Abstract
OBJECTIVE The Japanese Psycho-Oncology Society and the Japanese Association of Supportive Care in Cancer have recently revised the clinical practice guidelines for delirium in adult cancer patients. This article reports the process of developing the revised guidelines and summarizes the recommendations made. METHODS The guidelines were developed in accordance with the Medical Information Network Distribution Service creation procedures. The guideline development group, consisting of multi-disciplinary members, created three new clinical questions: non-pharmacological intervention and antipsychotics for the prevention of delirium and trazodone for the management of delirium. In addition, systematic reviews of nine existing clinical questions have been updated. Two independent reviewers reviewed the proposed articles. The certainty of evidence and the strength of the recommendations were graded using the grading system developed by the Medical Information Network Distribution Service, following the concept of The Grading of Recommendations Assessment, Development, and Evaluation system. The modified Delphi method was used to validate the recommended statements. RESULTS This article provides a compendium of the recommendations along with their rationales, as well as a short summary. CONCLUSIONS These revised guidelines will be useful for the prevention, assessment and management of delirium in adult cancer patients in Japan.

Abstract
BACKGROUND The increase in life expectancy worldwide has led to a larger population of older people, which in turn entails a rising prevalence of cancer. One of the main complications of cancer is delirium, especially in advanced stages. OBJECTIVE To determine which delirium screening instrument is the most accurate in older people with cancer. METHODS A systematic review was designed. A literature search was performed in MEDLINE, EBSCO and SCOPUS; additional records were identified by handsearching. Selection criteria were studies involving people with cancer and a mean sample age of 60 years or older, assessing delirium, and reporting the metric properties of the assessment instrument. Studies with post-surgical patients and substance abuse delirium were excluded. RESULTS From 2001 to 2021, 14 eligible studies evaluated 13 different assessment tools, reporting an incidence of delirium ranging from 14.3% to 68.3%. The Delirium Observation Screening Scale (DOSS) showed the best metric properties, followed by the Nursing Delirium Screening Scale (NuDESC), Confusion Assessment Method (CAM) and Memorial Delirium Assessment Scale (MDAS). Only two studies were considered to be at low risk of bias using the QUADAS-2 Tool. No study exclusively examined this population group. CONCLUSIONS Screening tools for delirium are heterogeneous for older people with cancer, and there is a need to analyze metric properties exclusively in the older population.

Abstract
INTRODUCTION Delirium is a common neuropsychiatric condition in the general hospital population. Thus, the goal of the present study is to extend the use of diagnostic tools for delirium by developing and validating a Mandarin version of the Memorial Delirium Assessment Scale (MDAS). METHODS Participants were sampled from two general Mackay Memorial Hospital locations in Taipei and Danshui. Board-certified psychiatrists assessed patients using the MDAS, confusion assessment method (CAM), and Mini-Mental State Examination (MMSE). Another consultation-liaison psychiatrist confirmed the diagnosis of delirium. We assessed the reliability and validity of the MDAS, and the receiver operating characteristic curve was used to determine the optimal cut-off point for identifying delirium. RESULTS Of the 61 patients assessed, 29 were diagnosed with delirium. The mean MDAS score was 16.7 for delirium patients and 4.1 for nondelirium patients. The MDAS has good internal consistency, with a Cronbach's alpha coefficient of 0.912. Interrater reliability was 0.996 (95% confidence interval [CI]: 0.992-0.998). The diagnostic cut-off value for the Mandarin version of the MDAS was 9, with a high sensitivity (93.1%) and specificity (96.9%). Factor analysis revealed a two-factor structure; these factors accounted for 58.37% and 14.42% of the variance. A high correlation was found between the MDAS and the CAM scores (r = -0.849, p < .001) as well as the MMSE (r = -0.875, p < .001). DISCUSSION The Mandarin MDAS exhibited good reliability and validity for assessing general hospital patients.

The detection of delirium in admitted oncology patients: a scoping review. Eur Geriatr Med 2022; 13:33-51. [PMID: 35032322 PMCID: PMC8860783 DOI: 10.1007/s41999-021-00586-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2021] [Accepted: 11/03/2021] [Indexed: 02/07/2023]
Abstract
Aim To understand the validation of delirium detection tools in medical oncology, as well as identify data on incidence, prevalence and reversibility in this setting. Findings Of twelve studies, only four used case ascertainment methods following published recommendations, six studies had a low risk of bias. Message In delirium tool validation studies in the oncology setting, choice of appropriate gold standard for case ascertainment is a critical factor. New tools and new validations are not recommended, rather the critical application of existing tools depending on appropriate validation and clinical practicality for the setting. Supplementary Information The online version contains supplementary material available at 10.1007/s41999-021-00586-1. Purpose Delirium leads to poor outcomes for patients and careers and has negative impacts on staff and service provision. Cancer rates in elderly populations are increasing and frequently, cancer diagnoses are a co-morbidity in the context of frailty. Data relating to the epidemiology of delirium in hospitalised cancer patients are limited. With the overarching purpose of improving delirium detection and reducing the morbidity and mortality of delirium in cancer patients, we reviewed the epidemiological data and approach to delirium detection in hospitalised, adult oncology patients. Methods MEDLINE, EMBASE, CINAHL, PsycINFO, and SCOPUS databases were searched from January 1996 to August 2017. Key concepts were delirium, cancer, inpatient oncology and delirium screening/detection. Results Of 896 unique studies identified; 91 met full-text review criteria. Of 12 eligible studies, four applied recommended case ascertainment methods to all patients, three used delirium screening tools alone or with case ascertainment tools sub-optimally applied, four used tools not recommended for delirium screening or case ascertainment, one used the Confusion Assessment Method with insufficient information to determine if it met case ascertainment status. Two studies presented delirium incidence rates: 7.8%, and 17% respectively. Prevalence rates ranged from 18–33% for general medical or oncology wards; 42–58% for Acute Palliative Care Units (APCU); and for older cancer patients: 22% and 57%. Three studies reported reversibility; 26% and 49% respectively (APCUs) and 30% (older patients with cancer). Six studies had a low risk of bias according to QUADAS-2 criteria; all studies in the APCU setting were rated at higher risk of bias. Tool selection, study flow and recruitment bias reduced study quality. Conclusion The knowledge base for improved interventions and clinical care for adults with cancer and delirium is limited by the low number of studies. A clear distinction between screening tools and diagnostic tools is required to provide an improved understanding of the rates of delirium and its reversibility in this population.

