JOURNAL OF OBSTETRICS AND GYNAECOLOGY CANADA 2020; 42:977-983. [PMID: 32418858 DOI: 10.1016/j.jogc.2020.01.023] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2019] [Revised: 01/15/2020] [Accepted: 01/15/2020] [Indexed: 01/01/2023]
Abstract
OBJECTIVES To analyze risk factors for the presence of sexually transmitted and blood-borne infections (STBBIs) in pregnancy and to determine whether pregnant women with STBBIs are more likely to experience adverse pregnancy outcomes. METHODS This retrospective cohort study involved analyzing the electronic records of 3460 pregnant women followed at Sainte-Justine Hospital in Montréal, Québec, between March 2017 and January 2019. An outcome is defined as a pregnancy where the woman has at least one positive laboratory result for chlamydia, gonorrhea, syphilis, hepatitis B, or hepatitis C (i.e., has one or multiple STBBIs). We performed a logistic regression analysis to determine adjusted odds ratios (aORs) for the risk factors of STBBIs in pregnant women. RESULTS We identified 84 positive STBBI cases, an overall prevalence of 2.4% (95% CI 1.9-2.9). A logistic regression analysis showed the following factors to be significantly associated with the presence of STBBIs in pregnancy: age <20 years (OR 4.75; 95% CI 1.89-11.96), age 20-29 years (OR 2.38; 95% CI 1.37-4.14), Afro-Caribbean origin (OR 4.12; 95% CI 1.83-9.27), other non-Caucasian origin (OR 2.38; 95% CI 1.20-4.70), and history of STBBIs (OR 2.33; 95% CI 1.02-5.36). STBBIs were not significantly associated with social and material deprivation indices nor were they associated with low birth weight or preterm birth. CONCLUSION This study shows age <20 years, age 20-29 years, Afro-Caribbean or other non-Caucasian origin and history of STBBIs to be risk factors for the presence of STBBIs in pregnancy. These results will allow us to propose interventions to reduce STBBIs in women with common risk factors as part of a comprehensive approach to perinatal care.

Abstract
OBJECTIVE Determine the cost-effectiveness of screening all pregnant women aged 16-25 years for chlamydia compared with selective screening or no screening. DESIGN Cost effectiveness based on a decision model. SETTING Antenatal clinics in Australia. SAMPLE Pregnant women, aged 16-25 years. METHODS Using clinical data from a previous study, and outcomes data from the literature, we modelled the short-term perinatal (12-month time horizon) incremental direct costs and outcomes from a government (as the primary third-party funder) perspective for chlamydia screening. Costs were derived from the Medicare Benefits Schedule, Pharmaceutical Benefits Scheme, and average cost-weights reported for hospitalisations classified according to the Australian refined diagnosis-related groups. MAIN OUTCOME MEASURES Direct costs of screening and managing chlamydia complications, number of chlamydia cases detected and treated, and the incremental cost-effectiveness ratios were estimated and subjected to sensitivity analyses. RESULTS Assuming a chlamydia prevalence rate of 3%, screening all antenatal women aged 16-25 years at their first antenatal visit compared with no screening was $34,931 per quality-adjusted life-years gained. Screening all women could result in cost savings when chlamydia prevalence was higher than 11%. The incremental cost-effectiveness ratios were most sensitive to the assumed prevalence of chlamydia, the probability of pelvic inflammatory disease, the utility weight of a positive chlamydia test and the cost of the chlamydia test and doctor's appointment. CONCLUSION From an Australian government perspective, chlamydia screening of all women aged 16-25 years old during one antenatal visit was likely to be cost-effective compared with no screening or selective screening, especially with increasing chlamydia prevalence. TWEETABLE ABSTRACT Chlamydia screening for all pregnant women aged 16-25 years during an antenatal visit is cost effective.

