Background Frailty is a clinically recognized syndrome of decreased physiological reserve. The heightened state of vulnerability in these patients confers a greater risk of adverse outcomes after even minor stressors. Our aim was to assess the prevalence and prognostic significance of the frailty phenotype in patients referred for heart transplantation. Methods Consecutive patients referred or on the waiting list for heart transplantation from March 2013 underwent frailty assessment. Frailty was defined as a positive response to 3 or more of the following 5 components: weak grip strength, slowed walking speed, poor appetite, physical inactivity, and exhaustion. In addition, markers of disease severity were obtained, and all patients underwent cognitive (Montreal Cognitive Assessment) and depression (Depression in Medical Illness-10) screening. Results One hundred twenty patients (83 men:37 women; age, 53 ± 12 years, range, 16-73 years; left ventricular ejection fraction, 27 ± 14%) underwent frailty assessment. Thirty-nine of 120 patients (33%) were assessed as frail. Frailty was associated with New York Heart Association class IV heart failure, lower body mass index, elevated intracardiac filling pressures, lower cardiac index, anemia, hypoalbuminemia, hyperbilirubinemia, cognitive impairment, and depression (all &rgr; < 0.05). Frailty was independent of age, sex, heart failure duration, left ventricular ejection fraction, or renal function. Frailty was an independent predictor of increased all-cause mortality: 1 year actuarial survival was 79 ± 5% in the nonfrail group compared with only 54 ± 9% for the frail group (P < 0.005). Conclusions Frailty is prevalent among patients with advanced symptomatic heart failure referred for heart transplantation and is associated with increased mortality.

BACKGROUND Health literacy (HL) is a major determinant of health outcomes; however, there are few studies exploring the role of HL among heart transplant recipients. The objectives of this study were to: (1) explore and compare the prevalence of inadequate HL among heart transplant recipients internationally; (2) determine the correlates of HL; and (3) assess the relationship between HL and health-related behaviors. METHODS A secondary analysis was conducted using data of the 1,365 adult patients from the BRIGHT study, an international multicenter, cross-sectional study that surveyed heart transplant recipients across 11 countries and 4 continents. Using the Subjective Health Literacy Screener, inadequate HL was operationalized as being confident in filling out medical forms none/a little/some of the time (HL score of 0 to 2). Correlates of HL were determined using backward stepwise logistic regression. The relationship between HL and the health-related behaviors were examined using hierarchical logistic regression. RESULTS Overall, 33.1% of the heart transplant recipients had inadequate HL. Lower education level (adjusted odds ratio [AOR] 0.24, p < 0.001), unemployment (AOR 0.69, p = 0.012) and country (residing in Brazil, AOR 0.25, p < 0.001) were shown to be associated with inadequate HL. Heart transplant recipients with adequate HL had higher odds of engaging in sufficient physical activity (AOR 1.6, p = 0.016). HL was not significantly associated with the other health behaviors. CONCLUSIONS Clinicians should recognize that almost one third of heart transplant participants have inadequate health literacy. Furthermore, they should adopt communication strategies that could mitigate the potential negative impact of inadequate HL.

Background We recently reported that frailty is independently predictive of increased mortality in patients with advanced heart failure referred for heart transplantation (HTx). The aim of this study was to assess the impact of frailty on short-term outcomes after bridge-to-transplant ventricular assist device (BTT-VAD) implantation and/or HTx and to determine if frailty is reversible after these procedures. Methods Between August 2013 and August 2016, 100 of 126 consecutive patients underwent frailty assessment using Fried’s Frailty Phenotype before surgical intervention: 40 (21 nonfrail, 19 frail) BTT-VAD and 77 (60 nonfrail, 17 frail) HTx—including 17 of the 40 BTT-VAD supported patients. Postprocedural survival, intubation time, intensive care unit, and hospital length of stay were compared between frail and nonfrail groups. Twenty-six frail patients were reassessed at 2 months or longer postintervention. Results Frail patients had lower survival (63 ± 10% vs 94 ± 3% at 1 year, P = 0.012) and experienced significantly longer intensive care unit (11 vs 5 days, P = 0.002) and hospital (49 vs 25 days, P = 0.003) length of stay after surgical intervention compared with nonfrail patients. Twelve of 13 frail patients improved their frailty score after VAD (4.0 ± 0.8 to 1.4 ± 1.1, P < 0.001) and 12 of 13 frail patients improved their frailty score after HTx (3.2 ± 0.4 to 0.9 ± 0.9, P < 0.001). Handgrip strength and depression improved postintervention. Only a slight improvement in cognitive function was seen postintervention. Conclusions Frail patients with advanced heart failure experience increased mortality and morbidity after surgical intervention with BTT-VAD or HTx. Among those who survive frailty is partly or completely reversible underscoring the importance of considering this factor as a dynamic not fixed entity.

Objectives The objectives of this study were to: (1) explore the proportion of HTx centers that have a multidisciplinary team and (2) assess the relationship between multidisciplinarity and the level of chronic illness management (CIM). Background The International Society for Heart and Lung Transplantation (ISHLT) recommends a multidisciplinary approach in heart transplant (HTx) follow‐up care but little is known regarding the proportion of HTx centers that meet this recommendation and the impact on patient care. HTx centers with a multidisciplinary team may offer higher levels of CIM, a care model that has the potential to improve outcomes after HTx. Methods We conducted a secondary analysis of the BRIGHT study, a cross‐sectional study in 11 countries. Multidisciplinarity in the 36 HTx centers was assessed through HTx director reports and was defined as having a team that was composed of physician(s), nurse(s), and another healthcare professional (either a social worker, psychiatrist, psychologist, pharmacist, dietician, physical therapist, or occupational therapist). CIM was assessed with the Patient Assessment of Chronic Illness Care (PACIC). Multiple linear regression assessed the relationship between multidisciplinarity and the level of CIM. Results Twenty‐nine (80.6%) of the HTx centers had a multidisciplinary team. Furthermore, multidisciplinarity was significantly associated with higher levels of CIM (&bgr; = 5.2, P = 0.042). Conclusion Majority of the HTx centers follows the ISHLT recommendation for a multidisciplinary approach. Multidisciplinarity was associated with CIM and point toward a structural factor that needs to be in place for moving toward CIM.

Background. Frailty contributes to increased morbidity and mortality in patients referred for and undergoing lung transplantation (LTX). &e study aim was to determine if frailty is reversible after LTX in those classified as frail at LTX evaluation. Methods. Consecutive LTX recipients were included. All patients underwent modified physical frailty assessment during LTX evaluation. For patients assessed as frail, frailty was reassessed on completion of the post-LTX rehabilitation program. Frailty was defined by the presence of ≥ 3 domains of the modified Fried Frailty Phenotype (mFFP). Results. We performed 166 lung transplants (frail patients, n� 27, 16%). Eighteen of the 27 frail patients have undergone frailty reassessment. Eight frail patients died, and one interstate recipient did not return for reassessment. In the 18 (66%) patients reassessed, there was an overall reduction in their frailty score post-LTX ((3.4± 0.6 to 1.0± 0.7), p< 0.001) with 17/18 (94%) no longer classified as frail. Improvements were seen in the following frailty domains: exhaustion, mobility, appetite, and activity. Handgrip strength did not improve posttransplant. Conclusions. Physical frailty was largely reversible following LTX, underscoring the importance of considering frailty a dynamic, not a fixed, entity. Further work is needed to identify those patients whose frailty is modifiable and establish specific interventions to improve frailty.