Abstract
BACKGROUND Delirium is a distressing neuropsychiatric disorder affecting patients in palliative care. Although many delirium screening tools exist, their utility, and validation within palliative care settings has not undergone systematic review. AIM To systematically review studies that validate delirium screening tools conducted in palliative care settings. DESIGN Systematic review with narrative synthesis (PROSPERO ID: CRD42019125481). A risk of bias assessment via Quality Assessment Tool for Diagnostic Accuracy Studies-2 was performed. DATA SOURCES Five electronic databases were systematically searched (January 1, 1982-May 3, 2020). Quantitative studies validating a screening tool in adult palliative care patient populations were included. Studies involving alcohol withdrawal, critical or perioperative care were excluded. RESULTS Dual-reviewer screening of 3749 unique titles and abstracts identified 95 studies for full-text review and of these, 17 studies of 14 screening tools were included (n = 3496 patients). Data analyses revealed substantial heterogeneity in patient demographics and variability in screening and diagnostic practices that limited generalizability between study populations and care settings. A risk of bias assessment revealed methodological and reporting deficits, with only 3/17 studies at low risk of bias. CONCLUSIONS The processes of selecting a delirium screening tool and determining optimal screening practices in palliative care are complex. One tool is unlikely to fit the needs of the entire palliative care population across all palliative care settings. Further research should be directed at evaluating and/or adapting screening tools and practices to fit the needs of specific palliative care settings and populations.

Abstract
CONTEXT Few studies have examined how clinicians assess decision-making capacity for research in the last weeks of life. OBJECTIVES We examined the decision-making capacity for participation in a research study and its association with clinician impression and delirium among patients with cancer with days to weeks of life expectancy. METHODS Patients admitted to our palliative and supportive care unit were approached for a prospective observational study. We assessed for their decision-making capacity based on clinical impression of physician and nurse, Memorial Delirium Assessment Scale (MDAS), and the MacArthur Competency Assessment Tool for Clinical Research (MacCAT-CR). RESULTS Among the 206 patients, 131 patients (64%) did not require MacCAT-CR assessment because they were overtly delirious or unresponsive; 37 (18%) patients were alert but did not complete the MacCAT-CR assessment for other reasons, and 38 patients (18%) completed the MacCAT-CR assessment. Among these 38 patients, five (13%) patients were incapable and had normal albeit significantly higher MDAS scores compared with those who were capable (1.8 vs. 4.2; P = 0.002). Compared against MacCAT-CR and MDAS, the overall agreement with capacity assessment with a clinician was 88% (95% CI 82-93) for physicians and 90% (95% CI 82-94) for nurses. The area under the receiver operating characteristics curve was 0.93 (95% CI 0.88-0.96) for physicians and 0.94 (95% CI 0.89-0.97) for nurses, suggesting high discrimination. CONCLUSION Most patients in the palliative and supportive care unit lacked decision-making capacity for participation in clinical research. Clinician impression had high accuracy. Few patients with normal MDAS were found to be incapable with MacCAT-CR assessment.

Abstract
OBJECTIVE Many patients with advanced serious illness or at the end of life experience delirium, a potentially reversible form of acute brain dysfunction, which may impair ability to participate in medical decision-making and to engage with their loved ones. Screening for delirium provides an opportunity to address modifiable causes. Unfortunately, delirium remains underrecognized. The main objective of this pilot was to validate the brief Confusion Assessment Method (bCAM), a two-minute delirium-screening tool, in a veteran palliative care sample. METHOD This was a pilot prospective, observational study that included hospitalized patients evaluated by the palliative care service at a single Veterans' Administration Medical Center. The bCAM was compared against the reference standard, the Diagnostic and Statistical Manual of Mental Disorders, fifth edition. Both assessments were blinded and conducted within 30 minutes of each other. RESULT We enrolled 36 patients who were a median of 67 years (interquartile range 63-73). The primary reasons for admission to the hospital were sepsis or severe infection (33%), severe cardiac disease (including heart failure, cardiogenic shock, and myocardial infarction) (17%), or gastrointestinal/liver disease (17%). The bCAM performed well against the Diagnostic and Statistical Manual of Mental Disorders, fifth edition, for detecting delirium, with a sensitivity (95% confidence interval) of 0.80 (0.4, 0.96) and specificity of 0.87 (0.67, 0.96). SIGNIFICANCE OF RESULTS Delirium was present in 27% of patients enrolled and never recognized by the palliative care service in routine clinical care. The bCAM provided good sensitivity and specificity in a pilot of palliative care patients, providing a method for nonpsychiatrically trained personnel to detect delirium.

Abstract
Background Delirium, a neuropsychiatric syndrome that occurs throughout medical illness trajectories, is frequently misdiagnosed. The Memorial Delirium Assessment Scale (MDAS) is a commonly used tool in palliative care (PC) settings. Our objective was to establish and validate the Memorial Delirium Assessment Scale‐Thai version (MDAS‐T) in PC patients. Materials and Methods The MDAS was translated into Thai. Content validity, inter‐rater reliability, and internal consistency were explored. The construct validity of the MDAS‐T was analyzed using exploratory factor analysis. Instrument testing of the MDAS‐T, the Thai version of the Confusion Assessment Method for the Intensive Care Unit (CAM‐ICU‐T), and the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition as the gold standard was performed. The receiver operating characteristic (ROC) curve was used to determine the optimal cutoff score. The duration of each assessment was recorded. Results The study enrolled 194 patients. The content validity index was 0.97. The intraclass correlation coefficient and Cronbach's α coefficient were 0.98 and 0.96, respectively. A principal component analysis indicated a homogeneous, one‐factor structure. The area under the ROC curve was 0.96 (95% confidence interval [CI], 0.93–0.99). The best combination of sensitivity and specificity (95% CI) of the MDAS‐T were 0.92 (0.85–0.96) and 0.90 (0.82–0.94), respectively, with a cutoff score of 9, whereas the CAM‐ICU‐T yielded 0.58 (0.48–0.67) and 0.98 (0.93–0.99), respectively. The median MDAS‐T assessment time was 5 minutes. Conclusion This study established and validated the MDAS‐T as a good and feasible tool for delirium screening and severity rating in PC settings. Implications for Practice Delirium is prevalent in palliative care (PC) settings and causes distress to patients and families, thereby making delirium screening necessary. This study found that the MDAS‐T is a highly objective and feasible test for delirium screening and severity monitoring in PC settings and can greatly improve the quality of care for this population. Delirium is often misdiagnosed. This article reports on the value of assessment tools for diagnosis of delirium, in particular the Memorial Delirium Assessment Scale, which was translated into Thai for purposes of this study.

Abstract
Aims: This study aims to evaluate the cognitive functions of patients with delirium using Hindi Mental Status Examination (HMSE), to study the correlation of cognitive functions assessed by HMSE with noncognitive symptoms as assessed using Delirium Rating Scale-Revised 1998 (DRS-R-98) and to study the association of cognitive functions assessed using HMSE and DRS-R98. Methods: A total of 76 consecutive patients fulfilling the diagnosis of delirium were evaluated on DRS-R-98, HMSE, and Short Informant Questionnaire on Cognitive Decline in the Elderly (retrospective IQCODE). Results: The mean DRS-R-98 score 33.9 (standard deviation [SD] - 7.2) and the mean DRS-R-98 severity score was 25.9 (SD - 7.2). The mean score on HMSE was 19.3 (7.98). There were significant correlations of all the domains of HMSE with DRS-R-98 total score, DRS-R-98 severity score, DRS-R-98 cognitive subscale score, DRS-R-98 noncognitive domain subscale score, and DRS severity score without attention score. When the association of each item of DRS-R-98 and HMSE was evaluated, except for the items of delusions, lability of affect and motor retardation, there were significant negative association between all the items of DRS-R-98 and HMSE, indicating that higher severity of cognitive symptoms as assessed on HMSE is associated with higher severity of all the cognitive symptoms and most of the noncognitive symptoms as assessed by DRS-R-98. Conclusion: The present study suggests that attention deficits in patients with delirium influence the severity of cognitive and noncognitive symptoms of delirium. Further, the present study suggests an increase in the severity of cognitive symptoms in other domains is also associated with an increase in the severity of noncognitive symptoms of delirium.

