This two-phase study aims to examine the current status of older adults with newly diagnosed locally advanced or advanced non-small cell lung cancer and their primary family caregivers, and to evaluate the effects of the Integrating Nurse-Led and Resource Utilization-Based Caregiver Support Model (ICSM). Phase I is a cross-sectional correlational study assessing distress, unmet care needs, resource awareness and utilization, social support, and health promotion practice. Phase II is a two-group randomized controlled trial comparing ICSM plus oncology case manager care with oncology case manager care and usual hospital care. The intervention includes nurse-led education and counseling, symptom management, emotional coping, problem-solving, social resource use, caregiving activity arrangement, and use of a web-based or LINE-based integrated resource system.
