  1. 1 ID: Anonymous hospital identifier;
  2. 2 LB_B: Lower bound of the Bonferroni confidence interval;
  3. 3 LB_95: Lower bound of the 95% confidence interval;
  4. 4 D: departure of a hospital's CSR compared with the national CSR/national trend;
  5. 5 UB_95: Upper bound of the 95% confidence interval;
  6. 6 UB_B: Upper bound of the Bonferroni confidence interval;
  7. 7 CI_95: +: a 95% CI suggests a significantly higher hospital's rate/trend compared with the national rate/trend,
  8. -: a 95% CI suggests a significantly lower hospital's rate/trend compared with the national rate/trend,
  9. NS: a 95% CI does not suggest a significant departure of the hospital's rate/trend compared with the national rate/trend.
  10. 8 CI_B: +: a Bonferroni-corrected CI strongly suggests a significantly higher hospital's rate/trend compared with the national rate/trend,
  11. -: a Bonferroni-corrected CI strongly suggests a significantly lower hospital's rate/trend compared with the national rate/trend,
  12. NS: a Bonferroni-corrected CI does not suggest a significant departure of the hospital's rate/trend compared with the national rate/trend.
  13. 9 P value: Probability of observing departures such as these assuming the null hypothesis of no departure is true.
  14. 10IP: Interpretation: EA: External audit and general measures recommended; GM: General measures recommended.
