- Understanding and Addressing Disparities in Vaccination Rates among Black Members
Goal: The aim of this study is to identify factors contributing towards differences in vaccination rates among KP members in two KP regions, Georgia and Mid-Atlantic States. Patient-related factors will be identified from existing data in the electronic medical record and from new cross-sectional survey and semi-structured interviews with members. Information gleaned from this research project will help KP identify factors, beliefs and attitudes contributing towards racial disparities in vaccination rates and will lay the groundwork for developing interventions to improve vaccination rates.

- Preferences for Social Needs Screening During Pregnancy
Goal: This study explores preferences for social needs screening among pregnant women including preferences for modality of screening, whether that differs by domain of screening or by personal circumstances and characteristics, and whether women are amenable to being screened and referred for social needs as a part of pregnancy care. The findings will be used to make recommendations for optimizing acceptability of social needs screening for pregnant women.

- Effects of Virtual Visit Utilization on In-Person Visit Utilization and Treatment Adherence: A Multi-site Retrospective Cohort Study
Goal: The objectives of this major study are to understand the impact of implementation of virtual visits (e.g., video visits, phone visits, and synchronous chats) on in-person visit utilization (e.g., substitution versus inducement), to understand who selects virtual versus in-person visits, and to examine how visit mode influences provider and patient behaviors (e.g., orders for and compliance with ancillary services).
