Abstract 4147618: Modality of Research Engagement Among Postpartum Women with Hypertension and High Health-Related Social Needs

Circulation, Volume 150, Issue Suppl_1, Page A4147618-A4147618, November 12, 2024. Introduction:People of color and non-English speakers are underrepresented in research and disproportionately affected by health-related social needs (HRSNs). Research engagement can be particularly challenging after pregnancy as postpartum care attendance is low. We describe our experience with remote recruitment modalities in a such a population.Methods:The study population included all patients affected by hypertension during a pregnancy who delivered at a large safety-net hospital 1/2022-6/2023. These patients also engaged in 6 weeks of remote blood pressure monitoring postpartum. Patients were contacted between 6 weeks and 12 months post-delivery to complete an online survey regarding HRSNs and provide consent to link survey data to clinical data. The recruitment protocol included initial outreach via the electronic medical record (EMR) patient portal, if available, or else a hard copy letter via mail, followed by a series of text messages then phone calls. All communication was conducted in the patient’s primary language (English, Spanish, or Haitian Creole).Results:We recruited 148 (9.4%) of 1571 patients contacted. Respondents were 51% Black, 39% Latina, 26% White. Table illustrates the comparable rate of recruitment across languages, dominance of EMR as mode of engagement and an illustration of the high rate of complex HRSN among our participants. The most effective recruitment method was EMR communication (57% of total recruitment) followed by text messages (28%). Our Haitian Creole-speaking respondents had the highest rates of HRSN – possibly representing the Haitian migrant crisis affecting Boston in this time period – as well as the highest rate of engaging via EMR messaging. Other domains of HRSN were high among all language groups including trouble affording medication (11-23%) and heating/electric access (21-34%).Conclusions:A diverse postpartum population with a high prevalence of HRSNs is hard to engage in research. Despite presumed digital barriers, EMR and secure text were effective and secure methods of online survey recruitment. Future studies seeking to understand the intersection of health outcomes and HRSNs should consider adding recruitment with EMR to common texting strategies.
