Abstract
BACKGROUND Biological sex influences the risk of depression and cognitive impairment, but its role in relation to postoperative delirium is unclear. This analysis investigates sex differences in delirium risk after coronary artery bypass graft (CABG) surgery and sex-related differences in relation to affective and cognitive symptoms. METHODS This is a secondary analysis of the Neuropsychiatric Outcomes After Heart Surgery (NOAHS) study, a single-site, observational study of a CABG surgery cohort (n = 149). Preoperative characteristics are stratified by sex, and baseline variables that differ by sex are evaluated to understand whether sex modifies their relationships with delirium. We also evaluate sex differences in one-month depression and cognition. RESULTS Female sex is associated with several delirium risk factors, including higher risk of preoperative depression and middle cerebral artery (MCA) stenosis. MCA stenosis was statistically associated with delirium only among women (OR 15.6, 95% CI 1.5, 164.4); mild cognitive impairment (MCI) was associated with delirium only in men (OR 4.6, 95% CI 1.2, 17.9). Other sex-based differences failed to reach statistical significance. Depression remained commoner among women 1 month post-CABG. CONCLUSIONS Women in this CABG cohort were more likely to have depression at baseline and 1 month postoperatively, as well as MCA stenosis and postoperative delirium. Sex might modify the relationship between post-CABG delirium and its risk factors including MCA stenosis and MCI. Cerebrovascular disease deserves study as a potential explanation linking female sex and a range of poor outcomes among women with coronary heart disease.

Abstract
Objective: Proactive consultation-liaison (C-L) psychiatry aims to meet the mental health needs of medical-surgical populations-many of which go unmet by the conventional C-L model-through systematic screening and integrated care. We implemented an automated screening list to enhance case identification of an existing proactive C-L service and evaluated service metrics along with clinician- and patient-reported outcomes. Methods: Service outcomes were evaluated using historical and contemporary comparison data. Adjusted difference-in-difference analyses were used to determine change in consult characteristics, mean length of stay (LOS), and scores on Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS). Practitioners and nurses were surveyed regarding service satisfaction, perceived safety, and burnout. Results: During the intervention, the consult rate was 3-fold higher than at baseline. Change in time to consultation was equivocal. Overall mean LOS was not reduced, but observed LOS was 1.2 days shorter than expected among non-COVID patients receiving psychiatric consultation (P = not significant). Mean patient-rated hospital satisfaction on HCAHPS was 1 point higher on intervention units during the intervention. Surveys revealed broad satisfaction with this model among practitioners and improved perception of safety among nurses. Conclusions: Proactive C-L psychiatry enhanced by automated screening was associated with improved service utilization and evidence suggestive of LOS reduction among those most likely to receive direct benefit from this model of care. Further, both patient and clinician ratings were improved during the intervention. Proactive C-L psychiatry provides benefits to patients, clinicians, and health systems and may be poised to achieve the Triple Aim in health care. Prim Care Companion CNS Disord 2024;26(2):23m03647.

Requesting That Delirium Achieve Parity With Acute Encephalopathy in the MS-DRG System. J Acad Consult Liaison Psychiatry 2024:S2667-2960(24)00024-7. [PMID: 38503671 DOI: 10.1016/j.jaclp.2024.02.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/22/2023] [Revised: 02/08/2024] [Accepted: 02/18/2024] [Indexed: 03/21/2024]
Abstract
Since 2007, the Medicare Severity Diagnosis Related Groups classification system has favored billing codes for acute encephalopathy over delirium codes in determining hospital reimbursement and several quality-of-care value metrics, despite broad overlap between these sets of diagnostic codes. Toxic and metabolic encephalopathy codes are designated as major complication or comorbidity, whereas causally specified delirium codes are designated as complication or comorbidity and thus associated with a lower reimbursement and lesser impact on value metrics. The authors led a submission to the U.S. Centers for Medicare and Medicaid Services requesting that causally specified delirium be designated major complication or comorbidity alongside toxic and metabolic encephalopathy. Delirium warrants reclassification because it satisfies U.S. Centers for Medicare and Medicaid Services' guiding principles for re-evaluating Medicare Severity Diagnosis Related Group severity levels. Delirium: (1) has a bidirectional relationship with the permanent condition of dementia (major neurocognitive disorder per DSM-5-TR), (2) indexes vulnerability across populations, (3) impacts healthcare systems across levels of care, (4) complicates postoperative recovery, (5) consigns patients to higher levels of care, (6) impedes patient engagement in care, (7) has several recent treatment guidelines, (8) often indicates neuronal/brain injury, and (9) represents a common expression of terminal illness. The proposal's impact was explored using the 2019 National Inpatient Sample, which suggested that increasing delirium's complexity designation would lead to an upcoding of less than 1% of eligible discharges. Parity for delirium is essential to enhancing awareness of delirium's clinical and economic costs. Appreciating delirium's impact would encourage delirium prevention and screening efforts, thereby mitigating its dire outcomes for patients, families, and healthcare systems.

Mental health and transcatheter aortic valve replacement: A scoping systematic review. Gen Hosp Psychiatry 2024; 86:10-23.

Abstract
OBJECTIVE To systematically review the literature on mental health symptoms before and after transcatheter aortic valve replacement (TAVR) and describe reported clinical associations with these symptoms. METHODS Using the Preferred Reporting Items for Systematic reviews and Meta-Analysis extension for Scoping Reviews (PRISMA-ScR) guidelines, we reviewed studies involving pre- or post-TAVR mental health assessments or psychiatric diagnoses. RESULTS Eighteen studies were included. Before TAVR, clinically significant depression and anxiety prevalence is 15-30% and 25-30%, respectively, with only a third of these meeting diagnostic thresholds. These symptoms generally improve over the year post-TAVR. Depression is associated with functional impairment, multimorbidity, and lower physical activity; few associations have been described in relation to anxiety. Inconsistent evidence finds depression associated with post-TAVR mortality. One notable study found persistent depression independently predictive of 12-month mortality, and another found depression and cognition to have additive value in predicting mortality risk. CONCLUSIONS Mental health symptoms occur in a significant proportion of the TAVR population. Although symptoms tend to improve, the associations with depression, particularly persistent depression, call for further investigation to examine their associated outcomes. Research is also needed to understand the relationships between mental health conditions and cognition in TAVR-related outcomes.

Abstract
BACKGROUND Manually screening for mental health needs in acute medical-surgical settings is thorough but time-intensive. Automated approaches to screening can enhance efficiency and reliability, but the predictive accuracy of automated screening remains largely unknown. OBJECTIVE The aims of this project are to develop an automated screening list using discrete form data in the electronic medical record that identify medical inpatients with psychiatric needs and to evaluate its ability to predict the likelihood of psychiatric consultation. METHODS An automated screening list was incorporated into an existing manual screening process for 1 year. Screening items were applied to the year's implementation data to determine whether they predicted consultation likelihood. Consultation likelihood was designated high, medium, or low. This prediction model was applied hospital-wide to characterize mental health needs. RESULTS The screening items were derived from nursing screens, orders, and medication and diagnosis groupers. We excluded safety or suicide sitters from the model because all patients with sitters received psychiatric consultation. Area under the receiver operating characteristic curve for the regression model was 84%. The two most predictive items in the model were "3 or more psychiatric diagnoses" (odds ratio 15.7) and "prior suicide attempt" (odds ratio 4.7). The low likelihood category had a negative predictive value of 97.2%; the high likelihood category had a positive predictive value of 46.7%. CONCLUSIONS Electronic medical record discrete data elements predict the likelihood of psychiatric consultation. Automated approaches to screening deserve further investigation.

