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 Subsyndromal delirium, a condition in which patients exhibit some, but not all, of the symptoms of delirium, can negatively affect the outcomes of patients with cancer. However, the incidence of subsyndromal delirium in patients with gastric cancer is unknown. Here, we investigated the incidence and risk factors of subsyndromal delirium after curative resection of gastric cancer. Methods We recruited consecutive patients with gastric cancer who were scheduled for curative resection at a tertiary hospital. Patients’ subsyndromal delirium symptoms were serially assessed preoperatively and 1, 2, 3, and 7 days postoperatively using the Delirium Rating Scale-Revised-98 (DRS-R-98). A DRS-R-98 score of 8–14 at any postoperative assessment was considered to indicate subsyndromal delirium. Sociodemographic and pre−/intra-operative clinical data were also assessed. Logistic regression analyses were used to determine the associated risk factors. Results Data were analysed from 163 out of 217 eligible patients. Postoperative delirium occurred in one patient (0.6%) and subsyndromal delirium occurred in 19 patients (11.7%). Age ≥ 70 years (odds ratio, [OR] 3.85; 95% confidence interval [CI], 1.36–10.92; p = 0.011) and education level ≤ 9 years (OR, 3.98; 95% CI, 1.39–11.41; p = 0.010) were independent risk factors of subsyndromal delirium after adjusting for preoperative cognitive function. Other pre−/intra-operative variables including anxiety/depression, poor sleep quality, and anaesthesia duration were not associated with subsyndromal delirium. Conclusions In contrast to the low incidence of delirium among patients undergoing curative resection of gastric cancer, a substantial proportion of such patients experienced subsyndromal delirium. Considering the prognostic implications, more careful detection and management of subsyndromal delirium may be warranted in patients with gastric cancer.

Abstract
OBJECTIVE To better understand variation in reported rates of delirium, this study characterized delirium occurrence rate by department of service and primary admitting diagnosis. METHOD Nine consecutive years (2005-2013) of general hospital admissions (N=831,348) were identified across two academic medical centers using electronic health records. The primary admitting diagnosis and the treating clinical department were used to calculate occurrence rates of a previously published delirium definition composed of billing codes and natural language processing of discharge summaries. RESULTS Delirium rates varied significantly across both admitting diagnosis group (X210=12786, p<0.001) and department of care (X26=12106, p<0.001). In both cases obstetrical admissions showed the lowest incidences of delirium (86/109764; 0.08%) and neurological admissions the greatest (2851/25450; 11.2%). Although the rate of delirium varied across the two hospitals the relative rates within departments (r=0.96, p<0.001) and diagnostic categories (r=0.98, p<0.001) were consistent across the two institutions. CONCLUSIONS The frequency of delirium varies significantly across admitting diagnosis and hospital department. Both admitting diagnosis and department of care are even stronger predictors of risk than age; as such, simple risk stratification may offer avenues for targeted prevention and treatment efforts.

Abstract
OBJECTIVE To provide an overview of effective interventions aimed at reducing rates of adverse events in hospitals. DESIGN Systematic review of systematic reviews. DATA SOURCES PubMed, CINAHL, PsycINFO, the Cochrane Library and EMBASE were searched for systematic reviews published until October 2015. STUDY SELECTION English-language systematic reviews of interventions aimed at reducing adverse events in hospitals, including studies with an experimental design and reporting adverse event rates, were included. Two reviewers independently assessed each study's quality and extracted data on the study population, study design, intervention characteristics and adverse patient outcomes. RESULTS Sixty systematic reviews with moderate to high quality were included. Statistically significant pooled effect sizes were found for 14 types of interventions, including: (1) multicomponent interventions to prevent delirium; (2) rapid response teams to reduce cardiopulmonary arrest and mortality rates; (3) pharmacist interventions to reduce adverse drug events; (4) exercises and multicomponent interventions to prevent falls; and (5) care bundle interventions, checklists and reminders to reduce infections. Most (82%) of the significant effect sizes were based on 5 or fewer primary studies with an experimental study design. CONCLUSIONS The evidence for patient-safety interventions implemented in hospitals worldwide is weak. The findings address the need to invest in high-quality research standards in order to identify interventions that have a real impact on patient safety. Interventions to prevent delirium, cardiopulmonary arrest and mortality, adverse drug events, infections and falls are most effective and should therefore be prioritised by clinicians.

