort study of 1487 patients

INTRODUCTION

Predisposing and precipitating factors for delirium are well known; however, their interaction and impact on delirium in neurological patients remains largely unknown. Therefore, those factors were evaluated in hospitalized patients with neurological disorders.

METHODS

In this prospective cohort study, 1487 neurological patients were included, 356 patients with delirium and 1131 without delirium. Relevant neurological- and medical-related clusters were assessed with multiple regression analyses, prediction models, and cluster analysis evaluating their association with delirium.

RESULTS

The 1-year incidence of delirium in this cohort was 23.9%. Delirium developed in 31% of patients with stroke, in 39.5% with epilepsy, and in 58.4% with ICH. The most relevant predisposing factors were substance-use disorders (OR 4.24, 2.28-7.78, p < 0.001), advanced age (OR 3.44, CI 2.40-4.92, p < 0.001), and neurodegenerative disorders (OR 2.58, CI 1.47-4.54, p = 0.001). The most relevant precipitating factors were meningitis (OR 21.52, CI 1.22-379.83, p = 0.036), acute renal failure (OR 10.01, CI 1.13-88.73, p = 0.039), and intracranial hemorrhage (OR 3.62, CI 2.08-6.30, p < 0.001). Delirious patients were hospitalized 6 days longer, had higher in-hospital mortality, and were discharged more often to nursing homes and rehabilitation. Best predictor for delirium was the coexistence of advanced age with epilepsy (58.3%, p < 0.001), while patients aged < 65 years without epilepsy and stroke rarely developed delirium (5.1%, p < 0.001).

CONCLUSIONS

Delirium is common in elder neurological patients and associated with worse outcome. Primary cerebral conditions most frequently precipitate delirium in neurology. Neurologists are advised to monitor symptoms of delirium in the presence of risk factors to enable both timely diagnostic work-up and management of delirium.

An interdisciplinary statement of scientific societies for the advancement of delirium care across Europe (EDA, EANS, EUGMS, COTEC, IPTOP/WCPT)

Background

Delirium is a geriatric syndrome that presents in 1 out of 5 hospitalized older patients. It is also common in the community, in hospices, and in nursing homes. Delirium prevalence varies according to clinical setting, with rates of under 5% in minor elective surgery but up to 80% in intensive care unit patients. Delirium has severe adverse consequences, but despite this and its high prevalence, it remains undetected in the majority of cases. Optimal delirium care requires an interdisciplinary, multi-dimensional diagnostic and therapeutic approach involving doctors, nurses, physiotherapists, and occupational therapists. However, there are still important gaps in the knowledge and management of this syndrome.

Main body

The objective of this paper is to promote the interdisciplinary approach in the prevention and management of delirium as endorsed by a delirium society (European Delirium Association, EDA), a geriatrics society (European Geriatric Medicine Society, EuGMS), a nursing society (European Academy of Nursing Science, EANS), an occupational therapy society (Council of Occupational Therapists for European Countries, COTEC), and a physiotherapy society (International Association of Physical Therapists working with Older People of the World Confederation for Physical Therapy, IPTOP/WCPT).

Short conclusion

In this paper we have strongly promoted and supported interdisciplinary collaboration underlying the necessity of increasing communication among scientific societies. We have also provided suggestions on how to fill the current gaps via improvements in undergraduate and postgraduate delirium education among European Countries.

An Acute Care for Elders Quality Improvement Program for Complex, High-Cost Patients Yields Savings for the System

BACKGROUND

Acute Care for Elders (ACE) programs improve outcomes for older adults; however, little is known about whether impact varies with comorbidity severity.

OBJECTIVE

To describe differences in hospital-level outcomes between ACE and routine care across various levels of comorbidity burden.

DESIGN

Cross-sectional quality improvement study.

SETTING

A 716-bed teaching hospital.

PARTICIPANTS

Medical inpatients aged ≥70 years hospitalized between September 2014 and August 2017.

INTERVENTION

ACE care, including interprofessional rounds, geriatric syndromes screening, and care protocols, in an environment prepared for elders MEASUREMENTS: Total cost, length of stay (LOS), and 30-day readmissions. We calculated median differences for cost and LOS between ACE and usual care and explored variations across the distribution of outcomes at the 25th, 50th, 75th and 90th percentiles. Results were also stratified across quartiles of the combined comorbidity score.

