Abstract	Predictive scores are increasingly incorporated into bedside care to support early recognition of clinical deterioration, prioritization of nursing surveillance, escalation of care, and allocation of clinical attention. Early warning scores offer a structured method for combining physiological observations into an interpretable risk signal, while newer electronic and algorithmic systems can integrate substantially larger clinical datasets. Their apparent objectivity, however, creates important ethical questions concerning false reassurance, excessive alerts, subgroup bias, incomplete observations, automation dependence, transparency, accountability, and the continuing role of professional nursing judgment. This simulation-based study develops an ethical framework for bedside use of predictive scores in adult inpatient nursing. A hypothetical dataset of 1,000 patient observation episodes was constructed to examine how changing escalation thresholds could alter sensitivity for clinical deterioration and the proportion of encounters generating alerts. Because no real patient records were supplied, all numerical results are synthetic and intended exclusively for methodological demonstration. Under the simulated model, a low escalation threshold produced 95% sensitivity but generated alerts in 49% of encounters, whereas a substantially higher threshold reduced alert burden to 11% but lowered sensitivity to 51%. The findings illustrate an ethical trade-off rather than an optimal clinical threshold. Research available through 2020 demonstrates that early warning scores can discriminate risk but that their methodological quality and real-world implementation performance vary. A 2020 systematic review found important methodological weaknesses across many early warning score studies, while implementation research has shown that frequent low-value alerts can be ignored by frontline staff. Evidence from nursing literature also indicates that nurses use observation, experience, intuition, and pattern recognition in identifying deterioration, supporting a model in which predictive scores augment rather than replace bedside assessment. The study concludes that ethical deployment requires local validation, transparent escalation protocols, subgroup performance auditing, preservation of nurse-initiated escalation, documentation of overrides, and continuous monitoring for patient-safety consequences.
