Discrepancy between treatment goals documentation by oncologists and their understanding among cancer patients under active treatment with chemotherapy

Abstract

Objective/Background Discussion of treatment goals between oncologists and patients is challenging. Patients frequently misunderstand goals of therapy. There are several methods to document goals of chemotherapy, however, and are frequently not incorporated into patient charts. Methods/Design Cancer patients receiving their first cycle of chemotherapy were interviewed. Patients’ recall of discussions with their oncologist regarding therapy intent was assessed and compared to documentation. An adjusted McNemar's test was utilised. A one‐sample proportion test was used to evaluate whether the overall observed rate of discordance was significantly different from the proposed 33% rate; a rate posited as a threshold too high in the clinical sense. Results Two hundred and seven eligible patients were interviewed. Oncologist identified treatment goals were not documented in 24.6% of cases and had to be excluded. There was not a significant difference in the directionality of discordance present. Inter‐rater agreement between patient and oncologist was found to be adequate (κ = 0.64). The overall rate of discordance (17.29%) was found to be significantly less than the proposed acceptable level of 33% (p < 0.01). Upon univariable analysis, age, gender, marital and employment status were not found to be associated with discordance. Conclusions Discordance between treatment goals documentation and their understanding exists, indicating continued miscommunication between the patient and oncologist.

Barriers of and strategies for shared decision‐making implementation in the care of metastatic breast cancer: A qualitative study among patients and healthcare professionals in an Asian country

“…Our findings corroborate those of previous studies that have reported decisional conflicts and discrepancies in treatment goals in healthcare provider–patient–caregiver communication. 28 , 29 , 30 , 31 , 32 There also exists a discordance in patients' healthcare needs assessment between healthcare providers and patients, whereby patients expected encouragement and spiritual support, but healthcare providers focused on treatment efficacy. 33 As one participant mentioned, the training of healthcare providers focuses on healthcare outcomes and not the patient's life goals.…”

Preferences of bereaved family members on communication with physicians when discontinuing anticancer treatment: referring to the concept of nudges

“…The participants were further asked whether the patients were offered the option of continuing their current treatment or starting other anticancer treatment at the time they decided of not receiving anticancer treatment. The participants who indicated that a choice was presented were asked for multiple responses about their understanding of the purpose of the presented treatment ( 31 ). The response options were as follows: (i) cancer cure, (ii) life expectancy extension, (iii) symptom palliation and (iv) other.…”

Successful Strategies and Areas of Improvement–Lessons Learned from Design and Conduction of a Randomized Placebo-Controlled Trial in Palliative Care, ‘Palliative-D’

“…The concept of palliative care itself may be challenging for patients and relatives to grasp [57] and is generally regarded by the public of being representative of the last days of life [58]. Further, the introduction of new oncological treatment modalities and differences between how oncology specialists, palliative care professionals, and patients use terminology related to disease phase may lead to misperceptions [59][60][61][62]. In this study, this yielded an ethical dilemma, as revealing information concerning estimated lifespan could affect the patient negatively.…”