RESULTS

A total of 1,429 ACE and 10,159 non-ACE patients were included in this study. The mean age was 81 years, 57% were female, and 81% were white. ACE patients had lower costs associated with care ranging from $171 at the 25th percentile to $3,687 at the 90th percentile, as well as lower LOS ranging from 0 days at the 25th percentile to 1.9 days at the 90th percentile. After stratifying by comorbidity score, the greatest differences in outcomes were among those with higher scores. There was no difference in 30-day readmission between the groups.

CONCLUSION

The greatest reductions in cost and LOS were in patients with greater comorbidity scores. Risk stratification may help hospitals prioritize admissions to ACE units to maximize the impact of the more intensive intervention.

State of the clinical science of perioperative brain health: report from the American Society of Anesthesiologists Brain Health Initiative Summit 2018

Cognitive recovery after anaesthesia and surgery is a concern for older adults, their families, and caregivers. Reports of patients who were 'never the same' prompted a scientific inquiry into the nature of what patients have experienced. In June 2018, the ASA Brain Health Initiative held a summit to discuss the state of the science on perioperative cognition, and to create an implementation plan for patients and providers leveraging the current evidence. This group included representatives from the AARP (formerly the American Association of Retired Persons), American College of Surgeons, American Heart Association, and Alzheimer's Association Perioperative Cognition and Delirium Professional Interest Area. This paper summarises the state of the relevant clinical science, including risk factors, identification and diagnosis, prognosis, disparities, outcomes, and treatment of perioperative neurocognitive disorders. Finally, we discuss gaps in current knowledge with suggestions for future directions and opportunities for clinical and translational projects.

Delirium: Medical Students' Knowledge and Effectiveness of Different Teaching Methods

OBJECTIVE

Medical schools are often blamed for inadequately training doctors on delirium. This study assesses the knowledge of medical students regarding delirium and evaluates different teaching methods for comparing learning outcomes.

METHODS

A video, a handout, and a video+handout were used as three different teaching methods. Students were randomly assigned to three groups and pre- and postintervention knowledge gains were compared. Interventions were held between 2015 and 2018 at the University of Heidelberg Medical School in Germany. Seventy-eight (video intervention 33; handout 26; video+handout 19) sixth-year medical students participated. Participants learned about delirium with the help of a video, a handout, and both a video+handout at the start of one-hour lectures dedicated to teaching about delirium. Pre- and postintervention questionnaires, comprising five multiple-choice questions and a self-estimated grade of knowledge about delirium, were used. Variables calculated were objective and subjective knowledge, recall, and accuracy of self-assessment. Microsoft Excel and analysis of covariance were used to analyze data.

RESULTS

Knowledge gains for all interventions were large (d>0.8) irrespective of gender. Post hoc comparison showed video and video+handout methods were more effective with high recall for video (92.8%). Students rated their knowledge as satisfactory, although they scored 11.4 out of 20. Preintervention knowledge level was correctly estimated by 31% of students, and postintervention by 40.3% students.

CONCLUSION

Teaching about delirium to medical students with a video resulted in better knowledge transfer and recall. Most medical students, particularly men, overestimated their knowledge about delirium.

The Bundled Hospital Elder Life Program-HELP and HELP in Home Care-and Its Association With Clinical Outcomes Among Older Adults Discharged to Home Healthcare

OBJECTIVES

To describe the Bundled Hospital Elder Life Program (HELP and HELP in Home Care), an adaptation of HELP, and examine the association of 30-day all-cause unplanned hospital readmission risk among older adults discharged to home care with and without Bundled HELP.

DESIGN

Matched case-control study.

SETTING

Two medical-surgical units within two midwestern rural hospitals and patient homes (home health).

PARTICIPANTS

Hospitalized patients, aged 65 years and older, discharged to home healthcare with and without Bundled HELP exposure between January 1, 2015, and September 30, 2017. Each case (Bundled HELP, n = 148) was matched to a control (non-Bundled HELP, n = 148) on Charlson Comorbidity Index, primary hospital diagnosis of orthopedic condition or injury, and cardiovascular disease using propensity score matching.

MEASUREMENTS

The primary study outcome was 30-day all-cause unplanned hospital readmission. Additional outcomes measured were 30-day emergency department (ED) visit, hospital length of stay (LOS), and total number of skilled home care visits.

