HarperGroup A b-haemolytic strep<strong>to</strong>coccus(Strep<strong>to</strong>coccus pyogenes): learningpointsThe number of <strong>maternal</strong> <strong>deaths</strong> from Group A b-haemolyticstrep<strong>to</strong>coccus (Strep<strong>to</strong>coccus pyogenes) infectionhas been increasing over the past 10 years.Group A strep<strong>to</strong>coccus is typically community basedand 5–30% of the population are asymp<strong>to</strong>matic carrierson skin or in throat. 1 It is easily spread by person-<strong>to</strong>personcontact or by droplet spread from a person withinfection.Strep<strong>to</strong>coccal sore throat is one of the most commonbacterial infections of childhood, and all of the motherswho died from Group A strep<strong>to</strong>coccal sepsis eitherworked with, or had, young children. Several mothersor family members had a his<strong>to</strong>ry of recent sore throa<strong>to</strong>r respira<strong>to</strong>ry infection.Contamination of the perineum is more likely when awoman or her family or close contacts have a sorethroat or upper respira<strong>to</strong>ry infection as the organismmay be transferred from the throat or nose via herhands <strong>to</strong> her perineum. Antenatal education shouldraise awareness of this and the importance of good personalhygiene and washing hands before and after usingthe lava<strong>to</strong>ry or changing sanitary <strong>to</strong>wels.IntroductionUnlike many other causes of direct <strong>maternal</strong> mortality,<strong>deaths</strong> from genital tract sepsis have risen rather thandeclined this triennium. Indeed, genital tract sepsis hasbecome the leading cause of Direct <strong>maternal</strong> death in theUK for the first time since these Confidential Enquiriesin<strong>to</strong> Maternal Deaths commenced in 1952. This is a causefor concern, particularly as it has occurred against a backgroundof an overall decrease in <strong>maternal</strong> mortality. But,as discussed in this Chapter, many of these <strong>deaths</strong> werefrom community-aquired Group A strep<strong>to</strong>coccal disease,mirroring an overall background increase in mortality fromthis disease in the general population. 2 For many of thesewomen, the outcome was unavoidable despite excellent carebecause of the rapid course and late presentation of the illness.However, in others, possible opportunities <strong>to</strong> savelives may have been missed and lessons remain <strong>to</strong> belearnt.Sepsis should never be underestimated. Its course isoften insidious and staff need <strong>to</strong> be aware that women withserious illness, especially sepsis, may appear deceptively wellbefore suddenly collapsing, often with little or no warning.Once established, sepsis may be fulminating and irreversiblewith rapid deterioration in<strong>to</strong> septic shock, disseminatedintravascular coagulation and multi-organ failure. The clinicalcourse is often so short, especially in Group A strep<strong>to</strong>coccalinfection, that by the time women present <strong>to</strong>hospital, it is <strong>to</strong>o late <strong>to</strong> save them. As a healthcare workersaid: ‘Even with modern medicine, an experienced team ofdoc<strong>to</strong>rs and midwives could not save a young pregnantwoman. The rapid deterioration caused by the overwhelmingsepsis, despite desperate attempts <strong>to</strong> resuscitate her, willnever be forgotten.’Sepsis is complex, incompletely unders<strong>to</strong>od, often difficult<strong>to</strong> recognise and manage, and presents a continuingchallenge. Some <strong>deaths</strong> will always be unavoidable, but bettertraining, a structured approach, good care in the community,and, in hospital, prompt investigation andtreatment, particularly immediate intravenous antibiotictreatment and early involvement of senior obstetricians, anaesthetistsand critical care consultants, may help in future<strong>to</strong> save some lives. Further information about the pathophysiology,clinical features and management of sepsis isgiven in Chapter 16 and should be read in conjunctionwith this chapter.Summary of key findings for <strong>2006</strong>–08The <strong>deaths</strong> of 29 women who died from genital tract sepsis,as traditionally defined by this Report, were reportedthis triennium. Of these, 26 Direct <strong>deaths</strong> are counted inthis Chapter and the remaining three, which were LateDirect <strong>deaths</strong> occurring more than 6 weeks after delivery,outside the international classification for <strong>maternal</strong> <strong>deaths</strong>,are counted in Chapter 12. One of these was also associatedwith haemorrhage. These three <strong>deaths</strong> are discussed herebecause the women concerned became ill before or soonafter delivery and they may contribute <strong>to</strong> the overall lessons<strong>to</strong> be learnt from these cases.The mortality rate from sepsis for this triennium, <strong>2006</strong>–08, is 1.13 (95% CI 0.77–1.67) per 100 000 maternities,compared with 0.85 (95% CI 0.54–1.35) for the last reportand the rate of 0.65 (95% CI 0.38–1.11) for 2000–02,although this increase has not reached statistical significance(P = 0.1). These rates are shown in Table 7.1 andFigure 7.1.The main reason for the rise in <strong>maternal</strong> mortalityfrom sepsis in this triennium is the increased number of<strong>deaths</strong> caused by community-acquired b-haemolytic strep<strong>to</strong>coccusLancefield Group A (Strep<strong>to</strong>coccus pyogenes).Most women had signs and symp<strong>to</strong>ms of severe sepsis bythe time they presented <strong>to</strong> hospital. Although there hasbeen much concern in recent years about hospitalacquiredinfection with ‘superbugs’, there is no evidenceof this apart from one woman who was already known <strong>to</strong>be a carrier.86 ª <strong>2011</strong> Centre for Maternal and Child Enquiries (CMACE), BJOG 118 (Suppl. 1), 1–203

Deaths from genital tract sepsis, rates per 100 000 maternities; UK: 1985–<strong>2008</strong>The women who diedThe ages of the women who died, including the three whodied later in the postnatal period, ranged from 15 <strong>to</strong>41 years with a median age of 34 years. Most were in stablefamily relationships with no significant social issues. Tenwere from minority ethnic groups, six of whom were asylumseekers or recent immigrants, including one migrantworker from a new European Union country who spokeno English. One such mother was not booked until late inher pregnancy although she had regularly attended theEmergency Department with pregnancy-related problems.Four women did not speak English, and, in all cases, closefamily members provided interpretation. The inappropriatenessof this and lack of interpretation services is a recurringtheme in this Report and one for which an overallrecommendation has been made.Most women had normal body mass index (BMI) orwere slightly overweight with ranges between 18 and 35with a median of 23.5, but five had a BMI > 30. This differsfrom the last triennium where the majority of thewomen who died from sepsis were overweight or obese.Nine were primigravid. Eight women died from sepsisbefore 24 weeks of gestation, with loss of all fetuses. Twelvewomen had a vaginal delivery, and nine had a caesareansection after 24 weeks of gestation. Sixteen of their babiessurvived; there were five stillbirths.Substandard careSome mothers had excellent or outstanding care, but forothers there were missed opportunities for early intervention.Lessons can be learnt from the management of 18 ofthe 26 (69%) mothers who died during pregnancy or withinª <strong>2011</strong> Centre for Maternal and Child Enquiries (CMACE), BJOG 118 (Suppl. 1), 1–203 87
