Background: There is ongoing debate on whether continuous deep sedation (CDS) for psycho-existential suffering is appropriate. Objective: We aimed to (1) clarify clinical practice of CDS for psycho-existential suffering and (2) assess its impact on patients' survival. Methods: Advanced cancer patients admitted to 23 palliative care units in 2017 were consecutively enrolled. We compared patients' characteristics, CDS practices, and survival between those receiving CDS for psycho-existential suffering ± physical symptoms and only for physical symptoms. Results: Of 164 patients analyzed, 14 (8.5%) received CDS for psycho-existential suffering ± physical symptoms and only one of them (0.6%) solely for psycho-existential suffering. Patients receiving CDS for psycho-existential suffering, compared with those only for physical symptoms, were likely to have no specific religion (p = 0.025), and desired (78.6% vs. 22.0%, respectively; p < 0.001) and requested a hastened death more frequently (57.1% vs. 10.0%, respectively; p < 0.001). All of them had a poor physical condition with limited estimated survival, and mostly (71%) received intermittent sedation before CDS. CDS for psycho-existential suffering caused greater physicians' discomfort (p = 0.037), and lasted for longer (p = 0.029). Dependency, loss of autonomy, and hopelessness were common reasons for psycho-existential suffering that required CDS. The survival time after CDS initiation was longer in patients receiving it for psycho-existential suffering (log-rank, p = 0.021). Conclusion: CDS was applied to patients who suffered from psycho-existential suffering, which often associated with desire or request for a hastened death. Further studies and debate are warranted to develop feasible treatment strategies for psycho-existential suffering. [ABSTRACT FROM AUTHOR]

Background: The objective prognostic score (OPS) needs to be modified to reflect practical palliative care circumstances. Objectives: We aimed to validate modified models of OPS with few or no laboratory tests for patients with advanced cancer. Design: An observational study was performed. Setting/Subjects: A secondary analysis of an international, multicenter cohort study of patients in East Asia was performed. The subjects were inpatients with advanced cancer in the palliative care unit. Measurements: We developed two modified OPS (mOPS) models to predict two-week survival: mOPS-A consisted of two symptoms, two objective signs, and three laboratory results, while mOPS-B consisted of three symptoms, two signs, and no laboratory data. We compared the accuracy of the prognostic models using sensitivity, specificity, and area under the receiver operating characteristic curve (AUROC). Calibration plots for two-week survival and net reclassification indices (NRIs) were compared for the two models. Survival differences between higher and lower score groups of each model were identified by the log-rank test. Results: We included a total of 1796 subjects having median survival of 19.0 days. We found that mOPS-A had higher specificity (0.805–0.836) and higher AUROCs (0.791–0.797). In contrast, mOPS-B showed higher sensitivity (0.721–0.725) and acceptable AUROCs (0.740–0.751) for prediction of two-week survival. Two mOPSs showed good concordance in calibration plots. Considering NRIs, replacing the original OPS with mOPSs improved overall reclassification (absolute NRI: 0.47–4.15%). Higher score groups of mOPS-A and mOPS-B showed poorer survival than those of lower score groups (p < 0.001). Conclusions: mOPSs used reduced laboratory data and had relatively good accuracy for predicting survival in advanced cancer patients receiving palliative care. [ABSTRACT FROM AUTHOR]

Background: Little is known about accuracy and confidence of clinicians' prediction of survival (CPS) in East-Asian countries. Objective: We aimed to examine accuracy of CPS for 7-, 21-, and 42-day survival in palliative inpatients and its association with prognostic confidence. Design: An international prospective cohort study in Japan (JP), Korea (KR), and Taiwan (TW). Setting/Subjects: Subjects were inpatients with advanced cancer admitted to 37 palliative care units in three countries. Measurements: Discrimination of CPS was investigated through sensitivity, specificity, overall accuracy, and area under the receiver operating characteristics curves (AUROCs) according to 7-, 21-, and 42-day survival. The accuracies of CPS were compared with those of Performance Status-based Palliative Prognostic Index (PS-PPI). Clinicians were instructed to rate confidence level on a 0–10-point scale. Results: A total of 2571 patients were analyzed. The specificity was highest at 93.2–100.0% for the 7-day CPS, and sensitivity was highest at 71.5–86.8% for the 42-day CPS. The AUROCs of the seven-day CPS were 0.88, 0.94, and 0.89, while those of PS-PPI were 0.77, 0.69, and 0.69 for JP, KR, and TW, respectively. As for 42-day prediction, sensitivities of PS-PPI were higher than those of CPS. Clinicians' confidence was strongly associated with the accuracy of prediction in all three countries (all p-values <0.01). Conclusions: CPS accuracies were highest (0.88–0.94) for the seven-day survival prediction. CPS was more accurate than PS-PPI in all timeframe prediction except 42-day prediction in KR. Prognostic confidence was significantly associated with the accuracy of CPS. [ABSTRACT FROM AUTHOR]

