Barriers and facilitators to nursing delirium screening in older emergency patients: a qualitative study using the theoretical domains framework

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).

Mid-life plasma proteins associated with late-life prefrailty and frailty: a proteomic analysis

Physical frailty is a syndrome that typically manifests in later life, although the pathogenic process causing physical frailty likely begins decades earlier. To date, few studies have examined the biological signatures in mid-life associated with physical frailty later in life. Among 4,189 middle-aged participants (57.8 ± 5.0 years, 55.8% women) from the Atherosclerosis Risk in Community (ARIC) study, we evaluated the associations of 4,955 plasma proteins (log 2-transformed and standardized) measured using the SomaScan platform with their frailty status approximately 20 years later. Using multinomial logistic regression models adjusting for demographics, health behaviors, kidney function, total cholesterol, and comorbidities, 12 and 221 proteins were associated with prefrailty and frailty in later life, respectively (FDR p < 0.05). Top frailty-associated proteins included neurocan core protein (NCAN, OR = 0.66), fatty acid-binding protein heart (FABP3, OR = 1.62) and adipocyte (FABP4, OR = 1.65), as well proteins involved in the contactin-1 (CNTN1), toll-like receptor 5 (TLR5), and neurogenic locus notch homolog protein 1 (NOTCH1) signaling pathway relevant to skeletal muscle regeneration, myelination, and inflammation. Pathway analyses suggest midlife dysregulation of inflammation, metabolism, extracellular matrix, angiogenesis, and lysosomal autophagy among those at risk for late-life frailty. After further adjusting for midlife body mass index (BMI) - an established frailty risk factor - only CNTN1 (OR = 0.75) remained significantly associated with frailty. Post-hoc analyses demonstrated that the top 41 midlife frailty-associated proteins mediate 32% of the association between mid-life BMI and late-life frailty. Our findings provide new insights into frailty etiology earlier in the life course, enhancing the potential for prevention.

Stroke and frailty index: a two-sample Mendelian randomisation study

INTRODUCTION

Previous observational studies have found an increased risk of frailty in patients with stroke. However, evidence of a causal relationship between stroke and frailty is scarce. The aim of this study was to investigate the potential causal relationship between stroke and frailty index (FI).

METHODS

Pooled data on stroke and debility were obtained from genome-wide association studies (GWAS).The MEGASTROKE Consortium provided data on stroke (N = 40,585), ischemic stroke (IS,N = 34,217), large-vessel atherosclerotic stroke (LAS,N = 4373), and cardioembolic stroke (CES,N = 7 193).Summary statistics for the FI were obtained from the most recent GWAS meta-analysis of UK BioBank participants and Swedish TwinGene participants of European ancestry (N = 175,226).Two-sample Mendelian randomization (MR) analyses were performed by inverse variance weighting (IVW), weighted median, MR-Egger regression, Simple mode, and Weighted mode, and heterogeneity and horizontal multiplicity of results were assessed using Cochran's Q test and MR-Egger regression intercept term test.

RESULTS

The results of the current MR study showed a significant correlation between stroke gene prediction and FI (odds ratio 1.104, 95% confidence interval 1.064 - 1.144, P < 0.001). In terms of stroke subtypes, IS (odds ratio 1.081, 95% confidence interval 1.044 - 1.120, P < 0.001) and LAS (odds ratio 1.037, 95% confidence interval 1.012 - 1.062, P = 0.005). There was no causal relationship between gene-predicted CES and FI. Horizontal multidimensionality was not found in the intercept test for MR Egger regression (P > 0.05), nor in the heterogeneity test (P > 0.05).

CONCLUSIONS

This study provides evidence for a causal relationship between stroke and FI and offers new insights into the genetic study of FI.

Developing a set of emergency department performance measures to evaluate delirium care quality for older adults: a modified e-Delphi study

BACKGROUND

Older adults are at high risk of developing delirium in the emergency department (ED); however, it is under-recognized in routine clinical care. Lack of detection and treatment is associated with poor outcomes, such as mortality. Performance measures (PMs) are needed to identify variations in quality care to help guide improvement strategies. The purpose of this study is to gain consensus on a set of quality statements and PMs that can be used to evaluate delirium care quality for older ED patients.

