Stroke is the second leading cause of death and disability in Brazil, being more prevalent in the elderly. This event can cause a loss of functional capacity for the patient and the consequent need for a caregiver who needs to receive guidance on how to perform care, especially since the transition of care from the hospital to the home is one of the most critical periods, in which the family requires greater support. Thus, a structured intervention for training the caregiver, starting at hospital admission, with follow-up after discharge, is considered a requirement of good practices. With the COVID-19 pandemic, virtual strategies to support caregivers have been more used. The aim of this study is to analyze the effectiveness of a virtual educational intervention on the ability and performance of family caregivers to care for elderly people with stroke sequelae. This is a pragmatic randomized study with caregivers of elderly patients hospitalized at Hospital de Clínicas de Porto Alegre for stroke. Participants will be recruited at the Emergency Service, the Stroke Special Care Unit and other clinical inpatient units. Family caregivers over the age of 18 with internet and telephone access will be included. Participants will be randomized into an intervention group (29) and a control group (29), using a list generated on the randomization.com page. The intervention for the IG will be carried out by nurses and will consist of a virtual educational action through a massive, open and online course (MOOC), in addition to telephone contacts made in: seven days, 30 days, 60 days and 80 days after discharge . A hotline will also be available for participants to contact if they have any questions. The intervention aims to equip the family caregiver to assist the elderly person at home in care, such as hygiene, feeding, positioning and transfer, based on the previously validated Guidance Manual for Family Caregivers of Elderly People with Stroke. Identification, sociodemographic and health data of the elderly and their caregivers will be collected. The Capacity Scale for Informal Caregivers of Elderly Stroke Patients (ECCIID-AVC), the Nursing Outcomes Classification (NOC) through selected results and indicators and the Caregiver Burden Scale (CBS) will be applied to the caregiver. The Functional Independence Measure (MIF) and data on readmissions will be applied to the elderly, all scales being validated for use in Brazil. Three months after hospital discharge (90 days), caregivers and elderly people will be reassessed with the same instruments. Control group participants will receive initial and final assessments. For data analysis, the Statistical Package for the Social Sciences (SPSS) version 21.0 will be used. The intention-to-treat technique will be used and continuous variables will be described as mean and standard deviation, or median and interquartile range. For categorical variables, absolute numbers and relative frequencies will be used. According to the data distribution, the basal characteristics of the groups will be compared by Student's t test and Mann-Whitney. To analyze the effectiveness of the intervention on the outcomes, the difference between baseline and final scores will be evaluated by the paired Student's t test, with a confidence interval of 95%, and will be considered a significant value p\<0.05. The project will be submitted to the HCPA Research Ethics Committee.
