Assessing recruitment and retention activities needed to enroll women identified through community-based programs (such as the Women, Infants, and Children (WIC) program) into a randomized controlled clinical trial on nurse-delivered contraceptives in the home. The majority of women in this study had low socioeconomic status indicators and low levels of education, and the majority were young.
Recruitment sources and number of contact-attempts were collected and analyzed. Full time equivalents needed to undertake these activities were estimated.
Two hundred and forty five women were identified in recruiting and enrolling 103 study participants involving 1,232 contact-attempts. Self-referral had the highest ratio of referrals to enrollees (55.6%), while this ratio was the lowest for community outreach (33.3%). Retention activities succeeded in maintaining over 90% of the sample. Ninety-two percent of English-speaking participants completed the study versus 79% of Spanish-speaking participants. The time expenditure per enrollee was 10.4 hours for recruitment and 1.2 hours for retention, with an estimated cost per enrollee of $324.03 for recruitment and $39.14 for retention. More retention activities were required to maintain women in the comparison group than in the intervention group.
评估将通过社区项目（如妇女、婴儿和儿童（WIC）项目）识别出的女性纳入一项关于护士上门提供避孕药具的随机对照临床试验所需的招募和留存活动。本研究中的大多数女性社会经济地位指标较低且教育水平较低，并且大多数较为年轻。
收集并分析招募来源和联系尝试次数。估算开展这些活动所需的全职等效人员数量。
在招募和登记103名研究参与者的过程中，共进行了1232次联系尝试，识别出245名女性。自我推荐的推荐人与入选者的比例最高（55.6%），而社区推广的这一比例最低（33.3%）。留存活动成功地使超过90%的样本得以留存。92%的说英语的参与者完成了研究，而说西班牙语的参与者这一比例为79%。每位入选者的招募时间花费为10.4小时，留存时间花费为1.2小时，估计每位入选者的招募成本为324.03美元，留存成本为39.14美元。与干预组相比，对照组需要更多的留存活动来留住女性。
