Pre-Transplant Depression Is Associated with Length of Hospitalization, Discharge Disposition, and Survival after Liver Transplantation

Depressive symptom as a risk factor for cirrhosis in patients with primary biliary cholangitis: Analysis based on Lasso-logistic regression and decision tree models

BACKGROUND

Depressive symptoms are frequently observed in patients with primary biliary cholangitis (PBC). The role of depressive symptoms on cirrhosis has not been fully noticed in PBC. We aimed to establish a risk model for cirrhosis that took depressive symptoms into account.

METHODS

Depressive symptoms were assessed by the 17-item Hamilton Depression Rating Scale (HAMD-17). HAMD-17 score was analyzed in relation to clinical parameters. Least absolute shrinkage and selection operator (Lasso)-logistic regression and decision tree models were used to explore the effect of depressive symptoms on cirrhosis.

RESULTS

The rate of depressive symptom in patients with PBC (n = 162) was higher than in healthy controls (n = 180) (52.5% vs. 16.1%; p < .001). HAMD-17 score was negatively associated with C4 levels and positively associated with levels of alkaline phosphatase (ALP), γ-glutamyl transpeptidase (GGT), total bilirubin (TB), Immunoglobulin (Ig) G, and IgM (r = -0.162, 0.197, 0.355, 0.203, 0.182, 0.314, p < .05). In Lasso-logistic regression analysis, HAMD-17 score, human leukocyte antigen (HLA)-DRB1*03:01 allele, age, ALP levels, and IgM levels (odds ratio [OR] = 1.087, 7.353, 1.075, 1.009, 1.005; p < 0.05) were independent risk factors for cirrhosis. Elevated HAMD-17 score was also a discriminating factor for high risk of cirrhosis in patients with PBC in decision tree model.

CONCLUSIONS

Depressive symptoms were associated with disease severity. Elevated HAMD-17 score was a risk factor for cirrhosis in patients with PBC.

Disparities in Liver Transplantation Rates and Outcomes Among Adults with and without Mental Illnesses

BACKGROUND

Patients with mental illnesses face unique disparities in access to liver transplantation. We sought to compare rates of evaluation, transplantation, and post-transplant outcomes among patients with and without mental illnesses.

METHODS

Patients aged 18-75 with decompensated cirrhosis or hepatocellular carcinoma were identified from the Medicare Standard Analytic Files from 2014-2020. Regression analyses were used to examine the association between mental illness and evaluation by a transplant surgeon, receipt of transplant, and post-transplant outcomes.

RESULTS

Among 274,252 liver transplant candidates, 34,269 (12.5%) patients had depression and/or anxiety disorders and 8,184 (3.0%) had severe mental illnesses. The proportion of patients evaluated by a transplant surgeon was lower among patients with severe mental illnesses (14.1%), as well as individuals with depression and/or anxiety disorders (16.0%) versus the general population (18.5%) (p < 0.001). Similarly, utilization of transplantation rates was lower among patients with severe mental illness (1.1%) compared with depression and/or anxiety disorders (2.0%), as well as individuals without mental illnesses (3.8%) (p < 0.001). On multivariable regression analyses, mental illness remained independently associated with lower odds of evaluation and transplantation among patients with mental illnesses. In contrast, on adjusted analyses there were no differences in postoperative outcomes including perioperative complications, biliary complications, graft rejection, graft failure, and overall survival.

CONCLUSION

Despite lower rates of evaluation and transplant, patients with mental illnesses did not experience differences in most postoperative outcomes compared with patients without a mental illness.

Depression Is Associated With Non-Home Discharge After Coronary Artery Bypass Graft

INTRODUCTION

Depression is disproportionately high in patients with coronary artery disease and has been associated with adverse outcomes following coronary artery bypass graft (CABG). One quality metric, non-home discharge (NHD), can have substantial implications for patients and health care resource utilization. Depression increases the risk of NHD after many operations, but it has not been studied after CABG. We hypothesized that a history of depression would be associated with an increased risk of NHD following CABG.

METHODS

CABG cases were identified from the 2018 National Inpatient Sample using ICD-10 codes. Depression, demographic data, comorbidities, length of stay (LOS), rate of NHD were analyzed using appropriate statistical tests where a P-value < 0.05 was defined as statistically significant. Adjusted multivariable logistic regression models were used to assess independent association between depression and NHD as well as LOS while controlling for confounders.

RESULTS

There were 31,309 patients, of which 2743 (8.8%) had depression. Depressed patients were younger, females, in a lower income quartile, and more medically complex. They also demonstrated more frequent NHD and prolonged LOS. After adjusted multivariable analysis, depressed patients had a 70% increased odds of NHD (adjusted odds ratio: 1.70 [1.52-1.89] P < 0.001) and a 24% increased odds of prolonged LOS (AOR: 1.24 [1.12-1.38] P < 0.001).