Efficacy of Non-Pharmacological Interventions to Prevent and Treat Delirium in Older Patients: A Systematic Overview. The SENATOR project ONTOP Series. PLoS One 2015; 10:e0123090.

Abstract
Background Non-pharmacological intervention (e.g. multidisciplinary interventions, music therapy, bright light therapy, educational interventions etc.) are alternative interventions that can be used in older subjects. There are plenty reviews of non-pharmacological interventions for the prevention and treatment of delirium in older patients and clinicians need a synthesized, methodologically sound document for their decision making. Methods and Findings We performed a systematic overview of systematic reviews (SRs) of comparative studies concerning non-pharmacological intervention to treat or prevent delirium in older patients. The PubMed, Cochrane Database of Systematic Reviews, EMBASE, CINHAL, and PsychINFO (April 28th, 2014) were searched for relevant articles. AMSTAR was used to assess the quality of the SRs. The GRADE approach was used to assess the quality of primary studies. The elements of the multicomponent interventions were identified and compared among different studies to explore the possibility of performing a meta-analysis. Risk ratios were estimated using a random-effects model. Twenty-four SRs with 31 primary studies satisfied the inclusion criteria. Based on the AMSTAR criteria twelve reviews resulted of moderate quality and three resulted of high quality. Overall, multicomponent non-pharmacological interventions significantly reduced the incidence of delirium in surgical wards [2 randomized trials (RCTs): relative risk (RR) 0.71, 95% Confidence Interval (CI) 0.59 to 0.86, I2=0%; (GRADE evidence: moderate)] and in medical wards [2 CCTs: RR 0.65, 95%CI 0.49 to 0.86, I2=0%; (GRADE evidence: moderate)]. There is no evidence supporting the efficacy of non-pharmacological interventions to prevent delirium in low risk populations (i.e. low rate of delirium in the control group)[1 RCT: RR 1.75, 95%CI 0.50 to 6.10 (GRADE evidence: very low)]. For patients who have developed delirium, the available evidence does not support the efficacy of multicomponent non-pharmacological interventions to treat delirium. Among single component interventions only staff education, reorientation protocol (GRADE evidence: very low)] and Geriatric Risk Assessment MedGuide software [hazard ratio 0.42, 95%CI 0.35 to 0.52, (GRADE evidence: moderate)] resulted effective in preventing delirium. Conclusions In older patients multi-component non-pharmacological interventions as well as some single-components intervention were effective in preventing delirium but not to treat delirium.

Abstract
To compare the efficacy of antipsychotics (APs) for delirium treatment in patients with cancer, 27 patients treated with 1 of the 4 APs, haloperidol (HPD), risperidone (RIS), olanzapine (OLZ), and quetiapine (QTP), were divided into 2 groups: long half-life (T1/2; HPD, RIS, and OLZ) versus short T1/2 (QTP) or the multiacting receptor-targeted APs (MARTAs; OLZ and QTP) versus the non-MARTA (HPD and RIS). The symptom severity was evaluated by the memorial delirium rating scale (MDAS) on days 0, 3, and 7 following intervention. Significant improvements in total MDAS scores were found in all groups on day 3. However, on day 7, only the short T1/2 group and MARTA group showed significant improvement. Consideration of an AP’s pharmacological properties may be helpful for improving the outcomes of pharmacological delirium intervention in patients with cancer.

Abstract
BACKGROUND We hypothesized that delirium contributes to combative behavior requiring intervention in hospitalized patients. Delirium identification would therefore potentially provide an opportunity for prevention and early identification of patients at risk, thereby improving safety for patients and staff. OBJECTIVE To determine whether delirium is associated with combative behavior requiring intervention in a general hospital population. DESIGN Case control study. SETTING A 336-bed, nonuniversity, teaching hospital serving adults in the Pacific Northwest. PATIENTS One hundred twenty consecutive hospitalized patients with combative behavior requiring intervention compared to 159 randomly selected inpatient control subjects, all from 2011. INTERVENTION Bivariate statistics were used to compare demographics; diagnoses; presence of delirium, dementia, substance use, other psychiatric diagnosis; medications; hospital length of stay; and discharge disposition. We used stepwise logistic regression to determine the association of combative behavior requiring intervention with delirium after adjustment for covariates. RESULTS Delirium preceding the combative behavior was present in 50% (60/120) of patients with combative behavior requiring intervention compared to 16% (26/159) of controls (P < 0.001). Combative-behavior patients were hospitalized longer (9.4 vs 4.5 days, P < 0.001), and were more likely to be discharged to a skilled nursing facility (26%, 31/120) or to leave against medical advice (10%, 12/120, P < 0.001). Delirium was strongly associated with combative behavior requiring intervention, after adjustment (odds ratio: 3.8, 95% confidence interval: 2.0-7.3, P < 0.001). CONCLUSION Delirium is strongly associated with combative behavior requiring intervention, which poses a significant safety risk for patients and staff.

