Health-related quality of life of transplant recipients: a comparison between lung, kidney, heart, and liver recipients

Quality of life of patients after kidney transplant: ADHERE Brazil multicenter cross-sectional study

BACKGROUND

Quality of life (QoL) is a measure to evaluate kidney transplant (KT) results.

AIM

To describe the QoL profile in a larger sample of Brazilian patients who underwent KT according to age, sex, and access to KT.

METHODS

We conducted a secondary data analysis of the ADHERE BRAZIL multicenter cross-sectional study including 1105 patients from 20 centers, considering KT access region and transplant activity. QoL was assessed by the WHOQOL-BREF. Data was compared using Generalized Estimating Equations.

RESULTS

Overall, 58.5 % of the patients were men, mean age of 47.6 ± 12.6 years. The general QoL score was 81 ± 15.1, 58.6 ± 11.6 for physical, 65.5 ± 11.4 for psychological, 68.3 ± 17.1 for social relationships, and 64.2 ± 13.3 for environmental domain. Higher QoL scores were observed in men compared to women in three WHOQOL-BREF domains: psychological (OR:2.62; CI, 1.29 ̶ 3.95, p < 0.0001), social relationships (OR:3.21; CI, 1.2 ̶ 5.23, p = 0.002) and environmental (OR:3.79; CI:2.23 ̶ 5.35, p < 0.0001). Younger patients (18-44 years) had higher scores in the psychological (OR:-2.69; CI, -4.13 ̶ -1.25; p < 0.001; OR:-3.52; CI, -5.39 ̶ -1.66; p < 0.001) and social (OR:-3.46; CI, -5.64 ̶ -1.27; p = 0.002; OR:-7.17; CI, -10 ̶ -4.35; p < 0.0001) domains than older ones (45-59 and > 60 years, respectively). Patients from higher KT access region had higher scores in environmental domain (OR:3.53; CI, 0.28 ̶ 6.78; p = 0.033).

CONCLUSIONS

Featuring the results of KT under patient view, the physical and social relationships domains were the most and least affected, respectively. Lower QoL subgroups (females and age > 45 years) should be targeted in future multi-professional interventions.

Impact of Religious Affiliation on Clinical Outcomes in Liver Transplant Patients

While the impact of spirituality as it relates to quality of life post-liver transplant (LT) has been studied, there are limited data showing how religious affiliation impacts objective measures such as survival. The aim of the study is to investigate whether LT recipients who identified as having a religious affiliation had better clinical outcomes when compared to LT recipients who did not. Religious affiliation is obtained as part of general demographic information for patients within our institution (options of "choose not to disclose" and "no religious affiliation" are available). Subjects in this retrospective cohort study which conformed with the Declarations of Helsinki and Istanbul were separated into cohorts: LT recipients who self-reported religious affiliation and LT recipients who did not. All LT recipients between March 2007 and September 2018 who had available information regarding their reported religion were included. Excluded patients included those who received a multi-organ transplant, underwent re-transplantation, received a partial liver graft, and identified as agnostic. Outcomes included 30-day readmission, death, and the composite outcome of re-transplantation/death. In an unadjusted analysis of 378 patients, there were no statistically significant differences between the two groups for 30-day readmission (OR=1.15, P=0.71), death (HR=0.63, P=0.19), or re-transplantation/death (HR=0.90, P=0.75). In multivariable analysis, adjusting for age at transplant and hospital admittance status when called for transplant, results were similar. We found no statistically significant difference in the outcomes measured between patients with and without self-reported religious affiliation. Further studies into the role of participation in religious activity and the impact of engagement with a religious community should be conducted in the future.

Quality of life and its association with predictors in lung transplant recipients: a latent profile analysis

Backgrounds

Improving quality of life (QOL) is one of the main aims of lung transplantation (LTx). There is a need to identify those who have poor quality of life early. However, research addressing inter individual quality of life variability among them is lacking. This study aims to identify group patterns in quality of life among lung transplant recipients and examine the predictors associated with quality of life subgroups.

