Abstract

Although sedation for existential distress has been actively discussed in the palliative care literature, empirical reports are limited. A retrospective cohort study was performed to clarify the physical conditions of terminally ill cancer patients who expressed existential distress and received sedation. Of 248 consecutive hospice inpatients, 20 patients expressed a belief that their lives were meaningless and received sedation. The target symptoms for sedation were dyspnea (n = 10), agitated delirium (n = 8), and pain (n = 1). Only one patient received sedation for psychological distress alone, although physical symptoms were acceptably relieved. The Palliative Performance Scale just before sedation was 10 (n = 7), 20 (n = 11), 30(n = 1), and 40(n = 1). All but one patient could take nourishment orally of only mouthfuls or less. Edema, dyspnea at rest, and delirium were observed in 10, 13, and 14 cases, respectively. The Palliative Prognostic Index was greater than 6.0 in all but one case with a mean of 12 +/- 3.3. In conclusion, in our practice, sedation was principally performed for physical symptoms of cancer patients in very late stages. Further research is encouraged to establish standard therapy for existential distress of the terminally ill.

The Palliative Prognostic Index: a scoring system for survival prediction of terminally ill cancer patients.

S. Inoue, S Chihara, J Tsunoda … (1999)

Although accurate prediction of survival is essential for palliative care, few clinical methods of determining how long a patient is likely to live have been established. To develop a validated scoring system for survival prediction, a retrospective cohort study was performed with a training-testing procedure on two independent series of terminally ill cancer patients. Performance status (PS) and clinical symptoms were assessed prospectively. In the training set (355 assessments on 150 patients) the Palliative Prognostic Index (PPI) was defined by PS, oral intake, edema, dyspnea at rest, and delirium. In the testing sample (233 assessments on 95 patients) the predictive values of this scoring system were examined. In the testing set, patients were classified into three groups: group A (PPI 4.0). Group B survived significantly longer than group C, and group A survived significantly longer than either of the others. Also, when a PPI of more than 6 was adopted as a cut-off point, 3 weeks' survival was predicted with a sensitivity of 80% and a specificity of 85%. When a PPI of more than 4 was used as a cutoff point, 6 weeks' survival was predicted with a sensitivity of 80% and a specificity of 77%. In conclusion, whether patients live longer than 3 or 6 weeks can be acceptably predicted by PPI.

Desire for death in the terminally ill.

N Mowchun, Jonathan M. Levitt, Richard Wilson … (1995)

Euthanasia and physician-assisted suicide have become prominent medical and social issues. This study investigated the prevalence of the desire for death in terminally ill patients, the stability of this desire over time, and its association with psychiatric disorders. Two hundred terminally ill inpatients were given semistructured interviews that assessed their desire for death and evaluated them for major and minor depressive episodes according to the Research Diagnostic Criteria. Each patient also completed a short form of the Beck Depression Inventory and provided ratings of pain and social support. When possible, patients who expressed a desire for death received a follow-up interview after a 2-week interval. Although occasional wishes that death would come soon were common (reported by 44.5% of the patients), only 17 (8.5%) of these individuals acknowledged a serious and pervasive desire to die. The desire for death was correlated with ratings of pain and low family support but most significantly with measures of depression. The prevalence of diagnosed depressive syndromes was 58.8% among patients with a desire to die and 7.7% among patients without such a desire. Follow-up interviews were conducted with six patients; in four cases, the desire to die had decreased during the 2-week interval. The desire for death in terminally ill patients is closely associated with clinical depression--a potentially treatable condition--and can also decrease over time. Informed debate about euthanasia should recognize the importance of psychiatric considerations, as well as the inherent transience of many patients' expressed desire to die.

Depression, Hopelessness, and suicidal ideation in the terminally ill.

Harvey Chochinov, Keith Wilson, Murray W Enns … (1998)

This study investigated the mediational hypothesis of hopelessness in predicting suicidal ideation in a group of 196 patients with advanced terminal cancer. Each patient underwent a semistructured interview to assess hopelessness and suicidal ideation, and also completed the Beck Depression Inventory (short form). Hopelessness was correlated more highly with suicidal ideation than was the level of depression. In multiple linear-regression analyses, hopelessness contributed uniquely to the prediction of suicidal ideation when the level of depression was controlled. For health care providers attending to the needs of dying patients, hopelessness appears to be an important clinical marker of suicidal ideation in this vulnerable patient population.
