Adherence to optimal delirium management practices in intensive care units in Brazil: a nationwide survey.

Effective delirium management is crucial, considering its association with adverse outcomes. Adherence to best practices has the potential to reduce the incidence and prevalence of delirium and improve health outcomes. The objectives of this project were to describe self-assessed adherence to best practices in delirium management by health care professionals in intensive care units (ICUs) in Brazil, assess the health care professionals' perception of the importance of adequate delirium prevention and treatment in ICUs, and compare the compliance rates with best practices between public and private ICUs. A cross-sectional study was conducted in Brazil using an online questionnaire consisting of three parts, namely, data about the health care professionals and the ICU in which they worked; statements about the 17 best practices; and questions related to perceptions of delirium prevention and management by ICU physicians and nurses. The survey was sent to email addresses registered with the Brazilian Association of Intensive Care Medicine. The compliance rate exceeded 50% for only eight best practices. These included the identification and management of pressure sores and falls in delirium patients, with compliance rates of 77.8% and 74.1%, respectively. Among ICU professionals in Brazil, adherence to best practices in delirium management is low, particularly for practices involving patient education and involvement of their relatives in their care. These results emphasize the importance of enhancing delirium management in Brazilian health care institutions, regardless of hospital classification. http://links.lww.com/IJEBH/A274.

Manejo do delirium para o clínico geral

This paper is part of a larger project in medical education regarding central themes in psychiatry and aims to improve the clinical knowledge of medical students and practitioners both. Given the high prevalence of delirium in hospital settings and the poor prognosis associated with it, it is of the utmost importance that not only its adequate management is known, but also measures to prevent it are implemented widely. Delirium is a clinical syndrome in which the main components are altered attention, fluctuating level of consciousness, and disorganized thought; generally, symptoms fluctuate in intensity during the day. Delirium has hyperactive, hypoactive, and mixed presentations. Prevalence is higher in critically ill patients and its presentation denotes a worse prognosis; therefore, its early detection and prevention are paramount. Treatment consists of treating base causes, precipitating factors, and administering antipsychotic medications, commonly haloperidol for hyperactive forms.

Results From A Snapshot Survey Of Delirium Prevalence, Detection And Care In Hospitals In Ireland On World Delirium Awareness Day

Abstract Background Delirium, an acute encephalopathy characterized by acute onset, fluctuation, and attention deficits, is associated with increased mortality and morbidity, and with precipitation or worsening of dementia. Thus, delirium prevention, timely detection, and appropriate management are crucial. Methods On World Delirium Awareness Day (15th March 2023), a global survey was assessed delirium prevalence and care. A senior clinical staff member on each participating ward reported on delirium prevalence at 8AM and 8PM, and on usual ward practice; data was entered into an online survey by a data collector (typically an on-site clinician, visiting several wards to record data). This study reports data from Irish hospitals. Results In total, 132 wards from 15 hospitals across Ireland participated. Delirium prevalence, using a formal assessment tool, was 15.9% across all wards, highest in geriatric wards (20.5%). However, on wards where 'personal judgment' to detect delirium was utilized, the prevalence rate was 11.5%, implying that delirium may be missed on these wards. Intensive care units (76.2%), geriatric wards (70%), and Emergency Departments/Acute Medical Units (ED/AMUA; 66.7%) had the highest rate of written delirium protocols. Similarly, staff training (51.5% overall), was highest in ED/AMAU (88.9%), followed by general surgical (66.7%), and geriatrics wards (60%). In contrast, only 30.8% (4/13) of non-acute wards had provided staff with delirium training in the preceding year. Having at least one training session in the preceding year was associated with higher use of formal delirium tools (18.8% versus 60.3%). Wards reported staff training/educating as the main care improvement priority; 72.7% of wards identified lack of time to train staff as a key barrier. Conclusion Delirium is prevalent in Irish hospitals and appears under-detected without formal screening. Training staff in delirium-related skills, including the use of simple screening tools for delirium detection and causation, could be paramount to improving patient outcomes.

Incidence of Delirium in ICU Patients With and Without COVID-19 in a Costa Rican Hospital.

