Key Takeaways
- ACOG states that uterine aspiration is the preferred method when certain criteria for incomplete miscarriage are met, emphasizing high efficacy
- A randomized trial found misoprostol for missed miscarriage resulted in complete expulsion by day 7 in about 76%
- A large network meta-analysis of uterine evacuation vs medical management estimated that surgery has higher immediate completion rates than medical methods
- 80% of miscarriages occur before 12 weeks of pregnancy
- After 6 weeks of gestation, the miscarriage risk is reported as about 8% when fetal heart activity is present
- Miscarriage is estimated to occur in about 20% of clinically recognized pregnancies, and the rate increases with maternal age
- Single-gene and structural causes account for a minority share of miscarriages in genetic etiologies; chromosomal abnormalities are the largest group (~50%)
- Maternal smoking is associated with higher miscarriage risk; one meta-analysis found a pooled relative risk of ~1.23
- High maternal caffeine intake is associated with miscarriage risk; a meta-analysis found RR ~1.37 for high intake
- Loss of pregnancy is common; the US costs of care for pregnancy loss include clinician visits, ultrasounds, medications, and procedures, with economic impact documented in health-economics literature
- Hospital inpatient treatment costs for early pregnancy loss can be substantially higher than outpatient medical management in health-system cost models
- A systematic review of economic evaluations for miscarriage-related care identifies multiple cost components including hospitalizations, procedures, and medication
- In a US consumer survey, 72% of adults say they use the internet to search for health information
- Over 1.9 million people in the US had an app-enabled digital health visit recorded in 2022 (digital health usage is tracked by HIMSS/industry reporting)
- Telehealth use expanded rapidly; one federal report notes that in 2020, 80% of surveyed providers offered telehealth services
Miscarriage is common, especially before 12 weeks and after age 35, and rates rise with risk factors.

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