Describing the features of catatonia: A comparative phenotypic analysis. Schizophr Res 2024; 263:82-92. [PMID: 35995651 PMCID: PMC9938840 DOI: 10.1016/j.schres.2022.08.002] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Revised: 08/04/2022] [Accepted: 08/05/2022] [Indexed: 10/15/2022]
Abstract
BACKGROUND Catatonia is widely under-detected, and the many differences across catatonia rating scales and diagnostic criteria could be a key reason why clinicians have a hard time knowing what catatonia looks like and what constitutes each of its features. METHODS This review begins by discussing the nature of catatonia diagnosis, its evolution in ICD and DSM, and different approaches to scoring. The central analysis then provides a descriptive survey of catatonia's individual signs across scales and diagnostic criteria. The goal of this survey is to characterize distinctions across scales and diagnostic criteria that can introduce variance into catatonia caseness. RESULTS Diagnostic criteria for catatonia in DSM-5-TR and ICD-11 are broadly aligned in terms of which items are included, item definitions and number of items required for diagnosis; however, the lack of item thresholds is a fundamental limitation. Many distinctions across scales and criteria could contribute to diagnostic discordance. DISCUSSION Clear, consistent definitions for catatonia features are essential for reliable detection. Of available scales, Bush-Francis and Northoff can be converted to diagnostic criteria with limited modification. Bush-Francis is the most efficient, with a screening instrument, videographic resources and standardized clinical assessment. Northoff offers the most detailed assessment and uniquely emphasizes emotional and volitional disturbances in catatonia. CONCLUSIONS The field's understanding of the catatonia phenotype has advanced considerably over the past few decades. However, this review reveals many important limitations in the ICD and DSM as well as differences across scales and criteria that stand in the way of reliable catatonia detection.

Abstract
BACKGROUND Delirium, a common syndrome with heterogeneous etiologies and clinical presentations, is associated with poor long-term outcomes. Recording and analyzing all delirium equally could be hindering the field's understanding of pathophysiology and identification of targeted treatments. Current delirium subtyping methods reflect clinically evident features but likely do not account for underlying biology. METHODS The Delirium Subtyping Initiative (DSI) held three sessions with an international panel of 25 experts. RESULTS Meeting participants suggest further characterization of delirium features to complement the existing Diagnostic and Statistical Manual of Mental Disorders Fifth Edition Text Revision diagnostic criteria. These should span the range of delirium-spectrum syndromes and be measured consistently across studies. Clinical features should be recorded in conjunction with biospecimen collection, where feasible, in a standardized way, to determine temporal associations of biology coincident with clinical fluctuations. DISCUSSION The DSI made recommendations spanning the breadth of delirium research including clinical features, study planning, data collection, and data analysis for characterization of candidate delirium subtypes. HIGHLIGHTS Delirium features must be clearly defined, standardized, and operationalized. Large datasets incorporating both clinical and biomarker variables should be analyzed together. Delirium screening should incorporate communication and reasoning.

Abstract
OBJECTIVE Although delirium is well known to acute care clinicians, the features required for its diagnosis and how to understand and operationalize them remain sticking points in the field. To clarify the delirium phenotype, we present a close reading of past and current sets of delirium diagnostic criteria. METHODS We first differentiate the delirium syndrome (i.e., features evaluated at bedside) from additional criteria required for diagnosis. Next, we align related features across diagnostic systems and examine them in context to determine intent. Where criteria are ambiguous, we review common delirium instruments to illustrate how they have been interpreted. RESULTS An acute disturbance in attention is universally attested across diagnostic systems. A second core feature denotes confusion and has been included across systems as disturbance in awareness, impaired consciousness, and thought disorganization. This feature may be better understood as a disturbance in thought clarity and operationalized in terms of neuropsychological domains thereby clearly linking it to global neurocognitive disturbance. Altered level of activity describes a third core feature, including motor and sleep/wake cycle disturbances. Excluding stupor (wherein mental content cannot be assessed due to reduced arousal) from delirium, as in DSM-5-TR, is appropriate for a psychiatric diagnosis, but the brain injury exclusion in ICD-11 is unjustified. CONCLUSIONS The delirium phenotype involves a disturbance in attention, qualitative thought clarity, and quantitative activity level, including in relation to expected sleep/wake cycles. Future diagnostic systems should include a severity threshold and specify that delirium diagnosis refers to a 24-h period.

Abstract
Recognizing that very few potential reviewers and authors receive formal training on peer review, we provide guidance on peer reviewing manuscripts and on being responsive to reviewer comments. Peer review provides benefits to all parties involved. Serving as a peer reviewer gives perspective on the editorial process, fosters relationships with journal editors, gives insights into novel research, and provides a means of demonstrating topical expertise. When responding to peer reviewers, authors have the opportunity to strengthen the manuscript, sharpen the message, and address areas of potential misunderstanding. First, we provide guidance on how to peer review a manuscript. Reviewers should consider the importance of the manuscript, its rigor, and clarity of presentation. Reviewer comments should be as specific as possible. They should also be constructive and respectful in tone. Reviews typically include a list of major comments focused on methodology and interpretation and may also include a list of minor comments that pinpoint specific areas of clarification. Opinions expressed as comments to the editor are confidential. Second, we provide guidance on being responsive to reviewer comments. Authors are encouraged to approach reviewer comments as a collaboration and to view this exercise as an opportunity to strengthen their work. Response comments should be presented respectfully and systematically. The author's goal is to signal that they have engaged directly and thoughtfully with each comment. In general, when an author has questions regarding reviewer comments or how to respond, they are invited to contact the editor to review.

Abstract
OBJECTIVE Depression in patients undergoing coronary artery graft bypass (CABG) surgery is associated with morbidity and mortality, making its early identification and clinical management crucial. Vasculopathy and older age, hallmarks of patients requiring CABG, are also features of vascular depression. In this study, we assess for features of vascular depression in patients undergoing CABG surgery. METHODS This is a cross-sectional analysis of a single-site prospective observational cohort study of patients undergoing CABG surgery. Subjects were assessed preoperatively using the Depression Interview and Structured Hamilton (DISH), depression scales, transcranial Doppler, neuropsychological testing, and clinical dementia rating (CDR). RESULTS Of 161 subjects (mean age 66.2 ± 9.3, female 25%) who completed DISH, 18 had major or minor depression, 17 of whom had a past history of major or minor depression (mean age of onset 35.8 years-old). Pre-CABG depression was associated with greater functional impairment on CDR Sum of Boxes (OR = 3.7, 95% CI: 1.4, 9.7) and worse performance on letter fluency test (OR = 0.90, 95% CI: 0.81, 0.99) and trail-making tests (A: OR = 1.06, 95% CI: 1.01, 1.12; B: OR 1.02, 95% CI: 1.01, 1.04). Pre-CABG depression was not associated with middle cerebral artery (MCA) stenosis. CONCLUSIONS Pre-CABG depression is associated with cognitive and functional impairment similar to vascular depression, but we did not find evidence of an association with older age of onset and MCA stenosis. Further studies on white matter disease in this population are needed to examine the vascular depression hypothesis for pre-CABG depression.

