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.

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 ( = 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.

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.

Association of a Simulated Institutional Gender Equity Initiative With Gender-Based Disparities in Medical School Faculty Salaries and Promotions.

Importance: Despite progress in narrowing gender-based salary gaps, notable disparities persist in the scientific community. The significance of pay difference may be underestimated, with little data evaluating its effect on lifetime wealth after accounting for factors like time to promotion and savings.

Objectives: To characterize gender disparities in salary and assess the outcomes associated with a gender equity initiative (GEI).

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.

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.

Association of higher erythropoiesis stimulating agent dose and mortality in children on dialysis.

Background: Higher doses of erythropoiesis-stimulating agents (ESA) have been associated with an increased risk of adverse outcomes in adults with chronic kidney disease (CKD) and end-stage kidney disease (ESRD), but to our knowledge no trials have been performed in children. We examined the association between ESA dose and all-cause mortality in a prevalent pediatric dialysis population.

Methods: Retrospective cohort study utilizing national data on all prevalent dialysis patients aged <18 years from the Centers for Medicare and Medicaid Services' 2005 ESRD Clinical Performance Measures (CPM) project, linked to 18-month mortality records from the United States Renal Data System.

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.

Comparative clinical outcomes between pediatric and young adult dialysis patients.

Published data on the comparative achievement of The Kidney Disease Dialysis Outcome Quality Initiative (KDOQI) recommended clinical performance targets between children and young adults on dialysis are scarce. To characterize the achievement of KDOQI targets among children (<18 years) and young adults (18-24 years) with prevalent end stage renal disease (ESRD), we performed a cross-sectional analysis of data collected by the Mid-Atlantic Renal Coalition, in conjunction with the 2007 and 2008 ESRD Clinical Performance Measures Projects. Data on all enrolled pediatric dialysis patients, categorized into three age groups (0-8, 9-12, 13-17 years), and on a random sample of 5% of patients ≥ 18 years in ESRD Network 5 were examined for two study periods: hemodialysis (HD) data were collected from October to December 2006 and from October to December 2007 and peritoneal dialysis (PD) data were collected from October 2006 to March 2007 and from October 2007 to March 2008.

Predictors and consequences of higher estimated glomerular filtration rate at dialysis initiation.

There have been no studies in pediatric dialysis patients to evaluate the impact of higher estimated glomerular filtration rate (eGFR) at dialysis initiation on clinical outcomes. Baseline clinical and demographic information was collected for children aged 1-18 years undergoing incident dialysis from 1995-2002 within the United States Renal Data System. Baseline eGFRs calculated by the Schwartz formula were categorized as high (>15 ml/min/1.

Secondary hyperparathyroidism and anemia in children treated by hemodialysis.

Background: Many patients treated using hemodialysis remain anemic despite exogenous erythropoietin therapy, suggesting that the anemia experienced by these patients is multifactorial in cause. Iron deficiency, infection, inflammation, and malnutrition have been implicated in this process. Additionally, secondary hyperparathyroidism has been associated with anemia in adults, but few data exist about this topic in children.

Persistent low albumin and temporary vascular access in pediatric patients with SLE on hemodialysis.

Pediatric patients with systemic lupus erythematosus (SLE) often present with significant kidney disease. In a previous cross-sectional analysis, we showed that pediatric patients with ESRD secondary to SLE have lower serum albumin levels and less permanent vascular access for hemodialysis (HD) compared to pediatric patients on HD secondary to other causes. The goal of this longitudinal study was to determine if there was an improvement in these targets over time.

Patterns of use of vascular catheters for hemodialysis in children in the United States.

Background: Arteriovenous fistulas (AVFs) and grafts (AVGs) have been associated with improved clinical outcomes in children and adults with end-stage renal disease (ESRD) on maintenance hemodialysis (HD) therapy, but use of vascular catheters is high. Identifying the reasons for the high prevalence of vascular catheters in children on HD therapy is necessary to assess whether targeted interventions may increase the prevalence of AVFs/AVGs.

Study Design: Retrospective cohort study.

A randomized controlled trial of the effectiveness of osteopathy-based manual physical therapy in treating pediatric dysfunctional voiding.

Objective: Pediatric dysfunctional voiding (DV) presents physical and emotional challenges as well as risk of progression to renal disease. Manual physical therapy and osteopathic treatment have been successfully used to treat DV in adult women; a pediatric trial of manual physical therapy based on an osteopathic approach (MPT-OA) has not been reported. The aim of this study was to determine whether MPT-OA added to standard treatment (ST) improves DV more effectively than ST alone.

Disparate outcomes in pediatric peritoneal dialysis patients by gender/race in the End-Stage Renal Disease Clinical Performance Measures project.

Associations between achievement of adult Kidney Disease Outcomes Quality Initiative (KDOQI) targets for hemoglobin, adequacy and albumin, and race and gender were determined for pediatric peritoneal dialysis patients from the End-Stage Renal Disease (ESRD) Clinical Performance Measures (CPM) project for the period October 2004-March 2005. Fifty-six percent (427/761) of patients were male. Sixty-six percent (500/761) of patients were White.

Reduced albumin levels and utilization of arteriovenous access in pediatric patients with systemic lupus erythematosus (SLE).

