Reexamining "psychosocial clearance": A procedural framework for psychosocial evaluation in liver transplantation

Psychosocial and "nonmedical" phenomena are commonly encountered in liver transplantation (LT) evaluations. They are simultaneously crucial decision-making factors and some of the most difficult and controversial clinical matters clinicians confront. Epidemiology, societal trends, and the preponderance of psychological and behavioral factors underpinning common end-stage liver diseases ensure that LT teams will continue to encounter highly complex psychosocial patient presentations. Psychosocial policies, practices, and opinions vary widely among clinicians and LT centers. Liver clinicians already report insufficient psychosocial expertise, which creates a large gap between the stark need for psychosocial expansion, improvement, and innovation in LT and the lack of accompanying guidance on how to achieve it. While the clinical domains of an LT psychosocial evaluation have been well-described, few articles analyze the procedures by which teams determine candidates' "psychosocial clearance" and no conceptual frameworks exist. This article proposes a framework of core domains of psychosocial evaluation procedures, common pitfalls, and practical improvement strategies.

Assessing reliability and validity of SIPAT and opportunities for improvement: A single-center cohort study

Psychosocial assessment is a standard component of patient evaluations for transplant candidacy. The Stanford Integrated Psychosocial Assessment for Transplant (SIPAT) is a widely used measure to assess psychosocial risk for transplant. However, there are questions regarding the SIPAT's reliability and validity. We examined the SIPAT's psychometric performance and its impact on equitable access to transplant in a diverse cohort of 2825 patients seeking liver transplantation between 2014 and 2021 at an urban transplant center. The SIPAT demonstrated good internal consistency reliability at the overall score [Cronbach's α = 0.85, 95% CI (0.83, 0.86)] and domain levels (0.80 > α > 0.70). There was mixed support for structural validity, with poor overall model fit in confirmatory factor analysis and 50% of questions achieving the 0.70-factor loadings threshold. Adjusting for sociodemographic variables, the odds of not being waitlisted for psychosocial reasons were three times higher for patients with Medicaid insurance than patients with private insurance [OR 3.24, 95% CI (2.09, 4.99)] or Medicare [OR 2.89, 95% CI (1.84, 4.53)], mediated by higher SIPAT scores. Black patients had nearly twice the odds of White patients [OR 1.88, 95% CI (1.20, 2.91)], partially mediated by higher social support domain scores. Patients with Medicaid, non-White patients, and those without a college degree scored significantly higher on collinear questions, disproportionately contributing to higher SIPAT scores. The SIPAT did not perform equally across insurance type, race/ethnicity, and education groups, with the lowest subgroup validity associated with patient readiness and psychopathology domains. The SIPAT should be interpreted with caution, especially as a composite score. Future studies should examine validity in other populations.

High level of psychosocial adjustment in patients on ongoing ventricular assist device support in the years one to three after VAD implantation-A national multi-center Study

BACKGROUND

Advanced heart failure therapies such as durable ventricular assist device (VAD) support require psychosocial adjustment for those affected. Since VAD implantation has become an established treatment strategy, a focus on psychosocial factors is needed.

OBJECTIVES

To investigate the construct of psychosocial adjustment and to further understand the role of social support.

METHODS

In a nation-wide, multi-center, cross-sectional study, we recruited 393 participants with ongoing VAD support (3mts-3yrs on device; clinicaltrials.gov ID: NCT04234230). Patient demographics, psychosocial adjustment (perceived social support, anxiety, depression, and quality of life), and major adverse events (thromboembolic events, bleeding, driveline infections) were assessed.

RESULTS

Overall, 85.8 % of the sample were male; mean age was 58.3 years (range 18-85). The majority of the sample (89.3 %) reported normal to high perceived social support. Participants expressed symptoms of anxiety within the normal range (M=6.0±3.9), mildly elevated depressive symptoms (HADS: M=7.6±2.9; PHQ-9: M=6.2±4.7), and good quality of life (KCCQ: M=65.3±17.9). Higher perceived social support was associated with lower levels of anxiety and depression, and higher levels of quality of life within our sample (all p<0.001). Driveline infection was the most prevalent adverse event (0.304 infections per person-years [32.6 % of patients]). Binary logistic regression models did not identify significant associations for the occurrence of adverse events and variables of psychosocial adjustment.

CONCLUSION

Our sample perceived high levels of psychosocial adjustment. High perceived social support was associated with better outcomes in levels of anxiety, depression, and quality of life, demonstrating potential for the future development and evaluation of targeted multi-professional social support interventions including peer- and caregiver support.

