Delirium: A Survey of Healthcare Professionals’ Knowledge, Beliefs, and Practices

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.

REPORTING METHOD

This systematic review was reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (Page et al., 2021).

A qualitative study of geriatric specialist nurses' experiences to navigate delirium in the elderly

BACKGROUND

The experiences and perceptions of geriatric specialist nurses are pivotal to understanding the complexities of managing delirium and to developing effective nursing interventions. This qualitative study aims to explore these experiences and perceptions to inform the enhancement of clinical geriatric nursing and care practices.

METHODS

Utilizing a qualitative exploratory design, this research engaged a convenience sample of geriatric specialist nurses at a tertiary hospital in Shanghai, China through focus groups and semi-structured interviews. Data were rigorously analyzed using Colaizzi's phenomenological method, which facilitated the identification of themes that emerged from the narratives of the geriatric specialist nurses.

RESULTS

The thematic analysis yielded three major themes that encapsulate the nurses' experiences and perceptions. Theme 1: Understanding of Delirium, highlighted the nurses' awareness of the condition's significance, yet it was often deprioritized due to the pressing demands of managing more acute and immediately life-threatening conditions. Theme 2: Barriers in Application, brought to light the multifaceted challenges faced by nurses, including language barriers, the frequency and consistency of delirium assessments, the social determinants of health, and the nurses' own competencies in assessment. Theme 3: Evolution of Nursing Approaches, detailed the adaptive strategies employed by nurses, such as managing nursing adverse events, improving communication with patients' families, and adopting a proactive stance towards long-term patient outcomes.

CONCLUSIONS

The findings suggest that while geriatric specialist nurses recognize the importance of delirium assessment, there are several barriers to effective application. The study underscores the imperative for the advancement of more refined delirium assessment and care protocols, tailored to address the unique requirements of geriatric nursing care.

Application, knowledge and training needs regarding comprehensive geriatric assessment among geriatric practitioners in healthcare institutions: a cross-sectional study

BACKGROUND

This study aimed to investigate the actual application, knowledge, and training needs of comprehensive geriatric assessment (CGA) among geriatric practitioners in China.

METHODS

A total of 225 geriatric practitioners attending the geriatric medicine or geriatric nursing training were recruited for this cross-sectional study. The questionnaire included demographics, healthcare institution characteristics, the actual application, knowledge, training needs, and barriers to CGA and geriatric syndromes (GS).

RESULTS

Physicians and nurses were 57.3% and 42.7%, respectively. 71.1% were female, with a median age was 35 years. Almost two-thirds (140/225) of geriatric practitioners reported exposure to CGA in their clinical practice. The top five CGA evaluation items currently used were malnutrition risk (49.8%), fall risk (49.8%), activity of daily living (48.0%), pain (44.4%), and cognitive function (42.7%). Median knowledge scores for the management procedures of GS ranged from 2 to 6. Physicians identified medical insurance payment issues (29.5%) and a lack of systematic specialist knowledge and technology (21.7%) as the two biggest barriers to practicing geriatrics. Nurses cited a lack of systematic specialist knowledge and technology (52.1%) as the primary barrier. In addition, physicians and nurses exhibited significant differences in their knowledge of CGA-specific evaluation items and management procedures for GS (all P < 0.05). However, there were no significant differences in their training needs, except for polypharmacy.

CONCLUSIONS

The rate of CGA application at the individual level, as well as the overall knowledge among geriatric practitioners, was not adequate. Geriatric education and continuous training should be tailored to address the specific roles of physicians and nurses, as well as the practical knowledge reserves, barriers, and training needs they face.

Knowledge, attitude and practice regarding hypoactive delirium among ICU nurses: A nationwide cross-sectional study

AIMS AND OBJECTIVES

This study aimed to assess the knowledge, attitude and practice (KAP) of intensive care unit (ICU) nurses in patients with hypoactive delirium in China.

BACKGROUND

The presentation of hypoactive delirium is not obvious and tends to be ignored. However, it has a high incidence and can cause critical impairment. Although nurses are the primary caregivers of patients, the evidence of the current status of KAP of hypoactive delirium among ICU nurses is insufficient in China.

DESIGN

The study participants were 2835 ICU nurses from 201 hospitals in 69 cities from 31 provinces in China.

METHODS

The current status of KAP of hypoactive delirium among ICU nurses was determined using a self-reported structured questionnaire, including 52 questions covering general personal information; three dimensions of KAP; and relevant issues. Descriptive analyses of the sample distribution were reported as percentages and medians. The factors were detected using univariate and multivariate analyses. To guide the reporting of the research, a STROBE checklist of cross-sectional studies was used.