Abstract
An interdisciplinary plenary session entitled "Rethinking and Rehashing Delirium" was held during the 2021 Annual Meeting of the Academy of Consultation-Liaison Psychiatry to facilitate dialog on the prevalent approach to delirium. Panel members included a psychiatrist, neurointensivist, and critical care specialist, and attendee comments were solicited with the goal of developing a statement. Discussion was focused on a reappraisal of delirium and, in particular, its disparate terminology and history in relation to acute encephalopathy. The authors endorse a recent joint position statement that describes acute encephalopathy as a rapidly evolving (<4 weeks) pathobiological brain process that presents as subsyndromal delirium, delirium, or coma and suggest the following points of refinement: (1) to suggest that "delirium disorder" describe the diagnostic construct including its syndrome, precipitant(s), and unique pathophysiology; (2) to restrict the term "delirium" to describing the clinical syndrome encountered at the bedside; (3) to clarify that the disfavored term "altered mental status" may occasionally be an appropriate preliminary designation where the diagnosis cannot yet be specified further; and (4) to provide rationale for rejecting the terms acute brain injury, failure, or dysfunction. The final common pathway of delirium appears to involve higher-level brain network dysfunction, but there are many insults that can disrupt functional connectivity. We propose that future delirium classification systems should seek to characterize the unique pathophysiological disturbances ("endotypes") that underlie delirium and delirium's individual neuropsychiatric symptoms. We provide provisional means of classification in hopes that novel subtypes might lead to specific intervention to improve patient experience and outcomes. This paper concludes by considering future directions for the field. Key areas of opportunity include interdisciplinary initiatives to harmonize efforts across specialties and settings, enhance underrepresented groups in research, integration of delirium and encephalopathy in coding, development of relevant quality and safety measures, and exploration of opportunities for translational science.

Abstract
The British Association for Psychopharmacology developed an evidence-based consensus guideline on the management of catatonia. A group of international experts from a wide range of disciplines was assembled. Evidence was gathered from existing systematic reviews and the primary literature. Recommendations were made on the basis of this evidence and were graded in terms of their strength. The guideline initially covers the diagnosis, aetiology, clinical features and descriptive epidemiology of catatonia. Clinical assessments, including history, physical examination and investigations are then considered. Treatment with benzodiazepines, electroconvulsive therapy and other pharmacological and neuromodulatory therapies is covered. Special regard is given to periodic catatonia, malignant catatonia, neuroleptic malignant syndrome and antipsychotic-induced catatonia. There is attention to the needs of particular groups, namely children and adolescents, older adults, women in the perinatal period, people with autism spectrum disorder and those with certain medical conditions. Clinical trials were uncommon, and the recommendations in this guideline are mainly informed by small observational studies, case series and case reports, which highlights the need for randomised controlled trials and prospective cohort studies in this area.

Abstract
IMPORTANCE Despite discrete etiologies leading to delirium, it is treated as a common end point in hospital and in clinical trials, and delirium research may be hampered by the attempt to treat all instances of delirium similarly, leaving delirium management as an unmet need. An individualized approach based on unique patterns of delirium pathophysiology, as reflected in predisposing factors and precipitants, may be necessary, but there exists no accepted method of grouping delirium into distinct etiologic subgroups. OBJECTIVE To conduct a systematic review to identify potential predisposing and precipitating factors associated with delirium in adult patients agnostic to setting. EVIDENCE REVIEW A literature search was performed of PubMed, Embase, Web of Science, and PsycINFO from database inception to December 2021 using search Medical Subject Headings (MeSH) terms consciousness disorders, confusion, causality, and disease susceptibility, with constraints of cohort or case-control studies. Two reviewers selected studies that met the following criteria for inclusion: published in English, prospective cohort or case-control study, at least 50 participants, delirium assessment in person by a physician or trained research personnel using a reference standard, and results including a multivariable model to identify independent factors associated with delirium. FINDINGS A total of 315 studies were included with a mean (SD) Newcastle-Ottawa Scale score of 8.3 (0.8) out of 9. Across 101 144 patients (50 006 [50.0%] male and 49 766 [49.1%] female patients) represented (24 015 with delirium), studies reported 33 predisposing and 112 precipitating factors associated with delirium. There was a diversity of factors associated with delirium, with substantial physiological heterogeneity. CONCLUSIONS AND RELEVANCE In this systematic review, a comprehensive list of potential predisposing and precipitating factors associated with delirium was found across all clinical settings. These findings may be used to inform more precise study of delirium's heterogeneous pathophysiology and treatment.

Abstract
BACKGROUND Chronic cerebral hypoperfusion is a potential mechanism that causes cognitive impairment in patients with heart failure. Cognitive impairment in this population is associated with an increased mortality and poorer quality of life. Understanding the etiopathogenesis of cognitive impairment is crucial to developing effective treatment. A left ventricular assist device (LVAD) is a durable mechanical circulatory support device that restores systemic perfusion in patients with heart failure, potentially reversing cerebral hypoperfusion and cognitive impairment. OBJECTIVE This case series and systematic review examines the effect of LVAD implantation on cognition in patients with heart failure. METHODS We report a case series of 4 LVAD recipients at a tertiary academic center who underwent preimplant and postimplant cognitive testing. We also conducted a systematic review of studies with adult recipients of a continuous-flow LVAD whose cognition was measured before and after implantation. We searched Medline, EMBASE, SCOPUS, and the Cochrane library (start of database to July 16, 2021) for longitudinal, peer-reviewed studies written in English. RESULTS Cognitive improvement after LVAD implantation was observed in the case series, with improvement on phonemic fluency and digit symbol coding assessments. Two out of 4 cases in the case series improved on Clinical Dementia Rating: one from moderate dementia to mild cognitive impairment and another from mild cognitive impairment to unimpaired. Seven studies were included in the systematic review and were heterogeneous regarding cognitive tests employed, follow-up period, and measured outcomes. Montreal Cognitive Assessment and Trail-Making Test Part B were used most commonly. Cognitive improvement was reported in all 7 studies with at least 1 study reporting statistically significant improvements in each the following cognitive domains: delayed and immediate recall, executive function, visuospatial function, verbal function, attention, and processing speed. Most studies had small sample sizes and lacked a control group. CONCLUSIONS LVAD implantation appears to be associated with improved cognition. Adequately powered, prospective studies are needed to examine the effect of LVAD on cognitive function in patients with heart failure. Additionally, studies that directly examine cerebral blood flow in conjunction with cognitive assessment are needed to establish the relationship between the reversal of cerebral hypoperfusion and improved cognition.

