Experiences, understandings and support needs of family carers of older patients with delirium: a descriptive mixed methods study in a hospital delirium unit

Experience of carers for older people with delirium: a qualitative study

OBJECTIVES

There is a gap in our understanding of the experiences and needs of carers for patients with delirium and a scarcity of research on the topic in the UK. This study aims to explore the needs and experiences of carers for person with delirium and offer suggestions to support them.

METHOD

A qualitative interview study with carers of patients with delirium. Data were analysed using an abductive analysis approach.

RESULTS

Fourteen carers were interviewed. We identified four themes; carers' involvement in providing care for the person with delirium, carers' perspectives of caregiving, support for carers and impact for caregiving on carers. Carers felt a responsibility to support the patient and to obtain information on delirium and its management on their own. Caregiving for a person with delirium had an emotional impact on the carer and they needed to change their lifestyle to maintain their caregiving responsibilities, as a result of the limited support they had.

CONCLUSION

More support for the carer in care plans with focus on emotional support, support groups for carers of people with delirium and assigning a case worker should be taken into consideration when developing interventions for people with delirium at home. These solutions may mitigate the impact of caregiving role on the mental and physical wellbeing of the carer for older person with delirium.

Delirium in the Acute Care Setting From the Families Perspective: A Scoping Review

AIM

To explore the existing literature on delirium within the acute care setting from the family members' perspective and summarise key findings.

DESIGN

A scoping review guided by Arksey and O'Malley's methodological framework and refined by the Joanna Briggs Institute.

REVIEW METHODS

The Population, Concept, and Context framework recommended by the Joanna Briggs Institute's scoping review protocol identified the main concepts in the primary review question. The inclusion criteria focused on primary research studies from any chronological date that explored the family members' experience of delirium within the acute care setting. Following screening by two independent reviewers, data extraction was conducted and presented in tabular form, detailing the study aim, sample, setting, methods, key findings and recommendations for future research and clinical practice.

DATA SOURCES

A comprehensive search was conducted in January 2025 using CINAHL+, MEDLINE, JBI, Cochrane Library, Web of Science, Scopus and Google Scholar. Citation searching and reference lists supplemented this review to identify relevant studies.

RESULTS

Seventeen studies met the inclusion criteria. Families' experiences of delirium were categorised into (1) lack of awareness and understanding of delirium; (2) communication and informational needs of family members regarding delirium; (3) the emotional impact delirium has on family members, and (4) family desire to participate in their loved one's care.

CONCLUSION

This review highlighted a paucity of literature addressing the experiences of family members who witness delirium in the acute care setting. The existing research underscored the need for clear communication and information regarding delirium to mitigate the negative emotional impact that delirium places on families.

IMPACT

This scoping review provides insights into the challenges facing families witnessing delirium in the acute care setting. A better understanding of family members' experiences can guide the development of a supported family-centred approach to delirium care.

PATIENT CONTRIBUTION

No patient/public contribution.

Family perspectives on delirium information provision in an inpatient setting

OBJECTIVES

Delirium is common in older hospitalised patients and is associated with significant distress in family members who witness it. Education-based interventions can support the family of people with delirium. This study aimed to understand the perspective of family members of people with delirium regarding the information they received and opportunities for improvement.

METHODS

We performed 10 semi-structured interviews of 11 family members (one mother-daughter dyad) of people with delirium greater than 65 years of age across two sub-acute Geriatric Evaluation and Management units in Victoria, Australia. Interviews were inductively analysed by the lead investigator to identify themes related to the information provided and opportunities for improvement.

RESULTS

We identified three themes related to delirium information provision: (1) delirium knowledge is not common; (2) information should consider the broad complex of the person; and (3) lived experience of delirium was helpful. We identified five themes with regard to opportunities to improve delirium information provision: (1) Good communication skills are important; (2) Regular communication is helpful; (3) Family wish to be present and know how to be involved; (4) Information provision should include prognosis; (5) Written information can support verbal information.

CONCLUSIONS

Information provision to family members should take into account their existing knowledge and experience and consider their family member as a whole. High quality, regular, written and oral communication from health-care professionals is likely to prove helpful.