CONCLUSIONS

From a national sample, depressed patients were associated with more frequent NHD following CABG. To our knowledge, this is the first study to demonstrate this, and it highlights the need for improved preoperative identification in order to improve risk stratification and timely allocation of discharge services.

Comorbid psychiatric disorders and long-term survival after liver transplantation in transplant facilities with a psychiatric consultation-liaison team: a multicenter retrospective study

OBJECTIVE

Comorbid psychiatric disorders negatively affect the survival rate of patients with some physical disorders. In liver transplant recipients, various psychiatric disorders have been identified as worsening prognosis. However, little is known about how the presence of any comorbid (overall) disorders affect the survival rate of transplant recipients. In this study, we examined the effect of overall comorbid psychiatric disorders on survival rate in liver transplant recipients.

METHODS

A total of 1006 recipients who underwent liver transplantation between September 1997 and July 2017 across eight transplant facilities with a psychiatric consultation-liaison team were identified consecutively. Recipients were categorized into those with comorbid psychiatric disorders and those without comorbid psychiatric disorders. In the comorbid psychiatric disorder group, psychiatric disorder diagnosis and time of diagnosis were investigated retrospectively.

RESULTS

Of the 1006 recipients, 294 (29.2%) had comorbid psychiatric disorders. Comorbid psychiatric disorders in the 1006 recipients were insomnia (N = 107, 10.6%), delirium (N = 103, 10.2%), major depressive disorder (N = 41, 4.1%), adjustment disorder (N = 19, 1.9%), anxiety disorder (N = 17, 1.7%), intellectual disability (N = 11, 1.1%), autism spectrum disorder (N = 7, 0.7%), somatic symptom disorder (N = 4, 0.4%) schizophrenia (N = 4, 0.4%), substance use disorder (N = 24, 2.4%) and personality disorder (N = 2, 0.2%). The most common time of psychiatric disorder diagnosis was within the first 3 months after liver transplantation (51.6%). The final mortality in patients with comorbid psychiatric disorder diagnosis during the five periods (pretransplant, transplant to 3 months, months to 1 year, 1 to 3 years, and over 3 years posttransplant) was 16.2%, 18.8%, 39.1%, 28.6%, and 16.2% respectively, and there were no significant differences between the five periods (χ2 = 8.05, df = 4, p = 0.09). Overall comorbid psychiatric disorders were significantly associated with shorter survival time (log-rank test: p = 0.01, hazard ratio: 1.59 [95% confidence interval: 1.14-2.21], survival rate at the endpoint [%]: 62.0 vs. 83.3). However, after adjusting for confounding variables using Cox proportional hazards regression, there was no significant effect of overall comorbid psychiatric disorders on prognosis.

CONCLUSION

Comorbid psychiatric disorders did not affect the survival rate of liver transplant recipients in this study.

Impact of psychosocial factors on medication level variability index and outcomes in pediatric liver transplant recipients

BACKGROUND

Caregivers play an important role in maintaining a functioning graft after pediatric liver transplantation. Therefore, the psychosocial factors of both patients and caregivers can have a critical impact on transplant outcomes. Appropriate assessment and recognition of these factors pre-transplantation may allow transplant teams to better define the needs of pediatric organ recipients and develop specific countermeasures, which may then contribute toward improving transplant outcomes.

METHODS

We studied 136 pediatric LT recipients followed at Texas Children's Hospital. Licensed social workers conducted comprehensive pre-transplant assessments on each patient, consisting of 22 psychosocial variables that were thought to impact adherence, which were reviewed during our study period. Non-adherence was determined using the MLVI for up to 4 years after transplantation. Biopsy-confirmed rejection episodes were assessed in the first 3 years after liver transplantation.

RESULTS

Factors significantly associated with non-adherence (defined as MLVI >2) included parental age and parental education level at assessment, type of insurance, and household income. The number of ACR episodes trended higher in patients with non-adherence, and these patients had a higher number of moderate to severe rejection episodes but this trend was not statistically significant.

CONCLUSIONS

Psychosocial characteristics such as parental age, education level, insurance, and household income may contribute significantly to suboptimal adherence to medications after transplantation. Identification of these psychosocial factors and early intervention is essential to the success and equitable care of our pediatric LT recipients.

