Abstract
Introduction
To evaluate the clinical and economic impact of healthcare management of pregnant women with blood pressure increase (BPI) accessing emergency room (ER) and the utility of the introduction of a PlGF-based test in clinical practice.
Materials and methods
This retrospective cohort study included women with single pregnancies who performed at least 1 ER access for BPI after the 20th gestational week in 2016. BPI was subsequently classified as significant if associated with preeclampsia (PE) or Fetal Growth Restriction (FGR) and not significant otherwise. Two experts evaluated potential changes in patients’ management with the introduction of a PlGF-based test. The direct healthcare cost was estimated.
Results
We enrolled 107 patients, of which 30% showed significant BPI (17 PE cases, 13 FGR, and 2 both pathologies). Anamnestic, clinical, and laboratory evaluations were not effective in differentiating between significant and not significant BPI (p-values: .8320, .2856, and .2297, respectively). The introduction of a PlGF-based test would have reduced overtreatment and undertreatment. The test would have avoided 18% of all hospitalizations, 35% of hospitalizations for BPI, 43% of outpatient referrals, and 13% of ER accesses. The number of avoidable accesses was higher in women with not significant BPI. Overall, the mean total cost (from first ER access until delivery) was €2634 per woman and €401 would have been avoidable.
Conclusion
The clinical integration of PlGF-based tests is advantageous in diagnostic, prognostic and economic terms, as an objective marker of placental dysfunction.