When all Else Fails, Try This: The HeartMate III Left Ventricle Assist Device

Heart failure (HF) is a progressive disease. It is estimated that more than 250,000 patients suffer from advanced HF with reduced ejection fraction refractory to medical therapy. With limited donor pool for heart transplant, continue flow left ventricle assist device (LVAD) is a lifesaving treatment option for patients with advanced HF. This review will provide an update on indications, contraindications, and associated adverse events for LVAD support with a summary of the current outcomes data.

Multidisciplinary Care in Heart Failure Services

The American College of Cardiology/American Heart Association/Heart Failure Society of American 2022 guidelines for heart failure (HF) recommend a multidisciplinary team approach for patients with HF. The multidisciplinary HF team-based approach decreases the hospitalization rate for HF and health care costs and improves adherence to self-care and the use of guideline-directed medical therapy. This article proposes the optimal multidisciplinary team structure and each team member's delineated role to achieve institutional goals and metrics for HF care. The proposed HF-specific multidisciplinary team comprises cardiologists, surgeons, advanced practice providers, clinical pharmacists, specialty nurses, dieticians, physical therapists, psychologists, social workers, immunologists, and palliative care clinicians. A standardized multidisciplinary HF team-based approach should be incorporated to optimize the structure, minimize the redundancy of clinical responsibilities among team members, and improve clinical outcomes and patient satisfaction in their HF care.

Reproductive health after thoracic transplantation: An ISHLT expert consensus statement

Pregnancy after thoracic organ transplantation is feasible for select individuals but requires multidisciplinary subspecialty care. Key components for a successful pregnancy after lung or heart transplantation include preconception and contraceptive planning, thorough risk stratification, optimization of maternal comorbidities and fetal health through careful monitoring, and open communication with shared decision-making. The goal of this consensus statement is to summarize the current evidence and provide guidance surrounding preconception counseling, patient risk assessment, medical management, maternal and fetal outcomes, obstetric management, and pharmacologic considerations.

The Intersection of Aging and Lung Transplantation: its Impact on Transplant Evaluation, Outcomes, and Clinical Care

Purpose

Older adults (age ≥ 65 years) are the fastest growing age group undergoing lung transplantation. Further, international consensus document for the selection of lung transplant candidates no longer suggest a fixed upper age limit. Although carefully selected older adults can derive great benefit, understanding which older adults will do well after transplant with improved survival and health-related qualiy of life is key to informed decision-making. Herein, we review the epidemiology of aging in lung transplantation and its impact on outcomes, highlight selected physiological measures that may be informative when evaluating and managing older lung transplant patients, and identify directions for future research.

Recent Findings

In general, listing and transplanting older, sicker patients has contributed to worse clinical outcomes and greater healthcare use. Emerging evidence suggest that measures of physiological age, such as frailty, body composition, and neurocognitive and psychosocial function, may better identify risk for poor transplant outcomes than chronlogical age.

Summary

The evidence base to inform transplant decision-making and improvements in care for older adults is small but growing. Multipronged efforts at the intersection of aging and lung transplantation are needed to improve the clinical and patient centered outcomes for this large and growing cohort of patients. Future research should focus on identifying novel and ideally modifiable risk factors for poor outcomes specific to older adults, better approaches to measuring physiological aging (e.g., frailty, body composition, neurocognitive and psychosocial function), and the underlying mechanisms of physiological aging. Finally, interventions that can improve clinical and patient centered outcomes for older adults are needed.

Variation in Left Ventricular Assist Device Postdischarge Caregiver Requirements: Results From a Mixed-Methods Study With Equity Implications

BACKGROUND

Left ventricular assist device (LVAD) evaluation includes a psychosocial assessment, conducted by social workers (SWs) on the advanced heart failure multidisciplinary team. Postdischarge caregiving plans are central to psychosocial evaluation. Caregiving's relationship with LVAD outcomes is mixed, and testing patients' social resources may disadvantage those from historically undertreated groups. We describe variation in policies defining adequate caregiving plans post-LVAD implant and possible impacts on patients from marginalized groups.

METHODS

This was a 2-phase sequential mixed-methods study: (1) phase 1, survey of US-based LVAD SWs, describing assessment structure and policies guiding candidacy outcomes; and (2) phase 2, individual interviews with SWs to further describe how caregiving plan adequacy impacts LVAD candidacy.

