Low uptake of postpartum screening for Type 2 diabetes in women after a diagnosis of gestational diabetesPostpartum screening rates for Type 2 diabetes after a diagnosis of gestational diabetes are low across many high-income countries, ranging from 20 to 58% up to 1 year after delivery [1,2]. Subsequent annual follow-up rates plateau at 20% [1].We conducted an audit to assess postnatal diabetes screening rates in 233 women living in the city of Southampton with a history of gestational diabetes, diagnosed using WHO criteria. Current local practice involves giving verbal and written information regarding the risks of Type 2 diabetes after pregnancy at the initial consultation. After delivery and before discharge, all women are recommended to undergo postnatal glucose testing and are informed verbally and in writing to contact their general practitioner for annual ongoing screening. A copy of this letter is sent to the woman's general practitioner.The women included in our audit were aged 30.6 ± 5.2 years, 42.9% were from an Asian ethnic background and 39.9% were white. The mean BMI was 29.6 ± 7.2 kg/m 2 , with 28.6% of the women being overweight and 25.6% being obese.

A total of 80 women (34.3%) had glucose testing in the first year postpartum. The results for three women were consistent with a diagnosis of diabetes and another three women had impaired fasting glycaemia. Subsequently, 12.2%(16 of the 131 who were ≥2 years postpartum) and 17.8% (eight of the 45 who were ≥3 years postpartum) were screened 2 and 3 years after delivery, respectively. Two years after delivery, two women had elevated fasting plasma glucose levels and a further woman was diagnosed with Type 2 diabetes. Three years postpartum, one woman had impaired fasting glycaemia and another was diagnosed with Type 2 diabetes. Obese women were less likely to attend screening than women with a normal BMI (P=0.011). Screening rates varied by postcode district from 22.5 to 50.0%. There was no association between age, ethnicity, diabetes treatment during pregnancy or parity and the likelihood of glucose testing 1 year postpartum.In contrast to the high immediate postnatal diabetes screening rates in hospital, the low long-term rates of postpartum screening in women with a history of gestational diabetes represents a missed opportunity to prevent diabetes and its complications.The follow-up of gestational diabetes crosses the divide between primary and secondary care and involves two secondary care specialities, diabetes and obstetrics. A proportion of women may therefore be lost because of ambiguity between primary and secondary care responsibilities for postnatal screening [1]. Poor communication and a lack of agreed universal protocols across primary and secondary care have previously accounted for poor interdiscip...