Background: Symptoms are not typically part of established various prognostic factors and scoring systems but are among the most frequently assessed issues in patient care. Objectives: To evaluate that, changes in symptoms can provide additional useful prognostic information. Design: A secondary analysis of an international cohort study in Japan, Korea, and Taiwan. Setting/Subjects: Subjects were adult patients with advanced cancer (n = 2074) who were admitted to 37 palliative care units (PCUs) in 3 countries from January 2017 to September 2018. Measurements: Symptoms (dyspnea, fatigue, dry mouth, and drowsiness) were assessed at admission and one-week later. Dyspnea was assessed by the presence of resting and exertional dyspnea, whereas other symptoms were assessed using the Integrated Palliative care Outcome Scales (IPOS) (range 0–4). For analysis, we grouped patients by symptom change, as either Improved, Stable, or Worsened (by having at least a one increment decrease, no change, or at least a one increment increase, respectively). Results: Worsened groups had the shortest survival (median survival 15–21 days) compared with those with Improved (median survival 23–31 days) and Stable symptoms (median survival 27–29 days) across all four symptoms (dyspnea, fatigue, dry mouth, and drowsiness). Survival differences were statistically significantly different across all three groups for all symptoms (all p < 0.001). Interestingly, Improved symptoms were associated with similar survival compared with Stable groups, with no statistical differences. Conclusions: Worsened symptoms at one week after admission were useful predictors of survival for patients with advanced cancer in PCUs during the final weeks of life. Longitudinal assessments are needed to reflect passage of time as well as impact of treatments. [ABSTRACT FROM AUTHOR]

Background: Patients with life-limiting illnesses frequently experience urinary difficulties, and urinary catheterization is one of the interventions for managing them. However, evidence supporting the effects of urinary catheters on the quality of death (QoD) is lacking in this population. Objectives: To investigate whether urinary catheterization affects QoD in patients with advanced cancer in palliative care units. Design: A secondary analysis of a multicenter, prospective cohort study. Setting/Subjects: The study enrolled consecutive patients with advanced cancer admitted to palliative care units in Japan between January and December 2017. Those who were not catheterized on admission and who died while in a palliative care unit were analyzed. Measurements: QoD was evaluated at death using the Good Death Scale (GDS). Results: Of 885 patients, 297 (33.6%) were catheterized during their palliative care unit stay. Females and patients with a long palliative care unit stay were more likely to be catheterized. In inverse probability-weighted propensity score analysis, patients with urinary catheterization during their palliative care unit stay had higher total GDS scores than those without catheterization (coefficient 0.410, 95% confidence interval 0.068–0.752). In subgroup analyses stratified by sex, age, and length of palliative care unit stay, urinary catheterization was associated with higher total GDS scores in patients younger than 65 years of age and those who died after a palliative care unit stay of 21 days or fewer. Conclusions: This study suggested that urinary catheterization during a palliative care unit stay may have a positive impact on overall QoD in patients with advanced cancer. This study was registered in the UMIN Clinical Trials Registry (UMIN000025457). [ABSTRACT FROM AUTHOR]

Context: Some patients require continuous deep sedation (CDS) for refractory symptoms despite intensive palliative care. The principle of proportionality is proposed on the basis of clinical decisions, but no validated tools to assist such decision making are available. Aim: To develop a scoring system to determine whether CDS is proportionally appropriate. Subjects and Methods: A secondary analysis of a nationwide questionnaire survey of Japanese palliative care specialists was performed. Physicians were asked to rate the degree that they believed CDS to be appropriate in a total of 27 scenarios based on a combination of 3 factors with 3 levels: (1) the estimated survival (days, weeks, and months), (2) the patient's wish (clear and consistent, somewhat unclear and/or inconsistent, and unclear or inconsistent), and (3) confidence in refractoriness of the symptom (definite, probable, and unsure). Based on logistic regression analyses, a scoring system with two formulas (the proportionality score to determine that continuous deep sedation is appropriate [ProScoreCDS-appropriate] and proportionality score to determine that continuous deep sedation is inappropriate [ProScoreCDS-inappropriate]) to predict specialists' decision that CDS is appropriate or inappropriate was developed. The accuracy of the formulas was investigated. Results: Among 695 palliative care specialists, 469 returned the questionnaire (response rate, 69%) and 440 were analyzed. Logistic regression analyses identified that all three factors were significantly associated with physicians' decisions about the appropriateness of performing CDS. Using weighted value, the total score ranged from 3 to 67 for ProScoreCDS-appropriate, and 3 to 27 for ProScoreCDS-inappropriate. The area under the curve (AUC) values of ProScoreCDS-appropriate and ProScoreCDS-inappropriate were 0.88 (95% confidence interval [CI], 0.87–0.89) and 0.81 (95% CI, 0.81–0.82), respectively. Using cutoff points of 41 and 14, sensitivity and specificity were 68.6% and 88.9% for ProScoreCDS-appropriate and 67.7% and 76.0% for ProScoreCDS-inappropriate, respectively. Conclusion: A scoring system to determine whether CDS is proportionally appropriate can be constructed, and a further study to develop a clinical tool is promising. [ABSTRACT FROM AUTHOR]
