Project Overview
Creating a taxonomy and general severity of illness and injury system for EMSC is a research priority, yet no such system exists. Standard systems must be available to assess quality of emergency care across settings, patient populations and practitioners.
The goals of this project are to (1) create taxonomy of disease for EMSC, titled the Diagnosis Grouping System (DGS), which will group ICD-9 diagnoses into clinically sensible categories for research and reporting; (2) create a Severity of Illness Classification System (SCS) by stratifying ICD-9 diagnoses in each DGS Group into severity categories and examine the relationship between severity and resource use; and (3) evaluate the DGS and SCS by applying it to external data sets to ensure the system is applicable to data sets routinely used by EMSC researchers, clinicians, policy makers, and administrators.