RESULTS

Of the 3101 returned questionnaires, 2835 were analyzed. Approximately 64. 94 % and 53. 30 % of them were identified with a positive attitude and appropriate practice, respectively, whereas only 1. 48 % showed a good level of knowledge. The regression analysis showed that age, years of working in the ICU, educational background, professional title, caring for patients with delirium, attending training on hypoactive delirium and hospital grading were significantly associated with their KAP status(P＜005).

CONCLUSIONS

Hypoactive delirium is an ignored entity by nursing professionals, with no definite nursing procedure. This study shows that receiving relevant training is a factor affecting KAP status, indicating that training should be strengthened. Additionally, appropriate screening and nursing procedures should be developed to standardize the behavior of ICU nurses and improve the quality of care.

RELEVANCE TO CLINICAL PRACTICE

ICU nurses have poor knowledge of hypoactive delirium and related training should be strengthened, especially for middle-aged nurses. Screening and nursing procedures should be set up, which is critical to promote nursing practice.

Knowledge, attitude, and practice regarding postoperative delirium among cardiac surgery nurses: A cross-sectional multi-centre study

AIMS AND OBJECTIVES

To examine knowledge, attitude, and practice regarding postoperative delirium and the relationships among cardiac surgery nurses in China.

BACKGROUND

Postoperative delirium is a prevalent and devastating complication following cardiac surgery. Nurses play a part in multi-disciplinary collaboration for preventing and managing postoperative delirium, of whom knowledge, attitude, and practice are essential.

DESIGN

A cross-sectional multi-centre study.

METHODS

Nurses from cardiac surgery wards and intensive care units of five tertiary hospitals in Wuhan, Hubei Province, China were enrolled. Data were gathered online using a self-administered questionnaire. Student's t-test, or analysis of variance, or non-parametric tests were performed to compare differences across groups. Bootstrapping mediation analysis was conducted to examine the relationship between knowledge, attitude, and practice. The STROBE checklist was used for the reporting of this study.

RESULTS

Of 429 nurses, a moderate level of knowledge and high levels of attitude and practice regarding postoperative delirium were revealed. Nurses with higher education, higher academic title, 5-10 years of practice in nursing and cardiac surgery nursing exhibited increased knowledge. With advanced age, practice in a specialised hospital, and training experience, nurses reported a better degree of practice. Attitude played a full mediating effect in the relationship between knowledge and practice, accounting for 81.82% of the total effects.

CONCLUSIONS

Knowledge, attitude, and practice regarding postoperative delirium are promising among Chinese cardiac surgery nurses, with knowledge of screening tools and perioperative nonpharmacological interventions and practice of screening in need of enhancement. Attitudes act as an intermediary between knowledge and practice regarding postoperative delirium.

RELEVANCE TO CLINICAL PRACTICE

Innovative and stratified in-service education is warranted to address knowledge enhancement. Meanwhile, organisations are suggested to make efforts to foster nurses' positive attitudes, particularly in creating a favourable culture and developing institutional protocols for postoperative delirium management to improve practice.

NO PATIENT OR PUBLIC CONTRIBUTION

This study is focused on cardiac surgery nurses' knowledge, attitude, and practice regarding postoperative delirium, and the research questions and design are from clinical nursing practice, literature review, and expert panel review, in which the patient or public is temporarily not involved.

Managing delirium in acute inpatient units: A cross-sectional study of nursing teams' knowledge and perceived limitations

AIM

The aim of the study was to describe nursing teams' theoretical knowledge of delirium and their perceptions of the way in which it is handled in acute inpatient units.

DESIGN

This is a descriptive cross-sectional study using a questionnaire comprising ten questions on knowledge and seven on perception.

METHODS

The sample consisted of 216 professionals working at a hospital complex in Madrid, Spain. Descriptive and non-parametric bivariate analyses were performed for a p < .05.

RESULTS

Fifty-three point two per cent of staff possessed sufficient theoretical knowledge, and this figure rose significantly among professionals with more years of experience. Areas for improvement in theoretical knowledge included the use of therapeutic immobilization, screening scale, subtypes of delirium and precipitating factors. Sixty-eight point five per cent of staff perceived their knowledge as fair, 50% agreed that delirium was underdiagnosed and 48.1% agreed that preventive measures were only occasionally taken. Perceived barriers included lack of training, work overload, ineffective coordination and lack of standardized protocols.

Patient Safety: Cognitive Assessment at Intensive Care Unit Discharge

Topic

Assessing functional cognition is a critical need for intensive care unit survivors transitioning to another level of care.

