The predictors of information needs and different views of patients and relatives on disclosure and treatment participation: A multicentric survey study

Abstract

e20526 Background: We wanted to explain if the views of patients and their relatives differed on disclosure and treatment participation or not, and if so, to evaluate the predictors of this difference. Methods: The survey aimed to unveil the attitude of patients and their relatives in 3 domains; disclosure of diagnosis, prognosis and participation to treatment. Multinomial logistic regression models with forward selection procedure were constructed for the multivariate analysis to explain the origins of discordance in these domains. Results: A total of 1,052 consecutive cases (526 patients and their 526 relatives) were interviewed. The relatives, when they were asked to imagine themselves with a new diagnosis of cancer, opted for disclosure of diagnosis, prognosis, and participation to treatment in 92.4%, 84.6%, and 86.3% of cases. When patients were asked for their information needs in disclosure of diagnosis, prognosis, and participation to treatment, 83.8%, 70.2%, and 70% wanted disclosure, whereas, their relatives wanted disclosure for their patients in these 3 domains in 32.9%, 40.5%, and 60.3% of cases, respectively. The multivariate predictors of discordance for disclosure of diagnosis between patients and relatives were patient age, social insurance, and oncology centers (P=0.003, 0.007, and <0.001, respectively). The associates of discordance for disclosure of prognosis were again oncology centers and relatives’ relationship with the patients (P<0.001 and 0.012). Likewise, the correlates of discordance for treatment participation were again oncology centers and patient age (P<0.001 and 0.016). Conclusions: Information needs of patients and their relatives, when they imagine themselves as cancer patients, are quite similar. However, relatives are not in favor of disclosure to their patients of diagnosis and prognosis, moreover, in spite of this, they want their patients to actively participate in treatment decisions. We believe this paradox represents a desire of the relatives to escape from responsibility and emotional burden of the care of the cancer patients. This paradox, in addition, is a threat to a healthy patient and physician communication. No significant financial relationships to disclose.
