After receiving chemotherapy, targeted therapy, immunotherapy and other drug treatments, tumor patients often experience various adverse reactions such as bone marrow suppression, diarrhea, pneumonia, etc. However, due to the limited capacity of the hospital, if patients who are discharged home cannot timely detect and deal with severe drug adverse reactions, it will cause harm to their bodies and even threaten their life safety. With the rapid development of network communication, many foreign institutions have tried to develop ePRO software based on patient symptom reports. This type of software is used to monitor drug adverse reactions and provide timely feedback to the attending physician for medical intervention. Existing studies have shown that the application of this type of ePRO software significantly reduces the severity of drug adverse reactions on patients and significantly prolongs survival time. In this study, the investigators plan to collaborate with Shenzhen 123 Digital Medical Group Co., Ltd. to design and develop a tumor ePRO software that allows outpatient treatment period patients who are discharged home to regularly self-assess the severity of drug adverse reactions and automatically feed back the scoring results to the department's monitoring center. Doctors will make timely diagnosis and treatment based on each patient's score results in order to maximize patient safety after treatment at home. The results of this study will provide better follow-up care for tumor patients who are discharged home after anti-tumor treatment by significantly improving the safety of outpatient treatment period patients with tumors and thereby improving patient survival time and quality.