RESULTS

Sixty-seven SWs returned surveys (rr=47%) from unique programs. Caregiving plan inadequacy (n=30) was the most common psychosocial dealbreaker. When asked what duration of caregiving is required, 23% indicated ≥3 months, 27% 4 to 12 weeks, and 30% <4 weeks. Two reported no duration requirement, 6 stated an indefinite 24/7 commitment was necessary. Across 22 interviews, SWs mirrored that caregiving plans were the most common psychosocial contraindication. How caregiving is operationalized varied. Participants voiced a tension between extended caregiving improving outcomes and the sense that some people of color, women, or low socioeconomic status patients struggle to meet stringent requirements.

CONCLUSIONS

Policies regarding adequate duration of 24/7 caregiving vary, but inadequate caregiving plans are the most common psychosocial contraindication. Participants worry about patients' ability to meet restrictive requirements, particularly from historically undertreated groups. This highlights a need to operationalize quality caregiving, standardize assessment, and support medically appropriate patients with strained social resources.

Cannabinoids and solid organ transplantation: Psychiatric perspectives and recommendations

Cannabinoid use in patients seeking solid organ transplantation (SOT) is an important and unsettled matter which all transplantation clinicians regularly encounter. It is also a multifaceted, interprofessional issue, difficult for any specialty alone to adequately address in a research article or during clinical care. Such uncertainty lends itself to bias for or against cannabinoid use accompanied by inconsistent policies and procedures. Scientific literature in SOT regarding cannabinoids often narrowly examines the issue and exists mostly in liver and kidney transplantation. Published recommendations from professional societies are mosaics of vagueness and specificity mirroring the ongoing dilemma. The cannabinoid information SOT clinicians need for clinical care may require data and perspectives from diverse medical literature which are rarely synthesized. SOT teams may not be adequately staffed or trained to address various neuropsychiatric cannabinoid effects and risks in patients. In this article, authors from US transplantation centers conduct a systematized review of the few existing studies regarding clinician perceptions, use rates, and clinical impact of cannabinoid use in SOT patients; collate representative professional society guidance on the topic; draw from diverse medical literature bases to detail facets of cannabinoid use in psychiatry and addiction pertinent to all transplantation clinicians; provide basic clinical and policy recommendations; and indicate areas of future study.

The History of Durable Left Ventricular Assist Devices and Comparison of Outcomes: HeartWare, HeartMate II, HeartMate 3, and the Future of Mechanical Circulatory Support

The utilization of left ventricular assist devices (LVADs) in end-stage heart failure has doubled in the past ten years and is bound to continue to increase. Since the first of these devices was approved in 1994, the technology has changed tremendously, and so has the medical and surgical management of these patients. In this review, we discuss the history of LVADs, evaluating survival and complications over time. We also aim to discuss practical aspects of the medical and surgical management of LVAD patients and future directions for outcome improvement in this population.

Smoking Mechanics and Impact on Smoking Cessation: Two Cases of Smoking Lapse Status Post Lung Transplantation

Background

Smoking behavior includes mechanisms taken on by persons to adjust for certain characteristic changes of cigarettes. However, as lung function declines due to lung-specific diseases, it is unclear how mechanical smoking behavior changes affect persons who smoke. We review two cases of patients who stopped smoking prior to and then subsequently resumed smoking after lung transplantation.

Methods

A retrospective review of two patients who were recipients of lung transplantation and sustained from cigarette usage prior to transplantation.

Results

Patient A was a 54-year-old woman who received a double lung transplant secondary to chronic obstructive pulmonary disease (COPD) in October 2017. She had stopped smoking cigarettes in July 2015 (FEV1 .56 L). Patient B was a 40-year-old man who received a double lung transplantation due to sarcoidosis in January 2015. He stopped smoking cigarettes in February 2012 (FEV1 1.15 L). Post-transplant, Patient A resumed smoking on March 2018 where her FEV1 was at 2.12 L (5 months post-transplantation), and Patient B resumed smoking in April 2017 where his FEV1 was 2.37 L (26 months post-transplantation).

Conclusion

We report on two patients who resumed smoking after lung transplantation. While variations of smoking mechanics have been identified as a function of nicotine yield and type of cigarette, it lung mechanics may play a role in active smoking as well. Therefore, proper screening for tobacco usage post-lung transplantation should be considered a priority in order to preserve transplanted lungs.

