A call to action for delirium research: Meta-analysis and regression of delirium associated mortality

BackgroundDelirium is an extremely common hospital complication. No study to date has assessed whether a priori defined covariates; type of hospital setting and year of study publication, influence the relationship between delirium and mortality. This is also the first study to examine the longitudinal trend of delirium-associated mortality over recent decades, to analyse the trajectory of our efforts in combating this disease.MethodsMEDLINE, EMBASE and PsycINFO, were searched from January 1981 to May 2018 for English-language primary articles. Rigorous title and abstract screen and full-text screen were conducted independently by two reviewers. This paper adhered to MOOSE guidelines. Data was extracted independently by one reviewer using standardised data-collection sheets, with a separate reviewer verifying for accuracy. The quality of included studies was assessed using the Newcastle-Ottawa Quality Assessment Scale. Unadjusted effect sizes and event counts were analysed with a random effects model in primary meta-analysis and meta-regression, whereas a mixed effect model was used in secondary sub-group analysis. Mortality data at longest follow-up and cumulative mortality (hospital mortality combined with mortality at longest follow-up) data were analysed.ResultsAs part of a larger project, 446 of 6790 articles were retrieved, including 71 studies that measured mortality. Our results demonstrate that elderly inpatients with delirium had significantly greater odds of mortality (OR 3.18 [95%CI: 2.73, 3.70]) compared to non-delirious controls. Patients with delirium in the ICU had the highest odds for mortality (OR: 7.09 [95%CI: 3.60, 14.0]); double the risk compared to the average. Curiously, despite advancements in delirium research, delirium associated in-hospital odds of mortality has not changed in 30 years.ConclusionThis is the largest meta-analysis to confirm the association between delirium and mortality, in older (age ≥ 65) hospital inpatients.The current meta-analysis highlights the significant odds of mortality after an episode of delirium, and these odds are much higher for ICU patients. However, in contrast to other medical conditions that have seen a decrease in associated mortality over the past few decades, delirium associated mortality remains unchanged. These findings underscore the urgent need for better delirium treatments.PROSPERO Registration Number: CRD42018098627, https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=98627

Antipsychotic Drugs in Prevention of Postoperative Delirium-What Is Known in 2020?

Delirium is one of the most frequently reported neuropsychiatric complications in the perioperative period, especially in the population of elderly patients who often suffer from numerous comorbidities undergoing extensive or urgent surgery. It can affect up to 80% of patients who require hospitalization in an intensive care setting postoperatively. Delirium increases mortality, morbidity, length of hospital stay, and cost of treatment. An episode of delirium in the acute phase may lower the general quality of life and increases the risk of cognitive decline long-term. Since pharmacological treatment of delirium is not highly effective, focus of research has shifted towards developing preventive strategies. We aimed to perform a review of the topic based on the most recent literature. We conclude that, based on the available data, it seems impossible to make strong recommendations for using antipsychotic drugs in prophylaxis. Further research should answer the question what, if any, benefit patients receive from the pharmacological prevention of delirium, and which agents should be used.

Delirium Detection Based on the Clinical Experience of Pediatric Intensivists

To estimate the frequency of delirium detected by pediatric intensivists, based only on their clinical experience, without a valid and reliable tool. Multicenter, prospective, descriptive, observational study. Three PICUs in Rio de Janeiro, Brazil. Twenty-nine days to 18 years old. Electronic forms were sent weekly to the pediatric intensivists responsible for the daily care of patients from March to September 2015, to fill in information about the presence of risk factors and diagnosis of delirium in all patients who remained in the PICU in the last week. Demographics and other clinical data were extracted from an electronic system. A total of 504 admissions in the three PICUs (477 patients) were included. The pediatric intensivists reported only two episodes of delirium in two different patients, based on insufficient criteria. Considering all PICUs admissions, the reported frequency of delirium was only 0.4% (2/504). The low frequency of delirium detection and the insufficient criteria used for the diagnosis in these units suggest flaws in the recognition of delirium and probably the occurrence of underdiagnosis/misdiagnosis when it is based only on clinical experience, without the use of a valid and reliable tool.

