Patient and Caregiver Health-related Quality of Life and Caregiver Burden While Awaiting Heart Transplantation: Findings From the Sustaining Quality of Life of the Aged: Heart Transplant or Mechanical Support (SUSTAIN-IT) Study.

ABSTRACT:

Background

We sought to compare change over time (baseline to 2 y) in health-related quality of life (HRQOL) between older (60-80 y) patients awaiting heart transplantation (HT) with mechanical circulatory support (MCS) versus without MCS and their caregivers and caregiver burden.

Methods

This study was conducted at 13 United States sites. Patient HRQOL was examined using the EuroQol 5-dimensional questionnaire (EQ-5D-3L) and Kansas City Cardiomyopathy Questionnaire-12 (KCCQ-12). Caregiver measures included the EQ-5D-3L and Oberst Caregiving Burden Scale, measuring time on task and difficulty. Analyses included analysis of variance, χ², and linear regression.

Results

We enrolled 239 HT candidates (n = 118 with MCS and n = 121 without MCS) and 193 caregivers (n = 92 for candidates with MCS and n = 101 for candidates without MCS). Baseline differences in HRQOL were observed between HT candidates with and without MCS: EQ-5D-3L visual analog scale (VAS) score (67.7 ± 17.6 versus 54.1 ± 23.3, P < 0.001) and KCCQ-12 overall summary score (59.9 ± 21.0 versus 48.9 ± 21.6, P < 0.001), respectively. HT candidates with MCS had significantly higher EQ-5D-3L VAS scores and KCCQ-12 overall summary score across time versus without MCS. Baseline EQ-5D-3L VAS scores did not differ significantly between caregivers of HT candidates with and without MCS (84.6 ± 12.9 versus 84.3 ± 14.4, P = 0.9), respectively, nor were there significant between-group differences over time. Caregivers for HT candidates with MCS reported more task difficulty (range: 1 = not difficult to 5 = extremely difficult) versus caregivers for those without MCS at baseline (1.4 ± 0.5 versus 1.2 ± 0.3, P = 0.004) and over time.

Conclusions

Understanding differences in HRQOL and caregiver burden among older HT candidates with and without MCS and their caregivers may inform strategies to enhance HRQOL and reduce burden.

Project description:BackgroundCaregivers of adults with cancer often report a different understanding of the patient's prognosis than the oncologist. We examine the associations of caregiver-oncologist prognostic concordance with caregiver depressive symptoms, distress, and quality of life (QoL). We also explore whether these relationships differed by caregiver environment mastery, an individual's sense of control, and effectiveness in managing life situations.Materials and methodsWe used data from a national geriatric assessment cluster-randomized trial (URCC 13070) that recruited patients aged 70 years and older with incurable cancer considering any line of cancer treatment at community oncology practices, their caregivers, and their oncologists. At enrollment, caregivers and oncologists estimated the patient's prognosis (0-6 months, 7-12 months, 1-2 years, 2-5 years, and >5 years; identical responses were concordant). Caregivers completed the Ryff's environmental mastery at enrollment. At 4-6 weeks, caregivers completed the Patient Health Questionnaire-2 (depressive symptoms), distress thermometer, and 12-Item Short-Form Health Survey (quality of life [QoL]). We used generalized estimating equations in models adjusted for covariates. We then assessed the moderation effect of caregiver mastery.ResultsOf 411 caregiver-oncologist dyads (mean age = 66.5 years), 369 provided responses and 28% were concordant. Prognostic concordance was associated with greater caregiver depressive symptoms (β = 0.30; p = .04) but not distress or QoL. A significant moderation effect for caregiver depressive symptoms was found between concordance and mastery (p = .01). Specifically, among caregivers with low mastery (below median), concordance was associated with greater depressive symptoms (β = 0.68; p = .003).ConclusionsCaregiver-oncologist prognostic concordance was associated with caregiver depressive symptoms. We found a novel moderating effect of caregiver mastery on the relationship between concordance and caregiver depressive symptoms.Implications for practiceCaregiver-oncologist prognostic concordance is associated with greater caregiver depressive symptoms, particularly in those with low caregiver mastery. When discussing prognosis with caregivers, physicians should be aware that prognostic understanding may affect caregiver psychological health and should assess their depressive symptoms. In addition, while promoting accurate prognostic understanding, physicians should also identify strengths and build resilience among caregivers.

