The Blue Journal Club is an international journal club on women’s health research based on Twitter (as @BlueJCHost). We start our conversation on the last Wednesday of every month and use the hashtag #BlueJC for our tweets. Simply add this hashtag (“#BlueJC”) to each tweet and we will capture it. Each #BlueJC opens for 7 days with an advertised start time. All BJOG #BlueJC papers also have complementary slide sets suitable for face-to-face journal clubs with your local colleagues. You can access the slide set of this paper here (find the title paper and click on the “discussion point” tab).
The discussion points are attached below (quoted from the published manuscript)
A midwife referred an African-Caribbean woman at 33 weeks of her first pregnancy because of ‘large for dates’ on abdominal palpation (symphysis fundal height= 37cm).
Her oral glucose tolerance test at 28 weeks was normal. She is overweight (body mass index= 27 kg/m2), but has no other risk factors. She has no family history of obstetrics complication. How would you counsel this woman?
Description of research
|Participants||Women with a singleton pregnancy|
|Intervention||2D or 3D ultrasound scan or MRI performed in the third trimester to detect fetal macrosomia.|
|Comparison||Another index test (if used)|
|Outcomes||Birthweight >4000 g, >4500 g, >90th or >95th centile|
|Study design||Systematic review and meta-analysis|
- How common is macrosomia in your practice?
- How do you currently counsel women similar to the one in the scenario?
- How did the authors assess the quality of individual studies? (also see suggested reading
- What were the problems identified by their quality assessment of individual studies?
- Critically appraise this meta-analysis using the PRISMA checklist (http://bit.ly/1CIZNHw).
- Can you briefly summarise the results of this study as a one-sentence take-home message
- Would the results of this study influence your management of the woman in the scenario
- How would the results of this study influence your daily practice?
