title: Antenatal screening and predicting hypertension in pregnancy for midwives.
abstract: BACKGROUND
  The cause of hypertension in pregnancy remains unknown and results in increased risk of complications for mother and baby. Symptoms of developing pre-eclampsia, such as an elevated blood pressure, can be vague and singular. The purpose of this literature review is to evaluate research investigating antenatal screening practices for hypertension which fall within the midwives scope of practice.
  
  
  METHODS
  Inclusion criteria for this literature review were English language, peer reviewed primary research journal articles, published in the previous 20 years where the population under study was pregnant with reported outcomes of prevention, screening or prediction of hypertension in pregnancy. A large number of papers (n=201) were identified and these were screened and subsequently excluded if they addressed diagnostic testing, screening and interpretation that depended solely on a medical practitioner.
  
  
  RESULTS
  There was no single predictive factor found, however the relevant papers included in this review (n=33) found evidence of modifiable, non-modifiable and clinical assessment factors for inclusion in a midwifery screening model.
  
  
  CONCLUSIONS
  Further research should be focused on the factors observed by midwives during history taking and the antenatal course in the second and third trimesters and whether or not these can be synthesised in to a hypertension-specific diagnostic tool for use in midwifery practice.
