Effectiveness of antipsychotics for managing agitated delirium in patients with advanced cancer: a secondary analysis of a multicenter prospective observational study in Japan (Phase-R).

PURPOSE: Delirium is a common and serious comorbidity in patients with advanced cancer, necessitating effective management. Nonetheless, effective drugs for managing agitated delirium in patients with advanced cancer remain unclear in real-world settings. Thus, the present study aimed to explore an effective pharmacotherapy for this condition. METHODS: We conducted a secondary analysis of a multicenter prospective observational study in Japan. The analysis included patients with advanced cancer who presented with agitated delirium and received pharmacotherapy. Agitation was defined as a score of the Richmond Agitation-Sedation Scale for palliative care (RASS-PAL) of ≥ 1. The outcome was defined as -2 ≤ RASS-PAL ≤ 0 at 72 h after the initiation of pharmacotherapy. Multiple propensity scores were quantified using a multinomial logistic regression model, and adjusted odds ratios (ORs) were calculated for haloperidol, chlorpromazine, olanzapine, quetiapine, and risperidone. RESULTS: The analysis included 271 patients with agitated delirium, and 87 (32%) showed -2 ≤ RASS-PAL ≤ 0 on day 3. The propensity score-adjusted OR of olanzapine was statistically significant (OR, 2.91; 95% confidence interval, 1.12 to 7.80; P = 0.030). CONCLUSIONS: The findings suggest that olanzapine may effectively improve delirium agitation in patients with advanced cancer.

Optimizing smartphone psychotherapy for depressive symptoms in patients with cancer: Multiphase optimization strategy using a decentralized multicenter randomized clinical trial (J-SUPPORT 2001 Study).

AIM: Patients with cancer experience various forms of psychological distress, including depressive symptoms, which can impact quality of life, elevate morbidity risk, and increase medical costs. Psychotherapy and pharmacotherapy are effective for reducing depressive symptoms among patients with cancer, but most patients prefer psychotherapy. This study aimed to develop an efficient and effective smartphone psychotherapy component to address depressive symptom. METHODS: This was a decentralized, parallel-group, multicenter, open, individually randomized, fully factorial trial. Patients aged ≥20 years with cancer were randomized by the presence/absence of three cognitive-behavioral therapy (CBT) skills (behavioral activation [BA], assertiveness training [AT], and problem-solving [PS]) on a smartphone app. All participants received psychoeducation (PE). The primary outcome was change in the patient health questionnaire-9 (PHQ-9) total score between baseline and week 8. Secondary outcomes included anxiety. RESULTS: In total, 359 participants were randomized. Primary outcome data at week 8 were obtained for 355 participants (99%). The week 8 PHQ-9 total score was significantly reduced from baseline for all participants by -1.41 points (95% confidence interval [CI] -1.89, -0.92), but between-group differences in change scores were not significant (BA: -0.04, 95% CI -0.75, 0.67; AT: -0.16, 95% CI -0.87, 0.55; PS: -0.19, 95% CI -0.90, 0.52). CONCLUSION: As the presence of any of the three intervention components did not contribute to a significant additive reduction of depressive symptoms, we cannot make evidence-based recommendations regarding the use of specific smartphone psychotherapy.

A revision of JPOS/JASCC clinical guidelines for delirium in adult cancer patients: a summary of recommendation statements.

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.

Nationwide survey on family caregiver-perceived experiences of patients with cancer of unknown primary site.