Abstract
OBJECTIVE Catatonia is widely underdiagnosed, in large part due to inaccurate recognition of its specific features. This study aimed to evaluate the effectiveness of an online educational module to improve theoretical and practical knowledge of the Bush-Francis Catatonia Rating Scale (BFCRS) across a broad range of clinicians and medical students. METHOD A 1-h online module, including a training manual and videos, was disseminated to medical students, psychiatry residents and fellows, and psychiatrists through national Listservs and through the Academy of Consultation-Liaison Psychiatry. Participants completed pre- and post-module testing consisting of a 50-question multiple-choice test and a 3-min standardized patient video scored using the 23-item BFCRS. Participants accessed the module from October 1, 2020, to April 4, 2021. Immediate improvement and 3-month knowledge retention were assessed using quantitative and qualitative analyses. RESULTS Study enrollment was high with moderate dropout (pre-testing: n = 482; post-testing: n = 236; 3-month testing: n = 105). Adjusting for demographics, large pre-post improvements were found in performance (multiple-choice: 11.3 points; standardized patient scoring: 4.2 points; both p < 0.001) and for nearly all individual BFCRS items. Knowledge attrition was modest, and improvements persisted at 3 months. CONCLUSIONS This educational resource provides descriptive and demonstrative reference standards of the items on the BFCRS. This curriculum improved identification of catatonia's features on both multiple choice and standardized patient scoring across all ages and training levels with good overall knowledge retention.

Abstract
OBJECTIVE The first objective of this review is to explore the factors that have led to and maintain the division between delirium and acute encephalopathy. The second is to explore the value of harmonizing them through the model of delirium disorder. METHOD This narrative review outlines major distinctions between delirium and acute encephalopathy. It also compares them with the model of delirium disorder, which seeks not only to integrate them but also to offer a broader palette of treatment targets. RESULTS Delirium implies an underlying acute encephalopathy, whereas acute encephalopathy presents as a spectrum from subsyndromal delirium to coma. Key factors that differentiate these two models include tradition, nuances of the models themselves, linguistic connotations, evoked responses from clinicians, implications of preventability and responsibility, cultural perceptions of non-pharmacological vs pharmacological interventions and economic incentives. A validated set of pathophysiological subtypes may ultimately help link the delirium-spectrum phenotype with various acute encephalopathies. CONCLUSIONS Developing a coherent clinical and scientific approach to this set of conditions demands that we first develop a coherent understanding of the conditions themselves and how they relate to one another. Such an approach must embrace the tension between a convergent phenotype and its diverse biological underpinnings.

Abstract
Background: Catatonia is often overlooked, and a key factor for underdiagnosis may be an inadequate understanding of catatonia's heterogeneous phenotypes. The aim of this study was to identify the current state of theoretical and applied knowledge of catatonic features among psychiatry trainees and practitioners using the Bush-Francis Catatonia Rating Scale (BFCRS), the most commonly used instrument to identify and score catatonia. Methods: We created an online 50-item multiple-choice test and 3-minute standardized patient video to be scored using the BFCRS. Email invitations were sent to medical students and psychiatry residents and fellows through listservs of psychiatry clerkship and residency directors and to consultation-liaison psychiatrists through the Academy of Consultation-Liaison Psychiatry. Participants could access the exam from October 1 to December 31, 2020. Results: In our sample (n = 482), participants correctly answered an average of 55% of test questions and identified 69% of BFCRS items on the standardized patient exam. Multivariable regression adjusting for demographics revealed that, compared to medical students, psychiatrists scored 7 points higher on the multiple-choice test and identified only 2 more items correctly on the BFCRS. Older participants performed worse than younger participants. No meaningful performance differences were identified by region or gender. Several items were consistently misidentified. Conclusions: We found significant inaccuracies in clinicians' understanding of catatonic features irrespective of their stage of training and years of experience. These data suggest prevalent gaps in catatonia recognition among psychiatrists, psychiatry trainees, and medical students utilizing the BFCRS. This has important implications for clinical research and patient care.

Abstract
BACKGROUND Proactive consultation-liaison (C-L) psychiatry has been shown to reduce hospital length of stay (LOS), increase psychiatric C-L consult rate, and improve hospital staff satisfaction. Nursing attrition has not been studied in relation to proactive C-L. OBJECTIVE Our primary aim in evaluating the proactive C-L service called Proactive Integration of Mental Health Care in Medicine (PRIME Medicine) is to analyze change in LOS over 10 months using historical and contemporary comparison cohorts. As secondary aims, we assess change in psychiatric consultation rate, time to consultation, and change in nurse attrition. METHODS PRIME Medicine was implemented in 3 hospital medicine units as a quality-improvement project. Team members systematically screened patients arriving to assigned units for psychiatric comorbidity. Identified patients were reviewed with hospitalist teams and nurses with the goal of early intervention. RESULTS Including historical and contemporary comparison cohorts, the mean sample age was 62.4 years (n = 8884). Absolute LOS was unchanged, but difference-in-difference analysis trended toward reduced LOS by 0.16 day (P = 0.08). Consultation rate increased from 1.6% (40 consults) to 7.4% (176 consults). Time to consultation was unchanged (4.0-3.8 d). Annual per-unit nursing turnover increased from 4.7 to 5.7 in PRIME units but from 8.5 to 12.0 in comparison units. Nurses citing "population" as the reason for leaving decreased from 2.7 to 1.7 in PRIME units but increased from 1.5 to 4.5 in comparison units. PRIME Medicine led to increased consultation rate, and our unit-wide outcomes provide a conservative estimate of effect. Factors that may have influenced effect size include our cohort's advanced age, considerable emergency department boarding times, increasing proportion of patients discharged to skilled nursing facilities, and concurrent LOS-reduction initiatives on all units. The favorable trends in nursing attrition on PRIME units may be explained in part by our prior finding that PRIME Medicine was associated with enhanced nursing satisfaction. CONCLUSIONS While PRIME Medicine had no more than a modest effect on LOS, it was associated with a markedly increased psychiatric consult rate and favorable trends in nursing retention. This analysis highlights important factors that should be considered when implementing and determining value metrics for a proactive C-L service.

Baseline sleep as a predictor of delirium after surgical aortic valve replacement: A feasibility study. Gen Hosp Psychiatry 2021; 71:43-46.

