Abstract
BACKGROUND: The pediatric intensive care unit (PICU) is an environment where seriously ill children receive complex care, delivered mostly by specialty-trained nurses (registered nurses [RNs]) who must perform multiple high-level tasks. With stressors on healthcare systems at an all-time high, design that optimizes RN workflow has taken on a renewed imperative. OBJECTIVES: To employ a multimodal approach (1) to identify environmental factors in the PICU patient room that contribute to caregiver workflow inefficiencies, (2) to optimize safety by identifying high-touch surfaces that cause hospital-acquired infections, (3) to develop human-centered design recommendations. METHODS: This mixed-method case study was conducted in a 23-bed urban hospital PICU. The activities, movements, and workflows of 13 RNs were recorded using spatial movement mapping, behavioral mapping, and clinical activity mapping. Frequency of RN contact with surfaces was documented to assess relative infection transmission risk. Face-to-face interviews were conducted with RNs to elicit their views on care delivery and their physical work environment. RESULTS: Direct patient care occupied 50% of RNs' time. Of the direct patient care workflow activities recorded, 26% were to prepare for care around the bedside, while 27% were for random travel between clean and soiled areas. The surfaces most frequently touched were (1) patient bedrails, (2) intravenous pumps and poles, (3) tubing and medical equipment, and (4) vital sign monitors. CONCLUSION: Value-added tasks account for only about 20% of nurses' work. Combining technology and strategic interior design to streamline workflow and enhance infection prevention optimizes efficiency and empowers frontline providers to maximize their time at the bedside performing value-added tasks.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
