Self-management has become increasingly important with the growing population living with chronic conditions. Self-Management Support (SMS) provided in healthcare systems is essential for its success. While prior research mainly focuses on Western countries, this paper presents a study of SMS practices for osteoporosis management as part of a Whole Course Management (WCM) program recently implemented in the healthcare system in China, which features a new role called case manager in the hospital dedicated to SMS and related coordination. Based on interviews with 22 participants, including one case manager, two physicians, three nurses, seven patients, and nine caregivers, we highlight the importance of the role of case manager in promoting awareness of osteoporosis and self-management, integrated care coordination, and emotional support. At the same time, it also reveals challenges and promising directions to make SMS more effective, mainly in terms of self-management education, active patient involvement, and coordination among the care network. We ended by reflecting on our findings and discussing implications for SMS and the design of ICTs.