Delirium is a common and serious neurological complication in intensive care units (ICUs), often leading to poor patient outcomes and increased mortality. This study aimed to compare the incidence of delirium in ICU patients with COVID-19 to those with other respiratory infections in a private hospital in Costa Rica. Additionally, it evaluated the prevalence, severity, duration, and treatment of delirium in these critically ill patients. A retrospective observational study was conducted, analyzing multiple variables obtained from the electronic health records of patients hospitalized in the ICU of Hospital Clinica Biblica. The study included patients admitted between January 2020 and December 2023. It compared the incidence of delirium among patients admitted for COVID-19 and those admitted for other diagnoses. The main outcomes measured were the incidence of delirium and the correlation of its management with international guidelines. The measures included the use of mechanical ventilation, the development of delirium, and the use of sedatives. A total of 137 patients were analyzed, of whom 57.7% were over 70 years old, 67.2% were men, 45.2% were admitted with a diagnosis of COVID-19, 90.5% used mechanical ventilation, and 49.6% of patients developed delirium. Dexmedetomidine was the most used sedative, which was the only one that showed a significant relationship with the development of delirium (p=0.0002). Delirium management was mainly done through the administration of dexmedetomidine (52.9%) and quetiapine (41.2%). There was no correlation between delirium development and mortality (p=0.2670). The study results do not show a significant relationship between COVID-19-positive patients and the development of delirium. Similarly, no higher mortality was observed in those patients who experienced delirium during their ICU stay.

Delirium in nursing home residents: is there a role of antidepressants? A cross sectional study

BackgroundDelirium is strongly associated with poor health outcomes, yet it is frequently underdiagnosed. Limited research on delirium has been conducted in Nursing Homes (NHs). Our aim is to assess delirium prevalence and its associated factors, in particular pharmacological prescription, in this care setting.MethodsData from the Italian “Delirium Day” 2016 Edition, a national multicenter point-prevalence study on patients aged 65 and older were analyzed to examine the associations between the prevalence of delirium and its subtypes with demographics and information about medical history and pharmacological treatment. Delirium was assessed using the Assessment test for delirium and cognitive impairment (4AT). Motor subtype was evaluated using the Delirium Motor Subtype Scale (DMSS).Results955 residents, from 32 Italian NHs with a mean age of 84.72 ± 7.78 years were included. According to the 4AT, delirium was present in 260 (27.2%) NHs residents, mainly hyperactive (35.4%) or mixed subtypes (20.7%). Antidepressant treatment with selective serotonin reuptake inhibitors (SSRIs) was associated with lower delirium prevalence in univariate and multivariate analyses.ConclusionsThe high prevalence of delirium in NHs highlights the need to systematically assess its occurrence in this care settings. The inverse association between SSRIs and delirium might imply a possible preventive role of this class of therapeutic agents against delirium in NHs, yet further studies are warranted to ascertain any causal relationship between SSRIs intake and reduced delirium incidence.

Delirium prevalence in emergency department patients: A systematic review and meta-analysis.

Delirium is a common acute mental disorder, and its adverse outcomes often cause distress to both patients and their families. Despite its prevalence in patients treated in emergency departments, delirium is frequently overlooked. This study aims to systematically evaluated and meta-analysis the prevalence of delirium among emergency patients, providing insights into its prevalence and offering guidance for its management and prevention. Observational studies on the prevalence of delirium in emergency departments were systematically searched in PubMed, Embase, the Cochrane Library and Medline databases. Relevant English-language studies published up to 18 September 2023 were reviewed, and meta-analysis was conducted using Stata 14.0 software. Quality assessment of included literature was performed using the methodological index for non-randomized studies (MINORS), and publication bias was assessed using Egger's test. Thirteen studies encompassing a total sample size of 33 839 cases were included, with 3082 cases of delirium incidents. The findings revealed a 15% prevalence rate of delirium in emergency departments, with a 95% confidence interval (CI) of (0.10, 0.20) and an overall heterogeneity of 98.37% (p = .000). Among emergency department patients over 65 years of age, the prevalence of delirium was 12%, with a 95% CI of (0.07, 0.19) and a heterogeneity of 94.59%. For patients over 18 years of age, the prevalence was 17%, with a 95% CI of (0.10, 0.25) and a heterogeneity of 98.94%. This meta-analysis reveals an overall 15% prevalence rate of delirium among patients in emergency departments. In clinical practice, emergency medical staff should strengthen the screening and management of emergency delirium patients.

