Abstract
Background: Delirium management is crucial in palliative care. Morphine effectively relieves dyspnea due to heart failure. However, the effect of morphine, which is used to relieve dyspnea due to heart failure, on the incidence of delirium has not been examined to date. Objective: To evaluate the effect of morphine, which is used to relieve dyspnea due to heart failure, on delirium. Design: Retrospective observational study. Setting/Subjects: Subjects were identified from Osaka University Hospital records, located in Japan, from January 1, 2010, to September 30, 2021. The case group consisted of admissions for heart failure or cardiomyopathy registered in electronic medical records. Morphine was administered to relieve dyspnea due to heart failure, and no surgeries or procedures were performed. The control group consisted of admissions for heart failure or cardiomyopathy in the Diagnosis Procedure Combination (DPC) database, which did not include administration of morphine, oxycodone, or fentanyl during the hospitalization period and patients did not undergo surgery or any other procedure. Measurements: The incidence of delirium was assessed. Results: The odds ratios for morphine in the multivariate logistic regression analysis with propensity score and univariate logistic regression analysis after propensity score matching were 1.406 (95% confidence interval (CI) [0.249-7.957]) and 1.034 (95% CI [0.902-1.185]), respectively. Conclusions: Morphine, which is used to relieve dyspnea due to heart failure, had minimal effect on the incidence of delirium. This information is likely to be beneficial for the future use of morphine in the management of dyspnea in patients with heart failure.

The Confusion Assessment Method Could Be More Accurate than the Memorial Delirium Assessment Scale for Diagnosing Delirium in Older Cancer Patients: An Exploratory Study. Curr Oncol 2023; 30:8245-8254. [PMID: 37754513 PMCID: PMC10529689 DOI: 10.3390/curroncol30090598] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Revised: 08/31/2023] [Accepted: 09/05/2023] [Indexed: 09/28/2023] Open
Abstract
BACKGROUND Older people with cancer carry a high risk of delirium, an underdiagnosed syndrome due to its diagnostic complexity and often subtle presentation. Tools based on the Diagnostic and Statistical Manual of Mental Disorders (DSM) are available to different health professionals. Our aim is to assess the prevalence of delirium in older people with cancer in an inpatient unit and the accuracy of the Confusion Assessment Method (CAM) and Memorial Delirium Assessment Scale (MDAS). METHODS This exploratory, cross-sectional study included people aged 65 years or older with a diagnosis of cancer and admitted to the medical oncology unit from June 2021 to December 2022. The diagnostic accuracy of CAM and MDAS was analyzed against the gold standard medical diagnosis based on DSM-5 criteria by two medical oncologists. The cutoff point for the MDAS was determined using a receiver-operating characteristics (ROC) curve. RESULTS Among the 75 included patients (mean age 71.6 years, standard deviation 4.1; 52% males), the prevalence of delirium was 62.7%. The most prevalent types of cancer in patients with delirium were hematological and lung cancer. The scale with the highest diagnostic accuracy was the CAM, with a sensitivity of 100% and specificity of 86%, followed by the MDAS, with a sensitivity of 88% and specificity of 30%. The presence of cognitive impairment hindered the detection of delirium. CONCLUSIONS The CAM scale was more accurate than the MDAS pre-existing cognitive impairment in our sample. Further studies are needed to analyze the diagnostic accuracy of delirium tools in older populations with cancer and in the presence of cognitive impairment.

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

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

Abstract
OBJECTIVE A web-based application was developed for medical staff to easily access and use a comprehensive delirium prevention management program-comprising risk prediction, assessment, and intervention-even in long-term care facilities with insufficient systems. DESIGN A randomized control trial. SETTING AND PARTICIPANTS A long-term care facility with 250 beds in Korea. Participants were 130 facility residents aged 18 or older who understood the purpose of this study and for whom a legal representative provided participation consent. Participants were randomly assigned to the intervention and control groups (n = 65 per group). METHODS The participants' risk of delirium episodes was predicted using the web-based application Web_DeliPREVENT_4LCF. Delirium was assessed using the built-in Short Confusion Assessment Method (S-CAM). Among the intervention group, nonpharmacological, multicomponent delirium prevention interventions guided by the application were applied to participants who were predicted to be at risk for delirium or tested positive for delirium. The intervention was provided for 30 days. RESULTS The intervention group had a 0.30 times lower incidence of delirium [95% confidence interval (CI) 0.12-0.79; P = .015] and 0.08 times lower 1-month hospitalization mortality (95% CI 0.01-0.79; P = .031) than the control group. There were no differences between the 2 groups in delirium severity, mortality, and 3-month hospitalization mortality, long-term care facility discharge, and length of stay. CONCLUSIONS AND IMPLICATIONS The Web_DeliPREVENT_4LCF was effective in reducing delirium episodes and 1-month in-hospital mortality. Therefore, even in Korean long-term care facilities, which lack manpower and electronic medical record systems compared with general hospitals, the health care professional can easily access and use the app for early detection and preventive intervention for residents' delirium.

