Cost-utility Analysis of Outpatient Manual Vacuum Aspiration Versus Operating Room Electric Aspiration for the Management of First-trimester Miscarriage (ASPIR)
Cost-utility Analysis of Outpatient Manual Vacuum Aspiration Versus Operating Room Electric Aspiration for the Management of First-trimester Miscarriage (ASPIR Study)

Descripción detallada
Miscarriage occurs in approximately 15% of pregnancies during the first trimester. In France, surgical management usually involves electric aspiration in the operating room under anesthesia, associated with hospital admission. Manual vacuum aspiration (MVA) is widely used in low-resource settings and for induced abortion, with demonstrated safety and patient satisfaction. This multicenter randomized controlled trial compares outpatient MVA under local anesthesia and inhaled analgesia versus electric aspiration (EA) under anesthesia in the operating room.
The primary objective is to assess the incremental cost-utility ratio (ICUR, cost per QALY) at 3 months. Secondary outcomes include complications, pain, satisfaction, quality of life, and fertility at 12 months. The study anticipates enrolling 860 participants across multiple centers in France.