Delirium Post-Stroke: Short- and Long-Term Effect on Depression, Anxiety, Apathy and Aggression (Research Study-Part of PROPOLIS Study).

Background: Stroke patients are particularly vulnerable to delirium episodes, but very little is known about its subsequent adverse mental health outcomes. The author’s objective was to explore the association between in-hospital delirium and depression, anxiety, anger and apathy after stroke. Methods: A total of 750 consecutive patients with acute stroke or transient ischemic attack, were screened for delirium during hospitalization. Patients underwent mental health evaluation in hospital, 3 and 12 months post-stroke; depression, apathy, anxiety and anger were the outcomes measured at all evaluation check points. Results: Delirium was an independent risk factor for depression (OR = 2.28, 95%CI 1.15–4.51, p = 0.017) and aggression (OR = 3.39, 95%CI 1.48–7.73, p = 0.004) at the hospital, for anxiety 3 months post-stroke (OR = 2.83, 95%CI 1.25–6.39, p = 0.012), and for apathy at the hospital (OR = 4.82, 95%CI 2.25–10.47, p < 0.001), after 3 (OR = 3.84, 95%CI 1.31–11.21, p = 0.014) and 12 months (OR = 4.95, 95%CI 1.68–14.54, p = 0.004) post stroke. Conclusions: The results of this study confirm, that mental health problems are very frequent complications of stroke. Delirium in the acute phase of stroke influences mental health of patients. This effect is especially significant in the first months post-stroke and vanishes with time, which suggests that in-hospital delirium might not be a damaging occurrence in most measures of mental health problems from a long-term perspective.

Association of Delirium With Long-term Cognitive Decline

Delirium is associated with increased hospital costs, health care complications, and increased mortality. Long-term consequences of delirium on cognition have not been synthesized and quantified via meta-analysis. To determine if an episode of delirium was an independent risk factor for long-term cognitive decline, and if it was, whether it was causative or an epiphenomenon in already compromised individuals. A systematic search in PubMed, Cochrane, and Embase was conducted from January 1, 1965, to December 31, 2018. A systematic review guided by Preferred Reporting Items for Systematic Reviews and Meta-analyses was conducted. Search terms included delirium AND postoperative cognitive dysfunction; delirium and cognitive decline; delirium AND dementia; and delirium AND memory. Inclusion criteria for studies included contrast between groups with delirium and without delirium; an objective continuous or binary measure of cognitive outcome; a final time point of 3 or more months after the delirium episode. The electronic search was conducted according to established methodologies and was executed on October 17, 2018. Three authors extracted data on individual characteristics, study design, and outcome, followed by a second independent check on outcome measures. Effect sizes were calculated as Hedges g. If necessary, binary outcomes were also converted to g. Only a single effect size was calculated for each study. The planned main outcome was magnitude of cognitive decline in Hedges g effect size in delirium groups when contrasted with groups that did not experience delirium. Of 1583 articles, data subjected from the 24 studies (including 3562 patients who experienced delirium and 6987 controls who did not) were included in a random-effects meta-analysis for pooled effect estimates and random-effects meta-regressions to identify sources of study variance. One study was excluded as an outlier. There was a significant association between delirium and long-term cognitive decline, as the estimated effect size (Hedges g) for 23 studies was 0.45 (95% CI, 0.34-0.57; P < .001). In all studies, the group that experienced delirium had worse cognition at the final time point. The I2 measure of between-study variability in g was 0.81. A multivariable meta-regression suggested that duration of follow-up (longer with larger gs), number of covariates controlled (greater numbers were associated with smaller gs), and baseline cognitive matching (matching was associated with larger gs) were significant sources of variance. More specialized subgroup and meta-regressions were consistent with predictions that suggested that delirium may be a causative factor in cognitive decline. In this meta-analysis, delirium was significantly associated with long-term cognitive decline in both surgical and nonsurgical patients.

State of the science in pediatric ICU delirium: An integrative review.

