A fluctuating intensity of care: A qualitative study on the experiences of informal caregivers of patients with critical limb-threatening ischemia

Informal caregivers play a significant role in providing care for older, often vulnerable, patients, and supporting them as they live with chronic diseases. Due to the rising prevalence of older vascular patients and their use of healthcare, the role of their informal caregivers will become more important. However, little is known about the experiences of informal caregivers of patients with critical limb-threatening ischemia and the impact of informal care on different aspects of these caregivers' lives. In addition, literature does not describe the burden this role brings with it, or lack thereof. Therefore a qualitative study using a phenomenological approach, specifically interpretive phenomenological analysis, was used to gain insight into the experiences of the primary informal caregivers of patients with chronic limb-threatening ischemia. Data were collected via semi-structured interviews and focus groups discussions. Fifteen primary informal caregivers of patients with critical limb-threatening ischemia under the care of the vascular surgeon at a tertiary teaching hospital in the Netherlands were included. Data analysis yielded three themes: the perceived identity of this group of caregivers; the varying intensity of informal care; and the collaboration between informal carers, their care recipients and the professional care provider within the vascular surgery department. In contrast to carers of other chronic diseases, the shifting intensity of care that informal caregivers of critical limb-threatening ischemia patients experience seems to prevent long-term overload. Adapting to that fluctuating situation requires flexibility from healthcare providers within the vascular surgery department. In addition, professionals need to involve informal caregivers in the patient's decision-making process and recognize their role in that process.
