“…The examination of GBS colonization data across the five hospitals revealed an overall rate of 21.70% which was similar to average rates in international research (Edwards et al, 2019;Jisuvei et al, 2020;Ramesh Babu et al, 2017;Szylit et al, 2020) and consistent with results of previous Australian studies (Braye et al, 2019;Furfaro et al, 2019;Moorhead et al, 2019). No studies were located to relate findings of the current study in relation to the different models of care (non-and midwifery led care).…”

Aims 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). Design 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. Conclusion Adherence to screening and management guidelines of maternal GBS colonization in pregnancy is lower within the MMC when compared with the NMMC. Impact 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.

Background: Group β Streptococcus (GBS) colonization among pregnant females is common and is regarded as a substantial cause of neonatal diseases if not treated properly. Thus, we aimed to evaluate the diagnostic performance of two chromogenic media (Granada agar and ChromID StreptoB agar) for screening of GBS in pregnant women between 35-37 weeks of gestation. In addition, we determined their susceptibility profile for guiding the antimicrobial prophylaxis for cases of GBS colonized pregnant women. Method: This study included 112 vagino-rectal swabs collected in duplicates from 112 pregnant women between 34-37 weeks of gestation. All swabs were incubated in enrichment broth for 18 hours followed by subculture on blood agar, ChromID strepto B, and Granada agar. Growth of confirmed GBS isolate was subjected to antimicrobial susceptibility testing (AST) to penicillin, vancomycin, clindamycin, erythromycin, and cefotaxime by disc diffusion method. Results: The frequency rate of GBS among Egyptian pregnant females was (25.89%). Granada agar was the most accurate among the tested media (98.21%) versus ChromID (96.4%). We observed a high resistant rate for all the tested antibiotics. Conclusion: The examined chromogenic media showed promising results and proved to have the potential to be implemented as a screening method for GBS in pregnant women. Regarding the antibiotics' resistance pattern, our results can be an indicator that it is no longer suitable to use the antibiotics empirically without testing. As antibiotic treatment failure is likely, it became inevitable to perform AST before starting any antibiotic to identify the most appropriate treatment for colonized pregnant women.
