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.

Abstract
INTRODUCTION Delirium is a neurocognitive disorder common in older adults in acute care settings. Those who develop delirium are at an increased risk of dementia, cognitive decline and death. Electroencephalography (EEG) during delirium in older adults is characterised by slowing and reduced functional connectivity, but markers of vulnerability are poorly described. We aim to identify EEG spectral power and event-related potential (ERP) markers of incident delirium in older adults to understand neural mechanisms of delirium vulnerability. Characterising delirium vulnerability will provide substantial theoretical advances and outcomes have the potential to be translated into delirium risk assessment tools. METHODS AND ANALYSIS We will record EEG in 90 participants over 65 years of age prior to elective coronary artery bypass grafting (CABG) or transcatheter aortic valve implantation (TAVI). We will record 4-minutes of resting state (eyes open and eyes closed) and a 5-minute frequency auditory oddball paradigm. Outcome measures will include frequency band power, 1/f offset and slope, and ERP amplitude measures. Participants will undergo cognitive and EEG testing before their elective procedures and daily postoperative delirium assessments. Group allocation will be done retrospectively by linking preoperative EEG data according to postoperative delirium status (presence, severity, duration and subtype). ETHICS AND DISSEMINATION This study is approved by the Human Research Ethics Committee of the Royal Adelaide Hospital, Central Adelaide Local Health Network and the University of South Australia Human Ethics Committee. Findings will be disseminated through peer-reviewed journal articles and presentations at national and international conferences. TRIAL REGISTRATION NUMBER ACTRN12618001114235 and ACTRN12618000799257.

Abstract
Delirium is the most common psychiatric diagnoses encountered in patients with various medical-surgical illnesses, in all the treatment set-ups, with relatively higher incidence and prevalence in the intensive care units. As delirium is encountered in multiple specialties, it is important to understand the research on this diagnosis. This study aims to assess the research output involving patients of delirium from India. A comprehensive search was undertaken using Medline (PubMed) and other databases. Search words included were “delirium,” “delirious,” “delirium tremens” AND “India.” No filters were used. Internet and hand searches yielded 305 articles. Out of these articles, 151 had the terms “delirium,” “delirious,” “delirium tremens” in the title and these were included for the review. Additionally, 14 articles were included for the review, although these did not have these terms in the title, but delirium was one of the major outcome parameters in these studies. Majority of the papers were original articles (
n
= 81), and these were followed by, case reports (
n
= 58), review articles (
n
= 10), letter to the editor (not as case reports but as a communication;
n
= 13), editorials (
n
= 2) and one clinical practice guideline. Most of the original papers have either focused on epidemiology (incidence, prevalence, outcome, etc.), symptom profile, with occasional studies focusing on effectiveness of various pharmacological interventions. There is a dearth of research in the field of delirium from India. There is a lack of studies on biomarkers, evaluation of nonpharmacological interventions, and evaluation of prevention strategies. It is the need of the hour to carry out more studies to further our understanding of delirium in the Indian context.

