An in-depth analysis of numbers of obstetric and gynecologic operations from 1979 to 1984 was performed using data from the National Center for Health Statistics. During the study period, there was a decrease in total numbers of obstetric and gynecologic procedures of 1%. During the same five-year period the numbers of physicians who label themselves as obstetrician-gynecologists increased 22%. In 1983, a total of 809,000 cesarean sections were performed. It has become the most common hospital-based operation in this country. Twenty-one percent of all live births are now by cesarean section. The second most common obstetric and gynecologic operation is hysterectomy (673,000), and diagnostic dilation and curettage of uterus (632,000) third. These operations are also the second and third most common procedures performed in the United States. In 1983, obstetric and gynecologic operations represented 23% of all surgery completed in this country. These figures demonstrate the dynamics of obstetric and gynecologic surgical practice. They show that numbers of obstetric and gynecologic operations have decreased over the last five years, in spite of constantly increasing numbers of obstetrician-gynecologists. If current trends continue, future individual operative workloads, on average, will decrease with possible adverse effects on quality of obstetric-gynecologic surgical care.
利用国家卫生统计中心的数据，对1979年至1984年期间的妇产科手术数量进行了深入分析。在研究期间，妇产科手术的总数下降了1%。在同一五年期间，自称妇产科医生的人数增加了22%。1983年，共进行了80.9万例剖宫产手术。它已成为该国最常见的住院手术。现在，所有活产中有21%是通过剖宫产进行的。第二常见的妇产科手术是子宫切除术（67.3万例），子宫诊断性刮宫术（63.2万例）位居第三。这些手术也是美国第二和第三常见的手术。1983年，妇产科手术占该国所有完成手术的23%。这些数字表明了妇产科手术实践的动态变化。它们表明，尽管妇产科医生的数量不断增加，但在过去五年中，妇产科手术的数量却有所下降。如果目前的趋势继续下去，未来个体手术工作量平均将会减少，这可能会对妇产科手术护理质量产生不利影响。
