Contact nursing services have been implemented in Swedish cancer care to increase healthcare quality. Too little is known about the content and quality of these services and the organizational prerequisites provided to contact nurses. The aim of this study was to explore contact nurses’ perceptions of their services and organizational prerequisites, as well as the connection between organizational prerequisites and moral stress. A cross-sectional survey was utilized consisting of a study-specific questionnaire and a select part of the Stress of Conscience Questionnaire. The study is reported in accordance with STROBE guidelines for cross-sectional studies. The results showed that contact nursing service content varied across settings and that 84% of contact nurses have what was categorized as satisfactory or moderately satisfactory self-reported organizational prerequisites. Perceived moral stress differed between contact nurses depending on organizational prerequisites. The variability of both services and prerequisites can be described as inequities in care and complicates evaluation and comparison.
