Chapter 9: Guidelines for the Provision of Anaesthesia Services for an Obstetric Population 2019
Pregnancy and the time around the birth of a baby is usually an exciting time in the life of a family, but it also brings with it potential risks to mother and baby. We are fortunate in the United Kingdom to have a low maternal mortality rate (MMR) but we have seen a plateau in the UK’s MMR in the last triennium.4,7,6 Our continued national learning from the confidential review of every maternal death over the last seven decades has allowed us to determine where deficiencies in service provision have led to substandard or poor care and to identify areas where improvements to care can be made to reduce the risk for mothers and babies. It is vital that we use this shared learning and the currently available evidence to shape our provision of care to pregnant and recently delivered women, both here in the UK and with the wider population globally.
Working on delivery units can be incredibly rewarding for obstetric anaesthetists and the wider multidisciplinary team, but it can also be highly challenging and rapidly changing. It is not possible to identify all women or babies who are at risk of rapid deterioration, but we need to be able to respond appropriately and safely in the event of an emergency. Obstetrics accounts for a large proportion of the emergency surgery performed in hospitals.9,10 We have emphasised in these recommendations the importance of training and working as a team when delivering care in maternity units. This is truly a multidisciplinary workforce, where obstetricians, anaesthetists, neonatologists, midwives, theatre staff, anaesthetic assistants, and many others work closely alongside each other in situations that can be stressful. To ensure that teams can function effectively in this environment, they need to train together and have the appropriate infrastructure and necessary resources to meet these expectations.
The anaesthetist is now a well recognised and busy member of the delivery unit team. Approximately 60 per cent of women require anaesthetic intervention around the time of delivery of their baby, but the total anaesthetic involvement is higher. It is currently difficult to quantify other non-anaesthetic procedures that anaesthetists carry out on the delivery suite.11 Approximately 1 in 4 women deliver by caesarean section, and many more require anaesthetic care for operative/assisted deliveries and procedures during pregnancy or around the time of delivery. Anaesthetists are also involved in planning the care of high-risk women during the antenatal period. While most women are considered low risk at the start of their pregnancies, the obstetric population is changing. In 2015, the largest percentage increase in fertility rates was for women aged 40 and over (a group whom have been identified as at high risk of mortality in the recent MBRRACE report) and the incidence of obesity in this country continues to rise.4,13,14 The number or women who have had a previous caesarean delivery has risen, and with that comes the risks of complications related to placental adhesion and uterine rupture. More women with significant pre-existing conditions, e.g. congenital cardiac disease, are proceeding with their pregnancies, and they require specialised services to support them during this time. These recommendations outline areas where tertiary units are expected to take a lead role, but, as a pregnant woman may present to any unit, they should all be ready to recognise and manage the acutely deteriorating woman with pathways in place to obtain expert guidance when required.
Maternity services are subject to considerable patient expectation; through media, internet and educational resources, women and their families are often well informed about what to expect at delivery, and many are keen for a particular mode of delivery or type of analgesia. We have to deliver an anaesthetic service that is safe and effective, and that also aims to meet these expectations where appropriate.
We are expecting further National Institute for Health and Care Excellence guidelines on intrapartum care for the high risk maternity population to be published in 2019, along with Royal College of Anaesthetists’ guidance on managing critically ill women (updating recommendations made in ‘Providing equity of critical and maternity care for the critically ill pregnant or recently pregnant woman’).15,16 These are likely to influence the provision of care for high risk and acutely unwell women in the year to come after publication of this year’s Guidelines.
1. Staffing Requirements
The duty anaesthetist’s focus is the provision of care to women in labour or who, in the antenatal or postpartum period, require medical or surgical attention. The duty anaesthetist will be a consultant, an anaesthetic trainee or a staff grade, associate specialist and specialty (SAS) doctor.
To act as duty anaesthetist without direct supervision from a consultant, the anaesthetist should meet the basic training specifications and have attained the RCoA’s Initial Assessment of Competency in Obstetric Anaesthesia.22
There should be a duty anaesthetist immediately available for the obstetric unit 24/7. This person’s focus is the provision of care to women in labour or who, in the antenatal or postpartum period, require medical or surgical attention. The role should not include undertaking elective work during the duty period.23
Busier units should consider having two duty anaesthetists available 24/7, in addition to the supervising consultant.23
In units offering a 24-hour neuraxial analgesia service, the duty anaesthetist should be resident on the hospital site where neuraxial analgesia is provided (not at a nearby hospital).
