Background: Relatives of stroke patients should be an integral part of the continuum of rehabilitation services. Objectives: The objective was to describe their perception of the quality of the services they received in the context of early supported discharged (ESD), in- and out-patient rehabilitation services. Methods: Descriptive study using the Quality of Services Questionnaire for Relatives post-stroke (QSQR) completed online by relatives after the patient's discharge. It consists of 22 statements with respect to three subscales: 1) the training/instructions, 2) the information provision and 3) the organizational process of the service offer. Space is allowed for free comments and two open-ended questions. Quantitative data were analyzed descriptively, and we used a content analysis for qualitative data. Results: One-third (30/90; 33.3%) of the sample are composed of relatives aged 55 and under, with a majority (81%) of women and 51.3% of spouses. The training/instructions and information provision were perceived positively with a mean % agreement at 85.0 ± 29.6 and 84.8 ± 22.4, respectively. The mean % agreement was 91.4 ± 17.8 for the organizational process subscale. A significantly higher score (p = 0,03; Kruskal Wallis test) was found for out-patient services (n = 20) as compared to ESD (n = 29) or in-patient rehabilitation (n = 41). Qualitatively, a lack of involvement of relatives was mentioned as well as a lack of personalized information about stroke and its consequences and provision of resources available. However, communication between professionals, their availability, and their professionalism were appreciated. Conclusions: Despite quantitative high scores, qualitative data allowed the identification of concrete avenues for improvement to truly and systematically include relatives in stroke rehabilitation.
