Discrepancies Between Beliefs and Behavior

Characterization of CKD illness representation profiles using patient-level factors

BACKGROUND

Illness perceptions are the unique perspective individuals have on their illness, based on their context and experiences, and are associated with patient outcomes including coping and adherence. The purpose of this study was to explore characteristics that may be driving membership in illness perceptions cluster groups for adults with chronic kidney disease (CKD).

METHODS

This study was conducted within the multicenter longitudinal Chronic Renal Insufficiency Cohort (CRIC) Study. Cross-sectional data were collected and combined with CRIC data. Illness perceptions were measured using the Revised Illness Perception Questionnaire. Clustering analysis was conducted in R, and bivariate analysis including linear regression was performed in STATA 16.

RESULTS

The sample (n = 197) had a mean age of 68, was 52% women, 53% non-White, and mean estimated glomerular filtration rate (eGFR) 56 ml/min/1.73 m2. Three cluster groups were identified, labeled as "Disengaged" (n = 20), "Well-Resourced" (n = 108), and "Distressed" (n = 69). The "Disengaged" group was characterized by low CKD knowledge, many recent hospitalization days, and the lowest perceived CKD burden. The "Well-Resourced" group was characterized by the highest levels of education, CKD knowledge, optimism, and medication adherence. The "Distressed" group was characterized by the highest levels of depression scores, comorbidity burden, CKD burden, CKD symptoms, and lowest optimism. Group membership significantly predicted the number of hospitalization days in adjusted analyses.

CONCLUSIONS

Illness perceptions groups are associated with number of hospitalization days but are independent of many patient characteristics. Illness perceptions data could be used to tailor care for specific patients at risk for poor health outcomes.

Extended-release tacrolimus dosing and outcomes in pediatric and young adult transplant recipients - A single-center experience

BACKGROUND

Published data on LCP-tacrolimus (LCPT) in the pediatric population are limited.

METHODS

This single-center, retrospective, observational study describes LCPT doses needed to reach therapeutic ranges in pediatric and young adult kidney and liver transplant recipients in both de novo usage and conversion from immediate-release tacrolimus (IR-Tac). Adverse outcomes up to 12 months after LCPT initiation were also evaluated.

RESULTS

Forty-one transplant recipients (30 kidney, 11 liver) were included. The median initial doses of LCPT were 0.034 mg/kg (IQR 0.019) de novo and 0.09 mg/kg (IQR = 0.076) converted. The median doses at first therapeutic level were 0.086 mg/kg (IQR 0.028) de novo and 0.1 mg/kg (IQR 0.066) converted. The median LCPT:IR-Tac conversion ratio initially was 0.7 and 0.75 at therapeutic levels. The rate of AKI per 100 days of exposure to IR-Tac was 0.546 and 0.439 on LCPT. The percentage of patients with rejection was not different before and after conversion (clinical rejection 8.6% [n = 3] vs 11.4% [n = 4], p = .6; biopsy-proven rejection 2.9% [n = 1] vs 11.4% [n = 4], p = .11). One patient had graft loss unrelated to rejection, and the graft was explanted.

CONCLUSION

In this study, pediatric and young adult abdominal transplant recipients had therapeutic tacrolimus levels at LCPT doses below the adult-labeled dose; the conversion ratio from IR-Tac to LCPT at therapeutic level was similar. There were no identified safety concerns in de novo or converted LCPT use in pediatric and young adult patients.

Reciprocal associations between beliefs about medicines, health locus of control and adherence to immunosuppressive medication in allogeneic hematopoietic cell transplant patients: Findings from the ADE-TRAM study

PURPOSE

Patients undergoing allogenic hematopoietic stem cell transplantation (allo-HSCT) are required to strictly adhere to immunosuppressive medications to avoid rejection and infective complications. Since medication adherence is among the most important modifiable behaviors to achieve better outcomes, the aims of this study were to measure the baseline and longitudinal trends of medication adherence and investigate the psychological factors associated with medication adherence in allo-HSCT patients.

METHODS

This was a single-center, longitudinal study of patients who underwent allo-HSCT to treat hematological malignancies at the University hospital of Florence (Italy). Adherence was measured with the Immunosuppressive Medication Self-Management Scale; psychological factors (i.e., beliefs about medicines and health locus of control) were measured with the Beliefs About Medicines Questionnaire and Multidimensional Health locus of Control Scale. Data were collected 1, 3, 6 and 12 months after discharge. A mixed effects model was performed after adjusting for demographic characteristics.

RESULTS

50 adult patients were included in this study. Adherence to immunosuppressant was optimal and increased significantly 3 months after bone marrow transplantation (B = 0.23, p = 0.041). Patients with lower concerns about immunosuppressive medications were more likely to be adherent (B = 0.02, p = 0.040), while those having beliefs that their disease was due to external factors were less likely to be adherent (B = -0.02, p = 0.026) than their counterparts.

CONCLUSIONS

These results underline the importance of psychological factors in affecting adherence to immunosuppressants of allo-HSCT patients. Healthcare providers and researchers should target medication beliefs and reorient locus of control with appropriate interventions, in order to improve adherence.

Improving adherence to immunosuppression after liver or kidney transplantation in individuals with impairments in personality functioning – A randomized controlled single center feasibility study

Introduction

Although adherence to immunosuppressive medication is the key factor for long-term graft survival today, 20–70% of transplant recipients are non-adherent to their immunosuppressive medication.

Objective

A prospective, randomized, controlled single-center feasibility study was designed to evaluate the impact of a step guided multicomponent interprofessional intervention program for patients after kidney or liver transplantation on adherence to their immunosuppressive medication in daily clinical practice.

Materials and methods

The intervention consisted of group therapy and daily training as well as individual sessions in a step guided approach. The primary endpoint of the study was adherence to immunosuppression as assessed with the “Basel Assessment of Adherence to Immunosuppressive Medications Scale” (BAASIS). The coefficient of variation (CV%) of Tacrolimus (TAC) through levels and the level of personality functioning was a secondary endpoint. We conducted six monthly follow-up visits.

Results

Forty-one age- and sex-matched patients [19 females, 58.5 (SD = 10.56) years old, 22 kidney- and 19 liver transplantation] were randomized to the intervention- (N = 21) or control-group (N = 20). No differences between intervention- and control groups were found in the primary endpoint adherence and CV% of TAC. However, in further exploratory analyses, we observed that individuals with higher impairments in personality functioning showed higher CV% of TAC in the controls. The intervention might compensate personality-related susceptibility to poor adherence as evident in CV% of TAC.

Discussion

The results of the feasibility study showed that this intervention program was highly accepted in the clinical setting. The Intervention group could compensate higher CV% of TAC after liver or kidney transplantation in individuals with lower levels of personality functioning and non-adherence.

Reliability and Validity of the Japanese Version of the Basel Assessment of Adherence to Immunosuppressive Medications Scale in Kidney Transplant Recipients

A valid and reliable instrument that can measure adherence is needed to identify nonadherent patients and to improve adherence. However, there is no validated Japanese self-report instrument to evaluate adherence to immunosuppressive medications for transplant patients. The purpose of this study was to determine the reliability and validity of the Japanese version of the Basel Assessment of Adherence to Immunosuppressive Medications Scale (BAASIS).

Methods

We translated the BAASIS into Japanese and developed the Japanese version of the BAASIS (J-BAASIS) according to the International Society of Pharmacoeconomics and Outcomes Research task force guidelines. We analyzed the reliability (test-retest reliability and measurement error) and validity of the J-BAASIS (concurrent validity with the medication event monitoring system and the 12-item Medication Adherence Scale) referring to the COSMIN Risk of Bias checklist.

