a Postoperative hemorrhage or hematoma is not verifiable as following surgery because information on day of procedure is not available for all discharges. Numerator excludes admissions specifically for such problems, such as cases from earlier admissions, from other hospitals, or from other settings. Denominator excludes obstetrical admissions.

bRates are adjusted by age, gender, age-gender interactions, comorbidities, and DRG clusters. When reporting is by age, the adjustment is by gender, comorbidities, and DRG clusters; when reporting is by gender, the adjustment is by age, comorbidities, and DRG clusters.

* Information is unavailable for year 1994; all required diagnosis codes (998.11, 998.12) used to include discharges became effective after 1994 and before 1997.
