Abstract
A comprehensive view of factors associated with AD/ADRD will significantly aid in studies to develop new treatments for AD/ADRD and identify high-risk populations and patients for prevention efforts. In our study, we summarized the risk factors for AD/ADRD by reviewing existing meta-analyses and review articles on risk and preventive factors for AD/ADRD. In total, we extracted 477 risk factors in 10 categories from 537 studies. We constructed an interactive knowledge map to disseminate our study results. Most of the risk factors are accessible from structured Electronic Health Records (EHRs), and clinical narratives show promise as information sources. However, evaluating genomic risk factors using RWD remains a challenge, as genetic testing for AD/ADRD is still not a common practice and is poorly documented in both structured and unstructured EHRs. Considering the constantly evolving research on AD/ADRD risk factors, literature mining via NLP methods offers a solution to automatically update our knowledge map.

[PMID: 38091654 DOI: 10.1016/j.ijnurstu.2023.104645] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2023] [Revised: 10/09/2023] [Accepted: 11/09/2023] [Indexed: 01/23/2024]
Abstract
BACKGROUND Delirium is a common yet challenging condition in older hospitalized patients, associated with various adverse outcomes. Environmental factors, such as room changes, may contribute to the development or severity of delirium. Most previous research has focused on preventing and reducing this condition by addressing risk factors and facilitating reorientation during hospital stay. OBJECTIVE We aimed to systematically develop a complex intervention to prevent delirium in older hospitalized patients by optimizing discharge and transfer processes and involving caregivers during and after these procedures. The intervention combines stakeholder and expert opinions, evidence, and theory. This article provides guidance and inspiration to research groups in developing complex interventions according to the recommendations in the Medical Research Council framework for complex interventions. DESIGN AND METHODS A stepwise multi-method study was conducted. The preparation phase included analysis of the context and current practice via focus groups. Based on these results, an expert workshop was organized, followed by a Delphi survey. Finally, the intervention was modeled and a program theory was developed, including a logic model. RESULTS A complex intervention was developed in an iterative process, involving healthcare professionals, delirium experts, researchers, as well as caregiver and patient representatives. The key intervention component is an 8-point-program, which provides caregivers with recommendations for preventing delirium during the transition phase and in the post-discharge period. Information materials (flyers, handbook, videos, posters, defined "Dos and Don'ts", discharge checklist), training for healthcare professionals, and status analyses are used as implementation strategies. In addition, roles were established for gatekeepers to act as leaders, and champions to serve as knowledge multipliers and trainers for the multi-professional team in the hospitals. CONCLUSIONS This study serves as an example of how to develop a complex intervention. In an additional step, the intervention and implementation strategies will be investigated for feasibility and acceptability in a pilot study with an accompanying process evaluation. TWEETABLE ABSTRACT Delirium prevention can benefit from optimizing discharge and transfer processes and involving caregivers of older patients in these procedures.

Identification of risk factors for the onset of delirium associated with COVID-19 by mining nursing records. PLoS One 2024; 19:e0296760.

Abstract
COVID-19 has a range of complications, from no symptoms to severe pneumonia. It can also affect multiple organs including the nervous system. COVID-19 affects the brain, leading to neurological symptoms such as delirium. Delirium, a sudden change in consciousness, can increase the risk of death and prolong the hospital stay. However, research on delirium prediction in patients with COVID-19 is insufficient. This study aimed to identify new risk factors that could predict the onset of delirium in patients with COVID-19 using machine learning (ML) applied to nursing records. This retrospective cohort study used natural language processing and ML to develop a model for classifying the nursing records of patients with delirium. We extracted the features of each word from the model and grouped similar words. To evaluate the usefulness of word groups in predicting the occurrence of delirium in patients with COVID-19, we analyzed the temporal changes in the frequency of occurrence of these word groups before and after the onset of delirium. Moreover, the sensitivity, specificity, and odds ratios were calculated. We identified (1) elimination-related behaviors and conditions and (2) abnormal patient behavior and conditions as risk factors for delirium. Group 1 had the highest sensitivity (0.603), whereas group 2 had the highest specificity and odds ratio (0.938 and 6.903, respectively). These results suggest that these parameters may be useful in predicting delirium in these patients. The risk factors for COVID-19-associated delirium identified in this study were more specific but less sensitive than the ICDSC (Intensive Care Delirium Screening Checklist) and CAM-ICU (Confusion Assessment Method for the Intensive Care Unit). However, they are superior to the ICDSC and CAM-ICU because they can predict delirium without medical staff and at no cost.

[PMID: 37826889 DOI: 10.1016/j.ijnurstu.2023.104584] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2023] [Revised: 07/30/2023] [Accepted: 08/02/2023] [Indexed: 10/14/2023]
Abstract
BACKGROUND As advanced age is a major risk factor for confusion status, delirium has become prevalent in the older population, contributing to longer hospital stays, cognitive impairment, and higher risks of complications and mortality. Compared with pharmacological methods, non-pharmacological interventions are preferred and are recommended by the National Institute for Health and Care Excellence for the prevention of delirium. Numerous systematic reviews and meta-analyses have been carried out to investigate the effects of non-pharmacological interventions. However, the outcomes were diverse and the quality varied widely, making it challenging to draw firm conclusions from the evidence. OBJECTIVE To summarize the contents and evaluate the effects of non-pharmacological interventions to prevent and treat delirium among older people. DESIGN Overview of systematic reviews. METHODS A comprehensive literature search was conducted in Medline, Cochrane Library, EMBASE, CINAHL, PsycINFO, JBI EBP Database, China's SinoMed, CNKI, and Wangfang databases from inception to 2nd December 2022. Two reviewers performed the study selection, quality appraisal, and data extraction independently. The AMSTAR 2 tool was used to appraise the methodological quality of eligible reviews. The results were presented in narrative synthesis based on types of intervention, including multicomponent and single-component interventions. RESULTS Twenty-four systematic reviews were included in this overview, of which four reviews were of high quality. Multicomponent interventions were the most widely disseminated non-pharmacological strategy, which were effective in preventing delirium with 27 %-54 % reduction in delirium incidence. Additionally, the multicomponent strategy also reduced the incidence of falls and pressure ulcers, and showed trends toward shortening the length of stay and improving cognitive function. Among single-component interventions, physical training, geriatric risk assessment, and reorientation protocol revealed positive effects in delirium prevention. However, the effectiveness of non-pharmacological interventions for treating delirium was limited, and while multicomponent methods had inconsistent impacts on the duration and severity of delirium, single-component methods showed no significant impact. CONCLUSION Non-pharmacological interventions are effective in reducing the incidence of delirium and improving other health outcomes among older patients. However, the effects on the duration and severity of delirium need more evidence to confirm. REGISTRATION NUMBER CRD42022376651 in PROSPERO.

Abstract
Deep Learning (DL) models have received increasing attention in the clinical setting, particularly in intensive care units (ICU). In this context, the interpretability of the outcomes estimated by the DL models is an essential step towards increasing adoption of DL models in clinical practice. To address this challenge, we propose an ante-hoc, interpretable neural network model. Our proposed model, named double self-attention architecture (DSA), uses two attention-based mechanisms, including self-attention and effective attention. It can capture the importance of input variables in general, as well as changes in importance along the time dimension for the outcome of interest. We evaluated our model using two real-world clinical datasets covering 22840 patients in predicting onset of delirium 12 h and 48 h in advance. Additionally, we compare the descriptive performance of our model with three post-hoc interpretable algorithms as well as with the opinion of clinicians based on the published literature and clinical experience. We find that our model covers the majority of the top-10 variables ranked by the other three post-hoc interpretable algorithms as well as the clinical opinion, with the advantage of taking into account both, the dependencies among variables as well as dependencies between varying time-steps. Finally, our results show that our model can improve descriptive performance without sacrificing predictive performance.

Abstract
OBJECTIVES Studies have identified many nursing interventions that can prevent delirium and fall accidents in clinical patients, detect and treat delirium early to prevent functional decline in the patient, shorten hospitalization duration, and lower the death rate. This study aimed to explore delirium care by intensive care unit (ICU) nurses in a medical center of southern Taiwan. METHODS This study conducted 3 semistructured focus group interviews, each for a single medical ICU, involving groups of 6 to 8 nurses each. The nurses were recruited through purposive sampling. This research was approved by an institutional review board in the medical center of southern Taiwan from March 31, 2020, to January 30, 2021. The co-principal investigator described the purpose and process of this study to the participants before they provided their written informed consents. The interviews were conducted in the meeting room and were audiotape recorded. The recordings were transcribed and subject to content analysis to identify the themes of delirium care. RESULTS For nursing interventions of delirium, satisfying the patient's physical needs: comfort care, massages, and early rehabilitation; and psychological care: being presence, communication, and ensuring familial support were included. In terms of environmental interventions for delirium, providing reorientation, music, light, belongings with sentimental value, and audiovisual equipment were included. However, according to the recruited medical ICU nurses, these nonpharmacological interventions, although effective, do not have long-lasting effects. Finally, nurses reported themselves as having been attacked by patients with delirium. Thus, they all agreed that restraining patients with delirium may be necessary, but restraining is a double-edged sword for ICU delirium patients. CONCLUSIONS Research team suggests for future studies to extend their evidence-based findings of physical, psychological, and environmental care for ICU delirium patients toward integrating the efforts of various health care professionals.