PURPOSE: Cancer of unknown primary site (CUP) is an aggressive disease with poor prognosis. As research on the experiences of CUP patients and their families is scarce, this study aimed to compare the family caregiver-perceived burden of CUP with that of common cancers (lung, colon, and stomach cancers). The association between family caregiver-perceived burden and CUP patients' quality of life (QOL) at end-of-life and family depression, respectively, was also explored. METHODS: This was a pre-planned secondary analysis of nationwide cross-sectional survey data from the bereaved family caregivers of patients with cancer who died at 286 institutions. The major measurements were the eight-item family caregiver-perceived Burden scale (comprising specialist access, uncertainty, and prolonged diagnosis), Good Death Inventory, and Patient Health Questionnaire 9. RESULTS: Of 27,591 survey responses, we analyzed 97 and 717 responses from family caregivers of patients with CUP and common cancer, respectively. The families of CUP patients scored significantly higher on all three burden subscales than those of common cancer patients (effect sizes: specialist access subscale, 0.3; uncertainty subscale, 0.66; and prolonged diagnosis subscale, 0.69; adjusted P < 0.01). Greater family burden was significantly associated with lower patient QOL and higher family depression. Burden was significantly associated with being a spouse, second opinion consultation, and diagnosis period of > 1 month. CONCLUSION: The family caregivers of CUP patients experience poor specialist access, greater uncertainty, and a prolonged diagnosis. They should be cared for from the initial stages to establish access to specialists, obtain an early diagnosis, and reduce uncertainty.

Development and validation of the Terminal Delirium-Related Distress Scale to assess irreversible terminal delirium.

OBJECTIVE: There is no tool to appropriately assess terminal delirium, including the natural terminal course. The objective of this study was to develop an evaluation scale to assess distress from irreversible terminal delirium and to examine the validity of the scale. METHOD: Based on previous qualitative analysis and systematic literature searches, we carried out a survey regarding the views of bereaved families and developed a questionnaire. We extracted items that bereaved families regarded as important and constructed an evaluation scale of terminal delirium. Then, we applied the questionnaire in a cross-sectional questionnaire survey of bereaved relatives of cancer patients who were admitted to a hospice or a palliative care unit. RESULTS: We developed the Terminal Delirium-Related Distress Scale (TDDS), a 24 item questionnaire consisting of five subscales (support for families and respect for a patient, ability to communicate, hallucinations and delusions, adequate information about the treatment of delirium, and agitation and restlessness). Two hundred and eighty-one bereaved relatives participated in the validation phase. The construct validity was shown to be good by repeated factor analysis. Convergent validity, confirmed by the correlation between the TDDS and the Care Evaluation Scale (r = 0.651, P < 0.001), was also good. The TDDS had good internal consistency (Cronbach's alpha coefficient for all 24 items = 0.84). SIGNIFICANCE OF RESULTS: This study showed that the TDDS is a valid and feasible measure of irreversible terminal delirium.

Clinical features of dermatomyositis associated with anti-MDA5 antibodies by age.

OBJECTIVES: Anti-melanoma differentiation-associated gene 5 (MDA5) autoantibody-positive and age at onset ≥60 years are poor prognosis factors in polymyositis (PM) and dermatomyositis (DM) associated with interstitial lung disease (ILD) among Japanese patients. However, the influence of age on the clinical features of anti-MDA5 autoantibody-positive patients with DM remains unclear. METHODS: We retrospectively examined 40 patients with DM and anti-MDA5 autoantibodies according to age. We compared patients aged <60 and ≥60 years with respect to clinical features including laboratory test findings, high-resolution lung computed tomography data, treatment content, and complications such as infections and prognosis. We also examined clinical features between surviving and deceased patients in the older patient group. RESULTS: Of 40 enrolled patients, 13 were classified as old and 27 as young. Older patients had significantly fewer clinical symptoms including arthralgia/arthritis (p < .01), skin ulceration (p = .02), and higher mortality than younger patients (p = .02) complicated with rapidly progressive ILD (RP-ILD), combination immunosuppressive therapy, and strictly controlled infections. CONCLUSION: Clinical features and mortality of anti-MDA5 autoantibody-positive DM patients were influenced by age. Patients aged ≥60 years had a worse prognosis, and combination immunosuppressive therapy was often ineffective for RP-ILD in older patients.

Are common delirium assessment tools appropriate for evaluating delirium at the end of life in cancer patients?

