Hospitals are establishing procedure services to address resident training and patient safety. We examined whether a hospitalist procedure service affects a patient’s hospital length of stay (LOS) and the time from admission to paracentesis (A2P). We queried our electronic medical records for all inpatient peritoneal fluid samples from July 1, 2016, to May 31, 2019. LOS and A2P time were compared among patients who had paracentesis by the procedure service, by residents, or by radiology. Of the 1,321 procedures, 509 (38.5%) were performed by the procedure service. In the adjusted analysis, as compared with procedure service, the group that underwent paracentesis by the radiology service had a 27% longer LOS (95% CI, 2%-58%) and 40% longer A2P time (95% CI, 5%-87%). The resident group had shorter A2P (–19%; 95% CI, –33% to 0.2%; P = .05) than the procedure service group but similar LOS. To our knowledge, this is the first study that suggests patient-centered benefits of a hospitalist procedure service.

医院正在建立程序服务以解决住院医师培训和患者安全问题。我们检查了住院医师程序服务是否会影响患者的住院时间 (LOS) 和从入院到穿刺的时间 (A2P)。我们查询了 2016 年 7 月 1 日至 2019 年 5 月 31 日期间所有住院患者腹膜液样本的电子病历。比较了通过手术服务、住院医师或放射科进行腹腔穿刺术的患者的 LOS 和 A2P 时间。在 1,321 次手术中，509 次 (38.5%) 由手术服务执行。在调整后的分析中，与手术服务相比，接受放射科服务进行腹腔穿刺的组的 LOS（95% CI，2%-58%）和 A2P 时间（95% CI，5%）延长了 40% -87%）。居民组的 A2P 较短（–19%；95% CI，–33% 至 0.2%；P = .05) 比过程服务组但相似的 LOS。据我们所知，这是第一项表明住院医师程序服务以患者为中心的好处的研究。
