Abstract
Background Delirium is a common symptom of heart failure (HF) and is associated with increased mortality, prolonged hospital stays, and heightened medical costs. The impact of delirium on the prognosis of HF patients is currently controversial. Therefore, we conducted a meta-analysis to evaluate the prognostic significance of delirium in HF. Methods Relevant articles were systematically searched in PubMed, Cochrane Library, Web of Science, and Embase based on the PRISMA guidelines. Studies that reported mortality and hospitalization-related outcomes in HF patients with or without delirium using raw or adjusted hazard ratio (HR) and odds ratio (OD) were included. Meta-analysis was then performed to evaluate the effect of delirium in HF patients. Outcomes of interest were all-cause mortality and events of the hospitalization. Results Of the 1,501 studies identified, 7 eligible studies involving 12,830,390 HF patients (6,322,846 males and 6,507,544 females) were included in the meta-analysis. There were 91,640 patients with delirium (0.71%) and 12,738,750 patients without delirium (99.28%). HF patients with delirium had higher OR for in-hospital mortality (1.95, 95% CI = 1.30-2.91, P = 0.135), higher pooled HR for 90-day mortality (2.64, 95% CI = 1.06-1.56, P = 0.215), higher pooled HR for 1-year mortality (2.08, 95% CI = 1.34-3.22, P = 0.004), and higher pooled HR for 30-day readmission rate (4.15, 95% CI = 2.85-6.04, P = 0.831) than those without delirium. Conclusion Current evidence suggests that combined delirium increases the risk of HF-related mortality and hospitalization-related outcomes in patients with HF. However, more research is needed to assess the impact of delirium on the prognosis of HF patients.

Abstract
BackgroundThe Nursing Delirium Screening Scale (Nu-DESC) is an effective instrument for assessing postoperative delirium (POD). This study translated the Nu-DESC into Thai (“Nu-DESC-Thai”), validated it, and compared its accuracy with the Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5).MethodsThe translation process followed the International Society for Pharmacoeconomics Outcome Research guidelines. Recruited participants were ≥ 70 years old, fluent in Thai, and scheduled for surgery. The exclusion criteria were cancellation or postponement of an operation, severe visual or auditory impairment, and patients with a Richmond Agitation Sedation Scale score of –4 or less before delirium assessment. Post-anesthesia care unit (PACU) nurses and residents on wards each used the Nu-DESC to assess delirium in 70 participants (i.e., 140 assessments) after the operation and after patient arrival at wards, respectively. Geriatricians confirmed the diagnoses using video observations and direct patient contact.ResultsThe participants’ mean age was 76.5 ± 4.6 years. The sensitivity and specificity of the Nu-DESC-Thai at a threshold of ≥ 2 were 55% (95% CI, 31.5–76.9%) and 90.8% (84.2–95.3%), respectively, with an area under a receiver operating characteristic curve (AUC) of 0.73. At a threshold of ≥ 1, the sensitivity and specificity were 85% (62.1–96.8%) and 71.7% (62.7–79.5%), respectively (AUC, 0.78). Adding 1 point for failing backward-digit counting (30–1) to the Nu-DESC-Thai and screening at a threshold of ≥ 2 increased its sensitivity to 85% (62.1–96.8%) with the same specificity of 90.8% (84.2–95.3%).ConclusionThe Nu-DESC-Thai showed good validity and reliability for postoperative use. Its sensitivity was inadequate at a cutoff ≥ 2. However, the sensitivity improved when the threshold was ≥ 1 or with the addition of backward counting to Nu-DESC-Thai and screening at a threshold of ≥ 2.

Abstract
OBJECTIVES Pediatric delirium is a neuropsychiatric disorder with disrupted cerebral functioning due to underlying disease and/or critical care treatment. Pediatric delirium can be classified as hypoactive, hyperactive, and mixed. This systematic review was conducted to estimate the pooled prevalence of pediatric delirium using validated assessment tools in children (Cornell Assessment of Pediatric Delirium, Pediatric Confusion Assessment Method for the ICU, PreSchool Confusion Assessment Method for the ICU, Pediatric Confusion Assessment Method for the ICU Severity Scale, and Sophia Observation Withdrawal Symptoms Pediatric Delirium scale), identify modifiable and nonmodifiable risk factors, and explore the association of pediatric delirium with clinical outcomes. DATA SOURCES A systematic search of PubMed, EMBASE, and CINAHL databases was undertaken for full articles pertaining to pediatric delirium prevalence. STUDY SELECTION No language or date barriers were set. Studies were included where the following eligibility criteria were met: study design aimed to estimate pediatric delirium prevalence arising from treatment in the intensive care setting, using a validated tool. Only randomized controlled trials, cross-sectional studies, or cohort studies allowing an estimate of the prevalence of pediatric delirium were included. DATA EXTRACTION Data were extracted by the primary researcher (D.S.) and accuracy checked by coauthors. DATA SYNTHESIS A narrative synthesis and pooled prevalence meta-analysis were undertaken. CONCLUSIONS Pediatric delirium, as determined by the Cornell Assessment of Pediatric Delirium score, is estimated to occur in 34% of critical care admissions. Eight of 11 studies reporting on subtype identified hypoactive delirium as most prevalent (46-81%) with each of the three remaining reporting either hyperactive (44%), mixed (57%), or equal percentages of hypoactive and mixed delirium (43%) as most prevalent. The development of pediatric delirium is associated with cumulative doses of benzodiazepines, opioids, the number of sedative classes used, deep sedation, and cardiothoracic surgery. Increased time mechanically ventilated, length of stay, mortality, healthcare costs, and associations with decreased quality of life after discharge were also found. Multi-institutional and longitudinal studies are required to better determine the natural history, true prevalence, long-term outcomes, management strategies, and financial implications of pediatric delirium.