Abstract
OBJECTIVE The goal is to assess the feasibility of conducting unattended (type II) sleep studies before surgical aortic valve replacement (SAVR) to examine the relationship between baseline sleep measures and postoperative delirium. METHODS This single-site study recruited 18 of 20 study referrals with aortic stenosis undergoing first lifetime SAVR. Subjects completed a home-based type II sleep study. Delirium was assessed postoperative days 1-5. Exact logistic regression was used to determine whether sleep efficiency or apnea/hypopnea index predicts delirium. RESULTS Of 18 study participants, 15 successfully completed a home sleep study (mean age: 71.7 +/- 8.1 years old; 10 male subjects). Five subjects (33.3%) developed delirium. Preliminary analyses found that greater sleep efficiency was associated with a large reduction in delirium odds but was not statistically significant (OR = 0.31, 95% CI: 0.06, 1.03, p = 0.057). The point estimate of the relationship between apnea/hypopnea index and delirium was not similarly sizeable (OR 1.10, 95% CI: 0.35, 3.37, p = 0.85). CONCLUSIONS Our findings suggest that home type II sleep studies before SAVR are feasible, and they support adequately powered studies investigating type II home sleep studies as a predictor of postoperative delirium and other important postsurgical outcomes.

Abstract
OBJECTIVES To perform a scoping literature review of cognitive, psychiatric, and quality of life outcomes in adults undergoing extracorporeal membrane oxygenation for any indication. DATA SOURCES We searched PubMed, EMBASE, Cochrane Library, Web of Science, CINAHL, and PsycINFO from inception to June 2019. STUDY SELECTION Observational studies, clinical trials, qualitative studies, and case series with at least 10 adult subjects were included for analysis. Outcomes of interest consisted of general or domain-specific cognition, psychiatric illness, and quality of life measures that included both mental and physical health. DATA EXTRACTION Study selection, data quality assessment, and interpretation of results were performed by two independent investigators in accordance with the PRISMA statement. DATA SYNTHESIS Twenty-two articles were included in this review. Six described cognitive outcomes, 12 described psychiatric outcomes of which two were qualitative studies, and 16 described quality of life outcomes. Cognitive impairment was detected in varying degrees in every study that measured it. Three studies examined neuroimaging results and found neurologic injury to be more frequent in venoarterial versus venovenous extracorporeal membrane oxygenation, but described a variable correlation with cognitive impairment. Rates of depression, anxiety, and post-traumatic stress disorder were similar to other critically ill populations and were related to physical disability after extracorporeal membrane oxygenation. Extracorporeal membrane oxygenation survivors' physical quality of life was worse than population norms but tended to improve with time, while mental quality of life did not differ significantly from the general population. Most studies did not include matched controls and instead compared outcomes to previously published values. CONCLUSIONS Extracorporeal membrane oxygenation survivors experience cognitive impairment, psychiatric morbidity, and worse quality of life compared with the general population and similar to other survivors of critical illness. Physical disability in extracorporeal membrane oxygenation patients plays a significant role in psychiatric morbidity. However, it remains unclear if structural brain injury plays a role in these outcomes and whether extracorporeal membrane oxygenation causes secondary brain injury.

Depression predicts cognitive and functional decline one month after coronary artery bypass graft surgery (Neuropsychiatric Outcomes After Heart Surgery study). Int J Geriatr Psychiatry 2021; 36:452-460.

Abstract
BACKGROUND Prior research on cognitive and functional outcomes after coronary artery bypass graft (CABG) surgery has largely explored these two domains in isolation. In this study, we assess baseline depression and cognition as risk factors for decline in the Clinical Dementia Rating Sum-of-Boxes (CDR-SB) 1 month post-CABG surgery, which a combined measure of cognition and function. DESIGN The Neuropsychiatric Outcomes After Heart Surgery study is a prospective observational cohort study. SETTING A tertiary care, academic center. PARTICIPANTS Of a total study sample of 148 patients undergoing CABG surgery, 124 (83.8%) completed 1-month follow-up assessment. Mean age was 66.3, 32 (25.8%) female and 112 (90.3%) White. MEASUREMENTS Cognition, function, and depression were assessed on semi-structured clinical interviews. Cognitive and functional status were defined using CDR-SB; mild or major depression was defined by the Hamilton Depression Rating Scale. Additionally, neuropsychological battery was performed at baseline. RESULTS CDR-SB decline occurred in 18 (14.5%) subjects. Older age, depression, baseline CDR-SB, and postoperative delirium were associated with 1-month decline on univariate analysis. Older age (OR 1.1 [1.0-1.2]) and depression (OR 6.2 [1.1-35.0]) remained significant on multivariate regression. In separate models, baseline performance on visual Wechsler memory scale (delayed), Hopkins verbal learning test (immediate and delayed), controlled oral word fluency test, and Trails B predicted CDR-SB decline. CONCLUSION Roughly one in seven patients experienced CDR-SB decline 1 month after CABG surgery. Also, preoperative depression deserves recognition for being a predictor of CDR-SB decline one month post-CABG.

Abstract
In 2019, the American Psychiatric Association Council on Consultation-Liaison (C-L) Psychiatry convened a work group to develop a resource document on proactive C-L psychiatry. A draft of this document was reviewed by the Council in July 2020, and a revised version was approved by this Council in September 2020. The accepted version was subsequently reviewed by the American Psychiatric Association Council on Health Care Systems and Financing in November 2020. The final version was approved by the Joint Reference Committee on November 24, 2020, and received approval for publication by the Board of Trustees on December 12, 2020. This resource document describes the historical context and modern trends that have given rise to the model of proactive C-L psychiatry. Styled as an inpatient corollary to outpatient collaborative care models, proactive C-L provides a framework of mental health care delivery in the general hospital designed to enhance mental health services to a broad range of patients. Its 4 elements include systematic screening for active mental health concerns, proactive interventions tailored to individual patients, team-based care delivery, and care integration with primary teams and services. Studies have found that proactive C-L psychiatry is associated with reduced hospital length of stay, enhanced psychiatric service utilization, reduced time to psychiatric consultation, and improved provider and nurse satisfaction. These favorable results encourage further studies that replicate and build upon these findings. Additional outcomes such as patient experience, health outcomes, and readmission rates deserve investigation. Further studies are also needed to examine a broader array of team compositions and the potential value of proactive C-L psychiatry to different hospital settings such as community hospitals, surgery, and critical care.

Abstract
OBJECTIVE The phenotypes of several psychiatric conditions can very closely resemble delirium; the authors describe such presentations as pseudodelirium. However, because the clinical management of these conditions differs markedly from that of delirium, prompt differentiation is essential. The authors provide an educational review to assist clinicians in identifying and managing psychiatric conditions that may be especially challenging to differentiate from delirium. METHODS Based on clinical experience, the authors identified four psychiatric conditions as among the most difficult to differentiate from delirium: disorganized psychosis, Ganser syndrome, delirious mania, and catatonia. An overview of each condition, description of clinical features, differentiation of specific phenotypes from delirium, and review of clinical management are also provided. RESULTS The thought and behavioral disorganization in disorganized psychosis can be mistaken for the clouded sensorium and behavioral dysregulation encountered in delirium. The fluctuating alertness and apparent confusion in Ganser syndrome resemble delirium's altered arousal and cognitive features. As its name suggests, delirious mania presents as a mixture of hyperactive delirium and mania; additional features may include psychosis, autonomic activation, and catatonia. Both delirium and catatonia have hypokinetic and hyperkinetic variants, and the two syndromes can also co-occur. CONCLUSIONS The clinical presentations of several psychiatric conditions can blend with the phenotype of delirium, at times even co-occurring with it. Detailed evaluation is often required to differentiate such instances of pseudodelirium from delirium proper.

