The Hospital Frailty Risk Score (HFRS) is an administrative-data frailty measure derived from diagnosis-code patterns in hospitalized older adults. It stratifies patients into low, intermediate, and high frailty-associated hospital risk categories. HFRS is primarily used at system/population level for risk adjustment, service planning, and identifying patients likely to require more complex inpatient care.
Formula: HFRS category thresholds: low <5, intermediate 5-15, high >15.
Higher HFRS values indicate greater frailty-associated hospital risk and may support proactive multidisciplinary inpatient care planning.
Use in inpatient and quality-improvement contexts where diagnosis-code-derived frailty risk stratification is needed for service design or risk adjustment.
HFRS depends on coding completeness and was not designed as a standalone bedside frailty diagnosis tool for individual treatment decisions.
For related assessments, see Clinical Frailty Scale, ISAR Score and VES-13.
