Determinants of information security policy compliance: integrating task-technology fit and threat avoidance appraisals in the digital workplace.

Acute leukemia (AL) is a heterogeneous group of hematologic malignancies characterized by rapid proliferation of immature hematopoietic cells (). Although induction chemotherapy can achieve complete remission in a substantial proportion of patients, the disease course is often protracted, requiring repeated hospitalizations for consolidation or maintenance therapy, as well as intensive supportive care (, ). Between hospital stays, patients face numerous challenges including myelosuppression-related infections, bleeding tendencies, chemotherapy-induced nausea and vomiting, nutritional deterioration, and psychological distress (). Effective self-management—monitoring vital signs, recognizing early signs of infection, adhering to complex medication schedules—is crucial for reducing adverse events (). Conventional continuous care models rely on telephone follow-up, outpatient visits, and printed materials. These approaches have inherent limitations: intermittent contact may miss early warning signs, and one-way communication does not allow real-time problem-solving, leaving patients feeling isolated (). Moreover, AL patients can deteriorate rapidly (e.g., febrile neutropenia), and delayed recognition may lead to severe sepsis or death (). Mobile health (mHealth) technologies can bridge this post-discharge gap (). Using smartphones and WeChat mini-programs, providers can deliver educational content, collect patient-reported data daily, send medication reminders, and enable two-way communication (). While mHealth interventions have improved self-efficacy and QoL in oncology (), evidence specific to AL is limited, and few randomized trials have simultaneously measured multiple clinical endpoints. Therefore, this study aimed to evaluate the effects of an mHealth platform-based continuous care program on self-management behaviors, QoL, medication adherence, anxiety/depression, daytime sleepiness, cancer-related fatigue, complications, and rehospitalization in AL patients, compared with routine care.
