A hospital compares pressure-injury rates between a general medical ward and an intensive care unit. Which method improves the fairness of this comparison?
Correct answer: A. Adjust the comparison for differences in patient risk and severity
- A. Adjust the comparison for differences in patient risk and severity
- B. Compare only the total number of pressure injuries in each ward
- C. Exclude pressure injuries that were documented after admission
- D. Use the ward with fewer patients as the performance standard
Explanation
Patients in intensive care often have greater immobility and illness severity, so crude rates may be misleading. Risk adjustment or stratification helps determine whether differences reflect care quality rather than patient characteristics.
