Abstract
BACKGROUND Delirium is a common yet challenging condition in older hospitalized patients, associated with various adverse outcomes. Environmental factors, such as room changes, may contribute to the development or severity of delirium. Most previous research has focused on preventing and reducing this condition by addressing risk factors and facilitating reorientation during hospital stay. OBJECTIVE We aimed to systematically develop a complex intervention to prevent delirium in older hospitalized patients by optimizing discharge and transfer processes and involving caregivers during and after these procedures. The intervention combines stakeholder and expert opinions, evidence, and theory. This article provides guidance and inspiration to research groups in developing complex interventions according to the recommendations in the Medical Research Council framework for complex interventions. DESIGN AND METHODS A stepwise multi-method study was conducted. The preparation phase included analysis of the context and current practice via focus groups. Based on these results, an expert workshop was organized, followed by a Delphi survey. Finally, the intervention was modeled and a program theory was developed, including a logic model. RESULTS A complex intervention was developed in an iterative process, involving healthcare professionals, delirium experts, researchers, as well as caregiver and patient representatives. The key intervention component is an 8-point-program, which provides caregivers with recommendations for preventing delirium during the transition phase and in the post-discharge period. Information materials (flyers, handbook, videos, posters, defined "Dos and Don'ts", discharge checklist), training for healthcare professionals, and status analyses are used as implementation strategies. In addition, roles were established for gatekeepers to act as leaders, and champions to serve as knowledge multipliers and trainers for the multi-professional team in the hospitals. CONCLUSIONS This study serves as an example of how to develop a complex intervention. In an additional step, the intervention and implementation strategies will be investigated for feasibility and acceptability in a pilot study with an accompanying process evaluation. TWEETABLE ABSTRACT Delirium prevention can benefit from optimizing discharge and transfer processes and involving caregivers of older patients in these procedures.

Abstract
OBJECTIVE To describe pharmacological and non-pharmacological practices for delirium, carried out by psychiatry residents and psychiatrists in Colombia. METHODS An anonymous survey was conducted based on the consensus of experts of the Liaison Psychiatry Committee of the Asociación Colombiana de Psiquiatría [Colombian Psychiatric Association] and on the literature review. It was sent by email to the association members. RESULTS 101 clinicians participated. Non-pharmacological preventive measures such as psychoeducation, correction of sensory problems or sleep hygiene are performed by 70% or more. Only about 1 in 10 participants are part of an institutional multi-component prevention programme. The preventive prescription of drugs was less than 20%. Regarding non-pharmacological treatment, more than 75% recommend correction of sensory difficulties, control of stimuli and reorientation. None of the participants indicated that the care at their centres is organised to enhance non-pharmacological treatment. 17.8% do not use medication in the treatment of delirium. Those who use it prefer haloperidol or quetiapine, particularly in hyperactive or mixed motor subtypes. CONCLUSIONS The practices of the respondents coincide with those of other experts around the world. In general, non-pharmacological actions are individual initiatives, which demonstrates the need in Colombian health institutions to commit to addressing delirium, in particular when its prevalence and consequences are indicators of quality of care.

Abstract
OBJECTIVES Persistent delirium is associated with poor outcomes in older adults but little is known about how to support longer-term recovery from delirium. The aim of this review was to identify and synthesise literature to understand mechanisms of recovery from delirium as a basis for designing an intervention that enables more effective recovery. METHODS A systematic search of literature relevant to the research question was conducted in two phases. Phase one focused on studies evaluating the efficacy of interventions to support recovery from delirium, and stage two used a wider search strategy to identify other relevant literature including similar patient groups and wider methodologies. Synthesis of the literature followed realist principles. RESULTS Phase one identified four relevant studies and stage two identified a further forty-six studies. Three interdependent recovery domains and four recovery facilitators were identified. Recovery domains were 1) support for physical recovery through structured exercise programmes; 2) support for cognitive recovery through reality orientation and cognitive stimulation; 3) support for emotional recovery through talking with skilled helpers. Recovery facilitators were 1) involvement and support of carers; 2) tailoring intervention to individual needs, preferences and abilities; 3) interpersonal connectivity and continuity in relationships and; 4) facilitating positive expressions of self. CONCLUSIONS Multicomponent interventions with elements that address all recovery domains and facilitators may have the most promise. Future research should build on this review and explore patients', carers', and professionals' tacit theories about the persistence of delirium or recovery from delirium in order to inform an effective intervention.

Abstract
Background
Cognitive impairment is common in older people admitted to hospital, but previous research has focused on single conditions.
Objective
This project sits in phase 0/1 of the Medical Research Council Framework for the Development and Evaluation of Complex Interventions. It aims to develop an understanding of current health-care outcomes. This will be used in the future development of a multidomain intervention for people with confusion (dementia and cognitive impairment) in general hospitals. The research was conducted from January 2015 to June 2018 and used data from people admitted between 2012 and 2013.
Design
For the review of outcomes, the systematic review identified peer-reviewed quantitative epidemiology measuring prevalence and associations with outcomes. Screening for duplication and relevance was followed by full-text review, quality assessment and a narrative review (141 papers). A survey sought opinion on the key outcomes for people with dementia and/or confusion and their carers in the acute hospital (n = 78). For the analysis of outcomes including cost, the prospective cohort study was in a medical admissions unit in an acute hospital in one Scottish health board covering 10% of the Scottish population. The participants (n = 6724) were older people (aged ≥ 65 years) with or without a cognitive spectrum disorder who were admitted as medical emergencies between January 2012 and December 2013 and who underwent a structured nurse assessment. ‘Cognitive spectrum disorder’ was defined as any combination of delirium, known dementia or an Abbreviated Mental Test score of < 8 out of 10 points. The main outcome measures were living at home 30 days after discharge, mortality within 2 years of admission, length of stay, re-admission within 2 years of admission and cost.
Data sources
Scottish Morbidity Records 01 was linked to the Older Persons Routine Acute Assessment data set.
Results
In the systematic review, methodological heterogeneity, especially concerning diagnostic criteria, means that there is significant overlap in conditions of patients presenting to general hospitals with confusion. Patients and their families expect that patients are discharged in the same or a better condition than they were in on admission or, failing that, that they have a satisfactory experience of their admission. Cognitive spectrum disorders were present in more than one-third of patients aged ≥ 65 years, and in over half of those aged ≥ 85 years. Outcomes were worse in those patients with cognitive spectrum disorders than in those without: length of stay 25.0 vs. 11.8 days, 30-day mortality 13.6% vs. 9.0%, 1-year mortality 40.0% vs. 26.0%, 1-year mortality or re-admission 62.4% vs. 51.5%, respectively (all p < 0.01). There was relatively little difference by cognitive spectrum disorder type; for example, the presence of any cognitive spectrum disorder was associated with an increased mortality over the entire period of follow-up, but with different temporal patterns depending on the type of cognitive spectrum disorder. The cost of admission was higher for those with cognitive spectrum disorders, but the average daily cost was lower.
Limitations
A lack of diagnosis and/or standardisation of diagnosis for dementia and/or delirium was a limitation for the systematic review, the quantitative study and the economic study. The economic study was limited to in-hospital costs as data for social or informal care costs were unavailable. The survey was conducted online, limiting its reach to older carers and those people with cognitive spectrum disorders.
Conclusions
Cognitive spectrum disorders are common in older inpatients and are associated with considerably worse health-care outcomes, with significant overlap between individual cognitive spectrum disorders. This suggests the need for health-care systems to systematically identify and develop care pathways for older people with cognitive spectrum disorders, and avoid focusing on only condition-specific pathways.
Future work
Development and evaluation of a multidomain intervention for the management of patients with cognitive spectrum disorders in hospital.

