Kidney and urinary tract infections
With complications or comorbidities

Kidney and urinary tract infections occur frequently but can occasionally be severe enough to require treatment in hospital. The data presented here relate to costs incurred by a hospital for patients who were admitted for kidney or urinary tract infections with complications or comorbidities.

In 2011–12, there were 8,821 admissions for kidney and urinary tract infections with complications or comorbidities in major metropolitan and major regional public hospitals.

CACost per Admission

Across all major metropolitan hospitals, the average cost per admission for kidney and urinary tract infections with complications was $9,000. The average cost per admission ranged from $5,500 at one hospital to $14,600 at another hospital.

Across all major regional hospitals, the average cost per admission for kidney and urinary tract infections with complications was $10,000. The average cost per admission ranged from $7,200 at one hospital to $12,200 at another hospital.

LOSLength of Stay

A previous Authority report showed the average length of stay for kidney and urinary tract infections with complications in 2011–12 was 7.5 days.7 At major metropolitan hospitals, the average length of stay for kidney and urinary tract infections with complications ranged from 5.2 to 9.5 days, and at major regional hospitals the average length of stay ranged from 5.5 to 10.1 days.7

By comparing the cost of a patient’s admission for kidney and urinary tract infections with complications to their length of stay it is possible to assess the incremental cost that each additional day(s) spent in hospital contributes to the patient’s costs of care (Figure 11).

It is important to note that these costs do not reflect the total costs of treating this condition. The report considers only the subset of total costs that are fully comparable between hospitals. For example, it excludes property, plant and equipment costs.
