Expert and Patient Evaluation of an Education Tool for Breast Cancer Patients on Endocrine Therapy: Assessment of Usability, Knowledge and Medication Beliefs
摘要
Non-adherence to endocrine therapy was associated with insufficient knowledge and poor beliefs towards treatment. A culturally-appropriate education tool may be needed to improve patient care. This study aimed to evaluate a newly developed education tool, with two phases of evaluation involving experts and potential users consisting of breast cancer patients on endocrine therapy. Expert evaluation involved assessment by a multi-disciplinary panel (n = 10) using three tools to assess different aspects of quality: Ensuring Quality Information for Patients (EQIP); Patient Education Materials Assessment Tool (PEMAT), which consists of Understandability and Actionability scales; and Suitability Assessment of Materials (SAM). The mean scores for EQIP (90.3%), PEMAT (Understandability: 98.2%; Actionability: 96.3%) and SAM (93.4%) revealed that the education tool exhibited good quality. User-based evaluation utilised pre- and post-questionnaires to evaluate user satisfaction via Consumer Information Rating Form (CIRF) and to evaluate the effects of the education tool on knowledge as well as beliefs, assessed using Beliefs about Medicines Questionnaire (BMQ). Patients were recruited from a university hospital and a national cancer institute. Results from CIRF indicated that the participants (n = 62) were satisfied with the comprehensibility, utility and design quality of the education tool. There was a significant improvement for knowledge (1.89 vs. 3.39, p < 0.01) and BMQ-General scores: General-Harm (2.24 vs. 1.91, p < 0.01) and General-Overuse (2.81 vs. 2.44, p < 0.01) after patients were introduced to the education tool. The findings indicated that the education tool may help to improve education for breast cancer patients on endocrine therapy.
