To evaluate the effect of structured contraceptive counselling on the uptake of long-acting reversible contraceptives (LARCs) and pregnancy rates.
Cluster randomised trial.
Abortion, youth and maternal health clinics in Stockholm, Sweden.
Sexually active women aged ≥18 years without a wish for pregnancy seeking abortion and/or contraceptive counselling.
For participants in clinics randomised to intervention, trained healthcare providers implemented a study-specific intervention package designed for structured contraceptive counselling. Participants in the control clinics received routine counselling.
The primary outcome was choice of LARCs at first visit. Secondary outcomes were LARC initiation at 3 months and pregnancy rates at 3 and 12 months. We used logistic mixed-effects models with random intercept for clinic to account for clustering.
From September 2017 to May 2019, 28 randomised clinics enrolled 1364 participants. Analyses including 1338 subjects showed that more participants in the intervention group compared with the control group chose LARCs: 267/658 (40.6%) versus 206/680 (30.3%) (OR 2.77, 95% CI 1.99-3.86). LARC initiation was higher in the intervention group compared with the control group: 213/528 (40.3%) versus 153/531 (28.8%) (OR 1.74, 95% CI 1.22-2.49). At the abortion clinics, the pregnancy rate was significantly lower at 12 months in the intervention group compared with the control group: 13/101 (12.9%) versus 28/103 (27.2%) (OR 0.39, 95% CI 0.18-0.88).
Structured contraceptive counselling increased LARC uptake in all clinics and significantly reduced unintended pregnancy rates in abortion clinics at the 12 months follow-up.
Structured contraceptive counselling increased LARC uptake and reduced pregnancy rates at 12 months.
评估结构化避孕咨询对长效可逆避孕方法(LARC)的采用情况及妊娠率的影响。
整群随机试验。
瑞典斯德哥尔摩的堕胎、青少年及孕产妇健康诊所。
年龄≥18岁、无妊娠意愿且寻求堕胎和/或避孕咨询的性活跃女性。
对于被随机分配至干预组诊所的参与者,经过培训的医疗服务提供者实施了一项专门为结构化避孕咨询设计的干预方案。对照诊所的参与者接受常规咨询。
主要结局为首次就诊时对LARC的选择。次要结局为3个月时开始使用LARC以及3个月和12个月时的妊娠率。我们使用带有诊所随机截距的逻辑混合效应模型来考虑聚类情况。
2017年9月至2019年5月,28个随机分组的诊所招募了1364名参与者。纳入1338名受试者的分析显示,与对照组相比,干预组中选择LARC的参与者更多:267/658(40.6%)对206/680(30.3%)(比值比2.77,95%置信区间1.99 - 3.86)。干预组开始使用LARC的比例高于对照组:213/528(40.3%)对153/531(28.8%)(比值比1.74,95%置信区间1.22 - 2.49)。在堕胎诊所,干预组12个月时的妊娠率显著低于对照组:13/101(12.9%)对28/103(27.2%)(比值比0.39,95%置信区间0.18 - 0.88)。
结构化避孕咨询增加了所有诊所对LARC的采用,并在12个月随访时显著降低了堕胎诊所的意外妊娠率。
结构化避孕咨询增加了LARC的采用并降低了12个月时的妊娠率。
