Nature-based virtual reality intervention to manage stress in family caregivers of allogeneic hematopoietic stem cell transplant recipients: a two-phase pilot study protocol. Front Psychiatry 2024; 15:1295097. [PMID: 38516258 PMCID: PMC10954866 DOI: 10.3389/fpsyt.2024.1295097] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2023] [Accepted: 02/21/2024] [Indexed: 03/23/2024] Open
Abstract
Millions of family members and/or friends in the U.S. serve as unpaid caregivers for individuals with chronic conditions, such as cancer. Caregiving for someone undergoing an intense allogeneic hematopoietic stem cell transplant (HSCT) is particularly demanding, with accompanying physical and psychological stress. Increased stress and stress-related symptoms could make it difficult for caregivers to fulfill their roles and could negatively impact the health status and quality of life of themselves and the recipients. Virtual reality (VR) is a promising technology increasingly used for treatment and wellness in various medical settings. There is growing evidence that studies have reported the positive effects of the VR intervention in managing and reducing stress among diverse populations in various clinical scenarios; however, no published studies have focused on family caregivers of patients with cancer. The study aims to assess the feasibility and acceptability of a four-week nature-based VR intervention and to examine the effectiveness of the VR intervention on stress in HSCT caregivers. This study comprises two phases. Phase I of the study will be a single-arm pre-post design focused on assessing the feasibility and acceptability of the VR intervention. Phase II of the study will be a prospective randomized controlled group design to examine the effectiveness of the VR intervention on perceived stress. Adults (≥ 18 years) who serve as primary caregivers for a person who will undergo an allogeneic HSCT will be recruited. Fifteen participants will be enrolled for Phase I and 94 participants for Phase II (Active VR arm N=47; Sham VR arm N=47). The nature-based immersive VR program contains 360° high-definition videos of nature scenes along with nature sounds through a head-mounted display (HMD) for 20 minutes every day for four weeks. Primary outcome is perceived stress measured by the Perceived Stress Scale. Secondary/exploratory outcomes are stress-related symptoms (e.g., fatigue, sleep disturbance) and physiological biomarkers (e.g., cortisol, alpha-amylase). The importance and innovativeness of this study consist of using a first-of-its-kind, immersive VR technology to target stress and investigating the health outcomes assessed by validated objective biomarkers as well as self-report measures of the nature-based intervention in the caregiver population. Clinical trial registration ClinicalTrials.gov, identifier NCT05909202.

Lee LJ, Son H, Wallen GR, Flynn S, Cox R, Yang L, Ross A. Symptom Clusters in Family Caregivers of Hematopoietic Stem Cell Transplantation Recipients: Loneliness as a Risk Factor. Transplant Cell Ther 2023; 29:50.e1-50.e8. [PMID: 36202335 PMCID: PMC9825650 DOI: 10.1016/j.jtct.2022.09.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2022] [Revised: 09/20/2022] [Accepted: 09/25/2022] [Indexed: 11/06/2022]
Abstract
A symptom cluster is a group of 2 or more symptoms that occur together and are related to each other. Family caregivers of allogeneic hematopoietic stem cell transplantation (HSCT) recipients experience multiple concurrent symptoms, but the majority of symptom research in this population has focused on assessing and managing individual symptoms. The purpose of this analysis was to determine (1) whether clusters of 5 highly prevalent symptoms (fatigue, sleep disturbance, depression, anxiety, and cognitive impairment) in allogeneic HSCT caregivers could be identified and (2) which caregiver and patient characteristics influence membership in the identified symptom cluster groups. Baseline cross-sectional data were collected from allogeneic HSCT caregivers participating in a randomized controlled trial at the National Institutes of Health Clinical Center. Measures included the Caregiver Reaction Assessment (CRA), Health-Promoting Lifestyle Profile II (HPLP-II), Fatigue Symptom Inventory (MFSI), Pittsburgh Sleep Quality Index (PSQI), and Patient-Reported Outcomes Measurement Information System (PROMIS). Cluster analysis was used to identify symptom clusters, and univariate analyses and multiple logistic regression were performed to identify factors that contribute to symptom clusters. The average age of caregivers (n = 44) was 45.20 ± 15.05 years; primarily white (52.3%) and female (88.6%) and often the spouse/partner of the patient (50.0%). Two symptom cluster groups were identified: low symptom burden (n = 24; 54.5%) and high symptom burden (n = 20; 45.5%). Caregivers with higher levels of loneliness (odds ratio, 1.12; 95% confidence interval, 1.04 to 1.22; P = .004) were more likely to be in the high symptom burden group. This study provides evidence that 5 symptoms commonly found in family caregivers-fatigue, sleep disturbance, depression, anxiety, and cognitive impairment-tend to occur in clusters. Therefore, clinicians should be aware that caregivers with 1 or more of these symptoms may be at higher risk for developing the others, and caregivers reporting high levels of loneliness may be at particular risk. Future research is needed to identify novel interventions that target multiple, co-occurring symptoms. Such interventions also might include components that decrease loneliness. © 2022 American Society for Transplantation and Cellular Therapy. Published by Elsevier Inc.

