Study protocol for NeuroCARE: a randomised controlled trial of a psychological intervention for caregivers of patients with primary malignant brain tumours.

INTRODUCTION: Caregivers of patients with primary malignant brain tumours experience substantial psychological distress while caring for someone with a progressive, life-limiting neurological illness. However, there are few interventions aimed at addressing the psychosocial needs of this population. We developed and are testing a population-specific, evidence-based, telehealth intervention (NeuroCARE) to reduce anxiety symptoms and improve psychosocial functioning in this caregiver population. METHODS AND ANALYSIS: This study is a non-blinded, randomised controlled trial of a psychological intervention for caregivers of patients with primary malignant brain tumours receiving care at the Massachusetts General Hospital Cancer Center or Dana-Farber Cancer Institute. We will enrol 120 caregivers who screen positive for heightened anxiety. Participants will be randomised 1:1 to the NeuroCARE intervention or a usual care control condition. Caregivers assigned to NeuroCARE will complete six individual telehealth sessions with a trained behavioural health specialist over 12 weeks. Caregivers randomised to the control condition will receive usual care, including possible referral to social work or other appropriate resources. Participants will complete self-report questionnaires at baseline and 11 weeks and 16 weeks postrandomisation. The primary outcome is anxiety symptoms at 11 weeks among NeuroCARE participants, compared with usual care. Secondary outcomes include caregiver-reported depressive symptoms, quality of life, caregiver burden, caregiving self-efficacy, perceived coping skills and post-traumatic stress disorder symptoms. We also will explore potential mediators of the NeuroCARE effect on caregiver anxiety symptoms. ETHICS AND DISSEMINATION: The study is funded by a Career Development Award from Conquer Cancer, the American Society of Clinical Oncology Foundation (award number 2019CDA-7743456038) and approved by the Dana-Farber/Harvard Cancer Center Institutional Review Board (Protocol #19-250 V.10.1). The study will be reported in accordance with the Consolidated Standards of Reporting Trials statement for non-pharmacological trials. Results will be presented at scientific meetings and in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT04109209.

Characterizing Distress and Identifying Modifiable Intervention Targets for Family Caregivers of Patients with Malignant Gliomas.

Background: Individuals caring for patients with malignant gliomas experience high rates of anxiety; however, an in-depth understanding of their distress and evidence-based interventions to target their needs are lacking. Objective: We conducted semistructured interviews with caregivers with elevated anxiety to characterize their drivers of anxiety, identify modifiable intervention targets, and capture their preferences for a psychosocial intervention. Design: From 9/2017 to 3/2019, we conducted semistructured interviews with 21 caregivers of patients with malignant gliomas, at time points following the patient's diagnosis or within one to three months after the patient's death. Setting/Subjects: Eligible caregivers in the United States had clinically significant anxiety as measured by a Hospital Anxiety and Depression Scale-Anxiety score >7. Measurements: Three independent coders employed thematic content analysis to analyze the qualitative data with NVivo 12, achieving high intercoder agreement (Kappa = 0.98). Results: On average, caregivers were 54.81 years old (SD = 10.85) with elevated anxiety (M = 10.90, SD = 3.25). We identified six themes in which caregivers described (1) coping through reassurance seeking or avoidance, (2) changes in their relationship with the patient, (3) challenges with social support, (4) vacillation between certainty and uncertainty regarding the future, (5) devaluation of self-care for the patients' needs, and (6) challenges communicating with the health care team. Caregivers were interested in an intervention soon after the patient's diagnosis, yet expressed concern about finding the time to participate. Conclusions: Emergent themes characterized the distress experienced by caregivers of patients with malignant gliomas and provided insight into their psychosocial intervention preferences. We identified evidence-based intervention components based on the modifiable factors arising from these themes.

Factors associated with psychological distress in caregivers of patients with malignant gliomas.