Methods

In total, 173 lung transplant recipients were recruited from one hospital in Guangdong Province between September 2022 and August 2023. They were assessed using the Lung Transplant Quality of Life scale (LT-QOL), Mindful Attention Awareness Scale (MAAS), Life Orientation Test-Revised scale (LOT-R), and Positive and Negative Affect Scale (PANAS). Latent profile analysis was used to identify QOL subtypes, and logistic regression analysis was used to examine the associations between latent profiles and sociodemographic and psychosocial characteristics.

Results

Two distinct QOL profiles were identified: "low HRQOL" profile [N = 53 (30.94%)] and "high HRQOL" profile [N = 120 (69.06%)]. Single lung transplant recipients, and patients who reported post-transplant infection, high levels of negative emotion or low levels of mindfulness and optimism were significantly correlated with the low QOL subgroup.

Conclusion

Using the domains of the LT-QOL scale, two profiles were identified among the lung transplant recipients. Our findings highlighted that targeted intervention should be developed based on the characteristics of each latent class, and timely attention must be paid to patients who have undergone single lung transplantation, have had a hospital readmission due to infection, exhibit low levels of optimism, low levels of mindfulness or high negative emotions.

Assessing quality of life in solid organ transplant recipients: A systematic review of the development, content, and quality of available condition- and transplant-specific patient-reported outcome measures

PURPOSE

We aimed to identify the condition- and transplant-specific patient-reported outcome measures (PROMs) available to measure quality of life (QoL) in solid organ transplant (SOT) recipients, examine their development and content, and critically appraise the quality of their measurement properties, to inform recommendations for clinical and research use.

METHODS

We systematically searched MEDLINE, Embase, CINAHL, PsycINFO, Cochrane CENTRAL, and Scopus from inception to 27th January 2023. Search hits were screened for eligibility by two independent reviewers; papers reporting the development and/or validation of condition- and transplant-specific PROMs measuring QoL in adult SOT recipients were considered eligible. We abstracted and synthesised data on PROM characteristics, development (item generation and/or reduction), and content (QoL dimensions). Quality appraisal and synthesis were informed by the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) guidelines, and included methodological and quality assessment of measurement properties, GRADE levels of evidence, feasibility and interpretability.

RESULTS

We identified 33 papers reporting 26 QoL PROMs validated in SOT recipients (kidney n = 10 PROMs; liver n = 6; lung n = 3; heart n = 2; pancreas n = 1; multiple organs n = 4). Patient discussions (n = 17 PROMs) and factor analysis (n = 11) were the most common item generation and reduction techniques used, respectively. All PROMs measured ≥3 of nine QoL dimensions (all measured emotional functioning); KDQoL-SF and NIDDK-QA measured all nine. Methodological quality was variable; no PROM had low evidence or better for all measurement properties. All PROMs were COSMIN recommendation category 'B', primarily because none had sufficient content validity.

CONCLUSIONS

There are many condition- and transplant-specific QoL PROMs validated in SOT recipients, particularly kidney. These findings can help inform PROM selection for clinicians and researchers. However, caution is required when adopting measures, due to the substantial heterogeneity in development, content, and quality. Each PROM has potential but requires further research to be recommendable. Greater consideration of patient and professional involvement in PROM development in this setting is needed to ensure sufficient content validity.

An initial exploration of fatigue as a predictor of quality of life in transplant athletes competing at national and international events

Supporting organ transplant recipients' quality of life after surgery continues to be of interest to health researchers and applied practitioners. However, literature and guidance on the factors linked to quality of life in transplant recipient athletes remains underreported. This study aimed to identify significant predictors of quality of life in an international sample of organ transplant recipient athletes (N = 99, Mage = 53 ± 14). Adopting a cross-sectional design, we collected the study data during the 2019 World Transplant Games which consisted of demographic items, health, and physical activity-related measures (i.e., task and ego orientation, fatigue severity, assessment of physical activity, physical activity enjoyment). Predictor variables were summarised into three categories: demographic factors, sport-related factors, and levels of fatigue with physical and mental quality of life functioning as the outcome variables. Hierarchical regression analyses exposed fatigue to exert a significant negative influence on both mental and physical quality of life perceptions explaining 49% and 64% of the variance in these variables respectively. Routine measurement and monitoring of transplant athletes' level of fatigue in sport settings are recommended due to the negative bearing on quality of life that may be a potential barrier to sport participation and enjoyment.