Validity and Reliability of the Memorial Delirium Assessment Scale-Thai Version (MDAS-T) for Assessment of Delirium in Palliative Care Patients. Oncologist 2019; 25:e335-e340. [PMID: 32043769 PMCID: PMC7011635 DOI: 10.1634/theoncologist.2019-0399] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2019] [Accepted: 10/14/2019] [Indexed: 12/03/2022] Open
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
CONTEXT Current guidelines recommend early referral to palliative care for patients with advanced cancer; however, no studies have examined the optimal timing of referral from the patients' perspective. OBJECTIVES To examine patients' perceptions of timeliness of referral and its association with survival among patients with advanced cancer referred to an outpatient supportive care (SC) clinic. METHODS This cross-sectional prospective study in an SC clinic at a comprehensive cancer center included patients aged 18 years or older with locally advanced, recurrent, or metastatic cancer. Patients were asked to complete an anonymous survey regarding the timeliness and perceived usefulness of SC referral within four weeks of their first SC consultation. RESULTS Of 253 eligible patients, 209 (83%) enrolled in the study and 200 completed the survey. Median survival was 10.3 months. Most patients (72%) perceived that referral occurred "just in time," whereas 21% felt it was "late," and 7% felt "early." A majority (83%) found the referral useful, and 88% would recommend it to other patients with cancer. The perception of being referred early was associated with lower reported levels of pain (P = 0.043), fatigue (P = 0.004), drowsiness (P = 0.005), appetite loss (P = 0.041), poor well-being (P = 0.041), and lower physical (P = 0.001) and overall symptom distress (P = 0.001). No other associations were found between perceived timeliness and usefulness and patients' baseline characteristics. CONCLUSION Most patients with a median survival of 10 months perceived that SC referral was timely and useful. Patient care needs rather than the timing of advanced cancer diagnosis drove this perception of referral timing. Lower symptom burden was associated with the perception of being referred to early.

Abstract
BACKGROUND Delirium is a frequent yet underdiagnosed neuropsychiatric condition encountered in intensive care units (ICUs). Being both a preventable and potentially reversible process associated with significant morbidity and mortality, understanding risk factors that predispose and precipitate delirium in any given patient are critical in ICUs. AIMS AND OBJECTIVES The aim of this study is to evaluate the incidence, motor subtypes, risk factors, and clinical outcome of delirium in the medical ICU. MATERIALS AND METHODS We used a prospective study design on a cohort of consecutive medical ICU admissions of a tertiary care teaching hospital. The Confusion Assessment Method-ICU and Richmond Agitation Sedation Scale were used to diagnose and motor subtype delirium, respectively, along with a checklist to assess risk factors. RESULTS Of the 280 ICU admissions, 88 (31.4%) developed delirium. Hypoactive delirium was the most common motor subtype (55.7%). The detection rate of delirium was 12.5% (lowest for hypoactive delirium at 2.04%). Age, gender, and years of education did not significantly predict delirium (all P > 0.05). Tobacco use, chronic liver disease, and past episodes of delirium significantly predisposed, while mechanical ventilation, hypoxia, fever, raised levels of bilirubin and creatinine, and benzodiazepine administration significantly precipitated ICU delirium. Delirium was significantly associated with longer ICU stay (t = 4.23, P = 0.000) and 1-month postdischarge mortality (χ 2 = 6.867, P = 0.009). CONCLUSION Detection of delirium is challenging, especially in ICU patients on mechanical ventilation and hypoactive delirium. Screening and monitoring for predisposing and precipitating risk factors can greatly improve the odds of detection and intervention as ICU delirium is associated with significant morbidity and mortality.

Abstract
OBJECTIVE To determine the timing of palliative care (PC) access, symptoms, and end-of-life (EOL) quality care outcomes of patients with advanced nonsmall cell lung cancer (NSCLC) referred to outpatients embedded palliative care consults (EPC) compared with those of outpatients palliative care consults (OPC). BACKGROUND There are no studies comparing the outcomes of outpatients EPC consults with those of stand-alone OPC consults among patients with NSCLC. DESIGN The design consists of a random sample of OPC consults (January 2009 to July 2012) and EPC consults (August 2012 to June 2013) at MD Anderson Cancer Center. After the initial consult, all EPC follow-ups occurred at the OPC clinic. MEASUREMENTS Patients' characteristics, symptoms (assessed by Edmonton Symptom Assessment Scale), time from referral to first consult, overall survival from consult to death, and EOL quality care outcomes (ICU admissions, emergency center visits, hospitalizations within last 30 days, cancer treatments within last 14 days, hospice referrals, advanced care planning [ACP] discussions, and completion of advanced directives) were reviewed. RESULTS A total of 340 consults were included (EPC consults = 147). Baseline Eastern Cooperative Oncology Group status (2.2 vs. 1.9, p < 0.001) and median pain (6 vs. 5, p = 0.038) were higher among EPC consults. In EPC consults, time from referral to first consult was shorter (median: 0 day vs. 7 days, p < 0.001), and ACP discussions occurred more frequently (90% vs. 77%, p = 0.026), and earlier (median: 2 month vs. 1 month before death, p = 0.018). No other significant differences in symptoms, EOL outcomes, or survival were observed. CONCLUSIONS EPC consults plus OPC follow-ups accessed PC earlier, and had more frequent and earlier ACP discussions as compared with OPC consults. Embedded palliative cancer care might not be the ideal model for an initial PC consultation. Further research is necessary.