Symptom expression in advanced cancer patients admitted to hospice or home care with and without delirium. Intern Emerg Med 2019; 14:515-520.

Abstract
The aim of this study is to investigate the relationship between delirium and symptom expression in advanced cancer patients admitted to palliative care services. This is a secondary analysis of a consecutive sample of advanced cancer patients who were admitted to home care and hospices, and prospectively assessed for a period of 10 months. The Edmonton Symptom Assessment Scale (ESAS) and the MDAS (Memorial Delirium Assessment Scale) were measured at admission (T0) and after seven days of home care or hospice care (T7). Of the eight hundred and forty-eight patients screened in the period, 585 were not considered in the analysis for various reasons. The mean age was 72.1 years (SD 13.7), and 146 patients were males (55.5%). The mean Karnofsky status recorded at T0 is 34.1 (SD = 6.69). The mean duration palliative care assistance is 38.4 days (SD = 48, range 2-220). Of 263 patients who had a MDAS available at T0, 110 patients (41.8%) had a diagnosis of delirium. Of them, 167 patients had complete data regarding MDAS measurement, either at T0 and T7. A larger number of patients (n 167, 63.5%) had delirium after a week of palliative care. Patients with delirium are likely to be older, to have a lower Karnofsky level at T0, and to be home care patients. At T0, weakness, nausea, drowsiness, lack of appetite, and well-being are associated with delirium. At T7, weakness, poor appetite, and poor well-being are significantly associated with delirium. 27% of patients who had a normal cognitive status at T0 developed delirium at T7. In patients with delirium, an improvement in the cognitive status corresponds to a significant improvement in weakness, depression, and appetite. Conversely, the occurrence of delirium in patients who had a normal cognitive status at admission significantly increases the level depression, while the level of weakness and appetite decrease. Symptom expression is amplified in patients with delirium admitted to home care or hospices, while patients without delirium can be more responsive to palliative treatments with a significant decrease in intensity of ESAS items.

Abstract
INTRODUCTION Delirium is a significant medical complication for hospitalised patients. Up to one-third of delirium episodes are preventable in older inpatients through non-pharmacological strategies that support essential human needs, such as physical and cognitive activity, sleep, hydration, vision and hearing. We hypothesised that a multicomponent intervention similarly may decrease delirium incidence, and/or its duration and severity, in inpatients with advanced cancer. Prior to a phase III trial, we aimed to determine if a multicomponent non-pharmacological delirium prevention intervention is feasible and acceptable for this specific inpatient group. METHODS AND ANALYSIS The study is a phase II cluster randomised wait-listed controlled trial involving inpatients with advanced cancer at four Australian palliative care inpatient units. Intervention sites will introduce delirium screening, diagnostic assessment and a multicomponent delirium prevention intervention with six domains of care: preserving natural sleep; maintaining optimal vision and hearing; optimising hydration; promoting communication, orientation and cognition; optimising mobility; and promoting family partnership. Interdisciplinary teams will tailor intervention delivery to each site and to patient need. Control sites will first introduce only delirium screening and diagnosis, later implementing the intervention, modified according to initial results. The primary outcome is adherence to the intervention during the first seven days of admission, measured for 40 consecutively admitted eligible patients. Secondary outcomes relate to fidelity and feasibility, acceptability and sustainability of the study intervention, processes and measures in this patient population, using quantitative and qualitative measures. Delirium incidence and severity will be measured to inform power calculations for a future phase III trial. ETHICS AND DISSEMINATION Ethical approval was obtained for all four sites. Trial results, qualitative substudy findings and implementation of the intervention will be submitted for publication in peer-reviewed journals, and reported at conferences, to study sites and key peak bodies. TRIAL REGISTRATION NUMBER ACTRN12617001070325; Pre-results.

Abstract
AIM To assess the prevalence and intensity of constipation in advanced-cancer patients referred to palliative care, and to assess changes after 1 week of specialist palliative care. METHODS This was a prospective multi-center study in advanced patients for a period of 1 year. At admission (T0), age, gender, primary tumor, concomitant diseases, Karnofsky status, Palliative prognostic score (PaP), Edmonton Symptom Assessment scale (ESAS), Memorial Delirium Assessment Scale (MDAS), and bowel function index (BFI) were collected. In BFI, high values represent severe constipation. The use of medication was also recorded, as well as possible causes of constipation. The same parameters were recorded 1 week after admission for palliative care (T7). RESULTS A total of 246 patients were screened for constipation. The mean BFI at T0 was 42.4 (SD = 26.92). One hundred and sixty-three patients (66.3%) had a BFI >28. The mean BFI at T7 was 35.7 (SD = 28.8), with a significant decrease from T0 to T7 (p = .000). A significant decrease of BFI in patients with a BFI >28 was reported (p = .000). In patients with a BFI ≤28 there was a significant worsening of constipation (p = .000). In patients with a BFI >28 at T0 there was a significant increase in the use of laxatives at T7 in comparison with patients having a BFI ≤28 (p = .002). In patients with a BFI ≤28 at T0, who had a significant worsening of BFI (Δ > 12), the use of laxatives was significantly lower in comparison to patients who had a BFI >28 (p = .000). In the multivariate analysis, dehydration and the use of benzodiazepines were independently associated with higher BFI scores. CONCLUSION Constipation is present in approximately two-thirds of patients, and is principally associated with dehydration and the use of benzodiazepines. Patients with normal bowel function at initial assessment may see a worsening in their condition a week later due to lack of prevention or subsequent under-treatment.

Abstract
AIM This study aimed to explore the phenomenology, motor subtypes, and factor structure of symptom profile of delirium in patients admitted to the intensive care unit (ICU). METHODS Consecutive patients aged ≥16 years admitted in an ICU were screened daily for delirium using confusion assessment method-ICU. Patients diagnosed to have delirium as per Diagnostic and Statistical Manual fourth revision, text revision (DSM-IVTR) criteria were assessed with Delirium Rating Scale-Revised 98 (DRS-R 98) and Memorial Delirium Assessment Scale (MDAS). Motor subtypes of delirium were assessed with amended Delirium Motor Symptom Scale. RESULTS Sixty-six patients were evaluated for delirium, of which 45 (68%) patients developed delirium at point of their ICU stay. All patients had sleep-wake cycle disturbances, followed by motor symptoms (retardation - 80%; agitation - 73.3%). As per MDAS assessment, all the subjects had disturbances in the consciousness and sleep-wake cycle disturbances, and a substantial majority also had attention difficulties (93.3%) and motor symptoms (93.3%). Hypoactive subtype (47%) was the most common motoric subtype of delirium. Factor analysis revealed three-factor model for DRS-R 98, MDAS, and combining items of the two. CONCLUSION Phenomenology of delirium in ICU setting is similar to that of the non-ICU settings. The factor analysis consistently demonstrated a three factor solution, with a robust attention-arousal factor, and overlapping cognitive (core vs. non-core) motor factors.

