Effects of technology-based contraceptive decision aids: a systematic review and meta-analysis

This study aimed to conduct a systematic review and meta-analysis of the effects of technology-based decision aids on contraceptive use, continuation, and patient-reported and decision-making outcomes.

A systematic search was conducted in OVID MEDLINE, Cochrane Database of Systematic Reviews, CENTRAL, CINAHL, Embase, PsycINFO, and SocINDEX databases from January 2005 to April 2022. Eligible references from a concurrent systematic review evaluating contraceptive care were also included for review.

Studies were included if a contraceptive decision aid was technology-based (ie, mobile/tablet application, web, or computer-based) and assessed contraceptive use and/or continuation or patient-reported outcomes (knowledge, self-efficacy, feasibility/acceptability/usability, decisional conflict). The protocol was registered under the International Prospective Register of Systematic Reviews (CRD42021240755).

Three reviewers independently performed data abstraction and quality appraisal. Dichotomous outcomes (use and continuation) were evaluated with an odds ratio, whereas continuous outcomes (knowledge and self-efficacy) were evaluated with the mean difference. Subgroup analyses were performed for the mode of delivery (mobile and tablet applications vs web and computer-based) and follow-up time (immediate vs >1 month).

This review included 18 studies evaluating 21 decision aids. Overall, there were higher odds of contraceptive use and/or continuation among decision aid users compared with controls (odds ratio, 1.27; 95% confidence interval, [1.05-1.55]). Use of computer and web-based decision aids was associated with higher odds of contraceptive use and/or continuation (odds ratio, 1.36; 95% confidence interval, [1.08-1.72]) than mobile and tablet decision aids (odds ratio, 1.27; 95% confidence interval, [0.83-1.94]). Decision aid users also had statistically significant higher self-efficacy scores (mean difference, 0.09; 95% confidence interval, [0.05-0.13]), and knowledge scores (mean difference, 0.04; 95% confidence interval, [0.01-0.07]), with immediate measurement of knowledge having higher retention than measurement after 1 month. Other outcomes were evaluated descriptively (eg, feasibility, applicability, decisional conflict) but had little evidence to support a definite conclusion. Overall, the review provided moderate-level evidence for contraceptive use and continuation, knowledge, and self-efficacy.

The use of technology-based contraceptive decision aids to support contraceptive decision-making has positive effects on contraceptive use and continuation, knowledge, and self-efficacy. There was insufficient evidence to support a conclusion about effects on other decision-making outcomes.