Delirium is a complication of critical illness associated with poor outcomes. Although widely studied in adults, comparatively little is understood about delirium in pediatric intensive care units (ICUs). The purpose of this integrative review is to determine the extent and nature of current evidence, identify gaps in the literature, and outline future areas for investigation of pediatric ICU delirium. Eligible articles included research reports of delirium in pediatric ICU samples published in English since 2009. After an extensive literature search and consideration for inclusion/exclusion criteria, 22 articles were chosen for review. Delirium was highly prevalent in the ICU. Delirium episodes developed early in hospitalization, lasted several days, and consisted of hypoactive or mixed motor subtypes. Frequently identified independent risk factors included young age, developmental delay, mechanical ventilation, and benzodiazepine exposure. Pediatric delirium was independently associated with increased length of stay, costs, and mortality. The long-term cognitive, psychological, and functional morbidities associated with pediatric delirium remain largely unknown. Few researchers have implemented interventions to prevent or manage delirium. There was little evidence for the efficacy or safety of pharmacological management. Multicomponent delirium bundles may significantly decrease delirium incidence. Key quality issues among studies included variation in delirium screening, low levels of evidence (i.e., observational studies), and limited ability to determine intervention efficacy in quasi-experimental designs. Although the quantity and quality of pediatric delirium research has rapidly increased, further studies are needed to understand the long-term effects of pediatric delirium and determine the efficacy and safety of interventions for prevention and management.

Impact of Early Reinitiation of Neuropsychiatric Medications on Agitation and Delirium in the Intensive Care Unit: A Retrospective Study.

Approximately 17% of intensive care unit (ICU) patients are prescribed at least 1 home neuropsychiatric medication (NPM). When abruptly discontinued, withdrawal symptoms may occur manifesting as agitation or delirium in the ICU setting. To evaluate the impact of early reinitiation of NPMs. This was a retrospective, observational cohort of adult ICU patients in a tertiary care hospital. Patients were included if admitted to the ICU and prescribed a NPM prior to arrival. Study groups were based on the timing of reinitiation of at least 50% of NPMs: ≤72 hours (early group) versus >72 hours (late group). The primary outcome was the proportion of patients with at least 1 agitation or delirium episode in the first 72 hours. Agitation and delirium were defined as at least 1 RASS assessment between +2 to +4 and a positive CAM-ICU assessment, respectively. A total of 300 patients were included, with 187 (62%) and 113 (38%) in the early and late groups, respectively. There was no difference in agitation or delirium (late 54 [48%] vs early 62 [33%]; adjusted odds ratio [aOR] = 1.5; 95% CI = 0.8-2.8; P = 0.193). Independent risk factors found to be associated with the primary outcome were restraints (aOR = 12.9; 95% CI = 6.9-24.0; P < 0.001) and benzodiazepines (BZDs; aOR = 2.0; 95% CI = 1.0-3.7; P = 0.038). After adjustment for baseline differences, there was no difference in agitation or delirium. Independent risk factors were restraint use and newly initiated BZDs.

Post-stroke delirium risk factors, signs and symptoms of onset and outcomes as perceived by expert nurses: A focus group study

BackgroundHigher rates of delirium have been reported among patients with acute stroke. However, poorly modifiable risk factors have been documented to date while sign and symptoms capable of early detecting its onset and outcomes in this specific population have been largely neglected. The aim of this study was to emerge nurses’ clinical knowledge and experiences regarding post-stroke delirium (a) risk factors, (b) signs and symptoms of delirium onset, and (c) outcomes. MethodA qualitative study based upon focus groups have been performed on 2019 and here reported according to the COnsolidated criteria for REporting Qualitative research. A purposeful sample of 28 nurses was invited to participate in focus groups at two Italian hospitals, and 20 participated. A semi-structured question guide was developed; all focus groups were audio recorded and then transcribed verbatim. Two researchers independently analysed, coded and categorised the findings according to the main research question. A member checking with ten nurses was also performed to ensure rigour. ResultsFour risk factors emerged (a) at the individual level; (b) associated with previous (e.g., dementia) and the current clinical condition (stroke), (c) associated with the nursing care delivered, and (d) associated with the hospital environment. In their daily practice, nurses suspect the onset of delirium when some motor, verbal or multidimensional signs and symptoms occur. The delirium episodes affect outcomes at the individual, family, and at the system levels. ConclusionsIn a field of research in need of study, we have involved expert nurses who shared their tacit knowledge to gain insights regarding risk factors, early signs and symptoms of delirium and its outcomes to address future directions of this research field.