Abstract
BACKGROUND Medical personality change (MPC) is a codable diagnosis (i.e., F07.0) that deserves consideration when a patient is inexplicably no longer "acting like him/herself." Its presentation ranges from subtle to severe and is often characterized by bafflingly poor judgment and impairment in several aspects of a person's life. Despite the global impact that MPC can have on a patient's functioning, occupation, and relationships, this condition receives far less clinical consideration than better known syndromes such as depression or anxiety and is often likely incorrectly formulated as such. OBJECTIVE/METHODS This article provides a clinically focused review of MPC. We review its clinical assessment followed by a review of its subtypes, which we have categorized to reflect the behavioral correlates of known frontotemporal-subcortical circuits. These include the apathetic type (ventromedial prefrontal cortex), the labile and disinhibited types (orbitofrontal cortex), and the aggressive and paranoid types (medial temporal lobes). RESULTS For each of these 3 categories, we describe the clinical presentation and review management strategies. For each category, we focus on 3 common causes for MPC-traumatic brain injury, Huntington disease, and brain tumors-which we have selected because clinical features of MPC due to these conditions generalize to many other etiologies of MPC. CONCLUSIONS MPC warrants clinical attention for the range of dysfunction and distress it can cause. It also deserves further scientific study to better characterize its phenotypes, to tailor instruments for its clinical assessment, and to identify effective treatments.

Abstract
OBJECTIVE Psychiatric comorbidity among hospital medicine patients is common and often complicates care delivery and compromises outcomes. Team-based, proactive consultation-liaison (CL) psychiatry has been shown to reduce hospital length of stay (LOS) and care costs, but staff satisfaction with this model has not been explored in detail. Here we evaluate its impact on hospital medicine provider and nurse satisfaction. METHODS We implemented a team-based proactive CL service that reviews all admitted hospital medicine patients across 3 units for psychiatric comorbidity and provides unit-wide integrated mental health care. Hospital medicine staff completed surveys before and after a 6-month pilot phase: 10-item provider surveys covered resource adequacy, safety, time for healthcare improvements, and burnout; 26-item nurse surveys included the same 10 items plus 8 on behavioral health assessment competency and 8 on intervention competency. Additionally, we characterized psychiatric comorbidity, calculated consultation latency and volume and also average LOS during these 6 months. RESULTS The provider response rate was 57% (20/35 before; 21/37 after) and roughly a third for nurses (32/~90 and 31/~90, respectively). Providers rated 9 of 10 items as improved, including one on burnout. Nursing satisfaction improved similarly but with lower effect sizes. During the pilot (n = 1590), 71% had chart-identified psychiatric comorbidity. Consultation latency decreased by 0.86 days; consultation rate increased nearly 3-fold; and average LOS decreased by 0.33 days. CONCLUSIONS Team-based proactive CL psychiatry enhances provider and nurse satisfaction and may even reduce provider burnout. We also confirmed that this model is associated with reduced average LOS.

Abstract
ObjectiveAs the US population ages and with no definitive delirium treatments on the horizon, the delirium epidemic is on course to expand over the coming decades. Recognizing the import of this condition, a recent position statement from 10 medical societies—among whom the American Academy of Neurology was represented—issued recommendations on preferred nomenclature of delirium and acute encephalopathy: it concluded by preferring both terms. Urgently needed is an integrated model that addresses the near-total segregation of these separate bodies of literature, ideally one that offers an interdisciplinary framework to bring these 2 terms and those who use them together.MethodsWe review the historical forces that have led these terms to diverge and consider the unique benefits of each approach as well as their liabilities when considered in isolation. We then explore the potential implications of integrating these concepts and propose a hybrid model to capitalize on the strengths of both the model of delirium and that of acute encephalopathy.ResultsThe model we propose—delirium disorder—builds on the recommendations of this recent position statement and provides a unifying framework designed to have clinical utility and interdisciplinary appeal. It also broadens the translational landscape by identifying 4 distinct treatment targets: underlying causes, procognitive factors, delirium (phenotype alone), and neurophysiologic targets.ConclusionsThis person-centered model aims to integrate delirium and acute encephalopathy within a single framework and shared nomenclature. It is hoped that this model aids in harmonizing research efforts and advancing clinical practice.

Abstract
BACKGROUND Personality describes an enduring pattern of experiences and behaviors in the interpersonal and social sphere. Several aspects of personality, e.g., defenses, relational dynamics, and reactions, are commonly accentuated in the midst of medical care; therefore, understanding a patient's personality allows the clinician to make informed predictions about how a specific patient may respond to illness and how care interactions might be modified to optimize care engagement and outcomes. OBJECTIVE/METHODS This article provides a brief description of the personalities in the Psychodynamic Diagnostic Manual, Second Edition, and discusses how each one might inform clinical interactions. Two additional personality-like presentations-the traumatized patient and cognitive impairment-are included for clinical utility given their high prevalence in medical settings and their potential for broad impact on clinical relationships. RESULTS Personality-informed care is an approach that incorporates information about the patient's personality into the clinical relationship. It describes what the clinician might say and when, what recommendations to offer and how to frame them, and how to comport oneself while providing care. CONCLUSIONS Personality-informed care operationalizes several aspects of personalized medicine, and it offers a heuristic framework that may facilitate and enhance the implementation of evidence-based care.

Abstract
Objective: The purpose of this study was to evaluate key physical properties of commercially available light devices for the treatment of seasonal or nonseasonal depression and to determine whether the devices met clinical criteria, derived from evidence‐based clinical guidelines, for generating adequate light at a reasonable distance, over a reasonable field of illumination, and with an adequate degree of user acceptability. Methods: Twelve manufacturers loaned or donated 24 light therapy devices: 16 light boxes, one light column, four light‐emitting diode beam devices, and three light visors. Each device was evaluated for spectral power distribution, light dispersion, subjective discomfort from glare, adequacy of diffusion, photopic illuminance (in lumens per square meter [lux]), melanopic illuminance relative to photopic illuminance (efficacy ratio), and blue light hazard relative to melanopic illuminance (protection ratio). Results: Physical properties of emitted light varied widely among devices. Only seven larger light boxes satisfied the three clinical criteria. Some devices advertised as “10,000‐lux” devices produced this intensity only at unreasonably close distances, over a restricted field, or with unacceptable glare or unevenness of illumination. Five other devices emitted light with physical properties whose efficacy is less supported by research, although these devices may be useful for some patients. Conclusions: These results should help clinicians identify appropriate devices for patients seeking light therapy for seasonal or nonseasonal depression. Device selection is key to ensuring that patients receive evidence‐supported doses of light.