Abstract
Introduction Given the aging population and the high prevalence of cognitive impairment in older hospitalized patients, it is essential to provide good fundamental care to these vulnerable patients, who easily might be affected by poor outcomes as delirium. Risk factors for delirium are, for example, cognitive impairment, old age, pain, and sleep deprivation. Different symptoms are often unidentified in hospitals, and associated with poor well-being, but this is rarely studied in older patients with cognitive impairment. The study aim was to examine symptoms and sense of well-being in older hospitalized patients with cognitive impairment, as self-reported and reported in patient records. Methods Exploratory quantitative subgroup (n = 25) analysis of a point-prevalence study (n = 210). Inclusion criteria were age ≥65, and cognitive impairment. Data were collected through structured interviews, validated instruments, and patient records. Associations between well-being and symptoms, and concordance between the occurrence of self-reported symptoms and symptoms reported in patient records were analyzed. Results The patients reported severe and distressing symptoms that were sparsely reported (14%) in their records. As well were cognitive impairment, and the patients' own descriptions of their well-being. Some symptoms and the total symptom burden were associated with poor well-being. Discussion/Conclusion To our knowledge, this hypothesis-generating study is one of few studies that describe both symptoms and well-being as self-reported and reported in patient records, in vulnerable patients due to old age, cognitive impairment, and hospitalization. Despite the limited sample size, the results indicate that symptoms were more insufficient alleviated in these patients compared to patients with normal cognitive function in other studies. To our knowledge, this has not been shown previously. Additionally, patients' own experiences were sparsely reported in their records. A larger sample size and longitudinal design has the potential to determine if symptom alleviation differs between patients with and without cognitive impairment, and if a total symptom burden increases the risk of poor outcomes as delirium in vulnerable patients.

Abstract
Malnutrition is common among older adults in health-care settings and is associated with decreased quality of life (QoL). The present study aimed to investigate the effect on health-related QoL (HRQoL) among older adults after 6 months of treatment with individual dietary advice (DA) and/or oral nutritional supplements (ONS), utilising 409 patients included in a multicentre randomised controlled trial of patients ≥ 65 years old, stratified according to nutrition status (malnourished/at risk of malnutrition), admitted to hospital in Sweden 2010-2014. Patients were randomised into four arms: DA, ONS, DA + ONS or routine care (control). The intervention started at discharge from hospital, with HRQoL measured using European QoL five-dimension, three-level (EQ-5D-3L) and European QoL-visual analogue scale (EQ-VAS) at baseline and at 6-month, 1-year and 3-year follow-ups. Data were analysed using the Kruskal-Wallis test and multiple linear regression. Overall, HRQoL increased from baseline to follow-ups, although the magnitude of change in EQ-5D-3L did not differ significantly between the four arms in any of the nutrition groups. However, a significant difference was observed for change in EQ-VAS from baseline to 6-month follow-up in the malnourished group, with mean changes of 22·4 and -3·4 points for the ONS and control groups, respectively (P = 0·009). In the multiple linear regression analyses, participants in the ONS arm had 27·5, 34·4 and 38·8 points larger increases in EQ-VAS from baseline to the 6-month (P = 0·011), 1-year (P = 0·007) and 3-year (P = 0·032), respectively, follow-ups than the control group. The use of ONS improved subjectively assessed HRQoL in these malnourished older adults.

Abstract
Objectives: The study aimed to investigate the effect on survival after 6 months of treatment involving individual dietary advice and oral nutritional supplements in older malnourished adults after discharge from hospital.Methods: This multicentre randomised controlled trial included 671 patients aged 65 years who were malnourished or at risk of malnutrition when admitted to hospital between 2010 and 2014, and followed up after 8.2 years (median 4.1 years). Patients were randomised to receive dietary advice or oral nutritional supplements, separate or in combination, or routine care. The intervention started at discharge from the hospital and continued for 6 months, with survival being the main outcome measure.Results: During the follow-up period 398 (59.3%) participants died. At follow-up, the survival rates were 36.9% for dietary advice, 42.4% for oral nutritional supplements, 40.2% for dietary advice combined with oral nutritional supplements, and 43.3% for the control group (log-rank test p = 0.762). After stratifying the participants according to nutritional status, survival still did not differ significantly between the treatment arms (log-rank test p = 0.480 and p = 0.298 for the 506 participants at risk of malnutrition and the 165 malnourished participants, respectively).Conclusions: Oral nutritional supplements with or without dietary advice, or dietary advice alone, do not improve the survival of malnourished older adults. These results do not support the routine use of supplements in older malnourished adults, provided that survival is the aim of the treatment.Trial registration: ClinicalTrials.gov with ID: NCT01057914.

Abstract
Supplemental Digital Content is available in the text. Objectives: To characterize the risk of long-term cognitive impairment associated with delirium in acute neurologic injury patients. Design: We analyzed a 10-year cohort of adult acute neurologic injury patients (stroke and traumatic brain injury) without preexisting mild cognitive impairment or dementia, utilizing administrative databases. Patients were followed for in-hospital delirium and mild cognitive impairment or dementia. We report incidence and adjusted hazard ratios for mild cognitive impairment or dementia associated with delirium. Subgroups analyzed include acute neurologic injury categories, dementia subtypes, repeated delirium exposure, and age strata. Setting: We used state emergency department and state inpatient databases for New York, Florida, and California. All visits are included in the databases regardless of payer status. Patients: We included adult patients with diagnosis of stroke and traumatic brain injury as acute neurologic injury. Patients with preexisting mild cognitive impairment or dementia were excluded. Interventions: None. Measurements and Main Results: Among 911,380 acute neurologic injury patients, 5.2% were diagnosed with delirium. Mild cognitive impairment or dementia incidence among delirium patients was approximately twice that of nondelirium patients. In adjusted models, risk of mild cognitive impairment or dementia was higher among patients with delirium (adjusted hazard ratio, 1.58). Increased risk was observed across all subgroups including patients less than or equal to 55 years old. Conclusions: Identification, management, and prevention of in-hospital delirium could potentially improve long-term cognitive outcomes in acute neurologic injury patients.

Abstract
BACKGROUND Impaired cognition is a major risk factor for perioperative delirium. It is essential to provide good pain control in patients with hip fractures and especially important in patients with severely impaired cognitive status, as they receive less pain medication, have poorer mobility, poorer quality of life and higher mortality than patients with intact cognition. The purpose of this study was to examine the association between preoperative pain management with nerve blocks and cognitive status in patients with hip fractures during the perioperative period. METHODS One hundred and twenty-seven patients with hip fractures participating in a double-blind, randomised, controlled trial were included in this study. At hospital admission, a low-dose fascia iliaca compartment block (FICB) was administered as a supplement to regular analgesia. Cognitive status was registered on arrival at hospital before FICB and on the first postoperative day using the Short Portable Mental Status Questionnaire. RESULTS Changes in cognitive status from arrival at hospital to the first postoperative day showed a positive, albeit not significant, trend in favour of the intervention group. The results also showed that patients with no or a moderate cognitive impairment received 50% more prehospital pain medication than patients with a severe cognitive impairment. FICB was well tolerated in patients with hip fractures. CONCLUSION Fascia iliaca compartment block given to patients with hip fractures did not affect cognitive status in this study. Patients with a cognitive impairment may receive inadequate pain relief after hip fracture and this discrimination needs to be addressed in further studies.

