What problem does it solve?

This Skill enables clinicians and data scientists to compute the Hospital Frailty Risk Score (HFRS) from ICD diagnosis codes, enabling frailty assessment and risk stratification using current and prior admissions.

Core Features & Use Cases

• ICD-based frailty scoring: derives HFRS from ICD-10 and ICD-9 mappings, enabling compatibility with datasets like MIMIC-IV.
• Two-year history integration: incorporates the index admission plus emergency admissions in the preceding two years to reflect frailty status.
• Output and reuse: returns a numeric score, risk category, and the list of contributing codes, with Python and SQL examples for reproducible analysis.

Quick Start

Provide a list of ICD-coded diagnoses for a patient and run the calculation to obtain the HFRS score.