Psychosocial Risk and Health Behaviors as Predictors of Clinical Events in Patients Wait-Listed for a New Heart: Results from 7 Years of Follow-Up

We examined the long-term relationship of psychosocial risk and health behaviors on clinical events in patients awaiting heart transplantation (HTx). Psychosocial characteristics (e.g., depression), health behaviors (e.g., dietary habits, smoking), medical factors (e.g., creatinine), and demographics (e.g., age, sex) were collected at the time of listing in 318 patients (82% male, mean age = 53 years) enrolled in the Waiting for a New Heart Study. Clinical events were death/delisting due to deterioration, high-urgency status transplantation (HU-HTx), elective transplantation, and delisting due to clinical improvement. Within 7 years of follow-up, 92 patients died or were delisted due to deterioration, 121 received HU-HTx, 43 received elective transplantation, and 39 were delisted due to improvement. Adjusting for demographic and medical characteristics, the results indicated that frequent consumption of healthy foods (i.e., foods high in unsaturated fats) and being physically active increased the likelihood of delisting due improvement, while smoking and depressive symptoms were related to death/delisting due to clinical deterioration while awaiting HTx. In conclusion, psychosocial and behavioral characteristics are clearly associated with clinical outcomes in this population. Interventions that target psychosocial risk, smoking, dietary habits, and physical activity may be beneficial for patients with advanced heart failure waiting for a cardiac transplant.

The Year in Cardiothoracic Transplant Anesthesia: Selected Highlights From 2020 Part I - Lung Transplantation

This special article focuses on the highlights in cardiothoracic transplantation literature in the year 2020. Part I encompasses the recent literature on lung transplantation, including the advances in preoperative assessment and optimization, donor management, including the use of ex-vivo lung perfusion, recipient management, including those who have been infected with coronavirus disease 2019, updates on the perioperative management, including the use of extracorporeal membrane oxygenation, and long-term outcomes.

Sleep quality, depressive symptoms, and transplant outcomes: Follow-up analyses from the ADAPT prospective pilot study

BACKGROUND

Previous studies suggested that depressive symptoms and sleep quality may be important for long-term clinical outcomes following cardiothoracic transplant. Few studies, however, have systematically examined objective markers of these behavioral factors among ambulatory transplant recipients, or their association with clinical outcomes.

METHODS

We examined sleep quality and depressive symptoms with subsequent clinical outcomes (hospitalizations and death) in a sample of 66 lung or heart transplant recipients using a single-center, prospective cohort study. Recipients were assessed at approximately 6 months post-transplant and completed one week of actigraphy assessment to examine sleep quality and self-report measures of mood (Centers for Epidemiologic Studies of Depression [CESD]). Recipients were followed for clinical outcomes.

RESULTS

At 6-months following transplantation, recipients spent the majority of daytime activity at a sedentary level (61% of daily activity [SD = 10]) and elevated depressive symptoms were common (subclinical = 17%, mild = 12%, or moderate = 8%). Over a median follow-up of 4.5 years (IQR = 0.9, 5.1), 51 participants (77%) had at least one unplanned hospitalization and 11 (17%) participants died. In addition, sleep efficiency measurements suggested that a subset of participants exhibited suboptimal sleep (mean efficiency = 87% [SD = 7]). Poorer sleep quality, indexed by lower sleep efficiency and greater sleep fragmentation, was associated with greater depressive symptoms (r's = 0.37-0.50, P < .01). Better sleep quality at 6-months (HR = 0.75 [0.60, 0.95], P = .015), including sleep efficiency (HR = 0.74 [0.56, 0.99], P = .041) and sleep fragmentation (HR = 0.71 [0.53, 0.95], P = .020) were associated with lower risk of hospitalization or death. Compared with individuals without elevated depressive symptoms or sleep difficulties, individuals with either factor (HR = 1.72 [1.05, 2.81], P = .031) or both factors (HR = 2.37 [1.35, 4.18], P = .003) exhibited greater risk of clinical events in adjusted analyses.

CONCLUSIONS

Sleep quality is associated with depressive symptoms among cardiothoracic transplant recipients and enhances the prognostic association between biobehavioral risk factors and clinical outcomes.

Patient names for mechanical circulatory support devices: Developing emotional insights

BACKGROUND

Patients with mechanical circulatory support devices regularly experience positive and negative emotions which are reinforced through interactions with their device. We explored emotional relationships between patients and their MCS devices through the names they assign to those devices.

OBJECTIVES

We sought to characterise device naming and suggest future developments which might capitalise on the naming phenomenon to improve patient wellbeing.

METHODS

Qualitative online ethnography extracted comments on device names and emotions from a social media group. Thematic analysis grouped the comments according to their explicit or implied emotions, and their potential consequences for designing future MCS treatment.

RESULTS

Thematic analysis identified 28 codes to characterise the names, from which we inferred 4 main themes for proposed emotional relationships. They centred on humour, coping, improving acceptance for family and friends, and reclaiming agency.

CONCLUSION

We suggest that by deliberately considering these factors in future research and development, clinicians and device manufacturers have scope to improve patient wellbeing.

