Interpretation of Results
Observed to Expected (O/E) Ratio
- Hospital’s outcomes compared to the other ACS-NSQIP hospitals,
adjusted for inter-hospital differences in patients’ characteristics, comorbidities, and preoperative laboratory values
LOW OUTLIER: If the upper bound of the O/E confidence interval is <1.0, the hospital’s outcomes are statistically better than expected. Thus, the hospital’s outcomes are “Exemplary.” ACS NSQIP Hospital ID Number HIGH OUTLIER: If the lower bound of the O/E ratio is >1.0, the hospital’s outcomes are statistically worse than
- expected. Thus, the hospital’s outcomes “Need
Improvement.” AS EXPECTED
