Transition of care: lessons from the Standardizing Care to Improve Outcomes in Pediatric End Stage Renal Disease (SCOPE) dialysis collaborative.

BACKGROUND: Acknowledging the importance of preparing the pediatric dialysis patient for successful transfer to adult providers, centers from the Standardizing Care to Improve Outcomes in Pediatric End Stage Renal Disease (SCOPE) Dialysis Collaborative developed transition tools and performed iterative implementation of a transition of care (TOC) program to gain real-life insight into drivers and barriers towards implementation of a transition program for patients receiving dialysis. METHODS: A TOC innovation workgroup was developed in 2019 from within SCOPE Collaborative that developed nine educational modules, along with introductory letter and assessment tool to be utilized by SCOPE centers. A 4-month pilot implementation study among six centers of varying patient population (age ≥ 11 years) was performed. TOC tools were further refined, and broader implementation within the collaborative was performed. Interim assessment of TOC tool utilization and implementation success was performed among 11 centers, as a foundation towards broader discussion regarding process, barriers, and success towards TOC implementation among 26 centers. RESULTS: Transition champion was a key driver of successful implementation, and lack of institutional support and collaboration with adult dialysis centers were important barriers towards sustainability. COVID pandemic and increased staff turnover affected longer term implementation of TOC program. CONCLUSIONS: Successful transition and transfer of adolescents/young adults with kidney failure on dialysis remains a challenge. This study represents the experience of the largest cohort of pediatric dialysis centers, with diversity in population size and geography, towards development and implementation of a TOC program. This adds to the resources available to assist centers towards transition and transfer, with particular focus on transitioning patients on dialysis.

Medication adherence in youths with CKD: habits for success.

BACKGROUND: Poor adherence habits are key contributors to nonadherence but there are few clinically feasible methods for evaluating adherence habits, particularly for youths with chronic kidney disease (CKD). This study investigated how participants' qualitative responses to three interview questions about adherence habits mapped to primary principles of habit formation and objectively measured medication adherence in youths with CKD. METHODS: Participants (ages 11-21 years) were recruited from a pediatric nephrology clinic as part of a larger study. Participants' daily objective antihypertensive medication adherence was measured with an electronic pill bottle over a 4-week baseline period. Qualitative interviews about adherence habits and routines were conducted with a subset of participants (N = 18). RESULTS: Clear qualitative differences emerged in how participants with high-medium adherence (80-100%) discussed adherence habits compared to participants with low adherence (0-79%). Participants with high-medium adherence discussed situational cues for taking medicine, including locations that cue adherence, step-by-step events leading up to taking medicine, and people who cue adherence. Participants with high-medium adherence regularly described taking medicine as "automatic," "second nature," and a "habit." Participants with low adherence rarely discussed these habit features nor did they explicitly acknowledge currently missing doses. Participants with low adherence tended to discuss challenges with organization and routines for taking medicine. CONCLUSIONS: Evaluating patient responses to questions about adherence habits may uncover challenges with adherence habit formation, provide direction for habit-strengthening intervention focused on developing automatic cues for taking medication, and support adherence successes for youths with CKD.

Health Care Transition in Adolescents and Young Adults With Chronic Kidney Disease: Focus on the Individual and Family Support Systems.

Health care transition (HCT) from pediatric to adult-focused services is a longitudinal process driven by the collaboration and interactions of adolescent/young adult patients, their families, providers, health care agencies, and environment. Health care providers in both pediatric and adult-focused settings must collaborate, as patients' health self-management skills are acquired in the mid-20s, after they have transferred to adult-focused care. Our manuscript discusses the individual and family support systems as they relate to adolescents and young adults with chronic or end-stage kidney disease. In the individual domain, we discuss demographic/socioeconomic characteristics, disease complexity/course, cognitive capabilities, and self-management/self-advocacy. In the family domain, we discuss family composition/culture factors, family function, parenting style, and family unit factors. We provide a section dedicated to patients with cognitive and developmental disability. Furthermore, we discuss barriers for HCT preparation and offer solutions as well as activities for HCT preparation.

Agreement between attended home and ambulatory blood pressure measurements in adolescents with chronic kidney disease.

