Liver transplant recipients: individual, social, and environmental resources

Medication non-adherence among liver transplant recipients

PURPOSE OF REVIEW

We provide an overview of the recent evidence on the prevalence, risk factors, and consequences of medication non-adherence (NA) in liver transplant (LT) recipients.

RECENT FINDINGS

NA in LT is associated with socio-demographic and medication-related factors, low social support, and poor health literacy. Patient-reported adherence is one of the most common methods to measure NA using validated assessments; immunosuppression (IS) drug levels and electronic monitoring may also be used. Simplification of IS regimens such as the conversion from twice daily to once daily has been shown to be safe, effective, and improves adherence. Relatively few studies have prospectively investigated NA predictors or interventions to reduce NA in LT.

SUMMARY

Medication non-adherence is a multi-faceted issue that is common among LT recipients and associated with adverse outcomes. NA in LT recipients warrants further study as only a few interventions have been published focused on reducing NA in LT.

Assessment and enrolment process for liver transplantation: nursing management through quality indicators

Objective

To establish, measure and analyze quality indicators in the evaluation and enrolment process of patients in a liver transplant program.

Methods

A quantitative and non-experimental research, with data collected from the database of a liver transplant program, from September 2012 to September 2014. Descriptive statistics were used to analyze the quality indicators identified.

Results

We analyzed 1,311 visits in the transplant outpatient clinic, most males (66.7%), white (65.1%), mean age of 53 (±12.5) years, from the Southeastern Region (91.2%), and from the State of São Paulo (80.8%). The indicators measured were efficiency of patient admission process (54.8%), efficiency of evaluation of transplant indication (39.9%), efficacy of treatment of patients seen in the program (21.8%), and waiting time to inclusion in the waiting list, median of 84 days (36-142).

Conclusion

The quality indicators analyzed in this study enabled a quantitative view of the process, facilitating management of results and benchmarking with other transplant centers. Continuous monitoring can optimize resource allocation and planning of services in patient's admission process.

Is social support associated with post-transplant medication adherence and outcomes? A systematic review and meta-analysis

Although social support is used to determine transplant eligibility, the relationship between social support, medication adherence, and survival among transplant recipients remains unclear. We estimated the relationship between social support and post-transplant medication adherence and outcomes using 10 electronic databases from inception to January 2016. Study quality was assessed and all review stages were conducted independently by 2 reviewers. Systematic review and meta-analysis were conducted. Thirty-two studies (9102 participants) met inclusion criteria: 21 assessed medication adherence (5197 participants), and 13 assessed clinical outcomes (3905 participants). Among high quality studies, neither social support nor marital status was predictive of medication adherence or post-transplant outcomes. Social support was not associated with medication adherence. It was associated with superior post-transplant outcomes, but the relationship was not significant among high quality studies. Compared to unmarried recipients, married recipients were more likely to adhere to medication post-transplant, but this relationship was not significant among high quality studies. Marital status was not significantly associated with transplant success. Social support is weakly and inconsistently associated with post-transplant adherence and outcomes. Larger prospective studies using consistent and validated measures are needed to justify the use of inadequate social support as a contraindication to transplantation.

Coping Strategies in Liver Transplant Recipients and Caregivers According to Patient Posttraumatic Growth

The purpose of this study was to analyze the differences in coping strategies employed by liver transplant recipients and their family members according to patient posttraumatic growth. Two matched groups of 214 liver transplant recipients and 214 family members were selected. The Posttraumatic Growth Inventory and Brief COPE were used. The most relevant results were: (1) Interactive effects in active coping, support (instrumental and emotional) and acceptance strategies, which were all used more by patients with higher growth levels, while their family members showed no differences in use of these strategies by patient growth level. Furthermore, while a low level of patient growth did not mark differences between them and their caregivers, a high level did, patients employing more active coping and support (instrumental and emotional), (2) In both groups a high level of patient growth was associated with more use of positive reframing and denial than a low one, and (3) Self-blame was employed by patients more than by their caregivers. It was concluded that a high level of posttraumatic growth in liver transplant recipients is associated with more use of healthy coping strategies, basically active coping, instrumental support, and emotional support.

Quality of life in liver transplant recipients and the influence of sociodemographic factors

Abstract OBJECTIVE To verify the influence of sociodemographic factors on the quality of life of patients after liver transplant. METHOD Cross-sectional study with 150 patients who underwent liver transplant at a referral center. A sociodemographic instrument and the Liver Disease Quality of Life questionnaire were applied. The analysis of variance (ANOVA) was performed, as well as multiple comparisons by the Tukey test and Games-Howell tests when p <0.05. RESULTS Old age had influence on domains of symptoms of liver disease (p = 0.049), sleep (p = 0.023) and sexual function (p = 0.03). Men showed better significant mean values than women for the loneliness dimension (p = 0.037). Patients with higher educational level had higher values for the domain of stigma of liver disease (p = 0.014). There was interference of income in the domains of quality of social interaction (p = 0.033) and stigma of the disease (p = 0.046). CONCLUSION In half of the quality of life domains, there was influence of some sociodemographic variable.