Abstract
Cancer occurs most frequently in patients aged 65 and older. With the increasing age of the world's population, there will be a significant increase in cancer diagnoses in older adults. Aging imposes a wide variety of physiological responses, comorbidities, and ailments, but older patients are less represented in clinical studies. Specific needs of older patients with cancer often go under-recognized and consequently unmet. In this review, common diagnoses that can affect the outcomes of this population, including frailty, malnutrition, and delirium, are discussed. Areas that need further research to improve the care of geriatric cancer patients, particularly in the hospital settings, are also identified.

Abstract
INTRODUCTION Although the majority of older patients admitted to a cardiology unit present with at least one geriatric syndrome, guidelines on managing heart disease often do not consider the complex needs of frail older patients. Geriatric co-management has demonstrated potential to improve functional status, and reduce complications and length of stay, but evidence on the effectiveness in cardiology patients is lacking. This study aims to determine if geriatric co-management is superior to usual care in preventing functional decline, complications, mortality, readmission rates, reducing length of stay and improving quality of life in older patients admitted for acute heart disease or for transcatheter aortic valve implantation, and to identify determinants of success for geriatric co-management in this population. METHODS AND ANALYSIS This prospective quasi-experimental before-and-after study will be performed on two cardiology units of the University Hospitals Leuven in Belgium in patients aged ≥75 years. In the precohort (n=227), usual care will be documented. A multitude of implementation strategies will be applied to allow for successful implementation of the model. Patients in the after cohort (n=227) will undergo a comprehensive geriatric assessment within 24 hours of admission to stratify them into one of three groups based on their baseline risk for developing functional decline: low-risk patients receive proactive consultation, high-risk patients will be co-managed by the geriatric nurse to prevent complications and patients with acute geriatric problems will receive an additional medication review and co-management by the geriatrician. ETHICS AND DISSEMINATION The study protocol was approved by the Medical Ethics Committee UZ Leuven/KU Leuven (S58296). Written voluntary (proxy-)informed consent will be obtained from all participants at the start of the study. Dissemination of results will be through articles in scientific and professional journals both in English and Dutch and by conference presentations. TRIAL REGISTRATION NUMBER NCT02890927.

Abstract
BACKGROUND Delirium, defined as an acute disorder of attention and cognition with high morbidity and mortality, can be prevented by multicomponent nonpharmacological interventions. The Hospital Elder Life Program (HELP) is the original evidence-based approach targeted to delirium risk factors, which has been widely disseminated. OBJECTIVE To summarize the current state of the evidence regarding HELP and to highlight its effectiveness and cost savings. METHODS Systematic review of Ovid MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials from 1999 to 2017, using a combination of controlled vocabulary and keyword terms. RESULTS Of the 44 final articles included, 14 were included in the meta-analysis for effectiveness and 30 were included for examining cost savings, adherence and adaptations, role of volunteers, successes and barriers, and issues in sustainability. The results for delirium incidence, falls, length of stay, and institutionalization were pooled for meta-analyses. Overall, 14 studies demonstrated significant reductions in delirium incidence (odds ratio [OR] 0.47, 95% confidence interval [CI] 0.37-0.59). The rate of falls was reduced by 42% among intervention patients in three comparative studies (OR 0.58, 95% CI 0.35-0.95). In nine studies on cost savings, the program saved $1600-$3800 (2018 U.S. dollars) per patient in hospital costs and over $16,000 (2018 U.S. dollars) per person-year in long-term care costs in the year following delirium. The systematic review revealed that programs were generally successful in adhering to or appropriately adapting HELP (n = 13 studies) and in finding the volunteer role to be valuable (n = 6 studies). Successes and barriers to implementation were examined in 6 studies, including ensuring effective clinician leadership, finding senior administrative champions, and shifting organizational culture. Sustainability factors were examined in 10 studies, including adapting to local circumstances, documenting positive impact and outcomes, and securing long-term funding. CONCLUSION The Hospital Elder Life Program is effective in reducing incidence of delirium and rate of falls, with a trend toward decreasing length of stay and preventing institutionalization. With ongoing efforts in continuous program improvement, implementation, adaptations, and sustainability, HELP has emerged as a reference standard model for improving the quality and effectiveness of hospital care for older persons worldwide.

Abstract
This chapter will provide an overview of the major neurologic complications of common cardiac and vascular surgeries, such as coronary artery bypass grafting and carotid endarterectomy. Neurologic complications after cardiac and vascular surgeries can cause significant morbidity and mortality, which can negate the beneficial effects of the intervention. Some of the complications to be discussed include ischemic and hemorrhagic stroke, seizures, delirium, cognitive dysfunction, cerebral hyperperfusion syndrome, cranial nerve injuries, and peripheral neuropathies. The severity of these complications can range from mild to lethal. The etiology of complications can include a variety of mechanisms, which can differ based on the type of cardiac or vascular surgery that is performed. Our knowledge about neuropathology, prevention, and management of surgical complications is growing and will be discussed in this chapter. It is imperative for clinicians to be familiar with these complications in order to narrow the differential diagnosis, start early management, anticipate the natural history, and improve outcomes.