Abstract
OBJECTIVE To investigate the evolution of delirium of nursing home (NH) residents and their possible predictors. DESIGN Post-hoc analysis of a prospective cohort assessment. SETTING Ninety NHs in Switzerland. PARTICIPANTS Included 14,771 NH residents. MEASUREMENTS The Resident Assessment Instrument Minimum Data Set and the Nursing Home Confusion Assessment Method were used to determine follow-up of subsyndromal or full delirium in NH residents using discrete Markov chain modeling to describe long-term trajectories and multiple logistic regression analyses to determine predictors of the trajectories. RESULTS We identified four major types of delirium time courses in NH. Increasing severity of cognitive impairment and of depressive symptoms at the initial assessment predicted the different delirium time courses. CONCLUSION More pronounced cognitive impairment and depressive symptoms at the initial assessment are associated with different subsequent evolutions of delirium. The presence and evolution of delirium in the first year after NH admission predicted the subsequent course of delirium until death.

Abstract
BACKGROUND Delirium is associated with high rates of morbidity and mortality in hospitalized medically ill patients. Haloperidol has historically been the agent of choice for the treatment of delirium, but recent studies have explored the efficacy of second-generation antipsychotics such as quetiapine. The unique pharmacology of quetiapine may allow it to treat delirium and provide sedation without causing significant extrapyramidal side effects. PURPOSE To evaluate the efficacy of quetiapine for the treatment of delirium. DATA SOURCES A search was conducted in MEDLINE and Embase (January 1960-December 2012) using keywords "quetiapine," "second-generation antipsychotic," "atypical antipsychotic," "delirium," and "agitation." STUDY SELECTION AND DATA EXTRACTION The search was limited to English-language articles and trials with treatment of delirium as the primary end point. Eight trials met this inclusion criterion. DATA SYNTHESIS Two randomized controlled trials, 5 open-label studies, and 1 retrospective cohort study evaluating quetiapine for the treatment of delirium were reviewed. One randomized controlled trial showed no differences in total mean delirium scores, but found the rate of delirium improvement was significantly shorter with quetiapine. The second randomized controlled trial showed the time to first resolution of delirium was shorter with quetiapine compared to placebo. Results of the open-label and retrospective cohort trials have also shown significant resolution of delirium from baseline and equal efficacy with quetiapine compared to amisulpride and haloperidol. CONCLUSIONS Quetiapine appears to be an effective and safe agent for the treatment of delirium in both general medicine and intensive care unit patients. The trials summarized suggest that quetiapine resolves symptoms of delirium more quickly than placebo and has equal efficacy compared to haloperidol and the atypical antipsychotic amisulpride. Further study is needed.

Abstract
BACKGROUND/AIMS A plethora of studies showed that delirium is common in hospitalized populations. We aimed to examine the characteristics of delirium patients referred to our Consultation-Liaison Psychiatry Unit (CLPU). METHODS Our CLPU database was used to obtain data of all referred patients admitted to our hospital and diagnosed with delirium. All referred nondelirious patients served as controls. RESULTS During one year, 483 patients were referred to the CLPU. Ninety-three (19.3%) were diagnosed with delirium. Delirious patients were older than nondelirious patients (P < 0.001), with 76.3% aged over 70 years. The majority of the referrals came from surgical specialties. Common etiological factors were fluid and electrolyte imbalance (29%), fractures (28%) and infections (24%), but laboratory tests for the investigation of the etiology prior to the consultation had been performed in only 12 patients (12.9%). The syndrome resulted in prolonged hospitalization and greater use of CLPU services. CONCLUSIONS Referrals for delirium are frequent in CLPUs in Greece. Although delirium is common, it remains a 'confusing' condition for health practitioners. The under-diagnosis of delirium, the prolonged hospitalization and the time that the CLPU dedicated to these patients underlines the role of the CLPU psychiatrists in the management of the syndrome.

