Intrauterine pregnancy of uncertain viability (IPUVI) affects 30% of women seen in the Early Pregnancy Assessment Unit (EPAU). Such women have a pregnancy within the uterus on ultrasound but do not meet ultrasound criteria to confirm an ongoing pregnancy. This may represent a normally developing (early) pregnancy (50%) or a failing pregnancy ending in a miscarriage. Following The National Institute for Health and Care Excellence (NICE) Guideline 154 (2012), women need a confirmatory ultrasound after two weeks. This interval is particularly distressing for women and diagnostic uncertainty in early pregnancy is associated with heightened levels of anxiety and depression. NICE Evidence Update 71 (2014) suggests that provision of more information about the likely outcome of the pregnancy (prior to the repeat ultrasound) may benefit psychological health.
