A global perspective on management of bacterial infections in pregnancy: a systematic review of international guidelines
Abstrakt
INTRODUCTION: Maternal sepsis is a leading cause of maternal and neonatal mortality. Despite the availability of management protocols, there is disparity in case fatality rates for pregnancy-related sepsis compared to other maternity-related complications.
The main aim of this systematic review was to assess concordance between international evidence-based guidelines for the prevention and management of childbirth-related bacterial infections. MATERIAL AND METHODS: The PRISMA statement was followed during the conduct and reporting of this review.
PubMed was searched electronically from 2009 to November 2019 for clinical guidelines covering the topic of childbirth-related infections and specific searches for relevant guidelines on the websites of the top five international professional bodies most commonly identified by our searches. We did not apply any language restrictions.
Guidelines were included if they provided any information about the prevention or management of childbirth-related bacterial infections irrespective of whether the guideline stated a recommendation or not. Two independent reviewers undertook study selection, decisions about inclusion of selected guidelines and data extraction.
Extracted information was synthesized under the following topics: Asymptomatic bacteriuria; group B streptococcal infection (GBS); preterm premature rupture of membranes (P-PROM); intrauterine infection; procedures; maternal sepsis; miscellaneous. Concordance was defined as absence of contradictory information between the different guidelines with regards to a specific topic, subtopic or recommendation.
Quality of included guidelines was assessed against the AGREE II guideline reporting domains. RESULTS: A total of 43 guidelines were selected of which 11 were excluded leaving 32 guidelines that fulfilled our inclusion criteria.
None of the guidelines fulfilled all the quality assessment domains and 11 (34%) of the guidelines satisfied 1-2 of domains only. Two guidelines covered the topic of asymptomatic bacteriuria, nine for GBS, five for P-PROM and three covered each of intra-amniotic infections maternal sepsis, obstetric procedures and interventions topics.
The remaining guidelines covered miscellaneous topics. CONCLUSIONS: There was concordance between guidelines with regards to several aspects in the prophylaxis and treatment of bacteriological infections in pregnancy.
Nevertheless, there were several areas of discordance, some of which reached the extent of contradictory information as in the case of antenatal screening for GBS.