Abstract
INTRODUCTION Limited data are available to explore the association between preoperative frailty and cognitive impairment with postoperative delirium among older adults with cancer. We explored this association in a single Comprehensive Cancer Center where postoperative delirium and frailty are assessed in routine care using the Confusion Assessment Method (CAM) and Memorial Sloan Kettering Frailty Index (MSK-FI), respectively. MATERIALS AND METHODS Retrospective study on patients with cancer, aged 65+, who underwent surgery from April 2018 to March 2019 with hospital stay ≥1 day. We used logistic regression with postoperative delirium as the outcome, primary predictor MSK-FI, adjusted for age, operative time, and preoperative albumin. As the MSK-FI includes a component related to cognitive impairment, we additionally evaluated the impact of this component, separately from the rest of the score, on the association between frailty and postoperative delirium. RESULTS Among 1,257 patients with available MSK-FI and CAM measures, 47 patients (3.7%) had postoperative delirium. Increased frailty was associated with increased risk of postoperative delirium (odds ratio [OR] 1.51; 95% confidence interval [CI] 1.26, 1.81; p < 0.001). However, this was largely related to the effect of cognitive impairment (OR 15.29; 95% CI 7.18; 32.56; p < 0.001). In patients with cognitive impairment, the association between frailty and postoperative delirium was not significant (OR 0.97; 95% CI 0.65, 1.44; p-value = 0.9), as having cognitive impairment put patients at high risk for postoperative delirium even without taking into account the other components of the MSK-FI. While the association between frailty and postoperative delirium in patients with intact cognitive function was statistically significant (OR 1.58; 95% CI 1.27, 1.96; p < 0.001), it was not clinically meaningful, particularly considering the low risk of delirium among patients with intact cognitive function (e.g., 1.3% vs 3.2% for MSK-FI 1 vs 3). DISCUSSION Cognitive function should be a greater focus than frailty, as measured by the MSK-FI, in preoperative assessment for the prediction of postoperative delirium.

Abstract
OBJECTIVES to inform development of a core outcome set, we evaluated outcomes, definitions, measures and measurement time points in clinical trials of interventions to prevent and/or treat delirium in older adults resident in long-term care (LTC). DATA SOURCES we searched electronic databases, systematic review repositories and trial registries (1980 to 10 December 2021). STUDY SELECTION AND DATA EXTRACTION we included randomised, quasi-randomised and non-randomised intervention studies. We extracted data on study characteristics, outcomes and measurement features. We assessed outcome reporting quality using the MOMENT study scoring system. We categorised outcomes using the Core Outcome Measures in Effectiveness Trials taxonomy. DATA SYNTHESIS we identified 18 studies recruiting 5,639 participants. All evaluated non-pharmacological interventions; most (16 studies, 89%) addressed delirium prevention. We identified 12 delirium-specific outcomes (mean [SD] 2.4 [1.5] per study), of which delirium incidence (14 studies, 78%) and severity (6 studies, 33%) were most common. We found heterogeneity in description of outcomes and measurement time points. The Confusion Assessment Method (three versions) was the most common measure used to ascertain delirium incidence (7 of 14 studies, 50%). We identified 25 non-delirium specific outcomes (mean [SD] 4.0 [2.3] per study), with hospital admission the most commonly reported (9 studies, 50%). CONCLUSIONS we identified few studies of interventions for the prevention or treatment of delirium in older adults resident in LTC. These studies were heterogeneous in the outcomes reported and measures used. These data inform the consensus-building stage of a core outcome set.

J Am Geriatr Soc 2022; 70:2988-2995. [PMID: 35775444 PMCID: PMC9588494 DOI: 10.1111/jgs.17947] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2022] [Revised: 06/10/2022] [Accepted: 06/15/2022] [Indexed: 01/10/2023]
Abstract
BACKGROUND Hospital visitation restrictions during the COVID-19 pandemic prompted concerns about unintended consequences for older patients, including an increased incidence of delirium and agitation. While first-line interventions for these conditions are non-pharmacologic, a lack of family support could result in increased use of benzodiazepines and antipsychotics, which are associated with poor outcomes in older adults. Little is known about the association of visitation policies with use of these medications among older adults. METHODS We conducted a retrospective cross-sectional study among adults aged ≥65 hospitalized from March 1 through May 31, 2020 at four hospitals in the Mid-Atlantic. The dates of onset of visitation restrictions (i.e., hospital-wide guidelines barring visitors) were collected from hospital administrators. Outcomes were use of benzodiazepines and antipsychotics, assessed using patient-level electronic health record data. Using multivariable logistic regression with hospital and study-day fixed effects, the quasi-experimental study design leveraged the staggered onset of visitation restrictions across the hospitals to measure the odds of receiving each medication when visitors were versus were not allowed. RESULTS Among 2931 patients, mean age was 76.6 years (SD, 8.3), 51.6% were female, 58.6% white, 32.5% black, and 2.6% Hispanic. Overall, 924 (31.5%) patients received a benzodiazepine and 298 (10.2%) an antipsychotic. The adjusted odds of benzodiazepine use was lower on days when visitors were versus were not allowed (adjusted odds ratio [AOR], 0.62; 95% CI, 0.39, 0.99). Antipsychotic use did not significantly differ between days when visitors were versus were not allowed (AOR, 0.98; 95% CI, 0.43, 2.21). CONCLUSIONS Among older patients hospitalized during the first wave of the pandemic, benzodiazepine use was lower on days when visitors were allowed. These findings suggest that the presence of caregivers impacts use of potentially inappropriate medications among hospitalized older adults, supporting efforts to recognize caregivers as essential members of the care team.

Abstract
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.

Non-Pharmacological Nursing Interventions to Prevent Delirium in ICU Patients-An Umbrella Review with Implications for Evidence-Based Practice. J Pers Med 2022; 12:760. [PMID: 35629183 PMCID: PMC9143487 DOI: 10.3390/jpm12050760] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2022] [Revised: 05/02/2022] [Accepted: 05/05/2022] [Indexed: 02/06/2023] Open
Abstract
Delirium in ICU patients is a complication associated with many adverse consequences. Given the high prevalence of this complication in critically ill patients, it is essential to develop and implement an effective management protocol to prevent delirium. Given that the cause of delirium is multifactorial, non-pharmacological multicomponent interventions are promising strategies for delirium prevention. (1) Background: To identify and evaluate published systematic review on non-pharmacological nursing interventions to prevent delirium in intensive care unit patients. (2) Methods: An umbrella review guided by the Joanna Briggs Institute was utilized. Data were obtained from PubMed, Scopus, EBSCO, Web of Science, Cochrane Library, and Google Scholar. The last search was conducted on 1 May 2022. (3) Results: Fourteen reviews met the inclusion criteria. Multicomponent interventions are the most promising methods in the fight against delirium. The patient's family is an important part of the process and should be included in the delirium prevention scheme. Light therapy can improve the patient's circadian rhythm and thus contribute to reducing the incidence of delirium. (4) Conclusions: Non-pharmacological nursing interventions may be effective in preventing and reducing the duration of delirium in ICU patients.

Anticholinergic Drug Exposure Increases the Risk of Delirium in Older Patients Undergoing Elective Surgery. Front Med (Lausanne) 2022; 9:871229. [PMID: 35602472 PMCID: PMC9121116 DOI: 10.3389/fmed.2022.871229] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2022] [Accepted: 03/29/2022] [Indexed: 11/26/2022] Open
Abstract
Introduction Postoperative delirium (POD) is a common and serious adverse event of surgery in older people. Because of its great impact on patients' safety and quality of life, identification of modifiable risk factors could be useful. Although preoperative medication intake is assumed to be an important modifiable risk factor, the impact of anticholinergic drugs on the occurrence of POD seems underestimated in elective surgery. The aim of this study was to investigate the association between preoperative anticholinergic burden and POD. We hypothesized that a high preoperative anticholinergic burden is an independent, potentially modifiable predisposing and precipitating factor of POD in older people. Methods Between November 2017 and April 2019, 1,470 patients of 70 years and older undergoing elective orthopedic, general, cardiac, or vascular surgery were recruited in the randomized, prospective, multicenter PAWEL trial. Anticholinergic burden of a sub-cohort of 899 patients, who did not receive a multimodal intervention for preventing POD, was assessed by two different tools at hospital admission: The established Anticholinergic Risk Scale (ARS) and the recently developed Anticholinergic Burden Score (ABS). POD was detected by confusion assessment method (CAM) and a validated post discharge medical record review. Logistic regression analyses were performed to evaluate the association between anticholinergic burden and POD. Results POD was observed in 210 of 899 patients (23.4%). Both ARS and ABS were independently associated with POD. The association persisted after adjustment for relevant confounding factors such as age, sex, comorbidities, preoperative cognitive and physical status, number of prescribed drugs, surgery time, type of surgery and anesthesia, usage of heart-lung-machine, and treatment in intensive care unit. If a patient was taking one of the 56 drugs listed in the ABS, risk for POD was 2.7-fold higher (OR = 2.74, 95% CI = 1.55–4.94) and 1.5-fold higher per additional point on the ARS (OR = 1.54, 95% CI = 1.15–2.02). Conclusion Preoperative anticholinergic drug exposure measured by ARS or ABS was independently associated with POD in older patients undergoing elective surgery. Therefore, identification, discontinuation or substitution of anticholinergic medication prior to surgery may be a promising approach to reduce the risk of POD in older patients.

Effects of non-pharmacological interventions for preventing delirium in general ward inpatients: A systematic review & meta-analysis of randomized controlled trials. PLoS One 2022; 17:e0268024. [PMID: 35522654 PMCID: PMC9075647 DOI: 10.1371/journal.pone.0268024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2021] [Accepted: 04/21/2022] [Indexed: 11/29/2022] Open
Abstract
The purpose of this study was to identify the types and contents of non-pharmacological delirium prevention interventions applied to inpatients in general wards, and to verified the effectiveness of the interventions on the incidence of delirium. We performed an extensive search of bibliographic databases and registries (CENTRAL, MEDLINE, EMBASE, CINAHL, ClinicalTrials.gov and WHO International Clinical Trials Registry Platform, PubMed and Google Scholar, and Korean DB such as RISS, DBpia, KISS, NDSL and KCI) using terms to identify delirium, prevention, and non-pharmacological. We searched all databases from their inception to January 2021 and imposed restriction on language of publication in English and Korean. We included studies if they were conducted as all types of randomized controlled trials (RCT), involving adult patients aged 19 years or more who were admitted to a general ward. We included trials comparing non-pharmacological intervention versus usual care. The entire process of data selection and extraction, assessment of risk of bias with ROB2.O was independently performed by three researchers. The estimated effect size was an odds ratio (OR) and 95% confidence interval. The fixed effects model and general inverse variance estimation method were adopted. The type of non-pharmacological delirium prevention interventions for inpatients in general ward was mainly multi-component intervention to correct delirium risk factors. The content and intensity of non-pharmacological interventions varied greatly depending on the characteristics of the patient and the clinical situation. As a result of the meta-analysis, non-pharmacological multi-component intervention was effective in reducing the incidence of delirium, and it was confirmed that it was effective in reducing the incidence of delirium in both the internal and surgical wards. It was confirmed by quantitative evidence that non-pharmacological interventions, especially multi-component interventions, were effective in preventing delirium in general ward inpatients.