METHODS

A 3-round modified e-Delphi study was conducted with ED clinical experts. In each round, participants rated quality statements according to the concepts of importance and actionability, then their associated PMs according to the concept of necessity (1-9 Likert scales), with the ability to comment on each. Consensus and stability were evaluated using a priori criteria using descriptive statistics. Qualitative data was examined to identify themes within and across quality statements and PMs, which went through a participant validation exercise in the final round.

RESULTS

Twenty-two experts participated, 95.5% were from west or central Canada. From 10 quality statements and 24 PMs, consensus was achieved for six quality statements and 22 PMs. Qualitative data supported justification for including three quality statements and one PM that achieved consensus slightly below a priori criteria. Three overarching themes emerged from the qualitative data related to quality statement actionability. Nine quality statements, nine structure PMs, and 14 process PMs are included in the final set, addressing four areas of delirium care: screening, diagnosis, risk reduction and management.

CONCLUSION

Results provide a set of quality statements and PMs that are important, actionable, and necessary to a diverse group of clinical experts. To our knowledge, this is the first known study to develop a de novo set of guideline-based quality statements and PMs to evaluate the quality of delirium care older adults receive in the ED setting.

Implementation of geriatric screening in the emergency department using the Consolidated Framework for Implementation Research

OBJECTIVE

Implementation of evidence-based care processes (EBP) into the emergency department (ED) is challenging and there are only a few studies of real-world use of theory-based implementation frameworks. We report final implementation results and sustainability of an EBP geriatric screening program in the ED using the Consolidated Framework for Implementation Research (CFIR).

METHODS

The EBP involved nurses screening older patients for delirium (Delirium Triage Screen), fall risk (4-Stage Balance Test), and vulnerability (Identification of Seniors at Risk score) with subsequent appropriate referrals to physicians, therapy specialists, or social workers. The proportions of screened adults ≥65 years old were tracked monthly. Outcomes are reported January 2021-December 2022. Barriers encountered were classified according to CFIR. Implementation strategies were classified according to the CFIR-Expert Recommendations for Implementing Change (ERIC).

RESULTS

Implementation strategies increased geriatric screening from 5% to 68%. This did not meet our prespecified goal of 80%. Change was sustained through several COVID-19 waves. Inner setting barriers included culture and implementation climate. Initially, the ED was treated as a single inner setting, but we found different cultures and uptake between ED units, including night versus day shifts. Characteristics of individuals barriers included high levels of staff turnover in both clinical and administrative roles and very low self-efficacy from stress and staff turnover. Initial attempts with individualized audit and feedback were not successful in improving self-efficacy and may have caused moral injury. Adjusting feedback to a team/unit level approach with unitwide stretch goals worked better. Identifying early adopters and conducting on-shift education increased uptake. Lessons learned regarding ED culture, implementation in interconnected health systems, and rapid cycle process improvement are reported.

CONCLUSIONS

The pandemic exacerbated barriers to implementation in the ED. Cognizance of a large ED as a sum of smaller units and using the CFIR model resulted in improvements.

A qualitative evidence synthesis (QES) exploring the barriers and facilitators to screening in emergency departments using the theoretical domains framework

BACKGROUND

Validated screening tools can be utilised to detect early disease processes and risk factors for disease and adverse outcomes. Consequently, identifying individuals in need of early intervention and targeted assessment can be achieved through the implementation of screening in the ED. Successful implementation can be impacted by a lack of resources and ineffective integration of screening into the clinical workflow. Tailored implementation processes and staff training, which are contextually specific to the ED setting, are facilitators to effective implementation. This review will assist in the identification of barriers and facilitators to screening in the ED using a QES to underpin implementation processes. Healthcare workers engage in screening in the ED routinely. Consequently, this review focused on synthesizing the experience of healthcare workers (HCWs) who are involved in this process. This synthesis is informed by a QES protocol published by the lead author in 2021 (Barry et al., HRB Open Res 3:50, 2021).

METHODOLOGY

A comprehensive literature search, inclusive of grey literature sources, was undertaken. Initially, an a priori framework of themes was formed to facilitate the interpretation and organisation of search results. A context specific conceptual model was then formulated using "Best fit" framework synthesis which further assisted in the interpretation of data that was extracted from relevant studies. Dual blind screening of search results was undertaken using RAYYAN as a platform. Thirty studies were identified that met the inclusion criteria. Dual appraisal of full text articles was undertaken using CASP, GRADE CERQual assessed confidence of findings and data extraction was performed by two reviewers collaboratively.