Results

A total of 106 kidney transplant recipients were included in this study. In the analysis of test-retest reliability, Cohen's kappa coefficient was found to be 0.62. In the analysis of measurement error, the positive and negative agreement were 0.78 and 0.84, respectively. In the analysis of concurrent validity with the medication event monitoring system, sensitivity and specificity were 0.84 and 0.90, respectively. In the analysis of concurrent validity with the 12-item Medication Adherence Scale, the point-biserial correlation coefficient for the "medication compliance" subscale was 0.38 (P < 0.001).

Conclusions

The J-BAASIS was determined to have good reliability and validity. Using the J-BAASIS to evaluate adherence can help clinicians to identify medication nonadherence and institute appropriate corrective measures to improve transplant outcomes.

Non-adherence assessment to immunosuppressant therapy with a self-report questionnaire and intra-patient variability in renal transplantation: risk factors and clinical correlations

BACKGROUND

Non-adherence (NA) to immunosuppressive drugs is to date considered a crucial issue in kidney transplanted patients (KTRs), leading to de-novo donor-specific anti-HLA antibodies (dnDSA) development, acute and chronic rejection, and at least graft loss. However, NA assessment is challenging, often leading to underestimation in real-life settings.

METHODS

NA evaluation in all KTRs referred to our post-transplantation clinic in the period between 01/01-15/07/2018 with self-report questionnaire combined to intra-patient variability (IPV) of the pivotal immunosuppressive drug (based on trough levels of tacrolimus/mTOR inhibitor).

RESULTS

Based on both questionnaire and IPV, 86 out of the 504 tested KTRs (17%) were classified as NA. Male gender (OR, 2.0; 95% confidence interval [CI], 1.2 to 3.4), high educational level (OR for KTRs with a degree, 1.8 [95% CI, 1.0 to 3.1]), employment (OR, 2.0 [95% CI, 1.2 to 3.3]), young age at transplantation (P=0.017), longer time on the waiting list and after transplantation (P=0.027 and 0.049 respectively) were all associated with NA. High IPV was mostly documented in KTRs treated with the twice-daily formulation of the immunosuppressive drug (OR, 1.5 [95% CI, 1.0 to 2.1]) and better associated with dnDSA appearance (OR, 2.1 [95% CI, 1.1 to 3.9]).

CONCLUSIONS

NA is a significant problem, difficult to assess, and can lead to dnDSA development also in our population. Identifying risk factors for NA might be an underestimated tool to improve graft and patient outcome in KTRs.

Understanding Health-Related Quality of Life in Kidney Transplant Recipients: The Role of Symptom Experience and Illness Perceptions

The purpose of our article is to investigate the impact of symptom experience on health related quality of life (HRQOL) in kidney transplant recipients (KTRs) and whether illness perceptions mediated this impact. Symptom experience, illness perceptions, and HRQOL were measured at transplantation and 6 weeks after transplantation in KTRs in an ongoing Dutch cohort study. Multivariable linear regression models were used for the analysis. 90 KTRs were analyzed. Fatigue and lack of energy were the most prevalent and burdensome symptoms at transplantation. Mental HRQOL at 6 weeks after transplantation was comparable to that of the general Dutch population (mean [standard deviation, SD]: 49.9 [10.7]) versus 50.2 [9.2]), while physical HRQOL was significantly lower (38.9 [9.1] versus 50.6 [9.2]). Experiencing more symptoms was associated with lower physical and mental HRQOL, and the corresponding HRQOL reduced by -0.15 (95%CI, -0.31; 0.02) and -0.23 (95%CI, -0.42; -0.04) with each additional symptom. The identified mediation effect suggests that worse symptom experiences could cause more unhelpful illness perceptions and consequently lead to lower HRQOL. Illness perceptions may explain the negative impact of symptom experience on HRQOL. Future studies at later stages after kidney transplantation are needed to further explore the mediation effect of illness perceptions and guide clinical practice to improve HRQOL.

Graft Failure Due to Nonadherence among 150 Prospectively-Followed Kidney Transplant Recipients at 18 Years Post-transplant: Our Results and Review of the Literature

Background: We previously reported that graft failure due to nonadherence (GFNA) was a major cause of graft loss in kidney transplantation. Here, among 150 prospectively-followed kidney transplant recipients at 18 years post-transplant, we provide: updated (longer-term) estimates of cause-specific graft loss probabilities, risk factors for developing GFNA, and detailed characterizations of patients’ overt nonadherent (NA) behavior, including timing, extent, and clinical consequences. Methods: Determination of the patient becoming NA in taking his/her immunosuppressive medications, and the underlying cause of graft loss, were determined prospectively by the attending physicians. For never-functioning-graft, GFNA, GF due to causes other than NA (Other GF), and death with a functioning graft (DWFG), cumulative incidence functions were used to estimate the cumulative probabilities of cause-specific graft loss. Cox stepwise regression was used to determine significant multivariable predictors for the hazard rate of developing GFNA. Results: GFNA was a major cause of graft loss (22/150 patients), particularly among African-American and Hispanic recipients <50 years of age-at-transplant (20/56 experienced GFNA), with estimated percentages of such patients ever developing GFNA ranging between 36.9 and 41.5%. These patients were also at a higher risk of developing Other GF. For the remaining patients (2/94 experienced GFNA), estimated percentages of ever-developing GFNA were much lower (range: 0.0−6.7%). The major cause of graft loss among recipients ≥50 years of age was DWFG; GFNA rarely occurred among older recipients. In 21/22 GFNA patients, NA behavior lasted continuously from the time of developing NA until GFNA. In total, 28/150 patients became NA, and 67.9% (19/28) occurred beyond 36 months post-transplant. A total of 25 of 28 NA patients (89.3%) developed biopsy-proven acute rejection and/or chronic rejection that was directly attributed to the NA behavior. Lastly, 25/28 admitted to NA behavior, with financial and psychological components documented in 71.4% (20/28) and 96.4% (27/28) of NA cases, respectively. Conclusions: These results highlight the importance of performing serial monitoring of patients for overt NA behavior throughout their post-transplant follow-up. Financial and psychological components to NA behavior need to be simultaneously addressed with the goal of achieving complete avoidance/elimination of NA behavior among higher risk patients.

Illness Perceptions and Medication Nonadherence to Immunosuppressants After Successful Kidney Transplantation: A Cross-Sectional Study

Background: Medication nonadherence to immunosuppressants is a well-known risk factor for suboptimal health outcomes in kidney transplant recipients (KTRs). This study examined the relationship between illness perceptions and medication nonadherence in prevalent Dutch KTRs and whether this relationship depended on post-transplant time.

Methods: Eligible KTRs transplanted in Leiden University Medical Center were invited for this cross-sectional study. The illness perceptions and medication nonadherence were measured via validated questionnaires. Associations between illness perceptions and medication nonadherence were investigated using multivariable logistic regression models.

Results: For the study, 627 participating KTRs were analyzed. 203 (32.4%) KTRs were considered nonadherent to their immunosuppressants with “taking medication more than 2 h from the prescribed dosing time” as the most prevalent nonadherent behaviour (n = 171; 27.3%). Three illness perceptions were significantly associated with medication nonadherence: illness identity (adjusted odds ratio [OR_adj] = 1.07; 95% confidence interval [CI], 1.00–1.14), concern (OR_adj = 1.07; 95%CI,1.00–1.14), and illness coherence (OR_adj = 1.11; 95%CI,1.01–1.22). The relationships between illness perceptions and medication nonadherence did not differ depending on post-transplant time (p-values ranged from 0.48 to 0.96).