OBJECTIVES: The objectives of this study are to investigate how many advanced cancer patients became unconscious or non-communicative after pharmacological treatment for delirium, and to explore whether existing delirium assessment tools can successfully evaluate its severity at the end of life. METHODS: This was a secondary analysis of a registry study that examined the efficacy and safety of antipsychotics for advanced cancer patients with delirium. A total of 818 patients were recruited from 39 specialized palliative care services in Japan. The severity of delirium was measured using the Richmond Agitation-Sedation Scale-Palliative care version, the Delirium Rating Scale-Revised-98 (DRS-R-98), and the Nursing Delirium Screening Scale (Nu-DESC) on Day 3. Data from 302 patients with motor anxiety with an Agitation Distress Scale score ≥2 on Day 0 were analyzed for this study. The patients were categorized into four treatment response groups: complete response (CR: no agitation and fully communicative), partial response (PR: no/mild agitation and partially communicative), unconscious/non-communicative (UC), and no change (NC). RESULTS: On Day 3, 29 (10%; 95% confidence intervals [CI], 7-13) and 2 (1%; 95% CI, 0-2) patients became unconscious and non-communicative, respectively. Forty-four patients were categorized as CR, 97 as PR, 31 as UC, and 96 as NC. The scores of the DRS-R-98 and Nu-DESC in the UC group were rated higher than patients in the NC group were. CONCLUSIONS: A considerable number of cancer patients with delirium became unconscious or non-communicative. Existing delirium assessment tools may be inappropriate for measuring the severity of delirium in end-of-life.

Factors associated with suicidal ideation in patients with multiple myeloma.

Patients with multiple myeloma are at risk of suicide. The study objective was to investigate the clinical risk factors of suicidal ideation among multiple myeloma patients. Consecutive inpatients with a new primary diagnosis of multiple myeloma were recruited. Patients were asked to complete the Patient Health Questionnaire-9 to measure suicidal ideation and depression. Patient demographic and biomedical characteristics (age, gender, education, marital status, employment, performance status and cancer stage) and pain and depression scores were analyzed as potential factors associated with suicidal ideation. Of the 79 patients, 10 [12.6% (95% confidence interval: 7-22)] had suicidal ideation. The results of a logistic regression analysis showed that being unmarried, less advanced cancer stage and depression were significantly associated with the presence of suicidal ideation. These findings suggest that a non-negligible proportion of patients with multiple myeloma experience suicidal ideation and that several multidimensional factors are significantly associated.

Depressive symptoms during the first month of chemotherapy and survival in patients with hematological malignancies: A prospective cohort study.

OBJECTIVE: The objective of the study is to investigate depressive symptoms before and after the initiation of chemotherapy and their impact on overall survival (OS) among patients with hematological malignancies. METHODS: We performed a prospective analysis of consecutive patients with newly diagnosed malignant lymphoma or multiple myeloma enrolled between September 2010 and March 2016. We evaluated depression symptoms at two time points: before starting chemotherapy (T1) and 1 month later (T2), using PHQ-9 and known prognostic factors. We allocated participants with depressive symptoms at T1 and/or T2 to a depression group that was subdivided as follows: new depressive symptoms at T2, ("new-onset"), remission of depressive symptoms at T2 ("remission"), and persistent depressive symptoms from T1 to T2 ("persistent"). The main outcome, OS, was evaluated using Kaplan-Meier methods and multivariate Cox proportional hazards modeling. RESULTS: Of the 294 eligible participants, we analyzed 255 patients, including 83 with depression. There were 19 participants in the new-onset, 38 in the remission, and 26 in the persistent depression group. The OS of participants with depression was significantly shorter than that of those without depression (adjusted hazard ratio [AjHR] 2.43; 95% confidence interval [CI] 1.43-4.12; P < .001). Using the never-depressive symptoms group as a reference group, AjHRs were as follows: new-onset, 1.91 (95% CI, 0.77-4.75; 0.166); remission, 2.98 (95% CI, 1.55-5.74; 0.001), and persistent, 2.17 (95%CI, 1.01-4.68; 0.047). CONCLUSIONS: Among patients with mature lymphoid malignancy, the group with depression at baseline had a poorer survival, both in the group that remained depressive and the group that recovered from depressive symptoms.

