## TL;DR

This study examines the costs and quality of life improvements for patients who had hip replacement surgery in a Brazilian hospital.

## Contribution

It provides new data on cost and quality of life outcomes specific to a Brazilian private hospital setting.

## Key findings

- Quality of life scores improved significantly over two years post-surgery.
- Male sex and younger age were associated with better quality of life outcomes.
- No association was found between total cost and quality of life improvement.

## Abstract

There are few studies in Brazil evaluating the quality of life and costs of patients undergoing total hip arthroplasty (THA).

(1) To describe the total cost, quality of life and functional scores of patients undergoing THA in a Brazilian private hospital; (2) to determine preoperative factors associated with quality of life and total cost; and (3) to evaluate the association between cost and quality of life.

Of the 1061 patients included, pre- and peri-operative data, total costs, pre- and post-operative functional scores (HOOS, WOMAC) and quality of life scores (EQ-5D) were collected over 2 years.

EQ-5D, HOOS and WOMAC improved from 0.492, 54.5 and 45.2, respectively, to 0.888, 90 and 5.9 at 1-year follow-up, and 0.892, 90.4 and 4.0 at 2-year follow-up. The average cost was R$43,324.22±11,323. Associations were observed between EQ-5D variation and male sex (RM=1.058; p=0.03) as well as age (RM=0.996; p<0.001). No association was found between total cost and EQ-5D.

The average cost of patients undergoing THA was R$43,324.22. There was an improvement in quality of life and function, an association between quality of life and male sex and age, however no association was found between total cost and quality of life.