Evaluation of the Quality of Delirium Website Content for Patient and Family Education: Cross-Sectional Study

BACKGROUND

Patients and families who have experienced delirium may seek information about delirium online, but the quality and reliability of online delirium-related websites are unknown.

OBJECTIVE

This study aimed to identify and evaluate online delirium-related websites that could be used for patient and family education.

METHODS

We searched Microsoft Bing, Google, and Yahoo using the keywords "delirium" and the misspelled "delerium" to identify delirium-related websites created to inform patients, families, and members of the public about delirium. The quality of identified delirium-related website content was evaluated by 2 authors using the validated DISCERN tool and the JAMA (Journal of the American Medical Association) benchmark criteria. Readability was assessed with the Simple Measure of Gobbledygook, the Flesch Reading Ease score, and the Flesch Kincaid grade level. Each piece of website content was assessed for its delirium-related information using a checklist of items co-designed by a working group, which included patients, families, researchers, and clinicians.

RESULTS

We identified 106 websites targeted toward patients and families, with most hospital-affiliated (21/106, 20%) from commercial websites (20/106, 19%), government-affiliated organizations (19/106, 18%), or from a foundation or advocacy group (16/106, 15%). The median time since the last content update was 3 (IQR 2-5) years. Most websites' content (101/106, 95%) was written at a reading level higher than the recommended grade 6 level. The median DISCERN total score was 42 (IQR 33-50), with scores ranging from 20 (very poor quality) to 78 (excellent quality). The median delirium-related content score was 8 (IQR 6-9), with scores ranging from 1 to 12. Many websites lacked information on the short- and long-term outcomes of delirium as well as how common it is. The median JAMA benchmark score was 1 (IQR 1-3), indicating the quality of the websites' content had poor transparency.

CONCLUSIONS

We identified high-quality websites that could be used to educate patients, families, or the public about delirium. While most delirium-related website content generally meets quality standards based on DISCERN and JAMA benchmark criteria, high scores do not always ensure patient and family-friendliness. Many of the top-rated delirium content were text-heavy and complex in layout, which could be overwhelming for users seeking clear, concise information. Future efforts should prioritize the development of websites with patients and families, considering usability, accessibility, and cultural relevance to ensure they are truly effective for delirium education.

Barriers to healthcare professionals recognizing and managing delirium in older adults during a hospital stay: A mixed-methods systematic review

AIM

To investigate barriers to healthcare professionals recognizing and managing delirium in hospitalized older people.

DESIGN

A mixed-methods systematic review.

PROSPERO ID

CRD42020187932.

DATA SOURCES

MEDLINE, EMBASE, PsycINFO and CINAHL were searched (2007 to February 2023).

REVIEW METHODS

Included studies focused on healthcare professionals' recognition and management of delirium for patients aged 65 years and over in a hospital ward or emergency department. Enhancing rigour, screening of results was conducted independently by two researchers. Qualitative and quantitative data were tabulated separately and grouped. Data were compared to identify similarities and differences. All studies were quality appraised.

RESULTS

43 studies were included; 24 quantitative, 16 qualitative and three mixed-methods. Data synthesis highlighted synergy between qualitative and quantitative findings. Barriers were reflected in six themes: (1) healthcare professionals' knowledge and understanding; (2) communication; (3) workforce development; (4) interprofessional working; (5) confounders; and (6) organizational constraints.

CONCLUSIONS

Of significance, for older adults in hospital experiencing delirium, there is variability in whether and how well it is recognized and managed. To prevent adverse outcomes best practice guidance for screening, recognizing, diagnosing and managing delirium in older people needs to be agreed and disseminated widely. Supporting healthcare professionals to care for this patient population using an integrated approach is essential, how to involve and communicate with patients and their family and friends, how to recognize and manage delirium for patients with additional needs, e.g., those living with dementia and/or a learning disability. Hospitals need to have policy and guidance in place for the recognition and management of delirium in older adults presenting to a ward or to an emergency department. An IT infrastructure is needed that integrates assessments and care management plans in patient electronic records and makes them accessible within and across teams in hospital, primary and community care settings.

PATIENT OR PUBLIC CONTRIBUTION

There was no patient or public contribution to this systematic review.

IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE

Healthcare professionals can be better supported to be able to recognize and manage delirium during an acute hospital stay for older adults. This includes maximizing best care for those patients living with dementia, involving families and friends to help understand patients' baseline status and changes and supporting families and friends during this process. Of significance, attention to hospital IT infrastructures is warranted, integrating screening, assessment and care management plans in patients' electronic records and making these accessible to healthcare professionals caring for this patient population across care settings.

IMPACT

What problem did the study address? Delirium is a common condition experienced by older hospitalized patients, but it is consistently under-recognized which has implications for patient and organization outcomes. To help address this, understanding barriers to healthcare professionals recognizing and managing delirium for this patient population is paramount. What were the main findings? Barriers to healthcare professionals recognizing and managing delirium for this patient population were synthesized in six themes: (1) healthcare professionals' knowledge and understanding, (2) communication; (3) workforce development; (4) interprofessional working; (5) confounders; and (6) organizational constraints. Where and on whom will the research have an impact? The findings of this original systematic review can contribute to hospital policy and protocol for the recognition and management of delirium in older patients. The findings can meaningfully contribute to workforce professional development for practitioners caring for older people during an acute hospital stay and for practitioners in primary and community settings involved in the follow-up of patients post hospital discharge. For researchers, the findings indicate several research recommendations including investigating the impact of an education programme for nurses and other healthcare professionals on the recognition and management of the condition and understanding and investigating how best to support delirium-related distress experienced by patients and their families and practitioners.

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.

Experiences of relatives of patients with delirium due to an acute health event - A systematic review of qualitative studies

OBJECTIVE

Evaluate relatives' experience of delirium due to an acute health event in a loved person and to compile practical suggestions for health care professionals from these synthesized results.

BACKGROUND

Delirium resulting from an acute health event places patients at increased risk for prolonged hospitalization and mortality. A delirium episode also affects family members who may assist in the diagnosis and recovery from this condition.

INCLUSION CRITERIA

Qualitative studies of family members or other caregivers who witnessed patient delirium in a clinical setting were included if they had appropriate verbatim evidence. Studies dealing exclusively with delirium in the context of dementia, cancer, palliative care, or drug dependence were excluded, and if quotes could not be clearly allocated to relatives.

METHODS

A systematic review of qualitative studies adapted from the Joanna Briggs Institute meta-aggregation approach. A systematic literature search was conducted in CINAHL complete®, MEDLINE®, and several dissertation databases in September 2022.

RESULTS

Eight qualitative studies based on semi-structured interviews were included. In total 75 findings from 105 relatives were aggregated into 13 categories. Finally, three synthesized findings reveal suggestions for health care professionals: providing information adequately, communication and integration during health care and understanding relatives' perspective on delirium experience.

CONCLUSION

The identified burdens and needs of relatives should be considered by health care professionals to enhance the delirium experience for them, thus improving patient care by involving relatives with a better understanding.

Patients' and Relatives' Experiences of Delirium in the Intensive Care Unit-A Qualitative Study

(1) Introduction: Delirium is a cognitive disorder that affects up to 80% of ICU patients and has many negative consequences. The occurrence of delirium in an ICU patient also negatively affects the relatives caring for these patients. The aim of this study was to explore patients' and their families' experiences of delirium during their ICU stay. (2) Method: The study used a qualitative design based on phenomenology as a research method. A semi-structured interview method was used to achieve the aim. The responses of patients and their families were recorded and transcribed, and the data were coded and analyzed. (3) Results: Eight interviews were conducted with past ICU patients who developed delirium during hospitalization and their family members. The mean age of the participants was 71 years. Of the eight patients, 2 (25%) were female and 6 (75%) were male. The relationships of the 8 carers with the patients were wife (in 4 cases), daughter (in 2 cases), and son (in 2 cases). The average length of time a patient stayed in the ICU was 24 days. The following themes were extracted from the interviews: education, feelings before the delirium, pain, thirst, the day after, talking to the family/patient, and return home. (4) Conclusions: Post-delirium patients and their families feel that more emphasis should be placed on information about delirium. Most patients feel embarrassed and ashamed about events during a delirium episode. Patients fear the reaction of their families when delirium occurs. Patients' families are not concerned about their relatives returning home and believe that the home environment will allow them to forget the delirium events more quickly during hospitalization.