Conclusion: Stronger negative illness perceptions are associated with medication nonadherence to immunosuppressants. Targeting negative illness perceptions by means of psychoeducational interventions could optimize medication adherence and consequently improve health outcomes in KTRs.

Medication, Healthcare Follow-up, and Lifestyle Nonadherence: Do They Share the Same Risk Factors?

Barriers to medication adherence may differ from barriers in other domains of adherence. In this study, we assessed the association between pre-kidney transplantation (KT) factors with nonadherent behaviors in 3 different domains post-KT.

METHODS

We conducted a prospective cohort study with patient interviews at initial KT evaluation (baseline-nonadherence predictors in sociodemographic, condition-related, health system, and patient-related psychosocial factors) and at ≈6 mo post-KT (adherence outcomes: medications, healthcare follow-up, and lifestyle behavior). All patients who underwent KT at our institution and had ≈6-mo follow-up interview were included in the study. We assessed nonadherence in 3 different domains using continuous composite measures derived from the Health Habit Survey. We built multiple linear and logistic regression models, adjusting for baseline characteristics, to predict adherence outcomes.

RESULTS

We included 173 participants. Black race (mean difference in adherence score: -0.72; 95% confidence interval [CI], -1.12 to -0.32) and higher income (mean difference: -0.34; 95% CI, -0.67 to -0.02) predicted lower medication adherence. Experience of racial discrimination predicted lower adherence (odds ratio, 0.31; 95% CI, 0.12-0.76) and having internal locus of control predicted better adherence (odds ratio, 1.46; 95% CI, 1.06-2.03) to healthcare follow-up. In the lifestyle domain, higher education (mean difference: 0.75; 95% CI, 0.21-1.29) and lower body mass index (mean difference: -0.08; 95% CI, -0.13 to -0.03) predicted better adherence to dietary recommendations, but no risk factors predicted exercise adherence.

CONCLUSIONS

Different nonadherence behaviors may stem from different motivation and risk factors (eg, clinic nonattendance due to experiencing racial discrimination). Thus adherence intervention should be individualized to target at-risk population (eg, bias reduction training for medical staff to improve patient adherence to clinic visit).

Retrospective Analysis of Tacrolimus Intrapatient Variability as a Measure of Medication Adherence

Background:

Increased intrapatient variability (IPV) in tacrolimus levels is associated with graft rejection, de novo donor-specific antibodies, and graft loss. Medication nonadherence may be a significant contributor to high IPV.

Objective:

The objective of this study is to determine the utility of tacrolimus IPV in detecting nonadherence by examining the relationship between self-reported adherence and tacrolimus coefficient of variability (COV), a measure of IPV.

Design:

Retrospective cohort study.

Setting:

St. Michael’s Hospital, Toronto, Ontario.

Patients:

All patients who were at least 1-year post-kidney transplant as of March 31, 2019, prescribed tacrolimus as an immunosuppressant and had a self-reported adherence status. Patients were excluded from the primary analysis of examining the correlation between COV and self-reported adherence if they lacked a calculatable COV.

Measurements:

Self-reported adherence, COV, demographic data, transplant, and medication history.

Methods:

A modified Basel Assessment of Adherence to Immunosuppressive Medications Scale (BAASIS) administered by healthcare professionals to assess self-reported adherence was used. The COV of tacrolimus trough levels was calculated and its correlation to BAASIS response was noted. The median COV was used as a cutoff to examine the characteristics of patients deemed “high COV” and “low COV.”

Results:

A total of 591 patients fit the initial criteria; however, only 525 had a recent calculatable COV. Overall, 92.38% of the population were adherent by self-report. Primary analysis identified a COV of 25.2% and 29.6% in self-reported adherent and nonadherent patients, respectively, though the result was not significant (P = .2). Secondary analyses showed a significant correlation between younger age at transplant and at the time of adherence self-reporting with nonadherence (P = .01). In addition, there was a strong correlation between those nonadherent with routine post-transplant blood work and younger age (P < .01).

Limitations:

The limitations included modified nonvalidated BAASIS questionnaire, social desirability bias, BAASIS only administered in English, and patients with graft failure not active in clinic not being captured.

Conclusions:

The COV should not be used as the sole method for determining medication adherence. However, COV may have some utility in capturing individuals who are not adherent to their blood work or patients who are having a poor response to tacrolimus and should be switched to another medication.

Non-Adherence to Appointments is a Strong Predictor of Medication Non-Adherence and Outcomes in Kidney Transplant Recipients

BACKGROUND

Non-adherence is an important aspect of transplantation that affect outcomes. This study aims to investigate the impact of non-adherence to laboratory and clinic appointments on medication non-adherence and outcomes in kidney transplant (KT) recipients.

METHODS

We analyzed KT recipients between 2005-14 with a detailed review of the medical records for non-adherence to laboratory and clinic appointments, as well as medication regimens. Baseline characteristics and clinical outcomes were compared between adherent and non-adherent groups.

RESULTS

A total of 1413 KT recipients were included: 754 who were adherent and 659 who were non-adherent. Non-adherent recipients tend to be younger, African American, and have private insurance. Adherent patients tend to have a history of DM, heart disease, and receive an ECD kidney. Non-adherence to appointments was a strong predictor of medication non-adherence (OR 3.1), acute rejection (OR 1.4), and subsequent rejection episodes (OR 3.3 and 8.1 respectively for ≥ 1 and ≥ 2 rejection episodes). Subset analysis of patients who had early non-adherence within 1-year post-transplant showed predominance of younger, African American patients. The same patients had higher prevalence of medication non-compliance, overall and ≥ 1-year post-transplant, and mean number of readmissions. Kaplan-Meier analysis showed a trend towards lower graft survival in this group.

CONCLUSIONS

Early non-adherence to laboratory and clinic appointments is a strong predictor of late medication non-adherence, acute rejection, and graft loss. Targeting patients that demonstrate early non-adherence to appointments with focused interventions may help improve kidney transplant outcomes in this high risk group.

Development of an Educational Video for Self-Assessment of Patients with RA: Steps, Challenges, and Responses

Objectives:

The primary objective was to develop an educational video to teach patients with rheumatoid arthritis (RA) self-assessment of their disease activity. Secondary objectives were to validate the video, identify the challenges in producing it, and the responses to these challenges.

Methods:

Rheumatologists from 7 Middle Eastern Arab countries (MEAC) discussed unmet needs in the education of patients with RA. They reviewed pre-existing educational audiovisual material and drafted the script for a new video in Arabic. The video was produced in collaboration with a technical team, then validated by patients using a standardized interview. At each step of production, challenges were identified.

Results:

Twenty-three rheumatologists from MEAC identified unmet needs in patients’ education. A video was produced, explaining the concepts of treat-to-target and showing a patient performing self-assessment using DAS-28. Sixty-two patients were interviewed for validation and found the video to be useful and easy to understand, albeit not replacing the physician’s visit. Most common challenges encountered included acceptance of patient empowerment, agreement on DAS-28 as composite measure, production of a comprehensible written Arabic text, and addressing the population cultural mix.

Conclusion:

Despite challenges, the video was well accepted among patients and can be used for clinical and research purposes. It is particularly useful in pandemic periods where social distancing is recommended.

