In addition, the PVI will enable doctors to avoid unnecessary interventions. "Every woman attending a unit with a threatened miscarriage has initial blood tests and a scan as part of her care. Additionally, some women are subjected to repeated blood tests and ultrasound scans to monitor the pregnancy. The use of the PVI will negate these in the vast majority (80%) of these women, as we will be able to reassure them of a high likelihood of pregnancy continuation and that there is little additional value in doing further testing. Furthermore, psychological counselling and support could be targeted at the women most likely to miscarry, in order to reduce anxiety levels and improve their overall experience," she said.
"The PVI will facilitate further investigations of the remaining 20% of these pregnancies that do go on to miscarry, and we are hopeful that by identifying factors that impact significantly on pregnancy outcome we will be able to gain a better understanding of the process of threatened miscarriage. This, in turn, may enable us to design more effective interventions to rescue these pregnancies.
"We were limited by the size of our study and feel that further enhancements can be made to the PVI in a larger definitive study in which we could include more of the six factors that we have found to be important in miscarriage."
Dr Adam and her colleagues are seeking funding to validate the PVI model in a larger research trial of 1000 women with threatened miscarriage."
No additional equipment is required in the clinic in order to use the PVI. "This is the huge attraction of the PVI. It lends itself to widespread adoption because it is simple, inexpensive and reproducible, without the need for sophisticated equipment or gadgets," said Dr Adam.