Longitudinal validation of an electronic health record delirium prediction model applied at admission in COVID-19 patients

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.

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.

Terminal Delirium in Hospice: The Experiences and Perspectives of Caregivers Providing Care to Terminally Ill Patients in Home Settings

OBJECTIVES

Little is known about the experiences of caregivers who provide care to persons with terminal delirium (TD) in home settings. This scarcity of information is suggestive that further research is needed about care for hospice patients with delirium in the home and community.

AIM

To elicit views, feelings, and end-of-life care experiences of primary caregivers assisting dying persons with TD in hospice at home.

DESIGN

Qualitative, exploratory, cross-sectional study design was chosen. In-depth semistructured interviews explored caregiver experiences in caring for persons with TD. Qualitative thematic framework analysis was used.

PARTICIPANTS

Fifteen bereaved adult primary caregivers who received services from a hospice care program affiliated with a large nonprofit health system in the US Midwest.

RESULTS

Caregiver experiences were broad and reflected 4 major themes: symptomology, coping, effective and noneffective interventions, and support. The most distressing factors for caregivers were behaviors and symptomology of TD. They did not know what to say, how to respond, and how best to behave with someone who had delirium. Many caregivers had the impression that medication does not lessen delirium symptoms and that nonpharmacologic interventions are effective and beneficial only when they were important and meaningful to patients before delirium onset.

CONCLUSIONS

This study added new knowledge from direct and personal perspectives of caregivers providing end-of-life care to patients at home. Understanding developed about provision of care to someone with TD in home hospice. Improved comprehension of caregiver experiences can help professional hospice and palliative care staff better prepare caregivers for when patients have TD.

Stratified delirium risk using prescription medication data in a state-wide cohort

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.

Family caregiver's experience of caring for an older adult with delirium: A systematic review

AIM

To enhance understanding of how family caregivers perceive the experience of caring for an older adult with delirium across care settings and to identify the challenges in recognising and managing delirium to inform future research and best practices.

METHOD

A systematic literature review was conducted in five databases per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria. Primary or secondary peer-reviewed articles published between 1987 and October 2018 describing the experiences of family caregivers caring for older adults with delirium or delirium superimposed on dementia were included in the review. Mixed Method Appraisal Tool (MMAT) was used to evaluate the methodological quality. A thematic synthesis of results was conducted to extract relevant data as per the aims of the study.

RESULTS

Eighteen articles met the eligibility criteria, which were reviewed and analysed in regard to purpose, sample, research design, variables and results. Seven themes emerged in the process. The current challenges and gaps in our knowledge of this phenomenon have also been highlighted, which should be helpful to inform best practices, and finally, an agenda for future research is proposed.

CONCLUSION

Family caregivers are an important partner in the detection and management of delirium. The impact of caring for an older adult with delirium on the family caregivers should not be overlooked. This paper highlights the dearth of research on family caregiver's experience of caring for older adults with delirium and even less in the context of delirium superimposed on dementia. More research is required to further understand the family caregiver's experience and their challenges in order to support them in their caregiving role and to determine their needs and preferences of being involved in the plan of care.

IMPLICATIONS FOR PRACTICE

These findings suggest that family caregivers are a valuable resource in the recognition and management of delirium and should be included as care partners in the health care team, while also catering to their health and well-being in the process.

What do geriatric patients experience during an episode of delirium in acute care hospitals? : A qualitative study

BACKGROUND

Predispositions and triggers for delirium, such as noxious agents are known and behavior can be monitored; however, there is little to no information available regarding the experience of patients during delirium episodes. Not much is known about a person's world of experiences, which therefore mostly remains as a sort of black box.

OBJECTIVE

This study was motivated by the following question: "What do (Austrian) geriatric patients experience during an episode of delirium in an acute care hospital?" The main objective of this article is to present little snippets from the experiences and to allow geriatric patients to speak for themselves.

PATIENTS AND METHODS

From 2013 to 2016 interviews were carried out within the framework of a qualitative investigation. For data collection narrative interviews according to Fritz Schütze were employed and 10 interviews were conducted in a hospital setting with German-speaking Austrian patients aged between 75 and 90 years (mean age 80.2 years; 7 female and 3 male). The individual interviews lasted between 60 and 120 min. Primary data in the form of individual interpretation and interpretation groups from interview transcripts were marked and coded according to Mayring.

