We conducted a systematic review of the effectiveness of electronic health education tools designed to improve knowledge, attitudes or practices related to contraception.
Eligible studies consisted of English-language reports published after 1990 that quantified the effects of an electronic intervention on any of the following outcomes: contraceptive knowledge, attitude toward contraceptives, contraceptive method choice, contraceptive use or pregnancy. We conducted a systematic search of multiple electronic databases including MEDLINE, Global Health, Academic Search Complete, Cochrane Library and Grey Literature Report. We followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for reporting.
Of 143 full-text reports assessed for eligibility, 13 studies described in 16 reports were eligible for inclusion. Of six studies that evaluated video interventions, all were randomized controlled trials, and four reported any statistically significant difference between intervention groups on knowledge, method choice or pregnancy. Of seven studies of interactive computer applications, five were randomized controlled trials, and two were nonrandomized comparison studies. Four of these seven studies found statistically significant difference between study arms in contraceptive knowledge, attitudes or contraceptive use. While most differences favored the intervention, effects were generally limited with respect to clinical relevance and the number of outcomes impacted.
Published assessments of electronic interventions for improving contraception-related outcomes are limited. Formal evaluations of interventions and publication of results are needed to determine the efficacy of electronic tools for contraceptive education and guide development of new interventions.
我们对旨在提高与避孕相关的知识、态度或实践的电子健康教育工具的有效性进行了系统评价。
符合条件的研究包括 1990 年后发表的英语报告，这些报告量化了电子干预对以下任何结果的影响：避孕知识、对避孕的态度、避孕方法选择、避孕使用或怀孕。我们对多个电子数据库进行了系统搜索，包括 MEDLINE、全球健康、学术搜索完整、Cochrane 图书馆和灰色文献报告。我们遵循系统评价和荟萃分析报告的首选报告项目指南。
在评估合格性的 143 篇全文报告中，有 16 篇报告中描述的 13 项研究符合纳入标准。在评估视频干预的六项研究中，所有研究均为随机对照试验，其中四项报告了干预组之间在知识、方法选择或怀孕方面的任何统计学显著差异。在七项交互式计算机应用研究中，有五项为随机对照试验，两项为非随机对照研究。这七项研究中有四项发现研究臂之间在避孕知识、态度或避孕使用方面存在统计学显著差异。虽然大多数差异有利于干预，但就临床相关性和受影响的结果数量而言，效果通常有限。
关于改善避孕相关结局的电子干预措施的已发表评估有限。需要对干预措施进行正式评估并公布结果，以确定电子工具在避孕教育中的功效，并指导新干预措施的开发。
