Online recruitment of atopic dermatitis patients using Facebook may be effective, according to the results of a study published in the Journal of the European Academy of Dermatology and Venereology.
In the 4-week non-interventional adherence study, researchers recruited adults with self-reported atopic dermatitis living near Aarhus and Copenhagen in Denmark. Participants were recruited between May and August 2017 through a website home page.
Study authors paid to advertise a website link on Facebook and sent flyers with the webpage’s QR code to patient waiting areas in 3 outpatient dermatology wards. Participants completed a questionnaire on the website as a pre-selection. They also completed the Patient-Oriented Eczema Measurement Questionnaire (POEM) via phone calls and scheduled 2 clinic visits.
Researchers spent $ 10,064 during 53 active recruiting days on Facebook, for an average of $ 190 per day. The homepage saw 3,932 visits, of which 93% were from Facebook paid advertising, 0.3% from Google, 6% directly from the website and 0.2% from the QR code.
A total of 118 participants were considered eligible, and the cost of recruiting per eligible participant was $ 85. Of this group, 96 patients attended a first visit and were included, resulting in a cost per enrolled participant of $ 105.
In addition, 12 participants did not attend the second visit, resulting in 83 graduates and a cost of $ 121 per graduating participant. The graduates were recruited in 53 days, or 1.6 participants recruited per day.
Of the participants enrolled, 67.4% were female, 33% were between the ages of 18 and 25, and 36% were between the ages of 26 and 35. Additionally, the researchers reported that 18% had mild illness, 50% had moderate illness, and 22% had severe illness according to POEM. Using the EASI (Eczema Area and Severity Index) score, 42% were considered mild, 27% moderate and 7% severe. Additionally, 3% had fair skin and 20% had near fair skin.
The study authors noted that their study costs were likely affected by geographic limitations and 2 clinic visits. In addition, most of the participants had mild atopic dermatitis and were recruited from a hospital, including clinics and outpatient departments, usually resulting in the recruitment of patients with moderate to severe disease severity, have- they recognized.
“Online recruitment could be a useful addition to traditional recruitment to enable the recruitment of participants from the full scale of disease severity,” the investigators commented.
