This study focuses on patients with non-muscle-invasive bladder cancer who receive intravesical perfusion therapy. Outpatient perfusion treatment is usually short-term and procedure-oriented, so patients often lack continuous, comprehensive support after returning home, and may face physical discomfort, psychological stress and unmet self-management needs during home recovery. This study aims to identify real-world difficulties and needs of patients in home-based recovery, construct a personalized home supportive care program covering physical symptom relief, psychological support and disease management education, and test its preliminary application effect. It is expected to reduce patients' treatment-related discomfort, improve treatment adherence, and enhance their quality of life.