Abstract
OBJECTIVE Roughly half of general hospital patients may have a psychiatric issue that impacts care, yet most of these are not recognized during hospital admission. Proactive mental health screening offers an opportunity for timely identification and clinical attention to improve outcomes. METHOD We conducted a PRISMA systematic review of Pubmed, Embase, PsycINFO, and Cochrane Library for proactive models of psychiatric consultation to reduce hospital length of stay (LOS) in adult inpatients. For each study, we evaluated the level of evidence and defined the study sample, means of group allocation, screening process, interventions, and outcomes. RESULTS Of the 12 included studies, the 8 whose screening was informed by clinicians with mental health care expertise or whose providers were integrated with primary services reported a reduction in LOS. Two of these also reported favorable cost-benefit analyses. All positive studies represent versions of either psychiatrists embedded within medical or surgical settings or a multidisciplinary team-based model. CONCLUSIONS Proactive CL psychiatry with clinically-informed screening and integrated care delivery appear to reduce LOS. Further studies are needed to explore a broader range of outcomes, hospital populations beyond hospital medicine, and additional benefits of proactive integrated mental health care in the general hospital.

Abstract
OBJECTIVES To summarize evidence on cognitive outcomes after heart valve surgery; secondary aim, to examine whether aortic and mitral valve surgery are associated with different cognitive outcomes. DESIGN Preferred Reporting Items for Systematic Reviews and Meta-Analyses systematic review and meta-analysis. SETTING Cardiac surgery. PARTICIPANTS Individuals undergoing heart valve surgery. MEASUREMENTS We searched MEDLINE, EMBASE, and PsycINFO for peer-reviewed reports of individuals undergoing heart valve surgery who underwent pre- and postoperative cognitive assessment. Our initial search returned 1,475 articles, of which 12 were included. Postoperative cognitive results were divided into those from 1 week to 1 month (early outcomes, npooled = 450) and from 2 to 6 months (intermediate outcomes; npooled = 722). No studies with longer-term outcomes were identified. RESULTS Subjects had moderate early cognitive decline from baseline (Becker mean gain effect size (ES)=-0.39 ± 0.27) that improved slightly by 2 to 6 months (ES=-0.25 ± 0.38). Individuals undergoing aortic valve surgery-who were older on average than those undergoing mitral valve surgery (68 vs 57)-had greater early cognitive decline than those undergoing mitral valve surgery (ES=-0.68 vs -0.12), but both cohorts had similar decline 2 to 6 months postoperatively (ES=-0.27 vs -0.20). CONCLUSIONS Heart valve surgery is associated with cognitive decline over the 6 months after surgery, but outcomes beyond 6 months are unclear. These findings highlight the cognitive vulnerability of this population, especially older adults with aortic stenosis. © 2018 American Geriatrics Society and Wiley Periodicals, Inc.

Refining Delirium: A Transtheoretical Model of Delirium Disorder with Preliminary Neurophysiologic Subtypes. Am J Geriatr Psychiatry 2018; 26:913-924.

Abstract
The development of delirium indicates neurophysiologic disruption and predicts unfavorable outcomes. This relationship between delirium and its outcomes has inspired a generation of studies aimed at identifying, predicting, and preventing both delirium and its associated sequelae. Despite this, evidence on delirium prevention and management remains limited. No medication is approved for the prevention or treatment of delirium or for its associated psychiatric symptoms. This unmet need for effective delirium treatment calls for a refined approach. First, we explain why a one-size-fits-all approach based on a unitary biological model of delirium has contributed to variance in delirium studies and prevents further advance in the field. Next, in parallel with the shift from dementia to "major neurocognitive disorder," we propose a transtheoretical model of "delirium disorder" composed of interactive elements-precipitant, neurophysiology, delirium phenotype, and associated psychiatric symptoms. We explore how these relate both to the biopsychosocial factors that promote healthy cognition ("procognitive factors") and to consequent neuropathologic sequelae. Finally, we outline a preliminary delirium typology of specific neurophysiologic disturbances. Our model of delirium disorder offers several avenues for novel insights and clinical advance: it univocally differentiates delirium disorder from the phenotype of delirium, highlights delirium neurophysiology as a treatment target, separates the core features of delirium from associated psychiatric symptoms, suggests how procognitive factors influence the core elements of delirium disorder, and makes intuitive predictions about how delirium disorder leads to neuropathologic sequelae and cognitive impairment. Ultimately, this model opens several avenues for modern neuroscience to unravel this disease of antiquity.

Abstract
Delirium (acute confusion) is a serious, common health condition, and it predicts poor outcomes, including greater rates of mortality, institutionalization, prolonged hospitalization, and cognitive impairment. Expedient diagnosis and management are critical to address modifiable delirium causes and improve both quality of care and outcomes. Moreover, more than a third of delirium is preventable. Despite the clear significance of delirium and our increasingly sophisticated understanding of the condition, the gap between evidence and practice persists. The authors provide an educational review of 10 prevalent misconceptions of delirium pertaining to recognition, etiology, natural history, and best management. The authors respond to each with best evidence. Several themes emerge, chief among which is that casual observation is seldom sufficient to detect delirium. Use of open-ended questions, regular neurocognitive testing, and validated delirium screening instruments will aid in accurately identifying cases of delirium. Delirium is typically multifactorial, with several physiological and/or pharmacological contributors. Because of its multidetermined nature and its relationship with cognitive vulnerability, delirium can persist for days to months after acute causes have resolved. Furthermore, patients often have long-term cognitive impairment after delirium rather than returning to their predelirium cognitive baseline. Finally, nonpharmacological management of delirium is first-line, both for prevention and treatment. Psychotropic drugs such as neuroleptics are not recommended for routine use in delirium. They are best reserved for treating dangerous or distressing symptoms, including severe agitation, psychosis, or emotional lability. Challenging these 10 misconceptions stands to improve patient care, quality of life, and clinical outcomes substantially.

Abstract
OBJECTIVE The objective of this review is to determine the probability that catatonia in the hospital has a secondary cause ("medical catatonia") and to calculate the relative proportions of these causes stratified by hospital setting. METHODS PRISMA systematic review of PubMed. RESULTS Eleven studies were included. Hospital-wide, 20% of catatonia was medical. In acute medical and surgical settings, medical catatonia comprised more than half of cases. At least 80% of older adults seen by consult psychiatry and critically ill patients had a medical cause. Two thirds of medical catatonia involved CNS-specific disease including encephalitis, neural injury, developmental disorders, structural brain pathology, or seizures. CONCLUSIONS Patients in acute medical and surgical settings with catatonia deserve a medical workup that prioritizes CNS etiologies.

Abstract
Older adults account for half of intensive care unit (ICU) admissions and ICU days, and approximately 2 in 5 older adults in the ICU have preexisting cognitive impairment (PCI). PCI identification is important for risk stratification and may influence ICU utilization and decision-making surrogacy. PCI is overlooked in more than half of patients without screening; however, screening instruments can identify PCI in less than 5 minutes. Management of PCI in the ICU involves addressing associated neuropsychiatric symptoms. Nonpharmacological interventions should be considered the mainstay of treatment; psychotropics may be considered, although available data on their efficacy is limited.