Abstract
Background Delirium is one of the most common complications among elderly hospitalized patients, postoperative patients and patients on intensive care units with a prevalence between 11 and 80%. Delirium is associated with higher morbidity and mortality. Reliable instruments are required to detect delirium at an early time point. The Nursing-Delirium Screening Scale (Nu-DESC) is a screening tool with high sensitivity and good specificity. However, there is currently no official translation after ISPOR guidelines of any Danish delirium assessment tools available. Thereby hampering the implementation of 2017 ESA-Guidelines on postoperative Delirium in the clinical routine. The aim of this study is to provide an official translation and evaluation of the Nu-DESC into Danish following the ISPOR process. Methods The Nu-DESC was translated after International Society for Pharmacoecomonics and Outcome Research (ISPOR) guidelines to Danish after permission of the original author, and is evaluated by medical staff and finally approved by the original author. Results All steps of the ISPOR guideline were consecutively followed, without any major problems. The evaluation of the Nu-DESC DK regarding its intelligibility and feasibility showed no statistically significant differences between nurses and medical doctors ratings. The translation was authorized and approved by the original author. Conclusion This study provides the Nu-DESC DK, an official Danish delirium screening instrument, which can detect all psychomotor types of delirium.

Abstract
INTRODUCTION Delirium is one of the most common complications after cardiac surgery in the elderly. Future studies aimed at preventing postoperative delirium will need an accurate estimate of incidence. However, there are no available systematic reviews on the incidence, and reports of incidence of postoperative delirium after a cardiac operation vary widely with significant heterogeneity. Therefore, we aim to perform a systematic review and meta-analysis to determine the most accurate incidence possible of postoperative delirium in individuals aged >65 years after cardiac surgery. METHODS AND ANALYSES We will undertake a comprehensive literature search among PubMed, EMBASE, the Cochrane Library, PsycINFO and CINAHL, from their inception to January 2017. Prospective cohort and cross sectional studies that described the incidence of delirium will be eligible for inclusion. The primary outcome will be the incidence of delirium. Risk of bias and methodological quality for the included studies will be assessed using a risk of bias tool for prevalence studies and the Cochrane guidelines. Heterogeneity of the estimates across studies will be assessed. Incidence data will be pooled by selective or emergency surgery. This systematic review will be reported according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA). ETHICS AND DISSEMINATION This proposed systematic review and meta-analysis is based on published data, and thus there is no requirement for ethics approval. The study will provide an up to date and accurate incidence of postoperative delirium among the older population after cardiac surgery, which is necessary for future research in this area. The findings of this study will be presented at conferences and disseminated through publication in a peer reviewed journal. TRIAL REGISTRATION NUMBER CRD42016047773.

Abstract
INTRODUCTION Femoral neck fracture (FNF) is a devastating injury with serious medical and social consequences. One-third of these patients have some degree of impaired cognitive status. Despite this, a high proportion of hip fracture trials exclude patients with cognitive impairment (CI). We aimed to evaluate whether moderate to severe CI could predict walking ability, quality of life, functional outcome, reoperations and mortality in elderly patients with displaced FNF treated with hemiarthroplasty (HA). METHODS This cohort study included a consecutive series of 188 patients treated with HA for a displaced FNF. Patients were assessed for estimated preoperative and 1 year postoperatively with regard to walking ability, cognitive status, quality of life with EQ-5D and hip function with Harris hip score. RESULTS There were 188 patients who met the inclusion criteria. A total of 130 patients were in the control group, and 58 were in the CI group. At 1-year follow-up, 31 patients (24%) had died in the control group and 22 patients (38%) had died in the cognitive impaired group. This difference in reoperation and mortality rate was statistically significant (log-rank test, p = 0.016). The CI had a significantly higher incidence of being non-walker (28 vs. 4%, OR 9.2, p = 0.001). The EQ-5D was higher in the control group, while the Harris hip score was comparable in the two groups. CONCLUSIONS Moderate to severe CI was associated with a high incidence of non-walking ability, worse quality of life, high mortality and re-operation rate after femoral neck fractures treated with HA.

Abstract
BACKGROUND The ability to determine which episodes of delirium are likely to lead to poor clinical outcomes has remained a major area of challenge. OBJECTIVE To quantify delirium severity and course over an entire hospitalization using several measures, and to evaluate their predictive validity for 30- and 90-day outcomes post-discharge. DESIGN Two prospective cohort studies. PARTICIPANTS Analysis was conducted in two independent cohorts of adult patients aged ≥70. MAIN MEASURES Nine delirium episode severity measures were examined: (1) measures reflecting delirium intensity (peak Confusion Assessment Method-Severity [CAM-S] and mean CAM-S score), (2) a measure reflecting delirium intensity and duration (sum of all CAM-S scores, sum of all CAM-S scores on delirium days only, peak CAM-S score x days with delirium), (3) measures requiring information on delirium duration and delirium at discharge (total number of delirium days, percentage of delirium days, delirium at discharge), and (4) a measure of cognitive change. Associations of the delirium episode severity measures with 30- and 90-day post-hospital outcomes (death, nursing home placement, and readmission) relevant to delirium were examined. KEY RESULTS The delirium episode severity measure that required information on both delirium intensity and duration (sum of all CAM-S scores) was the most strongly associated with 30- and 90-day post-hospital outcomes. Using this measure, the relative risk [95 % confidence interval] for death at 30-days increased across levels of sum of all CAM-S scores from 1.0 (referent) to 2.1 [0.8, 5.4] for 'low,' to 2.9 [1.2, 7.1] for 'moderate,' to 6.4 [2.9, 14.0] for 'high' (p for trend <.01). CONCLUSIONS The delirium episode severity measure that included both intensity and duration had the strongest association with important post-hospital outcomes.

