The independent factors predictive of WTD were (1) knowledge of approximate prognosis (OR=4.78 95% CI 1.20 to 10.8 p=0.001) (2) symptom burden (OR=1.05 95% CI 1.00 to 1.09 p=0.038) and (3) the Demoralisation Scale subsection ‘lack of meaning and purpose in life’ (OR=1.61 95% CI 1.30 to 1.99 p=0.000). The prevalence of WTD in the sample was 18%, with 8 out of 36 patients reporting HDI. The analysis used univariate and multivariate logistic regression. Sociodemographic data and data related to symptom burden (Edmonton Symptom Assessment System-Revised), depressive and anxious symptoms (Hospital Anxiety and Depression Scale), demoralisation (Spanish version of the Demoralisation Scale), perceived loss of dignity (Patient Dignity Inventory) and WTD (Assessing Frequency and Extent of Desire to Die) were collected.
This is a subanalysis of a larger cross-sectional study conducted on patients experiencing advanced illness (N=201). The aim of this study is to identify the predictive factors for WTD and hastening death intention (HDI) in Spanish patients with advanced illness. The wish to die (WTD) is a complex experience sometimes accompanied by intention to hasten death.