RESULTS

Fewer cases (16.8%) than controls (28.4%) had a 30-day all-cause unplanned hospital readmission. The fully adjusted model showed significantly lower risk of 30-day hospital readmission for case (Bundled HELP) patients (0.41; 95% confidence interval = 0.22-0.77; P < .01). The difference between case (10.8%) and control (15.5%) 30-day ED visit was not significant (P = .23). A lower LOS for the case group was shown (P < .01), while the number of skilled home care visits was not significantly different between groups (P = .28).

CONCLUSION

HELP protocol implementation during a patient's hospital stay and as a continued component of home care among older adults at risk for cognitive and/or functional decline appears to be associated with favorable outcomes. Our initial evaluation supports continued study of the Bundled HELP. Further research is needed to confirm the initial findings and to evaluate the impact of the adapted model on functional outcomes and delirium incidence in the home.

Multimodal prehabilitation to reduce the incidence of delirium and other adverse events in elderly patients undergoing elective major abdominal surgery: An uncontrolled before-and-after study

Background

Delirium is a common and serious complication in elderly patients undergoing major abdominal surgery, with significant adverse outcomes. Successful strategies or therapies to reduce the incidence of delirium are scarce. The objective of this study was to assess the role of prehabilitation in reducing the incidence of delirium in elderly patients.

Methods

A single-center uncontrolled before-and-after study was conducted, including patients aged 70 years or older who underwent elective abdominal surgery for colorectal carcinoma or an abdominal aortic aneurysm between January 2013 and October 2015 (control group) and between November 2015 and June 2018 (prehabilitation group). The prehabilitation group received interventions to improve patients’ physical health, nutritional status, factors of frailty and preoperative anaemia prior to surgery. The primary outcome was incidence of delirium, diagnosed with the DSM-V criteria or the confusion assessment method. Secondary outcomes were additional complications, length of stay, unplanned ICU admission, length of ICU stay, readmission rate, institutionalization, and in-hospital or 30-day mortality.

Result

A total of 360 control patients and 267 prehabilitation patients were included in the final analysis. The mean number of prehabilitation days was 39 days. The prehabilitation group had a higher burden of comorbidities and was more physically and visually impaired at baseline. At adjusted logistic regression analysis, delirium incidence was reduced significantly from 11.7 to 8.2% (OR 0.56; 95% CI 0.32–0.98; P = 0.043). No statistically significant effects were seen on secondary outcomes.

Conclusion

Current prehabilitation program is feasible and safe, and can reduce delirium incidence in elderly patients undergoing elective major abdominal surgery. This program merits further evaluation.

Structural Brain Changes in Delirium: An Integrative Review

Delirium is a serious complication of acute illness. Little is known, however, regarding the neurobiology of delirium, largely due to challenges in studying the complex inpatient population. Neuroimaging is one noninvasive method that can be used to study structural and functional brain abnormalities associated with delirium. The purpose of this integrative literature review was to examine the content and quality of current structural neuroimaging evidence in delirium. After meeting inclusion criteria, 11 articles were included in the review. Commonly noted structural abnormalities were impaired white matter integrity, brain atrophy, ischemic lesions, edema, and inflammation. Findings demonstrated widespread alterations in several brain structures. Limitations of the studies in this review included small sample sizes, inappropriate or questionable delirium measurements, and failure to consider confounding variables. This review provides insight into possible structural changes responsible for the signs and symptoms seen in patients with delirium, but more high-quality studies are needed.

Recent Advances in Preventing and Managing Postoperative Delirium

Postoperative delirium is a common and harrowing complication in older surgical patients. Those with cognitive impairment or dementia are at especially high risk for developing postoperative delirium; ominously, it is hypothesized that delirium can accelerate cognitive decline and the onset of dementia, or worsen the severity of dementia. Awareness of delirium has grown in recent years as various medical societies have launched initiatives to prevent postoperative delirium and alleviate its impact. Unfortunately, delirium pathophysiology is not well understood and this likely contributes to the current state of low-quality evidence that informs perioperative guidelines. Along these lines, recent prevention trials involving ketamine and dexmedetomidine have demonstrated inconsistent findings. Non-pharmacologic multicomponent initiatives, such as the Hospital Elder Life Program, have consistently reduced delirium incidence and burden across various hospital settings. However, a substantial portion of delirium occurrences are still not prevented, and effective prevention and management strategies are needed to complement such multicomponent non-pharmacologic therapies. In this narrative review, we examine the current understanding of delirium neurobiology and summarize the present state of prevention and management efforts.