Abstract
BACKGROUND Delirium is a common mental disorder, which is distressing and has serious adverse outcomes in hospitalised patients. Prevention of delirium is desirable from the perspective of patients and carers, and healthcare providers. It is currently unclear, however, whether interventions for preventing delirium are effective. OBJECTIVES To assess the effectiveness of interventions for preventing delirium in hospitalised non-Intensive Care Unit (ICU) patients. SEARCH METHODS We searched ALOIS - the Cochrane Dementia and Cognitive Improvement Group's Specialized Register on 4 December 2015 for all randomised studies on preventing delirium. We also searched MEDLINE (Ovid SP), EMBASE (Ovid SP), PsycINFO (Ovid SP), Central (The Cochrane Library), CINAHL (EBSCOhost), LILACS (BIREME), Web of Science core collection (ISI Web of Science), ClinicalTrials.gov and the WHO meta register of trials, ICTRP. SELECTION CRITERIA We included randomised controlled trials (RCTs) of single and multi- component non-pharmacological and pharmacological interventions for preventing delirium in hospitalised non-ICU patients. DATA COLLECTION AND ANALYSIS Two review authors examined titles and abstracts of citations identified by the search for eligibility and extracted data independently, with any disagreements settled by consensus. The primary outcome was incidence of delirium; secondary outcomes included duration and severity of delirium, institutional care at discharge, quality of life and healthcare costs. We used risk ratios (RRs) as measures of treatment effect for dichotomous outcomes; and between group mean differences and standard deviations for continuous outcomes. MAIN RESULTS We included 39 trials that recruited 16,082 participants, assessing 22 different interventions or comparisons. Fourteen trials were placebo-controlled, 15 evaluated a delirium prevention intervention against usual care, and 10 compared two different interventions. Thirty-two studies were conducted in patients undergoing surgery, the majority in orthopaedic settings. Seven studies were conducted in general medical or geriatric medicine settings.We found multi-component interventions reduced the incidence of delirium compared to usual care (RR 0.69, 95% CI 0.59 to 0.81; seven studies; 1950 participants; moderate-quality evidence). Effect sizes were similar in medical (RR 0.63, 95% CI 0.43 to 0.92; four studies; 1365 participants) and surgical settings (RR 0.71, 95% CI 0.59 to 0.85; three studies; 585 participants). In the subgroup of patients with pre-existing dementia, the effect of multi-component interventions remains uncertain (RR 0.90, 95% CI 0.59 to 1.36; one study, 50 participants; low-quality evidence).There is no clear evidence that cholinesterase inhibitors are effective in preventing delirium compared to placebo (RR 0.68, 95% CI, 0.17 to 2.62; two studies, 113 participants; very low-quality evidence).Three trials provide no clear evidence of an effect of antipsychotic medications as a group on the incidence of delirium (RR 0.73, 95% CI, 0.33 to 1.59; 916 participants; very low-quality evidence). In a pre-planned subgroup analysis there was no evidence for effectiveness of a typical antipsychotic (haloperidol) (RR 1.05, 95% CI 0.69 to 1.60; two studies; 516 participants, low-quality evidence). However, delirium incidence was lower (RR 0.36, 95% CI 0.24 to 0.52; one study; 400 participants, moderate-quality evidence) for patients treated with an atypical antipsychotic (olanzapine) compared to placebo (moderate-quality evidence).There is no clear evidence that melatonin or melatonin agonists reduce delirium incidence compared to placebo (RR 0.41, 95% CI 0.09 to 1.89; three studies, 529 participants; low-quality evidence).There is moderate-quality evidence that Bispectral Index (BIS)-guided anaesthesia reduces the incidence of delirium compared to BIS-blinded anaesthesia or clinical judgement (RR 0.71, 95% CI 0.60 to 0.85; two studies; 2057 participants).It is not possible to generate robust evidence statements for a range of additional pharmacological and anaesthetic interventions due to small numbers of trials, of variable methodological quality. AUTHORS' CONCLUSIONS There is strong evidence supporting multi-component interventions to prevent delirium in hospitalised patients. There is no clear evidence that cholinesterase inhibitors, antipsychotic medication or melatonin reduce the incidence of delirium. Using the Bispectral Index to monitor and control depth of anaesthesia reduces the incidence of postoperative delirium. The role of drugs and other anaesthetic techniques to prevent delirium remains uncertain.

Abstract
Background The aim of this study was to evaluate the long term effects after discharge of a hospital-based geriatric liaison intervention to prevent postoperative delirium in frail elderly cancer patients treated with an elective surgical procedure for a solid tumour. In addition, the effect of a postoperative delirium on long term outcomes was examined. Methods A three month follow-up was performed in participants of the Liaison Intervention in Frail Elderly study, a multicentre, prospective, randomized, controlled trial. Patients were randomized to standard treatment or a geriatric liaison intervention. The intervention consisted of a preoperative geriatric consultation, an individual treatment plan targeted at risk factors for delirium and daily visits by a geriatric nurse during the hospital stay. The long term outcomes included: mortality, rehospitalisation, Activities of Daily Living (ADL) functioning, return to the independent pre-operative living situation, use of supportive care, cognitive functioning and health related quality of life. Results Data of 260 patients (intervention n = 127, Control n = 133) were analysed. There were no differences between the intervention group and usual-care group for any of the outcomes three months after discharge. The presence of postoperative delirium was associated with: an increased risk of decline in ADL functioning (OR: 2.65, 95% CI: 1.02–6.88), an increased use of supportive assistance (OR: 2.45, 95% CI: 1.02–5.87) and a decreased chance to return to the independent preoperative living situation (OR: 0.18, 95% CI: 0.07–0.49). Conclusions A hospital-based geriatric liaison intervention for the prevention of postoperative delirium in frail elderly cancer patients undergoing elective surgery for a solid tumour did not improve outcomes 3 months after discharge from hospital. The negative effect of a postoperative delirium on late outcome was confirmed. Trial Registration Nederlands Trial Register, Trial ID NTR 823.