Effect of intra-operative Magnesium sulphate on the occurrence of post-operative delirium and insomnia in patients undergoing lumbar fixation: a randomized controlled trial

BackgroundOver the last two decades, a large body of literature has focused on studying the prevalence and outcome of the postoperative delirium and sleep disturbance. The aim of this work was to evaluate the effect of intraoperative administration of Magnesium sulphate on the occurrence of post-operative delirium and insomnia in patients undergoing lumbar fixation.MethodsThis prospective randomized controlled trial was carried out on 80 patients indicated for lumbar fixation; 40 of them received conventional general anesthesia with extra administration of intraoperative magnesium sulphate (Mg sulphate group), and the other 40 received conventional general anesthesia only (control group). Both groups were submitted to pre-operative assessment of depression using Beck Depression inventory (BDI) scale, pre-operative assessment of fatigue using a fatigue questionnaire, pre- and post-operative assessment of insomnia using Insomnia severity index (ISI), post-operative assessment of delirium using Memorial delirium assessment scale (MDAS), post-operative assessment of pain using Visual Analogue Scale (VAS), and pre- and post-operative Quantitative electroencephalography (QEEG).ResultsMg sulphate administration, age, pre-operative BDI, pre-operative ISI, and post-operative VAS were independent predictors of post-operative ISI (P-value < 0.001, 0.047, 0.021, < 0.001, and < 0.001 respectively). Age and post-operative VAS were independent predictors of post-operative MDAS (P-value = 0.008, 0.013 respectively). Mg sulphate administration and pre-operative ISI were independent predictors of post-operative VAS (P-value = 0.010, 0.006 respectively).ConclusionThere was a significant relationship between intraoperative Mg sulphate administration and both post-operative insomnia and pain in unadjusted and adjusted analysis.

2327 Delirium predicts poor outcomes in Parkinson's disease

Abstract Introduction Reported delirium prevalence in inpatients with Parkinson’s disease (PD) varies widely across the literature and is often underreported. Delirium is associated with an increased risk of institutionalisation, dementia, and mortality, but to date there are no comprehensive prospective studies in PD. We aimed to determine delirium prevalence in PD compared to older adults and its associated risk with adverse outcomes. Method Participants from the ‘Defining Delirium and its Impact in Parkinson’s Disease’ (DELIRIUM-PD) and the ‘Delirium and Cognitive Impact in Dementia’ (DECIDE) studies were included. People with PD (DELIRIUM-PD) or older adults from the Cognitive Function and Ageing Study II – Newcastle cohort (DECIDE) admitted to hospitals in Newcastle were approached to take part. Delirium was assessed prospectively using the Diagnostic and Statistical Manual of Mental Disorders – 5th Edition criteria. Outcomes were determined by medical note reviews and home visits 12 months post discharge. Cox regression or binary logistic regression were used to evaluate the effect of delirium on institutionalisation, dementia, and mortality, independent of covariates. Results Delirium developed in 66.9% (n = 81/121) of PD participants compared to 38.7% (n = 77/199) of controls (p &amp;lt; 0.001). Delirium was associated with a significant increased risk of developing dementia in one year in PD (OR = 6.1 (1.3–29.5), p = 0.024) and in controls (OR = 13.4 (2.5–72.6), p = 0.003). However, in only PD participants, delirium was associated with a significantly higher risk of institutionalisation (OR = 10.7 (2.1–54.6), 0.004) and mortality (HR = 3.3 [95% CI 1.3–8.6], p = 0.014). Conclusion This is the first comprehensive prospective study of delirium in PD, showing that over two-thirds develop delirium during hospitalisation compared to a third of older adults. Delirium in PD is associated with a significant risk of dementia, institutionalisation, and death in one year. Furthermore, this is the first study to show that PD increases the risk of mortality and institutionalisation over and above a delirium in older adults.

