Participant Flow
This was a stepped-wedge, cluster-randomized trial with 18 clinical sites assigned to 3 randomized sequences (6 sites per seq.). Each sequence progressed through Baseline (usual care), Implementation and Sustainability phases at different calendar times according to the prespecified roll-out. Participants reported by the phase active at their site at time of surgery. Learning Collaborative personnel were not research participants and do not contribute to Participant Flow, Outcome Measures or AEs
Sites (clusters) were randomized into 3 sequences (6 sites/sequence) and crossed from Baseline to Implementation to Sustainability per the prespecified roll-out. Participants were enrolled continuously according to surgery dates.

Participant milestones
| Measure |
Sequence 1 (Early Implementation Sites)
Clinical sites (clusters) were randomized by the data coordinating team into three sequences for the stepped-wedge design, stratified to include two lower-volume and four higher-volume sites per sequence. Sites in this sequence initiated the ENRICH-US protocol in the first step. Sites contributed data according to the study schedule: Baseline (pre-implementation) 6 months, Implementation 12 months, and Sustainability 24 months. During baseline, sites provided standard care. During implementation and sustainability, sites implemented the 21-element ENRICH-US protocol supported by a structured implementation toolkit, learning collaborative curriculum, ERP adherence data feedback, and implementation report cards.
|
Sequence 2 (Mid Implementation Sites)
Clinical sites (clusters) were randomized by the data coordinating team into three sequences for the stepped-wedge design, stratified to include two lower-volume and four higher-volume sites per sequence. Sites in this sequence initiated the ENRICH-US protocol in the second step. Sites contributed data according to the study schedule: Baseline (pre-implementation) 12 months, Implementation 12 months, and Sustainability 18 months. During baseline, sites provided standard care. During implementation and sustainability, sites implemented the 21-element ENRICH-US protocol supported by a structured implementation toolkit, learning collaborative curriculum, ERP adherence data feedback, and implementation report cards.
|
Sequence 3 (Late Implementation Sites)
Clinical sites (clusters) were randomized by the data coordinating team into three sequences for the stepped-wedge design, stratified to include two lower-volume and four higher-volume sites per sequence. Sites in this sequence initiated the ENRICH-US protocol in the third step. Sites contributed data according to the study schedule: Baseline (pre-implementation) 18 months, Implementation 12 months, and Sustainability 12 months. During baseline, sites provided standard care. During implementation and sustainability, sites implemented the 21-element ENRICH-US protocol supported by a structured implementation toolkit, learning collaborative curriculum, ERP adherence data feedback, and implementation report cards.

Patient-Reported Outcomes Measurement Information System (PROMIS) Pediatric Global Health T-score before surgery. The PROMIS Pediatric Global Health Scale (PGH-7) is a validated, standardized patient-reported outcome measure assessing overall physical, mental, and social health in children and adolescents. Scores are reported as T-scores standardized to the U.S. pediatric population, with a mean of 50 and standard deviation of 10. Possible scores typically range from approximately 20 to 80. Higher T-scores indicate better global health. The PROMIS Pediatric Global Health T-score was assessed preoperatively within 30 days prior to surgery and summarized by study phase.

The PROMIS Pediatric Pain Interference Scale is a validated patient-reported outcome measure assessing the extent to which pain interferes with physical, emotional, and social functioning in children and adolescents. Scores are reported as standardized T-scores with a mean of 50 and standard deviation of 10, with a typical range of approximately 30 to 80. Higher T-scores indicate greater pain interference (worse outcome). Pain interference T-scores were assessed preoperatively within 30 days prior to surgery and summarized by study phase.

All adverse event data collected during the study are reported. No deaths or serious adverse events occurred. Postoperative complications were collected prospectively from electronic health records by trained site coordinators using MedDRA terminology. All complications collected are reported; only those meeting the ≥5% frequency threshold are displayed in the "Other (Not Including Serious) Adverse Events" table, per ClinicalTrials.gov requirements.