What is the appropriate communication style for family members confronting difficult surrogate decision-making in palliative care?: A randomized video vignette study in medical staff with working experiences of clinical oncology.

BACKGROUND: The family members of terminally ill patients are often requested to make difficult surrogate decisions during palliative care. This study sought to clarify the appropriate communication style for physicians as perceived by family members confronting difficult surrogate decision-making. METHODS: This experimental psychological study used scripted videos. In the videos, the physician described treatment options including continuous deep sedation to the family members of patients with cancer and terminal delirium using an autonomous or paternalistic style. Medical professionals with clinical experience in oncology were randomly assigned to either group viewing the videos. The primary outcomes were physician compassion, decisional conflict and emotion scores. We also evaluated the communication style preference. RESULTS: In total, 251 participants completed this study. Although participants in both groups reported high physician compassion, participants in the autonomous style group reported lower compassion scores (reflecting higher physician compassion) (mean 15.0 vs. 17.3, P = 0.050), lower decisional conflicts scores (51.1 vs. 56.8, P = 0.002) and comparable emotions compared with those in the paternalistic style group. Seventy-six percent of participants preferred the autonomous style. CONCLUSIONS: Regarding difficult surrogate decision-making, the autonomous style might be more appropriate than the paternalistic style. However, various factors, such as family members' communication style preferences, family members' values, physician-family relationships and ethnic cultures, should be considered.

Factors associated with a preference for disclosure of life expectancy information from physicians: a cross-sectional survey of cancer patients undergoing radiation therapy.

PURPOSE: This study aimed to investigate experiences and preferences for disclosure of life expectancy, agreement between them, and the factors associated with preferences for disclosure of life expectancy with physicians among cancer patients undergoing radiation therapy. METHODS: Cancer patients aged 20 years or older were consecutively sampled when they started radiation therapy at two university hospitals. Patients completed self-administered questionnaires concerning their experiences of and preferences for disclosure of life expectancy, treatment decision-making, psychological distress, physical symptoms, sociodemographic and medical factors, physician's communication style, and provision of psychological, physical, and practical support. RESULTS: Among the 226 respondents (response rate: 58%) who responded, 54% experienced disclosure of life expectancy, and 45% preferred it. The agreement is 65%. Eighty-five percent recognized their aim of radiation therapy as curative. A univariate analysis indicated that having a full/part-time job and wishing to leave treatment decisions to doctors were significantly associated with preference for disclosure of life expectancy, but psychological distress was not. A multiple regression analysis revealed that having a full-time/part-time job was significantly associated with preference of communication about life expectancy. CONCLUSIONS: Fifty-four percent of the patients experienced and 45% of the patients preferred disclosure of life expectancy. The agreement is moderate. Our results show that there was a significant association between employment status and patient's preference for disclosure of life expectancy with physicians. Communication of prognosis is difficult but whether a patient continues to work or not may be an indicator of preference.

Goals of care and treatment in terminal delirium: A qualitative study of the views and experiences of healthcare professionals caring for patients with cancer.

OBJECTIVE: This study explores the views of healthcare professionals regarding care and treatment goals in irreversible terminal delirium and their effect on patients and caregivers. METHOD: We conducted a qualitative interview study of healthcare professionals (palliative care physician, oncologist, psycho-oncologist, and clinical psychologist) engaged in the treatment of terminally ill cancer patients. We assessed the views of healthcare workers regarding treatment goals in terminal delirium and their effect on patients and their families. RESULT: Of the 21 eligible healthcare professionals, 20 agreed to participate in this study. Three of the professionals had experience with treating terminal delirium as family caregivers. We identified five important aspects of treatment goals in terminal delirium based on the views of healthcare professionals: (1) adequate management of symptoms/distress, (2) ability to communicate, (3) continuity of self, (4) provision of care and support to families, and (5) considering a balance (between symptom alleviation and maintaining communication; between symptom alleviation and family preparations for the death of patients; balance between specific treatment goals for delirium and general treatment goals). SIGNIFICANCE OF RESULTS: According to the views of healthcare workers questioned in this study, goals of care and treatment in terminal delirium are multidimensional and extend beyond simply controlling patient symptoms.