The relation between psychological distress and medication adherence in lung transplant candidates and recipients: A cross-sectional study

AIMS AND OBJECTIVES

To explore the prevalence of psychological distress such as anxiety, depression and post-traumatic stress disorder and its associations with medication adherence in lung transplant patients.

BACKGROUND

Psychological distress after lung transplantation may impact clinical outcomes by associated behaviours such as non-adherence to medication. Evidence about the relation between psychological distress and medication adherence in lung transplant patients is limited and not well explained.

DESIGN AND METHODS

We conducted a single-centre study with a cross-sectional design in 73 lung transplant candidates and 116 recipients. Questionnaires were the Brief Symptom Inventory, Impact of Event Scale and Basel Assessment of Adherence to Immunosuppressive Medications Scale. The STROBE checklist was monitored.

RESULTS

In candidates, 39.7% reported (sub)clinical symptoms of depression, in recipients this was 21.6%. We observed suicidal ideation in recipients (8.6%), and candidates (5.5%). The prevalence of (sub)clinical symptoms of anxiety was 38.3% in candidates and 33.7% in recipients. After lung transplantation, 12% of the recipients reported clinical symptoms of PTSD related to the transplantation. Symptoms of anxiety and medication adherence were significantly and positively related in transplant recipients. We found no association between depressive or post-traumatic stress symptoms, and medication adherence.

CONCLUSIONS

In lung transplant patients, we found a high prevalence of symptoms of depression and anxiety. Recipients had high levels of post-traumatic stress symptoms related to the transplantation. The prevalence of suicidal ideation was unexpectedly high in recipients. After lung transplantation, higher levels of anxiety were related to better medication adherence. We propose that LTX recipients are very anxious to develop dyspnoea and therefore take their medication more conscientiously.

RELEVANCE TO CLINICAL PRACTICE

The clinical nurse specialist can play a key role in identifying and addressing psychological and behavioural problems. More prospective research on the role of anxiety and dyspnoea in lung transplant recipients is recommended.

Frailty and aging-associated syndromes in lung transplant candidates and recipients

Many lung transplant candidates and recipients are older and frailer compared to previous eras. Older patients are at increased risk for pre- and posttransplant mortality, but this risk is not explained by numerical age alone. This manuscript represents the product of the American Society of Transplantation (AST) conference on frailty. Experts in the field reviewed the latest published research on assessment of elderly and frail lung transplant candidates. Physical frailty, often defined as slowness, weakness, low physical activity, shrinking, and exhaustion, and frailty evaluation is an important tool for evaluation of age-associated dysfunction. Another approach is assessment by cumulative deficits, and both types of frailty are common in lung transplant candidates. Frailty is associated with death or delisting before transplant, and may be associated with posttransplant mortality. Sarcopenia, cognitive dysfunction, depression, and nutrition are other important components for patient evaluation. Aging-associated inflammation, telomere dysfunction, and adaptive immune system senescence may also contribute to frailty. Developing tools for frailty assessment and interventions holds promise for improving patient outcomes before and after lung transplantation.

The association of post-operative delirium with patient-reported outcomes and mortality after lung transplantation

Post-operative delirium after lung transplantation is common. Its associations with health-related quality of life (HRQL), depression, and mortality remains unknown. In 236 lung transplant recipients, HRQL and depressive symptoms were assessed as part of a structured survey battery before and after transplantation. Surveys included the Geriatric Depressive Scale (GDS) and Short Form 12 (SF12). Delirium was assessed throughout the post-operative intensive care unit (ICU) stay with Confusion Assessment Method for ICU. Delirium and mortality data were extracted from electronic medical records. We examined associations between delirium and changes in depressive symptoms and HRQL using linear mixed effects models and association between delirium and mortality with Cox-proportional hazard models. Post-operative delirium occurred in 34 participants (14%). Delirium was associated with attenuated improvements in SF12-PCS (difference ₋4.0; 95%CI: -7.4, -0.7) but not SF12-MCS (difference 2.2; 95%CI: -0.7,5.7) or GDS (difference ₋0.4; 95%CI: -1.5,0.7). Thirty-two participants died during the study period. Delirium was associated with increased adjusted hazard risk of mortality (HR 17.9, 95%CI: 4.4,72.5). Delirium after lung transplantation identifies a group at increased risk for poorer HRQL and death within the first post-operative year. Further studies should investigate potential causal links between delirium, and poorer HRQL and mortality risk after lung transplantation.

