Health-related quality of life in patients with advanced cancer who express a wish to hasten death: A comparative study

Abstract

Background: Some evidence suggests the wish to hasten death is related to poor health-related quality of life. Deficits in perceived dignity and self-efficacy are risk factors for wish to hasten death that also impact health-related quality of life.

Aim: To compare perceived health-related quality of life, dignity and self-efficacy in patients with advanced cancer who either do (case group) or do not (control group) express a wish to hasten death. Cases and controls were matched on sociodemographic and functional characteristics.

Design: A comparative cross-sectional study.

Participants: A total of 153 adult patients with advanced cancer were assessed for wish to hasten death using the Desire for Death Rating Scale. Scores ⩾1 indicate some degree of wish to hasten death (case group, n = 51), and score = 0 implies no wish to hasten death (control group, n = 102). Assessments included health-related quality of life using the European Organization for Research and Treatment of Cancer Quality-of-Life Core 15-Item Palliative Questionnaire, perceived loss of dignity using the Patient Dignity Inventory and self-efficacy using the General Self-Efficacy Scale.

Results: Patients with a wish to hasten death had worse emotional functioning (p < 0.001), greater perceived loss of dignity (p < 0.001) and lower self-efficacy (p = 0.001). There was no difference in most physical symptoms. Perceived overall health-related quality of life was significantly worse for those with a clinically relevant wish to hasten death (p = 0.023) and marginally worse for the case group than the control group (p = 0.052).

Conclusion: Patients with wish to hasten death showed lower perceived dignity, self-efficacy and emotional quality of life than patients without wish to hasten death without necessarily perceiving worse physical symptoms.
