To offer advanced nursing care for people living with HIV, a participatory action research project was initiated that enabled constant learning and change at the levels of (a) the culture and organization of an outpatient department, (b) clinical leadership and interdisciplinary collaboration, and (c) development of new services. In this project, the development of the Advanced Nursing Practice (ANP) Team not only affected the practice of individual nurses with advanced degrees but also created a team of nurses educated at different levels. Through a systematic process, the nurses on the team became more educated and refined their clinical expertise. An essential aspect of the ANP Team was the specialization of each nurse in a self-selected topic within HIV/AIDS care. As members of the ANP Team, the nurses offer state-of-the-art nursing care including patient assessment, medication management and adherence support, symptom management, health maintenance and prevention, and family support for persons living with HIV.