Changes in Beliefs About Post-Transplant Immunosuppressants Over Time and Its Relation to Medication Adherence and Kidney Graft Dysfunction: A Follow-Up Study

PURPOSE

The main aim was to evaluate the changes in beliefs about immunosuppressants over a 3-year period in patients after kidney transplantation. The second aim was to investigate the relationship between beliefs, medication adherence, and selected clinical outcomes such as graft functioning.

PATIENTS AND METHODS

This observational follow-up study was conducted in the outpatient post-transplant clinic at the University Hospital Hradec Kralove in the Czech Republic. Adult patients, at least 4 weeks after kidney transplantation, were invited for the structured interview, which was followed by a self-administered questionnaire survey during their regularly scheduled visits at the clinic. Appropriate paired tests were used to compare two measurements of beliefs about immunosuppressants by BMQ-CZ© in 2016 (baseline) and in 2019 (follow-up). Self-reported adherence was measured by two validated tools (MARS-CZ© and BAASIS©) capturing implementation and discontinuation phases. A generalized linear model was used to investigate the relation between beliefs and the consecutive estimated glomerular filtration rate.

RESULTS

The study involved 134 patients. Over time, their perceived treatment necessity beliefs of immunosuppressants decreased, while their treatment-related concerns increased. Overall self-reported non-adherence (ie, taking, dosing and discontinuation of immunosuppressants) was reported by 12% of the patients in both observation periods. In the follow-up period, timing non-adherence was reported by 52 (38.8%) patients. Higher baseline treatment concerns were associated with poor adherence whereas higher baseline treatment necessity beliefs corresponded with better kidney functioning, even after adjusting for age.

CONCLUSION

Higher treatment necessity beliefs corresponded with better kidney functioning, whereas higher treatment concerns were related to non-adherence to immunosuppressants at the beginning of the observed period. Still, most patients accepted their medicines that do not come without risk. Nevertheless, decreasing treatment necessity beliefs on one hand, and increasing treatment concerns on the other, should be considered in clinical practice.

Comparison of a home-based (multi) systemic intervention to promoting Medication AdheRence and Self-management among kidney transplant recipients with care-as-usual: the MARS randomized controlled trial protocol

Background

After kidney transplantation non-adherence and inadequate self-management undermine clinical outcomes and quality of life. Both have been demonstrated to be substantial in all age groups. However, interventions promoting adherence and self-management among kidney transplant recipients that have proven to be effective are scarce. In this study we aim to develop and test an intervention to optimize adherence and self-management. In this article we describe the background and design of the trial entitled ‘promoting Medication AdheRence and Self-management among kidney transplant recipients’ (MARS-trial)’.

Methods/design

This is a single-center, parallel arm randomized controlled trial. Nonadherent kidney transplant recipients aged 12 years or older are eligible for inclusion. Patients will be randomly assigned to either the experimental or a control group. The control group will receive care-as-usual. The experimental group will receive care-as-usual plus the MARS-intervention. The MARS-intervention is an outreaching intervention, based on the principles of (multi) systemic therapy which means involving the social network. A standardized intervention protocol is used for consistency but we will tailor the behavior change techniques used to the specific needs and determinants of each patient. The primary outcome of medication adherence will be measured using electronic monitoring. Secondary outcome measures regarding medication adherence and self-management are also assessed. Data is collected at baseline (T0), after a run-in period (T1), at six months post-baseline/end of treatment (T2) and after a six month follow-up period (T3).

Discussion

We combined elements of (multi) systemic therapy and evidence-based behavior change techniques to create an outreaching and highly individualized intervention. In this trial we will investigate the impact on medication adherence and self-management after kidney transplantation.

The Clinical Impact of the C0/D Ratio and the CYP3A5 Genotype on Outcome in Tacrolimus Treated Kidney Transplant Recipients

Tacrolimus is metabolized by CYP3A4 and CYP3A5 enzymes. Patients expressing CYP3A5 (in Caucasian patients about 15% of the population but more frequent in African Americans and Asians) have a dose requirement that is around 50% higher than non-expressers to reach the target concentration. CYP3A5 expressers can be considered fast metabolizers. The trough concentration/dose (C₀/D) ratio of tacrolimus has recently been proposed as a prognostic marker for poor outcome after kidney transplantation. Patients with a low C₀/D ratio (also referred to as fast metabolizers) seem to have more tacrolimus-related nephrotoxicity, more BK-viremia, and a lower graft survival. At first sight, the expression of CYP3A5 and a low C₀/D ratio seem to be overlapping factors, both pointing towards patients in whom a higher tacrolimus dose is needed to reach the tacrolimus target concentration. However, there are important differences, and these differences may explain why the impact of the C₀/D ratio on long term outcome is stronger than for CYP3A5 genotype status. Patients with a low C₀/D ratio require a high tacrolimus dose and are exposed to high tacrolimus peak concentrations. The higher peak exposure to tacrolimus (and/or its metabolites) may explain the higher incidence of nephrotoxicity, BK-viremia and graft loss. A potential confounder is the concurrent maintenance treatment of corticosteroids, as steroids are sometimes continued in patients at high immunological risk. Steroids induce the metabolism of tacrolimus via pregnane X receptor mediated increased CYP3A4 expression, resulting in lower tacrolimus C₀/D ratio in high risk patients. Also non-adherence may result in lower C₀/D ratio which is also associated with poor outcome. The C₀/D ratio of tacrolimus does seem to identify a group of patients with increased risk of poor outcome after kidney transplantation. Our recommendation is to monitor tacrolimus peak concentrations in these patients, and if these are high then target slightly lower pre-dose concentrations. Another possibility would be to switch to a prolonged release formulation or to dose the drug more frequently, in smaller doses, to avoid high peak concentrations.

Association between Posttransplant Opioid Use and Immunosuppressant Therapy Adherence among Renal Transplant Recipients

INTRODUCTION

Little is known about the effect of posttransplant opioid use on adherence to immunosuppressant therapy (IST) among adult renal transplant recipients (RTRs).

OBJECTIVE

The aim of this study was to examine the relationship between opioid use and IST adherence among adult RTRs during the first year posttransplant.

METHODS

Longitudinal data were analyzed from a retrospective cohort study examining US veterans undergoing renal transplant from October 1, 2007, through March 31, 2015. Data were collected from the US Renal Data System, Centers for Medicare and Medicaid Services Data (Medicare Part D), and Veterans Affairs pharmacy records. Dose of opioid prescriptions was collected and divided based on annual morphine milligram equivalent within a year of transplant. Proportion of days covered of greater than or equal to 80% indicated adherence to tacrolimus. Unadjusted and multivariable-adjusted logistic regression analyses were performed.

RESULTS

A study population of 1,229 RTRs included 258 with no opioid use, while 971 opioid users were identified within the first year after transplantation. Compared to RTRs without opioid usage, RTRs with opioid usage had a lower probability of being adherent to tacrolimus in unadjusted logistic regression (odds ratio [OR] (95% confidence interval [CI]): 0.22 [0.07-0.72]) and adjusted logistic regression (OR [95% CI]: 0.11 [0.03-0.44]). These patterns generally remained consistent in unadjusted and adjusted main and sensitivity analyses.

CONCLUSIONS

Findings indicate RTRs who use prescription opioids during the first year posttransplant, regardless of the dosage/amount, are less likely to be adherent to tacrolimus. Future studies are needed to better understand underlying causes of the association between opioid use and tacrolimus nonadherence.