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 Medications are frequently reported as both predisposing factors and inducers of delirium. This review evaluated the available evidence and determined the magnitude of risk of postoperative delirium associated with preoperative medication use. METHODS A systematic search in Medline and EMBASE was conducted using MeSH terms and keywords for postoperative delirium and medication. Studies which included patients 18 years and older who underwent major surgery were included. The methodological quality of included studies was assessed independently by two authors using the Newcastle-Ottawa quality assessment scale for cohort studies. RESULTS Twenty-nine studies; 25 prospective cohort, three retrospective cohort and one post hoc analysis of RCT data were included. Only four specifically aimed to assess medicines as an independent predictor of delirium, all other studies included medicines among a number of potential predictors of delirium. Of the studies specifically testing the association with a medication class, preoperative use of beta-blockers (OR = 2.06[1.18-3.60]) in vascular surgery and benzodiazepines RR 2.10 (1.23-3.59) prior to orthopedic surgery were significant. However, evidence is from single studies only. Where medicines were included as one possible factor among many, hypnotics had a similar risk estimate to the benzodiazepine study, with one significant and one non-significant result. Nifedipine use prior to cardiac surgery was found to be significantly associated with delirium. The non-specific grouping of psychoactive medication use preoperatively was generally higher with an associated two-to-seven-fold higher risk of postoperative delirium, while only two studies included narcotics without other agents, with one significant and one non-significant result. CONCLUSIONS There was a limited number of high quality studies in the literature quantifying the direct association between preoperative medication use and postsurgical delirium. More studies are required to evaluate the association of specific preoperative medications on the risk of postoperative delirium so that comprehensive guidelines for medicine use prior to surgery can be developed to aid delirium prevention. TRIAL REGISTRATION This systematic review has been registered on PROSPERO International prospective register of systematic reviews (Registration number: CRD42016051245 ).

Abstract
AIM To study the phenomenology and motor sub-types of delirium in patients admitted in a Coronary Care Unit (CCU). METHODS Three hundred and nine consecutive patients were screened for delirium, and those found positive for the same were evaluated by a psychiatrist on DSM-IVTR criteria to confirm the diagnosis. Those with a diagnosis of delirium were evaluated on the DRS-R-98 to study the phenomenology and on the amended Delirium Motor Symptom Scale (DMSS) to study the motor sub-types. RESULTS Eighty-one patients were found to have delirium. Commonly seen symptoms of delirium included: disturbances in sleep-wake cycle, lability of affect, thought abnormality, disturbance in attention, disorientation, short-term memory, and long-term memory. Very few patients had delusions. More than half of the participants were categorized as having hyperactive (n = 46; 56.8%) followed by hypoactive sub-type (n = 21; 26%) and mixed sub-type (n = 9; 11.1%) of delirium. There were minor differences in the frequency and severity of symptoms of delirium between incidence and prevalence cases of delirium and those with different motoric sub-types. CONCLUSION Delirium in CCU set-up is characterized by the symptoms of disturbances in sleep-wake cycle, lability of affect, thought abnormality, disturbance in attention, disorientation, short-term memory, and long-term memory. Hyperactive delirium is more common than hypoactive delirium.