The duty anaesthetist should have a clear line of communication to the supervising consultant at all times.
It is recognised that in smaller units, it may be difficult to have a duty anaesthetist exclusively dedicated to the delivery unit. If the duty anaesthetist has other responsibilities, these should be of a nature that would allow the activity to be immediately delayed or interrupted should obstetric work arise. Under these circumstances, the duty anaesthetist should be able to delegate care of their non-obstetric patient immediately to be able to respond to a request for care of obstetric patients. Therefore, for example, they would not simultaneously be able to be a member of the on-call resuscitation team. If the duty anaesthetist covers general theatres, there should be another anaesthetist ready to take over immediately should they be needed to care for obstetric patients.
Adequate time for formal handover between shifts should be built into the timetable.
A structured tool should be considered to facilitate handover.24
The duty anaesthetist should participate in delivery suite ward rounds.25
The lead obstetric anaesthetist
Every obstetric unit should have a designated lead anaesthetist (see glossary) with specific programmed activities allocated for this role.
The lead obstetric anaesthetist should be responsible for the overall delivery of the service, which includes ensuring that evidence-based guidelines and protocols are in use and are up to date; monitoring staff training, workforce planning, and service risk management; and ensuring that national specifications are met, and auditing the service against these agreed standards, including anaesthetic complication rates.
The lead obstetric anaesthetist should ensure representation of the anaesthetic department at multidisciplinary meetings for service planning, e.g. labour ward forum.23
The lead obstetric anaesthetist should ensure that there are ongoing quality improvement projects in place to maintain and improve the care in their units.26
As a basic minimum for any obstetric unit, a consultant anaesthetist should be allocated to ensure consultant cover for the full daytime working week (that is, ensuring that mon-fri, morning and afternoon sessions are staffed).23 This is to provide urgent and emergency care, not to undertake elective work.
In busier units, increased levels of consultant cover should be considered, reflecting the level of consultant obstetrician staffing in the unit.27 This may involve extending the working day to include consultant presence into the evening session and/or increasing consultant numbers.
Additional consultant programmed activities should be allocated for:
- elective caesarean deliveries
- antenatal anaesthetic clinics (or to review referrals if no formal clinic is in place).23
In units where trainee anaesthetists work a full or partial shift system, and/or rotate through the department every three months (or more frequently), provision of additional consultant programmed activities should be considered, to allow training and supervision into the evening.28
There should be a named consultant anaesthetist responsible for every elective caesarean delivery operating list. This consultant should be immediately available.
Consultant support should be available at all times with a response time of not more than half an hour to attend the delivery suite, and maternity operating theatre. The supervising consultant should not therefore be responsible for two or more geographically separate obstetric units.
Staff working in the maternity unit should know how to contact the anaesthetic consultant; the name(s) of the consultant(s) covering the delivery suite should be clearly displayed and easily visible to all staff, and contact numbers readily available.
The anaesthetist caring for the woman should not be responsible for neonatal resuscitation and the care of the newborn baby.20
Women requiring anaesthesia in the peripartum period should have at least the same standards of perioperative care as for any surgical patient.29
The anaesthetist should have a competent trained assistant immediately available for the duration of any anaesthetic intervention and this practitioner should not have any other duties.29
Anaesthetic assistants who cover obstetrics should demonstrate additional knowledge and skills specific to the care of pregnant women.30
Anaesthetists and anaesthetic assistants working without direct supervision in obstetric theatres and on the delivery suite should be familiar with the environment and working practices of that unit, and work there on a frequent basis to maintain that familiarity.
Post-anaesthetic recovery staff
All theatre and post-anaesthetic recovery staff looking after the obstetric population should be familiar with the area for recovery of obstetric patients and be experienced in the use of the different early warning scoring systems for obstetric patients. They should have been trained to the same standard as for all recovery nurses, have maintained these skills through regular work on the theatre recovery unit, and have undergone a supernumerary preceptorship in this environment before undertaking unsupervised work.31,34
Other members of the team
An adult resuscitation team trained in resuscitation of the pregnant patient should be immediately available.35
There should be secretarial support for the department of anaesthesia, including the obstetric anaesthetic service.
