Preventing delirium in an acute hospital using a non-pharmacological intervention

Understanding family carer experiences and perceptions of engagement in delirium prevention and care for adults in hospital: Qualitative systematic review

AIM

To identify, describe and synthesise what is known about family carers' experiences and perspectives of engagement in delirium prevention and care for adults in hospital.

DESIGN

Systematic review and synthesis of qualitative evidence.

DATA SOURCES

Comprehensive literature search within PubMed, CINAHL, EMBASE, Scopus, Cochrane Central and PsycInfo databases to August 2022. Peer reviewed original qualitative research published in English.

METHODS

Data were extracted using Covidence systematic review software. Methodological quality was reviewed against the Critical Appraisal Skills Program (CASP) Qualitative Checklist. Thematic synthesis was used to develop analytical themes. Confidence in the Evidence from Reviews of Qualitative Research (GRADE-CERQual) framework was applied to findings.

RESULTS

Of 3429 records identified, 29 met criteria for final inclusion. Studies included a range of settings (intensive care, medical and surgical wards) and family carer types (spouse, daughter, parent and friend). Three primary themes Shared Caregiving, Partnership and Support, Communication for Shared Understanding and three cross-cutting contextual themes Care Transitions, Family Carer Context and Hospital Context were identified. Family carers have mixed experiences of involvement in delirium care and prevention. Family carer engagement in care impacted perceptions of care quality and their own self-efficacy. Where person-centred care expectations were not met, some family carers adopted compensatory or care contingency strategies. Information sharing and timely support from hospital staff who understood the carer context supported carer involvement. Supportive physical environments and addressing power imbalances allowed greater engagement.

CONCLUSION

Family carers often wish to be involved in delirium prevention and care, but need to be recognised as individuals, listened to, informed and supported to optimise their contribution.

IMPACT

The review findings can guide health professional and decision makers to optimise family carer involvement in delirium care programs.

Delirium Prevention in Early Rehabilitation During Acute Hospitalization and Implementation of Programs Specifically Tailored to Older Patients with Cognitive Impairment: A Scoping Review with Meta-Analysis

BACKGROUND

No systematic review on delirium prevention within early, hospital-based rehabilitation on implementation of approaches specifically tailored for patients with cognitive impairment (PwCI), such as Alzheimer's disease or vascular dementia, has been published despite the high relevance of specific medical care in this vulnerable population.

OBJECTIVE

To document design and effectiveness of delirium prevention programs by early rehabilitation during acute, hospital-based medical care and implementation of programs specifically tailored to PwCI.

METHODS

In a three-step approach, we first identified published systematic reviews of hospital-based, early rehabilitation interventions for older persons (>65 years) in relevant databases. In a second step, we screened each single trial of included reviews according to predefined inclusion criteria. In a third step, we analyzed studies with focus on delirium prevention.

RESULTS

Among n = 25 studies identified, almost all intervention programs did not specifically target cognitive impairment (CI). Interventions were heterogeneous (modules: n = 2-19); almost all study samples were mixed/unspecified for cognitive status with more affected patients excluded. Only one study exclusively included delirium patients, and only one included CI patients. Results of random effect meta-analysis showed significant effects of generic programs to reduce delirium incidence during hospitalization by 41% (p < 0.001, odds ratio, 95% confidence interval: 0.59 [0.49, 0.71] with modest heterogeneity (I2: 30%).

CONCLUSIONS

Study results document a lack of implementation for delirium prevention programs specifically tailored to PwCI by early, hospital-based rehabilitation. Specifying existing rehab concepts or augmenting them by CI-specific modules may help to develop, optimize, and implement innovative delirium prevention in PwCI in acute medical care.

Partnering with carers in the management of delirium in general acute care settings: An integrative review

OBJECTIVES

Delirium is a common, preventable condition. However, delirium is poorly recognised and often missed because symptoms are misinterpreted, and risk factors overlooked by health-care professionals. Carers usually have intimate knowledge about the person they care for. Therefore, they are well placed within care teams to implement delirium prevention strategies, identify symptoms and support the early diagnosis of delirium. The aim of this integrative review was to synthesise findings from the published research reporting on partnering with carers in the management of delirium in general acute care settings.

METHODS

Five databases (Medline-EBSCO, PubMed, PsycINFO, ProQuest, CINAHL and SCOPUS) were searched to identify primary research regarding partnering with carers in the management of delirium in acute care settings, and results were synthesised. PRISMA guidelines were adhered to, and quality appraisal was conducted using the Mixed Methods Appraisal Tool.

RESULTS

All seven studies reported that partnering with carers was a viable strategy in the management of delirium to maximise outcomes for people at risk of or experiencing delirium and that increasing carers' knowledge of delirium was key. The synthesis of findings also identified two themes: Increasing knowledge and Effective partnerships.

CONCLUSIONS

A collaborative approach to increasing carers' and nurses' knowledge about the management of delirium, coupled with education on how to develop therapeutic nurse-carer relationships, is important for ongoing effective partnerships in the management of delirium. Good communication supported effective partnerships, which enabled both nurses and carers the opportunity to express their needs and concerns and negotiate collaborative involvement in the management of delirium.

Family-centered delirium prevention and treatment using video calls: the FACE Delirium trial

PURPOSE

In the FACE Delirium trial, we investigated the feasibility of a structured FAmily-CEntered delirium prevention and treatment during the corona pandemic.

METHODS

Patients hospitalized in a German geriatric medicine department were included in this single-center, prospective, single-arm feasibility study. Their relatives received a short training on delirium and volunteers or paid staff members facilitated video calls. The primary endpoint was reached when contact between patients and their relatives occurred on ≥ 80% of treatment days, either via video call or visit.

RESULTS

38 patients were included (age 83.0 ± 5.9 years; 73.7% women). 76.3% reached the primary endpoint. Due to the pandemic, 99.3% of the contacts were video calls with a duration of 24.8 ± 16.3 min.

CONCLUSION

Family-centered delirium prevention and treatment using video calls is feasible among hospitalized geriatric patients. Daily implementation in clinical practice poses challenges and requires motivated and qualified staff.

Perioperative Factors Associated With Postoperative Delirium in Patients Undergoing Noncardiac Surgery: An Individual Patient Data Meta-Analysis

Importance

Postoperative delirium (POD) is a common and serious complication after surgery. Various predisposing factors are associated with POD, but their magnitude and importance using an individual patient data (IPD) meta-analysis have not been assessed.

Objective

To identify perioperative factors associated with POD and assess their relative prognostic value among adults undergoing noncardiac surgery.

Data Sources

MEDLINE, EMBASE, and CINAHL from inception to May 2020.

Study Selection

Studies were included that (1) enrolled adult patients undergoing noncardiac surgery, (2) assessed perioperative risk factors for POD, and (3) measured the incidence of delirium (measured using a validated approach). Data were analyzed in 2020.

Data Extraction and Synthesis

Individual patient data were pooled from 21 studies and 1-stage meta-analysis was performed using multilevel mixed-effects logistic regression after a multivariable imputation via chained equations model to impute missing data.

Main Outcomes and Measures

The end point of interest was POD diagnosed up to 10 days after a procedure. A wide range of perioperative risk factors was considered as potentially associated with POD.

Results

A total of 192 studies met the eligibility criteria, and IPD were acquired from 21 studies that enrolled 8382 patients. Almost 1 in 5 patients developed POD (18%), and an increased risk of POD was associated with American Society of Anesthesiologists (ASA) status 4 (odds ratio [OR], 2.43; 95% CI, 1.42-4.14), older age (OR for 65-85 years, 2.67; 95% CI, 2.16-3.29; OR for >85 years, 6.24; 95% CI, 4.65-8.37), low body mass index (OR for body mass index <18.5, 2.25; 95% CI, 1.64-3.09), history of delirium (OR, 3.9; 95% CI, 2.69-5.66), preoperative cognitive impairment (OR, 3.99; 95% CI, 2.94-5.43), and preoperative C-reactive protein levels (OR for 5-10 mg/dL, 2.35; 95% CI, 1.59-3.50; OR for >10 mg/dL, 3.56; 95% CI, 2.46-5.17). Completing a college degree or higher was associated with a decreased likelihood of developing POD (OR 0.45; 95% CI, 0.28-0.72).

Conclusions and Relevance

In this systematic review and meta-analysis of individual patient data, several important factors associated with POD were found that may help identify patients at high risk and may have utility in clinical practice to inform patients and caregivers about the expected risk of developing delirium after surgery. Future studies should explore strategies to reduce delirium after surgery.