Abstract
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.

Abstract
BACKGROUND Evaluation of the effectiveness of melatonin is necessary to prevent the development of delirium in hospitalized patients. Melatonin (N-acetyl-5-methoxytryptamine) is a hormone produced by the pineal gland of the brain from the amino acid tryptophan. Synthetic melatonin supplements have been used for various medical conditions, especially sleep-related diseases, and have proved to be successful.
AIM To determine the effect of melatonin on the prevention of delirium in hospitalized patients.
METHODS A literature search of the CNKI, Wanfang Database, VIP Database, China Biomedical Literature Database, PubMed, Embase, Cochrane Library, Web of Science, and other databases was conducted. The CNKI, Wanfang Database, VIP Database (VIP), and China Biomedical Literature Database were searched for Chinese studies, and PubMed, Embase, Cochrane Library, Web of Science and other databases were searched for international studies. It will be established in June 2021 in a randomized controlled trial (RCT) whether melatonin treatment for 6 mo prevents delirium in hospitalized patients. Literature screening, quality review, and data extraction were carried out using the Cochrane Manual 5.1.0 systematic evaluation method, and Stata 15.0 software and Review Manager 5.3 were used for meta-analysis and processing.
RESULTS A total of 18 new RCT articles and 18 experimental subjects were identified. The results of the meta-analysis showed that following the occurrence of delirium, melatonin reduced the incidence of delirium in patients (RR = 0.69, 95%CI: 0.60-0.80), which is of significance, but heterogeneity was significant I2 = 62%. Subgroup analysis was performed to examine the source of heterogeneity, and it was found that different patient types were the source of heterogeneity; the research on subgroup analysis was of high quality and homogeneous. To determine the reliability and robustness of the research results, a sensitivity analysis was carried out. The results showed that after excluding individual studies one by one, the effect size was still within 95%CI, which strengthened the reliability of the original meta-analysis results. Melatonin has a significant preventive effect on delirium in hospitalized medical patients [RR = 0.60, 95%CI: 0.47-0.76), P < 0.001].
CONCLUSION Melatonin can reduce the rate of delirium in medical patients, and the role of melatonin in reducing the incidence of delirium in surgical patients and critical care unit patients requires further study.

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

Abstract
BACKGROUND Delirium is common in elderly patients with hip fracture. Although several multicomponent care pathways have been developed, few nurse-led perioperative multicomponent programs have been evaluated. AIMS The current study aimed to evaluate the effect of a nurse-led perioperative multicomponent interdisciplinary program in preventing postoperative delirium in elderly patients with hip fracture. METHOD The participants in the usual care group were recruited from March 2012 to February 2013, and these in the experimental group were recruited from May 2013 to June 2014. The participants in the usual care group (n = 174) received usual medical and nursing care from admission to hospital discharge and the participants in the experimental group (n = 192) received the nurse-led perioperative multicomponent interdisciplinary intervention. The STROBE checklist was used to report this study. RESULTS There were no statistical differences between the two cohorts in terms of the baseline data such as gender, age, fracture type, and so on. The experimental group had a lower incidence of delirium and postoperative hypoxia than the usual care group. No statistical differences in terms of delirium severity, delirium duration, and mean hospitalization length were observed. CONCLUSIONS The nurse-led perioperative multicomponent interdisciplinary program described in the current study is feasible and effective in reducing the incidence of postoperative delirium in elderly patients with hip fracture.

Abstract
Delirium is a term used to describe an array of symptoms that indicate a disruption in cerebral metabolism, a condition that is often under-recognised, leading to delayed interventions. The condition is a common cause of older adults presenting in hospital, with significant morbidity and mortality associated with increased length of stay. A case study is used to illustrate the use of a diagnostic algorithm for older adults presenting with delirium to an advanced nurse practitioner (ANP)-led service. The clinical decision pathway provides four differential diagnoses, using the case study to put the decision-making process in context. The article demonstrates the ability of the ANP to practise at a high level of expertise as an autonomous practitioner and shows how the pathway supports the nurse to reach an accurate diagnosis. It shows that prompt and accurate diagnosis of delirium in older adults is crucial to avoiding the complications and cognitive decline associated with the condition.

Abstract
OBJECTIVES To determine the incidence of falls, risk factors, and adverse outcomes, among patients admitted to the ICU. DESIGN Retrospective cohort study. SETTING Seventeen ICUs in Alberta, Canada. PATIENTS Seventy-three thousand four hundred ninety-five consecutive adult patient admissions between January 1, 2014, and December 31, 2019. MEASUREMENTS AND MAIN RESULTS A mixed-effects negative binomial regression model was used to examine risk factors associated with falls. Linear and logistic regression models were used to evaluate adverse outcomes. Six hundred forty patients experienced 710 falls over 398,223 patient days (incidence rate of 1.78 falls per 1,000 patient days [95% CI, 1.65-1.91]). The daily incidence of falls increased during the ICU stay (e.g., day 1 vs day 7; 0.51 vs 2.43 falls per 1,000 patient days) and varied significantly between ICUs (range, 0.37-4.64 falls per 1,000 patient days). Male sex (incidence rate ratio [IRR], 1.37; 95% CI, 1.15-1.63), previous invasive mechanical ventilation (IRR, 1.82; 95% CI, 1.40-2.38), previous sedative and analgesic medication infusions (IRR, 1.60; 95% CI, 1.15-2.24), delirium (IRR, 3.85; 95% CI, 3.23-4.58), and patient mobilization (IRR, 1.26; 95% CI, 1.21-1.30) were risk factors for falling. Falls were associated with longer ICU (ratio of means [RM], 3.10; 95% CI, 2.86-3.36) and hospital (RM, 2.21; 95% CI, 2.01-2.42) stays, but lower odds of death in the ICU (odds ratio [OR], 0.09; 95% CI, 0.05-0.17) and hospital (OR, 0.21; 95% CI, 0.14-0.30). CONCLUSIONS We observed that among ICU patients, falls occur frequently, vary substantially between ICUs, and are associated with modifiable risk factors, longer ICU and hospital stays, and lower risk of death. Our study suggests that fall prevention strategies should be considered for critically ill patients admitted to ICU.

Non-pharmacological strategies have been shown to be effective in the prevention and management of delirium. This study aimed to determine the effectiveness of art therapy as part of a multicomponent intervention in preventing and managing delirium in hospitalized older patients. METHODS 138 patients at risk of developing delirium were included and received art therapy twice daily for 25 min using a mobile atelier. 107 participants were included in the final analysis (N = 53 intervention, N = 54 control). The primary outcome was the effectiveness of art therapy in preventing delirium. The secondary outcome was to determine its impact on duration of delirium in patients with existing delirium. Delirium was assessed using the Nursing delirium Screening Scale (Nu-DESC). RESULTS 8 patients (7.5%) developed new onset delirium after admission, equally distributed among control and intervention group. Therefore, no valid statistical analysis could be performed. There was a statistically non-significant decrease in the duration of delirium in the intervention group (4 days, IQR 2.25-8.75) compared to the control group (7 days, IQR 5-10), Mann-Whitney-U-Test p-value = 0.26. After stratifying by dementia diagnosis on admission, the non-significant decrease in duration of delirium in the intervention group was more apparent in patients without dementia. CONCLUSION Findings from this study showed that the integration of art therapy as part of a multicomponent intervention in delirium management is feasible, and can reduce duration of delirium among hospitalized older adults.

Lim XM, Lim ZHT, Ignacio J. Nurses' experiences in the management of delirium among older persons in acute care ward settings: A qualitative systematic review and meta-aggregation. Int J Nurs Stud 2021; 127:104157. [PMID: 35033990 DOI: 10.1016/j.ijnurstu.2021.104157] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2021] [Revised: 12/06/2021] [Accepted: 12/09/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND Delirium is a multifactorial syndrome closely associated with negative hospitalisation outcomes. Given the global growth of the ageing population, delirium becomes increasingly prevalent among older persons. Nurses play a pivotal role in delirium management and receive direct impacts of delirious presentations. Yet, there is a dearth of literature reviewing nurses' experiences. OBJECTIVE To synthesise the best available evidence exploring nurses' experiences in managing delirium of older persons in acute care wards. DESIGN Systematic review of qualitative studies and meta-aggregation. DATA SOURCES Published and unpublished literature between January 2010 and December 2020 were identified from PubMed, Embase, Web of Science, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Scopus, PsycINFO and ProQuest. REVIEW METHODS A systematic search strategy was applied in October 2020, with an update in January 2021. Two reviewers independently screened the titles and abstracts and selected the eligible studies after reading the full texts. This review included studies focusing on licensed nurses providing care to patients aged 65 and above, having any type of delirium during their hospitalisation stays in acute care settings. Studies included are qualitative papers with research designs such as phenomenology, ethnography, qualitative descriptive and grounded theory. The eligible studies were appraised independently using The JBI Critical Appraisal Checklist for Qualitative Research. Data of included studies were extracted by two independent reviewers using a standardised form. Findings were synthesised by the meta-aggregative approach. RESULTS Thirty-one papers that considered nurses' (n = 464) experiences in managing older persons' delirium were included. A total of 375 findings were extracted, aggregated into 23 categories, and developed 5 synthesised findings: (i) delirium detection could be hindered when nurses possess a narrowed view of delirium, (ii) nurses navigate through complexity when providing multi-faceted care, (iii) nurses carry personal emotions, assumptions, and identities, (iv) various stakeholders have double-edged influences, and (v) nurses display preferences in their learning needs. CONCLUSION This review informed about nurses' perceptions of delirium, delirious older persons, and their nursing management which were specific to older persons and acute care settings. Nurses should practise self-awareness regarding their own knowledge and attitudes while performing delirium management in older adults. Meanwhile, healthcare professionals and policymakers should make a concerted effort in cultivating a better working environment. Future research of delirium care that specifically investigates with a geriatric perspective would better contribute to the improvement of evidence-based nursing practices for older persons.

