A Toolkit for Delirium Identification and Promoting Partnerships Between Carers and Nurses: A Pilot Pre-Post Feasibility Study. J Gen Intern Med 2024; 39:2001-2008. [PMID: 38647970 PMCID: PMC11306898 DOI: 10.1007/s11606-024-08734-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2023] [Accepted: 03/15/2024] [Indexed: 04/25/2024]
Abstract
BACKGROUND Delirium is frightening for people experiencing it and their carers, and it is the most common hospital-acquired complication worldwide. Delirium is associated with higher rates of morbidity, mortality, residential care home admission, dementia, and carer stress and burden, yet strategies to embed the prevention and management of delirium as part of standard hospital care remain challenging. Carers are well placed to recognize subtle changes indicative of delirium, and partner with nurses in the prevention and management of delirium. OBJECTIVE To evaluate a Prevention & Early Delirium Identification Carer Toolkit (PREDICT), to support partnerships between carers and nurses to prevent and manage delirium. DESIGN A pre-post-test intervention and observation study. MAIN MEASURES Changes in carer knowledge of delirium; beliefs about their role in partnering with nurses and intended and actual use of PREDICT; carer burden and psychological distress. Secondary measures were rates of delirium. PARTICIPANTS Participants were carers of Indigenous patients aged 45 years and older and non-Indigenous patients aged 65 years and older. INTERVENTION Nurses implemented PREDICT, with a view to provide carers with information about delirium and strategies to address caregiving stress and burden. KEY RESULTS Participants included 25 carers (43% response rate) (n = 17, 68% female) aged 29-88 (M = 65, SD = 17.7 years). Carer delirium knowledge increased significantly from pre-to-post intervention (p = < .001; CI 2.07-4.73). Carers' intent and actual use of PREDICT was (n = 18, 72%; and n = 17, 68%). Carer burden and psychological distress did not significantly change. The incidence of delirium in the intervention ward although not significant, decreased, indicating opportunity for scaling up. CONCLUSION The prevention and management of delirium are imperative for safe and quality care for patients, carers, and staff. Further comprehensive and in-depth research is required to better understand underlying mechanisms of change and explore facets of nursing practice influenced by this innovative approach.

Abstract
BACKGROUND Traumatic brain injury (TBI) is a significant cause of mortality and morbidity worldwide. With survivors often exhibiting degrees of function loss, a significant burden is exerted on their caregivers. The purpose of this study was to explore the predictive factors of caregiver burden among caregivers of patients with TBI. METHODS Sixty-eight family members of individuals with a TBI who had been admitted to three hospitals were assessed in terms of caregiver burden using the Zarit Burden Interview. The association of caregiver burden with patients' baseline cognitive function according to the Montreal Cognitive Assessment (MoCA) test, as well as caregivers' sociodemographic characteristics, were evaluated using multiple regression analysis. RESULTS Based on the multiple regression model, the MoCA score of the patients (std β=-0.442, p < 0.001), duration of caregiving (std β = 0.228, p = 0.044), and higher education of the caregivers (std β = 0.229, p = 0.038) were significant predictors of caregiver burden. CONCLUSION Overall, our findings highlight the importance of taking caregivers' psychosocial needs into account. Long-term caregivers of TBI patients with cognitive impairment should be viewed as vulnerable individuals who could benefit from psychosocial intervention programs, to improve their well-being and enabling them to enrich their care of the TBI patient.

Abstract
Delirium is a significant geriatric condition associated with adverse clinical and economic outcomes. The cause of delirium is usually multifactorial, and person-centered multicomponent approaches for proper delirium management are required. In 2017, the John A. Hartford Foundation and the Institute for Healthcare Improvement (IHI) launched a national initiative, Age-Friendly Health System (AFHS), promoting the use of a framework called 4Ms (what matters, medication, mentation, and mobility). The 4Ms framework's primary goal is to provide comprehensive and practical person-centered care for older adults and it aligns with the core concepts of optimal delirium management. In this special article, we demonstrate how a traditional delirium prevention and management model can be assessed from the perspective of AFHS. An example is the crosswalk with the Hospital Elder Life Program (HELP) Core Interventions and the 4MS, which demonstrates alignment in delirium management. We also introduce useful tools to create an AFHS environment in delirium management. Although much has been written about delirium management, there is a need to identify the critical steps in advancing the overall delirium care in the context of the AFHS. In this article, we suggest future directions, including the need for more prospective and comprehensive research to assess the impact of AFHS on delirium care, the need for more innovative and sustainable education platforms, fundamental changes in the healthcare payment system for proper adoption of AFHS in any healthcare setting, and application of AFHS in the community for continuity of care for older adults with delirium.