Health status of patients with liver transplantation by alcohol-related disease vs another etiology: A cohort study

AIM

To study the health status of a group of patients with liver transplantation by alcohol-related disease vs another etiology before and after the transplantation.

METHOD

Longitudinal cohort study of liver transplant patients from November 2019 to July 2022. Adult patients attended in the unit of transplantation of a hospital for a first liver transplant, both elective and urgent, were included. Patients who already had a transplanted organ and those who required liver re-transplantation in the first month after the first transplant were excluded. Sociodemographic and clinical variables, MELDNa, liver frailty index, emotional-behavioral effects of transplantation, level of anxiety and depression were collected. Pearson's chi-square, Student's t, Mann-Whitney U, and Wilcoxon sign tests were used for statistical analysis.

RESULTS

The sample was n = 67 liver transplant patients with a mean age of 56.37 years, 67.2% being men and 39% due to alcohol-related liver disease. 9% of all included patients were urgent transplants. Alcohol consumption was associated with older age, a high rate of liver frailty, and a non-active work situation. Alcoholic etiology correlated with increased concern during the first six months after liver transplantation.

CONCLUSION

There are differences in the health status between liver transplant patients for alcohol-related liver disease vs other etiology. Nurses must consider the etiology of liver disease to guide care and interventions throughout the transplant process.

Factors Affecting Anxiety of Kidney Transplant Recipients According to Donor Type: A Descriptive Study

PURPOSE

High anxiety among kidney transplant recipients has negative psychosocial consequences for health quality. This study aims to determine the risk factors that affect levels of anxiety in recipients of kidney transplants according to living and deceased donor types.

DESIGN

The study was conducted using a descriptive correlational research method.

METHODS

The study conducted research with 330 kidney transplant recipients (from 261 live and 69 cadaver donors) who agreed to participate between February and July 2019. Participants completed the State-Trait Anxiety Inventory, which assesses state and trait anxiety.

FINDINGS

Participants had low state anxiety and moderate trait anxiety scores. A statistically significant, positive, moderate correlation was found between state anxiety scale and trait anxiety scale mean scores of recipients of kidney transplants from both living and deceased donors. According to a regression analysis of trait anxiety scores of transplant recipients from living donors, positive independent risk factors for anxiety include kidney transplant recipients with a low income, receiving kidneys from male donors, drug noncompliance, sleep disorders, and mental problems.

CONCLUSIONS

Both kidney transplant recipients from living and deceased donors had low state anxiety and moderate trait anxiety. Nurses should develop effective intervention strategies that continue throughout life to reduce the anxiety of kidney transplant recipients.

Analysis of the impact of liver transplantation as a condition of health

AIM

To analyse the impact that liver transplantation has had on the patient as a condition of their health.

METHOD

A prospective study was carried out, the sample of which was made up of liver transplant patients at the Gregorio Marañón General University Hospital from November 2019 to August 2021. The hospital anxiety and depression scale, the Model for End-stage liver disease sodium and liver fragility index and the Transplant Effects Questionnaire Spanish were used. The data were analysed using descriptive statistics. The student's t-test was used for continuous variables and the chi-square test for categorical variables. For non-parametric samples, the Wilcoxon, Mann-Whitney U test and Kruskal-Wallis's sign were used.

RESULTS

The sample was made up of 60 patients with a mean age of 55.68 years, 70% being men. The mean anxiety and depression scores of the patients improved significantly after liver transplantation. The impact of physical health resulted that those patients with a higher Model for End-stage liver disease sodium were correlated with a greater feeling of guilt after transplantation. Furthermore, greater adherence to immunosuppressive treatment was directly correlated with greater disclosure and inversely with guilt, after transplantation.

