Unchanged incidence of major adverse events amidst rising surgical interventions for osteoporotic vertebral fractures, 2015-2021.

This study investigated treatment trends and major adverse events in patients hospitalized for osteoporotic vertebral fracture (OVF). The frequency of surgical interventions for OVF increased significantly, but this did not decrease major adverse events. The findings underscore the necessity for reevaluating OVF management strategies. PURPOSE: Osteoporotic vertebral fracture (OVF) is a common condition in the aging population, often leading to increased morbidity and mortality. Here, we analyzed treatment trends and incidence of major adverse events in patients hospitalized for OVF.

methodsWe conducted a cross-sectional descriptive study, using a large Japanese hospital administrative database. The cohort included hospitalized patients aged 65 years or older, admitted for OVF from January 2015 to December 2021. The primary outcomes were the trend in the proportion of the patients undergoing surgery for OVF and the incidence of major adverse events within 30 days of admission. As a secondary outcome, we evaluated the trend in hospitalization costs.

resultsThe study cohort consisted of 14,714 patients, with a mean age of 82.4 years. There was a significant increase in surgical interventions for OVF, from 3.7% of patients in 2015 to 9.8% in 2021 (p < 0.001). The incidence of major adverse events remained unchanged, with a risk ratio of 1.09 (95% confidence interval, 0.88 to 1.35) in 2021 compared to 2015. Average hospitalization costs increased significantly, from $7,570.6 (SD 6,047.0) in 2015 to $9,502.9 (SD 7,231.5) in 2021 (p < 0.001).

conclusionDespite a significant increase in the proportion of surgical intervention for OVF, no reduction in the risk of major adverse events was observed between 2015 and 2021. Surgeons and policy makers need to interpret these findings and work towards an optimized approach to the management of OVF in the aging population.