Relationship Between Pain, Opioid Treatment, and Delirium in Older Emergency Department Patients.

Emergency department (ED) stay and its associated conditions (immobility, inadequate hydration and nutrition, lack of stimulation) increase the risk of delirium in older patients. Poorly controlled pain and paradoxically opioid pain treatment have also been identified as triggers for delirium. The aim of this study was to assess the relationship between pain, opioid treatment, and delirium in older ED patients. A multicenter prospective cohort study was conducted in four hospitals across the province of Québec (Canada). Patients aged≥65years old, waiting for hospital admission between Marchand July2015, who were nondelirious upon ED arrival, who were independent or semi-independent in their daily living activities, and who had an ED stay of at least 8hours were included. Delirium assessments were conducted twice a day during the patient's entire ED stay and their first 24hours on the hospital ward using the Confusion Assessment Method. Pain intensity was evaluated using a visual analog scale (VAS= 0-100) during the initial interview, and all opioid treatments were documented. A total of 338 patients were included; 51% were female, and mean(±SD) age was 77(±8)years. Forty-one patients (12%) experienced delirium during their hospital stay occurring within a mean (±SD) delay of 47(±19)hours after ED admission. Among patients with pain intensity≥65 from VAS (0-100), 26% experienced delirium compared to 11% for patients with pain<65 (p<0.01), and no significant association was found between opioid consumption and delirium (p=0.31). Logistic regression controlling for confounding factors showed that patients with pain intensity≥65 are 3.3 (95% confidence interval= 1.4 to 7.9) times more likely to develop delirium than patients who had painintensity of <65. Severe pain, not opioids, is associated with the development of delirium during ED stay. Adequate pain control during the hospital stay may contribute to a decrease in delirium episodes.

1159 Sleep Traits And Incident Delirium During A Decade Of Follow-up In 173,000 Participants

Abstract Introduction Delirium is an acute decline in attention and cognition that is with associated long-term cognitive dysfunction in elderly patients. Accumulating evidence points to strong associations between sleep health and disorders of the brain. We tested whether baseline sleep duration, chronotype, daytime dozing, insomnia or sleep apnea predict incident delirium during hospitalization. Methods We studied participants from the UK Biobank who have been followed for up to 10 years until 2017. We included 173,221 participants (mean age 60±5; range 50-71 at baseline) who had at least one episode of hospitalization/surgery and were free from prior episodes of delirium. Delirium diagnosis, hospitalization and surgical events were derived using ICD-10 coding. Multivariate logistic regression models were performed to examine the associations of self-reported baseline sleep duration (&amp;lt;6hrs/6-9h/&amp;gt;9h), daytime dozing (often/rarely), insomnia (often/rarely) and presence of sleep apnea (ICD-10 and self-report) with incident delirium during follow-up. Models were adjusted for demographics, education, Townsend deprivation index, and major confounders (number of hospitalizations/surgical procedures, BMI, diabetes, major cardiovascular diseases and risk factors, major neurological diseases, major respiratory diseases, cancer, alcohol, depression/anxiety, sedatives/sleep aides, antipsychotics, steroids and opioids). Results In total, 1,023 (5.7 per 1,000 subjects) developed delirium. A prior diagnosis of sleep apnea (n=1,294) saw almost a two-fold increased odds (OR 1.96, 95% CI: 1.30-2.30 p=0.001) while those who often had daytime dozing were also at increased risk (OR 1.35, 95% CI: 1.02-1.80, p=0.025). Both these effects were independent of each other. No independent effects on incident delirium were observed from sleep duration, insomnia, or chronotype. Conclusion Certain sleep disturbances, in particular sleep apnea and daytime dozing, are independently associated with an increased risk for developing delirium. Further work is warranted to examine underlying mechanisms and to test whether optimizing sleep health can reduce the risk of developing delirium.