Educational intervention for family caregivers of older adults with delirium: An integrative review

AIM

To propose educational strategies to prevent delirium in older adults.

DESIGN

Integrative review.

METHODS

This review followed the methodology of Whittemore and Knafl (J Adv Nurs 52(5):546-553, 2005. 10.1111/j.1365-2648.2005.03621.x).

DATA SOURCES

A literature search was performed of the PubMed, CINAHL, Embase, Cochrane Library CENTRAL, and Scopus databases on 8 July 2022.

RESULTS

Three themes of educational interventions were identified: capacity building, resource provision and enhancement of relationships, collectively termed Fa-CARE. Educational interventions improved family caregivers' knowledge about delirium, their anxiety; depression; self-efficacy; and attitudes. Among older adults, these interventions improved the duration, severity and incidence of delirium; functional abilities; and length of hospital stay.

CONCLUSION

Providing education to family caregivers benefits both those caregivers and the older adults. When planning educational intervention, diverse and innovative approaches need to be considered.

IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE

This study can guide family education regarding the care of older adults with delirium.

IMPACT

Educational interventions positively impacted both family caregivers and older adults with delirium. Educational interventions provide family caregivers with resources, improve their capacity for delirium management, and enhance their relationships with older adults. This study suggests future directions in education for family caregivers of older adults with delirium.

REPORTING METHOD

This review adhered to the EQUATOR guidelines by using the PRISMA 2020 checklist.

Transcutaneous electrical acupoint stimulation combined with an integrated perioperative nursing program prevents subsyndromal delirium in older patients after joint replacement

OBJECTIVES

This study aimed to develop transcutaneous electrical acupoint stimulation combined with an integrated perioperative nursing program and evaluate its effects on preventing subsyndromal delirium (SSD) and postoperative delirium (POD) in older patients after joint replacement surgery.

METHODS

Participants were randomly divided into two groups, the experimental group (n = 48) was given transcutaneous electrical acupoint stimulation combined with an integrated perioperative nursing program based on the routine care of the control group (n = 49). The incidence of SSD and POD in a week after surgery was recorded. Assessments of delirium severity, cognition, anxiety, and depression were also conducted at baseline and on postoperative day 7.

RESULTS

The findings indicate that the intervention program had significant advances in alleviating the severity of delirium, cognitive impairment, anxiety, and depression but failed to reduce the incidence of SSD and POD.

CONCLUSIONS

Our study indicated that TEAS combined with an integrated perioperative nursing program has a beneficial effect on alleviating symptoms of delirium, cognitive dysfunction, anxiety, and depression in older adults after joint replacement surgery.

Prognostic significance of frailty in older patients with hip fracture: a systematic review and meta-analysis

PURPOSE

Hip fracture (HF) has become a major healthcare concern associated with higher mortality in older patients. Frailty is one of the most important problems in aging population but its prognostic value in HF remains susceptible. This systematic review and meta-analysis aimed to evaluate the association between frailty and adverse outcomes in older patients with HF.

METHODS

We systematically searched electrical databases including PubMed and Embase to find eligible literature with end-search restriction of February 20, 2021. The main endpoints were all-cause mortality, peri-operative complications, abnormal discharge, and length of stay (LOS). Pooled effect size was calculated by random-effects or fixed-effect model according to study heterogeneity. Three subgroup analyses based on follow-up times, study design, and frailty criteria were conducted.

RESULTS

We screened 22 studies out of 1599 identified studies in our analysis. Compared with normal patients, frail ones had a higher risk of mortality both before (OR = 3.48, 95% CI: 2.50-4.85, I² = 87.2%, P < 0.001) and after (OR = 1.87, 95% CI: 1.44-2.44, I² = 85.5%, P < 0.001) adjustment. The incidence of peri-operative complications, abnormal discharge, and prolonged LOS also significantly increased in frail subjects. There was no publication bias observed and the pooled results were stable based on sensitivity analysis.

CONCLUSION

Overall, more attention needs to be paid to the prognostic effects caused by frailty in seniors with HF. Better understanding of the association between frailty and adverse outcomes in HF could help doctors perform co-management across orthopaedic and geriatric departments.

Impact of Family Presence on Delirium in Critically Ill Patients: A Retrospective Cohort Study

OBJECTIVE

To assess the effect of family presence on the prevalence and duration of delirium in adults admitted to an ICU.

DESIGN

Retrospective cohort study.

SETTING

Medical-surgical ICUs in Alberta, AB, Canada.

PATIENTS

A population of 25,537 unique patients admitted at least once to an Alberta ICU.

METHODS

We obtained electronic health records of consecutive adults (≥ 18 yr) admitted to one of 14 medical-surgical ICU in Alberta, Canada, from January 1, 2014, to December 30, 2018. Family presence was quantified using a validated algorithm and categorized as: 1) physical presence in ICU, 2) telephone call only, and 3) no presence (reference group). Delirium was measured using the Intensive Care Delirium Screening Checklist (ICDSC) and defined as an ICDSC greater than or equal to 4. Multivariable mixed-effects logistic and linear regression were used to evaluate the association between family presence and prevalence (binary) and duration (d) of delirium, respectively.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

The association between family presence and delirium prevalence differed according to admission type and admission Glasgow Coma Scale (GCS). Among medical and emergency surgical patients irrespective of admission GCS, physical presence of family was not significantly associated with the prevalence of delirium. In elective surgical patients, physical presence of family was associated with decreased prevalence of delirium in patients with intact Glasgow Coma Scale (GCS = 15; adjusted odds ratio, 0.60; 95% CI, 0.39-0.97; p = 0.02). Physical presence of family (adjusted mean difference [AMD] -1.87 d; 95% CI, -2.01 to -1.81; p < 0.001) and telephone calls (AMD -1.41 d; 95% CI, -1.52 to -1.31; p < 0.001) were associated with decreased duration of delirium in all patients.

CONCLUSIONS

The effects of family presence on delirium are complex and dependent on type of visitation, reason for ICU admission, and brain function on ICU admission.

Stakeholder perspectives of a pilot multicomponent delirium prevention intervention for adult patients with advanced cancer in palliative care units: A behaviour change theory-based qualitative study

BACKGROUND

Theory-based and qualitative evaluations in pilot trials of complex clinical interventions help to understand quantitative results, as well as inform the feasibility and design of subsequent effectiveness and implementation trials.

AIM

To explore patient, family, clinician and volunteer ('stakeholder') perspectives of the feasibility and acceptability of a multicomponent non-pharmacological delirium prevention intervention for adult patients with advanced cancer in four Australian palliative care units that participated in a phase II trial, the 'PRESERVE pilot study'.

DESIGN

A trial-embedded qualitative study via semi-structured interviews and directed content analysis using Michie's Behaviour Change Wheel and the Theoretical Domains Framework.

SETTING/PARTICIPANTS

Thirty-nine people involved in the trial: nurses (n = 17), physicians (n = 6), patients (n = 6), family caregivers (n = 4), physiotherapists (n = 3), a social worker, a pastoral care worker and a volunteer.

RESULTS

Participants' perspectives aligned with the 'capability', 'opportunity' and 'motivation' domains of the applied frameworks. Of seven themes, three were around the alignment of the delirium prevention intervention with palliative care (intervention was considered routine care; intervention aligned with the compassionate and collaborative culture of palliative care; and differing views of palliative care priorities influenced perspectives of the intervention) and four were about study processes more directly related to adherence to the intervention (shared knowledge increased engagement with the intervention; impact of the intervention checklist on attention, delivery and documentation of the delirium prevention strategies; clinical roles and responsibilities; and addressing environmental barriers to delirium prevention).

CONCLUSION

This theory-informed qualitative study identified multiple influences on the delivery and documentation of a pilot multicomponent non-pharmacological delirium prevention intervention in four palliative care units. Findings inform future definitive studies of delirium prevention in palliative care.Australian New Zealand Clinical Trials Registry, ACTRN12617001070325; https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=373168.

Moral distress amongst palliative care doctors working during the COVID-19 pandemic: A narrative-focussed interview study

BACKGROUND

Palliative care professionals have had to adapt to rapidly changing COVID-19 restrictions with personal protective equipment and physical distancing measures impacting face-to-face communication with patients and relatives.

AIM

To explore the narratives of palliative care doctors working during the pandemic to understand their experiences at a personal and professional level.

DESIGN

In-depth narrative interviews were carried out via video call. Interviews were transcribed verbatim and analysed using a joint paradigmatic and narrative approach to elucidate common themes and closely explore individual narratives.