Prehabilitation is better than cure

PURPOSE OF REVIEW

With a continuously growing number of older patients undergoing major surgical procedures, reliable parameters practicable in perioperative routine revealing those patients at risk are urgently needed. Recently, the concept of 'prehabilitation' with its key elements exercise, nutrition and psychological stress reduction especially in frail patients is attracting increasing attention.

RECENT FINDINGS

Literature search revealed a huge amount of publications in particular within the last 12 months. Although a single definition of both frailty and prehabilitation is still to be made, various players in the perioperative setting obviously are becoming increasingly convinced about a possible benefit of the program - referring to different components and measures performed. Although physiologically advantages seem obvious, there is hardly any reliable data on clinical outcomes resulting from properly performed studies. This applies especially to octogenarians; thus those at risk for adverse events the concept originally addresses.

SUMMARY

Identifying high-risk patients at the earliest possible stage and increasing their physiological reserve prior to surgery is a promising approach that seems to result in remarkable improvements for older patients. However, further studies on effectiveness in a highly heterogeneous population and agreement on a common concept are mandatory before a final judgement can be given.

Frailty Identification and Care Pathway: An Interdisciplinary Approach to Care for Older Trauma Patients

BACKGROUND

Frailty is a well-established marker of poor outcomes in geriatric trauma patients. There are few interventions to improve outcomes in this growing population. Our goal was to determine if an interdisciplinary care pathway for frail trauma patients improved in-hospital mortality, complications, and 30-day readmissions.

STUDY DESIGN

This was a retrospective cohort study of frail patients ≥65 years old, admitted to the trauma service at an academic, urban level I trauma center between 2015 and 2017. Patients transferred to other services and those who died within the first 24 hours were excluded. An interdisciplinary protocol for frail trauma patients, including early ambulation, bowel/pain regimens, nonpharmacologic delirium prevention, nutrition/physical therapy consults, and geriatrics assessments, was implemented in 2016. Our main outcomes were delirium, complications, in-hospital mortality, and 30-day readmission, which were compared with these outcomes in patients treated the year before the pathway was implemented. Multivariate logistic regression was used to determine the association of being on the pathway with outcomes.

RESULTS

There were 125 and 144 frail patients in the pre- and post-intervention cohorts, respectively. There were no significant demographic differences between the 2 groups. Among both groups, the mean age was 83.51 years (SD 7.11 years), 60.59% were female, and median Injury Severity Score was 10 (interquartile range 9 to 14). In univariate analysis, there were no significant differences in complications (28.0% vs 28.5%, respectively, p = 0.93); however, there was a significant decrease in delirium (21.6% to 12.5%, respectively, p = 0.04) and 30-day readmission (9.6% to 2.7%, respectively, p = 0.01). After adjusting for patient characteristics, patients on the pathway had lower delirium (odds ratio [OR] 0.44, 95% CI 0.22 to 0.88, p = 0.02) and 30-day readmission rates (OR 0.25, 95% CI 0.07 to 0.84, p = 0.02), than pre-pathway patients.

CONCLUSIONS

An interdisciplinary care protocol for frail geriatric trauma patients significantly decreases their delirium and 30-day readmission risk. Implementing pathways standardizing care for these vulnerable patients could improve their outcomes after trauma.

The Overlap Between Falls and Delirium in Hospitalized Older Adults: A Systematic Review

Falls frequently occur in persons with cognitive impairment, including delirium. This article presents a systematic review of the association between falls and delirium in adults aged 65 years or older. For the studies that compared falls and delirium, the risk ratio was consistently elevated (median RR 4.5, range 1.4-12.6) and statistically significant in all but one study. These results suggest that falls and delirium are inextricably linked. There is a need to further refine fall risk assessment tools and protocols to specifically include delirium for consideration as a risk factor that needs additional assessment and management.

Sleep and Delirium in Pediatric Critical Illness: What Is the Relationship?

With growing recognition of pediatric delirium in pediatric critical illness there has also been increased investigation into improving recognition and determining potential risk factors. Disturbed sleep has been assumed to be one of the key risk factors leading to delirium and is commonplace in the pediatric critical care setting as the nature of intensive care requires frequent and invasive monitoring and interventions. However, this relationship between sleep and delirium in pediatric critical illness has not been definitively established and may, instead, reflect significant overlap in risk factors and consequences of underlying neurologic dysfunction. We aim to review the existing tools for evaluation of sleep and delirium in the pediatric critical care setting and review findings from recent investigations with application of these measures in the pediatric intensive care unit.