BACKGROUND: This study aimed to compare attended home blood pressure (BP) measurements (HBPM) with ambulatory BP monitor (ABPM) readings and examine if level of agreement between measurement modalities differs overall and by subgroup. METHODS: This was a secondary analysis of data from a 2-year, multicenter observational study of children 11-19 years (mean 15, SD = 2.7) with chronic kidney disease. Participants had 3 standardized resting oscillometric home BPs taken by staff followed by 24-h ABPM within 2 weeks of home BP. BP indices (measured BP/95%ile BP) were calculated for mean triplicate attended HBPM and mean ABPM measurements. Paired HBPM and ABPM measurements taken during any of 5 study visits were compared using linear regression with robust standard errors. Generalized estimating equation-based logistic regression determined sensitivity, specificity, negative, and positive predictive values with ABPM as the gold standard. Analyses were conducted for the group overall and by subgroup. RESULTS: A total of 103 participants contributed 251 paired measurements. Indexed systolic BP did not differ between HBPM and daytime APBM (mean difference - 0.002; 95% CI: - 0.006, 0.003); the difference in indexed diastolic BP was minimal (mean difference - 0.033; 95% CI: - 0.040, - 0.025). Overall agreement between HBPM and 24-h ABPM in identifying abnormal BP was high (81.8%). HBPM had higher sensitivity (87.5%) than specificity (77.4%) and greater negative (89.8%) than positive (73.3%) predictive value, and findings were consistent in subgroups. CONCLUSIONS: Attended HBPM may be reasonable for monitoring BP when ABPM is unavailable. The greater accessibility and feasibility of attended HBPM may potentially help improve BP control among at-risk youth.

Empowering patients to adhere to their treatment regimens: A multifaceted approach.

It is well-recognized that adolescence and early adulthood are a high-risk period for non-adherence with treatment regimens in solid organ transplant recipients, leading to high rates of rejection and graft loss (Transplantation, 92, 2011, 1237; Pediatr Transplant, 9, 2005, 381; Transplantation, 77, 2004, 769). Preventing medication non-adherence is the holy grail of transplant adolescent care. If we can determine how best to support our patients in taking their daily medications as prescribed, we can improve long-term health, reduce need for re-transplantation, and reduce healthcare costs. In the last few years, several studies have provided us with additional insights into potentially effective interventions and have highlighted existing gaps in knowledge. This article reviews recent literature published over the last 5 years on the topic of adherence in transplant recipients, highlighting insights and opportunities to promote adherence at the individual patient level, family level, healthcare system level, and community level. Above all, the recent work that is highlighted suggests that adherence interventions for prevention and treatment must be multifaceted, individualized, and longitudinal to be effective.

Engagement and Affective Communication During Pediatric Nephrology Clinic Visits: Associations with Medication Adherence.

OBJECTIVE: To evaluate whether engagement and affective communication among adolescents and young adults (AYAs) with chronic kidney disease (CKD), caregivers, and pediatric nephrology providers during outpatient clinic visits predicts antihypertensive medication adherence. METHODS: AYAs (n = 60, M age = 15.4 years, SD = 2.7, 40% female, 43% African American/Black) and caregivers (n = 60, 73% female) attended audio-recorded clinic visits with pediatric nephrologists (n = 12, 75% female). Recordings were analyzed using global affect ratings of the Roter Interactional Analysis System. Antihypertensive medication adherence was monitored electronically before and after clinic visits. A linear regression model evaluated associations between affect ratings and post-visit adherence. RESULTS: AYAs took 84% of doses (SD = 20%) pre-visit and 82% of doses (SD = 24%) post-visit. Higher AYA engagement (ß = 0.03, p = .01) and the absence of provider negative affect (ß=-0.15, p = .04) were associated with higher post-visit adherence, controlling for pre-visit adherence, AYA sex, age, and race, and clustered by provider. CONCLUSIONS: Post-visit adherence was higher when AYAs were rated as more engaged and providers as less negative. PRACTICE IMPLICATIONS: AYAs with lower engagement may benefit from further adherence assessment. Communication strategies designed to more actively engage AYAs in their care and diminish provider conveyance of negative affect during clinic visits may positively influence adherence among AYAs with CKD.

The Improving Renal Outcomes Collaborative: Blood Pressure Measurement in Transplant Recipients.