2323 Prevalence of delirium, dementia and cognitive test deficits, hospital-wide and by specialty in &amp;gt; 50,000 unplanned admissions

Abstract Introduction Over one-third of older people with unplanned admissions to hospital are frail, but data on the burden of delirium, dementia and other cognitive frailty are lacking. Reliable hospital-wide and specialty-specific prevalence estimates are needed for service-planning including understanding the role of non-geriatricians in caring for this population. Methods ORCHARD includes pseudo-anonymised EPR data for consecutive admissions with a length of stay of &amp;gt;1 day (2017–2019) to four hospitals in Oxfordshire (population = 800,000). Data are collected using a standard cognitive screen comprising dementia history, delirium diagnosis (Confusion Assessment Method-CAM), and 10-point Abbreviated Mental Test-AMTS that is mandated on admission for all patients &amp;gt;70 years. Cognitive frailty was defined as delirium, diagnosed dementia, delirium+dementia or AMTS&amp;lt;8 without delirium/dementia. We analysed the ORCHARD data to determine the prevalence of delirium/cognitive frailty trust-wide and by specialty (n = 29 with &amp;gt;50 admissions). Results Among 51,202 admissions with mean/sd age = 82/7 years and Hospital Frailty Risk Score = 8/6, any cognitive frailty was present in 34.5% (95%CI 34.0–34.9%; n = 17,466) of which delirium accounted for 14.6% (n = 7411), delirium+dementia = 9.4% (n = 4757), dementia = 7.5%, (n = 3784), AMTS&amp;lt;8 = 3% (n = 1514). The prevalence of cognitive frailty in general medicine, general surgery and trauma/orthopaedics, which accounted for 80% of admissions (n = 41,016), was 41% (n = 13,879), 21% (n = 801) and 35% (n = 1304) in each, respectively. The prevalence was 44% in geriatric medicine admissions (n = 133/301), 36% in palliative (n = 128/356), 29% in stroke (n = 135/468), 27% in infectious disease (n = 41/152), 22% in neurosurgery (n = 154/702) and 10–20% in all other specialties except two. Delirium was the most prevalent form of cognitive frailty in 24/29 specialties. Discussion Cognitive frailty is common in older unplanned hospital admissions across a broad range of specialties, with delirium accounting for most cases. Our findings support the need for hospital-wide and specialty-specific training and service development to reflect the needs of these older complex patients and increased emphasis on delirium in policy.

Cardio Delirium Day: national study on the prevalence of delirium in Italian cardiology wards

To date delirium prevalence in the adult acute Italian hospital cardiac population is unknown. In a multicenter study, we assessed the prevalence of delirium over a single day among a population of patients admitted to acute cardiac hospital wards in Italy. This is a point prevalence study (called "Cardio Delirium Day") which involved 55 Italian cardiologic centers (23 North, 18 Central, 12 South, 2 Sardinia) that collected data on 152 patients older than 65 years hospitalized on March 15, 2023. Delirium was assessed on the same day in all patients using the Confusion Assessment Method for the Intensive Care Unit algorithm, a validated and briefly administered tool which does not require specialized training. We also collected data about clinical variables, functional and nutritional status, dementia, comorbidity, medications, and physical restraints. The mean sample age was 79.0 ± 10 years (33% female). Delirium was diagnosed in 25 patients (16.4%); 17.1% were hospitalized in the intensive cardiac care unit and 13.8% in the cardiology ward (p=NS). Hyperactive was the commonest subtype (48%), followed by mixed (36%) and hypoactive type (8%). In a multivariate logistic regression, male sex (odds ratio [OR] 3.81, 95% confidence interval [CI] 1.18-12.26; p=0.025), chronic obstructive pulmonary disease (OR 0.24, 95% CI 0.063-0.66; p=0.008), sensorial deficit (OR 3.75, 95% CI 1.18-11.95; p=0.025), sleep deprivation (OR 5.81, 95% CI 1.47-22.9; p=0.012) and the presence of ≥3 precipitating factors (OR 7.63, 95% CI 2.32-25.2; p=0.001) were independent predictors of delirium. Delirium occurred in 16.4% of patients in a cardiology setting. The "Cardio Delirium Day" project might become a useful method to assess delirium over time and sensitize the interest and the culture of Italian cardiology in this important aspect of hospital care.

Delirium prevalence and delirium literacy across Italian hospital wards: a secondary analysis of data from the World Delirium Awareness Day 2023.