SETTING/PARTICIPANTS

Eight palliative care doctors who had worked on a hospice inpatient unit in the UK before and during the pandemic were recruited from two hospices in Scotland.

RESULTS

Three intersecting themes are described, the most significant being moral distress. Participants articulated a struggle to reconcile their moral convictions with the restrictions enforced, for example, wanting to provide support to patients through physical proximity but being unable to. To differing degrees, this resulted in internal conflict and emotional distress. Two further themes arose: the first concerned a loss of humanity in interaction and a striving to re-humanise communication through alternative means; the second being a change in staff morale as the pandemic progressed.

CONCLUSIONS

Restrictions had a considerable impact on palliative care doctors' ability to communicate with and comfort patients which led to moral distress and contributed to decreasing morale. Future research could explore moral distress in palliative care settings internationally during the pandemic with a view to compare the factors affecting how moral distress was experienced.

[Delirium prevention and management: Development and implementation of a non-pharmacological catalog of measures in the acute setting]

Delirium prevention and management: Development and implementation of a non-pharmacological catalog of measures in the acute setting Abstract. Background: In October 2018, a new delirium management concept was developed in a university hospital for cardiovascular diseases. As part of a multi-professional approach, the previously established "Evidence-based Nursing working group (AK EBN)", consisting of academically qualified nurses from the hospital, was involved in the implementation process. Aim: The AK EBN aimed to identify effective non-pharmacological interventions to prevent and treat delirium and to establish how these interventions could influence delirium rates in hospital patients. Methods: The EbN method was employed to address the study question applying the PICO framework (Behrens & Langer, 2016) as the bases for systematic searches in different databases. Relevant studies were identified, data were extracted, displayed in tables and discussed within the AK using established critical appraisal tools for quality assessment. Results: Despite a heterogeneous study sample, results showed that there is meaningful evidence for the effectiveness of intervention bundles on the reduction of delirium rates. Bundles include for example, aspects of orientation and noise reduction. As a result, a catalogue of non-pharmacological interventions, communication aids, and a guide for involving caregivers in the prevention and treatment of delirium were developed. Additionally, continuing training events held by the participants of AK EBN were organized. Conclusions: To promote the successful implementation of projects in practice, the involvement of all stakeholders is important. As part of a skill-grade-mix, nurses made an important contribution in this multi-professional project.

Review of Postoperative Delirium in Geriatric Patients After Hip Fracture Treatment

Introduction

Postoperative delirium (POD) is a serious complication occurring in 4–53.3% of geriatric patients undergoing surgeries for hip fracture. Incidence of hip fractures is projected to grow 11.9% from 258,000 in 2010 to 289,000 in 2030 based on 1990 to 2010 data. As prevalence of hip fractures is projected to increase, POD is also anticipated to increase.

Signficance

Postoperative delirium remains the most common complication of emergency hip fracture surgery leading to high morbidity and mortality rates despite significant research conducted regarding this topic. This study reviews literature from 1990 to 2021 regarding POD in geriatric hip fracture management.

Results

Potentially modifiable and non-modifiable risk factors for developing POD include, but are not limited to, male gender, older age, multiple comorbidities, specific comorbidities (dementia, cognitive impairment, diabetes, vision impairment, and abnormal blood pressure), low BMI, preoperative malnutrition, low albumin, low hematocrit, blunted preoperative cytokines, emergency surgery, time to admission and surgery, preoperative medical treatment, polypharmacy, delirium-inducing medications, fever, anesthesia time, and sedation depth and type. Although the pathophysiology remains unclear, the leading theories suggest neurotransmitter imbalance, inflammation, and electrolyte or metabolic derangements as the underlying cause of POD. POD is associated with increased length of hospital stay, cost, morbidity, and mortality. Prevention and early recognition are key factors in managing POD. Methods to reduce POD include utilizing interdisciplinary teams, educational programs for healthcare professionals, reducing narcotic use, avoiding delirium-inducing medications, and multimodal pain control.

Conclusion

While POD is a known complication after hip fracture surgery, further exploration in prevention is needed. Early identification of risk factors is imperative to prevent POD in geriatric patients. Early prevention will enhance delivery of health care both pre- and post-operatively leading to the best possible surgical outcome and better quality of life after hip fracture treatment.

Does delirium prevention reduce risk of in-patient falls among older adults? A systematic review and trial sequential meta-analysis

OBJECTIVES

To determine whether delirium prevention interventions reduce the risk of falls among older hospitalised patients.

METHODS

A systematic search of health-care databases was undertaken. Given the frequency of small sample sized trials, a trial sequential meta-analysis was conducted to present estimate summary effects to date. A Bayesian approach was used to estimate the posterior probability of the delirium prevention interventions reducing falls risk by various clinically relevant levels.

RESULTS

Five randomised controlled trials were included in our final meta-analysis. There was a 43% reduction in the risk of falls among participants in the delirium prevention intervention arm, compared to the control; however, confidence intervals were wide (RE RR = 0.57, 95% CI 0.32; 1.00, p = 0.05). This result was found to be statistically significant, according to traditional significance levels (z > 1.96) and the more conservative trial sequential analysis monitoring boundaries. The posterior probabilities of the delirium prevention intervention reducing the risk of falls by 10%, 20% and 30% were 0.86, 0.63 and 0.29 respectively.

CONCLUSIONS

The results of this systematic review and trial sequential meta-analysis suggest that delirium prevention trials may reduce the risk of in-hospital falls among older patients by 43%. However, despite significant risk reduction found upon meta-analysis, the variation among study populations and intervention components raised questions around its application in clinical practice. Further research is required to investigate what the necessary components of a multifactorial intervention are to reduce both delirium and fall incidence among older adult in-patients.

Geriatric Preoperative Optimization: A Review

This review summarizes best practices for the perioperative care of older adults as recommended by the American Geriatrics Society, American Society of Anesthesiologists, and American College of Surgeons, with practical implementation strategies that can be readily implemented in busy preoperative or primary care clinics. In addition to traditional cardiopulmonary screening, older patients should undergo a comprehensive geriatric assessment. Rapid screening tools such as the Mini-Cog, Patient Health Questionnaire-2, and Frail Non-Disabled Survey and Clinical Frailty Scale, can be performed by multiple provider types and allow for quick, accurate assessments of cognition, functional status, and frailty screening. To assess polypharmacy, online resources can help providers identify and safely taper high-risk medications. Based on preoperative assessment findings, providers can recommend targeted prehabilitation, rehabilitation, medication management, care coordination, and/or delirium prevention interventions to improve postoperative outcomes for older surgical patients. Structured goals of care discussions utilizing the question-prompt list ensures that older patients have a realistic understanding of their surgery, risks, and recovery. This preoperative workup, combined with engaging with family members and interdisciplinary teams, can improve postoperative outcomes.

PAINT I: the effect of art therapy in preventing and managing delirium among hospitalized older adults in the PAINT I study-a proof-of-concept trial

BACKGROUND

Delirium is common among older hospitalized patients and is regarded as a negative outcome parameter. Non-pharmacological strategies have been shown to be effective in the prevention and management of delirium. This study aimed to determine the effectiveness of art therapy as part of a multicomponent intervention in preventing and managing delirium in hospitalized older patients.

METHODS

138 patients at risk of developing delirium were included and received art therapy twice daily for 25 min using a mobile atelier. 107 participants were included in the final analysis (N = 53 intervention, N = 54 control). The primary outcome was the effectiveness of art therapy in preventing delirium. The secondary outcome was to determine its impact on duration of delirium in patients with existing delirium. Delirium was assessed using the Nursing delirium Screening Scale (Nu-DESC).

RESULTS

8 patients (7.5%) developed new onset delirium after admission, equally distributed among control and intervention group. Therefore, no valid statistical analysis could be performed. There was a statistically non-significant decrease in the duration of delirium in the intervention group (4 days, IQR 2.25-8.75) compared to the control group (7 days, IQR 5-10), Mann-Whitney-U-Test p-value = 0.26. After stratifying by dementia diagnosis on admission, the non-significant decrease in duration of delirium in the intervention group was more apparent in patients without dementia.

CONCLUSION

Findings from this study showed that the integration of art therapy as part of a multicomponent intervention in delirium management is feasible, and can reduce duration of delirium among hospitalized older adults.

