Impact of Hospital Volume on Long-Term Outcomes After Endovascular Therapy for Peripheral Artery Disease.

The association between hospital volume of endovascular therapy and long-term adverse clinical outcomes remains unclear. The present analyses showed no significant differences in 12-month amputation rates among the hospital volumes, whereas higher-volume quartiles were significantly associated with decreased 12-month all-cause death rates and composite outcome. There was also a positive association in the length of stay between the first quartile volume and the others, while no significant difference in total health care costs among the quartiles was observed. Further investigations are needed, including insights into operator volume and procedural characteristics, to clarify the relationship between hospital volume and long-term adverse outcomes.