Abstract
INTRODUCTION One-year health-care costs associated with delirium in older hospitalized patients with and without Alzheimer's disease and related dementias (ADRD) have not been examined previously. METHODS Medicare costs were determined prospectively at discharge, and at 30, 90, and 365 days in a cohort (n = 311) of older adults after hospital admission. RESULTS Seventy-six (24%) patients had ADRD and were more likely to develop delirium (51% vs. 24%, P < 0.001) and die within 1 year (38% vs. 21%, P = 0.002). In ADRD patients with versus without delirium, adjusted mean difference in costs associated with delirium were $34,828; most of the excess costs were incurred between 90 and 365 days (P = 0.03). In non-ADRD patients, delirium was associated with increased costs at all timepoints. Excess costs associated with delirium in ADRD patients increased progressively over 1 year, whereas in non-ADRD patients the increase was consistent across time periods. DISCUSSION Our findings highlight the complexity of health-care costs for ADRD patients who develop delirium, a potentially preventable source of expenditures. HIGHLIGHTS Novel examination of health-care costs of delirium in persons with and without Alzheimer's disease and related dementias (ADRD). Increased 1-year costs of $34,828 in ADRD patients with delirium (vs. without). Increased costs for delirium in ADRD occur later during the 365-day study period. For ADRD patients, cost differences between those with and without delirium increased over 1 year. For non-ADRD patients, the parallel cost differences were consistent over time.

Abstract
BACKGROUND Many individuals with Alzheimer's disease (AD) are dependent on nonprofessional care partners. Providing informal care can result in emotional, physical, and financial burdens; however, there is a need for a better understanding of the impact of AD on care partners to support the clinical and economic assessment of potential new treatments. OBJECTIVE We conducted a literature review to evaluate the burden experienced by care partners of individuals with AD. METHODS Electronic screening and supplementary searches identified studies published from 2011 to 2022 describing the association between AD and the quality of life (QoL) and physical health of care partners, and the economic or financial burden of AD. RESULTS Following electronic screening, 62, 25, and 39 studies were included on care partner burden, cost, and healthcare resource use in AD, respectively. Supplementary searches identified an additional 32 studies, resulting in 149 unique studies. These studies showed that care partners of individuals with AD report moderate to severe burden. Higher burden and lower QoL were observed in those caring for individuals with more severe AD. Care partners of individuals with AD experience higher burden, lower QoL, and higher levels of stress, depression, and anxiety than those without caring responsibilities. Informal care costs increased with AD severity and accounted for the greatest proportion of overall societal cost. CONCLUSIONS Care partners of individuals with AD experience emotional and economic burden, which increases with AD severity. These impacts should be quantified comprehensively in future studies and captured in economic evaluations of AD interventions.

Abstract
AIMS To explore experiences of family caregivers providing support to older persons with delirium superimposed on dementia in acute care hospitals, their role in detection and management of this condition, and support they require. DESIGN This study has an exploratory-descriptive design using interpretive description methodology. METHODS Semi-structured interviews were conducted with nine caregivers from January to April 2020. Interview transcripts underwent thematic analysis. FINDINGS Three themes were identified: (1) family caregivers found delirium superimposed on dementia to be an overwhelming experience, (2) family caregivers can play an important role in the detection and management of delirium superimposed on dementia and (3) family caregivers' experiences were influenced by the nature of their relationship with the health care team. Family caregivers found the experience distressing and felt unprepared to face the condition. Family caregivers also possessed knowledge helpful in detecting acute changes and caring for the older person. Family caregivers' relationships with the health care team varied: some felt supported by the team, while others experienced a power imbalance, characterized by lack of communication and opportunities to participate in care. CONCLUSIONS Family caregivers were distressed to see family members hospitalized with delirium superimposed on dementia. Family caregivers are also ideally positioned to detect the condition and participate in care. However, power imbalances remain, leaving family caregivers feeling disempowered and believing the health care team had more control over the older person's care. IMPACT Findings highlight the need for strategies to address the distress and disempowerment experienced by family caregivers of hospitalized older persons with delirium superimposed on dementia. By building collaborative relationships, nurses and other health care team members can help family caregivers navigate the complex experience with delirium superimposed on dementia and reduce distress, with the ultimate goal of facilitating family caregivers' ability to care for older persons in the community. NO PATIENT OR PUBLIC CONTRIBUTION While the study participants are members of the public, this population was not involved in the study design and analysis. This method aligns with interpretive description, where researchers are not just a medium through which participants speak, but also interpretive instruments who discern insights not accessible to persons who may be familiar with only a single case.

