Assessment of the Feasibility of a Systematic Multidimensional Evaluation of the Outcome of Head Injury Patients and Their Families. A Single-center Pilot Cohort With Repeated Longitudinal Follow-up

The study aims to assess the feasibility of collecting multidimensional outcomes of patients with traumatic brain injury, taking into account the patient-relative dyad. However, this multidimensional assessment may pose enormous problems of feasibility during the follow-up: loss of the patient's pathway, moderate acceptance by patients and relatives, difficulties of remote assessment sometimes carried out several times.... All these factors can affect the methodological quality of the evaluation of patient outcomes, with measurement and reporting biases influencing the results of biomedical trials. In order to improve the quality of clinical research in this field, it is therefore essential to fully appreciate the factors that facilitate or, on the contrary, hinder high-quality longitudinal follow-up.