Delirium, a common medical emergency among hospitalized patients, requires effective detection and management protocols. This study aims to evaluate the delirium point prevalence and its management across Italian hospitals, categorized by delirium literacy levels. Additionally, it seeks to identify prevailing barriers and future priorities in delirium practice and research. We analyzed data from World Delirium Awareness Day (WDAD) on March 15th, 2023, collected by participating clinicians in Italian hospitals. High delirium literacy (HL) was determined based on the use of validated delirium assessment tools and the presence of a written protocol for delirium management. Conversely, low delirium literacy (LL) was determined by meeting only one or neither of these criteria. Fifty-eight hospital wards participated in the survey, with 25 (43.1%) classified as HL. The overall reported point prevalence of delirium was found to be approximately 10%. Notably, the reported prevalence was twice as high in the HL group compared to the LL group. Despite minimal differences compared to the other group, the HL group demonstrated greater adherence to appropriate delirium management strategies, encompassing both non-pharmacological and pharmacological strategies. Critical gaps in delirium care emerged, including suboptimal management practices, barriers to implementing evidence-based strategies, and insufficient awareness and training among professionals. The study highlights the suboptimal identification and management of delirium among Italian hospitals, emphasizing the necessity of enhancing awareness and implementing evidence-based strategies. Addressing these shortcomings is crucial for optimizing delirium care, improving patient outcomes, and mitigating the burden of delirium in hospital settings.

Association of Hyperoxia During Cardiopulmonary Bypass and Postoperative Delirium in the Pediatric Cardiac ICU.

ICU delirium commonly complicates critical illness associated with factors such as cardiopulmonary bypass (CPB) time and the requirement of mechanical ventilation (MV). Recent reports associate hyperoxia with poorer outcomes in critically ill children. This study sought to determine whether hyperoxia on CPB in pediatric patients was associated with a higher prevalence of postoperative delirium. Secondary analysis of data obtained from a prospective cohort study. Twenty-two-bed pediatric cardiac ICU in a tertiary children's hospital. All patients (18 yr old or older) admitted post-CPB, with documented delirium assessment scores using the Preschool/Pediatric Confusion Assessment Method for the ICU and who were enrolled in the Precision Medicine in Pediatric Cardiology Cohort from February 2021 to November 2021. None. Of 148 patients, who underwent cardiac surgery, 35 had delirium within the first 72 hours (24%). There was no association between hyperoxia on CPB and postoperative delirium for all definitions of hyperoxia, including hyperoxic area under the curve above 5 predetermined Pao2 levels: 150 mm Hg (odds ratio [95% CI]: 1.176 [0.605-2.286], p = 0.633); 175 mm Hg (OR 1.177 [95% CI, 0.668-2.075], p = 0.572); 200 mm Hg (OR 1.235 [95% CI, 0.752-2.026], p = 0.405); 250 mm Hg (OR 1.204 [95% CI, 0.859-1.688], p = 0.281), 300 mm Hg (OR 1.178 [95% CI, 0.918-1.511], p = 0.199). In an additional exploratory analysis, comparing patients with delirium within 72 hours versus those without, only the z score for weight differed (mean [sd]: 0.09 [1.41] vs. -0.48 [1.82], p < 0.05). When comparing patients who developed delirium at any point during their ICU stay (n = 45, 30%), MV days, severity of illness (Pediatric Index of Mortality 3 Score) score, CPB time, and z score for weight were associated with delirium (p < 0.05). Postoperative delirium (72 hr from CPB) occurred in 24% of pediatric patients. Hyperoxia, defined in multiple ways, was not associated with delirium. On exploratory analysis, nutritional status (z score for weight) may be a significant factor in delirium risk. Further delineation of risk factors for postoperative delirium versus ICU delirium warrants additional study.

Objective predictors for delirium tremens based on physiological and metabolic parameters

