SUPPORT+ Digital Self-Management and Clinical Support for Advanced Cancer

Patients with advanced cancer often experience substantial physical and psychological symptom burden that negatively affects health-related quality of life and may lead to avoidable emergency department visits and hospitalisations. Digital symptom monitoring tools may support earlier identification of symptom deterioration and timely intervention, but evidence in palliative care populations remains limited.

This multicentre, randomised controlled trial evaluated whether adding SUPPORT+, a mobile application for symptom monitoring with automated self-management guidance and nurse follow-up, to usual palliative care could improve patient-reported outcomes and healthcare utilisation among adults with advanced cancer.

Community-dwelling adults aged 18 years or older with advanced malignancy who had decided not to pursue further systemic anticancer treatment and were receiving follow-up at palliative care clinics in six public hospitals in Hong Kong were recruited. Eligible participants were required to own a smartphone, have adequate cognitive capacity to provide informed consent, be willing to receive application notifications, and report at least one symptom related to advanced cancer. Patients with an estimated life expectancy of less than three months or an Eastern Cooperative Oncology Group (ECOG) performance status greater than 3 were excluded. Caregivers were permitted to act as proxy users when participants were unable to use the application independently.

Participants were randomly assigned in a 1:1 ratio to either the intervention group (SUPPORT+ plus usual care) or the usual care group. Randomisation was stratified by age, chronic opioid use, and app user (patient or caregiver proxy). Clinicians providing routine palliative care were not informed of group allocation.

All participants received standard palliative care according to usual clinical practice. Participants in the intervention group additionally received full access to the SUPPORT+ mobile application for 18 weeks. Weekly notifications prompted symptom reporting using the Integrated Palliative Care Outcome Scale (IPOS). Following each submission, participants received automated symptom-specific self-management advice. Reports containing any severe symptom triggered real-time alerts to palliative care nurses, who contacted participants during office hours to provide clinical guidance, including medication advice, self-management strategies, expedited clinic review, or recommendations for urgent care when appropriate. Participants could also initiate nurse contact through the application during office hours.

Assessments were conducted at baseline, week 9, and week 18. The primary outcome was change in health-related quality of life measured using the EQ-5D-5L utility score. Secondary outcomes included self-rated health (EQ-VAS), self-efficacy for managing chronic disease, ECOG performance status, emergency department visits, hospitalisations, length of hospital stay, and completion of advance directives. Healthcare utilisation data were retrieved from electronic medical records.
