Information needs of early-stage prostate cancer patients: within- and between-group agreement of patients and health professionals

Purpose The aims of this study were to analyze agreement on information needs within a group of early-state prostate cancer patients and to compare information preferences of patients with the view of health-care professionals about patients’ needs. Methods Sample consists of patients ( n = 128) and six subgroups of health-care professionals (urologists, n = 32; nurses, n = 95; radiotherapy technologists (RTTs), n = 36; medical oncologists, n = 19; radiation oncologists, n = 12; general practitioners (GPs), n = 10). Information needs have been assessed with 92 questions concerning prostate cancer and its treatment. Respondents judged the importance of addressing each question. Within- and between-group agreements of patients and health-care professional groups were estimated with raw agreement indices as well as chance-corrected Kappa and Gwet’s AC1 measures. Finally, group-specific core items rated with high importance as well as high agreement were defined. Results Patients rated on average (median) half, i.e., 51 out 92 items as essential (interquartile range (IQR) = 36–66), 26 items as desired (IQR = 14–38), and 10 items as avoidable (IQR = 2–22). Within-group agreement on the presented information topics is modest for any participating group (AC1 patients = 0.319; AC1 professionals = 0.295–0.398). Agreement between patients and professionals is low too (AC1 = 0.282–0.329). Defining group-specific core sets of information topics results in 51 items being part of at least one core set. Concordance of the item core sets of patients and professionals is moderate with κ = 0.38–0.66, sensitivity of professionals’ core sets for patients’ preferences varies between 56 and 74 %. Conclusions Results emphasize the need for dialogue between doctor/professional and patient in identifying the information needed by individual patients and support the importance of shared decision making.
