Care provided by an advanced practice nurse: Experiences of patients with sarcoma and family members. A qualitative study; Abstract.; Background:; Sarcomas are a rare, heterogeneous group of malignant tumors with different trajectories, which cause significant burden to patients and families. Due to the complex nature of treatment, an interprofessional team at the sarcoma center of a Swiss university hospital provides care to affected individuals. This interprofessional team includes an advanced practice nurse (APN) who cares for patients and family members throughout the trajectory of the disease. To date, there are limited descriptions within literature of APN care from the perspective of patients with sarcoma and their family members.; Aim:; To investigate how patients with sarcoma and their family members experienced APN care.; Methods:; The study was guided by the qualitative research methodology "Interpretive Description". Individual interviews with seven patients and five family members were conducted and analyzed in an iterative process.; Results:; For patients and family members, the time from diagnosis to therapy and follow-up was very stressful. They experienced the APN's care during this time as a great support and described her as a compassionate, trustworthy and continuous contact person who expertly provided information and advice while acting as a coordinator.; Conclusions:; Patients with sarcoma and their family members require continuous contact with a person who is compassionate, while also professional, confident and competent. Providing APN care can meet all of these essential requirements.