Psychosocial considerations in the assessment of hand transplant candidates: A single-center experience and brief literature review

Vascularized composite allograft, including hand transplantation (HT), has gained wider usage as a reconstructive treatment over the past 30 years. HT recipients face unique psychosocial challenges compared to their solid organ and/or bone marrow transplant counterparts. Accordingly, the psychosocial evaluation among HT candidates continues to evolve, leaving a lack of consensus as to the critical psychosocial domains and psychometric testing instruments to help evaluate individuals considering HT. The present manuscript describes the psychosocial evaluation process within the Duke HT program, which been contacted by 80 potential candidates since 2014. The Duke HT evaluation process incorporates a comprehensive psychosocial assessment within domains including personality, cognitive function, mood, behavioral adherence, social support, and substance use history, among others. Our experience underscores the potential utility of collecting thorough psychosocial evaluations, supplemented by psychometric test data, to comprehensively assess potential HT candidates.

Therapeutic Strategy for a Patient with Advanced Heart Failure and Schizophrenia Without Cardiac Replacement Therapies

We had a 58-year-old man with advanced heart failure and progressive end-organ dysfunction refractory to inotropes. Following detailed discussions, he decided not to receive ventricular assist device therapy considering his comorbidity of schizophrenia. A palliative care team initiated 2.5 mg of morphine together with low-dose anti-heart failure medications, which improved not only his heart failure symptoms but also the congestive heart failure itself. Aggressive commitments of the palliative care team might improve not only patients' quality of life but also advanced heart failure itself.

A systematic review of psychosocial design considerations for the next generation of mechanical circulatory support

BACKGROUND

Biomedical engineers are developing new mechanical circulatory support pumps. Clinicians are generating and analysing new evidence for their prescription and management. Industrial designers are generating usable solutions for wearable components and controllers. However, psychosocial considerations may be falling between the cracks of the three disciplines because of their multi-faceted nature.

OBJECTIVES

This article seeks to identify psychosocial needs raised in previous work, re-frame them as needs for future products and services, and discuss routes to solutions.

METHODS

SLR extracted 225 statements on psychosocial considerations from 42 included articles. 23 codes were inductively generated and applied to relevant datapoints. Codes were consolidated under 4 main themes and re-framed as solvable problems.

RESULTS

Identified themes: expanded remote care, improved multidisciplinary management tools, creating easier interactions; and extending patient engagement.

CONCLUSIONS

Design-driven methods have been used to solve analogous problems in other contexts and can address the identified psychosocial problems if implemented fully.

The Transplant Evaluation Rating Scale Predicts Clinical Outcomes 1 Year After Lung Transplantation: A Prospective Longitudinal Study

Objectives: It has been recommended that all candidates for lung transplantation undergo pre-transplant psychosocial evaluation for risk assessment. However, psychosocial issues are only important if they correlate with outcomes after transplantation. Methods: In this prospective study patients who were referred for lung transplantation from 2016 to 2018 (n = 352) at Hannover Medical School were evaluated using the Transplant Evaluation Rating Scale (TERS). Clinical outcomes included listing, and post-transplant outcomes including mortality, medical aspects such as lung allograft dysfunction, hospitalizations, and renal function, behavioral aspects such as BMI and adherence, and mental issues such as levels of depression, anxiety, and quality of life. TERS scores were divided into tertiles and, in addition, the impact of the two subscale scores-"defiance" and "emotional sensitivity"-was investigated. Results: Of the patients who were transplanted (n = 271) and were still alive (n = 251), 240 had already reached their 1-year assessment at the end of 2020 and were evaluated 1 year after the operation. A subgroup of 143 received an extended mental assessment. BMI, adherence scores, levels of anxiety, depression, and quality of life 1 year post-transplantation differed significantly between TERS tertiles with higher TERS scores predicting less favorable outcomes. The TERS subscale "defiance" was predictive of BMI and adherence whereas the TERS subscale "emotional sensitivity" was predictive of symptoms of anxiety and depression, and quality of life 1 year after transplantation. Patients in the lowest TERS tertile were more likely to having been listed and-as a trend-to having survived the first year after transplantation Conclusions: Our findings show that psychosocial factors as measured by TERS score are predictors of behavioral and mental outcomes 1 year after lung transplantation. The TERS allows us to focus on psychosocial risk factors that can be treated or minimized before or after transplantation.

The Utility of a Pre-Transplant Psychosocial Evaluation in Predicting Post-Liver Transplant Outcomes

BACKGROUND

There is insufficient evidence about the ability of pretransplant psychosocial evaluations to predict posttransplant outcomes. While standardized assessments were developed to increase predictive validity, it is unclear whether the risk scores they yield predict outcomes. We investigated if the Stanford Integrated Psychosocial Assessment for Transplantation (SIPAT), a scaling approach to those assessments, would have been a superior predictor than the standard psychosocial evaluation.