Abstract
AIM This study aims to evaluate the publications on delirium by using bibliometric analysis. METHODOLOGY The Scopus database was evaluated for publications on delirium, during the period of 2001-20. The search results were analyzed for the origin of country, origin of institution, authorship, collaborations, type of article, source of funding, and number of citations. RESULTS The searches of Scopus database yielded 22,941 publications, originating from 139 countries. Compared to the decade of 2001-2010, the number of publications on delirium doubled in the decade of 2011-2020. The majority of the papers were research articles (58.26%), and the papers were cited for mean number of 20.53 times. Only a small proportion of the papers were based on funding (13.14%). Maximum number of papers emerged from United States of America. In terms of institutional affiliations, among the authors from top 20 institutes, 15 were from United States, 2 from Netherlands and 1 each from Canada, Germany and United Kingdom. In terms of authors, the research productivity of the top 20 most productive authors varied from 172 to 612 publications with 12 authors belonging to United States, 2 from Italy and 1 each from Canada, Greece, India, Ireland, Netherland and the United Kingdom. The maximum number of papers were published in Journal of the American Geriatric Society and based on the number of citations the New England Journal of Medicine was the most impactful journal. CONCLUSION Over the years number of publications on delirium have increased, majority of the publications have emerged from United States.

Abstract
BACKGROUND Delirium is an acute neuropsychological disorder that is common in hospitalised patients. It can be distressing to patients and carers and it is associated with serious adverse outcomes. Treatment options for established delirium are limited and so prevention of delirium is desirable. Non-pharmacological interventions are thought to be important in delirium prevention. OBJECTIVES: To assess the effectiveness of non-pharmacological interventions designed to prevent delirium in hospitalised patients outside intensive care units (ICU). SEARCH METHODS We searched ALOIS, the specialised register of the Cochrane Dementia and Cognitive Improvement Group, with additional searches conducted in MEDLINE, Embase, PsycINFO, CINAHL, LILACS, Web of Science Core Collection, ClinicalTrials.gov and the World Health Organization Portal/ICTRP to 16 September 2020. There were no language or date restrictions applied to the electronic searches, and no methodological filters were used to restrict the search. SELECTION CRITERIA We included randomised controlled trials (RCTs) of single and multicomponent non-pharmacological interventions for preventing delirium in hospitalised adults cared for outside intensive care or high dependency settings. We only included non-pharmacological interventions which were designed and implemented to prevent delirium. DATA COLLECTION AND ANALYSIS: Two review authors independently examined titles and abstracts identified by the search for eligibility and extracted data from full-text articles. Any disagreements on eligibility and inclusion were resolved by consensus. We used standard Cochrane methodological procedures. The primary outcomes were: incidence of delirium; inpatient and later mortality; and new diagnosis of dementia. We included secondary and adverse outcomes as pre-specified in the review protocol. We used risk ratios (RRs) as measures of treatment effect for dichotomous outcomes and between-group mean differences for continuous outcomes. The certainty of the evidence was assessed using GRADE. A complementary exploratory analysis was undertaker using a Bayesian component network meta-analysis fixed-effect model to evaluate the comparative effectiveness of the individual components of multicomponent interventions and describe which components were most strongly associated with reducing the incidence of delirium. MAIN RESULTS We included 22 RCTs that recruited a total of 5718 adult participants. Fourteen trials compared a multicomponent delirium prevention intervention with usual care. Two trials compared liberal and restrictive blood transfusion thresholds. The remaining six trials each investigated a different non-pharmacological intervention. Incidence of delirium was reported in all studies. Using the Cochrane risk of bias tool, we identified risks of bias in all included trials. All were at high risk of performance bias as participants and personnel were not blinded to the interventions. Nine trials were at high risk of detection bias due to lack of blinding of outcome assessors and three more were at unclear risk in this domain. Pooled data showed that multi-component non-pharmacological interventions probably reduce the incidence of delirium compared to usual care (10.5% incidence in the intervention group, compared to 18.4% in the control group, risk ratio (RR) 0.57, 95% confidence interval (CI) 0.46 to 0.71, I2 = 39%; 14 studies; 3693 participants; moderate-certainty evidence, downgraded due to risk of bias). There may be little or no effect of multicomponent interventions on inpatient mortality compared to usual care (5.2% in the intervention group, compared to 4.5% in the control group, RR 1.17, 95% CI 0.79 to 1.74, I2 = 15%; 10 studies; 2640 participants; low-certainty evidence downgraded due to inconsistency and imprecision). No studies of multicomponent interventions reported data on new diagnoses of dementia. Multicomponent interventions may result in a small reduction of around a day in the duration of a delirium episode (mean difference (MD) -0.93, 95% CI -2.01 to 0.14 days, I2 = 65%; 351 participants; low-certainty evidence downgraded due to risk of bias and imprecision). The evidence is very uncertain about the effect of multicomponent interventions on delirium severity (standardised mean difference (SMD) -0.49, 95% CI -1.13 to 0.14, I2=64%; 147 participants; very low-certainty evidence downgraded due to risk of bias and serious imprecision). Multicomponent interventions may result in a reduction in hospital length of stay compared to usual care (MD -1.30 days, 95% CI -2.56 to -0.04 days, I2=91%; 3351 participants; low-certainty evidence downgraded due to risk of bias and inconsistency), but little to no difference in new care home admission at the time of hospital discharge (RR 0.77, 95% CI 0.55 to 1.07; 536 participants; low-certainty evidence downgraded due to risk of bias and imprecision). Reporting of other adverse outcomes was limited. Our exploratory component network meta-analysis found that re-orientation (including use of familiar objects), cognitive stimulation and sleep hygiene were associated with reduced risk of incident delirium. Attention to nutrition and hydration, oxygenation, medication review, assessment of mood and bowel and bladder care were probably associated with a reduction in incident delirium but estimates included the possibility of no benefit or harm. Reducing sensory deprivation, identification of infection, mobilisation and pain control all had summary estimates that suggested potential increases in delirium incidence, but the uncertainty in the estimates was substantial. Evidence from two trials suggests that use of a liberal transfusion threshold over a restrictive transfusion threshold probably results in little to no difference in incident delirium (RR 0.92, 95% CI 0.62 to 1.36; I2 = 9%; 294 participants; moderate-certainty evidence downgraded due to risk of bias). Six other interventions were examined, but evidence for each was limited to single studies and we identified no evidence of delirium prevention. AUTHORS' CONCLUSIONS: There is moderate-certainty evidence regarding the benefit of multicomponent non-pharmacological interventions for the prevention of delirium in hospitalised adults, estimated to reduce incidence by 43% compared to usual care. We found no evidence of an effect on mortality. There is emerging evidence that these interventions may reduce hospital length of stay, with a trend towards reduced delirium duration, although the effect on delirium severity remains uncertain. Further research should focus on implementation and detailed analysis of the components of the interventions to support more effective, tailored practice recommendations.

Abstract
BACKGROUND Delirium is a significant cause of morbidity and mortality among older people admitted to both acute and long-term care facilities (LTCFs). Multicomponent interventions have been shown to reduce delirium incidence in the acute care setting (30-73%) by acting on modifiable risk factors. Little work, however, has focused on using this approach to reduce delirium incidence in LTCFs. METHODS The objective is to assess the effectiveness of the multicomponent PREPARED Trial intervention in reducing the following primary outcomes: incidence, severity, duration, and frequency of delirium episodes in cognitively impaired residents. This 4-year, parallel-design, cluster randomized study will involve nursing staff and residents in 45-50 LTCFs in Montreal, Canada. Participating public and private LTCFs (clusters) that provide 24-h nursing care will be assigned to either the PREPARED Trial intervention or the control (usual care) arm of the study using a covariate constrained randomization procedure. Approximately 400-600 LTC residents aged 65 and older with dementia and/or cognitive impairment will be enrolled in the study and followed for 18 weeks. Residents must be at risk of delirium, delirium-free at baseline and have resided at the facility for at least 2 weeks. Residents who are unable to communicate verbally, have a history of specific psychiatric conditions, or are receiving end-of-life care will be excluded. The PREPARED Trial intervention consists of four main components: a decision tree, an instruction manual, a training package, and a toolkit. Primary study outcomes will be assessed weekly. Functional autonomy and cognitive levels will be assessed at the beginning and end of follow-up, while information pertaining to modifiable delirium risk factors, medical consultations, and facility transfers will be collected retrospectively for the duration of the follow-up period. Primary outcomes will be reported at the level of intervention assignment. All researchers analyzing the data will be blinded to group allocation. DISCUSSION This large-scale intervention study will contribute significantly to the development of evidence-based clinical guidelines for delirium prevention in this frail elderly population, as it will be the first to evaluate the efficacy of a multicomponent delirium prevention program translated into LTC clinical practice on a large scale.

