a Denominator excludes paralysis patients, patients admitted from long-term-care facilities, patients with diseases of the skin, subcutaneous tissue, and breast, and obstetrical admissions.
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.
c For 1994 and 1997, rate biased in unknown direction because diagnosis codes 438.2x-438.5x used to exclude discharges from the numerator and denominator became effective Oct. 1, 1997; thus, they could not be used in 1994 and in quarters 1 through 3 of 1997.