Abstract
BACKGROUND Although Memorial Delirium Assessment Scale (MDAS) is a successful tool for delirium evaluation and monitoring, it is nevertheless important to determine whether cutoff scores vary according to the studied population. The main objective of this study was to evaluate the diagnostic sensitivity of the recently validated Spanish version of the MDAS. The secondary objective was to analyze possible diagnostic differences when used in a hospice or general hospital setting. METHODOLOGY A prospective study was conducted with advanced cancer patients in two settings (hospice and general hospital). A diagnosis of delirium was established according to clinical criteria and the Confusion Assessment Method. Sensitivity (S), specificity (Sp), positive predictive value, and negative predictive value were determined according to the receiver operating characteristics curve. The MDAS values for different centers were studied using nonparametric tests (Mann-Whitney). RESULTS A total of 67 patients were included, 28 of whom had been diagnosed with delirium (15/40 hospice and 13/27 general hospital). The mean MDAS scores were 13.6 and 5.5 for the delirium and nondelirium groups, respectively. A cutoff score of 7 gave the optimal screening diagnosis balance (S 92.6%, Sp 71.8%, positive predictive value 70.1%, and negative predictive value 93.3%). Diagnoses of anxiety and depression were not related with delirium (P ≤ 0.44). A diagnosis of dementia was related to delirium (P ≤ 0.052) but did not influence the diagnostic sensitivity of MDAS (P ≤ 0.26). No differences were found between hospice and general hospital settings as regards the diagnostic sensitivity of MDAS. CONCLUSION A screening cutoff of 7 appears to be optimal for MDAS Spanish version. No differences were found between advanced cancer patients cared for in a hospice or general hospital. However, more research is required to define the MDAS cutoff for patients with advanced cancer and dementia.

Abstract
AIM The aim of this study was to assess the prevalence of delirium in advanced cancer patients admitted to different palliative care services in Italy and possible related factors. The secondary outcome was to assess the changes of delirium after 1 week of palliative care. METHODS A consecutive sample of patients was screened for delirium in period of 1 year in seven palliative care services. General data, including primary tumor, age, gender, concomitant disease, palliative prognostic score (PaP), and Karnofsky status, were collected. Possible causes or factors associated with delirium were looked for. The Edmonton Symptom Assessment Scale was used to assess physical and psychological symptoms and the Memorial Delirium Assessment Scale (MDAS) to assess the cognitive status of patients, at admission (T0) and 1 week after palliative care (T7). RESULTS Of 848 patients screened, 263 patients were evaluated. Sixty-six patients had only the initial evaluation. The mean Karnofsky status was 34.1 (SD = 6.69); the mean PaP score at admission was 6.9 (SD = 3.97). The mean duration of palliative care assistance, equivalent to survival, was 38.4 days (SD = 48, range 2-220). The mean MDAS values at admission and after 1 week of palliative care were 6.9 (SD = 6.71) and 8.8 (SD = 8.26), respectively. One hundred ten patients (41.8%) and 167 patients (67.3%) had MDAS values ≥ 7 at admission and after 1 week of palliative care, respectively. Age, dehydration, cachexia, chemotherapy in the last three months, and intensity of drowsiness and dyspnea were independently associated with a MDAS > 7. A worsening of drowsiness, the use of opioids, and the use of corticosteroids were independently associated with changes of MDAS from T0 to T7. CONCLUSION Although the prevalence of delirium seems to be similar to that reported in other acute settings, delirium tended to worsen or poorly responded to a palliative care treatment. Some clinical factors were independently associated with delirium. This information is relevant for decision-making when delirium does not change despite a traditional intervention. Continuous assessment of delirium should be performed in these settings to detect deterioration of cognitive function. Further studies should elucidate whether an earlier approach to palliative care would decrease the prevalence of delirium at a late stage of disease.

Abstract
BACKGROUND Delirium is often unrecognized in cancer patients. The aim of this study was to investigate the prevalence of delirium assessed by the Memorial Delirium Assessment Scale (MDAS) and possible associated factors on admission to an acute palliative/supportive care unit (APSCU). The secondary outcome was to assess changes in MDAS and symptom burden at time of discharge. METHODS A consecutive sample of advanced cancer patients who were admitted to an APSCU was prospectively assessed for a period of 10 months. Patient demographics, including age, gender, primary diagnosis, Karnofsky status, stage of disease, and educational level were collected. The Edmonton Symptom Assessment Scale (ESAS) and the MDAS were measured at hospital admission and discharge. RESULTS A total of 314 patients were surveyed. Of 292 patients with MDAS available at T0, 74 (25.3%) and 24 (8.2%) had a MDAS of 7-12 and ≥13, respectively. At discharge, there was a significant decrease in the number of patients with a MDAS ≥7/30. Higher values of MDAS were associated with age (p = .028), a lower Karnofsky status (p < .0005), gender (male, p = .04), low level of education (p = .002), less awareness of disease (p < .0005), more indications for end-of-life care admission (p < .0005) or other symptoms (p = .026), hospital stay (p = .038) and death (p < .0005). Significant decreases in ESAS were observed in all patients independently of MDAS values (p < .0005). CONCLUSION Delirium is highly prevalent in patients admitted to APSCU, characterized by a low mortality due to early referral. Comprehensive assessment and treatment may allow a decrease in the level of cognitive disorders and symptom burden.

Abstract
OBJECTIVE To describe methodology used to diagnose delirium in research studies evaluating delirium detection tools. METHODS The authors used a survey to address reference rater methodology for delirium diagnosis, including rater characteristics, sources of patient information, and diagnostic process, completed via web or telephone interview according to respondent preference. Participants were authors of 39 studies included in three recent systematic reviews of delirium detection instruments in hospitalized patients. RESULTS Authors from 85% (N = 33) of the 39 eligible studies responded to the survey. The median number of raters per study was 2.5 (interquartile range: 2-3); 79% were physicians. The raters' median duration of clinical experience with delirium diagnosis was 7 years (interquartile range: 4-10), with 5% having no prior clinical experience. Inter-rater reliability was evaluated in 70% of studies. Cognitive tests and delirium detection tools were used in the delirium reference rating process in 61% (N = 21) and 45% (N = 15) of studies, respectively, with 33% (N = 11) using both and 27% (N = 9) using neither. When patients were too drowsy or declined to participate in delirium evaluation, 70% of studies (N = 23) used all available information for delirium diagnosis, whereas 15% excluded such patients. CONCLUSION Significant variability exists in reference standard methods for delirium diagnosis in published research. Increasing standardization by documenting inter-rater reliability, using standardized cognitive and delirium detection tools, incorporating diagnostic expert consensus panels, and using all available information in patients declining or unable to participate with formal testing may help advance delirium research by increasing consistency of case detection and improving generalizability of research results.

