Predictors of caregiver burden in caregivers of individuals with traumatic or non-traumatic brain injury: A scoping review

Family member reported symptom burden, predictors of caregiver burden and treatment effects in a goal-oriented community-based randomized controlled trial in the chronic phase of traumatic brain injury

BACKGROUND

Family members are often affected by the long-term consequences of traumatic brain injury, but are rarely involved in rehabilitation programs in the chronic phase. We thus do not know what family members´ main concerns are in the chronic phase, what factors are associated with perceived caregiver burden, and whether family members´ health and functioning improves due to rehabilitation efforts received by the patients. This study explored family-members` functioning, predictors of caregiver burden and effect for family members of a goal-oriented intervention in the chronic phase of traumatic brain injury.

METHODS

Family members self-reported data measuring their caregiver burden, depression, general health, loneliness, and their evaluation of patient competency in everyday life, patient awareness levels, main problem areas (target outcomes) for the patient related to the brain injury, and demographic data were collected. Regression models were used to explore predictors of caregiver burden, and mixed models analysis was used to explore treatment effects.

RESULTS

In total, 73 family members were included, 39 in the intervention group and 34 in the control group. Moderate to high caregiver burden was reported by 40% of family members, and 16% experienced clinical levels of depression. Family member loneliness and their evaluation of the patient`s level of functional competency explained 57% of the variability in caregiver burden. There were no treatment-related changes in caregiver burden, family member depression or general health. At T2 there was however a significant reduction in how family members rated severity of target outcomes that the family members had nominated at baseline (-0.38, 95% CI, -0.75 to -0.02, p = 0.04), but not for the target outcomes the patients had nominated.

CONCLUSIONS

A significant proportion of family members to patients in the chronic phase of TBI continue to experience challenging caregiver burden and emotional symptoms. Both family member-related and patient factors contribute to caregiver burden. Interventions targeting patient complaints do not automatically alleviate family members´ burden. It is important to address social support for family members early after injury, and there is a need for more interventions specifically targeting family members´ needs.

TRIAL REGISTRATION

The trial was registered at ClinicalTrials.gov, NCT03545594 on the 4th of June 2018.

Caregiver Burden and Readiness in Patients with Moderate and Severe Traumatic Brain Injury: The Chain Mediation Effect of Disease Uncertainty and Mental Resilience

OBJECTIVE

To analyze the mediating effects of caregiver illness uncertainty and psychological resilience in caregiver burden and readiness in patients with moderate-to-severe traumatic brain injuries (TBIs). This can help improve caregiver readiness in patients with moderate-to-severe TBIs.

METHODS

A purposive sampling method was used to recruit patients with moderate-to-severe TBIs, and their caregivers, who were hospitalized in the Department of Neurosurgery of the Affiliated Hospital of Yangzhou University between October 2022 and August 2023. The Zarit Caregiver Burden Interview, Mishel Uncertainty In Scale for Family Member, Connor-Davidson Resilience Scale, and Caregivers Preparedness Scale, as well as general information questionnaire, were used to conduct the survey.

RESULTS

Caregiver readiness correlated with caregiver burden, illness uncertainty, and psychological resilience in patients with moderate-to-severe TBI (P < 0.01). Caregiver readiness was not only directly affected by caregiver burden (95% confidence interval: -0.510, -0.196) but was also affected through the chain mediation of illness uncertainty and psychological resilience (95% confidence interval: -0.146, -0.011).

CONCLUSIONS

Caregiver burden in patients with moderate-to-severe TBI influences caregiver readiness levels and is mediated by illness uncertainty and psychological resilience. By improving caregivers' illness uncertainty and increasing their psychological resilience, the impact of low caregiver readiness caused by high caregiver burden could be reduced.

The burden of traumatic brain injury on caregivers: exploring the predictive factors in a multi-centric study

BACKGROUND

Traumatic brain injury (TBI) is a significant cause of mortality and morbidity worldwide. With survivors often exhibiting degrees of function loss, a significant burden is exerted on their caregivers. The purpose of this study was to explore the predictive factors of caregiver burden among caregivers of patients with TBI.

METHODS

Sixty-eight family members of individuals with a TBI who had been admitted to three hospitals were assessed in terms of caregiver burden using the Zarit Burden Interview. The association of caregiver burden with patients' baseline cognitive function according to the Montreal Cognitive Assessment (MoCA) test, as well as caregivers' sociodemographic characteristics, were evaluated using multiple regression analysis.

RESULTS

Based on the multiple regression model, the MoCA score of the patients (std β=-0.442, p < 0.001), duration of caregiving (std β = 0.228, p = 0.044), and higher education of the caregivers (std β = 0.229, p = 0.038) were significant predictors of caregiver burden.

CONCLUSION

Overall, our findings highlight the importance of taking caregivers' psychosocial needs into account. Long-term caregivers of TBI patients with cognitive impairment should be viewed as vulnerable individuals who could benefit from psychosocial intervention programs, to improve their well-being and enabling them to enrich their care of the TBI patient.
