This is a stepped wedge of cross-over type. Patients included at each step are different individuals. The first step is a reference measurement where none of the clusters will implement the intervention. The investigating sites will be randomly drawn to determine the order in which they will implement the intervention, by steps of two months. A total of 10 patients by step are to be included in each center; these 10 patients must be regularly included along the 2-month period of each step. If 10 patients are already included before the end of the 2 months' step period, the center has to stop the inclusions till the beginning of the subsequent step. If a center, near to the end of a step, is far from reaching of the 10 patients' inclusion, it must increase the speed of its inclusions to be as close as possible of 10 patients included at the end of the step. In each center, patient sample has to be representative of type of cancer managed in the center, along the trial duration. The repartition of cancer types must be homogeneous along the steps and during the trial duration.~All participating investigating sites will have study collaborators in charge of organizing intervention implementation and data collection. The intervention will be prepared prior to the start of the trial, so that each investigating site can implement it as defined by the randomisation. Each center engaged to participate needs to participate till the end of the trial. A center commitment to participate will be requested before each center involvement to avoid center withdrawal after the start of the trial. Quantitative data regarding the HolisTM GV home app usage will be collected at each step and in each cluster by study collaborators, from the beginning of GERONTE system implementation. Care outcome data (Quality of life, anxiety, autonomy, additional hospitalisation, mortality...) will be collected by local referents at 3, 6, 9 and 12 months after inclusion in GERONTE. The data necessary to calculate the real cost of the intervention, of its implementation and of resource use data of patient management will be continuously collected during follow-up. GERONTE patient-centered system implementation and usage will be collected by the local referents in each center. Qualitative analysis will be performed in each center at GERONTE system implementation and during follow-up.
The primary objective of GERONTE STUDY is to evaluate the effectiveness of the GERONTE, ICT-based, integrated care pathway to improve patient 6-month quality of life, in France.~Study design is a stepped wedge randomised controlled trial. Clusters will be participating hospitals, comprising eight investigating sites in total (Figure 2).~This is a stepped wedge of cross-over type. Patients included at each step are different individuals. The first step is a reference measurement where none of the clusters will implement the intervention. The investigating sites will be randomly drawn to determine the order in which they will implement the intervention, by steps of two months.~The primary endpoint is the Quality of Life assessed by the EORTC QLQ-C30 (version 3.0) questionnaire at 6 months after GERONTE implementation. It has 3 sub-scores that will be analysed independently, with alpha risk adjustment.