Abstract
Multicomponent delirium prevention strategies have been shown in intervention studies consistently to reduce the occurrence of delirium. Based on this convincing evidence base, the National Institute for Health and Care Excellence has advocated the widespread adoption of multicomponent delirium prevention interventions into the routine inpatient care of older people. However, despite successful reductions in incident delirium of about a third, anticipated reductions in mortality or admissions to long-term care--both clinically important endpoints statistically correlated with the occurrence of delirium--have not been conclusively observed. We hypothesise that the reasons for this disconnection are partly methodological, due to difficulties in delirium detection and blinding of study personnel to the intervention, but predominantly due to the underlying relationship between delirium and the abnormal health state of frailty; the interaction between these two geriatric syndromes is currently poorly understood.

Abstract
BACKGROUND A decreased incidence of delirium following the application of non-pharmacologic intervention protocols to several patient populations has been previously reported. However, few studies have been conducted to examine the effects of their application to intensive care unit (ICU) patients. OBJECTIVES To examine the effects of applying a tailored delirium preventive protocol, developed by the authors, to ICU patients by analyzing its effects on delirium incidence, in-hospital mortality, ICU readmission, and length of ICU stay in a Korean hospital. DESIGN A single-blind randomized controlled trial. SETTINGS A 1049-bed general hospital with a 105-bed ICU. PARTICIPANTS Sixty and 63 ICU patients were randomly assigned to the intervention and control groups, respectively. METHODS The researchers applied the delirium prevention protocol to the intervention group every day for the first 7 days of ICU hospitalization. Delirium incidence, mortality, and re-admission to the ICU during the same hospitalization period were analyzed by logistic regression analysis; the 7- and 30-day in-hospital mortality by Kaplan-Meier survival and Cox proportional hazard regression analysis; and length of ICU stay was assessed by linear regression analysis. RESULTS Application of the protocol had no significant effect on delirium incidence, in-hospital mortality, re-admission to the ICU, or length of ICU stay. Whereas the risk of 30-day in-hospital mortality was not significantly lower in the intervention than in the control group (OR: 0.33; 95% CI: 0.10-1.09), we found a significantly decreased 7-day in-hospital mortality in the intervention group after protocol application (HR: 0.09; 95% CI: 0.01-0.72). CONCLUSIONS Application of a tailored delirium prevention protocol to acute stage patients during the first 7 days of ICU hospitalization appeared to reduce the 7-day in-hospital risk of mortality only for this patient population.

Abstract
IMPORTANCE Delirium, an acute disorder with high morbidity and mortality, is often preventable through multicomponent nonpharmacological strategies. The efficacy of these strategies for preventing subsequent adverse outcomes has been limited to small studies to date. OBJECTIVE To evaluate available evidence on multicomponent nonpharmacological delirium interventions in reducing incident delirium and preventing poor outcomes associated with delirium. DATA SOURCES PubMed, Google Scholar, ScienceDirect, and the Cochrane Database of Systematic Reviews from January 1, 1999, to December 31, 2013. STUDY SELECTION Studies examining the following outcomes were included: delirium incidence, falls, length of stay, rate of discharge to a long-term care institution (institutionalization), and change in functional or cognitive status. DATA EXTRACTION AND SYNTHESIS Two experienced physician reviewers independently and blindly abstracted data on outcome measures using a standardized approach. The reviewers conducted quality ratings based on the Cochrane risk-of-bias criteria for each study. MAIN OUTCOMES AND MEASURES We identified 14 interventional studies. The results for outcomes of delirium incidence, falls, length of stay, and institutionalization were pooled for the meta-analysis, but heterogeneity limited our meta-analysis of the results for change in functional or cognitive status. Overall, 11 studies demonstrated significant reductions in delirium incidence (odds ratio [OR], 0.47; 95% CI, 0.38-0.58). Four randomized or matched trials reduced delirium incidence by 44% (OR, 0.56; 95% CI, 0.42-0.76). The rate of falls decreased significantly among intervention patients in 4 studies (OR, 0.38; 95% CI, 0.25-0.60); in 2 randomized or matched trials, the rate of falls was reduced by 64% (OR, 0.36; 95% CI, 0.22-0.61). Length of stay and institutionalization also trended toward decreases in the intervention groups, with a mean difference of -0.16 (95% CI, -0.97 to 0.64) day shorter and the odds of institutionalization 5% lower (OR, 0.95; 95% CI, 0.71-1.26). Among higher-quality randomized or matched trials, length of stay trended -0.33 (95% CI, -1.38 to 0.72) day shorter, and the odds of institutionalization trended 6% lower (OR, 0.94; 95% CI, 0.69-1.30). CONCLUSIONS AND RELEVANCE Multicomponent nonpharmacological delirium prevention interventions are effective in reducing delirium incidence and preventing falls, with a trend toward decreasing length of stay and avoiding institutionalization. Given the current focus on prevention of hospital-based complications and improved cost-effectiveness of care, this meta-analysis supports the use of these interventions to advance acute care for older persons.

Abstract
Dementia is an illness that progressively affects cognition, emotion, and functional status. It can be complicated by delirium, an acute disturbance of consciousness and cognition that develops over a short course with fluctuating symptoms. Patients with dementia who experience delirium tend to have slower resolution of symptoms, more adverse events, and poorer outcomes. There are significant health care expenditures associated with delirium. Many health care providers fail to recognize and diagnose delirium. The confusion assessment method is a suggested tool for diagnosing delirium. Delirium is multifactorial, occurring in an individual who has a predisposing factor (dementia is the number 1 risk factor) and is exposed to further precipitating risk factors that are often preventable. The main focus of treatment and management of delirium should be on prevention, which can be achieved through assessing patients for predisposing and precipitating factors. If a patient does develop delirium, a reassessment of precipitating factors is the first step in treatment, and then nonpharmacologic or pharmacologic treatment can be considered. The use of antipsychotics or melatonin to treat delirium in dementia is considered off-label.

Abstract
AIMS The aim of this study was to evaluate the effect of a delirium prevention strategy. BACKGROUND A high prevalence has been reported for delirium after liver transplantation surgery in the intensive care unit (ICU). Delirium increases treatment costs because of treatment delays, prolonged hospital stays and other associated complications. Despite all those problems associated with delirium, a systemic prevention strategy does not exist yet. DESIGN This study used an economic evaluation design by reviewing relevant medical records. METHODS Study objects were 130 patients who were admitted to the ICU after liver transplantation surgery. After looking at the medical records of these patients, we divided them into two groups according to the application of the prevention strategy. This study analysed the costs and benefits of the prevention strategy between the groups. RESULTS The prevalence rate of delirium was 35·3% in the prevention-care group and 51·6% in the usual-care group. A sum of $38·4 was invested for the prevention strategy in opposite to the expected total costs of $5578 for a probable treatment. Thus, the net benefit was $5539·6 with a benefit ratio of 145·3 CONCLUSIONS: A strategy is necessary for the delirium prevention of patients in the ICU to decrease the economic burden. RELEVANCE TO CLINICAL PRACTICE This study demonstrated that a prevention strategy was cost-effective because of its low input costs. With low additional investment, it is expected that this prevention strategy will be more available to other patients in the future.

