Ming Lun Cross-hospital Nutritional Social Support Program has signed contracts with 7-8 hospitals in the south-central region since 2012 to provide 7 nutritional supplements and social support, emotional support and health education awareness messages for patients with head and neck cancer during treatment. This study used 1028 complete case service records from 2014 to 2016, 3 program work discussion meeting records and 23 mid-term checklists and other documents to analyze the implementation process of contract hospitals by content analysis method and extract cross-institutional cooperation service experience; In addition, the seven staff members were interviewed in a semi-structured manner to understand their experience and suggestions. The study found that the implementation process was affected by the stability of the staff of each hospital, the timing of the supply of nutrients and the way of execution due to their actual conditions. In addition, the staff shared the program to increase the interaction between the staff and the patient, which formed a deep trust relationship, and facilitated the resource transmission and strengthened its connection with the resources of the head and neck cancer patients, and also played a closer role in cooperation with the medical team. The research team's plan can bring benefits to other social welfare organizations and civil organizations, and encourage workers to bring more services to the case.