Abstract
OBJECTIVES To determine the efficacy of a multicomponent nursing program to prevent delirium in critically ill patients. METHODS Parallel controlled randomized clinical trial to prevent delirium in 81 critically ill patients: 41 in the control group and 40 in the intervention group (intervention: spatial and temporal guidance, visual stimulus, auditive stimulus, and family support). Participants were recruited from September 2017 to March 2018 in the university hospital Los Comuneros, Bucaramanga, Colombia. Clinical Trials record NCT03215745. RESULTS The incidence of delirium was 5% in the intervention group and 24% in the control group. The relative risk was 0.20 (95% CI 0.05 to 0.88). The absolute risk reduction was 19.39% (95% CI 4.61 to 34.17) and the number needed to treat was 5 (95 CI % 3 to 26%). CONCLUSION The multicomponent nursing program is efficient to prevent delirium in critically ill patients.

Abstract
Delirium is an emergency and can have serious consequences. On the arrival at the emergency room of an elderly person, it should be systematically checked for confusional syndrome. If it is confirmed, a systematic and rapid etiological assessment carried out in the emergency room allows the identification of predisposing and precipitating factors. Therapeutic management is urgent, and includes treatment of the causes in the first instance.

Abstract
BACKGROUND Delirium prevention is crucial, especially in critically ill patients. Nonpharmacological multicomponent interventions for preventing delirium are increasingly recommended and technology-based interventions have been developed to support them. Despite the increasing number and diversity in technology-based interventions, there has been no systematic effort to create an overview of these interventions for in-hospital delirium prevention and reduction. OBJECTIVE This systematic scoping review was carried out to answer the following questions: (1) what are the technologies currently used in nonpharmacological technology-based interventions for preventing and reducing delirium? and (2) what are the strategies underlying these currently used technologies? METHODS A systematic search was conducted in Scopus and Embase between 2015 and 2020. A selection was made in line with the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). Studies were eligible if they contained any type of technology-based interventions and assessed delirium-/risk factor-related outcome measures in a hospital setting. Data extraction and quality assessment were performed using a predesigned data form. RESULTS A total of 31 studies were included and analyzed focusing on the types of technology and the strategies used in the interventions. Our review revealed 8 different technology types and 14 strategies that were categorized into the following 7 pathways: (1) restore circadian rhythm, (2) activate the body, (3) activate the mind, (4) induce relaxation, (5) provide a sense of security, (6) provide a sense of control, and (7) provide a sense of being connected. For all technology types, significant positive effects were found on either or both direct and indirect delirium outcomes. Several similarities were found across effective interventions: using a multicomponent approach or including components comforting the psychological needs of patients (eg, familiarity, distraction, soothing elements). CONCLUSIONS Technology-based interventions have a high potential when multidimensional needs of patients (eg, physical, cognitive, emotional) are incorporated. The 7 pathways pinpoint starting points for building more effective technology-based interventions. Opportunities were discussed for transforming the intensive care unit into a healing environment as a powerful tool to prevent delirium.

Abstract
BACKGROUND Delirium is an acute neuropsychological disorder that is common in hospitalised patients. It can be distressing to patients and carers and it is associated with serious adverse outcomes. Treatment options for established delirium are limited and so prevention of delirium is desirable. Non-pharmacological interventions are thought to be important in delirium prevention. OBJECTIVES: To assess the effectiveness of non-pharmacological interventions designed to prevent delirium in hospitalised patients outside intensive care units (ICU). SEARCH METHODS We searched ALOIS, the specialised register of the Cochrane Dementia and Cognitive Improvement Group, with additional searches conducted in MEDLINE, Embase, PsycINFO, CINAHL, LILACS, Web of Science Core Collection, ClinicalTrials.gov and the World Health Organization Portal/ICTRP to 16 September 2020. There were no language or date restrictions applied to the electronic searches, and no methodological filters were used to restrict the search. SELECTION CRITERIA We included randomised controlled trials (RCTs) of single and multicomponent non-pharmacological interventions for preventing delirium in hospitalised adults cared for outside intensive care or high dependency settings. We only included non-pharmacological interventions which were designed and implemented to prevent delirium. DATA COLLECTION AND ANALYSIS: Two review authors independently examined titles and abstracts identified by the search for eligibility and extracted data from full-text articles. Any disagreements on eligibility and inclusion were resolved by consensus. We used standard Cochrane methodological procedures. The primary outcomes were: incidence of delirium; inpatient and later mortality; and new diagnosis of dementia. We included secondary and adverse outcomes as pre-specified in the review protocol. We used risk ratios (RRs) as measures of treatment effect for dichotomous outcomes and between-group mean differences for continuous outcomes. The certainty of the evidence was assessed using GRADE. A complementary exploratory analysis was undertaker using a Bayesian component network meta-analysis fixed-effect model to evaluate the comparative effectiveness of the individual components of multicomponent interventions and describe which components were most strongly associated with reducing the incidence of delirium. MAIN RESULTS We included 22 RCTs that recruited a total of 5718 adult participants. Fourteen trials compared a multicomponent delirium prevention intervention with usual care. Two trials compared liberal and restrictive blood transfusion thresholds. The remaining six trials each investigated a different non-pharmacological intervention. Incidence of delirium was reported in all studies. Using the Cochrane risk of bias tool, we identified risks of bias in all included trials. All were at high risk of performance bias as participants and personnel were not blinded to the interventions. Nine trials were at high risk of detection bias due to lack of blinding of outcome assessors and three more were at unclear risk in this domain. Pooled data showed that multi-component non-pharmacological interventions probably reduce the incidence of delirium compared to usual care (10.5% incidence in the intervention group, compared to 18.4% in the control group, risk ratio (RR) 0.57, 95% confidence interval (CI) 0.46 to 0.71, I2 = 39%; 14 studies; 3693 participants; moderate-certainty evidence, downgraded due to risk of bias). There may be little or no effect of multicomponent interventions on inpatient mortality compared to usual care (5.2% in the intervention group, compared to 4.5% in the control group, RR 1.17, 95% CI 0.79 to 1.74, I2 = 15%; 10 studies; 2640 participants; low-certainty evidence downgraded due to inconsistency and imprecision). No studies of multicomponent interventions reported data on new diagnoses of dementia. Multicomponent interventions may result in a small reduction of around a day in the duration of a delirium episode (mean difference (MD) -0.93, 95% CI -2.01 to 0.14 days, I2 = 65%; 351 participants; low-certainty evidence downgraded due to risk of bias and imprecision). The evidence is very uncertain about the effect of multicomponent interventions on delirium severity (standardised mean difference (SMD) -0.49, 95% CI -1.13 to 0.14, I2=64%; 147 participants; very low-certainty evidence downgraded due to risk of bias and serious imprecision). Multicomponent interventions may result in a reduction in hospital length of stay compared to usual care (MD -1.30 days, 95% CI -2.56 to -0.04 days, I2=91%; 3351 participants; low-certainty evidence downgraded due to risk of bias and inconsistency), but little to no difference in new care home admission at the time of hospital discharge (RR 0.77, 95% CI 0.55 to 1.07; 536 participants; low-certainty evidence downgraded due to risk of bias and imprecision). Reporting of other adverse outcomes was limited. Our exploratory component network meta-analysis found that re-orientation (including use of familiar objects), cognitive stimulation and sleep hygiene were associated with reduced risk of incident delirium. Attention to nutrition and hydration, oxygenation, medication review, assessment of mood and bowel and bladder care were probably associated with a reduction in incident delirium but estimates included the possibility of no benefit or harm. Reducing sensory deprivation, identification of infection, mobilisation and pain control all had summary estimates that suggested potential increases in delirium incidence, but the uncertainty in the estimates was substantial. Evidence from two trials suggests that use of a liberal transfusion threshold over a restrictive transfusion threshold probably results in little to no difference in incident delirium (RR 0.92, 95% CI 0.62 to 1.36; I2 = 9%; 294 participants; moderate-certainty evidence downgraded due to risk of bias). Six other interventions were examined, but evidence for each was limited to single studies and we identified no evidence of delirium prevention. AUTHORS' CONCLUSIONS: There is moderate-certainty evidence regarding the benefit of multicomponent non-pharmacological interventions for the prevention of delirium in hospitalised adults, estimated to reduce incidence by 43% compared to usual care. We found no evidence of an effect on mortality. There is emerging evidence that these interventions may reduce hospital length of stay, with a trend towards reduced delirium duration, although the effect on delirium severity remains uncertain. Further research should focus on implementation and detailed analysis of the components of the interventions to support more effective, tailored practice recommendations.

Abstract
OBJECTIVES To explore factors associated with decision-making of nurses and doctors in prescribing and administering as required antipsychotic medications to older people with delirium. DESIGN Qualitative descriptive. SETTING Two acute care hospital organisations in Melbourne, Australia. PARTICIPANTS Nurses and doctors were invited to participate. Semi-structured focus groups and individual interviews were conducted between May 2019 and March 2020. Interviews were audio-recorded and transcribed verbatim. Data were analysed using thematic analysis. RESULTS Participants were 42 health professionals; n=25 nurses and n=17 doctors. Themes relating to decisions to use antipsychotic medication were: safety; a last resort; nursing workload; a dilemma to medicate; and anticipating worsening behaviours. Nurses and doctors described experiencing pressures when trying to manage hyperactive behaviours. Safety was a major concern leading to the decision to use antipsychotics. Antipsychotics were often used as chemical restraints to 'sedate' a patient with delirium because nurses 'can't do their job'. Results also indicated that nurses had influence over doctors' decisions despite nurses being unaware of this influence. Health professionals' descriptions are illustrated in a decision-making flowchart that identifies how nurses and doctors navigated decisions regarding prescription and administration of antipsychotic medications. CONCLUSIONS The decision to prescribe and administer antipsychotic medications for people with delirium is complex as nurses and doctors must navigate multiple factors before making the decision. Collaborative support and multidisciplinary teamwork are required by both nurses and doctors to optimally care for people with delirium. Decision-making support for nurses and doctors may also help to navigate the multiple factors that influence the decision to prescribe antipsychotics.