Utilization of population pharmacokinetics in drug development and provision of the results to healthcare professionals
.

OBJECTIVE: The aim of this research is to understand the level of utilization of population pharmacokinetics (PPK) in drug development in the United States of America (US) and Japan, and to discuss what kind of PPK information should be provided to healthcare professionals. METHODS: Information on PPK was identified on the label, package insert, and pharmaceutical evaluation report disclosed by the US Food and Drug Administration and the Pharmaceutical Medical Devices Agency of Japan for new molecular entities approved between January 2012 and December 2015. RESULTS: Between January 2012 and December 2015, 152 new molecular entities were approved in the US and 176 in Japan. The proportion of documents using PPK data in the US increased each year, but in Japan the proportion plateaued. The proportion of US labels and that of Japanese package inserts containing PPK parameters was 37.2% (32/86) and 41.9% (13/31), respectively. CONCLUSIONS: PPK use in drug development in the US is increasing each year, there is no similar increase occurring in Japan. We expect that the use of pharmacometrics, including PPK and PPK/pharmacodynamics (PD), will become more common in drug development, and that by sharing the PPK model obtained from clinical trial promptly within medical practice they can be effectively utilized in individualized drug administration plans.

Does cognitive decline decrease health utility value in older adult patients with cancer?

AIM: Cognitive decline is common among older adults with cancer. The present study aimed to investigate the impact of cognitive decline on health utility value in older adults suffering from cancer. METHODS: Consecutive patients aged 65 years or older with a primary diagnosis of malignant lymphoma or multiple myeloma were recruited. Patients were asked to complete the EuroQoL-5 (EQ-5D) scale to measure health utility and the Mini-Mental State Examination to assess cognitive decline. The potential impact of cognitive decline was investigated with univariate analysis. A multivariate regression analysis was conducted to control for potential confounding factors. RESULTS: Complete data were obtained from 87 patients, 29% of whom had cognitive decline. The mean ± SE EQ-5D score for patients with cognitive decline was significantly lower than that for those without cognitive decline (0.67 ± 0.04 vs 0.79 ± 0.03, t = 2.38, P = 0.02). However, multiple regression analysis showed that cognitive decline was not significantly associated with EQ-5D scores. Female sex and lower performance scores (worse physical condition) were significantly associated with EQ-5D scores. CONCLUSIONS: Cognitive decline may be involved in decreased health utility value in older adult patients with cancer. However, this effect does not seem to be independent, and the patient's physical condition may be a relevant confounding factor.

Current Status of Distress Screening in Designated Cancer Hospitals: A Cross-Sectional Nationwide Survey in Japan.

BACKGROUND: The purpose of this study was to investigate the current status of distress screening implementation in Japanese designated cancer hospitals. SUBJECTS AND METHODS: This was a cross-sectional observational study. Palliative care team representatives in all designated cancer hospitals in Japan completed an ad hoc questionnaire. Demographic data in 2014 were obtained from the Ministry of Health, Labour and Welfare in Japan. RESULTS: Of 422 institutions, 389 responded (92%) and data were obtained from 379 (90%). Approximately 90% of institutions had implemented a distress screening program at some level, and approximately 60% had just started screening. Among those institutions that screened, 77% provided individualized triage to specialized services within the institutions, whereas 60% did not routinely follow-up with patients who had positive screening results. The estimated median percentage of screened patients referred to palliative care teams was 0.4% in outpatient settings and 6.3% in inpatient settings. Although 68% of respondents perceived that screening was useful overall, they also reported difficulties when conducting screening with patients, reporting "no established effective treatment for problems screened" (66%), "patients complain it is difficult to express their distress using scales" (58%), and that it was "difficult to manage screened problems because of lack of time" (49%). Eight perceived barriers to implementing distress screening programs in hospitals were identified; a lack of human resources ranked highest. CONCLUSIONS: Implementation of distress screening in designated cancer hospitals in Japan has just begun. Policymakers should acknowledge that screening can be beneficial for patients when it is implemented with appropriate resources and established methods.