Front Aging Neurosci 2014; 6:297.

Abstract
Objective: Memorial Delirium Assessment Scale (MDAS) assesses severity of delirium. However, whether the MDAS can be used in a Chinese population is unknown. Moreover, the optimal postoperative MDAS cutoff point for describing postoperative delirium in Chinese remains largely to be determined. We therefore performed a pilot study to validate MDAS in the Chinese language and to determine the optimal postoperative MDAS cutoff point for delirium. Methods: Eighty-two patients (80 ± 6 years, 21.9% male), who had hip surgery under general anesthesia, were enrolled. The Confusion Assessment Method (CAM) and Mini-Mental State Examination (MMSE) were administered to the patients before surgery. The CAM and MDAS were performed on the patients on the first, second and fourth postoperative days. The reliability and validity of the MDAS were determined. A receiver operating characteristic (ROC) curve was used to determine the optimal Chinese version MDAS cutoff point for the identification of delirium. Results: The Chinese version of the MDAS had satisfactory internal consistency (α = 0.910). ROC analysis obtained an average optimal MDAS cutoff point of 7.5 in describing the CAM-defined postoperative delirium, with an area under the ROC of 0.990 (95% CI 0.977–1.000, P < 0.001). Conclusions: The Chinese version of the MDAS had good reliability and validity. The patients whose postoperative Chinese version MDAS cutoff point score was 7.5 would likely have postoperative delirium. These results have established a system for a larger scale study in the future.

Abstract
OBJECTIVE To analyse the evidence concerning the accuracy of the Mini-Mental State Examination (MMSE) as a diagnostic and screening test for the presence of delirium in adults. METHOD Two authors searched MEDLINE, PsychINFO and EMBASE from inception till March 2014. Articles were included that investigated the diagnostic validity of the MMSE to detect delirium against standardised criteria. A diagnostic validity meta-analysis was conducted. RESULTS Thirteen studies were included representing 2017 patients in medical settings of whom 29.4% had delirium. The meta-analysis revealed the MMSE had an overall sensitivity and specificity estimate of 84.1% and 73.0%, but this was 81.1% and 82.8% in a subgroup analysis involving robust high quality studies. Sensitivity was unchanged but specificity was 68.4% (95% CI = 50.9-83.5%) in studies using a predefined cutoff of <24 to signify a case. In high-risk samples where delirium was present in 25% of patients, then the Positive predictive value and Negative predictive value would be 50.9% (48.3-66.2%) and 93.2% (90.0-96.5%). CONCLUSION The MMSE cannot be recommended as a case-finding confirmatory test of delirium, but may be used as an initial screen to rule out high scorers who are unlikely to have delirium with approximately 93% accuracy.

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
CONTEXT The Memorial Delirium Assessment Scale (MDAS) is a reliable and validated instrument with which to assess delirium. However, MDAS responsiveness has only been investigated in an indirect way. Also, neurobehavioral and global cognitive factors seem to be the MDAS main factor loads. OBJECTIVES The primary objective of this study was to evaluate MDAS responsiveness and analyze individual factors on this scale. The secondary objective was to confirm concurrent validity and reliability of the Spanish version of the MDAS. METHODS The translation-back translation method was used to obtain the Spanish version of the MDAS. Delirium diagnosis was determined by the clinical Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria and with the Confusion Assessment Method. Responsiveness and factor loadings were determined with the Delirium Rating Scale-Revised-98, the Mini-Mental State Examination (MMSE), and the MDAS at baseline (0 hours) and at 72 hours. RESULTS Variation in the scores of the Delirium Rating Scale-Revised-98 shows a correlation of r = 0.93, with variation in MDAS scores at P < 0.001. Variation in MMSE scores shows a correlation of r = -0.84, with variation in MDAS scores at P = 0.015. Factor I, neurobehavioral (reduced awareness, reduced attention, perceptual disturbance, delusions, altered psychomotor activity, and sleep-wake cycle disturbance), correlated moderately with the MMSE at -0.56. Factor II, global cognitive (disorientation, short-term memory impairment, impaired digit span, and disorganized thinking), correlated strongly with the MMSE at -0.81. Factor II was significantly more reliable than Factor I, rho = 0.7, P = 0.01. CONCLUSION The high responsiveness confirms the value of the MDAS for ongoing delirium assessment. Two differentiated factor loadings point to a potential future need for MDAS subscales.

Abstract
Delirium's characteristic fluctuation in symptom severity complicates the assessment of test-retest reliability of scales using classical analyses, but application of modelling to longitudinal data offers a new approach. We evaluated test-retest reliability of the delirium rating scale (DRS) and delirium rating scale-revised-98 (DRS-R98), two widely used instruments with high validity and inter-rater reliability. Two existing longitudinal datasets for each scale included DSM-IV criteria for delirium diagnosis and repeated measurements using the DRS or DRS-R98. To estimate the reliability coefficients RT and RΛ for each scale we used a macros provided by Dr. Laenen at http://www.ibiostat.be/software/measurement.asp. For each dataset a linear mixed-effects model was fitted to estimate the variance-covariance parameters. A total of 531 cases with between 4 and 9 measurement points across studies including both delirious and non-delirious patients. Comorbid dementia in the datasets varied from 27% to 55%. Overall RT for the DRS were 0.71 and 0.50 and for DRS-R98 0.75 and 0.84. RΛ values for DRS were 0.99 and 0.98 and for DRS-R98 were 0.92 and 0.96. Individual RT measures for DRS-R98 and DRS across visits within studies showed more range than overall values. Our models found high overall reliability for both scales. Multiple factors impact a scale's reliability values including sample size, repeated measurements, patient population, etc in addition to rater variability.

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
AIM To study relationship between the cognitive and the non-cognitive symptoms of delirium. METHODS Eighty-four patients referred to psychiatry liaison services and met DSM-IVTR criteria of delirium were assessed using the Delirium Rating Scale Revised-1998 (DRSR-98) and Cognitive Test for Delirium (CTD). RESULTS The mean DRS-R-98 severity score was 17.19 and DRS-R-98 total score was 23.36. The mean total score on CTD was 11.75. The mean scores on CTD were highest for comprehension (3.47) and lowest for vigilance (1.71). Poor attention was associated with significantly higher motor retardation and higher DRS-R-98 severity scores minus the attention scores. There were no significant differences between those with and without poor attention. Higher attention deficits were associated with higher dysfunction on all other domains of cognition on CTD. There was significant correlation between cognitive functions as assessed on CTD and total DRS-R-98 score, DRS-R-98 severity score and DRS-R-98 severity score without the attention item score. However, few correlations emerged between CTD domains and CTD total scores with cognitive symptom total score of DRS-R-98 (items 9-13) and non-cognitive symptom total score of DRS-R-98 (items 1-8). CONCLUSIONS Our study suggests that in delirium, cognitive deficits are quite prevalent and correlate with overall severity of delirium. Attention deficit is a core symptom of delirium.

