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.
