Rationale: Approximately 60% of patients with ovarian cancer have advanced stage disease at diagnosis, and thus aggressive surgical procedures are often medically necessary. Recent evidence suggests that nearly one in five patients hospitalized for ovarian cancer surgery will be readmitted within 30 days of discharge. Patients readmitted within 30 days have a 50% increase in one-year mortality rates and significantly increased costs of care. In addition, many of the conditions and complications that led to readmission could potentially have been avoided with more intensive post-surgical follow-up care. Mobile health technologies can effectively and efficiently connect patients with their healthcare team and have been shown to improve treatment adherence and reduce avoidable ER visits and hospitalizations.