Assessment of delirium in children admitted into the Intensive Care Unit: psCAM-ICU Tool

Background: Delirium has been identified as a risk factor for the mortality of critically ill patients, generating great social and economic impacts, since patients require more days of mechanical ventilation and a prolonged hospital stay in the intensive care unit (ICU), thus increasing medical costs. Objective: To describe the prevalence and characteristics of delirium episodes in a sample of 6-month to 5-year-old children who are critically ill. Methods: Cohort study at a Pediatric Intensive Care Unit (PICU) in Bogotá (Colombia). Participants were assessed by the Preschool Confusion Assessment Method for the ICU (psCAM-ICU) within the first twenty-four hours of hospitalization. Results: One quarter of the participants (25.8%) presented some type of delirium. Among them, two sub-types of delirium were observed: 62.5% of the cases were hypoactive and 37.5% hyperactive. Moreover, from them, six were male (75%) and 2 female (25%). Primary diagnosis was respiratory tract infection in 62.55% of the patients, while respiratory failure was diagnosed in the remaining 37.5%. Conclusions: The implementation of delirium monitoring tools in critically ill children provides a better understanding of the clinical manifestation of this phenomenon and associated risk factors in order to contribute to the design of efficient intervention strategies.

Delirium in intensive care: A stepped-wedge cluster randomised controlled trial for a nurse-led intervention to reduce the incidence and duration of delirium among adults admitted to the intensive care unit (protocol)

BackgroundDelirium is an acute disorder of attention and cognition with the highest rates among adults receiving intensive care. An acute episode of delirium is associated with morbidity and mortality, as well as a significant psychological sequela. Importantly, an increasing body of evidence supports the benefit of nonpharmacological, nurse-led interventions to reduce the incidence and duration of delirium among adults cared for in the intensive care unit (ICU). ObjectivesThis study will evaluate the impact of a nursing-led delirium prevention protocol that is aimed at reducing the incidence and duration of delirium among adults admitted to the ICU. The delirium prevention nursing protocol specifically targets risk factors for delirium. Study planA stepped-wedge cluster randomised controlled trial approach will be used to assess the effectiveness of the nurse-led intervention, in four adult ICUs across the South Western Sydney Local Health District (SWS-LHD), over a 12-month period. The primary outcomes of interest are (i) the incidence of delirium before and after the implementation of the nurse-led intervention and (ii) the number of delirium-free days during an ICU stay, before and after the implementation of the nurse-led intervention.

Intra-operative hyperoxia and the risk of delirium in elderly patients after cardiac surgery.

Delirium is a common complication after cardiac surgery. The aim of our study was to determine the impact of hyperoxia episodes occurring during cardiopulmonary bypass (CBP) on the rate of delirium episodes in the postoperative period. 93 patients, aged ≥ 65, who underwent elective cardiac surgery (CBP <90 minutes) were enrolled. The occurrence of delirium episodes was examined every 12 hours for three days after surgery. Eleven patients (11.8%) developed postoperative delirium (POD (+)) and 83 did not (POD (-)). More incidences of severe hyperoxia (PaO2 ≥ 26.6kPa) during CBP were observed in the POD (+) group: 64% had ≥ 2 episodes of hyperoxia, 27% ≥ 3, and 18% ≥ 4, while in the POD (-) group: 42%, 13% and 1%, respectively (P=0.02). Patients in the POD (+) group had a higher maximum PaO2 during CBP than the POD (-) group (37 ± 5.8 vs 31.6 ± 6.6 kPa; P=0.01) and a higher mean PaO2 (30.1 ± 4.5 vs 26.1 ± 5.6 kPa; P=0.01). The optimal maximum PaO2 cut-off point for the occurrence of delirium was 33.2 kPa (AUC 0.72, P=0.001, sensitivity 75%, specificity 38%). We conclude that CBP hyperoxia episodes may be a risk factor associated with the occurrence of postoperative delirium.

