Background: Family caregivers are often the first line of support for people requiring care; although they may personally stand to benefit, these activities substantially increase the risk of physical and emotional stress. General practitioners (GPs) may provide important support and stabilisation, but need to adjust to the needs and expectations of this group in order to do so. Objectives: The aim of the study was to compare the needs of family caregivers from GPs to the support they actually experience. Additional aims included determining the main factors affecting satisfaction amongst family caregivers with support from GPs. The results were used to develop possible approaches towards optimisation within the purview of general medical practice. Methods: Between January and July 2020, 612 people supporting or caring for a family member responded to an online survey posted in seventeen internet forums focused on family caregivers. In addition to the descriptive analysis, a t-test with independent samples was used to identify significant differences between two groups. We also used binary logistic regression analysis to identify indications of potentially influential factors regarding the experienced support from GPs. Results: Around three out of every four respondents (72%) consulted GPs in care matters. The respondents gave positive responses on their GP's knowledge of the care situation (71%), approachability in various issues connecting with care and service towards the caregiver (82%). GPs' efforts in meeting the needs and requirements of the care recipient were also rated positively (82%). Weaknesses in support from GPs mainly involved the lack of information on advice and assistance services (55%) as well as frequently not identifying or involving caregivers as such soon enough (42%). Results from regression analysis show that the last two aspects play a major role in subjective satisfaction amongst family caregivers with support from GPs. Conclusions: We recommend that GPs undergo further training to reinforce awareness that the care triad of needs, requirements and stresses amongst family caregivers also plays a vital role in care outcomes. With this in mind, general practice staff should adopt a pre-emptive strategy towards approaching family members about potential issues and informing them about existing assistance and support services.