Gravidade da doença hepática e qualidade de vida no transplante de fígado

Resumo Objetivo Analisar a influência da gravidade da doença hepática na qualidade de vida dos pacientes antes e depois do transplante de fígado. Métodos Estudo descritivo com 150 receptores de transplante hepático, maiores de 18 anos. A gravidade foi avaliada pelo Child e MELD e aplicado o Liver Disease Quality of Life. Foi utilizado teste t ou Mann-Whitney para comparação das médias dos domínios e ANOVA ou Kruskal-Wallis para comparação entre grupos. Resultados Antes do transplante, os pacientes com Child C obtiveram menores escores de qualidade de vida do que os com Child A. Pacientes com MELD menor ou igual a 15 tiveram aumento significativo das médias em 10 domínios, enquanto os pacientes com MELD superior a 15 tiveram aumento nos 12 domínios. Conclusão Houve influência negativa da gravidade pelo CTP na qualidade de vida antes do transplante. O MELD não interferiu significativamente nos resultados pós-transplante, mesmo com elevação das médias.

A multifaceted prospective memory intervention to improve medication adherence: design of a randomized control trial

Adherence to prescribed antihypertensive agents is critical because control of elevated blood pressure is the single most important way to prevent stroke and other end organ damage. Unfortunately, nonadherence remains a significant problem. Previous interventions designed to improve adherence have demonstrated only small benefits of strategies that target single facets such as understanding medication directions. The intervention described here is informed by prospective memory theory and performance of older adults in laboratory-based paradigms and uses a comprehensive, multifaceted approach to improve adherence. It incorporates multiple strategies designed to support key components of prospective remembering involved in taking medication. The intervention is delivered by nurses in the home with an education control group for comparison. Differences between groups in overall adherence following the intervention and 6 months later will be tested. Systolic and diastolic blood pressure levels also will be examined between groups and as they relate to adherence. Intra-individual regression is planned to examine change in adherence over time and its predictors. Finally, we will examine the association between executive function/working memory and adherence, predicting that adherence will be related to executive/working memory in the control group but not in the intervention group.

Pathways of psychosocial factors, stress, and health outcomes after liver transplantation

The impact of stress and individual factors on health outcomes in general medicine and transplantation are well documented. Few researchers have investigated the complex relationships between these constructs. This longitudinal study assessed coping style, self-regulatory ability, hostility, and social support at baseline among a cohort of 130 adult liver transplant recipients at the Starzl Transplant Institute, University of Pittsburgh Medical Center, and followed those subjects with interview and medical records data about personal and transplant-related stress, physical and mental health outcomes throughout the first post-transplant year. Results show a number of strong bidirectional relationships between coping style, self-regulatory ability, hostility, the caregiver relationship and family environment, personal and transplant-related stress over the second half of the first post-transplant year, and health (especially mental) outcomes at 12 months post-transplant. Stress mediates the relationship between psychosocial factors and mental health outcomes. The importance of those relationships to researchers and clinicians is discussed.

Individual and environmental correlates and predictors of early adherence and outcomes after liver transplantation

CONTEXT

Little is known about patients' contribution to health outcomes after liver transplantation. Yet, in other transplant recipients, nonadherent behavior is directly related to the leading causes of morbidity and mortality in liver transplant recipients.

OBJECTIVE

To examine patient and environmental factors in relation to all aspects of adherence to the posttransplantation regimen and health outcomes in the first 6 months after transplantation.

DESIGN

A descriptive analysis of individual and environmental factors in relation to adherence and health outcomes at 6 months after liver transplantation.

PARTICIPANTS, SETTING

One hundred fifty-two adult liver transplant recipients at the University of Pittsburgh Medical Center.

MAIN OUTCOME MEASURES

Adherence to medication taking, appointment keeping, lifestyle changes, mood, quality of life, and clinical markers of liver function.

RESULTS

Nonadherence was prevalent (47% with appointments, 73% with medication); relapse to drug/alcohol use occurred among a few recipients (5.6%), all with a history of substance abuse before transplantation. Patterns of coping, decision making, attitude, and social support were correlated with adherence, clinical markers, and psychological function (r = 0.22-0.45). Avoidant coping, affective dysregulation, and caregiver support emerged as robust predictors of negative clinical and mental health outcomes (beta = .224-.363).

CONCLUSION

This information about liver transplant recipients is important for researchers and clinicians. Researchers can develop guidelines by using stable but modifiable characteristics of patients to identify transplant candidates at risk of nonadherence. Such guidelines would enable clinicians to prepare patients better to manage the posttransplant regimen.
