Pain and desire for hastened death in terminally ill cancer patients.

The purpose of this study was to assess the relationship between pain and the desire for hastened death in terminally ill cancer patients. The participants were 120 terminally ill cancer patients under palliative treatment from June 2003 to November 2004. Patients completed a pain assessment tool, the Greek Brief Pain Inventory (G-BPI), and a self-report measure of the desire for hastened death, the Greek Schedule of Attitudes Toward Hastened Death (G-SAHD). Moderate but statistically significant associations were found between some of the severity and interference items of G-BPI and G-SAHD; more specifically, between G-SAHD and G-BPI3, "worst pain in the last 24 hours" (r = 0.279, P = .002); G-SAHD and G-BPI4, "least pain in the last 24 hours" (r = 0.253, P = .005); and G-SAHD and G-BPI5, "average pain in the last 24 hours" (r = 0.283, P = .002). A stronger association was revealed between G-SAHD and G-BPI8, "relief provided by pain treatment and medications in the last 24 hours" (r = -0.326, P = .000). Multiple regression analyses including the enter model and the forward model were conducted. According to the enter model, the strongest predictors of hastened death were items G-BPI6, "current pain"; G-BPI8, "relief provided by pain treatment and medications in the last 24 hours"; G-BPI9i, "interference of pain in general activity"; and G-BPI9iii, "interference of pain in walking." According to the forward model, significant predictors of the desire for death were items G-BPI5, "average pain in the last 24 hours"; G-BPI6, "current pain"; G-BPI9i, "interference of pain in general activity"; and G-BPI9ii, "interference of pain in mood," all of which were statistically significant (P = .000-.042). Pain appeared to have a statistically significant relationship with the desire for hastened death. Effective treatment by healthcare professionals should be provided to reduce pain and cancer-related symptoms as well as the desire for hastened death.
