Projected Cost-beneficial Impact of the Selective Cytopheretic Device in Pediatric Acute Kidney Injury Requiring Kidney Replacement Therapy
Bibliographic record
Abstract
Abstract Rationale & Objective The Selective Cytopheretic Device for Pediatrics (SCD-PED) is a cell-directed extracorporeal therapy approved by US FDA for pediatric patients with acute kidney injury (AKI) due to sepsis or a septic condition, requiring antibiotics and continuous renal replacement therapy (CRRT). This study aimed to estimate hospitalization costs and outcomes of SCD-PED therapy by leveraging the Kids’ Inpatient Database (KID) and SCD-PED studies. Study Design Publicly available hospitalization cost data were combined with clinical metrics from prior SCD-PED studies to assess the impact of SCD-PED on inpatient hospital costs among pediatric patients receiving CRRT. Setting & Population The SCD-PED was evaluated in two multicenter pediatric studies, involving 16 and 6 patients, respectively. Pediatric patients with AKI and multi-organ dysfunction receiving CRRT as part of standard care were included. The KID subset comprised hospitalizations with CRRT, a length of stay (LOS) up to 60 days, mortality and severity level 4, an AKI diagnosis, and total parenteral nutrition (TPN) procedures. Interventions Patients received SCD-PED therapy for up to 7 or 10 days or until CRRT termination. Outcomes Outcomes analyzed included hospital LOS, mortality, vasopressor use, mechanical ventilation, sepsis diagnosis, number of SCD-PED devices used, and hospitalization cost estimates. Model, Perspective, & Timeframe A regression-based economic cost model compared costs between SCD-PED therapy and theoretical controls, adjusted to 2024 US dollars. Results Modeled hospitalization costs were $457,092 in the KID cohort and $389,451 in the ppCRRT cohort. Median hospital LOS was lower in the SCD-PED group (28 days vs. 31 days), resulting in lower estimated costs ($320,304) and an estimated savings of $69,146 per hospitalization. Limitations Small sample sizes and single-arm design with no prospective control arm. Reported costs are estimates based on models. Conclusions The SCD-PED shows potential for survival benefit and cost-benefit in critically ill children with AKI requiring CRRT, including those with sepsis.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