Effectiveness of a psycho-oncology training program for oncology nurses: a randomized controlled trial.

OBJECTIVE: Oncology nurses are expected to play an important role in psychosocial care for cancer patients. The aim of this study was to examine whether a novel training program aimed at enhancing oncology nurses' ability to assess and manage common psychological problems in cancer patients would improve participants' self-reported confidence, knowledge, and attitudes regarding care of patients with common psychological problems (trial register: UMIN000008559). METHODS: Oncology nurses were assigned randomly to either the intervention group (N = 50) or the waiting list control group (N = 46). The intervention group received a 16-h program, the content of which focused on four psychological issues: normal reactions, clinically significant distress, suicidal thoughts, and delirium. Each session included a role-play exercise, group work, and didactic lecture regarding assessment and management of each problem. Primary outcomes were changes in self-reported confidence, knowledge, and attitudes toward the common psychological problems between pre-intervention and 3 months post-intervention. Secondary outcomes were job-related stress and burnout. Intervention acceptability to participants was also assessed. RESULTS: In the intervention group, confidence and knowledge but not attitudes were significantly improved relative to the control group. No significant intervention effects were found for job- related stress and burnout. A high percentage (98%) of participants considered the program useful in clinical practice. CONCLUSIONS: This psycho-oncology training program improved oncology nurses' confidence and knowledge regarding care for patients with psychological problems.

Screening for untreated depression in cancer patients: a Japanese experience.

OBJECTIVE: Guidelines for supportive care in cancer patients have recommended routine psychological screening in clinical practice, and a Japanese national project has recommended screening for depression using the Distress and Impact Thermometer. However, a previous study advocating the validity of the Distress and Impact Thermometer may have overestimated its effectiveness, as the study included already-treated patients who were not screening targets. This study re-evaluated the performance and usefulness of the Distress and Impact Thermometer using an adequate sample size and appropriate study design. METHODS: Patients were consecutively recruited at two highly specialized hospitals and three university hospitals in Japan. Inclusion criteria were (i) undergoing aggressive anti-cancer treatment, (ii) the Eastern Cooperative Oncology Group performance status score <3 and (iii) age >20 years. Patients who were receiving psychiatric treatment were excluded from the study. After completing the Distress and Impact Thermometer, patients were evaluated with the gold-standard Composite International Diagnostic Interview by researchers who were blinded to the patients' Distress and Impact Thermometer scores. RESULTS: Forty-four patients (9%) who were receiving psychiatric treatment were excluded. Of 468 subjects included in the final analysis, only 3 had current depression (0.6%). Using cutoff points recommended by the previous study, the positive and negative predictive values were 0.02 and 0.99, respectively. CONCLUSIONS: Our data indicated that screening for untreated depression in cancer patients was not useful in the specific clinical settings that were studied, and such screening should be implemented in appropriate contexts. Since there are no evidence-based recommendations regarding contexts in which psychological screening is essential, further research is needed.

Difference of patient's perceived need in breast cancer patients after diagnosis.

