Statistical literacy is poor in most orthopaedic trauma patients. Lower education and older age predict lower numeracy skills, impacting informed consent for surgical options.
Area of Science:
- Orthopaedic Surgery
- Patient Education
- Health Literacy
Background:
- Statistical literacy is crucial for understanding medical information.
- Orthopaedic trauma patients often face complex treatment decisions.
Purpose of the Study:
- To assess statistical literacy in orthopaedic trauma patients.
- To identify demographic factors associated with poor numeracy skills.
Main Methods:
- Prospective observational study at a Level 1 trauma center.
- 198 orthopaedic trauma patients were evaluated.
- Berlin Numeracy Test (BNT) and General Health Numeracy Test-6 (GHNT-6) were administered.
Main Results:
- 67% of patients scored in the lowest quartile of numeracy on the BNT.
- Older age and lower education levels predicted poorer BNT performance.
- Mean GHNT-6 score was 36%.
Conclusions:
- Poor statistical literacy is prevalent among orthopaedic trauma patients.
- Age and education are key predictors of numeracy.
- These factors must be considered during patient consultations regarding risks and treatment options.
