Specialised nursing tasks in cancer care and their effects.

Several reviews are available on the effects of specific nursing tasks in oncology care. However, a synthesis across cancer entities and stages is lacking. To synthesise the results of reviews assessing the scope and effectiveness of tasks of nurses specifically qualified in cancer care. We conducted an Umbrella Review based on systematic searches in six databases and a search for grey literature following a priori-defined inclusion criteria. Further steps: standardised data extraction and quality assessment, determination of the degree of overlap, and structured narrative summary on outcome measures of health-related quality of life, symptom burden, utilisation of care services/resources, and patient satisfaction. All reviews were categorised according to the EONS Cancer Nursing Education Framework and the Omaha System Intervention Scheme. After screening 2,657 references, 11 reviews (10 high quality) for a total of 148 studies were included. Specially qualified nurses and advanced practice nurses take on a variety of tasks in the disease process, especially related to education, counselling, and case management. Effects on outcome measures are mixed, with increased indications of reduced symptom burden. Specially qualified nurses with expanded roles have the potential to contribute to improved oncology care. This emphasises the importance of appropriate task profiles and qualification programs. More well-reported studies based on theoretical framework models are needed.
