Information Needs and Attributes of Breast Cancer Radiotherapy Patients Based on the Kano Model: A Cross‐Sectional Study

ABSTRACT Background Identifying the core information needs of breast cancer radiotherapy patients serves as the foundation for delivering targeted information services. The Kano model, a qualitative tool for classifying service needs, is increasingly being employed to prioritise patient needs and enhance healthcare quality. Objective This study aims to examine the informational needs of breast cancer patients undergoing radiotherapy using the Kano model as the analytical framework. Methods Between October 2024 and February 2025, 260 patients with breast cancer undergoing radiotherapy were recruited as study participants. A cross‐sectional survey was conducted using the Information Needs Questionnaire. Kano analysis was applied to identify and assess the information needs of these patients. This study adhered to the STROBE guidelines. Results Among the 36 items analysed, 15 items (41.7%) were classified as one‐dimensional attributes, primarily related to adverse reaction identification and self‐management information. 11 items (30.5%) were identified as attractive attributes, mainly concerning the impact of radiation therapy and social–emotional needs five items (13.9%) were must‐be attributes, focusing on basic radiotherapy information. Five items (13.9%) were indifference attributes, including the impact of radiotherapy on breast reconstruction, and guidance on image‐related concerns during radiotherapy. The quadrant chart findings revealed that 15 needs were predominant in Area I, five in Improving Area II, five in Secondary Improving Area III and 11 in Reserving Area IV. Conclusion The information needs of breast cancer radiotherapy patients are diverse. Kano model analysis aids medical staff in developing health guidance and meeting patients' informational needs. Relevance to Clinical Practice Understanding the differentiated informational needs of patients with breast cancer undergoing radiotherapy provides valuable insights for developing targeted educational interventions, ultimately improving patient engagement and outcomes.