Abstract
Background Chlamydia trachomatis infections in pregnancy can cause maternal disease, adverse pregnancy outcomes and neonatal disease, which is why chlamydia screening during pregnancy has been advocated. The effectiveness of a screening program depends on the knowledge of health care professionals, women and partners and the acceptability for screening of the target population. We assessed the knowledge of chlamydia infection among pregnant women and their partners in the Netherlands, their attitudes towards testing, and their experiences of being offered a chlamydia test. In addition, we evaluated the association between participants’ background characteristics and knowledge of chlamydia. Methods Pregnant women aged ≤ 30 years and their partners (regardless of their age) attending one of the participating primary midwifery care practices in the Netherlands were invited to participate. All participants completed a questionnaire, pregnant women provided a vaginal swab and partners provided a urine sample to test for C. trachomatis. Results In total, 383 pregnant women and 282 partners participated in the study of whom 1.9% women and 2.6% partners tested chlamydia positive. Participants had high levels of awareness (92.8%) of chlamydial infection. They were knowledgeable about the risk of chlamydia infection; median knowledge score was 9.0 out of 12.0. Lower knowledge scores were found among partners (p-value <0.001), younger aged (p-value 0.02), non-western origin (p-value <0.001), low educational level (p-value <0.001), and no history of sexually transmitted infections (p-value <0.001). In total, 78% of respondents indicated that when pregnant women are tested for chlamydia, their partners should also be tested; 54% believed that all women should routinely be tested. Pregnant women more often indicated than partners that testing partners for chlamydial infection was not necessary (p-value <0.001). The majority of pregnant women (56.2%) and partners (59.2%) felt satisfied by being offered the test during antenatal care. Conclusion Pregnant women and their partners were knowledgeable about chlamydial infection, found testing, both pregnant women and their partners, for chlamydia acceptable and not stigmatizing.

Abstract
BACKGROUND Chlamydia trachomatis infection in pregnancy may lead to adverse pregnancy outcomes. In the Netherlands, testing for C. trachomatis is based on risk assessment. We assessed midwives' knowledge, test practices, assessment of risk behavior, and attitudes regarding testing for C. trachomatis infection during pregnancy. We evaluated the association between midwives' characteristics and their knowledge of C. trachomatis infection in terms of symptomatology and outcomes. METHODS This was a cross-sectional study among primary care midwives in the Netherlands. Between September and November 2011, midwives from all Dutch primary care midwifery practices were invited to complete a questionnaire about C. trachomatis infection. RESULTS Of the 518 midwives invited to participate in this study, 331 (63.9%) responded. The overall median knowledge score for questions about symptomatology and outcomes was 10 out of a maximum score of 15. The median knowledge score was higher among midwives in urban areas. In total, 239 (72.2%) midwives reported testing pregnant women for C. trachomatis. The primary reason for testing was a request by the woman herself (96.2%), followed by symptoms of infection (89.1%), risk behavior (59.3%), and risk factors for infection (7.3%). Almost 25% of midwives showed positive attitudes towards universal screening for C. trachomatis. CONCLUSIONS Midwives were knowledgeable about symptoms of infection, but less about outcomes. Midwives test pregnant women for C. trachomatis mainly on the women's request. Otherwise, testing is based on symptoms of infection rather than on known risk factors. This may contribute to under-diagnosis and under-treatment, leading to maternal, perinatal, and neonatal morbidity.

Abstract
Introduction Implementation of an in-house polymerase chain reaction (PCR) multiplex assay by West of Scotland Specialist Virology Centre to improve sample processing means all viral eye swabs are now routinely tested for Adenovirus, Herpes simplex, Varicella and Chlamydia. Concern was raised regarding subsequent management and sexual health attendance for Chlamydia-positive patients identified in eye casualty. Methods A retrospective review of virology results identified 76 Chlamydia-positive patients from 1914 eye swabs (4%) from May 2007 to April 2008. Of these results, 12 originated from Glasgow eye casualty and available clinical notes were cross-referenced with the sexual health network (Sandyford). Results Identified issues included no documentation of implications of testing, poor communication of positive results and poor referral pathways to sexual health for assessment; all leading to inadequate management. A shared care network was created to address these issues. A designated sexual health advisor was identified to improve sexual health referral, specialist assessment, standardised management and contact tracing. Re-audit showed more consistent follow-up. Conclusion New PCR technology has resulted in a shared care approach to address corresponding implications of testing. Effective communication with a structured protocol and a central point of contact has improved follow-up and ensures appropriate best practice management of chlamydial conjunctivitis.