RESULTS

All patients who participated in the interviews subjectively recognized delirium as a negative experience. The data analysis led to three main categories with subcategories: changes in sensory perception, extraordinarily strong emotions and memories. It is important to differentiate between two very different types of memories: firstly, personal fate or life changes and secondly, those regarding experiences of war.

CONCLUSION

Scandinavian and Anglo-American literature describe different categories, such as a change in reality, strong emotions and dramatic episodes in the experience of delirium, which can be transferred to Austria. Others consider the biography of each individual patient in context with the sociocultural history of Austria, especially following developments after 1940.

Delirium Screening and Management in Inpatient Rehabilitation Facilities

Delirium is an acute and fluctuating disturbance in cognition attention and awareness that is often a reflection of abnormal physiological condition of an individual. Delirium is highly prevalent among an older population and is associated with high mortality, poor medical and functional outcomes, and high healthcare cost. Delirium often has iatrogenic triggers, and it has been recognized as a quality indicator of healthcare organizations. Despite its high prevalence and significance, more than 50% of the delirium cases are underrecognized by healthcare professionals and remained untreated. Most patients in inpatient rehabilitation facilities are older adults with multiple risk factors for delirium including operation, intensive care stay, multiple co-morbidities, and impaired mobility. Early detection, intervention, and primary prevention of delirium will allow patients to avoid additional morbidities and reach their maximum functional potential during their rehabilitation stay. After the systematic implementation of delirium screening in our inpatient rehabilitation facility, we found that 10.3% of patients were screened positive for delirium at admission. This review discusses the systematic implementation of screening and intervention for delirium as well as the epidemiology of delirium to increase the awareness and guide clinical practice for clinicians in inpatient rehabilitation facilities.

Do health care professionals worry about delirium? Relatives' experience of delirium in the intensive care unit: A qualitative interview study

OBJECTIVES

In intensive care units, there is a high incidence of delirium, which relates to the risk of complications. Engagement of relatives is an acknowledged part of handling delirium, but knowledge of relatives' perspectives is lacking.

AIM

To explore relatives' experiences of delirium in the critically ill patient admitted to an intensive care unit.

RESEARCH DESIGN

A qualitative design with a phenomenological approach. Semi-structured interviews with eleven relatives of critically ill patients who had delirium during admission to the intensive care unit.

SETTING

An intensive care unit in Denmark.

FINDINGS

Three categories emerged: 'Delirium is not the main concern', 'Communication with health-care professionals is crucial', and 'Delirium impacts on relatives'. Relatives had a lack of knowledge of delirium. Symptoms of delirium were thought of as a natural consequence of critical illness and seemed to be a secondary problem. Health-care professionals did not talk about delirium and information was requested. Delirium and the manifestation of it was experienced in different ways and brought different ways of coping.

CONCLUSION

Findings give a new insight into relatives' experience of delirium in the intensive care unit. Relatives need more information to better understand delirium. Future research must investigate the potential in helping relatives to cope with delirium, to the benefit of both patient and relatives.

Delirium management by palliative medicine specialists: a survey from the association for palliative medicine of Great Britain and Ireland

OBJECTIVES

Delirium is common in palliative care settings. Management includes detection, treatment of cause(s), non-pharmacological interventions and family support; strategies which are supported with varying levels of evidence. Emerging evidence suggests that antipsychotic use should be minimised in managing mild to moderate severity delirium, but the integration of this evidence into clinical practice is unknown.

METHODS

A 21-question online anonymous survey was emailed to Association for Palliative Medicine members in current clinical practice (n=859), asking about delirium assessment, management and research priorities.

RESULTS

Response rate was 39%: 70% of respondents were palliative medicine consultants. Delirium guidelines were used by some: 42% used local guidelines but 38% used none. On inpatient admission, 59% never use a delirium screening tool. Respondents would use non-pharmacological interventions to manage delirium, either alone (39%) or with an antipsychotic (58%). Most respondents (91%) would prescribe an antipsychotic and 6% a benzodiazepine, for distressing hallucinations unresponsive to non-pharmacological measures. Inpatient (57%) and community teams (60%) do not formally support family carers. Research priorities were delirium prevention, management and prediction of reversibility.