Abstract
Delirium is a severe psychiatric syndrome that is highly prevalent in elderly general hospital patients. However, the diagnosis of delirium is often missed. The use of rating scales can be helpful in detecting and measuring delirium symptom severity. This article reviews recent developments regarding psychometric qualities, measurement goals, content and rating procedures of some of the available rating scales in clinical practice. Literature from the Medline files up to 2008 were collected, using the following search entries: delirium, (acute) confusion, assessment/rating scale and screening. Articles were selected if their title or summary were related to the development or applicability of delirium rating scales. The reference lists of relevant articles were searched for additional references. The rating scales were split up according to their purposes, screening or severity rating and were discussed for the following aspects: content (theoretical background, rating domains and items), interview (duration, format and assessors’ expertise) and psychometric qualities (reliability and validity). There were eight screening scales (Confusion Assessment Method [CAM], CAM for the Intensive Care Unit [CAM-ICU], Intensive Care Delirium Screening Checklist [ICDSC], Delirium Symptom Interview [DSI], NEECHAM Confusion Scale [NEECHAM], Cognitive Test for Delirium [CTD], Delirium Observation Screening [DOS] and Nursing Delirium Screening Scale [Nu-DESC]) and seven severity rating scales (Delirium Rating Scales [DRS], Memorial Delirium Assessment Scales [MDAS], Confusional State Evaluation [CSE], Delirium Severity Scales [DSS], Delirium Index [DI], Delirium-O-Meter [DOM] and Delirium Detection Scale [DDS] ) selected for further research. The CAM, NEECHAM and DOS and the CAM-ICU for the ICU appear to be the most suitable as screening instruments, depending on the type of rater (trained) physician or nurse. The (revised) Delirium Rating Scale (DRS-R-98) and the DOM appear to be particularly useful for measuring delirium severity or monitoring change.

Abstract
Delirium is a frequent complication of hospital admission, especially among the elderly. It can have serious consequences in terms of morbidity, mortality and decreased quality of life. Nevertheless, an extensive literature review found that it is poorly recognised and poorly managed by medical and nursing staff. Although some researchers have found that education programs for nurses can improve outcomes for patients with delirium, no research assessing nurses' knowledge was found. The objective of this research was to determine nurses' level of knowledge regarding delirium and its risk factors. A questionnaire survey sent to nurses at a teaching hospital found that nurse's knowledge of delirium was generally inadequate, although one ward which had had in-service education attained better results. It is recommended that cognitive assessment in general and delirium in particular be incorporated into nursing education. Improved education could potentially lead to improved health outcomes and considerable cost savings.

Abstract
OBJECTIVES The aim of this survey was to assess current structures for provision of consultation/liaison services to older people in the Republic of Ireland, and to ascertain the proportion of referrals to psychiatry of old age arising from consultation/liaison referrals. METHODS A postal questionnaire was sent to the 19 public sector, old age psychiatry services, operating in 2005. Information was obtained from 15 of these 19 services regarding the referrals they received in 2005. FINDINGS Consultation/liaison referrals make up 36% of total referrals to psychiatry of old age services. Two of 14 services had ring-fenced resources for consultation/liaison work. Three of 14 consultants described their service as having a significant liaison component. Location of the service and the criteria for accepting a referral are associated with the proportion of referrals that are consultation/liaison. CONCLUSIONS Consultation/liaison referrals make up a significant proportion of referrals. To provide an effective consultation/liaison service ring-fenced resources are required. Despite this recent long term strategies for national service development have neglected this area.

Abstract
INTRODUCTION AND BACKGROUND Delirium occurs frequently among elderly patients in the Emergency Department (ED), and accurate assessment is difficult without knowledge of the patient's usual cognitive functioning. This audit was designed to determine whether routine cognitive screening of elderly patients in ED could lead to early identification of delirium. METHODOLOGY An audit using the abbreviate mental test (AMT) and Confusion Assessment Method (CAM) tools assessed 28 elderly ED patients for the presence of delirium. RESULTS Fourteen (50%) of the 28 patients had no cognitive deficit on admission. Eleven (39.3%) displayed a cognitive deficit other than delirium and three (10.7%) had delirium, but only one had been diagnosed prior to the audit. DISCUSSION The prevalence rate of delirium in elderly ED patients was similar to those reported in the literature. The audit demonstrated the importance of cognitive assessment, as cognitive changes can be an early and sensitive indicator of physiological dysfunction. However, the AMT had limitations which inhibited its use in ED. A four question version known as the AMT4 may be more suitable. RECOMMENDATIONS ED nurses should routinely establish baseline cognitive functioning and assess for delirium. The AMT4 may be more suitable because of its brevity, but requires further research.