OBJECTIVE: The purpose of this study was to investigate the difference of patients' perceived needs after cancer diagnosis. Differences in quality of life and psychological distress were also examined. METHODS: Ambulatory breast cancer patients who were randomly selected participated in this study. The patients were asked to complete the Short-form Supportive Care Needs Survey, which covers five domains of need (health system and information, psychological, physical, care and support and sexuality needs), the European Organization for Research and Treatment of Cancer QLQ-C 30 and the Hospital Anxiety and Depression Scale. RESULTS: A total of 408 patients were enrolled and distributed into four groups [Group 1 (N = 115)], within 1 year of diagnosis; Group 2 [N = 105], 1-3 years since diagnosis; Group 3 [N = 94], >3 years since diagnosis; and Group 4 [N = 94], recurrence). Significant differences were observed in total, psychological, physical and daily living, and patient care and support needs, as well as in quality of life, whereas there were no significant differences in health system and information, sexuality needs and psychological distress. In general, Groups 1 and 4 had a higher need level and lower quality of life. CONCLUSIONS: Patients' perceived needs and quality of life may vary according to time since cancer diagnosis and the presence of cancer recurrence. The findings suggest that different care for supporting breast cancer survivors after diagnosis should be recommended, and that the time since diagnosis and/or the presence of recurrence may be relevant indicators for providing optimal and individualized care.

Prevalence, course and factors associated with delirium in elderly patients with advanced cancer: a longitudinal observational study.

OBJECTIVE: The aim of this study was to investigate the prevalence of delirium on admission, the course of delirium during a 2-week period after admission and factors associated with delirium on admission, among elderly patients with advanced cancer. METHODS: Patients aged ≥ 65 years with incurable lung or gastroenterological cancer and the Eastern Cooperative Oncology Group Performance Status 2 or greater were continuously sampled after admission to a university hospital. Participants were evaluated for DSM-IV-TR delirium by trained psychiatrists and the delirium subtype was assessed using the Delirium Motor Subtype Scale within 4 days after admission and again 2 weeks later. In addition, we assessed associated factors with delirium on admission. RESULTS: Among 73 eligible patients, complete data were available from 61 on admission and 49 after 2 weeks. Twenty-six patients (43%) met delirium criteria on admission (hypoactive: 58%, unspecified: 35%, hyperactive: 4%, mixed: 4%). Of these, 19 (73%) remained delirious 2 weeks later. Of 35 patients without delirium on admission, 21 (60%) remained delirium-free 2 weeks later and 7(20%) became delirious. Overall, 33/61 (54%) developed delirium at some point during the study. Patients receiving steroids at admission were more likely to have delirium (odds ratio = 5.0; 95% confidence interval = 1.5-16). CONCLUSIONS: Given the high prevalence of the delirium, all patients with advanced cancer should be screened for delirium both on admission and regularly thereafter. In addition, medical staff should be aware that steroid use on admission is an additional indicator of elevated risk for delirium.

Assessing medical decision making capacity among cancer patients: Preliminary clinical experience of using a competency assessment instrument.

OBJECT: This study investigates the usefulness of the Structured Interview for Competency and Incompetency Assessment Testing and Ranking Inventory (SICIATRI) for cancer patients, which is a structured interview that assesses a patient's competency in clinical practice. METHODS: The SICIATRI, originally developed to measure patients' competency to give informed consent, were administered referred cancer patients who needed for assessing medical decision making capacity. The usefulness of the SICIATRI was investigated retrospectively. Recommendation for modification of the SICIATRI for cancer patients if applicable were made by the research team. RESULTS: Among the 433 cancer patients referred for psychiatric consultation, 12 were administered the SICIATRI and all of the administration were conducted without big problems. All patients were 60 years or older. The most common purpose for competency evaluation was to analyze patients' understanding of the anti-cancer treatment proposed by oncologists, followed by their refusal of the treatment. Half of the patients (n = 6) were diagnosed with delirium and three among them were judged as having the most impaired status of a patient's competency. Two patients (17%) were diagnosed with major depression and another two (17%) were mental retardation and each one patient was diagnosed with dementia and past history of alcohol dependence. Among 6 patients without delirium 5 subjects including a dementia patient were judged as fully competent. Total of 5 small potential modifications of the SICIATRI for its use with Japanese cancer patients were recommended. SIGNIFICANCE OF RESULTS: Our experience suggests that the SICIATRI is a useful instrument for psycho-oncology clinical practice.