Abstract
OBJECTIVES To derive and validate a method for scoring delirium severity using a recently validated, brief, structured diagnostic interview for Confusion Assessment Method (CAM)-defined delirium (3D-CAM) and to demonstrate its agreement with the CAM Severity short form (CAM-S SF) as the reference standard. DESIGN Derivation and validation analysis in a prospective cohort study. SETTING Two academic medical centers. PARTICIPANTS Individuals aged 70 and older enrolled in the Successful Aging after Elective Surgery Study undergoing major elective noncardiac surgery (N = 566). MEASUREMENTS The sample was randomly divided into a derivation dataset (n = 377) and an independent validation dataset (n = 189). These datasets were used to develop a severity scoring method using the 3D-CAM based on the four-item CAM-S SF (3D-CAM-S) and evaluate agreement between the 3D-CAM-S and the traditional CAM-S SF using weighted kappa statistics. RESULTS A method for scoring severity using 3D-CAM items was developed that achieved good agreement with the CAM-S SF in the derivation dataset (κ = 0.94, 95% confidence interval (CI) = 0.93-0.95). The 3D-CAM-S achieved nearly identical agreement in the independent validation dataset (κ = 0.93, 95% CI = 0.92-0.95), and 100% of 3D-CAM-S scores were within 1 point of the CAM-S SF score in both datasets. The 3D-CAM-S also strongly predicts clinical outcomes. CONCLUSION A newly developed method for scoring delirium severity using the 3D-CAM (the 3D-CAM-S) has excellent agreement with the CAM-S SF. This new methodology enables clinicians and researchers using the 3D-CAM for surveillance to measure delirium severity and monitor its course simultaneously by tracking changes over time. The 3D-CAM-S expands the utility of the 3D-CAM as an important tool for delirium recognition and management.

Abstract
BACKGROUND The symptom profile of alcohol withdrawal delirium (AWD), relative to deliriums of other etiology, remains uncertain. OBJECTIVE To evaluate the factor structure of symptoms in patients with AWD, as assessed by the Delirium Rating Scale-Revised-98 (DRS-R-98). METHOD A total of 112 patients aged 18 years or more with AWD were assessed on DRS-R-98. RESULTS The mean age of participants was 44.2 years. About two-third of the patients developed delirium within 24 hours of the last intake of alcohol and the mean duration of delirium at the time of assessment was 3.9 days. In 46% of cases the delirium was attributed solely to alcohol withdrawal; in the remaining subjects alcohol withdrawal was a major contributory factor. Three separate principal component analysis (whole sample, pure AWD and AWD with associated etiologies) were carried out. In all the factor analyses, one of the factors included cognitive symptoms (attention, orientation and visuospatial disturbances) along with or without short- and long-term memory impairment; the second factor included motoric symptoms along with sleep-wake cycle disturbances; the third factor included psychotic symptoms. For the whole group and subgroup of AWD with associated etiologies, items of higher level thinking (i.e. language disturbances and thought process abnormality) loaded along with cognitive symptoms. In pure AWD group, these items along with memory disturbances loaded with psychotic symptoms. CONCLUSIONS Results of the current factor analyses suggest that the factor structure of pure AWD is different from AWD with associated etiologies. Hence, attention to the symptom profile of patients with AWD may provide clues to delirium etiology.

Abstract
OBJECTIVE To identify scales that can establish a quantitative assessment of delirium symptoms in critically ill patients through a systematic review. METHODS Studies that evaluated delirium stratification scales in patients hospitalized in intensive care units were selected in a search performed in the MedLine database. Validation studies of these scales and their target patient populations were analyzed, and we identified the examiner and the signs and symptoms evaluated. In addition, the duration of the application and the sensitivity and specificity of each scale were assessed. RESULTS Six scales were identified: the Delirium Detection Score, the Cognitive Test of Delirium, the Memorial Delirium Assessment Scale, the Intensive Care Delirium Screening Checklist, The Neelon and Champagne Confusion Scale and the Delirium Rating Scale-Revised-98. CONCLUSION The scales identified allow the stratification and monitoring of critically ill patients with delirium. Among the six scales, the most studied and best suited for use in the intensive care units was the Intensive Care Delirium Screening.