BACKGROUND: The search for markers and predictors of complicated forms of alcoholism, which include alcoholic delirium and acute psychotic reactions with hallucinatory and delusional phenomena, is one of the actual problems of modern addiction medicine. AIM: Clinical validation of a model for early detection of patients at high risk of developing complicated alcohol withdrawal syndrome (AWS) based on laboratory diagnostics. SUBJECTS AND METHODS: A prospective, cohort, observational study was performed. The study included 200 patients; 9 were excluded. The included patients were distributed as follows: uncomplicated AWS, 98 patients (51.3%); alcohol delirium, 67 patients (35.1%); and alcohol-induced psychotic disorder, 26 patients (13.6%). Potassium, sodium, calcium, and platelet count were compared between the groups, and the relationships between sex, age, and potassium levels in patients with alcohol delirium were studied. RESULTS: Potassium, sodium, and platelet count were significantly different in patients with alcohol delirium and in those with uncomplicated AWS and alcohol-induced psychotic disorder. Blood calcium levels were significantly different between patients with alcohol delirium and uncomplicated AWS. Women were found to be less sensitive to metabolic disorders that developed as a result of alcohol consumption, as evidenced by lower incidence of delirium. The high prevalence of alcohol delirium among older patients is a consequence of decompensation of metabolic regulation mechanisms. CONCLUSIONS: Predictive model of alcohol delirium, based on the results of blood potassium level study, proved effectiveness in clinical application.

Comparison of the Efficacy of Postoperative Pain Relief in Ultrasound Guided Fascia Illiaca Compartment Block versus Epidural Block on Quality of Recovery (QOR-15) in Patients Undergoing Femoral Surgery

Background: The occurrence of femoral fractures is quite high. The quality of life gets affected to a large extent due to pain and post-operative delirium. Various regional block techniques like Fascia illiaca compartment block, lumbar epidural analgesia, femoral nerve block, etc. have been described for femoral fractures. In this study, we compared the efficacy of post-operative pain relief FICB and Epidural block on quality of recovery (QOR-15) in patients undergoing femoral surgery. Methods: This study included 40 patients wherein 20 patients were given FICB and 20 patients were given Epidural block. The patients were followed up for post-operative pain relief, Quality of Recovery, occurrence of delirium, disability and fraility. Results: Quality of recovery QOR-15 was similar for both the groups preoperatively as well as at 24 hour and 48 hours post-operatively. Additionally, there was no difference in the time taken to administer the block, postoperative VAS score on movement and rest, requirement of additional analgesia and opioid consumption. Moreover, there were no significant differences in WHO disability assessment, modified frailty score, prevalence of delirium, mortality, morbidity and side effects of techniques. However, the total duration of hospital stay (in days) was found to be significantly more in the epidural group as compared with the FICB group (5.75±1.61 vs 4.75±1.16; P=0.38). Conclusion: Ultrasound guided fascia iliaca compartment block is a tangible alternative to epidural block in patients undergoing femoral fracture repair.

Delirium Screening in Critically Ill Children: Secondary Analysis of the Multicenter PICU Up! Pilot Trial Dataset, 2019-2020.

To determine the patient-level factors associated with performing daily delirium screening in PICUs with established delirium screening practices. A secondary analysis of 2019-2020 prospective data from the baseline phase of the PICU Up! pilot stepped-wedge multicenter trial (NCT03860168). Six PICUs in the United States. One thousand sixty-four patients who were admitted to a PICU for 3 or more days. None. Of 1064 patients, 74% (95% CI, 71-76%) underwent delirium screening at least once during their PICU stay. On 57% of the 8965 eligible patient days, screening was conducted. The overall prevalence of delirium was 46% across all screened days, and 64% of screened patients experienced delirium at some point during their PICU stay. Factors associated with greater adjusted odds ratio (aOR) of increased daily delirium screening included PICU stay longer than 15 days compared with 1-3 days (aOR 3.36 [95% CI, 2.62-4.30]), invasive mechanical ventilation as opposed to room air (aOR 1.67 [95% CI, 1.32-2.12]), dexmedetomidine infusions (aOR 1.23 [95% CI, 1.04-1.44]) and propofol infusions (aOR 1.55 [95% CI, 1.08-2.23]). Conversely, decreased aOR of daily delirium screening was associated with female gender (aOR 0.78 [95% CI, 0.63-0.96]), and the administration of continuous infusions of opioids (aOR 0.75 [95% CI, 0.63-0.90]) or ketamine (aOR 0.48 [95% CI, 0.29-0.79]). Neither patient age, the presence of family or physical restraints, or benzodiazepine infusions were associated with daily delirium screening rates. In the 2019-2020 PICU UP! cohort, across six PICUs, delirium screening occurred on only 57% of days, despite the presence of established practices. Female gender, patients in the early stages of their PICU stay, and patients not receiving mechanical ventilation were associated with lower odds of daily delirium screening. Our results highlight the need for structured quality improvement processes to both standardize and increase the frequency of delirium screening.