Abstract
Nonconvulsive status epilepticus is defined as a mental status change from baseline of at least a 30-min duration associated with constant or near-continuous ictal discharges on an electroencephalogram (EEG). Nonconvulsive status epilepticus is an often-overlooked diagnosis as a cause of acute confusional state. There are few case reports in dialysis patients. We are reporting 5 patients on chronic dialysis treatment who presented with an acute confusional state. Nonconvulsive status epilepticus was diagnosed by EEG and response to intravenous benzodiazepines. We recommend early EEG to be considered in the evaluation of dialysis patients with an acute confusional state.

Abstract
OBJECTIVE Delirium is highly prevalent in general hospitals but remains underrecognized and undertreated despite its association with increased morbidity, mortality, and health services utilization. To enhance its management, we developed guidelines covering all aspects, from risk factor identification to preventive, diagnostic, and therapeutic interventions in adult patients. METHODS Guidelines, systematic reviews, randomized controlled trials (RCT), and cohort studies were systematically searched and evaluated. Based on a synthesis of retrieved high-quality documents, recommendation items were submitted to a multidisciplinary expert panel. Experts scored the appropriateness of recommendation items, using an evidence-based, explicit, multidisciplinary panel approach. Each recommendation was graded according to this process' results. RESULTS Rated recommendations were mostly supported by a low level of evidence (1.3% RCT and systematic reviews, 14.3% nonrandomized trials vs. 84.4% observational studies or expert opinions). Nevertheless, 71.1% of recommendations were considered appropriate by the experts. Prevention of delirium and its nonpharmacological management should be fostered. Haloperidol remains the first-choice drug, whereas the role of atypical antipsychotics is still uncertain. CONCLUSIONS While many topics addressed in these guidelines have not yet been adequately studied, an explicit panel and evidence-based approach allowed the proposal of comprehensive recommendations for the prevention and management of delirium in general hospitals.

Abstract
The authors studied factors associated with referral of delirium patients to psychiatry consultation and its outcome implications. Characteristics and treatment outcomes of delirium patients referred to psychiatry were compared with those not referred. Referred patients were younger, had a more hyperactive subtype, greater substance abuse, less comorbid dementia, were more likely to be recognized as having delirium, and be prescribed medications. Improvement in referred patients was indicated by lower readmission rate postdischarge. No differences were noted in length of stay, discharge status, or mortality within 1 year of the index episode. Psychiatric interventions were moderately helpful. Patients' characteristics and delirium subtypes may influence referral and should inform future liaison efforts.

Abstract
BACKGROUND Despite the acknowledged clinical importance of delirium, research evidence for measures to improve its management is sparse. A necessary first step to devising appropriate strategies is to understand how common it is and what its outcomes are in any particular setting. OBJECTIVE To determine the occurrence of delirium and its outcomes in medical in-patients, through a systematic review of the literature. METHOD We searched electronic medical databases, the Consultation-Liaison Literature Database and reference lists and bibliographies for potentially relevant studies. Studies were selected, quality assessed and data extracted according to preset protocols. RESULTS Results for the occurrence of delirium in medical in-patients were available for 42 cohorts. Prevalence of delirium at admission ranged from 10 to 31%, incidence of new delirium per admission ranged from 3 to 29% and occurrence rate per admission varied between 11 and 42%. Results for outcomes were available for 19 study cohorts. Delirium was associated with increased mortality at discharge and at 12 months, increased length of hospital stay (LOS) and institutionalisation. A significant proportion of patients had persistent symptoms of delirium at discharge and at 6 and 12 months. CONCLUSION Delirium is common in medical in-patients and has serious adverse effects on mortality, functional outcomes, LOS and institutionalisation. The development of appropriate strategies to improve its management should be a clinical and research priority. As delirium prevalent at hospital admission is a significant problem, research is also needed into preventative measures that could be applied in community settings.