FINDINGS

This is the first known synthesis of qualitative research on HCW's experiences of screening in the ED. Predominantly, the findings illustrate that staff experience screening in the ED as a complex challenging process. The barriers and facilitators identified can be broadly categorised under preconditions to screen, motivations to screen and knowledge and skills to screen. Competing interests in the ED, environmental stressors such as overcrowding and an organisational culture that resists screening were clear barriers. Adequate resources and tailored education to underpin the screening process were clear facilitators.

A critical appraisal and recommendation synthesis of delirium clinical practice guidelines relevant to the care of older adults in the emergency department: An umbrella review

RATIONALE

Older adults are at high risk of developing delirium in the emergency department (ED); however, it is often missed or undertreated. Improving ED delirium care is challenging in part due to a lack of standards to guide best practice. Clinical practice guidelines (CPGs) translate evidence into recommendations to improve practice.

AIM

To critically appraise and synthesize CPG recommendations for delirium care relevant to older ED patients.

METHODS

We conducted an umbrella review to retrieve relevant CPGs. Quality of the CPGs and their recommendations were critically appraised using the Appraisal of Guidelines, Research, and Evaluation (AGREE)-II; and Appraisal of Guidelines Research and Evaluation-Recommendations Excellence (AGREE-REX) instruments. A threshold of 70% or greater in the AGREE-II Rigour of Development domain was used to define high-quality CPGs. Delirium recommendations from CPGs meeting this threshold were included in the synthesis and narrative analysis.

RESULTS

AGREE-II Rigour of Development scores ranged from 37% to 83%, with 5 of 10 CPGs meeting the predefined threshold. AGREE-REX overall calculated scores ranged from 44% to 80%. Recommendations were grouped into screening, diagnosis, risk reduction, and management. Although none of the included CPGs were ED-specific, many recommendations incorporated evidence from this setting. There was agreement that screening for nonmodifiable risk factors is important to define high-risk populations, and those at risk should be screened for delirium. The '4A's Test' was the recommended tool to use in the ED specifically. Multicomponent strategies were recommended for delirium risk reduction, and for its management if it occurs. The only area of disagreement was for the short-term use of antipsychotic medication in urgent situations.

CONCLUSION

This is the first known review of delirium CPGs including a critical appraisal and synthesis of recommendations. Researchers and policymakers can use this synthesis to inform future improvement efforts and research in the ED.

Barriers to delirium screening and management during hospital admission: a qualitative analysis of inpatient nursing perspectives

BACKGROUND

Delirium in hospitalized patients is a major public health issue, yet delirium is often unrecognized and missed during inpatient admission. The objective of this study was to identify barriers to delirium screening, identification, and management from a nursing perspective on inpatient, acute care units.

METHODS

This was a pre-implementation, diagnostic evaluation study to determine current practice patterns and potential barriers to optimizing delirium care at a major university hospital. A qualitative approach was used, which included focus groups of inpatient nurses working on major medical and surgical acute care units. Focus groups were conducted until signs of thematic saturation were present, and data were analyzed via inductive thematic analysis, without predetermined theories or structures. A consensus approach was utilized for transcript coding, and final themes were generated after multiple reviews of initial themes against transcript datasets.

RESULTS

Focus group sessions (n = 3) were held with 18 nurses across two major inpatient units. Nurses reported several barriers to successful delirium screening and management. Specific challenges included difficulty with using delirium screening tools, an organizational culture not conducive to delirium prevention, and competing clinical priorities. Proposed solutions were also discussed, including decision-support systems with automated pager alerts and associated delirium order sets, which may help improve delirium care coordination and standardization.

CONCLUSION

At a major university hospital, nurses affirm the difficulty experienced with delirium screening and identification, particularly due to screening tool challenges, cultural barriers, and clinical workload. These impediments may serve as targets for a future implementation trial to improve delirium screening and management.

A survey on the availability of geriatric-friendly protocols, equipment and physical environment across emergency departments in Flanders, Belgium

BACKGROUND

The acquisition of geriatric-friendly resources is an important part of adapting emergency department (ED) care to the needs of vulnerable older patients. The aim of this study was to explore the availability of geriatric-friendly protocols, equipment and physical environment criteria in EDs and to identify related improvement opportunities.

