Abstract：
OBJECTIVE: To investigate Group B Streptococcus (GBS) colonization in pregnancy; adherence to antenatal GBS screening and adherence to the intrapartum antibiotics protocol within two models of care (midwifery and non-midwifery led).
METHODS: This retrospective quantitative study has employed a descriptive design using administrative health data.
METHODS: Data from five maternity hospitals in metropolitan and regional Western Australia that included 22,417 pregnant women who gave birth between 2015 and 2019 were examined, applying descriptive statistics using secondary data analysis.
RESULTS: The study revealed an overall GBS colonization rate of 21.7% with similar rates in the different cohorts. A lower adherence to screening was found in the midwifery led model of care (MMC, 68.76%, n = 7232) when compared with the non-midwifery led model of care (NMMC, 90.49%, n = 10,767). Over the 5 years, screening rates trended down in the MMC with stable numbers in the counterpart. Adherence in relation to intrapartum antibiotic prophylaxis revealed discrepant findings between the study groups.
CONCLUSIONS: Adherence to screening and management guidelines of maternal GBS colonization in pregnancy is lower within the MMC when compared with the NMMC.
CONCLUSIONS: This is the first cohort study to describe the adherence to the recommended Western Australian GBS screening guidelines in the two different models of care. Findings may assist in the guidance and improvement of clinical protocols as well as the planning of clinical care in relation to GBS screening to reduce the risk of neonatal GBS infection.

摘要：
目的：调查B组链球菌（GBS）在妊娠期定植、产前GBS筛查依从性和产时抗生素方案在两种护理模式（助产和非助产）中的依从性。
方法：这项回顾性定量研究采用了使用行政卫生数据的描述性设计。
方法：来自西澳大利亚州和地区的五家妇产医院的数据，其中包括2015年至2019年期间分娩的22,417名孕妇。使用二次数据分析应用描述性统计。
结果：研究显示GBS的总体定植率为21.7%，在不同的队列中相似。在助产主导的护理模式中发现对筛查的依从性较低(MMC，68.76%,n=7232)与非助产主导的护理模式(NMMC，90.49%,n=10767）。五年来,MMC的筛查率呈下降趋势，相应的筛查率稳定。与产时抗生素预防相关的坚持表明研究组之间的发现存在差异。
结论：与NMMC相比，MMC对孕妇GBS定植的筛查和管理指南的依从性较低。
结论：这是第一个描述在两种不同的护理模式中遵守推荐的西澳大利亚州GBS筛查指南的队列研究。研究结果可能有助于指导和改进临床方案以及与GBS筛查有关的临床护理计划，以降低新生儿GBS感染的风险。