Project description:Background There is a paucity of research describing health-related quality of life (HRQOL) in older adults considered for advanced heart failure surgical therapies. Using data from our SUSTAIN-IT (Sustaining Quality of Life of the Aged: Heart Transplant or Mechanical Support) study, we aimed to compare HRQOL among 3 groups of older (60-80 years) patients with heart failure before heart transplantation (HT) or long-term mechanical circulatory support (MCS) and identify factors associated with HRQOL: (1) HT candidates with MCS, (2) HT candidates without MCS, or (3) candidates ineligible for HT and scheduled for long-term MCS. Methods and Results Patients from 13 US sites completed assessments, including self-reported measures of HRQOL (EuroQol-5 Dimension Questionnaire, Kansas City Cardiomyopathy Questionnaire-12), depressive symptoms (Personal Health Questionnaire-8), anxiety (State-Trait Anxiety Inventory-state form), cognitive status (Montreal Cognitive Assessment), and performance-based measures (6-minute walk test and 5-m gait speed). Analyses included ANOVA, χ2 tests, Fisher's exact tests, and linear regression. The sample included 393 patients; the majority of patients were White men and married. Long-term MCS candidates (n=154) were significantly older and had more comorbidities and a higher New York Heart Association class than HT candidates with MCS (n=118) and HT candidates without MCS (n=121). Long-term MCS candidates had worse HRQOL than HT candidates with and without MCS (EQ-5D visual analog scale scores, 46±23 versus 68±18 versus 54±23 [P<0.001] and Kansas City Cardiomyopathy Questionnaire-12 overall summary scores, 35±21 versus 60±21 versus 49±22 [P<0.001], respectively). In multivariable analyses, lower 6-minute walk distance, higher New York Heart Association class, depressive symptoms, and not being an HT candidate with MCS were significantly associated with worse overall HRQOL. Conclusions Our findings demonstrate important differences in overall and domain-specific HRQOL of older patients with heart failure before HT or long-term MCS. Understanding HRQOL differences may guide decisions toward more appropriate and personalized advanced heart failure therapies.

Project description:IntroductionThe rising prevalence of modifiable risk factors (eg, obesity, hypertension and physical inactivity) is causing an increase in possible avoidable complications in patients undergoing cardiac surgery. This study aims to assess whether a combined preoperative and postoperative multidisciplinary cardiac rehabilitation (CR) programme (Heart-ROCQ programme) can improve functional status and reduce surgical complications, readmissions and major adverse cardiac events (MACE) as compared with standard care.Methods and analysisPatients (n=350) are randomised to the Heart-ROCQ programme or standard care. The Heart-ROCQ programme consists of a preoperative optimisation phase while waiting for surgery (three times per week, minimum of 3 weeks), a postoperative inpatient phase (3 weeks) and an outpatient CR phase (two times per week, 4 weeks). Patients receive multidisciplinary treatment (eg, physical therapy, dietary advice, psychological sessions and smoking cessation). Standard care consists of 6 weeks of postsurgery outpatient CR with education and physical therapy (two times per week). The primary outcome is a composite weighted score of functional status, surgical complications, readmissions and MACE, and is evaluated by a blinded endpoint committee. The secondary outcomes are length of stay, physical and psychological functioning, lifestyle risk factors, and work participation. Finally, an economic evaluation is performed. Data are collected at six time points: at baseline (start of the waiting period), the day before surgery, at discharge from the hospital, and at 3, 7 and 12 months postsurgery.Ethics and disseminationThis study will be conducted according to the principles of the Declaration of Helsinki (V.8, October 2013). The protocol has been approved by the Medical Ethical Review Board of the UMCG (no 2016/464). Results of this study will be submitted to a peer-reviewed scientific journal and can be presented at national and international conferences.Trial registration numberNCT02984449.