METHODS

In this retrospective study, medical records of 182 adult liver transplant recipients who were at least 1 year posttransplant and prescribed tacrolimus for immunosuppression were analyzed. Regression analyses predicted outcomes of interest, including immunosuppressant nonadherence and biopsy-proven rejection, obtained 1-year posttransplant to time of data collection. Nonadherence was determined using the medication level variability index (MLVI).

RESULTS

Approximately 49% of patients had MLVI > 2.5, suggestive of nonadherence, and 15% experienced rejection. SIPAT total score did not predict adherence either using the continuous (P = .70), or dichotimized score, above or below > 2.5 (P = .14), or rejection (P = 0.87). Using a SIPAT threshold (total score > 69) did not predict adherence (p = .16) nor was a superior predictor of the continuous adherence score (P = .45), MLVI > 2.5 (P = .42), or rejection (P = 0.49), than the standard evaluation.

CONCLUSION

Our findings suggest that the SIPAT is unable to predict 2 of the most important outcomes in this population, immunosuppressant adherence and rejection. Research efforts should attempt to evaluate the best manner to use psychosocial evaluations.

Pig-to-human heart transplantation: Who goes first?

Cardiac xenotransplantation has recently taken an important step towards clinical reality. In anticipation of the "first-in-human" heart xenotransplantation trial, we propose a set of patient characteristics that define potential candidates. Our premise is that, to be ethically justified, the risks posed by current state-of-the-art options must outweigh the anticipated risks of a pioneering xenotransplant procedure. Suitable candidates include patients who are at high immunologic risk because of sensitization to alloantigens, including those who have exhibited early onset or accelerated cardiac allograft vasculopathy. In addition, patients should be considered (1) for whom mechanical circulatory support would be prohibitively risky due to a hypercoagulable state, a contraindication to anticoagulation, or restrictive physiology; (2) with severe biventricular dysfunction predicting unsuccessful univentricular left heart support; and (3) adults with complex congenital heart disease. In conclusion, because the published preclinical benchmark for clinical translation of heart xenotransplantation appears within reach, carefully and deliberately defining appropriate trial participants is timely as the basis for ethical clinical trial design.

Incorporating patient and caregiver feedback into lung transplant referral guidelines for individuals with cystic fibrosis-Preliminary findings from a novel paradigm

BACKGROUND

Lung transplantation is a common therapeutic option for individuals with cystic fibrosis (CF) and advanced lung disease, yet many individuals with CF are not appropriately referred for evaluation. The present study sought to enhance CF transplant referral guidelines by integrating patient-centered input to identify possible psychosocial barriers contributing to suboptimal referral for appropriate CF transplant candidates.

METHODS

As a component of developing the Cystic Fibrosis Foundation (CFF) Lung Transplant Referral Consensus Guidelines, we convened a focus group of lung transplant recipients with CF and two spouses of CF recipients. Each session involved standardized approaches to elicit qualitative, thematic content.

RESULTS

CF patients and caregivers characterized five areas for improvement, which were integrated into formal CFF referral guidelines. These included (a) timing of transplant discussion with CF providers, (b) accuracy of transplant-related knowledge and expectations, (c) stigma associated with the need for transplantation, (d) treatment team transition issues, and (e) social support and mental health concerns. Earlier introduction of transplant, greater details regarding manageable aspects of treatment, and greater provision of social support were all associated with better psychosocial experiences.

CONCLUSIONS

Integrating patient-centered input into guideline development yielded important and previously unknown psychosocial barriers contributing to suboptimal transplant referral.

Permanent Implantable Cardiac Support Systems

BACKGROUND

Nearly 1000 permanent ventricular assist devices (VADs) are implanted in patients with severe congestive heart failure in Germany each year. VADs are miniaturized centrifugal pumps that generate continuous blood flow; they are powered and controlled through a cable that passes through the skin. Para- corporeal systems are only rarely implanted, usually in children.

METHODS

In this selective review of the literature, including guidelines and registry data, we discuss the indications, therapeutic effects, and complications of permanently implantable cardiac support systems.

RESULTS

The optimal time for VAD implantation cannot be precisely defined. A comparative assessment of the various available systems is not possible, as no randomized trials have been performed on this topic. Registry data indicate that 69% to 81% of patients survive one year after VAD implantation, which is signifi- cantly better than the natural course of (conservatively treated) severe congestive heart failure. The distance patients are able to walk is 129 to 220 m longer at six months, depending on the system implanted. Scores on the EQ-5D health status questionnaire are 28 to 37 points better at six months. The potential severe compli- cations include infection, right-heart failure, hemorrhage, pump thrombosis, stroke, and death.