Informal judgement of delirium status underestimates delirium prevalence: World Delirium Awareness Day point prevalence results from Ireland

Introduction Delirium is an encephalopathy characterized by acute onset, fluctuation, and prominent deficits in attention and alertness, due to one or more physical disorders, interventions or medications. It is associated with increased mortality and morbidity, and with incidence and worsening of dementia; thus, delirium prevention and timely detection and appropriate management are crucial. Objective This study aimed to determine delirium prevalence in Irish clinical sites. Methods The overall study was an observational, cohort study of the point prevalence of delirium (and current delirium practice) in multiple clinical sites on a single day (i.e. World Delirium Awareness Day, March 2023). In this study, the point prevalence of delirium is reported in Irish sites. Results In total, 132 wards from 15 hospitals across Ireland participated in this study, including general medical, surgical and specialised wards, and some long-term care and rehabilitation wards. Overall, 27% of patients on wards which reported using a formal tool had not been assessed for delirium. Delirium prevalence, using a formal assessment tool, was 15.9% overall, with the highest rate in geriatric wards (20.5%). However, on wards where ‘personal judgment’ to detect delirium was utilized, the prevalence rate was 11.5%, implying that delirium may have been under-detected on these wards. Conclusions Delirium screening can quickly rule out delirium or lead to more formal assessment where screening is positive or equivocal. Delirium is prevalent in Irish hospitals and appears to be under-detected unless a formal screening tool is used; equally, delirium screening is not universally applied on wards reporting that they use a formal tool. Together, this indicates that delirium is still under-diagnosed in Irish hospitals.

Delirium care in hospitals in Ireland on World Delirium Awareness Day 2023

BackgroundAcute, transient, but sometimes persistent, delirium is characterized by a sharp disruption in attention, consciousness, and cognitive function, and can be caused by many medications and disorders. Delirium occurrence and negative consequences, such as falls and functional decline, can be decreased with multifactorial prevention and timely detection.AimsTo describe current clinical practice in relation to the prevention, assessment, and management of delirium in Irish hospitals; awareness-raising and educational activities; and barriers to good practice.MethodsOn World Delirium Awareness Day (15th March 2023), a global survey was conducted of delirium prevalence and care. A senior clinical staff member on each participating ward reported on delirium prevalence at 8AM and 8PM, and on usual ward practice; this data was entered into an online survey by a data collector (typically a clinician from the site, visiting several wards to record data). This study reports data from Irish hospitals.ResultsIn total, 132 wards from 15 hospitals across Ireland participated. Almost 60% of wards used ‘personal judgment’ for delirium assessment. Having at least one delirium training session in the preceding year was associated with greater use of a formal assessment tool (60.3% versus 18.8%; p < 0.001). Wards reported staff training/education as the main priority to improve care, but 72.7% of wards identified insufficient time to train staff as a key barrier.ConclusionsClinical practice related to delirium care requires improvement. Awareness raising and staff training require more focus and time in busy clinical settings.

Discovery of Delirium Biomarkers through Minimally Invasive Serum Molecular Fingerprinting.

Delirium presents a significant clinical challenge, primarily due to its profound impact on patient outcomes and the limitations of the current diagnostic methods, which are largely subjective. During the COVID-19 pandemic, this challenge was intensified as the frequency of delirium assessments decreased in Intensive Care Units (ICUs), even as the prevalence of delirium among critically ill patients increased. The present study evaluated how the serum molecular fingerprint, as acquired by Fourier-Transform InfraRed (FTIR) spectroscopy, can enable the development of predictive models for delirium. A preliminary univariate analysis of serum FTIR spectra indicated significantly different bands between 26 ICU patients with delirium and 26 patients without, all of whom were admitted with COVID-19. However, these bands resulted in a poorly performing Naïve-Bayes predictive model. Considering the use of a Fast-Correlation-Based Filter for feature selection, it was possible to define a new set of spectral bands with a wider coverage of molecular functional groups. These bands ensured an excellent Naïve-Bayes predictive model, with an AUC, a sensitivity, and a specificity all exceeding 0.92. These spectral bands, acquired through a minimally invasive analysis and obtained rapidly, economically, and in a high-throughput mode, therefore offer significant potential for managing delirium in critically ill patients.
