Caregivers’ health impairment: The caregivers were able to state if they felt health-impaired themselves due to caregiving (yes) or not (no) (a) and could differ between physical (blue) and mental (yellow) symptoms (b). Three adjacent columns in (a) are assigned to each BI group (groups 1–4). The extent of the colored sections represents the percentage of caregivers. We observed a statistically significant increase in the incidence of physical and mental health impairment according to the BI group (BI group 4 (=BI score 100 points = full independence) to BI group 1 (=BI score 0–20 points = full dependence)) and thus decreasing autonomy of the patients. Abbreviations: BI = Barthel Index.
