Randomised controlled trial protocol (GRIP study): examining the effect of involvement of a general practitioner and home care oncology nurse after a cancer diagnosis on patient reported outcomes and healthcare utilization

BACKGROUND: Due to the ageing population and improving diagnostics and treatments, the number of cancer patients and cancer survivors is increasing. Policymakers, patients and professionals advocate a transfer of (part of) cancer care from the hospital environment to the primary care setting, as this could stimulate personalized and integrated care, increase cost-effectiveness and would better meet the patients’ needs and expectations. The effects of structured active follow-up from primary care after cancer diagnosis have not been studied yet. Therefore the GRIP study aims to assess the effects of structured follow-up after a cancer diagnosis, by a primary care team including a general practitioner (GP) and a home care oncology nurse (HON), on satisfaction and healthcare utilization of patients treated with curative intent. METHODS: We will conduct a multicentre, two-arm randomised controlled trial in The Netherlands. We plan to include 150 patients who will be treated with curative intent for either breast, lung, colorectal, gynaecologic cancer, or melanoma. Further inclusion criteria are: age 18 years and older, able to answer questionnaires in Dutch, GP agrees to participate and the possibility to include the patient before the start of treatment. All patients receive care as usual. The intervention arm will receive additional structured follow-up consisting of a GP consultation before onset of treatment to empower the patient for shared decision making with the specialist and a minimum of three contacts with the HON during and after treatment. Primary outcomes are: patient satisfaction with care at the level of specialist, GP and nurse and healthcare utilization. Secondary outcomes include: quality of life, employment status, patient empowerment, shared decision making, mental health and satisfaction with given information. Repeated questionnaires, filled in by the participants, will be assessed within the 1-year study period. DISCUSSION: This randomised controlled trial will evaluate the effects of structured follow-up after a cancer diagnosis by a primary care team including a GP and HON, for patients undergoing treatment with curative intent. Results from the present study may provide the evidence needed to optimally rearrange responsibilities in cancer care delivery and consequently improve cancer care and patient related outcomes.
