Background: Patients with short-bowel syndrome and intestinal failure (SBS-IF) require parenteral support (PS) and may need long-term home-care support. This survey assessed the impact of care provision on adult caregivers of adult patients receiving PS for SBS-IF. Methods: An online, cross-sectional survey of caregivers of adults with a self-reported physician diagnosis of SBS-IF was conducted in France, Germany, Italy, the UK, and USA. Impact on caregivers was evaluated using the 18-item Caregiver Strain Index (CSI), the Work Productivity and Activity Impairment Questionnaire: Specific Health Problem (WPAI:SHP), and self-reporting impact questionnaires. Results: Caregivers (N = 121; aged 51 ± 13.7 years; 59% women) provided assistance for a mean of 9.9 ± 12.53 years; 77% were providing care 7 days per week. Patients (51 ± 16.4 years; 56% women) of caregivers were typically family members: spouse/partner (61%), adult son/daughter (19%), or parent (10%). Caregivers reported experiencing some strain (CSI score 4 ± 3.4). Among 71 of 73 employed caregivers, the WPAI:SHP assessment showed that caregivers missed 7% ± 12.7% of work hours in the preceding week and were present but not productive at work 37% ± 23.1% of the time; 28% of caregivers reported a reduced number of working hours because of caregiving. Many caregivers reported limitations in recreational activities (53%), and ≥30% had difficulty spending time with family and friends. Caregivers (87%) also reported worrying about the patient's health. Conclusions: Caregivers of adult patients with SBS-IF experience negative daily personal impacts and loss of productivity arising from their caregiving responsibilities.
