Six diagnostic categories each accounted for a million or more discharges. These were heart disease
million), delivery (4.0 million), psychoses (1.6 million), pneumonia
million), malignant neoplasms
million), and fractures (1.1 million) (figure 1).
The average length of stay was 2.6 days for delivery, 4.6 days for heart disease, 5.4 days for fractures, 5.5 days for pneumonia, 6.7 days for malignant neoplasms, and 8.0 days for psychoses (table 4).
Of the 4.4 million discharges hospitalized for heart disease, 2.8 million or 64 percent were patients 65 years of age or over (table 2). For the elderly, there were 787.3 discharges per 10,000 population with a first-listed diagnosis of heart disease (table 3).
Eleven percent of all discharges were hospitalized for respiratory diseases. Of these, 37 percent were diagnosed with pneumonia, 15 percent were diagnosed with asthma, 14 percent were diagnosed with chronic bronchitis, and 34 percent were diagnosed with other respiratory illnesses (figure 2).
The rate of malignant neoplasms among those 65 years and over was significantly higher than that of any of the other age groups analyzed for this report, but has been decreasing since 1990. The rates for inpatients under 45 years old and those aged 45–64 years old also have been decreasing over the same period (figure 3).
Nearly one-fifth (4 million) of female discharges were for childbirth (table 5).

During 2003, 43.9 million procedures were performed on hospital inpatients (table 8). Nationally, the rate of procedures was 1,515.7 per 10,000 population (table 9). For males, this rate was 1,228.3; for females, it was 1,792.2 per 10,000 population (table 11).
Almost three-fourths of all procedures were in four ICD–9–CM chapters:
