A novel psychosocial virtual reality intervention (BMT-VR) for patients undergoing hematopoietic stem cell transplantation: Pilot randomized clinical trial design and methods

BACKGROUND

Although patients undergoing hematopoietic stem cell transplantation (HSCT) must cope with psychological distress and isolation during an extended transplant hospitalization, psychosocial interventions to address these unmet needs are lacking. Virtual reality offers an innovative modality to deliver a patient-centered psychosocial intervention to address psychosocial needs of patients undergoing HSCT. However, there are currently no supportive care interventions leveraging virtual reality in patients undergoing HSCT.

OBJECTIVE

To describe the methods of a randomized clinical trial (RCT) to assess the feasibility and preliminary efficacy of a self-administered, virtual reality-delivered psychosocial intervention (BMT-VR) to improve psychological distress and quality of life (QOL) for patients hospitalized for HSCT.

METHODS

This study entails a single-center RCT of BMT-VR compared to usual transplant care in 80 patients hospitalized for HSCT. Adult patients with hematologic malignancies hospitalized for autologous or allogeneic HSCT are eligible. BMT-VR includes psychoeducation about the HSCT process, psychosocial skill building to promote effective coping and acceptance, and self-care and positive psychology skills to promote post-HSCT recovery. The primary aim is to assess the feasibility defined a priori as ≥60% of eligible patients enrolling in the study, and of those enrolled and randomized to the BMT-VR, ≥ 60% completing 4/6 BMT-VR modules. Secondary objectives include assessing the preliminary effects on psychological distress and QOL.

DISCUSSION

This is the first RCT of a virtual reality-delivered psychosocial intervention for the HSCT population. If deemed feasible, a future larger multi-site clinical trial can evaluate the efficacy of BMT-VR on outcomes for patients hospitalized for HSCT.

A Positive Psychology Intervention for Caregivers of Hematopoietic Stem Cell Transplantation Survivors (PATH-C): Initial Testing and Single-Arm Pilot Trial

Caregivers of patients with hematologic malignancies undergoing allogeneic hematopoietic stem cell transplantation (HSCT) play a crucial role in supporting their loved ones through physical, emotional, and practical challenges. This role has been associated with high levels of psychological distress and low levels of positive psychological well-being (PPWB). Positive psychology interventions for caregivers in other disease groups (eg, breast cancer) have been associated with improved outcomes. However, positive psychology interventions that specifically address HSCT caregivers' psychological needs are currently lacking. The goal of this single-arm open-pilot trial was to determine the feasibility and acceptability of the Positive Affect in the Transplantation of Hematopoietic Stem Cells (PATH) intervention for HSCT Caregivers to identify caregiver preferences to tailor PATH for HSCT caregivers. Adult caregivers of HSCT recipients were eligible for PATH during the HSCT recipient's first 100 d post-transplant. We defined, a priori, feasibility as >60% of participants who start the intervention completing ≥6/9 intervention sessions and acceptability as weekly ratings of ease and utility of the PP exercises ≥7/10 on a 10-point Likert Scale (0 = very difficult/not helpful; 10 = very easy/very helpful). We conducted semistructured qualitative exit interviews (n = 15) to explore HSCT caregivers' perception of PATH's content, benefits of PATH, as well as facilitators and barriers to engaging with the intervention. Transcribed interviews were analyzed using framework-guided rapid analysis by 2 coders. The intervention was feasible with 83% (15/18) of caregivers who started the intervention completing ≥6/9 intervention sessions. Among caregivers who completed ≥6/9 intervention sessions, ratings of ease (mean = 8.1; 95% CI: 7.4, 8.7) and utility (mean = 8.3; 95% CI: 7.8, 8.9) also exceeded our a priori threshold of ≥7/10. Caregivers identified benefits of PATH, including identifying and responding to emotions, dedicating time to self-care, and cultivating important relationships. Sociodemographic factors (eg, being retired) and the manualized structure of PATH were cited as facilitators to intervention engagement. Barriers to PATH engagement included lack of time and competing caregiving responsibilities. Caregivers preferred remote intervention delivery within the first 100 d post HSCT. This is the first study to show a 9-wk, phone-delivered positive psychology intervention is feasible in caregivers of allogeneic HSCT recipients. Our findings also underscore the specific preferences of this population for positive psychology interventions. Larger studies are warranted to establish the efficacy of these interventions in addressing persistent unmet psychological needs for HSCT caregivers.

Study protocol for a randomized trial of a supportive care mobile application to improve symptoms, coping, and quality of life in patients with advanced non-small cell lung cancer