CONCLUSION

This survey of UK and Irish Palliative Medicine specialists shows that delirium screening at inpatient admission is suboptimal. Most specialists continue to use antipsychotics in combination with non-pharmacological interventions to manage delirium. More support for family carers should be routinely provided by clinical teams. Further rigorously designed clinical trials are urgently needed in view of management variability, emerging evidence and perceived priorities for research.

Family Caregivers' Experiences of Within-Hospital Handoffs for Older Adults in Acute Care

Family caregivers' experiences during within-hospital handoffs between acute care units are not well understood. Qualitative description methodology was employed to describe family caregivers' experiences during their loved ones' handoffs. Semistructured interviews were conducted with 10 caregivers of hospitalized older adults. Three themes emerged: Lack of care coordination, Muddling through handoffs alone, and Wariness toward the care delivery system. Findings can help clinicians shape their interactions with caregivers to maximize their involvement in post-hospital care.

What effect does delirium have on family and nurses of older adult patients?

OBJECTIVES

This study aims to analyse the level of distress caused by delirium in patients' family and their nurses, and to identify factors associated with psychological distress in families of older adult inpatients in Intermediate Care Units/IMCUs regarding their global experience during hospitalization.

METHOD

A prospective pilot study was carried out with families and nurses of older adult patients (≥65 y.o.) consecutively recruited from two IMCUs in Intensive Care Medicine Service in a University Hospital. Patients with Glasgow Coma Scale ≤11, brain injury, blindness/deafness and inability to communicate were excluded. Delirium was daily assessed with Confusion Assessment Method/CAM. The distress level regarding this episode in family and nurses was measured with Delirium Experience Questionnaire/DEQ. Family psychological distress of all recruited patients was assessed with Kessler Psychological Distress Scale/K10.

RESULTS

This study included 42 inpatients (mean age/MA = 78 y.o., 50% women), 32 families (68.8% sons/daughters, MA = 50.6 y.o., 81.3% women) and 12 nurses caring for delirium patients (MA = 33 y.o., all women). A total of 12 (28.6%) patients had delirium. Distress related to this episode were higher for families than for nurses (M = 3 vs. M = 2), but differences did not reach statistical significance (Z = -1.535, p = 0.125). The hierarchical regression model explained 44.3% of variability in family psychological distress. Higher levels of psychological distress were associated with living with the patient (p = 0.029), presence of previous cognitive decline (p = 0.048) and development of delirium (p = 0.010).

CONCLUSION

These preliminary results show that family psychological distress is higher, when older adult patients developed delirium during hospitalization. Particular attention to these family carers should be given in future development of psychological support and psychoeducational interventions.

Understanding cognition in older patients with cancer

Cancer and neurocognitive disorders, such as dementia and delirium, are common and serious diseases in the elderly that are accompanied by high degree of morbidity and mortality. Furthermore, evidence supports the under-diagnosis of both dementia and delirium in older adults. Complex questions exist regarding the interaction of dementia and delirium with cancer, beginning with guidelines on how best measure disease severity, the optimal screening test for either disorder, the appropriate level of intervention in the setting of abnormal findings, and strategies aimed at preventing the development or progression of either process. Ethical concerns emerge in the research setting, pertaining to the detection of cognitive dysfunction in participants, validity of consent, disclosure of abnormal results if screening is pursued, and recommended level of intervention by investigators. Furthermore, understanding the ways in which comorbid cognitive dysfunction and cancer impact both cancer and non-cancer-related outcomes is essential in guiding treatment decisions. In the following article, we will discuss what is presently known of the interactions of pre-existing cognitive impairment and delirium with cancer. We will also discuss identified deficits in our knowledge base, and propose ways in which innovative research may address these gaps.

