Background. Informal care provided by family caregivers to old persons is associated with a high risk of burden and poor health status. This study aimed to analyze the impact of Personalized Social Support (PSS) for non-dependent old persons living in the community on caregiver burden, satisfaction, and frailty. Methods. This non-interventional longitudinal study was performed in the southeast of France: old persons asking for PSS (>70 years of age, with no disability and no severe chronic disease, living at home) and their caregivers were included with a 6-month follow-up. Eligible dyads were visited at home by social workers. Caregiver burden was assessed with Mini-Zarit and frailty status with FiND (Frail Non-Disabled).Results. 876 dyads were eligible for PSS. Old persons were 82.2 ± 5.8 years old and 77.6% were women. Most caregivers were women (64.5%). Most caregivers were the children of the old person (61%), the rest were mostly spouses. Nearly 64% of old persons were frail and 38% were highly dependent. Follow-up was conducted for 686 dyads (78.3%). Of these, only 569 had PSS. The PSS was mainly for housework and meal preparation. At the time of follow-up, 53% of the caregivers for whom the old person had PSS had less difficulty helping their old person. Two-thirds (61.5%) of caregivers were fully satisfied with the PSS. Whether or not they had received the PSS, 73% of caregivers had reduced burden at 6 months, only 6% still had a high burden, 17% were less frail, and 18% felt healthier than at the time of inclusion.Conclusions. Our study highlights that non-dependent old person’s caregivers also experience burden. Implementing social support for activities of daily living had a major impact on their burden but not on their level of frailty. This means that the determinants of caregiver frailty are more complex and further studies are needed.

Background. Informal care provided by family caregivers in old persons is associated to a high risk of burden and poor health status. This study aimed to analyze the impact of a Personalized Social Support (PSS) attributed to non-dependent old persons living in the community on caregiver burden, satisfaction and frailty. Methods. This non-interventional longitudinal study was performed in the south East area of in France: old persons asking for a PSS (>70 years old, with no disability and no severe chronic disease, living at home) and their caregiver were included with a 6-months follow up. Dyads were visited at home by social workers. Caregivers Burden has been assessed with Mini-Zarit and frailty status with FiND (Frail Non-Disable). Results. 876 dyads (old persons: female 77.6%, aged 82.2 ± 5.8 years old; caregivers: 64.5% female, 29% spouse, 61% children; 64% with frailty and 38% with high burden (high burden being significantly associated with frailty)) were eligible for a PSS. The follow-up was possible completed for 686 of them (78.3%). Among them, 569 PSS were financed, mainly: housekeeping and meal preparation. At follow-up, 53% of caregivers who had PSS experienced fewer difficulties in caring for their old person. Whether or not they received the PSS, 73% of the caregiver had a lower burden level, only 6% had a persistent high burden; 17% of them were less frail and 18% felt their health status was better than at the time of inclusion. 61,5% of caregivers who had PSS were totally satisfied. Conclusions. Our study highlight that the burden occurs also in non-dependent old person’s caregivers. Social support implementation for activity of daily living had a major impact on the burden but not on the caregiver frailty, which means that determinants of caregiver’s frailty are more complex and further studies are needed.