Abstract
PURPOSE To systematically collect published research in order to identify and quantify risk factors for delirium in advanced cancer patients. METHODS The Cochrane Library, PubMed, Proquest, CINAHL, Web of Science, Ovid MEDLINE, Embase, Scopus, Chinese Wanfang Data, Chinese Periodical Full-text Database (VIP), Chinese Biomedical Literature Database (CBM), and Chinese National Knowledge Infrastructure (CNKI) were systematically searched for cohort or case-control studies reporting individual risk factors for delirium among advanced-stage cancer patients published prior to March 2022. The Newcastle-Ottawa Scale was used to assess the methodological quality of included studies. The pooled adjusted odds ratio (aOR) and its 95% confidence interval were calculated using the RevMan 5.4 software package. RESULTS A total of 15 studies with data from 3106 advanced cancer patients were included in our analysis. Nine studies were high-quality and six were of moderate quality. Pooled analyses revealed that 11 risk factors were statistically significant. High-intensity risk factors included sleep disturbance, infection, cachexia and the Palliative Prognostic Index; medium-intensity risk factors included male sex, renal failure, dehydration and drowsiness; low-intensity risk factors included age, total bilirubin and opioid use. Antibiotic use was found to have been a protective factor. CONCLUSIONS We identified 12 independent risk factors that were significantly associated with delirium in advanced cancer patients and provide an evidence-based foundation to implement appropriate preventive strategies.

Abstract
PURPOSE: Acute palliative care units (APCUs) are inpatient services in tertiary hospitals that provide intensive symptom management and assist in hospital discharge for transitions to hospice care. We aimed to analyze the clinical outcomes of operating an APCU at a comprehensive cancer center. PATIENTS AND METHODS: We retrospectively reviewed the medical records of 1,440 consecutive patients admitted to the APCU and analyzed demographic and clinical information, discharge outcomes, symptom assessments using the Edmonton Symptom Assessment System, spiritual distress, and financial distress. RESULTS: The median age of patients was 67.0 (range, 23-97) years, and 41% were female. The most common primary cancer types were lung (21.9%), hepatopancreatobiliary (14.1%), and colorectal cancers (12.9%). The median length of stay was 8.0 days (range, 1-60 days), and 31.0% of patients died in the APCU. Death in the APCU showed a significant decrease over time, and overall inpatient death in oncology wards did not increase after APCU opening. In total, 44.7% of patients were discharged to government-certified hospice centers. The proportion of patients discharged to certified hospice centers increased from 32.2% in 2015 to 62.4% in 2018. Among 715 patients with a follow-up evaluation 1 week after admission, Edmonton Symptom Assessment System symptom scores, spiritual distress, and financial distress showed statistically significant improvements compared with the baseline symptom scores ( P < .001). This improvement was limited to patients who did not die in the APCU. CONCLUSION: Patients with advanced cancer admitted to the APCU may experience significant improvements in distressing symptoms. The majority of patients requiring transition to hospice were successfully transferred to certified hospice centers. The percentage discharged alive improved over time.