Gut-derived systemic inflammation as a driver of depression in chronic liver disease

Depression and chronic liver disease (CLD) are important causes of disability, morbidity and mortality worldwide and their prevalence continues to rise. The rate of depression in CLD is high compared to that of the general population and is comparable to the increased rates observed in other medical comorbidities and chronic inflammatory conditions. Notably, a comorbid diagnosis of depression has a detrimental effect on outcomes in cirrhosis. Systemic inflammation is pivotal in cirrhosis-associated immune dysfunction - a phenomenon present in advanced CLD (cirrhosis) and implicated in the development of complications, organ failure, disease progression, increased infection rates and poor outcome. The presence of systemic inflammation is also well-documented in a cohort of patients with depression; peripheral cytokine signals can result in neuroinflammation, behavioural change and depressive symptoms via neural mechanisms, cerebral endothelial cell and circumventricular organ signalling, and peripheral immune cell-to-brain signalling. Gut dysbiosis has been observed in both patients with cirrhosis and depression. It leads to intestinal barrier dysfunction resulting in increased bacterial translocation, in turn activating circulating immune cells, leading to cytokine production and systemic inflammation. A perturbed gut-liver-brain axis may therefore explain the high rates of depression in patients with cirrhosis. The underlying mechanisms explaining the critical relationship between depression and cirrhosis remain to be fully elucidated. Several other psychosocial and biological factors are likely to be involved, and therefore the cause is probably multifactorial. However, the role of the dysfunctional gut-liver-brain axis as a driver of gut-derived systemic inflammation requires further exploration and consideration as a target for the treatment of depression in patients with cirrhosis.

Hepatic encephalopathy and depression in chronic liver disease: is the common link systemic inflammation?

Hepatic encephalopathy and depression share a number of clinical features, such as cognitive impairment and psychomotor retardation, and are highly prevalent in patients with chronic liver disease. Both conditions signify a poor prognosis, carry an increased mortality and are major determinants of reduced health related quality of life. The pathophysiology of hepatic encephalopathy is complex. Whilst cerebral accumulation of ammonia is well-recognised as being central to the development of hepatic encephalopathy, systemic inflammation, which acts in synergy with hyperammonaemia, is emerging as a key driver in its development. The pro-inflammatory state is also widely documented in depression, and peripheral to brain communication occurs resulting in central inflammation, behavioural changes and depressive symptoms. Gut dysbiosis, with a similar reduction in beneficial bacteria, increase in pathogens and decreased bacterial diversity, has been observed in both hepatic encephalopathy and depression, and it may be that the resultant increased bacterial translocation causes their shared inflammatory pathophysiology. Whilst the literature on a positive association between hepatic encephalopathy and depression in cirrhosis remains to be substantiated, there is evolving evidence that treatment with psychobiotics may be of dual benefit, improving cognition and mood in cirrhosis.

Depression Predicts Non-Home Discharge After Abdominal Aortic Aneurysm Repair

BACKGROUND

Mental health's impact on vascular surgical patients has long been overlooked. While outside the expertise of most surgeons, understanding the role that depression plays in the postoperative course could provide additional insight into opportunities to improve surgical outcomes and healthcare value. Additionally, non-home discharge (NHD) to a rehabilitation or skilled nursing facility after surgery is associated with impaired quality of life and higher postdischarge complications, readmissions, and mortality. We hypothesized that depression would be associated with an increased risk for NHD following abdominal aortic aneurysm (AAA) repair.

METHODS

Nonruptured AAA repair cases were identified from the National Inpatient Sample (NIS) using ICD-9 codes between 2005 and 2014. Depression, comorbidities, postoperative complications, and discharge destination were evaluated using statistical tests as appropriate to the data. A hierarchical multivariable logistic regression controlling for hospital level variation was used to examine the independent association between depression, and the primary outcome of NHD controlling for median income and confounders meeting P < 0.05 on univariate analysis.

RESULTS

There were 99,934 total cases analyzed, of which 4,755 (4.8%) were diagnosed with depression and 10,618 (11.9%) required NHD. Patients with depression were younger, more likely to be women, white, have diabetes, chronic obstructive pulmonary disease, hypertension, tobacco use, and more likely to experience a postoperative complication. On adjusted multivariable analysis, patients with depression were more likely to require NHD (odds ratio [OR] 1.87, 95% confidence interval [CI]: 1.68-2.08, c-statistic = 0.82). On stratified analysis by operative approach, depression had a larger effect estimate in endovascular repair (OR 2.19; 95% CI: 1.90-2.52) versus open repair (OR 1.60; 95% CI: 1.38-1.87).

CONCLUSIONS

In a nationally representative sample, patients with depression were more likely to require NHD after AAA repair. This study highlights the importance that depression plays in postoperative outcomes after AAA repair. Furthermore, addressing mental health preoperatively has the potential to improve outcomes in patients undergoing AAA repair.