Abstract
BACKGROUND Delirium occurs frequently in acute internal medicine wards and may worsen the patient's prognosis; it deserves a fast, systematic screening tool. OBJECTIVE Develop a delirium screening score for inpatients admitted to acute internal medicine wards. DESIGN A monocentric prospective study between November 2019 and January 2020. PARTICIPANTS Two hundred and seventeen adult inpatients. MAIN MEASURES Within 48 h of hospital admission, physicians administered an index test to participants which explored potential predictors associated with the fluctuation of mental state, inattention, disorganised thinking and altered level of consciousness. On the same day, patients underwent a neuropsychological evaluation (reference standard) to assess for delirium. The score was constructed using a backward stepwise logistic regression strategy. Areas under the receiver operating curves (AUC) and calibration curves were drawn to calculate the score's performance. The score was tested on subgroups determined by age, sex and cognitive status. RESULTS The AL-O-A score ("abnormal or fluctuating ALertness, temporospatial Orientation and off-target Answers") showed excellent apparent (AUC 0.95 (95% CI 0.91-0.99)) and optimism-corrected discrimination (AUC 0.92 (95% CI 0.89-0.96)). It performed equally well in subgroups with and without cognitive impairment (AUC 0.93 (95% CI 0.88-0.99) vs 0.92 (95% CI 0.80-0.99)); in men and women (AUC 0.96 (95% CI 0.94-0.99) vs 0.95 (95% CI 0.89-0.99)); and in patients younger and older than 75 years old (AUC 0.98 (95% CI 0.95-0.99) vs 0.93 (95% CI 0.87-0.99)). CONCLUSIONS A simple, 1-min screening test (AL-O-A score), even administered by an untrained professional, can identify delirium in internal medicine patients.

Abstract
Rationale Delirium is common in critically ill patients and associated with deleterious outcomes. Non-pharmacologic interventions are recommended in current delirium guidelines, but their effects have not been unequivocally established. Objective To determine the effects of a multicomponent nursing intervention program on delirium in the Intensive Care Unit. Methods Stepped wedge cluster randomized controlled trial, conducted in Intensive care units of 10 centers. Adult critically ill surgical, medical or trauma patients at high risk to develop delirium were included. A multicomponent nursing intervention program focusing on modifiable risk factors was implemented as standard of care. Primary outcome was the number of delirium-free and coma-free days alive in 28 days after Intensive Care Unit admission. Measurements and main results A total of 1749 patients were included. Time spent per 8 hours shift on interventions was median [IQR] 38 [14-116] in the intervention period and median 32 [13-73] minutes in the control period (p=0.44). Patients in the intervention period had median 23 [4-27] delirium-free and coma-free days alive, compared to median 23 [5-27] days for patients in the control group (mean difference -1.21 days, 95%CI -2.84 to 0.42 days; p=0.15). Also, the number of delirium days was similar: median 2 [1-4] days (ratio of medians 0.90, 95%CI 0.75 to 1.09; p=0.27). Conclusion In this large randomized controlled trial in adult ICU patients, a limited increase was achieved of the use of nursing interventions, and no change in the number of delirium-free and coma-free days alive in 28 days could be determined.

Abstract
OBJECTIVE To determine the effectiveness of a nursing intervention for delirium prevention in critically ill patients. METHOD A quasi-experimental study was conducted with a non-equivalent control group and with evaluation before and after the intervention. 157 Patients were part of the intervention group and 134 of the control group. Patients were followed-up until they were discharged from the ICU or died. The incidence of delirium in both groups was compared. Additionally, the effect measures were adjusted for the propensity score. RESULTS The incidence and incidence rate of delirium in the control group were 20.1% and 33.1 per 1000 person-days (CI 95% 22.7 to 48.3) and in the intervention group was 0.6% and 0.64 per 1000 person-days (CI 95% 0.22 to 11.09), respectively. The crude Hazard Ratio was 0.06 (CI 95% 0,008 to 0,45) and adjusted 0.07 (CI 95% 0,009 to 0,60). The number needed to be treated was six. CONCLUSION Low incidence of delirium in critically ill patients intervened demonstrated the effectiveness of interventions. The average intervention time was 4 days with a 15-minutes dedication for each patient.

Abstract
Background Delirium is a common disorder among hospitalized older patients and results in increased morbidity and mortality. The prevention of delirium is still challenging in older patient care. The role of antipsychotics in delirium prevention has been limited. Therefore, we conducted a trial to investigate the efficacy of quetiapine use to prevent delirium in hospitalized older medical patients. Methods This study was a randomized double-blind controlled trial conducted at Ramathibodi Hospital, Bangkok, Thailand. Patients aged ≥65 years hospitalized in the internal medicine service were randomized to quetiapine 12.5 mg or placebo once daily at bedtime for a maximum 7-day duration. The primary end point was delirium incidence. Secondary end points were delirium duration, length of hospital stay, ICU admission, rehospitalization and mortality within 30 and 90 days. Results A total of 122 patients were enrolled in the study. Eight (6.6%) left the trial before receiving the first dose of the intervention, whereas 114 (93.4%) were included in an intention-to-treat analysis allocated to the quetiapine or placebo group (n = 57 each). The delirium incidence rates in the quetiapine and placebo groups were 14.0 and 8.8% (OR = 1.698, 95% CI 0.520–5.545, P = 0.381), respectively. Other endpoints in the quetiapine and placebo groups were the median length of hospital stay, 6 (4–8) days versus 5 (4–8) days (P = 0.133), respectively; delirium duration, 4 (2.3–6.5) versus 3 (1.5–4.0) days (P = 0.557), respectively; ICU admission, 3 (5.3%) patients from both groups (P = 1.000); and mortality in the quetiapine and placebo groups, 1 (1.8%) versus 2 (3.5%) at 30 days (P = 0.566) and 7 (12.3%) versus 9 (15.8%) days at 90 days (P = 0.591). There were no significant differences in other outcomes. None of the participants reported adverse events. Conclusions Quetiapine prophylaxis did not reduce delirium incidence in hospitalized older medical patients. The use of quetiapine to prevent delirium in this population group should not be recommended. Trial registration This trial was retrospectively registered with the Thai clinical trials registry (TCTR) at clinicaltrials.in.th (TCTR20190927001) on September 26, 2019.

Abstract
Background
Delirium is a distressing, common and serious condition in older people in hospital. Evidence suggests that it could be prevented in about one-third of patients using multicomponent interventions targeting delirium risk factors, but these interventions are not yet routinely available in the NHS.
Objective
The objective was to improve delirium prevention for older people admitted to the NHS.
Design
Project 1 comprised case studies employing qualitative methods (observation, interviews, workshops) in three NHS hospitals to develop the Prevention of Delirium system of care. Project 2 comprised case studies using mixed methods in five NHS hospitals to test the Prevention of Delirium implementation, feasibility and acceptability, and to modify the Prevention of Delirium system of care. Project 3 comprised a multicentre, cluster randomised, controlled, pragmatic feasibility study in eight hospitals, with embedded economic evaluation, to investigate the potential clinical effectiveness and cost-effectiveness of the Prevention of Delirium system of care, compared with standard care, among older patients admitted to hospital for emergency care. The primary objectives related to gathering information to design a definitive trial. Criteria for progression to a definitive trial were as follows: a minimum of six wards (75%) completing the Prevention of Delirium manual milestone checklist and an overall recruitment rate of at least 10% of the potential recruitment pool.
Setting
This study was set in NHS general hospitals.
Participants
In project 1, participants were staff, volunteers, and patient and carer representatives. In project 2, participants were staff, volunteers, patients and carers. In project 3, participants were older patients admitted to elderly care and orthopaedic trauma wards.
Intervention
The developed intervention (i.e. the Prevention of Delirium system of care).
Main outcome measures
For the feasibility study (project 3), the primary outcome measure was the Confusion Assessment Method. The secondary outcome measures were the Nottingham Extended Activities of Daily Living scale, the Clinical Anxiety Scale and the Geriatric Depression Scale Short Form.
Results
Project 1: understanding of delirium prevention was poor. Drawing on evidence, and working with ward teams, we developed the Prevention of Delirium system of care, which targeted 10 delirium risk factors. This multicomponent intervention incorporated systems and mechanisms to introduce and embed delirium prevention into routine ward practices. Project 2: five out of six wards implemented or partially implemented the Prevention of Delirium intervention. A prominent role for hospital volunteers was intended, but most wards were unable to recruit or sustain the numbers needed. We identified four conditions necessary to implement and deliver the Prevention of Delirium intervention: (1) commitment of senior nurse, (2) a named person to drive implementation forward, (3) dedicated time (1 day per week) of an experienced nurse to lead implementation and (4) adequate ward staffing levels. Overall, the intervention was acceptable to staff, volunteers, patients and carers, and did not increase nursing staff workload. In the light of these findings, the Prevention of Delirium system of care was modified for use in project 3. Project 3: 16 wards in eight hospitals (two wards per hospital) were recruited. Out of 4449 patients screened, 3274 (73.6%) were eligible and 713 were registered, resulting in a recruitment rate of 16.0%. Thirty-three (4.6%) participants withdrew. The screened and registered participants were similar, but some between-treatment group imbalances were noted among those registered to the trial. All eight wards allocated to the intervention group completed the Prevention of Delirium manual milestone checklist and delivered the Prevention of Delirium intervention (median time 18.6 weeks for implementation). Overall, fidelity to the intervention was assessed as being high in two wards, medium in five wards and low in one ward. Of the expected 5645 Confusion Assessment Method delirium assessments, 5065 (89.7%) were completed during the first 10 days of admission. The rates of return of the patient-reported questionnaire booklets were 98.0% at baseline, 81.8% at 30 days and 70.5% at 3 months. The return rate of the EuroQol-5 Dimensions questionnaire was 98.6% at baseline, 77.5% at 1 month and 65.3% at 3 months (94–98% fully completed). The completion rate of the resource use questionnaire was lower (48.7%). The number of people with new-onset delirium at 10 days was 24 (7.0%) in the Prevention of Delirium group and 33 (8.9%) in the control group. Multilevel logistic regression analysis showed that participants in the Prevention of Delirium group had non-significant lower odds of developing delirium (odds ratio 0.68, 95% confidence interval 0.37 to 1.26; p = 0.2225). The average cost of the Prevention of Delirium intervention was estimated as £10.98 per patient and the mean costs for the Prevention of Delirium and usual-care groups were £5332 and £4412, respectively, with negligible between-group differences in quality-adjusted life-years. There was conflicting evidence from the trial- and model-based analyses relating to the cost-effectiveness of the Prevention of Delirium intervention. Given this, and in view of issues with the data (e.g. high levels of missingness), the results from the economic evaluation are highly uncertain. The criteria for continuation to a future definitive randomised controlled trial were met. Such a trial would need to recruit 5200 patients in 26 hospital clusters (200 patients per cluster).
Conclusions
The Prevention of Delirium system of care was successfully developed, and a multicentre feasibility study showed that the intervention is capable of implementation and delivery in routine care, with acceptable intervention fidelity and preliminary estimate of effectiveness.
Limitations
A prominent role for volunteers was originally intended in the Prevention of Delirium system of care, but only three of the eight wards allocated to the trial intervention group involved volunteers.
Future work
The findings indicate that a definitive multicentre evaluation of the Prevention of Delirium system of care should be designed and conducted to obtain robust estimates of clinical effectiveness and cost-effectiveness.