Clinical Relevance

Up to 62% of patients discharged from an intensive care unit have significant cognitive impairment that is not associated with severity of illness, number of comorbidities, or length of hospital stay. For more than 20 years, researchers have published an array of potentially effective interventions, including case management, patient and informal caregiver education, and home health care services.

Purpose

To describe the impact of and potential interventions for cognitive decline at intensive care unit discharge and discharge readiness on 30-day readmission rates.

Content Covered

Assessing the patient’s functional cognition assessment and advocating for appropriate resources are needed to improve patient and clinical outcomes.

Knowledge, attitude, and practice toward delirium and subtype assessment among Chinese clinical nurses and determinant factors: A multicentre cross-section study

Background

Delirium, a confused transient state of consciousness, can be divided into hyperactive, hypoactive, mixed, and no motor subtypes, according to different clinical manifestations. Several studies have investigated delirium subtypes in the knowledge dimension, but few studies have investigated delirium subtype in the attitude and practice dimensions. The barriers, knowledge sources, and practice details regarding subtype assessment are unclear.

Objectives

This study had three objectives. First, we planned to investigate the KAP status regarding delirium and subtypes for nurses. Second, we wanted to identify factors affecting clinical nurses' KAP scores. Third, this study expected to explore more details regarding delirium and subtypes assessment, including assessment barriers, assessment instruments, and knowledge sources.

Methods

This multicentre cross-section study was conducted in 10 tertiary hospitals in three provinces, China, from January to April 2022. We investigated 477 nurses from six departments with a high prevalence. The self-developed KAP questionnaire regarding delirium and subtypes assessment had four parts: knowledge, attitude, practice, and source. Its reliability and validity were verified effectively by 2-round Delphi expert consultation.

Results

A total of 477 nurses from the general intensive care unit (ICU), specialty ICU, orthopedics, thoracic surgery, operating room, and geriatrics were 28.3, 22.4, 22.2, 10.5, and 5.2%, respectively. The total KAP score regarding delirium and subtypes assessment was 60.01 ± 6.98, and the scoring rate was 73.18%. The scoring rate for knowledge, attitude, and practice was 58.55, 83.94, and 51.70%, respectively. More than half (54.1%) were unaware of the delirium subtypes assessment instruments. A total of 451 (94.6%) participants recognized the importance of nursing work for delirium prevention. A total of 250 (52.4%) nurses occasionally or sometimes assessed delirium subtypes, and 143 (30.0%) never assessed for delirium subtypes. We found that age, department, technical title, familiarity with delirium, familiarity with delirium subtypes, delirium training, and subtype training affected the total KAP scores. ICU nurses achieved the highest scores.

Conclusion

Chinese nurses' KAP status regarding delirium and subtypes assessment were barely acceptable, and the attitude score was positive, but knowledge and practice needed improvement. Meanwhile, the department was one of the significant KAP factors, and ICU nurses did better in delirium and subtype assessment in knowledge and practice dimension than other departments. Systematic and scientific training processes including subtype content and assessment tools are required. Experience still drives nurses' assessments of delirium and subtype. Adding the delirium assessment into routine tasks should be considered.

Quality Improvement in Delirium Health Literacy in Older Adult Patients and Their Caregivers Attending a Geriatric Clinic

Background

Delirium is a common medical condition that is highly prevalent in older adults who are at increased risk for its development with any illness, post-surgery or during hospitalization. The purpose of our study was to evaluate the health literacy of older adult patients and their caregivers about delirium, offer a brief educational intervention, and reevaluate their knowledge post intervention.

Materials and Methods

We conducted a quality improvement project, focused on delirium health literacy in older adult patients ≥60 years and their caregivers. Delirium knowledge of participants was evaluated in a pre-education survey after which they were given a delirium education booklet to read. A post-education delirium survey was conducted within 2-3 weeks of the educational intervention. Chi-square test was used to analyze the knowledge base of older adults.

Results

The study population consisted of a total of 70 older adults who participated in pre-education (n=35) and post-education (n=35) surveys. Older adult patients and their caregivers had significant knowledge gaps about the potential causes or etiologies, risk factors, symptomatology, and prevention of delirium in the pre-education survey. After the educational intervention, in the post-education survey, there were overall improvements in knowledge base of older adults in differentiating delirium with dementia (43% vs 94%, p<0.01) recognizing signs and symptoms (77% vs 94%, p<0.05), complications (76% vs 100%, p<0.01) and identifying the etiological factors associated with delirium.