COVID-19 Pandemic Stress-Induced Somatization in Transplant Waiting List Patients

Background: The coronavirus disease 2019 (COVID-19) pandemic has resulted in widespread socioeconomic restrictions including quarantine, social distancing and self-isolation. This is the first study investigating the psychological impact of the pandemic on patients waiting for liver or kidney transplantation, a particularly vulnerable group. Methods: Twenty-seven patients on the transplantation waiting list and 43 healthy controls took part in an online survey including the Beck Depression Inventory (BDI-2), the Brief Symptom Inventory-18 (BSI-18), the Pittsburgh Sleep Quality Index (PSQI), the Alcohol Use Identification Test (AUDIT-C), the 12-item Operationalized Psychodynamic Diagnosis Structure Questionnaire (OPD-SQS) and a questionnaire to determine cognitions and beliefs, attitude and fear related to COVID-19. Results: BSI-18 Somatization was increased in waiting list patients compared to controls. Correlation analyses indicated a relationship between Somatization and the fear of contracting the coronavirus in the patient group; however this association was weak. In patients and controls, other psychologicial symptoms (depression, anxiety) correlated highly with emotional distress due to social distancing. There were no differences between patients and controls in depression scores and sleep disturbances. Alcohol consumption and personality structure were not related to COVID-19 fears. Conclusion: In times of the first lockdown during the COVID-19 pandemic, patients on the transplantation waiting list have high somatization symptoms associated with COVID-19 fears. As vulnerable group, they need psychological counseling to improve mental well-being during times of crisis.

Patients with depression are less likely to go home after critical limb revascularization

BACKGROUND

Although often overlooked during the preoperative evaluation, recent evidence has suggested that depression in patients with peripheral artery disease is associated with increased postoperative complications, including decreased primary and secondary patency after revascularization and an increased risk of major amputation and mortality. Postoperative nonhome discharge (NHD) is an important outcome for patients and has also been associated with other adverse outcomes; however, the effect that depression has on NHD after vascular surgery has remained unexplored. We hypothesized that depression would be associated with an increased risk of NHD after revascularization for chronic limb threatening ischemia (CLTI).

METHODS

Endovascular, open, and hybrid (combined open and endovascular) cases of revascularization for CLTI were identified from the 2012 to 2014 National (Nationwide) Inpatient Sample. CLTI, diagnoses of depression, and medical comorbidities were defined using the corresponding International Classification of Diseases, Ninth Revision, Clinical Modification codes. A hierarchical multivariable binary logistic regression controlling for hospital level variation and for confounders meeting P <.01 on bivariate analysis was used to examine the association between depression and NHD. A sensitivity analysis after coarsened exact matching for baseline characteristics that differed between the two groups was performed to reduce any imbalance.

RESULTS

A total of 64,817 cases were identified, of which 5472 (8.4%) included a diagnosis of depression and 16,524 (25.5%) NHD. The patients with depression were younger and more likely to be women and white, have multiple comorbidities and a nonelective admission, and experience a postoperative complication (P <.05). On unadjusted analyses, patients with depression had an 8% absolute increased risk of requiring NHD (32.1% vs 24.9%; P <.001). On multivariable analysis, patients with depression had an increased odds for NHD (odds ratio [OR], 1.50; 95% confidence interval [CI], 1.40-1.61; c-statistic, 0.81) compared with those without depression. After stratification by operative approach, depression had a larger effect estimate in endovascular revascularization (OR, 1.57; 95% CI, 1.42-1.74) compared with open (OR, 1.45; 95% CI, 1.30-1.62). A test for interaction between depression and gender identified that men with depression had greater odds of NHD compared with women with depression (OR, 1.68; 95% CI, 1.51-1.88; vs OR, 1.37; 95% CI, 1.25-1.51; interaction P <.01). A sensitivity analysis after coarsened exact matching confirmed these findings.

CONCLUSIONS

To the best of our knowledge, the present study is the first to identify an association between depression and NHD after revascularization for CLTI. These results provide further evidence of the negative effects that comorbid depression has on patients undergoing revascularization for CLTI. Future studies should examine whether treating depression can improve the outcomes in this patient population.

The impact of psychiatric disorders on outcomes following heart transplantation in children

Psychiatric disorders are common in pediatric HTx recipients. However, the impact of psychiatric comorbidities on patient outcomes is unknown. We aimed to assess the impact of disorders of adjustment, depression, and anxiety on HTx outcomes in children; hypothesizing that the presence of psychiatric disorders during or preceding HTx would negatively impact outcomes. All pediatric HTx recipients ≥8 years of age who survived to hospital discharge were identified from a novel linkage between the PHIS and SRTR databases (2002-2016). Psychiatric disorders were identified using ICD codes during or preceding the HTx admission. Post-transplant graft survival, freedom from readmission, and freedom from rejection were analyzed using the Kaplan-Meier method. Multivariable Cox proportional hazard models were used to adjust for covariates. A total of 1192 patients were included, of which 133 (11.2%) had depression, 197 (16.5%) had anxiety, and 218 (18.3%) had adjustment disorders. The presence of depression was independently associated with higher rates of readmission (60.9% vs 54.1% at 6 months) (AHR 1.63, 95% CI 1.22-2.18, P = .001) and inferior graft survival (70.2% vs 83.4% at 5 years) (AHR 1.62, 95% CI 1.14-2.3, P = .007). Anxiety was independently associated with higher rates of readmission (60.4% vs 53.9% at 6 months) (AHR 1.46, 95% CI 1.09-1.94, P = .01). Anxiety and depression in the pretransplant period are independently associated with outcomes following HTx in children. Evaluation and management of psychiatric comorbidities represents an important component of care in this vulnerable population.