ZEITSCHRIFT FUR EVIDENZ, FORTBILDUNG UND QUALITAT IM GESUNDHEITSWESEN 2021; 160:1-10. [PMID: 33461904 DOI: 10.1016/j.zefq.2020.11.007] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/15/2020] [Revised: 11/12/2020] [Accepted: 11/24/2020] [Indexed: 06/12/2023]
Abstract
BACKGROUND Delirium is a disturbance of attention and consciousness and a serious complication, especially in older hospitalized patients. For non-pharmacological delirium prevention, mainly so-called multicomponent programmes are described, which have to be adapted to the individual risk profile. The aim of this systematic review was to summarize the current status of the available evidence on non-pharmacological delirium prevention in general wards. METHOD The databases MEDLINE via Pubmed, CINAHL, EMBASE, PsycINFO and Cochrane Library were searched for the period from 1990 to November 2018; the methodological quality of the systematic reviews and meta-analyses was evaluated with AMSTAR 2. In order to reflect the broad spectrum of delirium prevention, international guidelines were included in the systematic review. RESULTS A total of 77 titles were read in full text, nine reviews and six guidelines were included in the analysis. Eight meta-analyses demonstrated that non-pharmacological multicomponent programmes for delirium prevention reduce the incidence of delirium compared to standard care (RR 0.65 to 0.73; OR 0.47 to 0.64, with varying methodological quality). The effect size was similar in the surgical (RR 0.63 to 0.71; OR 0.64) and non-surgical (RR 0.65 to 0.73; OR 0.47) general ward setting. The multicomponent programmes for delirium prevention each consisted of a different number of interventions. In addition to twelve person-related interventions, e. g. promotion of orientation, mobility, day-night rhythm, environmental adjustments and staff training programmes, were considered. CONCLUSION Non-pharmacological multicomponent programmes for the prevention of delirium in general wards effectively reduce the incidence of delirium and must be adapted to the individual risk factors of each patient.

Abstract
BACKGROUND Delirium is an important and common medical condition, particularly in hospitalized patients, that is associated with adverse outcomes. The identification, prevention, and treatment of delirium are increasingly regarded as major public health priorities. PURPOSE The aim of this study was to create a simple-to-use screening tool for delirium in hospitalized patients using clinical manifestations of delirium regularly observed by nurses. METHODS This study was conducted using data on 2,168 patients who had been admitted to the surgical ward between January 2011 and December 2014. Data were collected retrospectively from medical records. Univariate and multivariate analyses were performed, and a logistic regression model was constructed for the development of a predictive screening tool. After constructing a new screening tool for delirium, a receiver operating characteristic curve was drawn, the most appropriate cutoff value was decided, and the area under the curve was obtained. Bootstrapping was used for the internal model validation. RESULTS A screening tool for delirium (Subjective Delirium Screening Scale by Nurse) with a total score of 5 points was constructed as follows: 2 points for disorientation and 1 point each for restlessness, somnolence, and hallucination. The area under the curve for the Subjective Delirium Screening Scale by Nurse was 81.9% (95% CI [77.9%, 85.8%]), and the most appropriate cutoff value was determined to be 2 (sensitivity of 61.0% and specificity of 96.7%). Bootstrapped validation beta coefficients of the predictive factors were similar to the original cohort beta coefficients. CONCLUSIONS We created a screening tool for delirium using factors that were regularly observed and recorded by nurses. This tool is simple and practical and has adequate diagnostic accuracy.

Effects of nonpharmacological delirium-prevention interventions on critically ill patients' clinical, psychological, and family outcomes: A systematic review and meta-analysis. Aust Crit Care 2020; 34:378-387. [PMID: 33250403 DOI: 10.1016/j.aucc.2020.10.004] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2020] [Revised: 09/24/2020] [Accepted: 10/09/2020] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND Delirium is common in critically ill patients and may lead to severe complications, such as falls and injuries. Nonpharmacological interventions have been widely suggested to prevent delirium, yet the effects remain uncertain. OBJECTIVES The aim of the study was to determine the effects of nonpharmacological interventions on preventing delirium and improving critically ill patients' clinical, psychological, and family outcomes. METHODS Ten databases were searched from their inception to September 2020. Two reviewers assessed the methodological quality and extracted details of the included studies. The data were narratively or statistically pooled where appropriate. Dichotomous variables are presented as odds ratio (OR), and continuous variables are presented as mean difference (MD). The Grading of Recommendations Assessment, Development, and Evaluation criteria were used to assess the quality of evidence for each review outcome. RESULTS Thirty-four studies (10 randomised controlled trials, eight controlled clinical trials, and 16 before-and-after studies) were included in the analysis. Low-certainty evidence indicated that nonpharmacological interventions reduced delirium incidence (OR = 0.43, 95% confidence interval [CI] [0.33, 0.55]), delirium duration (MD = -1.43 days, 95% CI [-1.94, 0.92]), and length of stay in the intensive care unit (MD = -1.24 days, 95% CI [-2.05, -0.43]). Moderate-certainty evidence demonstrated no effect on mortality. Narrative synthesis further implied improvements in patients' psychological recovery (two studies, very low-certainty evidence) and families' satisfaction with care (two studies, very low-certainty evidence) through nonpharmacological interventions. As for effective intervention types, moderate-certainty evidence demonstrates that early mobilisation (OR = 0.33, 95% CI [0.24, 0.46], five studies, 859 participants, I2 = 24%), family participation (OR = 0.25, 95% CI [0.18, 0.34], four studies, 997 participants, I2 = 21%), and use of multicomponent interventions (OR = 0.48, 95% CI [0.34, 0.69], 13 studies, 3172 participants, I2 = 77%) are associated with reduced incidence of delirium. CONCLUSIONS Healthcare professionals are recommended to apply early mobilisation, family participation, or multicomponent interventions in clinical practice to prevent delirium. Further studies investigating the effects of nonpharmacological interventions on patients' psychological and family outcomes are warranted.

Abstract
TOPIC Protecting patient safety and preventing modifiable complications after acute ischemic stroke. CLINICAL RELEVANCE Stroke is a leading cause of death and disability in adults. Stroke survivors often experience a variety of deficits related to mobility, nutrition, immunity, mood, and cognition. These post-stroke complications and residual effects can adversely affect safety, placing the patient at risk for further injury. In order to develop a plan of care that protects patient safety, critical care and progressive care nurses must understand the unique needs of this patient population. PURPOSE To describe selected ischemic stroke-related physiological changes, how these changes contribute to safety risks, and methods of enhancing patient safety. CONTENT COVERED Stroke physiology and stroke-specific interventions that can enable nurses to reduce the risk of falls, dysphagia, malnutrition, dehydration, altered glucose metabolism, device-related infections, aspiration pneumonia, delirium, and depression.

Melatonin to prevent delirium in patients with advanced cancer: a double blind, parallel, randomized, controlled, feasibility trial. Palliat Care 2020; 19:163. [PMID: 33087111 PMCID: PMC7579814 DOI: 10.1186/s12904-020-00669-z] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2020] [Accepted: 10/07/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Delirium is highly problematic in palliative care (PC). Preliminary data indicate a potential role for melatonin to prevent delirium, but no randomized controlled trials (RCTs) are reported in PC. METHODS Patients aged ≥18 years, with advanced cancer, admitted to an inpatient Palliative Care Unit (PCU), having a Palliative Performance Scale rating ≥ 30%, and for whom consent was obtained, were included in the study. Patients with delirium on admission were excluded. The main study objectives were to assess the feasibility issues of conducting a double-blind RCT of exogenous melatonin to prevent delirium in PC: recruitment, retention, procedural acceptability, appropriateness of outcome measures, and preliminary efficacy and safety data. Study participants were randomized in a double-blind, parallel designed study to receive daily melatonin 3 mg or placebo orally at 21:00 over 28 days or less if incident delirium, death, discharge or withdrawal occurred earlier. Delirium was diagnosed using the Confusion Assessment Method. Efficacy endpoints in the melatonin and placebo groups were compared using time-to-event analysis: days from study entry to onset of incident delirium. RESULTS Over 16 months, 60/616 (9.7%; 95% CI: 7.5-12.4%) screened subjects were enrolled. The respective melatonin (n = 30) vs placebo (n = 30) outcomes were: incident delirium in 11/30 (36.7%; 95%CI: 19.9-56.1%) vs 10/30 (33%; 95% CI: 17.3-52.8%); early discharge (6 vs 5); withdrawal (6 vs 3); death (0 vs 1); and 7 (23%) vs 11 (37%) reached the 28-day end point. The 25th percentile time-to-event were 9 and 18 days (log rank, χ2 = 0.62, p = 0.43) in melatonin and placebo groups, respectively. No serious trial medication-related adverse effects occurred and the core study procedures were acceptable. Compared to those who remained delirium-free during their study participation, those who developed delirium (n = 21) had poorer functional (p = 0.036) and cognitive performance (p = 0.013), and in particular, poorer attentional capacity (p = 0.003) at study entry. CONCLUSIONS A larger double-blind RCT is feasible, but both subject accrual and withdrawal rates signal a need for multisite collaboration. The apparent trend for shorter time to incident delirium in the melatonin group bodes for careful monitoring in a larger trial.