BACKGROUND AND OBJECTIVES: Hypertension is highly prevalent in pediatric kidney transplant recipients and contributes to cardiovascular death and graft loss. Improper blood pressure (BP) measurement limits the ability to control hypertension in this population. Here, we report multicenter efforts from the Improving Renal Outcomes Collaborative (IROC) to standardize and improve appropriate BP measurement in transplant patients. METHODS: Seventeen centers participated in structured quality improvement activities facilitated by IROC, including formal training in quality improvement methods. The primary outcome measure was the proportion of transplant clinic visits with appropriate BP measurement according to published guidelines. Prospective data were analyzed over a 12-week pre-intervention period and a 20-week active intervention period for each center and then aggregated as of the program-specific start date. We used control charts to quantify improvements across IROC centers. We applied thematic analysis to identify patterns and common themes of successful interventions. RESULTS: We analyzed data from 5392 clinic visits. At baseline, BP was measured and documented appropriately at 11% of visits. Center-specific interventions for improving BP measurement included educating clinic staff, assigning specific team member roles, and creating BP tracking tools and alerts. Appropriate BP measurement improved throughout the 20-week active intervention period to 78% of visits. CONCLUSIONS: We standardized appropriate BP measurement across 17 pediatric transplant centers using the infrastructure of the IROC learning health system and substantially improved the rate of appropriate measurement over 20 weeks. Accurate BP assessment will allow further interventions to reduce complications of hypertension in pediatric kidney transplant recipients.

Executive functioning, caregiver monitoring, and medication adherence over time in adolescents with chronic kidney disease.

OBJECTIVE: The purpose of this study was to evaluate associations between executive functioning and caregiver adherence monitoring with objective antihypertensive medication adherence over 24 months in adolescents with chronic kidney disease (CKD). METHODS: Adolescents (N = 97, 11-20 years old) with CKD taking antihypertensive medication and their caregivers were recruited from three pediatric nephrology clinics. At baseline, adolescents and caregivers reported on adolescents' executive functioning and caregivers reported on their adherence monitoring. Antihypertensive medication adherence was objectively assessed via electronic monitoring at baseline and every 6 months after for 24 months. Associations between executive functioning, caregiver monitoring, and longitudinal adherence were evaluated with linear mixed models. RESULTS: Up to 38% of adolescents had elevated executive functioning scores indicating more severe impairments, with rates varying by scale and reporter (adolescent vs. caregiver). Caregiver monitoring showed a significant, negative association with adherence, but adolescents' executive functioning was not significantly associated with adherence. Neither variable was associated with the rate of change in adherence over time. CONCLUSIONS: Given that adolescents' executive functioning was not associated with antihypertensive medication adherence or changes in adherence over time, adherence to daily pill-form medications may involve less cognitive effort than more complex medical regimens. Higher levels of caregiver monitoring were unexpectedly associated with lower adherence levels. This unanticipated finding may reflect increased caregiver monitoring efforts when faced with adolescents' medication nonadherence, but this finding warrants further investigation. Adolescents with CKD who are nonadherent may benefit from medication adherence-promoting strategies beyond increasing caregiver monitoring.

Evaluating provider communication in pediatric chronic kidney disease care using a global coding system.

OBJECTIVE: Among adolescents and young adults (AYAs) with chronic illness, effective provider communication is essential for patient-centered care during a sensitive developmental period. However, communication in chronic illness care for AYAs is not well studied. Our objectives were to describe the provider communication skills in pediatric chronic kidney disease (CKD) care visits; and determine if communication skills differ by AYA characteristics. METHODS: We adapted a global consultation rating system for pediatric subspecialty care using audiotaped clinic encounters of 18 pediatric nephrologists with 99 AYAs (age M(SD) = 14.9(2.6)) with CKD stages 1-5 and 96 caregivers. We hypothesized that provider communication skills would differ by AYA characteristics (age, gender, and race). RESULTS: The strongest provider skills included initiating the session and developing rapport; lowest rated skills were asking patient's perspective and checking understanding. Communication scores did not consistently differ by AYA age or race, but were rated higher with female AYAs in several domains (ps<0.05). CONCLUSIONS: Pediatric providers generally had adequate or good communication scores with AYAs, but improvement in certain skills, particularly with male AYAs, may further support patient-centered care. PRACTICE IMPLICATIONS: To achieve consistent, patient-centered communication with AYAs, an observation-based global assessment may identify areas for provider improvement.