Conclusion

The quality improvement project demonstrated that older adults and caregivers have significant knowledge deficits about the common condition of delirium. This study also demonstrated that older adults were able to improve their health literacy regarding delirium after the intervention. Appropriate education on delirium for patients and caregivers might help in earlier identification, prevention, and better overall management of delirium.

Recipe for primary prevention of delirium in hospitalized older patients

Delirium is an acute fluctuating syndrome characterized by a change in consciousness, perception, orientation, cognition, sleep-wake rhythm, psychomotor skills, and the mood and feelings of a patient. Delirium and delirium prevention remain a challenge for healthcare professionals, especially nurses who form the basis of patient care. It also causes distress for patients, their caregivers and healthcare professionals. However, delirium is preventable in 30-40% of cases. The aim of this article is to summarize the delirium risk models, delirium screening tools, and (non-pharmacological) delirium prevention strategies. A literature search of review articles supplemented by original articles published in PubMed, Cinahl, and Cochrane between 1 January 2000 and 31 December 2020 was carried out. Among the older patients, delirium is a common condition with major consequences in terms of mortality and morbidity, but prevention is possible. Despite the fact that delirium risk models, delirium screening scales and non-pharmacological prevention are available for the development of a hospital delirium prevention programme, such a programme is still not commonly used on a daily basis.

Physicians' Beliefs and Attitudes Toward Hypoactive Delirium in The Last Days of Life

CONTEXT

The perspective toward hypoactive delirium in the last days of life could be different among physicians.

OBJECTIVES

To clarify the attitudes, beliefs, and opinions of palliative care physicians and liaison psychiatrists toward hypoactive delirium in the last days of life and to explore the association among these factors.

METHODS

A nationwide cross-sectional questionnaire survey was conducted among 1667 physicians who were either certified palliative care specialists or liaison psychiatrists. Physicians' agreement with the appropriateness of pharmacological management (e.g., antipsychotics) (one item), their beliefs (11 items), and their opinions (four items) were measured.

RESULTS

787 (47%) physicians responded. 481 (62%) agreed to use of medications for hypoactive delirium in the last days of life, whereas 296 (38.1%) disagreed. More than 95% agreed with "hypoactive delirium at the end of life can be considered as a part of natural dying process." Multivariate analysis identified two belief subscales of "hypoactive delirium at the end of life is a natural dying process" and "antipsychotics are futile and harmful in managing hypoactive delirium" had a significant negative correlation with the use of medications. On the other hand, one belief subscale of "hypoactive delirium can be distressing even if patients' consciousness is impaired" had significant positive correlations with the use of medications.

CONCLUSION

Pharmacological management of hypoactive delirium in the last days of life differs depending on physicians' beliefs. Future research is needed to clarify the efficacy and safety of pharmacological management of hypoactive delirium.

Nurse-Driven Assessment, Prevention, and Management of Delirium on an Acute Inpatient Neurology Unit

BACKGROUND

Delirium commonly affects hospitalized patients and is associated with increased hospital length of stay, discharge to skilled care, cost, morbidity, and mortality.

LOCAL PROBLEM

At our organization, there was no formal delirium assessment performed by the nursing staff outside of the intensive care unit.

METHODS

Assessment of nurses' knowledge about delirium, a nurse-driven delirium screening protocol, and patient education were implemented on an adult inpatient neurology unit. Knowledge change, protocol implementation, and patient-level outcomes were assessed.

INTERVENTIONS

Staff nurse delirium education and a nurse-driven delirium screening protocol were implemented.

RESULTS

No change in nursing knowledge occurred pre/postintervention. Falls, falls with injury, and restraint and sitter usage decreased. Changes in length of stay varied over the intervention period. The trend to discharge to home increased, while the trend to discharge to skilled nursing care decreased.

CONCLUSIONS

Formal delirium screening protocols may add organizational value by positively impacting patient outcomes.

Effect of an evidence-based poster on the knowledge of delirium and its prevention in student nurses: A quasi-experimental study

BACKGROUND

A major barrier to nurses adopting evidence-based practice (EBP) has been the limited awareness of evidence underpinning clinical practice, often due to poor access and understanding of the literature base. To address this, we piloted the development of educational posters summarizing the evidence base around clinical practices to see if they help nurses better understand the rationale behind their care. Our first poster focused on the evidence supporting the management of delirium in older persons, specifically delirium identification and its prevention.

OBJECTIVE

To examine the effect of an evidence-based poster education on the delirium knowledge of student nurses.

DESIGN

A prospective two-armed quasi-experimental study.

