EVALUATION OF A DECADE OF ONCOLOGICAL-ORTHOPEDIC PROCEDURES IN BRAZIL (2015-2024) AND THE IMPACT OF COVID-19

To evaluate the regional distribution of hospital admission authorizations (AIH), total and average hospitalization cost (AHC), average length of stay, number of deaths and mortality rate related to oncological-orthopedic procedures funded by the Unified Health System (SUS) between 2015 and 2024, with an emphasis on the impact of the COVID-19 pandemic.

Ecological study with time series based on data obtained from the SUS Hospital Information System, analyzed by Brazilian regions in the pre-pandemic, pandemic and post-pandemic periods. Regional differences were calculated using ANOVA or Kruskal-Wallis. The impact of the pandemic was analyzed using T-tests and ARIMA with intervention. Statistical analysis was performed in R.

9,120 AIHs were recorded, mostly in the Southeast (4,375) and South (2,252) regions. Multiple regional variations were found for all the variables evaluated. Only the AHC was impacted - there was an increase in costs per procedure; The other variables maintained the trend after the beginning of the pandemic.

Despite the increase in the AHC, we did not observe significant variation in the number of AIH, ALS, and MR when analyzing the pre-pandemic and pandemic periods, suggesting that there was no direct impact on the performance of the analyzed procedure.