Eplet mismatch analysis and allograft outcome across racially diverse groups in a pediatric transplant cohort: a single-center analysis.

HLA eplet mismatch load has been suggested as an improvement to HLA antigen mismatch determination for organ selection. Given that eplet mismatches are determined based on amino acid sequence difference among HLA alleles, and that the frequency of HLA alleles varies between racial groups, we investigated the correlation between eplet mismatch load and allograft outcomes in 110 pediatric kidney transplant recipients who received their first organ from a donor of the same race (SRT) versus a donor of a different race (DRT). Adjusted modified Poisson regression was used to assess the interaction between eplet mismatch load and race mismatch and its effect on outcome. Caucasians and living donor recipients had lower eplet mismatched loads against their donors compared with non-Caucasian and deceased donor recipients. Overall, for the entire population, the risk of de novo HLA-DSA development was significantly increased with higher eplet loads (p < 0.001). Compared with the SRT group, the DRT group had higher eplet loads when compared with their donor, for HLA class I but not HLA class II molecules; however, there was no significant difference in the incidence of de novo HLA-DSA between the 2 groups. The risk of rejection increased significantly for DRT compared with SRT, only when class I eplet load was ≥ 70 (p = 0.04). Together this data show that eplet mismatch load analysis is an effective tool for alloimmune risk assessment. If considered for donor selection, acceptable eplet mismatch loads determined from studies in homogenous populations may restrict transplantation across racially diverse donor and patient groups with no evidence of poor outcome. Therefore, an acceptable eplet mismatch load threshold must consider the heterogeneity of the transplant population.

A donor risk index for graft loss in pediatric living donor kidney transplantation.

Pediatric kidney transplant candidates often have multiple potential living donors (LDs); no evidence-based tool exists to compare potential LDs, or to decide between marginal LDs and deceased donor (DD) kidney transplantation (KT). We developed a pediatric living kidney donor profile index (P-LKDPI) on the same scale as the DD KDPI by using Cox regression to model the risk of all-cause graft loss as a function of living donor characteristics and DD KDPI. HLA-B mismatch (adjusted hazard ratio [aHR] per mismatch = 1.04 1.271.55 ), HLA-DR mismatch (aHR per mismatch = 1.02 1.231.49 ), ABO incompatibility (aHR = 1.20 3.268.81 ), donor systolic blood pressure (aHR per 10 mm Hg = 1.01 1.071.18 ), and donor estimated GFR (eGFR; aHR per 10 mL/min/1.73 m2 = 0.88 0.940.99 ) were associated with graft loss after LDKT. Median (interquartile range [IQR]) P-LKDPI was -25 (-56 to 12). 68% of donors had P-LKDPI <0 (less risk than any DD kidney) and 25% of donors had P-LKDPI >14 (more risk than median DD kidney among pediatric KT recipients during the study period). Strata of LDKT recipients of kidneys with higher P-LKDPI had a higher cumulative incidence of graft loss (39% at 10 years for P-LDKPI ≥20, 28% for 20> P-LKDPI ≥-20, 23% for -20 > P-LKDPI ≥-60, 19% for P-LKDPI <-60 [log rank P < .001]). The P-LKDPI can aid in organ selection for pediatric KT recipients by allowing comparison of potential LD and DD kidneys.

Patient Health Beliefs and Characteristics Predict Longitudinal Antihypertensive Medication Adherence in Adolescents With CKD.