METHODS

188 student nurses were recruited in December 2017. Participants were alternated to receive either an evidence-based poster education session or a reflective education session as a control. Both groups were assessed on their general knowledge on delirium, knowledge on delirium detection and knowledge on delirium prevention. This was conducted both before exposure to either the intervention or control, and one week after exposure. Unpaired t-tests with 95% confidence intervals (CI) were applied to compare the mean change in pre-test and post-test delirium knowledge. We used the Transparent Reporting of Evaluations with Nonrandomized Designs (TREND) checklist to report our methods and findings.

RESULTS

Students in the poster education group reported greater improvements in mean scores of delirium identification (Mean increase =1.0, p = 0.007, 95% CI: 0.3-1.6), delirium prevention (Mean increase =1.6, p < 0.001, 9% CI: 1.0-2.2) and overall delirium knowledge (Mean increase = 2.7, p < 0.001, 95% CI: 1.5-3.8) than students in the control.

CONCLUSION

Summarised research evidence within a poster format can increase student nurses' access to the evidence base. This has shown to increase their knowledge to guide their clinical practice.

IMPACT STATEMENT

Exposure to poster summaries of research evidence underpinning delirium care increases student nurses' clinical knowledge of delirium identification and prevention.

A delirium prevalence audit and a pre and post evaluation of an interprofessional education intervention to increase staff knowledge about delirium in older adults

Background

Delirium is more prevalent in older people and estimated to occur in up to 50% of the hospital population. Delirium comprises a spectrum of behaviours, including cognitive and attention deficits, and fluctuating levels of consciousness, often associated with an underlying physiological disturbance. Delirium has been increasingly associated with adverse outcomes. Although often preventable or can at least be mitigated, delirium may not be a standard part of assessment and thus may not be recognized in the early stages when it is most likely to be treated successfully. The aim of this study was to evaluate the level of knowledge of delirium amongst clinicians caring for patients at high risk of developing delirium and to determine whether education can improve clinical assessment of delirium.

Methods

Two hundred and forty-six case notes were audited before and 149 were reviewed after the education intervention and implementation of a delirium screening tool. Clinicians at the hospital were invited to complete a questionnaire on knowledge of delirium. The questionnaire was based on a validated tool which contained 39 questions about delirium. The questionnaire also contained 28 questions on delirium knowledge. Additional questions were included to gather demographic information specific to the hospital. Descriptive statistics, chi square and independent t-tests were conducted to test for differences in knowledge between the pre and post periods. The Squire Checklist Reporting Guidelines for Quality Improvement Studies informed the preparation of the manuscript.

Results

The audit demonstrated that the use of a cognitive assessment tool overall increased from 8.5% in pre education to 43% in the post education period. One hundred and fifty-nine staff completed the questionnaire in total, 118 the pre and 41 post. The knowledge subscale score was high pre and post education and no statistically significant difference was observed. The greatest increase in knowledge was related to knowledge of the risk factors subscale. The increase in knowledge (6.8%) was statistically significant.

Conclusion

An interprofessional approach to delirium education was effective in not only increasing awareness of the factors associated with this syndrome but also increased the use of a delirium assessment tool.

Increased Emergency Department Hallway Length of Stay is Associated with Development of Delirium

Introduction

Our study aimed to determine 1) the association between time spent in the emergency department (ED) hallway and the development of delirium and 2) the hospital location of delirium development.

Methods

This single-center, retrospective chart review included patients 18+ years old admitted to the hospital after presenting, without baseline cognitive impairment, to the ED in 2018. We identified the Delirium group by the following: key words describing delirium; orders for psychotropics, special observation, and restraints; or documented positive Confusion Assessment Method (CAM) screen. The Control group included patients not meeting delirium criteria. We used a multivariable logistic regression model, while adjusting for confounders, to assess the odds of delirium development associated with percentage of ED LOS spent in the hallway.

Results

A total of 25,156 patients met inclusion criteria with 1920 (7.6%) meeting delirium criteria. Delirium group vs. Control group patients spent a greater percentage of time in the ED hallway (median 50.5% vs 10.8%, P<0.001); had longer ED LOS (median 11.94 vs 8.12 hours, P<0.001); had more ED room transfers (median 5 vs 4, P<0.001); and had longer hospital LOS (median 5.0 vs 4.6 days, P<0.001). Patients more frequently developed delirium in the ED (77.5%) than on inpatient units (22.5%). The relative odds of a patient developing delirium increased by 3.31 times for each percent increase in ED hallway time (95% confidence interval, 2.85, 3.83).

Conclusion

Patients with delirium had more ED hallway exposure, longer ED LOS, and more ED room transfers. Understanding delirium in the ED has substantial implications for improving patient safety.