Provision should be made to ensure access to appropriate healthcare professionals to support women who require their services, such as clinical pharmacists, dietitians, outreach nurses and physiotherapists.16
Locum anaesthetists should be assessed to ensure their competence prior to undertaking work without direct supervision.23
2. Equipment, services and facilities
Blood gas analysis (with the facility to measure serum lactate and the facility for rapid estimation of haemoglobin and blood sugar) should be available on the delivery suite.
Delivery suite rooms should be equipped with monitoring equipment for the measurement of non-invasive blood pressure, oxygen saturation and heart rate.
Delivery suite rooms should have oxygen, suction equipment and access to resuscitation equipment. Equipment should be checked daily in accordance with the Association of Anaesthetists published guidelines.36
The standard of monitoring in the obstetric theatre should allow the conduct of safe anaesthesia for surgery as detailed by the Association of Anaesthetists standards of monitoring.39
A fluid warmer device allowing rapid transfusion of blood products and intravenous fluids should be available.41
A rapid infusion device should be available for the management of major haemorrhage.40
In tertiary units, with a high risk population, it is recommended that there should be equipment to enable near patient estimation of coagulation such as thromboelastography (TEG) or thromboelastometry.54
Cell salvage may be considered for women who refuse blood products or where massive obstetric haemorrhage (MOH) is anticipated but it should not be used routinely for caesarean delivery. Women should be informed of the risks and benefits of its use and staff who operate this equipment should receive training in how to operate it, and use it frequently to maintain their skills.
Devices, such as forced air warmers, to prevent and/or treat hypothermia should be available.43
A difficult intubation trolley with a variety of laryngoscopes, including video laryngoscopes; tracheal tubes (size 7 and smaller); laryngeal masks, including second generation supraglottic airway devices; and other aids for airway management, should be available in theatre. The difficult intubation trolley should have a standard layout which is identical to trolleys in other parts of the hospital so that users will find the same equipment and layout in all sites.
Patient controlled analgesia (PCA) equipment should be available for postoperative pain relief, and staff operating it should be trained in its use and how to look after women with PCA.46
The maximum weight that the operating table can support should be known, and alternative provision made for women who exceed this. It is recommended that the obstetric operating table should be able to safely support a weight of at least 160 Kg in all positions.
Equipment to facilitate the care of morbidly obese women (including specialised electrically operated beds, and positioning aids such as commercially produced ramping pillows, weighing scales, sliding sheets, and hover mattresses or hoists) should be readily available and staff should receive training on how to use the specialised equipment.47
Ultrasound equipment should be available for use by trained staff for transversus abdominis plane (TAP) blocks, central neuraxial blockade, placing lines and transthoracic echocardiography. Other tasks, such as airway and gastric volume assessment, may also benefit from the availability of ultrasound.50
Synchronised clocks should be present in all delivery rooms and theatres to facilitate the accurate recording of events and to comply with medicolegal requirements.51
Resuscitation equipment, including an automated defibrillator, should be available on the delivery suite and should be checked regularly.52 A perimortem caesarean section pack containing a scalpel, surgical gloves and cord clamp should be available on all resuscitation trolleys in the Maternity Unit and areas admitting pregnant women e.g. emergency departments.53 A range of various sizes of tracheal tubes of no >7 mm internal diameter should also be kept on the resuscitation trolleys.4
There should be arrangements or standing orders in place for agreed preoperative laboratory investigations. There should be a standard prescription or a local Patient Group Directive for preoperative antacid prophylaxis.
Haematology and biochemistry services to provide analysis of blood and other body fluids should be available 24/7.
O negative blood should be immediately available, and ideally stored on the delivery suite.
There should be rapid availability of radiology services.
