The health problems of hemodialysis patient are complex, involving physical, mental and social aspects. Those with chronic conditions must be able to resolve disease and treatment problems on their own expectation in order to maintain life quality. This case report describes how the authors applied the ADOPT (Attitude, Definition, Open mind, Planning, Try it out) problem-solving training model to care for a hemodialysis patient with poor interdialytic weight gain (IDWG) control. Nursing care was provided to this patient from November 3rd to December 8th, 2008. This case demonstrated ADOPT model efficacy at improving the patient's problem solving abilities in various daily life situations. The authors hope this theory-based intervention can help establish an innovative and effective care model for patients with chronic conditions.
