Author(s) (Year), Country | Methodology | Participants Study Context | Identified Needs | Main Conclusions |
---|---|---|---|---|
Costa et al. (2021) [28], Portugal | Longitudinal Study (Quantitative) | 110 family caregivers of people with diabetic foot amputations (1 month after amputation); 101 family caregivers (7 months after amputation); 84 family caregivers (up to 10 months after amputation); Living at home | (i) Mental health and psychological needs (iv) Supportive care needs (v) Social support needs | Family caregivers show signs of stress during the first month after patient’s amputation. Traumatic stress mediates the relationship between caregiver stress and mental QoL, emphasizing the importance of mental health in the family caregiver. Family caregivers need help in caregiving, especially 1 month after amputation, because of the increase in caregiving burden. Between 1 and 7 months after amputation, family caregivers show signs of traumatic stress with negative consequences in caregiving, needing social support in caregiving to help them with the increase traumatic stress in this period. |
Costa et al. (2020) [29], Portugal | Longitudinal Study (Quantitative) | 110 family caregivers of people with diabetic foot amputations (1 month after amputation); 101 family caregivers (7 months after amputation); 84 family caregivers (up to 10 months after amputation); Living at home | (i) Mental health and psychological needs (ii) Physical health needs (iv) Supportive care needs | Between 1 and 7 months after surgery appears to be a critical period, given the increase in physical symptoms; caregivers who presented high levels of physical symptomatology showed low levels of mental QoL over time. Seven months after the amputation, caregivers experience a greater number of physical symptoms, due to the strain of caring for patients with reduced mobility. In the period between 1 and 7 months after amputation, an increase occurs in the physical symptomatology of the family caregivers due to exhaustion, needing support in caregiving tasks to help deal with physical exhaustion. |
Costa et al. (2018) [30], Portugal | Longitudinal Study (Quantitative) | 110 family caregivers of people with diabetic foot amputations (1 month after amputation); 101 family caregivers (7 months after amputation); 84 family caregivers (up to 10 months after amputation); Living at home | (iv) Supportive care needs (v) Social support needs | Family caregivers need increasing help with caregiving activities up to 10 months after amputation, to prevent the burden and stress of care from increasing over time. Caregiver burden increases in the first seven months after amputation and family or social support are needed to prevent the development of caregiving burden and other symptoms. |
Tsoulou et al. (2019) [31], Grece | Cross-sectional Study (Quantitative) | 50 hospitalized patients who had undergone traumatic amputations (lower limb, fingers) and 50 family caregivers; Hospital discharge/returning home | (i) Mental health and psychological needs | Caregivers frequently put others’ needs before their own and sacrifice leisure time. Patients’ and caregivers’ psychological state is of great importance for effective treatment. After hospital discharge, 80% of the caregivers were referred for psychological counseling. |
Ganjparvar et al. (2016) [32], Iran | Cross-sectional Study (Quantitative) | 232 amputees with LLA due to different injuries during war and 232 family caregivers (wives); Living at home | (i) Mental health and psychological needs (ii) Physical health needs (iii) Health and well-being needs (v) social support needs | Caregivers need to assess care and service to maintain physical and mental health and help to promote their QoL. Caregivers responsible for the care of the person with amputations from the beginning of their condition have a lower quality of life (QoL) in the domain of physical functioning with limitations in physical activity. Caregivers of the person with bilateral LLAs have unfulfilled health and well-being needs and a poor QoL. Caregivers have lower scores in the domain of general health when compared with the general population. Compared with the general population, family caregivers of people with LLAs have lower scores in social function and mental health. Social support helps to mitigate the effect of caregivers’ burden. |
Foss et al. (2009) [33], Brazil | Descriptive Cross-sectional Study (Quantitative) | 87 family caregivers of people with dysvascular LLAs; Living at home | (i) Mental health and psychological needs | The emotional aspect of LLA caregivers associated with general tension, isolation, disappointment, and environment is significant. LLAs’ caregivers need guidance and psychological support. |
Bennett, J. (2016) [34], USA | Literature Review | Amputees with LLAs due to diabetes; Hospital discharge/returning home | (vi) Educational/Informational needs | Communication is essential for consistency in the planning of care for the patient and their caregivers. Postoperative care along with communication among health providers, patients, and their families are essential for a successful transition to a new life. |
Latlief et al. (2012) [35], USA | Literature Review | Amputees with LLAs due to dysvascular conditions or traumatic events; Returning home | (vi) Educational/Informational needs | There is a greater risk of injury in family caregivers of the person with amputation, transferring into/out of chairs, cars, beds, bathtubs, and other environments, given that most of them are untrained. Families of the person with a LLA need to be educated on issues such as skin monitoring, stump sock management, donning and doffing prosthesis, residual limb hygiene, and componentry inspection and maintenance. |