Impact of Delirium After Hip Fracture Surgery on One-Year Mortality in Patients With or Without Dementia: A Case of Effect Modification. Am J Geriatr Psychiatry 2017; 25:308-315. [PMID: 27838314 PMCID: PMC6197860 DOI: 10.1016/j.jagp.2016.10.008] [Citation(s) in RCA: 46] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/12/2016] [Revised: 10/17/2016] [Accepted: 10/18/2016] [Indexed: 11/29/2022]
Abstract
OBJECTIVES We evaluated whether delirium after hip fracture repair modifies the relationship between baseline dementia and one-year mortality after surgery. METHODS Patients age 65 years and older undergoing hip fracture repair surgery at John Hopkins Bayview Medical Center between 1999 and 2009 were eligible for this prospective cohort study. Baseline probable dementia was defined as either preoperatively diagnosed dementia per geriatrician or score less than 24 on the Mini-Mental State Examination. Delirium was assessed using the Confusion Assessment Method. Four cognitive groups were defined: 1) neither probable dementia nor delirium (NDD), 2) probable dementia only, 3) delirium only, or 4) delirium superimposed on dementia (DSD). Primary outcome of mortality was obtained through hospital records, obituaries, the National Death Index, and Social Security Death Index. RESULTS The current sample comprises 466 subjects (average age: 80.8 ± 7.0 years; 73.6% female). Of these, 77 (17%) were categorized as DSD, 68 (15%) probable dementia only, 73 (16%) delirium only, and 248 (53%) NDD. Cox regression revealed that DSD subjects had a significantly higher hazard of one-year mortality than NDD subjects (hazard ratio [HR]: 1.71, 95% CI: 1.06, 2.77) after adjusting for age, sex, medical comorbidity, and surgery duration. Trends toward greater mortality for probable-dementia and delirium only subjects were not significant (HR: 1.42 [95% CI: 0.80, 2.52] and 1.12 [95% CI: 0.64, 1.95], respectively). CONCLUSIONS Delirium after hip fracture repair surgery in patients with preoperative dementia modifies the risk of mortality over the first postoperative year. Patients with DSD have a nearly two-fold greater odds of one-year mortality than those without dementia or delirium.

Alcohol and Sedative-Hypnotic Withdrawal Catatonia: Two Case Reports, Systematic Literature Review, and Suggestion of a Potential Relationship With Alcohol Withdrawal Delirium. PSYCHOSOMATICS 2015; 57:246-55. [PMID: 26949118 DOI: 10.1016/j.psym.2015.12.007] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/17/2015] [Revised: 12/17/2015] [Accepted: 12/17/2015] [Indexed: 12/14/2022]
Abstract
BACKGROUND Withdrawal from alcohol and sedative-hypnotics can be complicated by seizures, hallucinations, or delirium. Withdrawal catatonia is another, less commonly discussed complication that clinicians should appreciate. METHODS We present a case of alcohol withdrawal catatonia and a case of benzodiazepine withdrawal catatonia and offer a systematic review of previous cases of alcohol or sedative-hypnotic withdrawal catatonia. We outline clinical features that suggest a potential link between withdrawal catatonia and withdrawal delirium. RESULTS We identified 26 cases of withdrawal catatonia in the literature-all principally with catatonic stupor-with an average age of 56 years (range: 27-92) and balanced prevalence between sexes. Withdrawal catatonia tends to occur only after chronic use of alcohol or sedative-hypnotic agents with a typical onset of 3-7 days after discontinuation and duration of 3-10 days. Withdrawal catatonia is responsive to benzodiazepines or electroconvulsive therapy. Features that suggest a parallel between withdrawal catatonia and withdrawal delirium include time course, neurobiologic convergence, efficacy of benzodiazepines and electroconvulsive therapy, typical absence of abnormal electroencephalographic findings, and phenotypic classification suggested by a recent literature in sleep medicine. CONCLUSION Alcohol and sedative-hypnotic withdrawal may present with catatonia or catatonic features. The clinical and neurobiologic convergence between withdrawal catatonia and withdrawal delirium deserves further attention. In view of these similarities, we propose that withdrawal delirium may represent excited catatonia: these new viewpoints may serve as a substrate for a better understanding of the delirium-catatonia spectrum.

Catatonia vis-à-vis delirium: the significance of recognizing catatonia in altered mental status. Gen Hosp Psychiatry 2015; 37:554-9. [PMID: 26162545 DOI: 10.1016/j.genhosppsych.2015.06.011] [Citation(s) in RCA: 44] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2015] [Revised: 06/12/2015] [Accepted: 06/12/2015] [Indexed: 12/13/2022]
Abstract
BACKGROUND Catatonia is seldom considered in evaluation of altered mental status (AMS) in medical settings. Furthermore, catatonia often meets delirium criteria due to incoherence, altered awareness and behavioral change. Catatonia may co-occur with or be preferentially diagnosed as delirium. METHODS We conducted a systematic literature review of MEDLINE, EMBASE and PsycINFO on the relationship between catatonia and delirium. We also juxtapose clinical features of these syndromes and outline a structured approach to catatonia evaluation and management in acute medical settings. RESULTS These syndromes share tremendous overlap: the historical catatonia-related terms "delirious mania" and "delirious depression" bespeak of literal confusion differentiating them. Only recently has evidence on their relationship progressed beyond case series and reports. Neurological conditions account for the majority of medical catatonia cases. CONCLUSIONS New-onset catatonia warrants a medical workup, and catatonic features in AMS may guide clinicians to a neurological condition (e.g., encephalitis, seizures or structural central nervous system disease). Lorazepam or electroconvulsive therapy (ECT) should be considered even in medical catatonia, and neuroleptics should be used with caution. Moreover, ECT may prove lifesaving in malignant catatonia. Further studies on the relationship between delirium and catatonia are warranted.

Abstract
BACKGROUND Although insomnia is common among people with restless legs syndrome (RLS), its impact on the daily suffering of those with RLS remains unclear. This study aimed to compare the differential impact of clinical insomnia on depression and quality of life (QoL) among people with RLS, primary insomnia, and healthy controls. METHODS A total of 148 people with RLS, 115 with primary insomnia, and 117 healthy controls were enrolled into this cross-sectional study. Participants completed sleep, depression, and QoL questionnaires. Clinical insomnia was defined as Korean version of the Insomnia Severity Index (K-ISI) ≥ 15. Correlation coefficients between sleep measures and both depression and QoL were calculated. Multivariate regression was used to identify the clinical factors that were most closely associated with depression and QoL among people with RLS and primary insomnia. RESULTS Participants with RLS had insomnia and sleep quality at intermediate levels between the healthy controls and primary insomnia subjects, but those with clinical insomnia had equivalent depression and QoL scores regardless of RLS diagnosis. Insomnia severity correlated with depression and QoL in RLS and primary insomnia. Multivariate regression, however, revealed that RLS severity was the most overall predictive factor for depression and QoL among those with RLS. Insomnia severity was the strongest predictor in primary insomnia. CONCLUSION Insomnia was more closely associated with depression and QoL among people with primary insomnia than those with RLS, but clinical insomnia may have a significant impact in RLS as well. Future RLS studies should account for sleep quality in addition to RLS symptom severity when investigating mood and QoL.
