Patient-centered outcomes in pediatric continuous kidney replacement therapy: new morbidity and worsened functional status in survivors.

BACKGROUND: Ongoing measures to improve pediatric continuous kidney replacement therapy (CKRT) have lowered mortality rates, shifting the focus to survivor functional status. While septic acute kidney injury generates new morbidity in pediatric critically ill patients, acquired morbidities and functional status of CKRT population are unknown. We predicted that CKRT survivors are at risk for new morbidity and would have worse functional status at PICU discharge compared to baseline, and aimed to describe associated factors. METHODS: Retrospective cohort study over 24 months of CKRT patients surviving to PICU discharge in a quaternary children's hospital. Functional outcome was determined by Functional Status Scale (FSS). RESULTS: FSS scores were higher at PICU and hospital discharge compared to baseline. Of 45 CKRT survivors, 31 (69%) had worse FSS score at PICU discharge and 51% had new morbidity (≥3 increase in FSS); majority qualified as moderate to severe disability (FSS ≥10). Four patients (9%) had new tracheostomy, 3 (7%) were ventilator dependent, and 10 (22%) were dialysis dependent. Most (23/45, 51%) required outpatient rehabilitation. Cumulative days on sedation, controlled for illness severity, were independently associated with worse FSS at PICU discharge (aOR 25.18 (3.73, 169.92)). In adjusted analyses, duration of sedation was associated with new morbidity, while neurologic comorbidity, percent fluid overload at CKRT start, and nonrenal comorbidity were associated with moderate to severe disability at PICU discharge when controlled for baseline FSS. CONCLUSIONS: CKRT survivors, with new morbidity and worse functional outcomes at PICU discharge, are a newly described vulnerable population requiring targeted follow-up. Deliberate decrease of sedation exposure in patients with decreased clearance due to organ dysfunction needs to be studied as a modifiable risk factor.

Quality Improvement Bedside Rounding Audits Enhance Protein Provision for Pediatric Patients Receiving Continuous Renal Replacement Therapy.

OBJECTIVES: Describe quality improvement process improvements in protein delivery of continuous renal replacement therapy initiation. DESIGN: Prospective study. SETTING: PICU and cardiovascular ICU within a quaternary care children's hospital. PATIENTS: PICU and cardiovascular ICU patients receiving continuous renal replacement therapy for greater than 48 hours. Inborn errors of metabolism were excluded. INTERVENTIONS: Plan-Do-Study-Act cycles were initiated. Cycle 1 developed interdisciplinary quality improvement group continuously monitoring nutrition care with thrice weekly bedside safety rounds and protein prescriptions within nephrologist's notes. Cycle 2 included education to intensivists. Cycle 3 initiated monthly quality improvement meetings reviewing nutritional care goals. MEASUREMENTS AND MAIN RESULTS: Primary outcome was percentage of time patients met protein goals in the first 5 days of continuous renal replacement therapy. Secondary outcome was percentage of time patients met protein goals for duration of continuous renal replacement therapy. Cohort (n = 55) mean age was 8.1 years (SD ± 6.8), 62% male, and 31% malnutrition at baseline. Percent of time meeting protein goals by day 5 was 22%, 33%, and 71% and percent of time meeting protein goals throughout was 35%, 39%, and 75% of groups 1, 2, and 3, respectively. Significant improvement occurred after Plan-Do-Study-Act 3 (group 2 vs group 3; p < 0.01) for primary and secondary outcomes. CONCLUSIONS: Implementation of an interprofessional quality improvement team significantly decreased number of continuous renal replacement therapy days with unmet protein goals and improved protein delivery.

Consensus-Based Recommendations on Priority Activities to Address Acute Kidney Injury in Children: A Modified Delphi Consensus Statement.

Importance: Increasing evidence indicates that acute kidney injury (AKI) occurs frequently in children and young adults and is associated with poor short-term and long-term outcomes. Guidance is required to focus efforts related to expansion of pediatric AKI knowledge. Objective: To develop expert-driven pediatric specific recommendations on needed AKI research, education, practice, and advocacy. Evidence Review: At the 26th Acute Disease Quality Initiative meeting conducted in November 2021 by 47 multiprofessional international experts in general pediatrics, nephrology, and critical care, the panel focused on 6 areas: (1) epidemiology; (2) diagnostics; (3) fluid overload; (4) kidney support therapies; (5) biology, pharmacology, and nutrition; and (6) education and advocacy. An objective scientific review and distillation of literature through September 2021 was performed of (1) epidemiology, (2) risk assessment and diagnosis, (3) fluid assessment, (4) kidney support and extracorporeal therapies, (5) pathobiology, nutrition, and pharmacology, and (6) education and advocacy. Using an established modified Delphi process based on existing data, workgroups derived consensus statements with recommendations. Findings: The meeting developed 12 consensus statements and 29 research recommendations. Principal suggestions were to address gaps of knowledge by including data from varying socioeconomic groups, broadening definition of AKI phenotypes, adjudicating fluid balance by disease severity, integrating biopathology of child growth and development, and partnering with families and communities in AKI advocacy. Conclusions and Relevance: Existing evidence across observational study supports further efforts to increase knowledge related to AKI in childhood. Significant gaps of knowledge may be addressed by focused efforts.