In tertiary referral centres, there should be 24-hour access to interventional radiology services.52
Echocardiography should be available at all times in units that routinely deal with cardiac patients.6
There should be access to a clinical pharmacist of an appropriate competency level and with appropriate experience in obstetrics, to advise on day-to-day medication or prescribing issues in the obstetric population, and to provide input in local policies and procedures pertaining to any aspects of medicines management.59
Sterile prefilled syringes or bags of low dose local anaesthetic combined with opioid solutions for regional analgesia should be available.
Prefilled syringes of commonly used emergency drugs, e.g. suxamethonium and phenylephrine, should be used where available.60
Local anaesthetic solutions intended for epidural infusion should be stored separately from intravenous infusion solutions to minimise the risk of accidental intravenous administration of such drugs.61
Medication for rare but life threatening anaesthetic emergencies, in particular Intralipid, sugammadex and dantrolene, should be immediately available to the delivery suite, and their location should be clearly identified. There should be a clear local agreement on the responsibility for maintenance of these emergency medicines, i.e. regular checks of stock levels, integrity, and expiry dates.
Physiotherapy services should be available 24/7 for patients requiring high dependency care.
There should be easy and safe access to the delivery suite from the main hospital at all times.
An emergency call system should be provided.
There should be at least one fully equipped obstetric theatre within the delivery suite, or immediately adjacent to it. Appropriately trained staff should be available to allow emergency operative deliveries to be undertaken without delay.20 The number of operating theatres available for obstetric procedures will depend on the number of deliveries and the operative risk profile of the women delivering in the unit.
There should be medication storage facilities within maternity theatres which provide timely access to medicines when clinically required, while maintaining integrity of the medicinal product and allowing the organisation to comply with safe and secure storage of medicines regulations.59,62
Adequate recovery room facilities, including the ability to monitor blood pressure, ECG, oxygen saturation, end-tidal carbon dioxide and temperature, should be available within the delivery suite theatre complex.39
Anaesthetic machines, monitoring and infusion equipment and near patient testing devices should be maintained, repaired and calibrated by medical physics technicians.
All units should have facilities, equipment and appropriately trained staff to provide care for acutely ill obstetric patients. If this is unavailable, women should be transferred to the general critical care area in the same hospital with staff trained to provide care to obstetric patients.16
All patients should be able to access level 3 critical care if required; units without such provision on site should have an arrangement with a nominated level 3 critical care unit and an agreed policy for the stabilisation and safe transfer of patients to this unit when required.16,52 Portable monitoring with the facility for invasive monitoring should be available to facilitate safe transfer of obstetric patients to the ICU.63
An anaesthetic office, within five minutes from the delivery suite, should be available to the duty anaesthetic team. The room should have a computer with intra/internet access for access to specialist reference material and local multidisciplinary evidence based guidelines and policies. The office space, facilities and furniture should comply with the standards recommended by the Association of Anaesthetists guidelines.64 This office could also be used to allow teaching, assessment and appraisal.64
A communal rest room in the delivery suite should be provided to enable staff of all specialties to meet.
A seminar room should be accessible for training, teaching and multidisciplinary meetings.
All hospitals should ensure the availability of areas that allow those doctors working night shifts to take rest breaks essential for the reduction of fatigue and improve safety.25 These areas should not be used by more than one person at a time and allow the doctor to fully recline.
Standards of accommodation for doctors in training should be adhered to.25 Where a consultant is required to be resident, on-call accommodation should be provided.
Hotel services should provide suitable on-call facilities, including housekeeping services for resident and non-resident anaesthetic staff. Refreshments should be available 24/7.
All obstetric departments should provide and regularly update multidisciplinary guidelines. A comprehensive list of recommended guidelines can be found in the Obstetric Anaesthetists' Association (OAA)/Association of Anaesthetists guidelines for obstetric anaesthesia services.
Guidelines for the management of pregnant women receiving anticoagulation should be available.65
3. Areas of special requirement
Care for the acutely ill obstetric patient
NICE guidance on the recognition of and response to acute illness in adults in hospitals should be implemented.61
All units should be able to escalate care to an appropriate level, and critical care support should be provided as soon as required, regardless of location.54
When midwives provide a level of care beyond their routine scope of practice, they should be appropriately trained.