Abstract
OBJECTIVES Delirium is common neuropsychiatric condition among elderly inpatients. The clock drawing test (CDT) has been used widely as bedside screening tool in assessing cognitive impairment in elderly people. Previous studies which evaluate its usefulness in delirium reported conflicting results. The objective of this study was to evaluate the utility of CDT to detect delirium in elderly medical patients. METHOD Prospective, observational, longitudinal study. All acute medical admissions 70 years of age and above were approached within 72 hours of admission for recruitment. Patients eligible for inclusion were assessed four times, twice weekly during admission. Assessment included Confusion Assessment Method (CAM), Delirium Rating Scale (DRS-98R), Montreal Cognitive Assessment (MoCA), Acute Physiology and Chronic Health Evaluation II (APACHE) II, and CDT. Data was analysed using a linear mixed effect model. RESULTS Three hundred and twenty-three assessments with the CDT were performed on 200 subjects (50% male, mean age 81.13; standard deviation: 6.45). The overall rate of delirium (CAM+) during hospitalisation was 23%. There was a significant negative correlation between the CDT and DRS-R98 scores (Pearson correlation r = -0.618, p < 0.001), CDT and CAM (Spearman's rho = -0.402, p < 0.001) and CDT and total MoCA score (Pearson's r = 0.767, p < 0.001). However, when the data were analysed longitudinally controlling for all the factors, we found that cognitive function and age were significant factors associated with CDT scores (p < .0001): neither the presence nor the severity of delirium had an additional significant effect on the CDT. CONCLUSION CDT score reflects cognitive impairment, independently of the presence or severity of delirium. The CDT is not a suitable test for delirium in hospitalised elderly patients.

Abstract
Delirium in the intensive care unit is prevalent and a topic of high interest. Although it has been studied a great deal, screening, prevention, and management remain difficult. There are many causes of delirium and equally as many approaches to prevention and treatment. Two case studies sharing the challenges and successes of education, prevention, and treatment of delirium are presented in the context of complex adaptive systems.

Abstract
CONTEXT Delirium is a common, distressing neuropsychiatric complication for patients in palliative care settings, where the need to minimize burden yet accurately assess delirium is hugely challenging. OBJECTIVES This review focused on the optimal clinical and research application of delirium assessment tools and methods in palliative care settings. METHODS In addition to multidisciplinary input from delirium researchers and other relevant stakeholders at an international meeting, we searched PubMed (1990-2012) and relevant reference lists to identify delirium assessment tools used either exclusively or partly in the context of palliative care. RESULTS Of the 26 delirium scales identified, we selected six for in-depth review: three screening tools, two severity measures, and one research tool for neuropsychological assessment of delirium. These tools differed regarding intended use, ease of use, training requirements, psychometric properties, and validation in or suitability for palliative care populations. The Nursing Delirium Screening Scale, Single Question in Delirium, or Confusion Assessment Method, ideally with a brief attention test, can effectively screen for delirium. Favoring inclusivity, use of Diagnostic and Statistical Manual of Mental Disorders-IV criteria gives the best results for delirium diagnosis. The Revised Delirium Rating Scale and the Memorial Delirium Assessment Scale are the best available options for monitoring severity, and the Cognitive Test for Delirium provides detailed neuropsychological assessment for research purposes. CONCLUSION Given the unique characteristics of patients in palliative care settings, further contextually sensitive studies of delirium assessment are required in this population.

Abstract
OBJECTIVE To determine validity and reliability of the Cornell Assessment of Pediatric Delirium, a rapid observational screening tool. DESIGN Double-blinded assessments were performed with the Cornell Assessment of Pediatric Delirium completed by nursing staff in the PICU. These ratings were compared with an assessment by consultation liaison child psychiatrist using the Diagnostic and Statistical Manual IV criteria as the "gold standard" for diagnosis of delirium. An initial series of duplicate Cornell Assessment of Pediatric Delirium assessments were performed in blinded fashion to assess interrater reliability. Nurses recorded the time required to complete the Cornell Assessment of Pediatric Delirium screen. SETTING Twenty-bed general PICU in a major urban academic medical center over a 10-week period, March-May 2012. PATIENTS One hundred eleven patients stratified over ages ranging from 0 to 21 years and across developmental levels. INTERVENTION Two hundred forty-eight paired assessments completed. MEASUREMENTS AND MAIN RESULTS The Cornell Assessment of Pediatric Delirium had an overall sensitivity of 94.1% (95% CI, 83.8-98.8%) and specificity of 79.2% (95% CI, 73.5-84.9%). Overall Cronbach's α of 0.90 was observed, with a range of 0.87-0.90 for each of the eight items, indicating good internal consistency. A scoring cut point of 9 demonstrated good interrater reliability of the Cornell Assessment of Pediatric Delirium when comparing results of the screen between nurses (overall κ = 0.94; item range κ = 0.68-0.78). In patients without significant developmental delay, sensitivity was 92.0% (95% CI, 85.7-98.3%) and specificity was 86.5% (95% CI, 75.4-97.6%). In developmentally delayed children, the Cornell Assessment of Pediatric Delirium showed decreased specificity of 51.2% (95% CI, 24.7-77.8%) but sensitivity remained high at 96.2% (95% CI, 86.5-100%). The Cornell Assessment of Pediatric Delirium takes less than 2 minutes to complete. CONCLUSIONS With an overall prevalence rate of 20.6% in our study population, delirium is a common problem in pediatric critical care. The Cornell Assessment of Pediatric Delirium is a valid, rapid, observational nursing screen that is urgently needed for the detection of delirium in PICU settings.

Abstract
OBJECTIVES To compare the outcome of internal fixation (IF) versus a cemented hemiarthroplasty (HA) in patients with a displaced femoral neck fracture and a severe cognitive dysfunction. DESIGN A prospective randomized controlled trial. SETTING A tertiary care university hospital. PATIENTS Sixty patients with a displaced femoral neck fracture were randomized to IF (n = 30) or HA (n = 30). All patients suffered from severe cognitive dysfunction but were able to walk before the fracture. INTERVENTION IF using 2 cannulated screws or HA using a cemented Exeter unipolar arthroplasty. MAIN OUTCOME MEASUREMENTS Patients were reviewed at 4, 12, and 24 months after the fracture. Outcome assessments included complications, reoperations, hip function (Charnley score), and health-related quality of life (EQ-5Dindex score). RESULTS A total of 8 patients were reoperated (14%); 7 in the IF group and 1 in the HA group. The EQ-5Dindex score at the follow-ups were generally lower in the IF group compared with the HA group with a significant difference at 12 months (P = 0.03). No difference was seen in hip function, general complications, or mortality between the groups. CONCLUSIONS HA seems to provide a safe option with better health-related quality of life and less risk for reoperations compared with IF for these patients. LEVEL OF EVIDENCE Therapeutic level II.