A framework of social determinants of health for delirium tailored to older adults

Delirium is a debilitating medical condition that disproportionately affects hospitalized older adults and is associated with adverse health outcomes, increased mortality, and high medical costs. Efforts to understand delirium risk in hospitalized older adults have focused on examining medical comorbidities, pre-existing cognitive deficits, and other clinical and demographic factors present in the period proximate to the hospitalization. The contribution of social determinants of health (SDOH), including social circumstances, environmental characteristics, and early-life exposures, referred as the social exposome, to delirium risk is poorly understood. Increased knowledge about the influence of SDOH will offer a more comprehensive understanding of factors that may increase vulnerability to delirium and poor outcomes. Clinically, these efforts can guide the development and implementation of holistic preventive strategies to improve clinical outcomes. We propose a SDOH framework for delirium adapted for older adults. We provide the definition, description, and rationale for the domains and variables in our proposed model.

Critical Care Nurses' Experiences Caring for Patients When Relatives Were not Allowed in the ICUs due to COVID-19 Pandemic

Introduction

Health care workers faced new challenges during the COVID-19 pandemic when physical contact with relatives more or less disappeared.

Objectives

The aim of this study is to describe the experiences of critical care nurses (CCNs) working in intensive care units (ICUs) under the visiting restrictions imposed as a result of COVID-19.

Method

This study followed a qualitative design. The purposive sample included CCNs with at least 1 year of experience working in an ICU with a visiting policy affected by the pandemic. Data collection was carried out via semi-structured interviews and analyzed through a qualitative content analysis with an inductive approach.

Results

The study results are presented in three categories with 10 subcategories. CCNs value the presence of patients’ relatives at the bedside and described many challenges when relatives could not be present with the patient during the pandemic.

Conclusion

Close relatives are able to share essential information about the patients and provide much-needed emotional support to them, the relatives’ role is of central importance and CCNs value their presence in ICUs more than any positive consequences of them not being there.

The family in preventing delirium in the intensive care unit: Scoping review

INTRODUCTION

Delirium is cognitive impairment related to negative inpatient outcomes in the Intensive Care Unit (ICU), family interventions have been shown to be effective in reducing the incidence of this condition.

OBJECTIVE

To identify strategies that include the family in the prevention of delirium in the adult intensive care unit that can be integrated into ABCDEF.

INCLUSION CRITERIA

Studies describing actions and interventions involving caregivers and family members in the ICU for the prevention of delirium, conducted in the last five years, available in full text, in English and Spanish, Portuguese and in adults.

METHODS

A scope review was conducted using the keywords "Critical Care, Delirium, Family, Primary Prevention" in 11 databases (PubMed, Virtual Health Library, Cochrane Library, TRIP Data base, EBSCO, Ovid Nursing, Springer, Scopus, Dialnet, Scielo, Lilacs) and other sources (Open Gray, Google Scholar), between August - October 2019; 8 studies were considered relevant and were analysed.

RESULTS

The results were described in 3 categories: flexibility vs. restriction of visits in the ICU, Reorientation as a prevention strategy and post-ICU syndrome in the family.

CONCLUSION

Extended visits, development of family-mediated activities, and redirection are non-pharmacological strategies that reduce the incidence of delirium in the ICU and offer multiple benefits to the patient and family/caregiver.

Non-pharmacological interventions for preventing delirium in hospitalised non-ICU patients

BACKGROUND

Delirium is an acute neuropsychological disorder that is common in hospitalised patients. It can be distressing to patients and carers and it is associated with serious adverse outcomes. Treatment options for established delirium are limited and so prevention of delirium is desirable. Non-pharmacological interventions are thought to be important in delirium prevention.  OBJECTIVES: To assess the effectiveness of non-pharmacological interventions designed to prevent delirium in hospitalised patients outside intensive care units (ICU).

SEARCH METHODS

We searched ALOIS, the specialised register of the Cochrane Dementia and Cognitive Improvement Group, with additional searches conducted in MEDLINE, Embase, PsycINFO, CINAHL, LILACS, Web of Science Core Collection, ClinicalTrials.gov and the World Health Organization Portal/ICTRP to 16 September 2020. There were no language or date restrictions applied to the electronic searches, and no methodological filters were used to restrict the search.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) of single and multicomponent non-pharmacological interventions for preventing delirium in hospitalised adults cared for outside intensive care or high dependency settings. We only included non-pharmacological interventions which were designed and implemented to prevent delirium.  DATA COLLECTION AND ANALYSIS: Two review authors independently examined titles and abstracts identified by the search for eligibility and extracted data from full-text articles. Any disagreements on eligibility and inclusion were resolved by consensus. We used standard Cochrane methodological procedures. The primary outcomes were: incidence of delirium; inpatient and later mortality; and new diagnosis of dementia. We included secondary and adverse outcomes as pre-specified in the review protocol. We used risk ratios (RRs) as measures of treatment effect for dichotomous outcomes and between-group mean differences for continuous outcomes. The certainty of the evidence was assessed using GRADE. A complementary exploratory analysis was undertaker using a Bayesian component network meta-analysis fixed-effect model to evaluate the comparative effectiveness of the individual components of multicomponent interventions and describe which components were most strongly associated with reducing the incidence of delirium.

MAIN RESULTS

We included 22 RCTs that recruited a total of 5718 adult participants. Fourteen trials compared a multicomponent delirium prevention intervention with usual care. Two trials compared liberal and restrictive blood transfusion thresholds. The remaining six trials each investigated a different non-pharmacological intervention. Incidence of delirium was reported in all studies.  Using the Cochrane risk of bias tool, we identified risks of bias in all included trials. All were at high risk of performance bias as participants and personnel were not blinded to the interventions. Nine trials were at high risk of detection bias due to lack of blinding of outcome assessors and three more were at unclear risk in this domain.  Pooled data showed that multi-component non-pharmacological interventions probably reduce the incidence of delirium compared to usual care (10.5% incidence in the intervention group, compared to 18.4% in the control group, risk ratio (RR) 0.57, 95% confidence interval (CI) 0.46 to 0.71, I² = 39%; 14 studies; 3693 participants; moderate-certainty evidence, downgraded due to risk of bias).  There may be little or no effect of multicomponent interventions on inpatient mortality compared to usual care (5.2% in the intervention group, compared to 4.5% in the control group, RR 1.17, 95% CI 0.79 to 1.74, I² = 15%; 10 studies; 2640 participants; low-certainty evidence downgraded due to inconsistency and imprecision).  No studies of multicomponent interventions reported data on new diagnoses of dementia.  Multicomponent interventions may result in a small reduction of around a day in the duration of a delirium episode (mean difference (MD) -0.93, 95% CI -2.01 to 0.14 days, I² = 65%; 351 participants; low-certainty evidence downgraded due to risk of bias and imprecision). The evidence is very uncertain about the effect of multicomponent interventions on delirium severity (standardised mean difference (SMD) -0.49, 95% CI -1.13 to 0.14, I²=64%; 147 participants; very low-certainty evidence downgraded due to risk of bias and serious imprecision). Multicomponent interventions may result in a reduction in hospital length of stay compared to usual care (MD -1.30 days, 95% CI -2.56 to -0.04 days, I²=91%; 3351 participants; low-certainty evidence downgraded due to risk of bias and inconsistency), but little to no difference in new care home admission at the time of hospital discharge (RR 0.77, 95% CI 0.55 to 1.07; 536 participants; low-certainty evidence downgraded due to risk of bias and imprecision). Reporting of other adverse outcomes was limited.  Our exploratory component network meta-analysis found that re-orientation (including use of familiar objects), cognitive stimulation and sleep hygiene were associated with reduced risk of incident delirium. Attention to nutrition and hydration, oxygenation, medication review, assessment of mood and bowel and bladder care were probably associated with a reduction in incident delirium but estimates included the possibility of no benefit or harm.  Reducing sensory deprivation, identification of infection, mobilisation and pain control all had summary estimates that suggested potential increases in delirium incidence, but the uncertainty in the estimates was substantial.  Evidence from two trials suggests that use of a liberal transfusion threshold over a restrictive transfusion threshold probably results in little to no difference in incident delirium (RR 0.92, 95% CI 0.62 to 1.36; I² = 9%; 294 participants; moderate-certainty evidence downgraded due to risk of bias).  Six other interventions were examined, but evidence for each was limited to single studies and we identified no evidence of delirium prevention.  AUTHORS' CONCLUSIONS: There is moderate-certainty evidence regarding the benefit of multicomponent non-pharmacological interventions for the prevention of delirium in hospitalised adults, estimated to reduce incidence by 43% compared to usual care. We found no evidence of an effect on mortality. There is emerging evidence that these interventions may reduce hospital length of stay, with a trend towards reduced delirium duration, although the effect on delirium severity remains uncertain. Further research should focus on implementation and detailed analysis of the components of the interventions to support more effective, tailored practice recommendations.