Abstract
Delirium is a mental disorder of acute onset and fluctuating course, characterized by disturbances in consciousness, orientation, memory, thought, perception, and behavior. It occurs in up to 50% of elderly hospital inpatients, many with preexisting dementia, and is associated with significant increases in functional disability, length of hospital stay, rates of death, and health care costs. Despite its clinical importance, delirium often remains undetected or misdiagnosed as dementia or other psychiatric illness. Awareness of the etiologies and risk factors of delirium should enable nurses to focus on patients at risk and to recognize delirium symptoms early. Knowledge of pharmacological and nonpharmacological treatments for delirium will provide the nurse with an arsenal of potential interventions in the care of the delirious hospitalized elder.

Abstract
Postoperative agitation has many potential etiologies and remains a significant clinical issue in the pediatric PACU setting. Caring for the agitated child requires a thorough assessment and calls for targeted interventions. This observational study evaluated nurses' diagnoses and treatment decisions regarding care of the agitated child. Nurses were observed during their care of 194 agitated children over a 3-month period. Pain and anxiety were the most commonly identified sources of agitation in the pediatric PACU setting (27% and 25% of cases, respectively), and nurses' targeted, primary interventions for these problems were fairly effective (48% and 67% effective, respectively). Anesthesia-induced agitation was less often identified as the etiology (11%), and primary interventions were more varied and less effective (38%). Physiologic abnormalities were identified as the source for agitation in only 3 cases, but went unrecognized for an extended period in 2 children. Results of this study underscore the complexity of assessment and treatment decisions when caring for agitated children. A decision algorithm based on this study is described as a potential aid toward differentiation of agitation and appropriate intervention.

Abstract
BACKGROUND When planning and delivering a liaison psychiatry service it is important to have an understanding of the research evidence supporting the use of interventions likely to be delivered by the service. AIMS To identify high-quality systematic reviews for all interventions in three defined areas of liaison psychiatry, to summarise their clinical implications and to highlight areas where more research is needed. The three areas were the psychological effects of physical illness or treatment, somatoform disorders and self-harming behaviour. METHOD Computerised database searching, secondary reference searching, hand-searching and expert consultation were used to identify relevant systematic reviews. Studies were reliably selected, and quality-assessed, and data were extracted and interpreted by two reviewers. RESULTS We found 64 high-quality systematic reviews. Only 14 reviews included meta-analyses. CONCLUSIONS Many areas of liaison psychiatry practice are not based on high-quality evidence. More research in this area would help inform development and planning of liaison psychiatry services.

Abstract
The features of delirium in patients being hospitalized due to respiratory diseases were investigated. From the inpatients in the respiratory medical ward of Tokyo Metropolitan Hiroo General Hospital over the course of 1 year, the patients who had delirium were diagnosed by a semistructured interview. The total number of subjects was 454, and patients with delirium were 43. Various clinical factors were compared between the delirium group and non-delirium group. In the delirium group, there were many elderly patients of 70 years or older. Moreover, there were many patients who had a chronic respiratory disease, patients in which the respiratory diseases were mutually complicated, and patients in whom other diseases combined with the respiratory disease in the delirium group. There were also many patients in the Intensive Care Unit (ICU), and patients with an endotracheal intubation or extubation. Based on the results of a multiple logistic regression analysis, for age, ICU accommodation, and endotracheal intubation, the value of the delirium group was more significant than that of the non-delirium group. In half of the patients from the delirium group, delirium developed within 1 week after hospitalization. In the patients who died in the hospital, however, delirium often developed days after they had been hospitalized. It was suggested that the later developed delirium had a relation to the prognosis.

Abstract
BACKGROUND: Organic Brain Syndromes (OBS) are often missed in clinical practice. Determining their varied presentations may help in earlier detection, better management, and, assessing prognosis and outcome. We described the in-patient referrals of patients suffering from the psychiatric effects of organic states and compared the symptomatology and mortality between those with the Acute and Chronic varieties. METHODS: 59 patients referred to our Consultation-Liaison (C-L) Psychiatry services and given a clinical diagnosis of OBS were selected over a 6-month period. Psychiatric and cognitive abnormalities and treatment regimes were recorded and fatality rates determined. Information regarding their condition 24 months after their index hospitalization was recorded. All data were entered into a proforma and analyzed after exclusion. RESULTS: The mean duration of detecting the symptoms by the physician was 3.52 days. The presence of a premorbid psychiatric illness had no influence on the clinical presentation but did on the mortality of patients with OBS (p = 0.029).Patients with the Acute syndrome had significantly more symptom resolution as compared to those with the Chronic syndrome (p = 0.001) but mortalityrates did not differ. Elderly patients and those with symptom resolution upon discharge did not show statistically significant higher mortality rates. The most popular combination of treatment was that of a low-dose neuroleptic and a benzodiazepine (34.7%). The need for maintenance treatment was not significantly different in any group, even in those with a past history of a functional disorder. CONCLUSION: Other than the Acute group having a significantly better outcome in terms of symptom resolution, our findings suggest that there was no significant difference in the clinical presentation between those with Acute or Chronic OBS. Mortality-wise, there was also no difference between the Acute and Chronic syndromes, nor was there any difference between the elderly and the younger group. There was also no significant difference in the need for continued treatment in both groups.

