To identify implementation challenges associated with conducting a randomized controlled trial (RCT) of group prenatal care (PNC) and report outcomes of the pilot.
A multi-site randomized pilot was conducted in Malawi and Tanzania between July 31, 2014, and June 30, 2015. Women aged at least 16 years with a pregnancy of 20-24 weeks were randomly assigned using sealed envelopes (1:1) to individual or group PNC. Structured interviews were conducted at baseline, in the third trimester and 6-8 weeks after delivery. The primary outcomes were attendance at four PNC visits and attendance at the 6-week postnatal visit.
The pilot showed that an RCT with individual randomization can be conducted in these two low-resource settings. Significantly more women in group PNC than in individual PNC completed at least four PNC visits (96/102 [94.1%] vs 53/91 [58.2%]) and attended the postnatal visit (76/102 [74.5%] vs 45/90 [50.0%]; both P<0.001).
Group PNC was feasible and associated with an increase in healthcare utilization and improved outcomes in Malawi and Tanzania. Lessons learned should be considered when designing large RCTs to determine efficacy. ClinicalTrials.gov: NCT02999334.
确定与群体产前护理(PNC)随机对照试验(RCT)相关的实施挑战,并报告试验的初步结果。
2014 年 7 月 31 日至 2015 年 6 月 30 日,在马拉维和坦桑尼亚进行了一项多地点随机试点研究。年龄至少 16 岁、妊娠 20-24 周的孕妇,采用密封信封(1:1)随机分配至个体或群体 PNC。在基线、孕晚期和产后 6-8 周进行结构性访谈。主要结局是参加四次 PNC 就诊和参加产后 6 周就诊。
该试点表明,在这两个资源有限的环境中,可以进行个体随机化 RCT。与个体 PNC 相比,群体 PNC 中完成至少四次 PNC 就诊的女性明显更多(96/102 [94.1%] 对 53/91 [58.2%]),并且参加了产后就诊(76/102 [74.5%] 对 45/90 [50.0%];均 P<0.001)。
群体 PNC 是可行的,并与马拉维和坦桑尼亚的医疗保健利用率增加和改善结局相关。在设计大型 RCT 以确定疗效时,应考虑到所获得的经验教训。ClinicalTrials.gov:NCT02999334。