Abstract
BACKGROUND Delirium is associated with substantial morbidity and mortality rates in elderly hospitalised patients, and a growing problem due to increase in life expectancy. Implementation of standardised non-pharmacological delirium prevention strategies is challenging and adherence remains low. Pharmacological delirium prevention with haloperidol, currently the drug of choice for delirium, seems promising. However, the generalisability of randomised controlled trial results is questionable since studies have only been performed in selected postoperative hip-surgery and intensive care unit patient populations. We therefore present the design of the multicenter, randomised, double-blind, placebo-controlled clinical trial on early pharmacological intervention to prevent delirium: haloperidol prophylaxis in older emergency department patients (The HARPOON study). METHODS/DESIGN In six Dutch hospitals, at-risk patients aged 70 years or older acutely admitted through the emergency department for general medicine and surgical specialties are randomised (n = 390) for treatment with prophylactic haloperidol 1 mg or placebo twice daily for a maximum of seven consecutive days. Primary outcome measure is the incidence of in-hospital delirium within seven days of start of the study intervention, diagnosed with the Confusion Assessment Method, and the Diagnostic and Statistical Manual of Mental Disorders, fourth edition criteria for delirium. Secondary outcome measures include delirium severity and duration assessed with the Delirium Rating Scale Revised 98; number of delirium-free days; adverse events; hospital length-of-stay; all-cause mortality; new institutionalisation; (Instrumental) Activities of Daily Living assessed with the Katz Index of ADL, and Lawton IADL scale; cognitive function assessed with the Six-item Cognitive Impairment Test, and the Dutch short form Informant Questionnaire on Cognitive Decline in the Elderly. Patients will be contacted by telephone three and six months post-discharge to collect data on cognitive- and physical function, home residency, all-cause hospital admissions, and all-cause mortality. DISCUSSION The HARPOON study will provide relevant information on the efficacy and safety of prophylactic haloperidol treatment for in-hospital delirium and its effects on relevant clinical outcomes in elderly at-risk medical and surgical patients.

Abstract
Delirium is a complex neuropsychiatric syndrome that impacts adversely upon patient outcomes and healthcare outcomes. Delirium occurs in approximately one in five hospitalised patients and is especially common in the elderly and patients who are highly morbid and/or have pre-existing cognitive impairment. However, efforts to improve management of delirium are hindered by gaps in our knowledge and issues that reflect a disparity between existing knowledge and real-world practice. This review focuses on evidence that can assist in prevention, earlier detection and more timely and effective pharmacological and non-pharmacological management of emergent cases and their aftermath. It points towards a new approach to delirium care, encompassing laboratory and clinical aspects and health services realignment supported by health managers prioritising delirium on the healthcare change agenda. Key areas for future research and service organisation are outlined in a plan for improved delirium care across the range of healthcare settings and patient populations in which it occurs.

Abstract
Because of the cost of nursing home care and desire of older adults to stay in their homes, it is important for health care providers to understand the factors that place older adults at risk for nursing home placement. This integrative review of 12 years of research, as published in 148 articles, explores the risk factors for nursing home placement of older adults. Using the framework of the vulnerable populations conceptual model developed by Flaskerud and Winslow (1998), we explored factors related to resource availability, relative risks, and health status. Important factors include socioeconomic status, having a caregiver, the availability and use of home- and community-based support services, race, acute illness particularly if hospitalization is required, medications, dementia, multiple chronic conditions, functional disability, and falls. Few intervention studies were identified. Development of evidence-based interventions and creation of policies to address modifiable risk factors are important next steps.

Abstract
BACKGROUND The purpose of this study was to examine whether a multidisciplinary intervention targeting drug-related problems, cognitive impairment, and discharge miscommunication could reduce readmissions in a general hospital population. METHODS This prospective, non-randomized intervention study was carried out at the department of general internal medicine at a tertiary university hospital. Two hundred medical inpatients living in the community and aged over 60 years were included. Ninety-nine patients received interventions and 101 received standard care. Control/intervention allocation was determined by geographic selection. Interventions consisted of a comprehensive medication review, improved discharge planning, post-discharge telephone follow-up, and liaison with the patient's general practitioner. The main outcome measures recorded were readmissions and hospital nights 12 months after discharge. Separate analyses were made for 12-month survivors and from an intention-to-treat perspective. Comparative analyses were made between groups as well as within groups over time. RESULTS After 12 months, survivors in the control group had 125 readmissions in total, compared with 58 in the intervention group (Mann-Whitney U test, P = 0.02). For hospital nights, the numbers were 1,228 and 492, respectively (P = 0.009). Yearly admissions had increased from the previous year in the control group from 77 to 125 (Wilcoxon signed-rank test, P = 0.002) and decreased from 75 to 58 in the intervention group (P = 0.25). From the intention-to-treat perspective, the same general pattern was observed but was not significant (1,827 versus 1,008 hospital nights, Mann-Whitney test, P = 0.054). CONCLUSION A multidisciplinary approach, targeting several different areas, could substantially lower readmissions and hospital costs in a non-terminal general hospital population.

Abstract
BACKGROUND Older people are commonly admitted to the acute hospital and increasing numbers will have dementia. In this study we systematically reviewed the prevalence, associations and outcomes of dementia in older people in the general hospital, to examine the range of diagnostic tools used and highlight gaps in the literature. METHODS We searched the English language literature using Embase, PsychInfo and Medline. Studies were included if they used validated criteria for diagnosing dementia, involved subjects over the age of 55 years and were set in the general hospital. RESULTS Fourteen papers were identified. Prevalence estimates for dementia in studies with robust methodology were 12.9-63.0%. Less than a third of studies screened for delirium or depression and therefore some subjects may have been misclassified as having dementia. The data were highly heterogeneous and prevalence estimates varied widely, influenced by study setting and demographic features of the cohorts. Patients with dementia in the acute hospital are older, require more hours of nursing care, have longer hospital stays, and are more at risk of delayed discharge and functional decline during admission. CONCLUSIONS When planning liaison services, the setting and demographic features of the population need to be taken into account. Most study cohorts were recruited from medical wards. More work is required on the prevalence of dementia in surgical and other specialties. A wider range of associations (particularly medical and psychiatric comorbidity) and outcomes should be studied so that care can be improved.

