LOG-I - Impact Study of LOG-AFTER Software on Long-term Monitoring of Former Patients (LOG-I - LOG-Impact Study)

Childhood cancer survivors represent a high-risk population that requires risk-based follow-up. Follow-up recommendations have been harmonized. Education and information practices regarding follow-up recommendations should be personalized, to ensure understanding by all survivors, including those with neurocognitive disorders. Individualized follow-up is necessary to detect complications that may increase morbidity and decrease quality of life, or even increase the risk of early mortality.

In France, the LOG-AFTER software was developed in 2017 by university hospital of Angers and Epiconcept (approved health data host). The main differences with the European procedure concern radiotherapy information, the link with the General practitioner (GP), and the possible addition of information and/or access to therapeutic education in a video format. Indeed, there is the possibility of creating an GP account allowing to receive notifications concerning the follow-up of his patient to be scheduled, to have access to his file summary and his personalized follow-up plan, various information and blank prescription models. LOG-I is a study of the impact of the LOG-AFTER software for the "patient/GP" couple on adherence to follow-up recommendations. LOG-I is interested in all former patients with at least 3 recommendations in their personalized follow-up plan, taking into account the specific population of patients cured of a brain tumor.

Recruitment as long-term follow-up consultations progress. After checking the selection criteria, the investigator informs the patient of the study or the parents of the minor child orally and in writing with delivery of the information letter and answers any questions. If the patient, or their parents for minor patients, agrees to participate, the informed consent form is signed in 2 copies by the different parties. The date of the information and the date of signature of the consent are documented in the patient's source file. Following the inclusion of the patient, randomization is carried out (WITH and WITHOUT use of the LOG-AFTER software).

During this visit, for patients randomized in the LOG-AFTER software, an account is created within 5 days following the consultation.

For all patients (randomized with or without access to LOG-AFTER) the following data are collected in LOG-AFTER:

* Health data: type of first cancer, start and end dates of treatment
* Patient data required for research: gender, month and year of birth, after-effects, psychosocial data (level of education, life as a couple and children if concerned, profession if concerned).

The module to help create the Personalized After-Cancer Plan (PPAC) can be used for everyone and the PPAC is recorded in LOG-AFTER.

The PAM-13 questionnary is completed by the patient.

Contact with the GP : Following the patient's inclusion and randomization in the "WITH access to LOG-after" group, his GP is informed by mail and telephone call. He receives his codes by email via the software.

Patient follow-up : It is organized according to the habits of the specialist and/or his general practitioner.

For patients randomized with access to LOG-AFTER, patients are advised to report the completion of the examinations (date and overall conclusion of the examination), which allows the software to function properly. The GP is also advised to report any consultations his patient has had with him and to update the date of the examinations if his patient has not done so.

Visit at 36 months (+/- 3 months) • For patients randomized to the "LOG-AFTER" group: The patient is contacted 3 years after inclusion by the clinical research associate or reviewed in consultation by the doctor. The follow-up data according to the PPAC are updated if necessary in LOG-AFTER. If necessary, the PPAC can be updated and modified.

The satisfaction questionnaries (Software and Care Pathway) are given (paper format or via the software) to patients and GP. The PAM-13 questionnary is completed again by the patient. A telephone call (doctor or research associate) is made 2 weeks later if not completed with a proposal to do it by telephone.

• For patients randomized to the "usual care" group: The patient is contacted 3 years after inclusion by the clinical research associate or reviewed in consultation by the doctor. The follow-up data according to the PPAC are collected in LOG-AFTER. A satisfaction questionnary on the care pathway (paper format or via software) is sent to patients and GP. The PAM-13 questionnaire is completed again by the patient. A telephone call (doctor or research associate) is made 2 weeks later if not completed with a proposal to do it by telephone.

At the end, an account is created for the patient/GP couple if the patient wishes.