Abstract
Delirium is a frequently under-recognized complication in patients with advanced cancer. Uncontrolled delirium eventually leads to significant distress to patients and their families. However, delirium episodes can be reversed in half of these patients by eliminating precipitating factors and using appropriate interventions. The purpose of this narrative review is to discuss the most recent updates in the literature on the management of delirium in patients with advanced cancer. This article addresses the epidemiology, cause, pathophysiology, clinical characteristics, and assessment of delirium as well as various treatment options, including nonpharmacologic intervention and palliative sedation.

Abstract
BACKGROUND Delirium is common, has multiple causes and causes distress to numerous patients and their relatives. METHOD Selective review of the literature in PubMed and PsycINFO, with reference to selected national and international guidelines. RESULTS The hypoactive subtype of delirium is commoner than the hyperactive type, and often overlooked. Delirium in an elderly individual is associated with an additional burden, a possible loss of potential for rehabilitation, and a marked increase in mortality. The diagnosis of delirium is primarily clinical. All professionals involved in patient care must be able to recognize the features of delirium. Dementia, dehydration and polypharmacy are particularly strongly associated, in the elderly. A careful history and examination with appropriate investigation allows underlying causes to be detected and treated. Rehabilitation strategies should be initiated without delay. Neuroleptics and benzodiazepines have an established role in the pharmacological treatment even of the hyperactive subtype. Non-pharmacological treatments include the creation of a calm and patient centred environment, and the involvement of relatives. CONCLUSION In many cases, delirium can be diagnosed and treated in good time. Prevention is preferable to treatment.

Abstract
BACKGROUND Very few studies from India have studied the phenomenology of delirium. The aim of the present study was to study the phenomenology as measured using the Delirium Rating Scale-Revised-98 (DRS-R98), the associated etiologies and the outcome of delirium among the elderly participants seen by the consultation-liaison psychiatric service in India. In addition, an attempt was made to study the factor structure of symptoms using principal components analysis. METHODS The case notes of 109 elderly patients referred to psychiatry liaison services were reviewed. RESULTS The mean age of the sample was 73.35 years (SD: 7.44; range 65-95 years) and two-thirds of the sample had hospital emergent delirium. The mean DRS-R98 severity score was 18.77 and the DRS-R98 total score was 24.81. In 15 patients the DRS-R98 scores were in the subsyndromal range. Among the various symptoms present, most patients had sleep-wake cycle disturbance, disturbance in orientation, attention and short-term memory impairments, fluctuation of symptoms, temporal onset of symptoms and a physical disorder. Principal components analysis identified three factors which explained 43.5% of variance of symptomatology and it yielded a three-factor structure. Endocrine/metabolic disturbances were the commonest associated etiological category with delirium. The mean hospital stay after being referred to psychiatry referral services was 8.89 days, after which delirium improved in 58.7% of cases. The mortality rate during the inpatient stay was 16.5%. CONCLUSIONS Results suggest that the symptoms of delirium as assessed by DRS-R98 separate out into a three-factor structure. Delirium is commonly associated with metabolic endocrine disturbances and about one-sixth of the patients die during the short inpatient stay.

Abstract
OBJECTIVE Factor analytic studies of delirium symptoms among patients referred through consultation-liaison psychiatric services are rare. We examined the factor structure of delirium symptoms in referred patients and determined whether combining items from several delirium rating scales influenced the factor structure of delirium symptoms. METHOD Eighty-six patients with delirium (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision) referred though the consultation-liaison services were assessed with structured rating scales. Nineteen symptom items extracted from the Delirium Rating Scale-Revised-98 (DRS-R-98), the Memorial Delirium Assessment Scale and the Confusional State Evaluation Scale were subjected to an exploratory (principal component) factor analysis. A second such analysis was conducted on 15 items of the DRS-R-98 for comparison. RESULTS Compared with prior studies, patients were younger and the majority had hyperactive delirium. Principal components analysis identified two factors: (1) a "cognitive" factor comprising of disturbances in language, thought processes, orientation, attention, short- and long-term memory, visuospatial ability, consciousness (awareness) and perseveration accounted for 28.9% of the variance and (2) a "behavioral" factor consisting of sleep-wake cycle disturbances, delusions, perceptual disturbances, motor agitation, affect-lability, distractibility, irritability and temporal onset accounted for 18.9% of the variance. An identical factor structure was obtained with the DRS-R-98 items. CONCLUSIONS Similar to previous factor analytic studies, the present study supported the existence of two principal dimensions of delirium, cognitive and behavioral. Additionally, it extended the results of earlier investigations to a wider group of patients with delirium, suggesting that these dimensions might provide important clues to the neurobiology of delirium.

Abstract
OBJECTIVE Existing factor analytic studies of symptoms of delirium are mostly based on small numbers of patients from specialized settings. This study thus sought to examine the factor structure of symptoms of delirium in a reasonably large sample of untreated patients referred to liaison psychiatric services of a multi-specialty hospital in north India, employing the more commonly used Delirium Rating Scale-Revised Version-1998 (DRS-R-98). METHOD Patients (n=151) who met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria for delirium were assessed with the DRS-R-98 prior to starting treatment with psychotropics. A principal component analysis was carried out to determine the factor structure of the symptoms based on these ratings. RESULTS Unlike previous efforts, patients of this study were relatively younger (mean age 47 years), with mainly hyperactive delirium, and did not have comorbid dementia. Three factors which together explained 47.32 % of variance of symptoms were identified. A "global cognitive" factor including disturbances of orientation, attention, short- and long-term memory, and visuospatial ability accounted for 18.33% of the variance. A "sleep and motor symptoms" factor consisting of sleep-wake cycle disturbances; delusions; and perceptual disturbances including hallucinations, motor-agitation, inverse of motor-retardation, and affect-lability accounted for 16% of the variance. A "thought and language" factor comprising abnormalities in language and thought process, temporal onset, and fluctuation of symptoms explained 13% of the variance. CONCLUSIONS Thus, the current factor analysis not only confirmed the presence of three principal symptom dimensions of delirium (found in several previous studies) but also extended these findings to a broader group of patients usually referred to liaison psychiatric services.

Abstract
PURPOSE To identify prevalence and associated factors of cognitive dysfunction in opioid-treated patients with cancer. PATIENTS AND METHODS EPOS (European Pharmacogenetic Opioid Study) is a prospective cross-sectional multicenter study in which adult patients with cancer who received treatment with opioids for moderate or severe pain for at least 3 days were included. Cognitive function was assessed using the Mini-Mental State Examination (MMSE). MMSE scores were categorized into definite cognitive dysfunction (scores < 24), possible cognitive dysfunction (scores 24-26), and no cognitive dysfunction (scores > 26). Factors potentially associated with cognitive dysfunction were assessed. Associations between MMSE and explanatory variables were analyzed by ordinal logistic regression models. RESULTS We included 1,915 patients with cancer from 17 centers. MMSE scores less than 27 were observed in 32.9% of patients. Patients with lung cancer had higher odds (adjusted odds ratio, 1.46; 95% CI, 1.09 to 1.95) for having lower MMSE scores compared with patients with other cancer diagnoses. Patients receiving daily opioid doses of 400 mg or more (oral morphine equivalents) had 1.75 (95% CI, 1.25 to 2.46) times higher odds of having lower MMSE scores compared with those receiving daily doses less than 80 mg. Other risk factors for cognitive dysfunction were older age, low Karnofsky performance status (KPS), time since diagnosis (< 15 months), and absence of breakthrough pain (BTP). CONCLUSION One third of opioid-treated patients with cancer had possible or definite cognitive dysfunction. Lung cancer, daily opioid doses of 400 mg or more (oral morphine equivalents), older age, low KPS, shorter time since cancer diagnosis, and absence of BTP were predictors for cognitive dysfunction.

