Communication and understanding of prognosis among stage IV lung and GI cancer patients
9024 Background: Patients' understanding of prognosis is essential to informed decision making about treatment options. There is little data on what prognostic information oncologists communicate to patients and what patients actually understand about their prognosis. Methods: We audio taped consultations between 90 newly diagnosed stage IV non small cell lung cancer patients and stage IV GI cancer patients and medical oncologists at academic teaching hospitals. Interactions were audio taped until patients arrived at a treatment decision. Audiotapes were digitized, coded and analyzed using the RIAS system. All conversation relating to prognosis was blocked, coded and analyzed. After meeting with an oncologist patients were surveyed about their understanding of prognosis and desire for information about life expectancy. Results: 276 patients were contacted of whom 190 consented to participate. 87 patients were ineligible, 13 patients withdrew from the study, and complete data were obtained on 90 patients. The mean age of participants was 62 years (±11), 65% were women. Analysis of the audiotapes revealed that in 78% of cases oncologists told patients that their cancer was not curable. When patients were surveyed, however, only 32% of those who were told that their cancer was not curable actually understood that there was no cure for their cancer (CI 0.19–0.45). Patients’ age, gender, education, and marital status were not associated with an understanding of prognosis. Patient factors associated with understanding of prognosis included a desire for good and bad medical information (CI 0.75–0.99; p<0.0001), an interest in knowing the likelihood that treatment would cure their disease (CI 0.54–0.94; p<0.01), and a belief that information about life expectancy would influence their medical decisions (CI 0.56–0.94; p<0.01). Conclusion: In a majority of cases oncologists actually told patients that their cancer is not curable. Most patients, however, did not understand what was communicated. Patients’ understanding of prognosis is determined not only by what oncologists communicate, but also by patients’ desire for prognostic information. No significant financial relationships to disclose.