Abstract
Delirium is the leading complication of hospitalization for older adults. The role family caregivers could play in delirium prevention and how nurses could facilitate family participation has been largely unexplored. This study examined the feasibility of family participation in a multicomponent intervention program for delirium prevention in hospitalized older adults called Family-HELP, as an adaptation and extension of the Hospital Elder Life Program (HELP). Family-HELP demonstrates that active engagement of family caregivers in preventive interventions for delirium is feasible. Intervention completion occurred at least 55% of the time. Three themes emerged on barriers and facilitators for family participation: therapeutic relationships, partnership, and environment. Key to successful implementation of the program is attention to the identified barriers and facilitators. These findings have implications for clinicians committed to delivering quality inpatient care to older adults and their families, with the benefits of HELP being extended to include family caregivers with an important role in delirium prevention efforts.

Abstract
In the present healthcare environment, budget cuts, staff shortages, and resource limitations are grave concerns. The elderly in particular consume a considerable proportion of hospital resources. Thus, the discharge planner's role, particularly with respect to elderly patients, is extremely important. In this systematic review recent (within the last 10 years) randomized, controlled or quasi-experimental trials of discharge planning (DP) from hospital to home of patients age 65 years or older were examined. The most important finding was the paucity of investigations by social work professionals. A second important finding was the lack of appropriate reporting of methods and results. Where data were provided, an effect size was computed for statistically significant results (overall mean d = 0.51, SD 0.35). Large effects were noted for patient satisfaction, while moderate effects were evident for patients' quality of life and readmission rates. The integration and evaluation of current knowledge in this field may inform further research and may lead to the advancement of clinical practice and new policy development, with the ultimate goal of improving the quality of patient care and the quality of patient outcomes. The implications for social work clinicians and researchers are discussed.

Abstract
Dementia and delirium, the most common causes of cognitive impairment (CI) among hospitalized older adults, are associated with higher mortality rates, increased morbidity and higher health care costs. A growing body of science suggests that these older adults and their caregivers are particularly vulnerable to systems of care that either do not recognize or meet their needs. The consequences can be devastating for these older adults and add to the burden of hospital staff and caregivers, especially during the transition from hospital to home. Unfortunately, little evidence exists to guide optimal care of this patient group. Available research findings suggest that hospitalized cognitively impaired elders may benefit from interventions aimed at improving care management of both CI and co-morbid conditions but the exact nature and intensity of interventions needed are not known. This article will explore the need for improved transitional care for this vulnerable population and their caregivers.

Abstract
A robust set of quality measures is essential to provide consumers with a vehicleto evaluate nurses' contributions to the care of hospitalized patients, providers, and systems with a set of nursing processes and outcomes to guide quality improvement, and insurers with indicators to reward hospitals for high quality nursing services. The processes employed by the Nursing Care Performance Measures Steering Committee convened by the National Quality Forum (NQF) in 2004 resulted in the endorsement of 15 indicators of health care quality influenced by nurses and contributed to the identification of significant gaps in measurement and priority areas for future research. This critical review of the state of the science related to health care processes and outcomes that reflect nurses' contributions to the quality of care for hospitalized patients is intended to push the boundaries in the measurement of nursing performance. Specific recommendations for future research and measure development are presented.

Abstract
BACKGROUND Delirium is a common mental disorder with serious adverse outcomes in hospitalised patients. It is associated with increases in mortality, physical morbidity, length of hospital stay, institutionalisation and costs to healthcare providers. A range of risk factors has been implicated in its aetiology, including aspects of the routine care and environment in hospitals. Prevention of delirium is clearly desirable from patients' and carers' perspectives, and to reduce hospital costs. Yet it is currently unclear whether interventions for prevention of delirium are effective, whether they can be successfully delivered in all environments, and whether different interventions are necessary for different groups of patients. OBJECTIVES Our primary objective was to determine the effectiveness of interventions designed to prevent delirium in hospitalised patients. We also aimed to highlight the quality and quantity of research evidence to prevent delirium in these settings. SEARCH STRATEGY We searched the Specialized Register of the Cochrane Dementia and Cognitive Improvement Group on 28th September, 2005. As the searches in MEDLINE, EMBASE, CINAHL and PsycINFO for the Specialized Register would not necessarily have picked up all delirium prevention trials, these databases were searched again on 28th October, 2005. We also examined reference lists of retrieved articles, reviews and books. Experts in this field were contacted and the Internet searched for further references and to locate unpublished trials. SELECTION CRITERIA Randomised controlled trials evaluating any interventions to prevent delirium in hospitalised patients. DATA COLLECTION AND ANALYSIS Data collection and quality assessment were performed by three reviewers independently and agreement reached by consensus. MAIN RESULTS Six studies with a total of 833 participants were identified for inclusion. All were conducted in surgical settings, five in orthopaedic surgery and one in patients undergoing resection for gastric or colon cancer. Only one study of 126 hip fracture patients comparing proactive geriatric consultation with usual care was sufficiently powered to detect a difference in the primary outcome, incident delirium. Total cumulative delirium incidence during admission was reduced in the intervention group (OR 0.48 [95% CI 0.23, 0.98]; RR 0.64 [95% CI 0.37, 0.98]), suggesting a 'number needed to treat' of 5.6 patients to prevent one case. The intervention was particularly effective in preventing severe delirium. In logistic regression analyses adjusting for pre fracture dementia and Activities of Daily Living impairment, there was no reduction in effect size, OR 0.6, but this no longer remained significant [95% CI 0.3,1.3]. There was no effect on the duration of delirium episodes, length of hospital stay, and cognitive status or institutionalisation at discharge. There was also no significant difference in cumulative delirium incidence between treatment and control groups in a sub-group of 50 patients with dementia (RR 0.9 [95% CI 0.59, 1.36]). In another trial of low dose haloperidol prophylaxis, there was no difference in delirium incidence but the severity and duration of a delirium episode, and length of hospital stay were all reduced. We identified no completed studies in hospitalised medical, care of the elderly, general surgery, cancer or intensive care patients. In outcomes, no studies examined for death, use of psychotropic medication, activities of daily living, psychological morbidity, quality of life, carers or staff psychological morbidity, cost of intervention and cost to health care services. Outcomes were only reported up to discharge, with no studies reporting medium or longer-term effects. AUTHORS' CONCLUSIONS Research evidence on effectiveness of interventions to prevent delirium is sparse. Based on a single study, a programme of proactive geriatric consultation may reduce delirium incidence and severity in patients undergoing surgery for hip fracture. Prophylactic low dose haloperidol may reduce severity and duration of delirium episodes and shorten length of hospital admission in hip surgery. Further studies of delirium prevention are needed.