Abstract
OBJECTIVE To validate a previously published machine learning model of delirium risk in hospitalized patients with coronavirus disease 2019 (COVID-19). METHOD Using data from six hospitals across two academic medical networks covering care occurring after initial model development, we calculated the predicted risk of delirium using a previously developed risk model applied to diagnostic, medication, laboratory, and other clinical features available in the electronic health record (EHR) at time of hospital admission. We evaluated the accuracy of these predictions against subsequent delirium diagnoses during that admission. RESULTS Of the 5102 patients in this cohort, 716 (14%) developed delirium. The model's risk predictions produced a c-index of 0.75 (95% CI, 0.73-0.77) with 27.7% of cases occurring in the top decile of predicted risk scores. Model calibration was diminished compared to the initial COVID-19 wave. CONCLUSION This EHR delirium risk prediction model, developed during the initial surge of COVID-19 patients, produced consistent discrimination over subsequent larger waves; however, with changing cohort composition and delirium occurrence rates, model calibration decreased. These results underscore the importance of calibration, and the challenge of developing risk models for clinical contexts where standard of care and clinical populations may shift.

Abstract
The current study examined the association of patient factors, patient/caregiver relationships, and living arrangements with caregiver burden due to delirium. The sample included a subset (N = 207) of hospitalized medical and surgical patients (aged >70 years) enrolled in the Better Assessment of Illness Study and their care-givers. The majority of caregivers were female (57%) and married (43%), and 47% reported living with the patient. Delirium occurred in 22% of the sample, and delirium severity, pre-existing cognitive impairment, and impairment of any activities of daily living (ADL) were associated with higher caregiver burden. However, only the ADL impairment of needing assistance with transfers was independently significantly associated with higher burden (p < 0.01). Child, child-in-law, and other relatives living with or apart from the patient reported significantly higher caregiver burden compared to spouse/partners (p < 0.01), indicating caregiver relationship and living arrangement are associated with burden. Future studies should examine additional factors contributing to delirium burden. [Journal of Gerontological Nursing, 47(9), 32-39.].

Abstract
OBJECTIVE Our aim was to measure the prevalence of delirium, its clinical features, and outcomes in older patients referred to a memory clinic. METHODS A retrospective cohort study of 109 older outpatients with delirium referred to a memory clinic with a home care service. Delirium was diagnosed using the confusion assessment method and dementia with the DSM-5 criteria. We collected information on cognitive and functional status, mortality, institutionalization, and hospitalization during 6 months following the delirium episode. RESULTS Delirium prevalence was 3.6%, mostly of hyperactive type. Delirium worsened functional (ADL 2.95 ± 1.95 vs. 2.16 ± 1.84) and cognitive (MMSE 13.88 ± 8.96 vs.11.0 ± 9.49) status after 6 months compared to the baseline. The mortality rate was 29.4%, and 28.3% were admitted to a long-term facility after the episode of delirium. Of these patients, more than half were hospitalized during the follow-up. Of the 109 patients with delirium, 85 were managed at home and 24 were hospitalized. Patients who were hospitalized had more severe behavioral symptoms during the delirium episode. There was no difference in mortality and institutionalization according to the home or hospital management. CONCLUSIONS This retrospective cohort study adds novel information to the existing literature of an understudied setting and population. The study supports the need to further investigate the feasibility and efficacy of the hospital at home models for the prevention and management of delirium in a high-risk population.

A core outcome set for studies evaluating interventions to prevent and/or treat delirium for adults requiring an acute care hospital admission: an international key stakeholder informed consensus study. BMC Med 2021; 19:143. [PMID: 34140006 PMCID: PMC8211534 DOI: 10.1186/s12916-021-02015-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/28/2021] [Accepted: 05/21/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Trials of interventions to prevent or treat delirium in adults in an acute hospital setting report heterogeneous outcomes. Our objective was to develop international consensus among key stakeholders for a core outcome set (COS) for future trials of interventions to prevent and/or treat delirium in adults with an acute care hospital admission and not admitted to an intensive care unit. METHODS A rigorous COS development process was used including a systematic review, qualitative interviews, modified Delphi consensus process, and in-person consensus using nominal group technique (registration http://www.comet - initiative.org/studies/details/796 ). Participants in qualitative interviews were delirium survivors or family members. Participants in consensus methods comprised international representatives from three stakeholder groups: researchers, clinicians, and delirium survivors and family members. RESULTS Item generation identified 8 delirium-specific outcomes and 71 other outcomes from 183 studies, and 30 outcomes from 18 qualitative interviews, including 2 that were not extracted from the systematic review. De-duplication of outcomes and formal consensus processes involving 110 experts including researchers (N = 32), clinicians (N = 63), and delirium survivors and family members (N = 15) resulted in a COS comprising 6 outcomes: delirium occurrence and reoccurrence, delirium severity, delirium duration, cognition, emotional distress, and health-related quality of life. Study limitations included exclusion of non-English studies and stakeholders and small representation of delirium survivors/family at the in-person consensus meeting. CONCLUSIONS This COS, endorsed by the American and Australian Delirium Societies and European Delirium Association, is recommended for future clinical trials evaluating delirium prevention or treatment interventions in adults presenting to an acute care hospital and not admitted to an intensive care unit.