Abstract
Delirium is a disturbance of consciousness, cognition and perception that occurs frequently in medically ill patients. Although it is associated with increased morbidity and mortality, it is often not recognised and treated by physicians. Predisposing factors are believed to have multiplicative effects and include dementia, advanced age and male gender. Recently developed models allow for the estimation of the risk of developing delirium during a hospitalisation, based on predisposing factors and acute additional stressors. Although it has been shown to be efficacious, the prevention of delirium is underutilised. Prevention consists of aggressive management of known risk factors and early detection. Limited data exist to support specific pharmacological interventions for its treatment. In this article, the avail-able published literature regarding the prevention and treatment of delirium is systematically reviewed.

Abstract
The early detection and prevention of postoperative delirium and confusion has become an important issue in surgical ward management. With the aim of determining an objective technique for early detection of delirium, 64 patients admitted to a surgical ward before surgery were examined using the NEECHAM confusion scale. On the 2nd postoperative day they were tested again and divided into 3 groups on the basis of their NEECHAM scores: high risk, low risk, and no risk, for confusion. The trends of the NEECHAM scores in the 3 groups were compared, and the relationship between the NEECHAM scores and suspected clinical risk factors for delirium was investigated. Use of NEECHAM scaling enabled medical staff to identify cases of possible confusion early, indicating that the NEECHAM confusion scale should be useful for the detection of postoperative delirium and confusion in the surgical ward.

Abstract
The aim of this study was to illuminate nurses' experiences of the encounter with elderly patients who developed acute confusional state (ACS) in orthopaedic care. Forty-eight nurses with professional background as registered (n=26) or licensed practical nurses (n=22) who took part in the nursing care of acute confused patients were involved. Open-ended unstructured interviews were conducted with regard to the course of events, experiences and interpretation of what had happened during the ACS as well as the nurses' actions and encounter with the confused patient. The texts were analysed using manifest and latent content analysis, revealing that the nurses had difficulties in reaching the patients and their reality, and thus in understanding their experiences. Interpretation of the nurses' experiences showed that the nurses found it difficult to reach the patients' reality because the patients were in a divided and/or different world. They interpreted the patients as seeking solitude or company, keeping a distance or being suspicious of the nurses. The findings indicated that the interaction in the encounter between the acutely confused patients and the nurses indicated insufficient and/or broken reciprocity. The nurses used various strategies to meet the patients, being a companion and/or being a surrogate. They acted in the encounter based on their view of the patient and their ability to enter into and understand the patients' situation. The strategies were more or less successful, sometimes resulting in contact and calming the patients and in other cases increasing the patients' irritation and anger. The results were more successful when the strategies were derived from the nurses' interpretation of the patients' situation and the nurses paid attention to the patients and confirmed them.

Abstract
OBJECTIVES To ascertain the variation in strategies for managing delirium of physicians with expertise in geriatrics. DESIGN Cross-sectional mail survey. SETTING United States. PARTICIPANTS A probability sample of physician members of the American Geriatrics Society. MEASUREMENTS Management choices presented in a two-part case vignette of an older woman hospitalized with a hip fracture who develops mild and then severe delirium. RESULTS One hundred twenty-two respondents (43%) selected the three answers constituting current "best practice," 50 (18%) selected an unnecessary diagnostic test (brain imaging, lumbar puncture, or electroencephalogram), and 47 (17%) selected unnecessary pharmacologic therapy for mild delirium. For severe delirium, 270 (96%) selected pharmacological therapy, of whom 180 chose haloperidol alone, 55 chose lorazepam alone, 23 chose lorazepam in combination with haloperidol, and 12 wrote in another drug. Thirty percent of the respondents made any selection of lorazepam, alone or in combination with haloperidol, for mild or severe delirium. Sixty-one percent of those selecting haloperidol for severe delirium chose a dose greater than that recommended for geriatric patients. Sex, date of graduation from medical school, clinical specialty, completion of a geriatric fellowship, or certification in geriatrics had no significant effect on responses. CONCLUSIONS The common selection of lorazepam to treat delirium is troubling because benzodiazepines themselves are implicated in delirium. Selection of an initial dose of haloperidol higher than that recommended for geriatric patients by more than half of the respondents is also of concern. There is a paucity of sound clinical evidence to guide the choice of pharmacological agents for treating delirium in older hospitalized patients.