Abstract
Delirium is an under-recognized, highly prevalent form of organ dysfunction in the intensive care unit (ICU). It is imperative to be aware of risk factors for delirium in the ICU, some of which are modifiable. In the last 5 years, a new tool for detecting delirium among critically ill patients has been validated and found reliable for use at the bedside by psychiatrists and nonpsychiatrically trained personnel as well. The tool, the Confusion Assessment Method for the Intensive Care Unit, has enabled determination of the serious sequelae of delirium, including increased mortality, higher cost, longer length of hospital stay, failure of extubation, and burdensome, long-term cognitive impairment. This article reviews prevention and treatment options, and current pharmacologic and nonpharmacologic approaches to delirium, acknowledging limited but improving quality of evidence to date.

Abstract
BACKGROUND A high incidence of functional decline (deterioration in physical or cognitive function) during hospitalisation of older adults is reported. The role of exercise in preventing these deconditioning effects is unclear. OBJECTIVES To determine the effect of exercise interventions for acutely hospitalised older medical patients on functional status, adverse events and hospital outcomes. SEARCH STRATEGY We searched MEDLINE (1966-Feb 2006), CINAHL (1982-Feb 2006), EMBASE (1988 to Feb 2006), Cochrane Database of Systematic Reviews and Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 1, 2006), PEDro (1929- Feb 2006), Current Contents (1993- Feb 2006) and Sports Discus (1830-Feb 2006). The Journal of the American Geriatrics Society was hand searched. Additional studies were identified through reference and citation tracking, personal communications with a content expert and contacting authors of eligible trials. There was no language restriction. SELECTION CRITERIA Eligible studies were prospective randomised controlled trials (RCT) or prospective controlled clinical trials (CCT) comparing exercise for acutely hospitalised older medical patients to usual care or no treatment controls. DATA COLLECTION AND ANALYSIS Two independent reviewers extracted data relating to patient and hospital outcomes and assessed the method quality of included studies. Data were pooled in meta-analysis using the relative risk (RR) and absolute risk reduction (ARR) for dichotomous outcomes and the standardised mean difference (SMD) or the weighted mean difference (WMD) for continuous outcomes. MAIN RESULTS Of 3138 potentially relevant articles screened, 7 randomised controlled trials and 2 controlled clinical trials were included. The effect of exercise on functional outcome measures is unclear. No intervention effect was found on adverse events. Pooled analysis of multidisciplinary interventions that included exercise indicated a small significant increase in the proportion of patients discharged to home at hospital discharge (Relative Risk 1.08, 95% CI 1.03 to 1.14 and Numbers Needed to Treat 16, 95% CI 11 to 43) and a small but important reduction in acute hospital length of stay (weighted mean difference, -1.08 days, 95% CI -1.93 to -0.22) and total hospital costs (weighted mean difference, -US$278.65, 95% CI -491.85 to -65.44) compared to usual care. Pooled analysis of exercise intervention trials found no effect on the proportion of patients discharged to home or acute hospital length of stay. AUTHORS' CONCLUSIONS There is 'silver' level evidence (www.cochranemsk.org) that multidisciplinary intervention that includes exercise may increase the proportion of patients discharged to home and reduce length and cost of hospital stay for acutely hospitalised older medical patients.

Abstract
Critical care physicians often find themselves prognosticating for their patients, attempting to predict patient survival as well as disability. In the case of neurologic injury, this can be especially difficult. A frequent cause of coma in the intensive care unit is resuscitation following cardiac arrest, for which mortality and severe neurologic disability remain high. Recent studies of the clinical examination, of serum markers such as neuron-specific enolase, and of somatosensory evoked potentials allow accurate and specific prediction of which comatose patients are likely to suffer a poor outcome. Using these tools, practitioners can confidently educate the family for the majority of patients who will die or remain comatose at 1 month. Delirium is a less dramatic form of neurologic injury but, when sought, is strikingly prevalent. In addition, delirium in the intensive care unit is associated with increased mortality and poorer functional recovery, prompting investigation into preventative and therapeutic strategies to counter delirium. Finally, neurologic damage may persist long after the patient's recovery from critical illness, as is the case for cognitive dysfunction detected months and years after critical illness. Psychiatric impairment including depression or post-traumatic stress disorder may also arise. Mechanisms contributing to each of these entities are reviewed.

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

Abstract
PURPOSE OF REVIEW The management of sepsis and the multiple organ dysfunction syndrome has traditionally been centered on dysfunction of organs other than the brain (e.g., heart, lungs, or kidneys), although the brain is one of the most prevalent organs involved. Recent studies indicate that nonpulmonary acute organ dysfunction may contribute significantly to mortality and other important clinical outcomes. Acute confusional states (delirium) occur in 10 to 60% of the older hospitalized population and in 60 to 80% of patients in the intensive care unit, yet go unrecognized by the managing physicians and nurses in 32 to 66% of cases. Delirium is an important independent prognostic determinant of hospital outcomes, including duration of mechanical ventilation, nursing home placement, functional decline, and death. Recently, new monitoring instruments have been validated for monitoring of delirium in noncommunicative patients receiving mechanical ventilation. Hence, critical care physicians and nurses should routinely assess their patients for delirium and develop strategies for its prevention and treatment. RECENT FINDINGS This state-of-the-art review discusses in depth the delirium monitoring instruments, the pathophysiology and risk factors of delirium, its prognostic implications, and strategies (including ongoing clinical trials) to prevent and treat delirium. SUMMARY Delirium is extremely common and has significant prognostic implications in critically ill patients. Routine monitoring and a multimodal approach to prevent or reduce the prevalence of delirium are of paramount importance.