Abstract
BACKGROUND Delirium is a serious neuropsychiatric syndrome frequently experienced by palliative care inpatients. This syndrome is under-recognized by clinicians. While screening increases recognition, it is not a routine practice. AIM AND DESIGN This systematic review aims to examine methods, quality, and results of delirium prevalence and incidence studies in palliative care inpatient populations and discuss implications for delirium screening. DATA SOURCES A systematic search of the literature identified prospective studies reporting on delirium prevalence and/or incidence in inpatient palliative care adult populations from 1980 to 2012. Papers not in English or those reporting the occurrence of symptoms not specifically identified as delirium were excluded. RESULTS Of the eight included studies, the majority (98.9%) involved participants (1079) with advanced cancer. Eight different screening and assessment tools were used. Delirium incidence ranged from 3% to 45%, while delirium prevalence varied, with a range of: 13.3%-42.3% at admission, 26%-62% during admission, and increasing to 58.8%-88% in the weeks or hours preceding death. Studies that used the Diagnostic and Statistical Manual-Fourth Edition reported higher prevalence (42%-88%) and incidence (40.2%-45%), while incidence rates were higher in studies that screened participants at least daily (32.8%-45%). Hypoactive delirium was the most prevalent delirium subtype (68%-86% of cases). CONCLUSION The prevalence and incidence of delirium in palliative care inpatient settings supports the need for screening. However, there is limited consensus on assessment measures or knowledge of implications of delirium screening for inpatients and families. Further research is required to develop standardized methods of delirium screening, assessment, and management that are acceptable to inpatients and families.

Abstract
Delirium is the most common neuropsychiatric complication seen in patients with cancer, and it is associated with significant morbidity and mortality. Increased health care costs, prolonged hospital stays, and long-term cognitive decline are other well-recognized adverse outcomes of delirium. Improved recognition of delirium and early treatment are important in diminishing such morbidity. There has been an increasing number of studies published in the literature over the last 10 years regarding delirium treatment as well as prevention. Antipsychotics, cholinesterase inhibitors, and alpha-2 agonists are the three groups of medications that have been studied in randomized controlled trials in different patient populations. In patients with cancer, the evidence is most clearly supportive of short-term, low-dose use of antipsychotics for controlling the symptoms of delirium, with close monitoring for possible adverse effects, especially in older patients with multiple medical comorbidities. Nonpharmacologic interventions also appear to have a beneficial role in the treatment of patients with cancer who have or are at risk for delirium. This article presents evidence-based recommendations based on the results of pharmacologic and nonpharmacologic studies of the treatment and prevention of delirium.

Abstract
UNLABELLED Surgical pain in patients with documented opioid-induced delirium can be difficult to treat. We present a case of a patient undergoing laparoscopic hemicolectomy effectively treated with an opioid-free, alpha-2 adrenoreceptor agonist analgesic regimen. CASE REPORT A 21-year-old woman with persistent abdominal pain presented to the operating room for laparoscopic hemicolectomy for redundant right colon. Her medical history included a recently diagnosed postoperative opioid-induced delirium. Epidural infusion with local anesthetic offered partial pain relief with sensory levels of T9-L2. With the addition of dexmedetomidine infusion in the immediate postoperative period, the patient was comfortable with pain scores of 1 to 2/10 on Numerical Rating Scale (NRS). On postoperative day 1, the infusion was discontinued and the clonidine, 12 μg/hours was added to the epidural bupivacaine. With increased sedation 48 hours later, neuraxial clonidine was discontinued in favor to transdermal clonidine 0.1 mg/week, which was maintained until hospital discharge. Pain scores were maintained at 2 to 3/10 on NRS for the next 3 days when increased abdominal distention because of abscess formation rendered a new surgical intervention. The analgesia for the exploratory laparoscopy was maintained using epidural clonidine and bupivacaine infusion as well as intravenous dexmedetomidine, which were maintained another 2 days. Pain scores remained minimal until discharged home 3 day later. DISCUSSION Nonopioid analgesic regimens are beneficial in patients at risk of postoperative cognitive dysfunction attributable to opioids. Successful postoperative analgesia was achieved in our patient by alternating various routes of administration of alpha-2 adrenoreceptor agonists.

Abstract
INTRODUCTION The aim of the study was to determine to what extent severe cognitive impairment impacts short-term rehabilitation outcomes of elderly patients with proximal hip fracture. MATERIAL AND METHODS A total of 337 community-dwelling elderly patients with acute hip fracture were observed during a 12-month period at a major teaching hospital in Serbia. Cognitive status was assessed at admission with the Short Portable Mental Status Questionnaire (SPMSQ). Outcome after 4 months was analysed with respect to presence of severe cognitive impairment, defined as an SPMSQ score of < 3. Outcome assessment included presence of postoperative complications, absolute motor Functional Independence Measure (FIM) gain, Activities of Daily Living index (ADL), Instrumental Activities of Daily Living score (IADL), and walking ability. RESULTS An SPMSQ score of < 3 was observed in 36 patients (10.7%) with acute hip fracture. Patients with an SPMSQ score of < 3 achieved worse short-term outcomes regarding all observed variables. However, cognitive status was found to be an independent predictor only with respect to mortality at 4 months (odds ratio (OR) = 0.969, 95% confidence interval (CI) = 0.947-0.992, p = 0.009). In contrast, pre-fracture motor FIM independently predicted mortality (OR = 2.982, 95% CI = 1.271-7.000, p = 0.012), and preserved walking ability at 4 months follow-up (OR = 0.945, 95% CI = 0.912-0.980, p = 0.002). Correspondingly, pre-fracture ADL was an independent predictor of absolute motor FIM gain at 4 months follow-up (OR = 0.175, 95% CI = 0.405-11.426, p = 0.035). CONCLUSIONS Failure to consider functional status prior to fracture might overestimate the impact of cognitive status on functional outcome of hip fracture patients.

