摘要

Objective

To analyze the temporal trend and regional distribution of hip arthroplasty procedures performed within Brazil’s Unified Health System (SUS) between 2014 and 2024, as well as associated costs, hospital stay, and in-hospital mortality.

Methods

This ecological time series study used SIH/SUS data on hip arthroplasties performed between 2014 and 2024. Surgical subgroups were classified according to SIGTAP codes. Annual rates standardized per 100,000 inhabitants were calculated and stratified by regions and states. Temporal trends were assessed using Pearson’s correlation. Mean hospital length of stay, annual costs, and in-hospital mortality were also analyzed.

Results

There was a progressive increase in national hip arthroplasty rates, from 1.85 to 28.23 per 100,000 inhabitants between 2014 and 2024. A significant upward trend was observed in most regions, notably in the Northeast (r = 0.68; p = 0.02). Marked inequalities were found, with higher rates in the South and Southeast and lower rates in the North and Northeast. Partial hip arthroplasty was the most frequent subgroup, accounting for most emergency procedures and the largest share of financial resources. Mean hospital stay varied among subgroups, with an overall average of 8.46 days. A significant reduction in in-hospital mortality was observed for partial arthroplasty.

Conclusion

Between 2014 and 2024, there was a substantial increase in hip arthroplasties performed in the SUS, with important regional inequalities and variations in costs and outcomes. These findings underscore the need for public policies to expand equitable access and optimize healthcare resource use.
