Abstract

OBJECTIVES:

To investigate the efficacy of a novel geriatric trauma risk assessment tool [Score for Trauma Triage in the Geriatric and Middle-Aged (STTGMA)] designed to predict inpatient mortality to risk-stratify measures of hospital quality and cost of care in middle-aged and geriatric orthopaedic trauma patients.

DESIGN:

Prospective cohort study.

SETTING:

Academic medical center.

PATIENTS:

One thousand five hundred ninety-two patients 55 years of age and older who were evaluated by orthopaedic surgery in the emergency department between October 1, 2014, and September 30, 2016.

INTERVENTION:

Calculation of the inpatient mortality risk score (STTGMA) using each patient's demographics, injury severity, and functional status. Patients were stratified into minimal-, low-, moderate-, and high-risk cohort groups based on risk of <0.9%, 0.9%-1.9%, 1.9%-5%, and >5%.

MAIN OUTCOME MEASUREMENTS:

Length of stay, complications, disposition, readmission, and cost.

RESULTS:

One thousand two hundred seventy-eight patients (80.3%) sustained low-energy injuries and 314 patients (19.7%) sustained high-energy injuries. The average age was 73.8 ± 11.8 years. The mean length of hospital stay was 5.2 days with a significant difference between the STTGMA risk groups. This risk stratification between groups was also seen in complication rate, need for Intensive Care Unit/Step Down Unit care, percentage of patients discharged, and readmission within 30-days. The mean total cost of admission for the minimal-risk group was less than one-third that of the high-risk cohort.

CONCLUSIONS:

The STTGMA tool is able to risk-stratify hospital quality outcome measures and cost. Thus, it is a valuable clinical tool for health care providers in identifying high-risk patients in efforts to continue to provide high-quality resource conscious care to orthopaedic trauma patients.

LEVEL OF EVIDENCE:

Prognostic Level II. See Instructions for Authors for a complete description of levels of evidence.