Delirium Reduced With Intravenous Acetaminophen in Geriatric Hip Fracture Patients.

Postoperative delirium is associated with opioid use in the elderly and is a common complication of geriatric hip fractures, with reported incidences from 16% to 70%. Intravenous (IV) acetaminophen is a safe and efficacious medication in elderly patients and has been shown to reduce use of opioids after hip fracture. At our institution, IV acetaminophen was implemented for the first 24 hours postoperatively as part of a multimodal pain control regimen for geriatric hip fracture patients. A retrospective review of 123 hip fragility fracture patients older than 60 years from January 2016 to December 2016 was performed. Delirium was identified using a validated chart-based review tool. The rate of delirium, as well as length of stay, pain scores, opioid administration, need for one-to-one supervision, and readmissions were analyzed. Sixty-five patients (52.8%) received IV acetaminophen during this period. No notable differences were found in baseline characteristics between groups. Ten of 65 patients receiving IV acetaminophen postoperatively experienced delirium compared with 19 of 58 who did not receive the medication (15.4% versus 32.8%, P = 0.024). The IV acetaminophen group also required fewer doses of IV opioids on postoperative day 1 (0.37 versus 1.19 doses, P = 0.008), were less likely to require one-to-one supervision (9.2% versus 24.1%, P = 0.025), and had shorter lengths of hospital stay (6.37 versus 8.47 days, P = 0.037). Readmission rates and discharge dispositions did not vary with significance between the two groups. The inclusion of IV acetaminophen as part of a multimodal pain regimen led to fewer episodes of delirium in this study. The reduced use of opioids immediately after surgery may have been a large factor in this outcome. Lower delirium rates may reduce the utilization of inpatient resources for direct patient supervision and provide for shorter hospital stays.

DEPRESSIVE SYMPTOM SEVERITY AMONG FAMILY MEMBERS OF OLDER ADULTS WITH HETEROGENEOUS COGNITIVE VULNERABILITY

Introduction Cognitive vulnerability among community-dwelling older adults (age > 65) refers to living with cognitive impairment due to dementia, experiencing delirium which is associated with longer-term cognitive impairment, and/or living with depression which is a known risk factor for cognitive impairment. Family members of older adults with dementia often report considerable levels of depressive symptoms, and many interventions for these family members aim to reduce their depressive symptoms. However, much less is known about depressive symptoms among family members of older adults with depression or recent episodes of delirium. Therefore, in this study we compared levels of depressive symptoms among family members of older adults based on type and severity of older adults’ cognitive vulnerability. Methods This study utilized baseline data from an ongoing randomized clinical trial testing the efficacy of an in-home multidisciplinary team care management intervention for older adults with cognitive vulnerability. During eligibility assessment, older adults are determined to have dementia based on score of 16 on the Center for Epidemiologic Studies Depression (CESD) Scale, and recent delirium based on the informant version of the Confusion Assessment Method (FAM CAM). Family members of older adults are required to join the clinical trial if older adults have dementia or recent delirium, and they are invited to join if older adults have depression without dementia or delirium. Baseline data are collected during in-person, in-home interviews conducted separately with older adults and with family members; this study includes baseline data from the first 259 dyads enrolled in the trial. We measured older adults’ cognitive vulnerability in 3 ways: (1): whether their eligibility determination was dementia, depression, and/or delirium; groups sizes were dementia only (n=76); depression only (n=70); depression and dementia (n=56); and delirium plus depression and/or dementia (n=57); (2) cognitive impairment severity based on TICS score; and (3) depressive symptom severity based on CESD score. Family member depression severity was measured based on their CESD score. In 3 separate multivariate regression models, family caregiver depression severity was regressed on each of the three measures of cognitive vulnerability; covariates in all models included family member sex, familial relationship of family member to older adults, and number of hours per week the family member reported caring for the older adult. Results Among older adults, 57% were female, mean/sd age=77/6.9, and 91% were White; among family members, 63% were female, mean/sd age=66/13.8, 90% were White, 54% spouses, 24% daughters, 9% sons, the remainder other family members. Controlling for covariates, we found that family member depressive symptom severity was: (1) least severe if older adults had dementia only (CESD adjusted mean=5.6) and most severe if older adults had depression only (CESD adjusted mean score=9.8) (b=4.2; p Conclusions Family members of older adults report greater depressive symptoms when their older relatives also have depression compared to when their older relatives have dementia, even after accounting for familial relationship and how much care family members provide to their older relatives. We conclude that family members of older adults with depression deserve greater clinical and research attention to address their own depressive symptoms.