Effectiveness of a Delirium Prevention Initiative on an Inpatient Neuroscience Unit

ABSTRACT

BACKGROUND: Delirium frequently develops in hospitalized patients and results in increased mortality, longer length of stay, and need for transitional care. Neurological patients are at an increased risk for developing delirium. There is a paucity of research on effective prevention strategies for this population. PURPOSE: The objectives of this project were to improve nurses' knowledge and confidence in delirium prevention, design a delirium volunteer program, and establish ongoing monitoring for continued improvement. METHODS: This study is a quality improvement project using a pretest-posttest design to examine the benefits of refocusing care from delirium management to delirium prevention. The sample included 304 patients pre and 332 post intervention. The interventions included delirium education for nurses and the recruitment of trained volunteers to implement nonpharmacological, multicomponent delirium prevention interventions. RESULTS: Forty-eight nurses completed delirium education, and 11 volunteers were recruited and trained. There was a significant increase in nursing knowledge (z = 3.967, P < .0005) and confidence (z = 3.989, P < .0005). Volunteers visited 54 patients and implemented 99 interventions post implementation. CONCLUSION: This pre-post improvement project provides beginning evidence that nursing education increased nurses' knowledge and confidence in preventing and treating delirium. Trained volunteers supported using nonpharmacological delirium prevention interventions, but ongoing evaluation is needed to determine the impact of volunteers on delirium rates.

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.

Consolidated framework for advancing implementation science for the implementation process and adherence assessment of a non-pharmacological delirium prevention program

OBJECTIVE

To evaluate the contribution of applying the theoretical framework of implementation science for adherence to non-pharmacological interventions to prevent delirium.

METHODS

A quasi-experimental prospective design was conducted from March 2017 to October 2018 in a teaching hospital. Participants included 149 healthcare staff and 72 elderly inpatients. A non-pharmacological delirium prevention program was designed, applied and evaluated in accordance with the consolidated framework for advancing implementation research (CFIR). The primary outcome was the global adherence rate to 12 predefined indicators, comparing measurements at baseline (O1), after training (O2) and at a 6-month follow-up (O3) assessed by an external reviewer. Staff knowledge and beliefs about delirium were assessed using a validated tool, and delirium incidence was evaluated using the confusion assessment method.

RESULTS

Overall adherence increased from 58.2% (O1) to 77.9% (O2) and 75.6% (O3) (O2 vs. O1: p < 0.001 and O3 vs. O1: p < 0.001). Staff perceptions regarding implementation of non-pharmacological interventions increased from 74.8% to 81.9% (p = 0.004). Delirium incidence was non-significantly reduced from 20% (O1) to 16% (O3) (p = 0.99).

CONCLUSIONS

Implementation of a delirium prevention program using a CFIR model was useful in improving adherence to activities included in this program, as well as improving the knowledge and beliefs regarding delirium by healthcare workers. The impact of this implementation strategy on the incidence of delirium should be evaluated in a larger scale multicenter trial.

The geriatric certificate program: collaborative partnerships for building capacity for a competent workforce

Many practicing health care providers find themselves ill-prepared to meet the complex care needs of older adults. The Geriatric Certificate Program (GCP) represents a collaborative partnership leveraging existing educational courses, with new courses developed to fill existing education gaps, aimed at improving quality of care for older adults. This paper describes the GCP and examines its impact on knowledge, skills, clinical practice, as well as confidence, comfort, and competence in providing geriatric care. Upon program completion, all graduates (N = 146; 100%) completed an online evaluation survey. The majority of graduates reported (5-point scale: 1 = much less now; 5 = much more now) being more confident (88%), comfortable (83%), and competent (89%) to provide optimal geriatric care than prior to the program. The GCP provides a significant opportunity for health care providers to build their capacity for the care of older adults. Key lessons learned in implementing the GCP and suggestions for further development are discussed.

Perceptions of current occupational therapy practice with older adults experiencing delirium

OBJECTIVES

To describe the perceptions of Australian occupational therapists of their role, knowledge and skills in enabling older adults with delirium to participate in meaningful occupations.

METHODS

This is a mixed-methods cross-sectional study. Participants (n = 91) completed an online survey, with quantitative data analysed descriptively and qualitative data subjected to content analysis.

RESULTS

Occupational therapists had good general delirium knowledge, but less understanding of specific risk factors. Participants asserted the importance of occupational therapy assessment and treatment for older people experiencing delirium and generally felt confident or somewhat confident in their skills. While all participants provided collaborative care with multidisciplinary team members, only a minority thought colleagues had a satisfactory knowledge of the occupational therapy role with delirium.

