The study was conducted to determine whether geographic location, primary specialty, attitudes and knowledge influence the prescribing habits of physicians regarding extended-use oral contraceptives (OC) and medically induced amenorrhea.
Practice characteristics, contraceptive prescription habits, menstrual cycle physiology knowledge and attitudes about medically induced amenorrhea of Oregon obstetrics and gynecology (OBGYN) and family medicine physicians were assessed using either a cross-sectional postal or electronic mail survey. Attitudes were assessed using a series of Likert-style questions; multiple-choice responses were used to evaluate knowledge and prescribing habits.
Of the 713 physicians in the sample (email 575, paper 138), 233 returned the survey, for an overall response rate of 32.7%. Over 90% (211/233) of respondents prescribed OCs; of these, 73.9% (155/211) stated that they prescribed extended-use OCs either often (23.5%) or sometimes (50.5%). Without adjusting for other factors, physicians reporting an OBGYN specialty (odds ratio [OR] 8.02, 95% confidence interval [CI]: 3.40-18.91) or an urban practice location (OR 2.75, 95% CI: 1.42-5.30) were more likely to report prescribing extended-use OCs. However, after adjusting for other factors, attitude was the only factor which remained significantly associated with prescribing (OR 1.85, 95% CI 1.41-2.42).
Physicians' attitudes regarding medically induced amenorrhea influence the use of extended-cycle OC more than any other characteristic.
本研究旨在确定地理位置、主要专业、态度和知识是否会影响医生对延长使用口服避孕药（OC）和医学诱导闭经的处方习惯。
使用横断面邮寄或电子邮件调查评估俄勒冈州妇产科（OBGYN）和家庭医学医师的实践特征、避孕处方习惯、月经周期生理学知识以及对医学诱导闭经的态度。使用一系列李克特式问题评估态度；使用多项选择回答评估知识和处方习惯。
在样本中的 713 名医生中（电子邮件 575 名，纸质 138 名），有 233 名医生返回了调查，总体回复率为 32.7%。超过 90%（211/233）的受访者开了 OC；其中，73.9%（155/211）表示他们经常（23.5%）或有时（50.5%）开延长使用 OC。在不调整其他因素的情况下，报告 OBGYN 专业（比值比[OR]8.02，95%置信区间[CI]：3.40-18.91）或城市实践地点（OR 2.75，95% CI：1.42-5.30）的医生更有可能开延长使用 OC。然而，在调整其他因素后，态度是唯一与处方显著相关的因素（OR 1.85，95% CI 1.41-2.42）。
医生对医学诱导闭经的态度比对其他任何特征更能影响延长周期 OC 的使用。
