Diabetes in pregnancy

About

What is covered

This NICE Pathway covers managing diabetes and its complications in women who are planning pregnancy or are already pregnant. It aims to improve the diagnosis of gestational diabetes and help women with diabetes to self-manage their blood glucose levels before and during pregnancy.

Blood glucose and plasma glucose

'Blood glucose' is the more commonly used term. However, a lot of the evidence this guideline is based on uses 'plasma' rather than 'blood' glucose, and patient-held glucose meters and monitoring systems are calibrated to plasma glucose equivalents. Because of this, in this NICE Pathway we use the term 'blood glucose', except when referring to specific concentration values.

Updates

Updates to this NICE Pathway

Person-centred care

People have the right to be involved in discussions and make informed decisions about their care, as described in your care.
Making decisions using NICE guidelines explains how we use words to show the strength (or certainty) of our recommendations, and has information about prescribing medicines (including off label use), professional guidelines, standards and laws (including on consent and mental capacity), and safeguarding.

Your responsibility

Guidelines

The recommendations in this guideline represent the view of NICE, arrived at after careful consideration of the evidence available. When exercising their judgement, professionals and practitioners are expected to take this guideline fully into account, alongside the individual needs, preferences and values of their patients or the people using their service. It is not mandatory to apply the recommendations, and the guideline does not override the responsibility to make decisions appropriate to the circumstances of the individual, in consultation with them and their families and carers or guardian.
Local commissioners and providers of healthcare have a responsibility to enable the guideline to be applied when individual professionals and people using services wish to use it. They should do so in the context of local and national priorities for funding and developing services, and in light of their duties to have due regard to the need to eliminate unlawful discrimination, to advance equality of opportunity and to reduce health inequalities. Nothing in this guideline should be interpreted in a way that would be inconsistent with complying with those duties.
Commissioners and providers have a responsibility to promote an environmentally sustainable health and care system and should assess and reduce the environmental impact of implementing NICE recommendations wherever possible.

Quality statements

High-dose folic acid

This quality statement is taken from the diabetes in pregnancy quality standard. The quality standard defines clinical best practice for diabetes in pregnancy and should be read in full.

Quality statement

Women with diabetes planning a pregnancy are prescribed 5 mg/day folic acid from at least 3 months before conception.

Rationale

High-dose folic acid supplements (5 mg/day) should be prescribed for women with diabetes who are planning a pregnancy from at least 3 months before conception until 12 weeks of gestation. This is because these women are at greater risk of having a baby with a neural tube defect. The benefits of high-dose folic acid supplementation should be discussed with the woman during preconception counselling as part of her preparation for pregnancy.

Quality measures

Structure
Evidence of local arrangements and written clinical protocols to ensure that women with diabetes planning a pregnancy are prescribed 5 mg/day folic acid from at least 3 months before conception.
Data source: NHS Digital National Pregnancy in Diabetes Audit and local data collection.
Process
a) Proportion of pregnant women with type 1 diabetes prescribed 5 mg/day folic acid from at least 3 months before conception.

What the quality statement means for different audiences

Service providers (in primary and secondary care) ensure that they have systems and processes in place so that women with diabetes who are planning a pregnancy are prescribed 5 mg/day folic acid from at least 3 months before conception.
Healthcare professionals (GPs, community midwives and healthcare professionals in joint diabetes and antenatal care teams) ensure that they prescribe 5 mg/day folic acid for women with diabetes who are planning a pregnancy, from at least 3 months before conception. Healthcare professionals also ensure that they advise women with diabetes who are planning a pregnancy about the benefits of taking high-dose folic acid as part of preconception counselling.
Commissioners (NHS England area teams and clinical commissioning groups) ensure that they commission pre-pregnancy services in which 5 mg/day folic acid is prescribed for women with diabetes who are planning a pregnancy, from at least 3 months before conception.
Women with diabetes who are planning a pregnancy are given a prescription for high-dose folic acid (one 5 mg tablet a day) for at least 3 months before they get pregnant and for the first 12 weeks of pregnancy. This helps to lower the chances of the baby having a condition called a neural tube defect (for example, spina bifida).

First contact with joint diabetes and antenatal care team

This quality statement is taken from the diabetes in pregnancy quality standard. The quality standard defines clinical best practice for diabetes in pregnancy and should be read in full.

Quality statement

Women with pre-existing diabetes are seen by members of the joint diabetes and antenatal care team within 1 week of their pregnancy being confirmed.

Rationale

Women with diabetes who become pregnant need extra care in addition to routine antenatal care. Members of the joint diabetes and antenatal care team are able to ensure that specialist care is delivered to minimise adverse pregnancy outcomes. Immediate access to the joint diabetes and antenatal care team within 1 week of her pregnancy being confirmed will help to ensure that a woman’s diabetes is controlled during early pregnancy, when there in an increased risk of fetal loss and anomalies. It will also help to ensure that the woman’s care is planned appropriately throughout her pregnancy.

Measuring HbA1c levels at booking appointment

This quality statement is taken from the diabetes in pregnancy quality standard. The quality standard defines clinical best practice for diabetes in pregnancy and should be read in full.