Family Caregivers' Experience of Patients With Delirium in Critical Care Units: A State-of-the-Science Integrative Review

BACKGROUND

Delirium as a sudden cognitive and behavioral change can be traumatic for family caregivers. An understanding of family caregivers' experiences with delirium in their loved one in an intensive care unit (ICU) will help clinicians provide family-centered care.

OBJECTIVE

To explore the impact of delirium on, and the needs of, family caregivers of ICU patients with delirium.

METHODS

A comprehensive search was done of literature in the PubMed, CINAHL, and Scopus databases published from 2000 to 2020. Primary studies written in English and done in critical care settings were included. Studies that did not focus on the family experience of delirium were excluded. Additional studies were identified by reviewing the reference lists of selected articles. Evidence was synthesized, and common themes were identified.

RESULTS

Among 210 studies, 7 were included after irrelevant and duplicate studies had been removed. Findings were categorized as (1) psychological impacts of a patient's delirium on family caregivers and (2) family caregivers' needs. Common psychological impacts included anxiety, depression, concern, fear, anger, uncertainty, shock, insecurity, and disappointment. Family caregivers reported needing informational and emotional support from, and effective communication with, health care professionals.

CONCLUSIONS

Family caregivers' health is crucial to ensuring the effectiveness of family engagement in delirium management. Future studies should consider family caregiver characteristics that could be used to predict psychological symptoms when caregivers are exposed to a patient's delirium and explore whether specific types of delirium cause more psychological impacts and needs among family caregivers than other types of delirium cause.

Preventing Delirium and Promoting Long-Term Brain Health: A Clinical Trial Design for the Perioperative Cognitive Enhancement (PROTECT) Trial

BACKGROUND

Perioperative neurocognitive disorders (PND), including postoperative delirium (POD), are common in older adults and, for many, precipitate functional decline and/or dementia.

OBJECTIVE

In this protocol, we describe a novel multidisciplinary, multicomponent perioperative intervention that seeks to prevent or reduce POD and associated cognitive decline.

METHODS

We will conduct a prospective, single-blind, pragmatic, randomized-controlled trial to compare our tailored multi-disciplinary perioperative pathway against current standard of care practices. We will recruit a total of 692 elective surgical patients aged 65 years or more and randomize them in a 1:1 design. Our perioperative intervention targets delirium risk reduction strategies by emphasizing the importance of early mobilization, nutrition, hydration, cognitive orientation, sensory aids, and avoiding polypharmacy. To promote healthy behavior change, we will provide a tailored psychoeducation program both pre- and postoperatively, focusing on cardiovascular and psychosocial risks for cognitive and functional decline.

RESULTS

Our primary outcome is the incidence of any PND (encapsulating POD and mild or major postoperative neurocognitive disorder) at three months postoperative. Secondary outcomes include any incidence of POD or neurocognitive disorder at 12 months. A specialized delirium screening instrument, the Confusion Assessment Method (3D-CAM), and a neuropsychological test battery, will inform our primary and secondary outcomes.

CONCLUSION

Delirium is a common and debilitating postoperative complication that contributes to the cognitive and functional decline of older adults. By adopting a multicomponent, multidisciplinary approach to perioperative delirium prevention, we seek to reduce the burden of delirium and subsequent dementia in older adults.

Non-Pharmacological Nursing Interventions for Prevention and Treatment of Delirium in Hospitalized Adult Patients: Systematic Review of Randomized Controlled Trials

Delirium is a common neurobehavioral complication in hospitalized patients that can occur in the acute phase and lead to poor long-term outcomes. The purpose of this study was to identify non-pharmacological nursing interventions for the prevention and treatment of delirium in hospitalized adult patients. We conducted a systematic review to synthesize the findings of published studies. We searched the PubMed, EMBASE, CINAHL, and Cochrane Library CENTRAL databases for randomized controlled trials in January 2021. We report this systematic review according to the PRISMA 2009 checklist. The study was registered on PROSPERO (CRD42021226538). Nine studies were systematically reviewed for non-pharmacological nursing interventions for the prevention and treatment of delirium. The types of non-pharmacological nursing interventions included multicomponent intervention, multidisciplinary care, multimedia education, music listening, mentoring of family caregivers concerning delirium management, bright light exposure, ear plugs, and interventions for simulated family presence using pre-recorded video messages. These results could help nurses select and utilize non-pharmacological nursing interventions for the prevention and treatment of delirium in clinical nursing practice.

Outcomes of lumbar spinal fusion in super-elderly patients aged 80 years and over: Comparison with patients aged 65 years and over, and under 80 years

Despite the increasing prevalence of spinal surgery in super-elderly (SE) patients, the outcomes and complication rates have not been fully elucidated. The purpose of this study was to compare the outcomes and complications of lumbar spinal fusion for degenerative lumbar spinal stenosis (DLSS) in SE patients aged 80 years and over with those in patients aged 65 years and over, and under 80 years.This study analyzed 160 patients who underwent spinal fusion for DLSS between January 2011 and November 2019. Thirty patients in the SE group (group SE, ≥80 years) and 130 patients in the elderly group (group E, ≥65 years and <80 years) were enrolled. The performance status was evaluated by preoperative American society of anesthesiologists (ASA) score. Visual analog scales for back pain (VAS-BP) and leg pain (VAS-LP), and Korean Oswestry disability index (K-ODI) were used to assess clinical outcomes preoperatively and 1 year postoperatively. Percent changes of VAS-BP, VAS-LP and K-ODI were also analyzed. Fusion rates were evaluated by computed tomography 6 months and 1 year postoperatively. Furthermore, bone mineral density, operative time, estimated blood loss, blood transfusion, hospital days, hospitalization in intensive care unit and postoperative complications were compared.The average age of group SE was 82.0 years and that of group E was 71.6 years. There were no differences in preoperative ASA score, preoperative or postoperative VAS BP and VAS-LP, bone mineral density, operative time, estimated blood loss, blood transfusion, hospital days, hospitalization in intensive care unit and fusion rates between the groups. Preoperative and postoperative K-ODI were higher in group SE than group E (all P < .05). However, percent changes of VAS-BP, VAS-LP and K-ODI showed no significant differences. Overall early and late complications were not significantly different between the groups; however postoperative delirium was more common in group SE than group E (P = .027). SE status was the only risk factor for postoperative delirium with odds ratio of 3.4 (P = .018).Spinal fusion surgery is considerable treatment to improve the quality of life of SE patients with DLSS, however careful perioperative management is needed to prevent postoperative delirium.

Non-pharmacological interventions for preventing delirium in hospitalised non-ICU patients

BACKGROUND

Delirium is an acute neuropsychological disorder that is common in hospitalised patients. It can be distressing to patients and carers and it is associated with serious adverse outcomes. Treatment options for established delirium are limited and so prevention of delirium is desirable. Non-pharmacological interventions are thought to be important in delirium prevention.  OBJECTIVES: To assess the effectiveness of non-pharmacological interventions designed to prevent delirium in hospitalised patients outside intensive care units (ICU).

SEARCH METHODS

We searched ALOIS, the specialised register of the Cochrane Dementia and Cognitive Improvement Group, with additional searches conducted in MEDLINE, Embase, PsycINFO, CINAHL, LILACS, Web of Science Core Collection, ClinicalTrials.gov and the World Health Organization Portal/ICTRP to 16 September 2020. There were no language or date restrictions applied to the electronic searches, and no methodological filters were used to restrict the search.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) of single and multicomponent non-pharmacological interventions for preventing delirium in hospitalised adults cared for outside intensive care or high dependency settings. We only included non-pharmacological interventions which were designed and implemented to prevent delirium.  DATA COLLECTION AND ANALYSIS: Two review authors independently examined titles and abstracts identified by the search for eligibility and extracted data from full-text articles. Any disagreements on eligibility and inclusion were resolved by consensus. We used standard Cochrane methodological procedures. The primary outcomes were: incidence of delirium; inpatient and later mortality; and new diagnosis of dementia. We included secondary and adverse outcomes as pre-specified in the review protocol. We used risk ratios (RRs) as measures of treatment effect for dichotomous outcomes and between-group mean differences for continuous outcomes. The certainty of the evidence was assessed using GRADE. A complementary exploratory analysis was undertaker using a Bayesian component network meta-analysis fixed-effect model to evaluate the comparative effectiveness of the individual components of multicomponent interventions and describe which components were most strongly associated with reducing the incidence of delirium.