Abstract
Delirium has been recognized for the last 3 millennia and is the most common complication found in hospitalized patients aged 65 and older in the United States. However, critical basic science and clinical research did not progress until the DSM III criteria clearly defined delirium 20 years ago. The term delirium then replaced many nonspecific entities, such as acute confusion state, acute brain syndrome, metabolic encephalopathy, and toxic psychosis. This review discusses the epidemiology, risk factors, interventions, causes, management, and outcomes of delirium. The pathophysiology of delirium has the potential to radically alter our management of delirium and is a controversial area of research.

Abstract
BACKGROUND Opioids have an essential role in the management of pain in cancer patients, particularly those with advanced disease. Cognitive dysfunction is a recognized complication of opioid use. However, misconceptions and controversy surround the nature and prevalence of its occurrence. A projected increase in the aging cancer population highlights the need for a better understanding of this phenomenon. METHODS A critical appraisal of the literature evidence in relation to the pattern, pathophysiology, assessment, impact, and management of cognitive dysfunction due to opioid use in cancer pain management is given. RESULTS Studies in cancer patients with less advanced disease reveal subtle evidence of cognitive impairment, largely related to initial dosing or dose increases. In advanced cancer, opioid-induced cognitive dysfunction usually occurs in the form of delirium, a multifactorial syndrome. The presence of both cognitive impairment and delirium frequently is misdiagnosed or missed. Potential risk factors include neuropathic and incidental pain, opioid tolerance, somatization of psychologic distress, and a history of drug or alcohol abuse. Elevation of opioid metabolites with renal impairment may contribute to cognitive dysfunction. Recognition of opioid-related cognitive dysfunction is improved by objective screening. Successful management requires either dose reduction or a change of opioid, in addition to addressing other reversible precipitants such as dehydration or volume depletion. CONCLUSIONS Opioid-related cognitive dysfunction tends to be subtle in the earlier stages of cancer, whereas delirium, a more florid form with behavioral disturbance is likely to be present in the advanced cancer population. In patients with advanced disease, an optimal management approach requires careful clinical assessment, identification of risk factors, objective monitoring of cognition, maintenance of adequate hydration, and either dose reduction or switching to a different opioid.

Abstract
The hospitalized elderly are at an increased risk for poor outcomes such as increased length of stay, readmissions, functional decline, and iatrogenic complications, as compared with other age groups. Research related to the hospitalized elderly has identified factors associated with poor outcomes. Nurses and other healthcare team members may be able to identify elderly patients at risk for poor outcomes and target modifiable factors to minimize their negative impact. Clinical experience and research validate the conclusion that multidimensional, preventive risk factor modification balanced with acute illness treatment can result in positive outcomes for elderly patients.

Abstract
Delirium, which is experienced by 10-30% of inpatients, is commonly seen in daily practice. A survey was conducted of the delirium medications, and results were obtained from 28 psychiatric departments and related facilities. Haloperidol was used in 67% cases for the treatment of delirium. Ninety-seven per cent of facilities considered haloperidol as the drug of first choice, while 57% thought this drug had few side-effects and was easy to use. However, because the use of this drug is not covered by health insurance in Japan, its use is limited. We expect that this study on medication for the treatment of delirium will be a first step in increasing the approved indications for drugs used for the treatment of delirium, and to reduce off-label use.

Abstract
Delirium is a common and potentially preventable and reversible cause of functional disability, morbidity, mortality, and increased health care use among elderly individuals. Much has been learned about delirium in the past decade. Highlighted in this article are recent advances in the diagnosis of delirium, delirium in long-term care, use of health care resources, outcomes of delirium, etiologies, and interventions to prevent and treat delirium. Suggestions for future research also are proposed.