Patients with advanced non-small cell lung cancer (NSCLC) often experience burdensome symptoms, emotional distress, and poor quality of life (QOL). While national guidelines recommend early palliative care to address these supportive care needs, most patients with advanced NSCLC lack access to such comprehensive care. Our aim in the current study is to test a novel model of palliative care delivery and use of innovative technology to evaluate the feasibility, acceptability, and preliminary efficacy of a supportive care mobile application (app) for improving symptom management and adaptive coping in patients with advanced NSCLC. We will enroll 120 patients with unresectable Stage III or IV NSCLC diagnosed within the past 12 weeks receiving care with palliative intent at a major academic comprehensive cancer center and its community affiliates. The study will take place in two phases, the first of which will be dedicated to adapting an evidence-based, early palliative care treatment guide and prior supportive care mobile app intervention to address the specific symptom management and coping needs of patients with advanced NSCLC. The second phase of the study will be a two-group, randomized controlled trial. Study patients will complete baseline self-report measures of symptoms, mood, coping skills, and QOL, after which they will be randomized to receive either the mobile app intervention combined with usual oncology care or usual oncology care alone. Intervention patients will use a tablet computer to self-administer the mobile app, which consists of six modules that teach evidence-based skills for managing burdensome symptoms and coping effectively with advanced cancer and its treatment. At 12 weeks follow up, patients in both groups will repeat the same self-report measures. We will use descriptive statistics to determine feasibility metrics of enrollment and retention rates. For secondary self-report measures, we will use linear regression controlling for baseline values. The results of the present study will contribute to a growing body of evidence regarding the supportive care needs of patients with advanced cancer and will have implications for how best to use innovative technology to widely disseminate comprehensive supportive care services to all patients who may benefit.

Anxiety and Depression Symptoms in Caregivers Prior to Hematopoietic Stem Cell Transplantation (HCT)

Family and friends caring for hematopoietic stem cell transplantation (HCT) recipients experience substantial disruptions in daily life as they prepare for transplant. These disruptions may increase their psychological distress, yet little research has described the extent of this distress. The goals of the present study were to characterize rates of anxiety and depression symptoms immediately prior to HCT and their relationship with modifiable caregiving domains. We conducted a secondary analysis of cross-sectional data of caregivers of patients undergoing HCT. Caregivers completed self-report measures to assess 8 domains of caregiving (Caregiver Oncology Quality of Life Questionnaire) and anxiety and depression symptoms (Hospital Anxiety and Depression Scale [HADS]) prior to transplant. Scores ≥8 on the HADS anxiety and depression subscales signified clinically significant symptoms. We used multivariable regression models adjusting for age, sex, caregiver relationship, and HCT type to examine the associations between caregiving domains and anxiety and depression symptoms. We enrolled 193 caregivers (median age = 60 years, 70.0% female, 52.3% allogeneic transplant). A majority of participants were providing care for a spouse (79.8%), followed by a child (7.8%) or parent (5.2%). On average, caregivers reported more anxiety (mean = 7.04, SD = 3.94) than depression symptoms (mean = 4.18, SD = 3.49), with 46.6% and 16.1% endorsing clinically significant anxiety and depression symptoms, respectively. Caregiver anxiety was associated with worse physical well-being, less leisure time, and poorer coping (Ps < .05). Caregiver depression symptoms were associated with worse physical well-being and less leisure time (Ps < .05). Caregivers of HCT recipients experience substantial psychological distress, particularly anxiety, prior to transplant. This distress is linked to modifiable caregiving domains. Study findings identify possible targets for psychosocial interventions aimed at managing caregiver anxiety and depression symptoms as well as highlight the need for intervention early during the course of transplant.

Multimodal psychosocial intervention for family caregivers of patients undergoing hematopoietic stem cell transplantation: A randomized clinical trial

BACKGROUND

Caregivers of patients undergoing hematopoietic stem cell transplantation (HCT) experience an immense caregiving burden before, during, and after HCT.

METHODS

We conducted an unblinded, randomized trial of a psychosocial intervention (BMT-CARE) for caregivers of patients undergoing autologous and allogeneic HCT at Massachusetts General Hospital. Caregivers were randomly assigned to BMT-CARE or usual care. BMT-CARE was tailored to the HCT trajectory and integrated treatment-related education and self-care with cognitive-behavioral skills to promote coping. Caregivers assigned to BMT-CARE met with a trained interventionist (a psychologist or a social worker) in person, via telephone, or via videoconferencing for 6 sessions starting before HCT and continuing up to day +60 after HCT. The primary endpoint was feasibility, which was defined as at least 60% of eligible caregivers enrolling and completing 50% or more of the intervention sessions. We assesed caregiver quality of life (QOL; Caregiver Oncology Quality of Life Questionnaire), caregiving burden (Caregiver Reaction Assessment), psychological distress (Hospital Anxiety and Depression Scale), self-efficacy (Cancer Self-Efficacy Scale-Transplant), and coping (Measures of Current Status) at baseline and 30 and 60 days after HCT. We used mixed linear effect models to assess the effect of BMT-CARE on outcomes longitudinally.

RESULTS

We enrolled 72.5% of eligible caregivers (100 of 138), and 80% attended 50% or more of the intervention sessions. Caregivers randomized to BMT-CARE reported improved QOL (B = 6.11; 95% CI, 3.50-8.71; P < .001), reduced caregiving burden (B = -6.02; 95% CI, -8.49 to -3.55; P < .001), lower anxiety (B = -2.18; 95% CI, -3.07 to -1.28; P < .001) and depression symptoms (B = -1.23; 95% CI, -1.92 to -0.54; P < .001), and improved self-efficacy (B = 7.22; 95% CI, 2.40-12.03; P = .003) and coping skills (B = 4.83; 95% CI, 3.04-6.94; P < .001) in comparison with the usual-care group.

CONCLUSIONS

A brief multimodal psychosocial intervention tailored for caregivers of HCT recipients is feasible and may improve QOL, mood, coping, and self-efficacy while reducing the caregiving burden during the acute HCT period.
