Evaluation and Implementation Preparation of a Proactive Palliative Care Model (ENABLE-SG)

The current interdisciplinary specialist palliative care model focuses on supporting patients with advanced cancer who have complex problems in the last weeks of life. Consequently, palliative care is often provided late and in response to uncontrolled symptoms during crises. Palliative care models should shift from this reactionary illness-stress paradigm to a proactive health-wellness approach that is integrated early in the patient's disease trajectory. A proactive early palliative care telehealth model, ENABLE (Educate, Nurture, Advise, Before Life Ends), was developed in the U.S. to coach patients with advanced cancers and their family caregivers on how to cope effectively with serious illness. By empowering individuals early before acute distress and symptoms occur, patients and families can better mitigate and avoid crises. Building on positive health outcomes demonstrated by the ENABLE model in the U.S., the study team has successfully pilot-tested a culturally adapted ENABLE-SG model in Singapore. This study seeks to test the effectiveness of this ENABLE-SG model among patients with recently diagnosed advanced cancer and their caregivers while simultaneously collecting data on real-world implementation.

To evaluate the effectiveness of the ENABLE-SG model, we will conduct a randomized wait-list controlled trial comparing clinical outcomes at 6 months between patients and caregivers receiving early ENABLE-SG and their wait-listed counterparts receiving usual care. Eligible patients and their caregivers will be randomly assigned at baseline to receive ENABLE-SG either immediately or after a 6-month waiting period. To evaluate ways to improve implementation, the Consolidated Framework for Implementation Research (CFIR) will be used to systematically identify processes that influence implementation outcomes. The specific aims and hypotheses of this study are: 1. Assess the effectiveness of ENABLE-SG among patients with advanced cancer. We hypothesize that at 6 months, compared to usual care, patients who received ENABLE-SG will have better health-related quality of life (QoL), mood, health status, coping strategies, lesser palliative care concerns, lesser acute healthcare utilisation, and smaller hospital bill size. At 12 months, compared to wait-list control group, early ENABLE-SG recipients will have better primary and secondary outcomes. 2. Assess the effectiveness of ENABLE-SG among caregivers of patients with advanced cancer. We hypothesize that at 6 months, compared to usual care, caregivers who received ENABLE-SG will have better caregiver health-related QoL, mood, coping strategies, satisfaction with care, and lower caregiving costs. At 12 months, compared to wait-list control group, early ENABLE-SG recipients will have better primary and secondary outcomes. 3. Assess ways to improve ENABLE-SG implementation in the real-world context.
