The members of the family are generally those who assume the care of stroke patients. This study has aimed to know the overload of informal caregivers of stroke patients and to analyze the relationship between this overload and the functional performance of the patients.
All of the patients who were admitted in our hospital to receive rehabilitation treatment after stroke and who were discharged from July 2007 to February 2008 were included in the study. The caregiver overload was assessed on the Zarit Overload Scale and the functional performance of the patient was evaluated with the Functional Independence Measure (FIM) value at the time of hospital discharge.
The average time from hospital admission to when the surveys were administered was 15 months (SD 2.07). A total of 78 % of the 114 caregivers who participated in the study were women, with a mean age of 61 years. The spouse was the relative most involved as caregiver (69.2 % ), followed by the children (20.1 % ). We received the Zarit survey from 69 caregivers, with a mean score of 33.62 (SD 17.23). There was no correlation between the FIM values and the Zarit Scale (p=0.83).
Most of the stroke patients live at home, attended by a relative. The usual caregiver is a woman, who suffers a great overload caused by the care she gives. The degree of disability of the patient does not determine, by itself, the overload experienced by the caregiver.