Characterizing patient-reported outcomes in veterans with cirrhosis

Background and aims

The Veterans Health Administration (VA) cares for over 80,000 Veterans with cirrhosis annually. Given the importance of understanding patient reported outcomes in this complex population, we aimed to assess the associations between attitudes towards care, disease knowledge, and health related quality of life (HRQoL) in a national sample.

Methods

In this cross-sectional study, we mailed paper surveys to a random sample of Veterans with cirrhosis, oversampling those with decompensated disease. Surveys included the Veterans RAND 12-Item Health Survey (measuring HRQoL) and questions about demographics, characteristics of care, satisfaction with care (“attitudes towards care”), and symptoms of cirrhosis. Those who reported being “unsure” about whether they had decompensation events were defined as “unsure about cirrhosis symptoms” (“disease knowledge”). We used multivariable regression models to assess the factors associated with HRQoL.

Results

Of 1374 surveys, 551 (40%) completed surveys were included for analysis. Most Veterans (63%) were “satisfied” or “very satisfied” with VA liver care. Patients often self-reported being unsure about whether they had experienced hepatic decompensation events (34%). Overall average physical (PCS) and mental (MCS) component scores of HRQoL were 30±11 and 41±12. In multivariable regression models, hepatic decompensation (PCS:β = -3.8, MCS:β = -2.2), medical comorbidities (β = −-2.0, β = -1.7), and being unsure about cirrhosis symptoms (β = -1.9, β = -3.3) were associated with worse HRQoL, while age (β = 0.1, β = 0.2) and satisfaction with care (β = 0.6; β = 1.6) were associated with significantly better HRQoL.

Conclusions

Hepatic decompensation, lower satisfaction with care, and being unsure about cirrhosis symptoms were associated with reduced QOL scores in this national cohort.

The Educational Value of Outpatient Consultation-Liaison Rotations: A White Paper From the Academy of Consultation-Liaison Psychiatry Residency Education Subcommittee

Background

As mental health services in outpatient medical clinics expand, psychiatrists must be trained to practice in these settings.

Objectives

The Academy of Consultation-Liaison Psychiatry residency education subcommittee convened a writing group with the goal of summarizing the current evidence about outpatient consultation-liaison psychiatry (CLP) training and providing a framework for CLP educators who are interested in developing outpatient CLP rotations within their programs.

Method

MEDLINE (via PubMed), Embase, and PsycINFO (via OVID) were reviewed each from inception to December 2019, for psychiatric CLP services in ambulatory settings that involved residents or fellows. The CLP education guidelines were reviewed for recommendations relevant to outpatient CLP. We also searched MedEd portal for published curriculums relevant to CLP. The group held 2 conferences to reach consensus about recommendations in setting up outpatient CLP rotations.

Results

Seventeen articles, 3 Academy of Consultation-Liaison Psychiatry–supported guidelines, and 8 online didactic resources were identified as directly reporting on the organization and/or impact of an outpatient CLP rotation. These manuscripts indicated that residents found outpatient CLP rotations effective and relevant to their future careers. However, the literature provided few recommendations for establishing formal outpatient CLP training experiences.

Conclusions

Outpatient CLP rotations offer multiple benefits for trainees, including exposure to specific clinical scenarios and therapeutic interventions applicable only in the outpatient setting, increased continuity of care, and the unique experience of providing liaison and education to non-mental health providers. The article outlines recommendations and examples for developing outpatient CLP rotations which CLP educators can incorporate in their programs.

Women who undergo liver transplant have longer length of stay post-transplant compared with men

BACKGROUND

Women on the liver transplant waitlist are at greater risk of hospitalization compared with men, but whether this impacts length of stay (LOS) post-transplant is unknown. We aimed to evaluate gender disparities in post-transplant LOS, an important surrogate of health resource utilization post-transplant.

METHODS

Using the UNOS/OPTN registry, we analysed all non-Status 1 adult deceased donor liver transplant recipients without exception points from 2008 to 2017. Poisson regression associated female gender with post-transplant LOS.