Systemic lupus erythematosus (SLE) is an autoimmune disease that affects between five and ten thousand children in the USA. Kidney disease may progress to end-stage renal disease (ESRD) and subsequent need for dialysis therapy in a significant number of children with SLE. We performed a cross-sectional analysis comparing achievement of National Kidney Foundation/Kidney Disease Outcomes Quality Initiative clinical targets in pediatric patients with SLE maintained on hemodialysis (HD) to pediatric patients with other causes of ESRD.

Ethnic disparity in outcomes for pediatric peritoneal dialysis patients in the ESRD Clinical Performance Measures Project.

Ethnicity information was collected for all pediatric peritoneal dialysis patients from the End-Stage Renal Disease (ESRD) Clinical Performance Measures (CPM) Project for the period October 2004 through March 2005. Associations between intermediate outcomes and Hispanic ethnicity were determined. Thirty percent (207/696) of patients in the final cohort were Hispanic, 24% (165/696) non-Hispanic black, and 46% (324/696) non-Hispanic white.

Clinical course associated with vascular access type in a national cohort of adolescents who receive hemodialysis: findings from the Clinical Performance Measures and US Renal Data System projects.

Limited research has described clinical outcomes that are associated with the type of vascular access in pediatric patients who receive maintenance hemodialysis. This retrospective cohort study examined prevalent pediatric patients who were aged 12 to <18 yr and identified in the 2000 ESRD Clinical Performance Measures Project as receiving in-center hemodialysis. Vascular access type as of December 31, 1999, was identified.

Outcomes for adolescent Hispanic hemodialysis patients: findings from the ESRD Clinical Performance Measures Project.

Background: There is limited information regarding outcomes of dialytic care for Hispanic adolescent hemodialysis patients.

Methods: Ethnicity information was collected for all adolescent in-center hemodialysis patients for the Centers for Medicare & Medicaid Services 2000 End-Stage Renal Disease (ESRD) Clinical Performance Measures Project. Associations between intermediate outcomes and Hispanic ethnicity were determined.

Impact of specialization of primary nephrologist on the care of pediatric hemodialysis patients.

Background: Children with end-stage renal disease (ESRD) receiving hemodialysis may have their care overseen primarily by a pediatric nephrologist or internal medicine (IM) nephrologist.

Methods: To examine specific clinical outcomes by nephrologist specialization, a cross-sectional analysis of demographic and clinical data collected in the 2002 ESRD Clinical Performance Measures Project was performed.

Results: Of 653 pediatric patients meeting inclusion criteria, 27% were cared for by IM nephrologists, and 73%, by pediatric nephrologists.

Growth in adolescent hemodialysis patients: data from the Centers for Medicare & Medicaid Services ESRD Clinical Performance Measures Project.

The Centers for Medicare & Medicaid Services' (CMS) end-stage renal disease (ESRD) Clinical Performance Measures (CPM) Project has collected data on all adolescent hemodialysis patients since 2000. Thus, by 2002 data were available on all adolescents on hemodialysis in the USA for 3 consecutive years. Possible associations between clinical parameters and linear growth in this cohort were evaluated.

Incidence of atherosclerosis by race in the dialysis morbidity and mortality study: a sample of the US ESRD population.

White individuals who are on dialysis experience much higher overall and cardiovascular mortality rates than black individuals despite a more favorable risk factor profile, but the incidence of nonfatal cardiovascular disease (CVD) to this racial disparity has not been well studied. A longitudinal study of 16,103 people who had ESRD and were enrolled in the United Renal Data System from 1993 to 1996 was conducted. The incidence of new and recurrent atherosclerotic CVD (ASCVD) events was determined using Medicare claims for hospitalizations and mortality among blacks and whites, stratified by ASCVD at baseline.

Assessing health status and health care utilization in adolescents with chronic kidney disease.

Few validated health status measures have been assessed in children with chronic kidney disease (CKD). The objective was to assess the validity of a generic health status measure, the Child Health and Illness Profile-Adolescent Edition (CHIP-AE), in adolescents with CKD. A case-control study was performed (1) to assess scores on the CHIP-AE in adolescents with CKD compared with two control groups of age-, socioeconomic-, and gender-matched peers and (2) to compare health of patients who had chronic renal insufficiency (CRI), were on dialysis, and were posttransplantation.

Anemia in pediatric dialysis patients in end-stage renal disease network 5.

To identify demographic and clinical characteristics associated with failure to achieve hemoglobin levels >/=11 g/dl in prevalent pediatric end-stage renal disease (ESRD) patients, a cross-sectional analysis of patient clinical data collected by the Mid-Atlantic Renal Coalition in conjunction with the 2000 and 2001 ESRD Clinical Performance Measures Projects was performed. Ninety-nine patients (mean age 12.6 years, SD 5.

Drug dosing during intermittent hemodialysis and continuous renal replacement therapy : special considerations in pediatric patients.

Chronic renal failure is, fortunately, an unusual occurrence in children; however, many children with various underlying illnesses develop acute renal failure, and transiently require renal replacement therapy - peritoneal dialysis, intermittent hemodialysis (IHD), or continuous renal replacement therapy (CRRT). As children with acute and chronic renal failure often have multiple comorbid conditions requiring drug therapy, generalists, intensivists, nephrologists, and pharmacists need to be aware of the issues surrounding the management of drug therapy in pediatric patients undergoing renal replacement therapy. This article summarizes the pharmacokinetics and dosing of many drugs commonly prescribed for pediatric patients, and focuses on the management of drug therapy in pediatric patients undergoing IHD and CRRT in the intensive care unit setting.