Abstract
BACKGROUND Chlamydia trachomatis is a common sexually transmitted infection in Australia. This report aims to measure the burden of chlamydia infection by systematically reviewing reports on prevalence in Australian populations. METHODS Electronic databases and conference websites were searched from 1997-2011 using the terms 'Chlamydia trachomatis' OR 'chlamydia' AND 'prevalence' OR 'epidemiology' AND 'Australia'. Reference lists were checked and researchers contacted for additional literature. Studies were categorised by setting and participants, and meta-analysis conducted to determine pooled prevalence estimates for each category. RESULTS Seventy-six studies met the inclusion criteria for the review. There was a high level of heterogeneity between studies; however, there was a trend towards higher chlamydia prevalence in younger populations, Indigenous Australians, and those attending sexual health centres. In community or general practice settings, pooled prevalence for women <25 years in studies conducted post-2005 was 5.0% (95% CI: 3.1, 6.9; five studies), and for men <30 years over the entire review period was 3.9% (95% CI: 2.7, 5.1; six studies). For young Australians aged <25 years attending sexual health, family planning or youth clinics, estimated prevalence was 6.2% (95% CI: 5.1, 7.4; 10 studies) for women and 10.2% (95% CI: 9.5, 10.9; five studies) for men. Other key findings include pooled prevalence estimates of 22.1% (95% CI: 19.0, 25.3; three studies) for Indigenous women <25 years, 14.6% (95% CI: 11.5, 17.8; three studies) for Indigenous men <25 years, and 5.6% (95% CI: 4.8, 6.3; 11 studies) for rectal infection in men who have sex with men. Several studies failed to report basic demographic details such as sex and age, and were therefore excluded from the analysis. CONCLUSIONS Chlamydia trachomatis infections are a significant health burden in Australia; however, accurate estimation of chlamydia prevalence in Australian sub-populations is limited by heterogeneity within surveyed populations, and variations in sampling methodologies and data reporting. There is a need for more large, population-based studies and prospective cohort studies to compliment mandatory notification data.

Abstract
Objective Antenatal testing for specified sexually transmissible infections (STIs) and blood-borne viruses (BBVs) is recommended by the Royal Australian and New Zealand College of Obstetricians and Gynaecologists (RANZCOG). In 2007, the Department of Health, Western Australia (DoHWA) issued an operational directive (OD) recommending universal testing for chlamydia and additional testing for women in the STI endemic regions of Western Australia (WA). To assess adherence to these guidelines, seven WA public hospitals were audited. Design and setting: Demographic details and testing information of the last 200 women who gave birth immediately before 30 June 2007 (baseline audit) and 30 June 2010 (follow-up audit) were obtained from each hospital’s antenatal records. Results: Data from 2718 women who delivered at ≥36 weeks’ gestation were analysed (baselinen = 1353; follow-upn = 1365). Testing at the first antenatal visit in accordance with the guidelines improved over time (RANZCOG: 68–74%; χ2-test = 13.96, d.f. = 1, P < 0.001; DoHWA OD: 12–40%; χ2-test = 279.71, d.f. = 1, P < 0.001). Retesting at 28–36 weeks’ gestation in the STI endemic regions improved for chlamydia (3–10%; χ2-test = 17.40, d.f. = 1, P < 0.001) and gonorrhoea (3–7%; χ2-test = 6.62, d.f. = 1, P < 0.05), but not for syphilis or HIV. Chlamydia prevalence was 3% and 8% among nonAboriginal and Aboriginal women, respectively. Conclusion: The proportion of women delivering in WA public hospitals who had antenatal STI and BBV tests improved after publication and promotion of the OD.