Benzodiazepines for treatment of patients with delirium excluding those who are cared for in an intensive care unit.

Delirium is a very common condition associated with significant morbidity, mortality, and costs. Current critical care guidelines recommend first and foremost the use of nonpharmacological strategies in both the prevention and treatment of delirium. Pharmacological interventions may augment these approaches and they are currently used widely in clinical practice to manage the symptoms of delirium. Benzodiazepines are currently used in clinical practice to treat behavioural disturbances associated with delirium but current guidelines do not recommend their use for this indication. The use of these medicines is controversial because there is uncertainty about whether they are effective for patients or have the potential to harm them. To assess the effectiveness and safety of benzodiazepines in the treatment of delirium (excluding delirium related to withdrawal from alcohol or benzodiazepines) in any healthcare settings other than intensive care units (ICU). We searched ALOIS: the Cochrane Dementia and Cognitive Improvement Group's Specialized Register up to 10 April 2019. ALOIS contains records of clinical trials identified from monthly searches of a number of major healthcare databases (including MEDLINE, Embase, PsycINFO, CINAHL, LILACS), numerous trial registries (including national, international and pharmaceutical registries), and grey literature sources. We included randomised controlled trials (RCTs) conducted in healthcare settings that ranged from nursing homes and long-term care facilities to any hospital setting except for ICUs, involving adult patients with delirium excluding those with delirium related to alcohol or benzodiazepine withdrawal. Included RCTs had to assess the effect of benzodiazepines, at any dose and given by any route, compared with placebo or another drug intended to treat delirium. Two review authors independently assessed study eligibility, extracted data, and assessed the risk of bias of included studies. We decided whether or not to pool data on the basis of clinical heterogeneity between studies. We used GRADE (Grades of Recommendation, Assessment, Development and Evaluation) methods to assess the quality of evidence. We identified only two trials that satisfied the selection criteria. We did not pool the data because of the substantial clinical differences between the trials. In one trial, participants (n = 58) were patients in an acute palliative care unit with advanced cancer who had a mean age of 64 years. All of the participants had delirium, were treated with haloperidol, and were randomised to receive either lorazepam or placebo in combination with it. Due to very serious imprecision, all evidence was of low certainty. We were unable to determine whether there were clinically important differences in the severity of delirium (mean difference (MD) 2.10, 95% CI -0.96 to 5.16; n = 50), length of hospital admission (MD 0.00, 95% CI -3.45 to 3.45; n = 58), mortality from all causes (risk ratio (RR) 0.33, 95% CI 0.04 to 3.02; participants = 58) or any of a number of adverse events. Important effects could not be confirmed or excluded. The study authors did not report the length of the delirium episode. In the other trial, participants (n = 30) were patients in general medical wards with acquired immune deficiency syndrome (AIDS) who had a mean age of 39.2 years. Investigators compared three drug treatments: all participants had delirium, and were randomised to receive lorazepam, chlorpromazine, or haloperidol. Very low-certainty evidence was identified, and we could not determine whether lorazepam differed from either of the other treatments in the effect on severity of delirium, any adverse event, or mortality from all causes. The study authors did not report the length of the delirium episode or the length of hospital admission. There is no enough evidence to determine whether benzodiazepines are effective when used to treat patients with delirium who are cared for in non-ICU settings. The available evidence does not support their routine use for this indication. Because of the scarcity of data from randomised controlled trials, further research is required to determine whether or not there is a role for benzodiazepines in the treatment of delirium in non-ICU settings.