CONCLUSION

Liver transplantation is a process that impacts the health of patients. Those patients who arrive at the transplant with a more deteriorated physical situation present a greater guilt after the transplant. This impact is inversely correlated with adherence to immunosuppressive treatment. Nurses should intervene in such patients to reduce the impact on adherence to treatment.

Ex-Vivo Preservation with the Organ Care System in High Risk Heart Transplantation

Objective: Ex vivo organ perfusion is an advanced preservation technique that allows graft assessment and extended ex situ intervals. We hypothesized that its properties might be especially beneficial for high-risk recipients and/or donors with extended criteria. Methods: We reviewed the outcomes of 119 consecutive heart transplant patients, which were divided into two groups: A (OCS) vs. B (conventional). Ex vivo organ perfusion was performed using the Organ Care System (OCS). Indications for OCS-usage were expected ischemic time of >4 h or >2 h plus given extended donor criteria. Results: Both groups included mostly redo cases (A: 89.7% vs. B: 78.4%; p = 0.121). Incidences of donors with previous cardiac arrest (%) (A: 32.4 vs. B: 22.2; p < 0.05) or LV-hypertrophy (%) (A: 19.1 vs. B: 8.3; p = 0.119) were also increased in Group A. Ex situ time (min) was significantly longer in Group A (A: 381 (74) vs. B: 228 (43); p < 0.05). Ventilation time (days) (A: 10.0 (19.9) vs. B: 24.3 (43.2); p = 0.057), postoperative need for ECLS (%) (A: 25.0 vs. B: 39.2; p = 0.112) and postoperative dialysis (chronic) (%) (A: 4.4 vs. B: 27.5; p < 0.001) were numerically better in the OCS group, without any difference in the occurrence of early graft rejection. The 30-d-survival (A: 92.4% vs. B: 90.2%; p = 0.745) and mid-term survival were statistically not different between both groups. Conclusions: OCS heart allowed safe transplantation of surgically complex recipients with excellent one-year outcomes, despite long preservation times and unfavourable donor characteristics. Furthermore, we observed trends towards decreased ventilation times and fewer ECLS treatments. In times of reduced organ availability and increasing recipient complexity, OCS heart is a valuable instrument that enables otherwise infeasible allocations and contributes to increase surgical safety.

The translation and validation of the Organ Transplant Symptom and Well-Being Instrument in China

To translate the Organ Transplant Symptom and Well-Being instrument (OTSWI) into Chinese and test the reliability and validity of the Chinese version. A total of 259 patients with organ transplants were recruited from The First Affiliated Hospital of China Medical University in Shenyang, from November 2020 to January 2021. Construct validity was evaluated using exploratory factor analysis (EFA) and reliability were assessed using test-retest reliability and internal consistency. The Cronbach's α of the Chinese version of the Organ Transplant Symptom and Well-being instrument was 0.93. EFA demonstrated that 80.785% of the total variance was explained by a seven-factor solution. The criterion validity of the SF-36 was -0.460 (p < .01), while the test-retest reliability was 0.710. The Chinese version of the OTSWI questionnaire is a valid and reliable instrument for assessing the quality of life of organ transplant patients for symptoms and well-being in China.

Impact of biliary complications on quality of life in live-donor liver transplant recipients

BACKGROUND

Despite significant advancements in liver transplantation (LT) surgical procedures and perioperative care, post-LT biliary complications (BCs) remain a significant source of morbidity, mortality, and graft failure. In addition, data are conflicting regarding the health-related quality of life (HRQoL) of LT recipients. Thus, the success of LT should be considered in terms of both the survival and recovery of HRQoL.

AIM

To assess the impact of BCs on the HRQoL of live-donor LT recipients (LDLT-Rs).

METHODS

We retrospectively analysed data for 25 LDLT-Rs who developed BCs post-LT between January 2011 and December 2016 at our institution. The Short Form 12 version 2 (SF 12v2) health survey was used to assess their HRQoL. We also included 25 LDLT-Rs without any post-LT complications as a control group.