Abstract
BACKGROUND AND AIMS Comprehensive geriatric assessment (CGA) may benefit frail or chronically ill patients in the emergency department (ED), but take too much time to be performed routinely in ED. An alternative approach is to use first a screening tool to detect high-risk patients and then perform CGA in these patients only. This systematic review focuses on the use and value of CGA in ED for evaluation of older patients and its influence on adverse outcomes. This approach is compared with an alternative one using existing screening tools, validated in ED, to detect high-risk patients needing subsequent CGA. This review ends by suggesting a short assessment of CGA to be used in ED and ways to improve home discharge management from ED. METHODS A systematic English Medline literature search was conducted in December 2009, with no date limit with the following Medical Subject Heading (MeSH) terms: "Frail Elderly", "Health Services for Aged", "Community Health Nursing", "Emergency Service, Hospital", "Geriatric Assessment", "Patient Discharge", "Risk Assessment" and "Triage". RESULTS We selected 8 studies on CGA efficiency and 14 on screening tools. CGA in ED is efficient for decreasing functional decline, ED readmission and possibly nursing home admission in high-risk patients. As CGA takes too much time to be performed routinely in ED, validated screening tools can be applied to detect high-risk patients who will benefit most from CGA. CONCLUSIONS The selected studies demonstrated that screening of high-risk patients is more efficient than age-based screening, and that CGA performed in ED, followed by appropriate interventions, improves outcomes.

Abstract
BACKGROUND Major depression and delirium are prevalent, underrecognized, and undertreated in hospice and palliative care settings. Furthermore, they are both associated with significant morbidity and mortality. OBJECTIVE A screening study of patients receiving inpatient hospice care was conducted in order to determine the ease of screening for depression and delirium in patients with advanced, life-threatening illnesses by hospice social workers and nurses, respectively. METHODS A two-question depression screening tool was administered to 20 consecutive patients on admission to a hospice general inpatient care center by social work staff during their initial assessment. A delirium-screening tool was administered daily to 22 consecutive patients admitted to the ICC daily by nursing staff. Screening results were collected, as were patient and staff feelings about the burden of the screening process. RESULTS Of the 20 patients screened on admission for depression by social work, 70% (14/20) screened positive. Of the 22 patients screened daily for delirium by nursing, 64% (14/22) screened positive at least once during their admission. Screening for both conditions was considered relatively easy to accomplish by the hospice staff. There were no significant associations between a positive screen of depression or delirium and patient gender, age, ethnicity, terminal diagnosis, or marital status. DISCUSSION These results support the notion that depression and delirium are very common in hospice inpatients, and that screening for both is relatively easy and practical for hospice clinicians to conduct.

Abstract
Mechanical ventilation is a common therapeutic modality required for the management of patients unable to maintain adequate intrinsic ventilation and oxygenation. Mechanical ventilators can be found within various hospital and nonhospital environments (ie, nursing homes, skilled nursing facilities, and patient’s home residence), but these devices generally require the skill of a multidisciplinary health care team to optimize therapeutic outcomes. Unfortunately, pharmacists have been excluded in the discussion of mechanical ventilation since this therapeutic modality may be perceived as irrelevant to drug utilization and the usual scope of practice of a hospital pharmacist. However, the pharmacist provides a crucial role as a member of the multidisciplinary team in the management of the mechanically ventilated patient by verifying accuracy of prescribed medications, providing recommendations of alternative drug selections, monitoring for drug and disease interactions, assisting in the development of institutional weaning protocols, and providing quality assessment of drug utilization. Pharmacists may be intimidated by the introduction of advanced ventilator microprocessor technology, but understanding and integrating ventilator management with the pharmacotherapeutic needs of the patient will ultimately help the pharmacist be a better qualified and respected practitioner. The goal of this article is to assist the pharmacy practitioner with a better understanding of mechanical ventilation and to apply this information to improve delivery of pharmaceutical care.

Abstract
There is a need for generalist- and specialist-level palliative care clinicians proficient in symptom management and care coordination. Major factors contributing to this need include changed disease processes and trajectories, improved medical techniques and diagnostic testing, successful screening for chronic conditions, and drugs that often prolong life. The rapid progressive illnesses and deaths that plagued the first half of the twentieth century have been replaced in the twenty-first century by increased survival rates. Conditions that require ongoing medical care beyond a year define the current chronic illness population. Long years of survival are often accompanied by a reduced quality of life that requires more medical and nursing care and longer home care. This article reviews the management of selected symptoms in palliative and end of life care.

Abstract
OBJECTIVES Delirium is a common neuropsychiatric condition with many adverse outcomes in elderly populations including death. Despite this, it is often misdiagnosed and mistreated. A number of scales can be used to detect delirium. We review scales that have been used in delirium studies and report their psychometric properties. METHOD An extensive MEDLINE database search and subsequent examination of reference lists was conducted to identify the various delirium scales that have been designed, primarily for use in the elderly. RESULTS Twenty-four scales were identified. Delirium instruments differed according to the classification system they were based on, length of time to administer, the rater and whether they were screening scales or measured symptom severity. The psychometric properties of each scale is reported. CONCLUSION A large number of scales exist, but not all are properly evaluated in terms of psychometric properties, and there is not unanimity about which scale is the best. However, a small number of scales may be considered already to be robust and useable: the CAM, the DRS, the MDAS and the NEECHAM.

Abstract
OBJECTIVE To review the research about psychostimulant effects on cognitive functions in end-of-life patients diagnosed with hypoactive delirium or cognitive disorders. METHOD The MEDLINE (1966-March 2008), Embase (1974-March 2008), PsycINFO (1806-March 2008), IPA (1970-March 2008), CINAHL (1982-March 2008), ISI Web of Science (1945-March 2008), Current Contents (March 2007-March 2008), Access Medicine (2001-March 2008), and ProQuest Dissertations & Theses (1980-March 2008) databases were searched with keywords related to delirium, cognition, psychostimulants, and palliative care for French or English articles in a dementia-free and hyperactive delirium-free end-of-life population. Cognitive functions had to be assessed before and after initiation of the psychostimulant treatment. Moreover, treatment had to be initiated after the onset of cognitive impairments. RESULTS A total of 173 studies were screened. Five studies on methylphenidate and 1 study on caffeine met inclusion criteria and were included in this review. Two studies were case reports, 2 were open-label trials, and 2 were double-blind, crossover randomized placebo-controlled trials. Three studies were conducted with hypoactive delirium patients and all studies were conducted in an advanced cancer patient population. CONCLUSIONS The reviewed studies support the use of methylphenidate to improve end-of-life patient cognitive functions, particularly in the case of hypoactive delirium. Caffeine seems to have beneficial effects on psychomotor activity. Further well-designed studies are needed to consolidate these findings.

