-Summary
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.

+Detailed description
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.
+Arms and interventions
| Arm | Type | Interventions | Description |
|---|
| Manual vacuum aspiration (MVA) | Experimental | Procedure: Manual vacuum aspiration (MVA) | Outpatient manual vacuum aspiration under local anesthesia and inhaled analgesia (MEOPA). |
| Electric aspiration in the operating room under general or regional anesthesia. Electric aspiration | Active comparator | Procedure: Electric aspiration (EA) | Electric aspiration in the operating room under general or regional anesthesia. Performed in the operating room under general or regional anesthesia, using an electric suction device and appropriate cannula. Post-procedure pelvic ultrasound to confirm complete evacuation. |
- Manual vacuum aspiration (MVA) (Procedure): Performed in consultation under local anesthesia and inhaled analgesia, using a manual vacuum aspirator and appropriate cannula. Post-procedure pelvic ultrasound to confirm complete evacuation.
- Electric aspiration (EA) (Procedure): Performed in the operating room under general or regional anesthesia, using an electric suction device and appropriate cannula. Post-procedure pelvic ultrasound to confirm complete evacuation.
+Outcome measures
Primary outcomes
- Incremental cost-utility ratio (ICUR) [3 months]: Incremental cost per quality-adjusted life year (QALY) gained of outpatient MVA compared to operating room EA, from a collective perspective.
Secondary outcomes
- Annual net financial benefit for health insurance over up to 5 years of different development scenarios for manual vacuum aspiration in consultation for the management of pregnancies terminated before 12 weeks of gestation [up to 5 years]: Annual net financial benefit for health insurance over up to 5 years of different development scenarios for manual vacuum aspiration in consultation for the management of pregnancies terminated before 12 weeks of gestation