MAIN RESULTS

We included 22 RCTs that recruited a total of 5718 adult participants. Fourteen trials compared a multicomponent delirium prevention intervention with usual care. Two trials compared liberal and restrictive blood transfusion thresholds. The remaining six trials each investigated a different non-pharmacological intervention. Incidence of delirium was reported in all studies.  Using the Cochrane risk of bias tool, we identified risks of bias in all included trials. All were at high risk of performance bias as participants and personnel were not blinded to the interventions. Nine trials were at high risk of detection bias due to lack of blinding of outcome assessors and three more were at unclear risk in this domain.  Pooled data showed that multi-component non-pharmacological interventions probably reduce the incidence of delirium compared to usual care (10.5% incidence in the intervention group, compared to 18.4% in the control group, risk ratio (RR) 0.57, 95% confidence interval (CI) 0.46 to 0.71, I2 = 39%; 14 studies; 3693 participants; moderate-certainty evidence, downgraded due to risk of bias).  There may be little or no effect of multicomponent interventions on inpatient mortality compared to usual care (5.2% in the intervention group, compared to 4.5% in the control group, RR 1.17, 95% CI 0.79 to 1.74, I2 = 15%; 10 studies; 2640 participants; low-certainty evidence downgraded due to inconsistency and imprecision).  No studies of multicomponent interventions reported data on new diagnoses of dementia.  Multicomponent interventions may result in a small reduction of around a day in the duration of a delirium episode (mean difference (MD) -0.93, 95% CI -2.01 to 0.14 days, I2 = 65%; 351 participants; low-certainty evidence downgraded due to risk of bias and imprecision). The evidence is very uncertain about the effect of multicomponent interventions on delirium severity (standardised mean difference (SMD) -0.49, 95% CI -1.13 to 0.14, I2=64%; 147 participants; very low-certainty evidence downgraded due to risk of bias and serious imprecision). Multicomponent interventions may result in a reduction in hospital length of stay compared to usual care (MD -1.30 days, 95% CI -2.56 to -0.04 days, I2=91%; 3351 participants; low-certainty evidence downgraded due to risk of bias and inconsistency), but little to no difference in new care home admission at the time of hospital discharge (RR 0.77, 95% CI 0.55 to 1.07; 536 participants; low-certainty evidence downgraded due to risk of bias and imprecision). Reporting of other adverse outcomes was limited.  Our exploratory component network meta-analysis found that re-orientation (including use of familiar objects), cognitive stimulation and sleep hygiene were associated with reduced risk of incident delirium. Attention to nutrition and hydration, oxygenation, medication review, assessment of mood and bowel and bladder care were probably associated with a reduction in incident delirium but estimates included the possibility of no benefit or harm.  Reducing sensory deprivation, identification of infection, mobilisation and pain control all had summary estimates that suggested potential increases in delirium incidence, but the uncertainty in the estimates was substantial.  Evidence from two trials suggests that use of a liberal transfusion threshold over a restrictive transfusion threshold probably results in little to no difference in incident delirium (RR 0.92, 95% CI 0.62 to 1.36; I2 = 9%; 294 participants; moderate-certainty evidence downgraded due to risk of bias).  Six other interventions were examined, but evidence for each was limited to single studies and we identified no evidence of delirium prevention.  AUTHORS' CONCLUSIONS: There is moderate-certainty evidence regarding the benefit of multicomponent non-pharmacological interventions for the prevention of delirium in hospitalised adults, estimated to reduce incidence by 43% compared to usual care. We found no evidence of an effect on mortality. There is emerging evidence that these interventions may reduce hospital length of stay, with a trend towards reduced delirium duration, although the effect on delirium severity remains uncertain. Further research should focus on implementation and detailed analysis of the components of the interventions to support more effective, tailored practice recommendations.

Where should patients with or at risk of delirium be treated in an acute care system? Comparing the rates of delirium in patients receiving usual care vs alternative care: A systematic review and meta-analysis

BACKGROUND

Delirium is an acute condition that occurs in hospitalised patients and leads to poor patient outcomes that can last long term. Therefore, the importance of prevention is undeniable and adopting new models of care for at-risk patients should be prioritised.

OBJECTIVES

This systematic review and meta-analysis will assess the effectiveness of different interventions designed to prevent or manage delirium in acutely unwell hospitalised patients.

METHODS

MEDLINE, EMBASE, PsycINFO, OpenGrey, Web of Science and reference lists of journals were searched. Eligible studies reported on incidence or duration of delirium, used a validated delirium diagnostic tool and compared an intervention to either a control or another intervention group. Meta-analyses were conducted, and GRADEpro software was used to assess the certainty of evidence. This review is registered on PROSPERO.

RESULTS

A total of 59 studies were included and 33 were eligible for meta-analysis. Delirium incidence was most significantly reduced by non-pharmacological multicomponent interventions compared with usual care, with pooled risk ratios of 0.57 (95% CI: 0.44 to 0.73, 10 randomised controlled trials) and 0.47 (95% CI: 0.35 to 0.64, six observational studies). Single-component interventions did not significantly reduce delirium incidence compared with usual care in seven randomised trials (risk ratio = 0.92, 95% CI: 0.81 to 1.04). The most effective single-component intervention in reducing delirium incidence was a hospital-at-home intervention (risk ratio = 0.29, 95% CI: 0.09 to 0.87).

CONCLUSIONS

Non-pharmacological multicomponent interventions are effective in preventing delirium; however, the same cannot be said for other interventions because of uncertain results. There is some evidence that providing multicomponent interventions in patients' homes is more effective than in a hospital setting. Therefore, researching the benefits of hospital-at-home interventions in delirium prevention is recommended.

Improving Delirium Care in Hospitalized Older Adults: Impact of Education on Hospital Aides as Sitters

As one of several hospital team members involved in the management of care for older adults with delirium, hospital aides (HAs) are often relied on to provide direct patient care in the role of a sitter. Yet, many HAs have not received training about delirium, its associated behaviors, or appropriate interventions. As a consequence, there are gaps in quality of care for older adults with delirium and potential missed opportunities for HA sitters to contribute to the interdisciplinary team (IDT) care of these patients. In the current study, a quality improvement project at an urban hospital provided an educational session on delirium to HAs. Accuracy of HA delirium knowledge, delirium behavior recognition, and delivery of care to patients with delirium significantly increased across three postintervention measures (p = <0.001 to 0.016). HAs also reported increased confidence in caring for patients with delirium and in their perceived role on the IDT. [Journal of Gerontological Nursing, 47(6), 20-26.].

The family in preventing delirium in the intensive care unit: Scoping review

INTRODUCTION

Delirium is cognitive impairment related to negative inpatient outcomes in the Intensive Care Unit (ICU), family interventions have been shown to be effective in reducing the incidence of this condition.

OBJECTIVE

To identify strategies that include the family in the prevention of delirium in the adult intensive care unit that can be integrated into ABCDEF.

INCLUSION CRITERIA

Studies describing actions and interventions involving caregivers and family members in the ICU for the prevention of delirium, conducted in the last five years, available in full text, in English and Spanish, Portuguese and in adults.

METHODS

A scope review was conducted using the keywords "Critical Care, Delirium, Family, Primary Prevention" in 11 databases (PubMed, Virtual Health Library, Cochrane Library, TRIP Data base, EBSCO, Ovid Nursing, Springer, Scopus, Dialnet, Scielo, Lilacs) and other sources (Open Gray, Google Scholar), between August - October 2019; 8 studies were considered relevant and were analysed.

RESULTS

The results were described in 3 categories: flexibility vs. restriction of visits in the ICU, Reorientation as a prevention strategy and post-ICU syndrome in the family.

CONCLUSION

Extended visits, development of family-mediated activities, and redirection are non-pharmacological strategies that reduce the incidence of delirium in the ICU and offer multiple benefits to the patient and family/caregiver.

Identifying and Responding to Delirium in Acute Stroke: Clinical Team Members' Understandings

Delirium is associated with increased mortality, morbidity, and length of hospital stay. In the acute stroke setting, delirium identification is challenging due to the complexity of cognitive screening in this patient group. The aim of this study was to explore how members of interprofessional stroke-unit teams identified and responded to a potential delirium in a patient. Online focus groups and interviews utilizing case vignettes were conducted with 15 participants: nurses, occupational therapists, speech and language therapists, and physiotherapists working in acute stroke services. Participants' understandings of delirium varied, most participants did not identify the symptoms of a possible hypoactive delirium, and nearly all participants discussed delirium symptoms in tentative terms. Aspects of interprofessional working were discussed through the expression of distinct roles around delirium identification. Although participants demonstrated an ethos of person-focused care, there are ongoing challenges involved in early identification and management of delirium in stroke survivors.

