Family caregiver-reported outcomes regarding decision-making for left ventricular assist device implantation.

ABSTRACT: BACKGROUND:Family caregivers (FCGs) often participate in the decision for their loved one to receive a left ventricular assist device (LVAD). Little is known about the contribution of FCGs to this complex decision. OBJECTIVES:To investigate family caregiver-reported outcomes related to decision-making for LVAD implantation and their experiences post-implantation. METHODS:Descriptive thematic analysis was used to analyze longitudinal data. Thematic saturation was achieved. RESULTS:Three key themes emerged from the data. The main theme in the pre-implantation period was: Not a decision. The two themes in the post-implantation period were: More satisfaction than regret and Unanticipated situational change. CONCLUSIONS:Family caregiver-reported outcomes inform clinical practice and future research. FCGs of LVAD recipients did not see viable alternatives to LVAD implantation, were generally satisfied with post-implantation outcomes, and experienced unexpected life changes in the post-implantation period despite feeling prepared preoperatively. Education of both LVAD recipients and their FCGs must be optimized.

Project description:AimsImplantation of left ventricular assist devices (LVADs) as a bridge to transplant or as destination therapy is increasing. The selection of suitable patients and outcome assessment belong to the key challenges. Mortality has traditionally been a focus of research in this field, but literature on quality of life is very limited. This study aimed to identify perioperative factors influencing patients' life as measured by days alive and out of hospital (DAOH) in the first year after LVAD implantation.Methods and resultsThis retrospective single-centre cohort study screened 227 patients who underwent LVAD implantation at the University Hospital Duesseldorf, Germany, between 2010 and 2020. First, the influence of 10 prespecified variables on DAOH was investigated by univariate analysis. Second, multivariate quantile regression was conducted including all factors with significant influence on DAOH in the univariate model. Additionally, the impact of all variables on 1 year mortality was investigated using Kaplan-Meier curves to oppose DAOH and mortality. In total, 221 patients were included into analysis. As pre-operative factors, chronic kidney disease (CKD), pre-operative mechanical circulatory support (pMCS), and Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) stadium < 3 were associated with lower DAOH at 1 year [CKD: 280 (155-322) vs. 230 (0-219), P = 0.0286; pMCS: 294 (155-325) vs. 243 (0-293), P = 0.0004; INTERMACS 1: 218 (0-293) vs. INTERMACS 2: 264 (6-320) vs. INTERMACS 3: 299 (228-325) vs. INTERMACS 4: 313 (247-332), P ≤ 0.0001]. Intra-operative additional implantation of a right ventricular assist device (RVAD) was also associated with lower DAOH [RVAD: 290 (160-325) vs. 174 (0-277), P ≤ 0.0001]. As post-operative values that were associated with lower DAOH, dialysis and tracheotomy could be identified [dialysis: 300 (252-326) vs. 186 (0-300), P ≤ 0.0001; tracheotomy: 292 (139-325) vs. 168 (0-269), P ≤ 0.0001]. Multivariate analysis revealed that all of these factors besides pMCS were independently associated with DAOH. According to Kaplan-Meier analysis, only post-operative dialysis was significantly associated with increased mortality at 1 year (survival: no dialysis 89.4% vs. dialysis 70.1%, hazard ratio: 0.56, 95% confidence interval: 0.33-0.94; P = 0.031).ConclusionsThe results of this study indicate that there can be a clear discrepancy between hard endpoints such as mortality and more patient-centred outcomes reflecting life impact. DAOH may relevantly contribute to a more comprehensive selection process and outcome assessment in LVAD patients.

Project description:Rationale & objectiveNearly half the patients with heart failure have chronic kidney disease. Implantation of a left ventricular assist device (LVAD) improves kidney function in some but not all patients, and lack of improvement is associated with worse outcomes. Preimplantation factors that predict change in kidney function after LVAD placement are not well described.Study designSingle-center observational study.Setting & participantsConsecutive patients undergoing LVAD implantation.Predictors48 diverse preimplantation variables including demographic, clinical, laboratory, hemodynamic, and echocardiographic variables.OutcomesThe primary outcome was change in estimated glomerular filtration rate (eGFR) at 1 month after implantation. Secondary outcomes included eGFR changes at 3, 6, and 12 months.Analytic approachUnivariable and multivariable linear regression.ResultsAmong 131 patients, average age was 60 ± 13 years, 83% were men, 47% had pre-existing chronic kidney disease, and mean preimplantation eGFR was 57 ± 23 mL/min/1.73 m2. At 1-month following LVAD implantation, eGFR improved in 98 (75%) patients. Variables associated with 1-month increases in eGFR were younger age, absence of diabetes mellitus (DM), use of inotropes, lower implantation eGFR, and higher implantation serum urea nitrogen, alanine aminotransferase, bilirubin, and creatinine levels. In multivariable models, younger age (β = 7.14 mL/min/1.73 m2 per SD; 95% CI, 3.17-11.10), lower eGFR (β = 7.72 mL/min/1.73 m2 per SD; 95% CI, 3.10-12.34), and absence of DM (β = 10.36 mL/min/1.73 m2; 95% CI, 2.99-17.74) were each independently associated with 1-month improvement in eGFR. Only younger age and lower eGFR were associated with improvements in eGFR at later months.LimitationsSingle-center study. Loss to follow-up from heart transplantation and death over duration of study.ConclusionsOnly younger age, lower eGFR, and absence of DM were associated with improvement in eGFR at 1 month. Thus, prediction of eGFR change at 1 month and beyond is limited by using preimplantation variables.