CONCLUSION

A VAD system can be implanted as an alternative to cardiac transplan- tation or as a bridging treatment until the patient can be listed for transplantation and receive the transplant. Because of the organ s , only a minority of VAD patients ever receive a transplant.

Coping Patterns and Emotional Distress in Patients With Chronic Obstructive Lung Disease Who Are Undergoing Lung Transplant Evaluation

OBJECTIVES

Living with severe lung disease like chronic obstructive pulmonary disease (COPD) is a very stressful situation. The way patients cope may impact their symptoms of anxiety and depression and physical function as well. We studied how ways of coping are associated with levels of emotional distress and lung function in patients with COPD being evaluated for lung transplantation.

METHODS

Sixty-five (mean age 57 years, 46% females) patients completed the General Health Questionnaire-30 (GHQ-30) assessing emotional distress and the Ways of Coping Questionnaire. Measurements of lung function and 6-minute walk test were included.

RESULTS

Seventeen (26%) patients had elevated emotional distress. Logistic regression of chronic GHQ score with gender, age, body mass index, lung function, and coping scales as covariates showed that escape avoidance and self-controlling coping and forced vital lung capacity were significantly associated with high emotional distress. Odds ratio of emotional distress increased with 5.2 per tertile (P = .011) in escape avoidance coping score. Moreover, we revealed that emotionally distressed patients cope with their current situation by refusing to believe the current situation and taking their distress out on other people.

CONCLUSION

Among patients with COPD, a high level of emotional distress was uniquely associated with escape-avoidance coping and lung function. Future work should ascertain whether coping style predicts distress or whether distress increases the use of escape-avoidance coping. Nevertheless, our findings indicate that if either element is present, health care professionals should be attentive to the need for interventions to improve patients' well-being.

Associations of depressive symptoms with outcomes in patients implanted with left ventricular assist devices

OBJECTIVE

We examined characteristics of depressive symptoms in patients who received left ventricular assist devices (LVAD) to assess their effects on negative outcomes post-implantation.

METHODS

We retrospectively identified 203 adults with pre-operative PHQ-9 scores who underwent LVAD placement as bridge to transplant (BTT) or destination therapy (DT). We analyzed effects of PHQ-9 total, somatic, and cognitive/affective scores and proportion of patients with clinical depression on all-cause mortality, rehospitalization, major bleeding, and neurologic events post-implantation, controlling for demographics and other medical comorbidities.

RESULTS

Mean total PHQ-9 scores did not differ between 81 BTT and 122 DT patients (BTT 6.4 vs. DT 7.5, p = 0.12). A higher proportion of DT patients had clinical depression (BTT 22% vs. DT 39%, p = 0.015). Somatic symptoms accounted for three-quarters of total scores in both groups. PHQ-9 domains were not associated with negative outcomes post-implantation.

CONCLUSION

Depression severity did not differ based on implant strategy, but more DT patients had clinical depression. Somatic symptoms were the biggest contributor to depressive symptoms. Pre-implantation PHQ-9 scores were not associated with outcomes, possibly because depression was mild in both groups. Additional work is needed in LVAD patients to better characterize depressive symptoms and their unique effects on clinical course and well-being.

Psychosocial dimensions of hand transplantation: lessons learned from solid organ transplantation

PURPOSE OF REVIEW

The present review examines psychosocial factors emerging as predictive of clinical outcomes among solid organ transplant (SOT) recipients, with possible extensions to vascular composite allograft (VCA) and hand transplantation, in particular. The Chauvet Workgroup report and International Society of Heart and Lung Transplantation consensus guidelines are used to delineate areas of commonality between SOT and VCA, as well as unique features contributing to post-VCA psychosocial risk.

RECENT FINDINGS

Increasing evidence suggests that depression, cognitive function, and other posttransplant psychosocial factors consistently associate with clinical risk in SOT. However, the mechanisms precipitating these psychosocial risk factors are likely diverse in their cause, with large individual differences across SOT and VCA. Transdiagnostic dimensions may serve as mechanistic factors, increasing the risk of adverse clinical outcomes and suggesting potential treatment strategies for risk mitigation. Psychosocial dimensions including psychological flexibility, self-efficacy, and posttraumatic growth are discussed as potential contributory factors.

SUMMARY

Psychosocial factors hold importance in predicting posttransplant clinical outcomes. Emerging transdiagnostic factors may provide insight into mechanisms and potential treatments.