Abstract
The purpose of this study was to evaluate the ability of the Dehydration Risk Appraisal Checklist (DRAC) to measure dehydration risk in nursing home (NH) residents. The DRAC includes items concerning health conditions, medications, fluid intake behaviors, and laboratory abnormalities that have been identified in the literature as risk factors for dehydration. Principal component factor analysis, known group comparisons, and multiple logistic regression were used to evaluate the criterion-related validity and reliability of the DRAC. After reducing the number of items on the DRAC on the basis of a correlation matrix, a single-factor solution with moderate internal consistency was supported. Further validity analysis demonstrated that NH residents with higher urine-specific gravity scored higher than those who had lower specific gravity. The psychometric properties of the DRAC indicate that it has potential in determining dehydration risk in NH residents. Future refinement of the instrument is also discussed.

Abstract
OBJECTIVES The purpose of this study was to collate all works relating to delirium and probable delirium in children and adolescents published since 1980. METHODS A systematic review of the literature in all languages published between 1980 and March 2009 was conducted. RESULTS The literature is limited to small case series and case reports including a total of 217 children or adolescents with definite delirium and a further 136 children and adolescents with "probable delirium." These articles, in addition to unsystematic reviews, overviews, editorials, journal commentaries, and pertinent book chapters, are discussed in relation to prevalence, predisposing and precipitating factors, phenomenology, residual psychopathology, mortality, management, and prevention of delirium in childhood and adolescence. CONCLUSIONS Delirium is an important but neglected disorder of childhood associated with significant morbidity and high mortality. Current clinical practice for management is based on slim empirical evidence.

Abstract
The psychosocial and psychiatric sequelae of cancer are highly prevalent, diverse, and challenging for clinicians to manage. A growing body of literature has generated methods for the reliable screening, assessment, and management of these sequelae, including the treatment of psychiatric disorders that may complicate the course of cancer. To meet the specific needs of this patient population, psycho-oncologists worldwide have begun to train more and more social workers, psychologists, and psychiatrists who can provide consultative services in support of the psychiatric care of cancer patients and their families at all stages of disease, including cancer survivorship. This review presents an overview of the history of psycho-oncology, common psychological responses to cancer, factors in adapting to cancer, epidemiology, the assessment and management of major psychiatric disorders in cancer patients, cancer-related fatigue, the cognitive effects of cancer and cancer treatment, issues related to the psychosocial care of families (including bereavement), and psychological issues for staff caring for cancer patients.

Abstract
OBJECTIVE To compare validity and reliability of three instruments for detection and assessment of delirium in intensive care unit (ICU) patients. Delirium in critically ill patients is associated with higher mortality, prolonged duration of ICU stay, and greater healthcare costs. Currently, there are several assessment tools available for detection of delirium, but only a few of these assessment systems are developed specifically to screen for delirium in ICU patients. DESIGN Prospective cohort study. SETTING ICU at a university hospital. PATIENTS A total of 156 surgical patients aged > or = 60 yrs consecutively admitted to the ICU, with a length of stay of at least 24 hrs. MEASUREMENTS AND MAIN RESULTS This study was approved by the institutional ethics committee. Trained staff members performed daily and independently the Confusion Assessment Method for the ICU (CAM-ICU), the Nursing Delirium Screening Scale (Nu-DESC), and the Delirium Detection Score (DDS). These evaluations were compared against the reference standard conducted by a delirium expert (blinded to the study), who used delirium criteria from the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). Of 156 patients, 63 (40%) were identified as delirious by the reference standard during the study. Using the CAM-ICU and the Nu-DESC, we measured comparable sensitivities (CAM-ICU, 81%; Nu-DESC, 83%). The specificity of the CAM-ICU was significantly higher than that of the Nu-DESC (96% vs. 81%, p < .01). In contrast, the DDS showed poor sensitivity (30%), whereas the specificity was significantly higher compared with the Nu-DESC (DDS, 91%; Nu-DESC, 81%, p < .05). The interrater reliability was "almost perfect" for the CAM-ICU (kappa = 0.89) and "substantial" for DDS and Nu-DESC (kappa = 0.79, 0.68). CONCLUSION The CAM-ICU showed the best validity of the evaluated scales to identify delirium in ICU patients. The Nu-DESC might be an alternative tool for detection of ICU delirium. The DDS should not be used as a screening tool.

Abstract
Delirium remains the most common and distressing neuropsychiatric complication in patients with advanced cancer. Delirium causes significant distress to patients and their families, and continues to be underdiagnosed and undertreated. The most frequent, consistent, and, at the same time, reversible etiology is drug-induced delirium resulting from opioids and other psychoactive medications. The objective of this narrative review is to outline the causes of delirium in advanced cancer, especially drug-induced delirium, and the diagnosis and management of opioid-induced neurotoxicity. The early symptoms and signs of delirium and the use of delirium-specific assessment tools for routine delirium screening and monitoring in clinical practice are summarized. Finally, management options are reviewed, including pharmacological symptomatic management and also the provision of counseling support to both patients and their families to minimize distress.

Abstract
BACKGROUND Delirium is an acute confusional state that is common, preventable, and life-threatening. OBJECTIVE The authors investigated the phenomenology of delirium severity as measured with the Memorial Delirium Assessment Scale among 441 older patients (age 65 and older) admitted with delirium in post-acute care. METHODS Using latent class analysis, they identified four classes of psychomotor-severity subtypes of delirium: 1) hypoactive/mild; 2) hypoactive/severe; 3) mixed, with hyperactive features/severe; and 4) normal/mild. RESULTS Among those with dementia (N=166), the hypoactive/mild class was associated with a higher risk of mortality. Among those without dementia (N=275), greater severity was associated with mortality, regardless of psychomotor features, when compared with the normal/mild class. CONCLUSION The data suggest that instruments measuring delirium severity and psychomotor features provide important prognostic information and should be integrated into the assessment of delirium.