Abstract
PURPOSE To determine pre- and post-transplantation risk factors for delirium onset and severity during the acute phase of myeloablative hematopoietic stem-cell transplantation (HSCT). PATIENTS AND METHODS Ninety adult patients with malignancies admitted to the Fred Hutchinson Cancer Research Center for their first HSCT were assessed prospectively from 1 week before transplantation to 30 days after transplantation. Delirium was assessed three times per week using the Delirium Rating Scale and the Memorial Delirium Assessment Scale. Potential risk factors were assessed by patient self-report, charts, and computerized records. Multivariable analysis of time to onset of a delirium episode was undertaken using Cox proportional hazards regression with time-varying covariates. Analysis for delirium severity was carried out using a linear mixed effects model. Validation and sensitivity analyses were performed on the final models. RESULTS Forty-five patients (50%) experienced a delirium episode. Pretransplantation risk factors for onset and higher severity of delirium were higher mean alkaline phosphatase and blood urea nitrogen (BUN) levels. Poorer pretransplantation executive functioning was also associated with higher delirium severity. Higher doses of opioid medications were the only post-transplantation risk factor for delirium onset (hazard ratio, 1.05; 95% CI, 1.02 to 1.08). Higher opioid doses, current and prior pain, and higher BUN levels were post-transplantation risk factors for greater delirium severity (all P < .01). CONCLUSION Pre- and post-transplantation factors can assist in identifying patients who are at risk for delirium during myeloablative HSCT and may enable clinical interventions to prevent delirium onset or decrease delirium symptoms.

Abstract
BACKGROUND Delirium is a common complication of myeloablative hematopoietic stem-cell transplantation (HSCT), yet no studies have explored the later effects of an episode of delirium in this setting on patients' decision-making capacity after the acute symptoms of delirium have resolved. OBJECTIVE The authors assessed the impact of delirium during the acute phase of myeloablative HSCT on later decision-making capacity. METHOD Decision-making capacity was assessed with the MacArthur Competence Assessment Tool in 19 patients before they received their first HSCT and at 30 and 80 days post-transplantation. Delirium was assessed 3 times per week with the Delirium Rating Scale and the Memorial Delirium Assessment Scale from 7 days pre-transplantation through 30 days post-transplantation. RESULTS Although there was little variance in the pre-treatment scores, with most patients showing very high or perfect scores on decision-making abilities, a multivariate regression model showed that delirium was predictive of a lower reasoning score at Day 30 post-transplantation. CONCLUSION Patients who experienced a delirium episode during the acute phase of HSCT were not likely to develop clinically meaningful impairments in decision-making capacity post-transplantation, although they evidenced minor impairment in their reasoning ability.

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
OBJECTIVES This review focuses on phenomenological studies of delirium, including subsyndromal and prodromal concepts, and their relevance to other elements of clinical profile. METHODS A Medline search using the keywords delirium, phenomenology, and symptoms for new data articles published in English between 1998 and 2008 was utilized. The search was supplemented by additional material not identified by Medline but known to the authors. RESULTS Understanding of prodromal and subsyndromal concepts is still in its infancy. The characteristic profile can differentiate delirium from other neuropsychiatric disorders. Clinical (motoric) subtyping holds potential but more consistent methods are needed. Studies are almost entirely cross-sectional in design and generally lack comprehensive symptom assessment. Multiple assessment tools are available but are oriented towards hyperactive features and few have demonstrated ability to distinguish delirium from dementia. There is insufficient evidence linking specific phenomenology with etiology, pathophysiology, management, course, and outcome. CONCLUSIONS Despite the major advancements of the past decade in many aspects of delirium research, further phenomenological work is crucial to targeting studies of causation, pathophysiology, treatment, and prognosis. We identified eight key areas for future studies.

Abstract
OBJECTIVE To assess the validity and the reliability of the Portuguese version of the Delirium Rating Scale-Revised-98 (DRS-R-98). METHODS The scale was translated into Portuguese and back-translated into English. After assessing its face validity, five diagnostic groups (n=64; delirium, depression, dementia, schizophrenia and others) were evaluated by two independent researchers blinded to the diagnosis. Diagnosis and severity of delirium as measured by the DRS-R-98 were compared to clinical diagnosis, Mini-Mental State Exam, Confusion Assessment Method, and Clinical Global Impressions scale (CGI). RESULTS Mean and median DRS-R-98 total scores significantly distinguished delirium from the other groups (p<0.001). Inter-rater reliability (ICC between 0.9 and 1) and internal consistency (alpha=0.91) were very high. DRS-R-98 severity scores correlated highly with the CGI. Mean DRS-R-98 severity scores during delirium differed significantly (p<0.01) from the post-treatment values. The area under the curve established by ROC analysis was 0.99 and using the cut-off value of 20 the scale showed sensitivity and specificity of 92.6% and 94.6%, respectively. CONCLUSION The Portuguese version of the DRS-R-98 is a valid and reliable measure of delirium that distinguishes delirium from other disorders and is sensitive to change in delirium severity, which may be of great value for longitudinal studies.

Abstract
OBJECTIVES To examine the psychometric properties, adaptations, translations, and applications of the Confusion Assessment Method (CAM), a widely used instrument and diagnostic algorithm for identification of delirium. DESIGN Systematic literature review. SETTING Not applicable. MEASUREMENTS Electronic searches of PubMED, EMBASE, PsychINFO, CINAHL, Ageline, and Google Scholar, augmented by reviews of reference listings, were conducted to identify original English-language articles using the CAM from January 1, 1991, to December 31, 2006. Two reviewers independently abstracted key information from each article. PARTICIPANTS Not applicable. RESULTS Of 239 original articles, 10 (4%) were categorized as validation studies, 16 (7%) as adaptations, 12 (5%) as translations, and 222 (93%) as applications. Validation studies evaluated performance of the CAM against a reference standard. Results were combined across seven high-quality studies (N=1,071), demonstrating an overall sensitivity of 94% (95% confidence interval (CI)=91-97%) and specificity of 89% (95% CI=85-94%). The CAM has been adapted for use in the intensive care unit, emergency, and institutional settings and for scoring severity and subsyndromal delirium. The CAM has been translated into 10 languages where published articles are available. In application studies, CAM-rated delirium is most commonly used as a risk factor or outcome but also as an intervention or reference standard. CONCLUSION The CAM has helped to improve identification of delirium in clinical and research settings. To optimize performance, the CAM should be scored based on observations made during formal cognitive testing, and training is recommended. Future action is needed to optimize use of the CAM and to improve the recognition and management of delirium.