RESULTS

The scores for HRQoL of LDLT-Rs who developed BCs were significantly higher than the norm-based scores in the domains of physical functioning (P = 0.003), role-physical (P < 0.001), bodily pain (P = 0.003), general health (P = 0.004), social functioning (P = 0.005), role-emotional (P < 0.001), and mental health (P < 0.001). No significant difference between the two groups regarding vitality was detected (P = 1.000). The LDLT-Rs with BCs had significantly lower scores than LDLT-Rs without BCs in all HRQoL domains (P < 0.001) and the mental (P < 0.001) and physical (P = 0.0002) component summary scores.

CONCLUSION

The development of BCs in LDLT-Rs causes a lower range of improvement in HRQoL.

Patient-Reported Outcomes in Cardiovascular Trials

Patient-reported outcomes (PROs) are reports of a person's health status that provide a global perspective of patient well-being. PROs can be classified into 4 primary domains: global, mental, physical, and social health. In this descriptive review, we focus on how PROs can be used in cardiac clinical trials, with an emphasis on cardiac surgical trials for patients with coronary heart disease and heart failure. We also highlight ongoing challenges and provide specific suggestions and novel opportunities to advance cardiac clinical trials. Current challenges include the long-term measurement of PROs in clinical trials beyond 1 year, inconsistency in the choice of the outcome measures among studies, and the lack of measurement of PROs across multiple domains. Opportunities for advancement include measuring PROs using consumer health informatics tools, including returning information back to participants in formats that they can understand using visualization. Future opportunities include quantifying cohort-specific minimal clinically important differences for PROs.

Does oral health-related quality of life of patients after solid organ transplantation indicate a response shift? Results of a systematic review

BACKGROUND

The physical oral health and dental behaviour of patients after solid organ transplantation (SOT) has repeatedly been reported as insufficient. The objective of this systematic review was to detect whether the oral health-related quality of life (OHRQoL) of patients after SOT is reduced compared to that of healthy individuals.

METHODS

A systematic literature search was performed by two independent individuals based on the PubMed, Web of Science and Scopus databases by using the following search terms: "transplantation" AND "oral health-related quality of life". The findings were checked to determine eligibility, whereby publication prior to 31 October 2020, examination of adult patients (age at least 18 years) with SOT, reporting of an OHRQoL outcome and full text in English language were the prerequisites for inclusion in the qualitative analysis. Quality appraisal of the included studies was performed using the Agency for Healthcare Research and Quality methodology checklist.

RESULTS

Seven of 25 studies that examined patients after kidney (3), heart (2), liver (1) and lung transplantation (1) were included. Four studies included healthy controls, and five studies included a cohort of patients before transplantation for comparison. Clinical oral health examinations were heterogeneous between groups. The majority of studies (5/7) applied the short form of the "Oral Health Impact Profile" (OHIP 14) to assess OHRQoL. The OHIP 14 values ranged between 1.7 and 8.9 across studies, indicating an unaffected or just slightly reduced OHRQoL. Only one study found better OHRQoL in patients after SOT compared to a group before SOT, and one study confirmed worse OHRQoL of SOT recipients compared to a healthy control. Only two studies revealed an association between OHRQoL and oral health parameters. Furthermore, two studies each found a relationship between OHRQoL and general health-related quality of life or disease-related parameters.

CONCLUSIONS

Patients after SOT show an unaffected or only slightly reduced OHRQoL, which was mainly independent of the insufficient oral status. This might indicate a shift in the perception threshold for oral diseases and conditions caused by the general health burden related to the SOT.

