The HER Salt Lake media campaign: comparing characteristics and outcomes of clients who make appointments online versus standard scheduling.

<bold>Background: </bold>Little research has examined how media outreach strategies affect the outcomes of contraceptive initiatives. Thus, this paper assesses the potential impact of an online media campaign introduced during the last six months of a contraceptive initiative study based in Salt Lake City, UT (USA).<bold>Methods: </bold>During the last six months of the HER Salt Lake Contraceptive Initiative (September 2016-March 2017), we introduced an online media campaign designed to connect potential clients to information about the initiative and a brief (9-item) appointment request form (via HERsaltlake.org). Using linked data from the online form and electronic medical records, we examine differences in demographics, appointment show rates, and contraceptive choices between "online requester" clients who made clinical appointments through the online form (n = 356) and "standard requester" clients who made appointments using standard scheduling (n = 3,051). We used summary statistics and multivariable regression to compare groups.<bold>Results: </bold>The campaign logged 1.7 million impressions and 15,765 clicks on advertisements leading to the campaign website (HERSaltLake.org). Compared to standard requesters, online requesters less frequently reported a past pregnancy and were more likely to be younger, white, and to enroll in the survey arm of the study. Relative to standard requesters and holding covariates constant, online requesters were more likely to select copper IUDs (RRR: 8.14), hormonal IUDs (RRR: 12.36), and implants (RRR: 10.75) over combined hormonal contraceptives (the contraceptive pill, patch, and ring). Uptake of the contraceptive injectable, condoms, and emergency contraception did not differ between groups.<bold>Conclusion: </bold>Clients demonstrating engagement with the media campaign had different demographic characteristics and outcomes than those using standard scheduling to arrange care. Online media campaigns can be useful for connecting clients with advertised contraceptive methods and initiatives. However, depending on design strategy, the use of media campaigns might shift the demographics and characteristics of clients who participate in contraceptive initiatives.<bold>Trial Registration: </bold>Clinicaltrials.gov identifier NCT02734199, Registered 12 April 2016-Retrospectively registered, https://clinicaltrials.gov/ct2/show/NCT02734199 .