Abstract
PURPOSE To determine the impact of delirium during the acute phase of myeloablative hematopoietic stem-cell transplantation (HSCT) on health-related quality of life (HRQOL), distress, and neurocognitive functioning 30 and 80 days after transplantation. PATIENTS AND METHODS Ninety patients completed a battery assessing HRQOL, distress, and neuropsychological functioning before receiving their first HSCT. Delirium was assessed three times per week using the Delirium Rating Scale and the Memorial Delirium Assessment Scale from 7 days before transplantation through 30 days after transplantation. At 30 days after transplantation, distress and neurocognitive functioning were assessed. At 80 days after transplantation, HRQOL, distress, and neuropsychological functioning were re-evaluated. RESULTS After adjusting for confounding factors, patients who experienced a delirium episode, versus patients who did not, reported significantly worse depression, anxiety, and fatigue symptoms at 30 days (linear regression beta(s) = 0.2, 0.3, and 0.5, respectively; P < .04). At 80 days, patients with a delirium episode had significantly worse executive functioning (beta = -1.1; P < .02), attention and processing speed (beta(s) = -4.7 and -5.4, respectively; P < .03), mental health on the Medical Outcomes Study Health Survey, 12-item short form (beta = -6.5; P < .02), and anxiety, fatigue, and cancer and treatment distress symptoms (beta(s) = 0.4, 0.6, and 0.3, respectively; P < .03). CONCLUSION Patients with a malignancy who experience delirium during myeloablative HSCT showed impaired neurocognitive abilities and persistent distress 80 days after transplantation. Effective prevention or treatment of delirium during HSCT may improve both cognitive and psychological outcomes.

Abstract
BACKGROUND Delirium is among the most common neuropsychiatric complications of advanced cancer. The Memorial Delirium Assessment Scale (MDAS) is a widely used and validated screening tool for delirium in cancer patients. OBJECTIVE The purpose of this study was to assess the use of the MDAS by different palliative care health professionals after receiving formal training and a guiding manual for administration and scoring. MATERIALS AND METHODS Thirty-one palliative care health professionals received a training session on the MDAS, including description of the tool, validation, and scoring. Participants also received copies of a proposed standardized manual for completion of the MDAS. Two of the investigators presented three simulated cases to the participants, who independently completed a scoring sheet for each case. The data were then analyzed according to the cases and the profession of the operators. RESULTS Thirty-one scoring sheets were analyzed (11 physicians, 12 nurses, and 8 others). A correct diagnosis was achieved by 30 (96.8%) of the 31 participants in case 1 (nondelirious, true score = 5, median = 5, range = 2-15), 28 of 31 (90.3%) in case 2 (severe mixed delirium, true score = 20, median = 18, range = 10-26), and 31 of 31 in case 3 (mild hypoactive delirium, true score = 14, median = 19, range = 13-25). Overall percentage of error was 31% for items 2, 3, and 4 (cognitive) and 45% for all other items (observational) (p < 0.001). The percentage of error did not differ between physicians and nurses and other palliative care professionals (p > 0.99). CONCLUSIONS Our preliminary results suggest that adequate training and a guiding manual can enhance the application of MDAS by palliative care health professionals in the teaching settings. Clinical studies to assess the utility of the MDAS as a screening tool are justified to further confirm these findings.

Abstract
This study was based on the data collected on a consecutive sample of 106 cancer patients referred for mental status evaluation. All patients were evaluated by use of the Confusion Assessment Method (CAM) algorithm, the Delirium Rating Scale (DRS), the Memorial Delirium Assessment Scale (MDAS), and a question about the subjective perception of delirium. After comparing the diagnostic criteria of delirium on the DSM-III-R and DSM-IV, authors evaluated the ability of all DRS and MDAS items to discriminate delirium versus non-delirium patients, testing the difference in the distribution of the individual MDAS and DRS item scores. Authors also assessed the relationship between delirium diagnosis and the subjective perception of delirium. The MDAS showed a greater number of discriminating items. The items that proved to be less discriminating were "Hallucinations" and "Lability of Mood" on the DRS. Subjective perception only partially discriminated delirium from non-delirium patients. The way in which the DRS and MDAS reflected the DSM criteria are therefore partially different.

Abstract
Because no rigorously validated, simple yet accurate continuous delirium assessment instrument exists, we developed the Nursing Delirium Screening Scale (Nu-DESC). The Nu-DESC is an observational five-item scale that can be completed quickly. To test the validity of the Nu-DESC, 146 consecutive hospitalized patients from a prospective cohort study were continuously assessed for delirium symptoms by bedside nurses using the Nu-DESC. Psychometric properties of Nu-DESC screening were established using 59 blinded Confusion Assessment Method (CAM) ratings made by research nurses and psychiatrists. DSM-IV criteria and the Memorial Delirium Assessment Scale (MDAS) were rated along with CAM assessments. Analysis of these data showed that the Nu-DESC is psychometrically valid and has a sensitivity and specificity of 85.7% and 86.8%, respectively. These values are comparable to those of the MDAS, a longer instrument. Nu-DESC and DSM-IV sensitivities were similar. The Nu-DESC appears to be well-suited for widespread clinical use in busy oncology inpatient settings and shows promise as a research instrument.

Abstract
BACKGROUND Delirium is common in patients undergoing hematopoietic stem cell transplantation (HSCT) and is associated with considerable morbidity and excess mortality in diverse patient samples. Although delirium can be treated successfully, it is largely undiagnosed. Understanding the clinical presentation of delirium may help improve the recognition of delirium in these patients. In the current study, the authors investigated the clinical presentation of delirium in HSCT patients, including the time course of these symptoms and comorbid affective distress, fatigue, and pain. METHODS Ninety patients ages 22-62 years were recruited prior to undergoing their first allogeneic or autologous HSCT. Delirium, distress, and pain symptom assessments were conducted prospectively 3 times per week from pretransplantation through Day 30 posttransplantation. RESULTS Delirium episodes occurred in 50% of patients and lasted approximately 10 days, with peak severity at the end of the second week posttransplantation. Factor analysis revealed three groups of delirium symptoms representing psychosis-behavior, cognition, and mood-consciousness. Delirium episodes were characterized by rapid onset of psychomotor and sleep-wake cycle disturbance that persisted and cognitive symptoms that continued to worsen throughout much of the episode. Rises in psychosis-behavior and cognitive symptoms predated the start of delirium episodes by approximately 4 days. Affective distress and fatigue were common and appeared to be associated most with psychosis-behavioral delirium symptoms. CONCLUSIONS The results describe in detail the clinical presentation of delirium in patients undergoing HSCT. Affective distress and fatigue commonly were associated with delirium. These findings may aid clinicians in improving the recognition and treatment of delirium in this population and avoiding further morbidity and potential mortality.