RESULTS

Of 27 294 transplant recipients, 36% were women. Women were more likely to be hospitalized pretransplant than men (44% vs 39%, P < .01). Post-transplant, women were more likely to have prolonged (≥20d) LOS (25% vs 22%, P < .01). In univariable analysis, female gender was associated with longer post-transplant LOS (IRR 1.09, 95%CI 1.06-1.12, P < .01). Prolonged pretransplant admission was also associated with post-transplant LOS (IRR 1.83, 95%CI 1.77-1.89, P < .01). In multivariable analysis, female gender remained independently associated with post-transplant LOS (aIRR 1.05, 95%CI 1.02-1.08, P < .01), after adjustment for age, UNOS region, insurance type, MELDNa, cirrhosis complications, and donor risk index. Pretransplant hospitalization mediated this relationship, explaining 14.1% (95%CI 9.7%-25.4%) of the total effect.

CONCLUSIONS

Women who undergo deceased donor liver transplant have increased healthcare utilization in the peritransplant period compared with men. Reducing gender disparities in liver transplantation, including the disproportionate burden of healthcare utilization by women pre- and post-transplant, will require interventions targeted at preventing hospitalization among women on the transplant waitlist and developing tools aimed at better characterizing the severity of end-stage liver disease in women.

An exploratory study of the experiences of deceased-donor liver transplant recipients and their need for psychotherapeutic support

AIMS AND OBJECTIVES

This study aimed to explore the experiences of liver transplant recipients during their journey through the treatment and their need for psychotherapeutic support related to this process.

BACKGROUND

Over time, measures of survival and quality of life in liver transplant recipients have continued to improve but their emotional needs remain under explored. In the longer-term recovery from transplantation, the focus shifts from physical health to psychological health. In the UK, there are no known embedded adult psychological services in liver transplant centres to react to this need.

DESIGN

A qualitative descriptive design was used.

METHODS

Grounded theory analysis was used to study the narratives of six adult liver transplant recipients. Through a process of coding, conceptual categories were established to describe the participant experiences. The study adhered to the EQUATOR checklist, SRQR.

RESULTS

Four categories emerged that were related to the experience of liver transplantation for the recipients. These were a process of adjustment, the phenomenon of waiting, liver transplant as a transformative experience and on the value of support. The participants identified a lack of psychotherapeutic support provided by the liver transplant service and felt that an embedded psychotherapeutic service would promote accessing such support during challenging times.

CONCLUSION

Through the process of liver transplantation, recipients experience challenges with adjustment, waiting, feeling transformed and they value support with these feelings. In correlation with other studies, the findings of this study highlight the need for providing psychotherapeutic support within liver transplant services.

RELEVANCE TO CLINICAL PRACTICE

The study provides evidence to support recommendations for a conjoined psychotherapy service within liver transplant services to support patients with their holistic needs.

Impact of psychosocial comorbidities on clinical outcomes after liver transplantation: Stratification of a high-risk population

BACKGROUND

Liver transplantation is the accepted standard of care for end-stage liver disease due to a variety of etiologies including decompensated cirrhosis, fulminant hepatic failure, and primary hepatic malignancy. There are currently over 13000 candidates on the liver transplant waiting list emphasizing the importance of rigorous patient selection. There are few studies regarding the impact of additional psychosocial barriers to liver transplant including financial hardship, lack of caregiver support, polysubstance abuse, and issues with medical non-compliance. We hypothesized that patients with certain psychosocial comorbidities experienced worse outcomes after liver transplantation.

AIM

To assess the impact of certain pre-transplant psychosocial comorbidities on outcomes after liver transplantation.

METHODS

A retrospective analysis was performed on all adult patients from 2012-2016. Psychosocial comorbidities including documented medical non-compliance, polysubstance abuse, financial issues, and lack of caregiver support were collected. The primary outcome assessed post-transplantation was survival. Secondary outcomes measured included graft failure, episodes of acute rejection, psychiatric decompensation, number of readmissions, presence of infection, recidivism for alcohol and other substances, and documented caregiver support failure.

RESULTS

For the primary outcome, there were no differences in survival. Patients with a history of psychiatric disease had a higher incidence of psychiatric decompensation after liver transplantation (19% vs 10%, P = 0.013). Treatment of psychiatric disorders resulted in a reduction of the incidence of psychiatric decompensation (21% vs 11%, P = 0.022). Patients with a history of polysubstance abuse in the transplant evaluation had a higher incidence of substance abuse after transplantation (5.8% vs 1.2%, P = 0.05). In this cohort, 15 patients (3.8%) were found to have medical compliance issues in the transplant evaluation. Of these specific patients, 13.3% were found to have substance abuse after transplantation as opposed to 1.3% in patients without documented compliance issues (P = 0.03).

