AB  - OBJECTIVE: Accurate amniocentesis-related pregnancy loss (ARL) rates for twin 
      gestations remains elusive because of varying ARL definitions in the literature. 
      We examined how OB/GYNs define/counsel women carrying twins about ARL. METHODS: A 
      random sample of 1000 American College of OB/GYN (ACOG) fellows and ACOG 
      Collaborative Ambulatory Research Network (CARN) members were mailed surveys 
      about their opinions/practice patterns regarding amniocentesis in twins. There 
      were 208/400 (52%) CARN members and 166/600 (27%) ACOG fellows who returned the 
      survey (37% response rate). RESULTS: Of respondents, 80.8% practiced general 
      OB/GYN, and 9.1% practiced maternal fetal medicine. Of respondents, 72% discussed 
      amniocentesis for prenatal diagnosis. Of these, 91.7% discuss the risk of ARL; 
      however, 47.4% do not quote an ARL rate. Of those who discuss ARL rates, 65% 
      quote a rate greater than for singletons. Regarding monochorionic-diamniotic 
      twins, 12.1% of respondents said the ARL rate was less, 39.6% said equal to, and 
      38.9% said greater than for dichorionic twins. Table 1 lists the most common 
      clinical definitions/time intervals used to describe ARL. CONCLUSION: Various 
      definitions/ARL rates are used when counseling about ARL in twins. Further 
      studies using a widely accepted definition of ARL are necessary to improve the 
      counseling of women considering amniocentesis for prenatal diagnosis in twins.