CONCLUSION

Currently, the role of occupational therapy with older people experiencing delirium remains emerging rather than established, and there are many opportunities for further research and development in this practice area.

The 4 'A's test for detecting delirium in acute medical patients: a diagnostic accuracy study

BACKGROUND

Delirium is a common and serious neuropsychiatric syndrome, usually triggered by illness or drugs. It remains underdetected. One reason for this is a lack of brief, pragmatic assessment tools. The 4 'A's test (Arousal, Attention, Abbreviated Mental Test - 4, Acute change) (4AT) is a screening tool designed for routine use. This project evaluated its usability, diagnostic accuracy and cost.

METHODS

Phase 1 - the usability of the 4AT in routine practice was measured with two surveys and two qualitative studies of health-care professionals, and a review of current clinical use of the 4AT as well as its presence in guidelines and reports. Phase 2 - the 4AT's diagnostic accuracy was assessed in newly admitted acute medical patients aged ≥ 70 years. Its performance was compared with that of the Confusion Assessment Method (CAM; a longer screening tool). The performance of individual 4AT test items was related to cognitive status, length of stay, new institutionalisation, mortality at 12 weeks and outcomes. The method used was a prospective, double-blind diagnostic test accuracy study in emergency departments or in acute general medical wards in three UK sites. Each patient underwent a reference standard delirium assessment and was also randomised to receive an assessment with either the 4AT (n = 421) or the CAM (n = 420). A health economics analysis was also conducted.

RESULTS

Phase 1 found evidence that delirium awareness is increasing, but also that there is a need for education on delirium in general and on the 4AT in particular. Most users reported that the 4AT was useful, and it was in widespread use both in the UK and beyond. No changes to the 4AT were considered necessary. Phase 2 involved 785 individuals who had data for analysis; their mean age was 81.4 (standard deviation 6.4) years, 45% were male, 99% were white and 9% had a known dementia diagnosis. The 4AT (n = 392) had an area under the receiver operating characteristic curve of 0.90. A positive 4AT score (> 3) had a specificity of 95% [95% confidence interval (CI) 92% to 97%] and a sensitivity of 76% (95% CI 61% to 87%) for reference standard delirium. The CAM (n = 382) had a specificity of 100% (95% CI 98% to 100%) and a sensitivity of 40% (95% CI 26% to 57%) in the subset of participants whom it was possible to assess using this. Patients with positive 4AT scores had longer lengths of stay (median 5 days, interquartile range 2.0-14.0 days) than did those with negative 4AT scores (median 2 days, interquartile range 1.0-6.0 days), and they had a higher 12-week mortality rate (16.1% and 9.2%, respectively). The estimated 12-week costs of an initial inpatient stay for patients with delirium were more than double the costs of an inpatient stay for patients without delirium (e.g. in Scotland, £7559, 95% CI £7362 to £7755, vs. £4215, 95% CI £4175 to £4254). The estimated cost of false-positive cases was £4653, of false-negative cases was £8956, and of a missed diagnosis was £2067.

LIMITATIONS

Patients were aged ≥ 70 years and were assessed soon after they were admitted, limiting generalisability. The treatment of patients in accordance with reference standard diagnosis limited the ability to assess comparative cost-effectiveness.

CONCLUSIONS

These findings support the use of the 4AT as a rapid delirium assessment instrument. The 4AT has acceptable diagnostic accuracy for acute older patients aged > 70 years.

FUTURE WORK

Further research should address the real-world implementation of delirium assessment. The 4AT should be tested in other populations.

Postoperative delirium: the findings from a multidisciplinary survey

BACKGROUND

Delirium is a common postoperative neurocognitive complication in the older population and can lead to significant morbidity and mortality, as well as cognitive and functional impairment. Hypoactive delirium is characterised by drowsiness and inactivity, and expert opinions suggest that it is more likely to be missed and can lead to more complications. Current guidelines and literature evidence both support the use of non-pharmacological management of delirium.

METHODS

To investigate the recognition of hyperactive and hypoactive delirium by the surgical multidisciplinary team, and to investigate staff understanding regarding the management and prognosis of postoperative delirium. We conducted a single-centre, multidisciplinary survey on the diagnosis, management and complication of postoperative delirium.

RESULTS

We found that hypoactive delirium is significantly less likely to be identified. In contrast, acute psychosis is likely to be misdiagnosed as delirium. Only a small proportion of the respondents had knowledge of the supportive management options for delirium; and the medical complications and higher mortality risk associated with postoperative delirium.