Mobility Action Group: Using Quality Improvement Methods to Create a Culture of Hospital Mobility

BACKGROUND/OBJECTIVES

To describe the Mobility Action Group (MACT), an innovative process to enhance implementation of hospital mobility programs and create a culture of mobility in acute care.

DESIGN

Continuous quality improvement intervention with episodic data review.

SETTING

Inpatient units including medical, surgical, and intensive care settings.

PARTICIPANTS

A total of 42 hospitals of varying sizes across the United States.

INTERVENTIONS

The MACT and Change Package were developed to provide a conceptual framework, road map, and step-by-step guide to enable mobility teams to implement mobility programs successfully and meet their mobilization goals. Participants were encouraged to select two to three change tactics to pursue during the first action cycle and select and implement additional tactics in subsequent cycles. Nine learning sessions were held via webinar from April 27, 2017, to October 5, 2017, during which faculty provided brief presentations, facilitation, and group discussion.

MEASUREMENTS

Implementation of programs, walks per day, use of bed and chair alarms, and participant satisfaction.

RESULTS

Successful implementation of mobility programs was achieved at most (76%) sites. The proportion of patients who received at least three walks per day increased from 9% to 19%. The proportion of patients who were placed on a bed or chair alarm decreased from 36% to 20%. On average, 69% of participants reported they were "strongly satisfied" with the learning sessions. Most participants found the Change Package (58%) and Toolkit (63%) "very helpful." Since the conclusion of the active initiative, the Change Package has been downloaded 1,200 times. Of those who downloaded it, 48% utilized it to establish a mobility program, and 58% used it at their organization at least once a month.

CONCLUSION

The MACT and Change Package provides an innovative approach emphasizing systemwide change that can help catalyze a culture of mobility in hospitals across the nation, improving the quality of care for hospitalized older adults. J Am Geriatr Soc 68:2373-2381, 2020.

Managing delirium in terminally ill patients: perspective of palliative care nurse specialists

Delirium occurs frequently at end of life. Palliative care clinical nurse specialists (CNSs) are involved in community palliative care provision. Many patients prefer being cared for at home, yet managing delirium in this setting presents unique challenges, potentially resulting in emergency hospital or hospice admission. We examined the experiences and practice of palliative care CNSs managing delirium in the community; 10 interviews were undertaken. Data were analysed using the framework approach. Challenges to delirium management in the community included limited time with patients, reliance on families and access to medications. Assessment tools were not used routinely; time limited visits and inconsistent retesting were perceived barriers. Management approaches differed depending on CNSs' previous delirium education. Strategies to prevent delirium were not used. Community delirium management presents challenges; support surrounding these could be beneficial. Routine assessment tool use and delirium prevention strategies should be included in further education and research.

Design of a randomized placebo controlled trial of high dose intravenous thiamine for the prevention of delirium in allogeneic hematopoietic stem cell transplantation

BACKGROUND

Delirium is a highly prevalent and preventable neuropsychiatric condition with major health consequences. Thiamine deficiency is a well-established cause of delirium in those with chronic, severe alcoholism, but there remains an underappreciation of its significance in non-alcoholic populations, including patients with cancer. Treatment of suspected thiamine-related mental status changes with high dose intravenous (IV) thiamine has preliminary evidence for improving a variety of cognitive symptoms in oncology inpatient settings but has never been studied for the prevention of delirium in any population.

OBJECTIVES

The primary objective of this clinical trial is to determine if high dose IV thiamine can prevent delirium in patients receiving allogeneic hematopoietic stem cell transplantation (HSCT) for treatment of cancer. Secondary objectives are to determine if thiamine status is predictive of delirium onset and if high dose IV thiamine can attenuate the deleterious impact of delirium on health-related quality of life (HRQOL), functional status, and long-term neuropsychiatric outcomes.

METHODS

In this phase II study, we are recruiting 60 patients undergoing allogeneic HSCT, randomizing them to treatment with high dose IV thiamine (n = 30) versus placebo (n = 30), and systematically evaluating all participants for delirium and related comorbidities. We use the Delirium Rating Scale to measure the severity and duration of delirium during hospitalization for HSCT. We obtain thiamine levels weekly during the transplantation hospitalization. We assess HRQOL, functional status, depression, post-traumatic stress symptoms, and cognitive function prior to and at one, three, and six months after transplantation.

Non-Pharmacologic Multicomponent Interventions Preventing Delirium in Hospitalized People

BACKGROUND/OBJECTIVES

Delirium is a common neurobehavioral complication in hospitalized patients with a high prevalence in various clinical settings. Prevention of delirium is critical due to its common occurrence and associated poor outcomes. Our objective was to evaluate the efficacy of multicomponent interventions in preventing incident delirium in hospitalized patients at risk.

DESIGN

Systematic review and meta-analysis.

SETTING

Hospital.

PARTICIPANTS

We included a study if it was a randomized controlled trial and was evaluating effects of coordinated non-pharmacologic multicomponent interventions in the prevention of delirium.

MEASUREMENTS

We performed a systematic literature search in PubMed and CENTRAL (PROSPERO: CRD42019138981; last update May 24, 2019). We assessed the quality of included studies by using the criteria established by the Cochrane Collaboration. We extracted the measured outcomes for delirium incidence, duration of delirium, length of hospital stay, falls during hospital stay, discharge to institutional care, and inpatient mortality.

RESULTS

In total, we screened 1,027 eligible records and included eight studies with 2,105 patients in the review. We found evidence of an effect (ie, reduction) of multicomponent interventions on the incidence of delirium (risk ratio = .53; 95% confidence interval = .41-.69; I² = 0). We detected no clear evidence of an effect for delirium duration, length of hospital stay, accidental falls, and mortality. Subgroup analyses did not result in findings of substantial effect modifiers, which can be explained by the high homogeneity within studies.

CONCLUSION

Our findings confirm the current guidelines that multicomponent interventions are effective in preventing delirium. Data are still lacking to reach evidence-based conclusions concerning potential benefits for hard outcomes such as length of hospital stay, return to independent living, and mortality.

"You've got to keep moving, keep going": Understanding older patients' experiences and perceptions of delirium and nonpharmacological delirium prevention strategies in the acute hospital setting

AIMS AND OBJECTIVES

To explore older inpatients' experiences and perceptions of delirium and nonpharmacological delirium prevention strategies (NDPS).

BACKGROUND

Delirium is a distressing and serious complication in hospitalised older adults. NDPS (supporting nutrition, mobility and cognitive participation) have strong supporting evidence. Few studies have explored older inpatients' perspectives of these strategies. This information may assist staff to better support patient participation in NDPS.

DESIGN

Qualitative study using an interpretive descriptive (ID) methodological approach to explore older patient's experience of delirium and NDPS.

METHODS

Structured interviews of inpatients aged over 65 years across 6 medical and surgical wards explored patients' experiences and perceptions of delirium and prevention activities related to nutrition, mobility and cognition; and barriers and enablers to participation. Reporting used COREQ.

RESULTS

Twenty-three participants were included (12 male, 11 reported delirium experience). Participants reported a range of physiological, emotional and psychological responses to delirium, hearing about delirium was different to experiencing it. Most participants were aware of the benefits of maintaining nutrition and hydration, physical activity and cognitive engagement in hospital. Barriers included poor symptom control, inflexible routines and inconsistent communication, whilst enablers included access to equipment, family involvement, staff encouragement and individual goals. These were organised into themes: outlook, feeling well enough, hospital environment, feeling informed and listened to, and support networks.

CONCLUSION

A more patient-centred approach to delirium prevention requires consideration of older people's values, needs, preferences and fit within the hospital environment and routines. Feeling informed, listened to and receiving support from staff and family carers can improve older inpatients' engagement in NPDS to prevent delirium in hospital.

RELEVANCE TO CLINICAL PRACTICE

Nurses are ideally placed to improve patient participation in NDPS through holistic assessment and care, addressing symptoms, providing clear information about delirium and delirium prevention, and facilitating family carer support and patient interactions.

Effectiveness of non-pharmacological strategies for managing delirium in hospitalized postoperative adults: an umbrella review protocol

REVIEW QUESTION/OBJECTIVE

The question of this review: What is the effectiveness of non-pharmacological strategies for the management of delirium in hospitalized adult postoperative patients?The objective of this umbrella review is to determine the effectiveness of non-pharmacological strategies for the management of delirium in adult postoperative patients, 18 years and over, in an acute care hospitalized setting.More specifically, the review aims to identify which non-pharmacological strategy/strategies, provided as a single strategy or combined as two or more strategies, is the most effective for management of delirium in hospitalized postoperative adult patients?

