The purpose of this study was to determine the effect of hospital volume on long-term survival for women with breast cancer.
Survival analysis and proportional-hazard modeling were used to assess 5-year survival and risk of death, adjusting for clinical and sociodemographic variables.
At 5 years, patients from very low-volume hospitals had a 60% greater risk of all-cause mortality than patients from high-volume hospitals.
Hospital volume of breast cancer surgical cases has a strong positive effect on 5-year survival. Research is needed to identify whether processes of care, especially postsurgical adjuvant treatments, contribute to survival differences.
本研究旨在确定医院规模对乳腺癌女性患者长期生存的影响。
采用生存分析和比例风险模型评估5年生存率和死亡风险,并对临床和社会人口统计学变量进行调整。
5年后,来自低手术量医院的患者全因死亡率比来自高手术量医院的患者高60%。
乳腺癌手术病例的医院规模对5年生存率有显著的积极影响。需要开展研究以确定护理过程,尤其是术后辅助治疗,是否导致了生存差异。
