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

27 juli 2026 uppdaterad av: Nantes University Hospital

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

The ASPIR study aims to evaluate the cost-utility of outpatient manual vacuum aspiration compared with operating room electric aspiration for the management of first-trimester miscarriage. It is hypothesized that manual aspiration will demonstrate equivalent clinical efficacy and patient quality of life while reducing healthcare costs.

Studieöversikt

Detaljerad beskrivning

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.