There should be a named consultant anaesthetist and obstetrician responsible 24/7 for all women requiring a higher level of care.16
Women requiring critical care in a non-obstetric facility should be reviewed daily by a maternity team including an anaesthetist. 4
Care for the obese woman
The incidence of obesity is rising in the obstetric population. Obesity is associated with increased incidence of both obstetric and medical complications.70
The duty anaesthetist should be informed as soon as a woman with a BMI above a locally agreed threshold is admitted.
There should be appropriate equipment to care for obese women.73
Care for women under the age of eighteen
The following recommendations apply to units that admit young women and girls under the age of eighteen years for obstetric services.
There should be a multidisciplinary protocol governing care of these patients that includes: consent, the environment in which these patients are cared for, and the staff responsible for caring for these young people.
At least one anaesthetist in each anaesthetic department, not necessarily an obstetric anaesthetist, should take the lead in safeguarding/child protection83 and undertake training and maintain core level 3 competencies. The lead anaesthetist for safeguarding/child protection should liaise with their multidisciplinary counterparts within the obstetric unit.
Care for women requiring specialist services
There should be policies defining how women are referred to and access specialist or tertiary services (e.g. neurosurgery, acute stroke services).4
4. Training and education
All anaesthetists involved in the care of pregnant women should be competent to deliver high quality, safe care that takes into account the physiological changes in and other requirements of pregnant women.84
There should be a nominated consultant responsible for training in obstetric anaesthesia, with adequate programmed activities allocated for these responsibilities.52
Elective caesarean deliveries should be utilised for training purposes.85
There should be induction programmes for all new members of staff, including locums. Induction for a locum doctor should include familiarisation with the layout of the labour ward, the location of emergency equipment and drugs (e.g. MOH trolley/intralipid/dantrolene), access to guidelines and protocols, information on how to summon support/assistance, and assurance that the locum is capable of using the equipment in that obstetric unit. All inductions should be documented.
Anaesthetists with a job plan that includes obstetric anaesthesia must demonstrate ongoing continuing education in obstetric anaesthesia, and continuing professional development as needed for this aspect of their work.101 Hospitals have a responsibility to enable this with local teaching where appropriate, and by facilitating access to other education and training.93,102,103
Any non-trainee anaesthetist who undertakes anaesthetic duties in the labour ward should have been assessed as competent to perform these duties in accordance with OAA and RCoA guidelines.29,52,86 Such a doctor should work regularly in the labour ward but should also regularly undertake non-obstetric anaesthetic work to ensure maintenance of a broad range of anaesthetic skills.
All staff working on the delivery suite should have annual resuscitation training, including the specific challenges of pregnant women.104
Anaesthetists should contribute to the education and updating of midwives, anaesthetic assistants and obstetricians.
5. Organisation and administration
A system should be in place to ensure that women requiring antenatal referral to an anaesthetist are seen and assessed by an anaesthetist, normally a consultant, within a suitable time frame and preferably in early pregnancy. Ideally, this should be in the form of multidisciplinary team management of these high risk women.
An anaesthetist should be included in the multidisciplinary team (MDT) antenatal planning of management for women with complex medical needs.4
All women requiring caesarean section should, except in extreme emergency, be visited and assessed by an anaesthetist before arrival in the operating theatre. This should be timed to allow women sufficient time to weigh up the information they have been given, in order to give informed consent for anaesthesia.
There should be a local guideline on the monitoring of women after regional anaesthesia and the management of post anaesthetic neurological complications.106
All women who have received regional analgesia/anaesthesia or general anaesthesia for labour and delivery should be reviewed following delivery. Locally agreed discharge criteria should be met before women go home with written information provided.107
Women must be assumed to have capacity unless there is evidence to the contrary, as per the Mental Capacity Act.108
There should be documentation of any discussions informing consent for any procedures undertaken by the anaesthetist.108
Written consent should be obtained for epidural blood patching.108
Neuraxial and opioid analgesia
Obstetric units should be able to provide neuraxial analgesia on request. Smaller units may be unable to provide a 24-hour service; women booking at such units should be made aware that neuraxial analgesia may not always be available.52
Midwifery care of a woman receiving neuraxial analgesia in labour should comply with local guidelines that have been agreed with the anaesthetic department. Local guidelines should include required competencies, maintenance of those competencies and frequency of training. If the level of midwifery staffing is considered inadequate, neuraxial analgesia block should not be provided.