DISCUSSION

The finding of the survey demonstrates a need for delirium education. Surveys such as this may be conducted in other centres to identify areas of focus on staff delirium education.

Evaluation of a co-produced delirium awareness programme for undergraduate nursing students in Northern Ireland: a pre-test/post-test study

BACKGROUND

Delirium is recognised internationally as a common disorder that causes acute deterioration in a person's cognitive abilities. Healthcare professionals play a key role in the early identification and management of delirium and effective education can support timely recognition and treatment. There is currently a lack of research exploring the delirium education provided to undergraduate nursing students. The aim of this study was to evaluate the effectiveness of a co-produced delirium awareness programme on undergraduate nursing students in Northern Ireland.

METHODS

The intervention was a 2-h delirium workshop, delivered in April 2019, to a convenience sample of year one undergraduate nursing students (n = 206) completing a BSc Honours Nursing degree programme in a Northern Ireland University. The workshop focused on four core elements: defining delirium, reflecting on practice, recognition of delirium and management of delirium. Participants completed a 35-item true-false Delirium Knowledge Questionnaire (DKQ) at baseline and post intervention using Socrative, a cloud-based student response system. In addition, students also completed a short questionnaire at baseline and post-workshop, designed by the authors, to ascertain perceived confidence about caring for people with delirium. Data were analysed using paired t-tests and descriptive statistics.

RESULTS

In the DKQ, Scores were normally distributed around the mean at baseline (71.89%) and post intervention (81.89%). Students improved across all three core areas in the post-test questionnaire, demonstrating improvements in knowledge about symptoms of delirium (7.32% increase), causes and risk factors of delirium (17.91% increase) and management of delirium (5.72% increase). In relation to perceived confidence, students reported a 60.20% increase in confidence related to recognition of delirium, a 49.51% increase in relation to delirium management and a 45.04% increase their ability to communicate about delirium. Both questionnaires were statistically significant (P < 0.01).

CONCLUSIONS

A 2-h workshop on delirium improved first year student nurse knowledge about delirium. Nursing students expressed that this approach to delirium education enabled collective thinking about how knowledge could be transferred into individual practises. Students also stated that learning incorporating the voice of the person who has experienced delirium, was an effective and powerful way to deliver education.

An Advanced Practice Provider Initiative for Delirium Management in the ICU

Delirium is the most common neuropsychiatric challenge in cancer patients, particularly in the critically ill population. Without a screening method and constant vigilance by providers, delirium is often misdiagnosed. The purpose of our pilot study was to determine if an educational program targeting critical care medicine advanced practice providers (APPs) and fellows in an oncologic intensive care unit would increase APP knowledge of delirium and their level of comfort with delirium screening and management. Thirty-one APPs and fellows participated in the program. Scores on knowledge-based delirium assessments increased significantly after the intervention and at the 3-month follow-up (p < .0001 and p < .0225, respectively). Providers’ comfort with delirium screening and management also improved after the intervention (p = .0020 and p < .0001, respectively) and decreased slightly at the 3-month follow-up (p = .1764 and p = .9840, respectively). A brief and focused APP-led educational initiative successfully improved knowledge of delirium and comfort with screening and management.

Multimodal Education Program to Improve Nurses' Knowledge and Confidence on Delirium Recognition in a Surgical-Trauma Intermediate-Care Setting

Background

High incidence of delirium in hospitalized patients has been reported in the United States and is significantly associated with increased morbidity and mortality. The lack of knowledge and confidence in performing delirium assessment (KCDA) has led to significant underrecognition of delirium by nurses regardless of evidence-based education intervention.

Objective

The purpose of this study was to determine the effectiveness of a multimodal educational program (MEP) to enhance nurses' KCDA.

Methods

A MEP including an online didactic with a video-simulation and 1:1 bedside coaching with delirium screening (DS) was conducted in the surgical intermediate-care unit of an academic medical center. A quasi-experimental pre- and post-test design was used.

Results

Of 23 nurses, the majority were <41 years old (73.9%) and had at least a bachelor of science in nursing degree (78.3%) with <6 years of experience (60.9%). The overall KCDA scores and the performance of DS improved significantly after the MEP (p < .001). A positive correlation was noted between the changes of the KCDA scores (p = .009).

Conclusions

The MEP demonstrated improvement in nurses' KCDA. The MEP should focus on an individualized learning approach with a targeted patient population, using current delirium screening tools.

Implications for Nursing

Educational programs are recommended in either an orientation or continuing education program on nursing units. This is also recommended for use in other academic centers that encompass similar clinical settings and could possibly be considered for use in other disease processes.