Impact of a Mobile Health Intervention on Long-term Nonadherence After Lung Transplantation: Follow-up After a Randomized Controlled Trial

BACKGROUND

In a randomized controlled trial, lung transplant recipients (LTRs) using a mobile health intervention, Pocket Personal Assistant for Tracking Health (Pocket PATH), showed better adherence to the medical regimen than LTRs receiving usual care during the first year posttransplant. We examined whether these effects were maintained beyond the end of the trial and evaluated other potential risk factors for long-term nonadherence.

METHODS

Adherence in 8 areas was evaluated at follow-up in separate LTR and family caregiver (collateral) assessments. Pocket PATH and usual care groups' nonadherence rates were compared; multivariable regression analyses then examined and controlled for other patient characteristics' associations with nonadherence.

RESULTS

One hundred five LTRs (75% of survivors) were assessed (M = 3.9 years posttransplant, SD = 0.8). Nonadherence rates in the past month were 23%-81% for self-care and lifestyle requirements (diet, exercise, blood pressure monitoring, spirometry), 13%-23% for immunosuppressants and other medications, and 4% for tobacco use, with 31% clinic appointment nonadherence in the past year. In multivariable analysis, the Pocket PATH group showed lower risk of nonadherence to lifestyle requirements (diet/exercise) than the usual care group (P < 0.05). Younger age and factors during the first year posttransplant (acute graft rejection, chronically elevated anxiety, less time rehospitalized, nonadherence at the final randomized controlled trial assessment) were each associated with nonadherence in at least 1 area at follow-up (P < 0.05).

CONCLUSIONS

Pocket PATH did not have sustained impact on most areas of the regimen, although we identified other risk factors for long-term nonadherence. Future work should explore strategies to facilitate sustained effects of mobile health interventions.

Adherence profiles in kidney transplant patients: Causes and consequences

OBJECTIVE

Adherence is a dynamic phenomenon and a critical determinant of transplant patients outcome. The objective of this longitudinal study was to explore adherence in kidney transplant patients followed-up for up to three years after transplantation.

METHODS

Adherence was repeatedly estimated using the Morisky-Green-Levine 4-Item Medication Adherence Scale, in two successive cohorts of 345 (EPIGREN) and 367 (EPHEGREN) kidney transplant recipients. Mixed effect modeling with latent processes and latent classes was used to describe adherence time-profiles.

RESULTS

Two latent classes were identified. The adherent class represented 85% of the patients. Patients of the poorer-adherence class displayed a lower adherence at one month (p<10^-3), which worsened over time. Good adherence was associated with age >50 years, fewer depression episodes (5% vs. 13%, p = 0.001) and a better mental health component of quality of life (MCS-SF36 47 ± 11 vs. 41 ± 13, p = 0.015). Survival without acute rejection episodes was longer in the adherent class (p = 0.004).

CONCLUSIONS

The risk of poor adherence in renal transplant patients can be detected as early as one month post-transplantation, using appropriate and easy tools adapted to routine monitoring.

PRACTICE IMPLICATIONS

An early focus on vulnerable patients should allow putting into place actions in order to reduce the risk of poor outcome related to poor adherence.

Medication nonadherence after kidney transplantation: an internet-based survey in Japan

Nonadherence to immunosuppressive medications after kidney transplantation is a major risk factor for allograft rejection and graft loss. Transplant recipients tend to conceal nonadherence in clinical settings. We conducted an internet-based cross-sectional survey aimed to clarify the prevalence and risk factors of patient nonadherence after kidney transplantation in Japan. The Basel Assessment of Adherence to Immunosuppressive Medication Scale (BAASIS©) was used to detect nonadherence. In this survey, patients were asked about their relationship with medical staff and their self-efficacy for taking medication, along with other questions. A total of 219 kidney transplant recipients were included in the analysis. Ninety-four demonstrated nonadherence (42.7%). The following factors were associated with nonadherence: short dialysis period prior to transplantation; undergoing transplantation at least twice; male sex; lack of satisfaction with the explanation of immunosuppressive medication; and absence of medical staff to consult upon forgetting to take drugs. The nonadherence group reported low self-efficacy for medication in many settings. This anonymous survey provides valuable insight into the actual nonadherence rate, factors associated with nonadherence, and life situations that may complicate medication-taking.

High Calcineurin Inhibitor Intrapatient Variability Is Associated With Renal Allograft Inflammation, Chronicity, and Graft Loss

Background

High calcineurin inhibitor (CNI) intrapatient variability (IPV) has been associated with poor kidney allograft outcomes. However, the relationship between early allograft histological changes, their progression, and CNI-IPV is less well studied. Hence, we evaluated effect of CNI-IPV defined by the degree of fluctuation of CNI levels in all kidney transplant patients over 2 to 12 months posttransplant on early allograft inflammation, subsequent chronicity, and later clinical outcomes.

Methods

Two hundred eighty-six patients transplanted from January 2013 to November 2014 were enrolled with protocol and indication biopsies. The mean CNI-IPV was 28.5% and a quarter of our cohort had IPV of 35% or greater (high CNI IPV). Baseline demographic differences were similar between high and low CNI IPV groups.

Results

High CNI-IPV was associated with a higher incidence of acute rejection (AR) within 1 year (52% vs 31% P < 0.001), more persistent/recurrent AR by 1 year (18.2% vs 6.2%, P = 0.002), higher-grade AR (≥Banff 1B, 27.5% vs 7.3%, P < 0.001), and worse interstitial fibrosis/tubular atrophy (P = 0.005). High CNI-IPV was associated with increased graft loss (GL) and impending graft loss (iGL, defined as eGFR<30 ml/min and >30% decline in eGFR from baseline), regardless of donor-specific antibody, delayed graft function, rejection, or race. In a multivariate Cox Proportional Hazards Model, high CNI-IPV was independently associated with GL + iGL (hazard ratio, 3.1; 95% confidence interval, 1.6-5.9, P < 0.001).

Conclusions

High CNI-IPV within 1 year posttransplant is associated with higher incidence of AR, severe AR, allograft chronicity, GL, and iGL. This represents a subset of patients who are at risk for poor kidney transplant outcomes and potentially a modifiable risk factor for late allograft loss.

Prevalence and Risk Factors of Immunosuppressant Nonadherence in Heart Transplant Recipients: A Single-Center Cross-Sectional Study

BACKGROUND

Immunosuppressant nonadherence (INA) has been shown to affect outcomes after solid organ transplantation. The aim of the present study was to determine the prevalence of INA in heart transplant recipients and the associated risk factors of INA.

METHODS

Adult heart transplant recipients who firstly received heart transplantation (discharged for at least 3 months) were consecutively enrolled. Immunosuppressant adherence was assessed using the Basel Assessment of Adherence with Immunosuppressive Medication Scale (BAASIS). INA was categorized into five domains of contributing factors (socio-demographic factors, transplant-related factors, healthcare system access factors, post-transplant treatment-related factors, and patient-related psychosocial factors). These factors were compared between adherent and nonadherent patients. The risk factors of INA were investigated by logistic regression analysis.

RESULTS

A total of 168 heart recipients were ultimately included. Among them, 69 (41.1%) recipients were revealed to be nonadherent. Logistic regression analysis indicated that INA was associated with monthly income<3000 Chinese Yuan (CNY) (OR, 3.11; 95% CI, 1.58-6.12; p=0.001), number of prescribed concomitant drugs (OR, 1.23; 95% CI, 1.12-1.50; p=0.003) and concerns about immunosuppressants (OR, 1.09; 95% CI, 1.01-1.18; p=0.031).

