Input: We included seven trials with 1521 participants in this review. The expectant-care group was more likely to have an incomplete miscarriage by two weeks (RR 3.98; 95% CI 2.94 to 5.38) or by six to eight weeks (RR 2.56; 95% CI 1.15 to 5.69). The need for unplanned surgical treatment was greater for the expectant-care group (RR 7.35; 95% CI 5.04 to 10.72). The mean percentage needing surgical management in the expectant-care group was 28%, while 4% of the surgical-treatment group needed additional surgery. The expectant-care group had more days of bleeding (MD 1.59; 95% CI 0.74 to 2.45). Further, more of the expectant-care group needed transfusion (RR 6.45; 95% CI 1.21 to 34.42). The mean percentage needing blood transfusion was 1.4% for expectant care compared with none for surgical management. Results were mixed for pain. Diagnosis of infection was similar for the two groups (RR 0.63; 95% CI 0.36 to 1.12), as were results for various psychological outcomes. Pregnancy data were limited. Costs were lower for the expectant-care group (MD -499.10; 95% CI -613.04 to -385.16; in UK pounds sterling). Expectant management led to a higher risk of incomplete miscarriage, need for unplanned (or additional) surgical emptying of the uterus, bleeding and need for transfusion. Risk of infection and psychological outcomes were similar for both groups. Costs were lower for expectant management. Given the lack of clear superiority of either approach, the woman's preference should be important in decision making. Pharmacological ('medical') management has added choices for women and their clinicians and has been examined in other reviews.
Output:

We searched for randomized trials that compared waiting versus surgery for miscarriage. In addition, we looked at reference lists to find trials. We also wrote to researchers to find more studies. Seven trials with 1521 women looked at waiting versus surgery for miscarriage. More women who waited for the miscarriage to complete on its own had tissue left in the womb. This was studied at two weeks and at six to eight weeks. More of these women needed surgery to complete the process. These women also had more days of bleeding. Some needed to be given blood, compared with none in the surgery group. Both groups had about the same numbers of infections. Results were mixed for pain. Mental health also seemed about the same for both treatment groups. Costs were lower for waiting than for surgery. Overall, no strong medical results argue for either approach. Information was limited on future pregnancy. One trial was large, while the others had small numbers of women. What the woman prefers should be the major concern. Drug treatment (such as with misoprostol and mifepristone) has added choices for women and their clinicians, and has been studied in other reviews.