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
Sleep deprivation and delirium are conditions commonly encountered in intensive care unit patients. Sleep in these patients is characterized by sleep fragmentation, an increase in light sleep, and a decrease of both slow wave sleep and rapid eye movement sleep. The most common types of delirium in this population are hypoactive and mixed-type. Knowledge about the mechanisms of sleep and delirium has evolved over time, but these phenomena are not yet well understood. What is known, however, is that different areas in the brainstem transmit information to the thalamus and cortex necessary for sleep-wake regulation. Delirium is related to an imbalance in the synthesis, release, and inactivation of some neurotransmitters, particularly acetylcholine and dopamine. The relationship between sleep deprivation and delirium has been studied for many years and has been viewed as reciprocal. The link between them may be ascribed to shared mechanisms. An imbalance in neurotransmitters as well as alteration of melatonin production may contribute to the pathogenesis of both phenomena. A better understanding of the mechanisms and factors that contribute to sleep deprivation and delirium can guide the development of new methods and models for prevention and treatment of these problems and consequently improve patient outcomes.

Abstract
OBJECTIVES To evaluate the impact of using different diagnostic criteria on prevalence rates of delirium and subsyndromal delirium (SSD) among demented long-term care (LTC) residents. DESIGN Descriptive study. SETTING LTC settings in Quebec City, Canada. PARTICIPANTS Participants were 155 individuals aged 65 and older, with dementia. MEASUREMENTS (1) Prevalence rates of delirium according to: (a) the Diagnostic and Statistical Manual of Mental Disorders (DSM-III, DSM-III-R, and DSM-IV) and (b) the Confusion Assessment Method (CAM) algorithms for definite and probable delirium; and (2) prevalence rates of SSD employing 2 definitions described in previous studies. RESULTS Prevalence rates of delirium according to each set of criteria were 26.5% for DSM-III; 29% for DSM-IV-TR; 41.3% for DSM-III-R; 45.8% for CAM algorithm for definite delirium; and 70.3% for CAM algorithm for probable delirium. A total of 109 subjects (70.3%) were identified as delirious consistent with at least one classification and 37 (23.9%) met all the sets of criteria considered. Prevalence rates for SSD were 75 (48.4%) and 78 (50.3%) depending on the definition employed. CONCLUSION Prevalence rates for delirium are much affected by the diagnostic formulations used. The use of DSM-IV-TR among this population could result in fewer cases being identified as delirious and thus compromise proper care for those individuals. Considering that SSD was prevalent among this population, a systematic implementation of protocols targeting risk factors of delirium might be beneficial among demented LTC residents.

Abstract
OBJECTIVES To examine the association between persistent delirium and 1-year mortality in newly admitted postacute care (PAC) facility patients with delirium who were followed regardless of residence. DESIGN Observational cohort study. SETTING Eight greater-Boston skilled nursing facilities specializing in PAC. PARTICIPANTS Four hundred twelve PAC patients with delirium at admission after an acute hospitalization. MEASUREMENTS Assessments were done at baseline and four follow-up times: 2, 4, 12, and 26 weeks. Delirium, defined using the Confusion Assessment Method, was assessed, as were factors used as covariates in analyses: age, sex, comorbidity, functional status, and dementia. The outcome was 1-year mortality determined according to the National Death Index and corroborated using medical record and proxy telephone interview. RESULTS Nearly one-third of subjects remained delirious at 6 months. Cumulative 1-year mortality was 39%. Independent of age, sex, comorbidity, functional status, and dementia, subjects with persistent delirium were 2.9 (95% confidence interval 51.9-4.4) times as likely to die during the 1-year follow-up as subjects whose delirium resolved. This association remained strong and significant in groups with and without dementia. Additionally, when delirium resolved, the risk of death diminished thereafter. CONCLUSION In patients who were delirious at the time of PAC admission, persistent delirium was a significant independent predictor of 1-year mortality.

Abstract
The Confusion Assessment Method (CAM) is widely used in the palliative care setting despite the fact that its performance in this population has not been validated. The aim of the study was to determine the sensitivity and specificity of the CAM when used by Non-Consultant Hospital Doctors (NCHDs) working in a specialist palliative care unit. A pilot phase was performed in which NCHDs received a 1-hour training session based on the original CAM training manual. 32 patients underwent 33 assessments in the pilot phase but the sensitivity of the CAM was only 0.5 (0.22-0.78) and specificity was 1.0 (0.81-1.0). An 'enhanced' training programme was devised that took place over two 1-hour sessions and involved case-based learning focused on the areas where the NCHDs were experiencing difficulty. 52 patients underwent 54 assessments in the main phase of the study and the performance of the CAM improved significantly. Sensitivity was 0.88 (0.62-0.98) and specificity was 1.0 (0.88-1.0). The results suggest that the CAM is a valid screening tool for delirium in the palliative care setting but its performance is dependent on the skill of the operator. NCHDs require a certain standard of training before becoming proficient in its use.

Abstract
OBJECTIVE The objective of this study is to provide an expert review of delirium in the context of palliative care. METHODS Based on a primary selection criterion, firstly, studies were included for review if the population studied either had a diagnosis of advanced cancer or was receiving palliative care; alternatively, in the absence of data derived from these populations, studies conducted in other populations were included. Secondly, from the studies meeting the primary selection criterion, we selected those that examined specific standard outcome measures. Thirdly, we selected studies and literature reviews that identified delirium research issues. RESULTS Delirium occurs commonly in the context of palliative care where it is likely to cause heightened distress for patients, carers, and families alike, and make interpretation of pain and other symptoms extremely difficult. There is a profound dearth of rigorous studies on delirium in this setting. Ambiguous terminology, varying definitions in internationally recognized classification systems, and failure to use validated assessment tools lead to wide-ranging incidence and prevalence of delirium episodes in such populations. Episodes are usually multifactorial in origin and may portend poor prognosis by preceding death in many cases. Despite this, many are often at least partially reversible with relatively low-burden interventions. The patient's disease status, previous quality of life, and prior expressed wishes regarding goals of care should all be taken into account. Antipsychotics are the pharmacotherapeutic agents most commonly used to control symptoms despite limited evidence either supporting their efficacy or examining their adverse event profile. Often, symptomatic control alone is indicated. In cases with refractory symptoms, deeper or "palliative" sedation may be required. CONCLUSION Further research is needed regarding delirium recognition, phenomenology, the development of low-burden instruments for assessment, family education, predictive models for reversibility, and evidence-based guidelines on the appropriate use of palliative sedation.