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
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 Assessment of delirium is performed with a variety of instruments, making comparisons between studies difficult. A conversion rule between commonly used instruments would aid such comparisons. The present study aimed to compare the revised Delirium Rating Scale (DRS-R98) and Memorial Delirium Assessment Scale (MDAS) in a palliative care population and derive conversion rules between the two scales. METHOD Both instruments were employed to assess 77 consecutive patients with DSM-IV delirium, and the measures were repeated at three-day intervals. Conversion rules were derived from the data at initial assessment and tested on subsequent data. RESULTS There was substantial overall agreement between the two scales [concordance correlation coefficient (CCC) = 0.70 (CI 95 = 0.60-0.78)] and between most common items (weighted κ ranging from 0.63 to 0.86). Although the two scales overlap considerably, there were some subtle differences with only modest agreement between the attention (weighted κ = 0.42) and thought process (weighted κ = 0.61) items. The conversion rule from total MDAS score to DRS-R98 severity scores demonstrated an almost perfect level of agreement (r = 0.86, CCC = 0.86; CI 95 = 0.79-0.91), similar to the conversion rule from DRS-R98 to MDAS. SIGNIFICANCE OF RESULTS Overall, the derived conversion rules demonstrated promising accuracy in this palliative care population, but further testing in other populations is certainly needed.

Abstract
AIM The aim of this study was to determine the correlation between delirium motor subtypes and other symptoms of delirium. METHODS Three hundred and twenty-one (n = 321) consecutive patients referred to consultation-liaison psychiatry services were evaluated on Delirium Rating scale-Revised-98 version and amended Delirium Motor Symptom Scale. RESULTS Half of the patients had hyperactive subtype (n = 161; 50.15%) delirium. One-quarter of the study sample met the criteria for mixed subtype (n = 79; 24.61%), about one-fifth of the study sample met the criteria for hypoactive delirium subtype (n = 64; 19.93%), and only very few patients (n = 17; 5.29%) did not meet the required criteria for any of these three subtypes and were categorized as 'no subtype'. When the hyperactive and hypoactive subtypes were compared, significant differences were seen in the prevalence of perceptual disturbances, delusions, lability of affect, thought process abnormality, motor agitation and motor retardation. All the symptoms were more common in the hyperactive subtype except for thought process abnormality and motor retardation. Compared to hyperactive subtype, the mixed subtype had significantly higher prevalence of thought process abnormality and motor retardation. Significant differences emerged with regard to perceptual disturbances, delusions, lability of affect and motor agitation when comparing the patients with mixed subtype with those with hypoactive subtype. All these symptoms were found to be more common in the mixed subtype. No significant differences emerged for the cognitive symptoms as assessed on Delirium Rating scale-Revised-98 across the different motoric subtypes. CONCLUSION Different motoric subtypes of delirium differ on non-cognitive symptoms.