Units should have local guidelines on the recognition and management of complications of neuraxial analgesia that include training on the recognition of complications and access to appropriate imaging facilities when neurological injury is suspected.
Neuraxial analgesia should not be used in labour unless the obstetric team is immediately available.
There should be a locally agreed neuraxial analgesia record and a protocol for the prescription and administration of drugs.
When the anaesthetist is informed of a request for neuraxial analgesia (and the circumstances would be suitable for this type of analgesia) the anaesthetist should attend within 30 minutes of being informed. Only in exceptional circumstances should this period be longer, and in all cases attendance should be within one hour. This should be the subject of regular audits.26
When remifentanil PCA is provided as an alternative to neuraxial analgesia, there should be local multidisciplinary guidelines.110
Midwives caring for women receiving remifentanil PCA should be trained specifically in the use of the technique, and stay with the woman continuously without any break in observation. Remifentanil PCA should only be provided in units where it is frequently used. Rapid reversal of respiratory depression/arrest and airway resuscitation equipment should be immediately available.
Emergency caesarean delivery
There should be a clear line of communication between the duty anaesthetist, theatre staff and anaesthetic assistant once a decision is made to undertake an emergency caesarean delivery.
The anaesthetist should be informed about the category of urgency of caesarean delivery at the earliest opportunity.111
A World Health Organization (WHO) checklist adapted for maternity should be used in theatre.
Before induction of general anaesthesia, there should be a multidisciplinary discussion about whether to wake the woman or to continue with anaesthesia in the event of failed tracheal intubation.113
There should be clear arrangements in contingency plans and an escalation policy for use should two emergencies occur simultaneously, including whom to call.
Hospitals should have approved documentation defining safe staffing levels for anaesthetists and anaesthetic assistants, including contingency arrangements for managing staffing shortfalls, and annual reviews of compliance with these should be performed.
The multidisciplinary team
Care of the pregnant woman is delivered by teams rather than individuals. Effective teamwork has been shown to increase safety, while poor teamwork has the opposite effect.68,93 It is, therefore, important that obstetric anaesthetists develop effective leadership and team membership skills, with good working relationships and lines of communication with all other professionals, including those whose care may be needed for difficult cases. This includes midwives, obstetricians and neonatologists, as well as professionals from other disciplines such as intensive care, obstetric physicians, neurology, cardiology, haematology, radiology, general practitioners and other physicians and surgeons.
Units with high numbers of caesarean delivery should have elective caesarean delivery lists to minimise disruption due to emergency work. 84, Any elective caesarean delivery list should have dedicated obstetric, anaesthetic and theatre staff.
If any major restructuring of the provision of local maternity services are planned, the lead obstetric anaesthetist should be involved in that process.23
Hospitals should have systems in place to facilitate multidisciplinary morbidity and mortality meetings.119
There should be systematic measures in place to respond to serious incidents. These measures should protect patients and ensure that robust investigations are carried out by trained safety leads. When an incident occurs, it should be reported to all relevant bodies within and beyond the hospital. A system of peer review or external evaluation of serious incident reports should be in place.120,121
An anaesthetist should be involved in all case reviews where the case includes anaesthetic input.
6. Financial considerations
There is a paucity of evidence regarding the financial implications of many of the recommendations we make here. Many of them are not new however and, although we do not have data about the compliance of every unit with previous versions of these guidelines, the vast majority of units will already adhere to most of the standards outlined here. Many of the recommendations represent a financial impact on workforce and time allowance and this should be dealt with in robust job planning and specification in each anaesthetic department and, in the case of hospital managers, at trust or board level.
Where we have made recommendations about specific equipment, this may have implications for capital and operational expenditure in terms of acquisition of the equipment and its ongoing use and maintenance. Where these recommendations are made, it is based on evidence that there is benefit to patients in terms of outcome and/or improved safety, or that it offers a cost-effective alternative to other treatment options available. Local business cases and action plans may need to be developed. The cost of implementing any of these evidence-based recommendations should always be considered in relation to the financial risks of providing substandard care. Apart from the human costs of this, litigation in maternity services is an expensive issue.