CONCLUSIONS

Heart recipients had a high prevalence of INA. Lower income, greater number of prescribed concomitant drugs, and more concerns about immunosuppressants correlated most with timing nonadherence and taking nonadherence among heart recipients. These findings will be helpful to intervene on and prevent future INA of heart recipients.

Clinic Nonattendance Is a Risk Factor for Poor Kidney Transplant Outcomes

BACKGROUND

The aim of this study was to analyze the impact of clinic nonattendance within the first year after kidney transplantation on graft-related outcomes.

METHODS

Our retrospective analysis included all patients receiving their transplant (2007-2017) and receiving their long-term follow up at our center. Clinic nonattendance was extracted from electronic patient records and informatics systems, with highest clinic nonattenders stratified at the 75th percentile.

RESULTS

Data were analyzed for 916 kidney allograft recipients, with median follow up 1168 days (interquartile range, 455-2073 days). Median number of missed transplant clinic visits in the first year was 5 (interquartile range, 3-7) and nonattenders were defined above the 75th percentile. Nonattenders versus attenders were more likely to be black, ABO-incompatible, repeat kidney transplant recipients but less likely to have pretransplantation diabetes. Nonattenders versus attenders had longer hospital stays after their transplant surgery in days (14.4 vs 12.2 respectively, P = 0.007), higher rate of delayed graft function (21.3% vs 12.8% respectively, P = 0.005), higher risk for 1-year rejection (12.5% vs 7.8% respectively, P = 0.044), worse 1-year estimated glomerular filtration rate in mL/min (47.0 vs 54.1, respectively, P = 0.002) and increased risk for death-censored graft loss by median follow (17.5% vs 12.0%, respectively, P = 0.013). In a Cox regression model, kidney transplant recipients defined as clinic nonattenders within the first postoperative year demonstrated a significantly increased rate of death-censored graft loss (hazard ratio, 1.983; 95% confidence interval, 1.061-3.707; P = 0.032).

CONCLUSIONS

Kidney transplant recipients in the top quartile for nonattendance require additional support and supervision to help attenuate long-term risks to their graft function and survival.

Demographic and Psychological Factors Associated with Feelings of Antibiotic Entitlement in New Zealand

Patients' expectations of being prescribed antibiotics can have an important influence on inappropriate prescribing. Therefore, it is important to understand the drivers of patients' antibiotic expectations. The 2015/16 New Zealand Attitudes and Values Study measured sense of entitlement to antibiotics in a nationally representative sample of New Zealanders (n = 13,484). Participants were asked to rate their agreement with the statement "If I go to my doctor/GP with a minor illness (e.g., sore throat, cough, runny nose, etc.), I think that I should be prescribed antibiotics by default." Eighty percent of participants showed low feelings of antibiotic entitlement, while 18.5% exhibited moderate and 3.7% high feelings of entitlement. People of ethnic minority, lower socio-economic status, and with diabetes expressed higher expectations of being prescribed antibiotics. This may be partially based on a higher risk of rheumatic fever or other complications. Men, religious people, those with lower educational attainment and self-rated health, but greater psychological distress and feelings of control over their health exhibited higher feelings of antibiotic entitlement. Those high on Extraversion, Conscientiousness, and Narcissism, but low on Agreeableness and Openness, also showed greater feelings of entitlement. Our findings help identify key characteristics of those more likely to express inappropriate expectations of antibiotic prescription.

Development of a patient-centered video series to improve education before kidney transplantation

BACKGROUND

Inadequate patient knowledge about transplantation can result in low patient satisfaction and contribute to poor clinical outcomes. The purpose of this patient-oriented research project was to develop an educational intervention for patients awaiting kidney transplantation.

METHODS

An educational intervention was developed by patients and health care providers, experts in medication adherence, video education, motivational psychology, and cultural education. Project objectives were defined and content was guided by a series of studies conducted with stakeholders. A review process was undertaken with additional patients, external health care providers and ninth grade high school students and edits were applied accordingly.

RESULTS

A set of six educational videos, ranging in length from 3 to 24 min, was created to describe the transplant process. The videos are patient friendly in design, and incorporate animations to explain complex information to accommodate low health literacy, and patient testimonials align the content with principles of adult learning theory. Feedback from external patient reviews [n = 8], external care providers [n = 13] and students [n = 26], indicate that the mini-series is informative and useful.

CONCLUSION

Patient involvement significantly influenced the development of a video series about kidney transplantation.

PRACTICE IMPLICATIONS

Patient engagement is integral for developing high quality and relevant educational interventions.

Immunosuppression Adherence in Stable Kidney Transplant Patients Converted From Immediate- to Prolonged-Release Tacrolimus in Clinical Practice: A Norwegian Study

Background

This study investigated medication adherence in kidney transplant patients (KTPs) converted from immediate-release tacrolimus (IR-T) to prolonged-release tacrolimus (PR-T)-based immunosuppression in routine practice.

Methods

Noninterventional, observational, multicenter study in Norway. Included adult KTPs with stable graft function, converted from IR-T (baseline) to PR-T (1 mg:1 mg) in routine practice. Data were collected at baseline, and months 1, 3, 6, and 12 postconversion. Primary endpoint: adherence using the Basel Assessment of Adherence to Immunosuppressive Medication Scale. Secondary assessments: tacrolimus dose and trough levels (target, 3-7 ng/mL), clinical laboratory parameters (eg, estimated glomerular filtration rate [Modified Diet in Renal Disease]), and adverse events.

Results

Ninety-one KTPs (mean ± SD age 47.7 ± 14.3 years) were analyzed. Mean ± SD change in PR-T dose from baseline (4.4 ± 2.4 mg/d) to month 12 was −0.1 ± 0.9 mg/d; mean tacrolimus trough levels remained within target. Overall medication adherence increased from 45.6% at baseline to 58.1% at month 1, but was similar to baseline thereafter; taking and timing adherence followed a similar pattern. Odds ratio (OR) for adherence at month 1 (but not at other time points) was greater versus baseline for overall (OR, 1.71; P = 0.0205), taking (OR, 3.38; P = 0.0004), and timing (OR, 1.77, P = 0.0252) dimensions. Mean ± SD Basel Assessment of Adherence to Immunosuppressive Medication Scale visual analogue scale score at baseline was 96.4 ± 5.5%, and increased postconversion. Estimated glomerular filtration rate remained stable (month 12, 61.6 ± 17.7 mL/min per 1.73 m²), as did other laboratory parameters. Two (2.2%) patients had adverse events considered probably/possibly treatment-related.

Conclusions

There was disparity between high, patient-perceived and low, actual adherence. Converting stable KTPs from IR-T to PR-T in routine practice did not impact long-term adherence to immunosuppression; renal function remained stable.

Trajectory of adherence behavior in pediatric and adolescent liver transplant recipients: The medication adherence in children who had a liver transplant cohort

Knowledge of the longterm trajectory of nonadherence to immunosuppressants can inform decisions regarding organ allocation, adherence monitoring, and intervention efforts. The Medication Adherence in Children Who Had a Liver Transplant (MALT) prospective multisite study followed 400 pediatric and adolescent liver transplant recipients for 2 years, using the Medication Level Variability Index to monitor adherence. We hypothesized that adherence is an unstable (fluctuating) phenomenon: that patients who are adherent in year 1 may become nonadherent in year 2, and vice versa. However, we also hypothesized that a majority (more than 50%) of nonadherent patients remain nonadherent over time. We further hypothesized that the longer nonadherence lasts, the higher the likelihood of adverse events (rejection). Finally, we explored the effect of socioeconomic factors on the evolution of adherence over time. Most (59.7%) of the MALT patients who were nonadherent in year 1 remained so in year 2; 18.5% of patients who were adherent in year 1 became nonadherent in year 2. Only 4.4% of patients who were adherent in both year 1 and year 2 had a rejection, compared with 22.9% of patients who were nonadherent during 1 of the years, and 34.9% of those who were nonadherent in both years (P < 0.001), establishing a "dose-dependent" effect of adherence on transplant outcomes. Single-parent households were associated with worsening adherence. Our results suggest that good baseline adherence does not guarantee adherence later on, that nonadherence is likely to persist in the absence of interventions, and that monitoring of adherence and interventions to improve it should be expected to last for years if transplant outcomes are to be improved.

