To compare the use of episiotomy by private practitioners vs. resident staff and to determine if number of years in practice influences episiotomy use.
A retrospective chart review of vaginal deliveries at 35 weeks or greater between January 2001 and June 2001. The number of years in practice by each private physician was documented. Independent sample t tests and chi2 tests were used to analyze data.
In 995 deliveries, episiotomies were performed in 6% of low-risk resident deliveries vs. 26% of low-risk private deliveries (p<0.001). Physicians in practice > or = 15 years performed episiotomies in 32% of low-risk births. Physicians in practice <15 years performed episiotomies in 22% of low-risk births (p = 0.027).
Deliveries performed by private practitioners are associated with a higher rate of episiotomy than those by resident staff. The number of episiotomies appears to increase by number of years in practice.
比较私人执业医生与住院医生进行会阴切开术的情况，并确定执业年限是否会影响会阴切开术的使用。
对2001年1月至2001年6月期间孕周35周及以上的阴道分娩进行回顾性病历审查。记录每位私人医生的执业年限。采用独立样本t检验和卡方检验分析数据。
在995例分娩中，低风险住院分娩的会阴切开率为6%，而低风险私人执业分娩的会阴切开率为26%（p<0.001）。执业15年及以上的医生在32%的低风险分娩中进行了会阴切开术。执业年限不足15年的医生在22%的低风险分娩中进行了会阴切开术（p = 0.027）。
私人执业医生进行的分娩与会阴切开率高于住院医生相关。会阴切开术的数量似乎随执业年限的增加而增加。