Abstract
AIM To assess the incidence, prevalence, risk factors and outcome of delirium in patients admitted to a cardiac intensive care unit (ICU) of a tertiary care hospital. METHODS Three hundred nine consecutive patients admitted to a 22-bed coronary care unit were screened for presence of delirium by using Confusion Assessment Method for Intensive Care Unit (CAM-ICU), and those found positive on CAM-ICU were further evaluated by a psychiatrist to confirm the diagnosis of delirium as per DSM-IV-TR criteria. Patients were also evaluated for the risk factors for delirium and outcome of delirium. RESULTS Incidence rate of delirium was 9.27%, and prevalence rate was 18.77%. The risk factors identified for delirium in binary logistic regression analysis were hypokalemia, Sequential Organ Failure Assessment score, presence of cognitive deficits, receiving more than three medications, sepsis, hyponatremia, presence of cardiogenic shock, having undergone coronary artery bypass grafting, left ventricular ejection fraction <30, currently receiving opioids, age more than 65 years, presence of diabetes mellitus, presence of uncontrolled diabetes mellitus, history of seizures, presence of congestive cardiac failure, having undergone angioplasty, presence of atrial fibrillation, ongoing depression, currently receiving/taking benzodiazepines, warfarin, ranitidine, steroids, non-steroidal anti-inflammatory drugs, higher total number of medications, presence of raised creatinine, anaemia, hypoglycemia, Acute Physiology and Chronic Health Evaluation II score and Charlson Comorbidity Index score. About one fourth (n=22; 27%) of the patients who developed delirium died during the hospital stay in contrast to 1% mortality in the non-delirious group. Those with delirium also had longer stay in the ICU. CONCLUSIONS Delirium is highly prevalent in the cardiac ICU setting and is associated with presence of many modifiable risk factors. Development of delirium increases the mortality risk and is associated with longer cardiac ICU 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
Over the years Consultation-Liaison (C-L) psychiatry has contributed significantly to the growth of the psychiatry and has brought psychiatry very close to the advances in the medicine. It has also led to changes in the medical education and in the providing comprehensive management to the physically ill. In India, although the General Hospital Psychiatric units were established in 1930s, C-L Psychiatry has never been the main focus of training and research. Hence there is an urgent need to improve C-L Psychiatry services and training to provide best and optimal care to the patients and provide best education to the trainees.

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
OBJECTIVE Delirium is a common, difficult-to-diagnose clinical condition in critical care units. The lack of recognition of delirium often results in increased morbidity and mortality. The study aimed to determine the validity and reliability of the Intensive Care Delirium Screening Checklist (ICDSC) in a resource-poor medical intensive care setting in South India. MATERIALS AND METHODS Fifty-three patients admitted into the medical intensive care unit of a teaching hospital who were neither mute nor intubated were recruited for the study. Trained residents administered the ICDSC to screen for delirium. A consultant psychiatrist used the International Classification of Diseases, 10th Revision diagnostic criteria for research to determine the presence of delirium. RESULTS The optimal threshold for screening, as ICDSC total score of 3 or more, was obtained by using a receiver operating characteristic curve. Although a sensitivity and specificity of 75% and 74%, respectively, were obtained at the original cutoff of 4, a sensitivity of 90% and specificity of 61.54% were achieved with a cutoff of 3. In a subsample of 21 patients, interrater reliability was evaluated and found to be 0.947 (95% confidence interval, 0.870-0.979). The ICDSC had good internal consistency, with Cronbach α of .754 and Guttman split-half coefficient of 0.71. Factor analysis revealed a 2-factor structure, namely, altered sensorium/psychopathology and sleep-wake cycle problems. CONCLUSIONS Our findings indicate that in nonintubated intensive care unit patients, the ICDSC can be used to screen for delirium but should not be used as a diagnostic instrument in this patient population and that residents can be trained in the use of the instrument in resource-poor critical care settings. Using a different threshold for positivity of 3 rather than 4 appeared to offer improved screening characteristics in this resource-poor critical care setting.

Abstract
Delirium, though quite often referred to psychiatrists for management, does not find many takers for analysis, research and publications. Acute in onset, multiplicity of etiology and manifestations, high risk of mortality delirium is very rewarding in proper management and outcome. Delirium has a limited agenda on teaching programs, research protocols and therapeutic strategies. There is a dearth of Indian studies both in international and national scientific literature. This annotation is based on a Medline search for "delirium India" on Pubmed, which resulted in 54 articles. A search in Indian Journal of Psychiatry for "delirium" resulted in 38 published articles, "delirium tremens" showed up only five articles. The articles are primarily from the Indian Journal of Psychiatry with cross reference to articles on Pubmed or Google search on Indian studies and a few international studies.
