Hip replacement
Without complications or comorbidities

Hip replacements, also known as hip arthroplasty, are most commonly performed to restore joint function following damage caused by arthritis. The data presented here relate to costs incurred by a hospital for patients who were admitted for a hip replacement without complications or comorbidities.

In 2011–12, there were 6,729 hip replacements without complications or comorbidities in major metropolitan and major regional public hospitals.

CACost per Admission

Across all major metropolitan hospitals, the average cost of a hip replacement was $19,400. The average cost of a hip replacement ranged from $12,500 at one hospital to $25,600 at another hospital.

Across all major regional hospitals, the average cost of a hip replacement was $18,900. The average cost of a hip replacement ranged from $12,000 at one hospital to $25,300 at another hospital.

LOSLength of Stay

A previous Authority report showed the average length of stay for a hip replacement in 2011–12 was 6.4 days.7 At major metropolitan hospitals, the average length of stay ranged from 3.8 to 15.0 days, and at major regional hospitals the average length of stay ranged from 3.2 to 9.6 days.7

By comparing the cost of a patient’s hip replacement 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 12).

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