Abstract
AIM To understand how family caregivers of older adults hospitalized for orthopaedic surgery are integrated by nurses in delirium prevention care. DESIGN Multiple case study. METHODS The sample consisted of eight cases. Each case comprised an older adult, a family caregiver, and a nurse. Data were collected from September 2017 - April 2018 through various instruments, including semi-structured interviews and family caregiver logs. Within- and across-case analyses were conducted, based on the model of The Care Partner Engagement developed by Hill, Yevchak, Gilmore-Bykovskyi, & Kolanowski (Geriatric Nursing, 35, 2014, 272). RESULTS Two themes emerged: (a) family caregivers were engaged in caring for the older adults during their hospital stay, though they had differences in terms of views and needs; and (b) family caregivers communicated with nurses but nurses did not recognize their role and did not integrate them much in care. CONCLUSION The presence and availability of family caregivers, their sense of responsibility towards the hospitalized older adults, and their positive effects on them suggest that family caregivers could be integrated more systematically in a care partnership with nurses. Poor integration of family caregivers in delirium prevention care shows that nurse delirium prevention competencies and their relational skills for communicating effectively with family caregivers need to be developed further. IMPACT Integrating family caregivers in delirium prevention care for older adults is a challenge for nurses. Family caregivers are engaged during the hospitalization of older adults, though differences and problems exist between the two groups. While there is communication between patients, family caregivers, and nurses, nurses do not recognize the role of family caregivers and hardly integrated them in the delirium prevention care of hospitalized older adults. Nurses must adopt a patient- and family-centred approach. Care and training facilities must make resources available to implement this approach in nursing practice.

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

Abstract
BACKGROUND/OBJECTIVES Detecting delirium is important to identify patients with a high risk of poor outcomes. Although many different kinds of screening instruments for delirium exist, there is no solid consensus about which methods are the most effective. In addition, it is important to find the most useful tools in predicting outcomes such as mortality. DESIGN Retrospective cohort study. SETTING University of Iowa Hospitals and Clinics. PARTICIPANTS A total of 1,125 adult inpatients (mean age = 67.7; median age = 69). MEASUREMENTS Post hoc analyses were performed based on existing data from the Confusion Assessment Method for Intensive Care Unit (CAM-ICU), Delirium Rating Scale-Revised-98 (DRS), and the Delirium Observation Screening Scale (DOSS). Correlation among these scales and relationships between 365-day mortality and each scale were evaluated. RESULTS A positive result on the CAM-ICU ("CAM-ICU positive") was associated with higher DRS and DOSS scores. A DRS score = 9/10 was the best cutoff to detect CAM-ICU positive, and DOSS = 2/3 was the best cutoff to detect CAM-ICU positive. CAM-ICU positive was associated with high 365-day mortality. DRS score = 9/10 and DOSS score = 0/1 were found to differentiate mortality risk the most significantly. Higher DRS and DOSS scores significantly coincided with a decrease in a patient's survival rate at 365 days. CONCLUSION The best DRS and DOSS cutoff scores to differentiate 365-day mortality risk were lower than those commonly used to detect delirium in the literature. New cutoff scores for the DRS and DOSS might be useful in differentiating risk of mortality among hospital patients.

Non-pharmacological interventions to reduce the incidence and duration of delirium in critically ill patients: A systematic review and network meta-analysis. J Crit Care 2020; 60:241-248.

Abstract
OBJECTIVE To compare non-pharmacological interventions in their ability to prevent delirium in critically ill patients, and find the optimal regimen for treatment. METHODS Literature searches were conducted using PubMed, Embase, CINAHL, and Cochrane Library databases until the end of June 2019. We estimated the risk ratios (RRs) for the incidence of delirium and in-hospital mortality and found the mean difference (MD) for delirium duration and the length of ICU stay. The probabilities of interventions were ranked based on clinical outcomes. The study was registered on PROSPERO (CRD42020160757). RESULTS Twenty-six eligible studies were included in the network meta-analysis. Studies were grouped into seven intervention types: physical environment intervention (PEI), sedation reducing (SR), family participation (FP), exercise program (EP), cerebral hemodynamics improving (CHI), multi-component studies (MLT) and usual care (UC). In term of reducing the incidence of delirium, the two most effective interventions were FP (risk ratio (RR) 0.19, 95% confidence interval (CI) 0.08 to 0.44; surface under the cumulative ranking curve (SUCRA) = 94%) and MLT (RR 0.43, 95% CI 0.30 to 0.57; SUCRA = 68%) compared with observation. Although all interventions demonstrated nonsignificant efficacy in regards to delirium duration and the length of the patient's stay in the ICU, MLT (SUCRA = 78.6% and 71.2%, respectively) was found to be the most effective intervention strategy. In addition, EP (SUCRA = 97.2%) facilitated a significant reduction in hospital mortality, followed in efficacy by MLT (SUCRA = 73.2%), CHI (SUCRA = 35.8%), PEI (SUCRA = 34.8%), and SR (SUCRA = 31.8%). CONCLUSIONS Multi-component strategies are overall the optimal intervention techniques for preventing delirium and reducing ICU length of stay in critically ill patients by way of utilizing several interventions simultaneously. Additionally, family participation as a method of patient-centered care resulted in better outcomes for reducing the incidence of delirium.

Abstract
The incidence of delirium in intensive care units is high and associated with poor outcomes; therefore, its prediction is desirable to establish preventive treatments. This retrospective study proposes a novel approach for delirium prediction. We analyzed static and temporal data from 10,475 patients admitted to one of 15 intensive care units (ICUs) in Alberta, Canada between January 1, 2014 and June 30, 2016. We tested 168 different combinations of study design parameters and five different predictive models (logistic regression, support vector machines, random forests, adaptive boosting and neural networks). The area under the receiver operating characteristic curve (AUROC) ranged from 0.754 (CI 95% ± 0.018) to 0.852 (± 0.033), with sensitivity and specificity respectively ranging from 0.739 (CI 95% ± 0.047) to 0.840 (CI 95% ± 0.064), and 0.770 (CI 95% ± 0.030) to 0.865 (CI 95% ± 0.038). These results are similar to previous studies; however, our approach allows for continuous updates and short-term prediction horizons which might provide major advantages.

Abstract
Objective to provide a preliminary estimate of the effectiveness of the prevention of delirium (POD) system of care in reducing incident delirium in acute hospital wards and gather data for a future definitive randomised controlled trial. Design cluster randomised and controlled feasibility trial. Setting sixteen acute care of older people and orthopaedic trauma wards in eight hospitals in England and Wales. Participants patients 65 years and over admitted to participating wards during the trial period. Interventions participating wards were randomly assigned to either the POD programme or usual care, determined by existing local policies and practices. The POD programme is a manualised multicomponent delirium prevention intervention that targets 10 risk factors for delirium. The intervention wards underwent a 6-month implementation period before trial recruitment commenced. Main outcome measure incidence of new-onset delirium measured using the Confusion Assessment Method (CAM) measured daily for up to 10 days post consent. Results out of 4449, 3274 patients admitted to the wards were eligible. In total, 714 patients consented (713 registered) to the trial, thirty-three participants (4.6%) withdrew. Adherence to the intervention was classified as at least medium for seven wards. Rates of new-onset delirium were lower than expected and did not differ between groups (24 (7.0%) of participants in the intervention group versus 33 (8.9%) in the control group; odds ratio (95% confidence interval) 0.68 (0.37–1.26); P = 0.2225). Conclusions based on these findings, a definitive trial is achievable and would need to recruit 5220 patients in 26 two-ward hospital clusters. Trial registration: ISRCTN01187372. Registered 13 March 2014.

Abstract
BACKGROUND delirium is a frequent complication of hospital admission for older people and can be reduced by multicomponent interventions, but implementation and delivery of such interventions is challenging. OBJECTIVE to investigate fidelity to the prevention of delirium system of care within a multicentre, pragmatic, cluster randomised, controlled feasibility trial. SETTING five care of older people and three orthopaedic trauma wards in eight hospitals in England and Wales. DATA COLLECTION research nurse observations of ward practice; case note reviews and examination of documentation. ASSESSMENT 10 health care professionals with experience in older people's care assessed the fidelity to 21 essential implementation components within four domains: intervention installation (five items; maximum score = 5); intervention delivery (12 items; maximum score = 48); intervention coverage (three items; maximum score = 16); and duration of delivery (one item; maximum score = 1). RESULTS the mean score (range) for each domain was: installation 4.5 (3.5-5); delivery 32.6 (range 27.3-38.3); coverage 7.9 (range 4.2-10.1); and duration 0.38 (0-1). Of the 10 delirium risk factors, infection, nutrition, hypoxia and pain were the most and cognitive impairment, sensory impairment and multiple medications the least consistently addressed. Overall fidelity to the intervention was assessed as high (≥80%) in two wards, medium (51-79%) in five wards and low (≤50%) in one ward. CONCLUSION the trial was designed as a pragmatic evaluation, and the findings of medium intervention fidelity are likely to be generalisable to delirium prevention in routine care and provide an important context to interpret the trial outcomes.