Quality statement

Pregnant women with pre-existing diabetes have their HbA1c levels measured at their booking appointment.

Rationale

Measuring a woman’s HbA1c levels can be used to determine the level of risk for her pregnancy. Women who had diabetes before they became pregnant should have their HbA1c levels measured during early pregnancy to identify the risk of potential adverse pregnancy outcomes and to ensure that any identified risks are managed.

Booking appointment
A woman with diabetes will usually have a booking appointment with the joint diabetes and antenatal care team by 10 weeks of pregnancy. In some cases this appointment may take place earlier in the pregnancy. [NICE’s guideline on diabetes in pregnancy and expert opinion]

Equality and diversity considerations

Pregnant women with diabetes and complex social needs may be less likely to access or maintain contact with antenatal care services, and may present to a service later than 10 weeks. Services should give special consideration to these groups of women and ensure that they have their HbA1c levels measured at the earliest opportunity.  

Referral for retinal assessment

This quality statement is taken from the diabetes in pregnancy quality standard. The quality standard defines clinical best practice for diabetes in pregnancy and should be read in full.

Quality statement

Pregnant women with pre-existing diabetes are referred at their booking appointment for retinal assessment.

Rationale

Pregnant women with pre-existing diabetes can have an increased risk of progression of diabetic retinopathy. Women should therefore be screened for diabetic retinopathy regularly during pregnancy. Early assessment ensures that treatment can start as soon as possible, and can act as a baseline to observe any further deterioration. A referral for retinal assessment should be offered at the booking appointment unless the woman has had an assessment in the last 3 months.

Quality statement

Women diagnosed with gestational diabetes are seen by members of the joint diabetes and antenatal care team within 1 week of diagnosis.

Rationale

Women diagnosed with gestational diabetes should have specialist advice and treatment in a timely manner, and should be reviewed by members of the joint diabetes and antenatal care team within 1 week of being diagnosed.

Self-monitoring of blood glucose levels during pregnancy

This quality statement is taken from the diabetes in pregnancy quality standard. The quality standard defines clinical best practice for diabetes in pregnancy and should be read in full.

Quality statement

Pregnant women with diabetes are supported to self-monitor their blood glucose levels.

Rationale

Women with diabetes need to be able to self-monitor their blood glucose during pregnancy. Some women with type 2 diabetes and all women with gestational diabetes will not have been monitoring their blood glucose levels at all before pregnancy and will start doing so. For women with type 1 diabetes, and some women with type 2 diabetes, frequency of monitoring will increase from 4 times a day to up to 10 times per day. More frequent monitoring will help women to maintain good blood glucose control throughout pregnancy. This in turn will reduce the risk of adverse outcomes, such as a baby that is large for gestational age, trauma during birth, neonatal hypoglycaemia and perinatal death. The likelihood of induction of labour and caesarean section should also be lower. Support should be provided to ensure that women have access to appropriate blood glucose meters and are prescribed enough testing strips, and know how to use them.

Equality and diversity considerations

When advising women to start or increase the frequency of blood glucose monitoring, take into account that some women may be anxious and feel pressure to adjust and overly regulate their blood glucose levels.

Annual HbA1c testing after gestational diabetes

This quality statement is taken from the diabetes in pregnancy quality standard. The quality standard defines clinical best practice for diabetes in pregnancy and should be read in full.

Quality statement

Women who have had gestational diabetes have an annual HbA1c test.

Rationale

Women who have had gestational diabetes are at increased risk of getting it again in future pregnancies. They are also at higher risk of type 2 diabetes: if they are not diagnosed with type 2 diabetes in the immediate postnatal period, they are still at high risk of developing it in the future. Early detection of type 2 diabetes by annual HbA1c testing in primary care can delay disease progression and reduce the risk of complications. Annual testing can also reduce the risk of uncontrolled or undetected diabetes in future pregnancies.

Definitions

NICE full guideline on antenatal care for uncomplicated pregnancies acknowledges that the ‘booking appointment’ needs to be earlier in pregnancy (ideally by 10 weeks) than may have traditionally occurred.
NICE’s guideline on antenatal care for uncomplicated pregnancies recommends that the schedule of antenatal appointments is determined by the woman’s needs. For a woman who is nulliparous with an uncomplicated pregnancy, a schedule of 10 appointments should be adequate. For a woman who is parous with an uncomplicated pregnancy, a schedule of 7 appointments should be adequate.
Follow-up after a missed appointment may be undertaken by the maternity service or other community-based service the woman is in contact with, such as a children’s centre, addiction service or GP. Follow-up should be via a method of contact that is appropriate to the woman, which may include:
  • text message
  • letter
  • telephone
  • community or home visit.

Equality and diversity considerations

Pregnant women include women with complex social needs who may be less likely to access or maintain contact with antenatal care services. Examples of women with complex social needs include, but are not limited to, women who:
  • have a history of substance misuse (alcohol and/or drugs)
  • have recently arrived as a migrant, asylum seeker or refugee
  • have difficulty speaking or understanding English
  • are aged under 20
  • have experienced domestic abuse
  • are living in poverty
  • are homeless.
It is therefore appropriate that localities give special consideration to these groups of women within the measures. NICE’s guideline on pregnancy and complex social factors has recommendations about how to make antenatal care accessible to pregnant women with complex social needs and how to encourage women to maintain ongoing contact with maternity services.

