背景：在接受高风险癌症手术的患者中，在这些手术较多的医院，术后死亡率通常较低。我们进行了一项基于人群的研究，以估计在医院进行手术的次数（医院数量）与肺癌切除术后生存的关系程度。方法：我们研究了1985年至1996年间接受I、II或IIIA期非小细胞肺癌诊断的65岁或以上患者，这些患者居住在监测、流行病学和最终结果计划涵盖的10个研究区域中的1个，并在参与全国住院患者样本（2118名患者和76家医院）的医院接受手术。结果：医院手术量与患者生存率呈正相关(P
Background: Among patients who have undergone high-risk operations for cancer, postoperative mortality rates are often lower at hospitals where more of these procedures are performed. We undertook a population-based study to estimate the extent to which the number of procedures performed at a hospital (hospital volume) is associated with survival after resection for lung cancer.Methods: We studied patients 65 years old or older who received a diagnosis of stage I, II, or IIIA non-small-cell lung cancer between 1985 and 1996, resided in 1 of the 10 study areas covered by the Surveillance, Epidemiology, and End Results Program, and underwent surgery at a hospital that participates in the Nationwide Inpatient Sample (2118 patients and 76 hospitals).Results: The volume of procedures at the hospital was positively associated with the survival of patients (P