High Intrapatient Variability of Tacrolimus Levels and Outpatient Clinic Nonattendance Are Associated With Inferior Outcomes in Renal Transplant Patients

Supplemental digital content is available in the text.

Background

Nonadherence to immunosuppressants is associated with rejection and allograft loss. Intrapatient variability (IPV) of immunosuppression levels is a marker of nonadherence. This study describes the impact of IPV of tacrolimus levels in patients receiving a tacrolimus monotherapy immunosuppression protocol.

Methods

We retrospectively analyzed the outpatient tacrolimus levels of kidney-only transplant patients taken between 6 and 12 months posttransplant. IPV was determined using the coefficient of variance.

Results

Six hundred twenty-eight patients with a mean number of 8.98 ± 3.81 tacrolimus levels and a mean follow-up of 4.72 ± 2.19 years were included. Multivariate analysis showed death was associated with increasing age (1.04 [1.01-1.07], P = 0.0055), diabetes at time of transplant (2.79 [1.44-5.41], P = 0.0024), and rejection (2.34 [1.06-5.19], P = 0.036). Variables associated with graft loss included the highest variability group (2.51 [1.01-6.27], P = 0.048), mean tacrolimus level less than 5 ng/mL (4.32 [1.94-9.63], P = 0.0003), a high clinic nonattendance rate (1.10 [1.01-1.20], P = 0.03), and rejection (9.83 [4.62-20.94], P < 0.0001). Independent risk factors for rejection were de novo donor-specific antibody (3.15 [1.84-5.39], P < 0.0001), mean tacrolimus level less than 5 ng/mL (2.57 [1.27-5.19], P = 0.00860, and a high clinic nonattendance rate (1.11 [1.05-1.18], P = 0.0005).

Conclusions

This study shows that high tacrolimus IPV and clinic nonattendance are associated with inferior allograft survival. Interventions to minimize the causes of high variability, particularly nonadherence are essential to improve long-term allograft outcomes.

Efficacy of interventions for adherence to the immunosuppressive therapy in kidney transplant recipients: a meta-analysis and systematic review

Immunosuppressive treatment regimens are complex and require ongoing self-management. Medication adherence can be difficult to achieve for several reasons. The current meta-analysis and systematic review investigated whether adherence interventions improved immunosuppressive treatment adherence in kidney transplant recipients. Medline, Cochrane, EMBASE, and Google Scholar were searched until October 17, 2016 using the following search terms: kidney transplantation, compliance, adherence, and immunosuppressive therapy. Randomized controlled trials and two-arm prospective, retrospective, and cohort studies were included. The primary outcomes were adherence rate and adherence score. Eight studies were included with a total for 546 patients. Among participants receiving intervention, the adherence rate was significantly higher than the control group (pooled OR=2.366, 95% CI 1.222 to 4.578, p=0.011). Participants in the intervention group had greater adherence scores than those in the control group (pooled standardized difference in means =1.706, 95% CI 0.346 to 3.065, p=0.014). Sensitivity analysis indicated that findings for adherence rate were robust. However, for adherence score, the significance of the association disappeared after removing one of the studies indicating the findings may have been overly influenced by this one study. Intervention programs designed to increase immunosuppressive adherence in patients with kidney transplant improve treatment adherence.

Practical Recommendations for Long-term Management of Modifiable Risks in Kidney and Liver Transplant Recipients: A Guidance Report and Clinical Checklist by the Consensus on Managing Modifiable Risk in Transplantation (COMMIT) Group

Short-term patient and graft outcomes continue to improve after kidney and liver transplantation, with 1-year survival rates over 80%; however, improving longer-term outcomes remains a challenge. Improving the function of grafts and health of recipients would not only enhance quality and length of life, but would also reduce the need for retransplantation, and thus increase the number of organs available for transplant. The clinical transplant community needs to identify and manage those patient modifiable factors, to decrease the risk of graft failure, and improve longer-term outcomes.COMMIT was formed in 2015 and is composed of 20 leading kidney and liver transplant specialists from 9 countries across Europe. The group's remit is to provide expert guidance for the long-term management of kidney and liver transplant patients, with the aim of improving outcomes by minimizing modifiable risks associated with poor graft and patient survival posttransplant.The objective of this supplement is to provide specific, practical recommendations, through the discussion of current evidence and best practice, for the management of modifiable risks in those kidney and liver transplant patients who have survived the first postoperative year. In addition, the provision of a checklist increases the clinical utility and accessibility of these recommendations, by offering a systematic and efficient way to implement screening and monitoring of modifiable risks in the clinical setting.

Patterns of Personality in Living Kidney Donors

BACKGROUND

The decision to undergo living donor transplantation determines a particular condition characterized by strong mental and emotional anguish, both for the patient and his family. Many recent studies showed the concern of living donors who, rather than being driven by altruistic reasons, meet the decision to donate with ambivalence, liabilities, and/or in response to family pressures. The aim of this study was to analyze the more frequently encountered personality variables in a sample of potential kidney living donors, together with any psychological variables that can express possible risks of an impulsive decision and/or poorly processed from a cognitive and emotional point of view.

METHODS

We examined 32 potential kidney donors. The personality study was performed using The Millon Clinical Multiaxial Inventory-III. The psychic symptoms were studied through the Symptom Checklist-90-R. The quality of life was studied through the Complete Form Health Survey (SF-36).

RESULTS

The study showed that the ability to express free and therefore invalid consent, in the role of donor, is an expression of specific personality patterns, cognitive, emotional aspects and interpersonal experiences.

CONCLUSIONS

The psychological-psychiatric evaluation of potential donors is fundamental to certify the state of mental health and psychological well-being, an indispensable prerequisite for the donation.

Automated Reminders and Physician Notification to Promote Immunosuppression Adherence Among Kidney Transplant Recipients: A Randomized Trial

BACKGROUND

Immunosuppression nonadherence increases the risk for kidney transplant loss after transplantation. Wireless-enabled pill bottles have created the opportunity to monitor medication adherence in real time. Reminders may help patients with poor memory or organization. Provision of adherence data to providers may motivate patients to improve adherence and help providers identify adherence barriers.

STUDY DESIGN

Randomized controlled trial.

SETTING & PARTICIPANTS

Kidney transplant recipients (n=120) at a single center.

INTERVENTION

Participants were provided wireless pill bottles to store tacrolimus and record bottle openings. Participants were randomly assigned 1:1:1 to adherence monitoring with customized reminders (including alarms, texts, telephone calls, and/or e-mails), monitoring with customized reminders plus provider notification (every 2 weeks, providers received notification if adherence decreased to <90% during that period), or wireless pill bottle use alone (control).

OUTCOMES

The main outcome was bottle-measured tacrolimus adherence during the last 90 days of the 180-day trial. A secondary outcome was tacrolimus whole-blood concentrations at routine clinical visits.

