Abstract: A qualitative framework was used to explore the nature and the quality of interactions between sole on-call primary health care rural nurses and secondary care doctors. This study is framed as investigating a specific component of rural nursing practice and as being representative of the primary-secondary care interface. The primary-secondary care interface is crucial for the delivery of patient-centered care, and there is an increased focus on preventive primary health care. The New Zealand government sees the repositioning of professional roles and increasing emphasis on collaboration as an opportunity to re-define and address the current constraints to nursing practice. This has resulted in tensions between the medical and nursing professions. These tensions are not new, with the relationship sometimes marred by conflict which has been attributed to historical medical dominance and nursing deference. This study explores some specific areas which affect collaboration and makes recommendations at the national, regional and individual level to address them.