Impact of a delirium prevention project among older hospitalized patients who underwent orthopedic surgery: a retrospective cohort study

Background

Postoperative delirium (POD) is a common clinical syndrome with significant negative outcomes. Thus, we aimed to evaluate the feasibility and effectiveness of a delirium screening tool and multidisciplinary delirium prevention project.

Methods

A retrospective cohort study was conducted at a single teaching center in Korea. A cohort of patients who underwent a delirium prevention program using a simple delirium screening tool from December 2018 to February 2019 (intervention group, N = 275) was compared with the cohort from the year before implementation of the delirium prevention program (December 2017 to February 2018) (control group, N = 274). Patients aged ≥65 years who were admitted to orthopedic wards and underwent surgery were included. The incidence rates of delirium before and after implementation of the delirium prevention program, effectiveness of the delirium screening tool, change in the knowledge score of nurses, and length of hospital stay were assessed.

Results

The sensitivity and specificity of the screening tool for the incidence of POD were 94.1 and 72.7%, respectively. The incidence rates of POD were 10.2% (control group) and 6.2% (intervention group). The odds ratio for the risk reduction effect of the project related to the incidence of POD was 0.316 (95% confidence interval: 0.125–0.800, p = 0.015) after adjustment for possible confounders. The delirium knowledge test score increased from 40.52 to 43.24 out of 49 total points (p < 0.001). The median length of hospital stay in the intervention and control groups was 6.0 (interquartile range, 4–9) and 7.0 (interquartile range, 4–10) days, respectively (p = 0.062).

Conclusion

The screening tool successfully identified patients at a high risk of POD at admission. The POD prevention project was feasible to implement, effective in preventing delirium, and improved knowledge regarding delirium among the medical staff.

Trial registration

Multicomponent, nonpharmacological delirium interventions for older inpatients : A scoping review

Background

Older people represent a risk group for acquiring or further development of delirium during hospitalization, therefore requiring suitable nonpharmacological delirium interventions.

Objective

This scoping review analyzed nonpharmacological intervention programs for older inpatients with or without cognitive decline on regular or acute geriatric wards to present the range of interventions.

Methods

A systematic literature search was conducted using scientific databases. A total of 4652 records were screened by two independent reviewers, leaving 81 eligible articles for full-text screening and 25 studies were finally included. Inclusion criteria were older patients ≥65 years in regular or acute geriatric wards and nonpharmacological multicomponent interventions.

Results

More than a half of the included studies (14, 56%) recruited patients with pre-existing cognitive decline as part of the study population and 12% focused exclusively on patients with cognitive decline. On average 11 intervention components were integrated in the programs and two programs included full coverage of all 18 identified components.

Conclusion

Only few programs were described for older inpatients and even fewer regarding pre-existing cognitive decline. The low numbers of interventions and data heterogeneity restricted the assessment of outcomes; however, delirium incidence, as reported by two thirds of the studies was reduced by nonpharmacological multicomponent interventions.

Inclusion, characteristics and outcomes of people requiring palliative care in studies of non-pharmacological interventions for delirium: A systematic review

BACKGROUND

Delirium is common, distressing, serious and under-researched in specialist palliative care settings.

OBJECTIVES

To examine whether people requiring palliative care were included in non-pharmacological delirium intervention studies in inpatient settings, how they were characterised and what their outcomes were.

DESIGN

Systematic review (PROSPERO 2017 CRD42017062178).

DATA SOURCES

Systematic search in March 2017 for non-pharmacological delirium intervention studies in adult inpatients. Database search terms were 'delirium', 'hospitalisation', 'inpatient', 'palliative care', 'hospice', 'critical care' and 'geriatrics'. Scottish Intercollegiate Guidelines Network methodological checklists guided risk of bias assessment.

RESULTS

The 29 included studies were conducted between 1994 and 2015 in diverse settings in 15 countries (9136 participants, mean age = 76.5 years (SD = 8.1), 56% women). Most studies tested multicomponent interventions (n = 26) to prevent delirium (n = 19). Three-quarters of the 29 included studies (n = 22) excluded various groups of people requiring palliative care; however, inclusion criteria, participant diagnoses, illness severity and mortality indicated their presence in almost all studies (n = 26). Of these, 21 studies did not characterise participants requiring palliative care or report their specific outcomes (72%), four reported outcomes for older people with frailty, dementia, cancer and comorbidities, and one was explicitly focused on people receiving palliative care. Study heterogeneity and limitations precluded definitive determination of intervention effectiveness and only allowed interpretations of feasibility for people requiring palliative care. Acceptability outcomes (intervention adverse events and patients' subjective experience) were rarely reported overall.

CONCLUSION

Non-pharmacological delirium interventions have frequently excluded and under-characterised people requiring palliative care and infrequently reported their outcomes.

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.

Etiology and Related Factors of Postoperative Delirium in Orthopedic Surgery

Background

Delirium is a serious complication for elderly patients after orthopedic surgery. The purpose of this study was to assess the etiology and related factors of delirium after orthopedic surgery in Korea.

Methods

We retrospectively reviewed the medical records of 3,611 patients over 50 years who had orthopedic surgery. The age of patients (50s, 60s, 70s, and > 80s), type of anesthesia (general, spinal, and local), operation time (more than 2 hours vs. less than 2 hours), surgical site (spine, hip, knee, or others), and etiology (trauma or disease) were compared to determine possible risk factors of delirium after orthopedic surgery.

Results

Of 3,611 patients, 172 (4.76%) were diagnosed with delirium after orthopedic surgery. Postoperative delirium occurred in 1.18% in their 50s, 3.86% in their 60s, 8.49% in their 70s, and 13.04% in > 80s (p < 0.001). According to anesthesia type, 6.50% of postoperative delirium occurred after general anesthesia, 0.77% after spinal anesthesia, and 0.47% after local anesthesia (p < 0.001). More than 2 hours of operation was associated with higher occurrence of delirium than less than 2 hours was (5.88% vs. 4.13%, p = 0.017). For the etiology, 8.17% were trauma cases and 3.02% were disease (p < 0.001). Postoperative delirium occurred in 22 of 493 patients (4.46%) after spine surgery, 18 of 355 patients (5.07%) after hip surgery, 17 of 394 patients (4.31%) after knee surgery, and 15 of 1,145 patients (1.31%) after surgery at other sites (p < 0.001).

Conclusions

Postoperative delirium was more common in older patients who had surgery under general anesthesia, whose surgery took more than 2 hours, and who were hospitalized through the emergency room.

Characteristics of Hospitalized Patients Screening Positive for Delirium

BACKGROUND

Delirium in the hospitals leads to worse outcomes for patients. There were no previous studies that characterize patients with delirium from multiple hospital locations.

OBJECTIVE

To describe patient characteristics screening positive for delirium and identify any correlations with hospital location and medication use.

DESIGN, SETTINGS, PATIENTS

Retrospective chart review of 227 hospitalized patients from a large, academic, tertiary referral, 2-campus health system. Patients were ≥18 years old and had delirium for at least ≥24 hours. Validated delirium screening tools were utilized.

MEASUREMENTS

Patients' demographics, inpatient stay information, delirium episodes characteristics, drugs, and palliative and psychiatry teams' involvement.

RESULTS

Most patients were older with a mean age of 64.1 years. The most common primary diagnoses were infection, cardiac, and pulmonary. Average length of delirium was 7.2 days (standard deviation [SD] = 8.2), and average length of stay (LOS) was 18.7 days (median = 10.5, SD = 35.1, 95% confidence interval = 14.1-23). Thirty-day readmission rate was 24.8% (65/262 hospitalizations); 12.8% of patients died in the hospital (29/227). Around one-third of hospitalizations had involvement of palliative care, palliative psychiatry, or general psychiatry team. There was a decrease in the number of medications administered 24 hours after the first recording of delirium compared to the immediate preceding 48 hours. Those hospitalizations where delirium first occurred in the intensive care unit (ICU) did have a longer LOS (average = 22.9, SD = 45.7) than those where delirium first occurred outside the ICU (average = 14.8, SD = 20.5). Patients were likely to have received an opioid within 48 hours in 51% of hospitalizations and to have received benzodiazepines in 16% of hospitalizations.

CONCLUSION

In our study, we found that delirium significantly impacted length of delirium episode, number of episodes of delirium, length of hospital admission, and mortality. The population most sensitive to the impacts of delirium were elderly patients.