Deceased donor kidney transplant in a 70-year-old Jehovah's Witness patient: to transplant or not to transplant-a case report

While Jehovah's Witness (JW) patients refuse transfusions of blood or blood products, they are willing to accept renal allograft transplantation. We describe here a case of what we believe is the oldest (a 70-year-old) JW candidate to undergo a deceased donor kidney transplant reported in the literature. Prior to transplantation, discussions ensued amongst the multidisciplinary transplant team, weighing the potential benefits vs. risks of performing a kidney transplant on this patient due to her refusal (due to religion) to accept any blood transfusions or blood products combined with her advanced age and having longstanding insulin-dependent, type 2 diabetes mellitus with extensive peripheral vascular disease. Preoperatively, we believed that the odds were in favor of performing the kidney transplant safely without the need for any blood product usage. However, her post-operative course was complicated by severe anemia, which developed by post-transplant day 4. The anemia incapacitated the patient's physical and psychological state, creating medical, social and financial burdens on the patient, family, medical team and hospital. Both family and patient grew concerned about her overall condition. Blood transfusion was offered in order to improve her weakness and shortness of breath that developed due to the severe anemia, but the patient (along with her family) refused such treatment. During the 17 days of hospitalization, it was a continuous struggle between the transplant team, patient, and family for her to continue with the recovery process; at times we had even considered that performing the transplant had been a mistake. While organ transplantation can be performed safely in Jehovah's Witnesses, there are multiple factors seen in this particular case that warrant analyzing: (I) the potential use of stricter transplant exclusionary criteria, given the recipient's advanced age and preexisting co-morbidities, which likely increased her risk of developing severe anemia post-operatively, and (II) the recipient's emotional/psychological post-operative state of high anxiety, which developed while she was experiencing the severe anemia; in hindsight, her anxiety level may have been reduced if we had offered daily post-operative psychological counseling sessions. While the patient's allograft is currently doing well, we probably did not have strict enough criteria for proper selection of a JW candidate for kidney transplantation.

Understanding the Long-Term Impact of Living-Related Liver Transplantation on Youth and Young Adults and their Family

PURPOSE

The purpose of this mixed methods study was to better understand the long term impact of living-related liver donation (LRLD) on youth and young adult (YYA) recipients and their family.

DESIGN AND METHODS

Semistructured interviews were conducted with YYA, aged 11-18 years, who received a living donation from a parent. Interviews were audiotaped, transcribed, and analyzed to aggregate themes that represented the participants' views as live-liver recipients. An ethnographic process was conducted to understand the participants' social behavior. At interview, participants completed a demographics questionnaire and the Youth Quality of Life Instrument-Research Version (YQOL-R).

RESULTS

Thirteen adolescents were interviewed; six were re-interviewed as key informants. Three major categories were created from the data: Developing Identity, Redefining Family Relationships, Feeling Gratitude to Donors. The overarching theme was Resiliency. Findings from the YQOL-R showed no difference in overall scores or separate domains when compared with a reference population with no chronic illness.

CONCLUSION

Qualitative and quantitative data highlight the positive effect that LRLD can have on pediatric patients as they transition from childhood to adolescence to young adulthood.

PRACTICE IMPLICATIONS

As pediatric transplant centers in the United States soon mark 30 years of performing live-liver donation, recipients are becoming adults and understanding more clearly that the long-term effects of such donations will lead to improvements in future care.

Organ allocation in the age of the algorithm: avoiding futile transplantation - utility in allocation

PURPOSE OF REVIEW

This review describes and questions the evolution of allocation systems from local team decisions in the 20th century to patient-oriented allocation using complex algorithm predicting transplant benefit.

RECENT FINDINGS

The opening years of the 2000s have seen the implementation of prioritization scores aiming at increasing transparency and reducing waitlist mortality. The 2010s have underlined the necessity of drawing the upper limits of how sick a patient can be while still ensuring acceptable survival. More complex algorithms evaluating transplant benefit have been implemented in allocation systems to take this issue into account.

SUMMARY

Allocation algorithms are becoming more and more complex, integrating numerous parameters from both donor and recipient to achieve optimal matching. The limitations of implementing these complex algorithms are represented by the evermoving waiting list demography, geographic disparities between recipients and donors, team policy adaptation to rule changes, and implicit biases within the transplant community. Survival as the only metric by which to define benefit may be seen as restrictive; quality of life may be a fruitful measure for better defining benefit in organ transplantation in the future.
