Stroke-related secondary complications increase the length of hospital stay, negatively affect the functional expectation in the rehabilitation process and increase repeated hospital admissions. For these reasons, complications secondary to stroke are associated with mortality and increased economic burden. Prevention of secondary complications is important. Increasing the level of knowledge and awareness of caregivers, who are constantly with the patient, about secondary complications is effective in preventing secondary complications. The aim of this study was to evaluate the level of awareness of caregivers about secondary complications related to stroke and the effect of rehabilitation process. There is no study or scale evaluating the level of awareness of secondary complications related to stroke in the literature.
