Recruitment of black and Latina women to a randomized controlled trial

Minority women are often not adequately represented in randomized controlled trials, limiting the generalizability of research trial results.

We implemented a recruitment strategy for a postpartum depression prevention trial that utilized patient feedback to identify and understand the recruitment barriers of black and Latina postpartum women. Feedback on patients' reasons for trial refusal informed adaptations to the recruitment process. We calculated weekly recruitment rates and analyzed qualitative and quantitative data from patient refusals.

Of the 668 women who were approached and completed the consent process, 540 enrolled in the trial and 128 declined participation. Over 52-weeks of recruitment, refusal rates decreased from 40% to 19%. A taxonomy of eight reasons for refusal derived from patient responses identified barriers to recruitment and generated targeted revisions to the recruitment message.

A recruitment strategy designed to incorporate and respond to patient feedback improved recruitment of Black and Latina women to a clinical trial.