Abstract
BACKGROUND Delirium is common and distressing for patients receiving palliative care. Interventions targetting modifiable risk factors in other settings have been shown to prevent delirium. Research on delirium risk factors in palliative care can inform context-specific risk-reduction interventions. AIM To investigate risk factors for the development of delirium in adult patients receiving specialist palliative care. DESIGN Systematic review and meta-analysis (PROSPERO CRD42019157168). DATA SOURCES CINAHL, Cochrane Database of Systematic Reviews, Embase, MEDLINE and PsycINFO (1980-2021) were searched for studies reporting the association of risk factors with delirium incidence/prevalence for patients receiving specialist palliative care. Study risk of bias and certainty of evidence for each risk factor were assessed. RESULTS Of 28 included studies, 16 conducted only univariate analysis, 12 conducted multivariate analysis. The evidence for delirium risk factors was limited with low to very low certainty. POTENTIALLY MODIFIABLE RISK FACTORS Opioids and lower performance status were positively associated with delirium, with some evidence also for dehydration, hypoxaemia, sleep disturbance, liver dysfunction and infection. Mixed, or very limited, evidence was found for some factors targetted in multicomponent prevention interventions: sensory impairments, mobility, catheter use, polypharmacy (single study), pain, constipation, nutrition (mixed evidence). NON-MODIFIABLE RISK FACTORS Older age, male sex, primary brain cancer or brain metastases and lung cancer were positively associated with delirium. CONCLUSIONS Findings may usefully inform interventions to reduce delirium risk but more high quality prospective cohort studies are required to enable greater certainty about associations of different risk factors with delirium during specialist palliative care.

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

Abstract
Objective: Delirium is common and highly distressing for the palliative care population. Until now, no study has systematically reviewed the risk factors of delirium in the palliative care population. Therefore, we performed a systematic review and meta-analysis to evaluate delirium risk factors among individuals receiving palliative care. Methods: We systematically searched PubMed, Medline, Embase, and Cochrane database to identify relevant observational studies from database inception to June 2021. The methodological quality of the eligible studies was assessed by the Newcastle Ottawa Scale. We estimated the pooled adjusted odds ratio (aOR) for individual risk factors using the inverse variance method. Results: Nine studies were included in the review (five prospective cohort studies, three retrospective case-control studies and one retrospective cross-section study). In pooled analyses, older age (aOR: 1.02, 95% CI: 1.01-1.04, I 2 = 37%), male sex (aOR:1.80, 95% CI: 1.37-2.36, I 2 = 7%), hypoxia (aOR: 0.87, 95% CI: 0.77-0.99, I 2 = 0%), dehydration (aOR: 3.22, 95%CI: 1.75-5.94, I 2 = 18%), cachexia (aOR:3.40, 95% CI: 1.69-6.85, I 2 = 0%), opioid use (aOR: 2.49, 95%CI: 1.39-4.44, I 2 = 0%), anticholinergic burden (aOR: 1.18, 95% CI: 1.07-1.30, I 2 = 9%) and Eastern Cooperative Oncology Group Performance Status (aOR: 2.54, 95% CI: 1.56-4.14, I 2 = 21%) were statistically significantly associated with delirium. Conclusion: The risk factors identified in our review can help to highlight the palliative care population at high risk of delirium. Appropriate strategies should be implemented to prevent delirium and improve the quality of palliative care services.

Abstract
BACKGROUND Delirium is a common and distressing neurocognitive condition that frequently affects patients in palliative care settings and is often underdiagnosed. AIM Expanding on a 2013 review, this systematic review examines the incidence and prevalence of delirium across all palliative care settings. DESIGN This systematic review and meta-analyses were prospectively registered with PROSPERO and included a risk of bias assessment. DATA SOURCES Five electronic databases were examined for primary research studies published between 1980 and 2018. Studies on adult, non-intensive care and non-postoperative populations, either receiving or eligible to receive palliative care, underwent dual reviewer screening and data extraction. Studies using standardized delirium diagnostic criteria or valid assessment tools were included. RESULTS Following initial screening of 2596 records, and full-text screening of 153 papers, 42 studies were included. Patient populations diagnosed with predominantly cancer (n = 34) and mixed diagnoses (n = 8) were represented. Delirium point prevalence estimates were 4%-12% in the community, 9%-57% across hospital palliative care consultative services, and 6%-74% in inpatient palliative care units. The prevalence of delirium prior to death across all palliative care settings (n = 8) was 42%-88%. Pooled point prevalence on admission to inpatient palliative care units was 35% (confidence interval = 0.29-0.40, n = 14). Only one study had an overall low risk of bias. Varying delirium screening and diagnostic practices were used. CONCLUSION Delirium is prevalent across all palliative care settings, with one-third of patients delirious at the time of admission to inpatient palliative care. Study heterogeneity limits meta-analyses and highlights the future need for rigorous studies.