Note that women should be able to make an informed choice about whether to accept or decline each test, and notes should include a record of any tests offered and declined as well as the results of tests accepted.

Equality and diversity considerations

Hand-held maternity notes and the information within them should be accessible to all women, including women who do not speak or read English and those with additional needs such as physical, sensory or learning disabilities.
Women should be able to choose whether to have all the results of their antenatal tests documented in their hand-held maternity notes. This may be particularly important when information is sensitive (for example, positive screening results for HIV, hepatitis B virus and syphilis). Where a woman declines to have antenatal test results documented in her hand-held notes, the results should instead be recorded within other medical notes.

Source guidance

Definitions

An appropriately trained person can demonstrate expertise and competencies in weight management in pregnancy, including providing advice about nutrition and/or physical activity. This may include obstetricians, GPs, midwives, health visitors, nurses, dietitians, midwifery assistants, support workers and those working in weight management programmes (commercial or voluntary).

Equality and diversity considerations

The body mass index threshold may need adapting for different groups of pregnant women (for example, women from certain ethnic groups). See NICE’s guideline on BMI: preventing ill health and premature death in black, Asian and other minority ethnic groups. A body mass index measure is considered unsuitable for use with those under 18.

Definitions

Advice on smoking cessation should be first provided at the booking appointment and when appropriate throughout the period of antenatal care. The midwife may provide the pregnant woman with information (in a variety of formats, for example a leaflet) about the risks to the unborn child of smoking when pregnant and the hazards of exposure to second-hand smoke for both mother and baby.
Women who smoke or have recently quit smoking should be referred to an evidence-based stop smoking service if:
  • they say they smoke, or
  • they have a carbon monoxide (CO) reading of 7 ppm or above, or
  • they say they have quit smoking in the past 2 weeks, or
  • they say they are a light or infrequent smoker but register a low CO reading (for example, 3 ppm).
Evidence-based stop smoking services are local services providing accessible, evidence-based and cost-effective support to people who want to stop smoking. The professionals involved may include midwives who have been specially trained to help pregnant women who smoke to quit (NICE’s Pathway on stop smoking interventions and services).
At the time of referral the pregnant woman should be given the number of an evidence-based stop smoking service. This may include the number of the NHS Pregnancy Smoking Helpline (0800 1699 169), details of the NHS smokefree website and a number for a local helpline if one is available.

Definitions

Fetal screening in accordance with current UK National Screening Committee programmes
The UK National Screening Committee (UKNSC) recommends all eligible pregnant women in England are offered fetal anomaly screening. The NHS fetal anomaly screening programme (NHS FASP) has responsibility for implementing this policy.
The combined test uses maternal age, gestational age calculated from the crown-rump length measurement, nuchal translucency measurement and two biochemical markers of pregnancy-associated plasma protein A (PAPP-A) and free beta human chorionic gonadotrophin hormone. The optimal time to perform the combined test is between 11 weeks 2 days and 14 weeks 1 day but a maternal blood specimen may be taken from 10 weeks onwards.
For women presenting too late for first trimester testing, the quadruple test (maternal age and four biochemical markers) window runs from 14 weeks 2 days to 20 weeks 0 days.
The fetal anomaly ultrasound scan should be offered to take place between 18 weeks 0 days and 20 weeks 6 days. [Adapted from Public Health England’s Fetal anomaly screening: programme handbook and Fetal anomaly screening standards]

Equality and diversity considerations

The offer and implications of screening should be understood by all women to enable them to make informed decisions. This will necessitate provision of information in an accessible format (particularly for women with physical, sensory or learning disabilities and women who do not speak or read English).

Pathway information

Person-centred care

People have the right to be involved in discussions and make informed decisions about their care, as described in your care.
Making decisions using NICE guidelines explains how we use words to show the strength (or certainty) of our recommendations, and has information about prescribing medicines (including off label use), professional guidelines, standards and laws (including on consent and mental capacity), and safeguarding.

Your responsibility

Guidelines

The recommendations in this guideline represent the view of NICE, arrived at after careful consideration of the evidence available. When exercising their judgement, professionals and practitioners are expected to take this guideline fully into account, alongside the individual needs, preferences and values of their patients or the people using their service. It is not mandatory to apply the recommendations, and the guideline does not override the responsibility to make decisions appropriate to the circumstances of the individual, in consultation with them and their families and carers or guardian.
Local commissioners and providers of healthcare have a responsibility to enable the guideline to be applied when individual professionals and people using services wish to use it. They should do so in the context of local and national priorities for funding and developing services, and in light of their duties to have due regard to the need to eliminate unlawful discrimination, to advance equality of opportunity and to reduce health inequalities. Nothing in this guideline should be interpreted in a way that would be inconsistent with complying with those duties.
Commissioners and providers have a responsibility to promote an environmentally sustainable health and care system and should assess and reduce the environmental impact of implementing NICE recommendations wherever possible.
