Abstract：
BACKGROUND: Pancreaticoduodenectomy (PD) is associated with better outcomes in high-volume hospitals. However, it is unknown whether and to what extent the improved performance of high-volume hospitals may be associated with racial and socioeconomic factors, which have been shown to impact operative and postoperative outcomes in major surgeries. This review aims to identify the differences in racial and socioeconomic characteristics of patients who underwent PD surgery in high- and low-volume hospitals.
METHODS: PubMed, Cochrane, and Web of Science were systematically searched between May 1, 2023 and May 7, 2023 without any time restriction on publication date. Studies that were conducted in the United States and had a direct comparison between high- and low-volume hospitals were included.
RESULTS: A total of 30 observational studies were included. When racial proportions were compared by hospital volume, thirteen studies reported that compared to high-volume hospitals, a higher percentage of racial minorities underwent PD in low-volume hospitals. Disparities in traveling distance, education levels, and median income at baseline between high- and low-volume hospitals were reported by four, three, and two studies, respectively.
CONCLUSIONS: A racial difference at baseline between high- and low-volume hospitals was observed. Socioeconomic factors were less frequently included in existing literature. Future studies are needed to understand the socioeconomic differences between patients receiving PD surgery in high- and low-volume hospitals.

摘要：
背景：胰十二指肠切除术（PD）在高容量医院中与更好的预后相关。然而,尚不清楚大批量医院的绩效改善是否以及在多大程度上可能与种族和社会经济因素有关，已被证明会影响大型手术的手术和术后结果。这篇综述旨在确定在大批量和小批量医院接受PD手术的患者的种族和社会经济特征的差异。
方法：PubMed，科克伦,和WebofScience在2023年5月1日至2023年5月7日之间进行了系统搜索，对发布日期没有任何时间限制。包括在美国进行的研究，并在高容量和低容量医院之间进行了直接比较。
结果：共纳入30项观察性研究。当按医院数量比较种族比例时，13项研究报告说，与高容量医院相比，在低容量医院接受PD的种族少数群体比例较高.旅行距离的差异，教育水平,高数量医院和低数量医院的基线收入中位数由四家报告，三,和两项研究，分别。
结论：在高和低容量医院之间观察到基线的种族差异。现有文献中较少包含社会经济因素。需要进一步的研究来了解在高容量和低容量医院接受PD手术的患者之间的社会经济差异。
