Supporting Individuals With an Acquired Brain Injury: An Interpretative Phenomenological Study Exploring the Everyday Lives of Caregivers

Acquired brain injury (ABI) is one of the most common causes of disability and death globally. Support from informal caregivers is critical to the well-being and quality of life of people with ABI and supports the sustainability of global health and social care systems. This study presents an in-depth qualitative analysis of the experiences of eight British informal caregivers supporting someone with ABI. Semi-structured interviews were conducted with narratives transcribed verbatim and analysed using interpretative phenomenological analysis (IPA). Three superordinate themes were generated: making sense of brain injury; being consumed by caregiving; and, the changing self. These data highlight the impact of caregiving on the caregiver's illness perceptions and sense of self. By identifying negative and positive changes in the caregiver's sense of self, and dilemmas regarding the care recipient's behaviour, we address less understood aspects of caregiver experiences. Caregiving can pose both challenges to the caregiver's sense of identity and an opportunity for self-growth. Some caregivers exhibit resilience throughout their journey, with post-traumatic growth more apparent in the later stages of caregiving. Illness perceptions shape caregiver well-being and family dynamics and indicate the need to address stigmatisation and discrimination faced by ABI survivors and caregivers. Although some caregivers acquired positive meaning and enrichment from their caregiving, previously described challenges of ABI caregiving are supported. Overall, our findings support the need for timely psychological/mental health support for caregivers, caregiver education, and the provision of short breaks from caregiving.

Physiological and radiological parameters predicting outcome from penetrating traumatic brain injury treated in the deployed military setting

INTRODUCTION

Penetrating traumatic brain injury (TBI) is the most common cause of death in current military conflicts, and results in significant morbidity in survivors. Identifying those physiological and radiological parameters associated with worse clinical outcomes following penetrating TBI in the austere setting may assist military clinicians to provide optimal care.

METHOD

All emergency neurosurgical procedures performed at a Role 3 Medical Treatment Facility in Afghanistan for penetrating TBI between 01 January 2016 and 18 December 2020 were analysed. The odds of certain clinical outcomes (death and functional dependence post-discharge) occurring following surgery were matched to existing agreed preoperative variables described in current US and UK military guidelines. Additional physiological and radiological variables including those comprising the Rotterdam criteria of TBI used in civilian settings were additionally analysed to determine their potential utility in a military austere setting.

RESULTS

55 casualties with penetrating TBI underwent surgery, all either by decompressive craniectomy (n=42) or craniotomy±elevation of skull fragments (n=13). The odds of dying in hospital attributable to TBI were greater with casualties with increased glucose on arrival (OR=70.014, CI=3.0399 to 1612.528, OR=70.014, p=0.008) or a mean arterial pressure <90 mm Hg (OR=4.721, CI=0.969 to 22.979, p=0.049). Preoperative hyperglycaemia was also associated with increased odds of being functionally dependent on others on discharge (OR=11.165, CI=1.905 to 65.427, p=0.007). Bihemispheric injury had greater odds of being functionally dependent on others at discharge (OR=5.275, CI=1.094 to 25.433, p=0.038).

CONCLUSIONS

We would recommend that consideration of these three additional preoperative clinical parameters (hyperglycaemia, hypotension and bihemispheric injury on CT) when managing penetrating TBI be considered in future updates of guidelines for deployed neurosurgical care.