Protocol for the Electroencephalography Guidance of Anesthesia to Alleviate Geriatric Syndromes (ENGAGES) study: a pragmatic, randomised clinical trial

INTRODUCTION

Postoperative delirium, arbitrarily defined as occurring within 5 days of surgery, affects up to 50% of patients older than 60 after a major operation. This geriatric syndrome is associated with longer intensive care unit and hospital stay, readmission, persistent cognitive deterioration and mortality. No effective preventive methods have been identified, but preliminary evidence suggests that EEG monitoring during general anaesthesia, by facilitating reduced anaesthetic exposure and EEG suppression, might decrease incident postoperative delirium. This study hypothesises that EEG-guidance of anaesthetic administration prevents postoperative delirium and downstream sequelae, including falls and decreased quality of life.

METHODS AND ANALYSIS

This is a 1232 patient, block-randomised, double-blinded, comparative effectiveness trial. Patients older than 60, undergoing volatile agent-based general anaesthesia for major surgery, are eligible. Patients are randomised to 1 of 2 anaesthetic approaches. One group receives general anaesthesia with clinicians blinded to EEG monitoring. The other group receives EEG-guidance of anaesthetic agent administration. The outcomes of postoperative delirium (≤5 days), falls at 1 and 12 months and health-related quality of life at 1 and 12 months will be compared between groups. Postoperative delirium is assessed with the confusion assessment method, falls with ProFaNE consensus questions and quality of life with the Veteran's RAND 12-item Health Survey. The intention-to-treat principle will be followed for all analyses. Differences between groups will be presented with 95% CIs and will be considered statistically significant at a two-sided p<0.05.

ETHICS AND DISSEMINATION

Electroencephalography Guidance of Anesthesia to Alleviate Geriatric Syndromes (ENGAGES) is approved by the ethics board at Washington University. Recruitment began in January 2015.

Mum's absence(s): conceptual insights into absence as loss during a loved one's delirium

AIMS AND OBJECTIVES

To examine qualitative research findings about family experiences of absence or loss during older person delirium, and provide a critical discussion of the similarities and differences in these experiences with conceptual understandings of absence and loss.

BACKGROUND

Families who care for older people with chronic illnesses experience many losses. However, the nondeath loss experiences of family during an older loved one's delirium, an acute condition accompanied by marked changes in demeanour, have received little consideration.

DESIGN

Discursive position paper.

METHODS

The findings from two qualitative research studies about family experiences during an older loved one's delirium are discussed in relation to the concepts of absence and nondeath loss.

RESULTS

The uncharacteristic behaviours and cognitive changes that accompany delirium may estrange family who, despite the older person's corporeal presence, sense the profound absence or loss of their loved one. Although the notion of absence, a nondeath loss, is similar to the experiences of family of people with chronic conditions, there are differences that distinguish these encounters. The similarities and differences between absence during delirium and the concepts of psychological absence, nonfinite loss and psychosocial death are discussed. Psychosocial death, reversibility/irreversibility and partial marked change, are suggested as conceptual descriptions for the absence families experience during an older loved one's delirium.

CONCLUSIONS

The sense of absence or loss that family may experience during their older loved one's delirium needs to be recognised, understood and addressed by healthcare staff. Understanding or appreciating conceptualisations of absence, as a nondeath loss, may enhance understandings of family member needs during delirium and enable better support strategies.

RELEVANCE TO CLINICAL PRACTICE

Conceptualisations of absence enhance understandings of family distress and needs during their older loved one's delirium. The potential for family members to experience their loved one's absence during delirium, a nondeath loss, needs to be considered by healthcare staff. Family experiences of absence during delirium need to be recognised by healthcare staff, acknowledged as a potential source of distress, and considered when involving family in the older person's care. Nurses are ideally placed to respond compassionately and provide appropriate family member re-assurance, support and information during delirium. Information should include possible impacts on family and coping strategies.

The experiences of caregivers of patients with delirium, and their role in its management in palliative care settings: an integrative literature review

OBJECTIVES

To explore the experiences of caregivers of terminally ill patients with delirium, to determine the potential role of caregivers in the management of delirium at the end of life, to identify the support required to improve caregiver experience and to help the caregiver support the patient.

METHODS

Four electronic databases were searched-PsychInfo, Medline, Cinahl and Scopus from January 2000 to July 2015 using the terms 'delirium', 'terminal restlessness' or 'agitated restlessness' combined with 'carer' or 'caregiver' or 'family' or 'families'. Thirty-three papers met the inclusion criteria and remained in the final review.