Effects of a yoga-based stress reduction intervention on stress, psychological outcomes and cardiometabolic biomarkers in cancer caregivers: A randomized controlled trial. PLoS One 2022; 17:e0277009. [DOI: 10.1371/journal.pone.0277009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2022] [Accepted: 10/18/2022] [Indexed: 11/12/2022] Open
Abstract
Caregiving stress is a risk factor for cardiometabolic disease. Therefore, integrating cardiometabolic biomarkers into caregiving research provides a more comprehensive assessment of an individual’s health and response to an intervention. The objective of this study was to examine the effects of a yoga-based stress reduction intervention on stress, psychological outcomes, and cardiometabolic biomarkers in cancer caregivers. This prospective randomized controlled trial enrolled family caregivers of adult patients who underwent an allogeneic HSCT at the National Institutes of Health (NIH) Clinical Center. All subjects received usual care education. Participants in the intervention group received an Iyengar yoga intervention self-administered over six weeks using an audio recording file. The primary outcome was perceived stress (measured using the NIH toolbox Perceived Stress). The secondary outcomes were psychological factors (depression and anxiety measured using PROMIS® Depression and Anxiety), and cardiometabolic biomarkers measured by nuclear magnetic resonance spectroscopy. A total of 50 family caregivers (mean [SD] age, 44.9 [15.2] years; 42 [84.0%] women) were randomized, 25 to the intervention group and 25 to the control group. No group differences were noted in stress, depression, and anxiety. Significant interaction effects between group and time were found in large TRL-P (F(1,43) = 10.16, p = 0.003) and LP-IR (F(1,42) = 4.28, p = 0.045). Post-hoc analyses revealed that the levels of large TRL-P (mean difference = 1.68, CI = [0.86, 2.51], p< .001) and LP-IR (mean difference = 5.67, CI = [1.15, 10.18], p = 0.015) significantly increased over time in the control group but while remained stable in the intervention group (mean difference = -0.15, CI = [-0.96, 0.66], p = 0.718; mean difference = -0.81, CI = [-5.22, 3.61], p = 0.714, respectively). Even when perceptions of psychological distress remain unchanged, incorporating gentle yoga poses and breathing exercises may reduce the risk of cardiometabolic disease in caregivers by inhibiting the development of insulin resistance. Standard lipids of cardiometabolic risk do not appear to be robust enough to detect short-term early changes of cardiometabolic risk in caregivers.

Menekli T, Şentürk S. Caregiver burden and the perceived social support of the family caregivers of the patients awaiting hematopoietic stem cell transplantation. Transpl Immunol 2022; 71:101535. [PMID: 35007742 DOI: 10.1016/j.trim.2022.101535] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Revised: 12/29/2021] [Accepted: 01/06/2022] [Indexed: 11/16/2022]
Abstract
BACKGROUND This study aims to identify the caregiver burden and the level of perceived social support of the family caregivers who provided care to patients awaiting hematopoietic stem cell transplantation. METHODS Designed as a descriptive and cross-sectional study, this research was conducted with 451 caregivers of patients who awaited stem cell transplantation and paid visits for examination to the polyclinic of the Bone Marrow Transplantation Center from 7 June 2021 to 1 September 2021. The research data were collected by using the Patient and Caregiver Information Form, the Zarit Caregiver Burden Scale (ZCBS), and the Multidimensional Scale of Perceived Social Support (MSPSS). The data analysis was conducted by using descriptive statistics, independent samples t-test, one-way analysis of variance, Pearson correlation test, and linear regression. RESULTS The mean age of the caregivers was 32.51 ± 2.70 years. The perceived social support of the caregivers was at low level (MSPSS: 32.30 ± 25.1) while the caregiver burden was found at high level (ZCBS: 50.1 ± 9.8). Besides, it was discerned that the mean scores obtained by the caregivers from the Multidimensional Scale of Perceived Social Support and its sub-scales had medium-level statistically significant negative relationships with the mean of their Zarit Caregiver Burden Scale scores (p < 0.05). CONCLUSIONS The results show that the caregivers being away from their families and social environment during the care process and that there was nobody to help them increases the burden of caregiving. It is recommended that caregivers should be evaluated by health personnel, and initiatives should be planned to reduce the burden of care and increase social support.