PURPOSE: Caregivers of patients with malignant gliomas are at risk for psychological distress. However, factors associated with distress in this population have not been well described. We conducted a prospective study evaluating psychological distress in patients with malignant gliomas and their caregivers and exploring factors associated with caregiver distress. METHODS: We enrolled patients with newly diagnosed malignant gliomas (N = 77) and their caregivers (N = 61). At baseline and 3, 6, and 9 months after diagnosis, we administered the Hospital Anxiety and Depression Scale to assess psychological distress and the Caregiver Reaction Assessment to evaluate caregiver burden. We performed multivariable regression analyses to investigate caregiver-related, patient-related, and tumor-related factors associated with caregivers' distress. RESULTS: At baseline, 48.3% (29/60) and 26.2% (16/61) of caregivers reported clinically significant anxiety and depression symptoms, respectively. Anxiety and depression symptoms persisted over time. Greater caregiver depression was associated with male gender (B = 1.48, 95% CI 0.16-2.81, p = 0.03), higher caregiver burden (B = 0.08, 95% CI 0.01-0.15, p = 0.02), caregiver anxiety (B = 0.53, 95% CI 0.38-0.68, p < 0.0001), patient depression (B = 0.34, 95% CI 0.13-0.55, p = 0.002), and caring for a younger patient (B = -0.07, 95% CI -0.15 to 0.00, p = 0.049). Factors associated with greater caregiver anxiety symptoms were caregiver depression (B = 0.91, 95% CI 0.71-1.12, p < 0.0001) and younger patient age (B = -0.15, 95% CI -0.24 to -0.05, p = 0.003). CONCLUSION: Male gender, higher caregiver burden, greater patient depression symptoms, and younger patient age are associated with increased distress among caregivers of patients with malignant gliomas, underscoring the need for tailored supportive care interventions targeting caregivers at highest risk for psychological distress.

Perceptions of prognosis and goal of treatment in patients with malignant gliomas and their caregivers.

BACKGROUND: Patients with malignant gliomas have a poor prognosis. However, little is known about patients' and caregivers' understanding of the prognosis and the primary treatment goal. METHODS: We conducted a prospective study in patients with newly diagnosed malignant gliomas (N = 72) and their caregivers (N = 55). At 12 weeks after diagnosis, we administered the Prognosis and Treatment Perceptions Questionnaire to assess understanding of prognosis and the Hospital Anxiety and Depression Scale to evaluate mood. We used multivariable regression analyses to explore associations between prognostic understanding and mood and McNemar tests to compare prognostic perceptions among patient-caregiver dyads (N = 48). RESULTS: A total of 87.1% (61/70) of patients and 79.6% (43/54) of caregivers reported that it was "very" or "extremely" important to know about the patient's prognosis. The majority of patients (72.7%, [48/66]) reported that their cancer was curable. Patients who reported that their illness was incurable had greater depressive symptoms (B = 3.01, 95% CI, 0.89-5.14, P = .01). There was no association between caregivers' prognostic understanding and mood. Among patient-caregiver dyads, patients were more likely than caregivers to report that their primary treatment goal was cure (43.8% [21/48] vs 25.0% [12/48], P = .04) and that the oncologist's primary goal was cure (29.2% [14/48] vs 8.3% [4/48], P = .02). CONCLUSIONS: Patients with malignant gliomas frequently hold inaccurate perceptions of the prognosis and treatment goal. Although caregivers more often report an accurate assessment of these metrics, many still report an overly optimistic perception of prognosis. Interventions are needed to enhance prognostic communication and to help patients cope with the associated distress.

Risk factors for developing posttraumatic stress disorder following childbirth.

Women can develop childbirth-related posttraumatic stress disorder (CB-PTSD) in at-term delivery with healthy baby outcome as well as following pre-term delivery and neonatal complications, a potential added stressor. No study compares risk factors of CB-PTSD associated with different infant outcomes. We investigated CB-PTSD risk factors by comparing women with or without neonatal complications. Analysis reveals the importance of antepartum and birth-related risk factors in CB-PTSD above and beyond child outcomes, suggesting childbirth is an independent stressor capable of evoking CB-PTSD.