Abstract
OBJECTIVE Delirium is a common condition associated with increased morbidity and mortality. Medication side effects are a possible source of modifiable delirium risk and provide an opportunity to improve delirium predictive models. This study characterized the risk for delirium diagnosis by applying a previously validated algorithm for calculating central nervous system adverse effect burden arising from a full medication list. METHOD Using a cohort of hospitalized adult (age 18-65) patients from the Massachusetts All-Payers Claims Database, we calculated medication burden following hospital discharge and characterized risk of new coded delirium diagnosis over the following 90 days. We applied the resulting model to a held-out test cohort. RESULTS The cohort included 62,180 individuals of whom 1.6% (1019) went on to have a coded delirium diagnosis. In the training cohort (43,527 individuals), the medication burden feature was positively associated with delirium diagnosis (OR = 5.75, 95% CI 4.34-7.63) and this association persisted (aOR = 1.95; 1.31-2.92) after adjusting for demographics, clinical features, prescribed medications, and anticholinergic risk score. In the test cohort, the trained model produced an area under the curve of 0.80 (0.78-0.82). This performance was similar across subgroups of age and gender. CONCLUSION Aggregating brain-related medication adverse effects facilitates identification of individuals at high risk of subsequent delirium diagnosis.

Abstract
Although dementia is the largest independent risk factor for delirium and leads to poor health outcomes, we know little about how to prevent delirium in persons with dementia (PWD). The purpose of the current systematic literature review was to identify interventions designed to prevent delirium in older PWD. Seven studies meeting inclusion criteria were extracted. Five studies were in the acute care setting and two were community settings. One study used a randomized controlled trial design. Five of the seven interventions comprised multiple components addressing delirium risk factors, including education. Two studies addressed delirium by administration of medication or vitamin supplementation. Using the GRADE framework for the evaluation of study quality, we scored three studies as moderate and four studies as low. Thus, high-quality research studies to guide how best to prevent delirium in PWD are lacking. Although more research is required, the current review suggests that multicomponent approaches addressing delirium risk factors should be considered by health care professionals when supporting older PWD.

Does Alzheimer's Disease and Related Dementias Modify Delirium Severity and Hospital Outcomes? J Am Geriatr Soc 2020; 68:1722-1730. [PMID: 32255521 DOI: 10.1111/jgs.16420] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2020] [Revised: 02/25/2020] [Accepted: 02/27/2020] [Indexed: 12/19/2022]
Abstract
OBJECTIVES We examined the association between delirium severity and outcomes of delirium among persons with and without Alzheimer's disease and related dementias (ADRD). DESIGN Prospective cohort study. SETTING Academic tertiary medical center. PARTICIPANTS A total of 352 medical and surgical patients. MEASUREMENTS Delirium incidence and severity were rated daily using the Confusion Assessment Method (CAM) and CAM-Severity (CAM-S) score during hospitalization. Severe delirium was defined as a CAM-S Short Form score in the highest tertile (3-7 points out of 7). ADRD status was determined by a clinical consensus process. Clinical outcomes included prolonged length of stay (>6 d), discharge to post-acute nursing facility, any decline in activities of daily living (ADLs) at 1 month from prehospital baseline, ongoing nursing facility stay, and mortality. RESULTS Patients with ADRD (n = 85 [24%]) had a significantly higher relative risk (RR) for incident delirium (RR = 2.31; 95% confidence interval [CI] = 1.64-3.28) and higher peak CAM-S scores (mean difference = 1.24 points; CI = .83-1.65; P < .001). Among patients with ADRD, severe delirium significantly increased the RR for nursing facility stay (RR = 2.22; CI = 1.05-4.69; P = .04) and increased the RR for mortality (RR = 2.10; CI = .89-4.98; P = .09). Among patients without ADRD, severe delirium was associated with a significantly increased risk for all poor outcomes except mortality including prolonged length of stay in the hospital (RR = 1.47; CI = 1.18-1.82) and discharge to a post-acute nursing facility (RR = 2.17; CI = 1.58-2.98) plus decline in ADLs (RR = 1.30; CI = 1.05-1.60) and nursing facility stay at 1 month (RR = 1.93; CI = 1.31-2.83). CONCLUSION Severe delirium is associated with increased risk for poor clinical outcomes in patients with and without ADRD. In both groups, severe delirium increased risk of nursing home placement. In patients with ADRD, delirium was more severe and associated with a trend toward increased mortality at 1 month. Although the increased risk remains substantial by RR, the study had limited power to examine the rarer outcome of death. J Am Geriatr Soc 68:1722-1730, 2020.