Objective: To investigate longitudinal associations of health beliefs, which included self-efficacy, outcome expectancies, and perceived barriers, and demographic risk factors (i.e., age, gender, race, and family income) with antihypertensive medication adherence in adolescents with chronic kidney disease (CKD) over 24 months. Method: The sample included 114 adolescents (M age = 15.03 years, SD = 2.44) diagnosed with CKD. Adolescents reported their self-efficacy for taking medications, medication outcome expectancies, and barriers to adherence at baseline and 12 and 24 months after baseline. Antihypertensive medication adherence was assessed via electronic monitoring for 2 weeks at baseline and 6, 12, 18, and 24 months after baseline. Results: Adherence increased and then decreased over the 2-year study period (inverted U-shape). Self-efficacy, outcome expectancies, and barriers did not change over time. Older adolescent age, female gender, African American race, <$50,000 annual family income, and public health insurance were associated with lower adherence. However, family income was the primary demographic risk factor that predicted adherence over time (≥$50,000 annual family income was longitudinally associated with higher adherence). Higher self-efficacy and more positive and less negative outcome expectancies across time were also associated with higher antihypertensive medication adherence across time. Conclusions: Clinical interventions should be developed to target medication self-efficacy and outcome expectancies to improve long-term antihypertensive medication adherence in adolescents with CKD. Family income may be considered when conceptualizing contextual factors that likely contribute to adolescents' consistent challenges with medication adherence over time.

Does a multimethod approach improve identification of medication nonadherence in adolescents with chronic kidney disease?

BACKGROUND: Medical provider assessment of nonadherence is known to be inaccurate. Researchers have suggested using a multimethod assessment approach; however, no study has demonstrated how to integrate different measures to improve accuracy. This study aimed to determine if using additional measures improves the accurate identification of nonadherence beyond provider assessment alone. METHODS: Eighty-seven adolescents and young adults (AYAs), age 11-19 years, with chronic kidney disease (CKD) [stage 1-5/end-stage renal disease (ESRD)] and prescribed antihypertensive medication, their caregivers, and 17 medical providers participated in the multisite study. Five adherence measures were obtained: provider report, AYA report, caregiver report, electronic medication monitoring (MEMS), and pharmacy refill data [medication possession ratio (MPR)]. Concordance was calculated using kappa statistic. Sensitivity, specificity, positive predictive power, and negative predictive power were calculated using MEMS as the criterion for measuring adherence. RESULTS: There was poor to fair concordance (kappas = 0.12-0.54), with 35-61% of AYAs classified as nonadherent depending on the measure. While both providers and MEMS classified 35% of the AYAs as nonadherent, sensitivity (0.57) and specificity (0.77) demonstrated poor agreement between the two measures on identifying which AYAs were nonadherent. Combining provider report of nonadherence and MPR < 75% resulted in the highest sensitivity for identifying nonadherence (0.90) and negative predictive power (0.88). CONCLUSIONS: Nonadherence is prevalent in AYAs with CKD. Providers inaccurately identify nonadherence, leading to missed opportunities to intervene. Our study demonstrates the benefit to utilizing a multimethod approach to identify nonadherence in patients with chronic disease, an essential first step to reduce nonadherence.

Effects of obesity and race on left ventricular geometry in hypertensive children.

BACKGROUND: Like left ventricular hypertrophy (LVH), abnormal left ventricular (LV) geometry increases cardiovascular risk, but little data utilizing age and sex-specific norms are currently available on LV geometry in hypertensive children. METHODS: This was a cross-sectional study of 141 hypertensive children aimed at determining the prevalence of LVH and abnormal LV geometry in the patient population and whether clinical characteristics associated with these findings differ by race. LVH was defined as an LV mass index of ≥95th percentile or cardiologist diagnosis. Abnormal geometry was defined as the presence of LVH or a relative wall thickness of >0.41. RESULTS: The prevalence of LVH was 35 % overall. According to race, LVH prevalence was 49 % among African-Americans (AA) versus 30 % among non-AA (p < 0.05). Overweight/obesity was also highly prevalent among AA compared to non-AA (87 vs. 71 %, respectively; p = 0.03). After multivariable adjustment, the body mass index (BMI) z-score and 95 % diastolic blood pressure (BP) index were the sole independent predictors of LVH. Of the 141 hypertensive children, 40 % had abnormal LV geometry; 63 % among AA vs. 32 % among non-AA (p = 0.001). Multivariable analyses revealed a 3.8-fold increased odds of abnormal geometry among AA (p = 0.002). CONCLUSIONS: While LVH, abnormal geometry and overweight/obesity are more prevalent among AA hypertensive children, after multivariable adjustment, BMI and race were independently associated with LVH and abnormal geometry, respectively. This result suggests that both race and obesity have important roles in the development of end-organ damage among children with primary hypertension.