CONCLUSION

Patients with certain psychosocial comorbidities had worse outcomes following liver transplantation. Further prospective and multi-center studies are warranted to properly determine guidelines for liver transplantation regarding this high-risk population.

A Behavioral Health Program for Alcohol Use Disorder, Substance Abuse, and Depression in Chronic Liver Disease

Alcohol use disorder, substance abuse, and depression are illnesses that deteriorate the quality of life (QOL) of patients with chronic liver disease (CLD). Screening and behavioral health programs integrated into routine practice can mitigate the deleterious effects of such illnesses but have not been adopted in hepatology practices. We implemented a behavioral health program based on the Screening, Brief Intervention, and Referral to Treatment (SBIRT) model and assessed its acceptability and effectiveness in improving QOL. This was a quality improvement study. Patients with CLD and a scheduled outpatient visit in the hepatology clinic were screened while waiting for their appointment. All patients who screened positive for any of the three illnesses were offered a brief intervention (BI) at the point of care and at 3 months by a trained social worker. The BI used the principles of motivational interviewing and cognitive behavioral therapy. Severity of illness was assessed at baseline, 3 months, and 6 months. Participants completed an acceptability survey at 6 months. We screened 303 patients; 61.7% were positive for any of the three illnesses assessed. Among the positive patients, depression was most common (48.4%), alcohol and substance abuse were each 26%. For the 95 patients who underwent BI, QOL improved from baseline to 3 and 6 months (P < 0.001) and patients with depression improved the most. Depression was the only independent predictor of change in QOL over time. Of the enrolled patients, 82% agreed BIs improved their overall care and 87% indicated a desire to continue with the behavioral program. Conclusion: An outpatient behavioral health program based on the SBIRT model is acceptable to patients with CLD and may help improve QOL over time.

Psychopharmacology in transplantation medicine

Organ transplantation has become a well-established treatment option in patients with end-stage organ diseases. Although quality of life has markedly improved, psychiatric disorders before and after transplantation are more frequent compared to the general population. Psychopharmacological treatment is recommended for almost all mental disorders according to current guidelines, but may pose particular problems in organ transplant patients. Changes in the metabolism and elimination of drugs during organ insufficiency, drug interactions, and overlapping side effects between psychopharmacological and immunosuppressive drugs are challenging problems in clinical management. Furthermore, questions frequently arise concerning the use of psychopharmacological treatment options for sleeping and anxiety disorders. This article reviews psychopharmacology in organ transplant patients, with particular attention to frequent psychiatric disorders observed in the disease course of end-stage organ diseases.

Depression in cirrhosis - a prospective evaluation of the prevalence, predictors and development of a screening nomogram

BACKGROUND

Depression is associated with substantial morbidity and mortality in cirrhosis, but is underdiagnosed and undertreated.

AIMS

Using the Mini International Neuropsychiatric Interview (MINI) as a gold-standard, to determine prevalence, predictors, and outcomes of depression, and to develop a screening nomogram for use in cirrhosis patients.

METHODS

Cirrhotic outpatients 18-80 years of age, not on anti-depressants, were consecutively recruited from liver clinics at three tertiary care hospitals. Baseline health-related quality of life (HRQoL) and frailty were determined by the chronic liver disease questionnaire, EQ-VAS, Clinical Frailty Scale and Fried Frailty Criteria. Depression was identified using the MINI and participants were followed up to 6 months to determine unplanned hospitalization/death.

RESULTS

Of 305 patients, 62% were male; mean age 55(10) years; mean MELD 12.5(5), 61% Child Pugh B/C. Prevalence of depression 18% by MINI. Patients with depression had lower baseline HRQoL and higher frailty scores. Five independently predictive factors were used to develop a clinical nomogram for the diagnosis of clinical depression. These included three Hospital Anxiety and Depression Screening tool variables: "I have lost interest in my appearance" (adjusted odds ratio [aOR] 2.2, P = 0.006), "I look forward with enjoyment to things" (aOR 2.0, P = 0.02), "I feel cheerful" (aOR 2.8, P = 0.002), and two demographic variables: younger age (aOR 0.92, P = 0.001) and not being married or in a common-law relationship (aOR 0.30, P = 0.008).

CONCLUSIONS

Depression is common in patients with cirrhosis. It has a significant impact on HRQoL and functional status. The developed clinical nomogram is promising for the rapid screening of depression in patients with cirrhosis.