MEASUREMENTS

Adherence for the primary outcome was assessed via wireless pill bottle openings.

RESULTS

Mean participant age was 50 years; 60% were men, and 40% were black. Mean adherence was 78%, 88%, and 55% in the reminders, reminders-plus-notification, and control arms (P<0.001 for comparison of each intervention to control). Mean tacrolimus levels were not significantly different between groups.

LIMITATIONS

The study did not assess clinical end points. Participants and study coordinators were not blinded to intervention arm.

CONCLUSIONS

Provider notification and customized reminders appear promising in helping patients achieve better medication adherence, but these strategies require evaluation in trials powered to detect differences in clinical outcomes.

The Impact of Health Care Appointment Non-Adherence on Graft Outcomes in Kidney Transplantation

BACKGROUND

Non-adherence to medication is a well-studied and known cause of late allograft loss, but it is difficult to measure and prospectively monitor. The aim of this study was to assess if appointment non-adherence was correlated with medication non-adherence and a predictor of graft outcomes.

METHODS

This was a longitudinal cohort study that used the National United States Renal Data System and veterans affairs health records data with time-to-event analyses conducted to assess the impact on graft and patient survival.

RESULTS

The number of transplants that were included in the analysis was 4,646 (3,656 with complete records); 14.6% of patients had an appointment no show rate of ≥12% (non-adherence). Appointment and medication non-adherence were highly correlated and both were significant independent predictors of outcomes. Those with appointment non-adherence had 1.5 times the risk of acute rejection (22.0 vs. 14.7%, p < 0.0001) and a 65% higher risk of graft loss (adjusted hazards ratio (aHR) 1.65, 95% CI 1.38-1.97, p < 0.0001). There was a significant interaction between appointment and medication non-adherence; those with appointment and medication non-adherence were at very high risk of graft loss (aHR 4.18, 95% CI 3.39-5.15, p < 0.0001), compared to those with only appointment non-adherence (aHR 1.39, 95% CI 0.97-2.01, p = 0.0766) or only medication non-adherence (aHR 2.44, 95% CI 2.11-2.81, p < 0.0001).

CONCLUSION

These results demonstrate that non-adherence to health care appointments is a significant and independent risk factor for graft loss.

Can illness beliefs, from the common-sense model, prospectively predict adherence to self-management behaviours? A systematic review and meta-analysis

OBJECTIVE

To determine whether people's beliefs about their illness, conceptualised by the common sense model (CSM), can prospectively predict adherence to self-management behaviours (including, attendance, medication, diet and exercise) in adults with acute and chronic physical illnesses.

DESIGN AND MAIN OUTCOME MEASURES

Electronic databases were searched in September 2014, for papers specifying the use of the 'CSM' in relation to 'self-management', 'rehabilitation' and 'adherence' in the context of physical illness. Six hundred abstracts emerged. Data from 52 relevant studies were extracted. Twenty-one studies were meta-analysed, using correlation coefficients in random effects models. The remainder were descriptively synthesised.

RESULTS

The effect sizes for individual illness belief domains and adherence to self-management behaviours ranged from .04 to .13, indicating very weak, predictive relationships. Further analysis revealed that predictive relationships did not differ by the: type of self-management behaviour; acute or chronic illness; or duration of follow-up.

CONCLUSION

Individual illness belief domains, outlined by the CSM, did not predict adherence to self-management behaviours in adults with physical illnesses. Prospective relationships, controlling for past behaviour, also did not emerge. Other factors, including patients' treatment beliefs and inter-relationships between individual illness beliefs domains, may have influenced potential associations with adherence to self-management behaviours.

Physician reported adherence to immunosuppressants in renal transplant patients: Prevalence, agreement, and correlates

OBJECTIVE

Adherence to immunosuppressants (IS) is crucial to prevent allograft rejection. Even though there is evidence that non-adherence to IS among kidney transplant recipients is common, it is rarely routinely assessed in clinical practice. Especially, little is known about how physicians estimate patients' adherence to IS medication.

METHODS

In a single center, cross-sectional study adult patients at least 1 year after kidney transplantation were asked to complete measures of adherence (BAASIS©, Transplant Effect Questionnaire) and of general psychopathology (anxiety, depression, perceived social support). Also the physicians were asked to estimate their patients' adherence. Medical data (time since transplantation, treatment for rejection, IS serum trough levels and target levels) were taken from the patients' charts.

RESULTS

Physicians rated 22 of 238 (9.2%) patients as non-adherent. Physicians' estimations of non-adherence were lower compared to the results of the self-ratings and biopsy-proven rejections. No association was found between physicians' estimates and the variability of IS through levels. Significantly more women and patients who reported that their native language was not German were rated as non-adherent by the physicians. Also, physician-rated non-adherent patients reported significantly higher depression and anxiety scores as well as less social support compared to adherent patients.

CONCLUSION

Our results suggest that physicians tend to underestimate patient non-adherence to IS medication. They appear to use observable cues such as sex, language skills, and elevated anxiety and depression scores in particular, to make inferences about an individual patient's adherence. Underestimation of medication non-adherence may impede physicians' ability to provide high quality care.

Psychiatric aspects of organ transplantation and donation

PURPOSE OF REVIEW

Psychiatrists and other mental health professionals typically assist with evaluating and treating psychiatric and behavioral issues in transplant candidates, recipients, and living organ donors. In this review recent findings on specific psychiatric issues in adult solid organ transplant candidates and recipients, as well as living donors are discussed as well as their relevance to clinical practice.

RECENT FINDINGS

Patients with complex mental health and addiction histories can have outcomes similar to patients without these disorders but may require specialized pretransplant preparation or posttransplant interventions to optimize their outcomes. Specific attention to the preparation and wellbeing of living donors is needed.

SUMMARY

As transplant programmes increasingly consider patients with complex mental health histories, psychiatrists, and mental health professionals evaluating and treating these patients need to consider plans for early identification and treatment. Psychiatric care provided across the preoperative to postoperative periods will best address the longitudinal care needs of patients with mental health disorders. Abstinence from substances and complete adherence to medical directives provides the best chance for optimal outcomes. Treatment of depression may improve transplant outcomes. Research is needed to identify effective interventions and the best strategies to engage patients to improve adherence.

Social Support, Stigma and Disclosure: Examining the Relationship with HIV Medication Adherence among Ryan White Program Clients in the Mid-South USA

Social support from friends and family is positively related to better health outcomes among adults living with HIV. An extension of these networks such as religious communities may be an untapped source of social support for promoting HIV medical adherence. This paper explores the association of HIV medication adherence to satisfaction with support from family, friends and church members, as well as HIV-related stigma, and HIV disclosure. In partnership with the Shelby County Health Department, the Memphis Ryan White Part A Program, and the University of Memphis School of Public Health, a total of 286 interviewer-administered surveys were conducted with Ryan White clients. Seventy-six percent (n = 216) of participants reported being prescribed antiretroviral medication (ARVs). Nearly all participants (n = 202, 94%) prescribed ARVs reported disclosing their HIV status to someone. Almost 20% (n = 40) of those prescribed ARVs reported not being satisfied with support received from his/her church. Interestingly, participants reported rarely experiencing stigma as a result of their HIV status. The extent to which satisfaction with support from personal networks and institutional settings like the church affect medication adherence is yet to be understood. The complexity of HIV disclosure and HIV stigma in relation to these supports warrants further investigation to understand how best to improve HIV health outcomes.