Abstract
AIM The aim of this systematic review was to determine the characteristics and efficacy of various multicomponent intervention strategies for delirium in hospitalized older people. BACKGROUND Delirium is a common accompaniment to acute illness in hospitalized older people and has greater costs of care concurrent as well as greater morbidity and mortality. METHODS A comprehensive search was undertaken involving all major databases (including the Cochrane Library, Medline, Cumulative Index for Nursing and Allied Health Literature and Invert) and reference lists of all relevant papers. Selection criteria were: evaluation of a multicomponent intervention for delirium, inclusion of an operational definition for delirium consistent with the Diagnostic and Statistical Manual of Mental Disorders-criteria, randomized controlled trials, studies with a quasi-experimental design and reporting on primary data. To generate a description of the characteristics of these multicomponent strategies, the components of these programmes were identified and categorized. Effects on incidence of delirium, cognitive functioning, duration and severity of delirium, functional status, hospital length of stay, and mortality were analysed. FINDINGS Three randomized controlled trials, three controlled studies and one before-after study were identified. Intervention strategies to prevent delirium proved to be the most efficacious in reducing its incidence, both with surgical and medical patients. Some additional positive effects of preventive strategies were found on the duration and severity of delirium, and functional status. Conversely, strategies to treat delirium were rather ineffective in older people admitted to medical services. In a population of older people admitted for surgery, however, a shorter duration and a diminished severity of delirium were demonstrated. None of intervention strategies produced beneficial effects on length of stay or mortality. CONCLUSION Multicomponent interventions to prevent delirium are the most effective and should be implemented through synergistic cooperation between the various healthcare disciplines. Nurses should play a pivotal role in prevention, early recognition and treatment.

Abstract
The prevalence of delirium in hospitalized patients aged 80 years or older ranges from 35 to 50%. Its onset is acute, recovery is erratic, and the principal differential diagnosis is dementia. Hypoactive confusion is a clinical form that should not be ignored. Prognosis is severe with impairments in activities of daily living and high mortality. Risk factors are age (older than 80 years), dementia, sensory impairments, dehydration, sleep deprivation and immobility. Initial treatment must focus on identifying the cause of the delirium. Primary nonpharmacological prevention in subjects at risk is possible and effective.

Abstract
Delirium poses a common and multifactorial complication in older patients with cancer. Delirium independently contributes to poorer clinical outcomes and impedes communication between patients with cancer, their family and health care providers. Because of its clinical impact and potential reversibility, efforts for prevention, early recognition or prompt treatment are critical. However, nurses and other health care providers often fail to recognize delirium or misattribute its symptoms to dementia, depression or old age. Yet, failure to determine an individual's risk for delirium can initiate the cascade of negative events causing additional distress for patients, family and health care providers alike. Therefore, parameters for determining an individual's risk for delirium and guidelines for the routine and systematic assessment of cognitive functioning are provided to form a basis for the prompt and accurate diagnosis of delirium. Guidelines for the prevention and treatment of delirium are also discussed.

Abstract
OBJECTIVES To determine whether costs of long-term nursing home (NH) care for patients who received a multicomponent targeted intervention (MTI) to prevent delirium while hospitalized were less than for those who did not receive the intervention. DESIGN Longitudinal follow-up from a randomized trial. SETTING Posthospital discharge settings: community-based care and NHs. PARTICIPANTS Eight hundred one hospitalized patients aged 70 and older. MEASUREMENTS Patients were followed for 1 year after discharge, and measures of NH service use and costs were constructed. Total long-term NH costs were estimated using a two-part regression model and compared across intervention and control groups. RESULTS Of the 400 patients in the intervention group and 401 patients in the matched control group, 153 (38%) and 148 (37%), respectively, were admitted to a NH during the year, and 54 (13%) and 51 (13%), respectively, were long-term NH patients. The MTI had no effect on the likelihood of receiving long-term NH care, but of patients receiving long-term NH care, those in the MTI group had significantly lower total costs, shorter length of stay and lower cost per survival day. Adjusted total costs were $50,881 per long-term NH patient in the MTI group and $60,327 in the control group, a savings of 15.7% (P=.01). CONCLUSION Active methods to prevent delirium are associated with a 15.7% decrease in long-term NH costs. Shorter length of stay of patients receiving long-term NH services was the primary source of these savings.

Abstract
OBJECTIVES To compare the Confusion Assessment Method (CAM) and CAM for the Intensive Care Unit (CAM-ICU) methods for detecting delirium in alert, nonintubated older ICU patients. DESIGN Comparison study. SETTING Fourteen-bed medical ICU of an 800-bed university teaching hospital. PARTICIPANTS Twenty-two patients aged 65 and older admitted to the ICU. MEASUREMENTS Two blinded, trained clinician-researchers who had undergone interrater reliability testing interviewed patients separately, usually within 10 minutes of each other (up to 120 minutes). Each researcher examined patients for the four key CAM criteria: acuteness, inattention, disorganized thinking, and altered level of consciousness. One researcher used the CAM method with the Mini-Mental State Examination and Digit Span; the other researcher used the CAM-ICU method with nonverbal cognitive and attention tasks. RESULTS Rates of delirium were 68% according to CAM and 50% according CAM-ICU. Comparing the two methods, agreement was 82%, with a kappa of 0.64. Using the CAM as the reference standard, the CAM-ICU had a sensitivity of 73% (95% confidence interval (CI)=60-86) and specificity of 100% (95% CI=56-100). There were four false-negative ratings using the CAM-ICU. Reasons for disparate results were that the CAM used more-detailed cognitive testing that detected more deficits (3 patients) and the time elapsed (90 minutes) between ratings in one patient with markedly fluctuating symptoms. CONCLUSION CAM and CAM-ICU agreement was moderately high. Although the CAM-ICU is recommended for ICU patients because of its brevity and ease of use, the standard CAM method may detect more subtle cases of delirium in nonintubated, verbal ICU patients.

Abstract
Urinary incontinence (UI) is a complex disorder affecting a large segment of the frail older population. Physical factors such as medication use and disease comorbidity can affect continence control. Cognitive disorders and functional decline pose additional challenges in management of urinary symptoms. Those individuals who have adequate socioeconomic support and caregiver assistance may have a greater advantage in maintaining continence.Physical, cognitive, functional, and psychosocial factors each contribute to the risk profile for both the development of frailty and the likelihood of experiencing UI.
