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.
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。