Depressive symptoms, frailty, and adverse outcomes among kidney transplant recipients

Depressive symptoms and frailty are each independently associated with morbidity and mortality in kidney transplant (KT) recipients. We hypothesized that having both depressive symptoms and frailty would be synergistic and worse than the independent effect of each. In a multicenter cohort study of 773 KT recipients, we measured the Fried frailty phenotype and the modified 18-question Center for Epidemiologic Studies-Depression Scale (CES-D). Using adjusted Poisson regression and survival analysis, we tested whether depressive symptoms (CES-D score > 14) and frailty were associated with KT length of stay (LOS), death-censored graft failure (DCGF), and mortality. At KT admission, 10.0% of patients exhibited depressive symptoms, 16.3% were frail, and 3.6% had both. Recipients with depressive symptoms were more likely to be frail (aOR = 3.97, 95% CI: 2.28-6.91, P < 0.001). Recipients with both depressive symptoms and frailty had a 1.88 times (95% CI: 1.70-2.08, P < 0.001) longer LOS, 6.20-fold (95% CI:1.67-22.95, P < 0.01) increased risk of DCGF, and 2.62-fold (95% CI:1.03-6.70, P = 0.04) increased risk of mortality, compared to those who were nonfrail and without depressive symptoms. There was only evidence of synergistic effect of frailty and depressive symptoms on length of stay (P for interaction < 0.001). Interventions aimed at reducing pre-KT depressive symptoms and frailty should be explored for their impact on post-KT outcomes.

The feasibility of a group stress management Liver SMART intervention for patients with end-stage liver disease: A pilot study

OBJECTIVE

Structured, empirically supported psychological interventions are lacking for patients who require organ transplantation. This stage IA psychotherapy development project developed and tested the feasibility, acceptability, tolerability, and preliminary efficacy of an 8-week group cognitive behavioral stress management intervention adapted for patients with end-stage liver disease awaiting liver transplantation.

METHOD

Twenty-nine English-speaking United Network for Organ Sharing-registered patients with end-stage liver disease from a single transplantation center enrolled in 8-week, group cognitive-behavioral liver stress management and relaxation training intervention adapted for patients with end-stage liver disease. Patients completed pre- and postintervention surveys that included the Beck Depression Inventory II and the Beck Anxiety Inventory. Feasibility, acceptability, tolerability, and preliminary efficacy were assessed.ResultAttendance rate was 69.40%. The intervention was rated as "good" to "excellent" by 100% of participants who completed the postintervention survey in teaching them new skills to relax and to cope with stress, and by 94.12% of participants in helping them feel supported while waiting for a liver transplant. No adverse events were recorded over the course of treatment. Attrition was 13.79%. Anxious and depressive symptoms were not statistically different after the intervention.Significance of resultsThe liver stress management and relaxation training intervention is feasible, acceptable, and tolerable to end-stage liver disease patients within a transplant clinic setting. Anxious and depressive symptoms remained stable postintervention. Randomized controlled trials are needed to study the intervention's effectiveness in this population.

Depression, social support, and clinical outcomes following lung transplantation: a single-center cohort study

Depressive symptoms are common among lung transplant candidates and have been associated with poorer clinical outcomes in some studies. Previous studies have been plagued by methodologic problems, including small sample sizes, few clinical events, and uncontrolled confounders, particularly perioperative complications. In addition, few studies have examined social support as a potential protective factor. We therefore examined the association between pretransplant depressive symptoms, social support, and mortality in a large sample of lung transplant recipients. As a secondary aim, we also examined the associations between psychosocial factors, perioperative outcomes [indexed by hospital length of stay (LOS)], and mortality. We hypothesized that depression would be associated with longer LOS and that the association between depression, social support, and mortality would be moderated by LOS. Participants included lung transplant recipients, transplanted at Duke University Medical Center from January 2009 to December 2014. Depressive symptoms were evaluated using the Beck Depression Inventory (BDI-II) and social support using the Perceived Social Support Scale (PSSS). Medical risk factors included forced vital capacity (FVC), partial pressure of carbon dioxide (PCO₂ ), donor age, acute rejection, and transplant type. Functional status was assessed using six-minute walk distance (6MWD). We also controlled for demographic factors, including age, gender, and native disease. Transplant hospitalization LOS was examined as a marker of perioperative clinical outcomes. Participants included 273 lung recipients (174 restrictive, 67 obstructive, 26 cystic fibrosis, and six "other"). Pretransplant depressive symptoms were common, with 56 participants (21%) exhibiting clinically elevated levels (BDI-II ≥ 14). Greater depressive symptoms were associated with longer LOS [adjusted b = 0.20 (2 days per 7-point higher BDI-II score), P < 0.01]. LOS moderated the associations between depressive symptoms (P = 0.019), social support (P < 0.001), and mortality, such that greater depressive symptoms and lower social support were associated with greater mortality only among individuals with longer LOS. For individuals with LOS ≥ 1 month, clinically elevated depressive symptoms (BDI-II ≥ 14) were associated with a threefold increased risk of mortality (HR = 2.97). Greater pretransplant depressive symptoms and lower social support may be associated with greater mortality among a subset of individuals with worse perioperative outcomes.