METHODS

The head nurse of 63 EDs in Flanders and Brussels Capital Region was invited to complete a survey in collaboration with the chief physician of the ED. The questionnaire was inspired by the American College of Emergency Physicians Geriatric ED Accreditation Program and explored the availability, relevance and feasibility of geriatric-friendly protocols, equipment and physical environment. Descriptive analyses were performed. A region-wide improvement opportunity was defined as a resource that was never to occasionally (0-50%) available on Flemish EDs and was scored (rather or very) relevant by at least 75% of respondents.

RESULTS

A total of 32 questionnaires were analysed. The response rate was 50.8%. All surveyed resources were available in at least one ED. Eighteen out of 52 resources (34.6%) were available in more than half of EDs. Ten region-wide improvement opportunities were identified. These comprised seven protocols and three physical environment characteristics: 1) a geriatric approach initiated from physical triage, 2) elder abuse, 3) discharge to residential facility, 4) frequent geriatric pathologies, 5) access to geriatric specific follow-up clinics, 6) medication reconciliation, 7) minimising 'nihil per os' designation, 8) a large-face, analogue clock in each patient room, 9) raised toilet seats and 10) non-slip floors.

CONCLUSIONS

Currently available resources supporting optimal ED care for older patients in Flanders are very heterogeneous. Researchers, clinicians and policy makers need to define which geriatric-friendly protocols, equipment and physical environment criteria should become region-wide minimum operational standards. Findings of this study are relevant to facilitate the development process of this endeavour.

A critical appraisal of delirium clinical practice guidelines relevant to the care of older adults in the emergency department with a synthesis of recommendations: an umbrella review protocol

BACKGROUND

Up to 35% of older adults present to the emergency department (ED) with delirium or develop the condition during their ED stay. Delirium associated with an ED visit is independently linked to poorer outcomes such as loss of independence, increased length of hospital stay, and mortality. Improving the quality of delirium care for older ED patients is hindered by a lack of knowledge and standards to guide best practice. High-quality clinical practice guidelines (CPGs) have the power to translate the complexity of scientific evidence into recommendations to improve and standardize practice. This study will identify and synthesize recommendations from high-quality delirium CPGs relevant to the care of older ED patients.

METHODS

We will conduct a multi-phase umbrella review to retrieve relevant CPGs. Quality of the CPGs and their recommendations will be critically appraised using the Appraisal of Guidelines, Research, and Evaluation (AGREE)-II; and Appraisal of Guidelines Research and Evaluation - Recommendations Excellence (AGREE-REX) instruments, respectively. We will also synthesize and conduct a narrative analysis of high-quality CPG recommendations.

DISCUSSION

This review will be the first known evidence synthesis of delirium CPGs including a critical appraisal and synthesis of recommendations. Recommendations will be categorized according to target population and setting as a means to define the bredth of knowledge in this area. Future research will use consensus building methods to identify which are most relevant to older ED patients.

Understanding why delirium is often missed in older emergency department patients: a qualitative descriptive study

OBJECTIVES

Unrecognized delirium is associated with significant adverse outcomes. Despite decades of effort and educational initiatives, validated screening tools have not improved delirium recognition in the emergency department (ED). There remains a fundamental knowledge gap of why it is consistently missed. The objective of this study was to explore the perceptions of ED physicians and nurses regarding factors contributing to missed delirium in older ED patients.

METHODS

We conducted a qualitative descriptive study at two academic tertiary care EDs in Toronto, Canada. Emergency physicians and nurses were interviewed by a trained qualitative researcher using a semi-structured interview guide. We coded transcripts with an iteratively developed codebook. Interviews were conducted until thematic saturation occurred. Thematic data analysis occurred in conjunction with data collection to continuously monitor emerging themes and areas for further exploration.

RESULTS

We interviewed 26 ED physicians and nurses. We identified key themes at four levels: clinical practice, provider attitudes, systematic processes, and education. The four themes include: (1) there are varied approaches to delirium recognition and infrequent use of screening tools; (2) delirium assessment is perceived as overly time consuming and of lower priority than other symptoms and syndromes; (3) it is unclear whose responsibility it is to recognize delirium; and (4) there is a need for a deeper or "functional" understanding of delirium that includes its consequences.

CONCLUSIONS

Our findings demonstrate a need for ED leadership to identify clear team roles for delirium recognition, standardize use of delirium screening tools, and prioritize delirium as a symptom of an acute medical emergency.
