How do you assess the safety of a delivery ward? Philosophy Each labour ward must decide what they are trying to achieve Everyone must be aware of it Normality needs to be defined
National Maternity Hospital Philosophy Curtailment of duration of exposure to stress, with avoidance of the physical and emotional trauma, which is likely to follow prolonged labour The prevention of prolonged labour BMJ 1969; 2:477-480.
National Maternity Hospital- normal labour Described as when a baby is born vaginally, by the efforts of the mother, within a reasonable timespan, provided no harm befalls either party as a result of their experience. Twelve hours is regarded a reasonable time span. Active Management of Labour BMJ 1973; 3:135-137
How do you assess the safety of a delivery ward? Leadership Clear lines of responsibility Delegation Ability to encourage communication Ability to encourage response and change Ability to encourage a disciplined approach
How do you assess the safety of a delivery ward? Multidisciplinary approach Clear lines of responsibility and hierarchial discipline must be combined with good working relationships within and between the different disciplines Nothing must be allowed to divide professionals
How do you assess the safety of a delivery ward? Key decision making Need to be clearly highlighted Clear delegation and responsibility Consistency
How do you assess the safety of a delivery ward? Failsafe mechanisms No isolation of care Continual communication Ability to access most senior staff
How do you assess the safety of a delivery ward? Key processes and decisions in labour and delivery Pre-labour Caesarean section Induction of labour Diagnosis of labour Maternal and fetal welbeing Rupture of membranes Use of oxytocin and philosophy on dystocia Management of second stage Operative delivery Management of third stage
How do you assess the safety of a delivery ward? Outcome Quality is related to outcome and outcomes guide processes
Safety and Quality in Labour and Delivery Should currently be measured in terms of available validated information
Epidemiology of Perinatal Outcome We need to classify all perinatal outcome so that objective comparisons can be made of fetal and maternal outcomes over time in one unit and between different units both nationally and internationally
But to do that We need a consistent and objective structure within which we can examine fetal and maternal outcomes
Classification systems Principles for classification system It must be simple, easy to implement, informative and useful The groups must be Objectively not subjectively defined, mutually exclusive and totally inclusive Must be prospectively determined, clinically relevant, identifiable, totally accountable and replicable It must be universal, robust and self validating Must be able to incorporate other variables and outcomes
Classification must be able to incorporate other variables related to caesarean section rates and other outcomes Significant epidemiological factors Age, BMI, Fetal weight, Previous medical history Casemix Maternal and fetal events, outcomes and complications together with indications Organisational systems Economics

Classifying Perinatal Outcome – the 10 Groups Previous obstetric record Nulliparous Multiparous without a scar Multiparous with a scar

National Maternity Hospital, Dublin Caesarean Sections - the 10 Groups 2005-2011
National Maternity Hospital, Dublin Caesarean Sections - the 10 Groups 2005-2011 Total number of caesarean sections over the overall total number of women Number of caesarean sections over the total number of women in each group
Size of each group is the total number of women in each group divided by the overall total number of women National Maternity Hospital, Dublin Caesarean Sections - the the 10 Groups 2005-2011
CS rate in each group is worked out for each group by dividing the number of caesarean sections by the total number of women in each group National Maternity Hospital, Dublin Caesarean Sections - the 10 Groups
Absolute contribution of each group to the overall CS rate is worked out by dividing the number of CS in each group by the overall population of women This will depend on the size of the group as well as the CS rate in each group National Maternity Hospital, Dublin Caesarean Sections - the 10 Groups
Groups 1,2 and 5 contribute to two thirds of all caesarean section rates and are the source of biggest variation between units National Maternity Hospital, Dublin Caesarean Sections - the 10 Groups
National Maternity Hospital, Dublin 2008 Caesarean Sections - the 10 Groups Groups 6, 7, 8, 9, 10. Small groups, high CS rates but small overall contributions to the total CS rate and very similar between different units
Philosophy of the 10 Group Classification Based on the premise that all information (epidemiological, maternal and fetal events and outcomes, cost and organisational) will be more clinically relevant by stratifying them using the 10 groups
The 10 Group Classification- and the advantage of standardisation Any differences in sizes of groups or outcome are either due to Poor data quality Differences in significant epidemiological factors Differences in practice
Simplicity- of process and audit Timing of artificial rupture of the membranes Use of oxytocin Audit of caesarean section in labour (dystocia) Vaginal birth after caesarean section Induction of labour
Amniotomy is performed at the diagnosis of labour To assess the fetal condition at the start of labour Determine which fetuses need continuous electronic monitoring Other beneficial effects Shortens the labour Decreases need for oxytocin
Use of oxytocin - essentials Safe Discussed and consensus achieved Strict implementation Audited Reviewed
Terminology Acceleration (augmentation) of labour Induction of labour Uterine tachysystole Over contracting Uterine hypertonus A prolonged contraction Uterine hyperstimulation When either condition leads to a non reassuring fetal heart rate pattern.
Concentration, maximum dose and rate of increase Concentration 10iu in 1L (Probably most common) 30mls equivalent to 5mu Rate of increase30 mls/15mins (5mu/15 mins) Maximum dose 180mls/hr (30mu/min)
Concentration, maximum dose and rate of increase Is not the main issue The issue is the effect on the fetus, the uterus, how often you use it and other events and outcomes
Monitoring contractions No more than 5 contractions in 10 minutes (most common) Nulliparous No more than 7 contractions in 15 minutes (NMH) Multiparous No more than 5 contractions in 15 minutes (NMH) Longer period of time to assess contractions Less maximum contractions over 30 minutes