Prospective Evaluation of Delirium in Geriatric Patients Undergoing Emergency General Surgery

The prevalence of delirium and its impact on outcomes after emergency general surgery (EGS) remain unexplored. The aims of our study were to assess the impact of frailty on delirium and the impact of delirium on outcomes in geriatric EGS patients. We performed a 1-year (2017) prospective cohort analysis of all geriatric (age ≥ 65 years) patients who underwent EGS. Frailty was calculated using the Emergency General Surgery-Specific Frailty Index (ESFI). Delirium was assessed using the Confusion Assessment Method (CAM). Patients were dichotomized as delirious or non-delirious. We performed regression analysis controlling for demographics, admission vitals, American Society of Anesthesiologists (ASA) score, comorbidity, and the diagnosis and type of surgery. A total of 163 patients underwent emergency general surgery and were included. Mean age was 71 ± 7 years, and 59% were male. Overall, the incidence of postoperative delirium was 26%. Patients who developed postoperative delirium were more likely to be frail (40% vs 14%, p < 0.01), on more than 3 medications (29% vs 18%, p < 0.01), and were more likely to have 3 or more comorbidities (32% vs 21%, p < 0.01). On regression analysis, frail status (odds ratio [OR] 3.7 [2.4-4.2], p < 0.01) and receiving more than 3 medications (OR 1.3 [range 1.1-1.4], p < 0.01) were independent predictors of developing postoperative delirium. An episode of delirium was associated with longer hospital length of stay (LOS) (6 days vs 3 days, p < 0.01), higher odds of ICU admission (OR 2 [1.3-4.5], p < 0.01), longer ICU LOS (2 days vs 1 day, p < 0.01), and higher odds of unplanned intubation (OR 1.8 [1.2-3.4], p < 0.01). The incidence of delirium after EGS was 26%. Frailty and polypharmacy were associated with increased risk of delirium. Delirium appears to be associated with higher rates of in-hospital adverse events.

Nursing outcomes in medical wards (ESAMED Study): the results of a multicenter longitudinal study

Research on nursing outcomes attempted to identify the associated factors, however, with mainly retrospective or descriptive studies. In 2011, an Italian network was established and a multicentric longitudinal study aimed at exploring factors associated with nursing outcomes among in-hospital medical patients was started. To summarise (a) how the research project was originated, (b) which patients have been involved, variables and instruments used, (c) the main findings, and (d) the lessons learnt. 12 acute medical units from 11 Italian hospitals were involved. A consecutive sample was adopted: on a daily basis, data has been collected at the (a) patient; (b) nursing care, and (c) hospital levels. The effect of the variability in the amount of nursing care and skill mix in medical units was explored on the following outcomes: (a) hospital-acquired functional dependence, (b) prevalence and incidence of (i) episodes of hyperactive delirium, (ii) avoidable pressure ulcers; (iii) peripheral venous catheter phlebitis; (c) dissatisfaction with the nursing care; and (d) in-hospital mortality; 1464 out of 2082 eligible patients were involved. The frequency and reasons of Missed Nursing Care (MNC), as well as the presence of family caregivers at the bedside were also measured. The study confirmed that (a) the amount of nursing care provided by graduate nurses improves patient outcomes; (b) a skill mix in favour of nursing aides, negatively impacts on patients' outcomes; and (c) a higher frequency of MNC threatens patient outcomes.

Refractory delirium in palliative care sitting

This paper describes the management of a 65 years old male patienttransferred to the palliative care ward from the Intensive Care Unit, withbrain metastasis and infarction admission, epilepsy, neurological dysfunction,cognitive impairment and a history of previous delirium episodes. Wediscuss four delirium assessment methods and possible collaborativemultidisciplinary approaches to manage persistent delirium in palliative carepatients.1.Agar M, Alici Y, and Breitbart (2015)W.17.5 Delirium.