Any service implications will have to be considered against the background of the need for all NHS trusts in England and Wales to reduce expenditure, and in the context of the proposed changes to the budgetary structure of maternity services.122 We recognise that staff in some units, particularly those with smaller delivery rates, may feel it is burdensome to implement some of these service specifications. It is not the purpose of this guidance to dictate how these recommendations are met – that is to be decided locally. Individual trusts/boards and their executives will need to consider the ongoing viability of any maternity unit that continues to fail to meet these standards. The amalgamation or formalised intertrust/board partnerships of smaller consultant-led units, for example, which are an effort to pool resources more efficiently, may require consideration if service provision consistently falls short of the expected standards.
7. Research, audit and quality improvement
The lead obstetric anaesthetist should audit and monitor the duty anaesthetist workload to ensure that there is sufficient provision for the busyness of the unit.
There should be regular audits of the quality of clinical governance, with particular attention being paid to provision and updating of local guidelines, reviews of adverse events, and record keeping.23
There should be a regular audit of delays to elective caesarean deliveries.52
The use of an obstetric appropriate WHO style checklist before all surgical obstetric interventions should be the subject of regular audit and observational study.112
All cases of maternal death, significant permanent neurological deficit, failed intubation or awareness during general anaesthesia should undergo case review, with learning from this shared locally and/or nationally.26
Provision of supernumerary training sessions for non-specialist anaesthetists expected to provide out-of-hours or emergency care on the maternity unit should be the subject of review.
In units providing a programme of enhanced recovery from caesarean delivery, there should be regular audits of readmission rates for these women.126
As well as the specific topics detailed above, a regular audit programme should encompass national audit recipes and standards.26
Care should be taken to ensure that all audit, standards and guidelines documents carry clear definitions of terms such as ‘neuraxial analgesia rate’.17
Research in obstetric anaesthesia and analgesia should be encouraged. Research must follow strict ethical standards as stated by the General Medical Council (GMC).127
8. Implementation support
The Anaesthesia Clinical Services Accreditation (ACSA) scheme, run by the RCoA, aims to provide support for departments of anaesthesia to implement the recommendations contained in the GPAS chapters. The scheme provides a set of standards, and asks departments of anaesthesia to benchmark themselves against these using a self-assessment form available on the RCoA website. Every standard in ACSA is based on recommendation(s) contained in GPAS. The ACSA standards are reviewed annually and republished approximately four months after GPAS review and republication to ensure that they reflect current GPAS recommendations. ACSA standards include links to the relevant GPAS recommendations so that departments can refer to them while working through their gap analyses.
Departments of anaesthesia can subscribe to the ACSA process on payment of an appropriate fee. Once subscribed, they are provided with a ‘College guide’ (a member of the RCoA working group that oversees the process), or an experienced reviewer to assist them with identifying actions required to meet the standards. Departments must demonstrate adherence to all ‘priority one’ standards listed in the standards document to receive accreditation from the RCoA. This is confirmed during a visit to the department by a group of four ACSA reviewers (two clinical reviewers, a lay reviewer and an administrator), who submit a report back to the ACSA committee.
The ACSA committee has committed to building a ‘good practice library’, which will be used to collect and share documentation such as policies and checklists, as well as case studies of how departments have overcome barriers to implementation of the standards, or have implemented the standards in innovative ways.
One of the outcomes of the ACSA process is to test the standards (and by doing so to test the GPAS recommendations) to ensure that they can be implemented by departments of anaesthesia and to consider any difficulties that may result from implementation. The ACSA committee has committed to measuring and reporting feedback of this type from departments engaging in the scheme back to the CDGs updating the guidance via the GPAS technical team.
9. Patient communication and information
Information should be made available to purchasers and to women in the early antenatal period about availability of neuraxial analgesia and anaesthetic services in their chosen location for delivery.52
Every unit should provide, in early pregnancy, advice about pain relief and anaesthesia during labour and delivery. An anaesthetist should be involved in preparing this information and approve the final version.108
Information must be made available to women in the antenatal period about possible deviations from normal delivery and of emergencies that might arise in the peripartum period, in anticipation of constraints imposed by time and circumstances in the event of such situations arising.108,128,129,130
Units should consider local demographics, such as the prevalence of particular languages, when designing information or commissioning interpreting services.
