aDenominator excludes trauma, immunocompromised, and cancer patients.
b Rates 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.
cFor 1994, rate biased in unknown direction because procedure codes 52.85-52.86 used to exclude discharges from the numerator and denominator became effective after 1994 and before 1997. The effect should be small because these codes for transplantations are unlikely to be in low-mortality DRGs.
