The paper introduced the present full-time practice of medical social workers in China, with in-depth analysis of the roadblocks encountered. The problems include but are not limited to multiple stakeholders without a healthy resources relationship network, lack of powerful government support in policy and resource orientation, absence of drivers for hospitals to deliver social service, immature social organizations, and poor capacity to link resources. Based on such, the authors explored the establishment of a development model for full-time medical social workers on a multiple cooperation platform, in such perspectives as the government, social worker organizations, hospitals, and third-party performance appraisal.