Hospitals should ensure that the mother’s need for information in other languages should be assessed and recorded during antenatal care so that interpreting services can be planned for.
Interpreting services should be made available for non-English speaking women, with particular attention paid to how quickly such services can be mobilised and their availability out of hours.
Face to face interpreting services should be considered as most suitable, given the practical requirements for women in labour. However, telephone based services may be able to serve a greater number of languages and be more quickly mobilised, particularly out of hours.
Women who refuse transfusion of blood or blood products, whether because of adherence to the Jehovah’s Witness faith or for other reasons, should be identified early in the antenatal period. They should meet with an anaesthetist to discuss their specific restrictions, and should receive information about the potential risks associated with their decision.135,136 Their decision should be documented as part of the informed consent process. Such conversations should be conducted with appropriate privacy to avoid the risk of coercion.
Women with potential capacity to consent issues should be identified early in the antenatal period, and arrangements made to both maximise their competency and to ensure that they are adequately represented and advocated for, in keeping with current legislation.137
All explanations given to women should be clearly documented in their records.
If complaints are made about aspects of care, a consultant anaesthetist should review and assess the patient’s complaint, discussing her concerns and examining her where appropriate. This should be documented. Referral for further investigations may be required.
Complaints should be handled according to local policies.
The lead obstetric anaesthetist should be made aware of all complaints.
Busy units – The busyness of a unit cannot be defined solely by the number of births. For the anaesthetic department, the number of anaesthetic interventions, (defined as the number of regional anaesthetics e.g. epidural, spinal, combined spinal-epidural, where the indication was 'labour', the number of caesarean sections, instrumental deliveries and any other procedure performed in the operating theatre, the number of critically ill women requiring anaesthetic input and the number of women seen in the anaesthetic antenatal clinics) may provide the best proxy measure to judge the busyness of the unit.17 In this document, the term 'busier units' is used to denote those units that, due to the number of anaesthetic interventions and/or other local factors, require higher levels of resources in order to deliver the necessary anaesthetic service.
Duty anaesthetist – The term ‘duty anaesthetist’ is used here to denote the anaesthetist who is the doctor immediately responsible for the provision of obstetric anaesthetic services during the duty period.
Lead anaesthetist – Staff grade, associate specialist and specialty (SAS) anaesthetists undertaking lead roles should be autonomously practicing doctors who have competence, experience and communication skills in the specialist area equivalent to consultant colleagues. They should usually have experience in teaching and education relevant to the role and they should participate in Quality Improvement and CPD activities. Individuals should be fully supported by their Clinical Director and be provided with adequate time and resources to allow them to effectively undertake the lead role.
Immediately – Unless otherwise defined, ‘immediately’ means within five minutes.
Obstetric unit – an NHS clinical location in which care is provided by a team, with obstetricians taking primary professional responsibility for women at high risk of complications during labour and birth. Midwives offer care to all women in an obstetric unit, whether or not they are considered at high or low risk, and take primary responsibility for women with straightforward pregnancies during labour and birth. Diagnostic and treatment medical services, including obstetric, neonatal and anaesthetic care, are available on site 24 hours a day.18
Obstetrician-led care – Care in labour where the obstetrician is responsible for the woman’s care. This should only be provided in an obstetric-led unit in a hospital. Much of the woman’s care will still be provided by a midwife.19
Obstetric team – The term ‘obstetric team’ is used here to denote all the members of the multidisciplinary team that work in the maternity unit20
Supervising consultant – The term ‘supervising consultant’ is used here to denote the consultant anaesthetist with responsibility for the delivery of obstetric anaesthetic services during the duty period.
Supervision – Trainees should be supervised in accordance with the curriculum.88The diverse nature of SAS posts means that the standards of education, training and experience that can be expected from post holders can vary quite widely. The degree of supervision a doctor requires should be agreed via a robust, local governance process and follow the RCoA guidance on ‘Supervision of SAS and other non-consultant anaesthetists’.21 More experienced SAS doctors may have the expertise and ability to take responsibility for patients themselves, without consultant supervision, under certain circumstances.