RESULTS

Papers focused on (i) caregiver experience-distress, deteriorating relationships, balancing the need to relieve suffering with desire to communicate and helplessness versus control; (ii) the caregiver role-detection and prevention of delirium, symptom monitoring and acting as a patient advocate; and (iii) caregiver support-information needs, advice on how to respond to the patient, interventions to improve caregiver outcomes and interventions delivered by caregivers to improve patient outcomes.

CONCLUSION

High levels of distress are experienced by caregivers of patients with delirium. Distress is heightened because of the potential irreversibility of delirium in palliative care settings and uncertainty around whether the caregiver-patient relationship can be re-established before death. Caregivers can contribute to the management of patient delirium. Additional intervention studies with informational, emotional and behavioural components are required to improve support for caregivers and to help the caregiver support the patient. Reducing caregiver distress should be a goal of any future intervention.© 2016 The Authors. Psycho-Oncology Published by John Wiley & Sons Ltd.

Educating Family Caregivers for Older Adults About Delirium: A Systematic Review

BACKGROUND

Delirium in older adults is considered a medical emergency; it contributes to a cascade of functional decline and to increased mortality. Early recognition of delirium symptoms is critical to prevent these negative consequences. Family caregivers who are educated about delirium could partner with nurses and other healthcare professionals in early recognition of delirium symptoms. Before implementing such partnership models, it is important to examine the effectiveness of educating family caregivers about delirium.

AIMS

To examine whether providing education on delirium to family caregivers improved their knowledge, emotional state, or response in reducing the incidence of delirium in older adults.

METHODS

For this systematic review, we conducted literature searches in CINAHL, Cochrane Library, Medline, PsycINFO, Web of Science, Social Sciences in ProQuest, Dissertations and Theses, and the Virginia Henderson Global Nursing eRepository for studies published in the English language between January 2000 and June 2015. Criteria for inclusion were: (a) primary focus on educating family caregivers for older adults about delirium; (b) use of experimental, quasi-experimental, or comparative design; (c) measured family caregiver outcomes of delirium knowledge, emotional state, or response in reducing delirium incidence in older adults; and (d) published in the English language. Articles were appraised using Melnyk's rapid critical appraisal guides.

RESULTS

Seven studies met the review criteria. Four studies found that family caregivers' delirium knowledge increased; two noted that delirium incidence in older adults declined; and one study reported less distress following receipt of education.

LINKING EVIDENCE TO ACTION

Providing family caregivers with information about delirium can be beneficial for both family caregivers and older adults. However, rigorous evaluation of education programs for family caregivers about delirium is needed.

Delirium superimposed on dementia: A quantitative and qualitative evaluation of informal caregivers and health care staff experience

OBJECTIVE

Delirium superimposed on dementia is common and potentially distressing for patients, caregivers, and health care staff. We quantitatively and qualitatively assessed the experience of informal caregiver and staff (staff nurses, nurse aides, physical therapists) caring for patients with delirium superimposed on dementia.

METHODS

Caregivers' and staff experience was evaluated three days after delirium superimposed on dementia resolution (T0) with a standardized questionnaire (quantitative interview) and open-ended questions (qualitative interview); caregivers were also evaluated at 1-month follow-up (T1).

RESULTS

A total of 74 subjects were included; 33 caregivers and 41 health care staff (8 staff nurses, 20 physical therapists, 13 staff nurse aides/health care assistants). Overall, at both T0 and T1, the distress level was moderate among caregivers and mild among health care staff. Caregivers reported, at both T0 and T1, higher distress related to deficits of sustained attention and orientation, hypokinesia/psychomotor retardation, incoherence and delusions. The distress of health care staff related to each specific item of the Delirium-O-Meter was relatively low except for the physical therapists who reported higher level of distress on deficits of sustained/shifting attention and orientation, apathy, hypokinesia/psychomotor retardation, incoherence, delusion, hallucinations, and anxiety/fear. The qualitative evaluation identified important categories of caregivers' and staff feelings related to the delirium experience.

CONCLUSIONS

This study provides information on the implication of the experience of delirium on caregivers and staff. The distress related to delirium superimposed on dementia underlines the importance of providing continuous training, support and experience for both the caregivers and health care staff to improve the care of patients with delirium superimposed on dementia.
